Rule based body mechanics calculation

Abstract

The invention is a motion training method. The motion of golf swing will be emphasized. In order to guide a golfer through a proper swing, his/her swing must be analyzed first. To analyze the swing, a set of frame photos will be needed. From those frame photos, the invented method will provide a rule based method to calculate the body mechanics/forces of the golfer. Once the body mechanics/forces are known, the system will then determine the swing is correct or incorrect. If the swing is incorrect, the system will then make suggestions to the golfer about how to correct his/her swing.
