We study the effective use of gaze information for human-computer interaction based on a stereo-based vision system which can track the 3-D position and orientation of a user in real-time. We have integrated our face-tracking system into the X Window interface system, and conducted experiments to evaluate the effectiveness of our proposed framework for using gaze information for window interface.
