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.
