Current Research

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.
Rich User Embodiment in Groupware
Embodiments are virtual personifications of the user in real-time distributed groupware. Many embodiments in groupware are simple abstract 2D representations such as avatars and telepointers.
