Accessibility Issues

Make animations inclusive using Disney's principles thoughtfully.

Problem Indicators

  • Motion sickness complaints
  • Vestibular disorder triggers
  • Screen reader confusion
  • Cognitive overload
  • Seizure risk (flashing)
  • Keyboard focus lost during animation

Diagnosis by Principle

Squash and Stretch

Issue: Excessive distortion causes disorientation Fix: Reduce or eliminate squash/stretch for users with prefers-reduced-motion. Use opacity changes instead.

Secondary Action

Issue: Too many moving elements Fix: Limit to one animated element at a time. Secondary actions should be subtle or removed.

Exaggeration

Issue: Dramatic motion triggers vestibular responses Fix: Reduce scale, rotation, and position changes. Keep movements small and predictable.

Timing

Issue: Animations too fast or too slow Fix: Provide consistent, predictable timing. Avoid sudden speed changes.

Arcs

Issue: Curved motion paths cause tracking difficulty Fix: Use linear motion for essential UI. Save arcs for optional decorative elements.

Quick Fixes

  1. Respect prefers-reduced-motion - Always check and honor
  2. No autoplay animation - Let users trigger motion
  3. Keep focus visible - Never animate focus indicator away
  4. Announce changes - Use ARIA live regions for dynamic content
  5. Provide pause controls - For any looping animation

Troubleshooting Checklist

  • Does animation respect prefers-reduced-motion?
  • Is there a way to pause/stop animations?
  • Are state changes announced to screen readers?
  • Does keyboard focus remain visible and logical?
  • Is flash rate under 3 per second?
  • Can users complete tasks without animation?
  • Are animations triggered by user action (not autoplay)?
  • Test with screen reader enabled

Code Pattern

@media (prefers-reduced-motion: reduce) {
  *,
  *::before,
  *::after {
    animation-duration: 0.01ms !important;
    animation-iteration-count: 1 !important;
    transition-duration: 0.01ms !important;
  }
}
// Check preference in JS
const prefersReducedMotion = window.matchMedia(
  '(prefers-reduced-motion: reduce)'
).matches;
