Description

The present invention relates to a virtual golf device that adjusts a flight distance. More specifically, the present invention relates to a virtual golf device capable of calculating a trajectory of a virtual golf ball on a virtual golf course based on a golf ball hit by a user and further adjusting a flight distance based on the trajectory.

Recently, a simulation device that allows you to enjoy sports competitions without going to the site has been developed and widely used using 3D stereoscopic images and computer simulation technology. Especially in the case of screen golf played indoors, it saves time and money compared to playing in the field outdoors while giving the feeling of playing an actual golf game outdoors. It is very popular with modern people who have difficulty playing outdoor golf due to time or financial reasons.

In actual golf, when a golf ball is hit, the next hit is made at the point where the golf ball flies and lands. However, the point where the golf ball lands on the golf course of the golf course can have various characteristics. For example, a golf course has areas with various attributes such as fairways, roughs, bunkers, and water hazards, and depending on the attributes of these areas, a hit when a user hits a golf ball landed in the area. Feeling and difficulty change. Further, even in an area having the same attribute, when the area has an inclination, the feeling of hitting and the difficulty level when the user hits the golf ball changes as compared with the case where there is no inclination. In this way, in actual golf, various types of hits must be made depending on the characteristics of the point where the golf ball lands, but in screen golf, the user hits the golf ball placed on the hitting mat. However, from the user's point of view, it is not possible to experience various methods of hitting like real golf. As a result, screen golf has a problem that it lacks reality compared to playing on an actual golf course.

The present invention has been invented in consideration of the above circumstances, and by appropriately adjusting the flight distance calculated after hitting based on the position where the golf ball is placed on the screen, the screen The purpose is to provide a virtual golf device with improved golf reality.

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

In the virtual golf device according to the embodiment of the present invention, the movement of the virtual golf ball on the virtual golf course is based on the display unit displaying the virtual golf course and the virtual golf ball and the state of the actual golf ball hit by the user. Includes a control unit that performs a calculation step to calculate. The control unit determines whether or not the adjustment step can be performed based on the point where the virtual golf ball is placed on the virtual golf course before the user hits the ball. In the adjustment step, the calculation step is calculated. The flight distance of the virtual golf ball is adjusted.

In the virtual golf device, the virtual golf course includes a virtual fairway area and a virtual non-fairway area, and whether or not the adjustment step can be performed and the flight distance adjusted when the adjustment step is performed are determined before the user hits. It depends on where the virtual golf ball is located in the virtual fairway area and the virtual non-fairway area.

The virtual golf device further includes a batting mat on which an actual golf ball hit by the user is placed, and a sensing unit that senses the state of the actual golf ball hit by the user and transmits the state to the control unit.

In the virtual golf device, the batting mat corresponds to a single region striking mat composed of only a fairway region corresponding to the virtual fairway region, or a fairway region corresponding to the virtual fairway region and the virtual non-fairway region. It is a striking mat in multiple areas including a non-fairway area.

In the virtual golf device, the hitting mat is a hitting mat having a plurality of regions, and the sensing unit senses a region where the actual golf ball is placed on the hitting mat, and the hitting mat actually hits the user. The adjustment step is performed when the golf ball and the virtual golf ball are located in regions that do not correspond to each other.

In the virtual golf device, whether or not the adjustment step can be performed and the flight distance adjusted when the adjustment step is performed are determined by the inclination of the point where the virtual golf ball is placed and the virtual golf ball before the user hits the ball. It depends on the height of the point where the virtual golf ball is placed and at least one of the distances from the point where the virtual golf ball is placed to the hole cup.

In the virtual golf device, whether or not the adjustment step can be performed and the flight distance adjusted when the adjustment step is performed depend on the level of the user.

In the virtual golf device, the level of the user is calculated based on at least one of the number of plays, the play time, and the play record of the user.

In the virtual golf device, the user can set whether or not the adjustment step can be performed and the flight distance to be adjusted when the adjustment step is performed.

In the virtual golf device, in the adjustment step, the smaller the inclination of the area where the virtual golf ball is placed before the user hits, and / or the virtual golf ball is placed before the user hits. The higher the height of the area and / or the farther the distance from the area where the virtual golf ball is placed to the hole cup before the user hits, the more the amount of decrease in the flight distance is reduced. Adjust by making it smaller or increasing the amount of increase in the flight distance.

According to the virtual golf device of the present invention, the reality of screen golf can be improved by appropriately adjusting the flight distance calculated after hitting based on the position where the golf ball is placed on the screen.

In addition, the shape of the illustrated element may be slightly changed due to mutations in the manufacturing process. Therefore, the examples disclosed herein should not be limited to the illustrated shapes and should be understood to include some modifications, unless otherwise noted.

FIG. 1 shows a schematic structure of a virtual golf device according to an embodiment of the present invention, and FIG. 2 is a block configuration diagram for a main configuration of the virtual golf device of FIG.

With reference to FIGS. 1 and 2, the virtual golf device includes a batting plate (P), a sensing unit (10), an input unit (20), a simulator (30), and a display unit (40). The striking plate (P) is provided with a striking mat (M) on which a striking golf ball is placed, and the golf ball is automatically placed on the striking mat (M) by another means such as an auto tee. Can be provided to.

The sensing unit (10) is for detecting the movement of the golf ball hit by the user and grasping the overall state information about the hit golf ball, and can capture the movement of the golf ball. Sensing means such as a capable camera or a sensing sensor capable of detecting the movement of a golf ball can be used. Various sensing methods such as image sensing, light emitting / receiving sensing, and laser sensing can be applied to the sensing means, and it is possible to grasp the state information of the golf ball hit by the user by such sensing methods. it can. The camera, the sensing sensor, and the like can be used alone or together. Moreover, only one may be used, or a plurality may be used.

The input unit (20) is for receiving various information from the user, and a keyboard, mouse, or the like can be used. In screen golf, it may be necessary for the user to enter information, such as when the user enters his or her ID or password, or when the user selects the golf course or difficulty level he or she wants to play. An input unit (20) is provided for such cases.

The input data from the input unit (20) is transmitted to the simulator (30) and processed. For example, when the user inputs a golf course that he / she wants to play, the simulator (30) operates so that the input virtual golf course is displayed to the user through the display unit (40). In this way, the simulator (30) processes various requests from users and the like while controlling the overall operation of the virtual golf device. As illustrated in FIG. 2, the simulator (30) includes a control unit (31), a video unit (32), and a database (33). The control unit (31) plays a role of calculating the movement of the golf ball hit by the user along with various control operations, and the video unit (32) plays a role of generating an image displayed to the user, and a database. (33) stores data necessary for the operation of the control unit (31) and the video unit (32).

The display unit (40) includes a beam projector (41) and a screen (42). The beam projector (41) projects the video data from the video unit (32) onto the screen (42), and the screen (42) displays the projected video and provides it to the user. The golf ball, golf course, etc. displayed on the screen (42) are not the actual golf ball, the golf course, etc., but the golf ball or golf course in the image. Name it with the term "no". In other words, the golf ball displayed in the image is a "virtual golf ball" so as not to be confused with the actual golf ball (Real Ball) that the user places on the striking plate (P) and hits. (Virtual Ball) ". Similar to the "virtual golf ball", a modifier "virtual" is added to an object to indicate that it is an object in the image. For example, the "virtual golf course" does not indicate the golf course of an actual golf course, but means that the golf course of the golf course is represented by an image on the screen. The actual golf ball to be hit should also be named "actual golf ball" with the modifier "actual" if necessary to prevent confusion with the virtual golf ball in the video. Can be done.

The virtual golf device according to the present embodiment is a device installed in a screen golf course and enables a user to play screen golf, and the general operation when the user plays screen golf is as follows. ..

FIG. 3 is a flowchart showing an operation method that can be applied to the virtual golf device of FIG. 1, FIG. 4 is a diagram for explaining a calculation step in FIG. 3, and FIG. 5 is a diagram for explaining an adjustment in FIG. It is a figure for demonstrating a step.

Referring to FIG. 3, the operation process of the virtual golf device according to the present embodiment includes a sensing step (S10), a calculation step (S20), an adjustment step (S40), a display step (S50), and the like.

In the sensing step (S10), the sensing unit (10) can detect the state and position of the actual golf ball placed on the hitting mat (M) before the user hits, and the user can play golf. When a ball is hit, the user senses a physical condition such as the speed or direction of movement of the hit golf ball.

In the calculation step (S20), the control unit (31) of the simulator (30) calculates the movement of the virtual golf ball on the virtual golf course. In the calculation step (S20), when data on the physical state of the hit golf ball is received from the sensing unit (10) and it is assumed that the user hits the golf ball at an actual outdoor golf course based on the data. Calculate what kind of trajectory the golf ball has.

Specifically, referring to FIG. 4, the actual golf ball hit by the user is checked and a parameter indicating the physical state of the ball (B1) after hitting is sensed. The parameters include the speed (V1) of the ball (B1), the spin (S1) indicating the rotation of the ball (B1), the azimuth angle (φ1) indicating the direction of the ball (B1) flying by hitting on the horizontal plane, and the ball. There can be upper and lower (θ1), etc., which indicate the angle at which (B1) is tilted with respect to the horizontal plane. Applying a calculation model that uses the laws of physics based on parameters such as velocity (V1), spin (S1), azimuth (φ1), and up and down (θ1), the trajectory (T1) of the ball (B1) is obtained. It can be calculated, and the trajectory (T1) of the virtual golf ball can be calculated from the physical state of the ball (B1) by such a method.

In the calculation step (S20), the parameters such as velocity (V1), spin (S1), azimuth (φ1), and vertical (θ1) are given by way of example, and are limited to those described here. Not done. Other parameters can be added to calculate the trajectory (T1) more precisely. Alternatively, the calculation step (S20) can be performed easily and quickly by omitting some parameters.

With reference to FIG. 3 again, the output step (S20) is followed by the step (S30) of checking whether the specific requirements are satisfied. If the specific requirements are met, the display step (S50) is performed after the adjustment step (S40) is performed. If the specific condition is not satisfied, the adjustment step (S40) is omitted and the display step (S50) is performed. There can be various specific conditions that determine whether or not the adjustment step (S40) can be performed, which will be described later.

In the adjustment step (S40), the flight distance adjustment process for reducing or increasing the flight distance of the golf ball calculated in the calculation step (S20) is performed. Specifically, referring to (a) of FIG. 5, parameters (velocity (V1), spin (S1), azimuth (velocity (V1), spin (S1), azimuth ( When the locus (T1) of the ball (B1) is calculated based on (φ1), vertical angle (θ1), etc.), if the landing position of the ball (B1) by the locus (T1) is the first position (LP1). In the adjustment step (S40), the flight distance of the locus (T1) in the calculation step (S20) is adjusted so as to decrease by a predetermined distance (Δ1). As a result, the landing position of the adjusted ball (B1) becomes the second position (LP2), and the trajectory (T2) of the ball (B1) is also changed. Alternatively, referring to (b) of FIG. 5, in the adjustment step (S40), the flight distance of the locus (T1) by the calculation step (S20) is adjusted so as to increase by a predetermined distance (Δ2). As a result, the landing position of the adjusted ball (B1) becomes the third position (LP3), and the trajectory (T3) of the ball (B1) is also changed.

When the adjustment step (S40) is omitted in the display step (S50), the display unit (40) displays an image of the virtual golf course and the virtual golf ball based on the calculation result in the calculation step (S20). When the golf course is displayed and the adjustment step (S40) is passed, the display unit (40) reflects the adjustment result in the adjustment step (S40) on the calculation result in the calculation step (S20), and the virtual golf course and the said virtual golf course The image of the virtual golf ball is displayed.

The following describes the specific requirements that determine whether or not the adjustment step (S40) can be performed. In addition, when the adjustment step (S40) is carried out, how much the flight distance is reduced or how much the flight distance is increased will be described (hereinafter, the reduction rate and increase of the flight distance in the present specification). The ratio is expressed by naming it as "adjustment rate"). The description below is part of the various requirements and criteria, and other requirements and criteria not discussed here may apply.

FIG. 6 shows a virtual golf course displayed on the screen of the virtual golf device of FIG. 1, and FIGS. 7 and 8 show a single area striking mat that can be used for the virtual golf device of FIG. It is a figure for demonstrating the case where the adjustment step is applied, and FIGS. 9 to 11 show a multi-region hitting mat that can be used for the virtual golf device of FIG. 1, and the adjustment step is applied here. It is a figure for demonstrating a case.

Referring to FIG. 6, a virtual golf course is displayed on the screen while playing screen golf. A virtual golf course is a computer graphics representation of a golf course that actually exists or is created without it. Whether it is a representation of an actual golf course or a representation of a created golf course, the virtual golf course displayed on the screen is a real golf course so that you can improve the reality of screen golf. It reflects the characteristics of the golf course to the maximum extent. For example, a golf course on an actual golf course has terrain with various attributes such as fairways, roughs, and bunkers, and a virtual golf course on the screen also has virtual fairways, roughs, and virtual bunkers. , The terrain with various attributes is displayed. A fairway in an actual golf course is an area where the turf is kept short, so that the golf ball can be easily hit. The rough is an area with longer grass than the fairway, and the rough with long grass is more difficult to hit than the fairway with short grass. Bunkers are areas of sand that are even more difficult to hit due to the sand and are more difficult to hit than areas of turf (fairways, rough).

With reference to FIG. 7, as the striking mat (M), one consisting of a single area can be used. In the single area striking mat (M), the single area is composed of a fairway area corresponding to a virtual fairway in the screen. That is, the fairway area of the single area striking mat (M) is composed of artificial turf or the like having a short length so that the fairway of an actual golf course has a short turf and is easy to hit. It is possible to provide the same feeling of hitting and difficulty of hitting on the fairway of the field.

When the user hits the golf ball, he actually hits the actual golf ball on the hitting mat (M), but in the setting in screen golf play, at the point where the virtual golf ball on the screen is placed. Suppose you hit a golf ball. For example, if a virtual golf ball on the screen is placed on a virtual fairway, it is assumed that the golf ball placed on the area of the fairway is hit, and the virtual golf ball on the screen is placed on the virtual rough. If so, assume that you are hitting a golf ball that is placed on the rough. When using a single area striking mat (M), as illustrated in (a) of FIG. 8, when the virtual golf ball (VB) in the screen is placed on the virtual fairway, the striking mat Hitting an actual golf ball (RB) placed in the fairway area of (M) corresponds to the situation on the screen. However, as illustrated in Figure 8 (b) and Figure 8 (c), if the virtual golf ball (VB) in the screen is placed in a virtual rough or virtual bunker, then a single area The striking mat (M) does not provide an environment in which it can be striked to correspond to this. In general, hitting with a rough or bunker is more difficult than hitting with a fairway, so when hitting with the same swing, the flight distance of the golf ball decreases in the order of fairway, rough, and bunker. With this in mind, adjustment steps can be applied when the virtual golf ball (VB) in the screen is hit in a virtual rough or virtual bunker. Specifically, assuming that the flight distance calculated when the virtual golf ball (VB) is hit while being placed on the virtual fairway ((a) in FIG. 8) is 100, the virtual golf ball (VB) is When hitting while placed on the virtual rough ((b) in Fig. 8), apply the adjustment step to reduce the final flight distance to 90 (adjustment rate is -10%), and then use the virtual golf ball ( When hitting while the VB) is in the virtual bunker ((c) in Figure 8), the adjustment step can be applied to reduce the final flight distance to 80 (adjustment rate is -20%). ).

In the adjustment step, not only the flight distance can be reduced, but also the flight distance can be increased. For example, the flight distance of a golf ball when hit with the same swing is calculated in the calculation step (S20) in the case shown in FIG. 8 in consideration of the fact that the flight distance decreases in the order of fairway, rough, and bunker. Assuming that the flight distance is 100, when the virtual golf ball (VB) is hit while being placed on the virtual fairway ((a) in Fig. 8), the final flight distance will be 120 in the adjustment step. (Adjustment rate is + 20%), and when hitting when the virtual golf ball (VB) is placed on the virtual rough ((b) in Fig. 8), the final flight distance is determined in the adjustment step. Set it to 110 (adjustment rate is + 10%) and apply the adjustment step when hitting when the virtual golf ball (VB) is placed in the virtual bunker ((c) in Fig. 8). Instead, the final flight distance can be maintained at 100 (adjustment rate is 0%).

With reference to FIG. 9, as the striking mat (M), one composed of a plurality of areas can be used. The striking mat (M) of a plurality of regions includes a first striking region (1) and a second striking region (2), and the second striking region (2) has two sub regions (2a, 2b). The first hitting area (1) corresponds to the fairway with the lowest hitting difficulty in actual golf, and the second hitting area (2) corresponds to the non-fairway having a higher hitting difficulty than the fairway (rough, bunker in this specification). Areas where the difficulty of hitting is higher than that of fairways are called "non-fairways"). The two sub-regions (2a, 2b) of the second striking region (2) can be formed to correspond to roughs and bunkers having different striking difficulty levels. For example, one sub-region (2a) in the first striking region (1) and the second striking region (2) of the striking mat (M) is formed on artificial turf having different lengths so as to correspond to the fairway and rough. The other sub-region (2b) in the second striking region (2) of the striking mat (M) can be formed of a material that can give a striking feeling like striking with sand. As described above, the striking mat (M) having a plurality of regions can be formed so as to be divided into three regions having different striking difficulty and / or striking feeling. In actual golf, there can be other terrain other than fairways, roughs and bunkers like water hazards, and there are various types of roughs and bunkers such as light roughs, heavy roughs, fairway bunkers and green bunkers. The multi-region hitting mat (M) can be formed in various shapes to reflect the various terrain attributes of the actual golf course, and is not necessarily limited to the structure shown in FIG. .. However, in the actual golf course, the weight of roughs and bunkers is higher in the non-fairway than in other areas, so in the following, the two sub-areas (2a, 2b) of the second hit area (2) are respectively. The rough area and bunker area are named, and the first and second hit areas (1, 2) are named the fairway area and the non-fairway area, respectively.

When a multi-area batting mat (M) is used, it provides a batting environment corresponding to various situations in which a virtual golf ball is placed on the screen. As illustrated in FIG. 10 (a), when the virtual golf ball (VB) in the screen is placed on the virtual fairway, the actual golf ball (RB) is placed in the fairway area (1). If you put it down and hit it, you can hit it in the hitting environment corresponding to the situation on the screen. In addition, as shown in FIG. 10 (b), when a virtual golf ball (VB) is placed in the virtual rough, the actual golf ball (RB) can be placed in the rough area and hit. , You can hit in a hitting environment that corresponds to the situation on the screen, and if a virtual golf ball (VB) is placed in the virtual bunker, as illustrated in (c) of Figure 10. If you place an actual golf ball (RB) in the area of the bunker and hit it, you can hit it in the hitting environment corresponding to the situation on the screen.

By using the striking mat (M) having a plurality of regions in this way, it is possible to provide a striking environment corresponding to various situations in which a virtual golf ball is placed on the screen. However, the user may intentionally or mistakenly hit the virtual golf ball (VB) on the screen in an environment that does not fit the situation. For example, as shown in FIG. 11A, the virtual golf ball (VB) is located in the virtual rough and the actual golf ball (RB) is placed in the fairway area of the striking mat. In the screen if the virtual golf ball (VB) is located in the virtual bunker and the actual golf ball (RB) is placed in the fairway area of the striking mat, as illustrated in 11 (b). The situation where the virtual golf ball (VB) is located and the environment where the actual golf ball (RB) of the striking mat is placed do not correlate with each other. In cases such as (a) and (b) in Fig. 11, the user must move the actual golf ball (RB) of the hitting mat to the rough area and the bunker area, respectively, and then hit the ball. It is also possible to hit the actual golf ball placed in the fairway area without moving the actual golf ball due to a mistake or mistake.

Since the hit feeling and hit difficulty on the fairway, rough, and bunker are different, the user can hit on a hit mat that has a hit difficulty corresponding to the hit difficulty in the area where the virtual golf ball (VB) is placed on the virtual golf course. Placing an actual golf ball (RB) in the area of and hitting it can be a fair play. Referring to the case illustrated in FIG. 11 (a), the virtual golf ball (VB) is placed on the screen in the virtual rough, so that the user can actually put the actual golf ball (VB) in the rough area of the batting mat to accommodate. You have to put a golf ball (RB) and hit it, but in reality, you put an actual golf ball (RB) in the fairway area, which is less difficult to hit than the rough area, so it is harder to hit than originally. It hits at a low degree and can be regarded as unfair. In this way, adjustment steps can be applied as a kind of penalty for unfair play.

Specifically, when the virtual golf ball (VB) is on the virtual fairway and the actual golf ball (RB) of the hitting mat is in the fairway area, the ball is hit ((a) in FIG. 10), the calculation step. When the flight distance of 100 is calculated, this becomes the final flight distance without applying the adjustment step. In comparison, if the virtual golf ball (VB) is in the virtual rough and the actual golf ball (RB) on the striking mat is in the fairway area, the ball is hit ((a) in FIG. 11) in the calculation step. Once the flight distance of 100 is calculated, the adjustment step is applied to reduce the final flight distance to 90 (adjustment rate is -10%). Also, when the virtual golf ball (VB) in the screen is in the virtual bunker and the actual golf ball (RB) of the hitting mat is in the fairway area, the ball is hit ((b) in FIG. 11). When the flight distance of 100 is calculated in the step, the adjustment step is applied to reduce the final flight distance to 80 (adjustment rate is -20%). The reduction rate of flight distance (10%) when the virtual golf ball (VB) is located in the virtual rough is larger than the reduction rate (20%) of the flight distance when the virtual golf ball (VB) is located in the virtual bunker. The reason for the small size is that since the difficulty of hitting with a bunker is higher than the difficulty of hitting with a rough, it is highly possible that the hit with a bunker will reduce the flight distance more than the hit with a rough. However, this is just an example of setting the reduction rate of the flight distance, and the reduction rate of the flight distance can be set by a method different from the method described here.

Similar to the case of using a single area striking mat, when using a multi-region striking mat, the flight distance can be increased in the adjustment step. Specifically, when the virtual golf ball (VB) in the screen is on the virtual fairway and the actual golf ball (RB) on the hitting mat is in the fairway area, the ball is hit ((a) in FIG. 10). When the flight distance of 100 is calculated in the calculation step, the adjustment step can be applied to increase the final flight distance to 120 (the adjustment rate is + 20%). In comparison, if the virtual golf ball (VB) is in the virtual rough and the actual golf ball (RB) on the striking mat is in the fairway area, the calculation step is performed ((a) in FIG. 11). Once the flight distance of 100 is calculated, the adjustment step can be applied to increase the final flight distance to 110 (adjustment rate is + 10%). Also, if the virtual golf ball (VB) is in the virtual bunker and the actual golf ball (RB) on the hitting mat is in the fairway area ((b) in Fig. 11), the calculation step is 100. Once the flight distance is calculated, the adjustment step can be applied to slightly increase the final flight distance to 105 (adjustment rate is + 5%), or the adjustment step can be omitted to maintain the flight distance of 100 in the calculation step. (Adjustment rate is 0%). Here, the rate of increase in flight distance is greatest when the virtual golf ball (VB) is located on the virtual fairway, and is intermediate when the virtual golf ball (VB) is located on the virtual rough, and the virtual golf ball (VB). ) Is located in the virtual bunker, which is the smallest example. This is in consideration of the fact that the difficulty of hitting increases in the order of fairway, rough, and bunker. However, this is an example of setting the increase rate of the flight distance, and the increase rate of the flight distance can be set by a method different from the method described here.

The above is the basis for determining the applicability of the adjustment step or the flight distance adjustment rate in the adjustment step (considering the characteristics of the terrain on which the virtual golf ball is placed in the screen, and additionally hitting multiple areas. Considering the area where the actual golf ball is placed when hitting on the mat) was explained. The following describes an example of applying the adjustment step due to other factors such as the slope, height, distance to the hole cup, etc. of the area where the golf ball is located in the screen.

12 to 14 are diagrams for explaining an example in which the adjustment step can be applied depending on the inclination, height, and distance from the hole cup in the area where the golf ball is placed in the screen.

Referring to FIG. 12, the final target point is the virtual hole cup (HC) in the play for a specific hole of the virtual golf course. Therefore, from the user's point of view, the distance between the virtual golf ball (VB) hit by the user and the virtual hole cup (HC) is important information that must be checked during play. In this connection, the virtual golf ball (VB) is in the first position (P1), which is the first distance (D1) away from the virtual hole cup (HC), and the virtual golf ball (VB) is virtual. Suppose that the ball is in the second position (P2), which is separated from the hole cup (HC) by a second distance (D2) different from the first distance (D1). When applying an adjustment step that additionally increases the flight distance to the calculation step, the flight distance increased by the adjustment step can be adjusted so as to be changed according to the distance from the virtual hole cup (HC). For example, when the first distance (D1) is larger than the second distance (D2), the flight distance increase rate at the first position (P1) is larger than the flight distance increase rate at the second position (P2). Adjust to. When you are far from the virtual hole cup (HC), aim for a long hit so that you can get as close to the hole cup as possible. Therefore, it is very beneficial for the user to increase the flight distance when hitting at a state far away from the virtual hole cup (HC). However, in the state close to the virtual hole cup (HC), the actual benefit of increasing the flight distance is not relatively large because the elaborate hit for hole-in of the golf ball is important. Therefore, depending on the distance from the virtual hole cup (HC), it is useful for the user to increase the rate of increase in the flight distance as the distance increases. However, it is not always necessary to use such a method (for the distance from the virtual hole cup (HC), the farther the distance is, the larger the increase rate of the flight distance is), and the virtual hole cup ( The closer the distance from HC), the greater the rate of increase in flight distance. Further, in order to increase the difficulty of playing screen golf, it is possible to reduce the flight distance in the adjustment step depending on the distance from the virtual hole cup (HC).

Referring to FIG. 13, the point on the screen where the virtual golf ball (VB) is placed has various slopes. Therefore, as illustrated in FIG. 13 (a), the virtual golf ball (VB) is located at a horizontal position on the virtual golf course, or as illustrated in FIG. 13 (b), the virtual golf ball. (VB) can be located on the slope of a virtual golf course. In actual golf, if the landing point is a horizontal point or a slope point, the next hit must be performed with the golf ball placed at the horizontal point or the slope point. The batting mat in screen golf is always horizontal, and it is difficult to experience the feeling of hitting and the difficulty of hitting on a slope. In general, hitting at a horizontal point is easier than hitting at a slope, so assuming that you swing under the same conditions, the hitting distance at a horizontal point is longer than the hitting distance at a slope. be able to. Taking these points into consideration, when the virtual golf ball (VB) on the screen is hit while being placed at the horizontal plane point ((a) in Fig. 13), the flight distance is 100 in the calculation step. When is calculated, it is maintained at the final flight distance without applying the adjustment step, and when the virtual golf ball (VB) in the screen is hit while being placed on the inclined point (Fig. 13 ((Fig. 13)). In b)), when the flight distance of 100 is calculated in the calculation step, the adjustment step can be applied to reduce the final flight distance to 90 (adjustment rate is -10%). The rate of decrease in flight distance when hitting at an inclined point can be determined by considering various factors such as the inclination angle and the inclination direction. It is also possible to increase the flight distance instead of decreasing the flight distance depending on the horizontal point / slope point. For example, when a virtual golf ball (VB) on the screen is hit at a horizontal point ((a) in FIG. 13), if a flight distance of 100 is calculated in the calculation step, an adjustment step is applied. Then, when the final flight distance is increased to 120 (adjustment rate is + 20%) and the golf ball in the screen is hit while it is at an inclined point ((b) in Fig. 13), the calculation step is used. Once the flight distance of 100 is calculated, the adjustment step can be applied to increase the final flight distance to 110 (adjustment rate is + 10%). Alternatively, when reducing / increasing the flight distance by a horizontal point / slope point, the flight distance is reduced in certain cases and the flight distance in other cases without applying only one of the decrease or increase. It can also be used in combination with increasing / decreasing the flight distance as in increasing.

Referring to FIG. 14, when a user plays a virtual golf course of a specific hole, the height of the virtual golf course is not constant as a whole and varies depending on the position. Considering that the height is not constant depending on the position, the flight distance adjusted by the position can be changed in the adjustment step. For example, in a virtual golf course, the height at the first position (P1) is the first height (H1), and the height at the second position (P2) is the second height different from the first height (H1). If (H2), when applying the adjustment step, adjust so that the adjusted flight distance changes depending on the height of the position where the virtual golf ball (VB) is placed. Specifically, when the second height (H2) is higher than the first height (H1), the flight distance increase rate at the second position (P2) is the flight distance increase rate at the first position (P1). Can be made larger than. When a golf ball flies from a high point to a low point, the flight path of the golf ball may increase by the difference between the high point and the low point. It can be configured so that the higher the height of the point where the virtual golf ball (VB) is placed, the larger the flight distance increase rate. However, such a method is not always applied, and the lower the height of the point where the virtual golf ball (VB) is placed, the larger the flight distance increase rate can be set. Further, in order to increase the difficulty of playing screen golf, it is possible to configure the flight distance to decrease in the adjustment step depending on the height of the point where the virtual golf ball (VB) is placed.

As described above, according to the virtual golf device of the present invention, factors such as the topographical attributes of the point where the virtual golf ball is placed on the screen, the inclination and height of the point, and the distance from the hole cup are factors. It is possible to apply an adjustment step for reducing or increasing the flight distance calculated in the calculation step based on. Decreasing the flight distance in the adjustment step is disadvantageous to the user, and increasing the flight distance in the adjustment step is advantageous to the user. Golf is a sport in which a golfer who has a small total number of hits to hole in a hole cup wins, and as the flight distance increases, the golf ball approaches the hole cup, so there is a possibility that the number of hits can be reduced. Will be higher. Therefore, decreasing the flight distance is disadvantageous to the user, and increasing the flight distance is advantageous to the user. Adjusting to reduce the flight distance and making it disadvantageous to the user has the effect of increasing the difficulty of screen golf and inspiring a high-level user to take on the challenge. Adjusting to increase the flight distance to the advantage of the user has the effect of lowering the difficulty level of screen golf and lowering the entry barrier of screen golf for low-level users. Therefore, the golf ability of the user can be used as a basis for determining whether or not the flight distance can be increased / decreased and how much the flight distance is increased / decreased. The golf ability of the user can be calculated based on the play information of the user. Since screen golf courses are usually operated by membership, a login step is performed to confirm the identity of the user before providing the screen golf service. A screen golf service is provided with the user's identity confirmed by the login step, and while the identified user plays screen golf, the user's play record is stored in a database (drawing code 33 in FIG. 2). Can be stored in its user information at). By utilizing the play records stored in the database, it is possible to determine the level indicating the user's golf ability. If the user's level is utilized when applying the adjustment step, the database that stores the information related to this can be formed in various structures. An example of the database structure will be described with reference to the drawings.

15-18 show various detailed structures of the database of FIG.

Referring to FIG. 15, in the database, different storage is assigned to each user for a plurality of users, and various information is stored in the storage assigned to each user. For example, if there are users A and B, the database separates the storage for storing user A's information (P1) and the storage for storing user B's information (P2) for each user. The area of is provided with a user's personal information DB, a user's play information DB, a user's level information DB, and the like. The user's personal information DB stores the user's personal information and can be used for login steps and the like. The user's play information DB is to store the record played by the user, and can be updated every time the user plays. The user level information DB records the level evaluated by the user, and can be provided for the user to view. The user's level is not fixed and can be changed as the user's play record is updated.

The user level can be calculated based on the data stored in the user's play information DB. The user's play information DB may include the number of plays, the play time, the play record, and the like. The larger the number of plays and the longer the play time, the more you have played than other users. In general, the more you play, the better your ability and the higher your level. In connection with the user's play record, for example, average at bat, driver distance, fairway settlement rate, green accuracy, average number of putts, etc. can be stored, and at least one of these can be leveled. Can be used for calculation.

The average number of strokes is the average value of the number of strokes recorded by the user. Generally, in a golf course consisting of a total of 18 holes, the total number of strokes is 72, and a user with about 70 to 80 strokes can be recognized as an expert. The average number of strokes can be seen as an indication of a golfer's ability from a comprehensive perspective. The driver flight distance indicates the distance that the golf ball flies by the driver shot. The flight distance does not increase simply because the force is good, but it is affected by technical aspects such as the swing posture and the accuracy of the swing at the impact of the golf ball, so the longer the flight distance, the more the user level. Can be seen as high. The fairway settlement rate is a numerical value indicating the rate at which a driver's tee shot is settled on the fairway (without falling into the rough or bunker). The green accuracy indicates the number of times a golf ball has landed on the green below the specified number of strokes in "percentage (%)". The average number of putts indicates the average number of times puts are made to the hole-in in the on-green state. The driver's flight distance indicates the long hitting ability of the driver shot, the fairway landing rate and green accuracy indicate the accuracy of the shot, and the average number of putts indicates the accuracy of the putt. The average number of strokes indicates the golfer's ability from a comprehensive point of view, and the driver's flight distance, fairway settlement rate, green accuracy, average number of putts, etc. indicate the golfer's ability in a specific aspect, so combine these appropriately. The user's level can be calculated accurately.

If the user's level is calculated as described above, this can be saved in the user's level information DB. In addition, the user level information DB can store data on how to process in the adjustment step based on the user level. For example, as shown in FIG. 15, when it is determined that a specific user (user A) is a beginner and needs to reduce the difficulty level of play, it is determined that the flight distance is to be increased in the adjustment step. The content data can be stored in the user's level information DB, and even the data about how much the flight distance is to be increased can be stored in the user's level information DB. A specific user (User B) does not need to give an advantage because it is a high level, but if it is judged that it is necessary to increase the difficulty of playing, it is judged that the flight distance is to be reduced in the adjustment step. The data can be stored in the user's level information DB, and even the data about how much the flight distance is reduced can be stored in the user's level information DB.

With reference to FIG. 16, the database can store user information in a manner different from that described above. That is, as shown in FIG. 16, the storage is configured so as to be distinguished by the user's level without forming the user's level information DB separately. For example, if you have users A, B, C, and D, users A and B belong to level 1, and users C and D belong to level 10, then the database has an area for users that belong to level 1 ( The area (N1) and the area for users belonging to level 10 (N10) are separated from each other, and the area for storing user A's information (P1) and the area for storing user B's information (P2) are the above-mentioned level 1. The region (P3) for storing user C information and the region (P4) for storing user D information are formed together in the region (N1) of the above level 10. Level 1 is the lowest level, the higher the number, the higher the level, the user belonging to level 1 lowers the difficulty of playing considering that it is a beginner, and the user belonging to level 10 is an expert When trying to increase the difficulty level of play in consideration of the fact that there is, the data of the content that the user belonging to level 1 judges as the target to increase the flight distance in the adjustment step is the area for the user belonging to level 1. It is stored in (N1) that the data of the content that the user belonging to level 10 determines to increase the flight distance in the adjustment step is stored in the area (N10) for the user belonging to level 10. it can. In addition, data on how much distance is increased or decreased can be stored in the area for level 1 users (N1) and the area for level 10 users (N10), respectively. it can.

It is configured so that the user can set whether or not the flight distance can be increased / decreased in the adjustment step, the value of the adjustment rate (item of how much the flight distance is increased / decreased), or whether or not the flight distance adjustment step can be performed. You can also do it. Referring to FIG. 17, the database allocates different storage for each user to multiple users. Various information is stored in the area allocated to each user. For example, if there are users A and B, in the database, the area for storing user A's information (P1) and the area for storing user B's information (P2) are separated from each other for each user. The area of is provided with a user's personal information DB, a user's play information DB, a flight distance setting information DB, and the like. Compared with the database structure explained with reference to FIG. 15, the user's personal information DB and the user's play information DB are the same as each other, but the flight distance setting information DB is provided instead of the user's level information DB. There is a difference. The contents set by the user are stored in the flight distance setting information DB. In order to make the above settings, the user can input whether or not the flight distance can be increased / decreased and the adjustment rate in the adjustment step through the input unit (see drawing reference numeral 20 in FIG. 1), and the input data is skipped. It can be stored in the distance setting information DB.

Allow the user to set whether or not the flight distance can be increased / decreased in the adjustment step, the value of the adjustment rate (item of how much the flight distance is increased / decreased), or whether or not the flight distance adjustment step can be performed. Alternatively, it can be determined automatically according to the user's level. Referring to FIG. 18, the database allocates storage for each user to a plurality of users, and various information is stored in the storage assigned to each user. The area for each user includes a user's personal information DB, a user's play information DB, a user's level information DB, a flight distance setting information DB, and the like. Compared with the structure of the database described with reference to FIG. 15, the user's personal information DB, the user's play information DB, and the user's level information DB are the same as each other, but the flight distance setting information DB is further provided. There is a difference. In the flight distance setting information DB, it is possible to save the data input by the user for the increase / decrease of the flight distance and the increase / decrease of the flight distance in the adjustment step. In this case, in the adjustment step, the adjustment step is performed with priority referring to the contents of the flight distance setting information DB, and the user separately performs the processing contents in the adjustment step (whether or not the flight distance can be increased / decreased and the flight distance is determined. If you do not enter (increase / decrease, etc.), you can perform the adjustment step by referring to the user's level information DB.

As mentioned above, this method of operation provides high-level users with the opportunity to play at high difficulty and low-level users at low difficulty through adjustment steps according to the user's level. By providing an opportunity to play golf, it has the effect of inspiring the challenging spirit of playing with high difficulty for advanced players, and lowering the entry barrier of golf to allowing lower players to enjoy screen golf. In addition, by allowing the user to set the adjustment method by himself / herself, it provides an opportunity to play in any method that the user prefers.

In the above, various methods for determining the applicability of the adjustment step and the requirements and criteria for determining the adjustment rate when applying the adjustment step have been described with reference to FIGS. 6 to 18, but the above method is used alone. Or they can be combined with each other and used in combination.

As an example of combined use, apply the adjustment step according to the distance between the virtual golf ball and the virtual hole cup, and apply the adjustment step according to the inclination of the point where the virtual golf ball is placed. Can be used in combination with things. Specifically, depending on the distance between the virtual golf ball and the virtual hole cup,'"20% increase in flight distance" occurs as a factor for adjusting the first flight distance, and the virtual golf ball is placed. If "10% reduction in flight distance" occurs as the second flight distance adjustment factor due to the inclination of the point, the first and second flight distance adjustment factors are combined and finally 10% in the adjustment step. The flight distance can be increased.

Also, as another example of combined use, applying an adjustment step according to the inclination of the point where the virtual golf ball is placed can be used in combination with reflecting the level of the user. Assuming that the beginner hits at a point with a specific slope and the expert hits at a point with the same slope, the hit result of the beginner and the expert is the same (for example, of a golf ball after hitting). If the physical condition is the same for both beginners and experts), and the flight distance adjustment rate due to the inclination of the point where the virtual golf ball is placed in the adjustment step is + 10%, for beginners, the above +10 Add the flight distance adjustment rate according to the user level (for example, + 10%) to% so that the total flight distance increases by 20% in the adjustment step, and for experts, the above + 10% depends on the user level. A flight distance adjustment rate (eg, -5%) can be added to finally increase the flight distance by a total of 5% in the adjustment step.

As described above, the applicability of the adjustment step and the requirements and criteria for determining the adjustment rate at the time of applying the adjustment step can be determined in a complex manner by combining various methods. Here, the case where the two methods are combined is given as an example, but more methods can be used in combination, and other methods not described here can be combined.
