- Prototyping may be low fidelity (such as paper-based) or high fidelity (such as software-based)
- High-fidelity prototypes may be vertical or horizontal.
- Low-fidelity prototypes are quick and easy to produce and modify and are used in the early stages. There are two aspects to the design activity: conceptual design and physical design.
- Conceptual design develops a model of what the product will do and how it will behave, while physical design specifies the details of the design such as screen layout and menu structure.
- We have explored three perspectives to help you develop conceptual models: an interaction paradigm point of view, an interaction mode point of view, and a metaphor point of view.
- Scenarios and prototypes can be used effectively in conceptual design to explore ideas.
- We have discussed four areas of physical design: menu design, icon design, screen design and information display.
- There is a wide variety of support tools available to interaction designers.
