UI & Interaction Design
helio / ui-interaction-designNo dedicated designer on the team yet. Your AI teammate turns a feature brief into information architecture, a prototype, and interaction notes — states and edge cases spelled out.
What is UI & Interaction Design?
- ·Turns a paragraph into a reviewable prototype: Information architecture first, then a low-fidelity structure pass, then high fidelity once the flow is confirmed.
- ·Documents every interaction, not just the happy path: Click/tap behavior, loading and error states, and edge cases — spelled out screen by screen.
- ·Hands off without a design meeting: Prototype plus annotations, ready for engineering to implement directly.
- ·Works within your existing design system: Proposes one from your reference styles if you don't have one yet, then applies it consistently.
What does UI & Interaction Design produce?
| 🗺️Information architecture | Screen and flow structure, produced before any visual design starts. |
| 🖼️Low-fidelity prototype | For structure review, before pixels get polished. |
| ✨High-fidelity prototype | Polished version, once the structure is confirmed. |
| 📝Interaction annotations | Click/tap behavior and state transitions documented per element. |
| ⚠️Edge-case spec | Empty, loading, error, and permission-denied states called out explicitly. |
The SOP, step by step.
- 01
Take the brief
Feature description, target users, reference style if one exists.
- 02
Produce information architecture
The structure of screens and flows, before any visual design.
- 03
Build a low-fidelity prototype
For structure review — confirm the flow before polishing pixels.
- 04
Raise to high fidelity
Once structure is confirmed, produce the polished version.
- 05
Walk the confirmed prototype
Screen by screen, element by element.
- 06
Document each interaction
What happens on click, hover, and every state transition.
- 07
Specify edge states
Empty, loading, error, and permission-denied — not left to be discovered during build.
- 08
Hand off to engineering
Prototype plus annotations, ready to implement without a design meeting.

Questions
- Does it design in Figma directly?
- Where Figma access is connected, yes — it can work within your existing component library rather than producing a disconnected mockup.
- What if I don't have a design system yet?
- It can propose one from the reference styles you give it, then apply it consistently across every screen it designs afterward.
- Does it replace a designer?
- It's built for teams without a dedicated designer yet, or that need a fast first pass. A human still reviews structure and taste before anything ships.
- Can it review an existing design against usability issues?
- Yes — at any milestone, it can run a design against a usability checklist and flag gaps: missing states, unclear hierarchy, inconsistent spacing.
