Place Finder — Gamified Location Discovery & AR Experience

01 . The Challenge

Place Finder transforms everyday location discovery into an interactive city exploration experience. Inspired by location-based games, users can discover nearby Spots, explore 3D characters, complete on-site missions and collect rewards through GPS, AR and camera interactions.

Place Finder is a mobile-first interactive experience designed to connect digital content, physical locations and user exploration through real-world interaction. The experience uses MapLibre to present a simplified 3D city map with GPS-based Spot discovery, while each location can unlock a unique 3D character and mission. Instead of simply browsing a list of restaurants, attractions or activities, users are encouraged to physically explore nearby locations. After reaching a Spot, they can interact with a 3D character, launch an AR camera experience, place or discover the character in the real environment, take a photo and complete the mission. The project was developed as a flexible campaign platform, allowing different locations, characters, rewards, categories and interaction mechanics to be configured through data rather than rebuilding the experience for every campaign.

  1. Accurate GPS Spot Positioning
    Keep Spot markers accurately aligned during zoom, pan, rotation and 3D map movement.
  2. Game-Like 3D Map
    Simplify map details to create a cleaner, more game-like exploration
  3. Mobile 3D Performance
    Load lightweight Spot icons first and full 3D models only when needed.
  4. Cross-Device AR Compatibility
    Support different AR methods and fallbacks across Android and iOS devices.
  5. Stable 3D Character Animation
    Remove root motion so the UU Bear can walk naturally in place.
  6. Mission-Based Exploration
    Turn physical visits into interactive missions through 3D, AR and photography.
  7. Campaign Scalability
    Use configurable Spot data so campaigns can be updated without rebuilding the platform.

02 . The Solution

A modular mobile web experience was created using Vue 3, MapLibre and Three.js. GPS data connects users with nearby Spots, while a simplified 3D map provides a game-like exploration interface. Each Spot supports configurable 3D models, mission content, interaction ranges and rewards. Multiple AR approaches were prototyped—including QR tracking, A-Frame marker tracking and browser-based markerless placement—to identify a practical balance between device compatibility, visual immersion and performance. The final architecture keeps map exploration lightweight while loading richer 3D and AR experiences only when users enter a Spot. Mission completion can also require an AR photo interaction, turning a digital map visit into a measurable real-world engagement action.
