Patent abstract

A system and method of adaptively establishing fixation thresholds for eye-gaze tracking data and identifying fixations within the eye-gaze tracking data are disclosed. Eye-gaze tracking data is collected. A saccade estimate may be calculated using a percentile statistic of the changes in eye-gaze position. Fixations may be determined by comparing the saccade estimates with the changes in eye-gaze positions over time windows.
