<P>PROBLEM TO BE SOLVED: To provide a motion detector capable of detecting the fine motion of an object to be detected. <P>SOLUTION: The motion detector 1 comprises: an acceleration detection means 2 mounted on a human body 9 for detecting triaxial accelerations; an angle calculation means 31 for calculating an angle θ between a first acceleration vector and a second acceleration vector on the basis of the first acceleration vector of the human body at the certain point of time acquired by the acceleration detection means 2 and the second acceleration vector of the human body at the point of time after the lapse of prescribed time from the certain point of time; and a motion detection means 32 for detecting the motion of the human body 9 on the basis of the angle θ calculated in the angle calculation means 31. <P>COPYRIGHT: (C)2008,JPO&INPIT |
