Description

Virtual golf system with sloped swing plate {VIRTUAL GOLF SYSTEM WITH SLANTED SWING PLATE}

The present invention relates to a virtual golf system, and more particularly, to a virtual golf system having a swing plate that can be inclined at a predetermined angle.

Simulation devices for enjoying sports games without going to the field have been developed using 3D stereoscopic images and computer simulation technology, and virtual indoor sports games such as golf or baseball have been widely spread. In the case of screen golf, which is a representative indoor sport, video of the golf course is displayed through the screen, giving the impression that you are playing a real golf game outdoors, while saving time and money compared to playing on an outdoor field. It is very popular with modern people who have difficulty playing golf due to time or economic reasons.

There are various terrains such as fairways, rough, bunkers, water hazards, etc. on the golf course of actual golf, and these terrains are flat or inclined, so depending on the properties of these terrains, the feeling of hitting the golf ball by the user Or hitting difficulty is different. For example, when hitting on inclined terrain compared to hitting on flat ground, the feeling of hitting is different and the hitting difficulty increases. In contrast, since the swing plate for hitting a golf ball on a screen golf course is usually installed on a flat floor, it is difficult to reproduce the feeling of hitting a golf ball at an inclined point of actual golf.

In consideration of the above points, there may be another problem when the swing plate is formed in an inclined manner. That is, some users may like it because they can reproduce the feeling of hitting at an inclined point, but other users may oppose it because they think that it is uncomfortable to hit the inclined swing plate due to their lack of golf skills. Accordingly, there is a need to develop a system capable of satisfying the needs of various users while providing reality as if playing golf in real life.

The present invention was invented in view of the above circumstances, and an object of the present invention is to provide a virtual golf system capable of satisfying the needs of various users while providing the reality of actual golf by providing a swing plate that can be inclined.

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

A virtual golf system according to an embodiment of the present invention includes a swing plate on which a golf ball is placed and which can be inclined, and a display unit showing an image of a virtual golf course and a virtual golf ball. In the virtual golf system, the user can play in different first and second modes. In addition, when the position where the virtual golf ball is placed on the virtual golf course is an inclined point before the user strikes the golf ball, in the first mode, the user is effectively in a state in which the swing plate is inclined at a predetermined angle. The golf ball can be hit, and in the second mode, the user can effectively hit the golf ball while the swing plate is not inclined.

The virtual golf system further includes an inclination adjusting means for adjusting the swing plate to be inclined at a predetermined inclination angle, and when the position where the virtual golf ball is placed on the virtual golf course is an inclined point, corresponding to the inclination of the inclined point The inclination angle of the swing plate may be adjusted by the inclination adjusting means so that it is possible.

In the virtual golf system, the user may preselect any one of the first and second modes before starting play. Here, when there are a plurality of users, the display unit displays a screen on which an image of the virtual golf course and the virtual golf ball is displayed to a plurality of users, and displays a window for each of the plurality of users on the screen, and Each of the windows may display a play mode selected by each user.

The virtual golf system further includes a control unit for calculating a trajectory of the hit golf ball when the user strikes the golf ball, and when the trajectory of the golf ball is calculated, the display unit moves the virtual golf ball according to the calculated trajectory. You can show an image of a golf ball.

In the virtual golf system, the controller calculates the trajectory based on the physical state of the hit golf ball, and under the second mode, the virtual golf ball is placed on a slope and the swing plate is not inclined. Penalty points can be imposed on the hitting user. Here, the penalty point may be increased according to the number of hits while the virtual golf ball is placed on an inclined point and the swing plate is not inclined under the second mode. In addition, the penalty point may be converted to a penalty point, converted to reduce the number of mulligans granted to the user, or converted to reduce a concede range.

In the virtual golf system, the control unit calculates the trajectory based on the physical state of the hit golf ball under the first mode, and calculates the trajectory based on the physical state of the hit golf ball under the second mode. After calculating, the calculated flying distance may be reduced by a predetermined distance. Here, the amount of reduction for reducing the calculated flying distance may vary according to the inclination angle of the inclined point on which the virtual golf ball is placed.

In the virtual golf system, the controller calculates the trajectory based on the physical state of the hit golf ball under the first mode, and determines the physical state of the hit golf ball under the second mode. After deforming by reflecting the inclination angle of the placed inclined point, the trajectory may be 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 inclined, there is an effect of providing the reality of actual golf and at the same time satisfying the needs of various users.

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 hitting zone in which a golf ball is placed and a hit is made, and in particular, the swing plate 10 according to the present embodiment may be inclined at a predetermined angle. This is because the inclination adjusting means (see reference numeral 11 in FIG. 3) for adjusting the swing plate 10 to be inclined at a predetermined inclination angle is provided, which will be described later.

The controller 20 controls the overall operation of each component in screen golf. For example, the control unit 20 may control the inclination adjustment means to control whether the swing plate 10 remains horizontal or at a certain angle to be inclined. In addition, when the user strikes a golf ball placed on the swing plate 10, the control unit 20 may calculate the trajectory of the hit golf ball to fly.

The detection unit 30 checks the state of the swing plate 10 on which the golf ball to be hit by the user is placed, or detects overall status information on the golf ball hit by the user. When the state information of the golf ball hit by the user is detected by the detection unit 30, the result is transmitted to the control unit 20, which calculates the trajectory of the golf ball hit by the user to fly. When doing so, it is used as evidence. As the sensing unit 30, any sensing means such as a camera capable of photographing the movement of a golf ball or a detection sensor capable of detecting the movement of a golf ball may be used. The camera or detection sensor may be used alone or together, and only one may be used, or several may be used as necessary.

The input unit 40 is for receiving various types of information from a user, and a keyboard or mouse may be used. In screen golf, there are cases where information input from the user is required, such as when a user enters his or her ID or password for login, or when the user selects a golf course or difficulty level to play, etc., for this purpose, the input unit ( 40) is provided. The information input by 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 controller 20 performs necessary processing so that the user can play on the golf course. Specifically, the controller 20 includes an image processing means for processing an image, so that when a user selects a specific golf course, the image processing means transmits the corresponding golf course image to the display unit 50 to be displayed. have. In addition, when a user inputs personal information such as a child or a password for login, the controller 20 may play a role of determining whether to approve the login by checking the input personal information. Alternatively, a service provider providing a screen golf service may operate a plurality of screen golf courses. In this case, the plurality of screen golf courses are managed by a central server connected through a network, and the login process may be performed by the central server.

The display unit 50 includes a beam projector 51 and a screen 52. The beam projector 51 projects a related image on the screen 51 so that the virtual golf course and the virtual golf ball are displayed on the screen 52, and the screen 52 plays a role of displaying a golf related image to the user. . For reference, in this specification, an object displayed on the screen 52 may be expressed by attaching 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' is a screen. It means that it is a golf ball displayed at (52).

Although not shown in FIG. 1, a voice processing unit may be provided to inform the user of the progress of the game and reproduce various sound effects according to the progress of the game.

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

2, a virtual golf course is displayed on the screen 52, and the virtual golf course reflects the actual golf course. In actual golf, after the first tee shot, the hit golf ball flies and lands at a specific point, and afterwards, the hit continues at the landed point. Even in the virtual golf system of the present invention, after taking a tee shot from the swing plate 10, the detection unit 30 detects the state of the hit golf ball and transmits it to the control unit 20, and the control unit 20 is based on the detection result. Thus, the flight trajectory is calculated assuming that the golf ball is flying in an actual golf course in a state sensed by the detection unit 30. Depending on the calculated result, a moving image of a virtual golf ball (VB) is displayed on the screen 52, and the virtual golf ball (VB) flies according to the calculated result, and then the virtual golf ball in the screen 52 It lands at a specific point on the course, and the user continues to hit at the point where the virtual golf ball (VB) lands.

However, in actual golf, the point at which the golf ball lands may be a terrain having various properties such as fairway, rough, and bunker, and various properties such as virtual fairway, virtual rough, and virtual bunker are also applied to the virtual golf course of the screen 52. The terrain you have can be displayed. In addition, in actual golf, the point at which the golf ball lands may be a horizontal or inclined point, and the virtual golf course in the screen 52 also reflects this point. That is, as shown in Fig. 2(a), the virtual golf ball (VB) can be located at a horizontal point of the virtual golf course, and as shown in Fig. 2(b), the virtual golf ball (VB) is virtual It can be located on an inclined point on a golf course.

In actual golf, if the landing point is a horizontal or inclined point, when hitting at this landing point, the golf ball strikes in a horizontal state or strikes in an inclined state. However, in the conventional screen golf course, since the swing plate on which the hitting golf ball is placed is always in a horizontal state, there is a problem that it is difficult to experience the hitting feeling at an inclined point. However, 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 may be inclined at a predetermined angle by the inclination adjusting means 11. Therefore, when the virtual golf ball VB of the screen 52 lands on a horizontal point (see Fig. 2(a)), the swing plate 10 maintains a horizontal state as shown in Fig. 3(a). , When the virtual golf ball VB of the screen 52 lands on an inclined point (see Fig. 2(b)), the swing plate 10 is inclined at a predetermined angle as shown in Fig. 3(b). . At this time, the angle of inclination of the swing plate 10 may be adjusted to correspond to the degree of inclination of the point where the virtual golf ball VB in the screen 52 lands. For example, when the inclination angle of the point where the virtual golf ball (VB) lands is 5°, 10°, and 15°, respectively, the inclination angle of the swing plate 10 is the same as the inclination of the inclined point 5°, 10°, respectively. It can be adjusted to be °, 15°. Alternatively, when the inclination angle of the point where the virtual golf ball (VB) lands is 5°, 10°, 15°, the inclination angle of the swing plate 10 is 2.5°, 5° in proportion to the inclination of the inclined point, It can be adjusted to 7.5° or 10°, 20° or 30°. Alternatively, in another manner not mentioned herein, the inclination of the point where the virtual golf ball VB lands and the inclination angle of the swing plate 10 may be configured to correspond. Adjusting the inclination of the point where the virtual golf ball VB lands and the inclination angle of the swing plate 10 correspond to each other may be performed by the controller 20. Since the control unit 20 calculates the trajectory of the hit golf ball, it is possible to calculate the landing position of the virtual golf ball VB, and accordingly, the slope at that position can be grasped from the landing position determined accordingly. The controller 20 determines the inclination of the landing position and controls the inclination adjusting means 11 provided on the swing plate 10 to have an inclination angle corresponding to the inclination. Accordingly, the swing plate 10 may be inclined to have an inclination angle corresponding to the inclination of the point where the virtual golf ball VB lands.

Referring to FIG. 4, the inclination adjusting means 11 may include a driving source 11a, a shaft member 11b, and gears 11c and 11d. A shaft member 11b is coupled to the drive source 11a, and gears 11c and 11d are mounted to the shaft member 11b. A motor may be used as the drive source 11a, and when the drive source 11a operates, the shaft member 11b coupled to the drive source 11a rotates. As the gears 11c and 11d, a pinion gear 11c and a rack gear 11d capable of converting rotational motion into linear motion may be used, and when the shaft member 11b rotates, the gears 11c and 11d are operated. The rotational motion is converted into a linear motion, so that 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, and the rack gear 11d is in contact with the swing plate 10 as the rack gear 11d moves up and down. The corresponding part of the can be lifted upwards or lowered downwards. The swing plate 10 may be divided into a front portion 10a and a rear portion 10b positioned in front and rear, respectively, based on an intermediate portion to which the rack gear 11d contacts. When the swing plate 10 is lifted upward, the front portion 10a is inclined toward the front and the rear portion 10b is inclined toward the rear. Although not shown in the drawings, a hinge member such as a hinge may be further provided at a portion adjacent to the front portion 10a and the rear portion 10b.

Using the inclination adjusting means 11 having such a structure, the swing plate 10 is adjusted to a certain degree of inclination by adjusting the degree to which the swing plate 10 is lifted by the pinion gear 11c/rack gear 11d. You can control whether or not it will be inclined. Here, the structure of the inclination adjusting means 11 shown in FIG. 4 is only an example, and even if the driving source 11a, the shaft member 11b, the gears 11c, 11d, etc. are not used, the swing plate 10 Other configurations for obliquely may be applied. In addition, even in the case of using the inclination adjusting means 11 as shown in Figure 4, it can be used by modifying it differently from the state shown in the drawing. For example, a plurality of inclination adjustment means 11 may be provided so that the inclination adjustment means 11 is in contact with each of the various positions of the swing plate 10, and in this case, when the swing plate 10 is inclined, a plurality of Only some or all of the inclination adjusting means 11 are operated so that the swing plate 10 is inclined in only one direction or in several directions.

Since it is not easy to hit the golf ball while the swing plate 10 is inclined, a certain level of golf skill is required. Therefore, some of the users may not prefer to hit the golf ball while the swing plate 10 is inclined. In addition, there may be users who prefer to be able to reproduce the hitting at an inclined point in actual golf, and prefer to hit the golf ball while the swing plate 10 is inclined. In view of the fact that preference may be different for each user as described above, the virtual golf system according to the present embodiment provides a first mode and a second mode that the user can select, and a specific operation process according to this is as follows.

5 is a flowchart illustrating an operation process in the virtual golf system of FIG. 1.

1 and 5, the controller 20 detects where the virtual golf ball is placed on the virtual golf course before the user strikes. In the first mode and the second mode, the virtual golf ball is virtual golf. When placed on an inclined point on the course, a difference occurs in the processing method, and when the virtual golf ball is placed on a flat point on the virtual golf course, the normal process (when the user strikes the golf ball, the control unit 20 The flight trajectory of is calculated, and an image of moving a virtual golf ball is displayed on the screen 52 according to the calculated result). Accordingly, different operation processes in the first and second modes are initiated in step S1 in which the virtual golf ball is positioned at an inclined point of the virtual golf course.

In the next step (S2), it is checked whether the current user is the user of the first mode or the user of the second mode. The first and second modes may be automatically set according to the user's level. If a login is made before the screen golf service is provided, it is possible to determine which user is currently playing from the login information, and the user's golf level can be determined by referring to the user's past play record. For example, when a service provider providing a screen golf service operates a plurality of screen golf courses and manages the plurality of screen golf courses in a central server that connects the plurality of screen golf courses through a network, the log-in process for the user is performed by the central server. The central server may be provided with a database storing personal information and past play records for each user. When the database is provided, the control unit 20 or the central server may check the user's golf level by referring to the database, and then automatically set the user's play mode to the first mode or the second mode based on this. .

The first mode is a play mode that reproduces the reality of golf when hitting an inclined point, and the second mode is a play mode with a low hitting difficulty because the reality of the actual golf is reduced when hitting an inclined point. . Accordingly, a first mode may be set for a user with a high golf level, and a second mode may be set for a user with a low golf level.

The first and second modes may be selected by the user himself. Even beginners may want to play in the first mode in order to make use of the reality of real golf, and even a golf expert may want to play in the second mode according to their personal preference. When the user selects the play mode, the play mode may be input through the input unit 40 before starting golf play. In addition, when the user does not select a desired play mode, the play mode can be automatically set.

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

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

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

Comparing the steps according to the first mode (S11, S12, S13, S14) and the steps according to the second mode (S21, S22, S23, S24), the swing plate 10 in the first step (S11, S21) There is a difference depending on whether or not it is inclined, and there is a difference in that the control unit 20 processes the golf ball hit by the user in the third step (S13, S23) in different first and second methods. Hereinafter, the first method (FIG. 6) and the second method (FIG. 7 to FIG. 11) will be described in detail with reference to the drawings.

6 is a diagram showing a principle of calculating a trajectory of a golf ball in a first mode.

Referring to FIG. 6, in the first method, the controller calculates what trajectory the golf ball B will fly 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, and in detail, values of various physical parameters representing the physical state of the golf ball (B) are determined. Since the types of physical parameters are very diverse, and the movement of the hitting actual golf ball B changes from time to time, the calculation process becomes very complicated when the trajectory is calculated in consideration of all of them. Therefore, for convenience of explanation, a process of calculating the trajectory of the golf ball B will be described in a very simplified manner using only some of the various physical parameters for the golf ball B (for example, the moving speed and the moving direction of the golf ball).

As shown in Figure 6, when the user hits the golf ball (B), the golf ball (B) flies with a predetermined speed (V1) and direction (θ1). Here, the speed V1 may be the initial speed immediately after the golf ball is hit, and the direction θ1 may be an angle inclined with respect to the horizontal plane as a factor indicating the direction in which the golf ball is blown. The control unit calculates what trajectory T1 has when the golf ball B moves with the physical parameters V1 and θ1 described above. In this way, after extracting a parameter representing the physical properties of the golf ball B, the trajectory T1 is calculated by using the parameter as it is, according to the first method. In short, it is used as it is without changing the state of the actual golf ball B hit by the user, which is a method commonly used in general screen golf. The first mode is to hit the swing plate in an inclined state so that the situation in which the virtual golf ball is located at the inclined point can be reproduced as it is. ")" and "the condition in which the actual golf ball is placed on the swing plate (hereinafter referred to as'plate condition')" correspond to each other, and the first method corresponds to the blow when both conditions correspond (hereinafter, In the'normal hitting'), the method used in general screen golf is followed as it is.

In contrast, the second mode is to hit the swing plate in a horizontal state (hereinafter referred to as'abnormal hitting') even though the virtual golf ball is located at the inclined point, so the screen condition and the plate condition do not correspond to each other. If the two conditions do not correspond as described above, the second method is to apply a method different from the method used in the conventional screen golf. Specifically, the second method may impose a penalty point on a user who makes an abnormal hit or may give a predetermined disadvantage such as a reduction in flying distance.

7 is a diagram showing various examples of imposing a penalty point in a second mode, FIGS. 8 and 9 are diagrams showing various examples of penalizing a user by using a penalty point, and FIGS. 10 and 11 are a second mode It is a diagram showing the principle of calculating the trajectory of a golf ball.

Referring to FIG. 7, penalty points may be imposed on the user in various ways by the second method under the second mode. As shown in FIG. 7, penalty points can be imposed in various ways, such as the first method (A), the second method (B), and the third method (C).

The first method (A) of imposing penalty points is to calculate the number of abnormal hits and penalty points on a one-to-one basis, and impose a penalty point by one point each time an abnormal hit occurs. For reference, the penalty points shown in the table of FIG. 7 refer to the total sum up to the point when the penalty points occur. Therefore, in the first method (A), one penalty point is generated for one abnormal blow, and the total number of penalty points so far is listed in the table, and for two abnormal blows, one penalty point is generated. Two total penalty points are listed in the table.

The second method (B) is to impose penalty points according to a kind of weight, and as shown in FIG. 7, as the number of abnormal hits increases, the penalty point score is also increased. For example, for one abnormal blow, a penalty point of 0.2 points (total point 0.2), for two abnormal blows, a penalty point of 0.3 points (total point 0.2+0.3=0.5), and for three abnormal blows, a penalty point of 0.5 points occurs. In the (total score 0.2+0.3+0.5=1) method, the higher the number of abnormal hits, the higher the penalty point is imposed.

The third method (C) is to check in which situation the penalty point has occurred, and to impose the penalty point differently according to each situation. For example, if the inclination of the point where the virtual golf ball is positioned is low (e.g., if it is less than a predetermined slope) during the first and second abnormal hits, a penalty point of 0.5 points is imposed, and the third, fourth, and fifth abnormal hits are made for virtual golf. When the inclination of the point where the ball is located is high (for example, when the inclination exceeds a predetermined inclination), a penalty point of 1 is imposed on each. As a result, as shown in FIG. 7, the total score of the penalty point for the second abnormal hit is 1 (0.5+0.5), the total score of the penalty point for the third abnormal hit is 2 (0.5+0.5+1), and the fourth When hitting abnormally, the total score of penalty points is 3 (0.5+0.5+1+1), and when hitting the fifth abnormal hit, the total score of penalty points is 4 (0.5+0.5+1+1+1).

FIG. 7 is only showing some examples of imposing penalty points, and the method of imposing penalty points is not limited to the method illustrated in FIG. 7, and a wide variety of other methods may be applied.

As described above, the imposition of penalty points is intended to give a predetermined disadvantage to the user, but the fact that there is a penalty point cannot be regarded as a real disadvantage to the user. Hereinafter, some examples (refer to (1) to (4) below) of various methods that can substantially disadvantage a user by using a penalty point will be described.

(1) Penalty can be given to the user using penalty points. Penalty is originally a practice swing in golf, but may be given in various cases such as hitting a golf ball or hitting a golf ball. In screen golf, penalty points can be converted into penalties, thereby penalizing the user. Various methods can also be applied to convert penalty points into penalty points. As shown in FIG. 8, when the total number of penalty points becomes a natural value by simply calculating the values of penalty points and penalty strokes as one-to-one. One penalty stroke is given each time (refer to the'D' part in the table in Fig. 8), or the value of the penalty point and the penalty stroke is calculated as 2 to 1, and 1 penalty stroke is awarded whenever the total score of the penalty points becomes a multiple of 2. It can be given (refer to the'E' part in the table of FIG. 8).

(2) Penalty points can be used to deprive the user of the chance of a mulligan. Mulligan means that when a shot is seriously wrong, it is canceled and given so that the shot can be taken again. Normally, screen golf users set and play the number of mulligans given to each user before starting. For example, if Mulligan is set to 3, each user can cancel 3 worst shots while playing. Since depriving the opportunity of such a mulligan is disadvantageous to the user, it is conceivable to reduce the number of times of use of the mulligan by using a penalty point. As for how to convert the penalty points to reduce the chance of mulligan, the same method as the method of converting penalty points may be applied, or a different method may be applied. For example, as shown in FIG. 8, each time the total score of the penalty points becomes a natural value, the chance of mulligan is deprived once (refer to the'D' part in the table of FIG. 8) or the total score of the penalty points is 2 Whenever the multiple value is reached, the chance of the mulligan can be deprived once (refer to the'E' part in the table of FIG. 8).

8 is only showing some examples of converting a penalty point into a penalty point or deprivation of a mulligan opportunity, and a wide variety of conversion methods not shown here may be applied.

(3) Penalty points can be used to reduce the range of distance recognized as concede. Conseed means that if the putt golf ball is within a certain distance from the hole cup, it is recognized as a hole in. Typically, screen golf users set the concealed range and play before starting. For example, if the concid is set to 1.5m, a golf ball located within a radius of 1.5m from the hole cup is regarded as hole-in. If the concealed range is reduced, the user must putt as close as possible to the hole cup in order to recognize the hole-in. Therefore, decreasing the distance recognized as consid is disadvantageous to the user. Therefore, it is possible to consider reducing the consid distance by using a penalty point. Specifically, as shown in FIG. 9, when the consid is set to 1.5m, the conceal may be 1m when the penalty point is 1, and the consid may be 0.5m when the penalty point is 2. However, FIG. 9 shows only one example of converting a penalty point into a reduction in consid distance, and a wide variety of conversion methods not shown here may be applied.

(4) When there is a penalty point, various information provided for the user's convenience can be prevented from being provided. In screen golf, the golf course displayed on the screen is often represented by reflecting the actual golf course of the golf course. For example, in a golf course of an actual golf course, when the inclination or height is not constant in the area near the hole cup, the inclination or height in the area near the hole cup is not uniform in the golf course of the screen. In this case, it is difficult to succeed in putting if the change in the slope or height is not taken into account when putting. However, since it is very difficult for the user to determine the slope or height of the area near the hole cup with only the image displayed on the screen and put it correctly, in screen golf, a virtual caddy appears on the screen and the position of the golf ball and the slope of the area near the hole cup You can provide appropriate advice considering the height (for example, suggesting the putting direction, such as "Put at an angle of about 20 degrees to the left"). Since it is difficult to succeed in putting without such advice, not providing the advice may be disadvantageous to the user. Therefore, as a method of using penalty points, you can consider not providing useful information or advice for putting or shots.

In (1)-(4), the method of penalizing the user of the abnormal hit using the penalty point was explained, but (1)-(4) are only a few examples of various methods that can give a disadvantage, and explained here A wide variety of other methods may be applied that do not.

In addition, the methods (1)-(4) can be applied independently, but may be applied in combination with other methods. For example, when the penalty point is small, the chance of the mulligan is deprived according to the method in (2), the penalty point is more than a predetermined value, or the user has already used some or all of the mulligan and the opportunity of the mulligan to be deprived any more. When is not left, it can be made not to provide various information or advice to the user according to the method of (4).

In addition, a user with penalty points may be penalized in the same way, but each user may be penalized in different ways. For example, when a plurality of users select the second mode before starting the screen golf play, each of the plurality of users who select the second mode sets their own desired disadvantage method, and a penalty is given to a certain user. For other users, you can make your mulligan opportunity deprived.

On the other hand, it is not necessary to deal with penalty points so that penalties are incurred. In other words, as shown in (1)-(4), the screen golf system does not determine how to deal with the penalty points after completing the screen golf, rather than making a decision in the screen golf system to cause a specific penalty based on the penalty points. . If users who play screen golf together allow others to hit abnormally, they will be able to tolerate that no additional penalties will occur even though penalty points have been imposed. Or, even if the screen golf system does not incur a separate penalty for penalty points, the users who played screen golf together make an agreement to pay the screen golf cost to the person with the highest penalty points. You can make it happen.

As described above, a penalty point may be imposed on a user who makes an abnormal hit according to the second method under the second mode. In the case of imposing penalty points, since the penalty points have already been penalized, the flying distance can be calculated in the same manner as in the first mode. For this, as described below, it is possible to induce a certain disadvantage by changing the method of calculating the trajectory of the golf ball without imposing a penalty point (of course, while imposing a penalty point, at the same time, the flying distance as described below) It can also be calculated to increase the disadvantage.)

Specifically, after calculating the flying distance of the golf ball according to the second method under the second mode, it may be artificially reduced. Referring to FIG. 10, first, a trajectory of a golf ball is calculated in the same manner as in the first method. That is, when the golf ball (B) hit by the user has a predetermined speed (V1) and direction (θ1), the control unit allows the golf ball (B) to move with the above physical parameters (V1, θ1). What kind of trajectory (T1) it has at the time is calculated. After calculating the trajectory T1 in this way, the flying distance of the golf ball B is artificially reduced by a predetermined distance d. Here, the reduction amount of the flying distance may be set to be proportional to the inclination of the point where the virtual golf ball is located on the screen. In general, it can be seen that as the inclination increases, the difficulty of hitting increases, and as the difficulty of hitting increases, it can be seen that the flying distance decreases. Therefore, the amount of reduction in the flying distance can be set to increase according to the inclination. The reduction in the flying distance may be set to decrease a predetermined value, such as 5m, 10m, 15m, depending on the inclination, or a specific percentage of the flying distance corresponding to 5%, 10%, and 15% of the calculated flying distance according to the inclination is reduced. Can be set.

In this way, the parameter representing the physical properties of the golf ball B is extracted, the trajectory T1 is calculated using the parameter as it is, and then the flying distance is artificially reduced.

Alternatively, instead of reducing the flying distance, a method of changing a parameter representing the physical properties of the golf ball B may be applied in another manner. Referring to FIG. 11, when it is assumed that the golf ball B hit by the user has a predetermined speed V1 and a direction θ1, a first trajectory T1 is obtained from the physical parameters V1 and θ1. If calculated, in this method, a trajectory is calculated after some of the physical parameters are modified by reflecting the inclination of the point where the virtual golf ball is placed on the screen 52. For example, in the physical state of the detected golf ball, if the vertical angle between the horizontal plane and the moving golf ball is'θ1' and the inclination of the point where the virtual golf ball is placed is'α', then'θ1, α' By using the direction value of the physical parameters of the golf ball, the deformation value'θ2' is calculated as follows.

θ2 = f(θ1, α)

When the deformation value'θ2' is calculated from the initial direction value θ1 as above, the trajectory T2 is calculated from the velocity V1 and the deformation value θ2. Here,'f(θ1, α)' can be called a function or formula using θ1, α as variables, and in the simplest form

f(θ1, α) = θ1 + α

Can be.

Or, by putting a predetermined weight (β) on the degree to which the gradient is reflected,

f(θ1, α) = θ1 + α×β

Can be.

Or, through various experiments, it is a little more complicated, but you can create and apply an equation that matches the actual situation.

In this way, after extracting a parameter representing the physical properties of the golf ball B, artificially transforming some of the parameters, and calculating the trajectory T2 based on this, the second method is processing.

As above, in the second mode, in order to penalize the hit (abnormal hit) when the screen condition and the plate condition are inconsistent, the trajectory of the golf ball is the hit when the screen condition and the plate condition are matched (normal hitting). A method of adjusting the flying distance in a different manner from the case of normal hitting may be applied instead of giving a penalty point while calculating the same as in the case of ), or not giving a penalty point. However, the methods presented here are only a few examples, and there may be various methods that can be applied to the second mode.

In addition, until now, various methods of processing in the second mode for giving disadvantages to abnormal hits compared to normal hits have been described, but the second mode does not necessarily need to be processed so as to be disadvantageous to the user. The purpose of playing screen golf may be different for each user, and a user who enjoys screen golf only for entertainment purposes to relieve stress may play with abnormal blows under the second mode, but may not want to incur a separate disadvantage due to this. Because. Therefore, only normal hits are effective under the first mode, and only abnormal hits are valid under the second mode, but under the first and second modes, both the flying distances of the golf ball are calculated in the same manner, and there is a special disadvantage for the player in the second mode. It may be configured not to be applied.
