Abstract
Techniques are provided to determine the horizontal gaze of a person from a video signal generated from viewing the person with at least one video camera. From the video signal, a head region of the person is detected and tracked. The dimensions and location of a sub-region within the head region is also detected and tracked from the video signal. An estimate of the horizontal gaze of the person is computed from a relative position of the sub-region within the head region.
