Adapt-First: a MDE Transformation Approach for Supporting User Interface Adaptation

Adapting user interfaces to different contexts of use is essential to enhance usability. Adaptation enhances user satisfaction by meeting changing context of use requirements. However, given the variety of contexts of use, and the significant amount of involved information and contextual treatments, transformations of user interface models that consider adaptation become complex. This complexity becomes a challenge when trying to add new adaptation rules or modify the transformation. In this paper, we present “Adapt-first”, an adaptation approach intended to simplify adaptation within model based user interfaces. It capitalizes on differentiating adaptations and concretization via two transformation techniques: concretization and translation. First-Adapt approach aims at reducing complexity and maintenance efforts of transformations from a model to another.
