Abstract
A display device comprises a display screen, a graphical user interface navigation button and a proximity sensor including an infrared radiation emitter, an infrared radiation sensor and an infrared radiation source differentiator. The infrared radiation emitter emits a navigation infrared radiation. The infrared radiation sensor is positioned relative to the infrared radiation emitter to sense a reflection of the navigation infrared radiation in a navigation direction corresponding to the infrared radiation sensor. The infrared radiation source differentiator is in electrical communication with the infrared radiation sensor to provide a navigation mode signal indicative of at least one of a sensing by the infrared radiation sensor of a reflection of the navigation infrared radiation in the navigation direction corresponding to the infrared radiation sensor by a navigation object proximate the infrared radiation emitter and the infrared radiation sensor, and a sensing by the infrared radiation sensor of ambient infrared radiation emitted by an infrared radiation source other than the infrared radiation sensor.
