Abstract
Product design requires careful consideration of many factors. However, it is difficult for many developers to design a product that satisfies everybody because they have no idea "What causes large number of people to like a specific product?" "What fascinates them about the product?" or "Which part or element of the design makes it attractive?" This paper proposes a method for investigating "attraction" by a fuzzy decision tree. It builds a decision tree based on the results of a questionnaire, which determines user's product impressions, and helps in discovering major factors that affect their "attraction." In this paper, we analyzed running shoes and investigated the factors that determine their specific attraction.
