Abstract
A system and a method for determining a gaze direction of a user viewing a scene is provided. The system comprises a camera for obtaining an image of at least one of the user's eyes, a depth information detection device for obtaining depth data related to the image, and a processing unit. The processing unit is configured to define a surface at a predetermined position relative to the user's eye based on the depth data, obtain a normalized image by projecting the image onto the surface and determine a normalized gaze direction based on the normalized image. The processing unit is further configured to determine a gaze direction based on the normalized gaze direction and the depth data.
