The International Consumer Electronics Show for this year saw one exhibit being visited by nearly all car and technology enthusiasts attending the show: Audi scored major publicity points with their exhibit this year, which showcases the company’s latest development in HUD or heads-up display technology for auto glass, a sleek, rather beautiful contact-analogue HUD that displays all HUD graphics at eye-level and almost as if superimposed on the actual environment that the driver or the front-seat passenger can see through the windshield.
HUDs for auto glass are not entirely new, but the technology has only about two decades or so of application in automobiles. HUDs actually started in the military, most specifically in military aircraft. The name itself comes from the way that aircraft pilots in gunners or dog fighting aircraft typically position their heads, which is described as being “up”—that is, facing straight forward without any downward tilt to the chin. HUD is pretty much par for the course now where airplanes and jets are concerned, and their use in automobile manufacture and design is quite fresh, by comparison.
The first HUDs in cars were from American auto manufacturers, although other countries soon caught up, with more and more production series cars being rolled out with them as a luxury option. The typical information displayed by HUDs would be that which you can find on a regular vehicle’s indicators such as the tachometer and the speedometer, and in some cases, even GPS information for those who need navigational assistance. GPS is actually the most commonly requested or sought out feature of HUD displays, at least for majority of those who want the technology in their cars, although most navigation systems using HUD technologies have been largely described as not-yet-up-to-expectations by most consumers.
The problem, perhaps, is that HUD technology for auto glass has developed far more quickly in the popular imagination and in Hollywood than it has in real life. With countless science fiction movies displaying HUDs with rather unbelievable clarity showing up on “vehicles of the near future” (whenever that might be), most consumers tend to get disappointed when they see the sobering reality of most HUDs, which are still largely simple when compared to those fanciful machines and exhibits at the movies. In fact, most HUDs are still restricted to a fairly curt list of colors, which means they cannot approximate the full-color brilliance and sharpness of movie HUDs.
However, the new Audi auto glass HUD is set to propel real-life technology just that extra bit closer to its fictional counterpart. Boasting of an impressive clarity and color range as well as driver and passenger access (both the driver and passenger can interact with the display and even swipe it towards a center screen for sharing info), this is probably the HUD of tomorrow, and many companies are most likely going to be sitting up and taking notes on how to make their own displays.
