%X Although modern ease of access to technology enables many of us to
obsessively document our lives, much of the captured digital content is often
disregarded and forgotten on storage devices, with no concerns of cost or
decay. Can we design technology that helps people better appreciate captured
memories? What would people do if they only had one more chance to relive past
memories? In this paper, we present a prototype design, PY-ROM, a
matchstick-like video recording and storage device that burns itself away after
being used. This encourages designers to consider lifecycles and human-computer
relationships by integrating physical properties into digitally augmenting
everyday objects.

%X We present a novel playground platform that will hopefully help in
countering two important issues in children in the developed world: lack of
physical activity and lack of socialization. The system underlying the platform
will eventually adapt automatically to and modulate the amount of physical
activity of children by applying a new notion in interaction: that of
"interaction tempo". The concept of beats per minute seems especially adequate
as the base structure of a physically-based activity. As an exertion interface
we expect that, through the design of collaborative experiences, it will also
enhance socialization of children.

biology concepts because graphical and symbolic interfaces do not allow users
to intuitively manipulate complex physical forms. Actuated, tangible tools may
enhance understanding at all levels of protein study. To advance TUI awareness
of protein study, we present an overview of protein concepts and current
protein study tools. Thirty-six protein researchers, engineers, professors and
students recommend design guidelines for tangible interfaces in protein study,
and we outline research directions for TUIs to improve protein study at all
educational levels.

%* (c) Copyright 2009 ACM
%W http://doi.acm.org/10.1145/1520340.1520345
%X This paper explores the concept of somaesthetics as an approach to the
design of expressive interaction. This concept is exemplified through the
design process of soft(n), an interactive tangible art installation developed
in conjunction with V2_Lab in Rotterdam. Somaesthetics is a term coined by
Richard Shusterman, a pragmatist philosopher interested in the critical study
of bodily experience as a focus of sensory-aesthetic appreciation and agency.
In the context of interaction, somaesthetics offers a bridging strategy between
embodied practices based in somatics, and the design of an aesthetics of
interaction for HCI. This paper argues for the value of exploring design
strategies that employ a somaesthetic approach, presents a definitional
framework of somaesthetics that can be applied to interaction, and links the
concept of somaesthetics to a specific design case in which tactile interaction
is applied to the design of a networked, tangible interactive artwork called
soft(n).

%X Stress OutSourced (SOS) is a peer-to-peer network that allows anonymous
users to send each other therapeutic massages to relieve stress. By applying
the emerging concept of crowdsourcing to haptic therapy, SOS brings physical
and affective dimensions to our already networked lifestyle while preserving
the privacy of its members. This paper first describes the system, its three
unique design choices regarding privacy model, combining mobility and
scalability, and affective communication for an impersonal crowd, and contrasts
them with other efforts in their respective areas. Finally, this paper
describes future work and opportunities in the area of haptic social networks.

%X The field of HCI has played an important role in broadening the spectrum of
users of computational artifacts. However, users with extreme preferences are
mostly ignored by the designers and researchers because they do not constitute

In order to further discuss these concerns, this paper introduces a case about
the extreme users and the challenges they face. The paper ends with discussing
future directions and challenges in designing for all users in the field of

%X What happens to human-computer "interaction" when the human user is no
longer alive? This exploratory paper uses insights from the critical humanist
tradition to argue for the urgent need to consider the facts of mortality,
dying, and death in HCI research. Using an interdisciplinary approach, we
critically reflect upon how the intersection of death and computing is
currently navigated and illustrate the conceptual and practical complexities
presented by mortality, dying, and death in HCI. Finally, we introduce the
concept of thanatosensitivity to describe an approach that actively integrates
the facts of mortality, dying, and death into HCI research and design.

%X The importance of love is reflected in literature, movies and music,
therefore it seems necessary to understand what role technology plays in
relation to love and the roles it could to play in the future. We review
studies related to Love in HCI and we identify a lack of consideration of
philosophy as a background for love understanding. Based on literature review,
we offer a proposal of guidelines for designing technology that aims to improve
loving relationships. Besides, we explore principles of engagement with
technology that may be important when designing love-promoting technology.
Finally we propose a practical design example.

received little attention in HCI. In this paper we describe a study of the uses

but that TV is still a richly social experience -- not as communal watching,
but instead through communication around television programs. We explore new
possibilities for technology-based interaction around television.

%X People who use the Internet for health information often obtain their first
opinion that way, and then, if they go to a doctor, the doctor's advice is
relegated to the second opinion. Using the Internet, or Dr. Google, as a first
opinion can be problematic due to misinformation, misinterpretation of valid
information, and the fears that can arise due to lack of medical knowledge,
inexperience, and limited perspectives. When patients do visit their doctor for
a second opinion, some do not disclose the fact they already received their
first opinion and often their doctors do not ask. The result is that patients
may suffer needlessly if their fears, concerns, misunderstandings, and
misinterpretations are not addressed by the healthcare providers with the
expertise and skills to assist them. A pernicious disconnect exists between
many patients who use the Internet for health information and the medical
professionals who care for them. The medical profession can alleviate this
disconnect by taking the lead in establishing guidelines for systematically
talking to patients about, and guiding, their Internet research. Human-computer
interaction professionals can collaborate with the medical community in
ensuring credible health Web sites become the gold standard that patients use
to achieve better health.

%X Peace is an extremely important value for humankind, yet it has been largely

seeks to begin a discussion within the human-computer interaction community on
how we can design technologies that have peace as an explicit goal. To begin
this discussion, I review empirical studies on the factors that contribute to
conflict and those that make conflict less likely. Based on this, I identify
areas where human-computer interaction research has already contributed to
prevent conflict and promote peace, and open areas where our community can make
a positive difference.

%X This paper proposes a new haptic interaction system based on optical-haptic
substitution. This system combines time-modulated structured light emitted to
the workspace and a mobile or finger-mounted module consisting of a
photo-detector with a tactile actuator. Unlike other tactile feedback systems,
it does not require any complicated mechanism for position sensing and tactile
actuation. Instead, it directly converts time-modulated structured light into
haptic sensations. By sensing this light with a photo detector, users can feel
this time-modulated light as haptic sensations. The system can easily add
haptic feedback to a wide variety of applications, including surface computing
systems and 3D interactive spaces.

interactions between humans and dogs, cats, chickens, cows, hamsters, and other
species are technically possible. These efforts excite the imagination and
challenge our understanding the basic nature of computer mediated interaction.

what important social and political aspects are missing from their vision of

made.
   The parallels to human-computer interaction today are explored with two
primary intentions: -- to show how important it is that we continue to debate
and investigate the precise nature of concepts we take for granted (e.g.
usability, user interfaces, user experience), and to illustrate how practice
contributes to the development of theoretical concepts.

%X We present the Ténéré, electric power extension cords,
designed to support people's energy conservation behaviors. The focus of design
solutions was to provide appropriate energy awareness information in meaningful
and emotional ways while products are being used. A narrative of tree was used
to indicate energy use. The Tree of Tenere was the most isolated tree in the
world. The tree is dead now and replace by a tree-like sculpture. It symbolizes
the environmental consequences of human activity. When users overuse
electricity, the graphics of the tree is transformed to the sculpture. This
interactive graphics on the product encourages sustainable behaviors. Users are
expected to be impressed and change their energy behaviors. Also we verified

pursue our lives, one could question the appropriateness of functionality and
efficiency as the main guiding principles for design. User experience and
aesthetics of interaction are becoming increasingly paramount. But what makes
for aesthetic of interaction and how to design for it? In the module
"Aesthetics of Interaction" we used a variety of methods to discuss, experience
and analyse the concept of aesthetics of interaction in depth. In this extended
abstract we elucidate the methods used, i.e., movies, interaction maps,
interaction mechanisms, prototypes and silent presentations, including the
rationale behind them.

%X Eco-design has become a central research issue for interaction design, as
emerging interactive products can create serious environmental impacts while
products are being used. We investigate a design method and develop case
studies for eco-friendly interaction. A main concept of the design method is to
apply unconscious human behaviors in interaction design. Products designed with
this method are expected to be used unconsciously by users with reduced
environmental impacts. In this paper, we present a framework of design space
matrix and initial case studies for the design method. For the framework, we
identified the types of interaction behaviors causing environmental impacts and
the attributes of unconscious human behaviors. Based on the framework, three
design cases -- a power cord, a trashcan and a speedometer of an automobile --
were developed. The proposed framework and design cases can be used as a base
of an advanced eco-friendly interaction design method.

   We know that there are products that can destroy a culture. For example, the
Nazis created sophisticated products to annihilate groups of people. More
recently, many of the visually impaired have complained about not being able to
hear hybrid vehicles before crossing the street. If certain products are
destructive to a culture, can other ones enhance it?
   My hypothesis is that there are products or a class of products -- centered
around appropriate activities -- that can support an environment for people to
participate and shape. This project focuses on a specific cultural environment
and the impact a product could have in facilitating relationships and
participation in that context.

%X In this paper, we propose an immersive empathic design method and used it to
create an interactive high-resolution core visualization system for real-world
geological core drilling expeditions. A high domain knowledge barrier makes it
difficult for a person from outside this field to imagine the user experience
simply through observation. The globally distributed nature of the core
drilling community imposes further design constraints. We used this approach to
embed a computer scientist trained as a junior core technician. This process
allowed the developer to experience authentic user activities and enabled the
design of an innovative system for solving real-world problems. This approach
made the best use of precious co-located opportunities, overcame the initial
domain knowledge barrier, and established a trust relationship between the
developer and the domain scientists. The system designed through this approach
formed a sustainable and adaptive foundation that the domain scientists can
build on. Through in-situ deployment, observation and interview evaluations
from on-going expeditions, we present the advantages of this process.

and used could provide information about how designers work. We identify four
types of artful surfaces: personal, shared, project-specific and live surfaces;

%X User involvement in systems, products and related services design has
increased considerably in relevance. The way user involvement actually
progresses depends on how the users are situated in relation to the design
process. Their influence may extend from the results of the design project to
planning and managing the course of the design project. Sequential techniques
developed for the rational problem solving or reflective process have a limited
application in highly dynamic design processes. More precisely, in sequential
design processes validation steers reflection into a single direction. For this
reason, a methodological approach not based on the sequential
(hypothetical-deductive) paradigm but on the dialectical inquiry (inductive
paradigm) between designers and users is considered. The versatile and holistic
nature of this co-reflective process makes it suitable for dynamic and
unstructured design processes based on different streams of reflection.

the mouse enabled a richer design ecosystem with two dimensional plains of UI.
Now the Design and Research communities have access to multi-touch and gestural

design and develop new, unique, and richer design patterns and approaches.
These methods are no longer confined to research projects or innovation labs,
but are now offered on a large scale to millions of consumers. With these new
interface behaviors, in combination with multiple types of hardware devices
that can affect the interface, there are new problems and patterns that have
increased the complexity of designing interfaces.

%X Ethical standards for human subjects research have not kept up with new
research paradigms. Several research areas are particularly problematic for the
CHI community. Online social research is testing the boundaries of public
observation, third-party disclosure, and anonymization methods. Furthermore,
there are differences in norms about what is and is not ethical among various
research disciplines studying the Web. This SIG brings together members of the
CHI community who are interested in research ethics for studying the Web. We
invite seasoned veterans from industry and academia, educators, and newcomers
to the field to share their experiences and advice, ask questions, and to form
an interest group that can help shape university and corporate best practices
for online research.

%X Programmers of all types from novice end-user developers to professional
software engineers make use of application programming interfaces (API) within
their various designs. And, while the use of these interfaces is ubiquitous,
there is little research about their design. Recently, a number of researchers
and practitioners have begun to treat API design as a first-order object of
study and practice. The purpose of this special interest group meeting is to
bring together the community of usability researchers and professionals
interested in API usability. The time will be used to discuss attendees' ideas
and opinions in order to stimulate this new and exciting emerging field that
crosses the boundaries between human-computer interaction and software
engineering.

%X College students are primarily concerned with the price and convenience of
the food they choose to eat. Environmental impact is not a consideration in
their food decisions. We present a web-based solution that simplifies meal
choices and addresses the perception that home-prepared meals are inconvenient
and expensive. The solution provides a web service that suggests convenient
recipes that use local and seasonal ingredients tailored to the user's
location. This promotes sustainable food purchasing habits. The solution uses a
location-aware mobile device as an example platform. The study presents the
participatory design process that informed the development of this solution.

%X We designed a system of online classified ads that facilitates cascading
used Information Technology (IT) equipment such as computers, printers, and
monitors from computing-intensive labs in higher education institutions to
lower-end labs and then to administrative sites within the institution and
finally the local community. After ethnographic research and a literature
review, we found that IT departments in higher education institutions tend to
recycle instead of reuse IT equipment largely because there is no system in
place that fosters equipment reuse. In the University of Michigan, this results
in 50 tons of electronics being recycled annually, an estimated 40% of which
could be re-used either elsewhere in the institution or in the wider local
community. eXtend will promote decreased consumption of new equipment which
will lead to a decrease in the generation of local e-waste.

large display and individual kiosks that aims to increase the demand of local
produce. In cities like Detroit, where poverty and health are major concerns,
increasing consumption of local produce can help create local jobs, sustain the
environment, and improve health. We used rapid contextual design to analyze
Detroit's existing food system and, based on our findings, iteratively design a
solution. MIFresh uses proven techniques such as coupons and rewards points
programs and delivers education and awareness about the importance of consuming
local produce. User testing results among the target population are promising.

%X Increasing the reuse of locally available consumer goods is one way to make
consumption more sustainable. We present TreasureHunter, a system to help
consumers find and share used goods available at thrift stores in their local
area. TreasureHunter enlists frequent thrift store shoppers to help find
requested items for those who lack the time or inclination to search for the
items themselves. Incentive-centered design was used to craft a solution to fit
the needs of all types of shoppers. TreasureHunter consists of an online
community that is also accessible from mobile phones so that it can be used
while at a thrift store. The proposed system works best on smartphones, though
any Internet-capable phone could also be used. By motivating more people to buy
used goods instead of new, everyone can benefit as consumers pay less for the
goods they desire and fewer resources are wasted in the transportation and
consumption of new goods.

%X Commercial businesses represent a large portion of all waste generation;
furthermore, their waste streams are large and consistent enough to provide a
steady resource to other organizations that can use the waste as inputs for
their own processes. However, businesses find it difficult to connect with
other organizations, especially those in different industries. We conducted a
user-centered design process in which we interviewed 17 local organizations,
built an affinity diagram, and devised personas and scenarios. Using this
information, we designed a social network, WantKnot, which allows businesses to
find other local organizations interested in absorbing some of their waste
streams. Based on a preliminary round of usability testing, we found that
WantKnot connects businesses in valuable ways, and in doing so, reduces waste
and transportation resources.

encourages them to reduce consumption. Our solution is an application for the
Apple iPhone and iPod touch that receives data from a wireless hub, allowing
users to view, compare and analyze their electricity usage over time.

%X An increased concern for the environment has brought about an arena to
develop and experiment with new devices to support sustainable design. The
'Weigh Your Waste' (WYW) device will allow the user to monitor their waste
charges and provide a platform for the user to learn and explore areas such as:
recycling, reusing old items, how to make compost and many other green
activities. Some districts are encouraged to recycle by paying for their waste
according to its weight. Similarly, some businesses are subject to a 'pay by
weight' scheme. The WYW system proposes to tackle issues for users in these
schemes. However, users that are not subject to these schemes can still benefit
from the device by using it as a learning tool.

competently, becoming socially proficient, and finding compelling activities.
Based on these we describe a training strategy to enable professional users of

been overlooked in the HCI literature. Instead, usability has been relied upon
as the key indicator of user experience. We developed a methodology that
combined verbal and nonverbal emotion scales. A usability study was then
conducted, in which we collected both traditional usability metrics and
emotional response data. Results indicated insignificant differences in
usability metrics but numerous significant differences between emotional
responses of users. Exploration of these emotional responses successfully
provided additional insight into the user experience.

%X Today's systems are often composed of many heterogeneous, distributed
components including computing and communications infrastructure, other
hardware devices, and system and application software. Evaluating the usability
of these systems is difficult, especially in the early stages of development
when their use cannot be observed in context. While many different evaluation
methods have been proposed for evaluating stand-alone technologies, evaluating
very large-scale integrated systems requires techniques appropriate both for
individual components, and the whole of the human-computing context being
designed. Results from the case study reported here suggest that the usability
of any individual application is highly determined by its integration with
other applications in the distributed system. Modern evaluation methods need to
account for this integration in both their perspective and the measures they
use.

%X In mid-2007, one part of the technology organization at our company decided
to develop a very large project using scrum, an agile programming methodology.
The decision to go with scrum was made from a software development perspective
and how the user experience (UX) teams doing the design work would fit into
that methodology was not clear.
   As a result, the UX teams faced many challenges and we have had to evolve
our approach to how UX teams work with development scrum teams.
   This case study details our UX teams' experiences working with scrum for the
past 18 months, describing the challenges and issues that we faced, and the
solutions that we implemented to resolve those issues. We recommend best
practices for UX teams working in scrum, particularly in a fast-paced and large
corporate environment. We hope that others can avoid the common pitfalls that
we faced in our initial adjustment to agile and scrum.

%X Passive brain-computer interfaces are designed to use brain activity as an
additional input, allowing the adaptation of the interface in real time
according to the user's mental state. While most current brain computer
interface research (BCI) is designed for direct use with disabled users, I
focus my research on passive BCIs for healthy users. The goal of my
dissertation is to employ functional near-infrared spectroscopy (fNIRS), a
non-invasive brain measurement device, to augment an interface so it uses brain
activity measures as an additional input channel. I have measured and
classified brain signals that are interesting in HCI context, such as mental
workload and difficulty level of a task. My future work will focus on creating
an interface that responds to one of those measures by adapting the interface.
By combining brain signal measured with an adaptive interface I expect to
contribute a functional passive brain-computer interface that measures and
adapts to the user's brain signal.

%X Monitoring of cognitive and physical function is central to the care of
people experiencing or at risk for various health conditions, but existing
solutions rely on intrusive methods that are inadequate for continuous
tracking. This research explores the possibility of detecting cognitive and
physical stress by monitoring keyboard interactions with the eventual goal of
detecting acute or chronic changes in cognitive and physical function.
Preliminary results indicate that it is possible to classify cognitive and
physical stress conditions relative to non-stress conditions based on keystroke
and text features with accuracy rates comparable to those currently obtained
using affective computing methods. The proposed approach is attractive because
it requires no additional hardware, is unobtrusive, is adaptable to each user,
and is very low-cost.

%X High school social groups (e.g., "jocks" and "nerds") and social media
(e.g., instant messaging and social network sites) are prominent in the lives
of high school students. Social groups affect what high school students find
acceptable doing. However, little is known about how social groups affect
students' shaping of civic and political selves, or whether social media bridge
social relationships across distant high school social groups and engender
positive spill-over effects for civic participation. This socio-technical mixed
methods study is positioned at the intersection of high school social groups,
uses of social media, and students' participation in extracurricular
activities, with particular interest in civic participation. Design
implications will be drawn from analysis of three data sets: a student
questionnaire with sociometric questions, interviews, and observations of
students' daily activities. Conceptual and methodological contributions to the
HCI literature are discussed.

information or misclosure. Using multiple methods including focus groups, a
diary study, and an experimental manipulation, this thesis seeks to catalog the
incidence of such errors, identify the interface issues associated with each
type of error, and provide design recommendations for preventing each type of

%X In a computing environment where computational artifacts come and go at
rapid pace, products become easily outdated, resulting in lack of support.
Consequently, users are constantly challenged to think about the trade-offs
between maintaining and appropriating the current product and adopting an
alternative product. This challenges us to think beyond designing individual
products to be useful, usable, aesthetic, or learnable and consider what is
necessary for sustainable and long-term use. In order to further understand
users and find potential solutions to the design challenge, I explore how users
perceive their everyday computational resources becoming outdated and in
reaction how they deal with the problem during maintenance, appropriation, and
adoption of computational resources on an ongoing fashion.

%X Computer games, often played with others, are a compelling pastime for many.
However, they have been criticized for their mouse and keyboard or gamepad
interactions, as they support a sedentary lifestyle. In contrast, a "hand
exerciser" handgrip device can help strengthen hand and forearm muscles
extensively through a simple spring mechanism. Our system "mousegrip" is an
exertion interface to control computer applications while simultaneously
exercising hand and arm muscles based on a handgrip device. We present a casual
game of pong for two distributed players who control the game with a mousegrip
each, demonstrating a low-cost approach to "exertion interactions over a
distance". By showing how easy it can be to include exertion in interactions
with computers, we hope to encourage other researchers and designers to
consider exertion activity in their designs in order to support a healthy
lifestyle.

as the Apple iPhone. However, optical systems are inherently bulky while
capacitive systems are only practical in small form factors and are limited in
their application because they only respond to human touch.
   We have created a technology that enables the creation of Inexpensive
Multi-Touch Pressure Acquisition Devices (IMPAD) which are paper-thin, flexible
and can easily scale down to fit on a portable device or scale up to cover an
entire table. These devices can sense varying levels of pressure at a
resolution high enough to sense and distinguish multiple fingertips, the tip of
a pen or pencil and other objects.
   Other potential applications include writing pads, floor mats and entry
indicators, bio-pressure sensors, musical instruments, baby monitoring,
drafting tables, reconfigurable control panels, inventory tracking, portable
electronic devices, hospital beds, construction materials, wheelchairs, sports
equipment, sports clothing and tire pressure sensing.

%X In this paper, we describe the design of menus for multi-user digital
tabletops. On direct input surfaces, occlusions created by the user's hand
decrease interaction performance with menus. The key design criteria are to
avoid these occlusions and to adapt the menu placement to the user's handedness
and position on the tabletop. We present an adaptive menu placement method
based on direct touch and pen tracking that allows correct menu placement
around the table. As an extension, we propose adding a gesture input area for
fast interaction which can be partly occluded by the user's hand.

%X We present Silicone iLluminated Active Peripherals (SLAP), a system of
tangible, transparent widgets for use on vision-based multi-touch tabletops.
SLAP Widgets are cast from silicone or made of acrylic and include sliders,
knobs, keyboards, and keypads. They add tactile feedback to multi-touch tables
and can be dynamically relabeled with rear projection. They are inexpensive,
battery-free, and untethered widgets combining the flexibility of virtual
objects with tangible affordances of physical objects. Our demonstration shows
how SLAP Widgets can augment input on multi-touch tabletops with modest
infrastructure costs.

imagination while learning about concepts in computing and technology.
   However, there are still numerous difficulties involved in deploying
existing technology in an educational environment. In this paper, we present
the TeeBoard, a construction platform for e-textiles and wearable computing
that is designed to be robust, reliable, easy to construct and to program. It
has also passed initial tests in a practical workshop for high school students.

%X Finding a specific or an artistically appropriate sound in a vast collection
comprising thousands of audio files containing recordings of, say, footsteps,
gunshots, and thunderclaps easily becomes a chore. To improve on this, we have
developed an enhanced auditory and graphical zoomable user interface that
leverages the human brain's capability to single out sounds from a spatial
mixture: The user shines a virtual flashlight onto an automatically created 2D
arrangement of icons that represent sounds. All sounds within the light cone
are played back in parallel through a surround sound system. A GPU-accelerated
visualization facilitates identifying the icons on the screen with acoustic
items in the dense cloud of sound. Test show that the user can pick the "right"
sounds more quickly and/or with more fun than with standard file-by-file
auditioning.

because gaze trackers are usually expensive (above $10.000). In this paper we
present a low-cost gaze pointer, which we have tested in combination with a
desktop monitor and a wearable display. It is not as accurate as commercial
gaze trackers, and walking while pointing with gaze on a wearable display
turned out to be particularly difficult. However, in front of a desktop monitor
it is precise enough to support communication. Supplemented with a commercial
EMG switch it offers a complete hands-free, gaze-and-click control for less
than $200.

addresses the seamless combination of sensor-enabled phones with large

or continuous interaction with both mobile applications and distant user
interfaces by utilizing the handheld as a remote control. In addition, we
introduce throwing gestures to transfer media documents and even running
interfaces to a large display. To improve usability, data and interfaces can be
thrown from a mobile phone to a distant screen and also fetched back to achieve
mobility. We demonstrate the feasibility of the interaction methods with
several advanced application prototypes facilitating a natural flow of
interaction.

into the frame and a small pocket-worn component with a powerful
microcontroller for EOG signal processing. Using this lightweight system,
sequences of eye movements, so-called eye gestures, can be efficiently
recognised from EOG signals in real-time for HCI purposes. The device is
self-contained solution and allows for seamless eye motion sensing,
context-recognition and eye-based interaction in everyday environments.

%X One of the central challenges of the User Experience discipline has always
been how early in the development cycle it can exert any degree of influence.
The challenge that our field is facing today more pronounced than ever is how
to influence the decision makers that give directions guiding individual
product development. And vice versa, this early decision making process can
benefit from user experience approaches that help ground its direction in user
research, and inform its decisions creatively through concepts and design
thinking -- see for example the concept of Business Design (as taught by the
Rotman school of management, with similar approaches being the foundation of
successes such as design consultancies like IDEO). The goal of the panel will
be to draw together a community of experts and interested audience members in
this topic and initiate a discourse on its key issues and opportunities.

%X While health records are increasingly stored electronically, we have little
access to this data about ourselves. We're not used to thinking of these
official records either as ours or as something we'd understand if we had
access to them in any case. We increasingly turn to the Web, however, to query
any ache, pain or health goal we may have before consulting with health care
professionals. Likewise, for proactive health care, such as nutrition or
fitness, or post diagnosis support, to find fellow-sufferers, we turn to online
resources. There is, it seems, a potential disconnect between points at which
professional and proactive health care intersect. Such gaps in information
sharing may have direct impact on practices we decide to take up, the care we
seek, and the support professionals offer. In this panel, we consider several
places within proactive, preventative health care in particular HCI has a role
towards enhancing health knowledge discovery and health support interaction.
Our goal is to demonstrate how now is the time for eHealth to come to the
forefront of the HCI research agenda.

qualitative feedback on the prototype from 15 physicians. The physicians found
activeNotes to be valuable and said they would use it to create both formal
notes for medical records and informal notes. One surprising finding is that
while physicians have rejected template-based clinical documentation systems in
the past, they expressed a desire to use activeNotes to create personalized,
physician-specific note templates to be reused with a given patient, or for a
given condition.

Lock, two techniques that support the selection of moving targets. Our goal is
to facilitate accurate and fast selection of moving targets. We compare our two
techniques to unassisted selection in a controlled experiment. The results show
that for moving target selection, Comet Tails and Target Lock can outperform
unassisted selection, and result in fewer errors. According to post-experiment
questionnaires, participants indicate a stronger preference for assisted target

differently according to acoustic features and to perceptual dimensions.
Acoustic features fail to characterize the perceptual dimension of valence.
More research is needed to find acoustic features that have a close relation to
human perception.

%X More than 60% of the Indian population resides in rural areas with
agriculture as the main profession. Although small scale rural Indian farmers
possess deep knowledge about traditional agricultural practices, they
oftentimes lack immediate, contextual and real time access to vital information
such as the current state of the agro-market, making the right choice of
pesticides and fungicides for pest management, weather conditions, and
knowledge about newly introduced agricultural tools, techniques and practices.
In this paper, I report the preliminary findings of an ongoing contextual user
research study conducted in three different Indian villages in Maharashtra
State. This research is targeted to uncover a deeper understanding of the
information needs of Indian rural farmers through field observations and
interviews, as well as to guide the human-centered design of potential
Information and Communication Technology (ICT) solutions to cater to the
information needs of small scale rural farmers in India.

%X We studied how spatial locations and luminance affect finding and re-finding
information in a desktop environment. In an experiment conducted with computer
icons, fixed locations led to more frequent accesses to icons while change of
luminance led to worse recall of icon titles and locations. Results are
consistent with the notion that information search behavior is adaptive to the
cost-benefit structure of the interface, and search strategies are adaptive to
different external representations of icons. Results also suggest that both
external representations and human information processes are critical in
determining the effectiveness of different GUI designs.

%X Reading fiction is many people's favorite pastime. There is no denying that
one of the needs of human beings is to share what they read and understand
other readers' feelings about the books they have read. Recent developments in
Web 2.0 technologies characterizing personalized information organization have
led to an interest in social tagging behavior of a variety of items, such as
books, images, web pages, videos, etc. However, a major issue with this kind of
application is that tags are growing in an uncontrolled manner. In fact, it is
chaos. Several studies have recognized the existence of affective tags, but
there is no user interface designed to separate affective tags from other tags.
To address that affective tags are navigation aids for readers, this work gives
an account of design of a novel interface for visualization of affective tags
at a social cataloging website, LibraryThing.com.

icon shape affectively. A model to project arbitrary music on the plane is
introduced using the result of a user survey and various features of audio
signals. Icon shapes are located on the plane from the result of user survey.
The icon shape of the input music is obtained by blending neighbor icon shapes
of the point of the music on the emotion plane. Using this method, one can
easily guess the emotion of music from the corresponding icon shape and find
the music he or she wants.

and they then performed a search task and finished a series of questionnaires.
Our findings supported affect-as-information: the comparatively happy
participants were inclined to process more general and less specific
information; the comparatively sad participants were likely to process more
specific information. The findings advances theoretical and empirical
understanding concerning the characteristics of users' information seeking
behavior under different moods. Our study will contribute to affective search
systems design.

and appliances such as doors, sofas, refrigerators and televisions with
sensors, we developed a system where these items are connected to remote
equivalents and their near simultaneous use is communicated.

%X In the last few years, accelerometer-based entertainment and health
applications have been receiving increased attention in the research and
commercial worlds. The effect of accelerometer placement on different parts of
the body, despite its apparent significance, received little consideration.
This paper documents through experimentation the different characteristics of
accelerometer output on the waist, arm, wrist, thigh, and ankle in the context
of translational body motion (walk). Furthermore, it offers experimental
formulas that transform peripheral body measurements to more reliable, center
body (i.e., waist) measurements, and these in turn to caloric measurements,
which are the standard physical activity units. The importance of these results
on the design of ubiquitous health applications and the ensuing user
experiences cannot be underestimated. The paper's methodology can be used in
further studies in other physical activity contexts, where more elaborate body
motion patterns are involved.

%X Knowledge workers increasingly use multiple devices such as desktop
computers, laptops, cell phones, and PDAs for personal information management
(PIM) tasks. The use of several of these devices together creates higher task
difficulty for users than when used individually (as reported in a recent
survey we conducted). Prompted by this, we are conducting an experiment to
study mental workload in multi-device scenarios. While mental workload has been
shown to decrease at sub-task boundaries, it has not been studied if this still
holds for sub-tasks performed on different devices. We hypothesize that the
level of support provided by the system for task migration affects mental
workload. Mental workload measurements can enable designers to isolate critical
sub-tasks and redesign or optimize the user experience selectively. In
addition, we believe that mental workload shows promise as a cross-tool,
cross-task method of evaluating PIM tools, services and strategies, thus
fulfilling a need expressed by several researchers in the area of personal
information management. In this paper, we describe our ongoing experiment of
measuring mental workload (via physiological as well as subjective measures)
and its implications for users, designers and researchers in PIM.

a complex task. An initial instruction is required even if they do their tasks
autonomously. We therefore need interfaces for the operation and teaching of

used for this purpose. These interfaces, however, have difficulty in operating
multiple robots simultaneously. We developed a multi-touch interface with a
top-down view from a ceiling camera for controlling multiple mobile robots. The
user specifies a vector field followed by all robots on the view. This paper
describes the user interface and its implementation, and future work of the
project.

this difficulty, we developed a content stabilization technique, called
""ReadingMate,"" using head-tracking to track the location of the jogger's
head/eyes and relocate the position of the contents on a screen, so that the
contents appear to be stabilized. We conducted an experiment with ten
participants, and eight out of ten reported positive experiences in using
ReadingMate. Thus, ReadingMate could be a potential solution for joggers who
would like to read while running, and possible future work is also discussed.

   This study examined how users' web search and browsing behavior differs when
the connection is slow, and whether users employ techniques to alleviate the
problem. In a preliminary study involving 15 subjects on a university campus in
Kerala, India, we identify unique mitigating behaviors of users who routinely
suffer low-bandwidth or intermittent connections. We examine the challenges
faced by these users and find that existing web search and browsing
infrastructure is simply incapable of providing a good experience. Finally we
outline potential design improvements.

%X VJing is a live performance of visual media. In their performances VJs
utilize technologies in ways which subvert and evolve current interfaces;
presenting qualities such as performativeness and expression. By developing
interfaces in direct response to a VJ's work, we can learn how to develop fresh
styles of interaction. The subtle nuances of a VJ's use of technology may not
be achieved through a simple observation or dialogue with VJs; as they are
difficult to decouple from the performer's creative process.
   In this film we present a design process that utilizes video documentary to
explore the working practices of a collection of VJs. The documentary frames
our engagement with the creative processes which shape an individual artist's
performance. We describe the process detailing the initial creation of the
documentary, and a participatory design workshop inspired by the film. We
conclude with an example of how the process has been used in the design of a
personal interactive tool for one of our participants.

%X Mobile devices have changed, and continue to shape, the world in which we
live. When these devices were first introduced they were most often used in
isolation to schedule appointments, take notes, play games, or view or edit
pictures and stories. The extent of the collaboration on these mobile devices
was to make phone calls, which has led to their worldwide distribution. Despite
their broad proliferation, there are limitations such as small screen size and
limited interaction space. We believe that by bringing devices and people
together, these limitations can be overcome. In this video submission, we
illustrate the potential of devices and people working together by showing how
children can collaboratively read and create stories using mobile devices and
exploit the shoulder-to-shoulder collaborative situation to share and expand

servers, coordination, or administration. A key feature of this platform is the
fact that it combines knowledge, awareness, and learning of the user's social
relationships and integrates this information into the communication protocols
and network services. Comm.unity is designed to work on as many devices as
possible, and with as many different radios as possible (WiFi, Bluetooth, IR,
etc.). It is designed as a platform over which many different networked
applications could be developed with ease, from the bottom layers of the
network all the way up to the user interface. In this short movie we present
some use cases for Comm.unity based applications, including the "Social

Stick-Anywhere Computer was implemented using a Xuuk Eyebox2 IR camera that
tracks nearly invisible IR markers on post-it notes as well as fingers, and
uses a projector to render interactive content directly onto the paper note.

%X The canon is a composition pattern with a long history and many forms. The
concept of the canon has also been applied to experimental film making and on
Japanese television. We describe our Interactive Visual Canon Platform (IVCP)
that enables creators of visual canons to design their movements through rapid
cycles of performance and evaluation. The IVCP system provides real time
support for the actors; they can see the canon resulting from their movements
while they are still performing. We describe some possible approaches to a
solution, and reasons for choosing the approach that we have implemented. The
hardware has reached a stable state, but we are still optimizing the visual
processing of the system. A first user test is planned to provide us with
information for improving the system.

a video scene. The slit-tear visualization technique is a generalization of the
traditional photographic slit-scanning and more recent video slicing
techniques: after a user specifies a pixel path of interest, the system
generates a timeline that replicates those pixels for each frame in the video.
These rich visualizations of the video data help users to discover and explore
spatio-temporal patterns of activity in a video. In this video, we illustrate
the use of slit-tear visualizations to detect movement and incidence of
activity in a video scene, accentuate directional motion and small changes in
the video, and discover patterns of activity between spatially distinct areas
of the scene.

%X Film is an accessible medium that can be used naturally to elicit comment
and critique. In this sense film can be as the natural language for experience
design. We are developing a series of experimental films that can convey
user-experience without explicitly depicting the object that generates that
experience. In doing this, we are building upon the idea (well rehearsed in the
scientific debate about mental imagery) that some visual representations can be
inexplicitly non-committal about the presence or absence of certain objects or
features. Our films are explicitly non-committal about the objects they
describe -- in the sense that the devices are deliberately kept hidden or
invisible to the user. We present one such film that captures a security device
we call a Biometric Daemon -- essentially an electronic pet that thrives on
biometric signals. Crucially, the Daemon is never shown in the film, while the
relationship between the Daemon and the user is made apparent.

%X Today, mobile phones are no longer devices supporting only voice
communications. Many people use their mobile phones as multimedia players,
cameras, messaging systems, etc. Therefore, it is required to design a user
interface that improves the usability of multi-functional mobile phones. For
this purpose, we proposed a novel user interface that utilizes touch sensing
technology to support multi-functional devices. The proposed user interface is
based on the assumption that the device can detect how a user holds the device.
By analyzing the user's grip-pattern, the device recognizes the user's
intention and adjusts itself to meet the specific needs of the user such as
accessing an application. The concept of the user interface is presented
through several use-case scenarios. In addition, the technical feasibility of
the proposed interface is validated by implementing a working prototype system.

%X Exertion games -- games that require physical effort from the user -- have
been attributed with many social, mental and in particular physical health
benefits. However, research has shown that most current implementations support
only light or moderate exercise. We are presenting "Remote Impact --
Shadowboxing over a Distance", in which players punch and kick a life-size
shadow of a remote participant in order to win the game. The game includes a
novel multi-touch large-scale interaction surface that is soft (so no-one gets
hurt), but can detect the location as well as the intensity of the players'
even most extreme impacts. Remote Impact shows that computer-augmented games
can support extreme exertion while supporting novel experiences, such as a
reduced risk of injury and supporting distant players, offering a new way of
thinking in which areas Human-Computer Interaction research can contribute to
our lives.

%X Within the home, digital photos lack the physical affordances that make
collocated photo-sharing easy and opportunistic. Family members have difficulty
accessing the personal accounts of the photo organizer, navigating to these
photos, or finding the desired ones within the vast number of photos stored on
disk. Viewing photos on a standard PC screen is also awkward due to crowding.
To promote in-home photo sharing, we designed Souvenirs, an RFID-based system
that lets people quickly link digital photo sets to physical memorabilia. These
memorabilia trigger memories and serve as social instruments; a person can
enrich their story-telling by moving the physical memorabilia close to their
large-format television screen, and the associated photos are immediately
displayed. A person can also bring a mobile device near memorabilia: the photos
appear on that display. Through pick and drop, a person can also transfer the
photo display from the mobile device to the large screen for easier viewing.
This video motivates and illustrates how all this works.

%X In this paper we describe a method to enable a robot to learn how a user
gives commands and feedback to it by speech, prosody and touch. We propose a
biologically inspired approach based on human associative learning. In the
first stage, which corresponds to the stimulus encoding in natural learning, we
use unsupervised training of HMMs to model the incoming stimuli. In the second
stage, the associative learning, these models are associated with a meaning
using an implementation of classical conditioning. Top-down processing is
applied to take into account the context as a bias for the stimulus encoding.
In an experimental study we evaluated the learning of user feedback with our
learning method using special training tasks, which allow the robot to explore
and provoke situated feedback from the user. In this first study, the robot
learned to discriminate between positive and negative feedback with an average
accuracy of 95.97%.

%X Understanding other people's goals is an essential part of interpersonal
interactions. This capability enables a person to naturally predict another
person's future actions in a situation and produce appropriate joint or shared
actions. In like manner, a human-like planning agent (or sociable robot) should
be able to understand the user's action goal and come up with subgoal-based
plans to achieve the goal. In this paper we focus on how the agent can
automatically construct the subgoal-based action hierarchy corresponding to the
user's high-level goal. As a first step, we implement an action-planning engine
based on ConceptNet, and indicate the drawbacks of using ConceptNet for this
purpose. Also, we present the structure of a new goal-oriented
commonsense-reasoning knowledgebase for the agent's action-goal representation
and action planning.

%X This paper presents on-going work in developing service robots that provide
assisted-care to the elderly in multi-party settings. In typical Japanese
day-care facilities, multiple caregivers and visitors are co-present in the
same room and any caregiver may provide assistance to any visitor. In order to
effectively work in such settings, a robot should behave in a way that a person
who has a request can easily initiate communication with the robot. Based on
findings from observations at several day-care facilities, we have developed a
robot system that displays availability to multiple persons and then displays
recipiency to an individual person who wants to initiate interaction. Our robot
system and its experimental evaluation are detailed in this paper.

automatically summarizes players' actions and interactions in the virtual
world. The feature of the system is that it analyzes the log and screenshots of
a game, decides which events are important and memorable, and then generates
comics in a fully automatic manner. Also, the interface of our system allows
users to customize their own comics. As a result, users can easily use the
system to share their stories and create individual comics for archival
purposes or storytelling.

that allows users to intuitively establish virtual boundaries in indoor
environments. Boundaries can be easily created/modified by arranging the
layouts of disk-shaped devices ("stones") on the building floor. The immediate
purpose of the system is to assist users in incorporating location-aware
capabilities into private properties, esp. individual households and offices,
with the longer-term goal of serving as a key component in our vision of
"Synthetic Space" -- architectural space of the future where all building
elements (walls, windows, etc.) can be dynamically reconfigured in real time.

%X For the majority of blind people, walking in unknown places is a very
difficult, or even impossible, task to perform, when without help. The adoption
of the white cane is the main aid to a blind user's mobility. However, the
major difficulties arise in the orientation task. The lack of reference points
and the inability to access visual cues are its main causes. We aim to overcome
this issue allowing users to walk through unknown places, by receiving a
familiar and easily understandable feedback. Our preliminary contributions are
in understanding, through user studies, how blind users explore an unknown
place, their difficulties, capabilities and needs. We also analyzed how these
users create their own mental maps, verbalize a route and communicate with each
other. Structuring and generalizing this information, we were able to create a
prototype that generates familiar and adequate instructions, behaving like a
blind companion, one with similar capabilities that understands his "friend"
and speaks the same language. We evaluated the system with the target
population, validating our approach and orientation guidelines, while gathering
overall user satisfaction.

vibration, as well passive haptic feedback, using shape and firmness. An
initial experiment demonstrated that users could reliably discriminate among
the three firmness levels displayed on our prototype.

%X This paper presents a calibration-free method for estimating the point of
gaze (POG) on a display by using two pairs of stereo cameras. By using one pair
of cameras and two light sources, the optical axis of the eye and the position
of the center of the cornea can be estimated. This estimation is carried out by
using a spherical model of the cornea. One pair of cameras is used for the
estimation of the optical axis of the left eye, and the other pair is used for
the estimation of the optical axis of the right eye. The point of intersection
of optical axis with the display is termed the point of the optical axis (POA).
The POG is approximately estimated as the midpoint of the line joining POAs of
both the eyes with the display. We have developed a prototype system based on
this method and demonstrated that the midpoint of POAs was closer to the
fiducial point that the user gazed at than each POA.

%X Alternative Reality Games (ARGs) provide an interesting platform to explore
the nature of game play as they combine fictional and real world elements to
create a unique gaming experience. A typical ARG plays over a set time span and
players collaborate via an ongoing narrative orchestrated by 'puppet masters'.
This paper presents a six week study based around an ARG which was designed to
be repeatable, allowing players to enter the game at anytime. Through the use
of temporal trajectories we analyse player's interactions and unveil a number
of problems that hindered game play. The players lifestyle, pace and gameplay
traits all impacted on the game and raises the question of whether a repeatable
ARG can really work. We close with some design pointers that might make it
feasible.

a scenario which is symmetric to a traditional human-initiated interaction. We
report on an initial qualitative study focusing on the opposite type of

that request interactive dialog from the recipients. The study consisted of 16
telephone calls to participants placed by a simulated agent, followed by
debriefing interviews with the participants. The data gained in the study were
analyzed to identify factors that influence the acceptance of such calls.

%X People with dementia have problems carrying out multi-step tasks such as
making a hot drink. Intelligent systems are being built to prompt people
through such tasks. However, the prompts used by these systems are likely to be
viewed as novel. As people with dementia are known to be sensitive to novelty
this could be a problem. An experiment was performed to determine how to prompt
people with dementia with which knob controls which burner on a cooking range.
A highly novel implicit attentional cue using fluorescent wire was found to
provide comparable or better results than more conventional alternatives. It is
concluded that design in this area does not need to be constrained by the need
to avoid novelty. The experiment is also of interest because of the way that it
was embedded in a natural cooking task suitable for people of varied cognitive
capacity.

Space suggests a new way to connect remote spaces with sensor data in
Telecommunication Art and also suggests ways to enable users to understand
quantified data with interaction in a more concrete way.

short distance with which it requires physically contacting them together,
which we call Contact-and-Connect Interface. Through prototyping, we examined
the usability of this new interface, and as a result, we realized that all of
the participants recognized the pairing easily due to the following three
factors: contact action, LED visualization of connection, and instant feedback
of what is happening. We also figured out which external forms have better
affordance for the contact action, and the ones having no sharp edges with a
perfect fit worked best.

%X The vision of Ubiquitous Computing is a world of invisible technologies.
Technologies are so woven into the fabric of everyday life that they become
indistinguishable [1]. In this paper, we discuss unobtrusive interfaces having
minimal presence. By merging into everyday objects and environments, the
presence of an interface can be minimized, making our everyday life more
interactive without increasing its complexity. To obtain minimal presence,
physical plasticity of the interface is considered in the present work. This
allows the interface to shift between invisible and visible states; the
concealed interface appears when it is put into use and disappears after use.
In addition, our recent project, Shade Pixel, is presented as an example of an
unobtrusive interface with minimal presence. We also briefly describe a design
concept for the interface to provide inspiration for its practical application.

is a central design target for interactive products and services. Increasingly,
Web services are developed for both PCs and mobile terminals to support user
needs for media content management and social interaction. Even though many UX
models have been developed over the last decade, the specific characteristics
affecting UX of Web services have not been studied systematically. In this
paper we present the first phase of our service UX study in which three Web
services were evaluated by three UX experts each, using an initial set of
service UX evaluation heuristics. We discuss how well these heuristics covered
the positive and negative service UX evaluation findings, and how the
heuristics and the expert evaluation approach of UX should be developed
further.

%X Early in Tod Machover's opera Death and the Powers, the main character,
Simon Powers, is subsumed into a technological environment of his own creation.
The theatrical set comes alive in the form of robotic, visual, and sonic
elements that allow the actor to extend his range and influence across the
stage in unique and dynamic ways. This environment must compellingly assume the
behavior and expression of the absent Simon. In order to distill the essence of
this character, we recover performance parameters in real time from
physiological sensors, voice, and vision systems. These gesture and performance
parameters are then mapped to a visual language that incorporates cognitive and
semantic models informed by modal relationships. This language allows the
off-stage actor to express emotion and interact with others on stage. Our
Disembodied Performance system takes a new direction in augmented performance
by employing a non-representational abstraction of a human presence that fully
translates a character into an environment.

displays were useful when applied to domestic messaging. We performed an
ethnographic study with two different types of households, during which we
analysed their usage of the system and conducted a series of interviews. We
found that all households used the system to some degree, but that the social
context and communication styles were distinctly different between households
comprised of families and those with fictive kin. This highlights the
importance of considering the household structure when designing domestic
technology. Additionally, our preliminary study explored the minimum
requirements for a useful messaging appliance for the home, particularly with
respect to interactivity.

%X In recent navigation HCI studies, the shift from investigating map-based
mobile applications towards supporting mobile users' wayfinding tasks with
multimodal navigation aids is apparent. While there have been many studies of
navigation design guidelines for using maps or speech- or tactile-based
guidance in mobile devices, in this paper we propose an initial study of
multimodal navigation design utilising the theory of designing episodes of
motion originating from urban planning. The implications of designing cues and
providing rhythm, as the theory of episodes of motions suggests, are explored,
with pedestrians as the subjects using wayfinding tasks in an urban area. The
main contributions of this paper are in investigating the design principles,
evaluating them in the context of mobile wayfinding tasks, and reflecting upon
the results in terms of users' wayfinding behaviour. It is concluded that by
designing predictive clues and rhythm into mobile multimodal navigation
applications, we can improve navigation aids for users.

%X This paper investigates if and how a digital, interactive affective mirror
induces positive emotions in participants. We study whether the induced affect
is repeatable after a fixed interval (Study 1) and how the social presence
affects the emotion induction (Study 2). Results show that participants
systematically feel more positive after an affective mirror session; this
effect is shown to be repeatable, and co-presence of a friend is shown to boost
this effect.

%X Prior work has shown that goal crossing may be a more accessible interaction
technique than conventional pointing-and-clicking for motor-impaired users.
Although goal crossing with pen-based input devices has been studied, pen-based
designs have limited applicability on the desktop because the pen can "fly in,"
cross, and "fly out," whereas a persistent mouse cursor cannot. We therefore
explore possible designs for accessible mouse-based goal crossing widgets that
avoid triggering unwanted goals by using secondary goals, gestures, and corners
and edges. We identify four design principles for accessible desktop goal
crossing widgets: ease of use for motor-impaired users, safety from false
selections, efficiency, and scalability.

%X We developed a system which performs 3D motion tracking of human's hand and
fingers from images of a single high-frame-rate camera and that recognizes
his/her typing motion in the air. Our template-matching-based method using hand
textures reduces background effect and enables markerless tracking. In
addition, use of a high-frame-rate camera enables recognition of rapid typing
motion which is difficult to track using standard cameras. In order to realize
real-time recognition, we developed hardware which parallelizes and accelerates
image processing. As a result, we achieved real-time recognition of typing
motion with the throughput of 138 fps (frames per second) and the latency of 29
ms.

exploring the possibility of incorporating tagging into the hierarchical folder
structure for file management, especially for the process of file organization
and file re-finding. This work will provide design implications for future file

%X In this paper, we describe a virtual game where game play is afforded by the
user's silhouette interacting with on-screen 3D gaming objects, e.g. a soccer
ball or a "chapteh" (Shuttlecock Kicking) -- a game played traditionally in
villages, i.e. "kampongs", in Asia. The virtual game system projects a
life-size image of the location where the game is often played, e.g. soccer
field when soccer is played or village playground in the case of "chapteh". The
player's silhouette is super-imposed on the screen as the user interacts with
the on-screen virtual 3D object using his body movement, e.g. bounce or lift.
We compare the game play when different design variables were changed, e.g.
replacing the soccer field image or removing the silhouette outline, to
evaluate which design variable affects a user's experience during game play.

people interact with maps. Map use research has often focused on higher order
use goals or cognitive interpretations of static map representations. In order
to address the problem of understanding foundational user-map interaction

an initial focus on analysis tasks. This paper describes an exploratory user
study to examine general interaction issues with complex map visualizations.
Our results highlight the need for map tools to improve interactivity and

results show that (i) the occupation and background (persona) of the robot help

%X Audio is a key feedback mechanism in eyes-free and mobile computer
interaction. Spatial audio, which allows us to localize a sound source in a 3D
space, can offer a means of altering focus between audio streams as well as
increasing the richness and differentiation of audio cues. However, the
implementation of spatial audio on mobile phones is a recent development.
Therefore, a calibration of this new technology is a requirement for any
further spatial audio research. In this paper we report an evaluation of the
spatial audio capabilities supported on a Nokia N95 8GB mobile phone.
Participants were able to significantly discriminate between five audio sources
on the frontal horizontal plane. Results also highlighted possible subject
variation caused by earedness and handedness. We then introduce the concept of
audio minimization and describe work in progress using the Nokia N95's 3D audio
capability to implement and evaluate audio minimization in an eyes-free mobile
environment.

Augmented Reality (AR) in the last few years. Traditional paper-based maps
provide high-resolution, large-scale information with zero power consumption.
There are numerous implementations of magic lens interfaces that combine
high-resolution paper maps with dynamic handheld displays. From an HCI
perspective, the main challenge of magic lens interfaces is that users have to
switch their attention between the magic lens and the information in the
background. In this paper, we attempt to overcome this problem by using a
lightweight mobile camera projector unit to augment the paper map directly with
additional information. The "Map Torchlight" is tracked over a paper map and
can precisely highlight points of interest, streets, and areas to give
directions or other guidance for interacting with the map.

factors that determine the language multilingual searchers choose to search in,
if they switch languages within a search task, and if they encounter challenges
when searching in a non-native language. Our results indicate that availability
and perceived quality of information were the primary reasons for searching in
a non-native language. Language switching within a search only occurred when
information could not be found with the original search language. We also
observed a language-related use case where the goal was not to find information
in a typical sense, but rather to check for correct phrases in the non-native
language using search engines. Our research highlights several areas of future
work for further understanding the multilingual search process.

participants, and compared the result with an existing commercial SPT
(Single-Point Touch) input method. The experimental results show that the entry
speed of MPT was slower than that of SPT method in the initial session.
However, the entry speed of MPT input method was improved more rapidly than the
speed of SPT method as sessions were proceeded. We observed a statistically
significant learning effect from the result of MPT method. Moreover, we found
no significant difference between the task loads of SPT and MPT input methods.

preceding actions, and predicts the intention just when the actual action
starts. This paper tests P-Recognition in a pen-based map navigation interface
as an example, where the map is panned by user's dragging strokes and zoomed by
user's enclosure by a circle. The feasibility of the proposal is confirmed in
an experiment. We find that dragging and circling actions are distinguishable
before the pen touches the screen. Moreover, for some users we can recognize
their intention to write text. It is confirmed that the user's intention is
present in the preceding actions and so is detectable.

the query reformulation patterns for 964,780 Web searching sessions (composed
of 1,523,072 queries) in order to predict what the next query reformulation
would be. We employed an n-gram modeling approach to describe the probability
of searchers transitioning from one query reformulation state to another and
predict their next state. We developed first, second, third, and fourth order
models and evaluated each model for accuracy of prediction. Findings show that
Reformulation and Assistance account for approximately 45 percent of all query
reformulations. Searchers seem to seek system searching assistant early in the
session or after a content change. The results of our evaluations show that the
first and second order models provided the best predictability, between 28 and
40 percent overall, and higher than 70 percent for some patterns. Implications
are that the n-gram approach can be used for improving searching systems and
searching assistance in real time.

Product Interest and Engagement Scale (PIES), a short assessment instrument
measuring consumer interest in technology products. PIES reflects an explicitly
multidimensional, hierarchical, and extensible model of product interest. It
assesses consumer product interest in terms of an overall interest scale plus
three subscales assessing interest in features and choices, personal image as
affected by a product, and interest in optimizing one's choice with regards to
a product. We report factor structure in a sample of N=225 US consumers and
replication with N=180 US consumers. The results establish reliability of the
overall 12-item scale and subscales in a broad consumer sample (Cronbach's
alpha = 0.89 overall, 0.82-0.88 for subscales). Validity measures in the
validation sample demonstrate convergent and discriminant validity with product
ownership and product involvement measures. We regard PIES as currently being
in beta form (PIES-beta). It is suitable for usage now but will undergo further
revision in 2009.

backside of a handheld device provides button-edge and button-push feelings to
the fingertip(s) that hold the device. Preliminary evaluations indicate that
proposed techniques improve "usability" and "preference" without deteriorating

a stroke. The purpose of the application is to make the rehabilitation of
handwriting skills fun and engaging. Four platform-independent games with
adjustable levels of difficulty were created in order to target varying levels
of skills. The application also features a performance history, audio-visual
feedback, and posture reminders. It was evaluated with medical staff and
patients from the Hoensbroeck Rehabilitation Centre in the Netherlands. The
initial results indicated that the games are more motivating and fun than
traditional pen and paper exercises. The feedback received from therapists
supports our claim that the games are a useful addition to the rehabilitation
of handwriting.

%X The ESP Game was designed to harvest human intelligence to assign labels to
images -- a task which is still difficult for even the most advanced systems in
image processing. However, the ESP Game as it is currently implemented
encourages players to assign "obvious" labels, which can be easily predicted
given previously assigned labels.
   We present a language model which can assign probabilities to the next label
to be added. This model is then used in a program, which plays the ESP game
without looking at the image. Even without any use of the actual image, the
program manages to agree with the randomly assigned human partner on a label
for 69% of all images, and for 81% of images which have at least one
"off-limits" term assigned to them.
   We discuss how the scoring system and the design of the ESP game can be
improved to encourage users to add less predictable labels, thereby improving
the quality of the collected information.

%X The use of computers in the workplace is now commonplace. Correspondingly,
injuries associated with computer use have increased. However, little research
has been done investigating whether these injuries are associated with the
software being used. One reason is the difficulty in measuring muscle strain (a
predictor of muscle related injuries). Here we present preliminary results of
study on the relationship between objective and subjective measures of muscle
strain during computer use. As users completed sets of tasks using MSWord, SEMG
muscle activity was recorded for the muscles associated with using a keyboard
and mouse. After each task set, users completed surveys asking the level of
strain they experienced during the tasks. Correlations between the measures
suggest that subjective measures can provide reliable information regarding the
muscle strain associated with software use. These easily obtained subjective
measurements could assist in producing software interaction designs that are
better for users.

%X With the growing volume of digital information users must deal with,
management and retrieval tasks have become increasingly problematic. A popular
way to help users organize their information is tagging, as is the case in web
sites such as flickr, delicious or youtube. Unlike traditional
hierarchically-based organization principles, tagging is less strict and easier
to employ. However, it is not without its own problems. Low tag reuse is just
one of several issues that might hinder retrieval of a document or photo at a
later time. We propose that narratives can provide a better way of tagging
photos. Describing a photo by telling a story about it may yield more and
better tags, as information in stories is organized as a structured, coherent
whole. We present a prototype web application, StoryTags, that allows users to
tell stories to tag their photos, and then to use those stories to retrieve
them.

%X Decisions about what to eat are often made close to mealtime, when hunger
clouds people's ability to think creatively or conscientiously about their meal
choices. As a result, people we studied tended to resort to "everyday meals":
recipes that are tasty, quick, and cheap. These choices often run counter to
cooks' stated values regarding health, variety, ingredient choice, and so
forth, but are chosen for their convenience and familiarity. This lack of
variety seemed to stem from a scarcity of "everyday" recipes compounded by the
fact that usually, at the time they are preparing the meal, cooks are tired,
hungry, and don't want to search for or try less familiar recipes. Based on a
study of current cooking practices, we developed the SuChef prototype: a
low-fidelity probe supporting the in-kitchen display of everyday meal ideas
along with the sharing of recipes among members of social groups. The probe was
deployed for a week among 5 geographically dispersed but socially connected
households and yielded insights into the design space for technology to support
everyday cooking.

of these observations, we created a system that helps comic designers in the
early stages of design. Our prototype supports sketching input, allows seamless
movement backward or forward among the different granularities of
representations across the three components, and concurrent use of multiple

%X Carers are people who look after family, partners or friends who could not
manage without them because of frailness, illness or disability. Our
contribution is to show the potential for design to support carers in their
vital caring role, focusing on health information sharing. We describe why it
is important to recognise and consider carers in the design of home health
monitoring technology, and why it is important to help carers maintain their
health and well being. We present design guidelines for home monitoring
technology. These guidelines are distilled from a survey distributed to carers
in a rural part of Scotland on health information sharing. We used these
guidelines to design a new home monitoring system called @Hand. The main
difference with current systems is the focus on facilitating information
sharing between cared-for and carer rather than cared-for and health
professional.

%X Intercultural collaboration is often hampered by the manner in which teams
communicate, or fail to com-municate, their ideas, concerns, and feelings.
Computer-mediated communication and the virtual nature of collaboration tend to
exacerbate such communication issues into problems of conversation dominance,
misattribution, and group conflict. New communication tools have the potential
to mitigate some of these problems by augmenting individuals' and team's
awareness of their communication inputs and processes. We explore how such
feedback affects the communication content, attention distribution, and
affective states of Chinese and American collaborators engaged in a creative
de-sign task. We describe our tool, present preliminary findings from an
ongoing lab experiment, and discuss next steps in our research regarding ways
of detecting the impact of real-time conversation feedback in inter-cultural
collaboration environments.

%X In this paper, we present the design of ViVA, a visual vocabulary for
aphasia. Aphasia is an acquired language disorder that causes variability of
impairments affecting individual's ability to speak, comprehend, read and
write. Existing communication aids lack flexibility and adequate customization
functionality failing to address this variability and to satisfy individual
user needs. We tackle these shortcomings by incorporating adaptive and
adaptable capabilities in ViVA which is designed to assist communication for
users suffering from aphasia. The visual vocabulary for aphasia implements a
novel approach that organizes the words in the vocabulary according to user
preferences, word usage and certain semantic measures, thus continuously
tailoring the tool to the user's profile.

%X There is a gulf between the rhetoric in visualization about the importance
of uncertainty, and the practice of visualization in which uncertainty is
rarely seen other than as a laboratory exercise. We reflect on why something
viewed as fundamental in science and engineering is rarely if ever adopted in
visualization practice. Our analysis is informed both by research progress and
by our own experience in an ongoing industrial case study on modelling and
mapping underground assets, where it would appear that uncertainty plays a
major role. In this case study, we try to identify promoting and limiting
factors. We conclude that the value of uncertainty visualization is severely
limited by the quality and scope of uncertainty data, by the limited confidence
in the data itself, and by the perceptual and cognitive confusion that the
depiction of this data can generate. We hope to broaden the discussion on the
utility of uncertainty in visualization from the purely technical and
perceptual issues to social and organizational factors.

%X Besides the widely promoted advantages the influx of new technology is
bringing to consumers, the disadvantages due to increasing cognitive complexity
of such technological advanced products have also been recognized. Among other
things, an increasing number of unknown field complaints is one of the
evidences. Since consumers often perceive a product's (mal)functioning
differently than designers do, we propose an attributional approach to evaluate
potential product failures. In this paper, we present the results of an
exploratory empirical study to evaluate the attribution of picture quality
failures in LCD televisions for a diverse group of consumers. This approach is
aimed to provide designers better insight into how consumers perceive
(potential) product failures, in order to support critical design decisions in
the product development process.

The research goal of this project is to find the right balance between the

resulting benefit of robust communication between a robot and the user as a
direct consequence of optimized speech recognition. To measure the first
criteria we have explored two methods to evaluate language learnability, namely
Language Tests and analyzing expressed emotions during interaction in an
artificial language. Our results indicate that both have potential in being
used as measurement tools for evaluating the learnability of artificial

interface can be modified to make exchanging secure e-mail nearly effortless.
Our system integrates with social networking services (such as Facebook) to
automatically exchange cryptographic keys between friends. When a user sends a
message to a friend, our system automatically encrypts the contents to thwart
eavesdroppers. When a user receives a message from a friend, Waterhouse uses
the recipient's social network to verify the sender's identity. Our prototype
shows senders' photos as an intuitive indicator of message authenticity. We
describe our planned user study and conclude with directions for future work.

the term "human-computer-paper interaction" considering these phenomena. Using
contextual inquiry and lab-based user study, we explored the switchover in
human-computer-paper interaction and determined what incites this interaction.
Through this study, we attempted to provide considerable insights into the HCI

what the user sees and visually augments surfaces or physical objects the user
is interacting with. WUW projects information onto surfaces, walls, and
physical objects around us, and lets the user interact with the projected

%X Large-scale displays require new interaction techniques because of their
physical size. There are technologies that tackle the problem of interaction
with such devices by providing natural interaction to larger surfaces. We
argue, however, that large-scale displays offer physical freedom that is not
yet being applied to interaction. To better understand how distance affects
user interaction, we present a comparative study of interaction metaphors for
large-scale displays. We present three metaphors: Grab, Point and Mouse. The
metaphors were included in our tests as we felt that each would be more suited
to a specific distance: this is the focus of our tests. We then asked the users
to solve a puzzle using those metaphors from different distances. We discovered
that the point metaphor achieves better results on all tests. However, there is
evidence that grab and mouse remain valid for specific tasks.

%X We present a tool for automatically generating UI layouts for handheld
devices based on design principles. This tool introduces a gestalt approach to
visual interface design rather, complementing prior work on user cost
minimization. We aim to increase user satisfaction using this approach. The
tool automatically generates size and position of widgets drawn from the UI
design heuristics of simplicity, structuring, and proportion. Simplicity refers
to excluding non-core functionality; structuring to contextual grouping, and
proportion to best-practice geometric ratios of width, height, and spacing.
Layouts are generated from device constraints and simple XML containing UI
component hierarchy. These layouts can be directly manipulated using a GUI
editor.

have been developed to support multiple-target selection. In this paper, we
introduce Burst and ZoomTap, two techniques that aim to facilitate accurate and
fast multiple-target acquisition with one-handed thumb operation on touch-based
mobile devices. We compare our two techniques to Shift in a controlled
experiment. The results show that for multiple-target selection, Burst and
ZoomTap can outperform Shift; also according to the questionnaire, participants
prefer Burst and ZoomTap to Shift.

gaming can be blended into other daily activities. However, the players'
current context creates challenges for this parallel activity and therefore,
the game design should enable the players to participate in the game whenever
it is suitable for them. In this paper, we present initial results from a study
which explored one game design solution for this challenge, namely asynchronous
gameplay. We wanted to find out how asynchronous gameplay was used and what the
players' attitudes were towards this new playing style. The results indicate
that the players received asynchronous gameplay positively and that
asynchronous gameplay does not diminish the player's opportunities for winning
the game.

%X Advances in mobile phones and cellular network capabilities have enabled
many opportunities for information access on the move. These capabilities
provide instant access for the mobile user, but have exacerbated the problem of
interaction in a mobile context. Mobile users are often engaged in another task
that makes it difficult for them to filter and interact with their mobile
device at the same time. Mobile multitasking creates an attention deficit for
the user. This paper proposes using butlers as a model to overcome this problem
by offloading the burden of interaction from the user to the device. We
describe how a suite of butlers can opportunistically and proactively offer
information to the user in the moment, allowing mobile users to stay focused on
their task at hand.

particularly when switching social contexts, e.g., from office work to a family
event. To help with such transitions, the audio priming system uses
pre-recorded audio messages to psychologically prepare a person for an upcoming

%X From the most e-mailed stories of the day to the most favorite stocks of the
week, Web interfaces are rife with cues conveying other users' ratings and
reviews of products and services. Do these peer opinions indeed affect our
decisions? And if so, are they as strong in their impact as cues conveying
authority/expertise (i.e., high source credibility)? We explored these
questions through an experiment (N = 243) guided by the heuristic-systematic
model in social psychology. Bandwagon/peer cues are generally more persuasive,
but when they are inconsistent, the authority cue influences decisions. In
general, task involvement promotes systematic processing of these cues.
Interestingly, we found no difference in perceived authority between CNET
Editor's Choice seal and a seal from a fictitious "authority" (Zig!), among
other indications of heuristic processing. We discuss design implications for
user interfaces in general and recommendation agents in particular.

device. In particular, an eyeglass-type head-mounted display is very large for
constant usage. To solve this problem, we propose Brainy Hand, which is a
simple wearable device that adopts laser line, or more specifically, a
mini-projector as a visual feedback device. Brainy Hand consists of a color
camera, an earphone, and a laser line or mini-projector. This device uses a
camera to detect 3D hand gestures. The earphone is used for receiving audio
feedback. In this study, we introduce several user interfaces using Brainy
Hand. (e.g., music player, phone).

%X Architectural designs are not just collections of 3D objects. Architects
have both high-level aesthetic design intent, and intent for the functionality
of the building; these must eventually translate into real-world construction
materials and processes. Physical prototypes are still essential for the
architect and their clients to get a feel for whether designs "work". An
exciting recent development in architecture is the use of industrial robots to
automatically construct 3D prototype architectural models. But programming the
robots requires tedious procedures of low-level commands, far removed from the
designer's intent.
   Adeon is a system that integrates high-level architectural design knowledge,
including aesthetic and stylistic intent, with knowledge about materials and
construction processes, and robot programming code for constructing prototype
3D physical models. It centers around collecting and associating "common sense"
knowledge, expressed in English and converted to a knowledge representation
about the various levels. It provides a graphic editor that allows architects
to draw high-level aesthetic designs, perhaps referencing known styles or
historical examples, and retrieving relevant construction, materials, and cost
information. It automatically produces a robot program for constructing the
prototype. We present examples detailing the design of various styles of brick
walls. Adeon is an interesting example of how to provide an interface for
creative work that spans both high-level and low-level concerns.

rejection rate of interactive consumer electronics products in the field, not
due to broken hardware or software, but due to 'broken expectations' of users.
However, operational methods to capture triggering contextual reasons are not
functional in the industry. In addressing this gap, we propose systematic
analysis of qualitative user feedback data resources from the field by
utilizing our Disconfirmed Expectations Ontology (DEO). DEO provides for an
efficient means to elicit relevant -but currently unrecognizable- feedback from
the field to communicate that to the respective units in a product development
process. We further demonstrate the utilization of DEO on a rich qualitative
data set regarding the Apple iPhone".

interactions, a person performs an action with, toward, or in the vicinity of a
product and then the product reacts to that action. In this paper, however, the
opposite interaction pattern, where a product performs an action to induce a
user reaction, is presented by a new camera, 'Cheese Cam', concept. Cheese Cam
is a camera that can induce unconscious facial reactions in a photography
subject, based on mirror neuron theory and facial mimicry theories. A small
facial expression icon displayed on Cheese Cam's screen induces unconscious
facial reactions in the subject. Experiments were conducted to investigate the
effects of Cheese Cam on the facial reactions of subjects, and the results are
discussed in this paper. Through this study, we explored possibilities of
unconscious interaction.

%X This paper introduces the InSight system, which was designed to explore two
new concepts in social tagging. In this system, we introduce the concept of
community-editable tags, a methodology that allows a community of users to
edit, modify and delete tags of each other. The goal is to improve the quality
of tags, and to reduce the proliferation of incorrect or incomplete tags often
found in social networking systems. We also explore the concept of
"micro-tagging," which has begun to appear in web-based applications. In
"micro-tagging," the user attaches a tag to a subset of large media, such as a
segment in a video or a region of an image. InSight allows users to create and
edit video micro-tags. Users can mark specific time intervals within a video,
and specific spatial locations within video frames, and these tags can be
edited by subsequent users. We also present an empirical study which
demonstrates an improvement in factual tag quality when the community of users
is allowed to edit and delete each others' tags. These results provide a first
step in demonstrating how refining tags would make them more valuable for
search.

behavior through the visualization of the health of coral reefs. By
occasionally consulting the non-intrusive widget, users can immediately

the goal of this application is to make the public become aware of the
connection between their everyday activities and global climate change, which
will educate them about the formerly unseen effects that their actions may have

that modification be made easy". These philosophies can shape a unique
perspective on software usability that has not been addressed thoroughly in the

%X This paper presents a tool for both researchers and designers called the
Device Ecology Mapper, which allows users to share devices they own and
describe to researchers how they believe these devices are connected. We built
this tool from the theoretical perspective of ecology of artifacts in which
designed artifacts do not exist independently, but rather in complex ecosystems
with other artifacts through physical and perceptual connections. We designed
the evaluations of this tool to evaluate the extent to which designers found
the tool valuable and users found the tool true to the way they understand
their ecology of interactive artifacts-rather than how closely user's
perception of their ecology represents how these devices are actually
connected. We found evidence for both perspectives from these studies.

with physical principles such as gravity or inertia. To explore effectiveness
of physical metaphors in interaction design, we conducted an exploratory study
by selecting one specific task where a physical metaphor was applied with
physics: searching for a phone number in a contact list using an inertial
scroll method with a mouse and touch screen interface environment. The result
from this initial study showed that employing a physical metaphor does not
always guarantee an improvement of performance; a different effect can be drawn
according to the interaction style.

%W http://doi.acm.org/10.1145/1520340.1520668
%X In this paper, we propose a new way for measuring key typing pressure when
using off-the-shelf laptop computers. Accelerometers embedded in laptop
computers to protect hard discs from sudden motion are becoming very common.
This paper explores the concept of utilizing this accelerometer for sensing
non-verbal aspects of key typing, such as key typing pressure. This possibility
enables a wide variety of pressure-sensitive user interfaces through the use of
software without requiring any additional hardware/sensors. Such software can
be distributed easily to a substantial number of potential users. To confirm
the feasibility of this idea, we compared typing finger velocities (obtained by
high-speed camera images) with sensor data from an accelerometer embedded in a
laptop computer. We then confirmed that there is a clear correlation between
these two sets of data. We also investigated differences in typing pressure
patterns among different users. By combining keystroke speeds and typing
pressure, we found it is possible to distinguish among users. This feature can
be used for security purposes such as preventing a laptop computer from being
used by non-owners. We also present possible application ideas such as rich
text expression, new types of user interface elements, and authentication.

%X Users of radar control systems and monitoring applications have to
constantly extract essential information from dynamic scenes. In these
environments a critical and elemental task consists of tracking multiple
targets that are moving simultaneously. However, focusing on multiple moving
targets is not trivial as it is very easy to lose continuity, particularly when
the objects are situated within a very dense or cluttered background. While
focus+context displays have been developed to improve users' ability to attend
to important visual information, such techniques have not been applied to the
visualization of moving objects. In this paper we evaluate the effectiveness of
a focus+context technique, referred to as Semantic Depth of Field (SDOF), to
the task of facilitating multiple target tracking. Results of our studies show
an inclination for better performance with SDOF techniques, especially in low
contrast scenarios.

part in Massively Multiplayer On-line Games, such as World of Warcraft. We are
investigating how to use eye gaze as a high bandwidth input modality for the
range of tasks necessary to participate in the game. We approach this from two
directions; in the bottom-up approach we iteratively implement and eva-luate
various gaze-interaction techniques, and in the top-down approach we analyze
the interaction in MMOGs and develop a theory to map games tasks to gaze-based
interaction techniques. We present preliminary results from a recently
conducted set of trials which have studied how well tasks in World of Warcraft
can be carried out using gaze only. We describe this in the context of the

the moving robot. Gaze control was found to be similar to mouse control. This
suggests that robots and wheelchairs may be controlled "hands-free" through
gaze. Low precision gaze tracking and image transmission delays had noticeable

different types of camera movements by measuring subjective responses of users
when exposed to them. In this first stage of research, five important movements
were identified, and evaluated in a pair-wise fashion, resulting in subject

%X Public displays are typically situated in strategic places like town
centers, and in salient positions on walls within buildings. However, currently
most public displays are non-interactive and are typically used for information
broadcasting (TV news, advertisements etc). People passing by pay little
attention to them. As a consequence, public displays are under-utilized in the
everyday world. We are investigating whether use of interactive public displays
might increase people's interaction with one another, with a resulting increase
in sense of community. In this paper we describe the design and first
deployment experiences of a platform-independent, interactive video commenting
system using a large public display in two sections of a large-enrollment
university class. Our preliminary evaluation suggests that students enjoyed the
activity of commenting, that they participated a great deal, and that their
sense of community was greater after using the system. We discuss lessons we
have learned from this initial experience, and describe further work we are
planning using this and similar interactive activities.

%X Jadeite is a new Javadoc-like API documentation system that takes advantage
of multiple users' aggregate experience to reduce difficulties that programmers
have learning new APIs. Previous studies have shown that programmers often
guessed that certain classes or methods should exist, and looked for these in
the API. Jadeite's "placeholders" let users add new "pretend" classes or
methods that are displayed in the actual API documentation, and can be
annotated with the appropriate APIs to use instead. Since studies showed that
programmers had difficulty finding the right classes from long lists in
documentation, Jadeite takes advantage of usage statistics to display commonly
used classes more prominently. Programmers had difficulty finding the right
helper objects and discovering how to instantiate objects, so Jadeite uses a
large corpus of sample code to automatically identify the most common ways to
construct an instance of any given class.

%X Montage is a platform for rendering multiple pages of web content on large
tiled displays (several desktop LCDs arranged in a spatially contiguous
matrix). We discuss the advantages of data visualization using a newsstand
metaphor, showing many content items at once and allowing users to quickly
refine visual searches by walking (physically navigating) closer to specific
data on the display. We have used Montage to build three applications that
demonstrate the variety of applications that are possible on this platform.
These applications have benefits for both everyday use and as research tools.

for personalized, self-paced information retrieval. However, this
personalization conflicts with some of the reasons many people go to museums,
i.e., to socialize, to be with friends, and to discuss the exhibit as they
experience it [1]. We developed an interactive museum experience based on audio
augmented reality that lets the visitor interact with a virtual spatial audio
soundscape. In this paper, we present some new interaction metaphors we use in
the design of this audio space, as well as some techniques to generate a group
experience within audio spaces.

%X The benefits of pet ownership to physical and mental health are extensive
and well documented. Online social networks have the potential to strengthen
these relationships and build community among pet owners. In this work, we
present several results on the difference in behavior between dog and cat
owners in pet-oriented social networks. We extend this analysis to divisions
between urban and rural users. Our results show that there are significant
differences among these groups. We propose a theory for future testing that
more socially isolated the owners are from real-world communities of similar
pet owners, the more active they are in forming social connections on these
websites, and we offer initial evidence to support this. These results show
that these pet social networks are already being used to help support the
human-animal bond online, and that different types of pet owners would benefit
from different types of support within the systems.

%X Behind-the-display interaction has gained popularity for interactions on
handheld devices as researchers have demonstrated the viability of such
interactions on small devices. However, most designs have investigated the use
of direct input behind the screen. We demonstrate that behind-the-display
interaction with cursor input is promising and can be a useful augmentation to
handheld devices. We developed a prototypical system on a PDA to which we
affixed a wireless mouse. The mouse is mounted on the rear of the PDA with the
optical sensor facing outwards. The system is designed to be used with one
hand, and prevents occlusion and finger-reach. Through several applications we
propose the benefits associated with behind-the-display cursor interaction. A
preliminary user evaluation indicates that users can benefit from such an
interaction when operating a handheld using one hand.

In this paper, we explore using sociometric data to study social behaviors of
group shoppers. We hypothesize that the interaction patterns among shoppers
will convey their interest level, predicting probability of purchase. To verify
our hypotheses, we observed co-habiting couples shopping for furniture. We have
verified that there are sensible differences in customer behavior depending on
their interest level. When couples are interested in an item they observe the
item for a longer duration of time and have a more balanced speaking style. A
real-time prediction model was constructed using a decision tree with a
prediction accuracy reaching 79.8% and a sensitivity of 63%.

necessary to record an action. We present PressureText, a text-entry technique
for a pressure augmented mobile phone. In a study comparing PressureText to
MultiTap, we found that despite limited visual feedback for pressure input,
users overall performed equally well with PressureText as with MultiTap.
Expertise was a determining factor for improved performance with PressureText.
Expert users showed a 33.6% performance gain over novices. Additionally, expert
users were 5% faster on average with PressureText than MultiTap, suggesting
that pressure input is a valuable augmentation to mobile phone keypads.

%X Personal event management involves planning when, where and how events
should occur, making sure the event's prerequisites are satisfied, and
developing contingencies for when things go wrong. Conventional calendar and
project management tools, however, only record and visualize explicit human
decisions regarding event specifics.
   We present Event Minder, a calendar program that takes into account the
goals for which the events are scheduled. Users can input descriptions of
events in natural language, mixing high-level objectives, concrete time and
place decisions, and omit "obvious" common sense details. A commonsense
knowledge base provides sensible defaults, and machine learning refines these
defaults with experience. We can make recommendations for alternative plans,
including alternatives that satisfy higher-level goals in different ways as
well as those that meet immediate constraints. Our current system covers
dining-related events, integrating commonsense with domain knowledge about
specific restaurants, bars and hotels.

%X The proliferation of portable devices has transformed our everyday
practices, blurring second and third places. However, almost no research exists
on how the perpetual possession of devices impacts how we escape them. In this
paper, we explore the notion of non-use of portable devices. Drawing from the
results of a multi-step qualitative study, we provide a discussion on how
non-use interplays with the dynamics of everyday life. Specifically, we discuss
practices surrounding hybridities of portable devices and social circles. The
layerings of portables help in de-personalizing interactions through evasions,
pretence, and resistance. We argue that non-use is not a reason for failure,
but is a form of use in itself.

The system tracks a user's body and limb movements as he or she is performing

in the correction of movement and position errors. A number of components
integral to the motion tracking and tactile feedback systems must be bound to
the user's body, and as such, an important goal is to design a lightweight and
minimally inhibitive wearable suit that contains all of these elements.

%X Oftentimes, we would like to distribute call-for-participation messages by
email to people who are potentially interested in the topics of the
corresponding events. Meanwhile, people either broadcast such messages to
everyone in their organizations or maintain a number of mailing lists for
different topics. But both approaches have drawbacks.
   In this paper, we explore the idea of automatically selecting recipients for
broadcasting messages on different topics using people-tagging. In a
collaborative people-tagging system, users can tag each other with the terms
they want, and tags from different users are combined and aggregated. Tags
applied to a user usually describe the user's attributes, such as her
affiliation, expertise, and the projects she has been involved in. We can thus
effectively find interested recipients by matching the content of messages with
people's tags. A prototype of our solution has been implemented for a
real-world and large-scale people-tagging system in IBM.

concepts. The user interface offers a simple visual language and a collection
of ready-to-use devices, filters and interaction techniques. The concept of
semantic zooming enables nevertheless access to more advanced functionality on
demand. Thus, users are able to adjust the complexity of the user interface to
their current need and knowledge.

%X We present a tool for qualitative data discovery that aids researchers in
analyzing synchronized log data with audio collected from multiple computers.
The tool was originally developed for team games in which the goal of play is
to exercise coordination skills. In team coordination games, players cooperate
toward a shared objective by communicating effectively and synchronizing their
game world actions. To evaluate such games, researchers observe communication
between players synchronized with their actions in-game, discovering instances
of team coordination. Coordination is a composite of communication and in-game
action; thus it is essential to observe both in context. The tool enables
simultaneous observation from each player's viewpoint, synchronized with
communication using log files and time-stamped audio. Viewpoints and voice
tracks can be selectively soloed and muted, enabling researchers to focus
attention. The application can be expanded to support logs and audio from other
user studies.

controls as the primary input modality, and the rear-view mirror as a Heads-Up
Display. In addition, we will propose displaying limited amounts of information
to decrease the likeliness of a driver's focus straying away from the road. If
we are able to show that our design is superior to current commercial
navigation devices, we will continue to apply our design points and system
design towards other aspects of In-Vehicle Information Systems.

three main HCI challenges: 1) integrating a problem scenario in the context of
the existing application, 2) providing learners with appropriate feedback
during task performance, and 3) allowing learners to explore the interface
while making sure they complete the task.

As viewers of these visualisation tools, it is up to us to accurately perceive

elements are added, removed, changed and rearranged, sometimes at great pace.
In a complex data set with a lot happening, this can be a strain on the

disrupting their internalised "mental model" of the data, leading to errors in
perception. We present Time Sequences, a novel dual visualisation technique
which dilates the flow of time in the visualisation so that observers are given
proportionally more time to understand changes based on the density of activity
in the visualisation.

%X People are constantly making decisions to answer or ignore cell phone calls
based on inferences derived from partial information about the incoming call.
To gain an understanding of this information deficit we conducted a survey
study of cell phone call handling practices. The results highlight the type and
extent of information desired about incoming cell phone calls. It also shows
that desired information is largely unknown and often misattributed by the
receiver. Our findings can be used by designers to prioritize the presentation
of additional types of call related information on cell phone displays, and in
so doing, empower users to make informed call handling decisions.

%X We live in a hybrid world where standard computers with graphical user
interfaces (GUIs) have become an integral part of our daily life. Additionally,
novel user interfaces like tangible user interfaces (TUIs) are among emerging
interaction styles that offer new potential as tools for supporting creative
tasks and weak-structured workflows. In order to meet the users' needs, the
most suitable user interface for a task should be chosen and different kinds of
user interfaces have to be integrated appropriately. We addressed these topics
and applied a generative framework to structure and analyze a creative work
process in the domain of Art History. On this basis, we designed the
integration of TUI and GUI elements and constructed as well as tested a
tabletop TUI to support creative work.

%X Windows Vista's personal firewall provides its diverse users with a basic
interface that hides many operational details. However, our study of this
interface revealed that concealing the impact of network context on the
security state of the firewall results in mental models that are unclear about
the protection provided by the firewall resulting in an inaccurate
understanding of the firewall configuration. We developed a prototype to
support more contextually complete mental models through inclusion of network
context information. Results from our initial evaluation of the prototype
support our approach of improving user understanding of underlying system
states by revealing hidden context, while considering the tension between
complexity of the interface and security of the system.

use a 3-pronged approach: authoring via metaphor, performance, and automation.
Future work involves using AI to provide feedback to machinima authors,
suggesting sensible attributes for scenes based on prior input by acting as a

%X Although usability is the core aspect of the whole HCI research field, it
still waits for its economic breakthrough. There are some corporations that are
famous for their usable products, but small and medium-sized businesses tend to
prefer features over usability. We think, the primary reason is that there are
no inexpensive methods to at least prevent huge design flaws. We propose the
use of test specifications. Once defined for a domain, these allow
non-usability experts to systematically verify the usability of a given system
without any users involved. We picked a sample domain with some basic tasks and
found strong indication of our hypothesis: test specifications can be applied
by non-experts and are able to find major design flaws. Future work will extend
this method to more complex tasks and evaluate the economic benefit.

%X Web users have been employing numerous methods for recalling websites.
Bookmarks have been around for some time, but the usefulness of such a system
has been under question. The lack of intuitive organization in web browsers
forces users to make arbitrary choices on where to store bookmarks. As a
result, bookmarks are often lost, never to be used again. These web pages a
user bookmarks can say a lot about the user, though. A person's personality is
reflected by the web pages a user visits and deems important enough to
bookmark. By taking the user's bookmarks along with one's browser history and
visualizing them, the user is able to notice things about oneself that he or
she did not notice before. In this paper, we describe the iteration of a tool
that visualizes all of user's bookmarks. We conclude with areas for future
work.

%X We demonstrate how multi-touch hand gestures in combination with foot
gestures can be used to perform navigation tasks in interactive systems. The
geospatial domain is an interesting example to show the advantages of the
combination of both modalities because the complex user interfaces of common
Geographic Information System (GIS) requires a high degree of expertise from
its users. Recent developments in interactive surfaces that enable the
construction of low cost multi-touch displays and relatively cheap sensor
technology to detect foot gestures allow the deep exploration of these input
modalities for GIS users with medium or low expertise. In this paper, we
provide a categorization of multitouch hand and foot gestures for the
interaction with spatial data on a large-scale interactive wall. In addition we
show with an initial evaluation how these gestures can improve the overall
interaction with spatial information.

%X Online voice conversations are becoming ever more popular. People have been
logging online text conversations, but what about voice conversations? Walter
Ong simply states, "written words are residue. Oral tradition has no such
residue or deposit" [6]. However, we do not just want to archive conversations,
we want to enable users to have some meaning in these "logs". We introduce a
project that takes a remote conversation and visualizes it. It does so in a way
that takes volume, pitch and content into account. With this information, the
visualizations display the data in a meaningful way. Users can use these images
in the future to review past conversations whether it is for nostalgia's sake
or to recall some piece of information. In this paper, we describe the early
design and iteration of system for archiving and creating artifacts from remote
audio conversations.

is still much to learn about the motivations and needs of the user. In this
paper, we present the results of interviews and think-aloud studies of
non-programmers working with XML data and a mashup building tool. This work
aims to better understand the users' mental models as they first attempt to use
a novel mashup tool. We identify key areas where breakdowns occur and propose a
future path for research.

human eyes (called submacroscopic objects). The goals of the study are to
explore whether middle school students can understand TAVR in a simulation and
how they use their experience of interacting with TAVRs to refine their mental
model of the sizes of submacroscopic objects.

increasingly important. We investigate handwriting as a text input modality and
assess where to best position the input surface and how to provide feedback.
For this purpose, we created different prototypes that allow text input on the
steering wheel and in the central console, as well as visual feedback on the
input surface and on the dashboard. The results of the study indicate that
handwritten text input on the steering wheel is well-received by the users and
that the visual feedback should be presented in the dashboard area or on the
steering wheel. We also observed that the number of corrective actions and the
remaining errors were significantly smaller (25% less) on the steering wheel
than in the central console and that entering text while driving made people
drive slower.

%X Email is no longer perceived as a communication marvel, but rather as a
constant source of information overload. Several studies have shown that
accessing, managing, and archiving email threatens to affect users'
productivity. While several strategies and tools have been proposed to assuage
this burden, none have attempted to empower users to fight the overload
collaboratively. We hypothesize that despite differences in email management
practices and frequencies of filing among users, there is some degree of
similarity in the end-product of the organizational structures reached by those
working in close cooperative roles (e.g. members of a research group, employees
of an organization). In this paper, we describe a system that enables
collaborators to share their filing strategies among themselves. Tags applied
by one user are suggested to other recipients of the same email, thereby
amortizing the cost of tagging and email management across all stakeholders. We
wish to examine if such system support for semi-automated tagging reduces email
overload for all users, and whether it leads to overall time savings for an
entire enterprise as network effects propagate over time.

workshop aims to attract researchers who approach this topic of tangibility and
children from an empirical or design perspective. The purpose is to obtain a
good picture of what benefits we expect tangibility to provide (including novel
and future applications), establish what is the current empirical evidence to
support such claims (or what is missing), and motivate appropriate evaluation
methodologies for children.

of crowds are distinct from those of smaller group formations. In this workshop
we want to think about new opportunities for designing crowd-centric

large scale crowd computing. The workshop will explore themes related to
crowd-centric computing through hands-on crowd-based exercises, position papers

%X Researchers in human-computer interaction and allied fields are increasingly
interested in using new sensing capabilities to create context-aware interfaces
and devices for the home. Data from sensors worn on the body or installed in an
environment can be used by algorithms to infer what activities the home
occupant may be engaged in and enable applications to respond accordingly. This
one-day CHI'09 workshop would convene a multidisciplinary group of researchers
to discuss strategies for creating community resources that might accelerate
research on development of home technologies. In particular, the participants
will discuss how to collaboratively gather high quality synchronized data
streams from real homes, as well as qualitative material about home occupants
and their behaviors. The resultant datasets could facilitate work on context
modeling and enable researchers in other areas of HCI to explore contextual
factors influencing the use of technology in naturalistic settings. The outcome
of the workshop will be a community index of existing shared datasets of home
behavior and guidelines for those interested in creating and disseminating new
datasets.

%X Natural user interfaces (NUI) such as multitouch and surface computing are
positioned as the next major evolution in computing and user interfaces. Just
graphical user interfaces (GUIs) brought unprecedented interaction capabilities
to their command-line predecessors, we believe multitouch and surface computing
will spawn novel ways to interact with media and improve social usage patterns.
Since experimentation and deployment are currently limited, the exploration of
applications and interfaces in this area is still at an early stage.

%X New technologies for supporting the provision of healthcare are increasingly
pervasive. While healthcare computing previously referred to a desktop computer
within the consulting room, we are now seeing an ever broader range of
software, hardware and settings. This workshop is concerned with how to conduct
evaluations which allow assessment of the overall impact of technology. The
workshop will explore challenges and approaches for evaluating new interactions
in healthcare. In this paper we outline the goals for this workshop and
summarize the issues and questions it intends to explore.

%X Social Mediating Technologies (SMTs) range from e-mail to social networking
sites and community websites. The popularity of these technologies is
increasing rapidly, yet we have little understanding about how and why people
find these technologies so appealing. The research challenge is to try to
understand the causal drivers for usage of social technologies, and
theory-based understanding of how the affordances of such technologies meet
with people's cognitive and social needs. This workshop will provide a forum
for researchers to synthesise current knowledge on SMTs and map out future
research directions.

in end user programming (EUP), all focused on the web. This work is spread
across a variety of institutions and has been published in a variety of
conference venues, including CHI, UIST, IUI, and WWW. This workshop will bring
these researchers together for a common discussion, with the following goals:
establish a sense of community amongst researchers in this area; discuss common
problems and lessons learned about doing research in EUP for the web; define a
standard corpus of tasks that can be used to evaluate current and future EUP
systems; and plan the publication of an edited book on the topic of end user
programming for the web.

%X Time serves as a basis for measuring the occurrence and evolution of natural
phenomena, and governs the coordination of many of our everyday life
activities. As the capacities of our digital tools have grown, they have begun
to make readily available to us unprecedented quantities of new, rich,
structured temporal information about the people and things in our lives. This
abundance of information has laid open avenues for new tools and applications
-- applications which, in turn, introduce new demands on interface mechanisms
used to display, represent and interact with temporal data.
   This workshop, the second in a series on Capturing, Interacting with and
Visualizing Temporal Data, will focus on such demands, examining interaction
challenges emerging across new application domains.

%X Despite the enormous commercial successes of products such as Nintendogs,
very little is known about people's interactions with artificial
representations of animals. However there is an increasing body of research in
different disciplines which could be used to better understand such
interactions. The Reign of Catz & Dogz at CHI 2009 is a one day workshop which
will bring together researchers in an inter-disciplinary, international and
multi-cultural setting to explore the relevant issues surrounding interactions
with virtual creatures and the role such creatures will play in the future.

%X Internet-based, mobile and pervasive technologies provide the means for
older people to establish and maintain intergenerational relationships over
long distances. However the significance of this intergenerational context has
been largely ignored when considering potential interactions and the design of
new technologies. This workshop aims to explore what the important issues are
when considering intergenerational contact as a significant context for design.
The overarching objective of this workshop is to identify key research themes
in respect of intergenerational communication and its implications for the
design of interactive systems.

%X The focus of this workshop is on the development of interfaces for
long-term, voluntary use, spanning dozens, if not thousands, of interactions,
and in which maintenance of user adherence to a desired interaction usage
pattern is of primary interest. Domains in which these issues are important
include: wellness applications, such as long-term exercise or diet promotion;
web site "stickiness"; multi-session intelligent tutoring systems; and computer
games. This one-day CHI'09 workshop brings together researchers from a wide
spectrum of disciplines who share a common interest in finding theoretical
frameworks, models, and design methodologies to support longitudinal HCI.

%* (c) Copyright 2009 ACM
%W http://doi.acm.org/10.1145/1520340.1520747
%X This workshop aims to further the understanding of the challenges relating
to the evaluation methods of usability and user experience that are specific to
Reality-Based Interaction (RBI), and to identify effective practical responses
to these challenges. The emergence of Post-WIMP interfaces has led to new ways
of interacting with technologies. However, there are still no integrated ways
of evaluating the usability and user experience of these interfaces. Developers
and designers are left to discover their own metrics and evaluation methods.
This approach presents problems, in that the metrics used in each case may
provide results that are neither valid nor meaningful. For this reason, the
time is ripe to integrate the methods that have been developed for evaluating
interfaces that belong to the RBI umbrella. The measures and techniques will
then be turned into a framework that enables designers of RBI interfaces to
select appropriately existing methods and tools to evaluate systematically the
usability and user experience of their prototypes and products. Reusing and
adapting validated evaluation approaches can not only avoid reinventing the
wheel and wasting time but also further improve and consolidate these
approaches. Such a framework will also provide a basis for comparison between
designs of RBI interfaces in different application contexts.

%X The confluence of two major trends in scientific research is leading to an
upheaval in standard scientific practice. A new generation of scientists,
working in large-scale collaborations, is repurposing social software for use
in collaborative science. Existing social tools such as chat, IM, and
FriendFind are being adopted and modified for use as group problem-solving
facilities. At the same time, exponentially greater and more complex datasets
are being generated at a rate that is challenging the limits of current
hardware, software, and human cognitive capability. A concerted effort to
develop new software tools to handle this data tsunami is redefining the
collaboratory and represents a new frontier for computer supported cooperative
work.
   We are hoping this workshop can build community among researchers studying
and/or building software for scientific collaborations.
