项目摘要

The final goal of this research is to manage the design manufacturing production process including the design of an artificial object, parts manufacturing, assembly and an exterior design by using virtual objects instead of real objects. Then all engineers and designers concerned with the above design stages can participate in the design change process at any time.In this process, engineers can add any revision to an artificial object through the description in an exclusive computer language. But, a designer changes the design using drawings or models from an aesthetic point of view, and has different emotion and description capability from the other participants. Consequently, it is difficult to reflect his idea on the design of the objects. So a system helping the designer design / modify virtual objects is necessary. We produced the experimental exterior design system enable him to use his hand and a language in handling virtual artificial objects in order to achieve this purpose.In … More a design change, cutting operation also becomes necessary in addition to parts addition. We experimentally created a system to help him do free cutting operation in real time because there is no virtual reality system which supports cutting operation.Interaction with the system must be performed with a spoken language in order to specify the virtual object with a data glove while wearing an HMD and looking at the object. So the mechanism is installed into the virtual reality system which a verbal information and a nonverbal information can be input into in parallel. On the other hand, as the design participants are working in different places, they have no opportunity to surround the design object and to change their opinions. On this account it is difficult to obtain quickly the design proposition with which all the members are satisfied. Using server client system, we construct the framework that has them share a virtual environment in order to help them. But there is no enough time to build all systems mentioned above into the exterior design system. We cannot create the translator converting the description of virtual objects into STEP description.

本研究的最终目标是通过使用虚拟对象代替真实的对象来管理设计制造生产过程，包括人造对象的设计、零件制造、装配和外观设计。所有与上述设计阶段相关的工程师和设计师都可以随时参与设计变更过程，在这个过程中，工程师可以通过专用计算机语言的描述，对一个人工对象进行任何修改。但是，设计师从美学的角度使用图纸或模型来改变设计，并且具有与其他参与者不同的情感和描述能力。因此，很难将他的想法反映在物体的设计上。因此，一个帮助设计者设计/修改虚拟对象的系统是必要的。我们制作的实验性外观设计系统使他能够用他的手和一种语言来处理虚拟的人造物体，以达到这个目的。 ...更多信息设计改变，除了部件添加之外，切割操作也变得必要。由于没有支持切割操作的虚拟现实系统，我们实验性地创建了一个系统，帮助他在真实的时间内进行自由切割操作。为了在佩戴HMD并观看对象的同时使用数据手套指定虚拟对象，必须使用口头语言与系统进行交互。因此，该机制被安装到虚拟现实系统中，其中语言信息和非语言信息可以并行输入。另一方面，由于设计参与者在不同的地方工作，他们没有机会围绕设计对象并改变他们的观点。由于这个原因，很难迅速得到所有成员都满意的设计方案。利用服务器客户端系统，我们构建了一个框架，使他们共享一个虚拟环境，以帮助他们。但是，没有足够的时间将上述所有系统构建到外部设计系统中。我们无法创建将虚拟对象的描述转换为STEP描述的翻译器。少
