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.
