What you see is a full GPS system built into a set of eyeglasses. It’s not an overlay of a map (which would be awesome, no mistake there), but rather a set of LEDs built into the frames that respond to the position of your head, and then light up in the direction you need to go to reach your destination. For instance, if you’re facing north, and need to go south, an LED will light up in the bottom of the lens, showing you that you need to be going the opposite direction you’re going in. A turn to the east, meanwhile, would show up as an LED in the rightmost side of the frame.
There’s no word on pricing or availability, as they’re still under development, but they’re definitely something that would be great for walking tours. Regular GPS systems are often better designed for car dashes than for walking around, and it would be nice to see a pair that’s as easy as slipping on your glasses.
People will be benefited more from this personal navigation systems, they will make traveling easy and fun for all with the pinpoint directional information.
