Therefore, the embodiments disclosed in this specification should not be limited to the shapes shown in the drawings unless otherwise specified, and should be understood to include some degree of modification.

1 and 2 are diagrams illustrating a process of a mini-map display method according to an embodiment of the present invention.

Referring to FIG. 1 , the mini-map display method according to an embodiment of the present invention includes three steps of selecting a target region (S10), forming a mini-map (S20), and displaying a grid (S30). In the target region selection step (S10), a target region to be expressed as a minimap is selected. The mini-map may represent the entire area of a specific object that can be expressed with the mini-map, or may represent a part of the entire area. In the mini-map forming step (S20), a mini-map for the selected target area is formed, and in the grid display step (S30), a grid is displayed on the formed mini-map. The mini-map formation step (S20) and the grid display step (S30) are not performed in a fixed order, and in some cases, a mini-map may be formed after displaying a grid.

2 (commonly referred to as 2a, 2b, and 2c) shows a process of forming a golf course mini-map in screen golf to which the mini-map display method of FIG. 1 is applied. For example, each step of the mini-map display method of the present invention will be examined in more detail.

Referring to FIG. 2A , in a first step, a target area, which is a target of a mini-map, is selected in a golf course. Golf is played by hitting a golf ball with a tee shot and putting the golf ball into a hole cup on a green, and it is a game in which the number of hits from the tee shot to the golf ball being put into the hole cup determines the outcome of the game. In general, a golf game consists of 18 holes as one unit, and the golf course constituting each hole has various golf courses such as Teeing Ground, Through the Green, Green, and Hazard. consists of zones.

The minimap is mainly used for the convenience of gamers in computer games, and is a kind of reduced map in which the place where the game is being played is reduced like a map. Recently, it is used not only in computer games but also in various fields, and in screen golf, a mini-map in which a golf course is reduced by hole unit is used. In screen golf, a mini-map can be of great help to the user's play. While the distance from the tee shot location to the hole cup on the green is quite far, the screen displays only a limited area around the point where the golf ball is placed. The position where the hit golf ball is located is curious about how much it corresponds to in the entire golf course. This curiosity can be solved by providing a mini-map that represents a reduced golf course.

The target area of the mini-map may be the entire golf course area or only a part of the entire area, and FIG. 2A shows a case where a part of the entire area is the target area. The target area is not always fixed, and the target area can be changed while screen golf is being played, and when the target area is changed, the mini-map indicating the corresponding target area is also changed.

Referring to FIG. 2B, in the second step, a minimap for the selected target region is formed. It is preferable that the mini-map is reduced to include the overall outline of the target region rather than showing the target region in detail. The mini-map may be formed by extracting necessary information from a database storing data related to a corresponding golf course. Alternatively, a mini-map corresponding to the corresponding target area for each target area of the corresponding golf course may be formed in advance, stored in the database, etc., and then the mini-map may be extracted from the database. Since mini-maps have been conventionally used in screen golf, mini-maps can be easily formed using conventional techniques and the like.

Referring to FIG. 2C , in the last step, a grid is displayed on the minimap. The grid includes a plurality of horizontal lines L1 extending in the horizontal direction and a plurality of vertical lines L2 extending in the vertical direction. Although the horizontal line L1 and the vertical line L2 are shown perpendicular to each other in FIG. 2C, these lines are not necessarily perpendicular to each other. That is, the two types of lines constituting the grid do not necessarily have to be horizontal and vertical lines, and these lines may be non-straight lines.

The plurality of horizontal lines L1 may be disposed at regular intervals from each other, and the plurality of vertical lines L2 may also be disposed at regular intervals from each other. When a plurality of lines are arranged at regular intervals, users can easily grasp the distance between objects appearing on the mini-map. For example, when the distance between the horizontal lines L1 adjacent to each other is 1 square, the object A and the object B are located on different horizontal lines L1, respectively, and the distance between the horizontal lines where they are located is 5 squares. Then, it can be easily seen that object A and object B are separated by the distance indicated by 1 cell multiplied by the number of cells (for example, if 1 cell represents a distance of 10 m, they are 50 m (10 m × 5) apart). In addition, if the different A, B, and C objects are located on different vertical lines L2, the distance between A and B objects is 3 spaces, and the distance between A and C objects is 6 spaces, A and B objects It is easy to see that the distance between them is half of the distance between objects A and C. In this way, by displaying the grid on the mini-map, there is an effect of easily obtaining more various information from the mini-map, such as distance information.

Hereinafter, as a specific example of a system to which a mini-map displaying a grid is applied, a virtual golf system provided in a screen golf course will be described.

3 is a diagram showing a schematic structure of a virtual golf system according to an embodiment of the present invention, and FIG. 4 is a block diagram showing the relationship between major components of the virtual golf system of FIG. 3 .

Referring to FIG. 3 , the virtual golf system 100 according to the present embodiment includes a hitting plate 110, a sensing unit 120, an input unit 130, a simulator 140, and a display unit 150.

The hitting plate 110 corresponds to a hitting zone in which a golf ball is placed and hit. A hitting mat 111 is provided on the hitting plate 110, and a golf ball for hitting is provided to the user by a separate golf ball supply means or the like on the hitting mat 111.

The sensing unit 120 detects the movement of the golf ball hit by the user and grasps overall state information about the golf ball hit by the user. Any sensing means such as a detection sensor may be used as long as it can be detected. Various sensing methods such as image sensing, light emitting/light receiving sensing, and laser sensing may be applied using the above-described sensing means, and state information of a golf ball hit by a user may be grasped through this sensing method. The camera or detection sensor may be used alone or together, and may be used alone or in multiple units as needed.

The input unit 130 is for receiving various types of information from a user, and a keyboard or mouse may be used. In screen golf, there are cases in which information input from the user is required, such as when the user inputs his or her ID or password, or when the user selects a golf course or level of difficulty to play. For this purpose, the input unit 130 is are provided

As shown in FIG. 4 , the simulator 140 may include a calculation unit 141 , an imaging unit 142 and a database 143 . When the user hits the golf ball, the calculation unit 141 may receive state information about the hit golf ball, and then simulate and calculate the trajectory of the golf ball based on the received state information. The image unit 142 may implement a golf image to be shown to the user and deliver it to the display unit 150 . A screen according to an image generated by the imaging unit 142 may include a main screen and a sub screen. A golf course or golf ball may be displayed on the main screen, and a mini-map may be displayed on the sub screen. The imaging unit 142 may simultaneously process the main screen and the sub-screen without a separate configuration, or may include a separate mini-map unit dedicated to processing the mini-map of the sub-screen. The database 143 may store information necessary for the operation of the calculation unit 141 and the imaging unit 142 .

The display unit 150 includes a beam projector 151 and a screen 152 . The beam projector 151 projects golf-related images and provides them to the screen 152, and the screen 152 displays the projected images to the user.

The virtual golf system 100 is a device installed in a screen golf course to play screen golf, and when a user plays screen golf, the virtual golf system 100 operates as follows.

First, when the user hits the golf ball, the sensing unit 120 detects a physical state such as the speed or moving direction of the golf ball hit by the user. The information sensed by the sensor 120 is transmitted to the simulator 140, and the calculation unit 141 of the simulator 140 assumes that the user hits a golf ball at an actual outdoor golf course based on the transmitted information. At this time, it is calculated what trajectory the golf ball will show. The image unit 142 implements an image of the golf ball moving according to the calculated trajectory, and the display unit 150 displays the image and provides it to the user.

The golf course provided for the user's play on the screen golf course may be an identical reproduction of an actual golf course as a model, or a non-real virtual golf course may be arbitrarily created. In any case, the image of the golf course the user is playing is displayed on the main screen of the screen 152, and when the user hits a golf ball and the trajectory of the hit golf ball is calculated, the main screen of the screen 152 displays the golf course image. After the golf ball moves along the calculated trajectory on the golf course, an image stopping at a predetermined point is displayed. As such, since the related image is displayed on the screen 152 by focusing on the golf ball, the area mainly displayed on the screen 152 among the golf course areas of the golf course is the golf ball centered on the golf ball and the area around it. And, this display area changes according to the movement of the golf ball. However, in order to target the golf course, it is necessary to grasp additional information such as the location of the hole cup, the final target point, and the distance between the golf ball and the hole cup, as well as the area where the golf ball is currently located. The screen may lack this information. Therefore, additional additional information needs to be provided for user convenience. To this end, as shown in FIG. 3 , a mini-map screen may be provided as a sub-screen in addition to the main screen on the screen 152 . Also, as described above, the mini-map screen provided herein may be a mini-map displaying a grid capable of providing various information. Specifically, a minimap displaying various types of grids may be provided as follows.

5 to 10 are diagrams illustrating various examples of minimaps that may be provided in the virtual golf system of FIG. 3 .

Referring to FIG. 5 , the location of the golf ball G and the hole cup HC of the user currently playing may be displayed along with a grid on the mini-map, and also, when the user hits the golf ball G, the golf ball ( As the location of G) is changed, the target area displayed on the minimap may be changed. Specifically, as shown in FIG. 5(a), when a user makes an initial tee shot on a specific hole on a golf course, the golf ball G is at the tee shot position farthest from the hole cup HC, and the minimap is formed for the entire area of the corresponding golf course. As shown in FIG. 5(b) , when the golf ball G moves approximately halfway from the golf course toward the hole cup HC as a result of the user hitting the golf ball G, the mini-map shows the location of the corresponding golf course. It is formed for about half of the area. As shown in FIG. 5(c), when the golf ball G approaches the hole cup HC and reaches the green area, a mini-map is formed targeting the green area of the corresponding golf course.

As such, the target area of the golf course displayed on the mini-map may vary according to the relative position between the golf ball G and the hole cup HC, and the user may determine the relative position between the golf ball G and the hole cup HC. Relationships can be easily identified on the minimap. In particular, since the grid is displayed on the mini-map according to the present embodiment, the user can determine the relative distance between the golf ball G and the hole cup HC by checking how many spaces are apart on the grid. The grid includes a plurality of horizontal lines (L1) and vertical lines (L2) spaced apart from each other at regular intervals. Both the vertical and horizontal separation distances can be identified. For example, when the distance between the horizontal lines L1 adjacent to each other is named as 1 column, the hole cup HC and the golf ball G are located on different horizontal lines L1 and between the horizontal lines where they are located. If is 10 squares, the horizontal distance between the hole cup HC and the golf ball G is as much as the number of squares multiplied by the distance represented by 1 square (for example, if 1 square represents a distance of 10 m, 10) is easily identified. Similarly, if the hole cup HC and the golf ball G are located on different vertical lines L2 and the interval between them is 3 squares, the vertical distance between the hole cup HC and the golf ball G is 30 m (1 square). It is easy to figure out that this represents a distance of 10 m). This calculation assumes that the hole cup HC and the golf ball G are positioned on the horizontal line L1 or the vertical line L2, but as shown in FIG. 5, the hole cup HC and the golf ball ( Even when G) is not located on the horizontal line L1 or the vertical line L2, the target is the horizontal line L1 or vertical line L2 adjacent to the hole cup HC and the golf ball G. Thus, it is possible to roughly grasp the distance between the hole cup HC and the golf ball G.

In the above example, the case where the distance indicated by 1 cell both horizontally and vertically was 10 m, but the distance indicated by 1 cell horizontally/vertically does not have to be the same. For example, each square represents 10 m in the horizontal direction and each square represents 5 m in the vertical direction, so that the distance indicated by the line spacing (1 square) on the grid may be set to be different from each other in the horizontal direction and the vertical direction. In addition, the distance indicated by the line spacing (one cell) on the grid is not always constant and may be set to vary according to the target area indicated on the minimap. For example, the distance indicated by the interval between the horizontal lines L1 in Fig. 5 (a) is 10 m, the distance indicated by the interval between the horizontal lines L1 in Fig. 5 (b) is 5 m, and in Fig. 5 (c) In this case, the distance indicated by the spacing between the horizontal lines L1 is 2 m, and in this way, the distance indicated by the line spacing (one square) on the grid can be set differently. In this way, since the distance indicated by one square may vary depending on the direction and/or the target area indicated on the mini-map, the distance indicated by one square may be indicated in numbers inside or near the mini-map. there is.

The positions of the hole cup HC and the golf ball G are important information to be displayed on the mini-map. From the user's point of view, the positional relationship between the hole cups HC and the golf balls G can be intuitively easily grasped by displaying the grid. When positioned, the positional relationship can be clearly revealed. Considering this point, the grid may be displayed so that the hole cup HC and the golf ball G may be located on the line constituting the grid. For example, when the distance between the hole cup HC and the golf ball G in a predetermined direction (horizontal or vertical direction, etc.) (which may be simply indicated as 'D' for convenience in the following description) is '50 m' , If the distance represented by the interval (1 square) between the lines (which may be simply marked as 'd' for convenience in the following description) is set to 10 m, the hole cup HC and the golf ball G are placed on the grid line While displaying, four lines may be displayed between the hole cup HC and the golf ball G. Alternatively, when the distance (D) between the hole cup (HC) and the golf ball (G) in a predetermined direction (horizontal or vertical direction, etc.) is '50m', the distance (d) indicated by the interval (1 square) between the lines is 5m When set to , nine lines can be displayed between the hole cup HC and the golf ball G while displaying the hole cup HC and the golf ball G on the grid line. In summary, if the value d is set so that the value (n) when D is divided by d is an integer, the hole cup (HC) and the golf ball (G) are displayed on the grid line, and the hole cup (HC) and the golf ball ( G), n-1 grid lines may be displayed at equal intervals between them. Here, since the position of the hole cup HC is fixed and the position of the golf ball G becomes the landing position after moving according to the trajectory calculated by the calculator 141, the distance 'D' is calculated by the calculator 141 ) can be calculated from

Referring to FIG. 6( a ) , when a plurality of users play together, golf ball positions of the plurality of users may be displayed together on the mini-map. Although screen golf can be played alone, it is often played in such a way that a plurality of users form a team and compete against each other. In the case of team play, users may want to know the current match situation between their own team and the opposing team, and when a grid is displayed on the mini-map, these users' needs can be easily met. For example, assuming that four users A, B, C, and D play as a team of (A, B) and (C, D), as shown in FIG. 6 (a), the minimap has a grid. is displayed, and the position of each golf ball A, B, C, and D together with the position of the hole cup HC may be displayed. Since the distances between the golf balls of A, B, C, and D and the hole cups HC can be identified through the grid, and also the positions of the golf balls of A, B, C, and D can be identified, users can determine their It is possible to easily grasp the game situation in the team and the opponent's team.

Referring to FIG. 6(b), the mini-map targets the entire golf course of a specific hole, but the location at the point where the golf ball G is hit every time until a specific user holes in from the first hit (tee shot) is displayed. can make it In this way, if the position when the user hits the golf ball is displayed as a predetermined path R, the user can grasp the course of hitting through which path until hole-in, so that it can be referred to later when targeting the course.

Referring to FIG. 6(c), the mini-map not only displays the progress of hitting through which path (R1) until the user hole-in, but also shows which path (R2) the user played on the same course in the past. The progress of hitting through can be displayed. The past play may be the progress of attacking the course during the best play in the past, or the progress of attacking the course during the worst play in the past. In this way, by displaying the progress of the user's past play together with the progress of the current play, the user can compare the current/past play result and refer to the future course strategy.

Referring to FIG. 7, a grid is added to the mini-map, the positions of the golf ball G and the hole cup HC are displayed, and distance information between the golf ball G and the hole cup HC is directly displayed in numbers. can As described above, from how many horizontal lines L1 are arranged between the golf ball G and the hole cup HC and how much distance the 1-space interval between adjacent horizontal lines L1 represents , The horizontal distance between the golf ball (G) and the hole cup (HC) can be ascertained. In addition, from how many vertical lines L2 are arranged between the golf ball G and the hole cup HC and how far the 1-space interval between adjacent vertical lines L2 represents, the golf ball ( A vertical distance between G) and the hole cup HC may be determined. In addition, the distance between the golf ball G and the hole cup HC can be calculated from the horizontal distance and the vertical distance. However, since it is not easy for a user who is concentrating on playing screen golf to calculate the distance while looking at the mini-map, the distance between the golf ball (G) and the hole cup (HC) is directly calculated near the mini-map (or inside the mini-map). It may be indicated numerically.

In addition, as shown in FIG. 7, when the golf course is viewed in a plan view, there seems to be no height difference between the positions of the golf ball G and the hole cup HC, but in reality, the height difference between the golf ball G and the hole cup HC There can be significant height differences between locations. When there is a difference in height between the positions of the golf ball G and the hole cup HC, the golf ball must be hit in consideration of this difference. For example, when the distance in the plane between the golf ball G and the hole cup HC is D and the height difference is 0, and the distance in the plane between the golf ball G and the hole cup HC is D and When comparing the case where the height difference is H, the former strikes the golf ball at a distance of D, but the latter hits the golf ball at a distance of D±α in consideration of the factor according to the height difference (H). to hit the target. Therefore, since the information on the height difference between the positions of the golf ball G and the hole cup HC is also important to the user, the distance between the golf ball G and the hole cup HC is displayed in the vicinity of the mini-map (or inside the mini-map). The height difference may be directly numerically displayed.

Referring to FIG. 8 , a grid is added to the mini-map and the positions of the golf ball G and the hole cup HC are displayed. The grid includes a plurality of different grids. For example, the grid may include a first grid including horizontal lines L1 and vertical lines L2 and a second grid including horizontal lines L1' and vertical lines L2'. The distance between the horizontal lines L1' in the first grid may be the same as or different from the distance between the horizontal lines L1' in the second grid. In addition, the interval between the vertical lines L2 in the first grid may be the same as or different from the interval between the vertical lines L2' in the second grid. When a plurality of grids are provided as described above, each grid may be displayed in a different distance unit. For example, the first grid may display the intervals between the horizontal and vertical lines L1 and L2 in units of meters, and the second grid may display the intervals between the horizontal and vertical lines L1' and L2' in units of yards. Since each user may be familiar with the meter unit display and another user may be familiar with the yard unit display, the user sees the grid displayed in the distance unit familiar to him/her and the distance between the golf ball (G) and the hole cup (HC). You can easily find the information you need.

Referring to FIG. 9, a grid is added to the mini-map and the positions of the golf ball G and the hole cup HC are displayed, and as described above with reference to FIG. 7, the gap between the golf ball G and the hole cup HC is displayed. Distance information of may be displayed. When a grid consisting of a plurality of horizontal lines L1 and a plurality of vertical lines L2 is added to the mini-map, the area displayed on the mini-map is divided into a plurality of sub-areas made of rectangular areas. In this embodiment, the plurality of sub-regions may be displayed in color. Here, the color may vary according to the height of the corresponding sub-region. As shown in FIG. 9 , red indicates a high-height region and blue indicates a low-height region, and the height between the red and blue regions may be displayed as an intermediate color between red and blue. In this way, when the sub area is displayed in color, the position of the golf ball G and the position of the hole cup HC are compared with the color of the position where the golf ball G is placed and the color of the position where the hole cup HC is located. You can roughly figure out the height difference between them. Although an example of displaying sub-regions in different colors according to height differences has been described in FIG. 9 , height differences may be displayed by using the same color and varying brightness or saturation. In this way, the height difference between sub areas can be displayed on the minimap using color, brightness, and saturation. It can also be expressed as saturation, etc.

Referring to FIG. 10 , a grid is added to the mini-map and the positions of the golf ball G and the hole cup HC are displayed. Compared to the mini-map of the previous embodiment (see FIGS. 5 to 9) displayed in 2D from a plan view, the mini-map according to the present embodiment is displayed in 3D from a perspective view. In addition, the grid of the minimap according to the present embodiment includes a plurality of first lines L1 along a first direction, a plurality of second lines L2 along a second direction, and a plurality of third lines (L2) along a third direction. L3) is included. Regarding the distance information between the golf ball G and the hole cup HC, the first and second lines L1 and L2 serve to allow the user to grasp the distance on a two-dimensional plane. In addition, the third line (L3) can act so that the user can determine the height difference between the golf ball (G) and the hole cup (HC). In this way, by expressing the mini-map three-dimensionally and composing the grid with three types of lines along different directions, the user can easily and intuitively understand the distance or height difference between objects (golf balls and hole cups, etc.) can

Although various types of grid-displayed mini-maps have been described above, this is an example for better understanding, and the grid-displayed mini-map of the present invention can be applied to other types not described here.
