Model Types
The different aspects of a user interface requires different model types. Some of the models that may be considered for UI-modeling are:
- Domain model, including data model (defines the objects that a user can view, access and manipulate through the user interface)
- Navigation model, defines how the objects that a user view could be navigated through the user interface
- Task model. (describes the tasks an end user performs and dictates what interaction capabilities must be designed)
- User model (represents the different characteristics of end users and the roles they are playing within the organization)
- Platform model (used to model the physical devices that are intended to host the application and how they interact with each other)
- Dialogue model (how users can interact with the objects presentation (as push buttons, commands, etc.), with interaction media (as voice input, touch screen, etc.) and the reactions that the user interface communicates via these objects)
- Presentation model (application appearance, representation of the visual, haptic and auditory elements that the user interface offers to its users)
- Application model (commands and data the application provides)
UML can be used for several of the models mentioned above with varying degree of success, but it lacks support for user modeling, platform modeling and presentation model.

Famous quotes containing the words model and/or types:
“There are very many characteristics which go into making a model civil servant. Prominent among them are probity, industry, good sense, good habits, good temper, patience, order, courtesy, tact, self-reliance, many deference to superior officers, and many consideration for inferiors.”
—Chester A. Arthur (1829–1886)
“As for types like my own, obscurely motivated by the conviction that our existence was worthless if we didn’t make a turning point of it, we were assigned to the humanities, to poetry, philosophy, painting—the nursery games of humankind, which had to be left behind when the age of science began. The humanities would be called upon to choose a wallpaper for the crypt, as the end drew near.”
—Saul Bellow (b. 1915)
