15. The device of claim 14 , wherein the controller further determines the user input based on whether the object is a human.
16. A method comprising:
detecting, by at least one location sensor, a location of an object;
detecting, by at least one motion sensor, motion at a virtual input location; and
determining, by a controller, a user input at the virtual input location based at least in part on whether at least a portion of the motion at the virtual input location detected by the motion sensor is at the location of the object detected by the location sensor.
17. The method of claim 16 , wherein the at least one location sensor comprises an infrared sensor.
18. The method of claim 16 , wherein the virtual input location is defined by a three-dimensional space.
19. The method of claim 16 , wherein the at least one motion sensor comprises a camera.
