Background In light of the rapid aging phenomenon, the importance of healthcare management for the senior population has been steadily gaining prominence. Specifically, as digital healthcare services emerge as a critical means to address these demands, there is an increasing emphasis on the need for research that focuses on the user experience (UX) of the senior demographic in designing these services. Designing services tailored to the needs of the senior population has become imperative as a response to the challenges posed by the escalating aging population. Methods This study investigated the concept of seniors and trends in the senior digital healthcare market. Additionally, it delved into the definition and methodology of User Experience research. For the ethnography research methodology, the incorporation of non-verbal observation through a Photo-Diary and verbal observation through In-Depth Interviews was employed. Finally, a Focus Group Discussion (FGD) was conducted to extract integrated insights. Result Based on a total of 11 ethnographic research findings, a total of 60 common key factors and 15 insights were derived. The identified factors and insights were validated through a focus group discussion (FGD) involving 4 experts. The final insights were extracted in two areas, targeting seniors and senior-care workers. Finally, two insights were deducted from each set of three insights. Conclusion Through this study, we anticipate contributing as a preliminary research endeavor to inform the formulation of policies and the development of service designs in the field of senior digital healthcare.
