Abstract
With the continuous development of information science and technology, human beings have been able to use computers to build diversified mass information space to fully express the objective world. Virtual reality technology on the basis of information modeling of the objective world, by means of human-computer interaction mechanism of multi-channel, real-time to provide realistic sensory information, help mankind to break and physical limitations of time and space, to perceive and research all kinds of complex events in the occurrence and development process of equivalent to the real environment, and human cognition of the world and to provide a new method and means. According to tend to the characteristics of different virtual reality, the virtual reality technology can be divided into the desktop virtual reality technology, the use of personal computers or desktop workstations are simulated, the virtual world of the computer screen as a participant observation window, this kind of technology in the aspect of immersive is poorer, but the cost is low, wide applicability, is the main entry point in the field of virtual reality technology into various applications. Immersive virtual reality technology: using the projection or head-mounted device build complete virtual reality environment, enables the user to fully immersed among them, the high cost of such technologies, application of pertinence, a typical system has the CAVE system based on the university of Illinois and the low stereoscopic display HMD. The augmented reality: the virtual environment of the graphic overlay on real objects, allowing the user to watch reality environment at the same time the object and the virtual environment. A more typical application is the penetration helmet-mounted display. The cost of such technologies is high, and the key technologies need to be further improved [1,2,2].
