It is 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 is provided with a module that enables wireless communication and can communicate with the mobile device 10 wirelessly. 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. Information is received from the simulated golf club 1, and based on the received information, it is possible to calculate what kind of 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 smart phone can be used as the mobile device 10 by installing the related software enabling the above-described operation on the user's smart phone.

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 is a kind of simulated swing targeting an imaginary golf ball that is not real. When the user makes a swing motion, information about the swing motion is transmitted to the mobile device 10 . The mobile device 10 is provided with a calculator 11, and the calculator 11 serves to calculate the trajectory of the golf ball based on the user's swing motion. Hereinafter, the detailed structure of the simulated golf club 1 and the calculation operation in the calculation unit 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 held by the user when swinging. The body part 3 has a shape that extends 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 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, but is used for taking a swing motion without a golf ball. Accordingly, an actual golf ball does not have an impact on the head 4 , and 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 sensing 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 unit 5a , a processor 5b , a transmission/reception unit 5c , and a vibration unit 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 the speed and/or acceleration in three axial directions orthogonal to each other, and an angular velocity sensor for measuring angular velocities in three axial directions orthogonal to each other. The sensing signal sensed by each sensor of the sensing unit 5a is transmitted to the processor 5b, and the transmitted sensing signal is converted into various digital signals by the processor 5b and transmits and receives the transmitting/receiving unit 5c at regular time intervals. can be transmitted externally.

Referring to FIG. 4 , when a user takes a swing motion using the simulated golf club 1, information sensed by the sensing module 5 at a predetermined swing position during the swing motion at regular time intervals is transmitted to an external mobile device. may be transmitted to the device 10 , and as a result, it is possible to determine what kind of swing trajectory the user swung as a whole. When the user's swing motion is sensed and transmitted to the mobile device 10, the mobile device 10 analyzes the swing motion and then determines what trajectory the golf ball represents when it is assumed that the golf ball is hit with the swing. It calculates how much flying distance it represents, and the image in which the golf ball moves 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 calculator 11 provided in the mobile device 10 .

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

Referring to FIG. 5 , a user strikes a golf ball B0 in a stationary state (V0, θ0) with the simulated golf club 1 to change the state to a golf ball B having a predetermined motion state (V, θ). Assume that has occurred The V0, θ0, V, and θ are parameters representing the physical state of the golf ball and mean an initial speed, an initial angle, a speed after hitting, an angle after hitting, and the like. The angle may represent an azimuth angle indicating the direction of the golf ball on a horizontal plane or an up-down angle indicating an angle at which the golf ball is inclined with respect to the horizontal plane. The parameters, such as speed and angle, mentioned herein are illustrative, and other parameters such as spin may be further considered. When calculating the speed after hitting, the angle after hitting, etc., data sensed from the simulated golf club 1 is used during the user's swing motion. For example, after determining the swing angle, swing speed, etc. at the time of impact with the golf ball, when the golf ball is struck by the angle and speed, the impact amount or the impact direction, etc. transmitted to the golf ball is taken into consideration. After speed, angle after hitting, etc. can be calculated.

Since the simulated golf club 1 does not actually hit the golf ball, it is necessary to determine in which state the golf ball is considered to be impacted during the swing motion with the simulated golf club 1 . Various methods can be applied here as well. For example, the position of the simulated golf club 1 when the user completes the address operation just before swing is memorized, and the simulated golf club 1 is used in the user's swing operation. When passing through the memorized position, it can be considered that the golf ball and the impact occurred. Alternatively, as another method, since the maximum swing speed may be obtained when the impact occurs, it may be considered that the golf ball and the impact occurred at the point where the maximum swing speed is reached. As described above, assuming the change of 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, and then, based on these values, the The final trajectory (S) is calculated. That is, when it is assumed that a golf ball having the above-described physical parameters (V, θ) flies outdoors, the trajectory of the golf ball is calculated.

Here, it may be considered what kind of golf club the user swings with. 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 swinging. The simulated golf club 1 is not constituted of various types like an actual golf club, and one simulated golf club 1 is considered to correspond to various types of golf clubs in reality. Considering that actual golf clubs vary in distance and accuracy depending on the type, check which actual golf club the simulated golf club 1 corresponds to when swinging, and reflect this in the calculation of the trajectory of the golf ball. 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' is the value of the golf club. It will vary depending on the type. Here, information on which type of golf club the simulated golf club 1 corresponds to during the current swing (for example, whether the user swings by considering the simulated golf club 1 as a 1-wood or as a 7-iron and swings information on whether or not it was done) can be directly input by the user through the mobile device 10 by himself/herself prior to the swing operation. Accordingly, according to the input value of the user, it is determined which type 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 type of golf club should be used in a specific situation that occurs during golf play is largely determined. For example, most golf players use a driver for tee shots, a sand wedge for bunker shots, and a putter for putting. Therefore, even if the user does not input which 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 currently playing user. In this case, the automatically selected golf club may be displayed on the mobile device 10, and when the user strikes with the displayed automatically selected golf club, if the user takes a swing motion with the simulated golf club 1 without changing the selection, do. In addition, when the user wants to change the automatically selected golf club, he can directly input the selection of the golf club through the mobile device 10 .

Referring back to FIG. 3 , the detection module 5 may perform a role other than the role of sensing the user's swing motion, and for this purpose, the detection 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, a vibration is generated when the address posture is completed, thereby giving the user a 'blow' following the address action. It can tell you when the 'swing motion' starts. Or, when it is assumed that the golf ball is not hit but the actual golf ball is hit, the simulated golf club 1 and the assumed golf ball are affected by generating vibration at the point in time when the impact is recognized, so that the assumed golf ball is impacted to the user can tell you the time. Although not shown in the drawings, a sound means for generating a sound instead of the vibrating means 5d may be used as a method of indicating the time of address completion 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 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 information of the swing motion sensed by the simulated golf club 1 is transferred to the mobile device 10. is transmitted, and the calculator 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 of golf balls and virtual golf courses (the term 'virtual' is used to mean golf balls and golf courses displayed on the screen, not actual golf balls and golf courses) are displayed on the mobile device 10 . By 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 cell phone that can be used as the mobile device 10, even if you do not go to the screen golf course anytime. /You can enjoy golf anywhere without any burden.

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 sensing module 5 being built in therein. Referring to FIG. 6B , an actual golf club 1b to which the sensing module 5 is detachably mounted may be used in the portable virtual golf system. That is, when the detachable sensing module 5 is configured as a separate part, any kind of golf club can be used in the portable virtual golf system by physically fixing the sensing module 5 to any target object, and must be Even if it is not the simulated golf club 1a or the actual golf club 1b, if it is an object on which the sensing module 5 can be mounted, it can be used as a substitute for the golf club to enjoy virtual golf play. Here, the target object is preferably in the shape of an elongated bar so as to give a swing feeling similar to a golf swing.

Various methods can 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 sensing module 5 is applied to the body of the simulated golf club 1a or the actual golf club 1b with a magnetic force on the metal part. 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.

Compared with the embodiment described with reference to FIG. 1, there is a difference in that the 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. Detailed description will be omitted. The display device D may be any device such as a TV capable of displaying an image. The display device D equally displays the image displayed on the mobile device 10 by a method such as mirroring. Although the mobile device 10 has a small screen size, it may be somewhat inconvenient for users to play virtual golf when playing virtual golf. can enjoy

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

Referring to FIG. 8 , the portable virtual golf system according to the present 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. Detailed description will be omitted. The server unit 20 is connected to the mobile device 10 through a network, so that 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 necessary for virtual golf play. For example, in order to use a user's smartphone as the mobile device 10, software is required to display a screen of a virtual golf course, etc. and calculate the trajectory of the golf ball, etc., and the server unit ( 20) to provide the software. In addition, the user may wish to accumulate and store his or her play record whenever he or she plays virtual golf. The server unit 20 may perform such a record management function, and for this purpose, the server unit 20 includes a database 21 ) may be provided. When a user plays virtual golf while connected to the server unit 20 using his or her mobile phone, the corresponding play record may be stored in the database 21, and thereafter, the same user uses a mobile phone other than his/her mobile phone. Even if the device 10 accesses the server unit 20 to play virtual golf, if the user's own identity is verified through log-in, etc., in addition to the previous play record, the record according to the current play may be sequentially stored. That is, through the database 21 , the play record for a specific user may be accumulated and stored regardless of whether the user played virtual golf through any mobile device 10 .

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 the 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 . may decide whether to approve or not. In this case, virtual golf play may be enabled through the mobile device 10 only after login is approved. Alternatively, virtual golf can be played 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 convenient means may be provided to help the user play golf (these convenient means are applicable not only to this embodiment but also to the embodiments described with reference to FIGS. 1 and 7 ). can). For example, various information about golf play may be provided. The configuration for performing this information provision function may be provided in the server unit 20 or may be provided in the mobile device 10 by installing appropriate software for performing the corresponding function in each mobile device 10 .

The information is provided by being displayed on the screen of the mobile device 10 . In particular, in order to increase the effect of information transfer, as shown in FIG. 9 , after displaying the virtual caddy VC on the screen of the mobile device 10, the virtual caddy VC is configured to deliver necessary information. 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 the user's hitting, such as a 'nice shot', may be delivered through the virtual caddy VC. Alternatively, referring to FIG. 9(b) , golf course information that can help the user play, such as the distance from the current golf ball position to the hole cup, may be transmitted through the virtual caddy VC. Alternatively, referring to FIG. 9(c) , advice regarding golf play that can be substantially helpful in attacking the course may be delivered to the user through the virtual caddy VC. The golf play advice may be course attack advice based on basic information about the golf course regardless of who the user is currently playing. For example, in consideration of the position where the golf ball is placed on the golf course the user is playing, and the distance and direction from this position to the hole cup, it is possible to advise in which direction to hit the target with a certain flying distance.

Advice on golf play may be customized advice considering who the current player is and what level he or she has. In the portable virtual golf system according to the present embodiment, user-customized advice specialized for individual users can be generated and provided through a virtual caddy (VC). (the advice generator may be provided in an individual mobile device). There may be various methods for generating customized advice, and two of them will be described as examples. However, there may be other methods other than the two methods of providing golf play advice described below (hereinafter referred to as 'first and second methods'), and these two methods are not completely distinct from each other, and some Alternatively, they may be used in combination.

<Method 1>

In this method, advice is generated in consideration of the current situation of the user who intends to hit, such as the location 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 on 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. (S14).

In the step of grasping the location information of the virtual golf ball (S11), before the user hits (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 is Find out where you are located. Before the user makes the first hit (tee shot) on a specific course, the position of the virtual golf ball corresponds to the initial starting position on the virtual golf 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 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 grasped, and the landing position can be grasped while calculating the trajectory of the virtual golf ball.

In the step of grasping the situation information of the virtual golf ball (S12), situation information in which the virtual golf ball is placed is grasped from the location information of the virtual golf ball. In the database 21 or the mobile device 10 provided in the server unit 20 , information on a virtual golf course that the user is playing may be stored. The information on the virtual golf course may include map information on the 18-hole golf course of the virtual golf course 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) to the information on the virtual golf course the user is currently playing, the situation information of the virtual golf ball can be obtained. have.

As the situation information of the virtual golf ball, there may be a distance between the virtual golf ball and a hole cup, or a property of a terrain in which the virtual golf ball is currently located. For example, when the virtual golf course currently being played by the user includes terrain having properties 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 It is possible to determine whether the terrain on which the golf ball is located has any properties among green/rough/fairway.

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 then 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 on the same virtual golf course, a corresponding play record may be stored. In the case of playing after logging in through the server unit 20 , since the identity of the user is confirmed, the play record of the user is accumulated and stored. If the service provider operating the server unit 20 operates not only the 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 plays screen golf at any one of the plurality of screen golf courses, the 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 or a screen golf course, the user's past play record will be very rich, and the more the past play record is, the more advice is generated by analyzing the past play record. It can be said to be objective and reliable.

When generating the user-customized advice according to the first method as described above, objective and highly reliable advice can be generated in consideration of the user's past play records from various sources who are playing in the current situation information of the virtual golf ball. Specifically, if the current virtual golf ball is in a bunker and the user has generally excellent bunker shot results in the past play record, rather than a passive shot simply to get out of the bunker in response to the current situation, get out of the bunker and land on the green to make a hole cup You can create advice that recommends aggressive shots that can come close to .

<Second method>

The method predicts a hitting result of the user 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 a detailed structure of a database required for generating the advice of FIG. 11, and FIG. 13 is a selection range of various sample groups in generating the advice of FIG. 11 is a drawing showing

Referring to FIG. 11 , the process of generating advice on golf play according to the present method includes calculating a user level (S21), selecting a sample group (S22), analyzing information of a sample group (S23), predicting a hitting result (S24), and a step of generating advice based on the prediction result (S25).

In the user level calculation (S21) step, the user's golf level may be calculated based on the user's play information. When the login system using the server unit 20 described above is applied, the play records of individual users may be stored in the database 21 of the server unit 20 . A service for virtual golf may be provided in a state in which the user's identity is verified through login, and a play record of the user may be stored in the corresponding user information while the identified user plays virtual golf. Accordingly, the user's level can be calculated based on the stored user's play information. For reference, in golf, the user's level may be expressed in terms of 'handicap'. In general, based on the 18 hole 72 strokes, if the score recorded by the user is 82 strokes, the user's handicap becomes 10, which is the difference between 82 and 72 strokes. 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.

Referring to FIG. 12 , the database 21 may be configured to classify information storage areas according to the calculated user level. 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 divided storage areas. For example, when 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 contains users belonging to level 1 An area N1 for users and an area N2 for users belonging to level 2 are separated from each other, and an area P1 for storing information on user A and an area P2 for storing information on user B are described above. An area P3 for storing information on user C and an area P4 for storing information on user D, which are 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 may be used in the login process. The user's play information DB stores the records played by the user, and may be used to predict hitting 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 may be used to generate advice through hitting prediction. The user's level is not fixed, and may be changed accordingly as the user's play record is updated.

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

Average number of strokes means the average value of adding the number of strokes recorded by the user and dividing it according to the number of odds. In general, on a golf course consisting of a total of 18 holes, adding all the required strokes makes 72 strokes. Professional golfers record the number of strokes in their late 60s or early 70s, and the general public can be recognized as an advanced player if they enter within 80 strokes. In addition to the average number of strokes, driver distance, fairway landing rate, green accuracy, average number of putts, etc. can be used to calculate the level. Driver distance refers to the distance a golf ball flies by a driver shot. Since the ultimate goal in golf is to reduce the number of strokes, if the distance is longer than that of others, the possibility of reducing the number of strokes increases. The flying distance does not increase simply because of strength, but it can be affected by technical aspects such as swing posture and swing accuracy at impact with the golf ball. The fairway landing rate (Driver Accuracy) is a numerical measure of the percentage of the driver's tee shot landing on the fairway (without falling into the rough or bunker). Shows the number of times the tee shot landed on the fairway on the hole in percentage. Green accuracy is expressed as 'percent (%)' of the number of times a golf ball is placed on the green below the standard stroke, 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 a round of 18 holes. For example, if the total number of putts is 30, it becomes 1.67 (30/18 = 1.666).

In this way, the driver's distance indicates the long hitting ability of the driver's shot, the fairway landing rate or green accuracy indicates the shot accuracy, and the average number of putts indicates the putting accuracy. have.

In the end, average number of strokes represents a golfer's ability in a comprehensive way, and driver distance, fairway landing rate, green accuracy, average number of putts, etc., represent a 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 the group of the level to which the currently playing user belongs. For example, as shown in FIG. 13A , 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 (N+1) one step higher than the currently playing user, and the currently playing user. It may be selected from 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 drawings. For example, the sample group may be selected from 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 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 steps.

Referring back to FIG. 11 , when the sample group is selected as above, information of users belonging to the sample group is analyzed ( S23 ). The information analyzed here is used when predicting the hitting 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. The user's own data currently playing may not be sufficient as the basis data for predicting the hitting result, and as the amount of the basis data is abundant, the reliability of the prediction result may be increased. However, in the case of adding data of arbitrary users in order to secure the base data abundantly, if the level difference between the user of the added data and the user currently playing is large, the added data causes The accuracy of prediction of hitting results may be reduced. Therefore, in order to secure abundant data and at the same time accurately predict the hitting result of the currently playing user, the present invention secures data from a sample group having similar ability to the currently playing user. When selecting a sample group, if only users having the same level as the currently playing user can secure enough data to predict the hitting result, the sample group can be selected as shown in Fig. 13(a). . In addition, if sufficient data to predict the hitting result cannot be secured only with users having the same level as the user currently playing, the range of the sample group can be expanded as shown in FIGS. 13(b) and (c). have.

Referring back to FIG. 11 , after analyzing the past play information of users belonging to the sample group, the hitting result of the currently playing user is predicted based on this (S24). Here, there may be various targets of the predictable 'hit result'. For example, it is possible to predict how many shots will be made in a specific hole before the tee shot, or predict what the trajectory or distance of a golf ball will be when a tee shot is made at a specific hole, or putting in a specific hole putting situation You can predict whether it will succeed or fail, etc. In other words, it is possible to predict various hitting results 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 shots a user currently playing will make a hole-in at a specific hole before making a tee shot, the play result (number of strokes) data of users belonging to the sample group at the specific hole may be used. For example, when the currently playing user wants to hit a tee shot on a Par3 hole, user A belonging to the sample group played 3 times on the hole, bogey (4 strokes), bogey (4 strokes), and par (3 strokes). If it was recorded (example: 2 times, par: 1 time), the data is extracted. Also, if user B of the sample group played 2 times at the hole and recorded bogey (4 strokes) and birdie (2 strokes), data of (bogey: 1 time, buddy: 1 time) is extracted. In this way, after extracting data for all users belonging to the sample group, summing them can form summed data such as "double views: 100 times, views: 200 times, par: 50 times, buddy: 50 times", etc. , by using the summed data, it is possible to probabilistically calculate how many strokes the currently playing user will play in the corresponding hole. For example, the probability of 'double bogey (6 strokes)' may 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 that each situation will occur for various situations that may come out as a result. Alternatively, the prediction of the hitting result may be predicting any one of the two results of success/failure for a specific situation, as will be described below.

For example, in a putting situation, it is possible to predict the hitting result of whether the putting will succeed or fail. In this case, various calculation methods may be applied. For example, when a currently playing user puts on a specific hole of a specific golf course, the result of the users of the sample group playing on the same specific hole may be analyzed to predict whether the currently playing user's putting success will be successful. For the prediction, first, data that can be a basis for judging the success or failure of putting 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 as the variable: the distance (x) between the hole cup and the point where the virtual golf ball is placed during 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 past putts on the same golf course as the user currently playing and succeeded in putting under the conditions of x=x1, y=y1, data of (x1, y1, 1) is extracted, and user B If putting fails under the conditions 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), (x4, y4, 1) is extracted for each of the plurality of times (y is user In the case of the average number of putts representing the putting ability of , y3 and y4 can be the same value because the y value for user C is constant). 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. After that, by analyzing the extracted data of "(x1, y1, 1), (x2, y2, 0), ..., (xN, yN, 1)" using artificial intelligence techniques such as machine learning, You can set the model for failure, and accordingly, _{if you input the variable values (x user} , y _user ) corresponding to x and y for the user currently playing, the success of putting depends on whether the result is 0 or 1. It can be predicted whether Here, for convenience of explanation, it is assumed that there are two variables that are the basis for judging the success of putting.

Although the success or failure of the putting has been described here, whether a shot in a specific situation other than putting (for example, a bunker shot or an approach shot, etc.) will succeed can be predicted in a similar way.

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

Referring back to FIG. 11 , after predicting the hitting result, appropriate advice to be provided to the user is generated based on the prediction ( S25 ). For example, if it is predicted that the currently playing user will hit a 6th (bogey) hole in a specific virtual golf course with a par 5 hole before making a tee shot, the goal is to attack the course with a par one step higher than the bogey or bogey. You can grab it and generate advice to meet this goal.

As described above, a method for generating and providing advice on golf play in playing portable virtual golf using a mobile device has been described. This method of providing golf play advice can be applied to other golf plays as well as portable virtual golf. For example, it may be applied to virtual golf play on a screen golf course and may also be applied to playing real golf on an outdoor golf course. Hereinafter, an example in which the advice providing method for golf play is applied when playing golf on an actual golf course will be described.

14 is a diagram showing a schematic configuration of a system in which a method of providing advice on golf play is applied to actual golf play, and FIG. 15 is a schematic process of a method of providing advice on golf play that can be applied to the system of FIG. 14 is a flowchart 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/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 may communicate with the server unit 120 , receive a signal from the GPS satellite 101 , and may use any device as long as it has a function of displaying advice. For example, as the mobile device 110 , a mobile phone owned by a user who uses a golf course may be used. Alternatively, as the mobile device 110 , a mobile phone owned by a caddy belonging to the golf course that the user is using and who helps the player to play while moving with the user or a separate mobile device provided by the golf course that the user is using may be used as the mobile device 110 . It is necessary if you do not have a mobile phone or your mobile phone cannot receive a signal from the GPS satellite 101 . The server unit 120 includes a database 121 and an advice generator 122 . The database 121 stores the user's personal information and past play records, and the advice generator 122 generates customized advice by referring to the information stored in the database 121 . The generated advice is provided to the user through the mobile device 110, and in order to increase the delivery effect, the advice may be provided through a virtual caddy (refer to reference numeral 'VC' in FIG. 9).

The first method, the second method, etc. described above may be applied to generate the user-customized advice. However, since the first and second methods described above target a case in which a user plays virtual golf, and the present embodiment targets a case in which a user plays real golf, in the advice providing method, 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 golf play according to the first method includes obtaining location information of a golf ball (S110), obtaining situation information of a golf ball (S120), and analyzing a user's past play record (S130). , and the step of generating advice (S140).

In the step of acquiring the 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 , and the like. That is, when the user carrying the mobile device 110 is located close to the golf ball, the location of the mobile device 110 can be viewed as the location of the golf ball, and location information of the golf ball is obtained by identifying the location of the mobile device 110 . can be obtained. In this case, 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 a signal from the GPS satellite 101 in order to obtain the location information of the golf ball has been described. However, it is not necessary to use the satellite signal to obtain the location information, and the location information of the golf ball is obtained by other methods. you may get

Acquiring the location information of the golf ball may be started only after a user who wants to receive advice on golf play requests to provide advice. When the user's own mobile phone is used as the mobile device 110 , the request may be made through the user's own 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 generate the advice by grasping the location information of the golf ball only when there is a request from the user.

Then, in the step of obtaining the condition information of the golf ball (S120), the condition information of the golf ball is obtained from the location information of the golf ball. When obtaining the condition information of the golf ball, information stored in the database 121 may be referred to. The database 121 stores information about the golf course of the actual golf course the user is currently playing, and this may store map information on the 18-hole golf course of the golf course, coordinate information at each location on the map, and the like. By substituting the location information into the golf course information of the golf course after receiving the location information of the golf ball, the user can grasp the location or coordinates of the golf ball in the golf course the user is currently playing, and from this, the golf ball situation information (The distance between the golf ball and the hole cup or the properties of the terrain where the golf ball is placed, etc.) can be acquired.

Next, the user's past play record analysis (S130) step proceeds. The user's past play record means a record that the user visited the golf course and played 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 quantitatively insufficient. 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 or an assistant such as a caddy writes and enters simple matters such as how many holes in a specific hole.

Therefore, the record that the user has actually played on the golf course in the past may not be sufficient to generate appropriate advice. In this case, past play records at the screen golf course may 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 devices are installed so that individual play records can be recorded automatically 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, and in this case, the server unit 120 is the plurality of screen golf courses. It is connected to communicate with the screen golf course. Accordingly, an 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 after an actual golf course is provided. Modeling an actual golf course is a computer graphic representation of an actual golf course as it is, and the detailed composition of the course is almost identical to the actual course. Therefore, if the user plays at the virtual golf course A' modeled on the actual golf course A on the screen golf course, when the user actually plays golf at the actual golf course A later, there is a possibility of playing with a result similar to the result of playing at the virtual golf course A'. . When the record that the user has played in the actual golf course in the past is not sufficient, the record that the user has played on the screen golf course can be used as supplementary data to generate appropriate advice, and in particular, a golf course that the user is currently playing is a model. The record played on the virtual golf course can be used as powerful data when generating user-customized advice.

As such, in the user's past play record in this step (S130), in some cases, a record that the user played at the screen golf course may be added to the record that the user actually played in golf, and accordingly, the analysis target data Quantitatively enriching can improve the objectivity and reliability of the generated advice.

Finally, the step of generating advice on golf play (S140) is performed, which is performed in a similar manner to the step of generating advice in virtual golf play (S14 of FIG. 10) 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 (refer to S21 of FIG. 11) and analyzing the information of the sample group (referring to S23 of FIG. 11), the record that the user himself or other users of a 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 location information of a golf ball in the first method (S110) and obtaining condition information of a golf ball (S120) in the first method, the current golf ball situation is identified, It is possible to predict the hitting result according to the identified current situation and provide appropriate advice accordingly.

Although specific embodiments of the present invention have been reviewed as described above, those of ordinary skill in the art to which the present invention pertains 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 restrictive sense. The scope of the present invention is indicated 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.
