Method and an apparatus for determining a gaze point on a three-dimensional object |
摘要 |
A system for determining the gaze endpoint of a subject, the system comprising:
a eye tracking unit adapted to determine the gaze direction of one or more eyes of the subject;
a head tracking unit adapted to determine the position comprising location and
orientation of the eye tracker with respect to a reference coordinate system;
a 3D Structure representation unit, that uses the 3D structure and position of objects of the scene in the reference coordinate system to provide a 3D structure representation of the scene;
based on the gaze direction, the eye tracker position and the 3D structure representation, calculating the gaze endpoint on an object of the 3D structure representation of the scene or determining the object itself. |
