Hereinafter, examples of embodiments of the present invention will be described based on the drawings.

[1. First Embodiment] A system according to a first embodiment of the present invention will be described.

FIG. 1 shows an example of the configuration of a system 1 according to the first embodiment. System 1 is a system related to a game played using real objects placed on an object surface set in the real world. As will be described later, the system 1 includes a function as an identification system for identifying the types and states of objects placed on the object surface in the game. The system 1 also includes a function as a display control system that causes the display means to display an object placed on the object surface in the game.

For example, a card game played using cards corresponds to an example of "a game played using an object placed on a target surface." In the following, a battle-type card game (trading card game) in which a player sets a deck by combining arbitrary cards from the cards they own according to a predetermined rule and uses the deck to play against other players game) as an example, the system 1 according to the first embodiment will be described.

[1-1. Outline of Card Game] Before describing the configuration of the system 1, an outline of the card game will be described.

2A and 2B show an example of cards used in card games. The card 60 is a rectangular object made of material such as paper.

FIG. 2A shows an example of the appearance of surface 61 of card 60 . FIG. 2A shows a character card, which is a card representing a character, as an example of the card 60 .

As shown in FIG. 2A, information about the card 60 is written on the surface 61 of the card 60 . Since FIG. 2A shows a character card, information about the character is written on the surface 61 . For example, surface 61 includes parts P1, P2, P3, P4, P5. The part P1 indicates the name of the card 60 (character). The part P2 is an image of the character. Part P3 shows an explanation about the character. Part P4 indicates the attack power (ATK) and defense power (DEF) of the character. Part P5 indicates a card ID. The card ID is information for identifying each card type. For example, the appearance (design, text, etc.) of the front surface 61 of the card 60 is different for each card type, the cards 60 having the same appearance of the front surface 61 have the same card ID, and the cards 60 having different appearances of the front surface 61 are used. IDs are different. For example, cards 60 representing different characters have different card IDs. If there is only one type of card 60 showing characters with the same name, the cards 60 showing the same character have the same card ID. On the other hand, if there are multiple types of cards 60 with different appearances on the front side 61 as the cards 60 showing characters with the same name, the card IDs of the multiple types of cards 60 are different. For example, when there are multiple types of cards 60 with different rarities or ranks as cards 60 indicating characters with the same name, the card IDs of these multiple types of cards 60 are different.

FIG. 2A shows an example of a character card as an example of a card 60 used in a card game, but cards 60 representing characters other than characters are also used in card games. For example, a magic card indicating a spell or a trap card indicating a trap is used. Information about magic or traps is written on the surface 61 of the magic card or the trap card like the character card.

FIG. 2B shows an example of the appearance of the back surface 62 of the card 60. As shown in FIG. The back 62 of card 60 has an appearance common to all cards used in card games. That is, the back surface 62 of the card 60 has a common appearance regardless of the type of the card 60 . Therefore, the type of the card 60 cannot be specified from the appearance of the back surface 62. - 特許庁

The card game progresses by placing cards 60 on the game field by the first player and the second player who play against each other. FIG. 3 shows an example of the game field F. FIG. As shown in FIG. 3, the game field F includes a first player field F1, a second player field F2, and a common field F3.

The first player field F1 is an area for placing the cards 60 of the first player. The first player field F1 includes a plurality of zones Z1-Z14.

For example, zone Z7 is an area for placing the first player's deck as a deck. Here, a "deck" means a bundle of cards 60 in which a player arbitrarily combines the cards 60 owned by the player in accordance with a predetermined rule when playing a card game, and a "stock" means a pile of cards. , means a deck that is shuffled and placed face down. The first player can draw a card from the deck placed in zone Z7 and add it to his hand.

Zones Z2 to Z6 and Z8 to Z13 are areas for placing arbitrary cards 60 selected by the first player from his or her own hand.

For example, zones Z9 to Z13 are areas for the first player to place character cards out of his or her hand. The first player puts the character cards in the zones Z9 to Z13 from his/her hand, so that the character can be used for battle (attack etc.).

Zones Z2 to Z6 and Z8, for example, are areas for the first player to place magic cards or trap cards out of his or her hand. A first player can generate a magic or trap effect in a card game by placing magic cards or trap cards from his/her hand in zones Z2 to Z6 and Z8.

Also, for example, zone Z14 is an area for placing character cards of defeated characters, used magic cards or trap cards. Zone Z1 is an area for placing a stack of special cards 60 that can be placed in zones Z29 and Z30 of common field F3. The first player can place a card 60 in zone Z29 or Z30 from the stack of special cards 60 placed in zone Z1 under predetermined conditions.

The second player field F2 is an area for placing the cards 60 of the second player. The second player field F2 includes a plurality of zones Z15-Z28. The meanings and roles of the zones Z15 to Z28 are the same as those of the zones Z1 to Z14 of the first player field F1, so the explanation is omitted.

The shared field F3 is an area shared by the first player and the second player. The shared field F3 includes a plurality of zones Z29, Z30, and both the first player and the second player can place cards 60 in zones Z29, Z30 under predetermined conditions.

In the following description, zones Z1 to Z30 are collectively referred to as "zone Z" when there is no need to distinguish between them.

The card game is run on a turn basis. That is, in the card game, the turns of the first player and the turns of the second player are alternately and repeatedly executed.

On the first player's turn, the first player draws a card 60 from a pile of cards 60 placed in zone Z7 (the first player's deck) and adds the drawn card 60 to his or her hand. Under predetermined conditions, the first player places any card 60 from his hand in zones Z2-Z6 and Z8-Z13, or places any card 60 from a special stack of cards 60 placed in zone Z1. The card 60 placed on Z29, Z30 or placed on the game field F is used to attack the second player.

Similarly, on the turn of the second player, the second player draws a card from the pile of cards 60 placed in zone Z21 (the deck of the second player) and adds the drawn card 60 to his hand. Under predetermined conditions, the second player places any card 60 from his hand in zones Z16-Z20, Z22-Z27, or places any card 60 from a special stack of cards 60 placed in zone Z15. The card 60 placed on Z29, Z30 or placed on the game field F is used to attack the first player.

In a card game, a plurality of card placement formats are defined, and depending on the placement format, whether or not the cards have an effect on the progress or results of the card game or the content thereof changes.

FIG. 4 is a diagram for explaining an arrangement format of character cards. As shown in FIG. 4, in the card game, there are three types of character card placement formats: front attack display, back defense display, and front defense display.

"Front side attack display" is a state in which the character card is placed face up and vertically. “Face-up” is a state in which the card 60 is placed so that the front side 61 of the card 60 can be seen by the player. In other words, "face up" is a state in which the card 60 is placed so that the back surface 62 of the card 60 and the game field F face each other. "Portrait orientation" is a state in which the card 60 is placed so that the card 60 looks vertically long when viewed from the player. In other words, "vertically" means that the card 60 is placed so that the long side direction of the card 60 is parallel (or substantially parallel) to the longitudinal direction of the game field F. A player can fight based on the attack power (ATK) of the character card by placing the character card in face-up attack display.

"Back side defense display" is a state in which the character card is placed face down and sideways. "Face-down" is a state in which the card 60 is placed so that the player can see the back side 62 of the card 60 and cannot see the front side 61 of the card 60 . In other words, "face down" is a state in which the card 60 is placed so that the front side 61 of the card 60 and the game field F face each other. "Landscape" is a state in which the card 60 is placed so that the card 60 looks horizontally long when viewed from the player. In other words, "sideways" means that the card 60 is placed so that the long side direction of the card 60 is parallel (or substantially parallel) to the horizontal direction of the game field F. The player can fight based on the defensive strength (DEF) of the character card by placing the character card in face-down defense display.

"Front side defense display" is a state in which the character card is placed face up and sideways. The player can fight based on the defensive strength (DEF) of the character card by placing the character card in face-up defense display.

When placing the character cards on the game field F, in principle, the player can select either the front side attack display or the back side defense display as the placement format. A character card placed in face-down defense display changes to face-up defense display when it receives an attack from an opponent (1). When a player places a character card in face-down defense mode, the opponent cannot attack the character card without knowing the name or performance (attack power, defense power, etc.) of the character card. , and you will know the name and performance of the character card when you attack. A character card placed in face-down defense display may change to face-up defense display when the effect of a specific magic card is activated. Also, the player can change his/her own character card placed in the back-side defense display to the front-side attack display (2). Furthermore, the player can change the layout of his or her character cards placed on the game field F between the front attack display and the front defense display (3).

Similarly, in card games, a plurality of types of placement formats are defined as placement formats for magic cards or trap cards. For example, there are two types of arrangement forms for magic cards or trap cards: face-up display and back-side display. "Face display" is a state in which a magic card or a trap card is placed face up and vertically, and a state in which the effect of the magic indicated by the magic card or the trap indicated by the trap card is activated. On the other hand, "face-down display" is a state in which a magic card or trap card is placed face down and vertically, and the activation of the effect of the magic indicated by the magic card or the trap indicated by the trap card is on standby. be. A magic card or trap card that is placed face-down changes to face-up at the player's desired timing or when a predetermined activation condition is satisfied, and the effect of the magic or trap card indicated by the magic card or trap card is activated. do. If a player places a Spell Card or Trap Card face-down, the opponent will proceed with the battle without knowing the name or effect of the Spell Card or Trap Card, and the Spell Card will be displayed face-up at the time the Spell Card or Trap Card is placed face-down. Or you will know the names and effects of trap cards.

The player selects or changes the card arrangement format in consideration of the characteristics of the arrangement format as described above in order to make a bargain with the opponent.

In the card game, the first player wins and the second player loses when the second player's points (life points), which are reduced by attacks from the first player to the second player, become zero. On the other hand, when the points (life points) of the first player, which are reduced by attacks from the second player to the first player, become zero, the second player wins and the first player loses.

In this embodiment, the card 60 is used while being housed in a sleeve. FIG. 5 is a diagram for explaining the sleeve. As shown in FIG. 5, the sleeve 70 is a container for containing one card 60. As shown in FIG. The sleeve 70 is a rectangular bag-like object with three sides glued together and the remaining one side formed as an opening, through which the card 60 is accommodated in the sleeve 70 . The sleeve 70 is made of synthetic resin such as polypropylene. For example, the sleeve 70 is provided (sold, etc.) separately from the card 60 .

The sleeve 70 has a surface portion 71 and a back portion 72 . The surface portion 71 is a surface portion (facing surface portion) that faces the surface 61 of the card 60 when the card 60 is accommodated in the sleeve 70 . The back surface portion 72 is a surface portion (opposite surface portion) on the opposite side to the surface portion 71 and is a surface portion that faces the back surface 62 of the card 60 when the card 60 is housed in the sleeve 70 . As shown in FIG. 5, the card 60 is arranged such that the front surface 61 of the card 60 and the front surface portion 71 of the sleeve 70 face each other (in other words, the rear surface 62 of the card 60 and the rear surface portion 72 of the sleeve 70 face each other). so) is accommodated within the sleeve 70 .

A surface portion 71 of the sleeve 70 is transparent so that the surface 61 of the card 60 accommodated in the sleeve 70 can be visually recognized from the outside of the sleeve 70 through the surface portion 71 . Note that the entire surface portion 71 does not need to be transparent. ) need not be transparent. On the other hand, the back side 72 of the sleeve 70 is opaque and has the same appearance as the back side 72 of the other sleeves 70 . That is, the back surface portion 72 has an appearance common to all sleeves 70 . For this reason, individual sleeves 70 cannot be distinguished from the appearance of the back surface portion 72 . For example, backside portion 72 has the same appearance as backside 62 of card 60 .

The sleeve 70 has an IC tag 73 (RFID tag). The IC tag 73 is a device having a function of communicating via radio such as radio waves. For example, the IC tag 73 includes an IC chip and an antenna, receives a signal transmitted wirelessly from an IC tag reader via the antenna, and wirelessly transmits information stored in the IC chip in response to the reception of the signal. It is a passive type IC tag that replies to the IC tag reader via the . The IC tag 73 may have a function of writing and storing information received from an IC tag writer via an antenna in an IC chip. Further, the IC tag 73 is not limited to a passive IC tag, and may be an active IC tag.

For example, the IC tag 73 is provided at a position other than the surface portion 71 of the sleeve 70 so that the surface 61 of the card 60 is not hidden by the IC tag 73 and becomes difficult to see. In this embodiment, an IC tag 73 is provided on the inner surface of the back surface portion 72 of the sleeve 70 . For example, the IC tag 73 is attached to the inner surface of the back surface portion 72 with a seal or the like. Note that the antenna of the IC tag 73 may be printed on the inner surface of the back surface portion 72 . The IC chip of the IC tag 73 stores a tag ID that is information for uniquely identifying each IC tag 73 .

Since the back surface portion 72 of the sleeve 70 is opaque, the IC tag 73 cannot be visually recognized from outside the sleeve 70 . Therefore, even if there is a difference in the installation position of the IC tag 73 between the sleeves 70 or there is an individual difference in the IC tag 73 itself, the difference can be used as a clue to separate the individual IC tags 73 from the back surface 72 of the sleeve 70 . It is ensured that the sleeve 70 cannot be distinguished.

If there is no difference in the installation position of the IC tag 73 or the IC tag 73 itself, or if such a difference can be ignored and the IC tag 73 can be visually recognized from outside the sleeve 70, there is no particular problem. Back surface 72 of sleeve 70 may be transparent. Further, when both the surface portion 71 and the back surface portion 72 of the sleeve 70 are made transparent, the inner surface of the surface portion 71 may be provided with the IC tag 73 .

When the IC tag 73 is attached to a portion of the back surface portion 72 of the sleeve 70, the thickness of the portion where the IC tag 73 is attached is larger than that of the other portions, and the stability when a plurality of sleeves 70 are stacked is reduced. It may be damaged. For this reason, in order to make the thickness of the sleeve 70 uniform (or substantially uniform), for example, the thickness of the portion of the back surface portion 72 other than the portion where the IC tag 73 is placed is set to the thickness of the IC tag 73 . The thickness may be the same as the thickness, or the IC tag 73 (antenna) may be arranged over the entire inner surface (or a wide range) of the back surface portion 72 .

In this embodiment, the card 60 is used while being housed in the sleeve 70 . The sleeve 70 plays a role of protecting the card 60 from damage and the like, and also plays a role of specifying the type and condition of the card 60 placed on the game field F, as will be described later. Hereinafter, the card 60 housed in the sleeve 70 will be referred to as a "card 60S" for the sake of convenience in order to distinguish it from the card 60 itself. In other words, the card 60 and the sleeve 70 when the card 60 is accommodated in the sleeve 70 are regarded as one object and described as "card 60S".

[1-2. System Configuration] Returning to FIG. 1, the configuration of the system 1 according to the first embodiment will be described. As shown in FIG. 1, the system 1 includes a game board 10, a photographing device 30, an information processing device 40, and a display terminal device 50. FIG.

For example, the reader 20-1 corresponds to zone Z1 and is installed at a position corresponding to zone Z1. Specifically, the reader 20-1 is installed below the zone Z1 and is used to read the information stored in the IC tag 73 of the card 60S placed in the zone Z1. The same applies to the readers 20-2 to 20-30. Hereinafter, when there is no need to distinguish between the reading devices 20-1 to 20-30, they are collectively referred to as "reading device 20".

The card 60 and the surface portion 71 and the back surface portion 72 of the sleeve 70 are made of a material that does not interfere with signal transmission/reception between the IC tag 73 and the reader 20 . Therefore, even if the card 60S is placed face up or face down in the zone Z, the reader 20 installed under the zone Z reads the information stored in the IC tag 73 of the card 60S. be able to.

Further, even when a plurality of cards 60S are stacked in one zone Z, the reader 20 installed under the zone Z stores data in the IC tag 73 of each of the plurality of cards 60S. information can be read.

Further, the reader 20 installed under the zone Z is installed away from the other zone Z, and can read the information stored in the IC tag 73 of the card 60S placed in the other zone Z. It's not supposed to.

The operation unit 44 , the display unit 45 , and the audio output unit 46 may be provided in the information processing device 40 itself, or may be provided as an external device connected to the information processing device 40 . For example, the display unit 45 may be a head mounted display (HMD), a monitor, a television receiver, a projector, or the like connected to the information processing device 40 as an external device.

Based on the read result data of the reading device 20 and the photographed image of the photographing device 30, the information processing device 40 determines the type and state of the card 60S placed on the game field F (that is, the state of being housed in the sleeve 70). to specify the type and state of the card 60 placed on the game field F). Further, the information processing device 40 causes the display terminal device 50 to display a game field image showing the current situation of the game field F based on the identification result. The processing executed by the information processing device 40 will be described later (see FIGS. 10, 12, 13, 18, etc.).

The display terminal device 50 is a device capable of displaying images. For example, the display terminal device 50 is a device for spectators watching a card game match. Specifically, the display terminal device 50 is a terminal device (for example, a smartphone, a tablet computer, a laptop computer, a desktop computer, etc.) used by individual spectators, and as shown in FIG. The computer includes a unit 51 , a storage unit 52 , a communication unit 53 , an operation unit 54 , a display unit 55 and an audio output unit 56 . The control unit 51, the storage unit 52, the communication unit 53, the operation unit 54, the display unit 55, and the audio output unit 56 are the control unit 41, the storage unit 42, the communication unit 43, the operation unit 44, the display unit 45, and the audio output unit. 46. Although the operation unit 54 and the display unit 55 are shown separately in FIG. 1, the operation unit 54 and the display unit 55 may be integrally formed as a touch panel. The operation unit 54 may be a pointing device such as a mouse, a button (key), a lever (stick), or the like. The operation unit 54 may be operated by the audience by voice or gesture.

In the following description, it is assumed that the display terminal device 50 is a terminal device (such as a smart phone) used by individual spectators, but the display terminal device 50 is not limited to this. For example, the display terminal device 50 may be a display-only device having only a display function. For example, the display terminal device 50 may be a large monitor installed in a venue with multiple spectators and viewed by multiple spectators.

The display unit 55 of the display terminal device 50 displays, for example, a game field image showing the current situation of the game field F (game board 10). A spectator can grasp the current situation of the game field F by looking at the game field image.

FIG. 7 shows an example of the situation of the game field F (game board 10), and FIG. 8 shows an example of the game field image in the situation shown in FIG.

In the situation shown in FIG. 7, card 60S-1 is placed in zone Z10 in face-down defense display. Also, card 60S-2 is placed in zone Z12 in face-up attack display. Furthermore, card bundles 600-1 (first player's deck), 600-2, 600-3 (second player's deck), and 600-4, which are a plurality of cards 60S stacked face down, are zone Z7. , Z1, Z21 and Z15 respectively. It is assumed that card bundle 600-1 contains 50 cards 60S, and card bundle 600-2 contains 12 cards 60S. It is also assumed that card bundle 600-3 contains 45 cards 60S, and card bundle 600-4 contains 15 cards 60S.

As shown in FIG. 8, the game field image G shows the current state of the game field F. As shown in FIG. Zones Z1 to Z30 are drawn on the game field image G. FIG. The game field image G shown in FIG. 8 includes parts PA-1, PA-2, PA-3, PA-4, PB-1 and PB-2.

Part PA-1 is an object corresponding to card bundle 600-1 placed in zone Z7 and displayed in association with zone Z7. Part PA-2 is an object corresponding to card stack 600-2 placed in zone Z1, and is displayed in association with zone Z1. Part PA-3 is an object corresponding to card stack 600-3 placed in zone Z21 and displayed in association with zone Z21. Part PA-4 is an object corresponding to card bundle 600-4 placed in zone Z15 and displayed in association with zone Z15. The numerical value written on part PA-1 indicates the number of cards 60S included in card bundle 600-1. The same is true for parts PA-2 to PA-4.

The part PB-1 is an object corresponding to the card 60S-1 placed in the zone Z10 and displayed in association with the zone Z10. In the situation shown in FIG. 7, since the card 60S-1 is placed in the zone Z10 in the face-down defense display, the part PB-1 is an image showing the card 60 placed sideways and face down (that is, the card 60 placed sideways). An image showing the back side 62 of the card 60 that has been drawn) is displayed at a position corresponding to the zone Z10. In other words, as part PB-1, an image corresponding to the type of card 60 is not displayed, and an image independent of the type of card 60 is displayed at a position corresponding to zone Z10.

Part PB-2 is an object corresponding to card 60S-2 placed in zone Z12, and is displayed in association with zone Z12. In the situation shown in FIG. 7, since the card 60S-2 is placed in the zone Z12 in face-up attack display, an image showing the card 60 placed vertically and face-up as the part PB-2 (that is, An image showing the surface 61 of the placed card 60) is displayed at a position corresponding to the zone Z12. In other words, as part PB-2, unlike part PB-1, an image corresponding to the type of card 60 is displayed at a position corresponding to zone Z12.

Part PB-1 is associated with processing for displaying information on card 60S-1 placed in zone Z10. Therefore, when a designation operation for designating the part PB-1 (for example, a tap operation for the part PB-1, etc.) is accepted, the information of the card 60S-1 is displayed. FIG. 9 shows an example of the game field image G when the designation operation of the part PB-1 is accepted. When the operation of designating the part PB-1 is accepted, as shown in FIG. 9, an image showing the surface 61 of the card 60S-1 placed in the zone Z10 is displayed as the part PC.

Normally, the spectator cannot grasp the name and performance of the card 60S-1 placed face down, but in this embodiment, the part PC as shown in FIG. 9 is displayed in response to the operation of specifying the part PB-1. Therefore, the spectator can grasp the name and performance of the face-down card 60S-1. Instead of displaying the image showing the surface 61 of the card 60S-1 as the parts PC, a text message showing the name and performance of the card 60S-1 may be displayed as the parts PC.

Similar to the part PB-1, the part PB-2 is associated with processing for displaying information on the card 60S-2 placed in the zone Z12. Therefore, when the operation of designating the part PB-2 is accepted, the image showing the surface 61 of the card 60S-2 is displayed as the part PC. Since the part PC is larger than the part PB-2, the spectator can easily grasp the name and performance of the card 60S-2 placed in the zone Z12 by referring to the part PC.

Part PA-1 may be associated with processing for displaying a list of cards 60S included in card bundle 600-1 placed in zone Z7. Then, a list of the cards 60S included in the card bundle 600-1 may be displayed according to the designation operation of the part PA-1. In this way, the spectator may be able to grasp the list of cards 60S included in the card stack 600-1 placed in zone Z7. The same is true for parts PA-2 to PA-4.

Further, in the above description, the game field image G displayed on the display unit 55 of the display terminal device 50 changes according to the spectator's operation on the display terminal device 50 (for example, from the state shown in FIG. 8 to the state shown in FIG. 9). However, the game field image G displayed on the display unit 55 of the display terminal device 50 may be changed according to the operation performed on the information processing device 40. . For example, the parts PC shown in FIG. 9 is displayed in the game field image G in response to a designation operation performed by a representative who is playing a card game or commenting on it using the operation unit 44 of the information processing device 40. You may do so.

Also, not only the game field image G but also the image captured by the image capturing device 30 may be displayed on the display unit 55 of the display terminal device 50 . For example, both the game field image G and the image captured by the image capturing device 30 may be displayed on the display section 55 . Further, for example, the image displayed on the display unit 55 may be switched between the game field image G and the image captured by the image capturing device 30 in accordance with a predetermined switching instruction.

[1-3. Processing] The processing executed by the system 1 will be described.

[1-3-1] As will be described later, the information processing device 40 executes identification processing for identifying the type and state of the card 60S placed on the game field F based on the reading result of the reading device 20. FIG. For this identification process, the card ID of the card 60 and the sleeve 70 containing the card 60 must be associated. Therefore, prior to starting the card game, an association process for associating the card ID of the card 60 with the sleeve 70 containing the card 60 is executed.

[1-3-1-1] FIG. 10 is a flowchart showing an example of association processing. For example, the player places one card 60S from his/her own deck vertically and face up in a predetermined zone Z (for example, zone Z11) in the game field F. FIG. In this state, the association processing shown in FIG. 10 is executed.

As shown in FIG. 10, first, the control unit 41 of the information processing device 40 acquires an image captured by the imaging device 30 (S400). Then, the control unit 41 identifies the card ID of the card 60S shown in the photographed image (that is, the card ID of the card 60 placed in the zone Z while housed in the sleeve 70) from the photographed image (S402). .

For example, in the storage unit 42, a photographed image of the game field F on which the card 60S is placed and the card ID (correct answer data) of the card 60S are generated by executing machine learning based on learning data. A learned model (a model for specifying the card ID of the card 60S shown in the photographed image) is stored in advance. Then, in step S402, the control unit 41 uses the learned model to identify the card ID of the card 60S appearing in the captured image.

Note that the storage unit 42 may store in advance feature data in which the card ID of the card 60S is associated with appearance feature information indicating the appearance features of the card 60S. Then, in step S402, the control unit 41 analyzes the photographed image to extract the appearance characteristic information of the card 60S shown in the photographed image. The card ID associated with the external appearance feature information) may be identified as the card ID of the card 60S appearing in the captured image.

After executing step S402, the control unit 41 acquires the tag ID read by the reader 20 (S404). When the card 60S is placed in the zone Z, the tag ID stored in the IC tag 73 of the card 60S is read by the reader 20 installed under the zone Z, and the read tag ID is It is supplied to the information processing device 40 . The control unit 41 acquires the tag ID supplied in this manner.

After executing step S404, the control unit 41 registers the association between the card ID specified in step S402 and the tag ID acquired in step S404 in the association data D1 (S406).

FIG. 11 shows an example of the association data D1 stored in the storage unit 42. As shown in FIG. The association data D1 includes "card ID" and "tag ID" fields. A "card ID" field is a field for registering a card ID, and a "tag ID" field is a field for registering a tag ID.

In step S406, the control unit 41 adds a new record to the association data D1, and converts the card ID specified in step S402 and the tag ID acquired in step S404 to the "card ID" and "tag ID" of the added record. ID” field.

After execution of step S406, a completion notification indicating that the association processing has been completed is output. For example, an image indicating the notification of completion is displayed on the display unit 45, or a sound indicating the notification of completion is output from the audio output unit 46. In response to the completion notification, the player removes the card 60S placed in the zone Z, and places the next card 60S from his or her deck in the zone Z vertically and face up. In this state, the association processing shown in FIG. 10 is executed again.

By executing the association process shown in FIG. 10 for each card 60S included in the first player's deck, information on all cards 60S included in the first player's deck is registered in the association data D1. Information of all cards 60S included in the deck of the second player is registered in the association data D1 by executing the association processing shown in FIG. 10 for each card 60S included in the deck of the second player. be.

[1-3-1-2] The association process is not limited to the process shown in FIG. FIG. 12 is a flowchart showing another example of association processing. Instead of the association processing shown in FIG. 10, the association processing shown in FIG. 12 may be executed.

The association process shown in FIG. 12 is based on the premise that an IC tag writer for writing information to the IC tag 73 is installed under the zone Z described above. In the following description, it is assumed that the reader 20 installed under the zone Z is an IC tag reader/writer having both IC tag reader and IC tag writer functions.

As shown in FIG. 12, first, the control unit 41 of the information processing device 40 acquires an image captured by the imaging device 30 (S420). Then, the control unit 41 identifies the card ID of the card 60S appearing in the captured image from the captured image (S422). The processes of steps S420 and S422 are the same as steps S400 and S402 of FIG.

After executing step S422, the control section 41 writes the card ID specified in step S422 to the IC tag 73 of the card 60S placed in the zone Z (S424). That is, the control unit 41 sends an instruction to write the card ID identified in step S422 to the reader 20 placed under the zone Z above. Then, in response to the write instruction, the reader 20 writes the card ID specified in step S422 to the IC tag 73 of the card 60S placed in the zone Z above.

By executing the association process shown in FIG. 12 for each card 60S included in the first player's deck, the IC tag 73 of each card 60S included in the first player's deck has the card ID of the card 60S. is stored. 12 is executed for each card 60S included in the deck of the second player, the card 60S is attached to the IC tag 73 of each card 60S included in the deck of the second player. card ID is stored. In this case, the association between the card ID of the card 60 and the sleeve 70 containing the card 60 is not stored as association data D1 as shown in FIG. will be remembered.

[1-3-1-3] Here, it has been described that the system 1 is used to execute the association process, but it is not essential to use the system 1 to execute the association process. For example, an associating system including a photographing device and an IC tag reader (IC tag reader/writer) may be prepared separately from the system 1 and used to perform the associating process. Further, the association need only be completed when the card game is started, and the timing of executing the association need not be immediately before the card game is started.

[1-3-2] During play of the card game, the information processing device 40 executes identification processing for identifying the type and state of the cards 60S placed on the game field F. FIG. FIG. 13 is a flowchart showing an example of specific processing. Note that the specifying process shown in FIG. 13 is based on the premise that the association data D1 shown in FIG.

As shown in FIG. 13, first, the control unit 41 of the information processing device 40 acquires an image captured by the imaging device 30 (S430). Then, the control unit 41 identifies the position and orientation of the card 60S placed on the game field F from the captured image (S432).

In this embodiment, for example, as shown in FIG. 14, 35 areas A1 to A35 are set by dividing the photographed image I into 5 vertical×7 horizontal areas. Among them, areas A1 to A30 are set so as to correspond to zones Z1 to Z30 of the game field F. As shown in FIG. It should be noted that hereinafter, when there is no need to specify each of the regions A1 to A35, they are collectively referred to simply as “region A”.

In step S432, the control unit 41 specifies whether or not the card 60S is shown in each area A of the captured image, and the orientation of the shown card 60S (vertical/horizontal orientation or front/back orientation). Here, "identifying the vertical and horizontal orientation of the card 60S" means identifying whether the card 60S is placed vertically or horizontally, and "identifying the front and back orientation of the card 60S." is to specify whether the card 60S is placed face up or face down.

For example, in the storage unit 42, a machine is stored based on learning data including a photographed image of the game field F on which the card 60S is placed, and correct data indicating the area A on which the card 60S is placed and the orientation of the card 60S. A learned model generated by executing learning (a model for specifying whether or not the card 60S is shown in each area A of the photographed image and the orientation of the card 60S shown) is stored in advance. . Then, in step S432, the control unit 41 uses the learned model to specify whether or not the card 60S is shown in each area A of the captured image and the direction of the card 60S shown.

For each card 60S, the storage unit 42 stores in advance data that associates the orientation of the card 60S with appearance characteristic information indicating the appearance characteristics of the card 60S when placed in that orientation. You can leave it. Then, in step S422, the control unit 41 analyzes the photographed image to determine whether or not the appearance feature information of the card 60S is extracted from the area A of the photographed image. It may be specified whether or not the card 60S is shown in the area A, or the orientation of the card 60S appearing in the area A may be specified from the extracted appearance feature information.

The identification result in step S432 is registered in the first identification result data D2. FIG. 15 shows an example of the first identification result data D2. As shown in FIG. 15, the first identification result data D2 includes "area ID", "vertical/horizontal flag", and "front/back flag" fields.

The "area ID" field indicates an area ID that is information that uniquely identifies each area A set in the captured image. The “vertical/horizontal flag” field is a field for registering a vertical/horizontal flag indicating the result of identifying the vertical/horizontal direction of the card 60S appearing in the area A. FIG. For example, if the card 60S is identified as being oriented vertically, the value "0" is registered in the "portrait/horizontal flag" field, and if the card 60S is identified as being oriented horizontally, the value "1" is registered. It is registered in the "vertical/horizontal flag" field. The "front/back flag" field is a field for registering a front/back flag indicating the identification result of the front/back orientation of the card 60S shown in the area A. FIG. For example, if the card 60S is identified as face up, the value "0" is registered in the "front/back flag" field, and if the card 60S is identified as face down, the value "1" is registered. It is registered in the "front and back flag" field. When the card 60S is not shown in the area A, the "vertical/horizontal flag" and "front/back flag" fields are set to null (null). Note that hereinafter, among the records of the first identification result data D2, the record in which "An" (n: natural number) is registered in the "area ID" field is referred to as "the record of the area ID "An"". do.

For example, in the situation shown in FIG. 7, in step S432, (a) the card 60S is shown in each of the areas A1, A7, A10, A12, A15, and A21, and (b) the card 60S is shown in the area A10. (c) the orientation of the card 60S reflected in the area A12 is vertical and face up; and (d) the areas A1, A7, A15, and A21 It is specified from the photographed image that the card 60S in the photograph is facing vertically and face down, and the specified result is registered in the first specified result data D2.

After executing step S432, the control section 41 acquires the read result data of each reader 20 supplied from the game board 10 (S434), and the position and card ID of the card 60S placed on the game field F are read as the read result. Identify from the data (S436).

For example, in the situation shown in FIG. 7, the reader 20-10 installed under the zone Z10 reads the tag ID stored in the IC tag 73 of the card 60S-1 placed in the zone Z10. , the tag ID is supplied to the information processing device 40 as read result data. Then, the control unit 41 refers to the association data D1 to identify the card ID associated with the tag ID read by the reader 20-10. Thus, the card ID of the card 60S-1 placed in zone Z10 is specified.

Similarly, the reader 20-12 installed under the zone Z12 reads the tag ID stored in the IC tag 73 of the card 60S-2 placed in the zone Z12, and reads the tag ID as the read result. It is supplied to the information processing device 40 as data. Then, the control unit 41 refers to the association data D1 to identify the card ID associated with the tag ID read by the reader 20-12. Thus, the card ID of the card 60S-2 placed in zone Z12 is specified.

Further, the reader 20-7 installed under the zone Z7 reads the tag ID stored in the IC tag 73 of each card 60S included in the card bundle 600-1 placed in the zone Z7, These tag IDs are supplied to the information processing device 40 as read result data. Then, the control unit 41 refers to the association data D1 to identify the card ID associated with each tag ID read by the reader 20-7. In this way, the card ID of each card 60S included in card stack 600-1 placed in zone Z7 is identified. Card IDs are identified for zones Z1, Z15, and Z21 in the same manner as for zone Z7.

The identification result in step S436 is registered in the second identification result data D3. FIG. 16 shows an example of the second identification result data D3. As shown in FIG. 16, the second identification result data D3 includes "reader ID" and "card ID" fields.

A “reader ID” field indicates a reader ID that is information that uniquely identifies each reader 20 . In FIG. 16, the reader ID of the reader 20-n (n: natural number) is described as "Rn". The “card ID” field is a field for registering the card ID specified from the reading result data of the reading device 20 . For the reader 20 that did not read the tag ID stored in the IC tag 73, the "card ID" field is set to blank (null). In the following description, among the records of the second identification result data D3, the record in which "Rn" (n: natural number) is registered in the "reader ID" field is referred to as the "record of the reader ID "Rn"". and described.

For example, in the case of the situation shown in FIG. 7, the card ID specified from the tag ID read by the reader 20-10 (that is, The card ID of the card 60S-1 placed in zone Z10) is registered. Also, for the "card ID" field of the record with the reader ID "R12", the card ID specified from the tag ID read by the reader 20-12 (that is, the card 60S-2 placed in zone Z12). card ID) is registered.

Furthermore, for the "card ID" field of the record with the reader ID "R7", a list of card IDs identified from the multiple tag IDs read by the reader 20-7 (that is, A list of card IDs of cards 60S included in card bundle 600-1 is registered. The same applies to the "card ID" fields of the records with reader IDs "R1", "R15", and "R21". The "card ID" field of records other than the records with reader IDs "R1", "R7", "R10", "R12", "R15", and "R21" is set to blank (null).

11 has been registered in the storage unit 42 by the association processing shown in FIG. If the ID is registered in the IC tag 73 of the card 60S, the process described below is executed in step S436.

For example, in the situation shown in FIG. 7, the reader 20-10 installed under the zone Z10 reads the card ID stored in the IC tag 73 of the card 60S placed in the zone Z10, The card ID is supplied to the information processing device 40 as read result data. Then, the control unit 41 registers the card ID read by the reader 20-10 in the "card ID" field of the record with the reader ID "R10". The same is true for zone Z12.

Further, the reader 20-7 installed under the zone Z7 reads the card ID stored in the IC tag 73 of each card 60S included in the card bundle 600-1 placed in the zone Z7, These card IDs are supplied to the information processing device 40 as read result data. Then, the control unit 41 registers the plurality of card IDs read by the reader 20-7 in the "card ID" field of the record with the reader ID "R7". The same applies to zones Z1, Z15 and Z21.

After executing step S436, the control section 41 generates the game field situation data D4 based on the first specified result data D2 and the second specified result data D3 (S438).

FIG. 17 shows an example of the game field situation data D4. The game field situation data D4 is data indicating the current situation of the game field F. FIG. More specifically, the game field situation data D4 is the current situation of each zone Z in the game field F (whether or not the card 60S is placed in the zone Z, and whether or not the card 60S is placed in the zone Z). type and arrangement format).

As shown in FIG. 17, the game field status data D4 includes "zone ID", "card ID", "vertical/horizontal flag", and "front/back flag" fields. A “zone ID” field indicates a zone ID that is information for uniquely identifying each zone Z within the game field F. FIG. The "card ID" field is the same as the "card ID" field of the second identification result data D3. The "vertical/horizontal flag" and "front/back flag" fields are the same as the "vertical/horizontal flag" and "front/back flag" fields of the first identification result data D2. Note that, hereinafter, among the records of the game field situation data D4, a record in which "Zn" (n: natural number) is registered in the "zone ID" field is referred to as a "record of the zone ID "Zn"". .

In step S438, the control unit 41 collates the "region ID" field of the first identification result data D2 with the "reader ID" field of the second identification result data D3, and compares the first identification result data D2 with the second identification result data D3. The game field situation data D4 is generated by synthesizing it with the specified result data D3.

For example, the record with the reader ID "R1" among the records of the second identification result data D3 and the record with the area ID "A1" among the records of the first identification result data D2 both correspond to the zone Z1. 20-1 or area A1, and these records correspond to each other. Therefore, the control unit 41 detects the card ID registered in the "card ID" field of the record with the reader ID "R1" among the records of the second identification result data D3 and the record of the first identification result data D2. A combination of the vertical/horizontal flag and the front/back flag registered in the "vertical/horizontal flag" and "front/back flag" fields of the record with the area ID "A1", which is the record corresponding to the reading device ID "R1", is assigned to the zone Z1 is registered in the game field situation data D4 as information indicating the current situation of the game field. That is, the control unit 41 registers the combination in the "card ID", "vertical/horizontal flag", and "front/back flag" fields of the record of the zone ID "Z1" among the records of the game field situation data D4. The same is true for zones Z2-Z30.

[1-3-3] Display control processing for displaying the game field image G on the display unit 55 of the display terminal device 50 is executed during play of the card game. For example, the storage unit 42 stores card data in which the card ID is associated with information and an image (surface 61) of the card 60, and the game field image G consists of this card data and the game field situation data D4. displayed based on FIG. 18 shows an example of display control processing.

As shown in FIG. 18, the control unit 41 of the information processing device 40 transmits data regarding the game field image G to the display terminal device 50 via the communication unit 43 (S440). Receives the data via (S500). Then, the control section 51 of the display terminal device 50 causes the display section 55 to display the game field image G based on the data (S502).

Here, "data relating to the game field image G" is data necessary for displaying the game field image G on the display terminal device 50 (display unit 55). For example, the card data and the game field situation data D4 correspond to an example of "data relating to the game field image G". The card data may be stored in the storage unit 52 of the display terminal device 50 in advance, in which case it is not necessary to transmit the card data to the display terminal device 50 . The game field image G itself may be transmitted to the display terminal device 50 as "data relating to the game field image G".

When generating the game field image G, it is determined whether the front/back flag of the card 60S registered in the game field situation data D4 is "1" (in other words, the orientation of the card 60S specified in step S432). is face down). Then, parts representing the card 60S are displayed in the game field image G according to the determination result.

For example, if the front/back flag of the card 60S is not "1" (in other words, if the orientation of the card 60S identified in step S432 is face up instead of face down), the part indicating the card 60S is, for example, An image showing the surface 61 of the card 60S is displayed in the game field image G, such as the part PB-2 shown in FIG. That is, as a part representing the card 60S, an image corresponding to the card ID of the card 60S registered in the game field situation data D4 (in other words, an image corresponding to the type of the card 60S specified in step S432) is displayed. be done.

On the other hand, when the front/back flag of the card 60S is "1" (that is, when the orientation of the card 60S identified in step S432 is face down), the part indicating the card 60S is shown in FIG. An image showing the back surface 62 of the card 60S is displayed in the game field image G, such as the part PB-1. That is, as a part representing the card 60S, an image independent of the card ID of the card 60S registered in the game field situation data D4 (in other words, an image independent of the type of the card 60S specified in step S432) is displayed. be done.

Note that the game field image G may be displayed on the display section 45 of the information processing device 40 . That is, the control section 41 of the information processing device 40 may cause the display section 45 to display the game field image G based on the game field situation data D4.

[1-3-4] FIG. 19 shows an example of processing repeatedly executed by the display terminal device 50 while the game field image G is being displayed.

As shown in FIG. 19, the control unit 51 of the display terminal device 50 determines whether or not a card specifying operation has been accepted (S510). "Card designating operation" is an operation of designating a card 60S displayed in the game field image G. FIG. For example, in the case of the game field image G shown in FIG. 8, the specifying operation of the part PB-1 or PB-2 (for example, tapping the part PB-1 or PB-2, etc.) corresponds to the "card specifying operation".

When it is determined that the card specifying operation has been received (S510: Yes), the control unit 51 displays the card image of the specified card 60S (S512). For example, the parts PC shown in FIG. 9 corresponds to the "card image". For example, in a state where the game field image G shown in FIG. The part 51 displays the parts PC showing the front side 61 of the card 60S-1 placed in the zone Z10.

Although omitted in FIG. 19, when a predetermined erasure instruction operation (for example, designation operation for designating a parts PC) is performed while the parts PC is displayed, the control unit 51 erases the parts PC.

Note that when the display terminal device 50 has received the card designation operation, the display terminal device 50 transmits a notification to the effect that the card designation operation has been received to the information processing device 40, and the control unit 41 of the information processing device 40 executes the operation shown in FIG. may be displayed on the display terminal device 50 by generating the game field image G as shown in FIG.

When the game field image G is displayed on the display unit 45 of the information processing device 40, the processing shown in FIG. 19 is executed by the control unit 41 of the information processing device 40. FIG.

[1-4. Effect] According to the first embodiment described above, not only the photographed image of the photographing device 30 that photographs the game field F, but also the reading result of the reading device 20 that reads the information stored in the IC tag 73 of the card 60S. By using this, the type and state (position, orientation, etc.) of the card 60S placed on the game field F can be specified. According to the first embodiment, matters that cannot be specified (or are difficult to specify) from the captured image of the imaging device 30 can be specified based on the reading result of the reading device 20 .

For example, even when the card 60S is placed face down on the game field F (that is, when the card 60S is placed so that the front side 61 does not appear in the image captured by the image capturing device 30), the reading device 20, the type of the card 60S can be specified, and the information (name, performance, etc.) written on the surface 61 of the card 60S can be specified. Further, for example, even if the card 60S has been subjected to hologram processing or the like, the type of the card 60S can be specified based on the reading result of the reading device 20, or the information (name, performance, etc.) written on the surface 61 of the card 60S can be identified. etc.) can be specified. Also, for example, even when a plurality of cards 60S are stacked, the types of these cards 60S can be specified based on the reading result of the reader 20. FIG.

Further, in the first embodiment, the identification result (first identification result) from the photographed image of the photographing device 30 includes the identification result regarding the position and orientation of the card 60S, and the identification result (first identification result) from the reading result of the reading device 20 is included. Since the second identification result) includes the identification result regarding the position and type of the card 60S, the identification result (location identification result) regarding the position of the card 60S is included in both the first identification result and the second identification result. . Therefore, even if a plurality of cards 60S are placed on the game field F, the same card 60S can be identified by collating the position identification results included in both the first identification result and the second identification result. A combination of a first identification result and a second identification result for can be identified. That is, even when a plurality of cards 60S are placed on the game field F, the combination of type, position and orientation can be specified for each individual card 60S.

Further, in the first embodiment, since the IC tag 73 is provided on the sleeve 70, even if the card 60 itself does not have an IC tag, the card 60 can be stored in the sleeve 70 and used. can be specified from the reading result of the reading device 20.

That is, since the card 60 itself does not need to have an IC tag, it is possible to use an existing card 60 that does not have an IC tag, for example.

Also, if the card 60 itself has an IC tag, the card 60 cannot be used if the IC tag of the card 60 breaks down, and the player may feel dissatisfied. Some of the cards 60 are highly rare, and if such a highly rare card 60 becomes unusable due to a failure of the IC tag, the player may feel great dissatisfaction. In this regard, if the sleeve 70 has the IC tag 73, even if the IC tag 73 fails, the card 60 can be used continuously by replacing the sleeve 70. FIG.

Further, in the first embodiment, since the IC tag 73 is provided on the back surface portion 72 of the sleeve 70, it is possible to prevent the front surface 61 of the card 60 accommodated in the sleeve 70 from being hidden by the IC tag 73 and becoming difficult to see. .

Further, in the first embodiment, since the appearance of the back surface portion 72 of the sleeve 70 is common to all the sleeves 70 , it is possible to ensure that individual sleeves 70 cannot be distinguished from the appearance of the back surface portion 72 .

Further, in the first embodiment, since the game field image G is displayed on the display terminal device 50, the spectators (persons viewing the display terminal device 50) can easily grasp the current situation of the game field F. FIG.

Further, in the first embodiment, even when the card 60S is placed face down on the game field F (that is, when the card 60S is placed with the front side 61 invisible), the front side of the card 60S 61 is displayed in the game field image G, the spectator will not be able to know the information written on the surface 61 of the card 60S placed face down (name, performance, etc.). etc.) can be provided. As a result, it is possible to improve the interest in watching the card game as a spectator.

Note that in the first embodiment, when a designation operation for designating the card 60S placed face down (for example, a designation operation for designating the part PB-1 in FIG. 8) is received, the part indicating the front surface 61 of the card 60S is received. Since the PC is displayed, for example, in principle, the information (name, performance, etc.) of the card 60S placed face down cannot be known, and the spectator performs the above designation operation only when desired. By doing so, it is possible to know

[1-5. Modification] A modification of the first embodiment will be described.

[1-5-1] In the embodiment described above, the sleeve 70 has the IC tag 73, but the sleeve 70 does not have the IC tag 73. may be housed in the sleeve 70.

For example, an object 80 accommodated in a sleeve 70 together with a card 60 may have an IC tag 73, as shown in FIG. The object 80 is made of a material that does not interfere with signal transmission/reception between the IC tag 73 and the reader 20 . For example, the object 80 is a sheet-like object having a shape similar to that of the card 60 . In the example shown in FIG. 20 , the shape and size of the object 80 are the same (or substantially the same) as the card 60 , but the shape and size of the object 80 may be different from those of the card 60 . Note that the IC tag 73 may be attached to either surface of the object 80 .

The card 60 is accommodated in the sleeve 70 so that the surface 61 and the surface portion 71 of the sleeve 70 face each other, and the object 80 is accommodated between the back surface 62 of the card 60 and the back surface portion 72 of the sleeve 70. . When used in a card game, both the card 60 and the object 80 are stored in the sleeve 70 when used. It is sufficient that both the card 60 and the object 80 are accommodated in the sleeve 70 when used in the card game. They do not have to be housed in the sleeve 70 all at once. The object 80 may be accommodated in the sleeve 70 after the card 60 is accommodated in the sleeve 70 , or the card 60 may be accommodated in the sleeve 70 after the object 80 is accommodated in the sleeve 70 . Card 60 and object 80 may be housed together in sleeve 70 at the same time.

Even if the object 80 as described above is accommodated in the sleeve 70 together with the card 60, as in the case where the IC tag 73 is attached to the sleeve 70, items that cannot be specified (or are difficult to specify) from the image captured by the image capturing device 30 can be detected. It becomes possible to specify from the reading result of the reading device 20 . Also, even if the card 60 itself does not have an IC tag, by storing the card 60 in the sleeve 70 together with the object 80, the type and state of the card 60 can be specified from the reading result of the reading device 20. be possible.

[1-5-2] The IC tag 73 may be provided on the card 60 itself (for example, the back surface 62). Even in this way, matters that cannot be specified (or are difficult to specify) from the photographed image of the photographing device 30 can be specified based on the reading result of the reading device 20 .

[1-5-3] Before starting the card game, when the player's deck is placed as a deck in zone Z7 or Z21, the specific processing shown in FIG. 13 is executed, based on the game field situation data D4, It may be determined whether or not the player's deck placed in zone Z7 or Z21 complies with the rules. Then, if the deck does not comply with the rules, a warning notification may be output.

[1-5-4] In the above, it is assumed that the information stored in the IC tag 73 of the card 60S placed in zone Z is not read by the reader 20 installed under other zone Z. As described above, when the information stored in the IC tag 73 of the card 60S is read by a plurality of readers 20, the strength of the signal received from the IC tag 73 among the plurality of readers 20 The reading device 20 having the strongest value may be regarded as the reading device 20 that has read the information stored in the IC tag 73 . For example, when the information stored in the IC tag 73 of the card 60S is read by the readers 20-9 and 20-10, the received signal strength of the reader 20-10 is stronger than that of the reader 20-9. For example, it may be specified that the card 60S is placed in the zone Z10.

[1-5-5] In the embodiment described above, the readers 20-1 to 20-30 were installed at a plurality of positions corresponding to zones Z1 to Z30, respectively. A reader 20 having antennas arranged in a grid pattern may be installed inside the housing 11 of the game board 10 .

For example, as shown in FIG. 21, as an antenna of the reading device 20, a plurality of first antennas 21 extending in a first direction (for example, vertical direction) are arranged at predetermined intervals, and a plurality of first antennas 21 extending in a second direction (for example, horizontal direction) are arranged at predetermined intervals. may be arranged at predetermined intervals. In this case, the combination of the first antenna 21 and the second antenna 22 that received the signal from the IC tag 73 (in other words, the combination of the first antenna 21 and the second antenna 22 with the strongest signal strength received from the IC tag 73 ), the position where the card 60S is placed can be identified. For example, the card 60S is placed at the intersection of the first antenna 21 and the second antenna 22 that have received the signal from the IC tag 73 (in other words, the first antenna 21 and the second antenna 22 with the strongest received signal strength). It can be specified as a position.

[1-5-6] In the above description, the sleeve 70 is provided (sold, etc.) separately from the card 60 , but the sleeve 70 may be provided together with the card 60 . In this case, the sleeve 70 may be provided with the card ID stored in the IC tag 73 (IC chip).

[1-5-7] Card games played by players are not limited to the card games described above. For example, the positions and number of zones Z set in the game field F are not limited to the example shown in FIG. In addition, depending on the card game, there are cases where the area where the card 60 is placed is not limited, such as zones Z1 to Z30, and the player can place the card 60 anywhere in the game field F. FIG. According to the modification shown in FIG. 21, even if the player places the card 60 at any position within the game field F, the position where the card 60 is placed can be identified.

[1-5-8] The game played by the player may be a game played using game media other than the card 60 . For example, the game played by the player may be a game played using game media such as figures, pieces, or tiles, or game media shaped like Go stones.

[1-6. Functional Elements] Functional elements included in the system 1 will be described. FIG. 22 is a functional block diagram for explaining functional elements included in the system 1. As shown in FIG.

[1-6-1] The system 1 is a system related to a game played using an object 100 placed on a target surface, and includes functional elements related to the game.

A “game played using the object 100 placed on the target surface” is, for example, a game progressed by placing the object 100 on the target surface. This is a game in which the type or state (position, orientation, etc.) of the object 100 that has been captured affects the progress or result of the game (win/lose, success, score, etc.). For example, a game in which two players compete by placing play media on the game field corresponds to an example of the above-mentioned "game". For example, the aforementioned card game in which two players compete by placing cards 60 on the game field F is an example of "a game played using an object 100 placed on a target surface." Equivalent to.

The above-mentioned "game" is not limited to a game in which two players compete, and may be a game in which three or more players compete, or a game played by one player. Moreover, the above-mentioned "game" may be a game in which two or more players cooperate to achieve a goal.

A “target surface” is a surface provided in the real world, and is a surface of an object on which the target object 100 is placed. For example, a "object surface" is called a "game field" or a "play field" or the like. The “object surface” may be a flat surface, or may be an uneven surface or a curved surface as long as the object 100 can be placed thereon.

The target object 100 is a real object to be placed on the target surface, and is an object to be used in the game. For example, the object 100 is an object in which a game medium is contained in a container. That is, the target object 100 is a play medium housed in a housing. In other words, the target object 100 is a container containing a game medium. Further, for example, the target object 100 may be the game medium itself (a single game medium).

The "game medium" is, for example, cards, figures, pieces, tiles, and the like. A "game medium" may be an object having a shape like a Go stone.

A "container" is an object capable of containing individual game media. In other words, the "container" is an inserted object into which a game medium can be inserted. A "container" is used to protect the play media. At least a part of the "container" is configured to be transparent, and at least the appearance characteristic portion of the accommodated play media (the portion having the appearance characteristics distinguishable from other play media) is visible from the outside of the containment body. is configured to For example, the "container" is a bag-like object called a "sleeve" or the like.

For example, object 100 includes a writing surface, which is a surface on which information is written. A “writing surface” is a surface on which information about the object 100 is written. For example, information corresponding to the type of object 100 is written on the writing surface. In other words, information unique to the type of object 100 is written on the writing surface. For example, a text, pattern, or the like specific to the type of object 100 is written on the writing surface. The information written on the writing surface can also be said to be information that can be specified from the type of the object 100 .

For example, if the object 100 is a game medium contained in a container (or a single game medium), information about the game medium contained in the container is written on the writing surface. For example, if the object 100 is a card housed in a sleeve (or a single card), the name of the card, its attributes, the details of its influence on the progress or result of the game, or its design are written on the writing surface. be done.

Also, the “written surface” is a surface that allows the type of the target object 100 to be specified from the captured image if this surface appears in the captured image. In other words, the “written surface” is a surface on which information that can specify the type of the target object 100 is written.

Note that the information written on the “writing surface” is not limited to information about the object 100, and may be information about a game.

Further, for example, the object 100 includes a first surface portion and a second surface portion different from the first surface portion. For example, the second side is the side opposite the first side. The angle between the normal direction of the outer surface of the first surface portion and the normal direction of the outer surface of the second surface portion is 180 degrees or approximately 180 degrees. When the object 100 is placed on the target surface so that the outer surface of the first surface portion and the target surface are in contact with each other, the outer surface of the second surface portion faces upward. When the object 100 is placed on the target surface so that the and the target surface are in contact with each other, the outer surface of the first surface faces upward. have.

When the target object 100 is an object in which a game medium is contained in a container, the container includes a first surface portion and a second surface portion, and the game medium includes a writing surface. The inner side surface of the first surface portion and the inner side surface of the second surface portion face each other when the game medium is not stored in the container, and the first surface portion (the inner surface of the first surface portion) is opposed to the inner surface of the second surface portion when the game medium is stored in the container. side) and the writing surface of the game object face each other. For example, all or part of the first surface portion is formed using a transparent material (transparent film, etc.), and the first surface portion allows the writing surface of the game object housed in the container to be viewed from outside the container to the first surface. It is configured to be visible through the surface portion. When the game medium is a card, when the card is accommodated in the container, the inner side surface of the first surface portion and the first surface of the card (for example, the surface/writing surface) face each other, and the inner surface of the second surface portion and the card are opposed to each other. The second surface (for example, the back surface) of the .

As shown in FIG. 22, the object 100 includes a holding portion 101. As shown in FIG. The holding unit 101 is for holding specific information as described below. For example, the holding portion 101 is provided on a surface different from the surface described above. That is, the object 100 includes the above-described writing surface and a holding surface that is a surface provided with the holding portion 101 .

For example, the identification information is information for identifying the type or state of the object 100 placed on the object plane. That is, the identification information is basic information for identifying at least one of the type and state of the object 100 placed on the object plane. In other words, the identification information includes at least one of information serving as a basis for identifying the type of the object 100 and information serving as a basis for identifying the state of the object 100 . Note that the "information serving as a basis for specifying the type of the target object 100" may be information indicating the type of the target object 100 itself (in other words, information identifying the type of the target object 100). Also, the “basic information for specifying the state of the object 100” may be information indicating the state of the object 100 itself.

If the target object 100 is a game medium contained in a container (or a single game medium), the specific information is the game medium placed on the target surface while contained in the container (or the target surface). This is information for specifying the type or state of the game media placed on top. That is, the specific information includes basic information for specifying the type of game medium (or single game medium) contained in the container, and the state of the game medium (or single game medium) contained in the container. and/or information serving as a basis for identification.

There is data that associates a container ID, which is identification information for uniquely identifying a container, with a game medium ID, which is identification information for uniquely identifying the type of game media contained in the container, and If the type of game media contained in a container can be identified based on the ID, the container ID is an example of "basic information for identifying the type of game medium contained in the container." corresponds to Note that identification information that uniquely identifies the holding unit 101 can be used as the container ID. For example, when the holding unit 101 is an IC tag, a tag ID, which is identification information that uniquely identifies each IC tag, can be used as the container ID.

Information indicating the type of game media contained in the container itself (in other words, information identifying the type of game medium) is also referred to as "information serving as a basis for identifying the type of game medium contained in the container." ” can correspond to an example. Specifically, the game medium ID, which is identification information that uniquely identifies the type of game medium, can also correspond to an example of "basic information for identifying the type of game medium contained in the container".

Further, for example, the identification information is information for identifying information written on the writing surface of the target object 100 placed on the target surface. That is, the identification information is information serving as a basis for identifying information written on the writing surface of the object 100 placed on the object surface. For example, if the information written on the writing surface is information related to the type of the object 100, and if the type of the object 100 is specified, the information written on the writing surface can be specified. Information serving as a basis for specifying corresponds to "information serving as a basis for specifying information written on the writing surface of the object 100".

In the card game described above, the game field F (in other words, the mat 12) corresponds to an example of the "target surface". Also, the card 60 corresponds to an example of a "game medium", and the sleeve 70 corresponds to an example of a "container". A card 60S in which the card 60 is accommodated in a sleeve provided with the IC tag 73 corresponds to an example of the object 100. FIG. Further, the surface portion 71 and the back surface portion 72 of the sleeve 70 correspond to examples of the "first surface portion" and the "second surface portion", respectively. Furthermore, the front surface 61 of the card 60S corresponds to an example of the "writing surface", and the inner surface of the back surface portion 72 of the sleeve 70 corresponds to an example of the "holding surface".

Also, the IC tag 73 of the card 60S corresponds to an example of the holding portion 101. FIG. The tag ID corresponds to an example of "specific information held in the holding unit 101" (information serving as a basis for specifying the type of game media contained in the container). Note that when the association process shown in FIG. 12 is executed, the card ID written in the IC tag 73 is the "specific information held in the holding unit 101" (the type of game media contained in the container). basic information for identification).

In the case of the modification shown in FIG. 20, a card 60S in which an object 80 having an IC tag 73 and a card 60 are housed in a sleeve 70 corresponds to an example of the object 100. The IC tag 73 that is attached corresponds to an example of the holding unit 101 . Further, in the case of the modification in which the card 60 itself has the IC tag 73 , the card 60 itself corresponds to an example of the object 100 and the IC tag 73 provided on the card 60 corresponds to an example of the holding portion 101 .

[1-6-2] The system 1 displays functional elements for identifying the type and state of the target object 100 placed on the target plane, and displays related to the target object 100 placed on the target plane. 1 includes a photographing unit 110 , a captured image acquiring unit 120 , a reading unit 130 , a reading result acquiring unit 140 , a specifying unit 150 , and a display control unit 160 .

[1-6-3] The photographing unit 110 photographs the object plane on which the object 100 is placed. For example, the photographing unit 110 photographs the target plane from above the target plane. The photographing unit 110 may be capable of photographing the entire target plane, or may be capable of photographing only a region of the target plane where the target object 100 may be placed. In this embodiment, the imaging device 30 corresponds to the imaging unit 110 .

[1-6-4] The reading unit 130 reads information held by the holding unit 101 of the object 100 placed on the object surface.

The target object 100 includes a writing surface on which information is written and a holding surface which is a surface provided with the holding unit 101. The reading unit 130 reads the object surface so that the writing surface and the object surface face each other. It is possible to read information held in the holding portion 101 of the holding surface of the object placed thereon.

For example, the holding unit 101 is an IC tag, and the reading unit 130 reads information stored in the IC tag. That is, the reading unit 130 includes one or more IC tag readers. For example, the reading unit 130 includes a plurality of IC tag readers installed at a plurality of positions respectively corresponding to a plurality of positions on the target surface. Further, for example, the reading unit 130 includes an IC tag reader having an antenna arranged to pass through a plurality of positions on the target surface. In other words, the reading unit 130 includes a plurality of antennas that receive signals transmitted from IC tags, and includes a plurality of antennas installed so as to correspond to a plurality of positions on the target surface. It reads information stored in the provided IC tag. In this embodiment, the reading devices 20-1 to 20-30 installed corresponding to the plurality of zones Z1 to Z30 of the game field F correspond to the reading section . In the case of the modification shown in FIG. 21, the antennas (the first antenna 21 and the second antenna 22) are arranged so as to pass through a plurality of positions corresponding to the plurality of positions on the game field F. corresponds to the reading unit 130 .

In the example of the card game described above, the IC tag 73 of the sleeve 70 corresponds to an example of the holding portion 101, the surface 61 of the card 60 accommodated in the sleeve 70 corresponds to an example of the "writing surface", and the sleeve 70 The inner surface of the back surface portion 72 corresponds to an example of the "holding surface".

In the case of the card game example described above, the reading unit 130 reads the tag ID (an example of information for identifying the holding unit 101) stored in the IC tag 73 of the card 60S placed in the game field F.

Note that when the association process shown in FIG. 12 is executed, the card ID of the card 60S (an example of information for identifying the type of the object 100) is stored in the IC tag 73 of the card 60S. The unit 130 reads the card ID stored in the IC tag 73 of the card 60S placed on the game field F.

[1-6-5] The photographed image obtaining unit 120 obtains the photographed image of the photographing unit 110 . The reading result acquisition unit 140 acquires the reading result of the reading unit 130 . The specifying unit 150 specifies the type and state of the target object 100 placed on the target surface based on the captured image of the capturing unit 110 and the reading result of the reading unit 130 . For example, the captured image acquisition unit 120 , the reading result acquisition unit 140 , and the identification unit 150 are realized by the control unit 41 of the information processing device 40 .

To "identify the type of the target object 100" is to specify which of a plurality of types of the target object 100 the target object 100 placed on the target surface is. That is, one or a plurality of target objects 100 out of a plurality of types of target objects 100 can be placed on the target plane, and at least one of the target objects 100 placed on the target plane is a target object of a plurality of types. Specifying which of the objects 100 is equivalent to "identifying the type of the target object 100". For example, each target object 100 is assigned identification information that identifies the type of the target object 100, and identifying the identification information of the target object 100 placed on the target surface is "identifying the type of the target object 100". Equivalent to "specify". If the object 100 is a game medium contained in a container, identifying the type (identification information) of the game medium contained in the container corresponds to "identifying the type of the object 100". .

"Identifying the state of the object 100" includes, for example, identifying the position of the object 100 placed on the object plane.

Further, "identifying the state of the object 100" includes, for example, specifying the placement method (arrangement format) of the object 100 placed on the object plane. Specifically, identifying the orientation of the object 100 placed on the object surface corresponds to an example of "identifying the state of the object 100". The “orientation” of the object 100 is the direction in which the reference direction of the object 100 faces.

For example, when the target object 100 is a rectangular object, the long side direction of the target object 100 corresponds to an example of the “reference direction”. In this case, identifying which direction the long side of the object 100 faces corresponds to an example of "identifying the orientation of the object 100". For example, the object 100 is placed with the long side direction of the object 100 facing the first direction, or the object 100 is placed with the long side direction of the object 100 facing the second direction. Specifying whether the object 100 is facing corresponds to an example of "identifying the orientation of the object 100". More specifically, the target object 100 is placed in a vertical state (a state in which the object 100 appears vertically long when viewed from a specific viewpoint (player or the imaging unit 110)), or the target object 100 is in a horizontal state (a specific position). Specifying whether the object 100 is placed in a state in which the object 100 appears horizontally when viewed from the viewpoint corresponds to an example of "specifying the orientation of the object 100".

Also, for example, the normal direction of a specific plane (surface or the like) of the target object 100 corresponds to an example of the “reference direction”. In this case, specifying which direction the normal direction of the specific surface (surface or the like) of the card faces corresponds to an example of "specifying the orientation of the object 100". For example, it is possible to specify whether the target object 100 is placed with the normal direction facing the first direction or whether the target object 100 is placed with the normal direction facing the second direction. This corresponds to an example of "identifying the orientation of the object 100". More specifically, the object 100 is placed with its front side facing up (a state in which the front side can be seen from a specific viewpoint), or with its back side facing up (a state in which the back side can be seen from a specific viewpoint: Specifying whether the object 100 is placed upside down corresponds to an example of "specifying the orientation of the object 100".

Further, for example, when the target object 100 is a figure housed in a container or a single figure, the front direction of the figure corresponds to an example of the “reference direction”. In this case, identifying which direction the figure faces is an example of "identifying the orientation of the object 100".

If the object 100 is a game medium stored in a container, identifying the state of the game medium contained in the container corresponds to "identifying the state of the object 100".

In addition, the “state of the object 100” specified by the specifying unit 150 is, among the items that can be included in the phrase “state of the object 100”, items that affect the progress or result of the game. In other words, the “state of the object 100” specified by the specifying unit 150 means, among the items that can be included in the wording “state of the object 100”, items that are meaningful in the course of the game, and display unit 170. This is an important matter for the viewer.

For example, the specifying unit 150 specifies some items based on the captured image of the imaging unit 110 among items related to the type and state of the object 100 placed on the target surface, and specifies other items based on the image captured by the reading unit 130 . based on the reading result of

[1-6-6] As shown in FIG. 22 , the identification unit 150 includes a first identification unit 151 and a second identification unit 152 .

[1-6-6-1] The first specifying unit 151 specifies the position of the target object 100 placed on the target plane based on the captured image of the imaging unit 110 . Also, the first identifying unit 151 identifies the orientation of the target object 100 placed on the target surface based on the image captured by the imaging unit 110 .

For example, the first identifying unit 151 may perform machine learning based on learning data including photographed image data of the target surface on which the target object 100 is placed and correct data indicating the position and orientation of the target object 100. Identifying the position and orientation of the object 100 in the captured image using the trained model generated by (a model for identifying the position and orientation of the object 100 in the captured image) identifies the position and orientation of the object 100 placed on the object plane.

Further, for example, the first identifying unit 151 identifies the position and orientation of the target object 100 placed on the target plane by detecting the target object 100 from the captured image of the imaging unit 110 using image analysis processing. may That is, the first specifying unit 151 detects the target object 100 from the captured image based on the feature information of the appearance of the target object 100, thereby specifying the position and orientation of the target object 100 appearing in the captured image. may identify the position and orientation of the object 100 placed on the object plane.

In the case of the card game example described above, the first identification unit 151 identifies the position of the card 60S based on the captured image of the imaging device 30 . Also, the first identifying unit 151 identifies the vertical and horizontal orientation of the card 60S based on the captured image of the imaging device 30 . Also, the first identification unit 151 identifies the orientation of the front and back of the card 60S based on the photographed image of the photographing device 30 .

[1-6-6-2] The second specifying unit 152 specifies the position of the target object 100 placed on the target surface based on the reading result of the reading unit 130 . Also, the second identifying unit 152 identifies the type of the target object 100 placed on the target surface based on the reading result of the reading unit 130 . Also, the second specifying unit 152 specifies information written on the writing surface of the target object 100 placed on the target surface based on the reading result of the reading unit 130 . For example, the second identifying unit 152 identifies information written on the writing surface of the target object 100 placed on the target surface based on the result of specifying the type of the target object 100 placed on the target surface.

The “reading result of the reading unit 130 ” is information read by the reading unit 130 . Also, the “reading result of the reading unit 130” may be information as to whether or not the information held in the holding unit 101 could be read.

The holding unit 101 is an IC tag, and the reading unit 130 is an antenna for receiving signals transmitted from the IC tag, and a plurality of antennas are installed so as to correspond to a plurality of positions on the target surface. When included, the "reading result of the reading unit 130" is information as to which of the plurality of antennas received the signal transmitted from the IC tag of the object placed on the object surface. good. For example, when the reading unit 130 includes a plurality of IC tag readers installed at a plurality of positions respectively corresponding to a plurality of positions on the target surface, the "reading result of the reading means" means that the information stored in the IC tag is It may be information as to which IC reader among a plurality of IC readers has read. Further, for example, when the reading unit 130 includes an IC tag reader having an antenna arranged to pass through a plurality of positions on the target surface, the "reading result of the reading means" means that the signal from the IC tag is It may be information about which part it was received.

In the case of the card game example described above, the information read by the reader 20 (the information stored in the IC tag 73) corresponds to an example of the "read result of the reading unit 130". Information as to whether or not the reading device 20 has read the information stored in the IC tag 73 is also an example of the "reading result of the reading unit 130". In addition, it is determined by which of the plurality of readers 20-1 to 20-30 the information stored in the IC tag 73 was read (in other words, the signal from the IC tag 73 is read by the plurality of readers 20-1 to 20-30). 20-30) is also an example of the "reading result of the reading unit 130". In the case of the modification shown in FIG. 21, the information as to which first antenna 21 and second antenna 22 received the signal from the IC tag 73 corresponds to an example of the "reading result of the reading unit 130".

In the case of the card game example described above, the second specifying unit 152 specifies the position and type of the card 60S placed on the game field F based on the reading result of the reading device 20 .

For example, the second identifying unit 152 identifies the position of the card 60S based on which reader 20 read the information stored in the IC tag 73 of the card 60S. That is, the second specifying unit 152 corresponds to the position of the reader 20 that read the information stored in the IC tag 73 of the card 60S (the reader 20 that received the signal transmitted from the IC tag 73 of the card 60S). The position of the card 60S on the game field F is specified as the position of the card 60S. For example, when the information stored in the IC tag 73 of the card 60S is read by the reader 20-10, the second identification unit 152 identifies the zone Z10 associated with the reader 20-10 as the card 60S is located. Identify zone Z as the cut zone.

In the case of the modification shown in FIG. 21, the second specifying unit 152 determines the position of the card 60S based on which part of the antenna received the signal from the IC tag 73 of the card 60S. may be specified. That is, the second specifying unit 152 may specify, as the position of the card 60S, the position on the game field F corresponding to the portion of the antenna where the signal from the IC tag 73 of the card 60S is received. For example, the second identifying unit 152 detects the first antenna 21 and the second antenna 22 that have received the signal from the IC tag 73 of the card 60S (in other words, the first antenna 21 and the second antenna 22 with the strongest received signal strength). may be specified as the zone Z in which the card 60S is placed.

Also, the second specifying unit 152 specifies the type of the card 60S placed on the game field F based on the information read by the reading device 20 .

For example, when the association processing shown in FIG. 10 is executed, the association data D1 (FIG. 11) that associates the tag ID and the card ID is stored in the storage unit 42 . In this case, the second identification unit 152 identifies the card ID associated with the tag ID read by the reader 20 based on the association data D1.

Further, for example, when the association process shown in FIG. 12 is executed, the card ID of the card 60S is stored in the IC tag 73 of the card 60S, and the card ID is read by the reading unit 130. FIG. In this case, the second identification unit 152 acquires the card ID read by the reader 20 .

[1-6-6-3] A plurality of objects 100 may be placed on the object plane. In this case, the identification result of the first identification unit 151 based on the captured image of the imaging unit 110 is obtained for each of the plurality of objects 100 . Similarly, the identification result of the second identification unit 152 based on the reading result of the reading unit 130 is also obtained for each of the plurality of objects 100 . In such a case, it is necessary to specify a combination of the identification result of the first identification unit 151 and the identification result of the second identification unit 152 regarding the same target object 100 placed on the target plane.

In this regard, the identification result of the first identification unit 151 and the identification result of the second identification unit 152 commonly include the identification result regarding the predetermined item of the object 100, and the identification unit 150 is the first identification unit 151 and the identification result of the second identification unit 152, the identification result of the first identification unit 151 regarding the same target object 100 placed on the target surface is collated. A combination of the identification result and the identification result of the second identification unit 152 is identified.

In the present embodiment, since the identification result regarding the position of the target object 100 (an example of the predetermined item) is commonly included in the identification result of the first identification unit 151 and the identification result of the second identification unit 152, the identification unit A reference numeral 150 denotes the identification result of the first identification unit 151 regarding the same target object 100 placed on the target plane based on the position identified by the first identification unit 151 and the position identified by the second identification unit 152. and the identification result of the second identification unit 152 are identified.

That is, the specifying unit 150 compares the position specified by the first specifying unit 151 and the position specified by the second specifying unit 152, and compares the position specified by the first specifying unit 151 and the position specified by the second specifying unit 152. A specified result is specified as a specified result for the same target object 100 placed on the target plane.

In other words, when the position identified by the first identification unit 151 and the position identified by the second identification unit 152 correspond, the identification unit 150 identifies the type identified by the first identification unit 151 and the second identification unit 151 . It is determined that the combination with the orientation identified by the unit 152 is the identification result for the same object 100 placed on the object plane.

“When the position specified by the first specifying unit 151 and the position specified by the second specifying unit 152 correspond” means that the position specified by the first specifying unit 151 and the position specified by the second specifying unit 152 correspond to each other. For example, the position specified by the first specifying unit 151 and the position specified by the second specifying unit 152 both correspond to the same region. It can be rephrased as a case or the like.

For example, in the example of the card game described above, a plurality of zones Z1 to Z30 (partial areas) are defined within the game field F as areas for placing cards 60S, and a plurality of readers 20-1 to 20-30 are provided. are installed so as to correspond to a plurality of zones Z1 to Z30. When the card 60S is placed in any zone Z, the zone Z in which the card 60 is placed can be specified from the photographed image of the photographing device 30. FIG. Apart from that, the zone Z in which the card 60 is placed can also be specified from the reading result of the reading device 20 . That is, the zone Z corresponding to the reader 20 that has read the information stored in the IC tag 73 of the card 60S is specified as the zone Z where the card 60S is placed. In such a case, "the case where the position specified by the first specifying unit 151 corresponds to the position specified by the second specifying unit 152" means the zone Z specified from the captured image of the imaging device 30, This is the case where the zone Z identified from the reading result of the reading device 20 is the same.

Note that “when the position specified by the first specifying unit 151 corresponds to the position specified by the second specifying unit 152” means the position specified from the captured image of the imaging unit 110 and the position specified by the reading unit 130. It may be the case that the distance to the position specified from the reading result is less than the threshold.

[1-6-6-4] Note that the second specifying unit 152 determines the type of the card 60S (first card) placed on the game field F with the other cards 60S (second card) stacked. can be specified based on the information read by the reading unit 130 from the IC tag 73 of the card 60S (first card). For example, even when card bundle 600-1 is placed in zone Z7 as in the situation shown in FIG. Each type can be identified based on information read by the reading unit 130 from the IC tag 73 of each of the plurality of cards 60S.

[1-6-7] The display control unit 160 causes the display unit 170 to display an object corresponding to the target object 100 placed on the target plane. For example, the display control unit 160 is realized by at least one of the control unit 41 of the information processing device 40 and the control unit 51 of the display terminal device 50 . The display unit 170 is implemented by at least one of the display unit 45 of the information processing device 40 and the display unit 55 of the display terminal device 50 .

An “object” is what is displayed on the display unit 170 . For example, an “object” is an object imitating the target object 100 . In other words, an “object” is an image of the object 100 . The “object” may be an object (text, icon, etc.) that indicates the type or name of the target object 100, or the content of the effect on the progress or result of the game.

For example, the display control unit 160 causes the display unit 170 to display an object corresponding to the type of the target object 100 specified by the specifying unit 150 in a state corresponding to the state of the target object 100 specified by the specifying unit 150 . Specifically, the display control unit 160 causes the object corresponding to the type of the target object 100 specified by the specifying unit 150 to correspond to the position of the target object 100 specified by the specifying unit 150 (position on the target plane). Display at the display position. Also, the display control unit 160 displays an object corresponding to the type of the target object 100 specified by the specifying unit 150 in an orientation corresponding to the orientation of the target object 100 specified by the specifying unit 150 .

Further, for example, the display control unit 160 causes the display unit 170 to display an object corresponding to the type of the target object 100 specified by the specifying unit 150 according to the state of the target object 100 specified by the specifying unit 150 .

Specifically, according to the state of the target object 100 specified by the specifying unit 150, the display control unit 160 selects the type of the target object 100 specified by the specifying unit 150 as an object corresponding to the target object 100. It is determined whether or not to display the object to be displayed on the display unit 170 .

That is, the display control unit 160 determines whether the state of the object 100 specified by the specifying unit 150 is a predetermined state. Then, when it is determined that the state of the target object 100 specified by the specifying unit 150 is not the predetermined state, the display control unit 160 selects the target object specified by the specifying unit 150 as an object corresponding to the target object 100. Objects corresponding to 100 types are displayed on the display unit 170 . On the other hand, when it is determined that the state of the target object 100 specified by the specifying unit 150 is in the predetermined state, the display control unit 160 selects the object specified by the specifying unit 150 as an object corresponding to the target object 100. An object corresponding to the type of the object 100 is not displayed on the display unit 170. - 特許庁In this case, the display control unit 160 causes the display unit 170 to display, as an object corresponding to the target object 100 , an object that does not depend on the type of the target object 100 specified by the specifying unit 150 .

In addition, when the object 100 is placed on the target surface such that the above-described writing surface (surface on which information is written) of the object 100 and the target surface are opposed to each other, the display control unit 160 performs the identification The display unit 170 is caused to display a display corresponding to the information written on the writing surface of the object 100 specified by the unit 150 (second specifying unit 152).

“When the object 100 is placed on the object surface so that the writing surface and the object surface face each other” means that the object 100 is placed on the object surface so that the writing surface is not visible from the imaging unit 110. is placed.

For example, when the object 100 is a game medium housed in a container, "when the object 100 is placed on the object surface so that the writing surface and the object surface face each other" This is the case where the target object 100 is placed on the target surface so that the writing surface of the game medium and the target surface face each other through the container. In other words, this is the case where the object 100 is placed on the target surface such that the writing surface and the target surface of the game medium are in contact with each other via the container.

When the target object 100 is a single game medium, "when the target object 100 is placed on the target surface so that the writing surface and the target surface face each other" means the writing surface of the game medium. The object 100 (game medium) is placed on the target surface so that the .

“Displaying on the display unit 170 a display corresponding to the information written on the writing surface” means, for example, causing the display unit 170 to display the information written on the writing surface of the target object 100 . In this case, all of the information written on the writing surface may be displayed on the display unit 170, or part of the information written on the writing surface may be displayed on the display unit 170. FIG.

Specifically, “to cause the display unit 170 to display a display corresponding to the information written on the writing surface” means to cause the display unit 170 to display an object simulating the writing surface of the target object 100 . In other words, it is to cause the display unit 170 to display an object formed by imaging the writing surface of the target object 100 .

For example, when the type of the target object 100 or the content of the effect on the progress or result of the game is written on the writing surface, "Display on the display unit 170 a display corresponding to the information written on the writing surface. ” may refer to displaying on the display unit 170 a text, a pattern, or the like indicating the type of the object 100 or the details of the effect on the progress or result of the game. In this case, the method of displaying the type of the object on the display unit 170 or the details of the effect on the progress or result of the game may be different from the method of displaying on the writing surface.

Further, for example, when the type of the target object 100 is written on the writing surface, "displaying on the display unit 170 a display corresponding to the information written on the writing surface" is a matter not written on the writing surface. Alternatively, the display unit 170 may be caused to display a text, a pattern, or the like indicating matters specified by the type of the object 100 (for example, the content of the influence that the object 100 has on the progress or result of the game).

It should be noted that "to cause the display unit 170 to display a display corresponding to the information written on the writing surface" means that the display corresponding to the information written on the writing surface is displayed on the writing surface by transmitting data related to the display corresponding to the information written on the writing surface to another device. may be displayed on the display unit 170 of the other device according to the information described in .

At least when the object 100 is placed on the target surface such that the writing surface and the target surface face each other, the display control unit 160 determines whether the object specified by the specifying unit 150 (second specifying unit 152) is displayed. The display section 170 is caused to display a display corresponding to the information written on the writing surface of the object 100 .

The display control unit 160 controls the display when the target object 100 is placed on the target surface so that the writing surface and the target surface do not face each other (that is, when the target object 100 is placed on the target surface while the writing surface is visible). ), the display unit 170 may display a display corresponding to the information written on the writing surface of the target object 100 specified by the specifying unit 150 (second specifying unit 152). In such a case, the display unit 170 may display a display corresponding to the information written on the writing surface of the object 100 specified by another specifying method. For example, when the target object 100 is placed on the target surface so that the writing surface and the target surface do not face each other (that is, when the target object 100 is placed on the target surface with the writing surface visible). Alternatively, the information written on the writing surface of the target object 100 may be read, and a display corresponding to the read information may be displayed on the display unit 170 . For example, when the target object 100 is placed on the target surface in a state in which the writing surface is captured in the captured image of the imaging unit 110, the information written on the writing surface of the target object 100 is obtained from the captured image of the imaging unit 110. The information may be specified, and the display unit 170 may display a display corresponding to the information specified in this way.

Further, the display control unit 160 receives a predetermined operation regarding an object corresponding to the target object 100 in a state in which the target object 100 is placed on the target surface so that the writing surface and the target surface face each other. In this case, the display unit 170 may display a display corresponding to the information written on the writing surface of the object 100 .

A “predetermined operation” is, for example, an operation of designating (or selecting) an object. The 'predetermined operation' may be an operation for specifying any of the objects, and may be an operation for specifying the type, position, or orientation of the object. Based on such manipulation, an object corresponding to the specified type, position, or orientation is identified. For example, based on such an operation, a process of displaying on the display unit 170 the display according to the information written on the writing surface of the object 100 corresponding to the object is executed.

In the case of the card game example described above, each of the parts PB-1 and PB-2 shown in FIG. 8 corresponds to an example of the "object", and the part PC shown in FIG. It corresponds to an example of "display according to In the case of the card game example described above, the display control unit 160 causes the display unit 170 to display the game field image G. FIG.

For example, the display control unit 160 determines whether the orientation of the card 60S specified by the first specifying unit 151 is face up or face down.

Then, when the orientation of the card 60S specified by the first specifying unit 151 is face up, the display control unit 160 selects the part PB-2 shown in FIG. The image of the surface 61 of the card 60S (that is, the image corresponding to the type of the card 60S specified by the second specifying unit 152) is displayed at the position of the card 60S specified by the first specifying unit 151 or the second specifying unit 152. is displayed at a position in the game field image G corresponding to .

On the other hand, when the orientation of the card 60S specified by the first specifying unit 151 is face down, the display control unit 160 selects the part PB-2 shown in FIG. The image of the surface 61 of the card 60S (that is, the image corresponding to the type of the card 60S specified by the second specifying unit 152) is not displayed, and instead, the part PB-1 shown in FIG. 8 is displayed. , the image of the back surface 62 of the card 60S (that is, the image regardless of the type of the card 60S specified by the second specifying unit 152) is the card specified by the first specifying unit 151 or the second specifying unit 152. It is displayed at a position within the game field image G corresponding to the position of 60S.

In addition, the display control unit 160 controls the part indicating the front side 61 of the card 60S in response to the operation of specifying a part associated with the card 60S placed face down, such as the part PB-1 shown in FIG. Display PC.

[2. Second Embodiment] A second embodiment of the present invention will be described.

The second embodiment differs from the first embodiment in that the card orientation (vertical and horizontal orientation) is specified based on information stored in the IC tag. Differences from the first embodiment will be described below. Below, the same reference numerals are used for the same elements as those of the first embodiment, and the description thereof is omitted.

[2-1. Outline] FIG. 23 shows an example of the sleeve 70A of the second embodiment. As with the sleeve 70 of the first embodiment, the surface portion 71A of the sleeve 70A is transparent so that the surface 61 of the card 60 housed in the sleeve 70A can be viewed from outside the sleeve 70A. Also, like the sleeve 70 of the first embodiment, the back surface portion 72A of the sleeve 70A is opaque and has an appearance common to all sleeves 70A.

As shown in FIG. 23, the sleeve 70A includes a first IC tag 73A-1 and a second IC tag 73A-2. The first IC tag 73A-1 and the second IC tag 73A-2 are provided on the inner surface of the back surface portion 72A. For example, the installation positions of the first IC tag 73A-1 and the second IC tag 73A-2 on the inner surface of the back surface portion 72A are different. For example, the installation positions of the first IC tag 73A-1 and the second IC tag 73A-2 are the difference in the first direction (for example, vertical direction) between those positions and the difference in the second direction (for example, horizontal direction) between those positions. direction) is set differently.

The tag ID of the first IC tag 73A-1 is stored in the first IC tag 73A-1, and the tag ID of the second IC tag 73A-2 is stored in the second IC tag 73A-2. Since the first IC tag 73A-1 and the second IC tag 73A-2 are separate IC tags, their tag IDs are different from each other.

In the second embodiment, the card 60 is accommodated within the sleeve 70A as described above. Hereinafter, the card 60 housed in the sleeve 70A will be referred to as "card 60SA" for the sake of convenience in order to distinguish it from the card 60 alone. In other words, the card 60 and the sleeve 70A when the card 60 is housed in the sleeve 70A are regarded as one object and described as "card 60SA".

Further, in the second embodiment, the first IC tag 73A-1 and the second IC tag 73A-1 and the second IC tag 73A-2 of the card 60SA placed on the game field F can be identified. 2 IC tag 73A-2, a reader 20 is installed, which is provided with a plurality of antennas that are installed so as to correspond to a plurality of positions on the game field F, respectively. be. For example, in the second embodiment, a reading device 20 having a plurality of first antennas 21 and a plurality of second antennas 22 as shown in FIG. 21 is installed.

That is, when the card 60SA is placed on the game field F, the signal from the first IC tag 73A-1 (the ID tag of the first IC tag 73A-1) is received by the first antenna 21 and the second antenna 22. By specifying the combination (in other words, the combination of the first antenna 21 and the second antenna 22 with the strongest strength of the signal received from the first IC tag 73A-1), the first IC tag 73A-1 on the game field F It is possible to specify the position. For example, the game field F It can be specified as the position of the first IC tag 73A-1 above.

Similarly, the combination of the first antenna 21 and the second antenna 22 that received the signal from the second IC tag 73A-2 (the ID tag of the second IC tag 73A-2) (the intensity of the signal received from the second IC tag 73A-2 The position of the second IC tag 73A-2 on the game field F can be specified by specifying the combination of the first antenna 21 and the second antenna 22 with the strongest .

Here, as shown in FIGS. 24 and 25, a predetermined point (for example, lower left point) of the game field F is the origin O, the horizontal direction of the game field F is the X-axis direction, and the vertical direction of the game field F is the Y-axis direction. Assume a coordinate system with The position of the first IC tag 73A-1 on the game field F is (X1, Y1), and the position of the second IC tag 73A-2 on the game field F is (X2, Y2).

As shown in FIG. 24, when the card 60SA is placed vertically, the long side direction of the card 60SA is parallel (or substantially parallel) to the Y-axis direction, and the card 60SA is vertically long. . In this case, the absolute value of the difference between Y1 and Y2 (|Y1-Y2|) is greater than the absolute value of the difference between X1 and X2 (|X1-X2|). Therefore, when the specified positions of the first IC tag 73A-1 and the second IC tag 73A-2 have a relation of |Y1-Y2|>|X1-X2|, the card 60SA is placed vertically. can be identified.

On the other hand, as shown in FIG. 25, when the card 60SA is placed horizontally, the long side direction of the card 60SA is parallel (or substantially parallel) to the X-axis direction, and the card 60SA is horizontally long. Become. In this case, the absolute value of the difference between X1 and X2 (|X1-X2|) is greater than the absolute value of the difference between Y1 and Y2 (|Y1-Y2|). Therefore, when the specified positions of the first IC tag 73A-1 and the second IC tag 73A-2 have a relationship of |X1-X2|>|Y1-Y2|, the card 60SA is placed horizontally. can be specified.

As described above, in the second embodiment, the positions of the first IC tag 73A-1 and the second IC tag 73A-2 are identified based on the reading result of the reader 20, and the card 60SA is identified based on their positional relationship. can specify the horizontal and vertical orientation of the

[2-2. Processing] Processing executed by the system 1A according to the second embodiment will be described.

[2-2-1] Also in the second embodiment, association processing similar to the association processing shown in FIG. 10 is executed. However, in step S404, the control unit 41 acquires the tag IDs of the first IC tag 73A-1 and the second IC tag 73A-2. Both tag IDs of the second IC tag 73A-2 are registered in the "tag ID" field of the association data D1.

[2-2-2] Also in the second embodiment, association processing similar to the association processing shown in FIG. 12 may be executed. However, in step S424, the control unit 41 writes the card ID specified in step S422 to both the first IC tag 73A-1 and the second IC tag 73A-2.

[2-2-3] Also in the second embodiment, a specific process similar to the specific process shown in FIG. 13 is executed.

In the second embodiment, in step S432, the control unit 41 specifies the position and front/back orientation of the card 60SA, but does not specify the vertical/horizontal orientation of the card 60SA. In this case, the identification result in step S432 is registered in the first identification result data D2A. FIG. 26 shows an example of first identification result data D2A in the second embodiment. As shown in FIG. 26, the first identification result data D2A includes "area ID" and "front/back flag" fields. The "area ID" and "front/back flag" fields are the same as the "area ID" and "front/back flag" fields of the first identification result data D2 of the first embodiment.

Further, in the second embodiment, in step S436, the control unit 41 identifies the card ID, position, and vertical/horizontal orientation of the card 60SA placed on the game field F. FIG.

For example, the control unit 41 refers to the association data D1 to identify the card ID associated with the tag ID read from the first IC tag 73A-1 and the tag ID read from the second IC tag 73A-2.

Further, when the tag ID read from the first IC tag 73A-1 and the ID tag read from the second IC tag 73A-2 are associated with the same card ID, the control unit 41 It is assumed that the tag 73A-1 and the second IC tag 73A-2 are provided on the same card 60SA. Then, the control unit 41 executes the processing described below with respect to the first IC tag 73A-1 and the second IC tag 73A-2 provided on the same card 60SA.

That is, the control unit 41 controls the combination of the first antenna 21 and the second antenna 22 that have received the signal (tag ID) from the first IC tag 73A-1 (in other words, the intensity of the signal received from the first IC tag 73A-1 The position of the first IC tag 73A-1 on the game field F is specified by specifying the combination of the first antenna 21 and the second antenna 22 with the strongest .

Similarly, the control unit 41 controls the combination of the first antenna 21 and the second antenna 22 that have received the signal (tag ID) from the second IC tag 73A-2 (in other words, the combination of the signal received from the second IC tag 73A-2). The position of the second IC tag 73A-2 on the game field F is specified by specifying the combination of the first antenna 21 and the second antenna 22 having the highest strength.

Then, the control unit 41 specifies the midpoint between the position of the first IC tag 73A-1 and the position of the second IC tag 73A-2 as the position of the card 60SA, and determines which zone Z includes the specified position. , the zone Z in which the card 60SA is placed is specified.

Furthermore, the control unit 41 identifies the vertical and horizontal orientation of the card 60SA based on the positional relationship between the positions of the first IC tag 73A-1 and the positions of the second IC tag 73A-2.

For example, when the vertical difference (|Y2-Y1|) between the position of the first IC tag 73A-1 and the position of the second IC tag 73A-2 is greater than the horizontal difference (|X2-X1|) First, the control unit 41 identifies that the card 60SA is placed vertically. On the other hand, when the vertical difference (|Y2-Y1|) between the position of the first IC tag 73A-1 and the position of the second IC tag 73A-2 is smaller than the horizontal difference (|X2-X1|) First, the control unit 41 identifies that the card 60SA is placed horizontally.

In the second embodiment, the identification result in step S436 is registered in the second identification result data D3A. FIG. 27 shows an example of the second identification result data D3A. As shown in FIG. 27, the second identification result data D3A includes "zone ID", "card ID", and "vertical/horizontal flag" fields. The "zone ID" field is the same as the "zone ID" field of the game field situation data D4 of the first embodiment. The "card ID" field is the same as the "card ID" field of the second identification result data D3 of the first embodiment. The "vertical and horizontal flag" field is the same as the "vertical and horizontal flag" field of the first identification result data D2 of the first embodiment.

Also, in the second embodiment, in step S438, the control section 41 generates the game field situation data D4 based on the first identification result data D2A and the second identification result data D3A. The game field situation data D4 is the same as in the first embodiment. Further, the process of step S438 is similar to that of the first embodiment, except that the vertical/horizontal flag registered in the "vertical/horizontal flag" field of the second identification result data D3A is registered in the "vertical/horizontal flag" field of the game field situation data D4. is the same as step S438 of .

[2-2-4] Also in the second embodiment, the display control process shown in FIG. 18 and the process shown in FIG. 19 are executed.

[2-3. Effect] According to the second embodiment, the vertical and horizontal orientation of the card 60SA placed on the game field F can be specified based on the reading result of the reading device 20. FIG.

[2-4. Modification] A modification of the second embodiment will be described.

[2-4-1] In the embodiments described above, the installation positions of the first IC tag 73A-1 and the second IC tag 73A-2 are not limited to the example shown in FIG. As for the installation positions of the first IC tag 73A-1 and the second IC tag 73A-2, if the positions of the first IC tag 73A-1 and the second IC tag 73A-2 of the card 60SA placed on the game field F can be specified, The positional relationship may be set so that the vertical and horizontal orientations of the card 60SA can be identified from the positional relationship.

For example, the first IC tag 73A-1 may be placed at the top left position on the back surface portion 72A, and the first IC tag 73A-2 may be placed at the top right position on the back surface portion 72A. Further, for example, the first IC tag 73A-1 may be placed at the upper left position on the back surface portion 72A, and the first IC tag 73A-2 may be placed at the lower left position on the back surface portion 72A.

[2-4-2] In addition to the first IC tag 73A-1 and the second IC tag 73A-2, one or a plurality of IC tags may be installed on the back surface portion 72A. That is, three or more IC tags may be installed on the back surface portion 72A, and the vertical and horizontal orientations of the card 60SA may be specified based on the positional relationship of the three or more IC tags.

[2-4-3] Also in the second embodiment, in step S432, the control section 41 may specify the vertical and horizontal orientation of the card 60SA. That is, the control unit 41 may specify the vertical and horizontal orientation of the card 60SA from the photographed image of the imaging device 30 and may also identify the vertical and horizontal orientation of the card 60SA from the reading result of the reading device 20 . In this case, the identification result of the vertical and horizontal orientation obtained from the photographed image of the photographing device 30 and the identification result of the vertical and horizontal orientation obtained from the reading result of the reading device 20 are collated to obtain the identification result of the vertical and horizontal orientation. You may make it raise the precision of.

[2-4-4] In the embodiment described above, the sleeve 70A (back surface portion 72A) includes the first IC tag 70A-1 and the second IC tag 70A-2. , may be provided with a first IC tag 70A-1 and a second IC tag 70A-2. In this case, the sheet-shaped object and the card 60 accommodated in the sleeve 70A correspond to the card 60SA.

[2-4-5] The card 60 itself (for example, the back surface 62) may be provided with the first IC tag 70A-1 and the second IC tag 70A-2.

[2-5. Functional Elements] FIG. 28 is a functional block diagram for explaining functional elements included in the system 1A according to the second embodiment. Note that FIG. 28 shows functional elements that are the same as the functional elements of the first embodiment (imaging unit 110, captured image acquiring unit 120, reading unit 130, reading result acquiring unit 140, display control unit 160, and display unit 170). are given the same reference numerals as in FIG. 22, and the description of these functional elements is omitted here, and the target object 100A and the specifying unit 150A will be described. Also, with respect to the description of wording, the description of points that overlap with the first embodiment will be omitted.

[2-5-1] First, the object 100A will be described. Here, differences between the target object 100A and the target object 100 in the first embodiment will be described.

The target object 100A includes a first holding portion 101A and a second holding portion 102A provided so as to have a predetermined positional relationship with the first holding portion 101A. If the positions of the first holding part 101A and the second holding part 102A of the object 100A placed on the object surface can be specified, the object 100A can be moved from those positions. It has a positional relationship that can specify the orientation. For example, when the object 100A is placed on the object surface in the first orientation, the positional relationship between the first holding portion 101A and the second holding portion 102A on the object surface becomes the first positional relationship, and the object 100A When placed on the target surface in a second orientation different from the first orientation, the positional relationship between the first holding portion 101A and the second holding portion 102A on the target surface is a second positional relationship different from the first positional relationship. The positions of the first holding portion 101A and the second holding portion 102A on the object 100A are set so as to have a positional relationship.

Specific information for specifying the type or state of the target object 100A placed on the target surface is held in the first holding unit 101A and the second holding unit 102A. Information held in the first holding unit 101A and the second holding unit 102A is read by the reading unit 130 . In this embodiment, the first IC tag 73A-1 corresponds to the first holding portion 101A, and the second IC tag 73A-2 corresponds to the second holding portion 102A.

[2-5-2] The identification unit 150A will be described. The identifying portion 150A includes a first identifying portion 151A and a second identifying portion 152A.

The first identifying unit 151A identifies the position and orientation of the target object 100A based on the image captured by the imaging unit 110. FIG. For example, the first identifying unit 151A identifies the position and front/back orientation of the target object 100A in the same manner as the first identifying unit 151 of the first embodiment.

Second identifying unit 152A identifies the position, type, and orientation of object 100A based on the reading result of reading unit 130 .

152 A of 2nd identification parts identify the kind of 100 A of target objects similarly to the 2nd identification part 152 of 1st Embodiment.

As described above, in the second embodiment, the reading unit 130 reads signals transmitted from each of the first holding unit 101A (first IC tag 73A-1) and the second holding unit 102A (second IC tag 73A-2). and is provided with a plurality of antennas (a plurality of first antennas 21 and a plurality of second antennas 22) installed so as to correspond to a plurality of positions on the game field F, respectively.

The second specifying unit 152A is transmitted from each of the first holding unit 101A (first IC tag 73A-1) and the second holding unit 102A (second IC tag 73A-2) of the object 100A placed on the object plane. The position and orientation of the object 100A placed on the object plane are identified based on which of the plurality of antennas received the signal received.

In order to distinguish whether the signal received by the antenna is transmitted from the first holding unit 101A or the second holding unit 102A, the first holding unit 101A and the second holding unit 102A The information held in each includes different information, and the signals transmitted from each of the first holding unit 101A and the second holding unit 102A contain different information. For example, the identification information of the first holding unit 101A (the tag ID of the first IC tag 73A-1) is held in the first holding unit 101A (the first IC tag 73A-1), and the identification information of the second holding unit 102A (the second IC tag 73A-1). tag ID of the tag 73A-2) is held in the second holding unit 102A (second IC tag 73A-2).

[2-5-3] In the case of the aforementioned card game example, the card 60SA corresponds to the object 100A. In addition, in the case of the modification in which the card 60 itself includes the first IC tag 73A-1 and the second IC tag 73A-2, the card 60 alone corresponds to the object 100A.

The second identification unit 152A receives the signal (tag ID of the first IC tag 73A-1) from the first IC tag 73A-1 of the card 60SA placed on the game field F. The position of the first IC tag 73A-1 on the game field F is specified by specifying the combination (the combination of the first antenna 21 and the second antenna 22 with the strongest signal strength received from the first IC tag 73A-1). do. Similarly, the second identification unit 152A receives the signal (tag ID of the second IC tag 73A-2) from the second IC tag 73A-2 of the card 60SA placed on the game field F, and the first antenna 21 and the second IC tag 73A-2. By specifying the combination of the two antennas 22 (the combination of the first antenna 21 and the second antenna 22 with the strongest strength of the signal received from the second IC tag 73A-2), the second IC tag 73A-2 on the game field F Also specify the position of Then, the second specifying unit 152A specifies the vertical and horizontal orientation of the card 60SA based on the positional relationship between the first IC tag 73A-1 and the second IC tag 73A-2 on the game field F.

Thus, in the second embodiment, the tag ID of the first IC tag 73A-1 stored in the first IC tag 73A-1 and the tag ID of the second IC tag 73A-2 stored in the second IC tag 73A-2 The positions of the first IC tag 73A-1 and the second IC tag 73A-2 on the game field F are identified based on the positions of the first IC tag 73A-1 and the second IC tag 73A-2 on the game field F Since the vertical and horizontal orientations of the card 60SA are identified based on the relationship, the tag ID of the first IC tag 73A-1 and the tag ID of the second IC tag 73A-2 are "the basis for identifying the state of the object 100A." It is equivalent to “information that becomes available”.

[3. Third Embodiment] A third embodiment of the present invention will be described.

The third embodiment differs from the first embodiment in that the card orientation (front and back orientation) is specified based on information stored in the IC tag. Differences from the first embodiment will be described below. In addition, below, the same code|symbol is used regarding the element same as the element of 1st Embodiment, and the description is abbreviate|omitted.

[3-1. Outline] FIG. 29 shows an example of the sleeve 70B of the third embodiment. FIG. 29 shows a cross-sectional view of sleeve 70B when sleeve 70B is viewed from the side. As with the sleeve 70 of the first embodiment, the surface portion 71B of the sleeve 70B is transparent so that the surface 61 of the card 60 accommodated within the sleeve 70B can be viewed from outside the sleeve 70B. Also, like the sleeve 70 of the first embodiment, the back surface portion 72B of the sleeve 70B is opaque and has an appearance common to all sleeves 70B.

As shown in FIG. 29, the sleeve 70B includes a first IC tag 73B-1, a second IC tag 73B-2, and a blocking surface portion 74B. For example, the blocking surface portion 74B has the same (or substantially the same) shape and size as the back surface portion 72B of the sleeve 70B. The upper and lower ends of the blocking surface portion 74B are connected to the upper and lower ends of the back surface portion 72B, and the blocking surface portion 74B is fixed to the sleeve 70B.

The first surface 75B of the blocking surface portion 74B faces the surface portion 71B of the sleeve 70B. A first IC tag 73B-1 is provided on the first surface 75B. Therefore, the first IC tag 73B-1 faces the surface portion 71B of the sleeve 70B. The second surface 76B of the blocking surface portion 74B faces the rear surface portion 72B of the sleeve 70B. A second IC tag 73B-2 is provided on the second surface 76B. Therefore, the second IC tag 73B-2 faces the rear surface portion 72B of the sleeve 70B.

The tag ID of the first IC tag 73B-1 is stored in the first IC tag 73B-1, and the tag ID of the second IC tag 73B-2 is stored in the second IC tag 73B-2. Since the first IC tag 73B-1 and the second IC tag 73B-2 are separate IC tags, their tag IDs are different from each other.

The blocking surface portion 74B is made of a material (for example, a magnetic material) that prevents signal transmission/reception between the first IC tag 73B-1 and the second IC tag 73B-2 and the reader 20. FIG. Therefore, a signal transmitted from the second surface 76B (back surface portion 72B) side is received by the first IC tag 73B-1, and a signal from the first IC tag 73B-1 is received by the second surface 76B (back surface portion 72B) side. ) side is blocked by the blocking surface portion 74B. Similarly, the signal transmitted from the first surface 75B (surface portion 71B) side is received by the second IC tag 73B-2, and the signal from the second IC tag 73B-2 is received by the first surface 75B (surface portion 71B) side. ) side is blocked by the blocking surface portion 74B.

The card 60 is accommodated in the space between the surface portion 71B and the blocking surface portion 74B of the sleeve 70B. Hereinafter, the card 60 housed in the sleeve 70B will be referred to as "card 60SB" for the sake of convenience in order to distinguish it from the card 60 alone. In other words, the card 60 and the sleeve 70B when the card 60 is housed in the sleeve 70B are regarded as one object and described as "card 60SB".

When the card 60SB is placed face up in zone Z, the card 60SB is placed so that the back surface portion 72B of the card 60SB and the game field F are in contact with each other. In this case, since the signal transmission/reception between the reader 20 installed under the zone Z and the first IC tag 73B-1 is blocked by the blocking surface portion 74B (such as a magnetic material), the data stored in the first IC tag 73B-1 The received information (tag ID, etc.) is not read by the reader 20 . As a result, information is read by the reader 20 only from the second IC tag 73B-2.

On the other hand, when the card 60SB is placed face down in the zone Z, the card 60SB is placed so that the surface portion 71B of the card 60SB and the game field F are in contact with each other. In this case, since the signal transmission/reception between the reader 20 installed under the zone Z and the second IC tag 73B-2 is blocked by the blocking surface portion 74B (such as a magnetic material), the second IC tag 73B-2 The stored tag ID is not read by the reader 20 . As a result, information (tag ID, etc.) is read by the reader 20 only from the first IC tag 73B-1.

Thus, when the card 60SB is placed face up, the information is read by the reader 20 only from the second IC tag 73B-2. Similarly, when the card 60SB is placed face down, the information is read by the reader 20 only from the first IC tag 73B-1. Therefore, the orientation of the front and back of the card 60SB can be specified based on which of the first IC tag 73B-1 and the second IC tag 73B-2 the information stored is read.

[3-2. Processing] Processing executed by the system 1B according to the third embodiment will be described.

[3-2-1] FIG. 30 shows an example of association processing in the third embodiment. In the third embodiment, the association process shown in FIG. 30 is executed instead of the association process shown in FIG.

For example, the player places one card 60SB from his or her deck vertically and face up in a predetermined zone Z (for example, zone Z11) in the game field F. FIG. In this state, the association processing shown in FIG. 30 is executed.

As shown in FIG. 30, first, the control unit 41 of the information processing device 40 acquires the photographed image of the photographing device 30 (S400B). Then, the control unit 41 identifies the card ID of the card 60SB appearing in the captured image from the captured image (S402B). Steps S400B and S402B are the same as steps S400 and S402 in FIG.

Also, the control unit 41 acquires the tag ID read by the reader 20 (S404B). When the card 60SB is placed face up, the tag ID stored in the second IC tag 73B-2 is read by the reading device 20, and the read tag ID is supplied to the information processing device 40. FIG. The control unit 41 acquires the tag ID supplied in this manner.

After executing step S404B, the control unit 41 outputs a turnover request notification requesting the player to turn over the card 60SB (S406B). For example, the control unit 41 displays on the display unit 45 an image showing the turnover request notification. Alternatively, the control unit 41 causes the audio output unit 46 to output a sound indicating the turnover request notification.

In response to the turnover request notification, the player turns over the card 60SB placed in the zone Z to turn the card 60SB face down. In this state, the processes after step S408B are executed.

That is, the control unit 41 acquires the tag ID read by the reader 20 (S408B). When the card 60SB is placed face down, the tag ID stored in the first IC tag 73B-1 is read by the reading device 20, and the read tag ID is supplied to the information processing device 40. FIG. The control unit 41 acquires the tag ID supplied in this manner.

Then, the control unit 41 registers the association between the card ID specified in step S402B and the tag ID obtained in steps S404B and S408B in the association data D1B (S410B).

FIG. 31 shows an example of association data D1B. As shown in FIG. 31, the association data D1B includes "card ID" and "tag ID" fields. The "card ID" field is the same as the "card ID" field of the association data D1 in the first embodiment. The "Tag ID" field includes "front side" and "back side" fields as subfields. The "face up" field is a field for registering the tag ID obtained when the card 60SB is placed face up (ie, the tag ID of the second IC tag 73B-2). The "face down" field is a field for registering the tag ID obtained when the card 60SB is placed face down (that is, the tag ID of the first IC tag 73B-1).

In step S410B, control unit 41 adds a new record to association data D1B, registers the card ID identified in step S402B in the "card ID" field, and registers the tag ID obtained in step S404B in the "face up" field. , and the tag ID obtained in step S408B is registered in the "face down" field.

After step S410B is executed, a completion notification indicating that the association processing is completed is output, the player removes the card 60SB placed in the zone Z, and places the next card 60SB from his/her deck vertically and face up. Place it in zone Z above. In this state, the association processing shown in FIG. 30 is executed again.

By executing the association process shown in FIG. 30 for each card 60SB included in the first player's deck, information on all cards 60SB included in the first player's deck is registered in the association data D1B. Information of all the cards 60SB included in the second player's deck is registered in the association data D1B by executing the association process shown in FIG. 30 also for each card 60SB included in the second player's deck.

[3-2-2] FIG. 32 shows another example of the association processing of the third embodiment. Instead of the association processing shown in FIG. 30, the association processing shown in FIG. 32 may be executed.

Note that the association process shown in FIG. 32 assumes that an IC tag writer for writing information to the first IC tag 73B-1 and the second IC tag 73B-2 is installed under the zone Z described above. In the following description, it is assumed that the reader 20 is an IC tag reader/writer having both IC tag reader and IC tag writer functions.

As shown in FIG. 32, first, the control unit 41 acquires the photographed image of the photographing device 30 (S420B). Then, the control unit 41 identifies the card ID of the card 60SB appearing in the captured image from the captured image (S422B). The processes of steps S420B and S422B are the same as steps S400 and S402 of FIG.

After executing step S422B, the control unit 41 writes the card ID specified in step S422B and the front/back flag to the second IC tag 73B-2 of the card 60SB placed in the zone Z (S424B).

The front/back flag is information indicating whether the card 60SB is placed face up or face down. For example, the value "0" or "1" is set as the front/back flag. A value of "0" indicates that the card 60SB is placed face up, and a value of "1" indicates that the card 60SB is placed face down. In step S424B, the value "0" indicating the front side is written as the front/back flag.

The control unit 41 sends an instruction to write the card ID specified in step S422B and the front/back flag (0) to the reader 20 (IC tag reader/writer) placed under the zone Z above. Then, in response to the above write instruction, the reading device 20 writes the card ID and front/back flag (0) to the second IC tag 73B-2 of the card 60SB placed in the zone Z above. In this case, since the transmission/reception of signals between the first IC tag 73B-1 and the reader 20 is blocked by the blocking surface portion 74B (such as a magnetic material), writing to the first IC tag 73B-1 is not performed at this time. can't break

After executing step S424B, the control unit 41 outputs a turnover request notification requesting the player to turn over the card 60SB (S426B). The processing of step S426B is the same as that of step S406B in FIG.

In response to the turnover request notification, the player turns over the card 60SB placed in the zone Z to turn the card 60SB face down. In this state, the process of step S428B is executed.

That is, the control unit 41 writes the card ID specified in step S422B and the front/back flag to the first IC tag 73B-1 of the card 60SB placed in the zone Z (S428B). In this case, the value "1" indicating the back side is written as the front/back flag.

Specifically, the control unit 41 instructs the reading device 20 (IC tag reader/writer) placed under the zone Z to write the card ID specified in step S422B and the front/back flag (1). send. Then, in response to the above write instruction, the reading device 20 writes the card ID and front/back flag (1) to the first IC tag 73B-1 of the card 60SB placed in the zone Z above. In this case, since the signal transmission/reception between the second IC tag 73B-2 and the reader 20 is blocked by the blocking surface portion 74B (magnetic material, etc.), writing to the second IC tag 73B-2 is not performed at this time. .

After step S428B is executed, a completion notice indicating that the association processing is completed is output, the first player removes the card 60SB placed in the zone Z, and places the next card 60SB vertically and vertically from his/her own deck. Place it face up in zone Z above. In this state, the association processing shown in FIG. 32 is executed again.

By executing the association process shown in FIG. 32 for each card 60SB included in the first player's deck, the first IC tag 73B-1 and the second IC tag 73B of each card 60SB included in the first player's deck are displayed. -2 stores a card ID and a front/back flag. 32 is executed for each card 60SB included in the deck of the second player, the first IC tag 73B-1 and the second IC tag 73B-1 of each card 60SB included in the The 2IC tag 73B-2 also stores a card ID and a front/back flag.

[3-2-3] Also in the third embodiment, a specific process similar to the specific process shown in FIG. 13 is executed. Here, the identification processing of the third embodiment will be described with reference to FIG. 13 . Further, here, it is assumed that the association data D1B shown in FIG. 31 is stored in the storage unit 42. FIG.

In the third embodiment, in step S432, the control unit 41 specifies the position and vertical/horizontal orientation of the card 60SB placed on the game field F, but does not specify the front/back orientation of the card 60SB. In this case, the identification result in step S432 is registered in the first identification result data D2B.

FIG. 33 shows an example of the first identification result data D2B. As shown in FIG. 33, the first identification result data D2B includes "area ID" and "vertical/horizontal flag" fields. The "area ID" and "vertical/horizontal flag" fields are the same as the "area ID" and "vertical/horizontal flag" fields of the first identification result data D2 of the first embodiment.

Further, in the third embodiment, in step S436, the control unit 41 identifies the card ID, position, and front/back orientation of the card 60SB placed on the game field F. FIG.

For example, when the card 60SB is placed face up in the zone Z10, the tag ID stored in the second IC tag 73B-2 is read by the reader 20-10, and information is obtained as read result data of the reader 20-10. It is supplied to the processing device 40 . In this case, since the transmission/reception of signals between the first IC tag 73B-1 and the reader 20-10 is blocked by the shielding surface portion 74B, the tag ID stored in the first IC tag 73B-1 cannot be read by the reader 20-10. not read by 10.

Based on the tag ID read by the reader 20-10, the control unit 41 identifies the card ID and the orientation of the front and back of the card 60SB. The method of specifying the card ID is basically the same as in step S436 of the first embodiment, except that the association data D1B is referred to instead of the association data D1.

The control unit 41 refers to the association data D1B and determines in which of the "front" and "back" fields the tag ID read by the reader 20-10 is registered. Then, if the tag ID read by the reader 20-10 is registered in the "face up" field, the control unit 41 identifies that the card 60SB is face up. On the other hand, if the tag ID read by the reader 20-10 is registered in the "face down" field, the control unit 41 identifies that the card 60SB is face down.

In this case, the identification result in step S426 is registered in the second identification result data D3B. FIG. 34 shows an example of the second identification result data D3B. As shown in FIG. 34, the second identification result data D3B includes "reader ID", "card ID", and "front/back flag" fields. The "reader ID" and "card ID" fields are the same as the "reader ID" and "card ID" fields of the second identification result data D3 of the first embodiment, and the "front and back flag" fields are the same as those of the first embodiment. This is the same as the "front/back flag" field of the first identification result data D2.

For example, when the tag ID is read by the reader 20-10, the control unit 41 reads the card ID and front/back orientation specified from the tag ID as the “card ID” and the “card ID” of the record with the reader ID “R10”. Register in the "front and back flag" field.

In the above description, it is assumed that the association data D1B shown in FIG. 31 is stored in the storage unit 42 by the association processing shown in FIG. When the flags are stored in the first IC tag 73B-1 and the second IC tag 73B-2 of the card 60SB, the card ID and front/back flag are read by the reader 20-10. registers the card ID and front/back flag read by the reader 20-10 in the "card ID" and "front/back flag" fields of the record with the reader ID "R10".

Further, in the third embodiment, in step S438, the control section 41 generates the game field situation data D4 based on the first identification result data D2B and the second identification result data D3B. The game field situation data D4 is the same as in the first embodiment. In addition, the processing of step S438 in this case is the same as that of step S438, except that the front/back flag registered in the "front/back flag" field of the second identification result data D3B is registered in the "front/back flag" field of the game field status data D4. Similar to step S438 of one embodiment.

In the situation shown in FIG. 7, the card bundle 600-1 (that is, a plurality of cards 60SB stacked face down) is placed in the zone Z7. exists, only the ID tag stored in the first IC tag 73B-1 of the bottom card 60SB in the card bundle 600-1 is read. As a result, in the "card ID" field of the record with the reader ID "R7" in the second identification result data D3B and the record with the zone ID "Z7" in the game field situation data D4, the bundle of cards placed in the zone Z7 is displayed. Only the card ID of the bottom card 60SB in 600-1 is registered. The same applies to zones Z1, Z15 and Z21.

[3-2-4] Also in the third embodiment, the display control process shown in FIG. 18 and the process shown in FIG. 19 are executed. However, in the parts PA-1 to PA-4 of the game field image G of the third embodiment, numerical values indicating the number of cards 60SB included in the card bundles 600-1 to 600-4 are not displayed.

[3-3. Effect] According to the third embodiment, the orientation of the front and back of the card 60SB placed on the game field F can be specified based on the reading result of the reader 20. FIG.

In the third embodiment, when the card 60SB is placed face up, the information stored in the first IC tag 73B-1 is guaranteed not to be read by the reader 20, and the card 60SB is placed face up. It is necessary to ensure that the information stored in the second IC tag 73B-2 cannot be read by the reader 20 when placed in an orientation.

For example, when the card 60SB is placed face up, the distance between the first IC tag 73B-1 and the reader 20 increases (that is, the information stored in the first IC tag 73B-1 is read by the reader 20 large enough to be unreadable), and the distance between the second IC tag 73B-2 and the reader 20 when the card 60SB is placed face down also becomes large (that is, the distance stored in the second IC tag 73B-2) If the read information is too large to be read by the reading device 20), there is no need to take special measures for security. However, since the card 60 and the sleeve 70 are thin and the above distance does not become large, it is necessary to devise measures for the above collateral. In this regard, in the third embodiment, the above security is realized by providing the shielding surface portion 74B inside the sleeve 70B.

[3-4. Modification] A modification of the third embodiment will be described.

[3-4-1] In the embodiment described above, the second IC tag 73B-2 is installed on the second surface 76B of the shielding surface portion 74B, but the second IC tag 73B-2 is installed on the back surface portion 72B of the sleeve 70B. may be placed on the inner surface of the

[3-4-2] In the embodiment described above, the shielding surface portion 74B is fixed to the sleeve 70B, but the shielding surface portion 74B is attached to the sleeve 70B together with the card 60, such as the object 80 shown in FIG. It may be a sheet-like object housed inside.

[3-4-3] In the embodiments described above, the shielding surface portion 74B is made of a magnetic material, but the shielding surface portion 74B may be made of a material other than a magnetic material. It prevents the transmission and reception of signals between the first IC tag 73B-1 and the reader 20 through the back surface portion 72B of the sleeve 70B, and prevents the transmission of signals between the second IC tag 73B-2 and the reader 20. Any material that can prevent transmission and reception via the surface portion 71A of the sleeve 70B can be used as the material for the blocking surface portion 74B.

[3-4-4] Also in the third embodiment, in step S422, the control section 41 may specify the front and back orientation of the card 60SB. That is, the control unit 41 may specify the front and back orientation of the card 60SB from the photographed image of the photographing device 30 and also specify the front and back orientation of the card 60SB from the reading result of the reading device 20 . In this case, the identification result of the front and back orientation obtained from the photographed image of the photographing device 30 and the identification result of the front and back orientation obtained from the reading result of the reading device 20 are collated to obtain the identification result of the front and back orientation. You may make it raise the precision of.

[3-5. Functional Elements] FIG. 35 is a functional block diagram for explaining functional elements included in the system 1B according to the third embodiment. Note that FIG. 35 shows functional elements that are the same as the functional elements of the first embodiment (imaging unit 110, captured image acquiring unit 120, reading unit 130, reading result acquiring unit 140, display control unit 160, and display unit 170). are given the same reference numerals as in FIG. 22, and the description of these functional elements is omitted here, and the target object 100B and the specifying unit 150B will be described. Also, with respect to the description of wording, the description of points that overlap with the first embodiment will be omitted.

[3-5-1] First, the object 100B will be described. Here, differences between the target object 100B and the target object 100 in the first embodiment will be described.

Object 100B includes a first surface and a second surface. These first surface portion and second surface portion are the same as the first surface portion and second surface portion described as being included in the object 100 of the first embodiment.

Moreover, the target object 100B includes a first holding portion 101B and a second holding portion 102B. The first holding unit 101B and the second holding unit 102B hold specific information for specifying the type and state of the target object 100B placed on the target surface. The identification information in this case includes basic information for identifying the type of the target object 100B and basic information for identifying the state of the target object 100B. When the target object 100B is an object in which a game medium is stored in a container, information serving as a basis for specifying the type or state of the game medium placed on the target surface while being stored in the container. corresponds to "basic information for identifying the type or state of the object 100B".

Information held in the first holding unit 101B and the second holding unit 102B is read by the reading unit 130 . First holding unit 101B and second holding unit 102B are arranged so that information read by reading unit 130 can be distinguished between first holding unit 101B and second holding unit 102B. contains different information. For example, the identification information of the first holding unit 101B is held in the first holding unit 101B, and the identification information of the second holding unit 102B is held in the second holding unit 102B. In the third embodiment, the orientation of the front and back of the object 100B is specified based on the different information held in each of the first holding unit 101B and the second holding unit 102B. 100B corresponds to "basic information for specifying the state of 100B".

Further, object 100B includes restriction portion 103B. The restriction unit 103B restricts reading of the information held in the first holding unit 101B by the reading unit 130 through the second surface portion of the target object 100B. to limit reading of information held in the object 100B through the first surface of the object 100B.

For example, the first holding unit 101B is a first IC tag installed to communicate with the reading unit 130 (IC tag reader) via the first surface of the object 100B. In other words, the first holding unit 101B is a first IC tag whose communication with the reading unit 130 (IC tag reader) via the second surface of the object 100B is restricted.

Also, the second holding unit 102B is a second IC tag installed so as to communicate with the reading unit 130 (IC tag reader) via the second surface of the object 100B. In other words, the second holding part 102B is a second IC tag whose communication with the reading part 130 (IC tag reader) via the first surface part of the object 100B is restricted.

The first IC tag is installed so as to face the first surface of the object 100B. Alternatively, the first IC tag is installed on the inner surface of the first surface portion of the object 100B. Also, the first IC tag is installed closer to the first surface portion of the object 100B than the second IC tag. Also, the second IC tag is installed so as to face the second surface of the object 100B. Alternatively, the second IC tag is installed on the inner surface of the second surface portion of the object 100B. Also, the second IC tag is installed closer to the second surface of the object 100B than the first IC tag.

The first IC tag is arranged between the first surface portion of the object 100B and the restriction portion 103B, and the second IC tag is arranged between the second surface portion of the object 100B and the restriction portion 103B. The restriction unit 103B restricts communication between the first IC tag and the reading device 20 for reading the information held in the first IC tag or the second IC tag from being performed via the second surface portion of the target object 100B. , restrict communication between the reader 20 and the second IC tag through the first surface of the object 100B.

For example, the restriction part 103B includes a magnetic material provided between the first IC tag and the second surface part of the object 100B. Also, the restricting portion 103B includes a magnetic material provided between the second IC tag and the first surface portion of the target object 100B. In other words, restriction section 103B includes a magnetic material provided between the first IC tag and the second IC tag. The signal (radio wave) from the first IC tag is blocked from being transmitted via the second surface of the object 100B, or the signal (radio wave) from the second IC tag is transmitted via the first surface of the object 100B. As long as it can block being blocked, it can be used as the restricting unit 103B.

[3-5-2] The identification unit 150B will be described. The identifying portion 150B includes a first identifying portion 151B and a second identifying portion 152B.

The first specifying unit 151B specifies the position and orientation of the target object 100B based on the image captured by the image capturing device 30 . For example, the first identifying unit 151B identifies the position and the vertical and horizontal orientation of the target object 100B in the same manner as the first identifying unit 151 of the first embodiment.

The second specifying unit 152B specifies the position, type, and orientation of the target object 100B based on the reading result of the reading device 20. FIG. The second specifying unit 152B specifies the position and type of the object 100B in the same manner as the second specifying unit 152 of the first embodiment.

The second specifying unit 152B also specifies the orientation of the front and back of the object 100B. That is, the second specifying unit 152B reads the information stored in the first holding unit 101B (first IC tag) or the second holding unit 102B (second IC tag) by the reading device 20, and identifies the object 100B. It is specified which of the first surface portion and the second surface portion the object 100B is placed on the target surface so as to face the target surface.

For example, when the information stored in first holding portion 101B (first IC tag) is read by reading portion 130, second specifying portion 152B determines that the first surface portion of object 100B is facing reading portion 130. determine that it is suitable. For example, if the reading unit 130 is installed below the target surface, the second identifying unit 152B determines that the first surface of the target object 100B faces the target surface. Note that when the reading unit 130 is installed above the target surface, the second specifying unit 152B determines that the second surface of the target object 100B faces the target surface.

On the other hand, when the information stored in second holding unit 102B (second IC tag) is read by reading unit 130, second identifying unit 152B determines that the second surface of object 100B is facing reading unit 130. determine that it is suitable. For example, when the reading unit 130 is installed below the target surface, the second identifying unit 152B determines that the second surface of the target object 100B faces the target surface. Note that when the reading unit 130 is installed above the target surface, the second specifying unit 152B determines that the first surface portion of the target object 100B faces the target surface.

[3-5-3] In the example of the card game described above, the card 60SB corresponds to an example of the object 100B. Further, the surface portion 71B and the back surface portion 72B of the sleeve 70B correspond to examples of the "first surface portion" and the "second surface portion", respectively. Also, the first IC tag 73B-1 and the second IC tag 73A-2 of the sleeve 70B correspond to examples of the first holding portion 101B (first IC tag) and the second holding portion 102B (second IC tag), respectively. Furthermore, the blocking surface portion 74B of the sleeve 70B corresponds to an example of the restricting portion 103B.

For example, when the information stored in the first IC tag 73B-1 of the card 60SB is read by the reader 20, the second identification unit 152B identifies that the card 60SB is placed face down. On the other hand, when the information stored in the second IC tag 73B-2 of the card 60SB is read by the reader 20, the second identification unit 152B identifies that the card 60SB is placed face up.

[4. Fourth Embodiment] A fourth embodiment of the present invention will be described.

The fourth embodiment differs from the first embodiment in that the type or state of the card is specified by reading a code printed on the sleeve with invisible ink. Differences from the first embodiment will be described below. In addition, below, the same code|symbol is used regarding the element same as the element of 1st Embodiment, and the description is abbreviate|omitted.

[4-1. Overview] FIG. 36 shows the configuration of a system 1C according to the fourth embodiment. As shown in FIG. 36, the system 1C includes a game board 10C, a first photographing device 30C-1, a second photographing device 30C-2, an information processing device 40, and a display terminal device 50. FIG. The information processing device 40 and the display terminal device 50 are the same as in the first embodiment.

The game board 10C is basically the same as the game board 10 of the first embodiment, except that the reader 20 (IC tag reader) is not included.

The first imaging device 30C-1 corresponds to the imaging device 30 of the first embodiment, and is a visible light camera. On the other hand, the second imaging device 30C-2 is an invisible light camera (for example, an infrared camera, etc.). A second imaging device 30C-2 is used to read codes printed with invisible ink. “Invisible ink” is ink (eg, infrared ink) that can be recognized by an image sensor by irradiating it with invisible light (eg, infrared rays, etc.).

FIG. 37 is a diagram for explaining an example of the sleeve 70C of the fourth embodiment. As with the sleeve 70 of the first embodiment, the surface portion 71C of the sleeve 70C is transparent so that the surface 61 of the card 60 housed in the sleeve 70C can be viewed from outside the sleeve 70C. Further, like the sleeves 70 of the first embodiment, the rear surface portions 72C of the sleeves 70C are opaque, and the external appearance of the rear surface portions 72C visible to the human eye is the same for all the sleeves 70C.

Surface portion 71C of sleeve 70C includes first cord 77C-1. The first code 77C-1 is printed with invisible ink on the outer surface of the surface portion 71C. Although the first code 77C-1 is printed in the center of the surface portion 71C in FIG. 37, the first code 77C-1 may be printed in a position other than the center. The first code 77C-1 is a code embedded with the sleeve ID of the sleeve 70C. That is, the first code 77C-1 is obtained by coding the sleeve ID of the sleeve 70C according to a predetermined standard (rule). In other words, the first code 77C-1 is a code including a pattern generated based on the sleeve ID of the sleeve 70C (a pattern unique to the sleeve ID). The first code 77C-1 is, for example, a two-dimensional code (QR code (registered trademark), etc.). The sleeve ID is information for uniquely identifying each sleeve 70C.

Also, the back surface portion 72C of the sleeve 70C includes a second cord 77C-2. The second code 77C-2 is printed with invisible ink on the outer surface of the back surface portion 72C. Like the first code 77C-1, the second code 77C-2 is also a code embedded with the sleeve ID of the sleeve 70C. That is, the sleeve ID of sleeve 70C is embedded in both first code 77C-1 and second code 77C-2.

In the following, the first code 77C-1 and the second code 77C-2 may be collectively referred to as "code 77C". Further, hereinafter, the card 60 housed in the sleeve 70C will be referred to as "card 60SC" for the sake of convenience in order to distinguish it from the card 60 alone. In other words, the card 60 and the sleeve 70C when the card 60 is accommodated in the sleeve 70C are regarded as one object and described as "card 60SC".

Similar to the first photographing device 30C-1, the second photographing device 30C-2 is also fixed above the game field F. At least the zones Z1 to Z30 of the game field F are also included in the image captured by the second image capturing device 30C-2.

For example, the second imaging device 30C-2 captures the reflected light reflected by the light source that irradiates the game field F with invisible light and the game field F or the card 60SC placed on the game field F to create an electronic image. and an image sensor that converts and outputs a signal. Reflected light from which visible light (disturbance light) has been removed is input to the image sensor. The second photographing device 30C-2 is used to read the first code 77C-1 or the second code 77C-2 of the card 60SC placed on the game field F.

The second photographing device 30C-2 and the information processing device 40 are connected via a cable complying with a predetermined interface standard. Alternatively, the second photographing device 30C-2 and the information processing device 40 can communicate via a communication network. The second photographing device 30C-2 photographs the game field F at predetermined time intervals, and the photographed images are supplied to the information processing device 40 via the cable or communication network.

When the game field F is placed with the card 60SC facing up, the image captured by the second image capturing device 30C-2 includes the first code 77C-1 of the surface portion 71C of the card 60SC. Then, the information (sleeve ID) embedded in the first code 77C-1 is acquired. On the other hand, when the card 60SC is placed face down on the game field F, the image captured by the second photographing device 30C-2 includes the second code 77C-2 on the back surface 72C of the card 60SC. Information (sleeve ID) embedded in the second code 77C-2 is obtained based on the image.

[4-2. Processing] Processing executed by the system 1C according to the fourth embodiment will be described.

[4-2-1] FIG. 38 shows an example of association processing in the fourth embodiment. For example, the player places one card 60SC from his or her deck vertically and face up in a predetermined zone Z (for example, zone Z11) in the game field F. FIG. In this state, the association processing shown in FIG. 38 is executed.

As shown in FIG. 38, first, the control unit 41 of the information processing device 40 acquires an image captured by the first image capturing device 30C-1 (S400C). Then, the control unit 41 identifies the card ID of the card 60SC appearing in the photographed image from the photographed image (S402C). Steps S400C and S402C are the same as steps S400 and S402 in FIG.

Also, the control unit 41 acquires the image captured by the second image capturing device 30C-2 (S404C). Then, the control unit 41 acquires the sleeve ID from the first code 72C-1 appearing in the captured image (S406C). Then, control unit 41 registers the association between the card ID specified in step S402C and the sleeve ID obtained in step S406C in association data D1C (S408C).

FIG. 39 shows an example of association data D1C in the fourth embodiment. As shown in FIG. 39, the association data D1C includes "card ID" and "sleeve ID" fields. The "card ID" field is the same as the "card ID" field of the association data D1 of the first embodiment. A "sleeve ID" field is a field for registering a sleeve ID.

In step S408C, the control unit 41 adds a new record to the association data D1C, and stores the card ID specified in step S402C and the card ID obtained in step S406C in the "card ID" and "sleeve ID" fields of the record. Register the given sleeve ID.

After step S408C is executed, a completion notification indicating that the association processing is completed is output, and the player removes the card 60SC placed in the zone Z and inserts the next card 60SC from his or her deck vertically and face up. Place it in zone Z above. In this state, the association processing shown in FIG. 38 is executed again.

By executing the association process shown in FIG. 38 for each card 60SC included in the first player's deck, information on all cards 60SC included in the first player's deck is registered in the association data D1C. Also, with respect to each card 60SC included in the deck of the second player, the association processing shown in FIG. 38 is executed, whereby information of all the cards 60SC included in the deck of the second player is registered in the association data D1C. .

[4-2-2] FIG. 40 shows an example of identification processing in the fourth embodiment. As shown in FIG. 40, first, the control unit 41 of the information processing device 40 acquires an image captured by the first image capturing device 30C-1 (S430C). Then, the control unit 41 identifies the position and orientation of the card 60SC from the captured image (S432C). The processes of steps S430C and S432C are the same as steps S430 and S432 of FIG. The identification result in step S432C is registered in the first identification result data D2. The first identification result data D2 is the same as in the first embodiment.

After executing step S432C, the control unit 41 acquires the captured image of the second image capturing device 30C-2 (S434C), and the control unit 41 identifies the position and card ID of the card 60SC from the captured image (S436C).

For example, the control unit 41 determines whether or not the code 77C (the first code 77C-1 or the second code 77C-2) appears in each of the areas A1 to A30 of the captured image. Also, the control unit 41 acquires the sleeve ID from the code 77C that is shown.

The identification result in step S436C is registered in the second identification result data D3C. FIG. 41 shows an example of the second identification result data D3C. As shown in FIG. 41, the second identification result data D3C includes "region ID" and "card ID" fields. The "area ID" field is the same as the "area ID" field of the first identification result data D2 of the first embodiment, and the "card ID" field is the "card ID" of the second identification result data D3 of the first embodiment. Similar to fields.

For example, if the code 77C appears in the area A10, the control unit 41 registers the sleeve ID acquired from the code 77C in the "card ID" field of the record with the area ID "A10".

After executing step S436C, the control section 41 generates the game field situation data D4 based on the first identification result data D2 and the second identification result data D3C (S438C). The game field situation data D4 is the same as in the first embodiment.

In the situation shown in FIG. 7, the card bundle 600-1 (that is, a plurality of cards 60SC stacked face down) is placed in zone Z7, but in the fourth embodiment, it is placed in zone Z7. Only the second code 77C-2 of the uppermost card 60SC of the bundle of cards 600-1 thus picked up appears in the photographed image of the second photographing device 30C-2. Therefore, the card bundle 600 placed in the zone Z7 is displayed in the "card ID" field of the record with the area ID "A7" in the second identification result data D3C and the record with the zone ID "Z7" in the game field situation data D4. -1 only the card ID of the top card 60SC is registered. The same applies to zones Z1, Z15 and Z21.

[4-2-3] Also in the fourth embodiment, the display control process shown in FIG. 18 and the process shown in FIG. 19 are executed. However, in the parts PA-1 to PA-4 of the game field image G of the fourth embodiment, numerical values indicating the number of cards 60SC included in the card bundles 600-1 to 600-4 are not displayed.

[4-3. Effect] According to the fourth embodiment, when the card 60SC is placed face up on the game field F, the first code 77C-1 on the surface portion 71C of the card 60SC is photographed by the second photographing device 30C-2. By doing so, the information embedded in the first code 77C-1 can be read, and as a result, the card ID of the card 60SC can be acquired. On the other hand, when the card 60SC is placed face down on the game field F, the second code 77C-2 on the back surface 72C of the card 60SC is photographed by the second photographing device 30C-2. The information embedded in 77C-2 can be read and, as a result, the card ID of card 60SC can be obtained. Thus, according to the fourth embodiment, the card ID of the card 60SC can be acquired regardless of whether the card 60SC is placed face up or face down.

According to the fourth embodiment, even when the card 60SC is placed face down on the game field F (that is, when the card 60SC is placed on the game field F with the front side 61 invisible), Based on the information held in the second code 77C-2 of the back surface portion 72C of the card 60SC, the information written on the front surface 61 of the card 60 (such as the name and performance of the card 60) can be identified.

Further, according to the fourth embodiment, since the code 77C is printed on the sleeve 70C, even if the code 77C is not printed on the card 60 itself, the card 60 can be accommodated in the sleeve 70C and used. , the type and state of the card 60 can be specified based on the image captured by the second image capturing device 30C-2. That is, since the code 77C does not have to be printed on the card 60 itself, it is possible to use an existing card 60 on which the code 77C is not printed, for example.

Further, according to the fourth embodiment, since the code 77C is printed in an invisible state, the appearance of the card 60SC (card 60) seen from a person is not damaged. In addition, when the card 60SC is placed face down on the game field F, the opponent can rely on the second code 77C-2 printed on the back side 72C to determine the name and performance of the card 60 which should not be known originally. It is also possible to try not to be able to grasp etc.

[4-4. Modification] A modification of the fourth embodiment will be described.

[4-4-1] For example, in the first code 77C-1, along with the sleeve ID, information indicating that the code is printed on the surface portion 71C may be embedded. Further, in the second code 77C-2, along with the sleeve ID, information indicating that the code is printed on the back surface portion 72C may be embedded.

Specifically, the first code 77C-1 is embedded with the sleeve ID as a front/back flag and "0" indicating the front side, and the second code 77C-2 is embedded with the sleeve ID as a front/back flag. , "1" may be embedded to indicate the back side. Then, the sleeve ID and front/back flag may be obtained from the code 77C appearing in the photographed image of the second photographing device 30C-2.

In this way, when the card 60SC is placed face up, "0" is acquired as the front/back flag from the first code 77C-1, thereby specifying that the card 60SC is placed face up. When the card 60SC is placed face down, it can be specified that the card 60SC is placed face down by obtaining "1" as the front/back flag from the second code 77C-2. That is, the orientation of the front and back of the card 60SC can be specified based on the image captured by the second image capturing device 30C-2. In other words, the state of the card 60SC can be specified based on the image captured by the second image capturing device 30C-2.

[4-4-2] For example, like the first IC tag 73-1 and the second IC tag 73C-2 of the second embodiment, even if a plurality of codes 77C having a predetermined positional relationship are printed on the back surface portion 72C, good. When the card 60SC is placed face down, the vertical and horizontal orientation of the card 60SC is specified based on the positional relationship of the plurality of codes 77C captured in the image captured by the second photographing device 30C-2. may

A plurality of codes 77C having a predetermined positional relationship may also be printed on the surface portion 71C. When the card 60SC is placed face up, the vertical and horizontal orientation of the card 60SC is specified based on the positional relationship of the plurality of codes 77C captured in the image captured by the second photographing device 30C-2. good too.

In this way, the vertical and horizontal orientation of the card 60SC can be specified based on the captured image of the second imaging device 30C-2.

[4-4-3] Further, for example, the card ID of the card 60 may be embedded with the first code 77C-1 and the second code 77C-2.

[4-5. Functional Elements] FIG. 42 is a functional block diagram for explaining functional elements included in the system 1C according to the fourth embodiment. In FIG. 42, the same functional elements (display control unit 160 and display unit 170) as those in the first embodiment are given the same reference numerals as in FIG. omitted. Also, with respect to the description of wording, the description of points that overlap with the first embodiment will be omitted.

[4-5-1] First, the object 100C will be described. The target object 100C is an object in which a game medium is stored in a storage body.

A game medium has a surface (hereinafter referred to as a “characteristic surface” for convenience) having an appearance corresponding to the type of the game medium. For example, a characteristic face is a face that has an appearance unique to the type of play medium. Further, for example, the characteristic surface is a surface on which text or a pattern corresponding to the type of game medium is printed.

The container includes a first side and a second side. These first surface portion and second surface portion are the same as the first surface portion and second surface portion described as being included in the container (target object 100) in the first embodiment. When the game medium is stored in the storage body, the first surface portion (inner surface of the first surface portion) and the characteristic surface of the game object face each other. For example, all or part of the first surface portion is formed using a transparent material (transparent film, etc.), and the first surface portion allows the characteristic surface of the play object housed in the container to be viewed from outside the container to the first surface. It is configured to be visible through the surface portion.

The object 100C includes a first holding portion 101C and a second holding portion 102C. The first holding portion 101C is provided on the first surface portion of the container. 101 C of 1st holding|maintenance parts are for holding|maintaining the 1st specific information for specifying the kind or state of the play media accommodated in the container.

For example, the first specific information is written on the first surface of the target object 100C (container) in an invisible state that is not visually recognized by humans. In this case, the portion where the first identification information is written in an invisible state corresponds to the first holding portion 101C. For example, the first identifying information is inscribed on the first surface using invisible ink. In addition, for example, the first identification information is written on the outer surface of the first surface portion.

The "first identification information" is information serving as a basis for identifying at least one of the type and state of the game media contained in the container. In other words, the "first specification information" serves as the basis for specifying the type of game media contained in the container and the basis for specifying the state of the game media contained in the container. and/or information.

For example, there is data that associates a container ID that uniquely identifies a container with a game medium ID of a game medium contained in the container, and based on the container ID, the game played in the container is identified. When the type of medium can be identified, the "first identification information" includes the container ID as "basic information for identifying the type of game medium contained in the container". Also, for example, the "first specific information" may include a game medium ID that uniquely identifies the type of game medium.

Further, for example, the "first identification information" may include first identification information for identifying the first holding unit 101C as "basic information for identifying the state of the game media contained in the container". For example, when the first identification information stored in the first holding portion 101C of the first surface portion is read, the target object 100C is placed on the target surface so that the second surface portion and the target surface are in contact with each other. It is specified that For this reason, the "first identification information" is the first identification information that identifies the first holding portion 101C, and the "arrangement format of the target object 100C (the second surface portion and the target surface are in contact with each other so that the target object 100C is the target). It may be included as "basic information for specifying whether it is placed on the surface".

On the other hand, the second holding portion 102C is provided on the second surface portion of the container. The second holding section 102C is for holding second identification information for identifying the type or state of the game media contained in the container.

For example, the second specific information is written on the second surface of the object 100C (container) in an invisible state that is not visually recognized by humans. In this case, the portion where the second identification information is written in an invisible state corresponds to the second holding portion 102C. For example, the second identification information is written on the second surface using invisible ink. In addition, for example, the second identification information is written on the outer surface of the second surface portion.

As with the first specification information, the "second specification information" is information serving as a basis for specifying at least one of the type and state of the game media contained in the container.

For example, the "second identification information" may be the container ID of the container or the game medium ID of the game media contained in the container as a basis for specifying the type of the game medium contained in the container. “Information”.

Further, for example, the "second identification information" may include second identification information for identifying the second holding unit 102C as "basic information for identifying the state of the target object 100C". For example, when the second identification information stored in the second holding portion 102C of the second surface portion is read, the target object 100C is placed on the target surface so that the first surface portion and the target surface are in contact with each other. It is specified that For this reason, the "second identification information" is the second identification information that identifies the second holding portion 102C as the "arrangement format of the target object 100C (the first surface portion and the target surface are in contact with each other, and the target object 100C is the target. It may be included as "basic information for specifying whether it is placed on the surface".

In addition, when each of the first specific information and the second specific information includes only "information serving as a basis for specifying the type of game media contained in the container", the first specific information and the second specific information are the same information.

When the object 100C is placed on the target surface such that the outer surface of the first surface and the target surface are in contact with each other, the first surface and the second surface of the container are arranged so that the second holding portion 102C of the second surface is held. can be read by the reading unit 130C, and the target object 100C is placed on the target surface so that the outer surface of the second surface portion and the target surface are in contact with each other. The positional relationship is such that the reading unit 130C can read the first specific information held by the first holding portion 101C of the first surface portion.

For example, when the target object 100C is placed on the target surface such that the outer surface of the first surface and the target surface are in contact with each other, the first surface and the second surface of the container may be the outer surface of the second surface. faces upward, it becomes possible to read the second specific information held in the second holding portion 102C of the second surface portion through the device installed above the target surface, and the outside of the second surface portion When the target object 100C is placed on the target surface so that the side surface and the target surface are in contact with each other, the outer surface of the first surface portion faces upward, and the device installed above the target surface The positional relationship is such that the first specific information held in the first holding portion 101C of the first surface portion can be read.

In the case of the card game example described above, the card 60SC corresponds to an example of the object 100C, the card 60 corresponds to an example of the "game medium", and the sleeve 70C corresponds to an example of the "container". Further, the surface portion 71C and the back surface portion 72C of the sleeve 70C correspond to examples of the "first surface portion" and the "second surface portion".

Furthermore, the first cord 77C-1 and the second cord 77C-2 correspond to examples of the first holding portion 101C and the second holding portion 102C. Also, the sleeve ID corresponds to an example of the "first specific information" and the "second specific information". Further, in the case of the modified example in which the front/back flag is embedded in each of the first code 77C-1 and the second code 77C-2, the front/back flag also corresponds to an example of "first specific information" and "second specific information". .

[4-5-2] The first photographing unit 110C is realized by the first photographing device 30C-1. The first photographing unit 110C photographs the target surface on which the target object 100C is placed. For example, the first imaging unit 110C images the target plane from above the target plane. The first imaging unit 110C may be capable of imaging the entire target plane, or may be capable of imaging only a region of the target plane where the target object 100C may be placed. 120 C of 1st picked-up image acquisition parts acquire the picked-up image of 110 C of 1st imaging|photography parts.

[4-5-3] The second photographing unit 180C is realized by the second photographing device 30C-2. The second photographing unit 180C photographs the target surface on which the target object 100C is placed. The second imaging unit 180C captures the reflected light (invisible light) reflected by the light source that irradiates the target surface with invisible light and the target surface or the target object 100C placed on the target surface, and converts it into an electronic image signal. and an image sensor that converts and outputs. For example, the second photographing unit 180C photographs the target plane from above the target plane. The second photographing unit 180C may be capable of photographing the entire target plane, or may be capable of photographing only a region of the target plane where the target object 100C may be placed. The second photographed image acquisition section 190C acquires the photographed image of the second photographing section 180C.

[4-5-4] The reading unit 130C reads the first specific information held in the first holding unit 101C. The reading unit 130C reads the first specific information based on the captured image of the second imaging unit 180C. Also, the reading unit 130C reads the second specific information held in the second holding unit 102C. The reading unit 130C reads the second specific information based on the image captured by the second imaging unit 180C.

When the object 100C is placed on the object surface so that the first surface portion of the object 100C (container) and the object surface are in contact with each other, the object 100C is held by the second holding portion 102C of the second surface portion of the object 100C. The second specific information can be read by the reading unit 130C. On the other hand, when the object 100C is placed on the target surface so that the second surface of the object 100C (container) and the object surface are in contact with each other, the first holding portion 101C of the first surface of the object 100C is The retained first specific information becomes readable by the reading unit 130C.

In the example of the card game described above, when the card 60SC is placed face up, the first code 77C-1 appears in the photographed image of the second photographing device 30C-2. read the sleeve ID (or front/back flag) embedded in the On the other hand, when the card 60SC is placed face down, the second code 77C-2 appears in the captured image of the second photographing device 30C-2. Read the ID (or front/back flag).

[4-5-5] The identifying unit 150C identifies the position and state of the object 100C based on the image captured by the first imaging unit 110C and the reading result of the reading unit 130C. The identifying portion 150C includes a first identifying portion 151C and a second identifying portion 152C.

For example, the first identifying unit 151C identifies the position and orientation of the target object 100C based on the image captured by the first imaging unit 110C. Also, the second specifying unit 152C specifies the position and type of the object 100C based on the reading result of the reading unit 130C. The second specifying unit 152C may specify the position, type, and orientation of the object 100C based on the reading result of the reading unit 130C.

In the case of the card game example described above, the first identifying unit 151C identifies the position, vertical/horizontal orientation, and front/back orientation of the card 60SC based on the image captured by the first imaging unit 110C. The second specifying unit 152C also specifies the position and card ID of the card 60SC based on the reading result of the reading unit 130C.

[4-5-6] The second surface portion of the object 100C (container) may include a third holding portion provided so as to have a predetermined positional relationship with the second holding portion 102C.

That is, as in the modification described above, a plurality of codes 77C may be printed on the back surface portion 72C as well as the first IC tag 73A-1 and the second IC tag 73A-2 of the second embodiment. That is, the back surface portion 72C may include, apart from the second cord 77C-2, a third cord (an example of a third holding portion) having a predetermined positional relationship with the second cord 77C-2.

In this case, as with the first IC tag 73A-1 and the second IC tag 73A-2 of the second embodiment, the second code 77C-2 and the third code are different in position on the outer surface of the back surface portion 72C. placed as follows. The second code 77C-2 and the third code are arranged so that the orientation of the card 60SC can be identified from the positional relationship between the second code 77C-2 and the third code when the card 60SC is placed face up on the game field. placed in position.

In this way, when the card 60SC is placed face down, the vertical and horizontal orientation of the card 60SC can be identified based on the positional relationship between the second code 77C-2 and the third code. The same applies to the surface portion 71C.

[5. Modifications] The present invention is not limited to the first to fourth embodiments described above.

[5-1] For example, the second embodiment and the third embodiment may be combined. That is, one sleeve may be provided with an IC tag for identifying the vertical and horizontal orientation in addition to the IC tag for identifying the front and back orientation. For example, one sleeve may be provided with three or four or more IC tags. In this case, the photographing device 30 is not necessarily required to specify the position and state of the card 60 (position, vertical/horizontal orientation, front/back orientation).

For example, like the sleeve 70A shown in FIG. A blocking surface portion corresponding to only the lower half of the blocking surface portion 74B shown in FIG. 29 is also provided in the sleeve. A third IC tag corresponding to the first IC tag 73B-1 shown in FIG.

In this case, since there is a shielding surface portion between the second IC tag and the third IC tag existing in the lower half of the sleeve, the card 60 accommodated in the sleeve is placed face up on the game field F. , the signal from the second IC tag is received by the reader 20, the signal from the third IC tag is not received by the reader 20, and the card 60 accommodated in the sleeve is turned face down. , the signal from the third IC tag is received by the reader 20 and the signal from the second IC tag is not received by the reader 20 . As a result, depending on whether the signal from the second IC tag or the third IC tag is received by the reader 20, it can be specified whether the card 60 accommodated in the sleeve is placed face up or face down.

Also, in this case, since the first IC tag present in the upper half of the sleeve is not affected by the blocking surface, the card 60 stored in the sleeve can be placed face up or face down in the game field F. The signal from the first IC tag is received by the reader 20 even when placed on the . As a result, when the card 60 accommodated in the sleeve is placed face up, the signals from the first IC tag and the second IC tag are received by the reader 20, and the respective positions of the first IC tag and the second IC tag are detected. can be identified, the vertical and horizontal orientation of the card 60 can be identified from the positional relationship between the first IC tag and the second IC tag. On the other hand, when the card 60 accommodated in the sleeve is placed face down, the signals from the first IC tag and the third IC tag are received by the reader 20, and the respective positions of the first IC tag and the third IC tag are detected. can be identified, the vertical and horizontal orientation of the card 60 can be identified from the positional relationship between the first IC tag and the third IC tag.

Thus, according to the sleeve provided with three IC tags (first to third IC tags) as described above, the card 60 placed on the game field F can be oriented upside down based on the reading result of the reader 20. In addition, the vertical and horizontal orientation of the card 60 can be identified based on the reading result of the reader 20 regardless of whether the card 60 is placed face up or face down.

23 on each of the first surface 75B of the shielding surface portion 74B in the sleeve 70B shown in FIG. Four IC tags may be provided in one sleeve by providing two IC tags corresponding to the first IC tag 73A-1 and the second IC tag 73A-2 shown in FIG. In this way, the orientation of the card 60 placed on the game field F can be specified based on the reading result of the reader 20, and the card 60 can be placed face up or face down. However, the vertical and horizontal orientation of the card 60 can be specified based on the reading result of the reading device 20 .

[5-2] Further, for example, any one of the first to third embodiments may be combined with the fourth embodiment. That is, both the IC tag and the invisible code may be provided on the sleeve (or card 60).

[5-3] Although the card game has been mainly described above, the present invention can also be applied to games other than the card game. The present invention can be applied to games played using objects placed on an object surface.

According to the invention described in D3), the second surface portion is further provided with the third holding portion provided so as to have a predetermined positional relationship with the second holding portion, so that the first surface portion and the target surface are separated from each other. When a game medium stored in the storage body is placed on the target surface so as to touch, the orientation of the game medium can be specified based on the positional relationship between the second holding section and the third holding section.

D4) A container (for example, 70C) according to another aspect of the present invention is an individual player used in a game played using a game medium (for example, 60) placed on a target surface (for example, game field F). A container for containing a play medium, wherein the play medium includes a surface (for example, 61) having an appearance corresponding to the type of the play medium, and the container is configured such that the play medium A first surface portion that faces the surface when stored, so that the surface of the game medium stored in the storage body can be visually recognized from outside the storage body through the first surface portion. A configured first surface portion (for example, 71C), a second surface portion (for example, 72C) different from the first surface portion, and a type of the play medium provided in the second surface portion and stored in the storage body or and a holding part (for example, 77C-2) for holding specific information for specifying a state, and the game housed in the housing body such that the first surface part and the target surface are in contact with each other. When the medium is placed on the object surface, the specific information held in the holding portion of the second surface portion can be read by reading means (130).

According to the invention described in D4), when the game medium contained in the container is placed on the target surface so that the first surface portion of the container and the target surface are in contact with each other (that is, depending on the type of play medium, Even when a game medium contained in a container is placed on a target surface in a state in which the surface having an appropriate appearance cannot be seen), the specific information held by the holding portion of the second surface portion is read by the reading means. Based on the specific information that is read, it is possible to identify the type of play medium placed on the target surface while being contained in the container.

Further, according to the invention described in D4), when the specific information held in the holding portion of the second surface portion is read by the reading means, the first surface portion and the target surface are in contact with each other, and the containing body Since it can be identified that the game medium contained in the container is placed on the target surface, is the game medium contained in the container placed on the target surface so that the first surface portion and the target surface are in contact with each other? can identify whether or not In other words, it is possible to specify the state of the game medium placed on the target surface while being accommodated in the accommodation body.

In this way, according to the invention described in D4), it is possible to specify the type or state of the game medium placed on the target surface in the real world while allowing existing game objects to be used in the game. or easier to identify).
