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 26):
A method for eye tracking calibration comprising:\n under control of a hardware processor: identifying a target region in an environment of a user; identifying a virtual reticle at a position in a rig space associated with a 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; updating the position of the virtual reticle relative to the target region based at least partly on the user's current head pose; determining whether the virtual reticle aligns with the target region; and in response to a determination that the virtual reticle aligns with the target region, providing an indication that an alignment has been achieved.
