About the project

Trigger Royale was built for DragonHack 2026 as a phone-based laser-tag game. The camera detects a player beneath the crosshair, extracts a visual embedding, and matches it against registered players so hits can be identified and synchronized during a match.

Technologies used

  • Flutter and Dart for the mobile interface
  • Kotlin and CameraX for native Android camera processing
  • MediaPipe, EfficientDet Lite, and MobileNet V3 for detection and re-identification
  • Python WebSockets for multiplayer communication
