Claim 6:
7. The method according to claim 1, further comprising:
acquiring, by the processor, additional sensing information of an additional sensor attached to an additional target part of the body of the subject, the additional sensing information including additional quaternion information;
detecting, by the processor, an additional attaching direction of the additional sensor with respect to an additional reference direction defined based on the additional target part, wherein the additional reference direction remains the same relative to the additional target part when a position of the additional sensor with respect to the additional target part changes;
executing, by the processor, tagging processing for associating the additional attaching direction of the additional sensor with additional sensing-related information related to the additional sensing information, the additional sensing-related information including the additional sensing information and additional information obtained by converting the additional quaternion information into rotation angle information
calculating, by the processor, a motion state index of the target part based on an information difference between the quaternion information of the sensor and the additional quaternion information of the additional sensor, wherein the motion state index is a three-dimensional angle of the target part; and
outputting, by the processor, the motion state index.
