    Study Notes

    Cognitive Ergonomics

    • Cognitive ergonomics explores how mental processes (perception, memory, decision-making) affect human-system interactions, aiming to enhance performance, safety, and user satisfaction.

    Importance of Cognitive Ergonomics

    • Key to designing systems that match human abilities, reducing errors and stress.
    • Emerged post-World War II to address challenges in handling complex machinery.

    Course Structure

    • Topics include human cognitive abilities, human-computer interaction, and physical stress on cognitive demands.

    Impact of Stress

    • Physical stress can lead to increased errors and compromised safety.
    • Examples: handling machinery during World War II, pilots' challenges due to design flaws in cockpit displays.

    Redesigning for Safety

    • Redesigning displays reduced accident rates significantly.

    Cognitive Skills

    • Involve recognition, recall, reasoning, problem-solving, and decision-making at various levels.
    • Examples: recognizing traffic signals, understanding signs, problem-solving while crossing roads, and decision-making.

    Complexity of Cognition

    • Understanding cognitive layers is crucial to enhance efficiency, performance, and safety in tasks.
    • Cognition is complex, and individuals vary in their ability to comprehend it.

    Cognitive Science

    • Multidisciplinary field involving philosophy, language, anthropology, neuroscience, artificial intelligence, and psychology.
    • Aims to understand human cognition and decision-making processes.

    Cognitive Ergonomics' Focus

    • Studies mental processes affecting human-system interaction, enhancing performance, safety, and user satisfaction in system design.
    • Focuses on mental processes, work laws, and understanding human cognition.

    Inclusive Design

    • Designs systems based on user types, gender, and age to support their needs for enhanced performance and efficiency.
    • Addresses challenges faced by users, especially the elderly, in handling advanced technology like mobile banking.

    Importance of Cognitive Ergonomics

    • Enhances user experience, reduces negative situations, and improves system handling.
    • Addresses challenges in human cognition, problem definition, and provides solutions.

    Benefits of Cognitive Ergonomics

    • Helps users perform better under stress, enhances safety, and improves satisfaction, catering to different user types and tasks like driving or crossing roads.
