This prototype iPhone nav system mounts on standard bike helmets to help get cyclists where they’re going. Devised by Tokyo iPhone app developers Ubiquitous Entertainment, it runs on an original app that in addition to using the iPhone’s compass and GPS maps can also receive push notifications from Twitter (via TwitBird Pro) or phone calls with A2DP.
The head mounted device (HMD) is retractable, and as you might expect, the screen is a little jiggly during ride. Test cyclist Sho checked out the map while stopped or at traffic lights, not while pedaling. The HMD was so light it was secured with scotch tape; in later trials the iPhone was stuck in a pocket to avoid potential tumbles from the helmet.
As an urban biker sick of pulling out maps or trying to check Google maps on my phone, I love this idea, though I would stick to keeping the phone in a pocket to avoid worry about someone snatching it and the perils of sudden showers.
