Abstract: Communication channels among users in a collaborative computing system are automatically adjusted based on users' current states detected by various sensing devices. The collaboration system that includes an awareness system for evaluating, monitoring, and controlling, in real-time, the collaboration environment by having events and occurrences with properties. The awareness monitoring system includes (1) receiving and analyzing real time data from input sensors and (2) an elastic spring energy model for automatically adjusting a distance according to a level of privacy desired by individual users, the requirement of the organization, and a need of the collaborative project to have some shared information about individual user activities. When a spring energy model is difficult to obtain, a matrix looks up model is used to automatically adjust a distance according to a level of privacy desired by individual users, the requirement of the organization, and the need of the collaborative project.

Abstract: A video surface is constructed by adjoining a large number of flat screen display devices together. Each screen on this surface is controlled by its own computer processor and these processors are networked together. Superimposed over this surface is a tiling of transparent touch-sensitive screens which allow for user input. The resulting display is thin, has a very high resolution, appears to be a single large screen to the user, and is capable of supporting many different types of human-machine interaction.
