We present a real-time camera-based system designed for gaze tracking focused on human-computer communication. We aim to equip computer systems with a tool that provides visual information on the user. This tool must satisfy interaction constraints and be nonintrusive, so we use a CCD camera placed between the keyboard and the screen. The system detects the user’s presence, locates and tracks the face, nose, and eyes. Detection combines image processing and pattern recognition techniques.
