Physical wayfinding systems communicate basic spatial information, but they often fail to address real-time safety risks. During field research, we observed transfer areas where passengers must cross train tracks and rely on their senses to judge whether it is safe to cross, a situation that poses serious risks for people with sensory impairments.

To address this limitation, we explored digital tools as an assistive layer that complements physical wayfinding. By providing real-time safety alerts through audio and vibration and guiding users toward safer routes, AR helps make invisible risks more perceptible. We created a short video prototype to demonstrate how virtual guidance can extend physical wayfinding to better support diverse users.
