摘　　要：为了提高利用虚拟手交互模拟技术提供的视觉信息反馈真实感,在现有的碰撞及模拟交互方法的基础上,设计并实现简单、易用的虚拟手交互过程碰撞模拟方法.该方法采用的模拟形体结合刚体和可变形体,在碰撞和模拟过程中可以有效地保持渲染形体和模拟形体间的一致性.实验结果表明,采用该方法能够提供具有真实感的虚拟手交互模拟视觉信息反馈,有效地避免虚拟手和物体间的穿透,也能够保证一定的计算效率,可以满足相关应用研究的需要.A simple collision simulation method was proposed based on current methods in order to provide visually and physically realistic feedback of hand movement in hand related neural interface research. The method used a model combined of both solid and deformable objects to keep consistency between physical and visual data in simulation, Experimental results show that the method is valid in providing visually cor- rect results conforming physical rules without penetration. The simulation results are stable and effective for providing visual feedback in such hand related neural interface researches.
