製品設計の初期段階において定性データの取得が困難な利用者を対象とする製品開発

抄録

In the product design, it is important deeply understanding the profiles of target user. For deriving the user profiles, it is required to collect, organize, and analyze data on the target users. However, there are some users from whom it is difficult to directly obtain qualitative data in the initial stage of product design, due to factors such as age. Therefore, for such target users, we have devised a spiral model development method combining human-centred design by Personas and the verification of product candidate by users, starting with Assumption Personas. In this study, we applied this methodology to the development of a "Digital Learning Aid for Writing" for infants and younger children from whom it is difficult to obtain qualitative data directly in the initial stage of product design, and studied the effectiveness of this methodology.
