In this study, we developed a method for estimating an arrangement of functional joint rotation centers (FCRs) from a set of body dimensions. For this purpose, we measured body dimensions and positioning motions for 20 subjects, and calculated their FCRs. Using principal component analysis, information on the arrangement of the FCRs was represented by six principal components. Multiple regressions functions to estimate scores of these principal components from body dimensions were calculated. The arrangement of the FCRs could be reconstructed from principal component scores, which were estimated from body dimensions. The arrangement of the FCRs was estimated for members of boundary family of a digital manikin system.
