<p><P>PROBLEM TO BE SOLVED: To detect the posture of a subject easily and accurately. <P>SOLUTION: Each of individual magnetic flux emitting sections 211<SB>j</SB>(j=1, ..., N) emits a detection magnetic flux having frequency directivity of a predetermined frequency band. The individual magnetic flux detecting sections 130A<SB>1</SB>-130A<SB>3</SB>arranged on the forehead and both temporal parts, upon receiving the detection magnetic flux, emit reporting magnetic flux having directivity carrying identification information thereof toward the individual magnetic flux emitting sections emitting the detection magnetic flux. The individual magnetic flux emitting sections 211<SB>j</SB>receiving the reporting magnetic flux read the identification information of the individual magnetic flux detecting sections. A reception reporting section 215 then transmits the identification information of the individual magnetic flux detecting sections and information of the individual magnetic flux emitting sections reading the identification information to a processing section. Subsequently, the processing section specifies a rotation angle of the head around an individual axis from a reference head posture on the basis of the mounting positions of the individual magnetic flux detecting sections emitting the reporting magnetic flux and the arranged position of the individual magnetic flux emitting sections receiving the reporting magnetic flux. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
