"Welcome to the future, where your body is technology's new frontier.
The sensors and computing power we've become accustomed to in our smartphones are starting to migrate to body-worn devices used for new purposes.
Google has stoked excitement for the category after teasing its forthcoming Project Glass headset, but it already faces competition from Vuzix which has been showing off its own Android-powered eyewear at this year's Consumer Electronics Show (CES) in Las Vegas.
The lightweight kit places a tiny widescreen colour monitor in front of the user's right eye so that it appears to hover towards the top of their field of vision. Users control it by pressing buttons placed close to their ear, or via a smartphone paired via Bluetooth.
Initial features are set to include the ability to stream and record video - but the US company's boss suggests developers will soon exploit the hardware for other uses."
