摘要
虚拟现实通过模拟人的视觉、听觉、力触觉等,使人处于一种与真实世界非常逼真的虚拟世界中,来感受、体验和评价虚拟世界中的场景和设备。力触觉在虚拟现实环境中有其突出优越性,力触觉使得虚拟现实环境变得真实,是唯一的既可接受周围环境输入又可以对周围环境输出的感知通道,可极大增强可视化表达的效果。虚拟现实的力触觉交互技术包括力触觉再现技术和虚拟环境的力触觉建模。介绍了这两方面的发展现状、存在的问题和今后的发展趋势。
People can be immersed in a vivid virtual world by simulating their vision, hearing and haptic in virtual reality system, and they can sense, experience and estimate the scene and the device of the virtual world. The haptic sense is a very important in virtual reality, because it can make the virtual reality to be realistic, and it is the only channel by which the information can imported and exported, further more, the effect of the vision can be enhanced. The haptic interaction technique of the virtual reality comprises of the haptic feedback and haptic modeling in virtual environment. The current development situation, the problems and the future trend of the haptic feedback technique and the haptic modeling technique are summarized individually.
