Description

The present invention relates to a game piece and a board game used in a game match.

In order to solve the above problem, in the invention according to claim 1, in a board game composed of a game board and a plurality of pieces, the pieces are provided with RFID tags indicating the position information of the pieces, and the game board is a board. individual recognizable R F I D antenna where to place該駒above with built one by two front and rear each cell, different to both the front and back該駒to determine the front and back of該駒on the board front and back A discrimination RFID tag is built-in, the front and back discrimination RF ID tags are electromagnetically shielded, and different direction discrimination RFID tags are built in both front and back of the front and back respectively. The game board has an electromagnetic shield between the RFID tags for direction determination, a front and back and direction determination function, and a position instruction function for each piece on the board, and the position instruction function is displayed on the game board. It provides an on-board game characterized by being.

Further, in Patent Document 2, an RFID tag or the like is created in a piece to recognize the position and type of the piece, a sensor for reading the piece is provided, and a piece in which such an RFID or the like is embedded is used for a battle. By recognizing the type and position of the RFID tag, etc., each move that is moved, placed, or removed by both parties, the game is recognized and the image displayed on the board is changed based on the recognition. It describes an intelligent game system that can be used, a game piece, a method of projecting a changed image, a method of acquiring object information, and a method of playing an intelligent game.

However, in such a game system or the like, both players need to be humans, and if there is only one human being, the use is limited to a study game that also serves as both players. Further, in such a game system or the like, in the case of one type of piece, only one type of state can be recognized. Therefore, in a game such as Japanese chess where both front and back states are possible, in such a game system, it is necessary to arrange pieces for each state, and the types of pieces increase, which makes it complicated and troublesome to handle. There was a problem.

JP 2011-130973 JP 2015-09615

Even when a plurality of states such as front and back can be recognized as the state of a piece, there has been a demand for a game system or the like that can recognize not only the position of the piece but also the front and back on the board as in a non-electronic game.

For example, if there is only one RFID tag built-in in a board game such as Othello (registered trademark) that is played upside down, the front and back of the piece will be from only the RFID tag. Could not be determined and had to be used in combination with other means such as image acquisition.

In addition, in the case of something like a shogi piece, it is not enough to judge the position of the piece on the board and the front and back of the piece, and the direction of such a piece also has meaning. That is, the side of the piece facing the pointed direction points to the enemy side of the piece. That is, it means that the horizontal base side is a piece of one's own team. Therefore, if the pieces are turned in the opposite direction, the enemy pieces and the viewpoint pieces are exchanged. However, when there is only one RFID tag, it cannot be determined from the RFID tag alone whether the piece is the piece of the viewpoint or the piece of the opponent.

In order to solve the above problem, in the invention according to claim 1, in a board game composed of a game board and a plurality of pieces, the pieces are provided with RFID tags indicating the position information of the pieces, and the game board is individually mounted on the board. In addition to incorporating two front and rear RFID antennas in each box that can recognize the placement location of the piece, there are different front and back RFID tags on both the front and back of the piece in order to distinguish the front and back of the piece on the board. Built-in, the front and back RFID tags for front and back discrimination are electromagnetically shielded, and different direction discrimination RFID tags are built in both front and back of the front and back, respectively, and the direction discrimination RFID tags are electromagnetically shielded. A board game having a front / back and direction determination function provided with a shield, and a position indicating function of each piece on the board, and the position indicating function is a display display on the game board. Is to provide.

Further, the invention according to claim 2 provides the board game according to claim 1, wherein the opponent's piece can be displayed on the game board.

Further, in the invention according to claim 3, the game board has a reflectance measuring function of each piece for each arrangement place on the board, and the pieces have different reflectances on the front and back, so that the front and back discrimination function is provided. The on-board game according to claim 1 or 2, wherein the reflectance measuring function is performed by measuring the reflectance of each piece.

Further, in the invention according to claim 4, the board game according to claim 1 or 2 is provided in which the front / back discrimination function of the piece is performed by reading the RFID tag for front / back discrimination of the piece on the game board. be.

Further, in the invention according to claim 5, the game board has a communication function, and the communication function transmits and receives the movement of each piece of the game board and the movement of each piece of the opponent. The board game according to claim 2 is provided.

The invention according to claim 6 provides the board game according to claim 2 or 5 , wherein the opponent is a computer program or artificial intelligence.

According to the present invention, it is possible to stably determine not only the position of each piece on the board, which was difficult in the past, but also the state of the piece, for example, the front and back or the direction of the piece, thereby completely determining the state of the piece. It has become possible to play as a more realistic board game regardless of whether the opponent is a human or a computer match.

It is a conceptual block diagram of the game board used for the board game which concerns on this invention. Unlike FIG. 13, which is used in the board game according to the present invention, it is a schematic plan view showing a state in which only oneself is placed on the game board and the opponent's piece is displayed on the game board.

Hereinafter, the embodiment of the present invention will be described with reference to the drawings in the case where the board game is shogi.

FIG. 1 is a game board 1 used in the board game according to the present invention. The game board 1 is composed of a large number of boxes 11 on which pieces actually work and a piece stand 12 on which the pieces on hand are placed, and the large number of boxes 11 and the piece stand 12 are the places where the pieces are arranged.

Shogi pieces include kings, gold generals, silver generals, lancers, lancers, pawns, rooks, and bishop pieces. To explain the example of a rook, the surface 21 of the piece is described as a rook. On the back surface 22 of the piece, it is described as a dragon king as shown in FIG.

(Piece)
Whether the piece is front or back has a big meaning on the game board, and there is a big difference in the function and value of the piece. In addition, the orientation of the pieces also has a great meaning, and for those who point to shogi, it means that the piece whose tip is facing the enemy side as shown in Fig. 2 is a ally piece, and the tip of the piece is as shown in Fig. 4. On the contrary, a piece facing the ally side means that it is an enemy piece.

Each piece placed on the board of this piece has a built-in RFID tag whose recognition information differs depending on the type of the piece. In this example, two RFID tags are embedded for identification of the front and back of the piece. It constitutes a front-back discrimination function. That is, the front side RFID tag 211 of the piece is embedded in the front surface 21 of each piece placed on the board as shown in FIG. 5, and the back side RFID tag 212 of the piece is embedded in the back side 22 of the piece as shown in FIG. ..

The recognition information includes information for identifying the piece, such as information indicating what kind of piece the piece is, unique identification information if the piece is of the same type, and information indicating the front and back of the piece.

Then, in order to prevent both RFIDs from working at the same time, an electromagnetic wave shield 23 is provided between the RFID tag 211 on the front side of the piece and the RFID tag 212 on the back side of the piece, whereby the electromagnetic field is shielded. As a result, when the piece is placed in a specific box with the front side facing up, only the RFID tag 212 on the back side of the piece works, and when the piece is placed in a specific box with the back side facing up, the RFID tag on the front side of the piece is placed. Only tag 211 will work.

Furthermore, if you want to determine whether an individual piece placed on the board is an enemy piece or an ally piece using only the RFID tag, you must determine the orientation of each piece placed on the board. For example, a method such as embedding an RFID tag both in the front and the rear can be considered.

For example, in order to recognize the front and back of each piece placed on the board and its direction at the same time, two RFID tags, one on the front and one on the back, may be embedded on both the front and back sides.

Specifically, as shown in FIG. 9, the front side front RFID tag 214 of the piece is in front of the surface 21 of each piece placed on the board, and the front side rear RFID tag 215 of the piece is behind the surface 21 of the piece, as shown in FIG. A front RFID tag 224 on the back side of the piece is embedded in front of the back surface 22 of the piece, and an RFID tag 225 on the back side of the back side of the piece is embedded behind the back surface 22 of the piece. In order to prevent both the front and back RFIDs from working at the same time, an electromagnetic wave shield 23 is provided between the front front RFID tag 214 of the piece, the front rear RFID tag 215 of the piece, the back front RFID tag 224 of the piece, and the back rear RFID tag 225 of the piece. Has been done.

Then, in order to prevent both the front and rear RFIDs from working at the same time, the front front RFID tag 214 of each piece and the back front RFID tag 224 of the piece, and the front rear RFID tag 215 of the piece and the back rear of the piece are placed on the board. An electromagnetic wave shield 24 is provided between the RFID tag 225 and the RFID tag 225.

(Game board)
The game board 1 is provided with a display device so that, for example, as shown in FIG. 14, each box or piece stand can display a movement source display 42, a movement destination display 43, a movement prompting display 44, and the like. Further, as shown in FIG. 15, two front and rear RFID antennas 51 may be provided in each box, and the piece stand 12 may also be provided with RFID antennas 52.

Further, when the game board 1 is conceptually viewed from the side, a display device 61 is provided on the surface of the box as shown in FIG. 16, and one RFID antenna for each box or two RFID antennas for the front and the rear are below the display device 61. 62 is provided, and the signal transmitted and received by the RFID antenna is processed by the RFID reader 63. The display device 61 displays an image of each piece, information on the state of each piece, prompts the movement of each piece on the board, displays a holding piece, and the like. At this time, the display device 61 may be provided for each box, but it may be a display that has one side as a whole and the display of the area corresponding to each box can be freely changed. When using not only the individual pieces placed on the board but also the pieces on the piece stand 12 for the game, it is necessary to be able to display them on the piece stand 12.

Further, the display device may be an LED, an organic EL, or the like in addition to the liquid crystal display device, and the type thereof does not matter.

(Function of RFID tag)
Here, assuming a state in which the RFID antenna is provided only on the enemy side of the box, when an ally piece is placed on a specific box with the surface facing up as shown in FIG. 9, the front RFID on the back side of the piece is placed. When the tag 224 works and the enemy piece is placed on a specific box with the front side facing up as shown in FIG. 11, the RFID tag 225 behind the piece works and the back side is turned up on the specific box as shown in FIG. When a friendly piece is placed, the front-side front RFID tag 214 of the piece works, and when an enemy piece is placed face up in a specific box, the front-side rear RFID tag 215 of the piece works.

When actually playing a game, pieces 31 on the game board and pieces 32 on the piece stand of many types and states are used by using individual pieces placed on the board on the game board 1 as shown in FIG. Is used.

(Data processing unit)
The data processing in such a game board 1 is performed by the configuration as shown in the block diagram as shown in FIG. That is, the bus line includes an RFID reader 801, a display device drive device 803, a CPU 805, a memory 806, and a communication device 807.

The RFID reader 801 is connected to the RFID antenna 802 and can receive a signal from the RFID tag for determination. In this case, the RFID reader 801 is essential to be able to receive a signal from the RFID tag, but it can also be configured to transmit a signal to the RFID tag.

The display device drive device 803 controls the display of the image of each piece, information on the state of each piece, prompting the movement of each piece on the board, displaying the possessed piece, and the like on the display device 61 already described. It is a thing. The display method in this case can be appropriately selected according to the rules. Of course, it may be an integral structure with the RFID antenna 801.

The CPU 805 processes macro flows, which will be described later, and various information such as communication.

The memory 806 is composed of a ROM, a RAM, a hard disk, or other information storage device, and for example, stores the rules of this game, or positions both individual pieces other than the board and individual pieces on the board. In addition to memorizing the state, it is also possible to memorize the software of the artificial intelligence to play against. Further, the game stored here may be not only a single type of game but also a game equipped with a plurality of types of game software.

(Movement of pieces)
Here, the macro flow for determining the state such as the movement of the pieces on the board will be described below. Of course, the macro flow for judging the state of the pieces on the board is not limited to the following judgment flow, and if it can realize the judgment of the state of the same piece, it is of another type. Macro flow is also acceptable.

First, it is premised that the game board always communicates with individual pieces on the board and receives the signal periodically. Therefore, by not detecting the RFID tag in some box (701), it is detected that there is some change in the situation on the board.

Then, it is determined whether or not the RFID tag is not detected in yet another box (702). If the determination is YES, it is determined that the piece has been taken by the opponent, and the process proceeds to process 703. On the other hand, if the determination is NO, it is determined that the piece was not taken by the opponent, and the process proceeds to process 707.

In the process 703, it is determined whether or not the RFID tag is detected in either of the boxes, and if YES, it is determined that the start is completed, and the process proceeds to the process 710. On the other hand, in the case of NO, the operation proceeds to detect the RFID tag in yet another box (704). If the process 704 is YES, it is determined that there is an abnormality, and the process proceeds to the process 706 for displaying a warning. On the other hand, in the case of NO, it is determined that the start has not been completed yet, and the start is awaited (705). If a certain period of time has passed while waiting for the start, the process proceeds to process 706 for displaying a warning. After the process 706, the process returns to the process 703 for determining whether or not the RFID tag is detected in either of the boxes.

If NO is determined in the process 702, the process proceeds to the process 707 of detecting the RFID tag in some box. If YES, it is determined that the start has been completed, and the process proceeds to process 710. On the other hand, in the case of NO, it is determined that the start has not been completed yet, and the start is awaited (708). If a certain period of time has passed while waiting for the start, the process proceeds to process 709 for displaying a warning. After the process 707, the process returns to the process 707 for determining whether or not the RFID tag is detected in either of the boxes.

If YES in the above processes 703 and 707, it is tentatively determined that the start has been completed, and the process proceeds to the process 710 for detecting the recognition information of the RFID tag. Then, the game rule such as a database is referred to, and the rule is referred to to determine whether the movement of the piece is correct (711).

As a result of the process 711, if it is determined that the movement of the piece is correct according to the rules and it is determined to be YES, a process of storing the newly moved position is performed (712), and the process related to this start is terminated (713). On the other hand, if it is determined that the rule does not conform to (NO), the process proceeds to the process of displaying a warning 709, and the process proceeds to the process 707 of determining whether or not the RFID tag is detected in either box.

In this case, if it is determined that the rule is not met and (NO) is determined, a process of losing the foul may be performed instead of proceeding to the process of displaying the warning 709. Further, even when a warning is displayed (706, 709) after a certain period of time has elapsed, a process of losing the foul may be performed.

The above macro flow example is for games where pieces move, such as shogi, chess, and Chinese shogi, but on the other hand, it is generally different for games that add pieces such as Othello (registered trademark) and Go. It may be a macro flow or a process that just grasps the position as it is.

(Competition between humans)
Hereinafter, a case where humans play against each other will be described. When fighting while facing each other directly across the same game board, two people play against each other using pieces in the same way as in a normal game. In this case, by playing against each other using an actual piece, it is possible to automatically record the movement of the piece and leave it as a game record, which can be reproduced later.

When reproducing the movement of the piece, the image of the piece may be simply displayed on the display device 61 on the game board to reproduce and display the movement of the piece, but the movement source is displayed using the actual piece as shown in FIG. By moving the moving piece 41 in 42 to the box where the destination display 43 is located according to the display urging display 44, it is possible to reproduce the situation closer to the actual battle environment, and it is closer to the time of the battle. You can reexamine the result of the match with a sense.

(Competition between humans via communication)
Next, the case of competing via communication will be described. In this case, two opponents, A and B, who are distant opponents, each prepare the board game of the present application, and the two game boards have a communication device 807 as shown in the figure, and the Internet. It is necessary to enter the communication state via the line. Then, when the instep moves an individual piece on the board, the instep game board recognizes the movement of the piece and its front and back, and sends the information corresponding to the recognition to the second game board. In this case, instead of the movement of each piece on the board, the position of each piece on the board after movement and the front and back thereof may be transmitted.

On the game board of the second party having the function of receiving the information, the display 42 of the moving source that moved the piece of the instep, the display 43 of the moving destination, the display 44 prompting the movement, and the like are displayed. According to the display, B reproduces the movement of each piece on the board of the instep.

Next, when B moves an individual piece on the board, the game board of B recognizes the movement of that piece and its front and back, and sends information corresponding to that recognition to the game board of A. Upon receiving the information, the game board of the instep displays the display 42 of the movement source in which the individual pieces on the board of the second are moved, the display 43 of the movement destination, the display 44 for prompting the movement, and the like. According to the display, the instep reproduces the movement of each piece on the board of the second party. In this way, it is possible to play in a situation close to the actual face-to-face battle environment, and to play a battle with a feeling closer to that of a face-to-face battle.

(Competition with artificial intelligence)
Next, the case of playing against a computer program such as artificial intelligence or shogi software will be described. In this case, the shogi software may be built into the game board from the beginning, but the program may be downloaded from a server or the like via an internet line, or the program processing on the cloud or computer may be received at any time via the internet line. By various means, it is possible to use a wide variety of the latest artificial intelligence and shogi software. Artificial intelligence here has rules such as shogi as learning material, and establishes a method for winning by repeating battles by self-learning.

When an opponent moves an individual piece on the board, the game board recognizes the movement of that piece, artificial intelligence and shogi software consider the next move based on the information corresponding to that recognition, and the game follows that move. The board displays a display 42 of the movement source in which the piece of the instep is moved, a display 43 of the movement destination, a display 44 prompting the movement, and the like. According to the display, the opponent moves not only the individual pieces on his board but also the individual pieces on the board on the artificial intelligence and shogi software side. In this way, it is possible to play in a situation close to the environment of a battle with a person, and it is possible to play a battle with a feeling closer to that of a face-to-face battle.

In this case, the display 44 for prompting the movement may be indicated by a means such as an animation display in which the moving source piece sequentially moves to the moving destination position, in addition to an arrow or the like. In addition, if there are pieces taken, in addition to the display prompting each piece on the board to move to the piece stand, it may be indicated by means such as an animation display in which the taken pieces move sequentially. ..

In addition, the act of becoming a so-called promotion piece, in which the piece with the front side changes to the back side, is indicated by means such as an animation display in which the front side is turned over, in addition to the one instructing the piece formation. It doesn't matter if it's something.

The display content may not be an instruction for the opponent to reproduce the movement of the artificial intelligence piece using the actual movement of the piece, but may display the position and state of the piece after the movement. In this case, for example, as shown in FIG. 20, both the piece on the board and the piece on the piece stand are real pieces 91, and the opponent's piece is a piece on the board and a piece on the piece stand. Both are pieces 92 displayed on the display. As a result, since one's own piece uses the real piece 91, a sense of reality can be obtained. On the other hand, since the opponent's piece is the piece 92 displayed on the display, there is an advantage that the trouble of moving the opponent's piece can be saved.

In this case, you may take the opponent's piece, but since the opponent's piece is not the actual piece but the piece displayed on the display, in this case, the actual piece placed separately is your own piece. It is necessary to replenish the table.

On the other hand, if your opponent's piece is taken by your opponent's piece, you need to put it in a separate place except for the actual piece taken from the board.

In the above example, an example is shown in which a large number of boxes and a piece stand are used as the placement location of each piece on the board that requires recognition, but it may be composed of only a large number of boxes. It is not inevitable to recognize the piece stand as long as the individual pieces on the board that cannot be recognized due to being removed from the box are automatically judged to be the pieces possessed by the enemy.

As described above, the case where the front / back determination function of each piece on the board is realized by the RFID tag, but the front / back determination function of the piece is not limited to this, and is realized by, for example, the reflectance measurement function by the image pickup device or the scanning function. It doesn't matter what you do. In this case, it is necessary that the reflectances of the pieces used in this board game are different on the front and back. However, it is not necessary for visible light to make the reflectance of each piece on this board different. That is, if the visibility of the user is deteriorated due to the difference in the reflectance at the visible light wavelength on the front and back, or if the visual sensation gives a sense of discomfort, the reflectance at a wavelength other than the visible light such as near ultraviolet rays is made different. It doesn't matter if it is due to something. Further, as a means for making the reflectance different, in addition to a method of devising the coloring of the surface, a method of making the surface reflectance different such as unevenness may be used.

It should be noted that the individual pieces on the board that require the front / back determination function may be applied only to pieces having different front / back movements and values by using both sides. That is, in the example of shogi, since the king and the gold general are used only on the surface in the game, it is not necessary to give the front and back judgment function of the pieces to those pieces.

Further, instead of such a reflectance measurement function, an image recognition function may be used to realize a front / back determination function of each piece on the board. That is, an image pickup device such as a camera may be provided in the information of the game board, and the type and front and back of each piece on the board may be determined by character recognition or the like based on the image pickup result. In this case, since the type of the piece is displayed in black on the front surface of the shogi and the type of the piece is displayed in red on the back surface, the front and back may be discriminated using it.

Similarly, it is not necessary to use an RFID tag to determine the orientation of each piece on the board, and the orientation of the pieces may be determined by the reflectance measurement function or the image recognition function as described above.

Further, magnets may be provided on both the game board and the individual pieces on the board. That is, a magnet or the like is used to steadily adhere to the game board to ensure that the RFID tag and the RFID antenna can communicate with each other, or to prevent the piece from moving unnecessarily from the game board for travel purposes. In some cases, it may be preferable that the contact can be easily made by the above means.

In this case, since the magnet has the property that the same poles repel, for example, when the game board has N poles, if the back side of the piece is the S pole, the pieces are in close contact with each other in the front side, but in that case, the front side of the piece is N. It becomes a pole, and when the back side is turned upside down, the N poles repel each other, so they cannot be in close contact with each other. To prevent this, place magnets on both the front and back of the piece with the same poles facing each other, or when the pieces are brought closer, the magnets on the game board will rotate so that the surface that attracts the pieces faces upward. Some kind of ingenuity is required.

The individual pieces on the board that require such ingenuity may be those that use both sides and are applied only to pieces with different front and back movements and values. In other words, in the example of shogi, the king and gold general are used only on the front side in the game, so only one magnet is enough for those pieces, and it is necessary to devise a way to make them adhere with the back side facing up. There will be no sex.

Moreover, as such a board game, it can be applied to Othello (registered trademark) as well as Japanese shogi. However, in that case, it is necessary to distinguish the front and back, but since it is a game that does not depend on the direction, it is only necessary to have the front and back discrimination function of the piece, and since there is only one type of the piece, all are the same. RFID tags may be used.

When applying to mahjong, it is not necessary to recognize the front and back of the direction, but on the contrary, it is meaningful whether the piece (tile) is in the horizontal state or the vertical state, and RFID for that recognition. It is necessary to make adjustments such as providing many tags and setting the position not only on the bottom but also on the side. Further, in the case of such mahjong, it is also effective to use a dice in which RFID tags are incorporated in each of the six sides of the dice.

On the contrary, in the case of Chinese chess, chess, etc., there are multiple types of pieces, but there are neither front nor back, and it does not depend on the direction of the pieces, so the front and back discrimination function of the pieces is unnecessary. In addition, in the case of Chinese chess, chess, etc., the pieces taken are not reused, so only your own pieces are used and the pieces on the enemy side are displayed on the display device.
