What this skill tells the agent

Universal Emotion Animation Framework

Map Disney's 12 principles to any emotional goal through systematic analysis.

Emotional Goal

Any emotion can be achieved through intentional application of animation principles. This framework helps translate emotional intent into specific motion parameters.

Emotion Mapping Framework

Step 1: Define the Emotion

Identify your target on these spectrums:

  • Energy: Low ←→ High
  • Valence: Negative ←→ Positive
  • Arousal: Calm ←→ Excited
  • Dominance: Submissive ←→ Powerful

Step 2: Map Principles to Emotion

Step 3: Select Easing

Quick Reference by Emotion

Positive Emotions

  • Joy: Fast timing, high squash/stretch, bouncy easing
  • Trust: Consistent timing, minimal deformation, smooth easing
  • Calm: Slow timing, subtle movement, symmetric easing
  • Excitement: Fast timing, high energy, dynamic easing

Functional Emotions

  • Urgency: Very fast, direct paths, attention-grabbing
  • Professional: Moderate timing, minimal decoration, standard easing
  • Friendly: Moderate timing, soft deformation, gentle easing

Premium Emotions

  • Elegant: Slower timing, no deformation, refined easing
  • Powerful: Deliberate timing, impact emphasis, strong easing

CSS Variables Template

:root {
  /* Adjust based on target emotion */
  --emotion-duration: 300ms;
  --emotion-easing: cubic-bezier(0.4, 0, 0.2, 1);
  --emotion-squash: 1;
  --emotion-overshoot: 0;
}

Decision Tree

  1. Is the emotion high or low energy?
  2. Is the feeling positive, negative, or neutral?
  3. Should users feel in control or guided?
  4. Is this a moment or a state?
  5. What's the brand personality?

Combining Emotions

Real experiences blend emotions. Layer principles:

  • Primary emotion: 70% influence
  • Secondary emotion: 30% influence
  • Adjust timing/easing accordingly

When to Use

  • Novel emotional requirements
  • Brand-specific interpretations
  • Complex emotional journeys
  • A/B testing emotional impact
  • Cross-cultural considerations
  • Accessibility adaptations
