Build an AR Navigation App for Campuses
Create an augmented reality mobile app that overlays navigation directions on the user’s real-world camera feed to guide them around campuses or buildings—a highly useful and innovative app development idea.New students, visitors, and event attendees often struggle to find specific rooms or facilities in large campuses. This AR-based app development project helps users find paths visually by overlaying 3D arrows and directions onto the real world using their phone camera.
Users open the app, select a destination (e.g., cafeteria, lecture hall), and follow real-time directional cues superimposed on their camera view. It works using geolocation outdoors and indoor waypoints with QR codes, Wi-Fi, or BLE beacons.
AR Wayfinding with Camera Overlay
Use AR to place virtual arrows and markers on the ground as the user moves toward their destination.
Location Selector and Search
Let users search buildings, rooms, or events and get navigation from their current position.
Indoor Navigation Support
Integrate with indoor location systems like Wi-Fi triangulation, BLE beacons, or QR waypoint scanning.
Campus Map and Offline Access
Provide a fallback 2D map with offline route display when AR is unavailable or GPS signal is weak.
The user launches the camera, selects a destination, and the app calculates the best path. It overlays directional cues using AR and continuously updates directions as the user walks. Indoors, it relies on location anchors or QR-based checkpoints.
- User opens the app and selects a location on campus from a searchable list.
- The app identifies the user's current position using GPS or indoor positioning methods.
- ARCore or ARKit anchors virtual arrows and markers to the real world to guide navigation.
- As the user moves, the app updates the overlays dynamically and helps them stay on route.
- Fallback maps or instructions are shown when AR is not accessible (e.g., in low light or underground).
Frontend
Flutter or React Native with AR plugin wrappers and camera + overlay support.
AR Toolkit
ARCore (Android), ARKit (iOS), or Unity with Vuforia for cross-platform AR rendering.
Location Services
GPS for outdoor navigation, Wi-Fi RTT / BLE Beacons / QR code tracking for indoor accuracy.
Optional Backend
Firebase or Supabase to store campus maps, location metadata, and destination lists.
1. Integrate AR and Camera View
Set up camera feed and add anchors using ARCore/ARKit or Unity to support object placement.
2. Build the Navigation UI
Create location selector, search bar, and UI to show estimated route, time, and steps.
3. Develop Pathfinding Logic
Use Dijkstra or A* algorithm on a campus graph to generate shortest paths between points.
4. Anchor Directions in AR View
Render arrows and signs along the path with location updates and motion tracking.
5. Add Indoor Support
Use QR codes or BLE beacons as position markers to allow accurate indoor routing and AR guidance.
