A display system includes an image generator configured to generate a virtual image and a first beam splitter coupled to the image generator. The virtual image and a real-world view are viewable through the first beam splitter from a viewing location. The display system also includes a second beam splitter coupled to the first beam splitter and a camera coupled to the second beam splitter. The camera is configured to image an eye of a user located at the viewing location. Further, a controller is coupled to the image generator and the camera. The controller is configured to process the image of the eye of the user, to determine a location in at least one of the real-world view and the virtual image where the eye of the user is focused, and to control an operation of the display system in response to the determined location.
