Head-up display sat-nav by Harman

Integrated sat-navs have to date relied on computer-generated images (CGI) on a dashboard screen to show drivers a route. But not for much longer. Technology firm Harman has developed a system that projects the picture on to the base of the car'€™s windscreen.

So-called '€˜head-up displays'€™ are reasonably common in luxury cars now, but only show very basic sat-nav instructions. Harman'€™s innovation features '€˜augmented reality'€™, a CGI that reacts in real time to the road ahead. So if you need to take a particularly motorway exit, the image shown on the windscreen is superimposed over where you need to go, and adapts as you get closer. It will be seen on production cars within two years.
