GAZE DETECTION METHOD AND APPARATUS
First Claim
1. A method for determining if a user'"'"'s gaze is directed in the direction of a zone of interest in a 3D scene, the method comprising:
- providing a 3D scene containing a zone of interest;
associating a property with the zone of interest;
creating a bitmap representing the location of the zone of interest in a projected view of the 3D scene, each pixel of the bitmap to which the zone of interest is projected storing the property of the zone of interest;
detecting the direction of the user'"'"'s gaze;
using the bitmap to determine if the detected user'"'"'s gaze is directed in the direction of the zone of interest.

19. An apparatus for determining if a user'"'"'s gaze is directed in the direction of a zone of interest in a 3D scene, the apparatus comprising:
-
a buffer configured to store a bitmap representing the location of a zone of interest in a projected view of a 3D scene, each pixel of the bitmap to which the zone of interest is projected storing a property of the zone of interest; a detector for detecting the direction of the user'"'"'s gaze; a processor for using the bitmap to determine if the gaze detected by the detector is directed in the direction of the zone of interest. - View Dependent Claims (20)
