Weak Signal's description 
According to a 16 May 2013 review in The Telegraph, Google Glass is "the computer that has both excited and worried millions. Forget the next iPad or the Samsung Galaxy S5 - Google Glass is the hottest property in today’s overheated world of technology, despite the fact that almost nobody who is talking about it has yet worn one and they’re a year away from going on sale. So what is it really like to use? Is it recording everybody’s every move? Is it selling your soul to Google? Glass is a wearable computer the like of which we have never really seen before. While police and the military developed cameras that can record and send images, Glass is fundamentally a product of the web. It consists simply of a screen, sitting above the wearer’s right eye, that looks to them like a 25” display just inside their peripheral vision, a battery, and a panel that allows users to swipe through what is displayed on that screen". Its cost is estimated at $1,500 (not currently available to the public).
