Real-Time Gaze Tracking With A Single Camera

This paper presents a non-intrusive method for gaze tracking, using a single monocular low-resolution camera. By tracking the face orientation and the center of the pupil, the system estimates the gaze direction which can be projected onto a screen to obtain the user's point of gaze. As the design is based on open source portable building blocks, the system can be used on a variety of devices. The implemented gaze tracker achieves real-time performance. Although the measured accuracy does not compete with other expensive, more complex solutions, it is still possible to integrate it into other applications which require basic gaze tracking capabilities.
