If you think that navigating the road with external devices while riding a bike is difficult to concentrate, LiveMap Augmented Reality helmet might be your solution. Like Google Glass, it projects a screen on the visor to help you navigate while you concentrate on the actual road conditions.
According to the video, it will be slightly larger than conventional full face helmet and the battery can last a day (you can charge the battery via USB Port).
Check out the video.
At this moment, you will not be able to buy this helmet. The RRP is targeted to be around USD2,000 while early birds will get it at USD1,500.
The LiveMap helmet project is currently gathering funds at Indiegogo.
