Abstract
Understanding the users can contribute to creative design. Particularly, user behavior observation can explore potential needs. In this study, we proposed a method using episode description tool and video data
protocol. In a design idea experiment, we compared a group of participants using tool and a video only group. From the result of the analysis, in both groups, the design idea was considered from the presented video. Nevertheless, the group using the tool could watch video more efficiently. The episode description supported the exploration of user needs. Further discussion regarding episode description may explore needs more effi ciently.
