When the user is engaged with a real-world task it can be
inappropriate or difficult to use a smartphone. To address this
concern, we developed ShoeSense, a wearable system consisting in
part of a shoe-mounted depth sensor pointing upward at the wearer.
ShoeSense recognizes relaxed and discreet as well as large and
demonstrative hand gestures. In particular, we designed three gesture
sets (Triangle, Radial, and Finger-Count) for this setup, which can be
performed without visual attention. The advantages of ShoeSense are
illustrated in five scenarios: (1) quickly performing frequent operations
without reaching for the phone, (2) discreetly performing operations
without disturbing others, (3) enhancing operations on mobile devices,
(4) supporting accessibility, and (5) artistic performances. We present a
proof-of-concept, wearable implementation based on a depth camera
and report on a lab study comparing social acceptability, physical and
mental demand, and user preference. A second study demonstrates a
94-99% recognition rate of our recognizers.
Mobile ActDresses: Programming Mobile Devices
by Accessorizing i407

Mobile ActDresses is a design concept where existing practices of
accessorizing, customization and manipulation of a physical
mobile device is coupled with the behaviour of its software. With
this interactivity demonstrator we will provide a hands on
experience of doing this kind of playful manipulation. We provide
two examples for how to implement Mobile ActDresses using
quick’n dirty hacks to create custom shells and jewellery for
controlling the behaviour of the phone.
AMARA: The Affective Museum of Art Resource

This interactive system uses an embedded agent for question-based
art collection search on the platform of the Indianapolis Museum of
Art website. Unlike a keyword search box, AMARA helps users browse
and search for artwork by asking them simple questions with answers
mapped to social tags. Thus, the users do not need to be subject
matter experts to input specific terms to search. In designing AMARA,
we focused on creating an enjoyable browsing experience and
helping users to determine their known and unknown art preferences.

Scoop! A Movement-based Math Game Designed
to Reduce Math Anxiety i410

In this paper, we describe Scoop!, a movement-based game
designed to reduce math anxiety. The game makes use of
research on the effects of ‘power poses’ to explore whether
movement mechanics can shift feelings about math for players.
The Interactivity demonstration includes both a ‘high power’,
Kinect-driven version of the game, and a ‘low power’, track-paddriven
version of the game. CHI attendees can try out both
versions to physically experience the effects.
EyeRing: An Eye on a Finger i411

Finger-worn devices are a greatly underutilized form of interaction
with the surrounding world. By putting a camera on a finger we
show that many visual analysis applications, for visually impaired
people as well as the sighted, prove seamless and easy. We
present EyeRing, a ring mounted camera, to enable applications
such as identifying currency and navigating, as well as helping
sighted people to tour an unknown city or intuitively translate
signage. The ring apparatus is autonomous, however our system
also includes a mobile phone or computation device to which it
connects wirelessly, and an earpiece for information retrieval.
Finally, we will discuss how different finger worn sensors may be
extended and applied to other domains.
