The Impression Evaluation Method by Space (IEMS) and its analysis method focusing on the peaks of darkness called IAMS_PD have been proposed. The IEMS uses a plane containing impression words as the Kansei space. The impression of an object is specified by circling the areas matching the impressions. The degree of matching the impression is expressed by painting color. We can analyze characteristic impressions by using the IAMS-PD because peaks are mapped to the baseline Kansei space, and can be compared with each other. This paper proposes a method of mapping peaks in an individual Kansei space to the baseline Kansei space. The proposed method uses the spatial relationships of impression words in Kansei space to map peaks. This paper shows the soundness of proposed method by presenting the results of the mapping of peaks.
