Description
CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority under 35 U.S.C. § 119 to Great Britain Patent Application GB 2304916.6 filed Apr. 3, 2023, which is herein incorporated by reference in its entirety, including without limitation, the specification, claims, and abstract, as well as any figures, tables, appendices, or drawings thereof.


The present invention relates to a golf training apparatus and/or to a method of use thereof.


Although the following description refers almost exclusively to golf training apparatus for use on or with a golf putter, it will be appreciated by persons skilled in the art that the present invention could be used on or with any type of golf club, such as for example, a wood, a driver, an iron, a hybrid, a wedge, a putter and/or the like, or even any similar task which requires the performer to coordinate action where precise aim and intentional alignment is essential for a successful outcome.


In order for a golfer to improve their performance, it is important for them to regularly train and receive accurate feedback on the position of their golf club at different sections of their golf swing, the timing and movement of their golf swing and the orientation of their golf club relative to an intended target. Many golfers have a personal golf coach to verbally provide this feedback to them during a golf lesson. However, regular use of a personal golf coach is expensive and therefore prohibitive for many golfers, and it does not help when the golfer is practising on their own.


In an attempt to overcome this problem, there are a number of golf training aids that are available in the marketplace that provide automatic feedback to a user in order to help them improve their golf performance. Many of these golf training aids are in the form of inertial measurement units (or IMUs) that are attached or detachably attached to the user and/or to a part of the user's golf club, with the majority of such aids being attachable to a shaft of the user's golf club. Such aids are able to capture a large range of statistical measured data relating to, for example, the impact position of a golf ball with the club head, swing data, speed data, positional data, player movement data and/or the like. The aids can store this data for later retrieval and/or can communicate the data to a user's mobile phone, with a separate or remote electronic unit or computer, with a user's smart watch and/or similar. However, problems associated with these type of devices are that they are either not calibrated or, if they are calibrated, the calibration is not accurate or tends to drift over time and use. As such, the user may be required to constantly re-calibrate the training aid, which is time consuming and is likely to put the user off from regularly using the training aid. The position of some of the current IMUs on the golf club can significantly alter the weight and feel of the golf club, thereby resulting in the user's training position being different to the user's competition position, such that trained positions and techniques are not readily transferable to competition positions and techniques. Yet further, many of the current training aids only provide information on where the golf club shaft is in three dimensional space and not where the golf club head that will actually impact the golf ball is, or any information on where the golf club head is relative to a target the golfer might be aiming for. Many current training aids also do not take into account the interaction that emerges between the golfer, the task and their environment. As such, the prior art provides only limited feedback information and application for allowing improvement of a user's golf performance.


It is therefore an aim of the present invention to provide golf training apparatus that overcomes the abovementioned problems.


It is a further aim of the present invention to provide a method of using golf training apparatus that overcomes the abovementioned problems.


According to a first aspect of the present invention there is provided golf training apparatus according to claim 1.


Thus, the apparatus of the present invention provides a means of calibrating or re-calibrating the sensing means or other sensing means associated with the golf club to at least one known target, other than a golf ball, in use. This significantly increases the accuracy of the data being generated and/or collected by the sensing means and/or apparatus and helps to reduce or prevent drift of the apparatus and/or sensing means, parameter measurements/data accuracy over time and use. The resulting apparatus can be relatively simple and more cost effective to produce and use compared to conventional training aids, and can allow a greater range of performance statistics to be captured by the apparatus. For example, the apparatus can be used to provide direct or indirect feedback on at least one measured parameter which is specific to the user, their equipment and/or performance. In addition, or as alternative, the apparatus can be used to provide user feedback based on an ecological dynamics training method, as is explained in more detail below. An advantage of this is that one or more constraints can be added, modified and/or removed using the apparatus to provide augmented feedback to the user.


Furthermore, the apparatus of the present invention can be used to augment the player/user undertaking kinaesthetic imagery, simulation of a golf swing task without a golf ball and/or the rehabilitation of golf swing motor skills. For example, use of the apparatus of the present invention to aid sensory motor learning, guidance and rehabilitation of impairments such as Vision, Focal Dystonia and Parkinson's Disease and/or the like in golf players.


Detection of the at least one target means is used to calibrate or re-calibrate the sensing means to an absolute point of physical reference for calibration or as zero, thereby generating absolute golf club orientation data (i.e. in the world coordinate system). This allows one or more parameters subsequently measured by the sensing means, one or more other sensing means and/or one or more associated IMUs to be calibrated relative to the target/sensing means calibration value.


In one embodiment the sensing means, first sensing means, second sensing means and/or further sensing means are a sensing device, first sensing device, second sensing device and/or further sensing devices respectively.


In one embodiment the target means is a target or target apparatus.


In one embodiment the pre-determined value to which the sensing means is calibrated to can be changed and/or adjusted in use, thereby allowing re-calibrating of the sensing means in use. This can allow adjustment of one or more constraints placed on the user using the apparatus in use. For example, the target means could be moved or the pre-determined value allocated to the target means can be changed and/or adjusted.


Preferably examples of the one or more constraints that can be altered using the apparatus of the present invention can be the position of the at least one target means in use and/or the like.


In one embodiment detection of the at least one target means by the sensing means allows a distance of the sensing means and/or golf ball from the at least one target means to be measured or calculated and/or calibration of the sensing means includes measuring or calculating the distance of the sensing means and/or golf ball from the at least one target means. Knowing how far a golf ball and/or the sensing means is from the at least one target means allows other parameter calculations to be accurately measured, thereby providing enhanced feedback to a user.


Preferably the distance measurement between the sensing means, the at least one target means and/or the golf ball is via a triangulation process or mathematical triangulation process. For example, any conventional mathematical triangulation process can be used to measure the distance.


In one embodiment an initial approximation of the distance of the sensing means and/or golf ball from the at least one target means is determined during an initial detection stage of the sensing means with the at least one target means. Once the at least one sensing means has detected the position of the at least one target means, refinement of the approximate distance then takes place using a mathematical triangulation process to provide an accurate distance of the sensing means and/or golf ball from the at least one target means. In one embodiment the sensing means is arranged to sense one or more parameters, in addition to sensing the at least one target means.


In one embodiment the golf training apparatus includes and/or is associated with one or more other sensing means and/or IMUs (i.e. separate and/or different to the target sensing means). Preferably the one or more other sensing means and/or IMUs are arranged to sense, detect, measure, generate and/or calculate one or more parameters. These parameters may be the same and/or different to the one or more parameters detected, sensed, measured, generated and/or calculated by the target sensing means.


In one embodiment the one or more other sensing means and/or IMUs can be coupled by wired or wireless means, physically coupled, directly or indirectly coupled and/or communicatively coupled to the target sensing means in use or to micro-processing means associated with the target sensing means.


Preferably the one or more other sensing means and/or IMUs can be calibrated and/or re-calibrated using the at least one detected target sensing means calibration data.


In one embodiment, the target sensing means are arranged to lock onto the at least one detected target means in use to allow continuous or substantially continuous calibration and/or re-calibration of the sensing means, one or more other sensing means, IMUs and/or apparatus in use.


Preferably the sensing means is continuously or substantially continuously searching for and/or detecting the at least one target means in use, thereby allowing continuous or substantially continuous calibration and/or re-calibration of the apparatus, sensing means, one or more other sensing means and/or IMUs in use.


In one embodiment the calibration and/or re-calibration of the apparatus, sensing means, one or more other sensing means and/or IMUs in use is arranged to take place live and/or in real time.


In one embodiment the calibration and/or re-calibration of the apparatus, sensing means, one or more other sensing means and/or IMUs takes place a pre-determined time after the at least one target means has been detected and/or after one or more parameters have been detected by the target sensing means.


In one embodiment the apparatus, the sensing means, the one or more other sensing means and/or the IMUs includes timing means and, once the at least one target means has been detected by the sensing means, the timing means is arranged to provide one or more time based markers. Thus, for example, a time based marker can be associated with the calibration, re-calibration, the one or more parameters sensed by the sensing means or other sensing means and/or the like.


Preferably the timing means allows time based event markers to be generated; temporal data to be generated relating to any time point or points during a golf swing or action epoch, temporal golf club orientation data to be measured, sensed, calculated, generated and/or the like using the apparatus. For example, the one or more time based markers can be used with other quotients in a golf action epoch and/or golfing environment to calculate rolling resistance, one or more surface artifacts, topography and/or the like.


In one embodiment a combination of the distance measurement of the sensing means and/or golf ball from the at least one target means and the one or more time based markers allow one or more parameters to be calculated, alone or in combination with data from other sensing means, such as for example, time to ball impact and/or time of ball flight to be measured and/or calculated. In some embodiment an accurate time to ball impact and/or time of ball flight may also require ball tracking data from ball tracking sensing means. The ball tracking sensing means can form part of the present invention in one embodiment.


Preferably the data gathered from the one or more other sensing means and/or IMUs is typically relative golf club orientation data (i.e. on a local club coordinate system) but the use of and/or combination with the calibration data generated by the target sensing means, provides absolute golf club orientation data to be generated by the apparatus from all sensing means and/or IMUs associated with the apparatus.


Preferably the timing means is in the form of a timing device, clock and/or the like.


In one embodiment the sensing means includes first sensing means and at least second sensing means (also referred to herein as other sensing means).


Preferably the first and at least second sensing means are located or locatable in different positions on or in the apparatus, the golf club, the golf ball, on or with a user of the apparatus; are located a spaced distance apart and/or remote from each other, sense one or more different parameters, relate to different golf training systems and/or the like.


In one embodiment the sensing means, the first and/or the at least second sensing means is any sensing means or device that allows the sensing of its position relative to the at least one target means in use, such as for example, optical sensing means or device, ultrasonic sensing means or device, magnetic sensing means or device, radio wave sensing means or device, laser sensing means or device and/or the like.


In a preferred embodiment first sensing means is in the form of an optical sensor, such as a camera or image capture device for example.


Preferably the at least second sensing means is in the form of or includes one or more inertia measuring units (IMUs), global positioning systems (GPS), optical sensing means or device, accelerometers, golf training systems and/or the like.


The sensing means, or the first sensing means is provided on, in, associated with and/or locatable with a head portion of a golf club in use. By providing sensing means that can be provided on, in and/or associated with the head portion of a golf club in use and can sense the position of itself with respect to the at least one target means, this allows the golf training apparatus to provide more accurate and useful data on the orientation and/or location of the head portion of the golf club relative to the target means at any point in the golfer's swing, action epoch or movement. The data that can be generated by the apparatus of the present invention is more useful, has wider application and is more applicable to the normal movement patterns of a golfer's swing compared to prior art training systems. In addition, by providing the sensing means or first sensing means in association with the head portion of the golf club, this allows the weight distribution of the golf club to be more aligned to that of a conventional golf club that might be used in golf tournaments/competitions, thereby providing a more accurate training aid for the golfer.


In one embodiment the one or more parameters being sensed in use and/or the data on which the apparatus can generate includes any or any combination of the movement of the golf club; movement of the golf club head portion; the direction of movement of the golf club; the direction of movement of the golf club head portion; the direction the sensing means is pointing in (and therefore, for example, the direction the golf club or golf club head portion is pointing in) relative to the at least one target means; the speed of movement of the golf club head portion and/or golf club; the position of the golf club or golf club head portion relative to the at least one target means in use; the distance the sensing means and/or a golf ball is from the at least one target means and/or the like.


The golf club on which the sensing means or first sensing means is provided in use includes a shaft portion and a head portion located at an end of said shaft portion. Preferably at least part of the shaft portion is arranged to be gripped in the hands of a golfer/user in use, and typically at an end opposite from the head portion end of the shaft portion.

In one embodiment the optical sensing means or device is continuously or substantially continuously taking images, “snap shots”, video, image data streams and/or the like during use of the apparatus.


In one embodiment the optical sensing means or device is arranged to capture one or more images, “snap shots”, video, image data streams and/or the like based on the one or more pre-determined parameters. For example, the one or more pre-determined parameters could include one or more pre-determined time points, one or more pre-determined positions, one or more pre-determined speeds or accelerations and/or the like.

In one embodiment the at least one target means is a final target a golfer is trying to hit a golf ball to for a shot.


In one embodiment the at least one target means may not be a final target a golfer is trying to hit a golf ball to for a shot, but may, for example, be a temporary target that can be removed after calibration. For example, the at least one target means may be a temporary target the head portion of the golf club may need to face or point towards in order for a golfer to hit a golf ball to a different final target in use.

Embodiments of the present invention will now be described with reference to the following figures, wherein:



FIG. 1 is a simplified view of apparatus according to an embodiment of the present invention;



FIG. 2 is a simplified view of apparatus according to a further embodiment of the present invention;



FIG. 3 is a simplified schematic view of apparatus according to a yet further embodiment of the present invention.





The present invention relates to golf training apparatus that can be used to bring about an improvement in skill acquisition, movement education and/or the performance of a user or athlete. It can also be used to augment player/user undertaking kinaesthetic imagery of a golf swing task without a golf ball and/or the rehabilitation of the golf swing motor skills. In particular, the apparatus is used to improve the adaptive movement patterns of a user or athlete using theory based, at least in part, on ecological dynamics.


Ecological dynamics is a scientific framework that looks at how living organisms form processes of action, behaviour and cognition in the environment that the organism is operating in, rather than independently of the organism's environment. This framework has allowed an athlete training method to be developed called “Constraints-Led Approach” or CLA. The CLA method of training takes a holistic and individual approach to learning by considering the interactions between different “constraints”; the performer, the environment and the task being performed. The apparatus of the present invention provides a means of prescriptive and/or corrective feedback personal to the athlete/performer in one embodiment but also provides the means to allow use of the CLA training method to allow manipulation of the constraints placed on the athlete/performer in one embodiment.


The three underlying concepts of the CLA training method are:

    • a) Interacting constraints—including performer constraints, such as for example height, strength, mood or motivation; environmental constraints, such as for example weather, terrain, gravity, obstacles and the like; and task constraints, such as for example, equipment, rules, objectives and the like.
    • b) Perception-Action Coupling—the learning pathway of an athlete as they link what they see and what they do.
    • c) Human body self-organization in order to produce functional movement.


The apparatus of the present invention can be used in either or both an indoor or outdoor environment and provides augmented feedback to a user (also referred to as an athlete or performer) of the apparatus. The feedback can include physically recorded data feedback and/or cognitive feedback. The apparatus can be used to control, challenge and/or adjust one or more of the three underlying concepts in one example.


The apparatus of the present invention and the feedback produced by the apparatus can be used in a way to improve the adaptive movement of the user or athlete.


Referring to FIG. 1, there is illustrated golf training apparatus 2 according to an embodiment of the present invention. The golf training apparatus 2 is for use on a golf club, which in this illustration is a golf putter 4.


The golf putter 4 includes a putting shaft portion 6 having a first end 8 and a second opposite end 10. The shaft portion 6 is elongate and is arranged for a golfer to grip the same in their hands adjacent first end 8 in use.


A head portion 12 is provided at the second end 10 of shaft portion 6. The head portion has a golf ball impact surface 16 for impacting with a golf ball 18 in use.


The golf training apparatus 2 includes sensing means in the form of a sensing unit 20 that is attached laterally of the head portion 12 via attachment means. In this example, the attachment means is in the form of a band 22 but it will be appreciated that any suitable attachment means could be used to attach the sensing unit to the head portion 12 in use.


A front surface 24 of the sensing means is aligned or substantially aligned with the golf ball impact surface 16 of the putter head portion 12 such that the entire front surface of the golf ball impact surface and front surface 24 are planar or substantially planar. As such, the sensing means is facing the same direction as the impact surface 16 of the putter head portion 12 in use.


The sensing unit 20 in this example is an optical sensor in the form of a camera 25, with a camera lens 26 for capturing visual data, images and/or video in use. However, other sensing means could be used.


The apparatus 2 further includes optical or visual target means in the form of target 28 that is portable and can be moved to a suitable location by a user in use. The target 28 is separate to and independent of the sensing unit 20 and can be moved to a remote location with respect of the sensing unit 20 in use.


In the illustrated example the target 28 includes a base portion 30 for supporting the target 28 on a ground surface in use and a visual target portion 32 protruding upwardly from the base portion 30. A visual image, which in this example is a bullseye image 34, is provided on the visual target portion. However, other fiduciary markings can be provided on the target portion that are detectable by the camera in use.


The visual bullseye image 34 is visually distinguishable from the background against which the target 28 is placed in use.


The target 28 can be a final target the golfer may be trying to hit the golf ball 18 to, such as a putting hole, or it could be an intermediate target that the impact surface 16 of the putter head portion 12 has to face and be aligned with in order for the ball to reach a different final target, such as the arrangement shown in FIG. 2.


The apparatus 2 can also include micro-processing means 35 for processing the images captured by the camera and for extracting data relating to the position and/or direction of the putter head portion 12 relative to the target means 28, the distance the sensing means is from the target means 28, the speed of movement of the putter head portion 12, the timing of the movement of putter head portion 12 and/or the like. One or more algorithms can be used by the micro-processing means to extract data from the captured images to provide feedback data to the golfer that can be used as a valuable and accurate training tool.


For example, in use, the camera 25 searches for and detects the fiducial marker 37 on the target 28, as shown in FIG. 3. The camera 25 then locks onto the detected target 28 and, using the micro-processing means 35, calibrates itself to the target, with the target being absolute zero or some other pre-determined calibration value. As such, any other measurements and/or images taken using the apparatus can be calibrated based on the position of the target with respect to the camera 25. A timer can also be provided or associated with the processing means such that the calibration is also undertaken with respect to time in one embodiment. Thus, the apparatus is able to generate temporal data at any one or more point or points within a player's swing or action epoch that is calibrated relative to the target. One or more other sensors, such as for example other IMUs 40, can be used with the apparatus 2 to provide feedback data for a user based on one or more pre-determined measured parameters. The micro-processing means 35 can process this data from the other IMUs to provide augmented feedback to a user of the apparatus. The other IMUs can be calibrated using the calibration data calculated between the camera 25 and the target 28. The apparatus can therefore calculate absolute orientation of the camera 25 relative to the target and provide low time granularity image data. The micro-processing means 35 and the other IMUs provides high time granularity to provide absolute orientation and relative data respectively.


Thus, according to FIG. 3, the optical camera sensor 25 on the golf club detects the target 28 and the targets associated fiducial markers 37. The target 28 can be a single or final target comprising fiducial markers or the target 28 can comprise at least one permanent target, such as located at the hole/flag, and at least one temporary target, both of which comprise fiducial markers.


Using the micro-processor 35, the data from the optical camera sensor 25 is used to generate absolute (i.e. in the world coordinate system) golf club orientation information at a relatively low temporal frequency.


Using the micro-processor 35, the data from the IMU sensor 40 is used to generate relatively high temporal frequency golf club orientation information. This is typically relative (i.e. in the local club coordinate system).


The micro-processor uses the combination of the signals from the optical camera sensor 25 and the IMU sensor 40 to provide relatively high frequency absolute golf club orientation information (i.e. in the world coordinate system).


The IMU sensor 40 (which can include a plurality of IMU sensors if required) can additionally detect relevant event markers throughout the golf action epoch.


It will be appreciated that the direction of arrows in FIG. 3 can be one direction or bi-directional as required.


The apparatus 2 can also include data storage means to allow data to be stored in use. This allows a user to study data after they have finished a training session. However, live data could be provided in one example if required.


The apparatus 2 can include power supply means to allow power to be provided to the camera and/or the micro-processing means.


User feedback means, such as for example a wrist band, augmented superimposed optical information displayed through wearable glasses, and the like, with an optical display, could be provided to signal to a user whether the camera is aligned/calibrated with the target 28 in use. For example, a green light could be displayed on the wrist band if the sensing unit 20 is correctly aligned/calibrated with the target 28 or a red light could be displayed on the wrist band if the sensing unit 20 is incorrectly aligned/calibrated with or out of sight of the target 28.


Referring to FIG. 2, a further embodiment of the present invention is described. The same references are used to describe the same features shown in FIG. 1. In FIG. 2, a second visual target 36 is provided. In this example, this second visual target means 36 is located at a putting hole 38 the golfer is trying to hit the golf ball 18 into in use.


The micro-processing means can triangulate the position of the first visual target 28, the second visual target 36 and/or the sensing unit 20 to allow data to be extracted relating to the position, the distance, movement and speed of the putter head portion 12 with respect to the first and/or second targets during a golf swing in use.
