Augmented reality (AR) is a field of computer research which deals with the combination of real-world and computer-generated data (virtual reality), where computer graphics objects are blended into real footage in real time.

Presently, most AR research is concerned with the use of live video imagery which is digitally processed and “augmented” by the addition of computer-generated graphics. (More from Wikipedia…) This quick guide assumes you have a web cam, printer, and some programming experience.
