This paper points out that Kansei Design needs a good match between the customer and the producer. Recently; in the field of educational testing; Item Response Theory is drawing attention. In classical test theory; tests were given to examinees without considering any individual characteristics. The same tests were given to all examinees. But everybody knows that we have strong points and weak points. Some are good at sports. Others are good at arts. If a test is about sports; then those who are good or who like sports make a good score. And the score will be better; if the examiner likes sports. Now; it is found out that if an examiner and an examinee have more in common; then the examinee makes a better score. This is considered to be because an examinee understands the question better. And the examinees are more motivated and their scores keep going up question after question.
Many people emphasize the importance of considering personalities of customers in Kansei Design. But very few discuss how it is important to find a good match of Kansei between the customer and the designer. If their intersection is small; the product would not appeal to the customer. A designer should know who will be his or her customer and should make efforts to increase the size of intersection. It would not work if they do not share intersection at all or would not work effectively if the intersection is small.
