What is Augmented What is Augmented Reality?Reality?

Augmented reality (AR) is a field of computer Augmented reality (AR) is a field of computer research which deals with the combination of research which deals with the combination of real-world and computer-generated data.real-world and computer-generated data.

In this presentation, we will take a look at this In this presentation, we will take a look at this future technology, its components and how it future technology, its components and how it will be used. will be used.

Milgram coined the term “Augmented Milgram coined the term “Augmented Virtuality” to identify systems which are Virtuality” to identify systems which are mostly synthetic with some real world mostly synthetic with some real world imagery added such as texture mapping imagery added such as texture mapping video onto virtual objects.video onto virtual objects.
