Abstract
An apparatus for calibrating an eye tracking system of a head mounted display displays a moving object in a scene visible through the head mounted display. The object is displayed progressively at a plurality of different points (P) at corresponding different times (T). While the object is at a first point of the plurality of different points in time, the apparatus determines whether an offset between the point P and an eye gaze point (E) satisfies a threshold. The eye-gaze point (E) corresponds to a point where a user is determined to be gazing by the eye tracking system. If the threshold is not satisfied, the apparatus performs a calibration of the eye tracking system when the object is at a second point of the plurality of different points in time. The apparatus then repeats the determining step when the object is at a third point of the plurality of different points in time.
