- a projection apparatus configured to project at least one control element onto a viewing surface of the display element, wherein the viewing surface is on a first side of the display element, wherein the projection apparatus comprises:
- a light source and at least one lens located on a second side of the display element opposite the first side of the display element;
- and
- a reflection surface located on a second, opposite side of the display element;
- and
- a capacitive proximity sensor configured to detect an actuation of the control element,
- wherein the reflection surface is a different surface from the viewing surface and faces the viewing surface, and wherein the reflection surface is configured to receive light beams from the light source and the at least one lens and to reflect reflected light beams from the reflection surface toward the viewing surface and onto the viewing surface.
