Abstract
In an embodiment, an apparatus is disclosed that includes at least one processor. The at least one processor is configured to select a light source from a plurality of lights sources based at least in part on a location of a pupil of an eye relative to an eye motion box. The selected light source is configured to illuminate a portion of the eye motion box that corresponds to the location of the pupil with a light beam. The at least one processor is further configured to activate the selected light source to illuminate the portion of the eye motion box.
Claims20
An apparatus comprising at least one processor, the at least one processor being configured to:
- select a light source from a plurality of lights sources based at least in part on a location of a pupil of an eye relative to an eye motion box, the selected light source being configured to illuminate a portion of the eye motion box that corresponds to the location of the pupil with a light beam;
- and
- activate the selected light source to illuminate the portion of the eye motion box.
A method comprising:
- selecting a light source from a plurality of lights sources based at least in part on a location of a pupil of an eye relative to an eye motion box, the selected light source being configured to illuminate a portion of the eye motion box that corresponds to the location of the pupil with a light beam;
- and
- activating the selected light source to illuminate the portion of the eye motion box.
An optical system comprising:
- a plurality of light sources;
- a light-guide optical element comprising a coupling-out arrangement that is configured to direct light beams received from the plurality of light sources toward an eye motion box of the optical system;
- and
- a controller that is configured to:
- select a light source from the plurality of light sources based at least in part on a location of a pupil of an eye relative to the eye motion box, the selected light source being configured to emit a light beam that, when directed by the coupling-out arrangement, illuminates a portion of the eye motion box that corresponds to the location of the pupil;
- and
- activate the selected light source to illuminate the portion of the eye motion box.
