Gesture Response Animations

Apply Disney's 12 principles to direct user interactions.

Principle Application

Squash & Stretch: Elements compress on press (scale 0.95-0.97), spring back on release.

Anticipation : The press IS the anticipation. Response should be immediate - no delay.

Staging : Response originates from interaction point. Ripples expand from tap location.

Straight Ahead vs Pose-to-Pose : Define rest, pressed, and released poses. Transitions flow between them.

Follow Through & Overlapping: Release animation overshoots rest position. Scale to 1.02, settle to 1.0.

Slow In/Slow Out : Press: instant. Release: ease-out with overshoot cubic-bezier(0.34, 1.56, 0.64, 1).

Arcs : Drag elements follow finger with slight lag on curves. Snapping follows arc to destination.

Secondary Action : Press triggers ripple + scale + shadow change simultaneously.

Timing :

• Press response: 0-50ms (must feel instant)
• Release recovery: 150-300ms (can be playful)
• Ripple expansion: 400-600ms (decorative, can be slower)

Exaggeration : Subtle for press (0.97), playful for release (overshoot 1.03).

Solid Drawing : Pressed state should feel "pushed in" - smaller scale, reduced shadow, shifted color.

Appeal : Gestures should feel physically satisfying. Like pressing a real button.

Timing Recommendations

Implementation Patterns

/* Button press */
.button {
  transition: transform 50ms ease-out;
}

.button:active {
  transform: scale(0.97);
}

/* Release with overshoot */
.button:not(:active) {
  transition: transform 250ms cubic-bezier(0.34, 1.56, 0.64, 1);
}

/* Material ripple */
.ripple {
  animation: ripple 600ms ease-out forwards;
}

@keyframes ripple {
  from {
    transform: scale(0);
    opacity: 0.5;
  }
  to {
    transform: scale(4);
    opacity: 0;
  }
}

Drag Feedback Pattern

// Smooth drag with slight lag
element.style.transform = `translate(${x}px, ${y}px)`;
element.style.transition = 'transform 50ms ease-out';

// Snap back with spring
element.style.transition = 'transform 300ms cubic-bezier(0.34, 1.56, 0.64, 1)';
element.style.transform = 'translate(0, 0)';

Critical Rule

Gesture responses must be under 100ms to feel connected to the action. Anything slower breaks the direct manipulation illusion. Test on actual touch devices.
