Description

Putting guide formation method and virtual golf device using the same

The present invention relates to a method for forming a putting guide capable of providing information on putting to a user in a putting situation and a virtual golf device using the same.

Recently, the number of people who enjoy playing golf is increasing. As for golf, not only actual golf played on an outdoor golf course, but also screen golf that can be played using a virtual golf device and the like are popular. In screen golf, since an image of a golf course is displayed through a screen, it gives the impression that an actual golf game is being played outdoors, but has the advantage of saving time and money compared to playing on an outdoor golf course.

In golf, since the course strategy is completed only when the golf ball is put into the hole cup, 'putting', which rolls the golf ball toward the hole cup in the green area, is more important than any other hitting motion in golf. In actual golf, the user measures the distance between the golf ball and the hole cup and performs putting in consideration of topographical characteristics of an area between the golf ball and the hole cup. Here, one of the main topographical characteristics of the area between the golf ball and the hole cup is that the height changes in the area, resulting in a slope. Screen golf is configured to reflect the topographical characteristics of the area between the golf ball and the hole cup in actual golf, but it is not easy for the user to recognize the topographical characteristics such as the inclination of the green area just by looking at the two-dimensional flat screen. Therefore, in screen golf, it is necessary to inform the user of information useful for putting.

The present invention has been invented in view of the above circumstances, and an object of the present invention is to provide a method of forming a putting guide to provide a putting guide indicating information on putting in a putting situation.

The putting guide forming method may further include displaying a trajectory of the virtual golf ball moved by the user's putting and the expected trajectory together after the user completes putting.

In the putting guide forming method, the expected trajectory may be obtained by performing at least one simulated putting on the virtual golf ball. Here, the simulated putting is performed a plurality of times in each direction in a plurality of directions, and as a result of the simulated putting, the direction when the number of times the virtual golf ball is holed into the hole cup is the maximum is determined as the putting direction in the putting guide. direction can be Alternatively, the simulated putting is performed n times in the n-th direction (where n is a natural number of 1 or more), and when the virtual golf ball is holed in the hole cup as a result of the n-time mock putting, the n-th direction is referred to as the n-th direction. direction of the putting guide, and when the virtual golf ball does not hole in the hole cup as a result of the nth round of mock putting, the nth direction is changed to the n+1th direction and n+1th round of mock putting is performed. can

In the method of forming the putting guide, the putting guide may further include additional information representing topographical characteristics of an area adjacent to the hole cup.

1 is a diagram showing a schematic structure of a virtual golf device according to an embodiment of the present invention.

Referring to FIG. 1 , a virtual golf device according to an embodiment of the present invention includes a hitting plate 10, a control unit 20, a sensing unit 30, an input unit 40, a sound unit 50, and a display unit 60. include

The hitting plate 10 is an area where a user is positioned to hit a golf ball. The hitting plate 10 includes a hitting mat, and the user puts the golf ball on the hitting mat and hits the hitting plate. Although not shown in the drawing, an auto tee having a structure that can move up and down is installed on the hitting mat, so that a golf ball for hitting can be automatically provided to the user through the auto tee.

The controller 20 controls the overall operation of each component of the virtual golf device. For example, the controller 20 may control the auto tee installed on the hitting mat so that a golf ball for hitting is provided from the auto tee according to the timing of the user's hitting. Also, when the user selects a specific golf course, the controller 20 performs necessary operations so that the user can play on the golf course. That is, the controller 20 may transmit an image of a specific golf course selected by the user to the display unit 60 through the image processing means to display the image. In addition, when a user inputs personal information such as an ID or password for log-in, the control unit 20 may play a role of determining whether to approve the log-in by checking the input personal information. In addition, the controller 20 calculates a trajectory assuming that the golf ball flies in an actual golf course in the sensed state based on the physical state of the golf ball hit by the user.

The sensing unit 30 detects the motion of the golf club or the motion of the golf ball hit by the user to grasp physical state information about the hit golf ball, etc., and is a camera capable of capturing the motion of the golf club or golf ball. A sensing means such as a sensor or the like may be used. Various sensing methods such as image sensing, light emitting/light receiving sensing, and laser sensing may be applied to the sensing means, and the motion of a golf club or state information of a golf ball hit by a user may be grasped by such a sensing method. The camera or detection sensor may be used alone or together, and only one may be used, or several may be used as needed.

The input unit 40 is for receiving various types of information from a user, and a keyboard or mouse may be used. A login system that requires a user to log in before providing service may be applied to screen golf, and if the login system is applied, the input unit 40 may be used when a user inputs his/her ID or password. In addition, the input unit 40 can be used even when a user selects a golf course to play or a level of difficulty in screen golf.

The sound unit 50 may include a sound device such as a speaker, and through this, guides the user to the progress of the game and plays a role of playing various sound effects according to the progress of the game.

The display unit 60 includes devices such as a beam projector and a screen. The beam projector projects a related image onto the screen so that the golf course and the golf ball are displayed on the screen, and the screen serves to display the projected image to the user. In this specification, there is a case where the term 'virtual' is attached to some objects displayed on the screen, which is used to mean that they are displayed as images on the screen, and to avoid confusion with objects existing in the real world. it will be used For example, 'virtual golf ball' means a golf ball displayed on a screen, and it is expressed by attaching the term 'virtual' so as not to be confused with a real golf ball hit by a user in the real world.

The virtual golf device is a device installed in a screen golf course to play screen golf, and when a user plays screen golf, the virtual golf device operates in the following process. When the user strikes the golf ball, the sensing unit 30 detects physical conditions such as the movement of the golf club or the speed or direction of movement of the golf ball hit by the user. The information detected by the sensor 30 is transmitted to the controller 20, and the controller 20 determines the trajectory of the golf ball based on the transmitted information assuming that the user hits the golf ball at an outdoor golf course. Calculate what to show The trajectory of the golf ball may be calculated only by the movement of the golf ball or may be calculated by considering the movement of the golf club at the time of hitting. The display unit 60 displays an image of the virtual golf ball moving according to the calculated trajectory. At this time, the virtual golf ball flies along the calculated trajectory and lands at a specific point of the virtual golf course on the screen, and the user can The next hit continues at the point where the virtual golf ball landed.

When the virtual golf ball lands on the green area of the virtual golf course through the above hitting process, the user performs 'putting' by rolling the golf ball so that the virtual golf ball is holed in the hole cup located in the green area. In the putting step, the controller 20 generates a putting guide to provide information on putting, and the putting guide may be provided to the user through a screen. Hereinafter, a specific method of forming a putting guide will be described with reference to the drawings.

2 is a flow chart showing a method of forming a putting guide according to an embodiment of the present invention, and FIGS. 3 to 6 are diagrams showing individual processes of the method of forming a putting guide.

Referring to Figure 2, the process of the putting guide forming method includes first to third steps (S1, S2, S3). In the first step (S1), a virtual golf ball before putting on the green area and a hole cup, which is the target point of putting, are displayed, and in the second step (S2), mock putting is performed on the virtual golf ball at least once. By doing so, a putting guide that informs putting information is generated, and in the third step (S3), the generated putting guide is displayed and provided to the user.

Referring to FIG. 3(a), in the first step S1, a virtual golf ball located in the green area and a hole cup as a target point are displayed. The virtual golf ball is in a state of resting on the green area at the stage immediately before putting. The user may check the distance between the virtual golf ball and the hole cup by looking at the virtual golf ball and the hole cup displayed on the screen. In order to successfully putt, it is necessary to determine the distance between the virtual golf ball and the hole cup and also to determine the topography between the virtual golf ball and the hole cup to roll the golf ball in an appropriate direction and strength. In actual golf, the terrain of the green area is more often a complex sloped terrain with irregular heights than a simple flat land. Since most of the virtual golf courses displayed on the screen of the virtual golf device are modeled after the golf course of the actual golf course, the green area of the virtual golf course is often a sloped terrain, but the virtual golf course on the screen is a two-dimensional plane. Since it is displayed on the screen, it is not easy for the user to grasp the slope of the drawn area only with the image on the screen. For example, in FIG. 3 (a), there is shown a situation in which a hole cup is positioned in front of a virtual golf ball. In this situation, even if a real golf ball corresponding to the virtual golf ball is putt frontally, the green area is inclined. If there is, the probability of succeeding in putting is not high. For example, if the topography of the green area in the screen is not flat but slopes with a high left side and a low right side, there is a high possibility that the virtual golf ball will roll to the right with respect to the hole cup even when putting forward. Therefore, in the putting step, it is necessary to putt in consideration of the topographical characteristics of the green area in the virtual golf course, and for this purpose, the topographical characteristics of the green area may be displayed. Specifically, as shown in FIG. 3(b), a grid G composed of a plurality of horizontal lines G1 and vertical lines G2 is displayed in the green area, and the horizontal lines G1 and vertical lines In (G2), a plurality of horizontal indicators I1 and a plurality of vertical indicators I2 are displayed to move, respectively, so that the topographical characteristics of the green area can be indicated. The horizontal indicator I1 moves at a predetermined speed on the horizontal line G1, and the longitudinal indicator I2 moves at a predetermined speed on the vertical line G2. The horizontal indicator (I1) and the longitudinal indicator (I2) move from a high slope to a low slope of the green area where the corresponding indicator (I) is located, and their moving speed increases as the slope increases. Accordingly, when the grid G and indicator I are displayed, the user can grasp the direction and degree of slope in the green area through the moving direction and moving speed of the indicator I. The grid G and the indicator I do not necessarily have to be displayed, and if the user does not want them to be displayed, as shown in FIG. 3(a), they may not be displayed.

Referring to FIG. 4 , in the second step (S2), a putting guide is created by performing simulated putting at least once on a virtual golf ball. The simulated putting is performed internally in the control unit 20, and the specific process is not displayed externally. The simulated putting is performed by assuming that the user puts a golf ball in a specific direction from the position where the virtual golf ball is placed before putting, and the control unit 20 calculates the result of the putting through simulation. . This process is performed a plurality of times in the specific direction, and the simulated putting is repeated while changing the putting direction. For example, a position of a virtual golf ball before putting is referred to as a starting position, a position of a hole cup is referred to as a target position, and a direction from the starting position to the target position is referred to as a first direction. In addition, a direction biased to the left with respect to the first direction is referred to as a second direction, a direction biased to the right with respect to the first direction is referred to as a third direction, and a direction more biased to the left with respect to the second direction is referred to as a fourth direction, Assume that a direction more to the right with respect to the third direction is a fifth direction. It is also assumed that the simulated putting is performed 10 times in each of the first to fifth directions. In this way, simulated putting is performed to check the number of successful hole-ins for each putting direction. For example, 1 success in the 1st putting direction, 8 successes in the 2nd putting direction, 0 success in the 3rd direction, 3 successes in the 4th putting direction, and 0 success in the 5th direction. (Assuming that the green area slopes from left to right because the left side is high and the right side is low based on the first direction, when putting in the 3rd and 5th directions corresponding to the right of the first direction, the golf ball tilts the green area It is difficult to succeed in putting because it curves to the right along the right side), and since the second putting direction has the highest possibility of putting success, this is selected as the putting direction.

Not only the direction of putting, but also the strength of putting (strength indicating how hard the golf ball is rolled when putting) may affect the putting result. Therefore, mock putting can be performed to determine the proper strength of putting. The simulated putting assumes that the user puts a golf ball with various strengths in a specific direction at a position where a virtual golf ball is placed before putting, and the control unit 20 calculates the result of the putting through simulation. understand by doing If the position of the imaginary golf ball before putting is called the starting position, the position of the hole cup is called the target position, and the putting direction is a predetermined direction skewed to the left with respect to the direction from the starting position to the target position, a specific intensity for that direction is obtained. Practice mock putting. Mock putting is performed multiple times for the specific strength, and mock putting is repeated while changing the putting strength. For example, mock putting is performed 10 times for each of the different first to third strengths, and the number of successful hole-ins for each mock putting is checked. For example, if there is one successful putting for the first putting strength, eight successes for the second putting strength, and zero successes for the third putting strength, it can be said that the second putting strength has the highest possibility of putting success. Therefore, it is selected as putting strength.

Referring to FIG. 6 , in the third step (S3), a putting guide PG including information such as a putting direction or putting intensity identified through the above process is provided to the user. The putting guide may be expressed in the form of an arrow departing from a virtual golf ball, where the putting direction may be indicated through the direction indicated by the arrow. In addition, in the putting guide, the thickness or length of the arrow may be displayed differently, and the putting strength may be indicated according to the thickness or length. Alternatively, the thickness or length of the arrow may be constant and the color of the arrow may be expressed differently to indicate the putting intensity. Here, although the putting guide PG has been expressed in the form of an arrow, the putting guide PG does not have to be expressed only in the form of an arrow, and may be expressed in various shapes or shapes.

As described above, by providing the putting guide indicating putting information, the user can accurately grasp the topographical characteristics of the green area and accurately putt based on the putting guide.

When forming a putting guide, other methods may be used in addition to the above method of finding the optimal putting direction and putting strength by randomly simulate putting in a plurality of directions and strengths. The method described below has the advantage of reducing the number of simulated putts as a method of tracking the optimal putting direction and putting strength while performing nth mock putting.

7 to 11 are views for explaining a putting guide forming method according to another embodiment of the present invention.

According to this embodiment, as a result of the mock putting, the mock putting is repeatedly performed until the putting is successful (the virtual golf ball is holed in the hole cup). For example, if the putting direction in the nth mock putting is the n-direction (n is a natural number greater than 1), if the n-th direction is successful in the nth mock putting, the mock putting is stopped and the nth direction is given to the user. A putting guide for guiding in the putting direction is provided. If the nth direction of mock putting fails in the nth mock putting, the n+1th mock putting is performed after correcting the direction to the n+1th direction different from the nth direction.

The putting direction (nth direction) in the nth mock putting is selected in the following way. Referring to FIG. 7, when the position of the virtual golf ball before putting is referred to as the starting position, the position of the hole cup is referred to as the target position, and the direction from the starting position to the target position is referred to as the reference direction, the first simulated putting is performed in the first direction. This is set as the reference direction and implemented. If the topography of the green area is flat and has no slope, the virtual golf ball is putt in the direction of the hole cup in the first round of mock putting, so there is a high possibility of hole-in in the hole cup. Provides a putting guide that guides you to and ends mock putting.

If the topography of the green area is in a state where the left side is high and the right side is low, so that it is inclined from left to right, as shown in FIG. If the left side of the green area is referred to as the left area and the right side of the green area is referred to as the right area based on the first direction, the virtual golf ball arrives at the right area without being holed in the first round of mock putting and stops. In this way, when the virtual golf ball reaches the right area without hole-in as a result of the first round of mock putting, the putting direction in the second and subsequent rounds of mock putting is set to face the left area. In the mock putting after the second round, the putting direction is directed to the left area, but the mock putting is performed until the virtual golf ball is holed while changing the angle between the reference direction and the putting direction. For example, as shown in FIG. 8(a), as a result of simulated putting in the n-th direction in the n-th mock putting after the second round, when the virtual golf ball reaches the left area without hole-in, n+ The first direction is adjusted to the side closer to the reference direction than the nth direction (the angle between the reference direction and the n+1th direction is smaller than the angle between the reference direction and the nth direction), and the n+1th round of mock putting is conducted. do. In addition, as shown in FIG. 8(b), as a result of simulated putting in the n-th direction in the n-th mock putting after the second round, when the virtual golf ball reaches the right area without hole-in, the n+1-th direction is The n+1th mock putting is performed by adjusting to a side farther from the reference direction than the nth direction (the angle between the reference direction and the n+1th direction is larger than the angle between the reference direction and the nth direction). In this way, if the putting direction of the mock putting in the next round is set by reflecting the result of the mock putting in the previous round, the more the mock putting proceeds, the more it converges to the proper direction and the hole-in succeeds. A putting guide is provided to guide the direction to the putting direction, and the simulated putting is finished.

If the topography of the green area is in a state where the left side is low and the right side is high, so that it slopes from right to left, the virtual golf ball in the first simulated putt is bent to the left from the hole cup and fails to hole-in. That is, in the first simulated putt, the virtual golf ball does not hole in and stops after reaching the left area (a situation opposite to that shown in FIG. 7). In this way, when the virtual golf ball reaches the left area without hole-in as a result of the first round of mock putting, the putting direction for the second and subsequent rounds of mock putting is set to face the right area. In the mock putting after the second round, the putting direction is directed to the right area, but the mock putting is performed until the virtual golf ball is holed while changing the angle between the reference direction and the putting direction. As a result, if hole-in is successful in the nth mock putting, a putting guide for guiding the nth direction to the putting direction is provided, and the mock putting is finished.

Since the results of putting can vary depending on the strength as well as the direction, a simulated putting can be performed to determine the proper strength of putting. For example, if the putting intensity in the nth mock putting is nth intensity (n is a natural number of 1 or more), the mock putting is stopped if the putting is successful in the nth mock putting (the virtual golf ball is holed in the hole cup), A putting guide for guiding the n-th strength to the putting strength is provided to the user. If the nth simulated putting fails, the n+1th simulated putting is performed after changing the putting intensity to the n+1th intensity different from the nth intensity.

The putting strength (nth strength) in the nth round of simulated putting is selected as follows. Referring to FIG. 9, if the position of a virtual golf ball before putting is the starting position, the position of the hole cup is the target position, and the direction from the starting position to the target position is the reference direction, the first simulated putting is in the reference direction. The putting strength at this time is set so that the target is a position farther away from the starting position than the target position. That is, if the distance from the start position to the target position is 'L', the first strength is set such that the distance from the start position to the target position (target position) is 'L+ΔL'. The ΔL is set to approximately 0.5m to 1.5m, preferably 1m. Alternatively, ΔL may be set to be about L/10 to L/5 with respect to the distance (L) from the start position to the target position. For example, if the distance from the start position to the target position is 5 m, the distance from the start position to the target position may be set to 6 m. This means putting with an intensity that can pass the target position 5m ahead by about 1m. The reason why the putting strength is set to a level that can slightly exceed the target position is that if the putting strength is too weak, the putt golf ball may not reach the hole cup due to lack of rolling power, and if the putting strength is too strong, the putt will go in the right direction. This is because the putt golf ball can pass through the hole cup even if it does.

The putting intensity in the simulated putting after the second round may also be set as a target at a position slightly further away from the target point. For example, as shown in FIG. 10, assuming that n times of mock putting is performed in the n-th direction, a point where a virtual straight line moving along the n-th direction meets a virtual horizontal line passing through the hole cup (the location of the target point) If the position of is called the n-th position, the putting intensity (n-th intensity) of the simulated putting can be set to a level of intensity that targets a position approximately 0.5m to 1.5m further away from the nth position in the n-th direction. there is. Alternatively, the putting strength of the mock putting after the second round may be set by reflecting the putting result of the previous round of mock putting. Referring to FIG. 11, when the virtual golf ball is not holed as a result of the nth mock putting, the putting strength of the nth mock putting is referred to as nth strength, and the position at which the virtual golf ball arrives as a result of the simulated putting is nth. Assume the location As shown in FIG. 11 (a), the vertical distance (l) from the starting position where the virtual golf ball is located before putting to the n-th position is the target where the virtual golf ball is located before putting and the hole cup is located. If it is smaller than the distance (L) between the positions of the points, it is determined that the putting strength is insufficient, and the n+1th strength is set to be greater than the nth strength, and simulated putting is performed for the n+1th round. In addition, as shown in FIG. 11 (b), on the contrary, the vertical distance (l) from the starting position at which the virtual golf ball is located before putting to the n-th position is the starting position at which the virtual golf ball is located before putting and the position of the hole cup. If it is greater than the distance (L) between the positions of the target points to be played, it is determined that the putting strength is too strong, and the n+1th strength is set to be smaller than the nth strength, and simulated putting is performed for the n+1th round. In this way, if the putting strength of the mock putting in the next round is set by reflecting the result of the mock putting in the previous round, the more the mock putting proceeds, the more it converges to the proper strength and the hole-in is successful. A putting guide that guides strength to putting strength is provided, and mock putting is stopped.

According to the present invention, the putting guide formed by the above method can be provided to the user in various ways as follows. 12 to 17 show various examples displayed on the screen to provide a putting guide to the user.

Referring to FIG. 12 , the putting guide PG may be displayed to indicate an expected trajectory of a virtual golf ball moving by putting. Previously, it was explained that a putting guide can be formed through mock putting. In the case of mock putting, the virtual golf ball position before putting to the hole in the hole cup in case of successful putting through mock putting is explained. Since the trajectory of the golf ball can be grasped, the trajectory can be displayed on the screen as an expected trajectory. When there is an inclination in the green area, the expected trajectory indicates the location and degree of bending of the virtual golf ball due to the inclination. Therefore, if the putting guide PG is displayed with the expected trajectory of the virtual golf ball moving, the user can enter the green area It has the advantage of being able to intuitively and clearly grasp the slope and direction of the slope and use it for putting.

Referring to Figure 13, the putting guide (PG) may be displayed in plurality. The two main pieces of information indicated in the putting guide (PG) are the putting direction and the putting strength. The putting direction may vary depending on the direction in which the green area is inclined, and the putting strength may vary depending on how steep the green area is. In addition, even when putting at the same location on the green area, the putting direction and putting intensity may be different. When using the slope of the green area as much as possible, the putting direction and strength can be reduced, and when the slope of the green area is used as little as possible, the putting direction and strength can be increased. For example, as shown in FIG. 13, the putting guide PG may be represented by an arrow, the direction of the arrow indicating the putting direction, and the length of the arrow indicating the putting strength. Here, the putting guide (PG) may be composed of a first putting guide (PG1) and a second putting guide (PG2) having different putting directions and putting strengths as a plurality. If it is assumed that the topography of the green area is high on the left and low on the right, so that it slopes from left to right, the putting direction may be set to be biased to the left with respect to the direction from the virtual golf ball to the hole cup. The first putting guide PG1 is more biased to the left than the second putting guide PG2, and the first putting guide PG1 is set to a stronger strength than the second putting guide PG2. When the virtual golf ball starts along the putting direction from the initial position by putting, it usually moves in the direction of going against the slope of the green area. After the virtual golf ball has rolled to some extent, it is affected by the slope of the green area, The direction in which the ball rolls is changed from the initial putting direction to a substantially opposite direction, and after the direction is changed, the virtual golf ball moves along the slope of the green area. As above, since the putting direction corresponds to the direction in which the virtual golf ball starts from the initial position against the slope of the green area, if the putting direction is more to the left than the reference direction, it moves against the slope of the green area by that much. Therefore, the virtual golf ball needs to move at a higher speed. Therefore, in the embodiment shown in Figure 13, the first putting guide (PG1) is biased more leftward than the second putting guide (PG2), and accordingly, the first putting guide (PG1) is the second putting guide ( Compared to PG2), it has stronger putting strength. In this way, according to the present embodiment, the putting guide PG may be displayed in a plurality of different putting directions and putting strengths, and the user selects the putting guide PG he or she wants from among the plurality of putting guides PG. Putting can be performed using this.

Referring to FIG. 14 , a plurality of putting guides PG are displayed, and each of the plurality of putting guides PG may be expressed as an expected trajectory of a golf ball. For example, the putting guide PG may include a first putting guide PG1 indicating a first expected trajectory and a second putting guide PG2 indicating a second expected trajectory. The first putting guide PG1 shows the direction that is most leftwardly biased in the direction from the virtual golf ball to the hole cup, and the second putting guide PG2 shows the smallest direction in the direction from the virtual golf ball to the hole cup. If it indicates a direction that is biased to the left, the putting direction between the putting direction of the first putting guide (PG1) and the putting direction of the second putting guide (PG2) can be seen as an intermediate putting direction that can be successful in putting. Therefore, when the putting guide PG is expressed as a plurality of expected trajectories, a predetermined area PGA surrounded by the expected trajectory of the first putting guide PG1 and the expected trajectory of the second putting guide PG2 is displayed The user may select an appropriate direction within this area (PGA) to putt.

Referring to FIG. 15, the putting guide PG is displayed on the screen only before putting because it is necessary information before the user puts, but in this embodiment, after the user completes the putt, the virtual golf ball The moving trajectory T (actual putting trajectory) and the expected trajectory indicated by the putting guide PG may be displayed on the screen together. When a user fails to putt, it is necessary to check what is wrong and failed. Since the expected trajectory indicated by the putting guide (PG) can be seen as representing an ideal model for a desirable putting, the putting guide (PG) and the actual putting When the trajectory (T) as a result of is displayed on the screen together, the user identifies problems in his/her putting (wrong putting direction, too strong or weak putting strength, etc.) You can improve your putting ability by supplementing it.

Referring to FIG. 16, the putting guide PG on the screen is displayed as an arrow indicating the putting direction or strength, and may include additional information PI in addition to this. For example, topographical information such as a gradient of an adjacent area adjacent to a hole cup may be separately displayed as additional information PI. An inclination in an area adjacent to the hole cup may be an important factor in determining whether or not the golf ball is holed into the hole cup. The gradient of the region near the hole cup can be expressed in various ways. As an example, as shown in FIG. 16, the direction of the arrow indicates the direction of inclination and the number of arrows indicates the degree of inclination.

If there is a downward slope in the direction of the hole cup in the left region A1 near the hole cup, the virtual golf ball may be easily holed in along the slope when passing through the corresponding region A1. In contrast, if there is a downhill slope (uphill slope in the direction of the hole cup) in the opposite direction of the hole cup in the lower area A2 near the hole cup, the virtual golf ball is likely to be pushed by the slope and not easily holed in when passing through the corresponding area A2 there is In addition, if there is a downhill slope (uphill slope in the direction of the hole cup) in the opposite direction of the hole cup in the right area A3 near the hole cup, the virtual golf ball is pushed by the slope when passing through the corresponding area A3. There is a possibility. As such, the slope of the area adjacent to the hole cup can act as an important variable that can easily guide a virtual golf ball that has rolled up to the hole cup to the hole cup or get it out of the hole cup, so it is an important factor that can determine the success of putting. It is a factor and can be a major concern for users who perform putting. Reflecting this point, in the present embodiment, information representing the topographical characteristics of the region near the hole cup is provided as additional information P1 of the putting guide PG.

Referring to FIG. 17, a plurality of putting guides PG are displayed, and each of the plurality of putting guides PG may be expressed as an expected trajectory of a golf ball. For example, the putting guide PG may include a first putting guide PG1 indicating a first expected trajectory and a second putting guide PG2 indicating a second expected trajectory. As shown in FIG. 17, when the first putting guide PG1 passes through the first area A1 near the hole cup and the second putting guide PG2 passes through the second area A2 near the hole cup , In this embodiment, one of the first and second putting guides PG1 and PG2 is recommended in consideration of the advantages and disadvantages of putting according to the topographical characteristics of the first and second areas A1 and A2, and the others are not recommended or not recommended. can For example, if the first area A1 is gently inclined in the direction of the hole cup and the second area A2 is steeply inclined in the opposite direction to the hole cup, the first area A1 is advantageous for putting to normal users. , The first and second putting guides PG1 and PG2 are displayed together, but a message recommending the first putting guide PG1 (or a message not recommending the second putting guide PG2) can be displayed on the screen. (Alternatively, a recommendation/non-recommendation message may be transmitted by voice through the sound unit 50). From the user's point of view, it is possible to putt using the recommended first putting guide P1, or to putt using the second putting guide P2 on purpose in a position to challenge a difficult level of difficulty.

18 is a diagram showing a schematic structure of a virtual golf device according to another embodiment of the present invention.

Referring to FIG. 18 , the virtual golf apparatus according to the present embodiment includes a plurality of booths 101, 102, and 103. Each booth 101, 102, 103 is configured identically. For example, the first booth 101 has a hitting plate 101a, a simulator device 101b equipped with a kiosk screen, a screen 101c, and the like, and the other booths 102 and 103 also have the same components. Although not shown in the drawing, each booth 101, 102, 103 is further equipped with other devices including a camera for detecting the movement of a golf ball. In each of the booths 101, 102, and 103, a plurality of users can alternately play golf. Alternatively, in each of the booths 101, 102, and 103, the user alone can enjoy a solo play while being separated from users of other booths. The simulator device 101b of the virtual golf device according to the present embodiment may include a control unit identical to or similar to that described above, and a putting guide that informs the user of putting information through the control unit may be provided.

19 is a diagram showing a schematic structure of a system in which a plurality of virtual golf devices are connected through a network, and FIG. 20 shows an example of displaying additional information on topographical characteristics of a green area on a screen.

Referring to FIG. 19, a system in which virtual golf devices are connected through a network includes a plurality of screen golf courses 1 and a server unit 2. The screen golf course 1 is provided with virtual golf devices as shown in FIGS. 1 to 18 and the like so that screen golf play can be enjoyed. The virtual golf device provided in the screen golf course 1 is connected to the server unit 2 through a wired or wireless communication network. Each screen golf course 1 serves as a service providing unit providing a screen golf service to the user when login is made. The server unit 2 may be a central server used by a service provider operating a plurality of screen golf courses 1 to manage virtual golf devices provided in the plurality of screen golf courses 1 . A user who wants to use the screen golf service logs in first to receive the service, and the server unit 2 can confirm the user's identity when logging in and determine whether to approve the log-in. To this end, the server unit 2 is provided with a storage unit 3 that stores information necessary for verifying the user's identity. In the storage unit 3, information on a plurality of users is stored separately for each user. In the storage area for each user, personal information, play information, setting information, and the like may be stored. The personal information is for confirming the identity of the corresponding user and can be used in a log-in process or the like. The play information may include a past play record of the corresponding user or a user's personal record (average distance per club, average number of strokes, etc.) obtained from the past play record. The setting information includes information on items set by the user, and the like. For example, a golf course the user has played in the past, play difficulty, play method, and preferred operating conditions may be stored as setting information. Users may find it cumbersome to input various options every time they play, but if the user does not input the options, the options may be automatically set based on the setting information. In this way, by storing various user information in the storage unit 3, the virtual golf devices of the screen golf course 1 connected to the server unit 2 are connected to the server unit 2 by wire and/or wirelessly. In this state, the information stored in the storage unit 3 can be commonly used together, and there is no need to separately store user information in each screen golf course 1. The virtual golf device of each screen golf course 1 is provided with the same or similar control unit as described above, and a putting guide that informs the user of information on putting can be provided through the control unit. For example, as shown in FIG. 20, the putting guide PG may be represented by an arrow indicating a putting direction and a putting strength. Also, as additional information, a plurality of areas A1 and A2 near the hole cups may be displayed. Among the plurality of areas, the first area A1 may represent an area with a high probability of success in putting, and the second area A2 may indicate an area with a low probability of success in putting. The probability of success of putting can be obtained by analyzing records played by players in the past on the corresponding golf course. That is, since the user's individual play information is stored in the storage unit 3, it is possible to obtain information by collecting records of users on a specific golf course. If the collected information is analyzed, the golf ball passes when the users successfully putt. An area containing many paths may be displayed as a first area A1, and an area containing many paths through which golf balls may pass when users fail in putting may be displayed as a second area A2. This is the result of statistically analyzing objective data such as past play records. From the user's point of view, it is possible to putt the first area (A1) with a high probability of success according to one's preference, or to deliberately challenge because the probability of success is low. You can putt the second area A2 as a target with your mind. Here, an embodiment in which two areas of the first and second areas A1 and A2 are displayed has been described, but a larger number of areas may be displayed. In addition, the first and second regions A1 and A2 may be expressed in different colors so as to be visually easily identified. For example, the first area A1 may be expressed in blue or green color, and the second area A2 may be expressed in red color.
