Model-based Solution for Personalization of the User Interaction in Ubiquitous Computing

Ubiquitous computing is strongly centered on the human, aiming to provide the right information through personalized interfaces and services in context of use to the applications users. We envision a ubiquitous computing based world in which a generic personalization model is applied to different applications, even if from different domains. The model is the core of a cloud-based platform, which guides developers by providing services to help them in the implementation of personalized solutions. Moreover, end-users will be less bothered when starting to use a new application, which already might know something about them in order to automatically adapt itself to the users' preferences and needs. A user's interactions with an application A might be useful to know how to personalize her experience when interacting with an application B. This paper presents the X-Users based solution in order to reach that vision, giving special attention to the personalization modeling. Important contributions of the paper are also two case studies that illustrate how X-Users can be used to help personalizing systems.
