With the arrival of the era of digital intelligence, the way information is disseminated has changed, and the form in which users receive information has also undergone significant changes. As a public welfare institution focused on cultural education and dissemination, museums not only collect, store, and research natural and human cultural things, but also provide services such as knowledge popularization and education for the public. The main function has shifted from displaying "objects" as the main focus to serving "people" as the center, providing various experiences for education, appreciation, contemplation, and knowledge sharing. People's visits to museums have entered a stage of cultural enjoyment that focuses on experience, from shallow cultural relics viewing. This has put forward higher requirements for the level of experiential service in museums. On the one hand, expanding people's participation and achieving the popularization of cultural relics education; on the other hand, the surge in the number of visitors has put enormous pressure on museum operations and service facility configuration. In this context, how museums optimize their service system is a topic worthy of social attention and research to solve. This paper takes museums as the research object, based on service design theory, analyzes the internal connection and value between stakeholders, user profiles, user experience maps, touchpoints, and other aspects of the museum system, explores the service design methods and strategies of the museum app, and achieves the goal of improving the quality of museum services and optimizing user emotional experiences.
