Abstract:
Systems and methods for eye tracking calibration in a wearable system are described. The wearable system can present three-dimensional (3D) virtual content and allow a user to interact with the 3D virtual content using eye gaze. During an eye tracking calibration, the wearable system can validate that a user is indeed looking at a calibration target while the eye tracking data is acquired. The validation may be performed based on data associated with the user's head pose and vestibulo-ocular reflex.

Claim (Index 16):
A method for eye tracking calibration comprising:\n under control of a hardware processor: identifying an eye calibration target in a world space associated with an environment of a user; instructing a wearable device of the user to render a virtual reticle in a rig space associated with the wearable device of the user; obtaining head pose data of the user; determining a current head pose of the user based on the obtained head pose data; determining a relative position of the virtual reticle with respect to the eye calibration target based at least partly on the user's current head pose; determining whether the virtual reticle aligns with the eye calibration target based at least in part on the relative position of the virtual reticle with respect to the eye calibration target; and in response to a determination that the virtual reticle aligns with the eye calibration target, instructing an inward-facing imaging system of the wearable device to acquire eye calibration data.
