摘要
通过力反馈装置,录取针灸专家的风池穴针刺手法,融入数字化虚拟人体,运用虚拟现实技术,构建虚拟风池穴针刺力反馈仿真系统,使操作者达到一对一的高仿真学习效果。在融合了风池穴信息的三维数字人体上,根据风池穴下各组织的物理特性,分析针刺过程中针体与组织的相互作用力,建立力学模型模拟针体受力,并通过力反馈设备真实地传递给操作者。初步实现了风池穴虚拟针刺力反馈仿真,使可视化的针灸虚拟人具有可现场模拟风池穴进针的触觉再现。风池穴针刺力反馈研究,为融合视觉、触觉和力反馈信息一体化的虚拟针刺作了初步探索,为针刺教学提供了一种动态的一对一仿真手段。
Acupuncture manipulations on Fengchi （GB 20） of famous doctors were taken through force feed- back device, then the data was input into a digitized virtual human. Virtual Fengchi （GB 20） acupuncture force feedback simulation system was built through the virtual reality technology to achieve one-to-one high simulative manipulation effect for acupuncture students. The interaction force of the needle body and human tissues was analyzed during the acupuncture process on the 3D digital human integrated with information of Fengchi（GB 20） according to the physical characteristics of the tissues under this point. The mechanical model which is used to imitate the stress received by the body of the needle was established, and transmitted truly to the operator by the force feedback device. Thus, Fengchi （GB 20） virtual acupuncture force feedback simulation was preliminary established, and the sense of touch could be reproduced lively on the visualized virtual acupuncture human. It is held that Fengchi （GB 20） acupuncture force feedback research is a preliminary exploration for virtual acupuncture that integrated with the information of visual, tactile and force feedback. And it also provided a dynamic one-to-one simulation approach for acupuncture teaching.
