Apparently Tokyo iPhone application developers, Ubiquitous Entertainment has come up with a prototype iPhone navigation system which mounts on a standard cycle helmet and helps cyclists get to their destination and is called iPhone Arider.
The prototype runs on an original application which also utilises the iPhone compass along with GPS maps, and can also receive push notifications from Twitter or even phone calls with A2DP.
We have a video showing the iPhone Arider prototype in action courtesy of makezine, which can be viewed below, and looks actually quite interesting, so check it out.
