Development and application of large interactive display surfaces

Abstract

Recent hardware developments have made possible the construction of relatively inexpensive large interactive display surfaces (LIDS). We have built prototype systems with office whiteboard sized displays using off-the-shelf data projectors and pen digitising equipment. Our group is investigating the use of these prototype systems in a variety of situations, including: programming, teaching, and both local and remote meeting support. The challenge of this research is to provide a style of user interaction in which the computer is an unobtrusive support agent - offering assistance, recording and replaying data - but not distracting from the interaction between people using the system.
