Abstract: An object of one or more embodiments of the method presented is to provide an analysis of swing features relative to a target line. To accomplish this, a golfer selects a target line, which is an imaginary line connecting the position of a strike object, such as a golf ball, with an intended target. The target line is stored on a mobile device. A sensing unit attached to a golf club captures orientation and acceleration data during a swing, which is analyzed relative to the intended target, against a baseline swing model. The method also provides feedback on golf club position when the golfer is addressing the ball, prior to the backswing. The golfer receives feedback on swing performance swing performance relative to the target line for each club and various swings types, such as chips or bunker shots.
