From Spatial Representation to Participatory Engagement: Designing a UCD–BDD Virtual Pilgrimage Environment

This study addresses the impact of pandemics, economic limitations, and physical constraints on physical pilgrimage by proposing and evaluating a culturally sensitive, ritual-oriented virtual Boudhanath Stupa environment. Using user-centered design (UCD) and Behavior-Driven Development (BDD), the project created interactive ritual nodes on a Minecraft–VR platform, combining spatial configuration, symbolic elements, and exploratory freedom to move beyond static representation toward participatory engagement. A mixed-methods evaluation with 50 participants from diverse backgrounds and 2 Tibetan Buddhist experts showed positive feedback for aesthetic experience (M = 4.36) and user control (M = 4.62). Despite its non-photorealistic style, the environment was able to evoke a strong sense of presence and was recognized by experts as a “digital Dharma gate” suitable for younger audiences and those unable to travel to sacred sites. Limitations include a small sample size, a short evaluation period, and a lack of social interaction features. Future development will enhance guidance and feedback, expand narratives, support community co-creation, and introduce multi-user functions, providing a scalable framework for virtual religious cultural heritage.
