Development of interactive Kansei products design system

当前的计算机技术有很大的潜力来改进通常的生产系统。在本研究中，我们开发了一个由动态人体模型、三维服装模型数据库和虚拟试衣仿真组成的交互式三维服装设计系统。该系统使用户可以根据自己的喜好设计各种服装，并将通常服装生产中的打样和试衣过程也用计算机中的虚拟试衣模拟来代替。它可以减少试制过程中的浪费和时间，在服装工业和基于计算机网络的电子商务中具有广泛的应用价值。(1)建立了决定人体姿态的人体骨架模型和形成人体体形的人体表面模型。该模型可以通过测量信息来表达一个人的身材。(2)建立服装基本形状数据库，构建服装几何模型。(3)开发了包括服装造型模型、细节造型和布料纹理的交互式三维CAD系统。通过本系统，设计了。即使没有服装的技术知识，一般用户也可以在三维环境中穿衣服。此外，材料的感觉可以通过存储在数据库中的布料纹理的变化来表达。(4)开发了一个由设计的三维服装造型形成生产所需服装图案信息的系统。(5)开发了将人体模型与服装设计信息相结合的动态穿衣仿真系统。用户可以确认该系统设计的服装的穿着状态。(6)利用粒子模型，开发了考虑织物力学性能的逼真服装仿真系统。

Current computer technology has great potentiality to improve the usual production system. In this study, we developed an interactive 3-D apparel design system consisting of a dynamic human body model, a 3-D clothing model database, and virtual fitting simulation. This system enables users to design various kinds of clothes as they please, furthermore, the sample making and fitting process in the usual apparel production is also replaced by virtual fitting simulation in the computer. It can reduce waste and time in trial production and will be useful in apparel industry and electronic commerce based on computer network.( 1 ) We built human skeleton model that decides the posture and surface model that forms human body shape. This model can express a personal figure by using measuring information.( 2 ) A database of basic clothes shapes by which the geometric model of clothes can be construct are made,.( 3 ) An interactive 3 dimensional CAD system was developed, which includes clothes shape model, detail shapes and cloth textures. By this system, design of. clothes can be possible in 3 dimensions environment by the general user even they have no technical knowledge of clothes. Furthermore, the feel of material can be expressed by a change of cloth texture stored to the database.( 4 ) A system which formed dress pattern informalion necessary for the production from designed 3 dimensional clothes shape was developed.( 5 ) We developed dynamic dressing simulation system that combined the human body model with clothes design information. User can confirm wearing state of clothes designed by this system.( 6 ) Using particle model, realistic clothes simulation system considering mechanical properties of fabrics was also developed.
