Demonstration of unified system with 3D real time acquisition data ("real" data), 3D synthetic objects ("virtual" data) and user interactions with 3D objects using virtual laser pointer. The participants in the session are not only able to see each other in 3D but they were able to engage in collaborative work, here a simple example of interior office design.

The remote site in the demo was Advanced Network & Services, Armonk, NY, and local site where images were taken was at the University of North Carolina at Chapell Hill, NC. The data were sent over Internet2 links (Abilene backbone) at the rate of 15-20 Mb/sec (no compression applied).

	System as of Oct 2000 3D real time acquisition data combined with static 3D background and synthetic 3D graphics objects. For the interactive part we used magnetic tracker to mimic virtual laser pointer, as well as a mouse. All synthetic objects were either downloaded or created on the fly. Both users could move objects around the scene and collaborate in design process. Remote participant Amela Sadagic in Armonk NY, and a local participant Wei-Chao Chen in Chapel Hill, NC.

	Bob helps Jaron to create his office. Very soon furniture starts to fly and dance all over the place :) Remote participant Bob Zeleznik (Brown Univ.) was in Armonk NY, and a local participant Jaron Lanier in Chapel Hill, NC. Photo made by UNC.

We demonstrated our proof-of-concept system: 3D tele-immersive system between three remote sites. Two sites acted as acquisition sites (University of Pennsylvania in Philadelphia, PA and Advanced Network and Services in Armonk, NY) and one site had a role of rendering site (University Of North Carolina at Chapel Hill, NC). Each acquisition site was doing local 3D acquisition and sending 3D data over Internet2 (Abilene) at the rate of 3 reconstructions/sec (25-30 Mb/sec), while the reconstruction site was gathering the data, rendering and displaying them on two walls. User sitting at the desk in front of two walls was equipped with a pair of polarized stereo glasses and High-ball headtracker.
