openEyes is an open-source open-hardware toolkit for low-cost real-time eye tracking.

Visible Spectrum Eye Tracking

This video demostrates ability of the visible starbust eye tracking algorithm. The algorithm tracks the limbus of the eye. The eye image is shown superimposed on the upper left-hand corner of the scene image. The point of gaze is marked as a cross and the best guess limbus ellipse is shown in the eye image.

Infrared Spectrum Eye Tracking

This video demostrates ability of the starbust algorithm to track eye movements even in the presence of significant image noise. The algorithm tracks the pupil and corneal reflection of the infrared illuminator. The eye image is shown superimposed on the upper left-hand corner of the scene image. The point of gaze is marked as a cross and the best guess pupil ellipse is shown in the eye image.
