This is a proposal to build a haptic interface to a mechanical design system. The objective is to demonstrate that part interaction, assembly, and manipulability can be evaluated without physical prototypes. Visual interactions are provided by a CRT screen, while haptic interaction is by means of force reflecting telerobotic master arms, which the user wears as an exoskeleton. Instead of controlling slave arms in a remote environment, the masters affect a virtual world in which the prototype assembly exists. Geometric and functional reasoning determine part contact, interference, and the propagation of forces and torques. Visual rendering techniques display the current state of the assembly. Haptic rendering techniques feed back appropriate forces to the master arms, enhancing the effectiveness of the interface.

这是为机械设计系统构建触觉界面的建议。 目的是证明可以在没有物理原型的情况下评估部分相互作用，组装和操纵性。 视觉相互作用由CRT屏幕提供，而触觉相互作用是通过反映远程动物主臂的力，用户将其作为外骨骼磨损。 大师们没有在远程环境中控制奴隶臂，而是影响了原型组件存在的虚拟世界。 几何和功能推理决定了零件接触，干扰以及力和扭矩的传播。 视觉渲染技术显示组件的当前状态。 触觉渲染技术将适当的力反馈到主臂上，从而增强了界面的有效性。
