AR Chess with Real-time Opponent Detection

 AR Chess with Real-Time Opponent Detection – IT & Computer Engineering Guide

1. Project Overview

The AR Chess with Real-Time Opponent Detection project aims to create an immersive and interactive augmented reality experience where users play chess on a physical surface enhanced through AR glasses or mobile devices. The game utilizes computer vision to detect a real-time opponent, sync movements, and project virtual chess pieces and states.

2. System Architecture Overview

- AR Client: Mobile/AR glasses render chessboard overlay and capture real-world inputs.
- Cloud/Game Server: Manages game state, move validation, and opponent syncing.
- Opponent Detection Module: Vision-based model for identifying real-time player presence and activity.
- Data Flow: Camera feed → Vision analysis → Move update → Sync via server → AR overlay rendered.

5. Computer Vision & Opponent Detection

- Face and pose tracking to detect active player presence.
- Object tracking to recognize physical chess moves.
- ML model (YOLOv8/MediaPipe) for body/gesture recognition.
- Vision module runs in real time and flags opponent move.
- Optional: Gesture-based interaction or eye-gaze triggers.

6. Networking & Game Sync

- WebSocket or Firebase Realtime Database for real-time sync.
- Cloud-hosted server verifies move legality.
- AR device syncs updated board state after move detection.
- Latency optimized under 150ms for real-time experience.

7. Game Logic & Mechanics

- Chess rules engine (custom script or Stockfish integration).
- Board calibration using AR markers or plane detection.
- Projected overlays for pieces, highlights, and timers.
- Undo, pause, save, and resume features for user control.

8. Testing & Optimization

- Test AR alignment with multiple lighting conditions.
- Model tuning for gesture/face detection accuracy.
- Performance profiling (AR FPS > 60)
- Optimize vision model for edge-device inference (TFLite).
- Use GPU acceleration for image tasks where available.

9. Deployment & Maintenance
