In recent years, user experience research has increasingly focused on inclusivity and social equity, especially strategies to enhance the experience of disadvantaged people through accessible design. As a place where different groups of people gather, museum visitors include healthy people and people with cognitive disabilities. Cognitively impaired people have different mental impairments in thinking, memory, attention, etc. Attention to their needs not only enhances the motivation of the public to visit but also improves the quality of social services. However, current museums mainly rely on the exhibition form of text and images, which has limited friendliness to people with cognitive disabilities. Digital storytelling, as an important means of enhancing interaction and sustaining interpersonal relationships, has demonstrated the potential to enhance audience content understanding in exhibition design. Although studies have shown the positive effects of digital narratives on enhancing content understanding in exhibitions, research on how to design storytelling formats for people with cognitive disabilities needs to be further explored to contribute to the goals of inclusiveness and social equity.
