Abstract

This paper introduces a system that enables a presenter to work directly on the projected screen without interrupting the presentation flow by mouse or keyboard use. One uses his fingers as a natural pointing device. The system consists basically of an LED and a webcam as well as a small software system that runs on the presenter's notebook. The camera observes the LED position and the software converts it into mouse events.
