Hereinafter, the present invention will be described in detail through examples. Objects, features, and advantages of the present invention will be easily understood through the following embodiments. The present invention is not limited to the embodiments described herein and may be embodied in other forms. The embodiments introduced herein are provided so that the disclosed content may be thorough and complete, and the spirit of the present invention may be sufficiently transmitted to those of ordinary skill in the art to which the present invention pertains. Therefore, the present invention should not be limited by the following examples.

In the present specification, terms such as first and second are used to describe various elements, but the elements should not be limited by such terms. These terms are only used to distinguish the elements from each other. Further, when it is mentioned that an element is above another element, it means that it can be formed directly on another element or that a third element can be interposed between them.

In addition, the shape of the elements shown in the drawings may be slightly changed due to variations in the manufacturing process. Accordingly, the embodiments disclosed in the present specification should not be limited to the shapes shown in the drawings unless otherwise specified, and should be understood as including some degree of modification.

1 is a diagram showing a schematic configuration of a portable virtual golf system according to an embodiment of the present invention, and FIG. 2 is a diagram showing a schematic structure of a simulated golf club that can be used in the portable virtual golf system of FIG. 1, and FIG. 3 Is a block diagram of a detection module in the simulated golf club of FIG. 2, FIG. 4 shows an example of a swing trajectory that can be detected when swinging with the simulated golf club of FIG. 2, and FIG. 5 is a portable virtual golf club of FIG. A diagram for explaining a method of calculating a trajectory of a golf ball in a golf system.

Referring to FIG. 1, the portable virtual golf system according to the present embodiment includes a simulated golf club 1 and a mobile device 10. The simulated golf club 1 may wirelessly communicate with the mobile device 10 by having a module enabling wireless communication. The mobile device 10 performs a related operation so that the user can play virtual golf. Specifically, the mobile device 10 has a display to show a virtual golf course and a virtual golf ball that the user wants to play. When the user makes a swing motion with the simulated golf club 1, the user's swing is related. Information is received from the simulated golf club 1, and based on the received information, it is possible to calculate the trajectory of the virtual golf ball flying by the user's swing. As the mobile device 10 capable of such an operation, a user's own mobile phone such as a smart phone may be used. For example, the user's smartphone can be used as the mobile device 10 by installing related software that enables the above operation on his/her smartphone.

The simulated golf club 1 is used when a user makes a swing motion for a virtual golf ball displayed on the mobile device 10. At this time, the user's swing motion is not intended to hit the actual golf ball, but is a kind of simulated swing targeting an imaginary golf ball that is not real. When the user makes a swing motion, information on the swing motion is transmitted to the mobile device 10. The mobile device 10 is provided with a calculation unit 11, and the calculation unit 11 performs a role of calculating a trajectory of a golf ball based on a user's swing motion. Hereinafter, a detailed structure of the simulated golf club 1 and a calculation operation in the calculation unit 11 will be described with reference to the drawings.

2, the simulated golf club 1 includes a grip portion 2, a body portion 3, and a head portion 4. The grip part 2 is formed at one end of the body part 3 and corresponds to a part that the user grabs when swinging. The body part 3 has a shape extending in a predetermined direction, and is a part constituting the body of the simulated golf club 1. The head part 4 is formed at the other end of the body part 3, and is a part that is assumed to impact the golf ball when the user swings. The simulated golf club 1 is not used for hitting an actual golf ball, but is used for taking a swing motion without a golf ball. Therefore, the actual golf ball is not impacted on the head portion 4, but when an imaginary golf ball to be hit is assumed, the imaginary golf ball is impacted.

The simulated golf club 1 is provided with a detection module 5 that can serve to detect a user's swing motion. As shown in FIG. 2, the detection module 5 may be built into the simulated golf club 1. Referring to FIG. 3, the sensing module 5 may include a sensing means 5a, a processor 5b, a transmission/reception means 5c, and a vibration means 5d.

The sensing means 5a includes at least one or more sensors capable of sensing a user's swing motion. For example, the sensing means 5a may include a speed sensor for measuring speed and/or acceleration in the three-axis directions orthogonal to each other, and an angular speed sensor for measuring angular speed in the three-axis directions orthogonal to each other. The sensing signals sensed by each sensor of the sensing means (5a) are transmitted to the processor (5b), and the transmitted sensing signals are converted into various digital signals by the processor (5b) to transmit and receive means (5c) at regular time intervals. It can be transmitted to the outside through.

4, when a user takes a swing motion using a simulated golf club 1, information sensed by the detection module 5 at a predetermined swing position during the swing motion at a certain time interval is transmitted to an external mobile device. It can be transmitted to the device 10, and as a result, it is possible to grasp the swing trajectory of the user as a whole. When the user's swing motion is detected and transmitted to the mobile device 10, the mobile device 10 analyzes the swing motion, and then, assuming that the golf ball hits the golf ball with the swing, what trajectory the corresponding golf ball represents. It calculates how much distance it represents, and the image of moving the golf ball according to the calculated result is displayed to the user on the mobile device 10. Calculating the trajectory or the flying distance may be performed by the calculation unit 11 provided in the mobile device 10.

Various methods may be used to calculate the trajectory or flying distance of the golf ball in the calculation unit 11. In the simplest way, the speed at the moment when it is judged that the swing motion of the user by the simulated golf club 1 impacts the imaginary golf ball can be grasped, and the flying distance can be calculated in proportion to the speed. Alternatively, you can calculate the trajectory of a golf ball with a slightly complicated process as follows.

5, a user hits a golf ball (B0) in a static state (V0, θ0) with a simulated golf club (1) to change the state to a golf ball (B) having a predetermined motion state (V, θ). Assume that The V0, θ0, V, and θ are parameters representing the physical state of the golf ball and refer to the initial speed, the initial angle, the speed after the strike, and the angle after the strike. The angle may represent an azimuth angle indicating a direction on a horizontal plane of the golf ball, or a vertical angle indicating an angle at which the golf ball is inclined with respect to the horizontal plane. Parameters such as speed and angle mentioned herein are shown as examples, and other parameters such as spin may be further considered. When calculating the post-strike speed and post-strike angle, the data sensed by the simulated golf club 1 during the user's swing motion is used. For example, after grasping the swing angle, swing speed, etc. at the time considered to be impacted with the golf ball, when hitting the golf ball by the above angle and speed, etc., the amount of impact transmitted to the golf ball or the impact direction is considered. Post speed, post strike angle, etc. can be calculated.

Since this simulated golf club 1 does not actually hit a golf ball, it is necessary to determine in which state of the swinging motion with the simulated golf club 1 it is considered to be impacted with the golf ball. Various methods can also be applied here. For example, the position of the simulated golf club 1 when the address operation is completed just before the user swings is stored, and the simulated golf club 1 is the above It can be considered that the golf ball and impact occurred when passing through the memorized location. Alternatively, as an alternative method, the maximum swing speed can be obtained when an impact occurs, so it can be considered that the golf ball and the impact have occurred at the point where the maximum swing speed is achieved. In this way, assuming the change in the state of the golf ball (V0, θ0 → V, θ), the values of parameters (V, θ) such as the speed or angle after hitting the golf ball are calculated. Calculate the final trajectory (S). That is, when it is assumed that a golf ball having the above-described physical parameters (V, θ) is flying outdoors, the trajectory of the corresponding golf ball is calculated.

Here, what kind of golf club the user swings may be considered. In actual golf clubs, there are various types of golf clubs such as woods, irons, and putters, and the trajectory of a golf ball may vary depending on which golf club is swung. The simulated golf club 1 is not composed of various types like an actual golf club, and it is considered that one simulated golf club 1 corresponds to various types of golf clubs in reality. Considering the fact that the actual golf club has a different flying distance and accuracy depending on its type, the simulation golf club 1 checks which actual golf club corresponds to when swinging, and reflects this in the calculation of the trajectory of the golf ball. I can. For example, if an intermediate flying distance value of'D' is calculated from the parameters (V, θ), the final flying distance value is calculated by multiplying the intermediate flying distance value by a constant'K', but the value of the constant'K' It depends on the type. Here, information on what kind of golf club the simulation golf club 1 corresponds to during the current swing (for example, whether the user regards the simulation golf club 1 as the 1st wood and swings or the 7th iron and swings Information on whether or not it was done) may be directly inputted by the user through the mobile device 10 prior to the swing motion. Therefore, according to the user's input value, it is determined what kind of golf club the simulated golf club 1 corresponds to, and this is reflected in calculating the distance or trajectory of the golf ball.

What kind of golf club should be used in a specific situation that occurs during golf play is largely determined. For example, most golf players use drivers for tee shots, sand wedges for bunker shots, and putters for putts. Therefore, even if the user does not input what type of golf club the simulated golf club 1 corresponds to, it is possible to automatically select what type of golf club to use according to the situation of the currently playing user. In this case, the automatically selected golf club can be displayed on the mobile device 10, and when the user hits with the displayed automatically selected golf club, the swing motion with the simulated golf club 1 without changing the option do. In addition, when the user wants to change the automatically selected golf club, the user may directly input the selection of the golf club through the mobile device 10.

Referring again to FIG. 3, the sensing module 5 may perform other roles in addition to sensing the user's swing motion, and for this purpose, the sensing module 5 is provided with a vibration means 5d for generating vibration. There may be. The vibration means 5d may serve to inform the user that a specific situation related to the swing has occurred by generating vibration. For example, if the user takes an address posture when using the simulated golf club 1 and then takes a swing motion for hitting, vibration is generated when the address posture is completed, thereby giving the user a'hit that follows the address action. It can tell you when the'for swing motion' starts. Or, if it is assumed that the golf ball is not hitting the actual golf ball, but it is assumed that the golf ball is hit, the simulated golf club 1 and the assumed golf ball generate vibration at the time when it is recognized that the assumed golf ball is impacted to the user. You can tell the timing. Although not shown in the drawing, a sound means for generating sound may be used instead of the vibrating means 5d as a method of indicating the time of completion of the address or the time of impact with the golf ball, and the detection module 5 includes the detection means 5a. ), a power supply means for supplying power to the processor 5b, the transmitting/receiving means 5c, the vibration means 5d, etc. may be provided.

As described above, according to the portable virtual golf system according to the embodiment of the present invention, when the user swings using the simulated golf club 1, information on the swing motion detected by the simulated golf club 1 is transmitted to the mobile device 10. And the calculation unit 11 of the mobile device 10 calculates the trajectory of the golf ball assumed to have been impacted by the simulated golf club 1 based on the transmitted information, and moves according to the calculated trajectory. Images such as a golf ball and a virtual golf course (the term “virtual” is used in the sense of a golf ball and a golf course displayed on a screen, not an actual golf ball and a golf course) are displayed on the mobile device 10. While repeating this process, the user can play virtual golf, and as a result, the user can use his own mobile phone that can be used as a simulated golf club (1) and a mobile device (10), even if he does not go to the screen golf course. / You can enjoy golf casually anywhere.

6 is a diagram illustrating a schematic structure of another golf club that can be used in the portable virtual golf system of FIG. 1.

Referring to FIG. 6(a), the simulated golf club 1a usable in the portable virtual golf system may be mounted in a detachable manner without the detection module 5 being built therein. Referring to FIG. 6(b), an actual golf club 1b in which the detection module 5 is mounted in a detachable manner may be used in the portable virtual golf system. That is, when the detachable detection module 5 is configured as a separate part, any type of golf club can be used in the portable virtual golf system by physically fixing the detection module 5 to an object. Even if it is not a simulated golf club 1a or an actual golf club 1b, any object to which the detection module 5 can be mounted can be used as a substitute for a golf club to enjoy virtual golf play. Here, the target object is preferably in the shape of an elongated rod so as to give a swing feeling similar to that of a golf swing.

Various methods can be applied to configure the sensing module 5 in a detachable manner. For example, after the detection module 5 is provided with a magnetic material to have magnetism, the detection module 5 is applied to a simulated golf club (1a) or a body of a real golf club (1b). It can be mounted by Alternatively, even if a magnetic material is not used, the sensing module 5 may be configured in a detachable manner by providing a separate mounting means.

Compared with the embodiment described with reference to FIG. 1, there is a difference in that the server unit 20 is further provided, and the simulated golf club 1 and the mobile device 10 are not significantly different from the previous embodiment. Detailed description is omitted. Since the server unit 20 is connected to the mobile device 10 through a network, the mobile device 10 can access the server unit 20 through the Internet or the like. The server unit 20 may perform various support operations required for virtual golf play. For example, in order to use the user's smartphone as the mobile device 10, software that performs operations such as displaying a screen of a virtual golf course and calculating the trajectory of a golf ball is required. You can access the above software by accessing 20). In addition, the user may wish to accumulate and store his or her play record each time he plays virtual golf. The server unit 20 can perform such a record management function, and for this purpose, the server unit 20 has a database 21 ) May be provided. When a user plays virtual golf while accessing the server unit 20 using his or her mobile phone, etc., the corresponding play record may be stored in the database 21, and then the same user Even if the device 10 connects to the server unit 20 to play virtual golf, if the user's identity is verified through a login or the like, a record according to the current play may be sequentially stored in addition to the previous play record. That is, through the database 21, regardless of whether the user has played virtual golf through which mobile device 10, play records for a specific user may be accumulated and stored.

In addition, the server unit 20 may operate to enable virtual golf play using the mobile device 10 only when the user completes login. When the login request is transmitted to the server unit 20 through the mobile device 10 and the user's personal login information is stored in the database 21, the server unit 20 logs in with reference to the database 21. You can decide whether to approve or not. In this case, it is possible to enable virtual golf play through the mobile device 10 only after login is approved. Alternatively, it is possible to enable virtual golf play in guest mode even without logging in. However, in the case of the guest mode, since the user is not specified, it may be difficult to accumulate and store the play records of the user who played as a guest.

In the portable virtual golf system according to the present embodiment, various convenience means may be provided to help the user's golf play. (These convenience means are applied not only to this embodiment, but also to the embodiments described with reference to FIGS. 1 and 7. Can). For example, various information on golf play may be provided. The configuration for performing the function of providing such information may be provided in the server unit 20 or may be provided in the mobile device 10 by installing appropriate software that performs the corresponding function in each mobile device 10.

The information is displayed and provided on the screen of the mobile device 10.

I can. There may be various types of information transmitted by the virtual caddy (VC). For example, referring to FIG. 9(a), a simple cheering message for a user's hit, such as'nice shot', can be delivered through a virtual caddy VC. Alternatively, referring to FIG. 9(b), golf course information that can help a user's play, such as a distance from a current golf ball position to a hole cup, may be transmitted through a virtual caddy VC. Alternatively, referring to FIG. 9(c), advice on golf play that can be practically helpful in attacking a course may be delivered to a user through a virtual caddy VC. The advice on the golf play may be a course strategy advice based on basic information on a golf course regardless of who the user is currently playing. For example, in consideration of the position where the golf ball lies on the golf course in which the user is playing, the distance and direction from this position to the hole cup, etc., it is possible to advise how much distance the user will hit and in which direction.

The advice on golf play may be customized advice that considers who the currently playing user is and to what level he or she has. In the portable virtual golf system according to the present embodiment, customized advice customized to individual users may be generated and provided through a virtual caddy (VC). For this purpose, the server unit 20 may be provided with an advice generation unit 22. Can be (advice generation unit may be provided in individual mobile devices). There can be several methods for generating user-customized advice, and two of them are described as examples. However, there may be other methods other than the two methods of providing golf play advice (hereinafter referred to as'the first and second methods') described below, and these two methods are not completely differentiated from each other, and some Or they can be used in combination.

<Method 1>

In this method, an advice is generated in consideration of the current situation of the user who wants to hit, such as the location of the golf ball, and the user's past play record.

10 is a flow chart showing a schematic process of the first method.

Referring to FIG. 10, the process of generating advice on the golf play includes finding the location information of the virtual golf ball (S11), identifying the situation information of the virtual golf ball (S12), analyzing the user's past play record (S13), and generating the advice. It includes the step of (S14).

In the step of identifying the location information of the virtual golf ball (S11), before the user hits (actually, the swing motion using the simulated golf club 1) in the virtual golf course displayed on the mobile device 10, the virtual golf ball is Identify the location of the location. The position of the virtual golf ball corresponds to the initial starting position in the virtual golf course if the user has not made the first hit (tee shot) on a specific course. In addition, after the user hits, the virtual golf ball moves according to the trajectory calculated by analyzing the hit, so the final landing position after the movement according to the calculation result corresponds to the position of the virtual golf ball in the next hit. . Since the initial starting position is a predetermined position, the position can be easily identified, and the landing position can be determined while calculating the trajectory of the virtual golf ball.

In the step of identifying situation information of the virtual golf ball (S12), situation information in which the virtual golf ball is located is determined from the location information of the virtual golf ball. Information on a virtual golf course in which the user is playing may be stored in the database 21 or the mobile device 10 provided in the server unit 20. The information on the virtual golf course may include map information on an 18-hole golf course of a virtual golf course in which the user is playing and coordinate information at each location on the map. Therefore, by substituting the location or coordinates of the virtual golf ball obtained in the step of identifying the location information of the virtual golf ball (S11) into the information on the virtual golf course the user is currently playing, it is possible to obtain the situation information of the virtual golf ball. have.

The situational information of the virtual golf ball may include a distance between the virtual golf ball and the hole cup, or properties of the terrain where the virtual golf ball is currently located. For example, if the virtual golf course currently being played by the user includes terrain with attributes of green, rough, and fairway, the virtual golf ball's current position to the hole cup distance and virtual It is possible to determine whether the terrain on which the golf ball is located has any attribute among green/rough/fairway.

When the situation information of the virtual golf ball is grasped, after analyzing the user's past play record stored in the database 21 (S13), an advice on the golf play to be provided to the user is generated (S14). Various past play records of users may be stored in the user database. For example, if the user has played virtual golf in the past using the mobile device 10 on the same virtual golf course, the corresponding play record may be stored. In the case of playing after logging in through the server unit 20, since the user's identity is verified, the user's play record is accumulated and stored. If a service provider operating the server unit 20 operates not only a portable virtual golf system but also a plurality of screen golf courses, the server unit 20 may be connected to the plurality of screen golf courses. That is, if the user has played screen golf in any one of the plurality of screen golf courses, a record of play at the screen golf course may also be stored in the database 21 of the server unit 20. That is, if the user played in various ways, such as a portable virtual golf system and a screen golf course, the user's past play record will be very rich, and the richer the past play record, the more advice generated by analyzing the past play record. It can be said that it is objective and highly reliable.

When generating user-customized advice according to the first method as described above, objective and reliable advice can be generated by considering past play records from various sources of the user playing in the context information of the current virtual golf ball. Specifically, if the current virtual golf ball is in the bunker and the user has generally had excellent results from the bunker shot in the past play record, instead of a passive shot to get out of the bunker in response to the current situation, a hole cup is placed by leaving the bunker and landing on the green. You can create advice that recommends aggressive shots that can approach you.

<2nd method>

This method predicts a user's hitting result and provides advice based on the predicted hitting result.

FIG. 11 is a flow chart showing a schematic process of the second method, FIG. 12 is a diagram showing a detailed structure of a database required to generate the advice of FIG. 11, and FIG. 13 is a selection range of various sample groups in the advice generation of FIG. 11 It is a drawing showing.

Referring to FIG. 11, the process of generating advice on golf play according to the present method includes user level calculation (S21), sample group selection (S22), sample group information analysis (S23), hitting result prediction (S24), And generating advice based on the prediction result (S25).

In the user level calculation step S21, the user's golf level may be calculated based on the user's play information. When the log-in system using the server unit 20 described above is applied, the individual user's play record may be stored in the database 21 of the server unit 20. A service for virtual golf is provided while the user's identity is confirmed through login, and the user's play record may be stored in the corresponding user information while the user whose identity is confirmed plays virtual golf. Accordingly, the user's level can be calculated based on the user's play information stored in this way. For reference, in golf, the user's level can be expressed in terms of'handicap'. In general, based on 72 strokes in 18 holes, if the score recorded by the user is 82, the handicap of the user is 10, the difference between 82 and 72. If the handicap is large, it means that the average number of strokes for 18 holes is high, so that the user's golf level is low, and if the handicap is negative, it means that the average score for 18 holes is less than 72 strokes, so the user can be considered to have a high golf level.

Referring to FIG. 12, the database 21 may be configured such that the information storage area is divided according to the calculated user level. That is, a plurality of storage areas may be divided according to a user's golf level, and a storage area for a plurality of users belonging to the corresponding level may be formed in each of the plurality of divided storage areas. For example, suppose that there are different users A, B, C, and D, and users A and B belong to level 1, and users C and D belong to level 2, the database 21 contains users belonging to level 1 The area for users (N1) and the area for users belonging to level 2 (N2) are separated from each other, and the area (P1) for storing information on user A and the area (P2) for storing information on user B are the above. An area P3 that is formed in the level 1 area N1 and stores information about the user C and an area P4 that stores information about the user D may be formed in the level 2 area N2. In the storage areas P1, P2, P3, and P4 for each user, a user's personal information DB, a user's play information DB, and the like may be provided. The user's personal information DB stores the user's personal information and can be used for a login process. The user's play information DB stores the user's play records and can be used to predict hits and generate advice.

The user's level is automatically evaluated based on the user's play record, etc., and may be provided for the user to read or used for generating advice through hit prediction. The user's level is not fixed and may be changed accordingly as the user's play record is updated.

Data stored in the user's play information DB may be used to calculate the user's level. The user's play information DB may store a user's past play record. For example, the average number of strokes, driver distance, fairway landing rate, green accuracy, and average number of putts may be calculated and stored from the user's past record, and at least one of them may be used for level calculation.

The average number of strokes refers to the average value of adding the number of strokes recorded by the user and dividing it by the odd number. In general, in a golf course consisting of a total of 18 holes, adding all the prescribed strokes results in 72 strokes. Professional golfers record strokes in their late 60s or early 70s, and general people can be recognized as advanced if they enter within 80 strokes. In addition to the average number of strokes, driver distance, fairway landing rate, green accuracy, and average number of putts can be used for level calculation. The driver's flying distance refers to the distance the golf ball flies by the driver shot. In golf, reducing the number of strokes is the ultimate goal, so if the distance is longer than others, the possibility of reducing the number of strokes increases. Since the flying distance does not increase simply because the power is good, it can be influenced by technical aspects such as the swing posture and the accuracy of the swing at the time of impact with the golf ball, so the longer the flying distance, the higher the level in golf skill. Fairway landing rate (Driving Accuracy) is a numerical indication of how much the tee shot by the driver will land on the fairway (without falling into the rough or bunker).14 out of 18 holes excluding 4 Par3 holes Shows the number of times the tee shot hits the fairway in the hole, in percent. Green accuracy is the number of times a golf ball is raised to the green below the prescribed stroke in'percent (%)', and is calculated similarly to the fairway landing rate. The average number of putts is calculated by dividing the total number of putts by 18 among 18 hole rounds. For example, if the total number of putts is 30, it is 1.67 (30/18 = 1.666).

In this way, since the driver's distance indicates the driving ability of the driver shot, the fairway landing rate or green accuracy indicates the accuracy of the shot, and the average number of putts indicates the accuracy of the putting, the user's level can be calculated using at least one of them. have.

In the end, the average number of strokes represents the golfer's ability in the overall aspect, and the driver's distance, fairway landing rate, green accuracy, and average number of putts represent the golfer's ability in specific specific aspects. Can be accurately calculated.

Referring to FIG. 11 again, a sample group is selected as a next step following the step of calculating the user's level (S21) (S22). The sample group is selected as a group of users having a level similar to that of the user, including a group of a level to which the currently playing user belongs. For example, as shown in FIG. 13(a), the sample group may be selected from among users having the same level (N) as the currently playing user. Alternatively, as shown in Fig. 13(b), the sample group will be selected from among users having the same level (N) as the currently playing user and one level higher than the currently playing user (N+1). I can. Alternatively, as shown in Fig. 13(c), the sample group includes a user having the same level (N) as the currently playing user, a user having a level higher than the currently playing user (N+1), and the currently playing user. It may be selected from among users having a level N-1 lower than that of the user. Alternatively, the sample group may be selected in another manner not shown in the drawing. For example, the sample group may be selected from among users having the same level as the currently playing user and one level lower than the currently playing user. Alternatively, the sample group may be selected from among users having the same level as the currently playing user and users having a level higher or lower than the currently playing user by several levels.

Referring to FIG. 11 again, when a sample group is selected as above, information on users belonging to the sample group is analyzed (S23). The information analyzed here is used when predicting the impact result. The reason for selecting the sample group is to secure enough data to increase the reliability of the prediction result in predicting the hitting result of the currently playing user. The user's own data currently playing may not be sufficient as the basis data for predicting the hitting result, and the more the amount of the basis data is, the more reliable the prediction result is. However, in order to secure the above data in abundance, in the case of adding data of arbitrary users, if the level difference between the user of the added data and the currently playing user is large, the added data causes the user to be currently playing. The accuracy of predicting the result of hitting may decrease. Accordingly, in order to secure a wealth of data and at the same time accurately predict the hitting result of the currently playing user, in the present invention, data is obtained from a sample group having similar skills as the currently playing user. When selecting a sample group, if sufficient data to predict a hitting result can be secured only by users having the same level as the currently playing user, the sample group can be selected as shown in FIG. 13(a). . In addition, if sufficient data for predicting the hitting result cannot be secured only by users having the same level as the currently playing user, the range of the sample group can be expanded as shown in FIGS. 13(b), (c), etc. have.

Referring to FIG. 11 again, after analyzing past play information of users belonging to the sample group, the hitting result of the currently playing user is predicted based on this (S24). There may be several targets for predictable'hit results' here. For example, you can predict how many strokes you will be holed in in a specific hole before taking a tee shot, or you can predict what the trajectory or distance of a golf ball will be when you take a tee shot in a specific hole, or putt in a specific hole putting situation. You can predict whether you will succeed or fail. That is, various hitting results can be predicted for various situations occurring in golf.

In predicting hitting results for various situations occurring in golf, various calculation methods can be applied for the prediction. For example, when the currently playing user wants to predict the number of strokes to be hole-in in a specific hole before taking a tee shot, the play result (number of strokes) data of the users belonging to the sample group in the specific hole may be used. For example, when the currently playing user wants to take a tee shot in the Par3 hole, User A belonging to the sample group has played 3 times in the hole and plays Bogi (4 hits), Bogie (4 hits), and Par (3 hits). If recorded, extract the data (eg: 2 times, wave 1 time). In addition, if user B of the sample group played twice in the hole and recorded bogie (4 strokes) and buddy (2 strokes), data of (example: 1 time, buddy: 1 time) is extracted. In this way, after extracting the data for all users belonging to the sample group, summing them can form summed data such as "double view: 100 times, view: 200 times, par: 50 times, buddy: 50 times" , Using the sum data, it is possible to probably calculate how many strokes the currently playing user will play in the corresponding hole. For example, the probability of becoming a'double view (6 strokes)' may be calculated as 25% (100 times/(100 times + 200 times + 50 times + 50 times).

As above, prediction of the hitting result can be to calculate the probability of each situation occurring for various situations that can come out as a result. Alternatively, the prediction of the hitting result may be predicting any one of two outcomes of success/failure for a specific situation, as described below.

For example, in a putting situation, it is possible to predict the hitting outcome of whether the putt will succeed or fail. Even at this time, various calculation methods can be applied. For example, when the currently playing user puts in a specific hole of a specific golf course, the success of the putting of the currently playing user may be predicted by analyzing the results of the users of the sample group playing in the same specific hole. For the prediction, first, data that can be used as a basis for determining whether putting is successful or not is extracted from the past play records of the sample group users. For convenience of explanation, it is assumed that there are only two variables that can affect putting by simplifying the calculation model. That is, it is assumed that there are only two variables, the distance (x) between the hole cup and the point where the virtual golf ball is placed at the time of putting, and the putting ability (eg, average number of putts) (y) of the user performing the putting. If user A of the sample group made a past putting on the same golf course as the currently playing user and succeeded in putting under the conditions of x=x1, y=y1, the data (x1, y1, 1) is extracted, and user B If putting fails under the conditions of x=x2 and y=y2, the data of (x2, y2, 0) is extracted. If user C puts multiple times in the past on the same golf course as the currently playing user, data such as (x3, y3, 0) and (x4, y4, 1) are extracted for each of the plurality of times (y is the user In the case of the average number of putts representing the putting ability of, y3 and y4 may be the same because the y value for the user C is constant. In this way, data such as "(x1, y1, 1), (x2, y2, 0), …, (xN, yN, 1)" are extracted for all users belonging to the sample group. Afterwards, when the putting is successful by analyzing the extracted data of "(x1, y1, 1), (x2, y2, 0), …, (xN, yN, 1)" using artificial paper techniques such as machine learning, You can set the model in case of failure, and if you enter the variable values (x _user , y _user ) corresponding to x and y for the currently playing _user accordingly, the putting is successful depending on whether the result value is 0 or 1 Whether or not can be predicted. Here, for convenience of explanation, two variables are assumed to be the basis for determining whether or not the putting is successful, but the accuracy of predicting the hitting result can be improved by adding various variables such as topography or slope of the putting point.

Here, the success of putting has been described, but whether or not a shot will succeed in a specific situation other than putting (for example, a bunker shot or an approach shot) can be predicted in a similar way.

In the above, the process of predicting the hitting result in a specific situation, such as predicting at bats in a specific hole and whether the putting was successful, has been described, but this is only an example to help understanding, and the hitting results can be predicted for other situations not described here. I can. In addition, the calculation process for predicting the hitting result has been described by taking a simple method as an example to help understanding, and in reality, a more complex calculation process may be required, and other calculation methods may be used in addition to the method described above.

Referring again to FIG. 11, after predicting the hitting result, an appropriate advice to be provided to the user is generated based on this (S25). For example, if it is predicted that the currently playing user will hole-in for 6 strokes (bogie) on a specific virtual golf course with a par 5 hole before taking a tee shot, the goal is to target the course with a par that is one level higher than the bogie or bogie. You can grab it and generate advice to meet this goal.

In the above, a method of generating and providing advice on a golf play in playing portable virtual golf using a mobile device has been described, but the method of providing golf play advice can be applied not only to portable virtual golf, but also to other golf plays. For example, it can be applied to virtual golf play in a screen golf course, and can also be applied to actual golf play in an outdoor golf course. Hereinafter, an example in which a method of providing advice on golf play is applied when playing golf in an actual golf course will be described.

FIG. 14 is a diagram showing a schematic configuration of a system in which a method for providing advice for golf play is applied to an actual golf play, and FIG. 15 is a schematic process of a method for providing advice for golf play that can be applied to the system of FIG. 14 It is a flow chart showing.

Referring to FIG. 14, a system 100 to which a method of providing golf play advice is applied includes a mobile device 110 and a server unit 120. The mobile device 110 is connected to the server unit 120 through a wired or wireless network. The mobile device 110 may be used to obtain location information of a golf ball using a GPS (Global Positioning System) satellite 101, and may also be used to display and show advice on golf play to a user. The mobile device 110 may communicate with the server unit 120, receive a signal from the GPS satellite 101, and any device may be used as long as it has a function capable of displaying an advice. For example, as the mobile device 110, a user's own mobile phone possessed by a user using a golf course may be used. Alternatively, as the mobile device 110, a mobile phone belonging to the golf course being used by the user and carrying a caddy that helps play while moving with the user, or a separate mobile device provided at the golf course being used by the user may be used. Is necessary when the user does not have a mobile phone or the user's mobile phone cannot receive signals from the GPS satellites 101. The server unit 120 includes a database 121 and an advice generation unit 122. The database 121 stores personal information of a user and a record of past play, and the advice generation unit 122 generates a customized advice by referring to information stored in the database 121. The generated advice is provided to the user through the mobile device 110, and the advice may be provided through a virtual caddy (refer to the reference numeral'VC' in FIG. 9) to enhance the delivery effect.

The first method and the second method described above may be applied to generate the customized advice. However, since the first and second methods described above target the case where the user plays virtual golf, and this embodiment targets the case where the user actually plays golf, the method for providing advice also includes virtual golf and actual golf. Differences may occur due to differences in golf. Hereinafter, using the first method as an example, a method of providing user-customized advice in actual golf will be described.

Referring to FIG. 15, the process of generating advice on a golf play according to the first method includes obtaining location information of a golf ball (S110), obtaining status information of a golf ball (S120), and analyzing a user's past play record (S130). , Including the step of generating advice (S140).

In the step of obtaining the location information of the golf ball (S110), the location of the golf ball may be determined using the mobile device 110 and the GPS satellite 101. That is, when a user with the mobile device 110 is located close to the golf ball, the location of the mobile device 110 can be regarded as the location of the golf ball, and the location of the mobile device 110 is recognized to provide information on the location of the golf ball. Can be obtained. At this time, the location of the mobile device 110 may be determined by a method in which the mobile device 110 receives a signal from the GPS satellite 101. Here, the case of receiving a signal from the GPS satellite 101 in order to obtain the location information of the golf ball has been described, but it is not necessary to use the satellite signal when obtaining the location information. You can also get it.

Acquiring the location information of the golf ball may be initiated after the user who wants to receive the advice on the golf play requests the provision of the advice. When the user's own mobile phone is used as the mobile device 110, the request may be made through his or her mobile phone. That is, it is preferable not to grasp the location information of the golf ball or generate advice at any time, but to identify the location information of the golf ball and generate the advice only when there is a request from the user.

Subsequently, in the step of obtaining status information of the golf ball (S120), situation information in which the golf ball is located is obtained from the location information of the golf ball. When obtaining the situation information of the golf ball, information stored in the database 121 may be referred. The database 121 stores information on a golf course of an actual golf course currently being played by the user, which may store map information on an 18-hole golf course of the golf course and coordinate information at each location on the map. After receiving the location information of the golf ball, by substituting the location information into the golf course information of the corresponding golf course, the location or coordinates of the golf ball in the golf course the user is currently playing can be grasped, from which the situation information of the golf ball (The distance between the golf ball and the hole cup, the property of the terrain on which the golf ball lies, etc.) can be obtained.

Then, the user's past play record analysis (S130) is performed. The user's past play record refers to the record of the user visiting the golf course and playing in the past.In general, there is a limit to the number of times users visit the actual golf course, so the past play record at the actual golf course is inevitably insufficient in quantity. none. In addition, since it is difficult to install electronic equipment in an actual golf course, it is difficult to automatically record individual play records in detail. Currently, the play record is managed only to the extent that the user himself or an assistant such as a caddy writes and inputs simple matters such as how many strokes he struck in a specific hole.

Therefore, the record of the user's past playing on the actual golf course may not be sufficient to generate adequate advice. In this case, it is possible to refer to the past play record at the screen golf course. Screen golf course can be visited relatively more often because time and cost are saved compared to actual golf course, and various electronic equipment is installed so that individual play records can be automatically recorded in detail. The server unit 120 according to the present embodiment may correspond to a central server operated by a service provider operating a plurality of screen golf courses to manage a plurality of screen golf courses. In this case, the server unit 120 It is connected to communicate with the screen golf course. Accordingly, the individual's play record at the screen golf course may be transmitted to the server unit 120 connected to the screen golf course and stored in the database 121.

In screen golf, a virtual golf course created regardless of an actual golf course is provided, or a virtual golf course modeled on an actual golf course is provided. Using an actual golf course as a model is a computer graphic representation of an actual golf course, and the detailed composition of the course is almost the same as the actual course. Therefore, if the user played on the screen golf course at the virtual golf course A'modeled on the actual golf course A, later, when actually playing golf at the actual golf course A, there is a possibility that the user will play the result similar to the result of playing at the virtual golf course A' . When the record of the user's past play on the actual golf course is not sufficient, the record of the user's playing on the screen golf course can be used as supplementary data to generate an appropriate advice. In particular, the golf course the user is currently playing is modeled as a model. Records of playing on a virtual golf course can be used as a powerful source for generating customized advice.

In this way, in the past play record of the user in this step (S130), in some cases, the record that the user played at the screen golf course may be added to the record that the user actually played at the golf course. By making it quantitatively rich, the objectivity and reliability of the generated advice can be improved.

Finally, the step of generating advice for the golf play (S140) proceeds, and this proceeds in a manner similar to the step of generating advice (S14 in FIG. 10) in the virtual golf play described above.

Meanwhile, the second method described above may be applied as a method of providing advice on golf play in an actual golf course. In this case, in calculating the user level (see S21 of FIG. 11) and analyzing the sample group information (see S23 of FIG. 11), the record of the user or other users of similar level to the user played at the screen golf course is reflected. can do. In addition, by modifying this in applying the second method, by adding the steps of obtaining the location information of the golf ball (S110) and obtaining the situation information of the golf ball (S120) in the first method, after grasping the situation in which the golf ball is currently located, The impact result can be predicted according to the identified current situation and appropriate advice can be provided accordingly.

Although the specific embodiments of the present invention have been examined as described above, those of ordinary skill in the art to which the present invention pertains will be able to understand that the present invention can be implemented in a modified form without departing from the essential characteristics of the present invention. will be. Therefore, the disclosed embodiments should be considered from an explanatory point of view rather than a limiting point of view. The scope of the present invention is shown in the claims rather than the foregoing description, and all differences within the scope equivalent thereto should be construed as being included in the present invention.
