Study Notes
Cognitive Ergonomics
Cognitive ergonomics is a multidisciplinary field that focuses on understanding how to design systems, products, and environments that are optimized for human cognitive abilities and limitations.
Human-Computer Interaction
- Human-computer interaction (HCI) is a key aspect of cognitive ergonomics, focusing on how humans interact with technology and how to design interfaces that are intuitive and easy to use.
- HCI involves understanding human cognitive processes, such as perception, attention, and memory, and designing interfaces that minimize cognitive workload and error.
- Key principles of HCI include:
- Visibility: making sure the user has all the necessary information to complete a task
- Affordance: designing interfaces that suggest their possible uses
- Feedback: providing users with feedback on their actions and the results of those actions
Cognitive Workload
- Cognitive workload refers to the mental effort required to complete a task, and is a critical concept in cognitive ergonomics.
- High cognitive workload can lead to fatigue, decreased performance, and increased error rates.
- Factors that influence cognitive workload include:
- Task complexity
- Time pressure
- Information overload
- Distractions
- Designing systems that minimize cognitive workload can improve user performance and reduce errors.
Decision Making
- Decision making is a critical aspect of cognitive ergonomics, as it involves understanding how humans process information and make choices.
- Key factors that influence decision making include:
- Information availability and quality
- Time pressure
- Cognitive biases
- Emotional state
- Designing systems that support decision making can improve user performance and reduce errors.
Error Prevention
- Error prevention is a critical aspect of cognitive ergonomics, as it involves designing systems that minimize the likelihood of human error.
- Key strategies for error prevention include:
- Designing interfaces that are easy to use and hard to misuse
- Providing feedback on user actions
- Implementing error detection and recovery systems
- Training users to identify and recover from errors
Situation Awareness
- Situation awareness refers to the ability to perceive and understand the environment and the state of the system.
- Key factors that influence situation awareness include:
- Attention and perception
- Working memory and cognitive workload
- Experience and training
- Designing systems that support situation awareness can improve user performance and reduce errors.
Overall, cognitive ergonomics is a critical field that focuses on understanding how to design systems that are optimized for human cognitive abilities and limitations. By understanding human-computer interaction, cognitive workload, decision making, error prevention, and situation awareness, designers and engineers can create systems that are safer, more efficient, and more effective.
