	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.
