The web server WS may be connected to a DB server (DB), and may provide the game data stored in the DB server to the player.

Hereinafter, the rules of a typical dart game and the stats of the players associated therewith will be described.

A dart game that can be performed by the dart game apparatus 100 according to an embodiment of the present invention includes a 01 game (zero circle game), a cricket game, a count-up game, .

01 game progresses by alternating between two teams (or two players), throwing darts to a dart target one round at a time. One round includes three dart draws. The objective of the game is to have the sum of the points of each round reach the target score (score of 100 or 1000 units, which generally ends at 01, such as 301, 501, 701, 901, 1101, 1501, etc.). The target score and play round may be arbitrarily adjustable depending on the number of participating players.

The cricket game, like the 01 game, will perform a round by throwing three darts in the first round. In the case of a STANDARD cricket game, it can be done using only the fire area in the center of the dart target and the 20, 19, 18, 17, 16 and 15 point areas. If you mark the cricket number 3, it will be marked with your position. If you hit more than 4 marks, the score corresponding to the number will be added to compete the score. Here, the double area and the triple area of the dart target can be calculated as 2 marks and 3 marks, respectively. If the opponent of the player also marks the cricket number 3 while the cricket number is marked with his or her position, the cricket number is considered to be closed, and the score may not be added any more. The object of the game may be to obtain a high score until the end of the stipulation round, or to close all of the cricket numbers and achieve a higher score than the opponent.

A count-up game is a game that will win if you earn high points within a given round.

In addition to the above-mentioned games, various types of games can be played by the dart game device 100, and the play mode of the dart game device 100 is not limited by the game method described above. For example, by measuring the speed of a dart pin and utilizing it, additional game methods in various ways can be created. For example, a game method may be created in which a point is added to a user who draws a dart pin with a speed value that most matches a predetermined speed value. Alternatively, in addition to the general game method described above, the average speed of the dart pins of the prominent dart game players is calculated and stored, and then the average speed of the dart pins of the general player is compared with the speed of a specific one of the prominent players By outputting the data, the entertainment aspect of the dart game can be further strengthened.

In one aspect of the present invention, the player's stat can be defined according to the game rule independently of the count-up game, the cricket game, and the win or loss of the 01 game.

For example, Points Per Dart (PPD) can be calculated in a 01 game by dividing the total score the player scored by the number of dart draws. Alternatively, the Marks Per Round (MPR) may be calculated by calculating the number of marks marked by the player per round. For example, in a cricket game, MPR is (3 + 1 + 2) when a player makes three dart draws in one round and hits 15 triples, 19 singles, and 20 doubles respectively in three dart draws. / 1 = 6.00 (MPR). In the following round, if the player makes three dart draws and each misses a mark, 18 doubles, and 20 singles, MPR will be (3 + 1 + 2 + 0 + 2+ 1) / 2 = 4.5 (MPR) .

These PPDs and MPRs can be stored as personal data or identification data of a player as stats of a player or a player. Alternatively, the average score of the player per game in the count-up game, the record of the player's highest score per game, and the like can also be stored as the player's stat.

The dart game device 100 can play the dart game and transfer the game record per player to the game server GS or the DB server DB in accordance with the mode. The game server GS or the DB server DB may calculate the player-specific PPD and / or MPR according to the game record and store it as a cumulative PPD and / or MPR stat of the player. In addition, the game server GS or the DB server DB can individually store the game record of the player. For example, in a 01 game, a count-up game, or a cricket game in which the player has played before, the player can record information about the segment portion of the dart hit on each dart draw. The game server GS or the DB server DB may store such player's cumulative (average) PPD and / or MPR data, top PPD and / or MPR data.

The game server GS or the DB server DB may be two physically separated servers. Alternatively, the game server GS and the DB server DB are one physically integrated server, and may be classified according to roles performed in the server. Also, as described above, one server can perform both roles of a game server GS and a DB server DB.

The game server GS or the DB server DB can store the player's individual stats and can give the player a rating (or class (class)) according to the stats. The rating and / or class (class) that may be awarded to the player in accordance with the PPD and / or MPR may be stored as personal data or personally identifiable information.

FIG. 4A illustrates, by way of example, the shape of a dart pin 400 according to an embodiment of the present invention.

The dart pin 400 in FIG. 4A may include both a dart pin of a soft dart and a dart pin of a hard dart.

4A, a dart pin 400 according to an aspect of the present invention includes a tip 401, a barrel 402, a shaft 403, a flight (not shown) 404 and a user identification module 405.

In addition, the shape of the dart pin 400 shown in Fig. 4 is merely an example, and dart pins of various shapes may be present. For example, although FIG. 4A depicts a plurality of grooves and / or protrusions on the outer surface of the barrel 402, the shape of the barrel 402 without such grooves and / or protrusions is also within the scope of this specification .

The tip 401 forms one end of the dart pin 400 and one end may contact the dart target of the dart game device. That is, the tip 401 can hit the dart target (or the dart board) directly. In the case of a hard dart (or a steel dart), the tip 401 may be made of a metal material, and in the case of a soft dart, the tip 401 may be made of a plastic material. This tip 401 may be referred to as a short tip or a long tip, depending on the size of the tip 401 in the case of a soft dart.

In one aspect of the present invention, the barrel 402 may be coupled at one end to the other end of the tip 401 to form the body of the dart pin 400. Generally, the barrel 402 may be made of metal and may have various weights, materials, center of gravity, cutting style, and the like. For example, the metal that can constitute the barrel 402 may include various metals such as brass, tungsten, nickel, and combinations thereof.

In one aspect of the present invention, the weight of the dart pin 400 may depend on the shape and material of the barrel 402. For example, the weight of the dart pin 400 may be 16 g to 20 g (for soft darts), or 20 g to 50 g (for hard darts). The weight of such a dart pin 400 is exemplary only, and various weights may be possible according to user preferences, dart game rules.

In addition, the barrel 402 may have various center of gravity, and the locus of the dart pin 400 when the barrel 402 is projected may be different depending on the position of the center of gravity of the barrel 402.

The shaft 403 can be engaged with the other end of the barrel 402 at one end. The shaft 403 can connect the barrel 402 and the flight 404. The shaft 403 may have various lengths or materials and may be an element that determines the center of gravity of the dart pin 400.

The flight 404 forms the other end of the dart pin 400 and one end can engage the other end of the shaft 403. Such a flight 404 may be related to the flight of the dart pin 400 and the flight trajectory of the projected dart pin 400 may vary depending on the shape of the flight 404. Flight 404 may be constructed from a variety of materials such as plastic, cloth, and the like.

The components 401, 402, 403, 404, and 405 of the above-described dart pin 400 may be combined in various forms. For example, the barrel 402 and the shaft 403 may each include a female thread or male threaded groove or protrusion, so that the two components can be coupled as they rotate clockwise or counterclockwise. Additionally, the components 401, 402, 403, 404, and 405 of such a dart pin 400 may be connected to each other by various bonding and attaching methods such as injection molding, ultrasonic welding, and the like.

The dart pin 400 according to one aspect of the present invention may include a user identification module 405. The user identification module 405 may include short range communication modules such as Bluetooth, NFC, RFID, IC chip, and microchip.

The user identification module 405 in accordance with an aspect of the present invention may be coupled to at least one of the tip 401, the barrel 402, the shaft 403 and the flight 404 of the dart pin 400. For example, the user identification module 405 may be attached to the outer surface of the shaft 403 or inserted therein. When the user identification module 405 is inserted into the shaft 403, the shaft 403 may include an opening for forming a space for inserting the user identification module 403 therein.

In another example, the user identification module 405 may be configured in an annular or circular configuration so that it may be attached in the form of wrapping the outer circumferential surface of the shaft 403. When the user identification module 405 is attached to the outer surface of the shaft 403, the user identification module 405 may function as a handle portion of the dart pin 400 that can provide the user with a good grip on the dart . Alternatively, the user identification module 405 may indicate the handle portion of the dart pin 400. The user identification module may be attached to the side of one of the barrel 402 or the shaft 403 to indicate the handle portion of the dart pin 400. [

In addition, the user identification module 405 may include a removable shape on the dart pin 400.

In another example, the user identification module 405 may be attached to a portion (e.g., a back portion) of the flight 404 such that the user can adjust the flight path or center of gravity of the dart pin 400 .

Accordingly, when the tip 401 of the dart pin 400 contacts the dart target of the dart game device, the user information, identification information, or the like of the dart pin 400 to the dart game device via the user identification module 405 A unique number or the like may be transmitted.

In another example, the user identification module 405 may have the shape of a pipe covering the outer periphery of the shaft 403 of the dart pin 400.

Although the user identification module 405 is illustrated as being coupled to the shaft 403 of the dart pin 400 in the foregoing example, this user identification module 405 may be used in a similar manner to the tips 401, Or may be coupled to barrel 402 and / or flight 404.

For example, when the user identification module 405 is attached to the outer circumferential surface of the barrel 402 made of a metal material, in order to prevent interference of the electromagnetic wave due to the metal material, a separate nonconductive material And a user identification module 405 may be attached to the outer circumferential surface of such a member.

Alternatively, the user identification module 405 may be coupled in the form of surrounding the outer circumferential surface of a portion of the component of the dart pin 400, and the outer circumferential surface of the combined user identification module 405 may be further coupled So that the user identification module 405 may be protected from an external impact.

4B illustrates an exemplary shape of a dart pin according to another embodiment of the present invention.

4B, the user identification module 405 may be coupled to one component (e.g., the shaft 403) of the dart pin 400, for example, coupled to a portion of the annularly shaped splice.

The user identification module 405 may be coupled to the dart pins 400 without any separate couplings or the user identification module 405 may be coupled to the dart pins 400 ). ≪ / RTI > That is, there may also be various coupling schemes between the dart pin 400 and the user identification module 405.

4C illustrates an exemplary shape of a dart pin according to another embodiment of the present invention.

The example shown in FIG. 4C illustratively illustrates that the user identification module 405 can be inserted into a portion of the dart pin 400. The user identification module 405 can be inserted into the components 401, 402, 403, and 404 of the dart pin 400 in a variety of ways.

4C, when the user identification module 405 is inserted into the shaft 403, the shaft 403 has an opening for forming a space for inserting the user identification module 403 therein .

Although only a portion of the user identification module 405 is shown as being inserted into the dart pins 400 in Figure 4c, the entire user identification module 405 is inserted into the dart pins 400, 405 may not be visible. In addition, the user identification module 405 shown in FIG. 4C may be removably inserted into the shaft 403 of the dart pin 400.

In one aspect of the present invention, the user identification module 405 may be inserted into the space at the junction of the barrel 402 and the shaft 403 of the dart pin 400. When the barrel 402 and the shaft 403 are combined and the radius or diameter of one of the components of the barrel 402 and the shaft 403 is made wider, the user identification module 405 may use this radius or diameter May be formed to have a thickness equal to the difference. Accordingly, as the user identification module 405 is inserted, the coupling between the barrel 402 and the shaft 403 can be secured.

Although the barrel 402 and the shaft 403 have been described in the above example, the component (s) into which the user identification module 405 is inserted is not limited thereto.

Additionally, the user identification module 405 may be coupled to a plurality of components of the components of the dart pin 400. For example, in the presence of a first user identification module coupled to the barrel 402 and a second user identification module coupled to the shaft 403, there may be a combination of components, such as a user's barrel- Recording, speed information, user information, reward effect, and the like may be stored.

FIG. 5 illustrates operations performed between components within a dart game system 500 according to an embodiment of the present invention.

The dart game system 500 according to an aspect of the present invention may include a dart (pin) 501, a dart game device 502, and a dart game server 503.

When the user projects a dart pin 501 in playing the dart game or when the dart pin 501 reaches the dart target, the identification information of the dart pin through the user identification module combined with the dart pin 501 User information may be communicated to the dart game device 502 (504). As described above, the user authentication unit of the dart game apparatus 502 can be configured to perform close-range communication with the user identification module.

For example, if the user identification module 405 of the dart pin 501 is implemented with the NFC technology, the user identification module of the dart pin 501 may be a passive NFC (i.e., a tag) The user authentication unit of the mobile station 502 may include an active NFC (i.e., a reader role). In addition, both the user identification module 405 and the user authentication unit may operate in an active communication mode. In this case, the user authentication module of the dart game device 502 and the user identification module 405 of the dart pin 501 may communicate with each other using the generated RF (Radio Frequency) field to allow P2P communication.

The NFC module may be operated at a frequency of, for example, 13.56 MHz, and a mode in which the NFC module can be operated may include a card mode (or a card emulation mode), a Read / Write mode, a P2P mode, . Here, the card emulation mode can be implemented in such a manner that, for example, the information stored in the user identification module 405 as a passive tag is transmitted to the active reader (e.g., the user authentication section) by the user identification module 405. [ As another example, the Read / Write mode may be implemented by the user identification module 405 reading the passive tag information of the user authentication unit. As another example, the P2P mode refers to a manner in which both the user authentication unit of the dart game device 502 and the user identification module 405 of the dart pin 501 can actively communicate with each other, as described above.

In a further aspect of the invention, when the user identification module 405 and the user authentication portion are implemented via RFID technology, these components may operate as RFID tags and / or RFID readers. The RFID tag and the RFID reader may be composed of an antenna and / or a chip. For example, the user identification module 405 may include an RFID tag, and the user authentication unit may include an RFID reader.

These RFID tags can be classified into passive type, semi-passive type, and active type depending on the power used. Passive type means reading data only by the power of the reader, semi-passive type uses self-power for reading data because self-power such as battery is embedded in the tag, and power of the reader is used for communication , And the active type may mean the case where the power of the tag is used to both read and communicate data. In addition, the RFID tag and the RFID reader use a low-frequency IDentification (LFID) (120 to 140KHz), a high-frequency IDentification (HFID) (13.56Mhz), an ultra high- frequency IDentification (UHFID) (868 to 956Mhz) And the like.

5, the dart game device 502 can recognize (505) the identification information of the dart pins and / or the user information of the dart pins via the user authentication unit. Further, the dart game device 502 compares information recognized or stored through the dart pins with information in its own memory (for example, by comparing unique numbers in the information, etc.), and extracts user information or identification information matching the dart pins Or search.

In addition, the dart game device 502 (e.g., a network connection) may forward 506 information from the dart pin to the dart game server 503. In this case, the dart game server 503 may authenticate the user or the dart pin by searching the identification information of the matching user or dart pin with the received information (507).

The dart game server 503 may then pass information to the dart game device 502 about the authenticated user or dart pin. In this case, the information transmitted from the dart game server 503 to the dart game device 502 may include at least one of the authentication information of the user, the identification information of the user, the personal record of the user, the record by the competition / time / place / game type, Such as a pin-by-pin game record, a reward effect, a record of a component or combination of components of a dart pin, a speed of a dart pin, and the like.

Here, the reward effect may include rewards having various forms in units of dart pins. For example, a reward may be generated by outputting pre-stored images, sounds and / or images on a per user basis (UX enhancement), providing additional scores for a particular user or dart pin Providing a separate effect when performing a particular mission with a pin (providing a mission), allowing only authorized dart pins to be used for a particular tournament (as a tournament entry cost), and so on.

The dart game device 502 may then generate or output a reward effect based on the information received from the server 503. [ Additionally, the operations of such a server 503 may be implemented by the dart game device 502 (e.g., control and / or memory).

The technical features shown in FIG. 5 are exemplary only, and similar operations may be implemented by additional components (e.g., other dart game devices or other types of servers) within the dart game system 500.

When the dart pin 601 is projected by the user, the user identification module included in the dart pin 601 and the user authentication unit 602 of the dart game device 100 can exchange data through short-distance communication .

For example, when the user holds the dart pin 601 and is ready to project it, or when the dart pin 601 is projected or the dart pin 601 is projected to reach the dart target, The identification information can be transmitted to the dart game device 100. [ In this case, the dart game device 100 may perform the login procedure for performing the dart game based on the transmitted identification information. That is, the login procedure can be implemented through short-distance communication between the dart pin 601 and the user authentication unit 602 of the dart game apparatus 100 without a separate login procedure.

In other words, a unique number may be assigned to each dart pin 601. Such a unique number may be transmitted to the dart game device and the server, the server may search for a user number matching the unique number, Lt; / RTI > can be implemented. Alternatively, the user information may be input to the dart pin 601, and the input user information may be transmitted to the dart game device to recognize the user at the dart game device.

Therefore, through a short distance communication between the user identification module coupled to the dart pin 601 and the user authentication unit 602 of the dart game apparatus, a user who has a better user experience As shown in FIG.
