Abstract
System and method for tracking the gaze of the human eye are described which comprise directing an infrared light beam along an optical axis into the eye, and displaying the reflected optical light distribution on a position sensing detector to determine eye position, considering the differences in infrared reflectivities between the pupil and the surrounding iris and sclera.
