Product Design & UI/UX

Interaction Design

Make every action clear: feedback when users tap, progress while they wait, help when something fails. Interactions and motion designed for usability and accessibility.

Who brings us interaction work

The screens look finished, but how each control responds was left to whoever built it, so double submits, silent saves and dead-end errors reach users. Interaction design decides that behavior, once, before more of it is built.

  • Mobile teams adding swipe, drag or offline behavior to an existing app
  • SaaS teams with long-running imports, exports or report jobs
  • Teams running payment, booking or checkout flows where a repeated action costs money

Interactions that tell users what is happening

Users judge a product by how it responds: whether a button confirms the tap, a long task shows progress, a failed payment explains what to do next. Interaction design covers those moments. We design micro-interactions, transitions, gestures and every interface state, and use motion only where it helps users understand. Everything is prototyped, checked for accessibility and performance, and specified so developers can build it, as a standalone engagement or within a design and build project.

AI-assisted prototyping, designer-judged motion

How AI assists

  • Builds a state inventory for each component and screen, so no empty, loading, error or success state is missed.
  • Generates motion and interaction variations in prototypes, so timing and behavior are compared in use.
  • Drafts prototype code in CSS or Framer Motion, so interactions can be tried in a real browser early.
  • Drafts motion specs and implementation notes from approved prototypes, for designers to review.

What our experts own

  • Designers decide where motion helps and where it distracts. Every animation needs a purpose.
  • Designers judge timing, easing and feel on real devices, not only on a design canvas.
  • Designers own accessibility: reduced-motion alternatives, focus handling and no meaning shown by motion alone.
  • Designers and engineers set performance limits together and test on the devices your users have.

A form's states, from idle to recovery

Illustrative state map for a form with a submit button; each key component gets its own.

  1. Idle

    Fields show visible labels and hint text; nothing animates until the user acts.

  2. Hover and focus

    A hover cue for pointers and a visible focus ring for keyboard users, never color alone.

  3. Input and validation

    Errors appear once the user leaves a field, stating the problem in words beside it.

  4. Loading

    On submit, the button shows progress and ignores repeat presses; longer waits add a status message.

    Checkpoint: Designers judge timing on target devices

  5. Success or error

    Success confirms what changed; a failed submit explains why and keeps everything the user entered.

  6. Recovery

    Focus moves to the message, screen readers announce it, and the user can retry or edit.

    Checkpoint: Screen reader output checked by a designer

When something fails: If the connection drops mid-submit, the form keeps a local draft where agreed, says so, and resubmits only when the user chooses.

How we design interactions

  1. 01

    Audit

    We review current flows and components for missing states, unclear feedback and motion that distracts or slows users down.

  2. 02

    Design and prototype

    We define each interaction and its states, then prototype variations, with AI assistance, and try them on real devices.

  3. 03

    Specify

    Motion guidelines, tokens and implementation notes, with accessibility and performance requirements for each interaction.

  4. 04

    Build and verify

    Our engineers or yours implement the interactions; we review the build with QA on target devices, with reduced motion on and off.

What you receive

Interaction design deliverables

  • Interaction states

    Empty, loading, error, success, disabled and offline states designed for each key component and screen, including the copy users see.

  • Micro-interactions

    Feedback for buttons, toggles, form validation, saving and notifications, so users know their action worked.

  • Transitions and navigation

    Screen and page transitions that keep users oriented in multi-step flows without slowing them down.

  • Gesture design

    Swipe, drag, long-press and pull-to-refresh behavior for mobile, with visible alternatives for users who can't use gestures.

  • Motion guidelines

    Durations, easing, choreography and motion tokens documented once, so every team animates the same way.

  • Prototypes and implementation

    Interactive prototypes plus Lottie files, CSS or Framer Motion code, built by our engineers when in scope or specified for yours.

Typical interaction design requests

Typical scenarios we scope, not client case studies.

  • A Pay button with no feedback

    Customers tap Pay again because the button shows no sign it's working. We design the pressed, processing and confirmed states, block repeat taps while the request runs, and specify what users see if it times out.

  • A long import behind a spinner

    Users start a large data import, see only a spinner, then reload and start it again. We design visible progress, a way to leave and come back, and a summary of the rows that need fixing.

  • Swipe actions on a mobile list

    A mobile app wants swipe-to-archive and drag-to-reorder on its task lists. We prototype both on real phones, design an undo for accidental swipes, and keep a menu option for every gesture.

What interaction design doesn't cover

  • The visual language, such as layout grids, color and type, comes from Figma & Visual Design or your existing UI; we design how screens respond and change.
  • Some interactions need back-end support, such as progress updates for long jobs or safe retries for payments; that engineering is scoped separately.
  • A component library and tokens shared across products are Design Systems work; our motion tokens and state specs can feed into one.
  • Explainer videos, animated ads and marketing illustration aren't included; motion here serves the product's controls and flows.

How interactions connect to build, QA and operations

  • Specs developers can build from

    Prototypes show exact behavior and motion tokens define durations and easing, so engineers implement the agreed interaction, not a guess.

  • States checked by QA

    QA verifies loading, error and empty states in the build, along with keyboard use, focus order and reduced-motion behavior.

  • Designed for real failures

    Timeouts, lost connections and rejected actions are designed with engineering, so production problems reach users as clear, recoverable messages.

  • Refined after launch

    Analytics, support feedback and session reviews show where interactions confuse or slow users, and we refine them in later releases.

FAQ

Frequently asked questions

Will animations slow down our app?

Not if they're designed with performance in mind. We animate properties browsers handle efficiently, such as transform and opacity, avoid heavy effects on long lists, and test on the lower-end devices your users have. If an animation hurts responsiveness, we simplify or remove it.

Can users turn animations off?

Yes. We respect the reduced-motion setting in the user's operating system or browser, replacing movement with simple fades or instant changes, and essential information doesn't depend on animation alone.

Do you implement interactions, or only design them?

Both are possible. A standalone design engagement gives you prototypes, motion specs and implementation notes for your developers; development and hosting aren't included. If you want us to build them, our engineers implement the interactions as part of a development scope, and our designers review the result.

Which animation tools do you use?

Figma and ProtoPie for prototyping, After Effects with Lottie for complex animation, and CSS or Framer Motion in web builds. Native mobile projects use each platform's own animation tools. AI assistants help produce variations and prototype code, which designers and engineers review.
