Study Notes
User Interface Evaluation
- Human-centered design (user-centered design) focuses on the needs of users, creating solutions that fit their needs.
- Evaluation is the final stage of software development, refining the product based on previous results.
- Usability is how easily and quickly a user can use a UI (user interface).
- Measured quantitatively by task completion time, accuracy, and error rate.
- Measured qualitatively by user surveys regarding ease of use, learning, and preference.
- User Experience (UX) encompasses user interactions with the entire product; feelings, satisfaction, and perception. High UX generally equates to high usability.
Evaluation Methods
- Timing matters in user interface evaluation and can be between stages of development or after.
- Different types of evaluators exist (experts vs. end-users).
- Evaluation methods include:
- Focus Interviews: Simple question-and-answer sessions with users.
- Can focus on specific user groups and features.
- Cognitive Walkthroughs: Interviews using a step-by-step process to assess if the user interface helps users, with a group or individual evaluators, can be done early in design.
- Expert Heuristic Evaluation: HCI experts use guidelines to evaluate the UI.
- Efficient and cost-effective method by gauging interface by system status, display, layout and design etc.
- This method is similar to focus interview and observation study.
- Focus Interviews: Simple question-and-answer sessions with users.
- Measurement involves using numerical scores from user testing or surveys to evaluate effectiveness of the user interface.
- Using a compact, understandable survey design.
- Limit questions.
- Use an odd-numbered scale, e.g., 5 or 7.
- Categorize the questions.
