In sports like golf, the motion of a club or racket determines the outcome significantly, and it is essential to consistently move such properties with the correct forms to achieve high scores during competitions. This paper proposes a novel projection method that provides real-time visualization of golf club trajectories on the ground. The system can render the trajectory of a golf club along with conventional face-to-path angle information in real-time using an optical motion capture system and a video projector. Furthermore, the system utilizes dynamic changes of color to provide more detailed information about the pose of the golf club. This color-changing method aims to help users understand their club motion trajectories and explicitly adjust their form based on the visualization results.
