Construction of Interactive Conceptual Design System Using Common Feature Expressing Rules

Abstract

This study aims to construct a new framework for conceptual design support system in the field of Industrial Design. In the system, the Interactive Genetic Algorithm is introduced to generate the tableware which reflect users' conceptual feeling. Users evaluate pairs of tableware, which are generated as chromosomes by the system. Then the system re-generates next generation candidates based on the evaluation results. Repeating the interaction, users acquire pair of tableware which reflects users' feeling. In the chromosome of GA, "Feature Expressing Rules," which generate shapes of parts from linguistic feature, are used. In this paper, in order to reflect the users' feeling more effectively, the system saves and uses the rules which are common among the users' good evaluated shape.
