Development Interface for creative design environment with haptic sensation

我们一直在开发一种新型的触觉设备，以操纵虚拟对象。该设备的名称被称为SPIDAR，它不仅提供用户指尖的指向能力，而且还在相应的指尖的顶部显示任意力的感觉。将该触觉设备与实时图形显示相结合，可以构建多模态的虚拟环境，在本研究项目中，我们开发了一个基于上述触觉虚拟环境的柔性设计支持系统。该设计系统由以下子系统组成：1.支持处理器子系统的自由曲面造型设计;三维自由造型模型管理子系统;自由曲面设计的形状处理子系统;自由曲面输入子系统，明确了对这些子系统的基本要求。在此基础上，设计了虚拟环境的基本结构和界面环境。形状设计的实验结果表明，所开发的系统是有效的。

We have been developing a new type of haptic device in order to manipulate virtual objects. The name of the device is called SPIDAR, which provide not only pointing capabilities of user, fingertips but also displaying arbitrary force sensation at the top of the correspondent fingertip. Combining this haptic device with a real-time graphic display, we can construct multi-modal virtual environments.In the research project, we have developed a flexible design supporting system based on the above haptic virtual environment. The proposed design system is composed with the following subsystems :1. Free-form shape design supporting processor subsystem,2. Management subsystem of 3D free-from shape modelers,3. Shape processing subsystem for free-form design,4. Input subsystem for free-form shape.Basic requirements for these subsystems have been made clear. Based on these requirements, we have designed the basic structure of the virtual environment and the interface environment. The effectiveness of the developed system is clarified by experiments of shape design.
