Sure you can put stuff into eyeglasses, however why not put it into smartphones and use eyeglasses as an optional output device?
Wherein Japan Stuffs a GPS System Into a Pair of Eyeglasses – Techland – TIME.com. In this project a GPS system is embedded into a pair of eyeglasses. Awesome!
But, if you take a smartphone like an iPhone which already has a map and GPS system, you can also, using Bluetooth for example, drive the eyeglass LED to provide directional signals for walking or riding things like bicycles.
Not only that, if you really do need more info, the system can detect whether you are really moving or not and then allow you to trigger the Head-Up-Display (HUD) output. Thus, you then have access to a full map and its associated social location-aware applications.
I’m sure this is not a new idea, its in Science Fiction novels and computer games. It is probably also found in hundreds of patents around this “meme” (?). Anyway, my brain read the article and flashed the ‘real’ solution.
