Abstract: Social applications (apps) are becoming more and more important for the elderly in achieving various purposes and pursuing happiness. However, the design of social applications often ignores the user experience and needs of the elderly. It is necessary to design elderly-oriented social apps. Combined with user interviews, this paper obtained the design elements of elderly-oriented social apps, and designed the Kano questionnaire and importance questionnaire. 297 valid samples were obtained based on offline and online surveys. The Kano Two-Dimensional model is used to classify the design elements, and the priority of relevant elements is determined combined with the importance analysis. The study found that the elderly-oriented social apps should ensure the stable operation and rapid response of the system, shield inserted advertisements, set large fonts, simple interface and collection function. The findings of this paper will provide a theoretical reference for the design, evaluation, and user experience studies of elderly-oriented mobile applications.
