The system includes AR (mobile), VR (immersive), a desktop editor, and a server backend. Experts evaluated proposed features like 360° media, inter-artifact relationships, and interactive object manipulation, highlighting their educational value while calling for improved accessibility and gamification. Results demonstrate how participatory design can align XR innovation with cultural heritage needs, offering guidelines for future development.Attribution 4.0 International LicenseCCS Concepts: Human-centered computing → Mixed / augmented reality; Virtual reality; Human computer interaction (HCI)Human centered computing → Mixed / augmented realityVirtual realityHuman computer interaction (HCI)Co-Designing XR Exhibits: Insights from a Domain Expert Workshop on UI and Interaction Features for Cultural Heritage10.2312/dh.202533445 pages
