Disclosed is a self-contained device and method for improving a practicing golfer's swing which is brought about by the movement and action of an elongated headpiece subassembly which is positioned at the side or temporal areas of a practicing golfer's head and withdrawn when there is premature movement or glancing away from one's eye on the golf ball being hit prior to striking the golf ball in the practicing shot, or pulled away when the golf ball is struck without moving one's head or eyes prior to making the shot and proceeding with follow-through. In related preferred models of the invention a ground support subassembly assembly is used to vertically support the headpiece subassembly, and acts to define an area where the golf ball is placed for the practicing shot; and further provides a warning method when a right-handed or left-handed practicing golfer strays too far to the left or right, respectively in follow-through of a practicing shot.

A swing analysis device includes: an acquisition unit (swing video acquisition unit) acquiring a swing video of a user; a processing unit deciding an impact timing and a tempo, based on the swing video; and a display unit displaying the swing video and the tempo. The display unit, while displaying the swing video, displays the tempo when the impact timing is reached in the swing video.

Techniques are disclosed where computer technology is practically applied to solve the technical problem of helping golfers align their golf shots with respect to their targets. This technology can operate in coordination with an alignment device (e.g., an alignment stick) used by the golfer as an aid for aligning the golf shot with the target. In an example, the disclosed system can use image processing in combination with computer-based modeling of physical relationships with respect to an alignment device, ball, and/or target that exist in the real world to compute and adjust alignments for golf shots. This technology can provide real-time feedback to golfers for improved training and shot accuracy.

A golf training aid simulating a grass whip consists of a club shaft, a neck portion, and a blade portion. The blade portion is connected to the club shaft via the neck portion. The club shaft replicates the shaft of a golf club. The blade portion replicates the club head of a golf club. The weight for the blade portion is specifically selected so that the wrists of the user adjusts along with the swing. Moreover, the shape of the blade portion is specifically shaped to minimize air resistance. The shape of the blade portion also helps the blade portion to smoothly cut through grass. Since the apparatus helps the user practice on striking grass during a swing, when a golf club is used with a golf ball, the user can accurately strike the ball at an optimal contact point.

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 golf putting device includes a ball location for placing the ball, and at least three visual guides around the ball location. The visual guides serve to align the golfer's head and eye relative the golf ball so that all three guides are only visible when the golfer takes a position directly above the golf ball so as to improve putting consistency and accuracy.

A method is established to afford a golfer the opportunity to witness a golf swing in real-time fashion. Said method includes supplying a ground surface, a supplemental surface, and a source of light.

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.

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.
