The definition of augmented reality is: a composite view of the user’s real world, that features a superimposed computer-generated image.

The real world environment features images that have been computer generated and added.

A popular example of augmented reality would be the game, Pokemon Go.

A device is needed to view augmented reality.  The tech device must have a camera, typically a smart phone or iPad and can be viewed by holding up and looking at the screen. Augmented reality headsets are used as well.
