GPS devices are extremely useful things, but having to always keep an eye on the display in order to tell if you’re going in the correct direction might be a tad troublesome. Now the folks over in Japan have come up with a prototype device, dubbed the Wearable Personal Navigation System, which is a GPS-toting pair of glasses that sports integrated LEDs on the frame, and a magnetic direction sensor, detecting the orientation of the user’s head. With that in place, when the user looks in a certain direction, the LEDs will change color in order to notify the user whether that’s the direction you need to head to. Pretty nifty idea, and you can check out a video of this device in action after the jump.
