1. A method comprising:
for each simulated eyeball of one or more simulated eyeballs of an oculomotor simulator:
receiving instructions specifying movement for the simulated eyeball;
enabling movement of the simulated eyeball based on the received instructions; and
obtaining a ground-truth value for three-dimensional (3D) gaze of the simulated eyeball during the specified movement; and
determining accuracy of an eye-tracking device, the determined accuracy based on received values for the 3D gaze of the simulated eyeballs from the eye-tracking device performing eye-tracking of the simulated eyeballs during the specified movement and the obtained ground-truth values for the simulated eyeballs.
