1.6.Development Of VR

From 1970s to 1980s, the whole theory and concept of virtual technology were formed.Various components of virtual helmet have been very mature in technology and can be bought in the market.

At that time, the graphic cards were able to render thousands of triangles per second and display complex three-dimensional image models. The portable LCD display produced by Sony could also present the picture completely. Polhemus has developed a head tracking device with six degrees of freedom. Compared with Sutherland mechanical link, the accuracy has been greatly improved and many constraints have been saved. At the same time, the glove with joint sensor realizes somatosensory operation. With the maturity of technology, virtual technology has been widely used in aerospace, simulated flight and other areas.The concept of virtual reality was finally put forward in the 1980s.

In the 1990s, the theory of virtual technology has been very mature, but the corresponding VR helmet is still a conceptual product. A VR helmet named "Virtuality1000CS" appeared in 1991, which fully shows the embarrassment of VR products - bulky appearance, single function and high price. However, the seed of VR Games was also planted during this period. The “VirtualBoy” host launched by Nintendo in 1995 was rated as one of the "50 worst inventions in history" by magazine. The hasty launch of the market turned the hardware from headset into tripod support. Coupled with the single red color displayed on the screen, the attached game works put off one after another. "VirtualBoy" survived just six months in the market, and the first attempt of VR game disappeared, but it also opened a door for VR hardware to enter the TOC market.

Nowadays,VR industry is booming because OculusRift raised $1.6 million through KickStarter, a well-known foreign crowdfunding website, in 2012, which was later take over by Facebook at a high price of $2 billion. At that time, Unity, as the first development engine supporting Oculus glasses, attracted a large number of developers to participate in the development of VR projects, such as Sony, Google, HTC, steam and other magnets.

With the rise of Metaverse, the recovery of capital and the improvement of end-users' acceptance of VR / AR, the market scale is expected to rise continuously. It is estimated that the global VR / AR industry market will reach US $12.19 billion in 2024, and the compound growth rate from 2021 to 2024 may exceed 36%.
