You know what the problem is with most navigation devices? You actually have to look at them, and this fact alone can distract you from the ability to look forward. If you’re tired of bumping into lamp posts, you’ll want to check out this personal navigation system (PNS) from Nakajima Lab. From the University of Electro-Communications in Tokyo, students have devised a set of eyeglasses that feature red and green LEDs. After loading your destination into the mini computer (which I guess you can carry in your backpack), the lights on the glasses will tell you whether you’re heading in the right direction.
That’s because they’re not only programmed in coordination with the GPS, they also have a magnetic sensor to detect which way you are facing. As you walk along the lights will stay green so long as you are heading in the right direction, they’ll turn red when you’re not. This way you don’t have to look at a display, but you are missing out on a ton of information that personal navigation systems usually provide. That and, well, you may look odd with blinking red and green lights by your eyes. Maybe in Harujuku.
