Description

The present invention relates to a virtual golf system. More specifically, it relates to a virtual golf system with a swing plate that can be tilted at a predetermined angle.

Simulation devices have been developed that allow people to enjoy sports games without going to the site using 3D stereoscopic images and computer simulation technology, and virtual indoor sports games such as golf and baseball have become widespread. In the case of screen golf, which is a typical indoor sport, the image of the golf course is displayed through the screen, giving the feeling of playing an actual golf game outdoors, while playing in the outdoor field. Compared to this, it saves time and money, so it is very popular with modern people who have difficulty playing golf due to time and financial reasons.

In fact, golf courses in golf have various terrains such as fairways, roughs, bunkers, water hazards, etc., and these terrains are flat or sloping terrains, and the attributes of these terrains allow the user to play golf. There may be differences in the feel and difficulty of hitting the ball. For example, when hitting on a sloped terrain, the feeling of hitting is different and the difficulty of hitting increases as compared with the case of hitting on a flat ground. In comparison, a swing plate that hits a golf ball on a screen golf course is usually installed on a flat bottom, and it is difficult to reproduce the hitting feeling of hitting a golf ball at an inclined point in actual golf. There is a problem.

When the swing plate is formed so as to be inclined in consideration of the above points, there may be other problems. In other words, some users prefer to reproduce the feeling of hitting on a slope, while others find it inconvenient to hit with a sloped swing plate due to their lack of golf ability. You may disagree. Therefore, it is necessary to develop a system that can meet the needs of various users at the same time while giving the reality of playing actual golf.

The present invention has been invented in consideration of the above circumstances, and by providing a swing plate that can be tilted, it is possible to actually give the reality of golf and at the same time satisfy the needs of various users. The purpose is to provide a virtual golf system.

In addition, other objects of the present invention can be clearly understood from the following description and the accompanying drawings.

In order to achieve the above object, the virtual golf system according to the embodiment of the present invention includes a swing plate on which a golf ball can be placed and tilted, and a display unit for displaying a virtual golf course and a virtual golf ball. .. The user can play in different first and second modes, when the position where the virtual golf ball is placed on the virtual golf course is an inclined point before the user hits the golf ball. In the first mode, the user can hit the golf ball with the swing plate tilted at a predetermined angle, and in the second mode, the user can hit the golf ball with the swing plate not tilted. Can be hit.

The virtual golf system further includes an inclination adjusting means for adjusting the swing plate so as to incline at a predetermined inclination angle, and when the position where the virtual golf ball is placed on the virtual golf course is an inclination point, the said. The tilt angle of the swing plate is adjusted by the tilt adjusting means so as to correspond to the tilt of the tilt point.

In the virtual golf system, the user can select either the first mode or the second mode in advance before the start of play.

The virtual golf system further includes a control unit that calculates the locus of the hit golf ball when the user hits the golf ball, and when the locus of the golf ball is calculated, the display unit is calculated. The virtual golf ball that moves along the trajectory is displayed.

In the virtual golf system, the control unit calculates the locus based on the physical state of the hit golf ball and gives a penalty point to the user hit in the second mode.

In the virtual golf system, the control unit calculates the trajectory based on the physical state of the hit golf ball in the first mode, and the physical state of the hit golf ball in the second mode. After calculating the locus based on the state, the calculated flight distance is reduced by a predetermined distance.

In the virtual golf system, the control unit calculates the trajectory based on the physical state of the hit golf ball in the first mode, and the physical state of the hit golf ball in the second mode. After the state is deformed to reflect the tilt angle of the tilt point where the virtual golf ball is placed, the locus is calculated based on the deformed physical state.

According to the virtual golf system of the present invention, by providing a swing plate that can be tilted, there is an effect that the reality of golf can be actually given and at the same time, the needs of various users can be satisfied.

It is provided to ensure that. Therefore, the present invention should not be limited by the following examples.

In the present specification, terms such as first and second are used to describe various elements, but the elements should not be limited by such terms. This term has only been used to distinguish the elements from each other. Also, when it is mentioned that one layer (membrane) is on another layer (membrane) or substrate, it is formed directly on or between other layers (membranes) or substrate. It means that a third layer (membrane) can also intervene in.

In the drawings, the size of the elements, or the relative size between the elements, can be illustrated with some exaggeration for a clearer understanding of the invention. In addition, the shape of the illustrated element may be changed to some extent due to mutations in the manufacturing process. Therefore, the embodiments disclosed herein should not be limited to the illustrated shapes and should be understood to include some modifications, unless otherwise noted.

FIG. 1 is a schematic configuration diagram of a virtual golf system according to an embodiment of the present invention.

Referring to FIG. 1, the virtual golf system includes a swing plate (10), a control unit (20), a sensing unit (30), an input unit (40), and a display unit (50).

The swing plate (10) corresponds to a batter zone in which a golf ball is placed and hit. In particular, the swing plate (10) according to this embodiment can be tilted at a predetermined angle. This is because the swing plate (10) is provided with tilt adjusting means (see reference numeral 11 in the drawing of FIG. 3) for adjusting the swing plate (10) so as to tilt at a predetermined tilt angle, and the tilt adjusting means will be described later.

The control unit (20) controls the overall operation of each component in screen golf. For example, the control unit (20) can control the tilt adjusting means to control whether the swing plate (10) is kept horizontal or at what angle the swing plate (10) is tilted. Further, the control unit (20) can calculate the trajectory of the hit golf ball when the user hits the golf ball placed on the swing plate (10).

The sensing unit (30) checks the condition of the swing plate (10) on which the golf ball hit by the user is placed, or senses general state information about the golf ball hit by the user. When the detection unit (30) senses the state information of the golf ball hit by the user, the result is transmitted to the control unit (20), which is how the golf ball hit by the user by the control unit (20). It is used as a basis for calculating whether to fly on a proper trajectory. As the sensing unit (30), any sensing means such as a camera capable of photographing the movement of the golf ball or a sensing sensor capable of detecting the movement of the golf ball can be used. The camera, the sensing sensor, and the like can be used alone or together. Also, only one may be used, or more than one may be used.

The input unit (40) is for receiving various information from the user, and a keyboard / mouse or the like can be used. In screen golf, the user inputs information such as when the user inputs his / her ID and password to log in, when the user selects the golf course to be played, the difficulty level, etc. It may have to be done, and an input unit (40) is needed for such cases. The information input from the input unit (40) is transmitted to the control unit (20), and the control unit (20) processes the user's request based on the transmitted information. For example, when a user selects a specific golf course, the necessary processing is performed so that the user can play on that golf course. Specifically, the control unit (20) includes an image processing means for processing an image, and when the user selects a specific golf course, the image processing means displays an image of the selected golf course (50). ) Can be transmitted and displayed. Further, when the user inputs personal information such as an ID and a password for logging in, the control unit (20) checks the input personal information and plays a role of deciding whether or not to approve the login. On the other hand, a service industry that provides a screen golf service can operate a plurality of screen golf courses, in which case the plurality of screen golf courses are managed by a central server connected by a network, and the login process is performed by the central. Can be done by the server.

The display unit (50) includes a beam projector (51) and a screen (52). The beam projector (51) projects a related image onto the screen (51) so that the virtual golf course and the virtual golf ball are displayed on the screen (52), and the screen (52) projects the projected golf-related image. To display and provide to users. In the present specification, the object displayed on the screen (52) can be expressed with the term “virtual”. This means that it does not exist in the real world, but is displayed on the screen (52). For example, "virtual golf course" means a golf course displayed on the screen (52), and "virtual golf ball" means a golf ball displayed on the screen (52).

Although not shown in FIG. 1, a voice processing unit for informing the user of the progress of the game and reproducing various sound effects according to the progress of the game can be provided.

FIG. 2 shows an example of a screen displayed on the screen in the virtual golf system of FIG. 1, FIG. 3 shows in detail the swing plate used in the virtual golf system of FIG. 1, and FIG. 4 shows the tilting mechanism of the swing plate. It is a figure for demonstrating an example.

Referring to FIG. 2, a virtual golf course is displayed on the screen (52), and the virtual golf course reflects an actual golf course. In actual golf, after making the first tee shot, the hit golf ball flies and lands at a specific point, and continues hitting from the landing point. Also in the virtual golf system of the present invention, after making a tee shot with the swing plate (10), the state of the golf ball hit by the sensing unit (30) is detected and transmitted to the control unit (20) to be transmitted to the control unit (20). ) Calculates the flight trajectory when the golf ball is assumed to fly at an actual golf course as per sensed by the sensing unit (30) based on the sensing result. An image of a virtual golf ball (VB) moving based on the calculated result is displayed on the screen (52), and the virtual golf ball (VB) flies based on the calculated result and then screens (52). ), The user lands at a specific point on the virtual golf course, and the user continues to hit from the point where the virtual golf ball (VB) lands.

The point where a golf ball lands in actual golf is a terrain with various attributes such as fairways, roughs, and bunkers, and the virtual golf course on the screen (52) also has virtual fairways, roughs, virtual bunkers, etc. The terrain with various attributes such as can be displayed. Also, in actual golf, the golf ball lands on a horizontal or slope, and the virtual golf course on the screen (52) reflects this. That is, the virtual golf ball (VB) is located at the horizontal position of the virtual golf course as shown in FIG. 2 (a) or the inclination of the virtual golf course as shown in FIG. 2 (b). It can be located in a position.

In actual golf, if the landing point is a horizontal point, when hitting at this landing point, the golf ball is hit in a horizontal state, and if the landing point is a slope point, the golf ball is tilted when hitting at this landing point. Hit in the same state. However, in a conventional screen golf course, since the swing plate on which the golf ball for hitting is placed is always in a horizontal state, there is a problem that it is difficult to experience the feeling of hitting at an inclined point. The swing plate (10) of the virtual golf system according to the present embodiment is configured to reflect the inclination of the point where the virtual golf ball (VB) is located on the virtual golf course. Referring to FIG. 3, the swing plate (10) can be tilted at a predetermined angle by the tilt adjusting means (11). Therefore, when the virtual golf ball (VB) on the screen (52) lands at a horizontal point (see (a) in FIG. 2), the swing plate (10) is horizontal, as illustrated in (a) in FIG. When the virtual golf ball (VB) of the screen (52) lands on the inclined point (see (b) in FIG. 2), the swing plate (10) is shown in (b) of FIG. ) Tilt at a predetermined angle. At this time, the tilt angle of the swing plate (10) can be adjusted to correspond to the degree to which the point where the virtual golf ball (VB) of the screen (52) lands is tilted. For example, when the inclination angles of the points where the virtual golf ball (VB) lands are 5 °, 10 °, and 15 °, respectively, the inclination angles of the swing plate (10) are 5 as well as the inclination of the inclination points. Can be adjusted to °, 10 °, 15 °. Alternatively, when the inclination angle of the point where the virtual golf ball (VB) lands is 5 °, 10 °, or 15 °, the inclination angle of the swing plate (10) is proportional to the inclination of the inclination point at a constant ratio. Can be adjusted to 2.5 °, 5 °, 7.5 °, or 10 °, 20 °, 30 °. Alternatively, other methods not mentioned herein can be configured such that the tilt of the point where the virtual golf ball (VB) lands corresponds to the tilt angle of the swing plate (10). In this way, the control unit (20) can adjust the inclination of the point where the virtual golf ball (VB) has landed and the inclination angle of the swing plate (10) to correspond to each other. Since the control unit (20) calculates the trajectory of the hit golf ball, it can grasp the landing position of the virtual golf ball (VB), and the inclination degree at that position is calculated from the landing position grasped by the landing position. Can be grasped. After grasping the inclination degree of the landing position, the control unit (20) controls the inclination adjusting means (11) provided in the swing plate (10) so as to have an inclination angle corresponding to the inclination degree. As a result, the swing plate (10) can be tilted so as to have an inclination angle corresponding to the inclination of the point where the virtual golf ball (VB) lands.

Referring to FIG. 4, the tilt adjusting means (11) includes a drive source (11a), a shaft member (11b), and gears (11c, 11d). A shaft member (11b) is coupled to the drive source (11a), and gears (11c, 11d) are mounted on the shaft member (11b). A motor is used as the drive source (11a), and when the drive source (11a) is activated, the shaft member (11b) coupled to the drive source (11a) rotates. Pinion gears (11c) and rack gears (11d) that can convert rotary motion into linear motion are used as gears (11c, 11d), and when the shaft member (11b) rotates, the rotary motion is driven by the movement of the gears (11c, 11d). Is converted into linear motion, and the rack gear (11d) can move up and down. The end of the rack gear (11d) is in contact with the lower surface of the middle portion of the swing plate (10). As the rack gear (11d) moves up and down, the relevant portion of the swing plate (10) in contact with the rack gear (11d) is raised or lowered downward. The swing plate (10) is divided into a front portion (10a) and a rear portion (10b) located in the front and rear, respectively, with reference to the intermediate portion in which the rack gear (11d) contacts. When the swing plate (10) is raised upwards, the anterior portion (10a) is tilted toward the front and the rear portion (10b) is inclined toward the rear. Although not shown in the drawings, it is also possible that a hinge member such as a hinge is further provided in a portion where the front portion (10a) and the rear portion (10b) are adjacent to each other.

By using the tilt adjusting means (11) having such a structure, the degree to which the swing plate (10) can be raised by the pinion gear (11c) / rack gear (11d) can be adjusted to the extent that the swing plate (10) can be raised. It is possible to control whether or not it tilts by tilting. The structure of the tilt adjusting means (11) shown in FIG. 4 is an example, and even if a drive source (11a), a shaft member (11b), gears (11c, 11d), etc. are not used, Other configurations for tilting the swing plate (10) can be applied. Further, even when the inclination adjusting means (11) as shown in FIG. 4 is used, it can be transformed into a state different from the state shown in the drawing and used. For example, a plurality of tilt adjusting means (11) can be provided so that the tilt adjusting means (11) can contact a plurality of positions of the swing plate (10), respectively, and in this case, the swing plate (10) can be provided. ), Only part of the plurality of tilt adjusting means (11) may operate, or all tilt adjusting means (11) may operate, and the swing plate (10) may operate in only one direction. It can be tilted or tilted in multiple directions.

Since it is not easy to place and hit a golf ball with the swing plate (10) tilted, a certain level of golf ability is required. Therefore, there may be users who do not like to hit the golf ball with the swing plate (10) tilted. In addition, some users may wish to hit a golf ball with the swing plate (10) tilted, preferring that it is possible to reproduce hitting at a slope in actual golf. In this way, considering that the preference is different for each user, the virtual golf system according to the present embodiment provides a first mode and a second mode that can be selected by the user, and a specific mode thereof is provided. The operation process is as follows.

FIG. 5 is a flowchart showing the operation process of the virtual golf system of FIG.

Referring to FIGS. 1 and 5, the control unit (20) checks the position of the virtual golf ball on the virtual golf course before the user hits, and the first mode and the first mode. The two modes differ in the processing method when the virtual golf ball is located at an inclined point on the virtual golf course. When the virtual golf ball is placed on a flat surface of the virtual golf course, the normal process in the first mode and the second mode (when the user hits the golf ball, the control unit (20) controls the flight trajectory of the golf ball. Is calculated, and an image of a virtual golf ball moving is displayed on the screen (52) based on the calculation result). Therefore, different operating processes in the first and second modes occur in the step (S1) in which the virtual golf ball is located at a slope on the virtual golf course.

In the next step (S2), it is checked whether the current user is a user in the first mode or a user in the second mode. The first and second modes can be set automatically according to the user's level. If you log in before the screen golf service is provided, you can know what kind of user is currently playing from the login information, and refer to the past play record of that user. It is possible to grasp the golf level of the user. For example, when a service provider that provides a screen golf service operates a plurality of screen golf courses and manages the plurality of screen golf courses through a central server connected by a network, the login process for the user is performed by the central server. The central server is equipped with a database for storing personal information and past play records for each user. When the database is provided, the control unit (20), the central server, or the like refers to the database to grasp the golf level of the user, and then automatically sets the user's play mode to the first mode based on the database. Alternatively, it can be set to the second mode.

The first mode is a play mode in which the reality of actual golf is reproduced when hitting a slope, and the difficulty of hitting is high. The second mode is a play mode in which the reality of actual golf is reduced when hitting a slope. It is a play mode with a low hitting difficulty. Therefore, the first mode can be set for a user with a high level of golf, and the second mode can be set for a user with a low level of golf.

The first and second modes can also be selected by the user. Even a beginner may want to play in the first mode in order to experience the reality of actual golf, and even a golf expert may want to play in the second mode according to personal preference. When the user selects a play mode, the play mode can be selected through the input unit (40) before starting golf play. Further, if the user does not select the desired play mode, the play mode can be automatically set.

In the first mode, the steps according to the first mode (S11, S12, S13, S14) are performed, and in the second mode, the steps according to the second mode (S21, S22, S23, S24) are performed.

In the steps (S11, S12, S13, S14) in the first mode, in the first step (S11), the swing plate (10) is adjusted to be tilted at a tilt corresponding to the tilt of the landing point of the virtual golf ball. .. In the second step (S12), the user hits a golf ball placed on the tilted swing plate (10). In the third step (S13), the control unit (20) performs the first method processing such as calculating the trajectory of the golf ball. In the fourth step (S14), a virtual golf ball moving along the calculated trajectory is displayed on the screen (52).

In the steps (S21, S22, S23, S24) in the second mode, in the first step (S21), the swing plate (10) is maintained horizontally regardless of the inclination of the landing point of the virtual golf ball. In the second step (S22), the user hits a golf ball placed on the horizontal swing plate (10). In the third step (S23), the control unit (20) performs the second method processing such as calculating the trajectory of the golf ball. In the fourth step (S24), a virtual golf ball moving along the calculated trajectory is displayed on the screen (52).

Comparing the steps in the first mode (S11, S12, S13, S14) and the steps in the second mode (S21, S22, S23, S24), whether or not the swing plate (10) can be tilted in the first step (S11, S21). The difference is that the control unit (20) performs the first and second methods of processing different from each other for the golf ball hit by the user in the third step (S13, S23). Hereinafter, the first method (FIG. 6) and the second method (FIGS. 7 to 11) will be described in detail with reference to the drawings.

FIG. 6 shows the principle of calculating the trajectory of a golf ball in the first mode.

Referring to FIG. 6, in the first method, the control unit calculates the trajectory of the golf ball (B) based on the physical state of the golf ball (B) hit by the user. The physical state of the golf ball (B) is sensed by the sensing unit. Specifically, various physical parameter values indicating the physical state of the golf ball (B) are grasped. The types of physical parameters are extremely diverse, and the actual movement of the hit golf ball (B) also fluctuates from time to time. Therefore, when calculating the trajectory in consideration of all of these, The calculation process becomes very complicated. Therefore, for convenience of explanation, the trajectory of the golf ball (B) is calculated by a simple model using only a part (for example, the moving speed and the moving direction of the golf ball) among various physical parameters of the golf ball (B). Explain the process.

As illustrated in FIG. 6, when the user hits the golf ball (B), the golf ball (B) flies at a predetermined speed (V1) and direction (θ1). Here, the velocity (V1) is the initial velocity immediately after the golf ball (B) is hit, and the direction (θ1) is an angle tilted with respect to the horizontal plane as a factor indicating the direction of flight by the hit. The control unit calculates what kind of trajectory (T1) the golf ball (B) has when it moves with the physical parameters (V1, θ1). After extracting the parameters indicating the physical properties of the golf ball (B) in this way, the process according to the first method is to calculate the locus (T1) by using the parameters as they are. In short, the actual golf ball (B) hit by the user is used as it is without changing the physical state. In the first mode, the swing plate is also hit in an inclined state so that the situation where the virtual golf ball is located at the inclined point can be reproduced as it is. Hereinafter, "screen conditions") and "conditions on which an actual golf ball is placed on a swing plate (hereinafter referred to as" plate conditions ")" correspond to each other, and the first method is as follows. When both conditions are met, the method used in normal screen golf is used as it is for hitting (hereinafter referred to as "normal hitting").

In contrast, in the second mode, the swing plate hits in a horizontal state (hereinafter referred to as "abnormal hit") even though the virtual golf ball is located at the inclined point, which is a screen condition. Since the conditions of the plate and the plate do not correspond to each other, when both conditions do not correspond to each other, it is the second method to apply a method different from the method used in ordinary screen golf. Specifically, the second method can give a predetermined disadvantage such as giving a penalty point to a user who makes an abnormal hit or reducing the flight distance.

7 shows various examples of giving penalty points in the second mode, FIGS. 8 and 9 show various examples of using the penalty points to give a disadvantage to the user, and FIGS. 10 and 11 show various examples of giving a penalty point in the second mode. The principle of calculating the trajectory of a golf ball is shown.

Referring to FIG. 7, in the second mode, the user can be given a penalty point in various ways by the second method. As shown in FIG. 7, penalty points can be given by various methods such as the first method (A), the second method (B), and the third method (C).

The first method (A) of giving penalty points is to calculate the number of abnormal hits and the penalty points on a one-to-one basis and give one penalty point each time there is an abnormal hit. The penalty points illustrated in the table of FIG. 7 mean the total up to the time when the penalty points occur. Therefore, in the first method (A), one penalty point is generated for each abnormal hit, one total penalty point up to now is shown in the table, and another penalty point is one for two abnormal hits. Points have been generated, and the total penalty points up to now are listed in the table.

The second method (B) gives a penalty point based on a kind of weighted value, and as shown in FIG. 7, the penalty point score increases as the number of abnormal hits increases. It is a thing. For example, 0.2 penalty points are generated for each abnormal hit (total score 0.2), 0.3 penalty points are generated for 2 abnormal hits (total score 0.2 + 0.3 = 0.5), and 3 abnormal hits. This is a method in which 0.5 penalty points are generated (total points 0.2 + 0.3 + 0.5 = 1), and higher penalty points are given as the number of abnormal hits increases.

The third method (C) checks under what circumstances the penalty points are generated, and the penalty points given by each situation change. For example, if the inclination of the point where the virtual golf ball is located is low (for example, if the inclination is less than or equal to a predetermined inclination) during the first abnormal hit and the second abnormal hit, a penalty of 0.5 points is provided for each. If points are given and the inclination of the point where the virtual golf ball is located is high (for example, if the inclination is equal to or higher than the predetermined inclination) at the time of the third, fourth, and fifth abnormal hits, one penalty point is given for each. give. As a result, as shown in FIG. 7, the total penalty points are 1 (0.5 + 0.5) at the time of the second abnormal hit, and the total points of the penalty points are 2 (0.5) at the time of the third abnormal hit. +0.5 + 1), the total penalty points for the 4th abnormal hit is 3 (0.5 + 0.5 + 1 + 1), and the total penalty points for the 5th abnormal hit is 4 (0.5 + 1). +0.5 + 1 + 1 + 1).

FIG. 7 only shows a number of examples of giving penalty points, and the method of giving penalty points is not limited to the method shown in FIG. 7, and a wide variety of other methods can be applied.

Although giving penalty points as described above is for giving a predetermined disadvantage to the user, it cannot be said that the user is substantially disadvantaged simply by having the penalty points. .. In the following, we will look at some examples (see (1)-(4) below) among the various ways in which penalty points can be used to substantially penalize users.

(1) Penalty points can be used to give penalties to users. Penalties are given in various cases such as touching a golf ball while making a practice swing or hitting the body in golf, but even in screen golf, penalty points are converted into penalties. By doing so, it is possible to give a disadvantage to the user. Various methods can also be applied to convert penalty points into penalties. For example, as shown in FIG. 8, the value of the penalty point and the penalty stroke is calculated in a one-to-one manner, and one penalty stroke is given every time the total score of the penalty points becomes a natural number. (See the "D" part in the table in Figure 8), or calculate the penalty points and penalties to be 2: 1 and 1 each time the total penalty points are doubled. Penalties can be granted (see part "E" in the table of FIG. 8).

(2) Penalty points can be used to deprive users of the opportunity to mulligan. Mulligan means that when a big miss shot occurs, it gives you the opportunity to cancel it and take another shot. Normally, a user of screen golf sets and plays the number of mulligans given to each user before the start of screen golf. For example, if the mulligan is set to 3 times, each user can cancel the 3 worst shots while playing. Taking away the opportunity of such a mulligan is disadvantageous to the user, so one way to use the penalty points is to reduce the number of times the mulligan is used. As for how to convert penalty points to reduce the chance of mulligan, the same method as the method for converting penalties can be applied, or other methods can be applied. .. For example, as shown in FIG. 8, each time the total number of penalty points becomes a natural number, the mulligan is taken once (see the "D" part in the table of FIG. 8), or the penalty is taken. Each time the total points are doubled, you can take the opportunity of the mulligan once (see the "E" part in the table in Figure 8).

FIG. 8 only shows a number of examples in which penalty points can be converted into penalties or deprivation of mulligan opportunities, and a wide variety of other conversion methods not shown herein can be applied.

(3) Penalty for points can be used to reduce the range of distances recognized as concedes. Conceed means that if the putt golf ball is within a certain distance from the hole cup, it is recognized that the hole in has been successful. Normally, screen golf users set and play a range of conceeds before starting screen golf. For example, when the concede is set to 1.5 m, a golf ball located within a radius of 1.5 m from the hole cup is regarded as a hole-in. If the conceed range is reduced, the user must put as close to the hole cup as possible in order to successfully hole in. Therefore, reducing the distance accepted as a concede is disadvantageous to the user, and one way to utilize the penalty points is to reduce the concede distance. Specifically, as shown in FIG. 9, when the concede is set to 1.5 m, the concede is set to 1 m when the penalty point is 1 point, and when the penalty point is 2 points. The concede can be 0.5 m. However, FIG. 9 shows only one example of converting a penalty point into a reduction in concealed distance, and a wide variety of other conversion methods not shown herein can be applied.

(4) When there is a penalty point, it is possible to prevent various information provided for the convenience of the user from being provided. In screen golf, the golf course displayed on the screen often reflects the golf course of an actual golf course as it is. For example, if the golf course of an actual golf course has a slope in the vicinity of the hole cup or the height is not constant, the golf course on the screen also has a slope in the vicinity of the hole cup or the height is not constant. It is composed of. In this case, if the inclination and the change in height are not taken into consideration when putting, it becomes difficult to succeed in putting. However, it is very difficult for the user to grasp the inclination and height of the area near the hole cup and put it properly only by the image displayed on the screen, so in screen golf, a virtual caddy appears on the screen and the golf ball Appropriate advice can be provided by considering the position and the inclination and elevation of the area near the hole cup (for example, presenting the putting direction such as "putting at an angle of about 20 degrees to the left"). Since it is difficult to succeed in putting without such advice, it is disadvantageous to the user not to provide the above advice. Therefore, one way to use the penalty points is to think of not providing various information and advice necessary for putting and shots.

(1)-(4) explained how to use penalty points to disadvantage users with abnormal hits, but (1)-(4) is one of the various methods that can be disadvantageous. There are only a few examples, and a great variety of other methods not described here can be applied.

Further, the methods (1)-(4) can be applied independently, or a plurality of methods can be combined and applied. For example, when the penalty point is small, the mulligan opportunity is taken based on the method (2), and the penalty point is more than a predetermined value, or the user already uses a part or all of the mulligan and takes more mulligan opportunity. If there is no remaining, it is possible not to provide various information and advice to the user based on the method (4).

Further, although it is possible to give a disadvantage to all users who have a penalty point in the same manner, it is also possible to give a disadvantage to each user in a different manner. For example, when a plurality of users select a second mode before starting playing screen golf, the disadvantageous method desired by each of the plurality of users who have selected the second mode is preset by themselves. You can punish users and deprive other users of mulligan opportunities.

On the other hand, it is not necessary to handle the penalty points so that a disadvantage always occurs. That is, the screen golf system does not determine that a specific disadvantage occurs based on the penalty points as in (1)-(4), and the user decides which penalty point by himself after completing the screen golf. You can also decide what to do with it. If a user who plays screen golf together grants another user an abnormal hit, it is possible to agree that the other user will not be disadvantaged even if he / she has a penalty point. Alternatively, even if the screen golf system does not cause any penalty points disadvantage, the penalty is paid by the user who played the screen golf together and the person with the highest penalty point to pay the cost of the screen golf. It is possible to create an economic disadvantage to the points.

As described above, a penalty point can be given to a user who makes an abnormal hit based on the second method in the second mode. When a penalty point is given, the flight distance can be calculated by the same method as in the first mode because the penalty point has already been disadvantaged. On the other hand, as explained below, it is possible to change the method of calculating the trajectory of the golf ball without giving a penalty point so that a predetermined disadvantage occurs (or while giving a penalty point). At the same time, as explained below, the flight distance can be calculated and the disadvantage can be further increased.)

Specifically, after calculating the flight distance of the golf ball under the second mode, the flight distance can be artificially reduced by the second method. With reference to FIG. 10, first, the locus of the golf ball is calculated in the same manner as in the case of the first method. That is, when the golf ball (B) hit by the user has a predetermined velocity (V1) and direction (θ1), the control unit determines that the golf ball (B) has the above physical parameters (V1, θ1). Calculate what kind of trajectory (T1) you have when you exercise with it. After calculating the locus (T1) in this way, the flight distance of the golf ball (B) is artificially reduced by a predetermined distance (d). The amount of decrease in flight distance can be set to be proportional to the degree of inclination of the point where the virtual golf ball is located on the screen. Generally, if the degree of inclination is large, the difficulty of hitting can be considered to be high, and it can be said that the flight distance decreases as the degree of difficulty of hitting increases, so that the amount of decrease in the flight distance increases along the degree of inclination. Can be set as. The above-mentioned reduction in flight distance can be set so that a predetermined numerical value decreases based on the degree of inclination (eg, 5 m, 10 m, 15 m, etc.), or is specific for the flight distance calculated based on the degree of inclination. It can be set to reduce the flight distance of the ratio (eg 5%, 10%, 15%, etc.).

In this way, the second method is to extract the parameters indicating the physical properties of the golf ball (B), calculate the trajectory (T1) using the parameters as they are, and then artificially reduce the flight distance. ..

Alternatively, instead of reducing the flight distance, a method of changing the parameter indicating the physical properties of the golf ball (B) by another method can be applied. Referring to FIG. 11, when the golf ball (B) hit by the user has a predetermined velocity (V1) and direction (θ1), the first locus (T1) is taken from the physical parameters (V1, θ1). Is calculated, in this method, the locus is calculated after partially transforming a part of the physical parameters, reflecting the inclination of the point where the virtual golf ball of the screen (52) is placed. .. For example, if the vertical angle between the horizontal plane and the moving golf ball in the sensed physical state of the golf ball is "θ1", and the inclination of the point where the virtual golf ball is placed is "α". Using "θ1, α", the direction value of the physical parameter of the golf ball is deformed and the deformation value "θ2" is calculated as follows.
θ2 = f (θ1, α)

As described above, when the deformation value "θ2" is calculated from the first direction value (θ1), the locus (T2) is calculated from the velocity (V1) and the deformation value (θ2). Here, "f (θ1, α)" is a function or mathematical formula having θ1, α as variables, and is the simplest form.
f (θ1, α) = θ1 + α
Can be.

Alternatively, set a predetermined weighted value (β) to the extent that it reflects the degree of inclination,
f (θ1, α) = θ1 + α × β
Can be.

Or, through various experiments, you can create and apply complex mathematical formulas that are relevant to the actual situation.

In this way, the second method is to extract the parameters indicating the physical properties of the golf ball (B), artificially deform some of the parameters, and then calculate the trajectory (T2) based on this. be.

As mentioned above, in the second mode, in order to give a disadvantage to the hit (abnormal hit) in the state where the screen condition and the plate condition do not match, the trajectory of the golf ball has the screen condition and the plate condition. A method is applied in which a penalty point is given while calculating in the same way as in the case of a hit in a matched state (normal hit), or a method of adjusting the flight distance by a method different from that in the case of a normal hit is applied instead of giving no penalty point. Can be done. However, the method presented here is only an example of shoes, and there may be various other methods that can be applied to the second mode.

In addition, although various processing methods of the second mode for giving a disadvantage to the abnormal hitting compared to the normal hitting have been described so far, it is necessary to be processed so as to give a disadvantage to the user as the second mode. not. The purpose of playing screen golf is different for each user, and from the standpoint of users who enjoy screen golf simply for entertainment purposes to relieve stress, they play while hitting abnormally in the second mode. You may want to avoid another disadvantage. Therefore, only normal hitting is effective in the first mode, and only abnormal hitting is effective in the second mode, but while calculating the flight distance of the golf ball in the first and second modes by the same method. It can also be configured so as not to disadvantage the user in the second mode.
