Using dual number method for motion analysis of left arm in a golf swing

Abstract

A traditional method in capturing of human motion is using the cameras. The camera method, although widely used, has it own limitations. This paper presents a different way of capturing the human motion. The method involved utilizing electrogoniometer (biometrics, UK) to obtain the joint angles throughout the motion and by using dual Euler angles and dual Euler velocity analysis, the location and velocity of the measured segment or endeffectors can be estimated. This paper explores the possibility of using goniometer to measure the anatomical rotations and using dual number theory for the analysis of the swing.
