The work aims to study the immersive experience design method and design practice of public facilities in scenic spots from the perspective of interactive narrative. Based on analysis and research on the interactive narrative features and constituent elements, the relationship between interactive narration and creating immersive experiences were explored, and the core contacts in the process of immersive experience were summarized. The immersive experience design methods of public facilities in scenic spots were deduced as follows:nonlinear tour line, cross-media sensory and spatial immersion, story experience value. Through the construction of interactive narrative contexts, the experience design process framework of investigation and analysis, function transformation, project design and prototype display was obtained. The feasibility and effectiveness of the method were verified by the experience and application design of the Jinji Lake Taohua Island Project. In conclusion, designers encode narrative spaces and narrative contents, create narrative situations and set tour lines through non-linear narrative. Local culture and history were extracted as story themes. Cross-media narrative means are used to build digital public facilities. The new media technology is used to mobilize the five senses of experiencers, optimize the immersive interactive experience, build a multi-dimensional immersion experience, to blend the whole body senses of experiencers with the surrounding environment to achieve an immersive effect.
