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.
Claims14
A head-up display device for creating a display image in front of a vehicle's windshield by reflecting an image at an inner side of the windshield, said head-up display device comprising:
- a display unit for emitting display light corresponding to images representing control switches installed in a vehicle;
- an optical reflector for reflecting said display light emitted by said display unit;
- a touch detection sensor for detecting user touch on said control switches;
- and
- display control means for controlling said display unit to:
- (1) emit only display light corresponding to images representing a specified one of said control switches and related control switches associated with said specified control switch when said touch detection sensor detects user touch on said specified control switch, (2) highlight the image representing said specified control switch in contrast to the images representing said related control switches using a highlight pattern when said touch detection sensor detects the user touch on said specified control switch, and (3) further highlight the image representing said specified control switch in contrast to the images representing said related control switches using a second highlight pattern when said specified control switch is actuated by the user after the user touch.
A head-up display device for creating a display image in front of a vehicle's windshield by reflecting an image at an inner side of the windshield, said head-up display device comprising:
- a display unit for emitting display light corresponding to images representing control switches installed in a vehicle;
- an optical reflector for reflecting said display light emitted by said display unit;
- a touch detection sensor for detecting user touch on said control switches;
- and
- display control means for controlling said display unit to:
- (1) emit only display light corresponding to images representing a specified one of said control switches and related control switches associated with said specified control switch and (2) highlight the image representing said specified control switch by enlarging the image representing said specified control switch in contrast to the images representing said related control switches when said touch detection sensor detects the user touch on said specified control switch.
A head-up display device for creating a display image in front of a glass medium of a movable body by reflecting an image at the glass medium, said head-up display device comprising:
- a display unit for emitting display light corresponding to images representing information relating to said movable body;
- an optical reflector for reflecting said display light emitted by said display unit;
- detection sensors for detecting changes in said information;
- and
- display control means for controlling said display unit to:
- (1) emit only display light corresponding to images representing specified information relating to said movable body and associated information related to said specified information, (2) highlight the image representing said specified information in contrast to the images representing said associated information using a highlight pattern when said detection sensors detect an instruction to change said specified information, and (3) further highlight the image representing said specified information in contrast to the images representing said associated information using a second highlight pattern when said specified information is changed.
