Study on digital style design-digital design system of crack patterns on surfaces of pottery and chinaware based on KANSEI

Patterns are one of the important factors for aesthetic design of products. Crack patterns made on surfaces of pottery and chinaware as decorative era ft-patterns give users relief and peace. This paper proposes a digital design method of crack patterns which show required impressions. In the proposed method, crack patterns are generated by computer algorithm based on physical phenomenon according to required impressions of users or designers. The impressions for a crack pattern are represented by KANSE1 words with weights. The parameters to generate crack patterns are derived from a neural network system by giving the KANSE1 words with weights required to a crack pattern. A basic system to generate crack patterns is constructed according to the proposed method. The effectiveness of the proposed method is verified by experiments with questionnaires.
