Abstract(in English) Research focusing on PDR (Pedestrian Dead Reckoning) is being conducted as it would be useful to support rescue activities for an injured people if the evacuation route of indoor evacuees can be recorded on a smartphone after a disaster such as an earthquake. In this paper, we propose a method to acquire the teacher data of the walking motion of the target user in advance in daily life and use it to estimate the moving state at the time of evacuation. For the features, the angle of the thigh detected by a rotation vector sensor, the time length of two steps, and acceleration values are used. Since it was clarified in the preliminary experiment that the features to be used for the judgment differ depending on the subject even in the same moving state, the majority of the judgment results based on these multiple sensor values were taken and used as the final recognition result. A recall rate was over 80% in each movement state of walking, running, descending stairs, and ascending stairs.
