These are ten general principles for user interface design. They are called "heuristics" because they are more in the nature of rules of thumb than specific usability guidelines.

Visibility of system status 系统状态可视

The system should always keep users informed about what is going on, through appropriate feedback within reasonable time.

 

Match between system and the real world 系统和实际生活经验相符

The system should speak the users’ language, with words, phrases and concepts familiar to the user, rather than system-oriented terms. Follow real-world conventions, making information appear in a natural and logical order.

 

User control and freedom 用户控制和有自由度

Users often choose system functions by mistake and will need a clearly marked "emergency exit" to leave the unwanted state without having to go through an extended dialogue. Support undo and redo.

Consistency and standards 连贯和标准

Users should not have to wonder whether different words, situations, or actions mean the same thing. Follow platform conventions.

 

Error prevention 防止错误

Even better than good error messages is a careful design which prevents a problem from occurring in the first place. Either eliminate error-prone conditions or check for them and present users with a confirmation option before they commit to the action.

 

Recognition rather than recall 直接认知而不是回忆

Minimize the user’s memory load by making objects, actions, and options visible. The user should not have to remember information from one part of the dialogue to another. Instructions for use of the system should be visible or easily retrievable whenever appropriate.

 

Flexibility and efficiency of use 有效率、有弹性的使用

Accelerators — unseen by the novice user — may often speed up the interaction for the expert user such that the system can cater to both inexperienced and experienced users. Allow users to tailor frequent actions.

 

Aesthetic and minimalist design 人文因素和极小化设计

Dialogues should not contain information which is irrelevant or rarely needed. Every extra unit of information in a dialogue competes with the relevant units of information and diminishes their relative visibility.

 

Help users recognize, diagnose, and recover from errors 帮助用户认知、诊断错误并从错误中恢复

Error messages should be expressed in plain language (no codes), precisely indicate the problem, and constructively suggest a solution.

 

Help and documentation 帮助和文档

Even though it is better if the system can be used without documentation, it may be necessary to provide help and documentation. Any such information should be easy to search, focused on the user’s task, list concrete steps to be carried out, and not be too large.
