Abstract:

The fast development of information technology, which to a large extent deals intensively with human communication, requires a means to integrate gestures into man machine communication. The available CPU power of current computers as well as low cost video devices provide the facilities for tracking human motion by analysis of camera images [5]. In a video tracking environment benefits of mapping freely human gestures to sound and music parameters are often combined with the drawback of a limited feedback to the user. In the case of hand gestures tracked by a video system, a precise positioning of the hand in the gestural space is difficult through the varying biomotor features of different gestures. In this paper two approaches are proposed for providing a performer with haptic feedback of the hand position whereby the gestural space of the hand is divided in radial and concentric sectors. Two approaches are proposed: a tactile feedback through vibrating actuators and audio feedback through different sound generators.
