虚拟现实(Virtual Reality,VR),又称“灵境”技术,是90年代兴起的一个新技术领域,它汇集了计算机图形图像、立体视觉、人工智能等各方面新技术以及生理学、心理学、认知科学等理论。从本质上说,VR 技术是一种先进的计算机用户接口技术。它利用计算机生成一种模拟环境(如飞机驾驶舱、舰船内外场景、战场等),通过各种传感设备使用户“投入”到该环境中,实现用户与该环境直接、自然地交互。VR 技术的三大特征是:Immersion(投入)、Interaction(交互性)、Imagination(想象力),简称“3I”。
Virtual Reality (VR), also known as “Lingjing” technology, is a new technology field that emerged in the 1990s. It brings together new technologies such as computer graphics, stereoscopic vision and artificial intelligence as well as physiology, psychology, Science and other theories. In essence, VR technology is an advanced computer user interface technology. It uses computers to generate a simulated environment (such as aircraft cockpit, ships inside and outside the scene, the battlefield, etc.), through a variety of sensing devices to enable users to “invest” into the environment, enabling users to interact directly and naturally with the environment. The three main features of VR technology are: Immersion, Interaction, Imagination, or “3I.”
