Human Centred Design
Here are four key aspects to keep in mind when designing User Experiences.
- Visual
- Intellectual
- Memory
- Motor
Visual
Optimise visual comprehension by:
- Matching screen flow to task flow.
- Using good grouping and labelling.
- Including no gratuitous colour.
Intellect
Simplify decision making by:
- Providing previews and easy escapes.
- Using controls consistently.
- Providing good system feedback.
Memory
Minimise the memory load by:
- Making options visible.
- Designing for recognition versus recall.
- Providing defaults.
Motor
Minimise movement time and interactions by:
- Using short distances and large targets.
- Optimising for the input device.
- Using natural response mappings.
- Reducing windows and steps.
- Follow user expectation for layout.
- Avoid three or more nouns in a row.
- When typing, using the same finger twice slows people down.
