摘　　要：在使用头戴式交互设备的虚拟现实(virtual reality,VR)环境中,人与虚拟物体的自然交互通常依赖手柄的使用,很难同时满足交互精度、速度及范围最优。文章提出一种新的交互方案,将平板设备与手柄绑定,用户在现实世界中利用手势操作平板,实现对VR场景中平板的同步操控,进而与VR场景中的物体交互。实验结果验证了该方案在保证高交互精度的前提下,交互的速度也能达到较高的水平,并且交互范围包含了整个VR环境中的所有物体。In the virtual reality(VR)environment using head-mounted interactive devices,the natural interaction between humans and virtual objects usually relies on the use of handles,and it is difficult to simultaneously satisfy the optimization of the interaction accuracy,speed and scope.This paper proposes a new interactive method.After binding the tablet device with the handle,the user uses the gesture to operate the tablet in the real world to realize synchronous manipulation of the tablet in the virtual scene and then interact with the object in the VR scene.The experimental results show that the method can achieve high level of interaction speed under the premise of ensuring high interaction accuracy,and the interaction scope includes all objects in the entire virtual environment.
