在对手结构和手关节运动深入分析的基础上,建立了基于约束的、以关节为节点的“父、子物体”链接的虚拟手模型,绘制了虚拟手.通过对数据手套及接口的分析与设计,根据手运动类型的约束条件及图形变换原理,实现了基于数据手套的手势合成、碰撞检测和碰撞处理的三维交互操作环境.在该虚拟环境中,虚拟手可以进行飞行、抓取、释放物体等各类运动与操作.

In this paper, a restriction-based virtual hand model that uses a“father and son”link with the joints as nodes has been established based on the analysis of hand structure and joint motions. And then a virtual hand has also been drawn. By analyzing and designing the digital glove and interface, a digital glove-based 3D interactive operation environment used for gesture synthesis, collision detection and collision treatment is realized according to the motion type restriction condition and graphic transformation. In this environment, the virtual hand can conduct different motions and operations such as moving, grasping and releasing etc.
