Sedge / Services / Interface design

Interfaces drawn to the last state

We design user experience and visual interfaces with the rigour of a technical drawing: every component, state and transition specified.

Research proportionate to risk

Not every project needs weeks of research. We size it to the risk: a short round of interviews for a new audience, a task-based test of an existing journey, or simply a careful review of support emails and analytics you already have.

From flow to specification

Flows map the paths users take, including the unhappy ones. Wireframes settle structure. Prototypes let people try it. Then the specification records exact behaviour: what happens on tap, what the error says, where focus goes, what a screen reader announces.

State inventory example

Default

Field empty, label visible, hint text below.

Focus

2px outline, contrast at least 3:1 against background.

Error

Message names the problem and the fix, announced politely.

Disabled

Avoided where possible; reason shown if used.

Loading

Skeleton after 300 ms, never a blank screen.

Success

Confirmation stays until dismissed or replaced.
