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.

- Shopping cart
- Proceeding to check-out
- 1-click
- Gift wrapping
- Cash register
