    Study Notes

    Introduction to Human-Computer Interaction

    • The course SWE234: Human Computer Interaction aims to teach students about good design, involving users in the design process, building applications, evaluating interface quality, and applying learned skills in industry or continuing education.

    Goals of HCI

    • Allow users to perform tasks safely, effectively, efficiently, and enjoyably.

    Course Overview

    • The course covers the history of HCI, affordance, usability principles, human information processing limitations, user interface design, interaction design, evaluating usability, user modeling, adaptive interfaces, and 3D user interfaces.

    What is HCI?

    • HCI deals with the interaction between a person and a computer.
    • It involves both technological and human perspectives.

    Technological Perspective

    • Technical constraints and input/output devices are considered.

    Human Perspective

    • How people process information, memory, perception, motor skills, attention, language, communication, and interaction are considered.
    • Ergonomics is also a key aspect.

    Definition of HCI

    • HCI is a discipline concerned with the design, implementation, and evaluation of interactive computing systems for human use.

    History of HCI

    • Licklider outlined "man-computer symbiosis" in 1960, which aims for tightly coupled human brains and machines.
    • Goals include time sharing, electronic I/O, interactive real-time systems, and large-scale information storage.
    • Intermediate goals involve human cooperation, speech recognition, and heuristic programming.
    • Long-term visions include natural language understanding, speech recognition, and heuristic programming.

    Significant Advances

    • Time-sharing in the mid-60s made computers more accessible and led to a need for human-computer interaction.
    • Ivan Sutherland's SketchPad (1963) introduced concepts like hierarchical structures, object-oriented programming, and icons.
    • Douglas Engelbart's work focused on augmenting human intellect and improving human performance.

    Commercial Machines

    • Apple Lisa (1983) was a commercial failure, but Apple Macintosh (1984) succeeded with its aggressive pricing, non-innovative but well-done design, and excellent graphics.
