ABSTRACT:
In a method for detecting, evaluating, and analyzing look sequences of a test person using a look detection system, the field of view of the test person is detected by a first camera, which is directed forwardly and firmly held on the person's head, and recorded in a field of view video. The movement of the pupils is detected by a second camera, also firmly held on the person's head and recorded in an eye video. The pupil coordinates for each frame of the eye video are determined by automatically measuring the contrast of the pupils relative to the surrounding areas with an image recognition program, and the centroid of the dark area, which corresponds to the pupil center having the pupil coordinates is established. A correlation function between pupil coordinates in the eye video and the coordinates of the corresponding visual point is determined in the field of view video. Subsequently, the coordinates of the corresponding visual point in the field of view video are extrapolated from the pupil coordinates for each frame in the eye video.
