Augmented reality (AR) is a research field in computer science that deals with the integration of the real world with virtual elements or computer generated data. Most of the current research in AR is in processing live video stream, which are digitally processed and "amplified" by adding computer generated graphics. Advanced research include tracking moving objects, robust tracker recognition using computer vision, and buidling virtual environments controlled by any number of markers or tracked objects.

There are two widely used definitions for AR. The first is by Ronald Azuma in1997 [1], which say that AR:

  • combines real and virtual
  • is interactive and real time
  • it is processed in 3D

In addition to it, Paul Milgram and Fumio Kishino defined the Milgram's Reality-Virtuality Continuum in 1994 [2]. They describe a continuum that goes from completely real environmentes to completely virtual ones. In the middle is augmented reality (closer to the real environment) and augmented virtuality (closer to the virtual environment).

Recently I have chosen them to <@anchor>write my paper</anchor>. And you know what? They coped with this task very well, although it was not the easiest one. Usually I write my paper on my own, but that time I was in need of professional assistance. So this post is kind of �thank you�. 355–385, August 1997.
