This collaborative technology is based on the capability of semi-real time imaging in physical activity of two or three people. We have built a laboratory equipped with 48 cameras in UC Berkeley and 10 cameras in the University of Illinois at Urbana-Champaign. The software accompanying these images reconstructs and displays complete 3D data representing the physical activities of the people in the laboratory. The display is a stereo display so that when viewed through stereo glasses the viewer gets true 3D impressions. We are exploring the connectivity through long distance and planning to examine the effect of what it means to meet in Cyberspace.
