Summary: In this paper, we explore how shape changing interfaces might be used to
communicate emotions. We present two studies, one that investigates which
shapes users might create with a 2D flexible surface, and one that studies the
efficacy of the resulting shapes in conveying a set of basic emotions. Results
suggest that shape parameters are correlated to the positive or negative
character of an emotion, while parameters related to movement are correlated
with arousal level. In several cases, symbolic shape expressions based on clear
visual metaphors were used. Results from our second experiment suggest
participants were able to recognize emotions given a shape with a good accuracy
within 28% of the dimensions of the Circumplex Model. We conclude that shape
and shape changes of a 2D flexible surface indeed appear able to convey
emotions in a way that is worthy of future exploration.

Summary: The use of the skin as interaction surface is gaining popularity in the HCI
community. To offer an alternative perspective on how we might design on-body
interactions, we conducted a questionnaire asking if, how, and why people mark
their skin. We found that visibility and ease of access were important factors
for choosing to mark the body. We also found that while some participants
consider marking the body as a private activity, most participants perceive
such markings as a public display. This tension between the personal nature of
on-body interaction and the skin as a public display, as well as hedonic uses
of body markings, present interesting design challenges.

Summary: In recent years, several workshops and an increasing number of scientific
publications have focused on shape-changing interfaces. This work has explored
prototypes, theory and evaluations across a variety of domains, including:
aesthetic experience, affective computing, adaptive affordances, data
visualisation, and remote communication support, to name only a few. The aim of
this workshop is to bring to light and discuss the different underlying
perspectives and visions on shape-changing interfaces within the community,
arriving at a shared, cross-discipline vocabulary for discussing the design
space. Participants will share their personal perspective and explore others'
perspectives through hands-on prototyping and facilitated sketching tasks.
Leaving this workshop, participants will be equipped with a clearer
understanding of the different concepts being explored within the community and
with a vocabulary through which to describe the intricacies and considerations
of their work in the future.

Summary: ReFlex is a flexible smartphone with bend input and active haptic feedback.
ReFlex's features allow the introduction of sensations such as friction or
resistance. We report results from an experiment using ReFlex in a targeting
task, as well as initial users' reactions to the prototype. We explore both
absolute and relative tactile haptic feedback, paired with two types of bend
input mappings: position-control and rate-control. We observed that
position-controlled cursors paired well with relative bend feedback, while
rate-controlled cursors paired well with absolute bend feedback to indicate
targets. We also explored an eyes-free condition. Results suggest that while
eyes-free, haptic feedback conditions were more error-prone than visual-only
conditions, the size of the error was relatively small, and users were able to
complete the task in all cases. We present two application scenarios that take
advantage of the unique input and output modalities of ReFlex and discuss its
potential for within document navigation.

Summary: Technology mediates the relationship we have with ourselves, others and the
world around us. This paper describes an installation that explores minimum
conditions for mediation, using a touch sensitive telerobot with an actuated
head. People wishing to use the telerobot wear a head-mounted display and a
head-tracking device. This enables them to see what the robot sees while the
movements of the robot's head are synchronized to those of their own head.
Vibration motors are attached to the user's body and vibrate when the robot is
touched. This installation allows for playful exploration of mediation as well
as adopting other perspectives through technology. When interacting with others
through the robot, the installation enables reflection on the role of touch in
communication and technology. Used by one's self, the installation allows us to
perceive our bodies from a third person perspective.

Summary: We introduce PrintPut, a method for 3D printing that embeds interactivity
directly into printed objects. PrintPut uses conductive filament to offer an
assortment of sensors that an industrial designer can easily incorporate into
their 3D designs, including buttons, pressure sensors, sliders, touchpads, and
flex sensors. PrintPut combines physical and interactive sketching into the
same process: seamlessly integrating sensors onto the surfaces of 3D objects,
without the need for external sensor hardware.

Summary: Interaction designers require simple methods of creating ad-hoc sensors for
prototyping interactive objects. Methods of creating custom sensing solutions
commonly include various capacitive and resistive techniques. Near-infrared
(IR) sensing solutions can be used as an alternative to these established
methods. There are many situations in which IR sensors may be a preferred
method of input, such as grasp detection and touch interactions on the skin. In
this paper we outline the general approach for designing IR sensors and discuss
the design and applications of two custom sensors.

Summary: Mobile devices can provide people with contextual information. This
information may benefit a primary activity, assuming it is easily accessible.
In this paper, we present DisplaySkin, a pose-aware device with a flexible
display circling the wrist. DisplaySkin creates a kinematic model of a user's
arm and uses it to place information in view, independent of body pose. In
doing so, DisplaySkin aims to minimize the cost of accessing information
without being intrusive. We evaluated our pose-aware display with a rotational
pointing task, which was interrupted by a notification on DisplaySkin. Results
show that a pose-aware display reduces the time required to respond to
notifications on the wrist.

Summary: We present GoonQuad, an emotive quadruped capable of expressing emotional
behaviours as a response to human touch. GoonQuad comprises five prerecorded
states: angry, cheerful, sleepy, confused and a baseline breathing state. Each
state is triggered by human touch in areas specified by the eyebrows and a
tattoo, painted with conductive ink. Moreover, GoonQuad is capable of recording
and replaying movements via direct user manipulation. To enable the robot to
record and replay new motions, analog feedback servos were embedded in the 3D
printed structure. Our aim was to develop a system where users can interact
with a robot naturally and the robot can adapt to this natural interaction.

Summary: We present Mood Fern: digital flora which responds to touch. Depending on
the length and intensity of the touch a subset of leaves physically react. The
leaves respond on a spectrum of slight oscillation, imitating the effects of
swaying in a slight breeze, to complete deformation, as if they were physically
trying to respond in a similar manner. Mood Fern's reference to nature
highlights its appeal to calm computing. Painted capacitive sensors mimic the
appearance of leaf veins and Flexinol SMA wire is used to actuate The Mood
Fern's paper structures.

Summary: We present PaperTab, a paper tablet computer that allows physical
manipulation of windows embodied in multiple flexible displays. PaperTab offers
the benefits of updating electronic information on the fly, while maintaining
the haptic/kinesthetic feedback of tangible documents, as each document is a
fully functional, paper-like E Ink display. We present windowing techniques for
a paper computer that relies on multiple physical windows. Our between-display
interactions are based on the proximity of a display to the user. They are
categorized into hot zones, for active editing, warm zones for temporary
storage, and cold zones for long-term storage. Our within-display interactions
use pointing with a display as a focus+context tool.

Summary: We present Papertab, a paper computer with multiple 10.7" functional touch
sensitive flexible electrophoretic displays. Papertab merges the benefits of
working with electronic documents with the tangibility of paper documents. In
Papertab, each document window is represented as a physical, functional,
flexible e-paper screen called a displaywindow. Each displaywindow is an
Android computer that can show documents at varying resolutions. The location
of displaywindows is tracked on the desk using an electro-magnetic tracker.
This allows for context-aware operations between displaywindows. Touch and bend
sensors in each displaywindow allow users to navigate content.

Summary: With WristFlicker, we detect wrist movement through sets of stretch sensors
embedded in clothing. Our system supports wrist rotation
(pronation/supination), and both wrist tilts (flexion/extension and
ulnar/radial deviation). Each wrist movement is measured by two opposing
stretch sensors, mimicking the counteracting movement of muscles. We discuss
interaction techniques that allow a user to control a music player through this
lightweight input.
