User interface modeling is a development technique used by computer application programmers. Today's user interfaces (UIs) are complex software components, which play an essential role in the usability of an application. The development of UIs requires therefore, not only guidelines and best practice reports, but also a development process including the elaboration of visual models and a standardized notation for this visualization.
The term user interface modeling is mostly used in an information technology context. A user interface model is a representation of how the end user(s) interact with a computer program or another device and also how the system responds. The modeling task is then to show all the "directly experienced aspects of a thing or device" .
Modeling user interfaces is a well-established discipline in its own right. For example, modeling techniques can describe interaction objects, tasks, and lower-level dialogs in user interfaces. Using models as part of user interface development can help capture user requirements, avoid premature commitment to specific layouts and widgets, and make the relationships between an interface’s different parts and their roles explicit. .

Famous quotes containing the words user and/or modeling:
“A worker may be the hammer’s master, but the hammer still prevails. A tool knows exactly how it is meant to be handled, while the user of the tool can only have an approximate idea.”
—Milan Kundera (b. 1929)
“The computer takes up where psychoanalysis left off. It takes the ideas of a decentered self and makes it more concrete by modeling mind as a multiprocessing machine.”
—Sherry Turkle (b. 1948)
