VR is a virtual reality technology industry. Virtual reality technology is a computer simulation system that can create and experience virtual worlds. It uses computer to generate a simulation environment, which is a multi-source information fusion, interactive 3D dynamic vision and entity. System simulation of behavior immerses users in the environment.
The history of the evolution of virtual reality technology can be roughly divided into four stages:
1. The simulation of voiced dynamics is the first stage of implication of virtual reality (before 1963);
Second, the burgeoning of virtual reality is the second stage (1963 - 1972);
Third, the emergence and theory of the concept of virtual reality was initially formed into the third stage (1973-1989);
Fourth, the further improvement and application of virtual reality theory is the fourth stage (1990-2004).
