| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Recently, it is possible to use various network connections at several location using mobile devices. There are some services for mobile devices which makes use of location information. For these services, it is necessary to estimate the location of the moving mobile devices. It is well-known that we can use the GPS in order to obtain the absolute position of the device. On the other hand, it is possible to employ dead-reckoning method adopted by the conventional car navigation system using built-in sensors to obtain the relative movement of the device. 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. We evaluate the proposed method in terms of the estimation accuracy by fi eld experiments when we adopt the Kalman fi lter algorithm by using the absolute location information and the relative movement information. From the results of our fi eld experiments, we show that the proposed method using the sensor information outperforms the conventional estimation method without it. |
