This document describes the concept of Virtual Reality


Before discussing the importance of networks in virtual reality services, this document will help you to understand the virtual reality and mixed reality clearly.

Concept of VR & MR

The picture above illustrates that Paul Milgram, professor at the University of Toronto in 1994, embodied the concept of virtual reality and mixed reality. In this picture, we can clearly see that virtual reality is clearly distinguishable from mixed reality.

Reality is literally pure reality. Reality is clearly bounded by time and space; hence, it is not possible for us to see beyond the current time and space nor the past because it is practically impossible to artificially change time and space.

On the contrary, Virtual Reality is completely separate from the present, completely free from time and space. It is the concept of virtual reality that allows you to experience the past and shape the future through virtual reality, and send a person in Seoul right now to Paris in 500 years ago.

In other words, virtual reality must be free of time and space, which is completely independent of reality from any device. This is the basic principle of virtual reality.

On the other hand, mixed reality is based on reality or based on virtual reality, overlapping time, space, and objects on the other side.
