Introduction
The term "metaverse" originated in the 1992 science fiction novel Snow Crash, as a portmanteau of "meta" and "universe". Metaverse development is often linked to advancing virtual reality technology due to increasing demands for immersion.
Definition
In futurism and science fiction, the metaverse is a hypothetical iteration of the Internet as a single, universal and immersive virtual world that is facilitated by the use of virtual reality (VR) and augmented reality (AR) headsets.
What is meant by the term Virtual Reality?
Virtual reality (VR) is a simulated experience that employs pose tracking and 3D near-eye displays to give the user an immersive feel of a virtual world.
Applications of virtual reality include entertainment (particularly video games), education (such as medical or military training) and business (such as virtual meetings).
What is meant by term Augmented reality?
Augmented reality (AR) is an interactive experience that combines the real world and computer-generated content. The content can span 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.
