Abstract
A method for determining if a user's gaze is directed in the direction of a zone of interest in a 3D scene comprises: 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.

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.
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.
