The understanding of how users receive, process and store information.
Information can be received by 4 main ways:
- Vision (seeing)
- Distinguishing colours can effect how a person reacts to a situation (Red means Warning or Danger). This shouldn't be relied on because of colour blindness.
- Most commonly sounds are used in warning messages - the Dong in Windows. This is standard and therefore the user knows straight away that it is a warning.
- Human nature wants something to ensure a button has been pressed - buttons allow that pressure to be enforced.
- The movement of small objects is understandably difficult.
