Augmented reality
Augmented reality (AR) is an interactive experience of a real-world environment where the objects that reside in the real world are enhanced by computer-generated perceptual information, sometimes across multiple sensory modalities, including visual, auditory, haptic, somatosensory and olfactory.


- AR : can be defined as a system that incorporates three basic features: a combination of real and virtual worlds, real-time interaction, and accurate 3D registration of virtual and real objects
- The overlaid sensory information : can be constructive (i.e. additive to the natural environment), or destructive (i.e. masking of the natural environment).
- His Experience : is seamlessly interwoven with the physical world such that it is perceived as an immersive aspect of the real environment.
- Two largely synonymous terms : mixed reality and computer-mediated reality.
