Eye tracking for pupil steering in head-mounted displays using eye tracking sensors

A method for providing augmented reality contents to a wearer using a head-mounted display device that includes an eye tracking sensor, a light projector, a beam steerer, and a combiner includes determining, with the eye tracking sensor, a position of a pupil of an eye of the wearer. The method also includes projecting, with the light projector, light for rendering images based at least on the augmented reality contents, and changing, with the beam steerer, a direction of the light from the light projector based on the position of the pupil. The light from the beam steerer is directed toward the combiner and the light from the beam steerer and light from an outside of the head-mounted display device are combined, by the combiner, to provide an overlap of a rendered image and a real image that corresponds to the light from the outside of the head-mounted display device.
