虚拟现实(Virtual Reality)目前还没有一个确切的真实再现。在通过各种技术模拟的环境中,用户可以像在现实环境中一样,接受和响应模拟环境的各种感官刺激,与其中的人及事物进行行为和思想等的交流,使用户有身临其境的感受。将真实的物质世界转化为虚拟世界,不仅要有计算机图形学、多媒体技术、计算机通信作为技术基础,而且要有模拟人脑思维模式和认知模式,并对用户的各种要求作出及时响应的技术条件。
Virtual Reality does not yet have an exact representation of reality. In an environment simulated by various technologies, the user can receive and respond to various sensory stimuli of the simulated environment as in a real environment, communicate with people and things therein, and conduct interactions such as behaviors and thoughts, so that the user can come and go. The feelings of the environment. Translating the real material world into a virtual world requires not only computer graphics, multimedia technology, and computer communications as the technological foundations, but also simulations of human brain thinking patterns and cognitive models, and timely response to various user requirements. Technical conditions.
