Usability criteria: (5)
- Effectiveness: achieve specific goal accurately and completely
- Efficiency: as little work and time as possible
- Learnability: easy to learn (also for infrequent users)
- Satisfaction
- Error-tolerancy
Rules of User Centered Design (7)
- Use knowledge in the world and in the head
- Simplify the structure of tasks
- Make things visible
- Get the cognitive mapping right
- Exploit constraints
- Design for error
- Standardise
Usability engineering lifecycle
- Know the user
- Competitive (wettbewerbsfähig) analysis
- Setting usability goals
- Parallel design
- Participatory design
- Coordinated design of the total interface
- Apply guidelines and heuristic analysis
- Prototyping
- Empirical testing
- Iterative design
- Collect feedback from field use
Usability evaluation Frameworks (8)
- Formative evaluation: Iterative process throughout development
- Summative evaluation: only end product
- Quick and dirty: Fast feedback, prototyping
- Longitudinal studies: over longer time
- Case study: intensive study of a single unit à generalisation
- Remote study: experimenter and subject not at same place
- Participatory design
- Convergent method paradigm: several of these frameworks
data collection techniques (8)
- Questionnaires
- Interviewing
- Verbal protocol analysis: User verbalises thoughts during interaction
- Onscreen interaction capture
- diary keeping
- Eye tracking
- Brain activity
- Other physiological sensors
Data analysis tecniques (6)
- Content analysis (qualitative data)
- Statistical analysis
- Severity rating
- Problem frequency counting
- performance measures
- subjective measures
