    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.
