Top2. An Overview Of Virtual Reality Technology
Virtual reality technology is a kind of advanced human-computer interaction technology that combines various technologies to create a realistic artificial simulation environment, and can effectively simulate the human visual, listening, tactile and other perceptive behaviors of human beings in the natural environment(Gatica-Rojas & Méndez-Rebolledo, 2014). It integrates many techniques such as computer graphics, multimedia technology, artificial intelligence, man-machine interface technology, sensor technology, highly parallel real-time computing technology and human behavior research. It is the high-level integration and intersecting of these technologies.
It gives the users a more realistic experience and provides a great convenience for people to explore the movement and change rules of things in the macro and micro worlds. It will fundamentally change the way people interact with the computer system. At present, virtual reality technology has been widely used in many fields, such as military, engineering, medicine, education and so on. And with the continuous development of virtual reality technology, it will show a wider application prospect(Bao et al., 2013).
2.1 The Fidelity of Virtual Reality Technology
Virtual reality technology is a virtual world of three-dimensional space based on the various senses and heart characteristics of human beings, which is produced by the computer and has a realistic stereoscopic nature. Virtual reality technology is the imitation of the real world, and the experiencer can feel the sensory experience of being on the scene.
