Usability

Usability is the top priority in any interface design. There are a number of requirements for a good interface. A good idea is to follow a set of heuristics and principles.

Jakob Neilsen has developed ten usability heuristics:

• Visibility of system status
• Match between system and the real world
• User control and freedom
• Consistency and standards
• Error prevention
• Recognition rather than recall
• Flexibility and efficiency of use
• Aesthetic and minimalist design
• Help users recognize, diagnose, and recover from errors
• Help and documentation
