Current eye tracking and calibration algorithms do not accommodate eccentric viewing and the capacity for accurate eye tracking is difficult to assess in individuals with central visual field loss, and few studies of naturalistic oculomotor behavior exist. To address this problem, we are developing a binocular robotic model of the human eyes that can simulate fixation and eye movements with an eccentric preferred retinal locus in one or both eyes and allow for precise assessment of eye tracking performance of head mounted computer vision-based eye tracking systems.
