In Kansei engineering, numerous studies have quantitatively represented the shape feature. They mainly focused on an object under a particular cognitive condition for the quantitative representation. However, human impression is influenced by diverse cognitive conditions. To quantify shape features, the relationship between an object and cognitive conditions is considered. First, the issue of conventional Kansei engineering from the viewpoint of the Multispace Design Model is summarized, and it is suggested that studies of state elements have been little investigated in conventional Kansei engineering. Second, a general model of Kansei with regard to the influence of cognitive conditions is proposed. Finally, experiments for complexity and beauty in the presence of a shadow or its position as a cognitive condition are conducted. Beauty is a variant of the presence of a shadow or its position. In the shape features without influence of the cognitive condition, complexity is represented by the curvature entropy as attribute elements, and beauty is represented by the degree of the golden ratio as attribute elements. In the shape feature with inflence of the cognitive condition, beuaty is represented by the distance between the center of gravity and the shadow as state elements.
