Description

The present invention relates to a virtual golf device and a virtual golf system using the same, and more particularly to a virtual golf device having significantly improved reality in virtual golf play such as screen golf and a virtual golf system using the same.

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

An important point in the popularization of screen golf is whether or not it is possible to realistically reproduce actual golf. Screen golf reflects various things that are applied to real golf in order to realistically reproduce real golf. For example, an actual golf course has terrains with various attributes such as fairways, roughs, and bunkers, and the golf course on the screen also displays various terrains such as fairways, roughs, and bunkers. .. Further, in screen golf, a plurality of areas such as a fairway-compatible area, a rough-compatible area, and a bunker-compatible area are divided into a hit plate on which a golf ball is placed. Therefore, if the area where the golf ball is landed on the screen is rough, the user of the screen golf can land the golf ball roughly in the actual golf by placing the golf ball in the rough corresponding area on the hit plate and hitting it. You can experience the feeling of hitting a golf ball.

As mentioned above, reproducing an actual golf course in screen golf can be seen as a general feature that can be uniformly applied to all users of screen golf.

FIG. 1 is a schematic configuration diagram of a virtual golf device according to an embodiment of the present invention, FIG. 2 shows an example of a golf club selection screen displayed on the screen of the virtual golf device of FIG. 1, and FIG. 3 is a diagram. An example of a screen displayed on the screen after selecting a user's golf club in the virtual golf device of FIG. 1 is shown, and FIG. 4 shows a schematic structure of a storage unit in the virtual golf device of FIG.

Referring to FIG. 1, the virtual golf device according to the embodiment of the present invention has a striking plate (10), a control unit (20), a storage unit (30), a sensing unit (40), an input unit (50), and a sound unit ( 60), and the display unit (70).

The hit plate (10) is a place for hitting a golf ball, and the user is located at the hit plate (10) and hits a golf ball placed here.

The control unit (20) controls the overall operation of the components of the virtual golf device. For example, although not shown in the drawing, the striking plate (10) is provided with an auto tee that automatically provides a golf ball for striking, and the control unit (20) is described as described above when the user strikes. Control the auto tee to provide the golf ball with the auto tee. Further, the control unit (20) performs a calculation process for calculating the trajectory of the golf ball. In the calculation process, when the user hits a golf ball, the trajectory and / or the flight distance when the golf ball is assumed to fly at an actual golf course are calculated.

The storage unit (30) stores various data necessary for the operation of the virtual golf device, and also stores information about various golf clubs. The golf clubs include commercially available golf clubs used in the current market.

The sensing unit (40) senses a physical state such as the speed, moving direction, and rotation angle of the golf ball hit by the user. The sensing unit (40) includes a sensing means capable of sensing the physical state of the golf ball, and various sensors, cameras, and the like can be used as the sensing means. The cameras, sensing sensors, and the like can be used alone or together, or only one can be used, or a plurality of sensors can be used. The information sensed by the sensing unit (40) is transmitted to the control unit (20), and the control unit (20) executes the calculation process based on the transmitted information.

The input unit (50) is for receiving various information from the user, and a keyboard / mouse, a touch screen, or the like can be used. In screen golf, the user enters information such as when the user enters his / her ID and password to log in, when the user selects the golf course to play, the difficulty level, etc. In some cases, an input unit (50) is required at this time. The information input from the input unit (50) is transmitted to the control unit (20), and the control unit (20) processes the user's request based on the transmitted information. For example, when a user selects a specific golf course, the control unit (20) includes an image processing means for processing the image for necessary processing so that the golf course can be played. When the user selects a specific golf course, the image processing means can transmit and display the image of the selected golf course to the display unit (70). Further, when the user inputs personal information such as an ID and a password for logging in, the control unit (20) checks the input personal information and plays a role of deciding whether or not to approve the login.

The sound unit (60) includes an audio device such as a speaker, and plays a role of informing the user of the progress of the game and reproducing various sound effects due to the progress of the game.

The display unit (70) includes a beam projector (71) and a screen (72). The beam projector (71) projects the relevant image onto the screen (72) so that the golf course and golf ball are displayed on the screen (72), and the screen (72) displays the projected golf-related image. Provide to users. In the following, some objects displayed on the screen (72) can be expressed with the term "virtual". This means that it does not exist in the real world but is displayed on the screen (72). For example, "virtual golf course" means a golf course displayed on the screen (72), and "virtual golf ball" means a golf ball displayed on the screen (72).

The process of screen golf play in a virtual golf device having the above configuration is as follows. When the user hits a golf ball on the hit plate (10), the control unit (20) calculates the flight trajectory of the hit golf ball based on the detection information from the detection unit (40), and the screen (72) displays the flight trajectory. , Display an image of a virtual golf ball moving as calculated above. At this time, the virtual golf ball in the screen (72) flies according to the calculated trajectory, and then lands at a specific point on the virtual golf course in the screen (72), and the user uses the screen (72). While continuing to hit from the point where the virtual golf ball lands, the above process is repeated until the hole is made into the hole cup.

Referring to FIG. 2, the user can perform the golf club selection process before hitting the actual golf ball. During the selection process, the screen (72) displays information about the golf clubs stored in the reservoir (30). Golf clubs are classified and displayed according to their functions, such as drivers, woods, irons, hybrids, wedges, and putters. Commercially available golf clubs currently on the market can be displayed in the item of each club classified by function in this way. If a driver shot is required, the user can select the required driver golf club from the driver club item. Also, if an iron shot is required, the user can select the required iron golf club from the iron club item, and if another shot is required, the desired golf club can be selected from that item. can.

Referring to FIG. 3, when the user selects a golf club in the selection process, the selected golf club is displayed on the screen (72). For example, as illustrated in FIG. 3 (a), the screen (72) displays a window (W) displaying information about the playing user, which contains brief information about the user (W). Username, personal record, etc.) are displayed. In addition, the golf club selected by the user is displayed in the user window (W). The user can refer to the window (W) and play while confirming the golf club of his / her choice. Alternatively, as illustrated in (b) of Figure 3, the user's window (W) on the screen (72) displays only brief information about the user (such as the user name and personal records) and is selected by the user. The golf club (GC) can be displayed in more detail on the main part of the screen (72) (such as the center or bottom of the screen (72)). However, since the main use of the screen (72) is to display a virtual golf ball and a virtual golf course, the selected golf club (GC) image does not interfere with displaying a virtual golf course or the like. As such, the golf club (GC) displayed on the main part of the screen (72) is preferably displayed only for a certain period of time and then disappears.

Information about various golf clubs is stored in the reservoir (30) for the selection process. In addition, the storage unit (30) can store user information for individual users. Referring to FIG. 4, the storage unit (30) includes a storage area (I1) for golf club information and a storage area (I2) for user information. Information (I11, I12, ...) for each golf club is separately stored in the golf club information storage area (I1). Information for individual golf clubs (I11, I12, ...) includes image information, product information, spec information, and the like. The image information includes an overall image of the golf club or an image of the main part of the golf club such as a head or a shaft. The product information includes information such as a manufacturer, a date of manufacture (release date), a model name, a size, a weight, and a material. The spec information includes information such as a loft angle, a lie angle, a shaft strength, and a shaft torque (values of such spec information of a golf club are referred to as "club variables" in the present specification). Personal information, play record information, golf club information, etc. are stored in the storage area (I2) for user information. The personal information includes personal information such as a user's gender, age, height, weight, and history. The play record information is a cumulative record of the user playing on the screen golf course, and includes an average number of hits, an average flight distance, an average speed of a hit ball, and the like. The golf club information includes information such as a golf club selected by the user in the selection process and a golf club used by the user himself / herself.

FIG. 5 is a schematic configuration diagram of a virtual golf device according to another embodiment of the present invention.

Referring to FIG. 5, the virtual golf device according to the present embodiment includes a striking plate (10), a control unit (20), an input unit (30), a sensing unit (40), a beam projector (71) and a screen (72). A display unit (70) including the above is provided. A computer device capable of driving predetermined software is used as the control unit (20), an input device such as a keyboard or a mouse is used as the input unit (30), and an input device such as a keyboard or mouse is used as the input unit (40). Sensing means such as a camera can be used. Since such a configuration is not significantly different from the configuration in the embodiment described with reference to FIG. 1, detailed description thereof will be omitted. Although not shown in the drawings, the storage unit in the embodiment described with reference to FIG. 1 can be provided in the internal storage device of the control unit (20), and the sound unit is also provided in a speaker or the like separately. Can be done. Compared to the embodiment described with reference to FIG. 1, the virtual golf device according to this embodiment further includes an auxiliary display (80). As the auxiliary display (80), a monitor, a kiosk, or the like can be used. Various information can be displayed on the auxiliary display (80) for the convenience of the user. For example, the auxiliary display (80) may display golf club information (see FIG. 2) for performing the selection process of selecting a golf club. The screen (72) and the auxiliary display (80) can all display and provide various information and images to the user, but the screen (72) provides the main image related to screen golf, and the auxiliary display (80) provides the user. The screen (72) and the auxiliary display (80) can play different roles by allowing the necessary auxiliary information to be displayed. According to this embodiment, a screen (72) that provides a main image in screen golf and an auxiliary display (80) that provides auxiliary information necessary for the user are provided according to the type of the object to be displayed. It has the effect of improving the convenience of.

When performing the selection process, the user can actually hit the golf ball with the golf club of his choice, or hit the golf ball with a golf club different from the golf club of his choice. In the virtual golf device of the present invention, the user can play in various ways depending on whether or not the golf ball is hit by the same golf club as the selected golf club. Specifically, the virtual golf device of the present invention provides a first play mode of hitting with the same golf club as the selected golf club and a second play mode of hitting with a golf club different from the selected golf club. do. The first and second play modes make a difference in the calculation process for calculating the trajectory of a golf ball. Hereinafter, the first and second play modes will be described.

FIG. 6 is a diagram for explaining an example of a calculation process in the first play mode when the first and second play modes are applied to the virtual golf device according to the embodiment of the present invention. FIG. 7 is a diagram for explaining an example of a calculation process in the second play mode when the first and second play modes are applied to the virtual golf device according to the embodiment of the present invention. FIG. 8 shows an example of a screen displayed on the screen when the first and second play modes are applied. FIG. 9 shows an example of an interface device that allows the user to select a play mode when the first and second play modes are applied. FIG. 10 shows an example of a screen screen according to a modified example of the first and second play modes.

Referring to FIG. 6, in the calculation process in the first play mode, the trajectory of the golf ball (B) is calculated based on the physical state of the golf ball (B) hit by the user. do. The physical state of the golf ball (B) is sensed by the sensing unit (40). The physical state can be grasped by various physical parameter values. The above-mentioned physical parameters are very diverse in type, and the movement of the actual golf ball (B) hit is also fluctuated with time and time, so when calculating the trajectory in consideration of all of these. The calculation process becomes very complicated. Therefore, for convenience of explanation, of the golf ball (B) using a very simple model using only some of the various physical parameters of the golf ball (B) (eg, the speed and direction of movement of the golf ball). The trajectory calculation process will be described.

As illustrated in FIG. 6, when the user hits the golf ball (B), the golf ball (B) flies at a predetermined speed (V1) and direction (θ1). Here, the velocity (V1) is the initial velocity immediately after the golf ball (B) is hit, and the direction (θ1) is an angle inclined with respect to the horizontal plane as a factor indicating the direction of flight by the hit. In the calculation process, it is calculated what kind of trajectory (T1) the golf ball (B) has when it moves with the physical parameters (V1, θ1). After extracting the parameters indicating the physical properties of the golf ball (B) in this way, the calculation process in the first play mode is to calculate the locus (T1) by using the parameters as they are. In short, the actual golf ball (B) hit by the user is used as it is without changing the physical state. In the first play mode, the golf ball is hit with the same golf club as the golf club selected by the user, so that the "user's selection condition" and the "actual hitting condition" correspond to each other, and in the first play mode. The calculation process of is to follow the usual calculation method as it is when both conditions correspond.

On the other hand, in the second play mode, the golf ball is hit by a golf club different from the golf club selected by the user, and the "user's selection condition" and the "actual hitting condition" do not correspond to each other. In the calculation process in the second play mode, a method different from the normal calculation method is applied in order to compensate for the discrepancy between the two conditions. For example, the trajectory of the golf ball is calculated by partially changing the parameter indicating the physical properties of the golf ball (B) grasped from the sensing unit (40) in the calculation process. Specifically, referring to (a) of FIG. 7, it is assumed that the golf ball (B) hit by the user has a predetermined velocity (V1) and direction (θ1). Assuming that the first locus (T1) is calculated from the physical parameters (V1, θ1), in this method, the velocity value of the physical parameter of the golf ball is deformed to obtain the deformation value “V2” as follows. To calculate.
V2 = f (V1, α)
In this way, when the deformation value "V2" is calculated from the first velocity value (V1), the locus (T2) is calculated from the deformed velocity (V2) and the direction value (θ1).
α is a variable that represents the difference in the club variable due to the difference between the specifications of the golf club selected by the user and the specifications of the golf club actually used (α = Δ (specs of the selected golf club-specs of the golf club used). )). f (V1, α) is a function or mathematical formula with V1 and α as variables. For example, if there is a difference in shot intensity between the selected golf club and the golf club used, and there is a uniform velocity difference of α for the same swing, then f (V1, α) is , In a simple form
f (V1, α) = V1 + α
become. According to such a form, the velocity V1 of the hit golf ball (B) increases or decreases according to the value of α, V1 is changed to V2, and the calculation process based on the changed V2 The trajectory of the golf ball changes. When the user selects golf club A and actually hits using golf club B, V1 and θ1 show the hitting result by golf club B, but when the calculation process is performed using only V1 and θ1. The act of the user selecting golf club A cannot be reflected in the calculation process. However, after deriving a function or formula such as f (V1, α) taking into account the club variables of golf club A, thereby changing the speed value from V1 to V2, then calculating based on V2, θ1. When performing the process, the result of the user's selection of golf club A can be reflected in the trajectory of the golf ball hit by the user.

For example, the golf club A selected by the user is a golf club that the user personally owns, and the golf club B that the user uses when actually hitting is provided in the screen golf course where the virtual golf device is installed. Suppose it is a golf club that has been played. Since the user hits the golf ball using his / her own golf club A in the actual golf course, he / she also hits the golf ball using his / her own golf club A when hitting the golf ball at the screen golf course. You are likely to want that. It is possible to bring and use your own golf club when playing at the screen golf course, but it is not easy to visit the screen golf course with your own golf club at all times, so go to the screen golf course. It is possible to use a golf club that is different from your own golf club. In such a case, the user is forced to use the golf club provided in the screen golf course, but knows the hit result when hitting with his own golf club. In consideration of such a point, the virtual golf device according to the embodiment of the present invention provides a second play mode for calculating the trajectory of a golf ball in a state assuming that a golf club selected by oneself is used. This allows golf club A to be used when golf club B is used when considering club variables due to various specifications of golf club A selected by the user and golf club B actually used by the user. When it is judged that the speed of the hit golf ball increases by a predetermined fluctuation (α),
f (V1, α) = V1 + α
The velocity value (V2) transformed from the actual velocity value (V1) is derived from the actual velocity value (V1), and the trajectory of the golf ball is calculated based on this.

Due to the difference in specifications between the golf club A selected here and the golf club B used, f (V1, α) becomes a more complicated form rather than a simple form in which a predetermined variation (α) is added. There is a possibility that it will be. Since the spec difference between golf clubs is very diverse, it is possible that the formula is not just a formula as described above, but a more complicated formula. Can be created and applied.

Not only the velocity can be changed, but other variables can be changed to calculate the trajectory of the golf ball. For example, as shown in FIG. 7 (b), it is assumed that the golf ball (B) hit by the user has a predetermined velocity (V1) and direction (θ1). Assuming that the first locus (T1) is calculated from the physical parameters (V1, θ1), the deformation value “θ2” is calculated by transforming the direction value of the physical parameter of the golf ball as follows. ..
θ2 = f (θ1, α)
As described above, when the deformation value "θ2" is calculated from the first direction value (θ1), the locus (T2) is calculated from the velocity (V1) and the deformation value (θ2).
f (θ1, α) is a function or mathematical formula with θ1 and α as variables. f (θ1, α) is in a simple form
f (θ1, α) = θ1 + α
become.

Since the spec difference between golf clubs is very diverse, it is possible that the formula is not just a formula as described above, but a more complicated formula. You can create and apply complex formulas.

In this way, the parameters indicating the physical properties of the golf ball (B) are extracted, and at least some of the parameters are based on the spec difference between the golf club selected by the user and the golf club used by the user for hitting. After artificially transforming, calculating the locus (T2) based on this is the calculation process applied to the second play mode. Here, only two physical parameters, speed value and direction value, are explained as an example, but this is only a brief explanation to help understanding, and various physics can be used to calculate the trajectory of a golf ball. Since parameters (spin direction of golf ball, spin value, etc.) can be used, it is also possible to calculate the changed trajectory of the golf ball by changing other physical parameters other than the speed value and the direction value.

Referring to FIG. 8, when multiple users play screen golf, each user selects one of the first play mode and the second play mode before starting the play. You can select and play. For example, suppose User A and User B play together, User A prefers the first play mode, and User B prefers the second play mode. If User A and User B select the first and second play modes, respectively, the screen (72) displays User A's window (W1) when User A plays, as illustrated in FIG. And when User B plays, User B's window (W2) is displayed on the screen (72). In the user window (W1, W2), personal information (ID, name, nickname, etc.) that can identify the user, past records of the user, current play status, etc. are easily displayed. In addition, the user's window (W1, W2) shows what play mode the user is playing in, and the user refers to his window (W1, W2) and plays in what mode he is playing. You can check if you are doing it. After confirming the play mode and before starting the current hit, the user can play while maintaining the set mode, or change the set mode using various input means and play. While doing so, you can enjoy screen golf the way you like.

Referring to FIG. 9, the virtual golf device can use the input means (11) for selecting the first and second play modes. The input means (11) is arranged in the vicinity of the hit plate (10), and a user located in the hit plate (10) for hitting a golf ball can use the nearby input means (11). You can easily choose between the first and second play modes at any time. For example, the input means (11) has a "first button (11a)" for selecting the first play mode and a "second button (11b)" for selecting the second play mode. The user can easily select either the first or second play mode by stepping on either the first button (11a) or the second button (11b). The input means (11) includes not only a button for selecting the first and second play modes, but also other buttons (11c) for inputting commands frequently used by the user while playing screen golf. There can be. For example, the button (11c) can play a role in adjusting the angle and position of the screen in the screen.

The input means (11) is not mandatory and the user may select one of the first and second play modes using a normal input device such as a mouse or keyboard. can. Also, if there is no user selection, the virtual golf device can be made to automatically select one of the first and second play modes. For example, if the user skips the selection process and does not select a golf club, the first play mode is automatically selected, assuming that the user has selected the same golf club provided on the screen golf course. Can be configured to Or equipped with a golf club sensing means such as a camera to automatically and / or manually sense the golf club used by the user to hit the golf ball, and the golf sensed by the user's selected golf club and sensing means. After checking whether it is the same as the club, one of the first and second play modes can be automatically selected based on the result of the check.

As described above, depending on whether a golf club is selected and hit with the same golf club as the selected golf club, the player plays in the first or second play mode, and is calculated in the calculation process by the first and second play modes. The method of changing the trajectory of a golf ball has been explained. According to this method, when the user selects his / her own golf club, especially under the second play mode, the user feels as if he / she hits with his / her personal goods at the screen golf course. As a result, the reality of screen golf can be improved. Alternatively, under the second play mode, the user can select an unknown golf club that he has never actually used, in which case the user preliminarily responds to the feel of the unknown golf club. You can experience it.

Not only the first and second play modes, but also a modified play mode is possible. For example, when the golf club selected by the user and the golf club used by the user are different, the first trajectory is calculated in the calculation process in the first play mode method (the trajectory is calculated without changing the physical parameters of the golf ball). Is calculated, and it is assumed that the second trajectory is calculated in the calculation process in the second play mode method (the trajectory is calculated by changing the physical parameters of the golf ball). Referring to (a) of FIG. 10, the screen (72) (or the auxiliary display (80) of FIG. 5) displays both the first locus (T10) and the second locus (T20). As a result, the user can directly compare the hit result of the golf club that he / she actually used for hitting with the hit result of the golf club of his / her choice. Alternatively, the user can select multiple golf clubs in the selection process, for example, in the selection process, the user selects the first golf club, which is his personal golf club, and the second golf club, which he does not own, and in fact. Assuming that a golf club different from the first and second golf clubs provided in the screen golf course is used for hitting, the calculation process (first trajectory) in the first play mode method and the first and first golf courses are used. After executing the calculation process (second and third trajectories) in the second play mode method for the golf club of 2, the first locus (T10) and the second locus are as shown in FIG. 10 (b). (T21) and the third locus (T22) can be displayed together. As a result, the user directly compares the difference between the hit result by the golf club actually used (T10), the hit result by the golf club he / she owns (T21), and the hit result by the golf club he / she does not have (T22). You can figure out what golf clubs are more suitable for you. In particular, when a user has an intention to purchase a new golf club because he / she does not like the golf club he / she currently owns, he / she selects and hits various golf clubs as the second golf club. Later, you can compare the results and decide what kind of golf club to buy.

FIG. 11 shows an example of a screen screen that provides information on a store while recommending a golf club to a user.

Previously, it was stated that the user can judge the golf club that suits the user by selecting various golf clubs and comparing the hit results, but such a judgment is made by the control unit (20). Can be done. When the user hits, the calculation process under the second play mode can be applied to calculate the hit result when using various golf clubs, and this calculation result is analyzed to control the control unit ( 20) can find and recommend suitable golf clubs to users. In addition, the control unit (20) can utilize the information stored in the storage unit (30) for the recommendation of the golf club. As explained with reference to FIG. 4, the storage unit (30) stores user information (personal information, play record information, etc.) and golf club information (spec information, etc.), and uses this. It is possible to recommend a golf club suitable for the user. In the recommendation step, one golf club may be recommended or a plurality of golf clubs may be recommended. When recommending multiple golf clubs, if the user's suitability is different for each golf club, this can be displayed numerically. For example, if the goodness of fit for the user of A golf club of XXX company is 95 and the goodness of fit for the user of B golf club of △△△ company is 90, the goodness of fit is as shown in FIG. It is displayed as a numerical value. In addition to recommending golf clubs, if you provide information on the dealers of the recommended golf clubs, you can immediately purchase the golf clubs that the recommended user likes. When there are a plurality of dealers and the prices are different, the relevant information can be provided so that the prices of the plurality of dealers and each dealer can be compared. Golf club recommendations and dealer information can be displayed on screens, auxiliary displays and the like.

13 is a schematic configuration diagram of a virtual golf device according to an embodiment of the present invention, FIGS. 14 to 20 show operation processes applicable to the virtual golf device of FIG. 13, and FIGS. 21 and 21 show the first and second steps. An example of an interface device that allows a user to select a play mode when the second play mode is applied is shown.

Referring to FIG. 13, the virtual golf device (100) according to the embodiment of the present invention includes a striking plate (110), a control unit (120), a storage unit (130), a sensing unit (140), and an input unit (150). Includes sound section (160) and display section (170).

The hit plate (110) is a place for hitting a golf ball, and the user hits a golf ball located at the hit plate (110) and placed here.

The control unit (120) performs a calculation process for calculating the trajectory of the golf ball. In the calculation process, when the user hits a golf ball, the trajectory and / or the flight distance when the golf ball is assumed to fly at an actual golf course are calculated. In addition, the control unit (120) can provide the user with various play options while controlling the overall operation of the components of the virtual golf device. For example, the control unit (120) provides the user with the first and second play modes, and the user can select and play one of the above two play modes. In the first play mode, the user can use his or her personal golf ball, and in the second play mode, the user can use the golf ball automatically provided to the batting plate (110). .. Although not shown in the drawings, the striking plate (110) is provided with a golf ball providing means that automatically provides a striking golf ball. In the first play mode, the control unit (120) controls the golf ball providing means so as not to operate, and the user places the golf ball prepared by himself / herself on the hit plate (110) at the time of hitting. Hit this. Some screen golf users may prefer to hit the golf ball they normally use rather than the golf ball provided by the screen golf course. , You can prepare a personal golf ball that you normally use through the first play mode and use it for hitting. In the second play mode, the user does not need to prepare a golf ball separately, and the control unit (120) so that the golf ball is provided to the hit plate (110) at the time when the user hits. Control the means of providing golf balls.

The storage unit (130) stores various data necessary for the operation of the virtual golf device, and also stores information about various golf balls. The golf ball information includes information on commercially available golf balls used in the current market.

The sensing unit (140) senses a physical state such as the speed, moving direction, and rotation angle of the golf ball hit by the user. The sensing unit (140) includes a sensing means capable of sensing the physical state of the golf ball, and various sensing sensors, cameras, and the like can be used as the sensing means. The cameras, sensing sensors, and the like can be used alone or together, or only one can be used, or a plurality of sensors can be used. The information sensed by the sensing unit (140) is transmitted to the control unit (120), and the control unit (120) performs a calculation process based on the transmitted information.

The input unit (150) is for receiving various information from the user, and a keyboard / mouse, a touch screen, or the like can be used. In screen golf, the user enters information such as when the user enters his / her ID and password to log in, when the user selects the golf course to play, the difficulty level, etc. In some cases, an input unit (150) is required at this time. The information input by the input unit (150) is transmitted to the control unit (120), and the control unit (120) processes the user's request based on the transmitted information. For example, the user can select one of the above-mentioned first and second play modes through the input unit (150), and the control unit (120) automatically sets the hit plate (110) according to the user's selection. Provide or do not provide golf balls. Further, when the user inputs personal information such as an ID and a password for logging in, the control unit (120) checks the input personal information and plays a role of deciding whether or not to approve the login.

The sound unit (160) includes an audio device such as a speaker, and plays a role of informing the user of the progress of the game and reproducing various sound effects due to the progress of the game.

The display unit (170) includes a beam projector (171) and a screen (172). The beam projector (171) projects the relevant image onto the screen (172) so that the golf course and golf ball are displayed on the screen (172), and the screen (172) displays the projected golf-related image. Provide to users. In the following, some objects displayed on the screen (172) can be expressed with the term "virtual". This means that it does not exist in the real world but is displayed on the screen (172). For example, "virtual golf course" means a golf course displayed on the screen (172), and "virtual golf ball" means a golf ball displayed on the screen (172).

The process of screen golf play in the virtual golf device (100) having the above configuration is as follows. When the user hits a golf ball on the hit plate (110), the sensing unit (140) senses the physical state of the hit golf ball, and the control unit (120) senses information from the sensing unit (140). The flight trajectory of the hit golf ball is calculated based on the above, and the screen (172) displays an image of the virtual golf ball moving as calculated above. At this time, the virtual golf ball on the screen (172) flies to the calculated trajectory and then lands at a specific point on the virtual golf course on the screen (172), and the user uses the virtual golf ball on the screen (172). The above process is repeated until the hole is made into the hole cup while continuing to hit the ball from the point where the ball lands.

According to this embodiment, the virtual golf device (100) identifies a golf ball hit by the user and displays it on a screen. Referring to FIG. 14, the operation of identifying and displaying an actual golf ball involves a plurality of steps. The actual golf ball placed on the hit plate (110) is detected in the first step (S1), the golf ball detected in the second step (S2) is identified, and the golf ball is identified in the third step (S3). A virtual golf ball corresponding to the golf ball is displayed. The specific contents of each of the first to third steps (S1, S2, S3) are as follows.

Referring to FIG. 15, in the first step (S1), the sensor (2) acquires the image (GI) of the golf ball while the hitting golf ball (1) is placed on the hitting plate (110). do. The image of a golf ball (GI) should not always be obtained when the golf ball is placed on the batting plate (110), even if the golf ball is photographed and acquired after it has been hit. good. The golf ball (1) is a personal golf ball prepared separately by the user, or a golf ball provided by a virtual golf device (100). As the detector (2), a camera having a shooting function or the like can be used. The detector (2) can serve as a sensing unit (140) for sensing the physical state of the hit golf ball (1). In other words, the detector (2) serves as a sensing unit (140) that senses the physical state of the golf ball (1), and also photographs the golf ball (1) placed on the hit plate (110). It can play a role in generating the image (GI) of a golf ball. Alternatively, the detector (2) is provided separately from the sensing unit (140) and only has the role of generating a golf ball image (GI) from the golf ball (1) placed on the batting plate (110). Can be fulfilled.

Referring to FIG. 16, in the second step (S2), the golf ball is identified from the golf ball image (GI). As illustrated in FIG. 16, the storage unit (130) stores data for a plurality of golf balls. Specifically, in the storage unit (130), information on each golf ball is separately stored for each golf ball in a storage area for information on the golf ball. For example, information for each golf ball such as golf ball GB1 and golf ball GB2 is classified, and the information of each classified golf ball includes image information, product information, spec information, and the like. The image information is exposed to the outside, such as the overall outline of the golf ball, a picture, characters, symbols, etc. displayed on the surface of the golf ball, such as an uneven pattern on the surface for showing dimples. Includes all external properties for. The product information includes information such as a manufacturer, a manufacturing date (release date), a model name, a size, a weight, and a material. The spec information includes information indicating the characteristics and performance of the golf ball. For example, a golf ball has various specifications such as wind-resistant medium trajectory characteristics, high and / or long flight characteristics, soft shot feeling characteristics, straight flight characteristics, etc., depending on the material, shape, dimple pattern, etc. Can be done.

In order to identify the golf ball, the control unit (120) uses the image of the golf ball (GI) obtained in the first step (S1) and the image information of each golf ball stored in the storage unit (130). While comparing, the process of searching for a golf ball corresponding to the golf ball image (GI) among the stored golf balls is performed. For example, compare the golf ball GB1 image (I1) with the golf ball image (GI) from the first storage. As a result of the comparison, if it is judged that they are different from each other, the image of the golf ball GB2 (I2) and the image of the golf ball (GI) from the second storage are compared. In the comparison process, it is possible to make an overall comparison of the overall contour of the golf ball to be compared, the uneven pattern on the surface such as the picture, characters, and symbols displayed on the surface of the golf ball. By repeating this process, the same image (I2) as the golf ball image (GI) can be found, and as a result, the golf ball corresponding to the golf ball image (GI) is a GB2 golf ball. I understand.

As illustrated in FIGS. 17-20, in the third step (S3), a virtual golf ball corresponding to the identified golf ball is displayed on the screen in various ways. Referring to FIG. 17, the screen displays a window (W) displaying information on the playing user. In the user's window (W), simple information about the user (user ID, personal record, etc.) is displayed. In addition, the user's window (W) displays simplified information (golf ball manufacturer, product name, etc.) indicating the identified golf ball. Referring to FIG. 18, the user's window (W) on the screen displays only the user's brief information (such as user ID and personal records) and is a virtual golf ball (VB) that corresponds to the golf ball used by the user. ) Can be displayed in more detail in the main part of the screen (such as the center or bottom of the screen). At this time, the virtual golf ball (VB) is displayed so as to have an image corresponding to the actual golf ball identified. Since the main use of the screen is to display a virtual golf ball and a virtual golf course, the image of the virtual golf ball (VB) corresponding to the identified real golf ball can be viewed by the user as the actual golf ball. It is preferable to make it disappear after being displayed only in the state before hitting. Referring to FIG. 19, the virtual golf ball (VB) moves along a locus (T) calculated based on the physical state of the actual golf ball hit by the control unit (120). The virtual golf ball (VB) moving along the trajectory (T) is displayed to have an image corresponding to the actual golf ball identified in the second step (S2). Referring to FIG. 20, the virtual golf ball moves along the trajectory (T) calculated by the control unit (120) (named “first virtual golf ball (VB)” for convenience). Includes two that are displayed as an enlarged image in a separate window (W') (named "Second Virtual Golf Ball (VB')" for convenience). Here, at least the second virtual golf ball (VB') of the first and second virtual golf balls (VB, VB') has an image corresponding to the actual golf ball identified. Displayed to have. The first virtual golf ball (VB) occupies a very small area compared to the overall screen size, so even if it appears to have an image that corresponds to the actual golf ball identified, the user However, it is not easy to grasp with the naked eye. In comparison, the second virtual golf ball (VB') displayed in another window (W') can be displayed as a magnified image to provide additional information. Since it is an enlarged image, the user can easily grasp it with the naked eye if he / she has an image corresponding to the actual golf ball. Here, the second virtual golf ball (VB') can provide the spin direction of the golf ball hit by the user as the additional information. A second virtual golf ball (VB') can also be used to provide additional information useful to the user's play, not just the spin direction.

As mentioned above, if the virtual golf ball (VB) has an image corresponding to the actual golf ball, the user can easily understand what kind of golf ball he / she is using. Can be done. In particular, when a user plays with his or her personal golf ball (first play mode), the screen displays a real image of his or her personal golf ball, so that the user can play his or her own golf course outdoors. You can experience the feeling of playing with an individual golf ball, which can greatly improve the reality of screen golf.

In order to further improve the reality of screen golf, the virtual golf ball (VB) not only has an image corresponding to the actual golf ball, but also the virtual golf ball (VB) is deformed during the play of screen golf. When a situation occurs, it is possible to have an image that reflects such a deformation situation. For example, when the virtual golf ball (VB) moves along the trajectory (T) calculated by the control unit (120) and the surface is scratched (the virtual golf ball (VB) becomes a hard object). The virtual golf ball (VB) after that (for example, when the surface is scratched due to collision or scratching) can be displayed with the scratch image added to the image corresponding to the real thing. As a result, the user feels as if the golf ball is damaged in the actual golf play, and the reality of screen golf can be greatly improved.

Referring to FIG. 21, the virtual golf device (100) can use an interface device (111) for selecting the first and second play modes. The interface device (111) is located in the vicinity of the batting plate (110), and a user located in the batting plate (110) to hit a golf ball can use the nearby interface device (111). You can easily select either the first or second play mode at any time. The interface device (111) has a "1st button (111a)" for selecting the first play mode and a "2nd button (111b)" for selecting the second play mode. Can easily select either the first or second play mode by stepping on either the first button (111a) or the second button (111b). For example, a user may press button 1 (111a) or button 2 (111b) to select a first or second play mode before making the first hit (tee shot) in a round of a particular golf course. can do. In addition, when the user makes an intermediate hit after the tee shot (for example, when the hit golf ball falls into the orbi area and receives a penalty and hits again), the user takes the first or second hit before the hit. By stepping on the number buttons (111a, 111b) with your foot, you can change the play mode as you wish even in the middle of the course capture.

The interface device (111) has not only a button for selecting the first and second play modes, but also other buttons (111c) for entering commands that the user frequently uses while playing screen golf. There can be. For example, the button (111c) can serve to adjust the angle and position at which the screen is displayed.

The interface device (111) is not mandatory and the user may select one of the first and second play modes using a normal input device such as a mouse or keyboard. can.

Identify the golf ball. Since the contents of the steps (S1, S2) described with reference to FIGS. 15 and 16 can be applied to the second and third steps (S20, S30), detailed description thereof will be omitted.

In the fourth step (S40), the control unit (220) checks whether the identified golf ball (the golf ball used by the user at the time of hitting) and the golf ball selected in the selection process are the same, and as a result, they are the same. In the case of, the golf ball trajectory is calculated by the first calculation method in the fifth step (S50), and if they are not the same, the golf ball trajectory is calculated by the second calculation method in the sixth step (S60). calculate. After the selection process, the user can actually hit the same golf ball as the golf ball of his choice, or hit a golf ball different from the golf ball of his choice, and the golf of choice. When the same golf ball as the ball is hit, the fifth step (S50) is performed, and when a golf ball different from the selected golf ball is hit, the sixth step (S60) is performed.

Referring to FIG. 25, in the calculation process by the first calculation method, the trajectory of the golf ball (B) is calculated based on the physical state of the golf ball (B) hit by the user. do. The physical state of the golf ball (B) is sensed by the sensing unit (240). The physical state can be grasped by various physical parameter values. The above-mentioned physical parameters are very diverse in type, and the movement of the actual golf ball (B) hit is also fluctuated with time and time, so when calculating the trajectory in consideration of all of these. The calculation process becomes very complicated. Therefore, for convenience of explanation, the trajectory of the golf ball (B) is calculated using a simple model using only a part of various physical parameters of the golf ball (B) (for example, the moving speed and the moving direction of the golf ball). Explain the process.

As illustrated in FIG. 25, when the user hits the golf ball (B), the golf ball (B) flies at a predetermined speed (V1) and direction (θ1). Here, the velocity (V1) is the initial velocity immediately after the golf ball (B) is hit, and the direction (θ1) is an angle inclined with respect to the horizontal plane as a factor indicating the direction of flight by the hit. In the calculation process, it is calculated what kind of trajectory (T1) the golf ball (B) has when it moves with the physical parameters (V1, θ1). After extracting the parameters indicating the physical properties of the golf ball (B) in this way, the first calculation method is to calculate the locus (T1) by using the parameters as they are. In short, the actual golf ball (B) hit by the user is used as it is without changing the physical state. Since the first calculation method hits the same golf ball as the golf ball selected by the user, the "user's selection condition" and the "actual hitting condition" correspond to each other, and the calculation process in the first calculation method. Follows the usual calculation method as it is when both conditions correspond.

On the other hand, in the second calculation method, a golf ball different from the golf ball selected by the user is hit, and the "user's selection condition" and the "actual hitting condition" do not correspond to each other. The second calculation method applies a method different from the normal calculation method in order to compensate for the discrepancy between the two conditions. For example, the trajectory of the golf ball is calculated by partially or wholly changing the parameter indicating the physical properties of the golf ball (B) grasped from the sensing unit (240) in the calculation process. Specifically, referring to (a) of FIG. 26, it is assumed that the golf ball (B) hit by the user has a predetermined velocity (V1) and direction (θ1). Assuming that the first locus (T1) is calculated from the physical parameters (V1, θ1), in this method, the velocity value of the physical parameter of the golf ball is deformed to obtain the deformation value “V2” as follows. To calculate.
V2 = f (V1, α)
In this way, when the deformation value "V2" is calculated from the first velocity value (V1), the locus (T2) is calculated from the deformed velocity (V2) and the direction value (θ1).
α is a variable indicating the difference between the specifications of the golf ball selected by the user and the specifications of the golf ball actually used (α = Δ (specs of the selected golf ball-specs of the golf ball used)). f (V1, α) is a function or mathematical formula with V1 and α as variables. For example, if there is a difference in flight distance characteristics between the selected golf ball and the used golf ball, and a speed difference of only α is uniformly generated for the same swing, f (V1, α). ) Is in a simple form
f (V1, α) = V1 + α
become. According to such a form, the velocity V1 of the hit golf ball (B) increases or decreases according to the value of α, V1 is changed to V2, and the calculation process based on the changed V2 The trajectory of the golf ball changes. When the user selects golf ball A and actually hits with golf ball B, V1 and θ1 show the hit result by golf ball B, but when the calculation process is performed using only V1 and θ1. The act of the user selecting golf ball A cannot be reflected in the calculation process. However, after deriving a function or formula such as f (V1, α) in consideration of the specifications of the golf ball A, and thereby changing the speed value from V1 to V2, the calculation is based on V2, θ1. When performing the process, the result of the action of the user selecting the golf ball A can be reflected in the trajectory of the golf ball hit by the user.

For example, the golf ball A selected by the user is a golf ball that the user personally owns, and the golf ball B actually hit by the user is a golf ball provided at a screen golf course where a virtual golf device is installed. Suppose that Since the user hits his own golf ball A at the actual golf course, there is a high possibility that he / she wants to hit his / her own golf ball A when hitting the golf ball at the screen golf course. However, it may be necessary to hit a golf ball different from the personal golf ball A, such as when the user does not bring his personal golf ball A to the screen golf course. In such a case, the user has no choice but to use the golf ball provided in the screen golf course, but he / she knows the hit result when hitting his / her own golf ball. In consideration of these points, in the virtual golf device according to the embodiment of the present invention, a second calculation method for calculating the trajectory of a golf ball in a state assuming that the golf ball selected by oneself is hit is applied. .. As a result, when the golf ball A selected by the user and the golf ball B actually hit by the user are considered, the case of hitting the golf ball A is the case of hitting the golf ball B. When it is judged that the speed of the hit golf ball increases by a predetermined fluctuation (α),
f (V1, α) = V1 + α
The velocity value (V2) transformed from the actual velocity value (V1) is derived from the actual velocity value (V1), and the trajectory of the golf ball is calculated based on this.

Due to the difference in specifications between the golf ball A selected here and the golf ball B used, f (V1, α) is not a simple form to add a predetermined variation (α), but a more complicated form. There is also the possibility of becoming. Since the spec difference between golf balls is very diverse, it is possible that the formula is not just a formula as described above, but a more complicated formula. You can create and apply complex formulas.
Not only the velocity can be changed, but other variables can be changed to calculate the trajectory of the golf ball. For example, as shown in FIG. 26 (b), it is assumed that the golf ball (B) hit by the user has a predetermined velocity (V1) and direction (θ1). Assuming that the first locus (T1) is calculated from the physical parameters (V1, θ1), the deformation value “θ2” is calculated by transforming the direction value of the physical parameter of the golf ball as follows. ..
θ2 = f (θ1, α)
As described above, when the deformation value "θ2" is calculated from the first direction value (θ1), the locus (T2) is calculated from the velocity (V1) and the deformation value (θ2).
f (θ1, α) is a function or mathematical formula with θ1 and α as variables. f (θ1, α) is in a simple form
f (θ1, α) = θ1 + α
become.

Since the spec difference between golf balls is very diverse, it is possible that the formula is not just a formula as described above, but a more complicated formula. You can create and apply complex formulas.

In this way, the parameters indicating the physical properties of the golf ball (B) are extracted, and at least some of the parameters are artificially set based on the spec difference between the golf ball selected by the user and the golf ball hit by the user. The calculation process by the second calculation method is to calculate the locus (T2) based on this after the transformation to. Here, only two physical parameters, a speed value and a direction value, are explained as an example, but this is only a brief explanation for the sake of understanding, and there are various ways to calculate the trajectory of a golf ball. Since physical parameters (golf ball spin direction, spin value, etc.) can be used, it is also possible to calculate the changed golf ball trajectory by changing other physical parameters other than the speed value and the direction value. ..

Referring to FIG. 27, when there are a plurality of users playing screen golf, it is possible that the first calculation method is applied to which user and the second calculation method is applied to which user. For example, User A and User B play together, User A has the same golf ball selected in the selection process and the golf ball used for hitting, and User B uses the golf ball selected in the selection process and hits. It is assumed that the golf ball is different from the golf ball. As a result, the first output method is applied to user A, and the second output method is applied to user B. As illustrated in FIG. 27, when User A plays, User A's window (W1) is displayed on the screen, and when User B plays, User B's window (W2) is displayed on the screen. In the user window (W1, W2), personal information (ID, name, nickname, etc.) that can identify the user, past records of the user, current play status, etc. are easily displayed. In addition, the user's window (W1, W2) displays what calculation method is applied to the user, and the user can refer to his / her window to check the calculation method applied to himself / herself. .. Users can change the currently applied calculation method while changing the golf ball selection or the golf ball they are using, so that they can enjoy screen golf the way they like. ..

The operation process in which the first or second calculation method is applied and the calculated trajectory of the golf ball changes depending on whether the golf ball is selected and the same golf ball as the selected golf ball is hit will be described above. did. During the selection process, the user can select his or her own golf ball and experience the feeling of hitting with his or her personal items on a clean golf course, resulting in a screen. The reality of golf can be improved. Alternatively, the user can select an unknown golf ball that he / she has never actually used, and in this case, the user can experience the hit feeling of the unknown golf ball in advance.
