The Complicity of Model-Based Approaches and Patterns for UI Engineering

Abstract: Starting from some general considerations, we will outline different kinds of patterns that can impact the creation of the task model. We will then introduce a 4-part “strategy ” about the process of pattern application followed by an analysis about what a formal notation for patterns for the task model should encapsulate. In particular, we discuss the fundamental concepts underlying a generic notation for patterns. By using task patterns, different views of patterns are suggested using UML and Concurrent Task Tree notations. A first classification of patterns according to models is also drawn. Finally, we will introduce a tool that acts as a wizard and guides pattern users throughout the process of pattern application
