Project Type: Mobile Application (iOS/Android)

Role: Lead Mobile Engineer & Product Architect

Objective: Create a travel navigation tool that uses Augmented Reality to make city exploration safer and more intuitive for users of all abilities.

Scope: AR Implementation, Geolocation Services, Accessibility Engine, UI/UX Design.

Traditional 2D maps are often abstract and difficult to interpret in real-time, especially for users with cognitive or visual impairments. Navigating a bustling city like Lagos or New York requires more than just a blue dot on a screen.

The challenge was to build a navigation system that wasn't just visually impressive, but functionally inclusive allowing users to customize the interface based on their specific visual, auditory, or motor needs.

I architected a mobile solution that merges camera-based navigation with a robust personalization engine.

Augmented Reality (AR) Pathfinding Instead of a flat map, the app uses the phone's camera to overlay a green navigation path onto the real world. I implemented ARKit/ARCore to anchor 3D directional arrows to real-world coordinates, helping users visualize exactly where to turn.

The Accessibility Engine This is the core differentiator. Unlike standard apps, this platform begins with a "Needs Assessment." I engineered a settings module that allows users to toggle:

Location-Aware Context The app dynamically adapts to the user's city. Whether in Lagos or New York, the backend fetches real-time POI (Point of Interest) data to categorize locations into "Nightlife," "Shopping," or "Restaurants" with crowd-density indicators.

Geolocation Accuracy: Implemented sensor fusion (GPS + Compass + Accelerometer) to ensure AR overlays remain stable and accurate while walking.

State Management: Managed complex user preference states (font size, color schemes, audio settings) globally to ensure the entire app adapts instantly to the user's profile.

Performance: Optimized 3D rendering to run at 60fps on mobile devices without excessive battery drain.

This project demonstrates the future of inclusive technology:

✅ Universal Design: A single codebase serving both standard users and those with disabilities.

⚡ Immersive Tech: Successfully bridging the gap between digital maps and physical reality.

🌍 Global Scalability: Architecture ready to support navigation data for any major city worldwide.
