Consider following when designing user interface:
- Do not get lost
- Help facility to guide
- Look and Feel
- Colours to suit brief and create right mood
- Visually appealing
- Meet expectations
More specific users are, easier to target material and delivery.
- Define users
- What do they want?
- How can it be delivered?
Example – Amazon. Does number of things well:
- Navigation – no broken links, good search facility
- Trusted brand – buying and delivery
- Search can be ordered in different ways
- Users able to rate & comment on merchandise
