Simple Heuristic Evaluation
Is interface simple?
- Does it reflect users current work process?
- Does it guide the user through the task sequence?
Are the meanings of graphical elements clear?
How well is the interface organized?
- Do navigational aids support organization
- Is user feedback adequate?
What unnecessary information does the user encounter?
- What information is missing?
More Elaborate Heuristic Evaluation
Visibility of system status
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
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
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
Users should not have to wonder whether different words, situations,
or actions mean the same thing. Follow platform conventions.
Even better than good error messages is a careful design which prevents
a problem from occurring in the first place.
Recognition rather than recall
Make 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
Flexibility and efficiency of use
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
Aesthetic and minimalist design
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.
