摘要
针对现有手部运动模拟控制的复杂性,通过分析人手解剖学结构及运动特性,提出了基于多线谱控制的虚拟人手运动及控制机制。针对单指运动,通过控制该指上的多条肌肉归一化收缩量,驱使单指关节的灵活运动;在多指协同运动中,由于相邻手指之间存在运动促进和制约的关系,因此要考虑其他手指的影响,根据其约束关系,控制相应的肌肉收缩,实现多指协同运动。实验表明,所建立的控制机制能较好地仿真单指及多指间的各种运动,在多线谱的控制下,能够方便快捷地仿真多种手势及手语,且运动效果逼真,手部运动自然灵活。
In view of the complexity of existing motion simulation control of the hand, through the analysis of structure and movement characteristics of human anatomy, the movement and control mechanism of virtual hand was proposed which is based on multi-curve spectrum. For the movement of single finger, flexible movement of single knuckle can be driven by controlling the normalization contraction of muscle. However, in the cooperative movement of fingers, because the movement promotion and restriction relationship between adjacent finger exists, the effect of other fingers should be considered. According to the constraint relate, the coordinated movement can be realized by controlling the correspon- ding muscle contraction. Experiments show that the established control mechanism can well simulae not only the move- ment of single finger but also coordinated movement of fingers. Under the control of multi-curve spectrum, it is conven- ient and quick to simulate a variety of gestures and sign language. Besides, the movements are vivid, and the hand move- ments are natural and flexible.
