The idea is to the user wears a small single glass lens over an eye, affixed with a transparent screen and a camera, presumably connected via Bluetooth (or some futuristic version of the same) to a phone (or an implant) near the wearer. It’s an idea that has been floating around for decades, but Google’s teaser video on Google+ has confirmed its existence, or at least an intention. There is no working prototype to speak of, other than examples of what the eye-wear could look like, but the idea has been planted, and that’s good enough.
The video shows how the vision glasses works. 
It has the classical Android buttons on the edge, at the back of the head and a camera discretely attached near the lens. It’s a straight design with tubular shapes linked to each other seamlessly. This headset with glasses is able to take pics using an UI similar to the one in Android 4.0 and it also comes with voice command and GPS tracking.
You get Google Maps and the latest emails and Google+ social stats straight to your eyeballs, an interesting feat, as well as the display of the album covers when you listen to music. I wonder how much this invention would impair the user and how much it will affect interacting with the real world… I’m pretty sure Google will reveal something soon concerning their plans for the real Glass project.
