MOTION SENSING DEVICE, MOTION SENSING METHOD, AND MOTION SENSING CIRCUIT

摘要

PROBLEM TO BE SOLVED: To detect a motion of an object without using an acceleration sensor or a gyroscope.;SOLUTION: This device is equipped with a geomagnetic sensor 11 having one or more axes, for detecting a geomagnetic component; a geomagnetic component information storage part 12 for storing information of the geomagnetic component detected by the geomagnetic sensor 11 as geomagnetic component information; and a determination part 18 for determining the motion of the object based on the geomagnetic component information stored in the geomagnetic component information storage part 12.;COPYRIGHT: (C)2009,JPO&INPIT
