Usability is composed of?
- Learnability
- Efficiency
- Memorability

- 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

- Guidance
- Workload
- Explicit Control
- Adaptability
- Error Management
- Consistency
- Significance of Codes
- Compatibility
What does Satisfaction consider?
It considers users’ subjective appreciation of using the system
What does effectiveness consider?
It considers users’ ability to successfully complete a task using the system with a high degree of accuracy
What does efficiency refer to?

What is Usability?
It is the extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency, and satisfaction in a specified context of use.
What are some cognitive psychology concepts?
- Cognitive load
- Mental models
- Decision making
What are 3 sources of “guidelines” UI design relies on?
- Heuristic criteria
- Visual design principles
- Cognitive biases
What are the goals of Heuristic Evaluation?
- Provide a detailed interface analysis
- Thoroughly test the different “use cases” and “user flows”
- Avoid homogeneity problems
- Addresses basic ergonomic issues ahead of a redesign or a user test.
What are advantages of Heuristic Evaluation?
- A heuristic evaluation assures that obvious problems aren’t hiding more subtle ones
- identifies the most problematic areas to focus on during the redesign or user testing;
- It is faster and cheaper than conducting and analyzing users tests.
What is a disadvantage of Heuristic Evaluation?
The experts focus on very specific aspects and the report may lose the holistic view of the project; experts are not real users.
