Restoring Dunhuang Murals: Crafting Cultural Heritage Preservation Knowledge into Immersive Virtual Reality Experience Design

With the development of digital technology, tourists have higher expectations for their experiences with digital cultural heritage (CH). However, there is limited research and design guidelines on how to effectively convey expert knowledge and transfer the value and connotations of digital CH to users in a virtual environment. Based on existing literature, we proposed a systematic design strategy for immersive virtual reality (IVR) systems, incorporating multimodal interaction, gamification, and storytelling for CH presentation, development, and promotion to the public. Accordingly, taking the virtual restoration of the Dunhuang murals as an example, we developed an IVR system that provided users with learning, interactive, and entertaining experiences, facilitating their transition from mere visitors to active learners while engaging with digital CH. We conducted a between-subjects user study involving 42 participants. The results demonstrated that our IVR system motivated users interests in CH, promoted CH preservation awareness, and could be applied in the domain of digital CH experiences.
