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 1):
A wearable system for eye tracking calibration comprising:\n an image capture device configured to capture eye images of one or two eyes of a user of the wearable system; non-transitory memory configured to store the eye images; a display system through which the user can perceive an eye calibration target in an environment of the user and a virtual reticle; a pose sensor configured to track a head pose of the user; a hardware processor in communication with the non-transitory memory and the display system, the hardware processor programmed to:\n cause the eye calibration target to be perceivable via the display system; \n cause the virtual reticle to be rendered via the display system; \n identify the user's head pose based on data acquired from the pose sensor; \n calculate a position of the virtual reticle based on the user's head pose; \n determine whether the virtual reticle aligns with the eye calibration target based at least partly on the position of the virtual reticle and the eye calibration target; and \n in response to a determination that the virtual reticle aligns with the eye calibration target, instruct the image capture device to capture the eye images and initiate storage of the eye images into the non-transitory memory.
