Abstract
Examples relating calibrating an estimated gaze location are disclosed. One example method comprises monitoring the estimated gaze location of a viewer using gaze tracking data from a gaze tracking system. Image data for display via a display device is received and, without using input from the viewer, at least one target visual that may attract a gaze of the viewer and a target location of the target visual are identified within the image data. The estimated gaze location of the viewer is compared with the target location of the target visual. An offset vector is calculated based on the estimated gaze location and the target location. The gaze tracking system is calibrated using the offset vector.
