Users Interfaces Adaptation for Visually Impaired Users Based on Meta-Model Transformation
Lamia Zouhaier, Yousra Bendaly Hlaoui, Leila Jemni Ben Ayed · 2017
We apply the Model-Driven Engineering for adapting User Interfaces (UI) in order to improve their accessibility into interactive system (IS). The solution that we propose has to be generic to be applicable in any context and with any type of UI. Therefore, we have developed a model driven approach based on meta-model transformations. This approach generates modality-based UI models adapted to each kind of disability. Hence, we have developed an accessibility context described with the type of disability, the used platform, the user identity, his/her situation and the surrounded environment. This context is defined with an ontology which will be used in the adaptation process. To generate Platform Independent and Specific UI Models, we have proposed a set of metamodel transformation rules.
