Spatial Evaluation Method of Impression Considering Vagueness of Kansei and its Characteristics

摘要

This paper proposes a method of evaluating impressions using a space containing impression words. The impression of an object is specified by circling impression words that match its impression. The degree of matching of the impression is expressed by the darkness of the color used to paint the circled area. This method is called the Impression Evaluation Method by Space (IEMS). The IEMS considers the vagueness of Kansei. The IEMS poses few restrictions to users evaluating an impression, while the semantic differential (SD) method evaluates an impression in a predefined range for enabling statistical processing. A prototype system is implemented to evaluate the IEMS. This system enables a subject to evaluate their impression of a picture by using the IEMS. An impression evaluation experiment is carried out on several pictures to compare with conventional methods, such as the SD method. Various results of evaluation are obtained from this experiment, and consideration is conducted. Finally, it is shown that the proposed method can evaluate the aspects that other methods cannot. The IEMS enables users to express the degree that they feel in the continuous manner, the opposite feelings at the same time, and the feeling among several impression words. It also enables them to add the impression words that they want to use, and not to enforce the evaluation through all of the impression words.
