EyeRing: An Eye on a Finger

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.

There are a number of mobile shopping aids and recommender
systems available, but none can be easily used for a weekly shop at a
local supermarket. We present a minimal, mobile and fully functional
lambent display that clips onto any shopping trolley handle,
intended to nudge people when choosing what to buy. It provides
salient information about the food miles for various scanned food
items represented by varying lengths of lit LEDs on the handle and a
changing emoticon comparing the average miles of all the products
in the trolley against a social norm. A fast and frugal shopping
challenge is presented, in the style of a humorous reality TV show,
where the pros and cons of using various devices to help make
purchase decisions are demonstrated by shoppers in a grocery store.
Ferro Tale: Electromagnetic Animation Interface

In this video we demonstrate the idea and the prototypeof an
electromagnetic animation interface, ferro tale.Ferromagnetic
particles, such as iron filings, have veryfascinating characteristics.
Therefore they are widely usedin art, education and as toys.
Besides their potential toenable visual and tactile feedback and to
be used as amedium for high resolution tangible input, peoples
naturaldesire to engage and explore the behavior of this
materialmakes them interesting for HCI.Inspired by the
expressiveness of sand drawing, we want toexplore ways to use an
electromagnetic array, camerafeedback, computer vision, and
ferromagnetic particles toproduce animations. The currently used
magneticactuation device consists of a 3 by 3 coil array. Even
withsuch a small number of actuators, we are abledemonstrate
several animation examples.

How can new technologies be designed to facilitate comparable
cultural experiences that are accessible by both blind and sighted
audiences? An immersive theatre experience was designed to
raise awareness and question perceptions of ‘blindness’, through
enabling both sighted and blind members to experience a similar
reality. We designed the Haptic Lotus, a novel device that changes
its form in response to the audience’s journey through the dark.
The device was deliberately designed to be suggestive rather than
directive to encourage enactive exploration for both sighted and
blind people. During a week of public performances in Battersea
Arts Centre in London 150 sighted and blind people took part.
People were seen actively probing the dark space around them
and for many the Haptic Lotus provided a strong sense of
reassurance in the dark.During a week of public performances in

Looking Glass: A Field Study on Noticing Interactivity
of a Shop Window

In this paper we present our findings from a lab and a field study
investigating how passers-by notice the interactivity of public
displays. We designed an interactive installation that uses visual
feedback to the incidental movements of passers-by to
communicate its interactivity. In the field study, three displays were
installed during three weeks in shop windows, and data about 502
interaction sessions were collected. Our observations show: (1)
Significantly more passers-by interact when immediately showing
the mirrored user image (+90%) or silhouette (+47%) compared to
a traditional attract sequence with call-to-action. (2) Passers-by
often notice inter- activity late and have to walk back to interact
(the landing effect). (3) If somebody is already interacting, others
begin interaction behind the ones already interacting, forming
multiple rows (the honeypot effect).
