Abstract
A method for determining a viewing direction of a person, such as a driver in a motor vehicle, is provided.

Claims7
A method for determining a viewing direction of a person in a motor vehicle, the method comprising the acts of:
- recording, by a camera, a head region of the person in the motor vehicle;
- detecting a position of a head of the person based on said recording of the head region;
- detecting an eye position of the person based on the detected position of the head of the person;
- providing the detected eye position to a depth sensor;
- acquiring, by the depth sensor, a surface contour of a surface of an eye of the person based on the detected eye position;
- detecting a normal vector on the surface of the eye as a function of the acquired surface contour;
- and
- determining the viewing direction of the person as a function of the normal vector.
