VR是一项综合集成技术，涉及计算机图形学,人机交互技术,传感技术,人工智能等领域，它用计算机生成逼真的三维视、听、嗅觉等感觉，使人作为参与者通过适当装置，自然地对虚拟世界进行体验和交互作用。使用者进行位置移动时，电脑可以立即进行复杂的运算，将精确的3D世界影像传回产生临场感。(VR is a comprehensive integrated technology involving computer graphics, human-computer interaction technology, sensor technology, artificial intelligence and other fields, it generates a realistic three-dimensional computer vision, hearing, smell and feeling, make people as participants through the appropriate device, naturally on the virtual world to experience and interact. When the user moves in the position, the computer can perform complex operations immediately, sending the exact 3D world image back to the sense of telepresence.)
