<P>PROBLEM TO BE SOLVED: To provide a walking azimuth detection apparatus capable of speedily and highly accurately detecting a walking azimuth in the beginning of walking of a pedestrian. <P>SOLUTION: A walking azimuth detection apparatus 700 is configured to detect a walking azimuth of a person and has an acceleration component calculation section 730 for acquiring a perpendicular component and a horizontal component of an acceleration of the person and a walking azimuth calculation section 770 for determining the walking azimuth on the basis of time-sequential data of the perpendicular component and the horizontal component. When the perpendicular component presents minimal just after the person stops, the walking azimuth calculation section 770 defines an azimuth of the acceleration as a walking azimuth. <P>COPYRIGHT: (C)2012,JPO&INPIT |
