Abstract

In this paper, the authors propose a shape generation method based on the personal Kansei. The method works through an interaction between the user and a computer system. Several methods have been proposed to externalize “Tacit Kansei”, which is difficult to externalize the objective information such as words, although the user notices in his/her mind, up to now. On the other hand, “Latent Kansei”, which the user does even not notice in his mind, has not been discussed. The authors focus on Latent Kansei. The purpose of the method is to help the user to evoke the Latent Kansei by noting user's points of attention. A computer system generates new design samples based on the points of attention selected by the user. Reduct calculation in rough set theory is applied to estimate the features. The user externalizes both of Latent and Tacit Kansei through the iteration of the interaction process: generating design samples, showing the user's point of attention and evaluating design samples by the user. The system was compared to a conventional design system in which the user adjusts the design parameters by him/herself, and effectiveness of the system is demonstrated by experiments of shape design.
