Service specification

UI/UX design

The interface is the first line of security. If a person does not understand what they are confirming, no algorithm will protect them.

§01

Process

  1. Task map
    What the user is trying to do and where they might make mistakes.
  2. Prototype
    A clickable scenario of key flows, tested with 3–5 people from the target audience.
  3. Design system
    Colour and type tokens, components with every state: loading, error, empty, locked.
  4. Handoff
    A specification with behaviour, error copy and accessibility requirements.

§02

Safe UX principles

  • Irreversible actions require explicit confirmation naming the object.
  • Permission requests appear at the moment of need, with an explanation.
  • Error messages say what happened and what to do, without system internals.
  • Sessions and devices are visible and controllable by the user.

§03

Accessibility

Text contrast ≥ 4.5:1, minimum touch target 44×44 pt, support for larger text, full keyboard and screen-reader operation, respect for the "reduce motion" setting.
