Developed a browser-based augmented reality prototype inspired by the traditional Japanese Kingyo Sukui (Goldfish Scooping) festival game.
The project was designed as a location-based multiplayer experience where multiple players share the same virtual environment in real time. Rather than each device running an independent game, all participants interact with a synchronized set of virtual goldfish, requiring low-latency networking and consistent state management across devices.
Responsibilities
Designed and implemented the browser-based WebAR experience
Developed real-time multiplayer synchronization
Implemented marker-based spatial alignment
Built motion-based interaction mechanics using mobile device sensors
Created responsive gameplay systems for synchronized scoring and game flow
Optimized the experience for Android mobile browsers
Technologies
TypeScript
JavaScript (ES Modules)
Three.js
WebAR
WebSockets
HTML5 / CSS3
Mobile browser APIs (Camera, Device Orientation, Device Motion)
Highlights
Browser-based AR experience with no native app installation
Shared multiplayer game state across multiple devices
Real-time synchronization over local Wi-Fi
Motion-based gameplay using smartphone sensors
Interactive 3D graphics and animation
Production-oriented modular architecture

Results
The project demonstrates the integration of real-time networking, computer graphics, browser-based augmented reality, and interactive user experience design for location-based entertainment applications.
