A method and system for using a low resolution image of a golfer's swing for analysis is disclosed. Cameras obtain images of various portions of a golfer's swing. A computer calculates parameters associated with a golfer and a golf club from the images. Parameters include body angles, head position, shoulder positions, arm positions, hand positions, leg positions, foot positions, club shaft angles, and club head position. Different portions of the swing are captured using the cameras, including a static initial address, a backswing, a downswing, a forward swing, and a follow-through. A computer uses measured parameters from two or more portions of the swing to determine comparative parameters during different portions of the swing. The computer uses the parameters to generate swing analysis outputs, including swing characteristic information and/or swing profile information. A correlation table relates identified swing analysis outputs to recommendations to the golfer to improve the swing.

A golf swing training aid for teaching a golfer to maintain a steady head when swinging a golf club. The golf swing training aid comprises an elongated straight rod attached to the ground, a curved hose section slidable over the elongated straight rod which can be extended and retracted, a hose arc section which is formed from the curved hose when the curved hose is extended longitudinally, a constant tension stopper imparting a stopping action when the curved hose is extended longitudinally, a ball attached to the end of the curved hose, wherein a golfer attaches the elongated rod to the ground, extends the slidable curved hose over the elongated straight rod forming a hose arc section, adjusting the hose arc section to the proper height for the golfer's head to come in contact with the ball providing a steadying action for the golfer to learn to maintain a steady head when swinging a golf club.

An alignment aid for a golfer includes a handheld device with a direction finding device for determining a target vector (V1) with respect to a sighted target, a sensor device for determining a position vector (V2) as a measure of an instantaneous alignment of the golfer, and a display device. The alignment aid is operable to check an included angle (a) between the target vector (V1) and the position vector (V2) and to output a good signal (G) to the display device upon a successful check of the included angle.

A golf swing training device comprises an upwardly extending support to be positioned on the ground in front of a golfer; a visual guide mounted on the support; the visual guide including a golf-ball viewing window through which a golf-ball is viewed by the golfer. The size of the viewing window may be adjustable.

A modular head engaging assembly for use with a golf swing training device, the assembly including a U-shaped back-of-the-head positioning element including axially aligned inner and outer coupling pieces, the U-shaped back-of-the-head positioning element extending from a position adjacent the forehead of a golfer across the top of the head to a position overlying a portion of the rear of the head, a U-shaped collar element including axially aligned inner and outer coupling pieces, the U-shaped collar element being extending from a position adjacent the forehead of the golfer around each side of the head with a free end positioned above each of the ears, and a front head-positioning element including an inner coupling piece, the front head-positioning element being positioned adjacent the forehead. The three elements being coupled by the coupling pieces.

A golf training apparatus includes an elongated member having opposite first and second ends. A base is coupled to the first end of the elongated member; and the base includes an end portion to secure the apparatus in a stationary position so that the elongated member extends upward from the base. A top piece is coupled to the second end of the elongated member, and the top piece includes a sight through which a golfer may view a golf ball positioned near the base.

The three elements being coupled by the coupling pieces.

A golf training aid comprising a base, a support arm, and an alignment rod or guide, wherein the base is positioned in front of the target golf ball when the golfer is in position behind the target golf ball. The arm is attached to the base and is normal to the direction of the stroke or swing, wherein the alignment rod or guide is held by the support arm directly above the target golf ball as viewed by the golfer. The system may further comprise an adjustable, telescoping, stationary, or detachable pole with a camera mount and/or camera attached to the pole top and may comprise a camera mount under the base.
