Chapter 44. Abstract Objects > Pitiful Prototype

Pitiful Prototype

Some people refer to such sheets of papers with colored slips on them as “low-fidelity prototypes,” but thinking of them as prototypes misses the point. They are not poor prototypes or inexact interfaces; they are good abstract models of user interfaces. They make it easy to try out alternative ways to break down tasks or group features, to experiment with different architectures for the user interface.

To complete a picture of the user interface architecture, we also need an overview that represents all the interaction contexts and how the work of users might take them from context to context, something analogous to a state-transition diagram or an object communication diagram. A context navigation map is a model that represents each interaction context by a named symbol and shows the possible transitions among them with connecting arrows. The navigation map is another level of abstraction removed from the content model because it hides information, ignoring the contents of interaction contexts, that is, the tools and materials they contain.
