Arrow - Posture Monitoring System

Overview

Arrow is a real-time posture monitoring application that uses computer vision to analyze your sitting posture and provides feedback through desktop notifications. This repository contains both the original Iced-based implementation and a modern Tauri migration.

Architecture

Current Implementations

• client/ - Original Rust desktop application using Iced GUI framework
• arrow-client/ - ✨ New Tauri-based application with React frontend
• server/ - Python server for computer vision processing using MediaPipe

System Components

1. Python Server (server/main.py)

   • Real-time webcam capture using OpenCV
   • Pose detection using Google MediaPipe
   • TCP server broadcasting posture metrics

2. Tauri Client (arrow-client/)

   • Backend: Rust with Tauri framework
   • Frontend: React with TypeScript
   • Features: Real-time posture display, notifications, session logging

3. Original Iced Client (client/)

   • Legacy Rust GUI application
   • Preserved for reference and comparison

Migration Status: ✅ COMPLETE

The Tauri migration has been successfully completed with all original features preserved and enhanced:

✅ Core Features Migrated

• Real-time posture monitoring via TCP connection
• Desktop notifications for posture changes
• SQLite session logging and history
• Visual posture feedback with SVG icons
• Automatic server reconnection
• Cross-platform compatibility

✅ Enhancements Added

• Modern React-based user interface
• Enhanced error handling and user feedback
• Improved session history visualization
• Responsive design and better styling
• Comprehensive testing suite
• Better code organization and maintainability

Quick Start

Prerequisites

• Rust (latest stable)
• Node.js v18+
• Python 3 with mediapipe and opencv-python

Run the Tauri Application

# 1. Start the Python server
cd server
pip3 install -r requirements.txt
python3 main.py

# 2. Run the Tauri application
cd arrow-client
npm install
npm run tauri dev

Testing Without Camera

Use the provided test server for development:

# Terminal 1: Test server (simulates posture data)
python3 test_server.py

# Terminal 2: Tauri application
cd arrow-client && npm run tauri dev

Technical Highlights

Event-Driven Architecture

The Tauri migration implements a robust event system:

• posture-update - Real-time posture data
• connection-status - TCP connection state
• session-logs-updated - Database updates
• notification-triggered - Desktop notifications

Modern UI Components

• PostureDisplay: SVG-based visual feedback
• ConnectionIndicator: Real-time status with manual refresh
• SessionHistory: Interactive posture log with duration tracking

Enhanced Error Handling

• Graceful connection failures and retries
• User-friendly error messages
• Proper cleanup on application close
• Memory leak prevention

Documentation

• CLAUDE.md - Complete migration plan and architecture decisions
• TESTING.md - Comprehensive testing guide and verification steps
