It relates to a method for providing advice on golf play using a mobile device capable of receiving advice on golf play in real time using a mobile device.

As the active population of various sports increases, golf is also expanding its base as a popular sport naturally enjoyed by the general public. Therefore, only the golf population has reached millions of people, and golf-related businesses have been greatly activated, and the number of golf courses and driving ranges continues to increase. However, due to the nature of golf courses that require a relatively large space, most golf courses are far from residential areas, and the cost of using golf courses is not low, so people often visit actual golf courses due to time or economic reasons. It's not easy to play.

Recently, simulating devices that can enjoy sports games without going to the field using 3D stereoscopic images and computer simulation technology have been developed and widely spread, and as the base of golf expands, computer simulation technology is applied to golf screens. Golf is growing in popularity. In the case of screen golf, since an image of a golf course is displayed through a screen, there is an advantage in that costs are saved compared to playing in an outdoor field while providing a feeling as if an actual golf game is being played outdoors. However, even if the cost is lower than that of actual golf, the cost of using a screen golf course is higher than that of ordinary computer games, and screen golf also has disadvantages in that it is necessary to visit the screen golf course in person to play screen golf. . Therefore, it is required to develop a technology that can go one step further from screen golf and allow individuals to enjoy golf at a desired time and at a lower cost. In addition, compared to other sports, golf is difficult for beginners to enter because there are many things to know to improve golf skills, such as the posture of the golf swing and how to attack the golf course, so it is difficult for beginners to enter. It is required to develop a technology capable of providing appropriate advice on golf play to individuals who play golf so that beginners and even skilled golfers can further improve their golf skills.

It is a diagram for explaining a method of calculating the trajectory of a golf ball in a golf system.

Referring to FIG. 1 , the portable virtual golf system according to this embodiment includes a mock golf club 1 and a mobile device 10 . The mock golf club 1 may communicate wirelessly with the mobile device 10 by including a module enabling wireless communication. The mobile device 10 performs related operations 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, and when the user makes a swing motion with the simulated golf club 1, related to the user's swing. Information is received from the simulated golf club 1, and based on the received information, it is possible to calculate which trajectory the virtual golf ball will fly 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 enabling the above operation on the user's smartphone.

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

Referring to FIG. 2 , the simulated golf club 1 includes a grip part 2, a body part 3, and a head part 4. The grip part 2 is formed at one end of the body part 3 and corresponds to a part that the user holds when swinging. The body portion 3 has a shape extending in a predetermined direction and is a part constituting the body of the simulated golf club 1. The head portion 4 is formed at the other end of the body portion 3, and is assumed to be impacted by a golf ball during a user's swing motion. The simulated golf club 1 is not used for hitting an actual golf ball, and is used for taking a swing motion without a golf ball. Accordingly, the head portion 4 is not impacted with an actual golf ball, but when an imaginary golf ball to be hit is assumed, this 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 sensing 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 transmitting/receiving means 5c, and a vibration means 5d.

The sensing unit 5a includes one or more sensors capable of sensing a user's swing motion. For example, the sensing unit 5a may include a velocity sensor for measuring velocity and/or acceleration in three axis directions orthogonal to each other and an angular velocity sensor for measuring angular velocity in three axis directions orthogonal to each other. 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 and sent to the transmitting/receiving means 5c at regular time intervals. can be transmitted externally.

Referring to FIG. 4, when a user makes a swing motion using a simulated golf club 1, information detected by the sensing module 5 at a predetermined swing position during the swing motion at regular time intervals is transmitted to an external mobile phone. It can be transmitted to the device 10, and as a result, it is possible to determine which swing trajectory the user swung 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, assuming that the golf ball is hit with the swing, what trajectory the corresponding golf ball represents and A certain flight distance is calculated, and as a result of the calculation, an image of the golf ball moving is displayed to the user on the mobile device 10 . Calculating the trajectory or flight 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 flight distance of the golf ball in the calculation unit 11 . In the simplest way, in the user's swing motion by the simulated golf club 1, the speed at the moment when it is determined to be impacted with an imaginary golf ball can be grasped, and the flight distance can be calculated in proportion to the speed. Alternatively, the trajectory of the golf ball can be calculated through a slightly complicated process as follows.

Referring to FIG. 5, a user hits a golf ball B0 in a stationary state (V0, θ0) with a simulated golf club 1, and changes the state to a golf ball B having a predetermined motion state (V, θ). Assume that has occurred. V 0 , θ 0 , V , and θ are parameters representing the physical state of the golf ball, and mean initial velocity, initial angle, post-hit velocity, post-hit angle, and the like. The angle may represent an azimuth representing a direction of the golf ball on a horizontal plane or an up/down angle representing an angle at which the golf ball is tilted with respect to the horizontal plane. Parameters such as speed or angle mentioned herein are shown by way of example, and other parameters such as spin may be further considered. When calculating the post-hit speed, post-hit angle, etc., data sensed by the simulated golf club 1 during the user's swing motion is used. For example, after figuring out the swing angle, swing speed, etc. at the time when it is considered to be impacted with the golf ball, when hitting the golf ball by the angle and speed, the amount of impact transmitted to the golf ball or the impact direction, etc. It is possible to calculate the after speed, the angle after hitting, etc.

Since the simulated golf club 1 does not actually hit the golf ball, it is necessary to determine in which state during swinging motion with the simulated golf club 1 it is considered to be impacted with the golf ball. Various methods can be applied here as well. For example, the position of the simulated golf club 1 when the address operation is completed immediately before the user swings is stored, and the simulated golf club 1 is moved to the above position in the user's swing motion. It can be considered that an impact with the golf ball has occurred when passing through the memorized position. Or, as another method, since the maximum swing speed can be reached when the normal impact occurs, it can be considered that the impact with the golf ball has occurred at the point where the maximum swing speed occurs. In this way, assuming the state change (V0, θ0 → V, θ) of the golf ball, after calculating the value of the parameter (V, θ) such as the speed or angle after hitting the golf ball, based on this value, the value of the golf ball Calculate the final trajectory (S). That is, when it is assumed that the golf ball having the above physical parameters (V, θ) flies outdoors, it is calculated what trajectory the corresponding golf ball will show.

Here, it may be considered what kind of golf club the user swings. 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 used. The simulated golf club 1 is not composed of various types like actual golf clubs, and one simulated golf club 1 is regarded as corresponding to various types of golf clubs in practice. In consideration of the fact that the distance or accuracy of the actual golf club varies depending on the type, it is checked which actual golf club the simulated golf club 1 corresponds to when swinging, and this is reflected in the trajectory calculation of the golf ball. can For example, if the intermediate distance value of 'D' is calculated from the parameters (V, θ), the final distance value is calculated by multiplying the intermediate distance value by the constant 'K', but the value of the constant 'K' is the value of the golf club. that varies depending on the type. Here, information on what kind of golf club the simulated golf club 1 corresponds to during the current swing (for example, whether the user swings the simulated golf club 1 as a number 1 wood or as a number 7 iron and swings information) may be directly input through the mobile device 10 by the user prior to the swing motion. Therefore, according to the user's input value, it is determined what type of golf club the simulated golf club 1 corresponds to, and this is reflected in calculating the flight distance or trajectory of the golf ball.

It is generally determined which type of golf club should be used in a specific situation occurring during golf play. For example, most golf players use a driver for a tee shot, a sand wedge for a bunker shot, and a putter for a putt. Therefore, even if the user does not input what type of golf club the simulated golf club 1 corresponds to, the type of golf club to be used can be automatically selected according to the situation of the user currently playing. In this case, the automatically selected golf club can be displayed on the mobile device 10, and the user performs a swing motion with the simulated golf club 1 without changing the selected golf club when hitting with the displayed automatically selected golf club. do. Also, if the user wants to change the automatically selected golf club, he or she may directly input the selection of the golf club through the mobile device 10 .

Referring back to FIG. 3 , the sensing module 5 may perform a role other than sensing a user's swing motion. For this purpose, the sensing module 5 is provided with a vibration means 5d for generating vibration. There may be. 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 assumes 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, so that the user can be 'hit' following the address motion. It is possible to inform the start point of the 'swing motion for the purpose'. Alternatively, if it is assumed that the golf ball is hit but not the actual golf ball, vibration is generated at the time when it is recognized that the simulated golf club 1 and the assumed golf ball are impacted, so that the assumed golf ball is impacted to the user. can tell you the timing. Although not shown in the drawing, as a method of indicating the time of address completion or impact with a golf ball, a sound means for generating sound may be used instead of the vibration means 5d, and the sensing module 5 has a sensing means 5a. ), a power supply means for supplying power to the processor 5b, the transmission/reception means 5c, the vibration means 5d, and the like 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, the swing motion information detected by the simulated golf club 1 is transferred 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 calculates the virtual golf ball moving according to the calculated trajectory. Images such as a golf ball and a virtual golf course (the term 'virtual' is used to mean a golf ball and a golf course displayed on a screen, not an actual golf ball and 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 the simulated golf club 1 and his or her mobile phone that can be used as a mobile device 10, anytime without going to the screen golf course. / You can enjoy golf anywhere without any burden.

FIG. 6 is a diagram showing 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 detachably mounted without the sensing module 5 built in therein. Referring to FIG. 6(b) , the actual golf club 1b in which the sensing module 5 is detachably mounted may be used in the portable virtual golf system. That is, in the case where the detachable sensing 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 sensing module 5 to an arbitrary target object. Even if it is not the simulated golf club 1a or the actual golf club 1b, any object to which the sensing module 5 can be attached 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 to give a swing feeling similar to that of a golf swing.

Various methods may be applied to configure the sensing module 5 in a detachable manner. For example, after the sensing module 5 is provided with a magnetic material to have magnetism, the magnetic force of the sensing module 5 is applied to the part made of metal in the body of the simulated golf club 1a or the actual golf club 1b. It can be installed by Alternatively, even if a magnetic material is not used, a separate mounting means may be provided to configure the sensing module 5 in a detachable manner.

Referring to FIG. 7 , the portable virtual golf system according to the present embodiment includes a mock golf club 1, a mobile device 10 and a display device D. Compared to the embodiment described with reference to FIG. 1, there is a difference in that a display device (D) is further provided, and the simulated golf club 1 and the mobile device 10 are not significantly different from the previous embodiment. A detailed description is omitted. The display device D may be any device such as a TV capable of showing images. The display device D displays the same image displayed on the mobile device 10 in a manner such as mirroring. The mobile device 10 has a small screen size, which may cause some inconvenience to the user when playing virtual golf. However, if the display device D is provided as in the present embodiment, the mobile device 10 can conveniently play virtual golf while viewing the image through a large screen. can enjoy

8 is a diagram showing a schematic configuration of a portable virtual golf system according to another embodiment of the present invention, and FIG. 9 is a diagram showing a mobile device screen on which a virtual caddy provides information related to golf play.

Referring to FIG. 8 , the portable virtual golf system according to this embodiment includes a simulated golf club 1 , a mobile device 10 and a server unit 20 . 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. A 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 can perform various support operations required for virtual golf play. For example, in order to use a user's smartphone or the like as the mobile device 10, software that performs operations such as showing a screen of a virtual golf course and calculating the trajectory of a golf ball is required, and a server unit ( 20) to receive the software. In addition, the user may wish to accumulate and store his/her play record whenever playing virtual golf. The server unit 20 can perform such a record management function. To this end, the server unit 20 has a database ) may be provided. When a user plays virtual golf while accessing the server unit 20 using his mobile phone, etc., the corresponding play record can be stored in the database 21, and then the same user can use a mobile phone other than his mobile phone. Even if the device 10 accesses the server unit 20 and plays virtual golf, if the user's identity is confirmed through login or the like, records of the current play may be sequentially stored in addition to the previous play records. That is, through the database 21 , regardless of which mobile device 10 the user played virtual golf with, a play record for a specific user may be accumulated and stored.

In addition, the server unit 20 may operate so that virtual golf play using the mobile device 10 is possible only when the user completes log-in. If 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 may log in by referring to the database 21. can decide whether to approve or not. In this case, virtual golf play may be possible through the mobile device 10 only after login is approved. Alternatively, it is possible to play virtual golf in guest mode 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 play records of users 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 play golf (such convenience means may be applied not only to the present embodiment but also to the embodiments described with reference to FIGS. 1 and 7 ). can). For example, various pieces of information about 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 for performing the function in each mobile device 10 .

The information is displayed and provided on the screen of the mobile device 10 . In particular, in order to increase the effect of transmitting information, as shown in FIG. 9, after displaying a virtual caddy (VC) on the screen of the mobile device 10, the virtual caddy (VC) may transmit necessary information. can Information transmitted by the virtual caddy (VC) may be of various types. For example, referring to FIG. 9(a) , a simple cheering message for a user's hit, such as 'nice shot', may be delivered through a virtual caddy (VC). Alternatively, referring to FIG. 9(b) , golf course information that can help the user's play, such as the distance from the current golf ball position to the hole cup, can be transmitted through the virtual caddy VC. Alternatively, referring to FIG. 9(c) , advice on golf play, which may be substantially helpful in course strategy, may be delivered to the user through a virtual caddy (VC). The advice on golf play may be course strategy advice based on basic information about the golf course, regardless of who is the user who is currently playing. For example, in consideration of the position where the golf ball is placed on the golf course being played by the user, the distance and direction from this position to the hole cup, etc., the user may be advised in which direction to hit with a target distance.

Advice related to golf play may be user-customized advice that considers who the user is currently playing and what level they have. In the portable virtual golf system according to the present embodiment, user-customized advice specific to individual users can be generated and provided through a virtual caddy (VC). (The advice generator may be provided in individual mobile devices). There may be several methods for generating user-customized advice, and two of them will be described as examples. However, there may be other methods other than the two golf play advice methods described below (hereinafter referred to as 'first and second methods'), and these two methods are not completely distinguished from each other, and some of them Alternatively, all of them may be used in combination.

<Method 1>

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

10 is a flowchart showing a schematic process of the first method.

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

In the step of determining the location information of the virtual golf ball (S11), before the user strikes (actually, a swing motion using the simulated golf club 1) in the virtual golf course displayed on the mobile device 10, the virtual golf ball Find out where you are located. Before the user hits the first hit (tee shot) on a specific course, the position of the virtual golf ball corresponds to the initial starting position in the virtual golf course. In addition, since the user hits, the virtual golf ball moves according to the trajectory calculated by analyzing the hit, so the final landing position after moving 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 step S12 of determining the situation information of the virtual golf ball, the position information of the virtual golf ball is obtained from the location information of the virtual golf ball. Information on a virtual golf course being played by a user 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 position or coordinates of the virtual golf ball obtained in the step of identifying the location information of the virtual golf ball (S11) to the information on the virtual golf course currently being played by the user, situational information of the virtual golf ball may be obtained. there is.

Circumstance information of the virtual golf ball may include a distance between the virtual golf ball and the hole cup, a property of a topography where the virtual golf ball is currently located, and the like. For example, in the case where the virtual golf course currently being played by the user includes topography having attributes of green, rough, and fairway, the distance from the current position of the virtual golf ball to the hole cup and the virtual golf ball as context information of the virtual golf ball. The terrain where the golf ball is located can determine which attributes of the green/rough/fairway the terrain has.

When the situation information of the virtual golf ball is grasped, the user's past play record stored in the database 21 is analyzed (S13), and advice on golf play to be provided to the user is generated (S14). Various past play records of the user may be stored in the user database. For example, if the user has played virtual golf in the past using the mobile device 10 in 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, the user's identity is confirmed, and thus the user's play records are accumulated and stored. If a service provider operating the server unit 20 operates a plurality of screen golf courses as well as a portable virtual golf system, the server unit 20 may be connected to the plurality of screen golf courses. That is, if the user has played screen golf at one of the plurality of screen golf courses, a play record 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, a screen golf course, etc., the user's past play record would be very rich, and the richer the past play record, the more advice generated by analyzing the past play record. It can be said to be objective and reliable.

When user-customized advice is generated according to the first method as described above, it is possible to generate objective and highly reliable advice by considering past play records from various sources of the user currently playing in context information of a virtual golf ball. Specifically, if the current virtual golf ball is in a bunker and the user has had excellent bunker shot results based on past play records, in response to the current situation, rather than simply a passive shot to get out of the bunker, get out of the bunker and land on the green to get a hole cup You can generate advice recommending aggressive shots that can come close to .

<Second method>

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

11 is a flowchart showing a schematic process of the second method, FIG. 12 is a diagram showing the detailed structure of a database required for generating advice in FIG. 11, and FIG. 13 is a selection range of various sample groups in generating advice in FIG. 11. 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), It includes the step of 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, play records of individual users may be stored in the database 21 of the server unit 20 . A service for virtual golf is provided in a state in which the user's identity is verified through login, and while the identified user plays virtual golf, a play record of the corresponding user may be stored in corresponding user information. 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 may be expressed as a term 'handicap'. In general, if the score recorded by a user is 82 strokes based on 72 strokes in 18 holes, the user's handicap is 10, the difference between 82 and 72 strokes. If the handicap is large, it means that the average number of strokes in 18 holes is high, so the user's golf level is low.

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

The user's level is automatically evaluated based on the user's play record, etc., and may be provided for the user to view or used to generate advice through hit prediction. The user's level is not fixed, and may change 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 the user's past play records. For example, average number of strokes, driving distance, fairway landing rate, green accuracy, average number of putts, etc. may be calculated and stored from the user's past records, and at least one of these may be used for level calculation.

The average number of strokes means the average value obtained by adding the number of strokes recorded by the user and then dividing it by the number of holes. Generally, in a golf course consisting of a total of 18 holes, the total number of strokes is 72, and professional golfers score in the late 60s or early 70s, and ordinary people can be recognized as advanced players if they get 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 to calculate the level. The driving distance of the driver means the distance that the golf ball flies by the driver shot. Since reducing the number of strokes is the ultimate goal in golf, the possibility of reducing the number of strokes increases if the distance is longer than that of others. Since the distance does not simply increase with good strength, and can be affected by technical aspects such as swing posture or swing accuracy at impact with the golf ball, the longer the distance, the higher the level of golf skill. Fairway landing rate (Driver Accuracy) is a numerical value indicating at what rate a driver's tee shot lands on the fairway (without falling into the rough or bunker). In a hole, it is expressed as a percentage of the number of tee shots landed on the fairway. Green accuracy is the number of times a golf ball is raised on the green below a rule by 'percentage (%)', 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 during an 18-hole round. For example, if the total number of putts is 30, it is 1.67 (30/18 = 1.666).

In this way, the driving distance of the driver indicates the long hitting 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 putting. there is.

After all, the average number of strokes represents the golfer's ability in a comprehensive aspect, and the driving distance, fairway landing rate, green accuracy, and average number of putts represent the golfer's ability in specific aspects in detail. can be accurately calculated.

Referring back to FIG. 11, following the step of calculating the user's level (S21), a sample group is selected as the next step (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 is selected from among users having the same level (N) as the currently playing user and users having a level (N+1) one step higher than the currently playing user. 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 one step higher than the currently playing user (N+1), and a currently playing user. It may be selected among users having a level (N-1) one level lower than the user. Alternatively, the sample group may be selected in another method 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 users having a level 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 batting result. The reason for selecting the sample group is to secure sufficient data to increase the reliability of the prediction result in predicting the hitting result of the user currently playing. Only data of the user currently playing may not be sufficient as evidence data for predicting a batting result, and the more abundant the evidence data, the higher the reliability of the prediction result. However, in order to secure the above data in abundance, when data of arbitrary users is added, if the level difference between the user of the added data and the user currently playing is large, The accuracy of predicting the hitting result may be reduced. Therefore, in order to secure abundant data and at the same time accurately predict the batting result of the user currently playing, data is secured from a sample group having skills similar to those of the user currently playing. When selecting a sample group, if enough data can be secured to predict the hitting result only with users having the same level as the user currently playing, the sample group can be selected as shown in FIG. 13 (a). . In addition, if it is not possible to secure sufficient data to predict the batting result only with 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) and (c). there is.

Referring back to FIG. 11 , after analyzing past play information of users belonging to the sample group, a batting result of a user currently playing is predicted based on this analysis (S24). Here, there may be various targets of the 'hit result' that can be predicted. For example, it is possible to predict how many strokes will be holed in a specific hole before taking a tee shot, or to predict what the trajectory or distance of a golf ball will be when a tee shot is made in a specific hole, or putting in a specific hole putting situation. You can predict whether it 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 may be applied for the prediction. For example, when it is desired to predict how many strokes a currently playing user will hole in a specific hole before making a tee shot, play result (number of strokes) data of users belonging to a sample group in the specific hole may be used. For example, when a user currently playing wants to take a tee shot in a par 3 hole, user A belonging to the sample group has played the hole 3 times, bogey (4 strokes), bogey (4 strokes), and par (3 strokes). If it has been recorded, the data of (Example: 2 times, Par: 1 time) is extracted. In addition, if user B of the sample group played twice in the hole and recorded a bogey (4 strokes) and a birdie (2 strokes), data of (bogey: 1 time, birdie: 1 time) is extracted. In this way, after extracting the data for all users belonging to the sample group and summing them, aggregated data such as "double bogey: 100 times, bogey: 200 times, par: 50 times, birdie: 50 times" can be formed. , Using the sum data, it is possible to probabilistically calculate how many strokes a user currently playing will play in a corresponding hole. For example, the probability of being a 'double bogey (6 strokes)' can be calculated as 25% (100 times/(100 times + 200 times + 50 times + 50 times).

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

For example, in a putting situation, it is possible to predict the result of hitting whether the putt will succeed or fail. Even at this time, various calculation methods may be applied. For example, when a user currently playing puts on a specific hole in a specific golf course, the success of the putt of the user currently playing can be predicted by analyzing results of the users of the sample group playing the same specific hole. For the prediction, first, data that can be used as a basis for determining the success of putting is extracted from past play records of 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 during putting and the user's putting ability (for example, the average number of putts) (y). If user A of the sample group made past putts on the same golf course as the user currently playing and succeeded in putting under the condition of x=x1, y=y1, data of (x1, y1, 1) is extracted, and user B If putting fails under the condition of x=x2, y=y2, data of (x2, y2, 0) is extracted. If user C has putt multiple times in the past on the same golf course as the user currently playing, data such as (x3, y3, 0) and (x4, y4, 1) is extracted for each of the multiple times (where y is the user In the case of the average putting number representing the putting ability of , since the y value for user C is constant, y3 and y4 can be the same value). In this way, data such as "(x1, y1, 1), (x2, y2, 0), ..., (xN, yN, 1)" is extracted for all users belonging to the sample group. Then, by analyzing the extraction data of “(x1, y1, 1), (x2, y2, 0), …, (xN, yN, 1)” using artificial intelligence techniques such as machine learning, the case of successful putting and It is possible to set a model in case of failure, and accordingly, if the variable values (x _user , y _user ) corresponding to x and y are entered for the user currently playing, the putt is successful depending on whether the result is 0 or 1 can predict whether Here, for the convenience of explanation, it is assumed that there are two variables that are the basis for determining the success of putting, but the accuracy of predicting the hitting result can be improved by adding various variables such as the topography or slope of the putting point.

Although the success or failure of a putt has been described here, 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 manner.

Although the process of predicting hitting results in specific situations, such as predicting the number of strokes in a specific hole and the success of putting, has been described above, this is only an example to help understanding, and predicting hitting results in other situations not described here has been described. can In addition, the calculation process for predicting the hitting result has been explained with the simplest possible example to help understanding, but in reality, a more complicated calculation process may be required, and other calculation methods may be used other than the method described above.

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

The method for generating and providing golf play advice while playing portable virtual golf using a mobile device has been described above. This golf play advice providing method 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 on a screen golf course and can also be applied to actual golf play on an outdoor golf course. Hereinafter, an example in which an advice providing method for golf play is applied during golf play at an actual golf course will be described.

14 is a diagram showing a schematic configuration of a system in which an advice providing method 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 , the system 100 to which the golf play advice providing method 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 Global Positioning System (GPS) satellite 101, and may also be used to display and show advice on golf play to a user. The mobile device 110 can communicate with the server unit 120, receive signals sent from the GPS satellites 101, and any device can be used as long as it has a function capable of displaying advice. For example, as the mobile device 110, a mobile phone owned by a user using a golf course may be used. Alternatively, as the mobile device 110, a mobile phone owned by a caddy belonging to the golf course in use by the user and helping to play while moving with the user, or a separate mobile device provided by the golf course in use by the user may be used. This 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 generator 122 . The database 121 stores user personal information and past play records, and the advice generating unit 122 refers to the information stored in the database 121 to create user-customized advice. 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 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 user-customized advice. However, since the first and second methods described above target the case where the user plays virtual golf, and the present embodiment targets the case where the user actually plays golf, the advice providing method also applies to virtual golf and real golf. Differences may occur due to differences in golf. Hereinafter, a method of providing user-customized advice in actual golf will be described using the first method as an example.

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

In the step of acquiring location information of the golf ball ( S110 ), the location of the golf ball may be determined using the mobile device 110 , the GPS satellite 101 , or the like. That is, when the user holding 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 location information of the golf ball is obtained by determining the location of the mobile device 110. 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 or the like. Here, the case of receiving the signal from the GPS satellite 101 to obtain the location information of the golf ball has been described, but it is not necessary to use the satellite signal when acquiring the location information. you can also get

Acquisition of the location information of the golf ball may be initiated after a user who wants to receive advice on golf play requests the provision of advice. If the user's own cell phone is used as the mobile device 110, the request may be made through the user's cell phone. That is, it is preferable to configure the location information of the golf ball to be grasped and advice to be generated only when there is a request from the user, rather than to determine the location information of the golf ball or to generate advice at any time.

Subsequently, in the step of acquiring situation information of the golf ball (S120), situation information about the position of the golf ball is obtained from the location information of the golf ball. Information stored in the database 121 may be referred to when situation information of the golf ball is obtained. The database 121 stores information about a golf course of an actual golf course currently being played by a user, and may include map information about 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 user can grasp the location or coordinates of the golf ball in the golf course currently playing, and from this, the situation information of the golf ball. (The distance between the golf ball and the hole cup or the property of the terrain on which the golf ball is placed) can be obtained.

Subsequently, the user's past play record analysis step (S130) proceeds. The user's past play record refers to the record of the user visiting the golf course and playing in the past. In general, since there is a limit to the number of times users visit an actual golf course, the past play record at the actual golf course is inevitably insufficient in quantity. does not exist. 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, play records are managed only to the extent that a user or an assistant such as a caddy writes and inputs simple details such as how many strokes a hole was made in a specific hole.

Therefore, the record of the user's past play at the actual golf course may not be sufficient to generate appropriate advice. In this case, past play records at the screen golf course can be referred to. Screen golf courses can be visited relatively more frequently because time and cost are saved compared to actual golf courses, and various electronic equipments are installed to automatically record individual play records in detail. The server unit 120 according to this 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. It is connected so that it can communicate with the screen golf course. Accordingly, records of individual play at the screen golf course may be transferred 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 independently of an actual golf course or a virtual golf course modeled after an actual golf course is provided. Modeling an actual golf course is a computer graphic representation of a golf course that actually exists, and the detailed configuration of the course is almost the same as the actual course. Therefore, if the user plays at the virtual golf course A' modeled after the real golf course A on the screen golf course, there is a possibility that he will play with a result similar to the result of playing at the virtual golf course A' when he actually plays golf at the real golf course A later. . When the record of the user's past play at the actual golf course is not sufficient, the record of the user's play at the screen golf course can be used as a supplementary material to generate appropriate advice, especially the golf course the user is currently playing as a model. Records of playing at a virtual golf course can be used as powerful data when creating user-customized advice.

In this way, in the present step (S130), the user's past play record may, in some cases, add the user's play record at the screen golf course to the user's actual golf record, and accordingly, the data to be analyzed By enriching them quantitatively, the objectivity and reliability of the generated advice can be improved.

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

Meanwhile, as a method of providing advice on golf play in an actual golf course, the above-described second method may be applied. In this case, in calculating the user level (see S21 in FIG. 11) and analyzing the information of the sample group (see S23 in FIG. 11), records played by the user himself or other users of similar levels at the screen golf course are reflected. can do. In addition, in applying the second method, it is modified and the current situation of the golf ball is grasped by adding the steps of obtaining golf ball location information (S110) and golf ball situation information (S120) in the first method. According to the identified current situation, the batting result can be predicted and appropriate advice can be provided accordingly.

Although the specific embodiments of the present invention have been reviewed as above, those skilled in the art can understand that the present invention can be implemented in a modified form without departing from the essential characteristics of the present invention. will be. Accordingly, the disclosed embodiments should be considered in an illustrative rather than a limiting sense. The scope of the present invention is shown in the claims rather than the foregoing description, and all differences within the equivalent scope will be construed as being included in the present invention.
