    Study Notes

    Historical Roots of HCI

    • Achieving usability involves understanding user abilities and limitations, specific user needs, work environments, tasks, and technology limits.
    • Key reasons for project failure include lack of senior management commitment, user involvement, clear requirements specifications, and poor project planning.

    User-Centered Approach

    • Focuses on users' needs during the software development process.
    • Key activities include involving users, obtaining regular feedback, and providing prototypes for evaluation and improvement.

    Stages of Skill Development

    • Intermediate Stage: Users develop methods for tasks; improvement noted through practice.
    • Expert Stage: Skills become automatic, allowing for quick and efficient task performance.

    Errors and Mental Models

    • Two types of errors:
      • Slips: Accidental mistakes caused by distraction or routine changes.
      • Mistakes: Incorrect actions based on faulty knowledge or understanding.
    • Mental models shape our understanding of systems; incorrect models can lead to unexpected outcomes.

    Theories of Emotion

    • James-Lange Theory: Emotions arise from physiological changes.
    • Cannon-Bard Theory: Emotions and physical changes occur simultaneously.
    • Schachter-Singer Theory: Emotions depend on situational interpretation of physiological responses.

    Future of Computing

    • Advanced visual technologies will enhance the quality of pictures and videos.
    • Conversational computers will comprehend and respond verbally.
    • Increased computer speed will enable quicker task completion.
    • Devices will feature both large screens for groups and portable small screens.
    • Integration of computers into everyday items will facilitate communication among devices.
    • Computers will enhance group collaboration and access to extensive information.

    Interaction Design

    • Understanding human interaction requires knowledge of perception, motor skills, and cognitive processes as outlined by the Model Human Processor.
    • The model includes:
      • Perceptual System: Relates to seeing and hearing.
      • Motor System: Involves physical manipulation of objects.
      • Cognitive System: Focuses on thinking and problem-solving.
    • Considerations for interaction include information input/output, memory storage, processing of information, emotional influences, and individual differences.
