Abstract

A method and system for training the movement of a golf club that includes a mobile device that receives positional data based on movement of a golf club and stores summation parameters of golf club movements in a trainee database. In addition, the mobile device builds a training envelope that determines the parameters for training and detraining movements. The mobile device then selects a best movement from a plurality of training iterations and outputs an instantaneous feedback based on the positional data during the training iterations. The best movement is the positional and rotational data generated by a best swing. A new best movement is determined from a training iteration that produces a better result than the previous movement.

Description

RELATED APPLICATION

The present application claims priority to U.S. Provisional Patent Application Ser. No. 61/844,793, entitled “SYSTEM AND METHOD FOR TRAINING MOVEMENT OF GOLF CLUB”, filed by Millers et al. on Jul. 10, 2013, the contents of which are hereby incorporated by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates generally to a golf swing training system, and, more particularly, to a golf swing training system that provides instantaneous feedback during the training movements.

BACKGROUND

Recently developed golf training systems include portable devices that are mounted on the exterior of a golf club. These systems include, for example, a detachable gyroscope that outputs a vibration alert to prevent the club face from improperly rotating on plane. Another training device includes a hinge system that breaks when the golf swing is not on plane.
Furthermore, other recently developed golf training systems include a memory that stores golf swing data during golf training iterations, These systems provide non-instantaneous feedback via a display such as a mobile device or the like. Specifically, these systems typically output a chart to a golfer that shows the scalar results of a single golf swing. However, the golfer is not provided with any instantaneous guidance as how to correct any deficiencies in the golf swing to further improve the swing.

SUMMARY

According to one or more embodiments of the disclosure, a mobile device may receive positional data based on movement of a golf club and store parameters of each golf club movement in a trainee database. In addition, the mobile device may build a training envelope that determines the parameters for training and detraining movements. A best movement may then be selected from a plurality of training iterations by the mobile device. The training envelope may be a range of deviation from the best movement parameters and may be a set of positional and rotational values that define the range of values included in a successful training movement, The mobile device may then output an instantaneous feedback during the training iterations based on the received positional data. The trainee database may include a current training level, a current improvement rate, quantitative improvement over training duration, quantitative improvement per training iteration and session, definitions of best movement, definitions of training movement, and definitions of detraining movements. The training movements may be golf club movements within the training envelope parameters and the detraining movements may be golf club movements beyond the training envelope parameters, The instantaneous feedback, which may be an audio response, may also indicate whether the golf movement conforms to or is beyond the training envelope.
In addition, the mobile device may adjust the training envelope parameters as the training movement is repeatedly performed. During periodic training, the mobile device may select a new best movement when the parameters of a golf club movement have improved beyond the previous best movement parameters. This new best movement may be a condition for outputting a positive instantaneous feedback and a detraining signal may be output by the mobile device in response to detecting a golf club rotation or position (e.g., movement) beyond the training envelope parameters. The parameters for training and detraining movements may include accuracy of golf club positioning, accuracy of a swing movement (e.g., a stroke movement), a back, swing distance control, and an even acceleration of a swing. Then, in response to reaching a training threshold, the mobile device may reset the training and detraining parameters of the training envelope and may continuously compare a current level of performance with the new best movement to output instantaneous feedback and to continue improvement of the golf club movement.

FIGS. 1A-1B are exemplary diagrams of the golf training system according to an exemplary embodiment of the present invention. As shown in FIG. 1A, the golf training system may be embedded within a golf club 105 and may include a sensor unit 110 mounted above and/or within the club head and configured to collect data regarding the club head and orientation of the golf club from a plurality of sensors. Specifically, as shown in FIG. 1B, the sensor unit 110 may include a plurality of sensors such as accelerometers 115, gyroscopes 120, and magnetometers 125 that may indicate a precise repeatable club head starting position. In addition, as seen in FIG. 2, the sensor unit 110 may be a sensor computational device 215 that has a processor 220 and a memory 225. The processor 220 may be configured to receive the collected data from the gyroscopes 120, the accelerometers 115, and magnetometers 125 and store the data in the memory 225. In addition, the sensor computational device 215 may be configured to compute positional data from the sensor data.
Further, the sensor computational device 215 of the golf training system may be configured to communicate the positional data wirelessly (e.g., via Bluetooth, WiFi, cellular service, etc.) with a mobile computational device 210 (e.g., a mobile phone, a smart phone, a personal digital assistant, etc) as shown in FIG. 3, In other words, the sensor computational device 215 and the mobile computational device 210 may be configured to communicate wirelessly. Additionally, the mobile computational device 210 may be configured to output audio commands related to the golf training movements and output voice recognition responses.
Referring to FIG. 4, the mobile computational device 210 may include a microprocessor or a processor 305 which may be configured to receive the sensor positional data instantaneously from the sensor unit 110 via a sensor receiver 310. In addition, based on the golf club training movements (e.g., training iterations), the processor 305 may be configured to establish and store a most desirable club head movement (e.g., best movement) in a memory 315 (e.g., a trainee database) to continuously compare instantaneous club head location and rotation with the best movement (e.g., the expected and desired club head movement). When the processor 305 has compared the instantaneous data with the best movement data using a plurality of algorithm calculations, the processor 305 may output feedback (e.g., audio response) via an audio output transmitter 320, thus providing both positive and negative feedback to a golfer during the training of the golf club movement. The processor 305 may be configured to store in the memory 315 (e.g., trainee database) a plurality of parameters such as a current training level, a current improvement rate, quantitative improvement over training duration, quantitative improvement per training iteration and session, definitions of best movement, definitions of training movement, definitions of detraining movements, and the like.
Furthermore, the processor 305 of the mobile device 210 may be configured to build a training envelope that determines parameters for training and detraining movements and may be modified to control and drive trainee learning. The training envelope may be a set of positional and rotational values based on multiple swings performed during training movements. In other words, when a golf swing is within the range training parameters of the envelope, the swing may be considered a training movement. The parameters for training and detraining may include accuracy of golf club positioning, accuracy of a swing (e.g., stroke) movement, back swing distance control, even acceleration of the swing, and the like. Specifically, the precise swing parameter may be how a golf club orientation is adjusted to move through the golf ball substantially orthogonal to where the face of the golf club is pointing. The back swing distance control involves the starting position of the swing at a designated point and the golf club backswing point to achieve a designated distance. The combination of the accuracy of golf club positioning and accuracy of swing movement parameters may minimize angular deviation of the golf ball movement, In addition, the combination of the back swing distance control and even acceleration of the swing parameters may increase the precision of distance control.
As a golfer improves a golf swing (e.g., reaches a training threshold), the training envelope may decrease toward the parameters of the selected best movement. Alternatively, when a golf swing is beyond the range of the training envelope parameters, the golf swing may be considered to be a detraining movement. Thus, the mobile device may output instantaneous feedback on the deviation of the swing to training envelope parameters, thereby providing instantaneous feedback based on the movement of the golf club and not on the results of striking a golf ball. FIGS. 5A-5C show exemplary graphs of deviations for a training envelope for various parameters taken into account to form the training envelope. For example, as seen in
FIG. 5A, when a golf swing is within the training envelope (indicated by the arrows) of the various parameters (e.g., A, B, and C, such as rotational angle, club head speed, etc.), a positive feedback may be output. Alternatively, as seen in FIG. 5B, when a golf swing is determined to be beyond the training envelope for the various parameters of the training envelope, a negative feedback may be output. In other words, the mobile computational device 210 may be configured to output an instantaneous feedback based on whether the particular golf swing is within a training envelope parameters.
Additionally, the mobile computational device 210 may be configured to determine whether a particular golf swing is beyond the training envelope at various points in time, as illustrated in FIG. 5C. In other words, the mobile computational device 210 may be configured to determine whether a golfer is within training envelope parameters throughout each movement of the golf club until the swing is complete. For example, in FIG. 5C the dashed lines indicate a training envelope for a complete golf swing and shows a best movement 510 that is within the training envelope. When a golfer performs a successive swing, a negative feedback may be output at time t3 since at that particular time, the movement is beyond the training envelope parameters.
Moreover, when a negative feedback is output to a golfer, the golfer may interpret the feedback as an instruction to abort that particular swing. Thus, negative learning may be minimized and the analysis of the swing may be improved. Additionally, a positive feedback may be an indication of continuous tracking of the best movement. In one exemplary embodiment, when the positive feedback is no longer output (e.g., the positive feedback is lost), the output is not repeated. In other words, the goal of a golfer may be to maintain the positive feedback output for as long as possible. Accordingly, the golf club movements of an entire golf club swing may be monitored.
A golfer may therefore, adjust the movement of the golf club, based on the feedback to improve consistency of a golf swing. For example, the output feedback may provide the physical state of a golf club movement as an audio tone. Additionally, different audio tones may be output for different states of the golf club movement and a golfer may interpret the various tones as either positive feedback or as a correction tone. The mobile computational device 210 may be configured to only output a negative feedback when the golf club movement is beyond the training envelope parameters. Thus, the golfer may immediately be provided with a measure of deficiencies in the golf swing. When a golfer swings a new best movement, the mobile device may select the new best movement (e.g., a better movement than the best movement) to further improve a golf swing. Notably, the feedback output is not limited to an audio tone and may be any other audio response known to those skilled in the art capable of providing feedback on deviation correction. In addition, each new best movement operates as a condition for outputting positive feedback and the training envelope provides boundary conditions for outputting negative feedback.
Moreover, the phenomenon of repeating the golf club training movement while learning a selected best movement is known to those skilled in the art as cerebellar learning. Specifically, as the training movement is learned or modified, a portion of the movement control is also learned and thus, under the control of the cerebellum, may be come unconscious learning. Since the cerebellum stores both training and detraining movements, the golf training system of the present disclosure focuses on improving the training movements by outputting feedback when a golf swing is within the training envelope parameters and when the golf swing is beyond the training envelope parameters. In addition, the feedback helps ensure that the majority of training iterations are training movements and helps ensure consistency of a golf swing. The efficiency of skeletal training (e.g., the rate at which a trainee learns) is dependent on reaching an optimum ratio of training movement to detraining movements. As the trainee improves the training movements and reaches a predetermined training threshold, the parameters of a training envelope (e.g., boundary conditions) may be modified to maintain the optimum ratio.
FIG. 6 illustrates an exemplary simplified procedure 600 for training the movement of a golf club according to an exemplary embodiment of the present disclosure described herein. The procedure 600 may start at step 605, and continues to step 610, where a mobile device selects a best movement based on received positional data from a plurality of training iterations. In step 615, the mobile device builds a training envelope that determines the parameters for training and detraining movements. The training envelope may be a set of positional and rotational values. In step 620, a mobile device receives positional data based on movements of a golf club and then in step 625, instantaneous feedback may be output during the training iterations based on the received positional data. The instantaneous feedback may indicate the deviation of golf club movements determined to conform to or be beyond the training envelope parameters. In step 630, the mobile device stores summation parameters of golf club movements in a trainee database. Then, the process may illustratively repeat to step 620 or end in step 635.
Note that the functional blocks, processes, devices and systems described in the present disclosure may be integrated or divided into different combinations of systems, devices, and functional blocks as would be known to those skilled in the art. The foregoing description has been directed to specific embodiments. It will be apparent; however, that other variations and modifications may be made to the described embodiments, with the attainment of some or all of their advantages. Accordingly, this description is to be taken only by way of example and not to otherwise limit the scope of the embodiments herein. Therefore, it is the object of the accompanying claims to cover all such variations and modifications as come within the true spirit and scope of the embodiments herein.
