In this work, we propose a real-time golf learning system using visual feedback. The system projects the visual feedback which is imitating shadow on the ground in front of the learner. It makes it possible for the learner to receive the feedback without the posture collapse. The learner can receive the feedback with the fixed face orientation as the actual golf swing, which could not be solved in existing systems projecting feedbacks on the wall. Furthermore, a posture difference is provided by projecting the expert's outline on the learner's virtual shadow. In addition, because shadow was also used in golf practice conventionally, the cost of adaptation to this learning system which uses virtual shadow as visual feedback may be low.
