Claim 12:
13. A system for a head-mounted device for updating an eye tracking model in relation to an eye, wherein the head-mounted device comprises an eye tracking sensor and wherein the eye tracking model relates to a position of the eye tracking sensor and other components of the head-mounted device and a model of each eye, the system comprising a processor, and a memory, said memory containing instructions executable by said processor, whereby said system is operative to:
obtain, by the eye tracking sensor, first sensor data in relation to the eye;
move the eye tracking sensor along an axis parallel to a line bisecting the eyes, wherein the eye tracking sensor is moved after obtaining the first sensor data;
obtain, by the eye tracking sensor, second sensor data in relation to the eye, wherein the second sensor data are obtained after moving the eye tracking sensor; and
update the eye tracking model in relation to the eye, based on the first sensor data and the second sensor data.
