一个多感知虚拟现实系统的建立

建立了一个基于视觉、听觉和力觉融合的多感知虚拟现实系统。采用一种新型解耦双并联结构的6自由度主操作手实现人机交互并提供力觉感受;设计了基于OpenGL与OpenAL的软件引擎,在PC机上实现了高性能的立体视觉与听觉。通过一个虚拟乒乓球掂球实验验证了本系统的高性能与控制方法的有效性．

Implementation of a Multisensory Virtual Reality System

This paper proposes a multisensory virtual reality(VR) system which can provide users with senses of vision,audition and force.Under the guidance of multisensory fusion strategy,a PCbased high performance system is implemented.We use a novel 6DOF haptic device to realize friendly and efficient interactivity in virtual environment.To generate sense of immersion,a V6 head mounted display(HMD) with position/orientation tracking system is adopted. In addition,OpenGL and OpenAL based software engines are developed to produce stereo signals of vision and audition for the HMD.Finally,a virtual table tennis experiment is designed to verify the systemic high performance and validity of the strategy.
