There are many phenomena in an aging society that are worth paying attention to, among which the phenomenon of elderly people living alone for a long time inevitably leads to feelings of loneliness and alienation. This study focuses on the application of emotional design to products for elderly people using the concept of flow theory. Through emotional design and flow theory, this study aims to provide spiritual comfort to the elderly living alone who often experience loneliness and isolation. Three experts will be interviewed and their responses will be analyzed to identify the key elements of emotional design for elderly products. In addition, four elderly people will participate in a game to observe and record their experience, and a questionnaire will be used to evaluate whether the game helps them to enter the state of flow, thus reducing their sense of loneliness. The collected data will be analyzed to propose improvement strategies and establish a set of emotional design elements for product design, which will draw more attention to the mental health issues of the elderly living alone.
