A GUI modeling language for mobile applications

The market of mobile applications is constantly changing and growing, partly due to the popularity of software that supports daily tasks and the emergence of new communication medias. Applications of this kind are typically small but require high usability interfaces, which are often based on small's sets of patterns with proven efficacy. Using patterns is one of the main principles of model-driven development, a paradigm with the potential to reduce development time and coding errors. However, there exist many challenges for improving the usability of automatically generated mobile interfaces. To face some of these challenges, this paper proposes a method to model mobile interfaces, which is part of an ongoing research project aimed at model-driven development of fully-functional mobile applications. We present the modeling constructs, which are inspired by recent studies on best practices, and evaluate the feasibility of the application of the proposal to an archetypical case.
