Abstract

Teleimmersion is an emerging technology that enables users to collaborate remotely by generating realistic 3D avatars in real time and rendering them inside a shared virtual space. The teleimmersive environment thus provides a venue for collaborative work on 3D data such as medical imaging, scientific data and models, archaeological datasets, architectural or mechanical designs, remote training (e.g., oil rigs, military applications), and remote teaching of physical activities (e.g., rehabilitation, dance). In this paper, we present our research work performed over the course of several years in developing the teleimmersive technology using image-based stereo and more recently Kinect. We outline the issues pertaining to the capture, transmission, rendering, and interaction. We describe several applications where we have explored the use of the 3D teleimmersion for remote interaction and collaboration among professional and scientific users. We believe the presented findings are relevant for future developers in teleimmersion and apply across various 3D video capturing technologies.
