In the context of global aging, to explore the design needs of elderly with dementia in museum environments, to establish a user cognitive psychological model based on immersion theory, and to enhance the satisfaction of cognitively impaired dementia with the museum service experience. Using literature research, surveys, questionnaires, interviews, and focus groups, we analyze the experience design from the psychological demands of elderly with dementia, build a method of mining user needs by combining the KANO model with the analytic hierarchy process (AHP) method, and establish a model for evaluating the excellence of the experience of the museum environment. The conclusion shows that displaying museum virtual scenes or old objects can effectively increase the subjective well-being of people suffering from various health conditions. The method can accurately tap the attributes of the needs of elderly with dementia, break through the drawbacks of the traditional museum experience design which is dominated by the designer's subjective consciousness, and allow the audience to better experience the museum immersive experience, which provides a new idea and method for the effectiveness of cognitive interventions for elderly with cognitive disorders.
