Description

While SkyView has some responsive design elements, the user experience on mobile devices (smartphones and tablets) needs significant improvement. Many users want to track aircraft while outdoors or away from desktop computers, making mobile optimization crucial.

Current Mobile Issues

User Interface Problems

Small Touch Targets: Buttons and controls are too small for finger navigation
Dense Information: Aircraft table rows are cramped on small screens
Map Controls: Zoom/pan controls are not optimized for touch
Text Size: Some text is too small to read comfortably
Horizontal Scrolling: Tables require horizontal scrolling on phones

View Switching: Tab navigation could be more thumb-friendly
Menu Access: Settings and options are hard to reach on mobile
Modal Dialogs: Popups don't fit well on small screens
Keyboard Issues: Virtual keyboard covers content when typing

Performance Issues

Map Rendering: Leaflet map performance on mobile browsers
WebSocket Updates: Potential battery drain from constant updates
Memory Usage: Large aircraft datasets can slow mobile browsers
Touch Responsiveness: Delays in touch interactions

Proposed Mobile Enhancements

Responsive Design Improvements

Mobile-First CSS: Redesign with mobile as primary target
Touch-Friendly Controls: Larger buttons (44px minimum touch target)
Simplified Layouts: Stack elements vertically on small screens
Readable Typography: Increase font sizes for mobile viewing
Thumb Navigation: Position important controls in thumb-reach zones

Mobile-Specific Features

Swipe Gestures:
- Swipe between different views (Map, Table, Stats)
- Swipe to refresh aircraft data
- Pull-to-refresh functionality
Touch Optimizations:
- Long-press for detailed aircraft info
- Pinch-to-zoom on map
- Touch-friendly aircraft selection
Mobile Menu: Collapsible hamburger menu for options
Bottom Sheet UI: Use bottom sheets instead of traditional modals

Performance Optimizations

Progressive Loading: Load aircraft data incrementally
Virtual Scrolling: For large aircraft tables
Reduced Updates: Configurable update rates to save battery
Offline Capabilities: Cache data for brief offline viewing
Image Optimization: Optimized icons and graphics for mobile

Implementation Approach

CSS/Media Query Strategy

/* Mobile First */
.aircraft-table {
  font-size: 16px;
  line-height: 1.4;
}

/* Tablet */
@media (min-width: 768px) {
  .aircraft-table {
    font-size: 14px;
    display: grid;
    grid-template-columns: repeat(auto-fit, minmax(200px, 1fr));
  }
}

/* Desktop */
@media (min-width: 1024px) {
  .aircraft-table {
    display: table;
    font-size: 13px;
  }
}

JavaScript Touch Handling

// Touch gesture support
let startX, startY;
mapContainer.addEventListener('touchstart', (e) => {
  startX = e.touches[0].clientX;
  startY = e.touches[0].clientY;
});

mapContainer.addEventListener('touchend', (e) => {
  const endX = e.changedTouches[0].clientX;
  const deltaX = endX - startX;
  
  if (Math.abs(deltaX) > 100) {
    // Swipe gesture detected
    handleSwipeGesture(deltaX > 0 ? 'right' : 'left');
  }
});

PWA Enhancements

App Manifest: Make SkyView installable as PWA
Service Worker: Cache resources for offline access
App Icons: Provide various icon sizes for different devices
Splash Screen: Custom loading screen for installed app
Fullscreen Mode: Immersive aircraft tracking experience

Testing Strategy

Device Testing
