A smart home 3D modeling approach for spatiotemporal analysis

Abstract

Indoor location systems allow for the integration of more and more daily life objects into the smart home environment model. Consequently, managing the spatiotemporal data of things is becoming increasingly challenging. In this article, we propose a 3D geometrical approach to spatiotemporal object management and analysis based on the adaptation of the spatial database concept. We use the DOMUS apartment at Université de Sherbrooke as a reference environment for 3D modeling of smart homes. We present a sample of 3D spatial analysis functions implemented in the DBMS to illustrate the use of the geometric model in providing smart home indoor location-based services. © 2012 Springer-Verlag.
