Interactive design support system by customer evaluation and genetic evolution: Application to eye glass frame

Abstract

To respond to the quickly changing and diversifying customer's requirements, a system for supporting an industrial design where a customer can personally participate in the design process is proposed. Our system uses Interactive Evolutionary Computing (IEC) technique where a customer can express his or her requirement such as a Kansei image by interacting with the system. To demonstrate the effectiveness of our system, we applied it to the design of an eyeglass frame shape. Harmony with the customer's face is an important key factor in the design of an eyeglass frame. In our system, the user evaluates some samples suggested by our system, and then gradually he or she comes to the design he or she likes. The systems' effectiveness was demonstrated through the experiments of user operations and questionnaires.
