Oculomotor simulator for assessing eye-tracking accuracy

Abstract

A system is described for determining accuracy of an eye-tracking device using an oculomotor simulator assembly. The system receives instructions specifying movement for simulated eyeballs in the oculomotor simulator assembly. The system enables movement of the simulated eyeballs based on the received instructions. The system obtains ground-truth values for three-dimensional gaze directions of the simulated eyeballs in response to the enabled movement using projections of laser diodes from the center of the simulated eyeballs during the specified movement. The system additionally gathers three-dimensional gaze directions as determined by the eye-tracking device that is tracking the simulated eyeballs during the specified movement. The system determines accuracy of the eye-tracking device based on the obtained ground-truth values and the determined three-dimensional gaze directions from the eye-tracking device.
