Virtual reality technology is an important direction of simulation technology?

Virtual reality technology is an important direction of simulation technology, is a collection of simulation technology and computer graphics human-computer interface technology multimedia technology sensing technology network technology and other technologies, is a challenging cross-cutting technology frontier disciplines and research areas. Virtual Reality (VR) technology mainly includes simulation environment, perception, natural skills and sensing devices. The simulated environment is a computer-generated, real-time dynamic three-dimensional stereo realistic image. Perception means that the ideal VR should have all the perceptions that a human being has. In addition to the visual perception generated by computer graphics technology, there are also perceptions such as hearing, touch, force, motion, and even smell and taste, also known as multisensory. Natural skills refer to human head rotation, eye, gesture, or other human behavioral actions, which are processed by a computer that processes data appropriate to the participant's actions and responds to the user's inputs in real time and feeds back to each of the user's five senses. A sensing device is a three-dimensional interaction device.
