Perceptual Components for Context Aware Computing

Abstract

In this paper we propose a software architecture for observing and modeling human activity. This architecture is derived from an ontology for context awareness. We propose a model in which a user's context is described by a set of roles and relations. Different configurations of roles and relations correspond to situations within the context. The components of a context model are used to specify processes for observing activity. The ontology for context modeling is derived from both a bottom up system's perspective and a top-down users' perspective. As we define each element, we describe the corresponding components of a process-based software architecture.
