Situation-Aware Smart Environment Modeling

The term ubiquitous smart system is utilized to characterize applications that are able to perceive the user context and properly react, according to the occurrence of specific events. Lately, several solutions have been developed in order to propose new approaches focused on ubiquitous computing, in general, not exploring a general model that could be broadly applied and calibrated respecting the context of interests of specific ubiquitous applications. In this sense the objective of this work is to propose a system model and functioning that is capable of recommending situation-aware actions to users, implemented in a Situation as a Service way. The system enables customized behavior, depending on user’s situation, which is the main research challenge considering that a number of context elements have to be evaluated. A use-case shows how ubiquitous applications can automatically define the user situations and recommend personalized actions within a residential home-care scenario.
