1 is a view showing a schematic structure of a virtual golf apparatus according to a first embodiment of the present invention.

Referring to FIG. 1 , the virtual golf device 100 includes a hitting area 110 , an intermediate area 120 , a detector 130 , a controller 140 , beam projectors 150 and 170 , and screens 160 and 180 . In particular, the virtual golf device 100 according to the present embodiment is provided with a golf ball trapping unit 190 .

The hitting area 110 is an area where the user hits the golf ball, and the hitting plate 111 on which the hitting golf ball is placed is disposed. The intermediate region 120 refers to the region between the striking region 110 and the screen 160 , and corresponds to the region where the golf ball hit by the user passes until it reaches the screen 160 .

The sensor 130 detects the movement of the golf ball hit by the user, and detects the overall state information about the hit golf ball, and detects the movement of the golf ball as well as a camera capable of photographing the movement of the golf ball. If possible, any detection means such as a detection sensor may be used. Various sensing methods such as image sensing, light emission/reception sensing, and laser sensing may be applied by the above sensing means, and state information of a golf ball hit by a user may be grasped through this sensing method. The camera, the detection sensor, etc. may be used alone or may be used together, and also only one may be used, or several may be used as needed.

The controller 140 controls the overall operation of the virtual golf device 100 , and the controller 140 is provided with means for calculating the movement of the golf ball hit by the user. The calculation process may be executed by a program installed in the controller 140 , and the calculation means including the program is hereinafter referred to as a 'calculation unit'. Specifically, when a user hits a golf ball, the calculator receives physical state information about the hit golf ball from the sensor 130, and based on it, simulates and calculates a trajectory indicating the movement of the golf ball.

The beam projectors 150 and 170 and the screens 160 and 180 serve to display and show golf-related images. In this embodiment, the screens 160 and 180 include a front screen 160 and a floor screen 180, and the beam projectors 150 and 170 are a front screen beam projector 150 and a floor screen beam projector ( 170). The front screen beam projector 150 projects a golf-related image and provides it to the front screen 160, and the front screen 160 displays the projected image and shows it to the user. Also, the beam projector 170 for the floor screen projects a golf-related image and provides it to the floor screen 180, and the floor screen 180 displays the projected image to show the user. Although the beam projector 150 for the front screen and the beam projector 170 for the bottom screen are provided separately in this embodiment, it is also possible to project an image on a plurality of screens by a single beam projector.

The golf-related image displayed on the screens 160 and 180 includes an image of a golf ball and a background image showing a golf course being played by the user. For reference, in relation to the golf ball mentioned in this specification, in order not to confuse a real golf ball (Real Ball) that a user actually strikes by placing it on the striking plate (111) and a virtual golf ball (Virtual Ball) displayed in the image. , the golf ball in the image may be called a 'virtual golf ball'. Like 'virtual golf ball', the modifier 'virtual' can be attached to some objects to indicate that they are objects in the video. For example, a 'virtual golf course' does not represent a golf course of an actual golf course, but means that the golf course of the golf course is displayed as an image on the screen.

The virtual golf system 100 is a device installed in a screen golf course so that a user can play screen golf, and a schematic operation process of the virtual golf system 100 in screen golf play is as follows.

When the user hits the golf ball, the sensor 130 detects a physical state such as the speed or the moving direction of the golf ball hit by the user. The sensing information sensed by the sensing unit 130 is transmitted to the controller 140, and the calculation unit of the controller 140, based on the transmitted information, assumes that the user hits the golf ball at an actual outdoor golf course. Calculate what trajectory to represent. As a result of the calculation, an image of a virtual golf ball moving is generated, and the image is provided to the user by the beam projectors 150 and 170 and the screens 160 and 180 .

The virtual golf apparatus 100 according to the present embodiment is provided with a golf ball trapping unit 190 . The golf ball capturing unit 190 may be disposed between the striking area 110 and the intermediate area 120 , and in this case, the golf ball capturing unit 190 is the middle of the golf ball hit by the user in the striking area 110 . Block entry into area 120 . In this embodiment, the role of the golf ball trapping unit 190 is related to the operation of the floor screen (180). The floor screen 180 displays a background screen and a virtual golf ball similarly to the front screen 160, and in particular, the floor screen 180 is installed on the floor to realistically show an image of a virtual golf ball rolling on the floor. suitable for When a virtual golf ball rolling on the floor is displayed on the floor screen 180, the virtual golf ball mainly represents an actual golf ball putt by the user. Because, in a blow other than putting, a blow is made to float the golf ball in order to send the golf ball away, so the actual golf ball hit in this way flies in the middle area 120 rather than rolling down the floor in the middle area 120 to the front screen. (160) will collide. On the other hand, when the user puts, the user hits the golf ball while sailing through the hole cup to put the golf ball in the hole cup, so that the actual golf ball hit in this way rolls on the floor in the intermediate region 120 . do. Therefore, the virtual golf ball on the floor screen 180 is suitable to represent the actual golf ball putt by the user rolling on the floor. However, when the virtual golf ball is displayed on the floor screen 180, if the real golf ball put by the user rolls over the floor screen 180 with it, the virtual golf ball and the floor screen 180 in the floor screen 180 image. Since the actual golf ball rolling over is actually a double expression of one golf ball, it can be very unnatural and confusing from the user's point of view. Since this phenomenon cannot occur in real golf, having the virtual golf ball and the real golf ball together on the floor screen 180 reduces the reality of screen golf. In this embodiment, the golf ball trapping unit 190 is provided to solve the above problems. The golf ball trapping unit 190 is installed in the movement path of the actual golf ball hit by the user (mainly, meaning hitting by putting), so that the golf ball can be captured before moving to the area where the floor screen 180 is disposed. there is. As a result, the real golf ball cannot roll on the floor screen 180 and only the virtual golf ball is displayed on the floor screen 180, thereby improving the reality of screen golf.

Hereinafter, a detailed structure of the golf ball capturing unit 190 capable of capturing a golf ball will be described. However, the structure of the golf ball capturing unit 190 described below is to cite several examples, and various structures not described below may be applied to the golf ball capturing unit 190 .

(191) can be implemented. The inclined surface 191 is inclined in such a way that the height is lowered toward the hitting area 110 . Therefore, when putting is made in the striking area 110 , as shown in FIG. 2( b ), the putt actual golf ball RB leaves the striking area 110 and the inclined surface 191 of the intermediate area 120 . ), and the golf ball RB does not advance in the direction in which the front screen 160 is installed by the inclined surface 191 and returns to the hitting area 110 direction. A recovery port 191a may be formed at the lower end of the hitting area 110, and in this case, the golf ball RB may be recovered by the recovery port 191a. The recovered golf ball may be provided to the hitting mat 111 by a separate means not shown in the drawings to be used for subsequent hitting by the user.

Referring to FIG. 3 , the golf ball capturing unit includes a golf ball capturing unit capable of capturing an actual golf ball RB and a muting unit for reducing a sound generated when capturing a golf ball. The golf ball trapping means may be implemented as an inclined surface 191 formed in the intermediate region 120 , and a mute member 192 may be attached to the inclined surface 191 as the mute means. As the mute member 192, a buffer member or a sound-absorbing member may be used. The cushioning member or the sound-absorbing member may block the sound from being generated due to the collision between the golf ball RB and the inclined surface 191 when the golf ball RB exits the striking area 110 and enters the inclined surface 191 . Since it is rare in real golf to make a sound while a putt golf ball rolls, if a sound is generated while the putt golf ball (RB) is captured by the golf ball trapping unit, the reality of screen golf can be reduced. Mute means such as a member or a sound-absorbing member can serve to provide the same reality as in actual golf by blocking the sound when the golf ball RB is captured. As the cushioning member, a mat-shaped glass wool that can reduce impact sound may be used, and as the sound-absorbing member, there are many small holes, so that sound waves can enter and be absorbed without coming back again. Text, glass fiber, felt, etc. can be used. there is.

Referring to FIG. 4 , the golf ball capturing unit includes a golf ball capturing means capable of capturing an actual golf ball RB, and as the golf ball capturing means, between the striking area 110 and the intermediate area 120 . A groove 191 may be formed. The groove 191 may have a recessed structure as if a groove is formed. Accordingly, the golf ball RB that leaves the striking area 110 and goes toward the intermediate area 120 may be trapped by being trapped in the groove 191 . . The groove 191 may have a flat bottom surface or may have an inclined bottom surface as a modification different from that shown in FIG. 4 . In addition, although not shown in the drawings, a recovery port capable of recovering a golf ball may be formed at the lower end of the striking area 110 in a structure similar to that shown in FIG. 2 .

Referring to FIG. 5 , the golf ball capturing unit includes a golf ball capturing unit capable of capturing an actual golf ball RB and a muting unit for reducing a sound generated when capturing a golf ball. The golf ball catching means may be implemented as a groove 191 formed between the striking region 110 and the intermediate region 120, and a muting member 192 may be provided in the groove 191 as the muting means. there is. As the mute member 192, a buffer member or a sound absorbing member may be used. The buffer member or the sound-absorbing member blocks the sound from being generated due to the collision between the golf ball RB and the groove 191 when the golf ball RB leaves the hitting area 110 and is trapped in the groove 191, FIG. The same buffer member or sound-absorbing member as described with reference to 3 may be used.

Referring to FIG. 6 , the golf ball capturing unit includes a golf ball capturing means capable of capturing an actual golf ball RB, and as the golf ball capturing means, the golf ball RB is located inside the end of the striking area 110 as the golf ball capturing means. ) may be provided with a housing 191 that can accommodate. Also, a cover 191b may be attached to one side of the housing 191 . The housing 191 may have a hollow structure with an open top, and the cover 191b opens the top of the housing 191 as shown in FIG. 6(a) or as shown in FIG. 6(b). As described above, the cover 191b may close the upper portion of the housing 191 . That is, one end of the cover 191b is fixed and the opposite end is configured to rotate in a horizontal state or an inclined state using the fixed end as a rotation axis. When the opposite end is in the horizontal state, the upper portion of the housing 191 is covered and closed, and when the opposite end is in the inclined state, the upper portion of the housing 191 is opened to open the inside. Although not shown in the drawings, the housing 191 may include a driving unit for setting the cover 191b to a horizontal state or an inclined state when a specific signal is received from the controller 140 . In this case, the housing 191 may be automatically opened or closed according to the control of the controller 140 . Specifically, when the golf ball is to be captured, the golf ball rolling in the hitting area 110 is captured by opening the housing 191 , and when the golf ball is captured, the cover 191b rotates to become a horizontal state and the housing 191 . It can operate in a way that closes the

Referring to FIG. 7 , the golf ball capturing unit includes a golf ball capturing unit capable of capturing a golf ball and a muting unit for reducing a sound generated when capturing a golf ball. A housing 191 capable of accommodating the golf ball RB may be provided at the end of the striking region 110 as the golf ball trapping means. Also, a cover 191b may be attached to one side of the housing 191 . As the muting means, a muting member 192 may be provided inside the housing 191 . As the mute member 192, a buffer member or a sound absorbing member may be used. The cushioning member or sound-absorbing member blocks the sound from being generated when the golf ball is captured by the housing 191 outside the striking area 110, and the same cushioning member or sound-absorbing member as described with reference to FIG. 3 may be used.

As described above, the golf ball capturing unit for capturing the golf ball may be implemented in various ways, and accordingly, when the golf ball is blocked from moving and disappears from the user's field of view, a virtual golf ball is displayed on the floor screen 180 to display the actual putt It can replace the golf ball of The controller 140 receives information about the golf ball detected by the sensor 130 (eg, the speed at which the putt golf ball rolls, etc.) and calculates the timing at which the golf ball is captured by the golf ball capturing unit based on this. and a virtual golf ball may be displayed on the floor screen 180 according to the timing. As a result, when the golf ball hit by the user disappears, the virtual golf ball in the bottom screen 180 is displayed, so that the real golf ball can be operated to naturally connect to the virtual golf ball.

8 is a diagram illustrating a schematic structure of a virtual golf apparatus according to a second embodiment of the present invention.

Referring to FIG. 8 , the virtual golf device 200 includes a hitting area 210 , an intermediate area 220 , a detector 230 , a controller 240 , a beam projector 250 , and a screen 260 , and also The virtual golf device 200 according to the present embodiment is provided with a golf ball trapping unit 290 . Compared with the first embodiment described above, in this embodiment, the floor screen and the beam projector for the floor screen are not separately provided, and the golf ball trapping unit 290 is disposed in the vicinity of the front screen 260 in that There is a difference from the first embodiment. The present embodiment will be mainly described with reference to the above differences (for content not described, the content described in the first embodiment may be applied). In this embodiment, since the golf ball trapping unit 290 is located in the vicinity of the screen 260, the golf ball hit by the user is in the vicinity of the screen 260 via the intermediate region 120 in the striking region (110). After moving up to, the golf ball is captured by the trapping unit 290 . The structure and operation of the golf ball trapping unit 290 may be applied as it is described in the first embodiment, and a detailed description thereof will be omitted. As in the first embodiment, the rolling of the golf ball to the vicinity of the screen 260 is mainly when the user actually puts the golf ball. Because, in a blow other than putting, a blow is made to float the golf ball in order to send the golf ball away, so the actual golf ball hit in this way flies the middle area 220 rather than rolling the bottom of the middle area 220 to the screen ( 260) will collide. In the present embodiment, if the putt golf ball is captured by the golf ball trapping unit 290 while rolling and disappears, the virtual golf ball is displayed on the screen 260 immediately after being captured, so that the actual golf ball is the virtual golf in the screen 260. The effect that naturally leads to the ball is generated, thereby improving the reality of screen golf. A detailed operation method for exerting the effect that the putt golf ball leads to a virtual golf ball in the screen 260 is as follows.

9 to 13 are diagrams for explaining examples of various operating methods of the virtual golf apparatus of FIG. 8 . 9A to 9C illustrate a first operation method, FIGS. 10A to 10C illustrate a second operation method, FIGS. 11A to 11F illustrate a third operation method, and FIGS. 12A to 12D illustrate a fourth operation method 13A to 13C show a fifth operation method.

<First operation method>

Referring to FIG. 9A , in the initial stage, a screen golf player (hereinafter, referred to as a 'screen golfer') 1 has a golf club 2 and is positioned on the striking plate 211, and the striking plate 211 has an actual A golf ball RB is placed. Since hitting here mainly corresponds to 'putting', the hole cup HC, which is the target of putting, is displayed on the background screen of the screen 260 . 9A shows the screen golfer 1 just before hitting for putting.

Referring to FIG. 9B , the screen golfer 1 puts and the putt golf ball RB rolls forward. Referring to FIG. 9c , the golf ball RB rolled forward is captured by the golf ball capturing unit 290 near the screen 260 , and when the golf ball RB is captured and disappears, thereafter the screen 260 . A virtual golf ball VB is displayed. As such, when the virtual golf ball VB is displayed after the golf ball RB is captured, it can be seen that the virtual golf ball VB is displayed at almost the same time as the golf ball RB is captured and disappears with the naked eye. there is.

Here, the virtual golf ball VB may be displayed at the same time as the golf ball RB is captured and disappeared, or the virtual golf ball VB may be displayed after a while after the golf ball RB disappears. . For example, when the golf ball capturing unit 290 is very close to the screen 260, the golf ball RB disappears and a virtual golf ball VB is displayed at the same time, and the golf ball capturing unit 290 is displayed. ) is slightly away from the screen 260, the golf ball RB disappears and after a while, the virtual golf ball VB may be displayed. Alternatively, regardless of the distance between the golf ball trapping unit 290 and the screen 260, the golf ball RB disappears at the same time and the virtual golf ball VB may be displayed. However, even if the virtual golf ball VB is displayed with a slight time difference after the golf ball RB disappears, if the time difference is not large, the virtual golf ball RB disappears and almost simultaneously with the naked eye. VB) can be recognized as being displayed. Therefore, since there is no significant difference between the display of the virtual golf ball VB at the same time the golf ball RB disappears, or the display of the virtual golf ball VB after a while after disappearing, there is no significant difference between the two. The description of 'after the ball (RB) is captured' may mean 'at the same time as the catch' in some cases.

As described above, in the operation method according to this embodiment, after the actual golf ball RB is put, the virtual golf ball VB is not displayed on the screen 260 immediately, and the actual golf ball RB is not displayed on the screen 260. It is characterized in that the virtual golf ball VB is displayed on the screen 260 as soon as it is captured and disappeared by the golf ball capturing unit 290 .

In other words, for convenience of explanation, the point at which the actual golf ball RB is hit (mainly meaning 'putting') is referred to as the first time point T1, and the actual golf ball RB from the first time point T1 is The time taken from rolling to being captured by the golf ball capturing unit 290 is referred to as the intermediate time ΔT, and the time at which the actual golf ball RB is captured by the golf ball capturing unit 290 is referred to as the second time point ( When T2; T2 = T1 + ΔT) (T1, ΔT, and T2 are used as the same meaning in other operating methods below), the operational characteristics according to this embodiment are displayed on the screen 260 during the intermediate time ΔT. The point is that the virtual golf ball VB is not displayed. The effects of this operation method are as follows.

Screen golf can be seen as a mixture of the real world and the virtual world. That is, it can be seen that the screen golfer 1 hits the actual golf ball RB, which is not different from the hitting action performed in the outdoor field, indicating the real world. In contrast, the movement of the golf ball after hitting is not by the actual golf ball RB, but by the virtual golf ball VB in the screen 260, it can be seen that the virtual world is represented. If the virtual golf ball VB is displayed on the screen 260 during the intermediate time ΔT, the screen golfer 1 can determine how the real golf ball RB is formed after hitting the real golf ball RB. It becomes indifferent to whether it moves and only pays attention to the movement of the virtual golf ball VB displayed on the screen 260 . That is, the interest of the screen golfer 1 is suddenly switched from the real world to the virtual world before and after the moment of hitting the real golf ball RB. In this way, when the interest of the screen golfer 1 is suddenly switched, the real world and the virtual world are cut off from each other, and the gap between them increases, which causes the screen golfer 1 to actually play in an outdoor field. It becomes difficult to experience the reality that seems to exist.

However, if the virtual golf ball VB is not displayed on the screen 260 for the intermediate time ΔT as in the present embodiment, the screen golfer 1 plays the screen 260 even after hitting the actual golf ball RB. ) to follow the movement of the actual golf ball (RB) with the eye, and when the actual golf ball (RB) disappears by the golf ball trapping unit 290 near the screen 260, naturally the screen 260 The gaze is moved to , and attention is paid to the movement of the virtual golf ball VB displayed on the screen 260 from that moment. As a result, the screen golfer 1's interest naturally leads from the real world to the virtual world, reducing the gap between the real world and the virtual world, and from the screen golfer 1's point of view, reality as if playing in an outdoor field. can feel strongly.

According to this operation method, since the virtual golf ball VB must be displayed after the actual golf ball RB is captured by the golf ball capturing unit 290, the actual golf ball RB is captured by the golf ball. It is necessary to know when to be captured by unit 290 . For this purpose, the golf ball capturing unit 290 may be provided with a separate sensing means for detecting whether the golf ball RB is captured. In this case, when the sensing means detects that the golf ball (RB) is captured, a predetermined signal is transmitted to the controller 240, and when the controller 240 receives the signal, a virtual golf ball ( VB) can be controlled to be displayed.

Alternatively, a separate detection sensor may be provided to determine the capture point of the golf ball RB. As the detection sensor, a camera capable of detecting a moment when the golf ball RB disappears while tracking the movement of the golf ball RB may be used. As in the case where the golf ball trapping unit 290 is provided with a detection means for detecting whether the golf ball RB is captured, when the detection sensor detects that the golf ball RB is captured, a predetermined value is sent to the controller 240 . transmits the signal, and the controller 240 may control the virtual golf ball VB to be displayed on the screen 260 upon receiving the signal. The detection sensor may be configured to additionally sense even the moving speed or direction of the golf ball RB when it is captured while simultaneously sensing whether the golf ball RB is captured. 5 It can be used in operation method, etc.

Here, the detection means or the detection sensor are not essential, and even without them, the additional detection information can be obtained. For example, the sensor 230 may detect a movement speed or direction when the golf ball RB is captured. Alternatively, in order to calculate the trajectory of the virtual golf ball VB to be displayed on the screen 260, the speed of the golf ball RB in the sensor 230 immediately after the screen golfer 1 puts the golf ball RB. , direction, spin, etc. are sensed. From the sensed information, when the actual golf ball RB is captured by the golf ball capturing unit 290 and the movement speed or direction when captured can be calculated. there is.

<Second operation method>

Referring to FIG. 10A , the screen golfer 1 is actually hitting the golf ball RB at a first time point T1 . Compared with FIG. 9A , there is a difference in that a virtual golf ball VB is displayed on the screen 260 . In this way, when the screen golfer 1 displays the virtual golf ball VB on the screen 260 before hitting, the screen golfer 1 clearly grasps where the golf ball VB is currently located before hitting. can

Referring to FIG. 10B , immediately after the screen golfer 1 puts the actual golf ball RB, the virtual golf ball VB disappears from the screen 260, and the real golf ball VB disappears from the first time point T1. During the intermediate period ΔT until the ball RB is captured by the golf ball capturing unit 260 and disappears, the virtual golf ball VB is not displayed on the screen 260 . Referring to FIG. 10C , after the second time point T2 at which the actual golf ball RB is captured and disappears, the virtual golf ball VB is displayed again on the screen 260 . Consequently, the operation in the steps shown in Figs. 10B and 10C is the same as the operation in the corresponding step in the first operation mode.

According to this embodiment, by displaying the virtual golf ball (VB) on the screen 260 before putting the actual golf ball (RB), the screen golfer (1) before hitting where the virtual golf ball (VB) location can be easily identified. In addition, by not displaying the virtual golf ball VB on the screen 260 for an intermediate time ΔT from the moment the hit is made, the screen golfer 1 pays attention to the screen 260 instead of the real golf ball (RB) continues to attract attention. As a result, similar to the case of the first operation method, it is possible to reduce the gap between the real world and the virtual world, and to give reality as if playing in an outdoor field.

<3rd operation method>

11A and 11B , the operation during the first time point T1 and the intermediate period ΔT is the same as the second operation method. That is, at the first time point T1, the virtual golf ball VB is displayed on the screen 260, but after the first time point T1, the virtual golf ball VB disappears from the screen 260, and the intermediate period ( ΔT) is not displayed. Here, the operation during the first time point T1 and the intermediate period ΔT is the same as the first operation method, so that the virtual golf ball VB is not displayed on the screen 260 from the first time point T1. It can also be configured.

Referring to FIG. 11C , if the putted golf ball RB rolls toward the screen 260 and is captured by the golf ball capturing unit 290 and disappears, the screen 260 after being captured and disappears displays a virtual golf ball ( VB) is displayed. Here, assuming that the golf ball RB is not captured by the golf ball capturing unit 290, the golf ball RB moves to the screen 260 as putt by the user and 'expects the point where it collides with the screen 260' Referring to the 'collision point', the virtual golf ball VB is displayed on the screen 260 from the expected impact point or the vicinity of the expected impact point.

In this way, when the virtual golf ball VB appears on the screen 260 at the expected collision point when it is assumed that the actual golf ball RB collides with the screen 260, the virtual golf ball VB appears on the screen 260. It can give a more natural feeling of connecting to the golf ball (VB), and further, when the golf ball trapping unit 290 and the screen 260 are adjacent to each other, the golf ball RG is sucked into the screen 260 to make a virtual golf It can give a feeling of appearing as a ball (VB). As a result, the gap between the real world and the virtual world is further reduced, maximizing the reality as if you are actually playing outdoors.

Referring to FIG. 11D , in order to give a feeling that the actual golf ball RB is sucked into the screen 260, the virtual golf ball VB is preferably displayed from the same point as the expected collision point, but the virtual golf It may not be technically easy to precisely match the initial display point of the ball VB and the expected collision point. If the virtual golf ball VB is displayed in the vicinity of the expected collision point within a predetermined range, it is difficult for the human eye to accurately recognize that the expected collision point and the display start point of the virtual golf ball VB are different. Therefore, if a virtual golf ball VB is displayed in the vicinity of the expected collision point within a range that a person with normal vision cannot recognize that the expected collision point and the display start point are different, sufficient reality is provided. can feel it As shown in FIG. 11D, if the radius of the actual golf ball RB is 'R', the virtual golf ball VB is preferably displayed within the range of about 5R from the expected collision point, more preferably is preferably displayed within the range of approximately 3R.

11E each shows a modified example of the third operation method.

Referring to FIG. 11E , the background screen of the screen 260 may be displayed by horizontally or vertically moving from the second time point T2 as a starting point. According to the third operation method, at the second time point T2 , the virtual golf ball VB starts to be displayed on the screen 260 from the expected collision point or the vicinity of the expected collision point. However, since the movement of the virtual golf ball VB follows the result calculated by the controller 240, the position at which the virtual golf ball VB starts to be displayed (hereinafter, referred to as a 'start position') can be arbitrarily adjusted. can't Accordingly, the starting position and the expected collision point may not coincide. In this modified example, the starting position is moved to the expected collision point to solve this problem. That is, as shown in FIG. 11E , by moving the background screen of the screen 260 , the starting position at which the virtual golf ball VB starts to be displayed on the screen 260 is determined as the expected collision point (golf ball RB). Assuming that it is not captured by the golf ball capturing unit 290, it can be made to correspond to the point where it rolls to the screen 260 and collides).

Specifically, as shown in (I) of FIG. 11E, in the state before moving the background screen of the screen 260, the starting position and the expected collision point are 'X' in the horizontal direction and 'Y' in the vertical direction by 'X' in the vertical direction. If there is a difference, as shown in (II) of FIG. 11E, by moving the background screen of the screen 260 by 'X' in the horizontal direction and 'Y' in the vertical direction, the start position and the expected collision point can be matched. can As described above, the present modified example shows an operation method of matching the start position and the expected collision point by vertically moving or horizontally moving the background screen displayed on the screen 260 , or performing both vertical and horizontal movements at the same time.

11F each shows another modified example of the third operation mode.

In this modified example, almost the same principle as that described with reference to FIG. 11E is applied, but when the background screen of the screen 260 suddenly moves horizontally or vertically from the second time point T2 as a starting point ((I in FIG. 11F)) In the case of changing from (III) in FIG. 11F), considering that a sudden screen change may be perceived unnaturally by the user, as shown in (II) of FIG. 11F, an intermediate screen during the background screen change is provided. point is characteristic. The intermediate screen may be appropriately provided between the first and second time points T1 and T2, and may be provided in a singular or a plurality. The number of provided intermediate screens may be configured to increase as the time difference increases according to the time difference between the first and second time points T1 and T2.

<Fourth operation method>

12A and 12B , the operation during the first time point T1 and the intermediate period ΔT is the same as the second operation method. That is, the virtual golf ball VB is displayed on the screen 260 at the first time point T1, but after the first time point T1, the virtual golf ball VB disappears from the screen 260, and the intermediate period ( It is not displayed during ΔT). Here, the operation during the first time point T1 and the intermediate period ΔT is the same as the first operation method, so that the virtual golf ball VB is not displayed on the screen 260 from the first time point T1. It can also be configured.

12c, if the put golf ball (RB) rolls toward the screen 260 and is captured by the golf ball trapping unit 290 and disappears, after being captured and disappearing, the screen 260 displays a virtual golf ball ( VB) is displayed. According to this operation method, assuming that the golf ball RB is not captured by the golf ball capturing unit 290 , the golf ball RB moves to the screen 260 as putt by the user and collides with the screen 260 . When the direction is referred to as 'anticipated collision direction', the angle at which the background screen is displayed on the screen 260 is changed to correspond to the expected collision direction.

Specifically, as shown in (I) of Fig. 12c, assuming that the actual golf ball RB is not captured, the direction (expected collision direction) colliding with the screen 260 and the display on the screen 260 When the moving direction of the virtual golf ball VB is significantly different, it can be considered as if the golf ball RB is unnaturally refracted as the golf ball RB enters the screen 260 when the screen golfer 1 sees it. there is. In order to prevent such unnaturalness, in this operation method, the expected collision direction matches the direction in which the virtual golf ball VB displayed on the screen 260 moves. That is, as shown in (II) of FIG. 12C , by changing the angle at which the background screen on the screen 260 is viewed, the direction in which the virtual golf ball VB moves on the screen 260 is changed. The effect occurs, and as a result, the direction of movement of the virtual golf ball VB displayed on the screen 260 can be matched with the expected collision direction.

12D shows a modified example of the fourth operation method, respectively. When the angle at which the background screen of the screen 260 is viewed is suddenly changed from the second time point T2 as a starting point (changed from (I) in FIG. 12D to (III) in FIG. 12D), a sudden screen change occurs when the user In consideration of the fact that it may be perceived unnaturally by the user, in this modified example, an intermediate screen during the background screen change is provided as shown in (II) of FIG. 12D. The intermediate screen may be appropriately provided between the first and second time points T1 and T2, and may be provided in a singular or a plurality. The number of provided intermediate screens may be configured to increase as the time difference increases according to the time difference between the first and second time points T1 and T2.

<Fifth operation method>

This operation method relates to how to calculate the movement of the virtual golf ball (VB) shown on the screen 260, and it is somewhat different in nature from the previous operation method in that it is not specifically revealed to the outside. This operation method may be used alone, or may be used in combination with the first to fourth operation methods, and FIG. 13 shows an example in combination with the second operation method.

13A and 13B , the operation during the first time point T1 and the intermediate period ΔT is the same as the second operation method. That is, at the first time point T1, the virtual golf ball VB is displayed on the screen 260, but after the first time point T1, the virtual golf ball VB disappears from the screen 260, and the intermediate period ( ΔT) is not displayed. Here, the operation during the first time point T1 and the intermediate period ΔT is the same as the first operation method, so that the virtual golf ball VB is not displayed on the screen 260 from the first time point T1. It can also be configured.

Referring to FIG. 13C , the virtual golf ball VB is displayed on the screen 260 immediately after the second time point T2 at which the golf ball RB is captured and disappeared by the golf ball capturing unit 290 . The characteristic of this operation method lies in the movement of the virtual golf ball VB displayed on the screen 260 , that is, the trajectory. Specifically, when the golf ball RB is putt at the first time point T1 and the trajectory S for the virtual golf ball VB is calculated based on the hitting result, the trajectory S ), which is actually displayed on the screen 260, except for the trajectory S1 from the first time point T1 until a predetermined time elapses, and only the trajectory S2 after the predetermined time. For example, the predetermined time may be an intermediate period ΔT from the time of putting the golf ball RB to the time when the putt golf ball RB is captured by the golf ball capturing unit 290, In this case, only the trajectory S2 from immediately after the second time point T2 is displayed on the screen 260 .

Considering that the trajectory S1 during the intermediate period ΔT in the calculated total trajectory S corresponds to the trajectory indicating until the actual golf ball RB moves from the hitting point to the screen 260, the above By omitting and not displaying the trajectory S1 , the omitted trajectory S1 can be viewed as being replaced with an actual trajectory indicated until the actual golf ball RB rolls to the screen 260 . Therefore, the overall trajectory is expressed by the actual trajectory of the real golf ball RB outside the screen 260 and the trajectory S2 in the image indicated by the virtual golf ball VB on the screen 260. . As a result, the movement of the actual golf ball RB naturally leads to the movement of the virtual golf ball VB on the screen 260 , and the actual golf ball RB is connected to the screen 260 to create a real The gap between the world and the virtual world is further reduced, and the reality as if you are actually playing outdoors can be maximized.

Although specific embodiments of the present invention have been described above, those of ordinary skill in the art to which the present invention pertains can understand that the present invention can be implemented in a modified form within a range that does not depart from the essential characteristics of the present invention. will be. For example, the first to fifth operation methods may not be used separately, but may be used in combination. For example, the operation method of moving the background screen (refer to FIG. 11E and related description) to match the expected collision point and the starting position where the virtual golf ball is displayed is the expected collision direction and the direction in which the virtual golf ball moves on the screen. It can be used in combination with an operation method of rotating the background screen (see FIG. 12C and related description) to match the .
