A Context Information Management System for Context-Aware Services in Smart Home Environments

摘要

In recent years, context-aware systems that exploit a variety of context created in the smart home environment to provide information and services to users have been studied. Existing context-aware systems determine the environment's state (context) based on isolated context data from individual devices or sensors. In addition, there has been little attempt to infer the inhabitants' needs or preferences from the sensed context. This paper examines the characteristics of context recognition based on the context information created in the smart home environment and suggests a way to provide context-aware services using the inhabitants' behavior patterns. The context information management system proposed in this paper analyzes context information to identify patterns, conflicts and faults in a smart home environment.
