This invention is related to a motion training/reforming method. Using a video camera to record an action and later reviewing each frame to analyze the movement, is a common practice in many sports. For instance video a golfer's swing and analyze it later. This has already been done for many years. In fact many patents have already been issued for methods which analyze golf swing by using video photos (see Background Art (1), (2) and (3) above).

U.S. Pat. No. 5,823,878 discloses a certain method of analyzing a golf swing by using video photos. The foundation of this method is completely based on motion capturing technology. A set of 3D -points on the golfer's body and club is captured. The (x, y, z)-coordinates of those 3D -points are calculated from at least two sets of photos taking at different angles. Then the body mechanics of the golfer are calculated by processing those captured 3D points with certain general processors.

Any motion, in general, is dominated by certain physical laws/rules. For example, a golf swing is dominated by the following two physical rules (see Other Reference [1] above), i.e. during the swing,

(1) the golfer's upper body rotates around his/her backbone and

(2) the backbone is almost constantly pointing at a fixed direction.

However, these physical rules are completely ignored by U.S. Pat. No. 5,823,878. If those rules can be used in the calculation of the body mechanics, all the complicated system and processes such as motion capturing mentioned in U.S. Pat. No. 5,823,878 will become unnecessary.

Starting with a set of frame photos, this invented method will use a set of physical rules (including those mentioned above) and a set of 2D lines to calculate the body mechanics/forces of the golfer. Once the body mechanics/forces are known, we will have the essential information of the golfer's swing. This essential information will then provide the golfer with a clue of how to correct his/her movement.

Although the motion of golf swing is emphasized, the application of this invented method will not be limited to the golf swing.

Although this invented method can be applied to different kinds of motions, in order to make things clear we will concentrate our motion just on golf swing. A good golf swing is composed of correct body, hip, arm and club movements. The object of this invented training method is to help train a golfer to move his/her body, hip, arm and club correctly.
