The work aims to explore the way of independent medical service for visually impaired patients from the perspective of patients, propose a design method of independent medical service for visually impaired patients based on user experience to optimize the user experience in the medical service for visually impaired patients. First of all, based on the current indicators on medical experience of patients, the experience indicator system was optimized and the observation indicators were updated in combination with features of visually impaired patients. Based on the different observation methods, the indicators were reorganized, and the reorganized indicators were constructed into an observation framework and an interview outline to collect user data. Then, the data were measured for user experience, and the experience level of each stage of outpatient care was sorted. The stages were classified and the user behavior in different stages was analyzed according to the calculation results, so as to extract service pain points and convert them into design factors. Finally, integrating the design factors at each stage, fuzzy kano was used to verify its effectiveness, and priority ranking was carried out. The design of the optimization system for independent medical service of output visual impaired patients included a guide car and an online medical care module. From the efficiency of the process and user satisfaction before and after optimization, the service after optimization is higher than that before optimization. The method is verified to be scientific and reasonable, providing reference for other similar projects.
