Title: Tele-Immersion, The Cyber-Infrastructure for Studying Body Language

Abstract:
The tele-immersion system at CITRIS lab at UC Berkeley consists of 48 cameras in 12 stereo clusters. Images are processed by 12 computers running simultaneously and sending data via Internet II connection to near and remote rendering computers. This system enables to generate in real time (22 frames/second) 4D data of moving people. In this presentation I will show the following applications:

* Two dancers each in separate locations dancing together in the Virtual space;

* Two Geo-scientists in different locations discussing, manipulating and analyzing seismographic data interactively;

* Archeologist analyzing 3D data from China virtually.

The scientific agenda stemming from this infrastructure is the dynamic analysis of Human body action and its interpretation. We will show some preliminary results from segmentation and classification of human action. This work is collaboration between UC Berkeley, UIUC, UC Merced and UC Davis.
