Abstract. With the advent of new media and the delivery of recent means of communication, associated with the progress of networks, the circumstances of software use, as well as the skills and the preferences of the users who exploit them, are constantly varying. The adaptation of the User Interface (UI) has become a necessity due to the variety of the contexts of use. In this paper, we propose an approach based on models for the generation of adaptive UI. To reach this objective, we have made use of parameterized transformation principle in the framework of the Model Driven Engineering (MDE) for the transformation of the abstract interface into a concrete interface. The parameter of this transformation plays the role of the context of use. The paper develops two parts: meta-models for every constituent of the context of use and the adaptation rules.

In ubiquitous computing, the context of use (user, platform, environment) is in a permanent change. This has brought about new challenges in the Human Computer Interface (HCI) engineering to obtain User Interfaces (UI) that are compliant to their context of use. This paper has benefitted from the interests of parameterized principle transformation in the framework of the Model Driven Engineering (MDE) to propose approaches based on the models for the generation of the adaptable UI. It provides meta-models for the various components of the context of use which plays the role of the transformation parameter of the abstract interface into a concrete interface. It is through a case study of an information system of industrial supervision that the approach is shown to be reliable.

In recent years, given the development of networks and technological innovations, the user mobility has increased so much. That is why the interactive applications must be executed on both mobile devices as PDAs, mobile phones and PC. The user is then progressing in a varied and dynamic environment. Therefore, the challenges of the User Interface are related to the adaptation to the context of use. This paper describes a model-based approach to generate user interfaces adapted to their context of use, while respecting usability. The Model Driven Engineering is used to provide solutions to the problems of adaptation and usability and allow automatic generation of user interfaces. The case study pertaining to a tourist guide system is used to illustrate our approach. General TermsHuman Computer Interaction, Design.
