In recent years, various sports are enjoyed among people, and undoubtedly, one of their major interests is to improve their own skills. Here, the sports which hit the balls can be classified in two types, hitting the moving ball or the fixed ball. The performance depends not only on the sports form but also the timing in case of hitting the moving ball, while the performance depends mainly on the sports form in case of hitting the fixed ball. This paper introduced a sports form training system for putting which is a typical case of hitting the fixed ball. Though various technologies have been introduced in the field of sports training, it is still a difficult task to gain an accurate sports forms through the sports training. This is because it is difficult to reflect the modification to the performer's own sense, and the modification itself is difficult to be understood when the performer is not self-training but being coached. In response, this paper introduced a new system which corrects the sports form by directly calibrating the sense of the body position using VR technologies. The system was developed based on hybrid learning method which focus one' s concentration on the sense of the body position while keeping the accuracy in the calibration. Finally, the effectiveness of the system was evaluated through comparison with conventional training method.
