Abstract—ARWay is an Augmented Reality (AR) campus navigation system built on Unity 3D, ARCore Geospatial API, and Google AR Foundation. The system fuses live GPS geospatial positioning with a deterministic Dijkstra-based shortest-path algorithm operating over a hand-authored campus node graph, projecting a single 3D directional arrow into the physical world that re-orients every frame toward the next routing waypoint. This paper documents the full engineering stack: Haversine distance computation, geodetic bearing mathematics, the ScriptableObject-based embedded location data model, the ARCore EUN coordinate-frame binding strategy, and the rationale for single-arrow AR guidance. A prototype deployed on campus demonstrated real-time GPS-locked navigation with ±4.4 m horizontal accuracy at 22.29° N, 73.36° E.
