## Consistency

- **Consistent with real life:** in line with the process and logic of real life,
  and comply with languages and habits that the users are used to.

- **Consistent within interface:** all elements should be consistent, such as:
  design style, icons and texts, position of elements, etc.

## Feedback

- **Operation feedback:** enable the users to clearly perceive their operations
  by style updates and interactive effects.

- **Visual feedback:** reflect current state by updating or
  rearranging elements of the page.

## Efficiency

- **Simplify the process:** keep operating process simple and intuitive.

- **Definite and clear:** enunciate your intentions clearly so
  that the users can quickly understand and make decisions.

- **Easy to identify:** the interface should be straightforward,
  which helps the users to identify and frees them from memorizing and recalling.

## Controllability

- **Decision making:** giving advices about operations is acceptable, but do not
  make decisions for the users.

- **Controlled consequences:** users should be granted the freedom to operate,
  including canceling, aborting or terminating current operation.
