Summary: Research in learning analytics and educational data mining has recently
become prominent in the fields of computer science and education. Most scholars
in the field emphasize student learning and student data analytics; however, it
is also important to focus on teaching analytics and teacher preparation
because of their key roles in student learning, especially in K-12 learning
environments. Nonverbal communication strategies play an important role in
successful interpersonal communication of teachers with their students. In
order to assist novice or practicing teachers with exhibiting open and
affirmative nonverbal cues in their classrooms, we have designed a multimodal
teaching platform with provisions for online feedback. We used an interactive
teaching rehearsal software, TeachLivE, as our basic research environment.
TeachLivE employs a digital puppetry paradigm as its core technology.
Individuals walk into this virtual environment and interact with virtual
students displayed on a large screen. They can practice classroom management,
pedagogy and content delivery skills with a teaching plan in the TeachLivE
environment. We have designed an experiment to evaluate the impact of an online
nonverbal feedback application. In this experiment, different types of
multimodal data have been collected during two experimental settings. These
data include talk-time and nonverbal behaviors of the virtual students,
captured in log files; talk time and full body tracking data of the
participant; and video recording of the virtual classroom with the participant.
34 student teachers participated in this 30-minute experiment. In each of the
settings, the participants were provided with teaching plans from which they
taught. All the participants took part in both of the experimental settings. In
order to have a balanced experiment design, half of the participants received
nonverbal online feedback in their first session and the other half received
this feedback in the second session. A visual indication was used for feedback
each time the participant exhibited a closed, defensive posture. Based on
recorded full-body tracking data, we observed that only those who received
feedback in their first session demonstrated a significant number of open
postures in the session containing no feedback. However, the post-questionnaire
information indicated that all participants were more mindful of their body
postures while teaching after they had participated in the study.

Summary: Millions of people rely on subtitles when watching video content. The
current change in media viewing behaviour involving computers has resulted in a
large proportion of people turning to online sources as opposed to regular
television for news information. This work analyses the user experience of
viewing subtitled news videos presented as part of a web page. A lab-based user
experiment was carried out with frequent subtitle users, focusing on
determining whether changes in video dimension and subtitle location could
affect the user experience attached to viewing subtitled content. A significant
improvement in user experience was seen when changing the subtitle location
from the standard position of within a video at the bottom to below the video
clip. Additionally, participants responded positively when given the ability to
change the position of subtitles in real time, allowing for a more personalised
viewing experience. This recommendation for an alternative subtitle positioning
that can be controlled by the user is unlike current subtitling practice. It
provides evidence that further user-based research examining subtitle usage
outside of the traditional television interface is required.

Summary: In this paper we present the results of an experiment investigating a
participant's sense of presence by examining the correlation between visual
information and physical actions in a mixed reality environment. There have
been many approaches to measure presence in a virtual reality environment, such
as the "Pit" experiment, a physiological presence experiment that used a
person's fear of heights to test body ownership. The studies reported in these
prior works were conducted to measure the extent to which a person feels
physical presence in virtual worlds [1-3]. Here, we focus on situational
plausibility and place illusion in mixed reality, where real and virtual
content coexist [4]. Generally, the phenomenon we are studying is called
telepresence: an aroused sensation of 'being together in the same real
location' between users [5].

Summary: The Internet has continued to evolve, becoming increasingly media rich. It
is now a major platform for video content, which is available to a variety of
users across a range of devices. Subtitles enhance this experience for many
users. However, subtitling techniques are still based on early television
systems, which impose limitations on font type, size and line length. These are
no longer appropriate in the context of a modern web-based culture.
In this paper we describe a new approach to displaying subtitles alongside
the video content. This follows the responsive web design paradigm enabling
subtitles to be formatted appropriately for different devices whilst respecting
the requirements and preferences of the viewer. We present a prototype
responsive video player, and report initial results from a study to evaluate
the value perceived by regular subtitle users.

Summary: As part of normal interpersonal communication, people send and receive
messages with their body, especially with their hands. Gestures play an
important role in teacher-student classroom interactions. In the domain of
education, many research projects have focused on the study of such gestures
either in real classrooms or in tutorial settings with experienced teachers.
Novice teachers especially need to understand the messages they are sending
through nonverbal communication as this can have a major effect on their
ability to manage behaviors and deliver content. Such learning should optimally
occur before experiencing the real classroom. To assist in this process, we
have developed a virtual classroom environment -- TeachLivE -- and used it for
teacher practice, reflection and assessment. This paper investigates the way
teachers use gestures in the virtual classroom settings of TeachLivE. Biology
and algebra teachers were evaluated in our study. Analysis of video recordings
from real and virtual environment seems to indicate that algebra teachers
gesture significantly more often than biology teachers. These results have
implications for providing useful feedback to participant teachers.

Summary: Research exploring the implementation of surrogates has included areas such
as training (Chuah et al., 2013), education (Yamashita, Kuzuoka, Fujimon, &
Hirose, 2007), and entertainment (Boberg, Piippo, & Ollila, 2008).
Determining the characteristics of the surrogate that could potentially
influence the human's behavioral responses during human-surrogate interactions
is of importance. The present work will draw on the literature about
human-robot interaction (HRI), social psychology literature regarding the
impact that the presence of a surrogate has on another human, and
communications literature about human-human interpersonal interaction. The
review will result in an experimental design to evaluate various dimensions of
the space of human-surrogate characteristics influence on interaction.

Summary: This paper presents an architecture to control avatars and virtual
characters in remote interaction environments. A human-in-the-loop (interactor)
metaphor provides remote control of multiple virtual characters, with support
for multiple interactors and multiple observers. Custom animation blending
routines and a gesture-based interface provide interactors with an intuitive
digital puppetry paradigm. This paradigm reduces the cognitive and physical
loads on the interactor while supporting natural bi-directional conversation
between a user and the virtual characters or avatar counterparts. A
multi-server-client architecture, based on a low-demand network protocol,
connects the user environment, interactor station(s) and observer station(s).
The associated system affords the delivery of personalized experiences that
adapt to the actions and interactions of individual users, while staying true
to each virtual character's personality and backstory. This approach has been
used to create experiences designed for training, education, rehabilitation,
remote presence and other-related applications.

Summary: In this paper we present a method of segmenting instrumented activities of
daily living (IADL) using kinematic criterion coupled with sensor technology.
To collect our training data we asked four neurologically healthy individuals
to make a total of 60 cups of tea with a set order of ASs. We then evaluated
our IADL segmentation technique in healthy individuals and patients with limb
apraxia, and demonstrate that combining kinematic criterion with sensor data is
provides an accurate means to segment IADL's into relevant ASs.

Summary: The aim of this study was to consider the potential uses of human error
identification (HEI) techniques in the development of a Personal Healthcare
System (PHS) capable of delivering cognitive rehabilitation of activities of
daily living (ADL) for stroke patients with limb apraxia (i.e., CogWatch). HEI
techniques were able to predict a number of apraxic errors, as well as the
associated consequences. The results of the present study indicate that HEI
analysis is a useful tool in the design of cognitive systems that seek to
reduce or eliminate errors in apraxic populations. The results will be
implemented in the CogWatch system and will be used to develop error reduction
strategies that prevent errors from occurring, and to provide post-error
feedback to help the user correct their actions.

Summary: This research is part of an ongoing effort on the efficacy and user
experience of TLE TeachLivE™, a 3D mixed reality classroom with simulated
students used to facilitate virtual rehearsal of pedagogical skills by
teachers. This research investigated a potential relationship between efficacy,
in terms of knowledge acquisition and transfer, and user experience in regard
to presence, suspension of disbelief, and immersion. The initial case studies
examining user experience of presence, suspension of disbelief, and immersion
were used to develop a presence questionnaire revised from the work of Witmer
and Singer (1998) to address the TLE TeachLivE™ mixed reality
environment. The findings suggest that targeted practice, authentic scenarios,
and suspension of disbelief in virtual learning environments may impact
learning.

Summary: In this paper we describe research being conducted on a mixed reality
simulation called MEteor that is designed for informal physics learning in
science centers. MEteor is a 30 x 10 foot floor area where participants use
their bodies to interact with projected astronomical imagery. Participants walk
and run across the floor to simulate how objects move in space, and to enact
basic physics principles. Key to the success of this learning environment is an
interface scheme that supports the central metaphor of "child as asteroid."
Using video data collected in our studies we examine the extent to which
feedback mechanisms and interface conventions strengthened the metaphorical
connection, and we describe ways the interaction design can be improved for
future iterations.

Summary: ChronoLeap: The Great World's Fair Adventure utilizes the educational
potential of immersive 3D virtual venues for children and early adolescents
between 9 and 13. Virtual reality environments transport the mind beyond the 2D
bounds of text or photographs; they engage the imagination and can be a
powerful tool for conveying educational content [1]. ChronoLeap leverages these
innate qualities and weaves together the individual threads of single
disciplines into a multi-disciplinary tapestry of web-based exploration through
the 1964/65 New York World's Fair. Through their myriad of pavilions and
exhibits, World Fairs offer links to science, technology, engineering,
mathematics, art and humanities topics. ChronoLeap provides an immersive 3D
environment with highly accurate and detailed models, and merges it with games
and themes designed to provide users an educational STEAM environment. The
project is a collaborative effort between the University of Central Florida,
Queens Museum of Art and New York Hall of Science.

Summary: Stroke frequently causes apraxia, particularly if it affects the
left-hemisphere. A major symptom of apraxia is the presence of deficits during
the execution and organization of activities of daily living (ADL). These
deficits may substantially limit the capacity of stroke patients to live
independently in their home environment. Traditional rehabilitative techniques
to improve ADL function revolve around physical and occupational therapy. This
approach is labor intensive and constraints therapy to clinical environments.
The CogWatch system provides an supplementary means of rehabilitation that is
based on instrumented objects and ambient devices that are part of patients'
everyday environment and can be used to monitor behavior and progress as well
as re-train them to carry out ADL through persistent multimodal feedback.

Summary: The aim of this paper is to present a requirement for assessing the quality
of data and the development of efficient methods of valuing and exchanging data
among Web Observatories. Using economic and business theory a range of concepts
are explored which include a brief review of existing business structures
related to the exchange of goods, data or otherwise. The paper calls for a
wider discussion by the Web Observatory community to begin to define relevant
criteria by which data can be assessed and improved over time. The economic
incentives are addressed as part of a price by proxy framework we introduce,
which is supported by the need to strive for clear pricing signals and the
reduction of information asymmetries. What is presented here is a way of
establishing and improving data quality with a view to valuing data exchanges
that does not require the presence of money in the transaction, yet it remains
tied to revenue generation models as they exist online.

Summary: Multi-touch, which has been heralded as a revolution in human -- computer
interaction, provides features such as gestural interaction, tangible
interfaces, pen-based computing, and interface customization -- features
embraced by an increasingly tech-savvy public. However, multi-touch platforms
have not been adopted as "everyday' computer interaction devices that support
important text entry intensive applications such as word processing and
spreadsheets. In this paper, we present two studies that begin to explore user
performance and experience with entering text using a multi-touch input. The
first study establishes a benchmark for text entry performance on a multi-touch
platform across input modes that compare uppercase-only to mixed-case,
single-touch to multi-touch and copy to memorization tasks. The second study
includes mouse style interaction for formatting rich text to simulate a word
processing task using multi-touch input. As expected, our results show that
users do not perform as well in terms of text entry efficiency and speed using
a multi-touch interface as with a traditional keyboard. Not as expected was the
result that degradation in performance was significantly less for memorization
versus copy tasks, and consequently willingness to use multi-touch was
substantially higher (50% versus 26%) in the former case. Our results, which
include preferred input styles of participants, also provide a baseline for
further research to explore techniques for improving text entry performance on
multi-touch systems.

Summary: An evolution of remote control puppetry systems is presented. These systems
have been designed to provide high quality trainer to trainee communication in
game scenarios containing multiple digital puppets with interaction occurring
over long haul networks. The design requirements were to support dynamic
switching of control between multiple puppets; suspension of disbelief when
communicating through puppets; sensitivity to network bandwidth requirements;
and as an affordable tool for professional interactive trainers (Interactors).
The resulting system uses a novel pose blending solution guided by a scaled
down desktop range motion capture controller as well as traditional button
devices running on an standard game computer. This work incorporates aspects of
motion capture, digital puppet design and rigging, game engines, networking,
interactive performance, control devices and training.

Summary: Believable agents have applications in a wide range of human computer
interaction-related domains, such as education, training, arts and
entertainment. Autonomous characters that behave in a believable manner have
the potential to maintain human users' suspense of disbelief and fully engage
them in the experience. However, how to construct believable agents, especially
in a generalizable and cost effective way, is still an open problem. This paper
compares the two common approaches for constructing believable agents --
human-driven and artificial intelligence-driven interactive characters -- and
proposes a mixed-initiative approach in the domain of interactive training
systems. Our goal is to provide the user with engaging and effective
educational experiences through their interaction with our system.

Summary: We describe the development and use of a mixed reality (MR) testbed to
evaluate potential scenarios that may alleviate performance deficits in
subjects who may be experiencing cognitive deficiencies, such as posttraumatic
stress disorder (PTSD). The system blends real world sensory data with
synthetic enhancements in the visual and aural domains. It captures user
actions (movement, view direction, environment interaction, and task
performance) and psychophysical states (engagement, workload, and skin
conductivity) during an MR-enabled experience in order to determine task
performance in the context of a variety of stimuli (visual and aural
distracters in time-constrained activities). The goal is to discover triggers
that affect stress levels and task performance in order to develop
individualized plans for personal improvement.

Summary: Large tactical teams must demonstrate integrative performance as tens to
thousands of operators perform within highly dynamic, complex, and
unpredictable environments. The development of methods for capturing integrated
performance and the achievement of team goals, while also allowing for and even
embracing adaptive performance, is challenging. However, as Distributed Mission
Training (DMT) systems continue to mature and are increasingly representative
of important training opportunities in the military, diagnostic performance
assessment systems are needed to ensure training quality. In this paper, we
propose a methodological framework for team performance that is responsive to
the performance measurement challenges found within DMT systems. The approach
is illustrated within a U.S. Navy research and development program called
Debriefing Distributed Simulation-Based Exercises (DDSBE).

Summary: Recent research on the design of virtual environments has focused on the
important perceptual characteristics of man-made "carpentered" environments,
rather than on VEs of natural environments. The present research examines
memory for characteristics of natural settings consisting of virtual trees.
Participants viewed either a symmetrical or asymmetrical virtual tree and then
re-created it using custom-designed tree editing software. Memory was more
accurate for the symmetrical tree. Across trees, participants were most
accurate re-creating gross structural dimensions of a tree such as height and
leaf size, and were particularly inaccurate at re-creating the curvature of
tree branches. Our conclusion is that the design of virtual environments should
focus on accurately representing gross structural properties of trees, rather
than on using high levels of detail to accurately portray trunk and branch
curvature.

Summary: The Virtual Academy is an educational model based on multiage teams of
students and adults working through the Internet to build and use virtual
worlds for educational purposes. These collaborations are mediated by a range
of tools ranging from electronic mail to hypermedia and video links, and result
in the creation of simulation-based role-playing adventure games within the
ExploreNet software environment. ExploreNet is an Internet-based multimedia,
multiuser domain constructed specifically for educational experimentation.
This article describes the Virtual Academy Model, the ExploreNet software
system, and an experiment conducted in the spring of 1995. The article
describes the evolution of features of ExploreNet's user interface and their
relevance to collaborative work by children.
