Smart spaces are ordinary environments equipped with visual and audio sensing systems, pervasive devices, sensors, and networks that can perceive and react to people, sense ongoing human activities and respond to them. Their ubiquity is evident by the fact that various state of the art smart spaces have been incorporated in all situations of our life. These smart space elements require middleware, standards and interfacing technologies to manage complex interactions between them. Here, we present an overview of the technologies integrated to build Smart Spaces, review the various scenarios in which Smart Spaces have been incorporated by researchers, highlight the requirements of software infrastructure for programming and networking them, and mention the contemporary frameworks for interaction with them.
