Interaction Design That Makes Your Interface Feel Alive

Static mockups cannot show how an interface behaves. Interaction design defines what happens when users click, hover, swipe, type, and scroll -- creating the responsive, intuitive feel that separates polished products from frustrating ones.

Interaction Design

Definition and specification of interface behaviors including transitions, animations, feedback patterns, state changes, error handling, and micro-interactions that create polished, intuitive product experiences.

What's Included

Everything you get with our Interaction Design

Interaction Pattern Library

Documented interaction patterns for every common interface behavior: buttons, forms, navigation, modals, tooltips, loading states, and error handling

Micro-Interaction Design

Detailed specifications for subtle animations and feedback that make the interface feel responsive: hover effects, click feedback, progress indicators, and success confirmations

State & Transition Specifications

Complete documentation of all interface states (default, hover, active, disabled, error, loading, success) and the transitions between them

Our Interaction Design Process

Interaction Audit & Pattern Inventory

We audit your current product's interaction patterns, documenting inconsistencies, missing feedback, and behaviors that confuse users. We inventory all interface elements that need interaction specifications.

Pattern Design & Prototyping

We design interaction patterns for each interface element: trigger conditions, visual responses, animation timing, and feedback mechanisms. Interactive prototypes demonstrate each pattern in context so you can evaluate how it feels.

Micro-Interaction Refinement

We refine the subtle animations and feedback that differentiate a polished product from a functional one. Hover effects, loading animations, success confirmations, and transition timing are tuned for the right feel.

Specification & Developer Handoff

We document every interaction pattern with trigger conditions, animation timing (duration, easing), visual states, and code-ready specifications. Developer handoff includes motion files and CSS animation values that ensure accurate implementation.

Key Benefits

Products That Feel Professional and Responsive

Well-designed interactions make your product feel polished. Every click gets immediate feedback. Every transition is smooth and purposeful. Every error is communicated clearly. These subtle behaviors create the perception of quality and reliability that builds user trust and satisfaction.

Reduced User Confusion

Most user confusion comes from unclear interface feedback: did my click register? Is the page loading? Did my form submit? Interaction design ensures every user action produces clear, immediate, and appropriate feedback. When users always know what happened and what to do next, confusion disappears.

Consistent Developer Implementation

Without interaction specifications, developers make their own decisions about behaviors, leading to inconsistent experiences across the product. Our interaction documentation gives developers definitive specifications for every behavior, ensuring the implemented product matches the designed experience exactly.

Frequently Asked Questions

What is the difference between interaction design and visual design?

Visual design determines how things look (colors, typography, imagery). Interaction design determines how things behave (what happens when you click, hover, scroll, or type). Both are essential. A beautiful interface that does not respond to interactions feels dead. A responsive interface that looks amateurish feels untrustworthy.

How detailed do interaction specifications need to be?

Detailed enough for developers to implement without guessing. Each interaction specification includes the trigger (click, hover, scroll), the visual response (what changes), the animation parameters (duration, easing curve), and the end state. We also specify edge cases: what happens on double-click, what happens during loading, what happens on error.

Should every interface element have an animation?

No. Animations should be purposeful: they communicate state changes, provide feedback, guide attention, or ease transitions. Unnecessary animations slow down the interface and distract users. We apply animations where they serve a clear communication purpose and avoid them where they add visual noise.

How do you handle interaction design for accessibility?

Every interaction must work without animation for users who have reduced-motion preferences enabled. Focus states must be visible for keyboard navigation. Interactive elements must have appropriate ARIA labels. We design interactions that enhance the experience for all users while ensuring full functionality for users who cannot perceive animations.
