Design Disciplines #

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 advice 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.
