Kansei engineering aims to translate feelings and impressions into product parameters. Employing
Kansei information will become increasingly important in the fields of food and the environment. This is because
Kansei information will enable us to design, develop, and evaluate agricultural produce and food which are prominent targets for consumer evaluation, letting us conceive comfortable interior spaces, and create urban and rural landscapes high in amenity effect. Until now, we have investigated facial expression information and its relation to
Kansei, and conducted facial expression analysis by employing the Facial Action Coding System (FACS) and facial node imaging. In this report, we developed a two-dimensional dynamic facial expression tracking system which we utilized in specifying important facial nodes. We established a
Kansei inference method using facial expression information and employed degree of similarity and the nearest neighbor rule (NN rule) to conduct differentiation. The potential for facial expression -
Kansei inference was suggested through differentiation by using the ratio in the change in area of a normalized polygon as facial feature vectors. We shall report on our findings here.
