Study Notes
Universal Design
- Designing systems accessible to all users regardless of disability, age, or cultural background
- Benefits everyone, including those with disabilities, those working in noisy environments, and those with limited access to technology
- Designing for accessibility can improve websites for mobile users and older browsers
- Importance of universal design is increasingly being recognized by law
Designing Usable Systems
- Legal requirements for employers to provide usable computer systems
- Focus on user experience for safety and productivity
- EC Directive 90/270/EEC requires employers to ensure software suitability, ease of use, adaptability, feedback, and ergonomic principles
Human Computer Interaction (HCI)
- Developed in the early 1980s, with roots in earlier fields like ergonomics and human factors.
- Systematic study of human performance was started at the beginning of the 20th century.
- World War II sparked the study of human-machine interaction.
- Ergonomics focuses on physical characteristics of machines and their impact on performance.
- Human Factors is similar, including cognitive issues.
