With the rapid development of digital technology, interactive digital narrative, as an emerging narrative method, provides a new perspective and path for the inheritance and innovation of traditional culture. Applying interactive digital storytelling to the field of cultural heritage is an important practice for the universal sharing of digital achievements in Chinese culture and the implementation of the “digital+cultural heritage” strategy. This article aims to explore the application framework and practical strategies of interactive digital narrative in the development of traditional culture. Taking traditional culture in Henan Province as an example, a development framework of “subject medium local traditional culture” will be constructed through interactive digital narrative innovation, innovating cultural content, enhancing cultural experience, and elaborating on the strategy of storytelling expression of local traditional culture. This provides theoretical reference and practical guidance for the digital dissemination and innovative development of traditional culture.
