<P>PROBLEM TO BE SOLVED: To detect the rotation angle that can qualify biasing with dissolving defects of conventional footfall examination. <P>SOLUTION: A rotation angle detection device includes: a footstool on which a subject steps; includes means for acquiring the oscillating center position of the subject when the subject stands up on the footstool at a standstill before stepping by toe grounding method as a first coordinate, and acquiring the oscillating center position of the subject when the subject stands up at a position on the footstool at a standstill after stepping by the toe grounding method as a second coordinate; and means selecting the rotation center of a body on a line connecting right and left first toes grounding on the ground and to acquire the angle formed by a line connecting the rotation center and the first coordinate and a line connecting the rotation center and the second coordinate as a rotation angle generated by the rotation of the body. <P>COPYRIGHT: (C)2012,JPO&INPIT |
