    Study Notes

    Human-Computer Interaction (HCI) Challenge

    • HCI involves understanding users, their tasks, and their surrounding environment
    • Involves gathering and analyzing user interface (GUI) requirements
    • Includes designing, prototyping, and evaluating systems

    The Goals of HCI

    • Focus on developing or improving system safety, utility, effectiveness, efficiency, and usability
    • Systems include computers
    • Goal is to improve interactions with systems using computers

    Usability

    • A usable system is easy to learn, easy to use, efficient, effective, safe, and enjoyable to use

    Bad User Interfaces

    • Can be annoying, embarrassing, frustrating, or even deadly
    • Increase mistakes in data entry and system operations
    • Can make system functions inaccessible
    • Can lead to system failure due to user rejection

    Importance of HCI in the Context of the World Wide Web (WWW)

    • Good user interfaces are not easy to create because of basic misconceptions
    • Common misconceptions are that if developers or non-technical staff can use a system, everyone can
    • People mistakenly believe that good user interfaces are based on common sense
    • Another common misconception is that a usable system is achieved simply by following style guidelines
