Traditional cultural heritage exhibitions primarily rely on static 3D models and 2D interactive displays, which often struggle to convey the kinetic intricacies and the cultural depth of artifacts, particularly in the digitization of traditional garments. These conventional methods lack the ability to convey the fluidity of fabric movement and the immersive sense of wearing garments. To address these challenges, we collaborated with the Hong Kong Museum of Art (HKMoA) to develop The Reality of Silk, an augmented reality (AR) try-on system featuring an integrated exhibition environment that enables real-time full-body virtual try-on and virtual runway show, providing users with an immersive cultural experience enhanced with multisensory cues. Built on a lightweight, cross-platform framework, the system integrates industrial digital fashion tools, establishing a rapid digitization pipeline that transforms diverse designer-created Chinese costumes into interactive try-on experiences. This approach enables the swift deployment of digital garments across multiple platforms, extending beyond museum installations. By incorporating digital fashion technologies within an AR-driven exhibition space, our system offers a more immersive, interactive, and widely accessible user experience.
