Performance Optimization for Touch

Touch Event Optimization

Touch Event Handling

5 steps for optimal touch performance

  1. Optimize event listeners → 2. Use passive events → 3. Implement debouncing → 4. Touch-action CSS → 5. Measure performance

Performance Tips:

  • Use passive event listeners
  • Touch-action CSS for better performance
  • Use event delegation
  • Avoid unnecessary touch events

Lazy Loading for Touch Devices

Tip: Lazy loading significantly improves touch performance

Touch-optimized Lazy Loading:

  • Use Intersection Observer
  • Consider touch gestures
  • Preloading with swipe gestures
  • Implement progressive enhancement

Accessibility and Touch

WCAG Guidelines for Touch

Touch Accessibility

6 points for accessible touch interaction

  1. Minimum size 44x44px for all touch targets
  2. Sufficient contrast (4.5:1 minimum)
  3. Keyboard navigation as alternative
  4. Make focus indicators visible
  5. Document touch gestures
  6. Ensure screen reader compatibility

Touch Navigation for Screen Readers

Important ARIA Attributes:
