基于触觉反馈和运动约束的虚拟装配操作

该文将人对虚拟对象的抓取分为两个过程,然后分别对这两个过程的触觉反馈进行模拟,使用户产生真实的操作感觉。然后根据零件在装配过程中受到的约束,对零件的运动进行约束,同时提出基于虚拟工具的运动轴线与连接件的轴线对齐的方法对虚拟工具的运动进行约束,从而实现自然直观的交互手段。

Virtual Assembly Manipulation Based on Haptic Feedback and Motion Constrain

The paper presents an approach wh ich divides the grasp manipulation into two process and simulate s the haptic f eedback in the two process respectively,consequently makes the user feel reali sm.Then the motion of part is constrained according to the restriction that the part got during assembly.At the same time the motion of the virtual tool is constrained based on the approach that the locomotor axis of the virtual tool i s aligned together with the axis of the join.The above mentioned approaches can provide robust and intuitionistic interactive manipulation.
