In this paper we describe real-time 3D video technology for immersive telepresence applications.The technology allows users to meet and collaborate in networked virtual environments in full 3D.The user can freely navigate and see himself or others from arbitrary viewing points.The photorealistic appearance of a 3D user representation allows for natural collaboration in immersive spaces and enables novel interaction techniques for telepresence.Besides interacting with the environment a user can also interact with 3D representations of himself and of remote users.To this end, we identify a design space to show how blue-c differs from current telecollaboration systems.The main contribution is 3D video as an interaction medium for immersive projection and 3D video acquisition environments.We conclude with some experiences derived from inserting and interacting with 3D representations of the users in specific virtual reality applications.
