摘要
Embodiments of the present invention relate to eyetracking methods and systems that compensate for physiological variations in the location of the pupil within the eye. In one embodiment, a video eyetracker measures the location of a pupil within the eye. Using measured observable features of the eye, including pupil diameter, a pupil-location-offset is estimated with respect to a fixed point on the eyeball. The location of a fixed point within the eyeball is estimated as a function of the measured pupil location and the estimated pupil-location-offset.
