Abstract
Disclosed herein are devices and methods to determine a gaze associated with an eye. At least one infrared beam may be reflected off of the eye. The reflected infrared beam may be received and reflected from a projection surface that includes one or more layers that reflects infrared light. The projection surface may include a holographic optical element (HOE) that reflects the infrared light. The infrared beam reflected from the projection surface may be received by an infrared light beam receiver. A light intensity associated with the reflected infrared beam may be used to control one or more functionality associated with a projection system.

An apparatus, comprising:
- an infrared light beam emitter to emit at least one infrared light beam;
- and
- an holographic optical element (HOE) to reflect the at least one infrared light beam toward an eye.
A method, comprising:
- emitting at least one infrared light beam;
- and
- reflecting, from a holographic optical element (HOE), the at least one infrared light beam toward an eye.
