Description

BACKGROUND
• The present invention generally relates to golf clubs and, more particularly, to a system and method for recommending an optimal golf club grip for an individual using dynamic indicators on a smart grip.
• Golfers of all skill levels have experienced times when a shot goes astray. Some lesser experienced golfers find this is the case a majority of the time. There are hundreds of elements that factor into the trajectory and distance of a shot and a significant part of those are found in the grip position of the club, i.e., the position of the user's hands holding the golf club during the swing. Golfers frequently find that there are too many dynamics and “things to remember” to affect a shot the way they want it. The way an individual holds the golf club in their hands, in particular the grip position of their hands on the golf club grip, is a significant factor that affects the flight of the ball for any given golf swing.
SUMMARY
• In a first aspect of the invention, there is a method that includes: obtaining, by a computer device, ball lie data; determining, by the computer device, an optimal grip position for a golf club based on the ball lie data and historical shot data of a user; and transmitting, by the computer device, data defining the optimal grip position to a smart grip attached to a shaft of the golf club.
• In another aspect of the invention, there is a computer program product that includes a computer readable storage medium having program instructions embodied therewith. The program instructions are executable by a computing device to cause the computing device to perform the following steps for a plurality of golf shots by a user: determine ball lie data of a respective one of the plurality of golf shots; determine a golf club used for the respective one of the plurality of golf shots; determine a grip position of a user's hands on a grip of the golf club during the respective one of the plurality of golf shots; determine a result of the respective one of the plurality of golf shots; and save an entry in a database for the respective one of the plurality of golf shots, wherein the entry contains data defining the ball lie data, the golf club, the grip position, and the result.
• In another aspect of the invention, there is a smart grip system that includes: a grip material structured and arranged to fit on an end of a shaft of a golf club; a processor embedded in the grip material; an array of visual indicators connected to the grip material and operatively connected to the processor; and an array of pressure sensors connected to the grip material and operatively connected to the processor; wherein the processor is configured to selectively activate a subset of the array of visual indicators to visually indicate a suggested grip position for a user's hands on the grip material.

DETAILED DESCRIPTION
• The present invention generally relates to golf clubs and, more particularly, to a system and method for recommending an optimal golf club grip for an individual using dynamic indicators on a smart grip. According to aspects of the invention, a smart grip for a golf club includes numerous visual indicators (e.g., LED lights) below the grip material which can be programmatically lit to indicate an ideal hand/grip position for a particular type of golf swing for an individual golfer. In embodiments, the smart grip communicates with a computing device of the individual to record shot metrics. The computing device uses a database of the individual's historical shooting metrics to determine an optimal grip position for that individual in that type of approach, and then sends a signal to the indicators of the smart grip to light up and visually indicate the suggested optimal hand grip position. The database may also include historical shooting metrics for other users, which would enable the user to select another user's data (e.g., a golf instructor or professional) to have the smart grip indicate how the other user grips the club to accomplish a specific shot.
• In embodiments the computing device is a mobile computing device such as a smartphone or tablet computer. The system utilizes wireless communication between the smartphone and the smart grip. An application (e.g., an app) on the smartphone records the individual's current distance to the green, lie, and the approach angle. The application has access to a database of the individual's historic shooting metrics (e.g., distance, straight, slice, hook, loft) for respective combinations of swing parameters (e.g., club, grip position, lie). The application uses the database to determine an optimal club and grip position on the club to provide the highest probability (based on this individual's historic shooting results) of achieving a shot that satisfies the current distance to the green, lie, and the approach angle. The application then causes the smartphone to send a signal to the selected club that causes a subset of the indicators in the smart grip of the selected club to light up to indicate the determined grip position. The system may be operated in a learning mode to populate the database of the individual's historic shooting metrics. The system may also accept user input of an intent for a particular shot (e.g., high loft) with a particular club (e.g., seven iron), and use the indicated intent in determining the optimal club and grip position on the club.
• In additional embodiments, the system may be configured to compare the individual's current ball lie data (e.g., distance to the green, lie, and approach angle) to historical shooting metrics of other golfers who had the same (or substantially similar) ball lie data. The historical shooting metrics of other users may be used to determine an optimum grip for the current user's ball lie data by analyzing grips used by other users for historical shots for the same ball lie data, and assigning higher weight to grips that resulted in more successful historic shots and lower weight to grips that resulted in less successful historic shots. In embodiments, the historical shooting metrics of other users may be filtered by club brand and/or model, i.e., to match the club brand and/or model used by the current user.
• The present invention may be a system, a method, and/or a computer program product at any possible technical detail level of integration.

• FIG. 2 shows a block diagram of an exemplary system in accordance with aspects of the invention. The system includes asmart grip70 that is configured to be physically connected to agolf club72 taking the place of a conventional grip on thegolf club72. In implementations it is envisioned that a respectivesmart grip70 will be provided on each non-putter style golf club in a golfer's bag, e.g., on all the wood and irons. In embodiments, thesmart grip70 includes agrip material74, a processor76 (e.g., a computer microprocessor), a power source78 (e.g., a battery), aradio communication antenna80, an array of pressure sensors82 (indicated by hexagons inFIG. 2), and an array of indicators84 (indicated by triangles inFIG. 2). Thesmart grip70 may also include other sensors such as anaccelerometer86.
• Thegrip material74 may be any conventional or later developed golf club grip material such as natural rubber or synthetic rubber. Thegrip material74 may have a hollow cylindrical shape that is configured to fit snugly on an end of a shaft of a golf club. In embodiments, theindicators84 are on, or embedded in, thegrip material74 at a plurality of defined locations around the grip. Theindicators84 may comprise light emitting diodes (LEDs) or other visual indicators that can be selectively activated and deactivated (e.g., turned on and off). In one example, theindicators84 are sandwiched between two layers of thegrip material74 with the outer layer of the grip material being sufficiently thin such that anindicator84 that is activated (e.g., emitting light) can be seen through the outer layer of the grip material. A location of eachindicator84 may be defined in a coordinate system relative to thesmart grip70 and provided to theprocessor76.
• In embodiments, each of theindicators84 is operatively connected to theprocessor76 and powered by thepower source78. Theprocessor76 controls (e.g., selectively turns on and off) eachindividual indicator84 independent of the other indicators. Theprocessor76 is configured to selectively activate (e.g., turn on) a subset of theindicators84 to illuminate positions on thesmart grip70 where the user is suggested to place their fingers and thumbs. Theprocessor76 can activate different subsets of theindicators84 to indicate different grip positions. In this manner, thesmart grip70 can dynamically change different indicated grip positions on a same golf club. Moreover, pluralsmart grips70 may be used on plural golf clubs (e.g., onesmart grip70 per golf club) to create a system that can dynamically indicate an optimal grip position on a selected club for any given golf shot.
• FIGS. 3 and 4 depict implementations of asmart grip70 dynamically indicating different grip positions on a golf club.FIG. 3 shows thesmart grip70 with a first subset of theindictors84′ activated to indicate a first grip position on the golf club.FIG. 4 shows the samesmart grip70 with a second subset ofindicators84″ activated to indicate a second grip position on the same golf club, the first grip position being different than the second grip position. In embodiments, the activatedindicators84 visually indicate locations where the user should place their finger tips and thumb on the surface of thesmart grip70. Eachindicator84 may be a dual color LED such that a first color light can be emitted byindicators84 for finger locations, and a second color light (different from the first color) can be emitted by anindicator84 for a thumb location.
• Referring back toFIG. 2, according to aspects of the invention thesmart grip70 also includes a plurality ofpressure sensors82 on, or embedded in, thegrip material74 at a plurality of defined locations around the grip. Thepressure sensors82 may piezoelectric pressure sensors, for example. Eachpressure sensor82 is operatively connected to theprocessor76 and powered by thepower source78. The array ofpressure sensors82 is configured to detect the locations of the user's hands on thesmart grip70 when the user grips the club, e.g., during a golf swing. A location of eachpressure sensor82 may be defined in a coordinate system relative to thesmart grip70 and provided to theprocessor76.
• According to aspects of the invention, thesmart grip70 communicates viaradio communication antenna80 with auser device100, which may be any suitable mobile computer device such as a smartphone or tablet computer. Theuser device100 may comprise one or more elements of thecomputer system12 as shown inFIG. 1. For example, theuser device100 may comprise aCPU16, amemory28, and adisplay24. Thememory28 may store applications including agrip app106 and amap app108 that are executed by theprocessing unit16. Thegrip app106 andmap app108 may be similar toprogram module42 ofFIG. 1. Thememory28 may also store adatabase110 of a user's historical shooting metrics. Thedisplay24 may comprise a touch screen display that outputs an electronic visual display and that receives user input via stylus and/or finger touch. Theuser device100 may also include aradio communication antenna112 and be configured for wireless communication via at least one of cellular, WiFi, Bluetooth, and near field communication (NFC). Theuser device100 may also include alocation determining module114, such as a GPS (global positioning system) receiver.
• In accordance with aspects of the invention, thegrip app106 determines an optimal grip position on a golf club for the user, and transmits data to thesmart grip70 that causes theprocessor76 of thesmart grip70 to activate a subset of theindictors84 that correspond to the determined optimal grip position (e.g., as shown inFIGS. 3 and 4). In embodiments, thegrip app106 determines the optimal grip position using data that defines the golf ball lie and data of the user's historic shooting metrics.
• The data that defines the golf ball lie (also called ball lie data) can include one or more of: ball location, distance from the ball location to the green, ball lie angle (e.g., flat lie, uphill lie, downhill lie, side hill lie), and ball lie surface (e.g., fairway, rough, sand). In embodiments, the ball lie data is automatically obtained via theuser device100. For example, themap app108 may store map data that defines a map of the golf course on which the user is currently playing golf. The map data may define terrain (e.g., flat lie, uphill lie, downhill lie, side hill lie) and surface (e.g., fairway, rough, sand) for locations on the golf course. The map data may also define a location of the green for each hole of the golf course. Thelocation determining module114 of theuser device100 may be used to determine a GPS location of the golf ball lie. Using this GPS location of the golf ball lie, themap app108 may use the map data to automatically determine a distance from the ball location to the green, ball lie angle (e.g., flat lie, uphill lie, downhill lie, side hill lie), and ball lie surface (e.g., fairway, rough, sand). Themap app108 may pass the determined ball lie data to thegrip app106 for use in determining the optimal grip position.
• In a manual embodiment, the ball lie data may be determined manually via user input. For example, thegrip app106 may display a user interface on the display of the user device and prompt the user to manually input data that defines distance from the ball location to the green, ball lie angle (e.g., flat lie, uphill lie, downhill lie, side hill lie), and ball lie surface (e.g., fairway, rough, sand). For example, the user may tap a location on a map displayed in a user interface of theuser device100 to indicate the desired location of the golf ball on the golf course, and this location may be used as part of the ball lie data. Moreover, the user may provide input to the user interface to indicate the ball lie angle and the ball lie surface.
• In a hybrid embodiment, the ball lie data may be determined automatically in the manner already described herein and then confirmed or adjusted manually via user input. For example, upon receiving the automatically determined ball lie data from themap app108, thegrip app106 may display the determined ball lie data in a user interface on a display of theuser device100. The user interface may be configured to permit the user to provide an input to confirm (e.g., accept) the determined ball lie data or to change one or more parameters of the ball lie data. For example, the automatically determined ball lie data may indicate that the ball is on a side hill lie, and this may be displayed on theuser device100. The user may determine, however, that the ball is actually on a flat lie, and provide input to theuser device100 to change the ball lie data from side hill lie to flat lie. The user may change the data for each of the ball location and the lie surface in a similar manner. When the user confirms the ball lie data including any changes, thegrip app106 then uses the user confirmed data as the ball lie data.
• In embodiments, upon determining the ball lie data, thegrip app106 compares the ball lie data to the user's historical shooting metrics, which may be stored in a database on theuser device100. The database may categorize the user's own historic (past) golf shots based upon ball lie data, club data, grip position data, and resultant shot metrics. For example, the database may contain plural entries, with each respective entry corresponding to a respective historic (past) golf shot performed by this user. A respective database entry may include ball lie data for a historic golf shot, including ball lie angle (e.g., flat lie, uphill lie, downhill lie, side hill lie), and ball lie surface (e.g., fairway, rough, sand). The same entry may also include club data for the same historic golf shot, the club data indicating which club was used for the golf shot. The same entry may also include grip position data for the same historic golf shot, the grip position data indicating the locations of the user's hands on the smart grip, determined in a manner described herein. The same entry may also include resultant shot metrics data for the same historic golf shot, the resultant shot metrics data defining how far the ball traveled (shot distance) for this shot. The resultant shot metrics data may also define whether the shot was one of straight, slice, and hook. The resultant shot metrics data may also define an amount of loft for the shot, e.g., low loft, medium loft, high loft. The resultant shot metrics data may also define a strength of swing, e.g., half swing or full swing. The resultant shot metrics data may also define an amount of divot for the shot, e.g., no divot, small divot, large divot.
• According to aspects of the invention, thegrip app106 is programmed to determine an optimal club and an optimal grip position based on the ball lie data and the user's historical shooting metrics. In one exemplary embodiment, thegrip app106 identifies a subset of the database entries that all have a same ball lie angle and ball lie surface as the current ball lie data. Thegrip app106 may then categorize the subset of entries into club sets according to which club was used for each historic shot, e.g., based on the club data for each entry. For example, when the current ball lie data is for a flat lie in the fairway, thegrip app106 may identify from the database all the historic shots in which the user swung a three iron from a flat lie in the fairway, all the historic shots in which the user swung a four iron from a flat lie in the fairway, all the historic shots for which the user swung a five iron from a flat lie in the fairway, and so on until all of the historic shots matching the current lie and surface are categorized according to club.
• After categorizing the historic shots into club sets according to the club used for each shot, thegrip app106 may then categorize each club set into grip sets according to grip position that was used for each historic shot, e.g., based on the grip position data for each entry. For example, for the historic shots in which the user swung a three iron from a flat lie in the fairway, thegrip app106 may categorize these shots according to a first grip position, a second grip position, and a third grip position. Similarly, for the historic shots in which the user swung a four iron from a flat lie in the fairway, thegrip app106 may categorize these shots according to a fourth grip position and a fifth grip position, and so on until all the club sets have been categorized according to grip position data.
• After categorizing the historic shots by club and then grip position, thegrip app106 may determine an average shot result for each grip category for each club, based on the resultant shot metrics data from the database. For example, thegrip app106 may determine an average shot distance, average shot direction (e.g., straight, slice, hook), and an average shot loft (low, medium, high) for the group of historic shots in which the user swung a three iron from a flat lie in the fairway using the first grip position. Similarly, thegrip app106 may determine an average shot distance, average shot direction, and an average shot loft for the group of historic shots in which the user swung a three iron from a flat lie in the fairway using the second grip position. Similarly, thegrip app106 may determine an average shot distance, average shot direction, and an average shot loft for the group of historic shots in which the user swung a three iron from a flat lie in the fairway using the third grip position. Similarly, thegrip app106 may determine an average shot distance, average shot direction, and an average shot loft for the group of historic shots in which the user swung a four iron from a flat lie in the fairway using the fourth grip position. Similarly, thegrip app106 may determine an average shot distance, average shot direction, and an average shot loft for the group of historic shots in which the user swung a four iron from a flat lie in the fairway using the fifth grip position. Thegrip app106 can repeat the process until an average shot distance, average shot direction, and an average shot loft are determined for each grip set for each club set.
• Still referring to this exemplary embodiment, thegrip app106 then determines an optimal club and grip position for the current ball lie data based on the determined average shot distance, average shot direction, and average shot loft are for each grip set for each club set for all historic shots having the same ball lie angle and ball lie surface as the current ball lie data. For example, thegrip app106 may be programmed by default to filter out club and grip combinations that have a determined average shot direction of hook or slice. Then, from the remaining club and grip combinations that have a determined average shot direction of straight, thegrip app106 may be programmed to determine the club and grip combination that has a determined average shot distance that most closely matches the distance to green of the ball lie data for the current shot. For example, thegrip app106 may determine that for the ball lie conditions of the current shot, using the four iron with the fifth grip position is the optimal combination of club and grip.
• In embodiments, the database (e.g., database110) may also include historical shooting metrics for other users different than the current user. The historical shooting metrics for other users may be categorized in the same manner as the historical shooting metrics. For example, the historical shooting metrics for other users may include ball lie data, grip position, and resultant shot metrics for shots that have been made by other users. In this manner, thegrip app106 may determine an optimal club and grip position for the current ball lie data using the other users' historical shooting metrics. When historical shooting metrics of other users is utilized in this manner, thegrip app106 may optionally be configured to only use historical shooting metrics of other users that used a same brand and/or model of golf club as the current user. An exemplary implementation of using historical shooting metrics of other users is for thegrip app106 to provide a suggested club and grip to the current user, e.g., upon request of the current user, where the suggested club and grip is determined based on how other users have successfully handled the ball lie data faced by the current user.
• In embodiments, upon determining the optimal club and grip combination for the ball lie data for the current shot, thegrip app106 transmits data to thesmart grip70 of the selected club. The transmitted data causes theprocessor76 of thesmart grip70 to activate a subset of theindicators84 to light up and identify the determined optimal grip position. Continuing the example in which the four iron with the fifth grip position is the determined optimal combination of club and grip, thegrip app106 would cause theuser device100 to transmit data to thesmart grip70 on the four iron, and this data would cause theprocessor76 in thesmart grip70 on the four iron to activate a subset of theindicators84 to light up in positions that correspond to the fifth grip position. In this manner, implementations of the invention may be used to provide a suggested optimal golf club and grip position for a current ball lie, where the suggested optimal golf club and grip position are personalized to the user based on the user's own past shot history.
• In accordance with additional aspects of the invention, thegrip app106 may determine an optimal grip for a user-selected club based on an intent that is input by the user. For example, the user may select their club (without a recommendation from the grip app106) and input an intent for the current shot via a user interface on theuser device100. The intent may alternatively be entered via an input mechanism on thesmart grip70, such as a series of buttons or touch sensitive inputs on the smart grip that can be used to indicate one of: hook, slice, low loft, and high loft. The intent may be, for example, high loft (e.g., to shot over a tree), low loft (e.g., to shoot under tree), slice (e.g., to curve around an obstacle), hook (e.g., to curve around an obstacle). Thegrip app106 may use the intent in the determination of the optimal grip for this user-selected club, along with the ball lie data and the historic shot data as described herein. For example, when the user selects their four iron and provides intent for a slice, thegrip app106 will analyze the historic shot metrics based on the current ball lie data to determine a hand grip for the four iron that produces a slice for the current ball lie and distance to green.
• According to aspects of the invention, the database is populated with data from the user's historic (past) golf shots. In embodiments thegrip app106 is configured with a learning mode for capturing the user's historic shot data. When the user performs a shot in the learning mode, thegrip app106 first obtains the ball starting location (e.g., GPS location), ball lie angle (e.g., flat lie, uphill lie, downhill lie, side hill lie), and ball lie surface (e.g., fairway, rough, sand) in one of the manners described herein (e.g., automated, manual, hybrid). This data is saved in a database entry for this golf shot.
• Thegrip app106 determines the golf club being used for the current shot. In an automated embodiment, thegrip app106 uses data from the accelerometers of all thesmart grips70 to determine which club is moving and which clubs are stationary, and determines that the moving club is the club being used for the current shot. In a manual embodiment, the user may provide input to a user interface of theuser device100 to indicate which club is being used for the current shot. This data is saved in the database entry for this golf shot.
• Thegrip app106 also determines a grip position of the user's hands on the club for the current shot. In embodiments, theprocessor76 in thesmart grip70 of the club being used receives data from thepressure sensors82 in thesmart grip70 and transmits data to theuser device100. The pressure sensor data (and the defined location of each respective pressure sensor82) is used by thegrip app106 to determine a grip position of the user's hands on thesmart grip70. This data is saved in the database entry for this golf shot.
• Still referring to the learning mode, when the user swings the club for the current golf shot, the data from theaccelerometer86 may be transmitted to theuser device100 and used by thegrip app106 to determine a strength of swing (e.g., half swing or full swing) and an amount of divot for the shot (e.g., no divot, small divot, large divot). Alternatively, the user may provide input, via a user interface on theuser device100, that defines the strength of swing and amount of divot. This data is saved in the database entry for this golf shot.
• Still referring to the learning mode, thegrip app106 determines a distance, direction (e.g., straight, slice, hook), and loft (e.g., low, medium, high) for the current shot. These may be determined in automated or manual fashion. In a manual embodiment, the user inputs data via a user interface on theuser device100, the user input defining the distance, direction, and loft for the current shot. In an automated embodiment, the distance may be determined from the GPS starting location and GPS ending location of the ball for the current shot. The GPS starting location and the GPS ending location may be determined by theuser device100 since theuser device100 is with the user at the starting location and is also is with the user when the user travels to their ball after the shot, i.e., at the ending location. The golf ball may also be equipped with a GPS sensor and an accelerometer that communicate with theuser device100 to provide data that can be used to determine distance, direction, and loft. Starting and ending location can also be input by the user via themap app108, e.g., by the user touching a display of a map of the golf course to indicate the locations. The distance, direction, and loft data is saved in the database entry for this golf shot.
• In embodiments, when there is an insufficient amount of data in the database to provide a recommendation for an optimal club and grip, thegrip app106 may determine an optimal club and grip using data associated with the user. For example, thegrip app106 may use the user's height and length of the user's golf club to calculate a grip position for the club.
• FIGS. 5-7 depict exemplary methods in accordance with aspects of the invention. The steps of the methods may be performed in the system ofFIG. 2 and are described with reference to the elements and steps described with respect toFIG. 2.

As described with respect toFIG. 2, theprocessor76 of thesmart grip70 of the club being swung receives data from the array ofpressure sensors82 in thesmart grip70 and transmits this data to thegrip app106 on theuser device100. Thegrip app106 can use the data from each of thepressure sensors82 and the pre-defined location of each of thepressure sensors82 in thesmart grip70 to determine a grip position of the user during the swing of the golf club.
• Atstep505, the system determines results of the golf shot. The results may include at least one of distance of ball travel, direction of ball travel (e.g., straight, slice, hook), and loft of ball travel (e.g., low, medium, high) for the golf shot. The results may also include one or more of swing speed and amount of divot for the golf shot. This data may be determined in the manner described with respect toFIG. 2, e.g., in a manual or automated manner.
• Atstep506, the system stores the data for this swing (e.g., the data obtained at steps502-505) as an entry in thedatabase110. In this manner, the database is populated with an entry for this swing, and this entry may be used in a subsequent determination of an optimal club and grip for a golf shot for this user.
• The steps of the method ofFIG. 5 may be repeated many times at a practice facility (e.g., a driving range) to accumulate a large amount of historic shot data in the database. The steps of the method ofFIG. 5 may also be used during gameplay on a golf course. For example, every shot taken by the user on the golf course can be saved as an entry in the database.

For example, the user may provide the intent input via a user interface of theuser device100 or via an input mechanism integrated into thesmart grip70. The intent may be, for example, one of: slice, hook, low loft, and high loft.
• Atstep604, the system determines the ball lie data, e.g., ball location, distance to the green, ball lie angle, and ball lie surface. This data may be determined in the manner described with respect toFIG. 2, e.g., automatically by the system or manually via user input.
• Atstep605, the system determines an optimal grip position for the user-selected club. Step605 may be performed in the manner described with respect toFIG. 2, e.g., based on the ball lie data, the user-selected club, the user intent, and the database of the user's historic shot metrics. Step605 includes determining a grip position for the user-selected club and current ball lie that, based on historical shot results for this user, will achieve the desired intent.

Step607 may be performed in the manner described with respect toFIG. 2 and as depicted in the examples ofFIGS. 3 and 4.
• Atstep608, theprocessor76 receives data from thepressure sensors82 of thesmart grip70 and determines whether the user has placed their hands in locations that correspond to the determined optimal grip position. In the event that the user has not placed their hands in locations that correspond to the determined optimal grip position, then the system generates a warning, such as a vibration or audible tone generated by theuser device100 and/or activating other ones of theindicators84 of the smart grip, e.g., in a blinking or all-on manner. Following the warning, the process returns to step607 where thesmart grip70 again activates a subset of theindicators84 based on the data that defines the determined optimal grip position.
