| 摘 要： | 人机交互是虚拟现实的关键技术之一,而虚拟手操作技术是人机交互技术的重要组成部分,是虚拟现实和运动学相结合的产物.在虚拟手操作技术中如何实现实时、准确的抓取一直是人们所关注的问题.首先研究了虚拟手在虚拟场景中的碰撞检测理论,并在此基础上制定了虚拟手对虚拟物体的稳定抓取规则,然后以Open Inventor为软件平台,采用数据手套和位置跟踪器作为主要的输入设备,实现了虚拟手对虚拟物体的抓取、移动、释放等一系列虚拟操作,实例证明了该技术具有很强的实用性.

| Abstract: | Human-computer interaction(HCI)is one of the key technologies of virtual reality(VR),and virtu- al-hand operation technology which combines virtual reality with kinematics is the main component of HCI.The key problem in virtual-hand operation techniques is how to achieve real-time and accurate grasping in virtual space.In this paper,the collision detection theories in virtual scene about virtual-hand,and the rules of virtual-hand stably grasping a virtual object based on those theories are discussed firstly.And then the technology is proved to be feasible through a series of virtual operations of virtual-hand such as grasping,moving and releasing,by using data gloves and motion tracker as input devices and based on Open Inventor. |
