[0001] The present invention relates to a technique for providing advice to golfers. [Background technology]

[0002] Systems have been proposed to improve a golfer's swing and to recommend golf clubs or golf balls suitable for the golfer (for example, Patent Documents 1 to 13). Such systems measure the impact of a golf ball by a golfer and provide advice to the golfer using the measurement results. As a measure of the impact, it has been proposed to measure the golfer's swing motion and the behavior of the hit ball. With such measurement technology, it is possible to estimate the carry (flight distance) and run (rolling distance) of the hit ball. [Prior art documents] [Patent documents]

[0004] The trajectory and distance of the ball that a golfer expects when hitting the ball differs depending on the golfer's preferences and the situation of the shot. For example, in the case of a control shot or an approach shot, some golfers aim for a trajectory with little run by dropping the golf ball close to the pin, while other golfers aim for a trajectory with the golf ball dropping a little away from the pin and rolling to some extent to approach the pin. The distance that a golfer expects to hit the ball differs depending on the trajectory. Conventional technology has room for improvement in terms of providing advice that reflects the golfer's aims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the invention according to the claims, and not all combinations of features described in the embodiments are essential to the invention. Two or more features among the multiple features described in the embodiments may be arbitrarily combined. In addition, the same reference numbers are used for the same or similar configurations, and duplicated descriptions are omitted.

[0010] First Embodiment <System configuration> 1 is a schematic diagram of an information processing system 1 according to one embodiment of the present invention. System 1 includes a measurement device 2 and an information processing device 3. Arrows X, Y, and Z indicate a three-dimensional coordinate system at the bat, with arrows X and Y indicating horizontal directions that are perpendicular to each other, and arrow Z indicating the vertical direction. Arrow X is set in the direction of the flight line of the golf ball.

[0011] The measurement device 2 is a device that measures the impact of the golfer 100 with the golf ball 102. In this embodiment, the measurement target is the behavior of the golf ball 102, and the measurement device 2 is a trajectory measurement device for the golf ball 102. For example, a TRACKMAN made by TRACKMAN Inc. can be used as the trajectory measurement device. Note that the measurement target may be the swing motion of the golfer 100 or the behavior of the golf club 101, as long as it is possible to generate measured trajectory information, which will be described later.

[0012] The information processing device 3 includes a calculation device 30, a display device 34, and an input device 35. A personal computer or a tablet can be used as the information processing device 3. The calculation device 30 includes a processing unit 31, a storage unit 32, and an I / F unit (interface unit) 33, which are electrically connected to each other. The processing unit 31 is a processor such as a CPU. The processing unit 31 may be composed of multiple processors. The storage unit 32 includes one or multiple storage devices. The storage device is, for example, a RAM, a ROM, a hard disk, etc. The storage unit 32 stores a program executed by the processing unit 31 and various data. The program executed by the processing unit 31 can be composed of multiple instructions that can be read by the processing unit 31.

[0013] The I / F unit 33 inputs and outputs data between an external device and the processing unit 31. The I / F unit 33 includes, for example, an I / O interface and a communication interface. The measurement device 2 and the calculation device 30 are connected so as to be able to communicate with each other, and the measurement results of the measurement device 2 are acquired by the calculation device 30.

[0014] A display device 34 and an input device 35 are connected to the arithmetic device 30. The display device 34 is, for example, an electronic image display device such as a liquid crystal display device, and displays the processing results of the arithmetic device 30. The input device 35 is, for example, a mouse or a keyboard, and accepts data input and operation instructions for the arithmetic device 30. The display device 34 and the input device 35 may be a touch panel that is integrally provided with them.

[0015] <Information related to advice> In this embodiment, advice is provided to the golfer 100 based on the measurement results of the hit by the golfer 100. A plurality of pieces of information related to advice that affect the trajectory and flight distance of the hit ball are stored in the memory unit 32. Figures 2(A) to 2(D) show an example.

[0016] FIG. 2(A) shows an example of ball information, which is information on a golf ball. In the example of FIG. 2(A), information on three types of golf balls B1 to B3 is shown. The ball information includes information on the characteristics and specifications of each of the balls B1 to B3. "Characteristics" include the amount of spin and the launch angle. These indicate the properties of each ball when the hitting conditions are the same. Ball B2 has intermediate characteristics, and is used as the standard for convenience. Ball B1 tends to have a higher spin rate and a smaller launch angle than ball B2. Conversely, ball B3 tends to have a lower spin rate and a larger launch angle than ball B2.

[0017] "Specifications" indicates the structural features of each ball, and in particular, indicates the structural features that affect the "characteristics." Ball B1 has a softer cover hardness and a harder core hardness than ball B2. The cover hardness is the hardness of the material of the outermost layer of the ball, and the core hardness is the hardness of the core material of the ball. Ball B3 has a harder cover hardness and a softer core hardness than ball B2.

[0018] FIG. 2(B) shows an example of club information, which is information on golf clubs. In the example of FIG. 2(B), information on three types of clubs C1 to C3 is shown. In this embodiment, each of the clubs C1 to C3 is assumed to be an iron club set (for example, a 5-iron to a wedge). The club information includes information on the characteristics and specifications of each of the clubs C1 to C3. "Characteristics" includes the amount of spin and the launch angle. These indicate the properties of each club when the hitting conditions are the same. Club C2 has intermediate characteristics, and is used as the standard for convenience. Club C1 tends to have a higher spin rate than club C2, and also tends to have a smaller launch angle. Conversely, club C3 tends to have a lower spin rate than club C2, and also tends to have a larger launch angle.

[0019] "Specifications" indicates the structural features of each club, and in particular, indicates the structural features that affect the "characteristics." When comparing clubs of the same number, Club C1 has a higher center of gravity and a smaller loft angle than Club C2. When comparing clubs of the same number, Club C3 has a lower center of gravity and a larger loft angle than Club C2.

[0020] Figures 2(C) and 2(D) show examples of technical information related to golf playing techniques. Six types of information T1-T3 and T11-T13 are shown in Figures 2(C) and 2(D). The technical information includes information on contents and effects. Information T1-T3 is information that mainly affects the trajectory, and information T11-T13 is information that mainly affects the flight distance.

[0021] In the technical information in Figure 2(C), "content" includes "management" and "swing." "Management" is information about how to attack the golf course, and "swing" is information about the swing motion (how to hit the ball). "Effect" indicates the effect obtained by practicing the "swing."

[0022] The "management" information in T1 teaches how to increase the carry of the ball when aiming at the pin. The "swing" information teaches how to strike the golf ball from a higher position with the golf club head. The corresponding "effects" include an increase in the amount of spin and a decrease in the launch angle.

[0023] Information T2 recommends that the golfer 100 maintain the status quo. Information T3, "Management," teaches the golfer 100 to increase the run of the ball when aiming for the pin (to make the ball land further away from the pin). "Swing" teaches the golfer to strike the golf ball as if sweeping it. The corresponding "Effects" include a reduction in the amount of spin and an increase in launch angle.

[0024] In the technical information of FIG. 2(D), the "content" includes distance recognition. Distance recognition is the relationship between the target distance of the golfer 100 and the type of club used. The "distance recognition" of information T11 teaches the golfer to increase the club number for the target distance. For example, it is recommended that the golfer 100 who hits the ball 150 yards with a 7 iron should hit the ball with a 6 iron. The corresponding "effect" is an increase in the distance. Information T12 recommends the golfer 100 to maintain the current state. The "distance recognition" of information T13 teaches the golfer to decrease the club number for the target distance. For example, it is recommended that the golfer 100 who hits the ball 150 yards with a 7 iron should hit the ball with an 8 iron. The corresponding "effect" is a decrease in the distance.

[0025] <Processing example> An example of a processing program executed by the arithmetic unit 30 of the information processing device 3 will be described with reference to Fig. 3(A). The figure is a flow chart showing an example of advice providing processing executed by the processing unit 31.

[0026] The trajectory and distance of the ball that the golfer 100 assumes when hitting the ball differs depending on the golfer's 100 preferences and the situation of the hit. In particular, in the case of a control shot or an approach shot, some golfers aim for a trajectory with little run by dropping the golf ball near the pin, while others aim for a trajectory where the golf ball drops a little away from the pin and rolls to some extent to approach the pin. In this embodiment, the trajectory (assumed trajectory) and distance (assumed distance) of the golf ball 102 intended by the golfer 100 before hitting the ball are compared with the trajectory (measured trajectory) and distance (measured distance) of the golf ball 102 measured by the measuring device 2, and advice is given to bring the actual trajectory and distance closer to the trajectory and distance intended by the golfer 100.

[0027] In S1, expected information is acquired. The expected information includes expected trajectory information indicating an expected trajectory and expected flight distance information indicating an expected flight distance. FIG. 3(B) is a flowchart showing an example of the acquisition process in S1. In this embodiment, options for the expected trajectory are presented to the golfer 100, and the option selected by the golfer 100 is acquired as the expected trajectory information. As for the expected flight distance, the distance input by the golfer 100 is acquired as the expected flight distance information. In S11, a selection screen showing options for the expected trajectory and an input screen for the expected flight distance are displayed on the display device 34.

[0028] FIG. 4 is an explanatory diagram showing an example of options for the expected trajectory. In the illustrated example, a situation is assumed in which a golfer 100 hits a golf ball 102 from a hitting position that is a distance Li0 away from the pin 111 to aim at the pin 111. The distance Li0 is, for example, 50 to 150 yards. Two types of options for the expected trajectory, expected trajectory Ti1 and expected trajectory Ti2, are shown in the figure. Both expected trajectories Ti1 and Ti2 are defined by a launch angle θi, a carry (distance from the hitting position to the first landing point) Li1, and a run (distance from the first landing point to the stopping position) Li2 (Li1+Li2=Li0). Comparing the expected trajectories Ti1 and Ti2, the launch angle θi is larger in the expected trajectory Ti1, the carry Li1 is longer in the expected trajectory Ti2, and the run Li2 is longer in the expected trajectory Ti1.

[0029] The expected trajectory Ti1 is a trajectory that reduces the amount of spin of the golf ball 102, causing the golf ball 102 to land on the green 110 at a position away from the pin 111, and rolls closer to the pin 111. The expected trajectory Ti2 is a trajectory that increases the amount of spin of the golf ball 102, causing the golf ball 102 to land on the green 110 at a position closer to the pin 111, and rolls less to get closer to the pin 111. The golfer 100 selects the trajectory that is closest to his or her intention from the two expected trajectories Ti1 and Ti2.

[0030] The expected flight distance is the total distance of the carry and the run, but may be the distance of only the carry.

[0031] Returning to FIG. 3(B), in S11, the expected trajectory Ti1 and the expected trajectory Ti2 are displayed on the display device 34, and a numerical input screen for the expected flight distance is displayed on the display device 34. In S12, the selection and input of the expected trajectory and the expected flight distance by the golfer 100 is accepted. The selection and input can be performed by the golfer 100 or the operator via the input device 35. In S13, the expected information is confirmed. The confirmed expected information includes expected trajectory information indicating the expected trajectory selected in S12 and expected flight distance information indicating the flight distance input in S12. In this embodiment, both the expected trajectory information and the expected flight distance information are numerical information, and the expected trajectory information is the ratio of the carry to the run of the expected trajectory selected by the golfer 100 (Li2 / Li1).

[0032] Returning to FIG. 3(A), in S2, the golfer 100 actually hits the golf ball 102 with the golf club 101, and this hit (the behavior of the golf ball 102) is measured by the measurement device 2. The golf ball 102 used for the hit is the ball B2 in FIG. 2(A), and the club is one of the clubs C2 in FIG. 2(B) (e.g., a wedge or a 7-iron). The measurement device 2 measures or estimates the trajectory and flight distance of the hit ball. From the measurement results of the measurement device 2, the trajectory Tr, launch angle θr, carry Lr1, run Lr2, and flight distance Lr0 of the hit ball are measured. In this embodiment, the expected flight distance is the total distance of the carry and run, so that the flight distance Lr0 is Lr0=Lr1+Lr2 correspondingly. However, if the expected flight distance is the distance of only the carry, the flight distance Lr0 is Lr0=Lr1. The impact may be measured multiple times, and the measurement result used may be an average value of the multiple results.

[0033] Returning to FIG. 3(A), in S3, measurement information is generated from the measurement results of the measurement device 2 in S2. The measurement information includes measured trajectory information and measured flight distance information. The measured trajectory information is numerical information corresponding to the expected flight distance information, and is the ratio of the carry to the run (Lr2 / Lr1). The measured flight distance information is also numerical information corresponding to the expected flight distance information, and is the total distance of the carry and the run.

[0034] In S4, the expected trajectory information obtained in S1 is compared with the measured trajectory information generated in S3, and the expected flight distance information obtained in S1 is compared with the measured flight distance information generated in S3. At least one piece of advice that reduces the discrepancy between the two is selected from the advice information stored in the memory unit 32 as advice to be provided to the golfer 100.

[0035] Fig. 6 is an explanatory diagram showing an example of a selection method. In the example shown in the figure, a recommended ball (one of B1 to B3) and technical information (one of T11 to T13) are selected as advice based on an evaluation value Et (=Lr2 / Lr1-Li2 / Li1) calculated from expected trajectory information and measured trajectory information, and an evaluation value Ed (=Lr0-Li0) calculated from expected flight distance information and measured flight distance information. In the example shown in Fig. 6, a coordinate system with the evaluation value Et on the vertical axis and the evaluation value Ed on the horizontal axis is divided into areas corresponding to the recommended balls B1 to B3 and the technical information T11 to T13, and the recommended ball and technical information are selected.

[0036] When the evaluation value Et is close to 0, it means that the expected trajectory and the measured trajectory are close to each other. When the evaluation value Ed is close to 0, it means that the expected flight distance and the measured flight distance are close to each other. In a region where the evaluation value Et is close to 0 and the evaluation value Ed is close to 0, such as when the coordinates of the evaluation values ​​Et and Ed are point P3, the ball B2 used for the hit is selected as the recommended ball, and T12 (as is) is selected as the technical information.

[0037] The larger the positive evaluation value Et is, the greater the proportion of run distance in the measured trajectory compared to the expected trajectory. In the example of FIG. 4, this means that the golfer 100 intended to hit the expected trajectory Ti2, but the measured trajectory was closer to the expected trajectory Ti1. In order to bring the measured trajectory closer to the expected trajectory, it is effective to increase the spin rate of the hit ball. As advice, ball B1, which has a higher spin rate than golf ball B2 used for the hit, is selected as the recommended ball.

[0038] When the evaluation value Et is a positive value (+), the larger the evaluation value Ed is a positive value (+), the longer the measured distance is compared to the expected distance. Therefore, advice to reduce the distance is considered, but if the golfer 100 uses ball B1, which has a higher spin rate, instead of ball B2, it is expected that the measured distance will be shorter than the expected distance with the same force. Therefore, in the region where the evaluation value Et is a positive value and the evaluation value Ed is also a positive value, such as when the coordinates of the evaluation values ​​Et and Ed are point P1, the ball B2 used for the hit is selected as the recommended ball, and T12 (as is) is selected as the technical information.

[0039] When the evaluation value Et is a positive value (+), the larger the evaluation value Ed is a negative value (-), the shorter the measured distance is compared to the expected distance. Therefore, advice to increase the distance can be considered. Although advice to increase the distance can be to change the strength of the swing, it is relatively easy to have the golfer 100 reconsider the relationship between the distance and the club number. Therefore, in the region where the evaluation value Et and the evaluation value Ed are positive and negative, such as when the coordinates of the evaluation value Et and the evaluation value Ed are point P4, ball B1 is selected as the recommended ball, and T11 (increase the club number) is selected as the technical information.

[0040] The larger the negative evaluation value Et is, the greater the proportion of the measured trajectory in the carry distance compared to the expected trajectory. In the example of FIG. 4, this means that the golfer 100 intended to hit the expected trajectory Ti1, but the measured trajectory was closer to the expected trajectory Ti2. In order to bring the measured trajectory closer to the expected trajectory, it is effective to reduce the amount of spin of the hit ball. As advice, ball B3, which has a lower amount of spin than golf ball B2 used for the hit, is selected as the recommended ball.

[0041] When the evaluation value Et is a negative value (-), the larger the evaluation value Ed is a positive value (+), the longer the measured distance is compared to the expected distance. Therefore, advice to reduce the distance can be considered. Although advice to reduce the distance can be given by changing the strength of the swing, it is relatively easy to have the golfer 100 reconsider the relationship between the distance and the club number. Therefore, in a region where the evaluation value Et and the evaluation value Ed have negative values ​​and the evaluation value Ed have positive values, such as when the coordinates of the evaluation values ​​Et and Ed are point P5, ball B3 is selected as the recommended ball, and T13 (lower the club number) is selected as the technical information.

[0042] When the evaluation value Et is a negative value (-), the larger the evaluation value Ed is, the shorter the measured distance is than the expected distance. Therefore, advice to increase the distance is considered, but if the golfer 100 uses ball B3, which has a lower spin rate, instead of ball B2, it is expected that the measured distance will be longer than the expected distance with the same force. Therefore, in the region where the evaluation value Et is a negative value and the evaluation value Ed is also a negative value, such as when the coordinates of the evaluation values ​​Et and Ed are point P2, ball B3 is selected as the recommended ball, and T12 (as is) is selected as the technical information.

[0043] The golfer 100 can improve his / her shot by appropriately adopting the selected advice.

[0044] The same applies to the selection of a recommended club from the clubs C1 to C3 as advice, and the selection of technical information from the technical information T1 to T3. Fig. 7(A) is an explanatory diagram of a selection method for selecting a recommended club (one of C1 to C3) and technical information (one of T11 to T13) as advice, and Fig. 7(B) is an explanatory diagram of a selection method for selecting technical information (one of T1 to T3) and technical information (one of T11 to T13) as advice.

[0045] The concept of either selection method is the same as that of Fig. 6. That is, in a region where the evaluation value Et is close to 0 and the evaluation value Ed is close to 0, such as when the coordinates of the evaluation values ​​Et and Ed are point P3, the club C2 used for the shot is selected as the recommended club, T2 (as is) is selected as the technical information, and T12 (as is) is selected as the technical information.

[0046] In a region where the evaluation value Et and the evaluation value Ed are positive, such as when the coordinates of the evaluation values ​​Et and Ed are point P1, the club C2 used for the hit is selected as the recommended club, T2 (as is) is selected as the technical information, and T12 (as is) is selected as the technical information. In a region where the evaluation value Et and the evaluation value Ed are positive, such as when the coordinates of the evaluation values ​​Et and Ed are point P4, the club C1 which increases the amount of spin is selected as the recommended club, T1 (increase the carry and hit the ball from above) is selected as the technical information, and T11 (increase the club number) is selected as the technical information.

[0047] When the coordinates of the evaluation values ​​Et and Ed are at point P5, and the evaluation value Et is a negative value and the evaluation value Ed is a positive value, the club C3 that reduces the spin amount is selected as the recommended club, and T3 (increase the run and hit the ball as if sweeping it) is selected as the technical information, and T13 (lower the club number) is selected as the technical information. When the coordinates of the evaluation values ​​Et and Ed are at point P2, and the evaluation value Et is a negative value and the evaluation value Ed is also a negative value, the club C3 that reduces the spin amount is selected as the recommended club, and T3 (increase the run and hit the ball as if sweeping it) is selected as the technical information, and T12 (as is) is selected as the technical information.

[0048] Second Embodiment The trajectory assumed by the golfer 100 may change depending on the speed of the green 110. It may be possible to set conditions related to the rolling of the golf ball 102 on the green 110. Fig. 8 is a flowchart showing an example of the advice providing process in this embodiment, which is an alternative process to Fig. 3(A).

[0049] In S1', settings of conditions related to the rolling of the golf ball 102 on the green 110 are accepted. These conditions may be three levels such as fast, normal, and slow, or may be values ​​(feet) on a stimpmeter. The conditions can be input by the golfer 100 or an operator using the input device 35.

[0050] The processes of S1 and S2 following S1' are the same as those of S1 and S2 in FIG. 3(A). In S3', the run distance Lr2 of the measurement result of the hit by the measurement device 2 is adjusted according to the conditions set in S1'. For example, if "fast" is set in S1', the distance Lr2 is multiplied by 1.3, and if "slow" is set, the distance Lr2 is multiplied by 0.8. Also, for example, if the value of the stimpmeter can be set in S1', the adjusted distance Lr2 can be calculated as the measured distance Lr2 × the set value ÷ the reference value. The reference value can be, for example, 10.0 feet. Then, the measured trajectory information is generated based on the adjusted distance Lr2.

[0051] The processes of S4 and S5 following S3' are the same as S4 and S5 in Fig. 3(A). According to this embodiment, advice corresponding to the green speed of the golf course used by the golfer 100 can be provided to the golfer 100.

[0052] <Third embodiment> In the first embodiment, the expected trajectory information and the measured trajectory information are the ratio of the carry distance to the run distance, but the run distance may be used. If the golfer 100 is an advanced player, the run distance may be used to intuitively predict the trajectory. In this case, in the process of S1 in FIG. 3(A), the golfer 100 specifies the run distance as a numerical value, and this is used as the expected trajectory information. Instead of a numerical value, one of multiple levels such as long, normal, and short may be specified, and in this case, the system may determine the run distance for each of the long, normal, and short run distances. FIG. 9(A) is an explanatory diagram showing an example of a method for selecting advice.

[0053] In the example shown, an evaluation value Et (=Lr2-Li2) calculated from expected trajectory information and measured trajectory information, and an evaluation value Ed (=Lr0-Li0) calculated from expected flight distance information and measured flight distance information are used as criteria, and a recommended ball (one of B1-B3) and technical information (one of T11-T13) are selected as advice. The selection concept is the same as in the example of FIG. 6. In an area where the evaluation value Et is close to 0 and the evaluation value Ed is close to 0, the ball B2 used for the hit is selected as the recommended ball, and T12 (as is) is selected as the technical information.

[0054] The larger the evaluation value Et is in a positive value (+), the longer the run distance of the measured trajectory is compared to the expected trajectory. In the example of FIG. 4, the golfer 100 intended the expected trajectory Ti2, but the measured trajectory was closer to the expected trajectory Ti1. In order to make the measured trajectory closer to the expected trajectory, it is effective to increase the amount of spin of the hit ball. In a region where the evaluation value Et is a positive value and the evaluation value Ed is also a positive value, the ball B2 used for the hit is selected as the recommended ball, and T12 (as is) is selected as the technical information. In a region where the evaluation value Et is a positive value and the evaluation value Ed is a negative value, the ball B1 is selected as the recommended ball, and T11 (raise the club number) is selected as the technical information.

[0055] The larger the evaluation value Et is in the negative value (-), the shorter the run distance of the measured trajectory is compared to the expected trajectory. In the example of FIG. 4, the golfer 100 intended to hit the expected trajectory Ti1, but the measured trajectory was closer to the expected trajectory Ti2. In order to make the measured trajectory closer to the expected trajectory, it is effective to reduce the amount of spin of the hit ball. In a region where the evaluation value Et is a negative value and the evaluation value Ed is a positive value, ball B3 is selected as the recommended ball, and T13 (lower the club number) is selected as the technical information. In a region where the evaluation value Et is a negative value and the evaluation value Ed is also a negative value, ball B3 is selected as the recommended ball, and T12 (as is) is selected as the technical information.

[0056] Next, the expected trajectory information and the measured trajectory information may be the launch angle of the ball. When the golfer 100 is an advanced player, the launch angle may be used to intuitively predict the trajectory. In this case, in the process of S1 in FIG. 3(A), the golfer 100 specifies the launch angle as a numerical value, which is used as the expected trajectory information. Instead of a numerical value, one of multiple levels such as large, normal, and small may be specified. In this case, the system determines the run distance as long, normal, or short, based on the premise that a large launch angle results in a low spin rate and a long run distance, and a small launch angle results in a high spin rate and a short run distance. FIG. 9(B) is an explanatory diagram showing an example of a method for selecting advice.

[0057] In the example shown in the figure, an evaluation value E (=θr-θi) calculated from expected trajectory information and measured trajectory information, and an evaluation value Ed (=Lr0-Li0) calculated from expected flight distance information and measured flight distance information are used as criteria, and a recommended ball (one of B1 to B3) and technical information (one of T11 to T13) are selected as advice. The selection concept is the same as in the example of FIG. 6. In an area where the evaluation value Et is close to 0 and the evaluation value Ed is close to 0, the ball B2 used for the hit is selected as the recommended ball, and T12 (as is) is selected as the technical information.

[0058] The larger the positive value (+) of the evaluation value Et, the greater the launch angle of the measured trajectory compared to the expected trajectory. In the example of FIG. 4, this means that the golfer 100 intended the expected trajectory Ti2, but the measured trajectory was closer to the expected trajectory Ti1. In order to make the measured trajectory closer to the expected trajectory, it is necessary to reduce the launch angle. In a region where the evaluation value Et is a positive value and the evaluation value Ed is also a positive value, the ball B2 used for the hit is selected as the recommended ball, and T12 (as is) is selected as the technical information. In a region where the evaluation value Et is a positive value and the evaluation value Ed is a negative value, the ball B1 is selected as the recommended ball, and T11 (raise the club number) is selected as the technical information.

[0059] The larger the negative evaluation value Et is, the smaller the launch angle of the measured trajectory is compared to the expected trajectory. In the example of FIG. 4, this means that the golfer 100 intended the expected trajectory Ti1, but the measured trajectory was closer to the expected trajectory Ti2. In order to make the measured trajectory closer to the expected trajectory, it is necessary to increase the launch angle of the ball. In a region where the evaluation value Et is a negative value and the evaluation value Ed is a positive value, ball B3 is selected as the recommended ball, and T13 (lower the club number) is selected as the technical information. In a region where the evaluation value Et is a negative value and the evaluation value Ed is also a negative value, ball B3 is selected as the recommended ball, and T12 (as is) is selected as the technical information.

[0060] The same applies to the selection of a recommended club from among the clubs C1 to C3 as advice, or the selection of technical information from the technical information T1 to T3. In Figures 9(A) and 9(B), by replacing B1 to B3 with C1 to C3 or T1 to T3, it is possible to select the clubs C to C3 or the technical information T1 to T3.

[0061] <Fourth embodiment> In the first embodiment, there are three types of recommended balls (B1 to B3), recommended clubs (C1 to C3), and technical information (T1 to T3), but there may be two types, four or more types, or the number of types may be different. The size of each selection area of ​​the coordinate system may also be different from each other.

[0062] <Fifth embodiment> In the first embodiment, in the impact measurement in S2 of FIG. 3(A), the impact with one of the clubs C2 is measured and advice is selected, but impacts with multiple clubs with different numbers may be measured and advice may be selected. For example, impacts with the 7 iron and wedge of the clubs C2 may be measured, each measured trajectory information may be generated (S3), and advice may be selected (S4). While the expected distance is specified for each club, the expected trajectory may be common to each club, or may be specified by the golfer 100 for each club. Through the golf club set, the trajectory at the time of impact can be made closer to the trajectory expected by the golfer 100.

[0063] FIG. 10(A) shows an example of a method of selecting advice (recommended ball) when a shot is measured with two types of clubs 1 and 2 with different numbers. In the example shown, a coordinate system with the evaluation value Et1 of club 1 as the vertical axis and the evaluation value Et2 of club 2 as the horizontal axis is divided into areas corresponding to recommended balls B1 to B3 and X to select a recommended ball. The evaluation values ​​Et1 and Et2 correspond to the evaluation value Et in the above embodiment, and may be the difference in the ratio of carry and run between the expected trajectory information and each measured trajectory information described in the first embodiment, or may be the difference in run distance or the difference in launch angle described in the third embodiment. The evaluation values ​​Et1 and Et2 may be weighted depending on the club number.

[0064] In the region where the evaluation value Et1 of club 1 and the evaluation value Et2 of club 2 are both close to 0, the ball B2 used for the hit is selected as the recommended ball. Although not shown, the evaluation value Ed of the flight distance is, for example, the average value of club 1 and club 2. If the average value is within a predetermined range close to 0, technical information T12 (as is) is selected, if the average value is a positive value (+) beyond the predetermined range, technical information T13 (lower the club number) is selected, and if the average value is a negative value (-) beyond the predetermined range, technical information T11 (increase the club number) is selected.

[0065] Next, when the evaluation value Et1 of club 1 is a positive value (+) and the evaluation value Et2 of club 2 is also a positive value (+), the run distance tends to be longer than the expected trajectory for both clubs 1 and 2. As the recommended ball, ball B1, which has a higher spin rate than ball B2 used for the hit, is selected. Although not shown, the evaluation value Ed of the flight distance is set to, for example, the average value of clubs 1 and 2. When the average value is within a predetermined range close to 0 or exceeds the predetermined range and is a positive value (+), technical information T13 (as is) is selected in anticipation of a decrease in flight distance due to the use of ball B1, and when the average value is a negative value (-) outside the predetermined range, technical information T11 (raise the club number) is selected.

[0066] Next, when the evaluation value Et1 of club 1 is a negative value (-) and the evaluation value Et2 of club 2 is also a negative value (-), the run distance tends to be short for the expected trajectory for both clubs 1 and 2. As the recommended ball, ball B3, which has a lower spin rate than ball B2 used for the hit, is selected. Although not shown, the evaluation value Ed of the flight distance is set to, for example, the average value of clubs 1 and 2. When the average value is within a predetermined range close to 0 or exceeds the predetermined range and is a positive value (+), technical information T13 (lowering the club number) is selected in anticipation of an increase in flight distance due to the use of ball B1, and when the average value is a negative value (-) below the predetermined range, technical information T12 (as is) is selected.

[0067] When the evaluation values ​​Et1 and Et2 belong to region X, it means that the expected trajectory and the measured trajectory show opposite trends in the hits with club 1 and club 2. In this case, a recommended ball is selected using the selection method of FIG. 10(B) based on the relationship between the expected flight distance and the measured flight distance.

[0068] In the illustrated example, a coordinate system with the evaluation value Ed1 of club 1 on the vertical axis and the evaluation value Ed2 of club 2 on the horizontal axis is divided into areas corresponding to recommended balls B1 to B3 and Y, and a recommended ball is selected. The evaluation values ​​Ed1 and Ed2 correspond to the evaluation value Ed in the above embodiment.

[0069] The ball B2 used for the hit is selected as the recommended ball in the region where the evaluation value Ed1 of club 1 and the evaluation value Ed2 of club 2 are both close to 0. In this embodiment, no selection of the technical information T11 to T13 is made.

[0070] When the evaluation value Ed1 of club 1 is a positive value (+) and the evaluation value Ed2 of club 2 is also a positive value (+), the measured flight distance tends to be longer than the expected flight distance for both clubs 1 and 2. Ball B1, which has a higher spin rate than ball B2 used for the shot, is selected as the recommended ball. By using ball B1, golfer 100 can bring the actual flight distance closer to the expected flight distance.

[0071] When the evaluation value Ed1 of club 1 is a negative value (-) and the evaluation value Ed2 of club 2 is also a negative value (-), the measured flight distance tends to be shorter than the expected flight distance for both clubs 1 and 2. Ball B3, which has a lower spin rate than ball B2 used for the shot, is selected as the recommended ball. By using ball B3, golfer 100 can bring the actual flight distance closer to the expected flight distance.

[0072] When the evaluation values ​​Ed1 and Ed2 belong to region Y, there is a reverse trend between the expected flight distance and the measured flight distance in the hits with club 1 and club 2. In this case, the recommended ball is selected based on the evaluation value Ed of the club prioritized by the golfer 100 out of clubs 1 and 2.

[0073] For example, if the golfer 100 prioritizes the club 1, the recommended ball will be ball B1 if the value of Ed1 is a large positive value, and the recommended ball will be ball B3 if the value of Ed1 is a large negative value. If the value of Ed1 is close to 0, the recommended ball will be ball B1 or ball B2, or ball B3 or ball B2, and either both will be presented to the golfer 100, or one ball will be selected according to another rule. Similarly, if the golfer 100 prioritizes the club 2, the recommended ball will be ball B1 if the value of Ed2 is a large positive value, and the recommended ball will be ball B3 if the value of Ed2 is a large negative value. If the value of Ed2 is close to 0, the recommended ball will be ball B1 or ball B2, or ball B3 or ball B2, and either both will be presented to the golfer 100, or one ball will be selected according to another rule.

[0074] Although Fig. 10(A) and Fig. 10(B) show an example of selecting a recommended ball, the same applies to selecting a recommended club or technical information (T1 to T3).

[0075] Figures 11(A) and 11(B) are explanatory diagrams of a selection method for selecting a recommended club (one of C1 to C3) as advice, and Figures 12(A) and 12(B) are explanatory diagrams of a selection method for selecting technical information (one of T1 to T3) as advice. The evaluation values ​​and concepts in both cases are the same as those in the recommended ball selection method illustrated in Figures 10(A) and 10(B).

[0076] In the example of FIG. 11(A), similarly to the example of FIG. 10(A), a coordinate system having the evaluation value Et1 of club 1 on the vertical axis and the evaluation value Et2 of club 2 on the horizontal axis is divided into an area corresponding to recommended clubs C1 to C3 and X, thereby selecting a recommended club.

[0077] The club C2 used for hitting is selected as the recommended club in the region where the evaluation value Et1 of club 1 and the evaluation value Et2 of club 2 are both close to 0. The method of selecting the technical information T11 to T13 is the same as in the case of the recommended ball example.

[0078] Next, when the evaluation value Et1 of club 1 is a positive value (+) and the evaluation value Et2 of club 2 is also a positive value (+), the run distance tends to be long for the expected trajectory for both clubs 1 and 2, and the recommended club is selected as the club C1, which has a higher spin rate than the club C2 used for the shot. The method of selecting the technical information T11 to T13 is the same as in the case of the recommended ball example.

[0079] Next, when the evaluation value Et1 of club 1 is a negative value (-) and the evaluation value Et2 of club 2 is also a negative value (-), the run distance tends to be short for the expected trajectory for both clubs 1 and 2, and the recommended club is selected as club C3, which has a lower spin rate than club C2 used for the shot. The method of selecting technical information T11 to T13 is the same as in the case of the recommended ball example.

[0080] If the evaluation values ​​Et1 and Et2 belong to region X, a recommended ball is selected using the selection method of Fig. 11(B). In the example of Fig. 11(B), similar to the example of Fig. 10(B), a coordinate system with the evaluation value Ed1 of club 1 on the vertical axis and the evaluation value Ed2 of club 2 on the horizontal axis is divided into recommended clubs C1 to C3 and a region corresponding to Y to select a recommended ball.

[0081] In the region where the evaluation value Ed1 of club 1 and the evaluation value Ed2 of club 2 are both close to 0, the club C2 used for the shot is selected as the recommended club. No selection is made of the technical information T11 to T13.

[0082] When the evaluation value Ed1 of club 1 is a positive value (+) and the evaluation value Ed2 of club 2 is also a positive value (+), the measured distance tends to be longer than the expected distance for both clubs 1 and 2, and the recommended club is selected as club C1, which has a higher spin rate than club C2 used for the shot. By using club C1, the golfer 100 can bring the actual distance closer to the expected distance.

[0083] When the evaluation value Ed1 of club 1 is a negative value (-) and the evaluation value Ed2 of club 2 is also a negative value (-), the measured distance tends to be shorter than the expected distance for both clubs 1 and 2, and club C3, which has a lower spin rate than club C2 used for the shot, is selected as the recommended ball. By using club C3, the golfer 100 can bring the actual distance closer to the expected distance.

[0084] When the evaluation values ​​Ed1 and Ed2 belong to region Y, there is a tendency for the expected flight distance and the measured flight distance to be opposite to each other in the hits with club 1 and club 2. In this case, the recommended club is selected based on the evaluation value Ed of the club prioritized by the golfer 100 between club 1 and club 2. The selection method is the same as that for the recommended ball.

[0085] In the example of FIG. 12(A), similarly to the example of FIG. 10(A), a coordinate system with the evaluation value Et1 of club 1 on the vertical axis and the evaluation value Et2 of club 2 on the horizontal axis is divided into areas corresponding to technical information T1 to T3 and X, and one of the technical information T1 to T3 is selected.

[0086] The technical information T2 (as is) is selected in a region where the evaluation value Et1 of the club 1 and the evaluation value Et2 of the club 2 are both close to 0. The method of selecting the technical information T11 to T13 is the same as in the example of the recommended ball.

[0087] Next, when the evaluation value Et1 of club 1 is a positive value (+) and the evaluation value Et2 of club 2 is also a positive value (+), the run distance tends to be long for the expected trajectory for both clubs 1 and 2, and technical information T1 (increase the carry and hit the ball from above) is selected. The method of selecting technical information T11 to T13 is the same as in the case of the recommended ball example.

[0088] Next, when the evaluation value Et1 of club 1 is a negative value (-) and the evaluation value Et2 of club 2 is also a negative value (-), the run distance tends to be short for the expected trajectory for both clubs 1 and 2, and technical information T2 (increase the run and hit the ball as if sweeping it) is selected. The method of selecting technical information T11 to T13 is the same as in the case of the recommended ball example.

[0089] If the evaluation values ​​Et1 and Et2 belong to region X, one of the technical information T1 to T3 is selected using the selection method of Fig. 12(B). In the example of Fig. 12(B), similar to the example of Fig. 10(B), a coordinate system with the evaluation value Ed1 of club 1 on the vertical axis and the evaluation value Ed2 of club 2 on the horizontal axis is divided into regions corresponding to the technical information T1 to T3 and Y to select a recommended ball.

[0090] In a region where the evaluation value Ed1 of the club 1 and the evaluation value Ed2 of the club 2 are both close to 0, the technical information T2 (as is) is selected. The technical information T11 to T13 are not selected.

[0091] If the evaluation value Ed1 of club 1 is a positive value (+) and the evaluation value Ed2 of club 2 is also a positive value (+), the measured distance tends to be longer than the expected distance for both clubs 1 and 2, and technical information T1 (increase the carry and hit the ball from above) is selected.

[0092] When the evaluation value Ed1 of club 1 is a negative value (-) and the evaluation value Ed2 of club 2 is also a negative value (-), the measured distance tends to be shorter than the expected distance for both clubs 1 and 2, and technical information T2 (increase the run and hit the ball as if sweeping it) is selected.

[0093] When the evaluation values ​​Ed1 and Ed2 belong to region Y, there is a tendency for the expected flight distance and the measured flight distance to be opposite to each other in the hits with club 1 and club 2. In this case, one of the technical information T1 to T3 is selected based on the evaluation value Ed of the club prioritized by the golfer 100 between club 1 and club 2. The selection method is the same as for the recommended ball.

[0094] Sixth Embodiment Various modes can be adopted for the golfer 100 to specify the expected flight distance in S11 and S12 in Fig. 3(B). Fig. 13(A) and Fig. 13(B) show examples of the display screen of the display device 34 on which the golfer 100 can select the expected flight distance.

[0095] 13A shows an example of head speeds and corresponding distances assuming that the golfer 100 uses a driver. When the golfer 100 recognizes his / her own head speed, the expected distance is set by selecting the corresponding head speed.

[0096] 13B shows an example of head speed and corresponding distance assuming that the golfer 100 uses a No. 7 iron. If the golfer 100 is aware of his / her own head speed, the expected distance is set by selecting the corresponding head speed.

[0097] Seventh Embodiment Various modes may be adopted for the golfer 100 to specify the expected trajectory in S11 and S12 in Fig. 3(B). Fig. 14(A) shows an example of the display screen of the display device 34 when the golfer 100 selects the expected trajectory. In the example shown, an image of the area from the impact point HP to the pin 111 viewed from above is displayed, making it easy for the golfer 100 to grasp the position of the pin 111 on the green 110 when selecting the expected trajectory Ti1 or Ti2.

[0098] 14B shows an example of another display screen, in which the expected trajectories Ti1 and Ti2 are displayed in three dimensions. When the golfer 100 selects the expected trajectory Ti1 or Ti2, the launch angle and the height of the ball can be easily grasped.

[0099] 15(A) shows an example where the golfer 100 can arbitrarily specify an expected trajectory. The example shown is an example of an input screen where the golfer 100 can specify the landing point of the hit ball, and shows an example where a position on the green 110 is specified by the golfer 100. The expected trajectory information is specified by setting the distance from the hitting position HP to the position specified by the golfer 100 as the carry distance Li1, and the distance from the position specified by the golfer 100 to the pin 111 as the run distance Li2.

[0100] FIG. 15(B) also shows an example where the golfer 100 can arbitrarily specify an expected trajectory. The example shown is an example of an input screen where the golfer 100 can specify the position of the highest point of the ball. From the distance Li3 from the hitting position HP to the position specified by the golfer 100, the expected trajectory Ti is calculated according to a predetermined rule, and the carry distance Li1, run distance Li2, and launch angle θi are calculated. From these, the expected trajectory information is specified. Note that the golfer 100 may be able to specify the height in addition to the position of the highest point of the ball.

[0101] Eighth embodiment Various systems can be adopted instead of the system 1 illustrated in FIG. 1. The configuration example in FIG. 16 shows an example in which the information processing device 3 functions as a server on the network 110. The information processing device 3 includes a calculation device 30, but does not require the display device 34 and input device 35 in FIG. 1. The information processing device 3 can communicate with communication devices (such as a mobile terminal 201 and a personal computer 202) via a network 200. The network 200 is, for example, the Internet. The mobile terminal 201 and the personal computer 202 function as the display device 34 and the input device 35 in FIG. 1.

[0102] The measurement side configuration example EX1 includes a mobile terminal 201 and a measurement device 2A, and is a system suitable for a golfer 100 to personally measure a shot and receive advice. The measurement device 2A is a device attached to the shaft 101 (or grip) of the club 100, and includes an acceleration sensor and an angular velocity sensor. For example, the TSND121 from ATR-Promotions or the M-tracer from Seiko Epson can be used as the measurement device 2A.

[0103] The mobile terminal 201 is, for example, a smartphone, and has a short-range wireless communication function with the measuring device 2A. The measurement results of the measuring device 2A are transmitted to the mobile terminal 201. The mobile terminal 201 transmits the expected trajectory information specified by the golfer 100 and the measurement results to the information processing device 3. By receiving this information, the information processing device 3 executes the processes corresponding to S1 and S2 in FIG. 3(A). Then, the information processing device 3 executes the processes of S3 and S4, and transmits advice to the mobile terminal 201 as the process of S5. The received advice is displayed on the mobile terminal 201.

[0104] The measurement side configuration example EX2 includes a personal computer 202 and multiple measurement devices 2B, and is a system suitable for a golfer 100 to hit the ball and receive advice at a golf shop or the like. The measurement device 2B is a photographing device such as a video camera. The personal computer 202 has a function for processing images photographed by the photographing device 2B. The behavior of the ball at the time of hitting is photographed by the measurement device 2B. The photographed images are imported into the personal computer 202 and analyzed. The personal computer 202 transmits the expected trajectory information and the measurement results designated by the golfer 100 to the information processing device 3. By receiving this information, the information processing device 3 executes the processes corresponding to S1 and S2 in FIG. 3(A). Then, the information processing device 3 executes the processes of S3 and S4, and transmits advice to the personal computer 202 as the process of S5. The personal computer 202 displays the received advice.

[0105] Trajectory and distance can be estimated from the ball speed (initial speed), launch angle, and amount of backspin. When using the measurement device 2A, the ball speed (initial speed), launch angle, and amount of backspin can be obtained from the swing speed, face angle, head trajectory (hit angle), and impact point position (up, down, left, right) and an arithmetic formula obtained by performing correlation analysis or machine learning based on past data. The impact point position (up, down, left, right) may be identified by an operator by attaching pressure-sensitive paper to the face of the golf club and observing the trace of the golf ball.

[0106] <Other embodiments> The expected trajectory may be specified in a question and answer format for the golfer. For example, if the golfer answers "YES" to the question "Are you the type of person who tries to land the ball close to the pin without worrying about hitting it a little over when approaching?", a trajectory with less run may be set as the expected trajectory. Also, if the golfer answers "YES" to the question "Are you the type of person who wants to aim dead at the pin when approaching?", a trajectory with less run may be set as the expected trajectory. This makes it easier for beginners to specify the expected trajectory. Next, advice may be selected for each hitting situation. Examples of hitting situations include the slope of the hitting position (uphill, downhill, etc.) and the slope direction of the green.

[0107] Although the embodiment of the invention has been described above, the invention is not limited to the above embodiment, and various modifications and variations are possible within the scope of the gist of the invention. [Explanation of symbols]
