X-Putt : A Golf Putting Training System based on Ultrasonic sensors

In this paper, we propose a new golf putting training system which we call "X-Putt". X-Putt analyzes putting strokes by measuring putter face angle and path. To do this, we improved the sonar-based localization scheme used by previous localization techniques. As a result, X-Putt can measure putter`s location within the error range, and putter face angle within . Additionally, we built an user application that has an easy-to-use interface for analyzing the strokes after training.
