At the very moment we look at those new clothes in that store window, a special offer for the clothes will flash up on the digital interface of our Google Glass.
Microsoft has announced that it is to make some significant changes to the Windows 8 user interface, including dropping the Aero Glass effect that was first introduced in Windows Vista.
Instead of simply being a phone, he envisioned a tool with no buttons, and a natural user interface that we would interact with using our fingers on smooth glass, as if we were directly touching whatever was displayed on the screen.
Google Glass has transmitters and receivers, cameras, a decent whack of a CPU to run the user interactions and interface, and the nifty screen technology.
