ABSTRACT
In this chapter, methods of Kansei/affective engineering that have been developed to date will be described together with an illustrative case of Kansei product development.
Category classi‡cation is a tree structure from a main event to subsequent subevents, as shown in Table 2.1. This method was utilized by Mazda. The CEO decided on a new car development in which the target was young drivers and the product domain was a sports car. The project team sat next to the driver with a camcorder and recorded the driver’s operation. Another team stood in an intersection and recorded the young driver’s maneuvering. After that, the team members examined all of the picture frames and used the card method to record their œndings. When they got a hint or suggestion from pictures, they noted a keyword on each small card (called a K-card); one word on one card. If the team found several K-cards with a similar concepts or meanings, these cards were gathered into one group. The total number of K-cards from examining the pictures was about 600, which were organized into about 20 groups, which is an average of 30 cards in each group. These

groups were arranged from top concepts to more fundamental groups in a tree structure, as shown in Table 2.1 (Nagamachi 1995).
