A few cars - such as the 2011 Chevrolet Corvette - already use basic systems to ensure the driver keeps his eyes on the road as much as possible, but with improvements in display technology and a move towards augmented reality companies like Pioneer are developing next-generation systems.
Pioneer's Augmented Reality Head-Up-Display (we'll stick with AR-HUD) uses laser projection to display an image on a "clear sunvisor" in front of you in your line of sight.
Information includes navigation tips and speed limit warnings and can even display smartphone-connected information, if required. Since the information is around your line of sight, it's safer than looking down to the center stack or instruments but not vivid enough to distract you from the business of driving.
Pioneer has been working on making the technology compact enough to work in a car. Augmented reality integration means that navigation signals can actually be displayed on the road in front, making finding your way easier than ever. It's not the first time we've seen augmented reality applied to your windshield - Autoglass previewed something similar back in May.
AR-HUD is expected to launch next year according to Expert Reviews, though technology this advanced is unlikely to come cheap...
