摘　　要：针对在沉浸式虚拟现实环境中进行自然高效的交互问题,提出了一种新的头戴式虚拟现实(HMD-VR)空间中的人机交互方法.使用平面辅助物将智能平板的交互范式引入到头戴式虚拟现实环境中,通过单深度相机对平面辅助物与手部的有效跟踪构建了一个高效的交互系统;针对虚拟空间与真实空间交互平面的尺寸差异所带来的交互错误,提出了一种触觉重定向方法,使得交互操作可以在相邻目标间连续切换,并能有效防止切换时的虚拟手抖动;实验结果表明该交互方法不仅易于使用,而且提高了交互效率和交互准确性.Aiming at the problem of natural and efficient interaction in immersive virtual reality environment,a new Human-Computer Interaction Method for Head-mounted Virtual Reality Space was presented.A Planar-aid was used to introduce the paradigm of the smart tablet to the head-mounted virtual reality environment.An efficient interaction system was implemented by tracking the hand and Planar-aid efficiently with single depth camera.For the interaction error caused by the size difference between the virtual and the real interaction plane,an improved haptic retargeting solution was proposed.The solution was arranged to enable the interaction operation to switch between adjacent targets continuously,and also to effectively prevent virtual hand from shaking during switching.Test results show that the method can not only be easy to use,but also can improve the interaction accuracy and interaction efficiency.
