Functional Joint Rotation Centers for Whole Body Digital Manikin

In order to adapt actual motion data of a person to a digital manikin, we developed a method of estimating the functional joint rotation centers for the whole manikin body. By using this method, the positions of joints in motion can be estimated if the length of each segment of the whole body remains constant. As a result, when the digital model of the whole body moves, the trajectory of the most distal end is more similar to that of an actual human than the trajectory of the whole body model estimated using a conventional method.
