| Abstract(in English) | Recently, it is possible to use various network connections at any time or any place using mobile devices. There are some services for mobile devices using the network connectivity. In the services such as navigation systems, it is necessary to estimate the location of the mobile devices. We can use the Global Positioning System (GPS) in order to obtain the absolute position of the device. However, the absolute position estimation by the GPS strongly depends on circumference environment. So, we need a location estimation system which is able to adapt to the GPS environment change. On the other hand, there are some relative movement estimation methods by dead-reckoning techniques. The dead-reckoning can estimate the relative movement by the sensors. The latest mobile devices such as the smartphone are equipped with some sensors to capture the behavior of the device for entertainment. In this paper, we propose a new location estimation method which combines the absolute location information by the GPS with the relative movement information by the Sensors. From the results of our field experiments, we show that the proposed method using the sensor information outperforms the conventional estimation method without it. |
