Current advances in portable devices and wireless technologies had drastically impacted mobile and pervasive computing development and use. Nowadays, mobile and or pervasive applications, are increasingly being used to support users' everyday activities. These apps either distributed or standalone are characterized by the variability of the surrounding environment, the constrained devices' characteristics and specifically the context they are used in. Building mobile apps that support the user while spanning different contexts and experiencing different situations, needs therefore to use relevant mechanisms dealing with mobility, context awareness, and adaptability. In this paper, we propose a new adaptable and re-configurable mobile Intelligent Tutoring System (ITS) architecture for acquiring relevant communication skills in different situations taking into account persons with specific needs. Adaptability and context awareness are addressed by combining and porting OSGi features and Semantic Web technologies on top of an Android platform.
