Abstract: A multi-mode eye-tracking system allows independent control of a set of illuminators while providing accurate calculations of both corneal reflections and pupil centers. One illumination mode includes alternating back and forth between a pair of illuminators during successive time segments, then activating both illuminators after a predetermined time interval. One eye-tracking mode includes alternating back and forth between a pair of illuminators during successive time segments, but selecting a single illuminator for activation during successive time segments in the event that a previous computation was unsatisfactory for a given illuminator. One illumination mode includes activating a single illuminator based on the lateral position of the gaze point on the display.
