    Study Notes

    Interaction Types and Interface Styles

    • Direct manipulation is suitable for tasks that involve designing, drawing, flying, driving, or sizing windows.
    • Issuing instructions is suitable for repetitive tasks, such as spell-checking and file management.
    • Conversing is suitable for finding out information, requesting music/TV, or learning.
    • Hybrid conceptual models support multiple ways of carrying out the same actions.

    Interaction Types and Interface Styles (continued)

    • Interaction types describe what a person is doing when interacting with a system, such as instructing, talking, browsing, or responding.
    • Interface styles refer to the kind of interface used to support the interaction, such as command, menu-based, gesture, or voice.

    Interface Styles

    • Many interface styles are available, including:
      • Command
      • Speech
      • Data-entry
      • Form fill-in
      • Query
      • Graphical
      • Web
      • Pen
      • Augmented reality
      • Gesture

    Conceptual Knowledge

    • Paradigms inspire conceptual models and guide research, involving shared assumptions, concepts, values, and practices.
    • Examples of paradigms in HCI include:
      • Ubiquitous computing
      • Pervasive computing
      • Wearable computing
      • Internet of Things (IoT)
      • Human-Centered Artificial Intelligence

    Challenges and Conceptualizing Design

    • Challenges in conceptualizing design include scrutinizing vague ideas and assumptions about benefits, feasibility, and desirability.
    • Conceptualizing design involves considering many unknowns in the initial stages of a design project, especially for new products.
    • Examples of design concepts include a mobile robot server and an automated robot server.

    Conceptual Models

    • Conceptual models describe the underlying concepts and principles of a system.
    • Good conceptual models are simple and intuitive to use.
    • Interface metaphors can be based on activity, object, or a combination of both, and can be innovative and accessible.

    Interface Metaphors

    • Interface metaphors are designs that resemble physical entities and have their own properties.
    • Examples of interface metaphors include the desktop metaphor, web portals, and search engines.
    • Benefits of interface metaphors include easier learning, intuitive understanding, and innovation.
    • However, interface metaphors can also have limitations, such as constraining designers, conflicting with design principles, and not scaling well.

    Activity

    • Describe the components of the conceptual model underlying online shopping websites, including:
      • Shopping cart
      • Proceeding to check-out
      • 1-click
      • Gift wrapping
      • Cash register
