Description
Technical Field

[0002] VR is the abbreviation of Virtual Reality, which means virtual reality in Chinese. Virtual reality technology is a computer simulation technology that can create and experience a virtual world. It uses computers to generate an interactive three-dimensional dynamic vision. Its entity behavior simulation system can immerse users in the environment. However, the problem in reality is that only VR helmets are needed, and a certain area of scene is required to meet the user's movement needs. The limitations of various circuit lines also make the actual movement unable to achieve intense effects.
