As a national intangible cultural heritage of China, comb is a traditional handicraft with a long history, and the rapid development of virtual museums provides a new direction for the deep communication between traditional handicrafts and modern life. Under the guidance of interactive narrative theory, constructing a linear tour path of the digital museum based on the comb-grate craft process can help deepen visitors’ experience, help them better understand the comb-grate craft and stimulate their interest in comb-grate culture. This study innovatively combines and explores the interactive narrative theory, traditional handicraft heritage and digital museum at a deeper level. Thus, it innovatively promotes the realisation of immersive experience in the digital museum of traditional handicrafts. It provides a case reference for the combination of the same type of handicrafts and digital museums as well as interactive design.
