What is usability?
The effectiveness, efficiency, and satisfaction with which specified users achieve goals in specific environments (ISO 9241-11).
What is engineering?
Applying science and math to solve problems and create solutions.
Define usability engineering.
A systematic, iterative process involving user needs, prototype design, testing, and refinement to optimize user experience.
What does usability engineering not involve?
It does not involve building systems; it focuses on evaluation and problem-solving.
What is Interaction Design (IxD)?
The design of interactive products and services focused on how users interact with them.
What are some alternative terms for Interaction Design?
User interface design, UX design, product design, software design, user-centered design.
What is usability/human factors engineering?
Designing systems based on human behavior, abilities, and limitations to ensure adequate usability.
What is a use error?
An act or omission that produces an unintended result compared to what was expected or intended.
What makes a design ‘good’ in usability terms?
It is effective, easy to learn, and enjoyable to use.
Why is usability important for websites or devices?
Poor usability drives users away; if it’s hard to navigate, read, or understand, users leave.
What is the usability improvement process?
Understand users → Create prototype → Form hypothesis → Test it → Observe → Refine.
When should usability testing be done?
Before designing, during competitor analysis, with prototypes, and before implementation.
What are key usability metrics?
Error frequency and recovery, efficiency, learnability, memorability, and user satisfaction.
What does user experience (UX) emphasize?
A deep understanding of user needs, values, abilities, and limitations.
What is accessibility in UX?
Designing for people with disabilities using tools like screen readers or voiceover features.
What is inclusiveness in UX?
Designing fairly for all people regardless of age, disability, or socioeconomic background.
What is Human-Computer Interaction (HCI)?
The design, evaluation, and implementation of interactive systems for human use.
What is HCI not?
Cosmetics, last-minute fixes, or just interface programming.
How do you know if an object is well-designed?
It’s intuitive, easy to use, and offers clear clues to its operation.
What are the key concerns of usability engineering?
The context of use, user characteristics, and how users interact with systems.
