Virtual Reality "comes from English" virtual reality ",referred to as VR technology. It was first put forward by Joe Lanier of the United States in the early 1980s. Virtual reality technology (ⅵ) is a comprehensive technology integrating computer technology, sensor technology, human psychology and physiology. It simulates the external environment by using a computer simulation system. The main models are environment, skills, sensing equipment and perception. To provide users with multi-information, three-dimensional dynamic and interactive simulation experience. VR technology can be applied in many fields. At present, du is widely used in medical treatment, engineering, military affairs, aviation and navigation. For example, in the aviation field, space pilots perform various driving operations on the screen in the training cabin, and the screen image of the simulated extravehicular scene changes accordingly, so that the pilots can get a simulated training experience. This way of putting people in the image environment has been applied in aircraft simulation training for decades. In addition, in entertainment, games, education and other fields, augmented reality VR technology has a wider application prospect. In physics class, students can make their own natural landscapes such as rainfall and water vapor, which are intuitive, interesting and vivid. This novel teaching method is also realized by VR technology. It can be said that VR can create a future, present, past, real or dreamy world. At present, many games have taken the lead in adopting this technology, which is widely welcomed by young people. VR is an emerging technology, and Chinese translation is virtual reality technology. Simply put, VR is to restore something through computer technology. Although something is fake, it will make people really believe it is true. It's like generating an apple with VR technology. This apple is fake, so it can't be seen by the naked eye. It's not true. But if you bring a VR device, you can see the apple, touch it and even smell it.
