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.

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

A head-mounted display device for providing augmented reality contents to a wearer includes a light projector, and eye tracker, and a beam steerer. The light projector is configured to project light for rendering images based at least on the augmented reality contents. The eye tracker is configured to determine a position of a pupil of an eye of the wearer. The beam steerer is configured to change a direction of the light from the light projector based on the position of the pupil.

Augmented reality head-mounted display with eye tracking for pupil steering

The disclosed system may include (1) a light source that generates light for an image, (2) an optical subsystem that (a) receives the generated light from the light source, and (b) generates, based on the received light, converging light defining an exit pupil that includes the image, where the exit pupil is smaller than a pupil of an eye of a viewer, and (3) a control subsystem that controls at least one of the light source or the optical subsystem to reduce aberration of the image that is caused by the eye of the viewer. Various other methods, systems, and computer-readable media are also disclosed.
