… a journey to the near future

…a glimpse of one possible destination, as seen by an artist in 1997

Medical applications: - tele-diagnostics - tele-assisted surgery - advanced surgical training - preoperative planning Other: - tele-meetings - tele-collaborative design - computer supported training and education - 3D interactive video - entertainment

…May 2000, before submission of this presentation :

…soon after, in October 2000 :

Hardware and software technologies needed: -3D real-time system for acquisition of dynamic, real objects (Upenn) -static scene acquisition (UNC) -rendering and stereo display architecture (UNC) -high precision headtracking system (UNC) -modeling and manipulation with virtual objects (Brown) -multi-person interaction and collaborative architecture (Brown)
