摘要
An X-factor feedback apparatus senses three-dimensional direction information of the shoulder and the pelvis in a golf swing motion of a user, collects, synchronizes and stores the sensed three-dimensional direction information, analyzes the change of angle in the three-dimensional direction information based on the stored data information, extracts a backswing top point in the swing motion, evaluates the degree of twist of the shoulder and the pelvis based on the angle in the three-dimensional direction information of the shoulder and the pelvis at the backswing top point, and provides a feedback to the user.
