Expo AR Wayfinding is an exploratory research project developed within the Proeftuin Media XR & 5G initiative. The project examined whether browser-based augmented reality (WebAR) could be used as a practical wayfinding solution for large, temporary exhibition environments such as trade fairs.
The goal was to test if visitors could navigate an expo floor using AR directly through their smartphone browser, without installing an app. Several prototypes were tested during live expo conditions, using spatial scanning and visual localisation to guide users along predefined routes with AR direction cues.
Across multiple test phases, the project explored different technical approaches, including large and small spatial scans, multiple localisation zones, and alternative anchoring methods. These experiments revealed both the potential and the current limitations of WebAR navigation in dynamic environments. While basic AR guidance proved possible, the research highlighted challenges related to scan stability, localisation accuracy, changing expo layouts, and inconsistent performance across devices.
The project concludes that browser-based AR wayfinding can be viable in more controlled or static environments, such as museums or permanent venues, but remains difficult to deploy reliably on large, fast-changing expo floors with today’s technology. The findings provide valuable insights for future research into scalable AR navigation systems and help define realistic expectations for WebAR use in public spaces.
