Abstract: A retinal projection display system includes at least one visible light source for projecting a visible light image, an infrared light source for projecting infrared light, a scanning mirror having a field of view larger than the visible light image, a reflective surface on which the visible light image is projected and on which the infrared light is reflected at least partially towards an eye of a user, wherein the reflective surface is larger than the visible light image, at least one infrared photodetector for receiving reflected infrared light that reflects off of the eye of the user, and a hardware computation module comprising a processor and a memory, the hardware computation module configured to determine a gaze direction of the user based at least in part on the reflected infrared light.

Abstract: A retinal projection display system includes a light source for projecting an image, a scanning mirror having a field of view larger than the image, and a reflective surface on which the image is projected, wherein the reflective surface is larger than the image. The scanning mirror projects the image onto a viewable region of the reflective surface such that the image is projected into a retina of a user.
