- 1Mapping: Model the indoor map as a navigation graph with nodes and walkable edges.
- 2Positioning: Estimate position using AR markers/anchors and device sensors (visual-inertial).
- 3Routing: Compute shortest paths and project AR directional arrows onto the camera view.
- 4POIs: Add searchable points of interest and turn-by-turn guidance.
Key features to implement
- ✓AR turn-by-turn arrows
- ✓Indoor positioning
- ✓POI search
- ✓Shortest-path routing
- ✓Multi-floor support
💡 Unique twist to stand out
Add accessibility routing that prefers elevators/ramps and announces directions via audio for visually impaired users.
