Google now has a prototype called ‘project glass’ which is basically a set of glasses to provide this augmented reality. They have created the following video to demonstrate the concept:

Now of course this video is the ‘rose coloured glasses’ through which Google would like us to believe it will be like. If it is from Google then it is probably going to look more like this video:
