Abstract. As virtual reality evolves towards more natural interfaces, new contact less interaction based on gesture recognition is unfolding. This interaction is supported on geometric, dynamic and cognitive modelling of gestures. As well as other branches of arti cial intelligence, computer vision plays an important role in this modelling. The purpose of this paper is to describe how computer vision is helping to develop virtual reality and present someinterfaces developed in our laboratory
