Chapter 1 Flashcards
Why are HCI designers important and how have they transformed technology?
- Helped make computers more social, by enabling users to communicate and collaborate effectively.
- Made applications simpler and more usable for the diverse usability by everyone.
- Enabled applications to be used on a diverse number of devices, like phones and many others.
Define Ergonomics in relation to HCI:
The arrangement of displays and controls, control design, fatigue and health issues, and design for the disabled.
HCI science combines knowledge from:
- Psychologists
- Computer Scientists
- Graphic Designers
- Human Factors and Ergonomics Experts
- Sociologists
Definition of HCI:
It’s the science of the design and evaluation of interactive technology.
1 - HCI is important because:
2 - Define usability:
1 - it can increase productivity, efficiency, and safety of the users.
2 - Usability: How easy it is for users to use the interface.
Define “Effective” & “Efficient”:
Effective: doing the right things.
Efficient: doing things right.
Usability requires close attention to the “requirement analysis” and testing.
What are the goals in requirement analysis:
- know the users needs.
- Ensure reliability
- consistency
- be on time and on budget.
how to measure an effective interface:
- Time to learn
- Speed of performance
- Rate of errors by users.
- Retention.
- User feedback.
Life-critical systems (air traffic, medicine, military, etc) require focus on (Blank1) with less importance on (Blank2).
Blank1: reliability and effectiveness at all times.
Blank2: time to learn, cost, and retention.
Aspects of universal usability:
- Personality
- Physical ability
- Cognitive ability
- Culture and nationality
- Age
(T/F) early planning is more cost-efficient than adding on later.
True
Industrial and commercial systems (banking, reservations, etc) require more focus on (Blank)
ease of learning, cost, and speed.
