GPS devices are great, but you always have to look at them and their screens to see where you should be headed. That's not the case with this pair of glasses created by the Nakajima Lab at the University of Electro-Communications in Tokyo.

The glasses are equipped with a battery, LEDs, a microcomputer, and a magnetic direction sensor. These interact with a portable mini-computer which detects the user's current location using GPS. The magnetic sensor detects which way the wearer is facing, and then the LEDs light up either in green or red, depending on whether or not they're facing in the right direction.

Sure, it's a little primitive and not something you'd want to use every day, but it's clearly a first step towards something a little more user-friendly. And that means never getting lost again.
