Design and Basic Experiment of Online Feedback Training System for Golf Putting

The purpose of this study is to develop an online feedback training system for golf putting that can improve the repeatability without affecting the swing feeling. By using the proposed system providing auditory feedback in real time, the repeatability of the swing can be improved in the same swing feeling as a game. To realize this system, an IMU (inertial measurement unit) is attached on the grip end of the putter and measures the angle of putter head. This mounting position of the IMU was examined and designed. In addition, the authors experimentally determined the maximum weight of the mountable IMU without affecting swing feeling. As a results, it turned out that up to 10g IMU can be attached on the club. Moreover this system gives auditory feedback corresponding to the loudness and the angle of the putter, therefore, users can know the angle of the putter head in real time. In particular, this paper reports on the proposal and evaluation experiments of this system.
