| Abstract(in English) | There are many difficulties in representing accurate movement of the joints of the human body. Not only are there many different types of joints, but joints also vary from person to person. We propose a method to estimate the shape of the articulatio radiocarpalis (wrist joint) as an ellipsoid joint, and how to represent the joint in SE(3). First, the motion of the wrist joint is recorded using an optical motion capture system and estimate the shape of the ellipsoid using the path of the motion data. Next, we define the ellipsoid joint as a matrix in SE(3) using Lie groups. Finally, We also present how to calculate the kinematics of the joint as the joint representation, and then compare our ellipsoid joint to a traditional ball joint model in order to evaluate the joint movement. Our ellipsoid joint can model the movement of the human wrist more accurately than the ball joint model as an ellipseal shape is more similar to a real human wrist joint. |
