The system described is the Purkinje eye-tracking system. It computes the movements of the pupil's center and utilizes multiple sources of reflection from the eye, including the cornea and the back of the lens, to track eye movements accurately. This method is named after the Czech anatomist Jan Evangelista Purkyně, who discovered the Purkinje images—reflections from structures within the eye.
