Description

A virtual golf device providing golf club information and a virtual golf system using the same

The present invention relates to a virtual golf device and a virtual golf system using the same, and more particularly, provides information about a golf club used for hitting a golf ball in virtual golf play such as screen golf, and also provides a user's own personal golf club. The present invention relates to a virtual golf device for providing usable golf club information and a virtual golf system using the same.

Simulation devices for enjoying sports games without going out to the field have been developed using 3D stereoscopic images and computer simulation technology, and virtual indoor sports games such as golf and baseball are widely distributed. In the case of screen golf, which is a representative indoor sport, the image of the golf course is displayed through the screen, giving the feeling of being playing an actual golf game outdoors, while saving time and money compared to playing in an outdoor field. It is very popular among modern people who find it difficult to play golf due to time or financial reasons.

An important point in the popularization of screen golf is whether real golf can be realistically reproduced. Screen golf reflects and plays various things applied to real golf in order to realistically reproduce real golf. For example, in an actual golf course, terrain having various properties such as fairways, roughs, and bunkers exists, and various terrains such as fairways, roughs, and bunkers are displayed on the golf course on the screen. In addition, in screen golf, a plurality of areas such as a fairway correspondence area, a rough correspondence area, and a bunker correspondence area are divided in the hitting plate on which the golf ball is placed in screen golf. By placing a golf ball on the rough-corresponding area on the plate and hitting it, it is possible to experience the feeling of hitting like hitting a golf ball that landed on the rough in real golf.

It is a view showing an example of a screen displayed on the screen after a user selects a golf club in the virtual golf device of

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

The striking plate 10 is a place for striking a golf ball, and the user strikes the golf ball placed therein by being positioned on the striking plate 10 .

The control unit 20 serves to control the overall operation between the components of the virtual golf device. For example, although not shown in the drawings, an auto tee that automatically provides a hitting golf ball may be installed in the striking plate 10, and the control unit 20 controls the auto tee in accordance with the timing of the user hitting. You can control the golf ball to be provided. In addition, the control unit 20 performs a calculation process for calculating the trajectory of the golf ball. In the calculation process, when the user hits the golf ball, assuming that the golf ball actually flies on the golf course, what kind of trajectory and/or how far the golf ball will fly is calculated.

The storage unit 30 may store various data necessary for the operation of the virtual golf device, and also stores information on various golf clubs. The golf club includes commercial golf clubs currently used in the market.

The sensing unit 40 detects a physical state such as a speed, a movement direction, a rotation angle, etc. of a golf ball hit by a user. The sensing unit 40 includes a sensing unit for detecting the physical state of the golf ball, and various sensing sensors or cameras may be used as the sensing unit. The camera or the detection sensor may be used alone or together, and may be used singularly or used in plurality. The information sensed by the detector 40 is transmitted to the controller 20 , and the controller 20 performs a calculation process based on the information sensed by the detector 40 .

The input unit 50 is for receiving various types of information from the user, and a keyboard/mouse or a touch screen may be used. In screen golf, information input from the user is sometimes required, such as when the user inputs his or her ID or password to log in, or when the user selects a golf course or difficulty to play. (50) is provided. Information input from the input unit 50 is transmitted to the control unit 20, and the control unit 20 processes a user's request based on the transmitted information. For example, when the user selects a specific golf course, the control unit 20 performs necessary processing so that the user can play on the golf course. When a golf course is selected, the image processing means may transmit the golf course image to the display unit 70 to be displayed. In addition, when the user inputs personal information such as a child or password for login, the control unit 20 may check the input personal information to determine whether to approve the login.

The sound unit 60 includes a sound device such as a speaker, and serves to guide the user to the progress of the game and to reproduce various sound effects according to the progress of the game.

The display unit 70 may include a beam projector 71 and a screen 72 . The beam projector 71 projects a related image to the screen 72 so that the golf course and golf ball are displayed on the screen 72, and the screen 72 serves to display the projected golf related image to the user. For reference, hereinafter, some objects displayed on the screen 72 may be expressed by attaching the term 'virtual'. This means that it does not exist in the real world and is displayed on the screen 72 . For example, 'virtual golf course' means a golf course displayed on the screen 72, and 'virtual golf ball' is a screen It means that it is a golf ball displayed in (72).

The screen golf play process in the virtual golf device having the above configuration is as follows. When the user hits the golf ball on the striking plate 10, the control unit 20 calculates the flight trajectory of the hit golf ball based on the sensing information from the sensing unit 40, and on the screen 72, the calculated As a result, an image of a virtual golf ball moving is displayed. At this time, the virtual golf ball in the screen 72 flies on the calculated trajectory and then lands at a specific point on the virtual golf course in the screen 72 , and the user sees the virtual golf ball in the screen 72 . Repeat the above process until you hit a hole in the hole cup while continuing to hit from the spot.

Referring to FIG. 2 , before hitting an actual golf ball, a user may perform a selection process for a golf club, and the golf club information stored in the storage unit 30 is displayed on the screen 72 during the selection process. do. The golf clubs may be classified and displayed according to functions such as drivers, woods, irons, hybrids, wedges, and putters. Commercial golf clubs currently circulating in the market may be displayed in each club item divided by function as described above. Accordingly, when a driver shot is required, the user can select a desired driver's golf club from the driver club item. In addition, when an iron shot is required, the user can select a desired iron golf club from the iron club item, and when other shots are required, the user can select a desired golf club from the club of the corresponding item.

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 shown in Fig. 3 (a), the screen 72 displays a window W displaying the information of the user who is playing, and there is brief information about the user (ID or personal record, etc.) may be displayed. The user window W may also display which golf club the user has selected. The user can play while checking the golf club selected by the user by referring to the window (W). Alternatively, as shown in Fig. 3(b), only brief information about the user (such as an ID or personal record) is displayed in the window W of the user in the screen 72, and the golf club GC selected by the user is displayed on the screen. It can be displayed in more detail on the main part (such as the center or the bottom of the screen 72) of (72). However, since the main purpose of the screen 72 is to show a virtual golf ball and a virtual golf course, the selected golf club (GC) image is displayed on the main part of the screen 72 so as not to interfere with showing the virtual golf course, etc. It is desirable to make the golf club (GC) disappear after being shown only for a certain period of time.

For the selection process, information on various golf clubs is stored in the storage unit 30 . Also, the storage unit 30 may store user information for each user. Referring to FIG. 4 , the storage unit 30 may include a storage area I1 for golf club information and a storage area I2 for user information. In the storage area (I1) of the golf club information, information (I11, I12, ...) for each golf club is stored separately for each golf club. Information (I11, I12, ...) for each golf club includes image information, product information, specification information, and the like. The image information includes an image of an entire golf club or an image of a major part of a golf club such as a head or a shaft. The product information includes information such as manufacturer, manufacturing year (release year), model name, size, weight, material, and the like. The specification information includes information such as a loft angle, lie angle, shaft strength, shaft torque, and the like (the specification information value of the golf club may be referred to as a 'club variable' in this 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 gender, age, height, weight, and history of the user. The play record information includes an average number of strokes, an average distance, and an average speed of a hit ball as a cumulative record that the user has played on the screen golf course. The golf club information includes information such as a golf club selected by the user in the selection process, and a golf club personally used by the user.

5 is a schematic configuration diagram of a virtual golf apparatus 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 is provided. A computer device capable of driving a predetermined software may be used as the control unit 20 , an input device such as a keyboard or mouse may be used as the input unit 30 , and a camera may be used as the sensing unit 40 . These configurations are not significantly different from those in the embodiment described with reference to FIG. 1 , and detailed description thereof will be omitted. Although not shown in the drawings, the storage unit in the embodiment described with reference to FIG. 1 may be provided in the storage device inside the control unit 20, and the sound unit may be provided in the form of a separately provided speaker. Compared with the embodiment described with reference to FIG. 1 , the virtual golf apparatus according to the present embodiment further includes an auxiliary display 80 . A monitor or a kiosk may be used as the auxiliary display 80 . Various types of information may be displayed on the auxiliary display 80 for user convenience. For example, golf club information (refer to FIG. 2 ) for performing a selection process for selecting a golf club may be displayed on the auxiliary display 80 . Both the screen 72 and the auxiliary display 80 can show various types of information or images to the user, but the screen 72 mainly shows images related to screen golf, and the auxiliary display 80 provides auxiliary information necessary for the user. They can be displayed so that they can perform different roles. As described above, according to the present embodiment, the screen 72 showing the main image in screen golf and the auxiliary display 80 showing the auxiliary information necessary for the user are separately provided according to the type of object to be displayed, so that the user's It has the effect of improving convenience.

In the case of performing the selection process, the user may actually hit a golf ball with a golf club selected by the user or may hit a golf ball with a golf club different from the golf club selected by the user. According to whether a golf ball is hit with the same golf club as the selected golf club, the virtual golf apparatus of the present invention provides various play modes so that the user can play in various ways. Specifically, there is provided a first play mode in which hitting with the same golf club as the selected golf club and a second play mode in which hitting with a golf club different from the selected golf club are provided. There may be differences in the calculation process. Hereinafter, the first and second play modes will be described.

6 is a view 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 apparatus according to an embodiment of the present invention, and FIG. 7 is an embodiment of the present invention. It is a view 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 present invention, and FIG. 8 is a screen displayed on the screen when the first and second play modes are applied 9 is a diagram showing an example of an interface device that allows a user to select a play mode when the first and second play modes are applied, and FIG. 10 is a modification of the first and second play modes It is a diagram showing an example of a screen screen according to an example.

Referring to FIG. 6 , in the calculation process in the first play mode, it is calculated which trajectory the golf ball B will fly based on the physical state of the golf ball B hit by the user. The physical state of the golf ball (B) is detected by the sensing unit 40, the physical state may be grasped by various physical parameter values. Since the physical parameters are very diverse and the movement of the hit actual golf ball B is also changed every moment, when calculating the trajectory in consideration of all of them, the calculation process becomes very complicated. Therefore, for convenience of explanation, a process of calculating the trajectory of the golf ball B will be described with a very simplified model using only some of the various physical parameters for the golf ball B (eg, the moving speed and the moving direction of the golf ball).

As shown in FIG. 6 , when the user strikes the golf ball B, the golf ball B flies with a predetermined speed V1 and a direction θ1. Here, the velocity V1 may be the initial velocity immediately after the golf ball is hit, and the direction θ1 may be an angle inclined with respect to the horizontal plane as a factor indicating the direction in which the golf ball flies by the strike. In the calculation process, it is calculated what trajectory T1 the golf ball B will have when it moves with the physical parameters V1 and θ1. In this way, after extracting the parameters indicating the physical properties of the golf ball B, calculating the trajectory T1 using the parameters as they are is a calculation process under the first play mode. In other words, it is used without changing the physical state of the actual golf ball (B) hit by the user, and this is a typical calculation method. The first play mode is to hit a golf ball 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 the calculation process in the first play mode is positive If the conditions match, the usual calculation method is followed.

In contrast, in the second play mode, a golf ball is hit with a golf club different from the golf club selected by the user, so that the 'user's selection condition' and the 'actual hitting condition' are different from each other, and the calculation in the second play mode In order to compensate for the discrepancy between the two conditions, the process applies a method different from the usual calculation method. For example, the trajectory of the golf ball may be calculated by partially changing parameters indicating the physical properties of the golf ball B identified by the sensing unit 40 in the calculation process. Specifically, referring to FIG. 7( a ), when it is assumed that the golf ball B hit by the user has a predetermined speed V1 and a direction θ1 , the first from the above physical parameters V1 and θ1 Assuming that 1 trajectory T1 is calculated, in this method, the velocity value among the physical parameters of the golf ball is transformed to calculate the deformation value 'V2' as follows.

V2 = f(V1, α)

As described above, when the deformation value 'V2' is calculated from the initial velocity value V1, the trajectory T2 is calculated from the deformed velocity V2 and the direction value θ1.

Here, α is a variable representing the difference value of the club variable according to the difference between the specification of the golf club selected by the user and the specification of the golf club actually used (α = Δ (selected golf club - used golf club)), f(V1, α) can be said to be a function or expression using V1 and α as variables. For example, if there is a difference in shot strength between the selected golf club and the used golf club, so that a speed difference of α occurs uniformly for the same swing, f(V1, α) is a simple form

f(V1, α) = V1 + α

can be According to this form, the velocity V1 of the hit golf ball (B) increases or decreases according to the value of α and is transformed into V2, and the trajectory of the golf ball is changed in the calculation process based on the deformed V2. When the user selects golf club A and actually hits using golf club B, V1 and θ1 represent hitting results by golf club B, but if the calculation process is performed using only V1 and θ1, the user The act of selecting A cannot be reflected in the calculation process. However, if a function or formula such as f(V1, α) is derived in consideration of the club variable of golf club A, the speed value is transformed from V1 to V2 accordingly, and the calculation process is performed based on V2, θ1. A result of the act of selecting golf club A may be reflected in the trajectory of the golf ball hit by the user.

For example, it is assumed that the golf club A selected by the user is a golf club personally owned by the user, and the golf club B used when the user actually hits is a golf club provided in a screen golf course in which a virtual golf device is installed. Since the user hits a golf ball using his or her own golf club A on an actual golf course, even when hitting a golf ball on a screen golf course, the user may wish to hit using his or her golf club A. It is possible to bring and use one's own golf club when playing at the screen golf course, but since it is not always easy to visit the screen golf course with one's own personal equipment, it is not easy to visit the screen golf course. You can also use clubs. In this case, the user may wonder what the hitting result will be when he uses the golf club provided in the screen golf course in an unavoidable situation, but hits using his or her own golf club. In consideration of this point, the virtual golf apparatus according to an embodiment of the present invention provides a second play mode for calculating the trajectory of a golf ball under the assumption that a golf club selected by the user is used. Accordingly, when considering the various specifications of the golf club A selected by the user and the golf club B actually used by the user, the speed of the hit golf ball is predetermined when golf club A is used compared to when golf club B is used. If it is determined that it increases by the variation (α) of Calculate the trajectory.

Here, depending on the difference in specifications between the golf club A selected and the golf club B used, f(V1, α) may have a more complex form rather than a simple form of adding a predetermined variation α. Because the difference in specifications between golf clubs is very diverse, it can be a more complicated formula rather than a simple formula like the one above.

The trajectory of the golf ball can be calculated by changing other variables without changing the velocity value. For example, as shown in FIG. 7(b), when it is assumed that the golf ball B hit by the user has a predetermined speed V1 and a direction θ1, the physical parameters V1 and θ1 ), assuming that the first trajectory T1 is calculated from the directional value, not the velocity value, among the physical parameters of the golf ball, the deformation value 'θ2' can be calculated as follows.

θ2 = f(θ1, α)

As above, when the deformation value 'θ2' is calculated from the initial direction value θ1, the trajectory T2 is calculated from the velocity V1 and the deformation value θ2.

Here, 'f(θ1, α)' is a function or formula using θ1 and α as variables.

f(θ1, α) = θ1 + α

can be However, since the difference in specifications between golf clubs is very diverse, it can be a more complicated calculation formula rather than a simple calculation formula as above.

In this way, parameters representing the physical properties of the golf ball B are extracted, and at least some of the parameters are artificially transformed according to the difference in specifications between the golf club selected by the user and the golf club hit by the user, and then based on this Calculating the raw trajectory T2 is a calculation process applied to the second play mode. Here, only two physical parameters, a speed value and a direction, have been described as examples, but this is only a simplified description to help understanding, and there are various physical parameters (spin direction of the golf ball, spin value, etc.) in calculating the trajectory of the golf ball. ) can be used, so it is also possible to calculate the trajectory of a deformed golf ball by modifying various other physical parameters other than the velocity value and direction.

Referring to FIG. 8 , when a plurality of users play screen golf, each user may select and play one of the first play mode and the second play mode before starting to play. For example, it is assumed that user A and user B play together, but 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, as shown in FIG. 8, when user A plays, a window W1 for user A is displayed on the screen 72, and the user When B plays, a window W2 for user B may be displayed on the screen 72 . In the user windows W1 and W2, personal information that can identify the user (ID, name, nickname, etc.) and the user's past record or current play status may be briefly displayed. In addition, the user windows W1 and W2 may also display in which play mode the user is playing, and the user may refer to the user's window and confirm under which mode the user is playing. Accordingly, the user can enjoy screen golf in a desired manner while playing while maintaining the set mode as it is, or changing the set mode using various input means and playing the current batting process.

Referring to FIG. 9 , a separate input means 11 for selecting the first and second play modes may be provided in the virtual golf apparatus. The input means 11 is disposed in the vicinity of the striking plate 10, so that the user located on the striking plate 10 to hit the golf ball can conveniently use the first and second input means 11 at any time by using the input means 11 located in the vicinity. You can choose any one of 2 play modes. For example, the input means 11 may be provided with 'No. ① button 11a' for selecting the first play mode and 'No. ② button 11b' for selecting the second play mode, The user can easily select a desired mode among the first and second play modes by stepping on any one of the ① button 11a and the ② button 11b with a foot. The input means 11 may further include a button for selecting the first and second play modes, as well as another button 11c for inputting a command frequently used by the user during screen golf play. For example, the button 11c may be a button for adjusting an angle or position at which a picture in a screen is viewed.

The input means 11 is not essential, and the user may select a desired play mode among the first and second play modes using a general input device such as a mouse or keyboard. Also, when there is no user's selection, the virtual golf apparatus may automatically select any one of the first and second play modes. For example, if the user skips the selection process and does not specifically select a golf club, it is assumed that the same golf club as that provided in the screen golf course is selected, and the first play mode may be automatically selected. Or a golf club detection means such as a camera is provided to automatically and/or manually detect a golf club used when a user hits a golf ball, and whether the golf club selected by the user is the same as the golf club detected by the detection means After checking, any one of the first and second play modes may be automatically selected according to the check result.

Select the above golf club, play in the first or second play mode depending on whether hitting with the same golf club as the selected golf club, and the trajectory of the golf ball calculated in the calculation process varies according to the first and second play modes The method has been described. In particular, when the user selects a golf club that he personally owns under the second play mode, the user can feel the hitting feeling as if hitting using his or her own personal equipment on the screen golf course, and Accordingly, the reality of screen golf can be improved. Alternatively, in the second play mode, the user can select an unknown golf club that he has never actually used. In this case, the user can experience the feeling of hitting the unknown golf club in advance.

In addition to the first and second play modes, a play method modified therefrom is also possible. For example, when the golf club selected by the user and the golf club used by the user are different from each other, the first trajectory is calculated in the calculation process (calculating the trajectory without changing the physical parameters of the golf ball) in the first play mode method, , it is assumed that the second trajectory is calculated in the calculation process (calculating the trajectory by changing the physical parameters of the golf ball) in the second play mode method. Referring to FIG. 10A , both the first trajectory T10 and the second trajectory T20 may be displayed on the screen 72 (or the auxiliary display 80 of FIG. 5 ). As a result, the user can directly compare the hitting result according to the golf club used for the actual hitting with the hitting result according to the golf club selected by the user. Alternatively, the user may select a plurality of golf clubs in the selection process. For example, in the selection process, the user selects a first golf club that is his or her personal equipment and a second golf club that he does not have, and the actual hitting is performed at the screen golf course. Assuming that the first and second golf clubs are hit with different golf clubs, the calculation process in the first play mode method (first trajectory) and the calculation process in the second play mode method for the first and second golf clubs (second play mode) 2 and 3), the first trajectory T10, the second trajectory T21, and the third trajectory T22 may be displayed together as shown in FIG. 10(b) . As a result, the user can directly compare the difference between the hitting result by the currently used golf club (T10), the hitting result by the golf club he owns (T21), and the hitting result by the golf club he does not have (T22). And you can figure out which golf club is more suitable for you. In particular, when the user does not like the golf club he currently owns and intends to purchase a new golf club, he selects and hits various golf clubs as the second golf club, compares the results, and compares the results. You can decide for yourself which golf club to purchase based on the basis.

11 is a view showing an example of a screen screen that provides information about a seller while recommending a golf club to a user.

While comparing the hitting results after selecting various golf clubs above, it has been said that the user can determine which golf club is suitable for the user by himself or herself, which can also be performed by the control unit 20 . That is, by applying the calculation process under the second play mode when the user hits, the hitting result when using various golf clubs can be calculated, and the control unit 20 finds a golf club suitable for the user and compares these calculation results. can recommend In addition, the control unit 20 may utilize information stored in the storage unit 30 to recommend a golf club. As described with reference to FIG. 4 , user information (personal information, play record information, etc.) and golf club information (spec information, etc.) are stored in the storage unit 30, and a golf club suitable for the user is recommended by using this can do. In the recommendation step, a single golf club may be recommended or a plurality of golf clubs may be recommended. In the case of recommending a plurality of golf clubs, if each golf club has a different degree of suitability to the user, this may be displayed as a numerical value. For example, if the degree of fitness for the user of company A's golf club XXX is 95 and the degree of fitness for the user of company B's golf club is 90, as shown in FIG. . In addition, it is possible to provide convenience so that the recommended user can purchase a favorite golf club immediately by not only recommending the golf club but also providing information on the seller of the recommended golf club. When there are a plurality of vendors and prices are different, information may be provided so that the plurality of vendors and prices of the respective vendors can be compared with each other. The golf club recommendation and vendor information may be displayed on the screen 72, an auxiliary display, or the like.
