In this paper we have presented some preliminary results with detection and tracking of fingers and faces. We have also experimented with eyetracking using snakes and other techniques based on signal processing, as well as face interpretation using EigenFaces [TP91]. It is increasingly apparent that computer vision has the potential to provide a rich new source of interaction modes for computer human interaction. Vision can make the machine ``aware'' of the user, his movements and environment, in ways that are yet to be invented.
