Study Notes
Usability: Measurement
- Usability is measured to ensure systems are user-friendly
- Key principles for designing user-friendly interfaces were developed by Jakob Nielsen
- Nielsen's 10 Usability Heuristics are used to evaluate interface design
- 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
Visibility of System Status
- Systems should provide consistent feedback on actions
- Users should be informed about the current status of the system
Match Between System and the Real World
- Systems should use real-world terms, conventions, and logical order
- Information should be presented in a natural way
User Control and Freedom
- Systems should allow users to easily undo errors or navigate away from unwanted states
Consistency and Standards
- Systems should have consistent terminology, actions, and interactions
- Follow platform conventions
Error Prevention
- Design systems to prevent errors from occurring
- Provide clear error messages and helpful suggestions
Recognition Rather Than Recall
- The system should use recognizable components
- Users should not have to remember information between interactions
Flexibility and Efficiency of Use
- Systems should offer shortcuts and other efficient ways to complete tasks
Aesthetic and Minimalist Design
- Keep dialogue free from unnecessary information or cluttered elements
Help Users Recognize, Diagnose and Recover from Errors
- Error messages should be in plain language, informative and constructive
Help and Documentation
- Help and documentation are important parts of every system
- Documentation should be searchable and focused on tasks
- Be concise and provide concrete steps in a manageable way
Interface Metaphor Design (User's Familiar Knowledge)
- Interface metaphors use familiar examples to ease the learning process
- Metaphors use user's prior knowledge about similar concepts from other domains
- Examples include desktop metaphor, web portals
Benefits of Interface Metaphors
- Ease of learning new systems
- Helps understand underlying conceptual models
- Makes interface accessible for a wider range of users
Problems with Interface Metaphors
- Conflicting with design principles
- Limits conceptual models to what already exists
Evaluate Metaphors
- Does the metaphor make sense to users?
- Does it make the system simpler and easier to use?
- Assess whether it is relevant and if it's easy to represent
- Consider how well users understand the metaphor
Case Study: Usability of University Web Sites
- This case study focuses on the usability of a university-wide student information system
- The study explores how well the system meets the requirements of various groups of users, including Nielsen's usability principles.
