摘　　要：提出了一种新的基于VR环境下的矢量场可视化的交互感知方法,将虚拟现实的交互技术和矢量场数据的可视化有机结合起来,给出了该方法的实现原理并探讨了其中的一些关键技术,用户可以通过三维跟踪设备、三维鼠标、数据手套等外设与矢量场数据进行自然交互,更快捷的发现并感知数据中感兴趣的或较隐蔽的细节部分,使许多抽象的、难于理解的原理和规律变得更容易理解。最后在Powerwall虚拟现实系统上进行实例验证,并应用在工程实践中。A new method in vector field data interactive visualization was brought forward, which combined VR and human-machine interactive technologies. The implementation principle and procedure were given and the key technology was also discussed in this method. And users could interact with vector field using VR device such as 3D Track system, neowand and data glove. Using this method, the scene was intuitively showed, the users could rapidly find the regions of interest in vector field data and some abstract principles became being easily understood. Last, the method in a Powerwall VR system was validated and it was put into practice.
