Systems, methods, and other embodiments associated with instruction production are described. In one example, a system can comprise a difference component that makes an identification of a difference between an actual action of a user and a standard action for the user. The system also can comprise an instruction component that produces an instruction to instruct the user to change from the action of the user to the standard action for the user, where production of the instruction is based, at least in part, on the difference. The system further can comprise a non-transitory computer-readable medium configured to retain the instruction. Additionally, the system can comprise an output component configured to cause disclosure of the instruction.

A system and method for analyzing and improving the performance of a body motion of an animal or human subject requires instrumenting a subject with inertial sensors, monitoring a body motion of interest, converting sensor data into motion data and animation, comparing the motion data with existing data for motion related performance parameters, providing a real-time, information rich, animation and data display of the results in color coded displays; and based on the results prescribing a training regime with exercises selected from a library of standardized exercises using standardized tools and training aids.

A golf training device that is affixed to to the arm and hand of the golfer-in-training in order to control the range of hand movement during the downswing of a golf swing. The device having multiple embodiments that cooperatively controls hand to wrist angles in order to keep the hands in the proper position throughout the swing. More descriptively, the device allows complete range of motion of the hands except in the extended or downward direction after initiation of the swing. In a golf swing it is important to disallow movement in the downward direction once the golf swing has been initiated, but it is also important to allow full and natural freedom of movement every other direction so a golfer-in-training does not feel uncomfortable or restriction while practicing. The present invention as constructed also allows the device to return to the natural address position upon completion of the swing.

Disclosed are various embodiments of golf training device that helps a golfer learn and coordinate lower body positions and movements with upper body movements, using a series of feedback signals. These signals force a lifted Lead Heel and bent Trail Knee starting at the beginning of the backswing and force the downswing to begin by replacing the Lead Heel while the Trail Knee is still bent. In one embodiment, among others, a system comprises a foot sensor that attaches to a Lead Foot of a user. The foot sensor is configured to detect a heel of the Lead Foot being raised. The system also comprises a leg sensor that attaches to a Trail Knee of the user, and the leg sensor detects a bend in a knee of a Trail Leg of the user after detecting the heel being raised. The foot sensor is configured to detect the heel being lowered at an instance after the detection of the bend in the knee of the Trail Leg and while the knee remains bent. The system further comprises a feedback device configured to activate one or more feedback indicators after the detections of foot and/or leg movements.

An electronic golf aid system for assisting users with reading greens on golf courses includes a camera that captures images of the user's field of view, and an electronic display device with a display screen that displays captured images. A processor, which communicates with the camera and display device, is programmed to: receive signals from the camera indicative of images of a golf ball and a cup on the green; determine respective locations for the golf ball and cup; determine a perspective view of the topology of the green between the golf ball and cup from the user's point of view; determine, based on the green's topology, a proposed trajectory line from the golf ball's location to the cup's location; and direct the electronic display device to display the proposed trajectory line superimposed on the surface of the green as the green is shown in real-time on the display screen.

Improvements in a golf grip hand structure efficiency device and a method of using the device are disclosed. The device is used determine a value of a parameter for a golfer called a golf grip hand structure efficiency. A golfer's determined golf grip hand structure efficiency value may be applied to create proper base gripping and swinging structures for the golfer for use in applicable swing improvement and/or clubfitting processes.

A golf training aid that may be attached to any golf club that may force a golfer's hands into the proper grip position for various types of golf shots is provided. The device and methods of the present disclosure may further allow a golfer to practice these shots to build muscle memory and to ingrain the proper grip positions into memory to allow for repeated and consistent shot performance.

A training aid for aiding a swing of a person at striking a ball such as in golf. The training includes a first arm cuff and at least one leg cuff with an intermediate connector having at least one resilient member. In this way the at least one resilient member extends in use between a trailing upper arm or above elbow of the player and the player's front lower torso or leading leg which in use aids the user by ensuring the large muscle of the trailing upper arm UA in a cocked elbow formation starts the down swing and aids the correct sequence of movement.

A method and system for improving the accuracy of putting a golf ball that includes a golf glove for use with a putter grip that has a straight edge, with the golf glove having a visual line alignment feature/illustration that allows a golfer to place his or her hand in a repeatable, proper position on the grip of the putter. The golf glove employed is devoid of any putter attachment feature, such as hook-and-loop fastener material on the glove or the golf grip and is further devoid of any indicia affixed to the back-hand portion of a glove that could be viewed as an alignment indicia, as it only complicates and confuses a golfer when putting. Preferred embodiments include a golf glove that includes a marking forming a straight line that diagonally crosses the palm portion of the glove such that, when worn by a wearer, provides the wearer with a visual indication of the proper gripping position of a golf putter, such putter having a grip that has at least one flat surface and an edge extending down the axial length of the grip that can be aligned with the visual indicator markings/line on the golf glove.
