ABSTRACT:
A head-up display device includes a display unit for emitting display light corresponding to images of control switches, and an optical reflector for reflecting display light. A windshield or a combiner installed on the windshield reflects the image before creating a display image in front of the windshield. The head-up display device has touch sensors on control switches mounted inside a vehicle. When these touch sensors detect user contact on a control switch, the display unit displays the touched control switch and related switches together with highlighting the same control switch in comparison with its related switches.
