Context-awareness and uncertainty: current scenario and challenges for the future

One of the main aspects of Ambient Intelligence (AmI) refers to its capacity of act autonomously in benefit of human beings. This implies in a hard challenge to overcome and of enormous responsibility. AmI is directly related to other fields of knowledge such as Smart environments, which aim to improve user experience through the development of context-aware applications. In this paper we present the current scenario of context-aware systems with some conceptual metrics to be followed. We highlight the problem of dealing with uncertain context information, e.g. incomplete, out-dated or nebulous data, seen as one of the main obstacle in this area.This work has been supported by COMPETE: POCI-01-0145-FE\-DER-007043 and FCT –Fundação para a Ciên-cia e Tecnologia within the Project Scope UID/CEC/ 00319/2013
