Google is in full-speed research and development mode with its Project Glass augmented reality eyewear project. When Project Glass was first announced we heralded it as the first step to popularizing wearable computing and Google is hard at work devising ways to make them even more interesting.
A Google patent that has just been published details how a wearable marker, like a ring, a bracelet or even a decal attached to a fingernail may be used to control a head-mounted display (HMD), i.e. Project Glass. The HMD includes an infrared (IR) camera that detects IR radiation reflected from the wearable marker. The wearer can perform different hand gestures, which will then be tracked by the camera and translated to actions. Pretty nifty huh?
