The work aims to analyze the user needs of outdoor back massager and classify and prioritize the needs to find the needs that can be used to improve user satisfaction, thus providing new design reference for the innovative design of outdoor back massager. The initial needs of users for outdoor back massager were obtained by literature analysis and interview. KJ method was used to summarize user needs. Through the selection of questionnaire and Kano model, four need attribute categories and ordering of outdoor back massager for the middle-aged and the elderly were obtained.
