Virtual reality technology is a computer simulation technology that can create and experience virtual worlds. It uses a computer to generate an interactive three-dimensional dynamic scene, and its physical behavior simulation system can immerse users in this environment. Virtual reality technology mainly includes simulated environment, perception, natural skills and sensing equipment. The simulation environment is a computer-generated real-time dynamic three-dimensional realistic image.
Perception means that the ideal VR should have the perception that everyone has. In addition to the visual perception produced by computer graphics technology, there are hearing, touch, force and movement, and even smell and taste, also known as multi-perception. Natural skills refer to people's head rotation, eyes, gestures or other human actions. The computer processes the data adapted to the actions of the participants, responds to the user's input in real time, and feeds it back to the user's five senses respectively.
Development history
The evolution history of virtual reality technology can be roughly divided into four stages: the first stage (before 1963) contains the idea of virtual reality; The second stage is the bud of virtual reality (1963-1972); The emergence of the concept of virtual reality and the initial formation of the theory are the third stage (1973- 1972).
