Abstract:
Disclosed herein are techniques for eye tracking in near-eye display devices. In some embodiments, an illuminator for eye tracking is provided. The illuminator includes a light source configured to be positioned within a field of view of an eye of a user; a first reflector configured to shadow the light source from a field of view of a camera; and a second reflector configured to receive light from the light source that is reflected by the eye of the user, and to direct the light toward the camera.
