Current Research

Targeting Assistance for Distant Pointing at Interactive Surfaces
Pointing at displays from a distance is becoming a common scenario for controlling computers and entertainment systems.
Interaction Techniques for Digital Tables
Digital tables allow people to interact with computer workspaces that are projected onto tabletops.
Groupware Toolkit for C#
The GT library is a groupware toolkit with two goals: to simplify the development of real-time distributed groupware, and to improve the performance of distributed applications.
