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.
