The Virtuality Continuum is a phrase used to describe a concept that there is a continuous scale ranging between the completely virtual, a Virtual Reality (VR), and the completely real: Reality. The reality-virtuality continuum therefore encompasses all possible variations and compositions of real and virtual objects. It has been somewhat incorrectly described as a concept in new media and computer science, when in fact it could belong closer to anthropology.
The concept was first introduced by industrial engineer Paul Milgram of the University of Toronto. The area between the two extremes, where both the real and the virtual are mixed, is the so-called Mixed reality. This in turn is said to consist of both Augmented Reality (AR), where the virtual augments the real, and Augmented virtuality, where the real augments the virtual.
