Abstract
A system includes a curved window and a light energy emitter arranged exterior to the curved window. The system includes a light energy receiver arranged exterior to the curved window and arranged to detect light energy emitted by the light energy emitter. The light energy passes over a touchpad provided on the curved window. A touch on the touchpad may be detected by the system.
Claims18
A system comprising:
- a curved window;
- a light energy emitter arranged exterior to the curved window;
