Google Glasses

Six months after their spectacular unveil, Google is about to send the first round of augmented reality Google Glass devices to developers. Developers will pay $1,500 for the privilege of receiving an early, prototype version of Google Glass, but the polished consumer version — due in 2014 — should be a lot cheaper.
As it stands, Google Glass is a browband — like a pair of spectacles, but without the lenses — with what basically amounts to small ARM computer running Android attached to the right side, by your temple, and a large battery behind your right ear. There’s all the usual hardware that you would find in an Android smartphone — a speaker (near your ear), a forward facing camera, gyroscope, accelerometer, compass, a couple of microphones, and WiFi and Bluetooth aerials — but instead of a large touchscreen, there’s a tiny display placed near your right eye.
