In this paper we address the problem of large-scale video conferencing, both from a systems and user interface point of view. We present the architecture and current implementation of our video conferencing tool, the Digital Amphitheater, which facilitates large scale video conferencing for hundreds of participants in a natural and cohesive environment. We describe a unique user interface that aims to engender a feeling of presence, using background substitution, eliminating control functions from the screen, and allowing participants to view themselves in an amphitheater setting.
