Model-based design of multi-device interactive applications based on web services

Creating an interactive application based on pre-existing functionalities poses a number of novel issues in the design process. We discuss a method and an associated model-based language, which aim to address such issues in multi-device contexts. One specific aspect of this method is the ability to obtain user interfaces for accessing multiple services. In addition, the possibility to specify interactive objects, Web services accesses and scripts allows designers to describe Rich Internet Applications as well.
