Abstract:
1. An operations analysis apparatus for motion, comprising: a prescribed-motion data acquisition unit configured to acquire prescribed-motion data which is measured when an exemplar performs prescribed motions including a series of prescribed postures and motions, by using at least one motion measurement device which is attached to at least one part of the human body of the exemplar, and acquire prescribed-motion data which is measured when an examinee performs the prescribed motions, by using at least one motion measurement device which is attached to at least one part of the human body of the examinee, which corresponds to the at least one part of the human body of the exemplar; a corresponding interval extraction unit configured to extract the corresponding intervals between intervals of the prescribed-motion data for the exemplar and intervals of the prescribed-motion data for the examinee, from the prescribed-motion data for the exemplar and the prescribed-motion data for examinee; a feature extraction unit configured to, from the acquired prescribed-motion data, extract features of the acquired prescribed-motion data for the exemplar and features of the acquired prescribed-motion data for the examinee, for parts of the human body; a transformation matrix calculation unit configured to, on the basis of information for the corresponding intervals extracted thereby, calculate a transformation matrix for performing a transformation between the features of the prescribed-motion data for the exemplar and the features of the prescribed-motion data for the examinee, for the parts of the human body; a specified-motion data acquisition unit configured to acquire specified-motion data which is measured when the exemplar and the examinee perform specified motions, respectively, by using the at least one motion measurement device which is attached to the at least one part of the human body of the exemplar and the at least one motion measurement device which is attached to the at least one part of the human body of the examinee; a creation unit configured to, from the acquired specified-motion data for the exemplar, create exemplary specified-motion information for the examinee by using the transformation matrix; and an indication unit configured to indicate examinee specified-motion information based on the acquired specified-motion data for the examinee, and the created exemplary specified-motion information for the examinee so as to be associated with each other, wherein the prescribed-motion data acquisition unit is configured to acquire prescribed-motion data which is measured, by using at least one motion measurement device which is attached to at least one of a dominant hand and a dominant foot of the exemplar, and by using at least one motion measurement device which is attached to at least one of a dominant hand and a dominant foot of the examinee, wherein the operations analysis apparatus for motion further comprises a data transformation unit configured to, in the case where the exemplar is a right-handed person and the examinee is a left-handed person, or the exemplar is a left-handed person and the examinee is a right-handed person, perform a data transformation so that the prescribed-motion data for the at least one of a dominant hand and a dominant foot of the exemplar corresponds to the prescribed-motion data for the at least one of a dominant hand and a dominant foot of the examinee, and wherein the feature extraction unit is further configured to prevent discrepancies in the positions of the motion measurement devices between acquisition of the prescribed motion data and the specified motion data by measuring a set of specified motion data.
