📖 Overview

SpectraX is a full-stack fitness application that uses MediaPipe Pose Detection, Three.js, and WebSockets to deliver real-time workout tracking, intelligent form analysis, and immersive 3D body visualization — entirely in the browser.

It doesn't just track your body; it understands your movement. SpectraX counts reps, detects which exercise you're performing, scores your form, identifies anomalies with ML algorithms, and renders a live 3D skeleton that mirrors your every move.

Why SpectraX?

Requires wearable hardware	Uses only a webcam
Basic step/heart-rate counting	Intelligent rep counting with form scoring
Manual exercise logging	Auto-detects exercise type via AI
2D dashboards	Real-time 3D body skeleton visualization
No posture feedback	Real-time posture correction & anomaly detection

Data Flow

📷 Capture — Camera frames are captured in real time via the browser's MediaDevices API
🦴 Pose Estimation — MediaPipe Pose extracts 33 body landmarks with 3D coordinates
📐 Angle Calculation — Joint angles are computed using landmark coordinates (with optional GPU-accelerated calculations)
🤖 Exercise Classification — AI logic auto-detects the current exercise using the activity classification service
🔢 Rep Counting — State-machine-based algorithms track movement cycles with depth classifiers per exercise
🎯 Form Scoring — Posture accuracy is evaluated in real time; anomaly detection flags deviations post-session
🎥 3D Rendering — Three.js renders a live skeleton with volumetric fog and biomechanical stress shaders
⚡ Sync — Socket.io synchronizes workout data between client and server with auth, rate limiting, and CORS hardening

🚀 Quick Start

Prerequisites: Node.js v18.x or higher, npm

# 1. Clone the repository
git clone https://github.com/Somil450/spectrax_1.git
cd spectrax_1

# 2. Install frontend dependencies
npm install

# 3. Install backend dependencies
cd server && npm install && cd ..

# 4. Set up environment variables (see below)

# 5. Start the backend (Terminal 1)
cd server && npm run dev

# 6. Start the frontend (Terminal 2)
npm run dev

The frontend runs at http://localhost:5173 and the backend at http://localhost:3001.

🔐 Environment Variables

Frontend (`.env` in project root)

Copy .env.example and fill in your Firebase credentials:

# Firebase Configuration (from Firebase Console)
VITE_FIREBASE_API_KEY=your_api_key_here
VITE_FIREBASE_AUTH_DOMAIN=your_project.firebaseapp.com
VITE_FIREBASE_PROJECT_ID=your_project_id
VITE_FIREBASE_STORAGE_BUCKET=your_project.appspot.com
VITE_FIREBASE_MESSAGING_SENDER_ID=your_sender_id
VITE_FIREBASE_APP_ID=your_app_id

# Firebase App Check — reCAPTCHA Enterprise site key (optional, leave empty for local dev)
VITE_APPCHECK_RECAPTCHA_KEY=

# Backend URL (client derives WebSocket URL by swapping http → ws)
VITE_BACKEND_URL=http://localhost:3001

Backend (`.env` in `server/` directory)

PORT=3001
ALLOWED_ORIGIN=http://localhost:5173

⚠️ Never commit .env files to version control. The .env.example file is provided as a template.

Firebase Setup

Create a project at Firebase Console
Enable Authentication (Email/Password provider)
Create a Firestore database
Copy your project config into the .env file
Deploy Firestore security rules:

npm install -g firebase-tools
firebase login
firebase deploy --only firestore:rules

Without deploying these rules, the project runs in Firebase test mode (open access). Always deploy them before going to production.

💻 Usage

Workout Flow

Welcome — Choose an exercise or let SpectraX auto-detect it
Calibration — Align yourself with the camera for optimal pose tracking
Workout — Exercise in real time! Watch reps count up, form scores update, and your 3D skeleton mirror your movement
Summary — Review detailed post-workout analytics: rep streaks, duration, calorie burn, accuracy breakdown, and AI-generated improvement tips
Replay — Re-watch your session in full 3D with biomechanical stress overlays

📊 Performance

Metric	Value
Pose Detection FPS	~30 FPS
Rep Counting Accuracy	~94%
Detection Latency	<100ms
Supported Resolution	720p / 1080p
Pose Landmarks	33 Keypoints (3D)
Web Workers	2 (pose + activity classification)

Performance varies by device hardware, lighting conditions, and camera quality. The built-in FPS monitor and adaptive throttle service help maintain smooth performance on lower-end devices.

📱 Browser Compatibility

Browser	Support
Chrome (Desktop)	✅ Full Support
Edge	✅ Full Support
Firefox	✅ Full Support
Android Chrome	✅ Full Support
Safari / iOS	⚠️ Experimental

Note: SpectraX requires SharedArrayBuffer support (via Cross-Origin-Opener-Policy and Cross-Origin-Embedder-Policy headers), which is configured automatically in both the Vite dev server and Vercel deployment.

🧪 Testing

# Run frontend tests
npm test

# Run tests in watch mode
npm run test:watch

# Run tests with coverage
npm run test:coverage

# Run lint checks
npm run lint

# Run backend tests
cd server && npm test

The project uses Vitest with jsdom for frontend tests and React Testing Library for component testing. The backend uses Vitest with Supertest for HTTP endpoint testing.

CI runs automatically on push/PR to main via GitHub Actions, testing against Node 20.x and 22.x.

🚢 Deployment

Frontend (Vercel)

The project includes a vercel.json with:

SPA rewrites (all routes → index.html)
Required COOP/COEP headers for SharedArrayBuffer
Service worker cache control

Deploy with:

npx vercel

Backend

The backend is a standalone Express + Socket.io server. Deploy to any Node.js-compatible platform (Railway, Render, Fly.io, etc.) and set the ALLOWED_ORIGIN env var to your frontend URL.

🗺️ Roadmap

AI-based calorie estimation improvements
Multi-person pose tracking
Voice-guided workout assistant
Native mobile application
Cloud workout history sync
Workout recommendation engine
Advanced analytics dashboard with charts
Social features (workout sharing, leaderboards)
