Study Notes

Human-Computer Interaction (HCI)

HCI studies the interaction between humans and computers, aiming to design systems that are user-friendly, efficient, and enjoyable.
The discipline incorporates principles from computer science, cognitive psychology, and design to enhance usability.
Essential components include understanding user perception, learning processes, and task performance.

Evolution of HCI

Early Machinery

Initial machinery prioritized functionality over usability, requiring extensive training for specialists to operate.
The industrial revolution set the stage for more complex machines, without a focus on user-centered design.

1970s-1980s: Personal Computers

The introduction of personal computers shifted design focus towards usability for general consumers, not just trained specialists.

1980s-1990s: Graphical User Interface (GUI)

Xerox Star (1981) was the pioneering system supporting a graphical user interface (GUI) with WIMP (windows, icons, menus, pointer).
The GUI utilized visual metaphors to make technology more intuitive for users.

1990s-Present: The World Wide Web

The emergence of the internet revolutionized user interaction, becoming a key platform for information exchange and e-commerce.
Web design faced new challenges such as compatibility across different browsers and screen sizes, driving research into web usability.

Present and Future Technologies

Ubiquitous Computing: Seamless integration of computing into everyday objects necessitates intuitive interfaces.
Augmented and Virtual Reality (AR/VR): Offers immersive interactions but requires careful design of user navigation systems.
Artificial Intelligence (AI): Personalizes user experiences by adapting to individual behavior and preferences.
Voice and Gesture Interfaces: Demand intuitive design for natural and accurate interactions.
Brain-Computer Interfaces (BCIs): Enable direct communication between brain and system, presenting unique design challenges.

Importance of Usability Design

Usability ensures systems are intuitive, efficient, and satisfying, enhancing user experiences.
Key principles include consumer cognitive psychology, consistency, visibility, affordances, error prevention, and efficiency.

Core Usability Principles

Cognitive Psychology: Recognizes limits in perception, memory, and attention; designs should minimize cognitive load for users.
Consistency and Standards: Both internal and external consistency help users learn and predict system interactions.
Visibility and Feedback: Important functions should be easily noticeable; immediate feedback is necessary for user reassurance.
Affordances and Metaphors: Objects should visually suggest their use; familiar metaphors ease understanding.
Error Prevention and Recovery: Designs should minimize user errors and provide clear recovery options when mistakes occur.
Efficiency and Satisfaction: Well-designed systems enable quick achievement of user goals and enhance satisfaction.

Disciplines Contributing to HCI

Computer Science: Provides the technical foundation for software and hardware design, particularly in algorithms, programming, and interface creation.
Psychology: Offers insights into user behavior and cognition, essential for creating user-friendly interfaces.
Design: Focuses on the aesthetic and functional aspects to create intuitive user experiences.
Ergonomics and Human Factors: Ensures designs fit users' physical and psychological needs to minimize errors and strain.
Sociology and Anthropology: Understands the social contexts and cultural factors affecting technology use, fostering inclusive designs.
Linguistics: Informs the development of language-based interfaces, enhancing interactions through natural language processing.
Cognitive Science: Studies thought processes, aiding designers in creating intuitive systems aligned with user cognition.
Artificial Intelligence (AI): Facilitates the development of intelligent systems that improve user interactions.
Communication Studies: Explores effective information conveyance, aiding in designing clear and communicative interfaces.
Engineering: Provides the technical skills necessary for practical implementation of user-friendly systems.
Ethics and Philosophy: Addresses the moral implications of technology design and use, ensuring respect for user rights and privacy.
Education: Focuses on designing technology that supports educational needs, enhancing learning and skill acquisition.
