Abstract
A method for calibrating an orientation of an eye-mounted display relative to a user's gaze, preferably performed by a system. The system causes the eye-mounted display to project a calibration image onto the user's retina. The user provides information about a relative orientation between the user's gaze and the calibration image, for example a translation offset or a relative rotation. Based on the received information, an orientation for the eye-mounted display that aligns with the user's gaze is determined. Images to be projected by the eye-mounted display onto the user's retina can be adjusted based on the determined orientation.
Claims21
A method for a user to self-calibrate an orientation of an eye-mounted display relative to the user's gaze, where the user's gaze is a frame of reference of the user's perception of an external environment defined with respect to a field of view of the user's eye, the method implemented on a system and comprising:
- causing the eye-mounted display to project a calibration image onto a user's retina, where the eye-mounted display moves with the user's eye so that the calibration image is projected to a same location within the user's gaze as the user's eye moves;
- receiving information from the user about a relative orientation between the user's gaze and the calibration image within the user's gaze;
- and
- based on the information received from the user and independent of an external optical measurement of the user's eye, determining an adjusted orientation for the eye-mounted display that aligns images projected by the eye-mounted display with the user's gaze.
A non-transitory computer-readable storage medium storing executable program instructions for a user to self-calibrate an orientation of an eye-mounted display relative to the user's gaze, where the user's gaze is a frame of reference of the user's perception of an external environment defined with respect to a field of view of the user's eye, the instructions executable by a system and causing the system to perform a method comprising:
- causing the eye-mounted display to project a calibration image onto a user's retina, where the eye-mounted display moves with the user's eye so that the calibration image is projected to a same location within the user's gaze as the user's eye moves;
- receiving information from the user about a relative orientation between the user's gaze and the calibration image within the user's gaze;
- and
- based on the information received from the user and independent of an external optical measurement of the user's eye, determining an adjusted orientation for the eye-mounted display that aligns images projected by the eye-mounted display with the user's gaze.
An auto-calibrating eye-mounted display system for a user to self-calibrate an orientation of an eye-mounted display relative to the user's gaze, where the user's gaze is a frame of reference of the user's perception of an external environment defined with respect to a field of view of the user's eye, the system comprising:
- an eye-mounted display that projects images onto a user's retina;
- and
- a system in communication with the eye-mounted display, the system executing a method comprising:
- causing the eye-mounted display to project a calibration image onto a user's retina, where the eye-mounted display moves with the user's eye so that the calibration image is projected to a same location within the user's gaze as the user's eye moves;
- receiving information from the user about a relative orientation between the user's gaze and the calibration image within the user's gaze;
- and
- based on the information received from the user and independent of an external optical measurement of the user's eye, determining an adjusted orientation for the eye-mounted display that aligns images projected by the eye-mounted display with the user's gaze.
