Large college campuses are often difficult to navigate, especially for new students and visitors. GPS works well outdoorsbutisunreliable inside buildings. To address this, we developed a Hybrid Progressive Web App (PWA) that combines outdoor GPSnavigationwith indoor QR-based checkpoint tracking. GPS is used for campus-level guidance, while indoor navigation is performedbyscanningQR codes placed at key locations or by manually selecting the current position. Each QR code represents a node in a pre-modeledindoorgraph, enabling shortest-path routing using algorithms such as Dijkstra or A*. The system also detects route deviations andautomaticallyrecalculates the route when a new location is confirmed. The application supports start/stop navigation sessions and canfunctionofflineafter initial installation, providing a reliable and scalable solution for campus navigation.
