1. A mobile device for detecting user input on a display, the mobile device comprising:
- a hand-held display unit comprising;
a display having an electromagnetic radiation detector is configured to detect an electromagnetic radiation profile responsive to a position of a user input object when the position of the user input object is spaced apart from the display; and
a controller configured to identify a user input from the electromagnetic radiation profile;
wherein the display further comprises an electromagnetic radiation emitter configured to emit electromagnet radiation in a direction away from the display, and the electromagnetic radiation detector is configured to detect electromagnetic radiation reflected from a user input object in a direction toward the display, wherein the electromagnetic radiation detector comprises a first electromagnetic radiation detector, the display further comprising an electromagnetic radiation emitter, a second electromagnetic radiation detector, and a refractive medium, wherein the electromagnetic radiation emitter is configured to emit electromagnetic radiation in a direction toward the refractive medium, and the refractive medium is configured to reflect electromagnetic radiation in a direction toward the second electromagnet radiation detector, the refractive medium being further configured to change a direction of reflected electromagnetic radiation responsive to contact from a user input object, wherein the controller is further configured to identify a user input responsive to an amount of electromagnetic radiation detected by the second electromagnetic radiation detector.
