A non-contact mouse for surgeon-computer interaction

Abstract

We have developed a system that uses computer vision to replace standard computer mouse functions with hand gestures. The system is designed to enable noncontact human-computer interaction (HCI), so that surgeons will be able to make more effective use of computers during surgery. In this paper, we begin by discussing the need for non-contact computer interfaces in the operating room. We then describe the design of our non-contact mouse system, focusing on the techniques used for hand detection, tracking, and gesture recognition. Finally, we present preliminary results from testing and planned future work.
