ABSTRACT:
The inventive method calculates a position of the center of the eyeball as a fixed displacement from an origin of a facial coordinate system established by detection of three points on the face, and computes a vector therefrom to the center of the pupil. The vector and the detected position of the pupil are used to determine the visual axis.
