VR环境下的虚拟手自然交互方法研究

Research on Natural Interaction Method of Virtual Hand in VR Environment

针对当前基于VR的虚拟仿真系统存在的沉浸式交互体验感较差、物理效果较难模拟等问题,提出一种VR环境下基于物理属性的虚拟手自然交互方法。将虚拟物体物理属性与启发式交互方法相结合,避免了交互过程中虚拟手与虚拟物体相互穿透,实现了虚拟物体位姿随虚拟手接触点变化实时调整与自适应。最后,借助HTC VIVE虚拟现实套件以及Leap Motion体感控制器所搭建的沉浸式人机交互环境,对各类虚拟物体的交互操作进行实例验证并测试计算效率,验证了该方法的可行性。

Aiming at the problems of poor immersive interactive experience and difficult simulation of physical effects in current VR-based virtual simulation system,a natural interaction method of virtual hand based on physical attributes in VR environ⁃ment is proposed.By combining the physical attributes of virtual objects with heuristic interaction method,the interpenetration be⁃tween virtual hands and virtual objects is avoided,and the real-time adjustment and adaptation of virtual objects′pose with the change of virtual hands′contact points are realized.Finally,with the help of the HTC VIVE virtual reality suite and the immer⁃sive human-computer interaction environment built by Leap Motion somatosensory controller,the interactive operation of various virtual objects is verified and the calculation efficiency is tested,which verifies the feasibility of the method.
