Patterns in Task-Based Modeling of User Interfaces

The development of user interfaces is influenced by various challenges in recent years. These are foremost caused by increasing complexity of the underlying applications and the use of these applications on different devices, by different user types and in changing environments. Model-based user interface development approaches have been shown to be suitable to face these challenges. However, creating, transforming and linking the various included models are complex tasks. Employing patterns can avoid these disadvantages and provide an advanced concept of reuse. In this paper a general framework is introduced that describes how model-based approaches can be extended with patterns. The implementation of the framework is exemplarily shown in order to derive a concrete pattern-driven model-based approach for user interface development. A case study is used to illustrate the derived approach.
