An Immersive Bidirectional System for Life-size 3D Communication

Abstract

Telecommunication and video conferencing are an integral part of modern society with implications in many aspects of everyday life. However, compared to a meeting in person, the sense of presence is still limited in electronic communication. In this paper, we present a novel system for life-size 3D telecommunication. It is designed to create an immersive user experience by seamlessly embedding a remote conversation partner into the local environment. To achieve this, users are captured in 3D by hybrid (color+depth) sensors and displayed on a life-size transparent 3D display. We have built two instances of this system in Zurich and Singapore. They form a complete and fully functional prototype enabling bidirectional communication in real-time over a long distance. We further demonstrate alternative hardware setups, which make our system flexible and adaptable to different usage scenarios.
