WiFi DensePose UI

A modular, modern web interface for the WiFi DensePose human tracking system. This UI provides real-time monitoring, configuration, and visualization of WiFi-based pose estimation.

🏗️ Architecture

The UI follows a modular architecture with clear separation of concerns:

🛠️ Usage

Basic Setup

<!DOCTYPE html>
<html>
<head>
    <link rel="stylesheet" href="style.css">
</head>
<body>
    <div class="container">
        <!-- Your content -->
    </div>
    <script type="module" src="app.js"></script>
</body>
</html>

Using Services

import { poseService } from './services/pose.service.js';
import { healthService } from './services/health.service.js';

// Get current pose data
const poseData = await poseService.getCurrentPose();

// Subscribe to health updates
healthService.subscribeToHealth(health => {
    console.log('Health status:', health.status);
});

// Start pose streaming
poseService.startPoseStream({
    minConfidence: 0.7,
    maxFps: 30
});

poseService.subscribeToPoseUpdates(update => {
    if (update.type === 'pose_update') {
        console.log('New pose data:', update.data);
    }
});

Using Components

import { TabManager } from './components/TabManager.js';
import { DashboardTab } from './components/DashboardTab.js';

// Initialize tab manager
const container = document.querySelector('.container');
const tabManager = new TabManager(container);
tabManager.init();

// Initialize dashboard
const dashboardContainer = document.getElementById('dashboard');
const dashboard = new DashboardTab(dashboardContainer);
await dashboard.init();

🔧 Configuration

API Configuration

Edit config/api.config.js to modify API settings:

export const API_CONFIG = {
  BASE_URL: window.location.origin,
  API_VERSION: '/api/v1',
  
  // Rate limiting
  RATE_LIMITS: {
    REQUESTS_PER_MINUTE: 60,
    BURST_LIMIT: 10
  },
  
  // WebSocket configuration
  WS_CONFIG: {
    RECONNECT_DELAY: 5000,
    MAX_RECONNECT_ATTEMPTS: 5,
    PING_INTERVAL: 30000
  }
};

Authentication

import { apiService } from './services/api.service.js';

// Set authentication token
apiService.setAuthToken('your-jwt-token');

// Add request interceptor for auth
apiService.addRequestInterceptor((url, options) => {
    // Modify request before sending
    return { url, options };
});

🎨 Styling

The UI uses a comprehensive CSS design system with:

• CSS Custom Properties for theming
• Dark/light mode support
• Responsive design
• Component-based styling
• Smooth animations and transitions

Key CSS Variables

:root {
  --color-primary: rgba(33, 128, 141, 1);
  --color-background: rgba(252, 252, 249, 1);
  --color-surface: rgba(255, 255, 253, 1);
  --color-text: rgba(19, 52, 59, 1);
  --space-16: 16px;
  --radius-lg: 12px;
}

🔍 Monitoring & Debugging

Health Monitoring

import { healthService } from './services/health.service.js';

// Start automatic health checks
healthService.startHealthMonitoring(30000); // Every 30 seconds

// Check if system is healthy
const isHealthy = healthService.isSystemHealthy();

// Get specific component status
const apiStatus = healthService.getComponentStatus('api');

Error Handling

// Global error handling
window.addEventListener('error', (event) => {
    console.error('Global error:', event.error);
});

// API error handling
apiService.addResponseInterceptor(async (response, url) => {
    if (!response.ok) {
        console.error(`API error: ${response.status} for ${url}`);
    }
    return response;
});

🚀 Deployment

Development

Option 1: Use the startup script

cd /workspaces/wifi-densepose/ui
./start-ui.sh

Option 2: Manual setup

# First, start your FastAPI backend (runs on port 8000)
wifi-densepose start
# or from the main project directory:
python -m wifi_densepose.main

# Then, start the UI server on a different port to avoid conflicts
cd /workspaces/wifi-densepose/ui
python -m http.server 3000
# or
npx http-server . -p 3000

# Open the UI at http://localhost:3000
# The UI will automatically detect and connect to your backend

Backend Detection Behavior

• Real Backend Available: UI connects to http://localhost:8000 and shows ✅ "Connected to real backend"
• Backend Unavailable: UI automatically uses mock server and shows ⚠️ "Mock server active - testing mode"
• Force Mock Mode: Set API_CONFIG.MOCK_SERVER.ENABLED = true for testing

Production

1. Configure API_CONFIG.BASE_URL for your backend
2. Set up HTTPS for WebSocket connections
3. Configure authentication if required
4. Optimize assets (minify CSS/JS)
5. Set up monitoring and logging

🤝 Contributing

1. Follow the modular architecture
2. Add tests for new functionality
3. Update documentation
4. Ensure TypeScript compatibility
5. Test with mock server
