Augmented reality is kind of a hybrid between material reality and virtual reality in that it combines the power of hyperlinks and interconnected media with the geography and architecture of the physical world.

For a long time everyone assumed that virtual reality would be the basis of "cyberspace" and that it's arrival was imminent, however while it has been around from a technical perspective for well over a decade, very few regular folk have adopted it, outside of the gaming world of course.

So augmented reality is appearing as a kind of compromise that brings the benefits and promise of virtual reality to the real world that we all find so comfortable.

As well the rate of technological change is so rapid these days that while this may be the first time you've heard of augmented reality, I anticipate that you'll hear a lot more real soon, and by the end of the year it could be a regular part of the popular culture.
