The Dualism of Context in Ubiquitous Computing

Context-aware systems are fundamental for making the use of computing devices intuitive.These systems respond to their environments to facilitate seamless interactions between the users and their computing devices, and to make these devices less intrusive.Although it is more than a decade since context-aware systems were introduced, context is still not well understood within a context-awareness research community.Although there are numerous definitions of context, these definitions refer to context as an input or as a derivable.The majority of researchers believe any input that makes a context-aware system to accomplish its task is a context.In the contrast, there is handful of researchers who believe context is derived from more than one inputs.This paper aims to provide a clear meaning of context and consequently to resolve the differences between researchers regarding context.In particular, this paper answers the most fundamental, but yet the most avoided, question; what is context?
