ABSTRACT:
A detector captures one or more images of the face, eyes, or pupils of a person using light propagating at two or more angles of incidence with respect to the optical axis of the detector. A difference image is then generated by subtracting one image from another image. A computed location associated with the pupils in the difference image is then compared with a reference location to determine the gaze direction of the pupils.
