WINDOW OPENS UP THE WORLD
OUR windscreen could soon read road signs, guide you through thick fog and show you where to go.
GM this week revealed it is working on the nextgeneration head-up display which uses the entire windscreen as a transparent display.
Present head-up display, such as that featured in upmarket BMWs, is limited to small screens directly in front of the driver.
The screen GM has developed at its Michigan global research and development centre has a phosphor coating which reacts when a small laser projects information on it, creating different colours.
GM lab manager Thomas Seder explained the safety benefits in the technology at the launch.
‘‘Let’s say you’re driving in fog; we could use the vehicle’s infrared cameras to identify where the edge of the road is and the lasers could paint the edge of the road on to the windshield so the driver knows where the edge of the road is,’’ he said.
GM is working with Carnegie Mellon University and The University of Southern California to de-
Yvelop the system ahead of its production debut in 2016.
Holden external communications director Emily Perry said the headup display development is ‘‘a really exciting project that has generated lots of interest in Australia as well’’.
‘‘At Holden we look at all technologies that GM has to offer, particularly when it comes to improving road safety,’’ she said.
‘‘It is currently an advanced engineering project so we can’t comment on how or where it would be rolled out first, but in time, should the system be commercialised, it could be a huge step forward in making driving safer for Australian motorists and pedestrians.’’
The head-up windscreen is expect to feature an evolution of GM’s road sign recognition system that tells the driver the speed limit.
It would be expanded to alert the driver to speed limits with a laser drawing a ring around the sign.
The system is also expected to be linked to the satnav to alert the driver of their desired exit by reading traffic signs.
