What is the principle of virtual reality

Virtual reality" is from the English "Virtual Reality", referred to as VR technology. It was first proposed by Joe Lanier of the United States in the early 1980s. Virtual reality technology (Ⅵ) is a set of computer technology, sensor technology, human psychology and physiology in one of the integrated technology, which is through the use of computer simulation system to simulate the external environment, the main model

objects are the environment, skills, sensing equipment and perception, to provide users with multi-information, three-dimensional dynamic, interactive simulation experience

VR technology can be applied to the field of More, at present the use of du more fields including medical, engineering, military, aviation, navigation and other aspects, such as the aviation field, aerospace pilots in the training cabin in the face of the screen to carry out a variety of driving operations, the simulation of the cabin outside the scene of the screen image changes, the pilot can get the simulation of the training experience. This way of putting people in the image environment has been used in aircraft simulation training for decades. There are also in the field of entertainment, games, education, augmented reality VR technology application prospects are even more extensive. In physics classes, students can create their own natural landscapes such as rainfall and water vapor, which are intuitively interesting and vivid. This novel teaching method is also realized through VR technology. It can be said that VR can create a future, present, past, real or fantasy world. At present, many games have been the first to use this technology, popular with young people.
