Social Constructionism

Theory of knowledge in sociology and communication theory that examines the development of jointly constructed understandings of the world that form the basis for shared assumptions about reality. The theory centers on the notions that human beings rationalize their experience by creating models of the social world and share and reify these models through language.

Agumented Reality

Direct or indirect live view of a physical, real-world environment whose elements are "augmented" by computer-generated perceptual information, ideally across multiple sensory modalities, including visual, auditory, haptic, somatosensory, and olfactory. The overlaid sensory information can be constructive or destructive and is spatially registered with the physical world such that it is perceived as an immersive aspect of the real environment.

Virtual Reality

The computer-generated simulation of a three-dimensional image or environment that can be interacted with in a seemingly real or physical way by a person using special electronic equipment, such as a helmet with a screen inside or gloves fitted with sensors.
