Method and apparatus for evaluating results of gaze detection

摘要

The invention relates to a method and an apparatus for evaluating results of gaze detection, wherein these results are present or are obtained in the form of information which defines, for each of a multiplicity of successive times, a viewing direction detected at this time and a focal point identified thereby in a scene image assigned to this time. For this purpose, the invention provides for the following steps to be carried out: —a temporal change in the viewing direction and/or the focal point is evaluated in order to identify different viewing events which differ from one another by different speeds of an eye movement, wherein saccades and fixations and/or pursuit movements are detected as different types of viewing events and the identified viewing events are classified according to the type thereof, —a period of time spanned by the times is divided into intervals in such a manner that an interval corresponding to a duration of the particular viewing event is assigned to each of the identified viewing events, wherein at least some of these intervals each contain a sequence of a plurality of times, —precisely one of the times or a true subset of the times is selected in each case from each of the intervals assigned to a fixation or a pursuit movement, —and, for each of these selected times, the focal point identified in the scene image assigned to the particular time is mapped to a position corresponding to this focal point in a reference image.
