面向对象的虚拟手技术研究及实现

虚拟手技术是一种很有前途的人机交互技术。本文采用面向对象的方法，建立了一个虚拟手模型，并给出了从人手到虚拟手合理的运动映射算法。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，开发了一个虚拟手原型系统，实现了人手与虚拟手的直接交互，并能自然、高效地完成一些虚拟操作。

Research and Implementation of the Object-Oriented Virtual-Hand Technology

The virtual-hand technology is a promising human-computer interaction technology.In this paper,a virtual-hand model is established by the object-oriented method,and the algorithm of motion-mapping between a human hand and a virtual hand is proposed.Then a virtual-hand prototype system is developed by using Open Inventor as the software platform and using a data glove and a motion tracker as the input devices.Interaction between a human hand and a virtual hand can be implemented directly,and some virtual manipulations can be accomplished naturally and efficiently in this prototype system.
