A wearable system for eye tracking calibration comprising: an image capture device configured to capture eye images of one or two eyes of a the user of the wearable system ; a display system configured to be worn on the head of the user, and configured to render a virtual eye calibration target and a virtual reticle ; and a hardware processor programmed to: cause the display system to render the virtual eye calibration target at a fixed location within the user's environment; determine a relative location of the user to the virtual eye calibration target ; determine, based on the relative location, a size of the virtual reticle ; cause the display system to render the virtual reticle having the determined size; calculate a position of the virtual reticle with respect to the virtual eye calibration target, based on a current head pose of the user; determine, based at least partly on the position of the virtual reticle with respect to the virtual eye calibration target , whether the virtual reticle aligns with the virtual eye calibration target ; and in response to a determination that the virtual reticle aligns with the virtual eye calibration target , instruct the image capture device to capture eye images for the eye tracking calibration. an image capture device configured to capture eye images of one or two eyes of a the user of the wearable system ; a display system configured to be worn on the head of the user, and configured to render a virtual eye calibration target and a virtual reticle ; and a hardware processor programmed to: cause the display system to render the virtual eye calibration target at a fixed location within the user's environment; determine a relative location of the user to the virtual eye calibration target ; determine, based on the relative location, a size of the virtual reticle ; cause the display system to render the virtual reticle having the determined size; calculate a position of the virtual reticle with respect to the virtual eye calibration target, based on a current head pose of the user; determine, based at least partly on the position of the virtual reticle with respect to the virtual eye calibration target , whether the virtual reticle aligns with the virtual eye calibration target ; and in response to a determination that the virtual reticle aligns with the virtual eye calibration target , instruct the image capture device to capture eye images for the eye tracking calibration. cause the display system to render the virtual eye calibration target at a fixed location within the user's environment; determine a relative location of the user to the virtual eye calibration target ; determine, based on the relative location, a size of the virtual reticle ; cause the display system to render the virtual reticle having the determined size; calculate a position of the virtual reticle with respect to the virtual eye calibration target, based on a current head pose of the user; determine, based at least partly on the position of the virtual reticle with respect to the virtual eye calibration target , whether the virtual reticle aligns with the virtual eye calibration target ; and in response to a determination that the virtual reticle aligns with the virtual eye calibration target , instruct the image capture device to capture eye images for the eye tracking calibration. <EOS>
