Claim:
1. A method for evaluating results of an eye tracking, these results being present or obtained as information which defines, for each of a large number of successive moments, respectively a gaze direction detected at this moment and a consequently identified visual point in a scene image assigned to this moment, the scene images being time-dependent such that the scene images assigned to the different moments are different and the method comprising the following steps: evaluating a temporal change in the gaze direction and/or in the visual point and/or in an eye movement for identifying different visual events, at least two different types of visual events being recognized and the identified visual events being classified according to their type, dividing a period of time comprising the large number of successive moments into intervals such that an interval, which corresponds to a duration of the respective visual event, is assigned to each of the identified visual events, selecting a moment or proper subset of moments from each of the intervals which are assigned to the respective visual event of at least one selected type of visual event, and for the selected moment or proper subset of moments in each of the intervals, determine a location of the visual point identified in the scene image, respective visual points corresponding to the respective visual events of the respective intervals, and map a respective determined location of the respective visual point for the respective selected moment or proper subset of moments in each of the intervals onto a position in a reference image corresponding to the respective determined location of the respective visual point of the interval in the scene image.
