Semantics and Modeling of Indoor Moving Objects

Moving objects in indoor space has been a research focus in recent years, as most people live and work in indoor space, e.g. working in office, living in apartment, etc. In this paper, we make a first step in indoor moving object management. We focus on the conceptual modeling of indoor space as well as indoor moving objects, and aim to describe the semantics and properties of indoor moving objects. Firstly, a conceptual modeling framework for indoor space is defined, based on which we propose a semantic description of indoor moving objects. Compared with previous models, our model takes into account the relationships among rooms, doors, sensors and moving objects, and uses a layered approach to represent indoor space and indoor moving objects. The model proposed can be further extended to meet different needs in indoor moving object monitoring and tracking.
