Analysis of Cooperative Actions of Different Skill Levels Golfers

Abstract

In this study, we tried to analyze the relationship between cooperative action of golf swing and difference of skill levels. For extracting cooperative action from different swings, we conducted experiment of acquiring swing data. Subjects was a beginner and an intermediate, an expert golfer. We measured each golfer’s swings by motion capture system (VICON). We built observance matrix from acquired positional data and we conducted singular value decomposition (SVD) on this observance matrix. By conducting SVD, we extracted cooperative action as some independent modes. Then, we compared cooperative action of different skill levels subject on main mode. As a result, we reached the following conclusion that we could indicate some independent modes shown skill levels of golf swing.
