PIM Tool: Support for Pattern-Driven and Model-Based UI Development

Abstract. Model-based approaches describe the process of creating UI models and transforming them to build a concrete UI. Developers specify interactive systems on a more abstract and conceptual level instead of dealing with low level implementation. However, specifying the various models is a complex and time consuming task. Pattern-based approaches encapsulate frequently used solutions in form of building blocks that developers may combine to create a user interface model. Thus they enforce reuse and readability and reduce complexity. In this paper we present a comprehensive framework that unites model-based and pattern-driven approaches. We introduce the “Patterns In Modelling ” (PIM) tool, that implements this framework. We will demonstrate the functioning of the tool by using an illustrative example. We primarily focus on the creation of the task model and give a brief outlook how patterns will be applied to the other levels within the framework.
