Virtual Reality technology (English name: virtual reality, abbreviated as VR), also known as spiritual technology, is a brand-new practical technology developed in the 20th century.
Virtual reality technology includes computer, electronic information and simulation technology, and its basic realization mode is computer simulation of virtual environment, thus giving people a sense of environmental immersion. With the continuous development of social productive forces and science and technology, there is an increasing demand for VR technology in all walks of life.

Development history
1, the first stage (before 1963) is a stage containing the idea of virtual reality.
1929, Edward Link designed a simulator for training pilots. 1956, Morton Heilig developed the multi-channel analog experience system Sensorama.
2. The second stage (1963-1972) is the embryonic stage of virtual reality.
1965, ivan sutherland published a paper "ultimate display"; 1968, Ivan Su Zelan successfully developed a helmet-mounted stereoscopic display (HMD) with a tracker. 1972, Nolan Bscher invented the first interactive video game table tennis. ?
3. The third stage (1973-1989) is the emergence of the concept of virtual reality and the initial formation of the theory.
1977, Dan Sundin and others developed the data glove SayreGlove；; In 1984, Ames Research Center of NASA developed a virtual environment visual display for Mars exploration. 1984, JaronLanier of VPL Company first put forward the concept of "virtual reality"; 1987, JimHumphries designed the earliest binocular omni-directional monitor (BOOM) prototype.
4. The fourth stage (1990- present) is the further improvement and application stage of virtual reality theory.
1990 proposed that VR technology includes three-dimensional graphics generation technology, multi-sensor interaction technology and high-resolution display technology; VPL developed the first set of sensing gloves "DataGloves" and the first set of HMD "Eye Phones"; Since the 20th century, VR technology has developed rapidly, and software development systems have been continuously improved, such as MultiGen Vega, Open Scene Graph, Virtools and so on. ?
