Interaction Design
The feeling of using a product is determined by its interactions — how elements animate, respond, and transition. We design interactions that are purposeful, performant, and perceptually satisfying.
// Key benefits
What makes this service valuable
Purposeful micro-interactions
Loading states, success animations, error feedback, and hover effects are opportunities to communicate and delight. We design every state transition with intention.
Performance-aware motion
Heavy animations kill performance and accessibility. Every motion we specify is designed with duration, easing, and reduced-motion alternatives that engineers can implement without compromising Core Web Vitals.
Prototype-level fidelity
Interaction design is specified through high-fidelity Figma prototypes and detailed animation specs — not vague descriptions that engineers have to interpret.

Making products feel alive
Interaction design sits between UI design and engineering — it is the specification of how things move, respond, and communicate through animation and motion. When done well, it is invisible: users feel a sense of quality without being able to articulate why.
We design interactions using a motion system — consistent easing curves, duration scales, and animation principles that create coherence across the product. This system is documented for engineering use with Framer Motion, CSS animations, or platform-native animation frameworks.
// What this includes
- Motion system definition (easing, duration scale, principles)
- Micro-interaction design for all interactive states
- Page and screen transition design
- Loading, empty, and skeleton state animations
- Gesture-driven interaction design (swipe, pinch, drag)
- Reduced-motion alternatives for accessibility
- Engineering specification with animation values

// FAQ
Common questions about interaction design
How do interaction design specs get handed off to engineering?+
We provide Figma Smart Animate prototypes showing intended behaviour, plus a written specification with duration values, easing curves, and trigger conditions. Where helpful, we provide reference implementation snippets in Framer Motion or CSS.
Do you design for prefers-reduced-motion?+
Yes — reduced-motion is a design constraint, not an engineering concern. Every animation we specify has a reduced-motion alternative that removes or minimises motion while preserving functional feedback.
Can interaction design be added to an existing design system?+
Yes — adding a motion layer to an existing design system is a common engagement. We audit current animation use, define motion principles, and extend the design system with interaction documentation.
