Week 12 Flashcards
What is the definition of Human Factors?
The study of how humans interact with systems, products, and environments to optimize safety, efficiency, and usability.
What is the objective of studying Human Factors?
Enhance system design by considering human limitations and capabilities.
List the key disciplines involved in Human Factors.
- Psychology
- Engineering
- Design
- Physiology
What is Ergonomics?
Focuses on designing systems to fit human needs and abilities.
What are the three types of Ergonomics?
- Physical ergonomics
- Cognitive ergonomics
- Organizational ergonomics
What does physical ergonomics focus on?
Focuses on how people physically interact with their environment. Like how your body moves, sits, or lifts things. To make tasks safer, more comfortable, and efficient.
What does cognitive ergonomics relate to?
How people think and process information when interacting with systems. It focuses on things like memory, attention, decision-making, and how well instructions or technology match the way our brains work.
What is the focus of organizational ergonomics?
Focuses on optimizing socio-technical systems, policies, and work environments.
What are the three usability principles?
- Effectiveness
- Efficiency
- Satisfaction
What is the Information Processing Model?
Describes the stages of perception, cognition, and action.
What is perception in the context of Human Factors?
How users sense information.
What does cognition refer to?
Processing and interpreting information.
What is the significance of mental workload?
Excessive cognitive demand can reduce efficiency and increase errors.
How should interfaces be designed concerning cognitive load?
To reduce unnecessary cognitive load.
What is selective attention?
Ability to focus on relevant information.
What is divided attention?
Managing multiple tasks at once.
What are the limitations of working memory?
Avoid overwhelming users with too much information at once.
List the types of human errors.
- Slips
- Lapses
- Mistakes
What are slips in the context of human error?
Execution errors, e.g., pressing the wrong button by mistake.
What are lapses in human error?
Forgetting to perform a step in a process.
What are mistakes in human error?
Incorrect decision due to misunderstanding or lack of knowledge.
What is redundancy in system design?
Backup systems to prevent failures.
What does error tolerance mean in design?
Allow users to recover from mistakes.
What is the purpose of feedback mechanisms?
Clear feedback to indicate errors and guide corrections.
