Model driven design of ubiquitous interactive applications

Abstract

The ubiquitous availability of interactive applications means that the diversity of people use an increasing number of different mobile or networked computing devices with diverse but constrained input and output capabilities. This increases the interest in programs and technologies that exploit context knowledge, such as the user's location or past behavior. At the same time, the behavior of the application should be predictable and correspond to the user's expectations. In this document, we propose the usage and generation of high-level models incorporating context information for certain aspects of the design while still allowing some designer freedom in other areas. The usage of models, with roots in both human-computer interaction and software engineering, should however not divert attention away from the final users, which should be involved in the design process and provide feedback on prototypes that are generated from the specified models.
