Automotive head-up display

An automotive head-up display or automotive heads-up display —also known as a auto-HUD— is any transparent display that presents data in the automobile without requiring users to look away from their usual viewpoints. The origin of the name stems from a pilot being able to view information with the head positioned "up" and looking forward, instead of angled down looking at lower instruments. At this time, there are two different approaches to OEM HUDs in automobiles. The first is to treat the back of the windshield in such a way that an image projected onto it will reflect to the driver. The second is to have a small combiner that is separate from the windshield. Combiners can be retracted.

These displays are becoming increasingly available in production cars, and usually offer speedometer, tachometer, and navigation system displays.

Night vision information is also displayed via HUD on certain General Motors, Honda, Toyota and Lexus vehicles. Other manufactures such as Audi, BMW, Citroën, Nissan, Mazda, Kia, Mercedes and Volvo currently offer some form of HUD system.

Motorcycle helmet HUDs are also commercially available.[4]

Add-on HUD systems also exist, projecting the display onto a glass combiner mounted on the windshield. These systems have been marketed to police agencies for use with in-vehicle computers.
