Transforming Discourse Models to Structural User Interface Models

User-interface design is still a time consuming and expensive task to do, but recent advances allow generating them from interaction design models. We present a model-driven approach for generating user interfaces out of interaction design models. Our interaction design models are discourse models, more precisely models of classes of dialogues. They are based on theories of human communication and should, therefore, be more understandable to humans than programs implementing user interfaces. Our discourse models also contain enough semantics to transform them automatically into user interfaces for multiple devices and modalities. This paper presents a two-step transformation approach with an intermediate user interface model. By showing specific transformation rules, we concentrate on a major part of the first step, transforming discourse models to structural user interface models.
