Definitions
- the present invention relates to a method for playing screen baseball, and more specifically, to a method for playing screen baseball which can be progressed in a manner similar to real baseball while using a pitching mode.
- screen baseball refers to a baseball game which can be played in a manner similar to a real baseball game using a screen, on which images are being projected, and a device such as a pitching machine, a toss machine, etc., by a user who watches the images of the game being projected on the screen.
- the general mode is a “batting mode”, in which a baseball game is played according to the baseball rules such that a user becomes a batter, and as the user hits the ball discharged from a pitching machine the batting result, whether it is a hit or not, is determined and this whole process is repeated.
- the batting result is calculated depending on the position where the ball touches on the screen (hereinafter, “catching position”).
- KR 1999-0046008A discloses a virtual reality pitching system in which virtual divided strike zones are established.
- JP 2006-181335A discloses a baseball game, in which the images of catchers performing catching motions according to the positions of the balls being pitched and the images of batters batting the balls are assigned, and the positions of the pitched balls are determined for each area, and batters' batting results are constituted as a result thereof.
- KR 2015-0109614A discloses a baseball game, in which the pitching result, whether the pitched ball was a strike or ball, is determined based on the XY coordinates of a pitched ball and then converted into a score, and thereby the result is derived.
- the above method for playing a game is only a target exercise like archery and shooting, and it can hardly be considered as real screen baseball.
- the method only enables determining of strikes/balls or playing of the game simply by calculating the scores according to the level of closeness inside the strike zone, as in archery. Whether it was a hit or not may be determined in some cases, but they are irrelevant with regard to whether a pitcher, who was the user, performed an appropriate pitch according to the baseball rules, because random probability is used in most cases.
- the method is played in a mode totally different from that of a real baseball game.
- the play mode is similar to that of archery, shooting, and darts.

- the present invention has been made to solve the above problems.
- the present invention provides a method for playing screen baseball which can be progressed in a manner similar to a real baseball game according to the real baseball rules, while using a pitching mode.
- the present invention provides a method for playing screen baseball using a pitching mode, including:
- step (c) further includes (c1) calculating a ball speed based on the information confirmed in the sensor 250 by a ball speed calculation module 143 ; and step (d) further includes (d1) calculating a pitching result according to a second method, which was preset using the ball speed calculated in step (c1), by the pitching result calculation module 140 , wherein the second method preset in step (d1) is to calculate in such a manner that as the ball speed calculated in step (c1) decreases, the probability of a pitching result being a “strike” decreases while the probability of a pitching result being a “hit” increases.
- step (b) further includes projecting the information on batters, which was loaded in a player database 190 , onto the screen 300 by the screen image unit 220 .
- step (c) further includes (c3) confirming a batter level from the loaded information on batters by a batter level calculation module 141 ; and step (d) further includes (d3) calculating a pitching result according to a third method, which was preset using the confirmed batter levels calculated in step (c3), by the pitching result calculation module 140 , wherein the third method preset in step (d3) is to calculate in such a manner that as the batter level confirmed in step (c3) becomes higher, the probability of a pitching result being a “strike” decreases while the probability of a pitching result being a “hit” increases.
- step (d) calculates the pitching result by adding up a first value calculated according to the correlation between the mitt zone 10 set in step (a) and the catching position calculated in step (c), a second value using the ball speed calculated in step (c1), and a third value using the confirmed batter level calculated in step (c3), by the pitching result calculation module 140 , wherein as the sum of the added-up values increases, the probability of a pitching result being a “strike” decreases while the probability of a pitching result being a “hit” increases, and wherein the first value increases as the calculated catching position becomes farther from the center of the mitt zone 10 , the second value increases as the ball speed becomes lower, and the third value increases as the batter level becomes higher.
- step (a) the mitt zone 10 is set in such a manner that the center of the mitt zone 10 is positioned inside the strike zone 20 by the mitt zone setting module 130 .
- the pitching result is calculated to be a “swing-and-miss” or “ball” by the pitching result calculation module 140 in step (d).
- the game operation module 120 transmits a signal so that a toss machine 230 tosses a ball when a discharge signal is approved in a discharge signal device 210 .
- the method for playing screen baseball further includes: (f) projecting an event image onto the screen 300 by the screen image unit 220 when the event image is approved by an event execution module 150 ; (g) transmitting a signal by the game operation module 120 so that the toss machine 230 tosses a ball when a discharge signal is approved in the discharge signal device 210 ; (h) calculating a catching position by the catching position calculation module 142 based on the information confirmed in the sensor 250 ; and (i) calculating the event result preset corresponding to the calculated catching position by the event execution module 150 , and projecting an event image corresponding to the calculated event result onto the screen 300 by the screen image unit 220 .
- a user can enjoy a screen baseball in a manner similar to that of a real baseball.
- pitching results can be calculated using only a catching position, or using both a catching position and a ball speed, or using a catching position and a ball speed in combination with a batter level, and thus the screen baseball game can be played in a manner similar to that of a real baseball game and thus increase the user's sense of immersion and interest.
- the hit probability increases when a pitcher fails to throw a ball to the position requested by a catcher, when the ball speed becomes lower, and when it is assumed that a good batter appears on the batter's box.
- an event may be performed in some cases, and the event may be performed without additional facility by using the catching position confirmation system which is already established.
- FIG. 1 shows a conceptual diagram of a screen baseball field in which the method for playing screen baseball according to the present invention is achieved.
- FIG. 2 shows a conceptual diagram for performing the method for playing screen baseball according to the present invention.
- FIG. 3 shows diagrams illustrating a mitt zone with regard to a method for playing screen baseball according to the present invention.
- FIGS. 4 to 6 show exemplary images being projected on a screen with regard to a method for playing screen baseball according to the present invention, in which FIG. 4 shows a general image before setting a mitt zone, FIG. 5 shows an image after setting a mitt zone, and FIG. 6 shows an image while executing an event.
- FIG. 7 shows a flowchart illustrating the method for playing screen baseball according to the present invention.
- the term “catching position” refers to the position where the ball thrown by a pitcher, who is a user, toward the screen reaches and can be confirmed by various sensors.
- ball speed refers to the speed of the ball thrown by a pitcher, who is a user, toward the screen and can also be confirmed by various sensors.
- the term “pitching result” refers to the result of a batting or the result of a swing-and-miss by a virtual batter according to the baseball rules after a ball is thrown toward the screen by a pitcher, who is a user.
- the result would be calculated as either of a “strike” or “ball”, whereas in a case where the calculation was made assuming that the virtual batter performed a batting, the result would be calculated as either of a “swing-and-miss” or “hit”.
- the “hit” may be more precisely calculated, e.g., a “one-base hit”, an “extra-base hit”, etc.
- FIG. 1 shows a screen baseball field in which the method for playing screen baseball according to the present invention is achieved.
- a terminal 100 for manipulating the game mode operated by a user or operator is located in a safe area separated by a safety fence 102 .
- the terminal 100 may also possibly be located within the operation area outside the screen baseball field.
- the user can enter the game area through a gate 103 of the safety fence 102 .
- the screen baseball field includes a screen 300 , onto which the images are being projected; a discharge signal device 210 , which is in the form of a pedal, for transmitting signals for playing a game; a screen image unit 220 for providing images; and a sensor 250 for detecting ball speeds and catching positions.
- a toss machine 230 for tossing balls to a user is located in the screen baseball field (not shown in FIG. 1 ).
- the toss machine 230 delivers balls to a user after one or two bounds and thus the screen baseball can be played safely.
- the toss machine 230 may be any device capable of tossing balls to a user and may be freely selected from various conventional toss machines, and thus detailed explanation will be omitted herein.
- the sensor 250 may be any sensor as long as it can detect ball speeds and catching positions.
- the user can play the game while watching the images being projected onto the screen 300 .
- a ball is tossed to the user from the toss machine 230 , and the user catches the ball and pitches toward the screen 300 .
- ball speeds and catching positions are calculated by the sensor 250 , etc.
- the balls are dropped into the bottom thereof upon reaching the screen 300 and collected manually or automatically by a baseball collecting unit 205 and returned.
- the terminal 100 may include a game setting module 110 , a game operation module 120 , a mitt zone setting module 130 , a pitching result calculation module 140 , and an event execution module 150 .
- the user may set the game mode by the game setting module 110 .
- any one game may be selected from the group of games consisting of a 1:1 game, a 1:1:1 game, a single game, etc., which are preset in various modes.
- the game operation module 120 performs overall functions with regard to game operation. Specifically, the game operation module 120 loads information of players on a player database 190 and controls the discharge signal device 210 , screen image unit 220 , toss machine 230 , etc.
- the mitt zone setting module 130 sets a mitt zone according to the predetermined method so that the mitt zone can be projected through the screen image unit 220 .
- the mitt zone 10 is the core concept of the present invention and will be described herein below.
- the pitching result calculation module 140 calculates a pitching result, which is the result after the user's pitching, and the pitching result may be any one selected from a “strike”, a “ball”, a “swing-and-miss”, and a “hit”.
- the pitching result calculation module 140 calculates the pitching result based on the batter level confirmed by the batter level calculation module 141 , the catching position confirmed by the catching position calculation module 142 , and the ball speed confirmed by the ball speed calculation module 143 . The details of the calculation method will be described later.
- the event execution module 150 performs an event when a particular condition is met.
- an event In a case where an event is performed, the baseball being played is temporarily stopped and an image as shown in FIG. 6 is projected onto the screen 300 , in which as the user throws a ball toward the screen 300 , the catching position is confirmed by the catching position calculation module 142 , thereby confirming the event result.
- the mitt zone according to the present invention will be explained referring to FIG. 3 .
- the present invention uses two different areas, i.e., a strike zone 20 and a mitt zone 10 .
- the strike zone 20 means the strike zone in a real baseball game.
- the strike zone 20 may be in the shape of a square (left: 78 cm, right: 78 cm), but it can surely be adjusted according to other factors such as degree of difficulty of the preset game, batters, etc. It must be noted that the strike zone 20 is projected to an area which is fixed on the screen 300 .
- the mitt zone 10 is the area within which a catcher can catch balls. In other words, the mitt zone 10 refers to the area where the catcher's mitt is located.
- the mitt zone 10 is in the shape of a circle. Also preferably, the mitt zone 10 is projected so that the catcher's mitt can be located in the center of the mitt zone 10 on the image being projected on the screen 300 (see FIG. 5 ).
- the catching position of a ball thrown by a pitcher who is the user, is the center of the mitt zone 10 , it means that the ball was accurately thrown according to the catcher's sign in real baseball. Accordingly, the probability that the pitching result will be a “strike” is high while the probability that the pitching result will be a “hit” is low.
- the mitt zone 10 may be further divided into a first area 11 in the center, a second area 12 which is an intermediate area, and a third area on the external side 13 .
- the probability that the pitching result will be a “strike” becomes highest.
- the probability that the pitching result will be a “hit” is high, and if it is in the third area 13 , the probability that the pitching result will be a “hit” is highest.
- the hit when the catching position is in the second area 12 , the hit may be calculated as a “one-base hit”, whereas when the catching position is in the third area 13 , the hit may be calculated as an “extra-base hit”.
- the pitch will correspond to a careless pitch that moves away from the preset sign between the user, who is the pitcher, and the catcher (i.e., the first area 11 ), and thus the hit probability (e.g., a one-base hit, an extra-base hit, a home run, etc.) will increase.
- the hit probability e.g., a one-base hit, an extra-base hit, a home run, etc.
- the mitt zone 10 may be changed randomly, it may be changed into a course, which may act as the Achilles heel for the corresponding batter, based on the information of batters stored in the player database 190 .
- the mitt zone 10 may be set to a lower area. As such, the user can be more deeply immersed in the screen baseball.
- the center of the mitt zone 10 is preferred to be located inside the strike zone 20 .
- a catcher may request that a pitcher throw balls other than a strike in real baseball, but it is preferred to induce only strikes considering the characteristics of screen baseball which needs a speedy process.
- a game desired by a user can be set by the game setting module 110 , and the game starts by a game operation module 120 .
- the mitt zone 10 is set by the mitt zone setting module 130 .
- the mitt zone 10 may be set randomly as described above or set based on the information of batters stored in the player database 190 .
- the screen image unit 220 projects the mitt zone 10 and the strike zone 20 together onto the screen 300 , and the information of batters that can be confirmed in the player database 190 (various kinds of information including images of batters, statistical data, etc.) is projected further thereonto, and thereby the pitcher, who is the user, is now ready to pitch a ball ( FIGS. 4 and 5 ).
- the screen image unit 220 outputs an image through the screen 300 , which requests the user to operate the discharge signal device 210 .
- the toss machine 230 tosses a ball to the user.
- the user catches the tossed ball and pitches toward the center of the mitt zone 10 , which is projected onto the screen 300 .
- the sensor 250 detects information necessary for the calculation of ball speeds and catching positions.
- the pitching result may be calculated based on only a catching position, or based on both a catching position and a ball speed, or based on a catching position, a ball speed, and a batter level.
- the catching position calculation module 142 calculates a catching position based on the information confirmed in the sensor 250 . That is, the distance of the catching position from the center of the mitt zone 10 is calculated, and also whether the catching position is inside the strike zone 20 can be calculated together. In another exemplary embodiment of the present invention, whether the catching position is within the first area 11 , the second area 12 , and the third area 13 , which are explained in FIG. 3 , can be calculated.
- the pitching result calculation module 140 calculates a pitching result according to the first method preset using the correlation between the mitt zone 10 and the catching position.
- the first method in a case where the catching position is within the strike zone 20 , as the catching position becomes farther from the center of the mitt zone 10 , the probability that the pitching result will be a “strike” decreases while the probability that the pitching result will be a “hit” increases.
- the pitching result is calculated to be a “swing-and-miss” or “ball”.
- the ball speed calculation module 143 calculates a ball speed based on the information confirmed in the sensor 250 .
- the ball speed may be calculated so that to which one of the 5 groups (i.e., 30 km/h or below, between 30 km/h and 50 km/h, between 50 km/h and 70 km/h, between 70 km/h and 85 km/h, 85 km/h or above) the ball speed belongs to may be determined.
- the pitching result calculation module 140 calculates a pitching result according to the second method preset using calculated ball speeds.
- the probability that the pitching result will be a “strike” decreases while the probability that the pitching result will be a “hit” increases.
- the pitching result is calculated to be a “swing-and-miss” or “ball”.
- the batter level is the one already stored in the player database 190 and it may be classified into, for example, a high level, an intermediate level, and a low level.
- the batter level calculation module 141 confirms the batter level.

Abstract
Description
- The present invention relates to a method for playing screen baseball, and more specifically, to a method for playing screen baseball which can be progressed in a manner similar to real baseball while using a pitching mode.
- As used herein, the term “screen baseball” refers to a baseball game which can be played in a manner similar to a real baseball game using a screen, on which images are being projected, and a device such as a pitching machine, a toss machine, etc., by a user who watches the images of the game being projected on the screen.
- With regard to the screen baseball, the general mode is a “batting mode”, in which a baseball game is played according to the baseball rules such that a user becomes a batter, and as the user hits the ball discharged from a pitching machine the batting result, whether it is a hit or not, is determined and this whole process is repeated.
- Specifically, there is a screen hole in the center of the screen on which images are to be projected. Once a ball is discharged from a pitching machine located on the opposite side of the screen, the user hits the ball toward the screen direction and the batting result, whether it is a hit or not, is calculated by various sensors using the trajectory of the batted ball, etc.
- Alternatively, a “pitching mode” in which the user becomes a pitcher to play the game is also possible.
- Generally, when a user pitches a ball toward the screen, on which images are being projected, the batting result, whether it was a strike or ball, is calculated depending on the position where the ball touches on the screen (hereinafter, “catching position”).
- The related prior art technologies are described below.
- KR 1999-0046008A discloses a virtual reality pitching system in which virtual divided strike zones are established.
- JP 2006-181335A discloses a baseball game, in which the images of catchers performing catching motions according to the positions of the balls being pitched and the images of batters batting the balls are assigned, and the positions of the pitched balls are determined for each area, and batters' batting results are constituted as a result thereof.
- KR 2015-0109614A discloses a baseball game, in which the pitching result, whether the pitched ball was a strike or ball, is determined based on the XY coordinates of a pitched ball and then converted into a score, and thereby the result is derived.
- These prior art technologies commonly use only a strike zone.
- That is, once a strike zone is projected on a screen, the user as a pitcher throws a ball toward the strike zone and the game starts only based on whether or not the thrown ball has reached the strike zone.
- The above method for playing a game is only a target exercise like archery and shooting, and it can hardly be considered as real screen baseball. The method only enables determining of strikes/balls or playing of the game simply by calculating the scores according to the level of closeness inside the strike zone, as in archery. Whether it was a hit or not may be determined in some cases, but they are irrelevant with regard to whether a pitcher, who was the user, performed an appropriate pitch according to the baseball rules, because random probability is used in most cases.
- Since the method of playing the screen baseball in a pitching mode according to the conventional technology simply resorts to a repeated pitching toward a strike zone, which is the same immobilized target, users who play the screen baseball so as to enjoy a baseball game will be very bored.
- Furthermore, the method is played in a mode totally different from that of a real baseball game. The play mode is similar to that of archery, shooting, and darts.
- For example, a hit probability that may vary according to the ball speed even when balls were pitched to the same course, a hit probability when balls were pitched outside the strike zone (certainly, the hit probability must be calculated to be lower than the strike probability), a hit probability that increases when high-level batters appear, etc., cannot be considered.

- The present invention has been made to solve the above problems.
- Specifically, the present invention provides a method for playing screen baseball which can be progressed in a manner similar to a real baseball game according to the real baseball rules, while using a pitching mode.
- To solve the above problems, the present invention provides a method for playing screen baseball using a pitching mode, including:
-
- (a) setting a mitt
zone 10 by a mittzone setting module 130; - (b) projecting a
preset strike zone 20 and themitt zone 10 set in step (a) onto ascreen 300 by ascreen image unit 220; - (c) calculating a catching position based on the information confirmed in a
sensor 250 by a catchingposition calculation module 142; - (d) calculating a pitching result according to a first method, which was preset using the correlation between the
mitt zone 10 set in step (a) and the catching position calculated in step (c), by a pitchingresult calculation module 140; and - (e) playing screen baseball according to the baseball rules by a
game operation module 120, by repeating steps (a) to (d) for each pitch of a pitcher, - wherein the first method preset in step (d) is to calculate in such a manner that as the catching position calculated in step (c) becomes farther from the center of the
mitt zone 10, the probability of a pitching result being a “strike” decreases while the probability of a pitching result being a “hit” increases.
- (a) setting a mitt
- Additionally, preferably, step (c) further includes (c1) calculating a ball speed based on the information confirmed in the
sensor 250 by a ballspeed calculation module 143; and step (d) further includes (d1) calculating a pitching result according to a second method, which was preset using the ball speed calculated in step (c1), by the pitchingresult calculation module 140, wherein the second method preset in step (d1) is to calculate in such a manner that as the ball speed calculated in step (c1) decreases, the probability of a pitching result being a “strike” decreases while the probability of a pitching result being a “hit” increases. - Additionally, preferably, step (b) further includes projecting the information on batters, which was loaded in a
player database 190, onto thescreen 300 by thescreen image unit 220. - Additionally, preferably, step (c) further includes (c3) confirming a batter level from the loaded information on batters by a batter
level calculation module 141; and step (d) further includes (d3) calculating a pitching result according to a third method, which was preset using the confirmed batter levels calculated in step (c3), by the pitchingresult calculation module 140, wherein the third method preset in step (d3) is to calculate in such a manner that as the batter level confirmed in step (c3) becomes higher, the probability of a pitching result being a “strike” decreases while the probability of a pitching result being a “hit” increases. - Additionally, preferably, step (d) calculates the pitching result by adding up a first value calculated according to the correlation between the
mitt zone 10 set in step (a) and the catching position calculated in step (c), a second value using the ball speed calculated in step (c1), and a third value using the confirmed batter level calculated in step (c3), by the pitchingresult calculation module 140, wherein as the sum of the added-up values increases, the probability of a pitching result being a “strike” decreases while the probability of a pitching result being a “hit” increases, and wherein the first value increases as the calculated catching position becomes farther from the center of themitt zone 10, the second value increases as the ball speed becomes lower, and the third value increases as the batter level becomes higher. - Additionally, preferably, in step (a), the
mitt zone 10 is set in such a manner that the center of themitt zone 10 is positioned inside thestrike zone 20 by the mittzone setting module 130. - Additionally, preferably, when the catching position calculated in step (c) is outside the
strike zone 20, the pitching result is calculated to be a “swing-and-miss” or “ball” by the pitchingresult calculation module 140 in step (d). - Additionally, preferably, after step (b) and before step (c), the
game operation module 120 transmits a signal so that atoss machine 230 tosses a ball when a discharge signal is approved in adischarge signal device 210. - Additionally, preferably, after step (e), the method for playing screen baseball further includes: (f) projecting an event image onto the
screen 300 by thescreen image unit 220 when the event image is approved by anevent execution module 150; (g) transmitting a signal by thegame operation module 120 so that thetoss machine 230 tosses a ball when a discharge signal is approved in thedischarge signal device 210; (h) calculating a catching position by the catchingposition calculation module 142 based on the information confirmed in thesensor 250; and (i) calculating the event result preset corresponding to the calculated catching position by theevent execution module 150, and projecting an event image corresponding to the calculated event result onto thescreen 300 by thescreen image unit 220. - According to the present invention, a user can enjoy a screen baseball in a manner similar to that of a real baseball.
- In particular, pitching results can be calculated using only a catching position, or using both a catching position and a ball speed, or using a catching position and a ball speed in combination with a batter level, and thus the screen baseball game can be played in a manner similar to that of a real baseball game and thus increase the user's sense of immersion and interest.
- For example, similarly as in real baseball, the hit probability increases when a pitcher fails to throw a ball to the position requested by a catcher, when the ball speed becomes lower, and when it is assumed that a good batter appears on the batter's box.
- Additionally, an event may be performed in some cases, and the event may be performed without additional facility by using the catching position confirmation system which is already established.

FIG. 3 shows diagrams illustrating a mitt zone with regard to a method for playing screen baseball according to the present invention. -
FIGS. 4 to 6 show exemplary images being projected on a screen with regard to a method for playing screen baseball according to the present invention, in whichFIG. 4 shows a general image before setting a mitt zone,FIG. 5 shows an image after setting a mitt zone, andFIG. 6 shows an image while executing an event. -
FIG. 7 shows a flowchart illustrating the method for playing screen baseball according to the present invention. - As used herein, the term “catching position” refers to the position where the ball thrown by a pitcher, who is a user, toward the screen reaches and can be confirmed by various sensors.
- As used herein, the term “ball speed” refers to the speed of the ball thrown by a pitcher, who is a user, toward the screen and can also be confirmed by various sensors.
- As used herein, the term “pitching result” refers to the result of a batting or the result of a swing-and-miss by a virtual batter according to the baseball rules after a ball is thrown toward the screen by a pitcher, who is a user. In a case where the calculation was made assuming that the virtual batter failed to perform a batting, the result would be calculated as either of a “strike” or “ball”, whereas in a case where the calculation was made assuming that the virtual batter performed a batting, the result would be calculated as either of a “swing-and-miss” or “hit”. In particular, the “hit” may be more precisely calculated, e.g., a “one-base hit”, an “extra-base hit”, etc.
- Hereinafter, the present invention will be explained in more detail with reference to accompanying drawings.
-
FIG. 1 shows a screen baseball field in which the method for playing screen baseball according to the present invention is achieved. - A terminal 100 for manipulating the game mode operated by a user or operator is located in a safe area separated by a
safety fence 102. The terminal 100 may also possibly be located within the operation area outside the screen baseball field. - The user can enter the game area through a
gate 103 of thesafety fence 102. - The screen baseball field includes a
screen 300, onto which the images are being projected; adischarge signal device 210, which is in the form of a pedal, for transmitting signals for playing a game; ascreen image unit 220 for providing images; and asensor 250 for detecting ball speeds and catching positions. - A
toss machine 230 for tossing balls to a user is located in the screen baseball field (not shown inFIG. 1 ). In particular, thetoss machine 230 delivers balls to a user after one or two bounds and thus the screen baseball can be played safely. Thetoss machine 230 may be any device capable of tossing balls to a user and may be freely selected from various conventional toss machines, and thus detailed explanation will be omitted herein. - The
sensor 250 may be any sensor as long as it can detect ball speeds and catching positions. - Once entering the game area, the user can play the game while watching the images being projected onto the
screen 300. Upon stepping on thedischarge signal device 210, a ball is tossed to the user from thetoss machine 230, and the user catches the ball and pitches toward thescreen 300. In particular, ball speeds and catching positions are calculated by thesensor 250, etc. - The balls are dropped into the bottom thereof upon reaching the
screen 300 and collected manually or automatically by abaseball collecting unit 205 and returned. - Hereinafter, the information flow will be explained referring to
FIG. 2 . - The terminal 100 may include a
game setting module 110, agame operation module 120, a mittzone setting module 130, a pitchingresult calculation module 140, and anevent execution module 150. - The user may set the game mode by the
game setting module 110. - For example, any one game may be selected from the group of games consisting of a 1:1 game, a 1:1:1 game, a single game, etc., which are preset in various modes.
- The
game operation module 120 performs overall functions with regard to game operation. Specifically, thegame operation module 120 loads information of players on aplayer database 190 and controls thedischarge signal device 210,screen image unit 220,toss machine 230, etc. - The mitt
zone setting module 130 sets a mitt zone according to the predetermined method so that the mitt zone can be projected through thescreen image unit 220. Themitt zone 10 is the core concept of the present invention and will be described herein below. - The pitching
result calculation module 140 calculates a pitching result, which is the result after the user's pitching, and the pitching result may be any one selected from a “strike”, a “ball”, a “swing-and-miss”, and a “hit”. The pitchingresult calculation module 140 calculates the pitching result based on the batter level confirmed by the batterlevel calculation module 141, the catching position confirmed by the catchingposition calculation module 142, and the ball speed confirmed by the ballspeed calculation module 143. The details of the calculation method will be described later. - The
event execution module 150 performs an event when a particular condition is met. In a case where an event is performed, the baseball being played is temporarily stopped and an image as shown inFIG. 6 is projected onto thescreen 300, in which as the user throws a ball toward thescreen 300, the catching position is confirmed by the catchingposition calculation module 142, thereby confirming the event result. - The mitt zone according to the present invention will be explained referring to
FIG. 3 . - For playing baseball by simulating the real baseball rules, the present invention uses two different areas, i.e., a
strike zone 20 and amitt zone 10. - The
strike zone 20 means the strike zone in a real baseball game. For example, thestrike zone 20 may be in the shape of a square (left: 78 cm, right: 78 cm), but it can surely be adjusted according to other factors such as degree of difficulty of the preset game, batters, etc. It must be noted that thestrike zone 20 is projected to an area which is fixed on thescreen 300. - The
mitt zone 10 is the area within which a catcher can catch balls. In other words, themitt zone 10 refers to the area where the catcher's mitt is located. - Preferably, the
mitt zone 10 is in the shape of a circle. Also preferably, themitt zone 10 is projected so that the catcher's mitt can be located in the center of themitt zone 10 on the image being projected on the screen 300 (seeFIG. 5 ). - In a case where the catching position of a ball thrown by a pitcher, who is the user, is the center of the
mitt zone 10, it means that the ball was accurately thrown according to the catcher's sign in real baseball. Accordingly, the probability that the pitching result will be a “strike” is high while the probability that the pitching result will be a “hit” is low. - In contrast, if the catching position of a ball thrown by a pitcher, who is the user, is located farther from the center of the
mitt zone 10, it means that the ball was thrown against the catcher's sign in real baseball. Accordingly, the probability that the pitching result will be a “strike” is low while the probability that the pitching result will be a “hit” is high. - For the improvement of the calculation, the
mitt zone 10 may be further divided into afirst area 11 in the center, asecond area 12 which is an intermediate area, and a third area on theexternal side 13. - When the catching position calculated by the catching
position calculation module 142 is in thefirst area 11, the probability that the pitching result will be a “strike” becomes highest. - When the catching position calculated by the catching
position calculation module 142 is in thesecond area 12, the probability that the pitching result will be a “hit” is high, and if it is in thethird area 13, the probability that the pitching result will be a “hit” is highest. - In a case where the calculation is performed by dividing hits into “one-base hits” and “extra-base hits”, when the catching position is in the
second area 12, the hit may be calculated as a “one-base hit”, whereas when the catching position is in thethird area 13, the hit may be calculated as an “extra-base hit”. - That is, as the catching position calculated by the catching
position calculation module 142 moves from thefirst area 11 to thethird area 13, the pitch will correspond to a careless pitch that moves away from the preset sign between the user, who is the pitcher, and the catcher (i.e., the first area 11), and thus the hit probability (e.g., a one-base hit, an extra-base hit, a home run, etc.) will increase. - As shown in
FIG. 3 (a) to (d) , it is preferred to change themitt zone 10 whenever the user makes a pitch. This can further increase the interest of the user and the user can play the screen baseball in a manner close to real baseball without throwing balls toward the very center of thestrike zone 20, thereby further increasing the user's sense of immersion compared to the conventional technology. - Although the
mitt zone 10 may be changed randomly, it may be changed into a course, which may act as the Achilles heel for the corresponding batter, based on the information of batters stored in theplayer database 190. For example, in a case where the virtual batter on the batter's box is confirmed to be one who can deal with high balls very well based on the information stored in theplayer database 190, themitt zone 10 may be set to a lower area. As such, the user can be more deeply immersed in the screen baseball. - Meanwhile, the center of the
mitt zone 10 is preferred to be located inside thestrike zone 20. Certainly, it is possible that a catcher may request that a pitcher throw balls other than a strike in real baseball, but it is preferred to induce only strikes considering the characteristics of screen baseball which needs a speedy process. - The method for playing screen baseball according to the present invention will be explained in detail referring to
FIGS. 4 to 7 . - First, a game desired by a user can be set by the
game setting module 110, and the game starts by agame operation module 120. - Then, the
mitt zone 10 is set by the mittzone setting module 130. Themitt zone 10 may be set randomly as described above or set based on the information of batters stored in theplayer database 190. - Then, the
screen image unit 220 projects themitt zone 10 and thestrike zone 20 together onto thescreen 300, and the information of batters that can be confirmed in the player database 190 (various kinds of information including images of batters, statistical data, etc.) is projected further thereonto, and thereby the pitcher, who is the user, is now ready to pitch a ball (FIGS. 4 and 5 ). - Now, the
screen image unit 220 outputs an image through thescreen 300, which requests the user to operate thedischarge signal device 210. - Once the user operates the discharge signal device 210 (e.g., by stepping on the pedal) to approve the signal, the
toss machine 230 tosses a ball to the user. The user catches the tossed ball and pitches toward the center of themitt zone 10, which is projected onto thescreen 300. Thesensor 250 detects information necessary for the calculation of ball speeds and catching positions. - According to an exemplary embodiment of the present invention, the pitching result may be calculated based on only a catching position, or based on both a catching position and a ball speed, or based on a catching position, a ball speed, and a batter level.
- First, the case where the pitching result is calculated based on the catching position will be described.
- The catching
position calculation module 142 calculates a catching position based on the information confirmed in thesensor 250. That is, the distance of the catching position from the center of themitt zone 10 is calculated, and also whether the catching position is inside thestrike zone 20 can be calculated together. In another exemplary embodiment of the present invention, whether the catching position is within thefirst area 11, thesecond area 12, and thethird area 13, which are explained inFIG. 3 , can be calculated. - The pitching
result calculation module 140 calculates a pitching result according to the first method preset using the correlation between themitt zone 10 and the catching position. In particular, according to the first method, in a case where the catching position is within thestrike zone 20, as the catching position becomes farther from the center of themitt zone 10, the probability that the pitching result will be a “strike” decreases while the probability that the pitching result will be a “hit” increases. In a case where the catching position is outside thestrike zone 20, the pitching result is calculated to be a “swing-and-miss” or “ball”. - Then, the case where the pitching result is calculated using a ball speed in addition to the catching position will be described.
- The ball
speed calculation module 143 calculates a ball speed based on the information confirmed in thesensor 250. For example, the ball speed may be calculated so that to which one of the 5 groups (i.e., 30 km/h or below, between 30 km/h and 50 km/h, between 50 km/h and 70 km/h, between 70 km/h and 85 km/h, 85 km/h or above) the ball speed belongs to may be determined. - The pitching
result calculation module 140 calculates a pitching result according to the second method preset using calculated ball speeds. In particular, according to the second method, as the ball speed decreases, the probability that the pitching result will be a “strike” decreases while the probability that the pitching result will be a “hit” increases. In a case where the catching position is outside thestrike zone 20, similarly as in the first method, the pitching result is calculated to be a “swing-and-miss” or “ball”. - Then, the case where the pitching result is calculated using a batter level in addition to the catching position and ball speed will be described.
- The batter level is the one already stored in the
player database 190 and it may be classified into, for example, a high level, an intermediate level, and a low level. - The batter
level calculation module 141 confirms the batter level. - The pitching
result calculation module 140 calculates a pitching result according to the third method preset using batter levels. In particular, according to the third method, as the batter level increases, the probability that the pitching result will be a “strike” decreases while the probability that the pitching result will be a “hit” increases. In a case where the catching position is outside thestrike zone 20, the pitching result, while being calculated as a “swing-and-miss” or “ball”, is calculated in such a manner that as the batter level increases, the probability that the pitching result will be a “ball” increases while the probability that the pitching result will be a “swing-and-miss” decreases. - In particular, in a case where the information of all three of the catching position, ball speed, and batter level is utilized, the pitching result may be calculated as described below.
- The pitching
result calculation module 140 calculates a pitching result by adding up the first value according to the correlation between themitt zone 10 and the catching position, the second value using a ball speed, and the third value using the batter level. The first value increases as the calculated catching position becomes farther from the center of themitt zone 10, the second value increases as the ball speed decreases, and the third value increases as the batter level becomes higher. As the added-up value increases, the probability that the pitching result will be a “strike” decreases while the probability that the pitching result will be a “hit” increases. - As such, the method for calculating the pitching result is repeated for each pitching of the pitcher. For each pitching, pitching results such as a “strike”, a “hit” (in some cases, a “one-base hit” and an “extra-base hit”, a “swing-and-miss” (in this case, the pitching result is calculated as a “strike”), and a “ball” are calculated. Based on the above, the
game operation module 120 causes the screen baseball to proceed in a similar manner as in real baseball according to the baseball rules. - Meanwhile, the level of interest may be enhanced by additionally generating an event.
- In a case where an event execution signal is approved by the
event execution module 150, thescreen image unit 220 projects the event image onto thescreen 300. - The
screen image unit 220 outputs an image through thescreen 300 requesting that the user operate the discharge signal device 210 (FIG. 6 ). - When the user approves a discharge signal by operating the
discharge signal device 210, thetoss machine 230 tosses a ball to the user, and the user catches the tossed ball and pitches the ball toward the center of themitt zone 10 projected onto thescreen 300. - Once the ball is pitched, the catching
position calculation module 142 calculates the catching position based on the information confirmed in thesensor 250. - The
event execution module 150 calculates the result of the event preset corresponding to the calculated catching position and thescreen image unit 220 projects the image corresponding to the calculated event result onto thescreen 300. - Although preferred embodiments of the present invention have been described in detail herein, it is to be understood that other modifications and variations may be effected by one of ordinary skill in the art without departing from the spirit and scope of the invention as defined by the appended claims. Furthermore, in a case where at least one embodiment among the various embodiments is combined, it should also belong to the scope of the present invention.
