CRITiCAL: A Configuration Tool for Context Aware and mobiLe Applications

This paper presents an approach for modelling and generating Context-Aware and Mobile (CAM) applications based on (i) Model-Driven Engineering and (ii) context acquisition middleware concepts. Our approach allows software engineers to build CAM applications by modelling contextual information and rule-based behaviour on a visual notation. These graphical models are transformed into an Android-based code, targeted for a context-aware middleware called LoCCAM, which encapsulates device sensors access. An initial user evaluation conducted with a group of fourteen computer science volunteers was implemented and indicates time reduction gains in the middleware configuration process and that the complexity in the writing of contextual behaviour of applications is also decreased.
