Body expression in virtual environments

Abstract

As technology improves, virtual reality interfaces based on body actions and expressions are becoming more and more important. In the domain of games, an evident application is the control of the hero by body actions. The robotics domain is another area where such an interface presents an attractive issue, especially in the tele-presence field. In this paper we discuss an action model along with a real-time recognition system and show how it may be used in virtual environments.
