Ubiquitous Interaction Devices
"Building tomorrow's technology on today's hardware"
In recent years, the mobile phone market has grown tremendously,
giving the average consumer access to cheap, small, low-powered and
constantly networked devices that they reliably carry around.
Similarly, laptop computers and PDAs have become a common accessory
for businesses to equip their employees with when on the move.
The Ubiquitous Interaction Devices project seeks innovative
ways to extend these commodity devices to make some of the concepts
in the last decade of ubiquitous computing research a reality
(e.g. context-aware or location-aware interfaces).
Current projects include:
- SpotCode Interfaces take advantage of modern camera-phones,
which offer a programmable interface to allow real-time image processing,
as well as Bluetooth to facilitate local wireless networking. This
project demonstrates how camera phones can be used as a sophisticated pointing
device facilitating interaction with both active and passive displays
in the environment.
- Audio-Networking uses ubiquitously available sound
hardware (i.e, speakers, soundcards and microphones) for low-bandwidth
wireless networking. It has a number of characteristics which
differentiate it from existing wireless technologies:
- It offers fine-grained control over the range of transmission
by adjusting the volume.
- Walls of buildings are typically designed to attenuate sound
waves, making it easy to contain transmission to a single room.
- It allows existing devices that play or record audio to be
networked easily (e.g. voice recorders).
- Computer/Telephone Integration connects a
desktop telephone to a personal computer's soundcard, enabling the PC
to support collaborative applications that react according to what the
user is doing with their phone, and who the user is talking to. An
example application is an audio-conferencing application which augments
a normal teleconference with a visual interface which lists the call
participants, gives cues about the current speaker, and recent history of
