A display as big as your windscreen.
Augmented Reality May Become a Reality by 2016 .
Displaying navigation information on car windshields may become reality in less than a decade.
If thin, transparent and curved display panels could be attached to a windscreen, drivers would be able to see navigation information displayed there.
There are challenges to this application, namely cost and durability. The inside surface of a windscreen (surface 4) takes abuse, such as parking stickers. This has been the main factoring for not using polycarbonate as the inner layer. Previously HUD worked with aid of a wedged Poly Vinyl Butyral (PVB). Now it looks like that may change. Head-up displays make driver and vehicle information easily accessible by projecting it onto the windshield just below the driver´s line of sight.
