Abstract: An eye-mounted display can be calibrated relative to a user's gaze. A calibration system causes the eye-mounted display to project a calibration image onto the user's retina. The system detects eye movement as the user looks towards the calibration image. Once the detected eye movement indicates that the user's gaze is centered gaze on the calibration image, the system determines a calibration parameter representative of the user's gaze or the detected eye movement. The calibration parameter can be, for example, a pixel offset relative to an initial image source location or an image source pixel corresponding to the user's centered gaze. Subsequent images are then projected by the eye-mounted display onto the user's retina based on the calibration parameter.
