SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Designs and codifies motion systems for web interfaces to standardize animation tokens and behavior, reducing guesswork and debt while enabling cross-project consistency.

Core Features & Use Cases

  • Standardizes motion tokens: easing curves, durations, and timing functions for all components.
  • Builds a scalable motion system across design tokens and product surfaces (modal, dropdown, tooltip, navigation transitions).
  • Performs performance and accessibility reviews to prevent vestibular discomfort and jank; use when introducing new components or refining existing motion.

Quick Start

Describe a UI interaction and I will output a complete motion plan with tokens and example implementations.

FAQPage Schema
How do I create a motion token system for UI animations?

To create a motion token system for UI animations, you standardize easing curves, durations, and transform constraints. This ensures cross-project consistency and reduces design debt by formalizing motion behavior across component libraries.

How do I standardize animation durations and easing curves across a design system?

Standardizing animation durations and easing curves involves defining formal motion tokens applied across all product surfaces. This process scales motion design systematically across modals, dropdowns, and navigation transitions while preventing visual jank.

Can I use motion tokens with React, Vue, and vanilla JS interfaces?

Yes, you can apply motion tokens across React, Vue, and vanilla JS interfaces. The formalized easing curves and duration constraints are designed to integrate into component libraries and product experiences across these web frameworks.

What is the best way to prevent vestibular discomfort and jank in web animations?

The best way to prevent vestibular discomfort and jank is by performing accessibility and performance reviews on your motion tokens. Constraining transforms and standardizing timing functions ensures smooth, accessible UI animations without causing visual discomfort.

Why does my UI animation behavior lack consistency across different components?

UI animation behavior lacks consistency when motion tokens are not formally codified. Without standardized easing curves, durations, and transform constraints, guesswork introduces design debt and fragmented motion behavior across your component library.
