Sat-nav firm Garmin have developed a portable head-up display (HUD) for cars that projects directions onto your vehicle's windscreen.
The portable HUD works with a smartphone and Garmin app to generate navigation information and the company's new HUD gadget projects via the HUD's attached reflector lens on to a transparent film mounted on your windscreen, displaying guidance within your regular line of sight. The simple interface displays your current speed and the speed limit, turn arrows, the distance until your next turn and an ETA.
The navigation system can also provide voice prompts via a smartphone's speaker or a car stereo that works with the Bluetooth short range radio technology. The app associated with the sat-nav system is available for iPhones, Android phones and Windows Phone 8 handsets.
The HUD automatically adjusts brightness levels to ensure that projected information is easy to read during the day and at night.
Tim Edwards, a principal engineer in the future transport technology division at motor industry research firm Mira said, "HUDs that project information on to windscreens can cut down on driver distraction as people spend less time looking down at instruments and more with their eyes on the road." and that "such systems were likely to become more necessary as vehicles got progressively more autonomous because drivers would need to be quickly told if they suddenly needed to take over."
Garmin said its HUD would cost about $130 (£86) when it went on sale in late summer. Regional maps for the associated Garmin app will cost about $30 (£20) each.
What are your thoughts - would you want one in your car? Would it help your driving and put your concetration back onto the road or would you be focusing too much on the small display?
