In recent years, many papers have demonstrated "ubiqui tous" services for indoor human location. Under the con ventional method of position detection, the major approach is to generate electromagnetic waves or light rays as in Ac tive Badge or RFID tags. However, in the case of practical applications for infant education, parents are wary of meth ods that employ radiated electromagnetic waves. In this article we propose a high-precision positioning system for children in a room, using only a combination of image data and passive motion sensors. We evaluate some alternative implementations experimentally. These evaluations probe whether the combination of a pedometer approach to ana lyze motion sensor data and moving-object detection from video camera images is the best combination with respect to ease of operation and accuracy. The proposed method cannot yet analyze data in real time. It may, however, be possible to apply the technique to various fields with little need for expansion, based on location information.
