Augmented reality (AR) is a term for a live direct or indirect view of a physical real-world environment whose elements are augmented by virtual computer-generated imagery. It is related to a more general concept called mediated reality in which a view of reality is modified by a computer. As a result, the technology functions by enhancing one’s current perception of reality.
AR is the stuff of Sci Fi, but it is here with us now with companies like Layar, Total immersion and others. It is becoming increasingly popular. My friends in media and advertising love the cool technology with cyborg fantasies of playing ‘terminator’!
