Abstract
The recent development on pervasive computing, sensors network and smart appliances has motivated the appearance of new technological domain called smart spaces. such spaces are defined as a physical space rich in equipments and software services that is capable of interacting with people in order to provide intelligent services to the user for improved comfort (quality of life), energy saving, security, and tremendous benefits for an elderly person living alone. Providing intelligent services requires the equipments to be sensitive to the context of use or context-awareness. The concept of context is a key enabling factor in such environment and understand it, establishing its components and modeling it are basic and important steps for the development of smart spaces. Previous works in such environments were unable to deal efficiently with context awareness. In this paper we present both an ontology-based context and smart living room modeling.
