Augmented reality is the next big step for personal computing. Adding information overlays for life has a lot of practical applications, especially if you can avoid fiddling with your device while on the road. And now we can say "there's an app for that."
I think the demo video was a bad way to represent the hud possibly. Maybe if it was shown on a proper road or motorways with intersections, different lanes, exit lanes, roundabouts and at a speed suitable for the road as per signage we may have had a better representation.
HUD has been available in several GM vehicles since the 90's; while this certainly would be more useful incorporating Navigation its not to the point where its distracting from your normal driving any more so than looking at your cluster or dedicated gps would. I fell in love with Hud in my 98 Bonneville and will not havea car without it. (its easy enough to add LoL)
I don't see this going very far. All you really need is a reflective sticker on the windshield, available from just about all windshield replacement shops (the GM's with HUD have a reflective layer built into the windshield which most replacements don't have - hence the need for the sticker) and a display driver to reverse the display image. Google Navigation already has a black & white type mode which is the one I prefer anyways.
Can you people See an realized that he is in a Rally cruise ?
he isn't driving off road. He is driving in the proper way you should drive on that kind of track at that speed. If you don't drive like that on those terrains, you will be flipping your car back to it 4 wheels 90% of the time.
Cool idea, but limited to screen size of the tablet, would be better if the whole dash was projecting to give a whole windscreen HUD, so made for the car would be better. By all means have the app on a phone or tablet you plug into a USB port in the car.
