Designing Hierarchical Exploratory Experiences for Ethnic Costumes: A Cultural Gene-Based Perspective

Ethnic clothing is a vital carrier of cultural identity, yet its digital preservation often results in static displays that fail to convey deep cultural meaning or foster user engagement. Existing practices lack a systematic design framework for translating the hierarchical cultural connotations of these garments into dynamic, personalized, and identity-promoting digital experiences. To address this gap, this paper proposes a Three-Layer Cultural Gene Framework that systematically decodes ethnic costumes from their surface-level visual symbols, through their mid-level socio-cultural contexts, to their inner-layer spiritual core. Based on this framework, we designed and implemented an interactive digital platform featuring two key innovations: a "gene-first" exploratory path that encourages curiosity-driven discovery, and an AI-powered co-creation experience. This generative feature allows users to co-create personalized narratives and images based on their understanding of the "inner-layer" genes, transforming them from passive observers into active co-creators. A mixed-methods user study (N=24) was conducted to evaluate the platform. The findings demonstrate that our approach effectively enhances users' cultural cognition, deepens their affective connection, and significantly promotes their sense of cultural identity. This research contributes a validated framework and a practical exemplar for designing generative, identity-building digital experiences for cultural heritage, offering a new pathway for its preservation and revitalization in the digital age.
