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.
