First Claim
Patent Images
1. A method comprising:
- viewing at least a first person with at least a first video camera and producing a video signal therefrom;
detecting and tracking a head region of the first person in the video signal;
detecting and tracking dimensions and location of a sub-region within the head region in the video signal; and
computing an estimate of a horizontal gaze of the first person from a relative position of the sub-region within the head region.

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.
