Golf error management support device and golf error management support program

Abstract

[Problem] To provide a golf error management support device and a program capable of continuously maintaining motivation even when there is unexpected play in which a golf player, especially a beginner, greatly exceeds a prescribed number of strokes while attempting to achieve a target total score. [Solution] The case of finishing a hole with a score two strokes higher than a prescribed number of strokes for each hole of a golf course and the case of finishing a hole with a score one stroke higher than the same are set for each hole as first expected play and second expected play, respectively. A target value for a total score and the difference in the number of strokes between the prescribed number of strokes and the actual play for each hole are inputted from a portable terminal 10. The inputted difference in the number of strokes and the target value for the total score are used to calculate a possible combination of a maximum number of times of the first expected play and a number of times of the second expected play for the remaining holes, with the target value for the total score as an upper limit, a predicted value of the total score is also calculated on the basis of the combination of these numbers of times, and the results are displayed on the portable terminal 10.

Description

Golf error management support device and golf error management support program

[0001] The present invention relates to a golf error management support device and a golf error management support program that are suitable for golf players, particularly beginners, to achieve their own target score (target total score).

[0002] Golf is a sport in which scores are greatly affected not only by the weather, but also by how well you are doing that day and any form issues you may not even be aware of. It is also a sport in which it is difficult to maintain high motivation throughout the course in order to achieve your target score. Beginners, who have little experience on the course and low skill, find it particularly difficult to maintain motivation to play and achieve their target score compared to intermediate and advanced players.

[0003] Known golf applications for mobile devices include those that measure and display the shape and distance of the golf course, the positional relationship of the golf player, and those that simply add up the golf score and display the result. Intermediate to advanced golf players can use these applications to calmly aim to play each hole at par (the prescribed number of strokes).

[0004] On the other hand, when a beginner golf player sets a target score and plays with a par, it is not realistic. Also, if a beginner loses a lot of points during the course (for example, a triple bogey or worse), it is often difficult to maintain motivation for the rest of the game.

[0005] The golf play support system of Patent Document 1 receives information about golf play, such as player information, team information, score information, and hole information, from a database of a management computer onto the golf player's mobile terminal, thereby displaying and checking rankings and scores in real time while playing. The golf play support device of Patent Document 2 displays, on the screen of the golf player's mobile terminal, a green diagram, the straight-line distance from the golf player's current position to the pin on the green, and the player's reference line to the pin, and displays support information from the player's perspective according to the player's current position, allowing the player to improve their score.

[0006] JP 2003-220166 A Japanese Patent No. 6470823 A

[0007] However, while the golf play support systems of Patent Documents 1 and 2 mentioned above are useful for intermediate and advanced players to improve their play and score by quickly determining how to tackle the course, beginners find them difficult to use and are more likely to lose motivation when they see their own ranking and the displayed course distance.

[0008] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a golf error management support device and a golf error management support program that enable golf players, especially beginners, to maintain their motivation to achieve their target total score even if they make an unexpected play that greatly exceeds the specified number of strokes during the course.

[0009] In order to solve the above problems, the golf error management support device of the present invention is a golf error management support device equipped with a portable computer, comprising: means for setting, for each hole, a first expected play when the player finishes that hole with a score two strokes more than the specified number of strokes for a specified number of strokes for that hole; means for setting, for each hole, a second expected play when the player finishes that hole with a score one stroke more than the specified number of strokes for that specified number of strokes for that hole; means for inputting a target total score; means for inputting, after the completion of each hole, the difference in the number of strokes between the specified number of strokes and the actual play for each hole; means for calculating a combination of the maximum number of first expected plays and the number of second expected plays possible for the remaining holes, from the difference in the number of strokes between the specified number of strokes and the input actual play and the input target total score, with the target total score as the upper limit; means for displaying, for each hole, the calculated combination of the maximum number of first expected plays and the number of second expected plays; The first feature of the golf course prediction system is that it has: a means for calculating a predicted total score for each hole based on a combination of the calculated maximum number of first expected plays and the calculated number of second expected plays; and a means for displaying the calculated predicted total score for each hole.

[0010] The golf error management support device according to the present invention is secondly characterized in that it has a means for displaying, after the completion of each hole, the effective number of strokes remaining until the target total score is reached, relative to the total number of strokes required for the golf course.

[0011] The third feature of the golf error management support device of the present invention is that it has a means for switching between input and display screens for when a round starts on the outside course and ends on the inside course, input and display screens for when a round starts on the inside course and ends on the outside course, and input and display screens for when a round is played in half.

[0012] A fourth feature of the golf error management support device according to the present invention is that it comprises means for alerting the player when the predicted total score exceeds the target total score.

[0013] The golf error management support program of the present invention includes a portable computer including: means for setting, for each hole, a first expected play when the player finishes a hole with a score two strokes more than the specified number of strokes for a specified number of strokes for each hole on the golf course; means for setting, for each hole, a second expected play when the player finishes a hole with a score one stroke more than the specified number of strokes for a specified number of strokes for each hole on the golf course; means for inputting a target total score; means for inputting, after the completion of each hole, the difference in the number of strokes between the specified number of strokes and the actual play for each hole; means for calculating a combination of the maximum number of first expected plays and the number of second expected plays possible for the remaining holes, from the difference in the number of strokes between the specified number of strokes and the input actual play and the input target total score, with the target total score set as the upper limit; means for displaying the calculated combination of the maximum number of first expected plays and the number of second expected plays for each hole; The first feature of the present invention is that it functions as: a means for calculating a predicted total score for each hole based on a combination of the calculated maximum number of first expected plays and the calculated number of second expected plays; and a means for displaying the calculated predicted total score for each hole.

[0014] A second feature of the golf error management support program of the present invention is that it further functions as a means for displaying, after the completion of each hole, the effective number of remaining strokes up to the target total score value relative to the total number of strokes required for the golf course.

[0015] The third feature of the golf error management support program of the present invention is that it has a means for switching between input and display screens for when a round starts on the outside course and ends on the inside course, input and display screens for when a round starts on the inside course and ends on the outside course, and input and display screens for when a round is played in half.

[0016] A fourth feature of the golf error management support program according to the present invention is that it further functions as a means for alerting the player when the predicted total score exceeds the target total score.

[0017] By using the golf error management support device of the present invention, even if a golf player, especially a beginner, encounters an unexpected situation such as hitting a big shot on a hole, the player can continue playing while visually checking on the player's mobile device the number of expected play combinations that will allow the player to exceed the specified number of strokes while still within the target total score range for the remaining holes, thereby maintaining high motivation for future play toward achieving the target total score.In addition, by having the player manage expected plays themselves, the occurrence of unexpected plays can be prevented as much as possible.

[0018] Furthermore, if a large discrepancy occurs between the target total score and the predicted total score midway through the course, the target total score can be reset, allowing the player to regain motivation and work towards a new goal, thereby increasing the likelihood that the player will achieve the target total score.

[0020] 1 to 6 show an embodiment of the present invention, in which the reference character S designates a golf error management support device.

[0021] The golf error management support device S (hereinafter referred to as "support device S") is a device that supports a golf player (hereinafter sometimes referred to as "player") in managing his or her own play and the number of times he or she plays to achieve an expected score that exceeds the specified number of strokes on each hole, in order to achieve a target total score that he or she has set for himself or herself, and is used by installing a golf error management support program in a mobile terminal (computer) 10 carried by the player. Figure 1 shows a display screen G1 of the mobile terminal 10, and an example of the installed support program is displayed on the display screen G1.

[0022] As shown in FIG. 1, a main input display section a, an outside course input display section b, and an inside course input display section c are arranged on the display screen G1 of the mobile terminal 10 in this order from the top by the operation of the assistance program.

[0023] The main input display section a has the items [Date], [Start Time], and [Golf Course] listed on the top row, and the items [OUT-IN / IN-OUT], [PAR], [AIM], [Avail], [Result], and [Total] listed on the bottom row.

[0024] The player inputs the [Date], [Start Time], and [Golf Course]. [OUT-IN / IN-OUT] doubles as a switching operation button 21, and by clicking it, it is possible to switch between the [OUT-IN] display (Fig. 1) and the [IN-OUT] display (Fig. 7). When the [OUT-IN] display (Fig. 1) is selected, the outside course input display section b is arranged on the top row and the inside course input display section c is arranged on the bottom row. When the [IN-OUT] display (Fig. 7) is selected, the inside course input display section c is arranged on the top row and the outside course input display section b is arranged on the bottom row. This corresponds to when starting on the outside course and when starting on the inside course, respectively.

[0025] When the [OUT-IN] display (Figure 1) is selected, the player enters the total number of strokes required for the out course (holes 1-9) on the left side of the lower section of the same item, and the total number of strokes required for the in course (holes 10-18) on the right side.When the [IN-OUT] display (Figure 7) is selected, the player enters the total number of strokes required for the in course (holes 10-18) on the left side of the lower section of the same item, and the total number of strokes required for the out course (holes 1-9) on the right side.

[0026] [PAR] is the total number of strokes required for the round (outside and inside courses) that is automatically calculated from the total number of strokes required for the outside courses and the total number of strokes required for the inside courses entered by the player, and is displayed.

[0027] [AIM] allows the player to input a target total score (for example, 99). The total score refers to the total score (strokes) for each hole after the player has completed a round of holes 1 through 18.

[0028] [Avail] is calculated from the total required number of strokes for the round ([PAR]) and the target total score ([AIM]) and displays the remaining number of strokes (for example, +27) that can be exceeded before achieving the target total score.

[0029] [Result] displays the total number of strokes over the required number of strokes after the round is completed (for example, +27), and [Total] displays the actual total score after the round is completed (for example, 99).

[0030] The outside course input display section b has the following items arranged for the 1st to 9th holes (1H to 9H) on the outside course: [Hole], [Par], [over], [putt], [remain], [D-Bog.], [Bogey], and [expect]. At the bottom, there is a [sub] item showing the aggregated results for the 1st to 9th holes.

[0031] [Par] is the standard number of strokes for each hole (1H-9H), [over] is the actual number of strokes over par (number of strokes over par) for each hole (1H-9H), and [putt] is the number of putts (number of strokes from hitting the green to putting it in the hole) for each hole (1H-9H), and each is entered by the player. If the actual number of strokes is par, enter 0; if it is more than par, enter the over (plus) number of strokes; if it is less than par, enter the under (minus) number of strokes.

[0032] [Remain] calculates and displays the remaining number of strokes that can be achieved over the total required number of strokes at the end of the hole (including the inside course) to achieve the target total score based on the data in both the [Avail] and [Over] items.

[0033] [D-Bog.] calculates and displays the maximum number of first expected plays (double bogeys) possible for the remaining holes at the end of the hole (the required number of strokes plus two strokes), assuming that the target total score will be achieved, i.e., the maximum number of double bogeys allowed for the remaining holes.

[0034] [Bogey] calculates and displays the maximum number of possible first expected plays (double bogeys) scores (standard number of strokes + 2 strokes) combined with the number of possible second expected plays (bogeys) scores (standard number of strokes + 1 stroke) at the end of the hole, assuming that the target total score is achieved.

[0035] In [expect], a predicted final total score is calculated and displayed based on the maximum number of first expected plays (double bogeys) calculated as the [D-Bog.] item and the number of second expected plays calculated as the [Bogey] item.

[0036] The bottom row, [sub], displays the tally results for the outside course (1H to 9H), including the [Par] tally (e.g., 36), [over] tally (e.g., +14), [putt] tally (e.g., 18), and score (e.g., 50).

[0037] The inside course data input display section c has the following items for the inside course holes 10 to 18 (10H to 18H): [Hole], [Par], [over], [putt], [remain], [D-Bog.], [Bogey], and [expect]. At the bottom, there is a [sub] item showing the aggregated results for holes 10 to 18.

[0038] The meanings of the items [Par], [over], [putt], [remain], [D-Bog.], [Bogey], and [expect] in the inside data input display section c are the same as those of the items in the outside data input display section b, and explanations of each will be omitted.

[0039] 2 shows the configuration of the golf error management support device S (mobile terminal 10). The support device S includes a communication unit 11, an input operation unit 12, a switching operation unit 13, a setting unit 14, a storage unit 15, a calculation output unit 16, a display unit 17, a memory unit 18, and a control unit 19.

[0040] As shown in Fig. 3, the communication unit 11 communicates with an external server 200 via a network 100. The input operation unit 12 installs the golf error management support program from the server 200 into the mobile terminal 10 through input operations. Golf course information can be input by the player himself or herself, or data can be imported from the server 200. In addition, the target total score can be reset (re-input) during the course.

[0041] The switching operation unit 13 switches between the [OUT-IN] display (FIG. 1) and the [IN-OUT] display (FIG. 7) by clicking the switching operation button 21. When playing a half round, the display can be switched between the [OUT] display (FIG. 8) and the [IN] display (not shown).

[0042] The setting unit 14 sets the specifications of the golf error management support program installed in the mobile terminal 10 through input operations from the input operation unit 12. For example, in the [expect] item, it is possible to change and set the color display when the predicted total score is equal to or less than the target total score, and the color display when the predicted total score exceeds the target total score.

[0043] The storage unit 15 has a program storage unit and a data storage unit. The program storage unit stores a golf error management support program, and the data storage unit stores course information, player information, and actual player data (target total score, over-strokes for each hole, number of putts, actual final total score, etc.).

[0044] The calculation output unit 16 calculates and outputs data for each of the items [PAR], [Avail], [Result], and [Total] in the main data input display unit a, data for each of the items [remain], [D-Bog.], [Bogey], and [expect] in the outside data input display unit b, and data for each of the items [remain], [D-Bog.], [Bogey], and [expect] in the inside data input display unit c.

[0045] For example, referring to FIG. 1 , [D-Bog.][Bogey] is calculated as follows: at the end of the first hole (1H), the player is two strokes over par, and the remaining number of strokes that can be over par on the remaining holes (2H-18H) to achieve the target total score of 99 is 25. Therefore, if the maximum number of double bogeys within the first expected play is X and the number of bogeys within the second expected play is Y, then 2X+Y=<25, and X+Y=17, so the maximum value of X is 8, and Y=9. In other words, the maximum number of double bogeys ([D-Bog.]) that can be made on the remaining holes (2H-18H) to achieve the target total score of 99 ([Bogey]) is calculated as 8, and the number of bogeys combined with the maximum number of double bogeys is calculated as 9. The predicted total score ([expect]) is calculated as 72+2+2×8+1×9=99.

[0046] The display unit 17 displays the corresponding data on the display screen of the mobile terminal 10 in each item of the main data input display section a, each item of the outside data input display section b, and each item of the inside data input display section c.

[0047] The storage unit 18 temporarily stores programs and data installed in the mobile terminal 10, and the control unit 19 controls the functions of the communication unit 11 to the storage unit 18.

[0048] Next, the method of using the golf error management support device S having the above configuration will be explained below, taking a beginner as an example.

[0049] First, a beginner golf player installs the golf error management support program into his / her mobile terminal 10 from the server 200 via the network 100 by inputting data from the input operation unit 12 .

[0050] Next, the player inputs the required number of strokes for each hole on the out course (1H to 9H) and the in course (10H to 18H) by inputting data from the input operation unit 12 on the display screen G1 of the mobile terminal 10 (see FIG. 1). The required number of strokes for each hole may be automatically input by introducing course information registered in the server 200.

[0051] Next, the player inputs a target total score (item name [AIM]). For example, the player inputs "99." The target total score can be reset at any time during the course, for example, if the target total score and the predicted total score deviate significantly from each other.

[0052] When the target total score is input, the remaining number of strokes (item name [Avail]) that can be exceeded before the target total score is reached is calculated and displayed. For example, if the target total score is input as "99," the remaining number of strokes that can be exceeded is displayed as "+27."

[0053] When the player starts playing and finishes each hole, they input the number of overstrokes (item name [over]) and number of putts (item name [put]) for each hole. The remaining number of overstrokes that can be made on the remaining holes until the target total score is achieved (item name [remain]), the maximum number of double bogeys possible within the range of the target total score at that time (item name [D-Bog.]), and the number of bogeys combined with the maximum number of double bogeys at that time (item name [Bogey]) are calculated and displayed.

[0054] For example, if the first hole (1H) is a par 4 and the player finishes the hole in 6 strokes, the player inputs the number of strokes over par as "2," and the remaining number of strokes over par for the remaining holes (2H-18H) is displayed as "25," the maximum number of double bogeys possible at that point while still achieving the target total score is displayed as "8," and the corresponding number of bogeys is displayed as "9." If the player finishes with a par, the player inputs the number of strokes over par as "0," and if the player finishes with a birdie, the player inputs the number of strokes over par as "-1."

[0055] Once the maximum number of double bogeys and the number of bogeys are displayed, the predicted total score (item name [expect]) at that time is displayed based on the combination of both. If the predicted total score is below the target total score, the background color is displayed in blue (indicating that it is below the target). If the predicted total score exceeds the target total score, the background color is displayed in yellow (indicating that it exceeds the target).

[0056] The minimum number of double bogeys is 0, and in that case the number of bogeys equals the number of remaining holes. In this case, the predicted total score is based on the assumption that each subsequent hole will end with a bogey.

[0057] In the example of Figure 1, the player sets a target total score of "99" and, although he has four double bogeys (+2 strokes) and one unexpected triple bogey (+3 strokes) on the outbound course in the first half, he finishes the first half with a score of 50, setting his predicted total score at the same target total score of "99." When he plays on the inbound course in the second half, he has used up all possible double bogeys (0) toward his target total score (99) by the end of the 12th hole (12H). At the end of the 14th hole (14H), a double bogey causes his predicted total score (100) to exceed the target score (99). However, he makes up for this by scoring bogeys (+1 stroke) or less on the 15th hole and ultimately achieves his target total score (99).

[0058] 4 to 6 show an example in which a player first sets the target total score to "99" (FIG. 4), then resets the target total score to "110" and continues playing (FIGS. 5 and 6).

[0059] As shown in display screen G2 of Figure 4, the player finished the first half of the round on the outside course with a total predicted score of 50, which was the same as the target total score (99). However, in the second half, on the inside course, the 13th and 14th holes (13H, 14H) he took big losses of +5 and +4 strokes respectively, and at the end of the 14th hole the predicted total score was 107, making it difficult to achieve the target score. Therefore, as shown in display screen G3 of Figure 5, when the player re-entered the target total score to "110," it was found that the player could achieve the reset target score (110) by playing the remaining holes from the 15th hole onwards (15H to 18H) with three double bogeys (+2 strokes) and one bogey (+1 stroke).

[0060] Therefore, at the end of the 14th hole, the player checked the information displayed on the display screen G3 of the mobile device 10 (number of over strokes possible on the remaining holes +7, maximum number of double bogeys 3, number of bogeys 1, predicted total score 110), which restored his motivation to play.He then resumed play from the 15th hole (15H), and as shown on the display screen G4 of Figure 6, he played within his expectations with scores of +2 strokes, +2 strokes, +2 strokes, and +1 stroke on holes from the 15th hole onwards, and was able to achieve his reset target score of 110.

[0061] Players, especially beginners, can easily become discouraged when they fall four or five strokes behind midway through the course, which can lower their motivation to continue playing and their motivation to achieve their target total score. However, by using this support device S, the player can check the information displayed on the display screen of the mobile terminal 10 (the number of over-strokes possible for the remaining holes, the maximum number of double bogeys, the number of bogeys, and the predicted total score) at any time after finishing a hole, thereby maintaining or recovering their motivation to achieve their target total score for the remaining holes, and continuing to play while maintaining high motivation.

[0062] FIG. 7 shows another embodiment, which, unlike the examples shown in FIGS. 1 to 6, illustrates a use example in which a round starts on the inside course and ends on the outside course. As shown in FIG. 7, clicking the switch operation button 21 on the display screen G5 of the mobile device 10 switches the display from [OUT-IN] to [IN-OUT]. The items in the inside course data input display section c are displayed in the upper row, and the outside course data input display section b is displayed in the lower row. The player can enter a target total score, enter the required number of strokes for holes 10 through 18 in the inside course data input display section c in the upper row, and the required number of strokes for holes 1 through 9 in the outside course data input display section b in the lower row, and then begin play.

[0063] 8 shows yet another embodiment, which is an example of use when playing half of a round (18 holes), i.e., a half round. In the illustrated example, the nine holes (1H to 9H) on the outer course are shown as a half round.

[0064] In this embodiment, when the player clicks the switching operation button 21 on the display screen G6 of the mobile terminal 10, the display can be switched in the following order: [OUT-IN] → [IN-OUT] → [OUT] → [IN]. As shown in the illustrated example, when the player clicks the switching operation button 21 on the display screen G6 of the mobile terminal 10 to switch to the [OUT] display, an outside lane data input display section b is displayed on the top row. Note that when the display is switched to the [IN] display, an inside lane data input display section c is displayed on the top row.

[0065] In the [OUT] display of FIG. 8, if the player inputs "36" as the required number of strokes for the out course ([OUT]) and "49" as the target value for the total score ([AIM]), the number of effective strokes remaining ([Avail]) will be displayed as "+13". If the player finishes the first hole with a double bogey (+2 strokes), the maximum number of double bogeys ([D-Bog.]) corresponding to the target value for the total score will be displayed as 3, the number of bogeys ([Bogey]) will be 5, and the predicted total score ([Expect]) will be displayed as "49".

[0066] By checking the information (effective number of strokes remaining for the remaining holes, maximum number of double bogeys, number of bogeys, predicted total score) displayed at any time on the display screen G6 of the mobile terminal 10, the player can maintain motivation and continue playing toward achieving the target total score.

[0067] According to the above embodiment, by utilizing this support device S, golf players, especially beginners, can prevent a decrease in motivation due to unexpected errors (triple bogey or more) that occur during play, and can control their own motivation so that their play remains within expected errors (double bogey or less).

[0068] In the above embodiment, a double bogey (+2 strokes) is set as the first expected play, a bogey (+1 stroke) as the second expected play, and a triple bogey (+3 strokes) or more as the unexpected play, but this is not limiting. For beginners who have just started playing golf, an exceptional case may be made in which a triple bogey (+3 strokes) is set as the first expected play and a double bogey (+2 strokes) as the second expected play. In this case, the title of each item is changed appropriately depending on the content.

[0069] Thus, according to the present invention, it is possible to provide a golf error management support device and a golf error management support program that enable golf players, especially beginners, to continue playing while maintaining their motivation to achieve the target total score that they have set for themselves.

[0070] The present invention can be used as a golf error management support device and a golf error management support program.
