       FIG. 1  is a block diagram of a dart game apparatus according to an exemplary embodiment of the present disclosure. 
     The dart game apparatus  100  may include a dart target  110 , a sensing unit  120 , a user input unit  130 , an output unit  140 , a camera unit  150 , a network connection unit  160 , a user recognition unit  170 , a memory  180 , a controller  190 , and the like. The components illustrated in  FIG. 1  are not required. Therefore, the dart game apparatus  100  having more components therethan or less components therethan may be implemented. 
     Hereinafter, the components will be described in sequence. 
     The dart target  110  may include a score board in which a bullseye is positioned at the center and there are areas segmented by a concentric circle centering the bullseye and straight lines extended radially from the bullseye and granted with individual scores, respectively. Multiple holes into which a tip of a dart may be inserted may be formed on the score board. 
     The dart target  110  includes a display unit  142  to be described below to variably change score deployments of the dart target  110  and shapes of areas granted with the scores. In this case, the dart target  110  includes a light transmissive touch pad in the display module  142  to be stacked to take a form of a touch screen. 
     The sensing unit  120  may sense a play of a dart game player performed with respect to the dart target  110 . The sensing unit  120  may sense a hit location of a dart pin so as to actually evaluate the play of the game player. The sensing unit  120  may sense which area of the dart target  110  the thrown dart hits, with respect to a play in which the game player throws the dart. The sensing unit  120  electrically converts a score corresponding to the area in which the dart sticks to transmit the converted score to the controller  190 . 
     A location identification unit  121  may identify positional information of the dart pin which sticks in the dart target  110  by interlocking with the sensing unit  120 . 
     According to the exemplary embodiment of the present disclosure, the location identification unit  121  may judge the hitting location of the dart pin based on a location identification module included in the dart pin. Furthermore, the location identification unit  121  may judge the hitting location of the dart pin based on a receiving groove of the dart target corresponding to the dart pin which sticks. For example, the location identification unit  121  may identify the hitting location of the dart pin based on a location coordinate granted to each receiving groove of the dart target  110 . That is, respective receiving grooves of the dart target  110  may exist while being granted with positional information such as (1,3), (2, 17), (45, 93), (16, 30), etc. Accordingly, when it is sensed that the dart pin hits each receiving groove, the location of the dart pin may be identified by the positional information. The aforementioned contents are only an example according to the exemplary embodiment of the present disclosure and various methods may be used for identifying the location of the dart pin. 
     Optionally or alternatively, the location identification unit  121  may be included in the controller  190 . 
     In the exemplary embodiment of the present disclosure, the sensing unit  120  may allow the controller  190  to calculate the hitting area at least partially based on information regarding a location where the dart pin identified by the location identification unit  121  directly hits the dart target  110  and a predetermined logic stored in the memory  180 . The hitting area may be calculated as an area of a figure formed by connecting the hitting locations of the dart pins. Alternatively, the hitting area may be calculated based on a segment of the dart target corresponding to the dart pin which sticks in the dart target. 
     The user input unit  130  receives an input of the user for controlling the dart game apparatus  100 . The user input unit  130  may include a keypad, a dome switch, a touch pad (resistive/capacitive), a jog wheel, a jog switch, and the like. The user input unit  130  may also include cameras  151  to  153 , a microphone, or the like. 
     The user input unit  130  may also include a short range communication module (not illustrated). The user input unit  130  may be configured to include the short range communication module (not illustrated) of the network connection unit  160 . When the user input unit  130  includes the short range communication module of the network connection unit  160 , the user input unit  130  may be configured to receive a user input which is input by an external console device. As short range communication technology, Bluetooth, radio frequency identification (RFID), infrared data association (IrDA), ultra wideband (UWB), ZigBee, or the like may be used. 
     For example, when the user input unit  130  performs the short range communication using infrared communication, the external console device may be an infrared remote controller. Alternatively, when the user input unit  130  performs the short range communication using a Bluetooth function, the external console device may be a mobile device including a Bluetooth module. The mobile device including the Bluetooth module may be, for example, a smart phone including the Bluetooth module. 
     The user may select a dart game mode, the number of dart game players, a dart game play mode, a match making request, a match approval, and the like through the user input unit  130 . 
     For example, the user may select the number of dart game players, the dart game play mode (a zero one game, a cricket game, and the like), and the dart game mode (a single play, a network play, and the like) through the user input unit  130 . Further, according to an exemplary embodiment of the present disclosure, the user may select a virtual dart game player through the user input unit  130 . 
     The user input unit  130  receives a signal by sensing a key operation or a touch input of the user or receives speech or a motion through the cameras  151  to  153  or the microphone of the user to convert the received signal, speech, or motion into an input signal. To this end, a known speech recognition technology or a motion recognition technology may be used. 
     The output unit  140  which is used for generating an output related with sight, hearing, or touch may include a sound output unit  141 , a display unit  142 , an illumination unit  143 , and the like. 
     The sound output unit  141  may output audio data received from the network connection unit  160  or stored in the memory  180  in a game sound effect, a game motion guide, a game method description, and the like. The sound output unit  141  may also output a sound signal related with a function (e.g., a game effect sound) performed by the dart game apparatus  100 . The sound output unit  141  may also output a speech of a game player or a third person using another dart game apparatus  100  (see  FIG. 2 ), which is received through the network connection unit  160 . The sound output unit  141  may include a receiver, a speaker, a buzzer, and the like. 
     The display unit  142  displays (outputs) information processed in the dart game apparatus  100  (see  FIG. 2 ). For example, when the dart game apparatus  100  (see  FIG. 2 ) is in a game play mode guidance mode, the display unit  142  may output a selectable game play mode. When the dart game apparatus  100  (see  FIG. 2 ) plays a game, the display unit  142  may display the score sensed through the sensing unit  120  or output an image acquired by photographing the game player or the third person using another dart game apparatus  100  (see  FIG. 2 ) received through the network connection unit  160 . 
     The display unit  142  may output information on various dart games according to the hitting area based on the location of the dart pin according to the exemplary embodiment of the present disclosure. For example, the display unit  142  may output information on a throwing point of the dart pin so as to allow the dart game player to throw the dart pin to a specific area or a specific location. 
     The display unit  142  may graphically generate the hitting area formed by connecting the dart pins which stick in the dart target  110  and provide the graphically generated hitting area. For example, an image showing that a triangular area is formed by connecting three dart pins may be output. Furthermore, the display unit  142  may display contents regarding information (e.g., score calculation information, etc.) on the calculated hitting area. 
     In the case where three dart pin throwing opportunities per one throwing opportunity is given to the dart game player, which location the dart game player may acquire an advantageous score at the time of hitting may be provided as an animation effect based on locations in which two previously thrown dart pins stick. For example, an effect of flickering a specific location by enlarging a specific segment may be provided through the display unit  142 . 
     The display unit  142  may include at least one of a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display, and a 3D display. 
     Some of the displays may be configured as a transparent or light transmissive type to view the outside through the displays. This may be called a transparent display and a representative example of the transparent display includes a transparent OLED (TOLED), and the like. 
     According to an implementation form of the dart game apparatus  100 , two or more displays  142  may exist. For example, in the dart game apparatus  100 , the plurality of displays may be separated from each other or integrally disposed on one surface, and further, disposed on different surfaces, respectively. For example, the display unit  142  may include both a display  142  disposed at an upper end of the dart target  110  and a display disposed at a lower end of the dart target  110 , or may include one display  142  thereof. However, the location where the aforementioned display is disposed is an example, and the display may be disposed at various locations for a demand due to a design or a visual effect. 
     The touch sensor may be configured to convert a change in pressure applied to a specific portion of the display unit  142  or capacitance generated at the specific portion of the display unit  142  into an electrical input signal. The touch sensor may be configured to detect touch pressure as well as a touched position and area. 
     When there is a touch input for the touch sensor, a signal(s) corresponding to the touch input is(are) sent to a touch controller. The touch controller processes the signal(s) and thereafter, transmits data corresponding thereto to the controller  190 . As a result, the controller  190  may know which area of the display  142  is touched. 
     The illumination unit  143  outputs a signal for notifying occurrence of an event of the dart game apparatus  100 . Examples of the event which occurs from the dart game apparatus  100  include identification of the dart game player, direct hit of the dart, a change of the dart game player, game over, and the like. The illumination unit  143  may include a light emission diode (LED) and notify the occurrence of the event to the user by flickering the LED. 
     The LEDs are disposed on the bottom of the dart target  110  to be flickered according to a flickering pattern which is pre-stored according to the occurrence of the event. For example, one or more LEDs may be allocated to respective parts of the dart target  110 . The allocated LEDs are disposed on the bottom of the dart target  110  and may be disposed in a direction orienting the outside of the dart game apparatus  100 . When the LEDs irradiate light, the light irradiated by the LEDs may pass through the dart target  110  made of a transparent or translucent material to transfer a visual output to the user. Alternatively, the light irradiated by the LEDs may transfer the visual output to the user through a gap existing in the dart target  110 . 
     The output unit  140  may also output another form other than a video signal or an audio signal, for example, a signal for notifying the occurrence of the event by vibration. The output unit  140  may include the sound output unit  141 , the display unit  142 , and the illumination unit  143 . 
     The camera unit  150  includes multiple cameras  151  to  153  and an infrared camera (not illustrated), and as a result, an image frame processed by the cameras  151  to  153  may be stored in the memory  180  or transmitted to the outside through the network connection unit  160 . Two or more cameras  150  may be provided according to a use environment. 
     In the aspect of the present disclosure, the camera unit  150  may be disposed to photograph the dart pins which stick in the dart target  110 . For example, the camera unit  150  may be positioned on the bottom of the dart target. Alternatively, the camera unit  150  may be positioned at one area to photograph a direction of the dart target  110  in a housing H (see  FIG. 2 ) on which the dart game apparatus is mounted. In an aspect of the present disclosure, the camera unit  150  may include multiple cameras  151  to  153 . 
     The location identification unit  121  and the controller  190  may calculate the hitting area corresponding to the location of the dart pin by analyzing the location of the dart pin photographed through the camera unit  150 . To this end, an image capturing technology may be used. That is, the location of the dart pin may be identified based on an image acquired by capturing the image photographed through the camera unit  150  photographing the dart target  110 . The hitting area may be calculated through the identified throwing locations of the dart pins. To this end, various image processing technologies may be used. 
     At least some cameras of the camera unit  150  may be disposed to photograph an image frame including the dart target  110  and other cameras may be disposed to photograph an image frame directly related with a game rule in the dart game play. For example, the camera may be disposed to photograph a throw-line on which the dart is thrown in order to photograph the image frame directly related with the dart game rule. The multiple cameras included in the camera unit  150  may be disposed to photograph at least some image frames to overlap with each other. 
     When the camera unit  150  includes one camera, the camera may be a panoramic camera disposed to photograph both at least a part of the dart target  110  and the image frame (e.g., the throw-line in the dart game) directly related with the game rule. 
     The network connection unit  160  may include one or more modules that enable wireless communication between the dart game apparatus  100  and a wired/wireless communication system or between the dart game apparatus  100  and a network on which the dart game apparatus  100  is positioned. 
     The network connection unit  160  may include one or more modules which enable communication with the dart game apparatus  100  and/or the dart pin (not illustrated). 
     The network connection unit  160  may include a wired/wireless Internet module for accessing the network. As the wireless Internet technology, wireless LAN (WLAN) (Wi-Fi), wireless broadband (Wibro), world interoperability for microwave access (Wimax), high speed downlink packet access (HSDPA), or the like, may be used. As wired Internet technology, digital subscriber line (XDSL), fibers to the home (FTTH), power line communication (PLC), or the like may be used. 
     The network connection unit  160  includes a short-range communication module to transmit and receive data to and from an electronic apparatus positioned in a comparatively short range from the dart game apparatus  100  and including the short-range communication module. As short range communication technology, Bluetooth, radio frequency identification (RFID), infrared data association (IrDA), ultra wideband (UWB), ZigBee, or the like may be used. 
     The network connection unit  160  may sense a connection state of the network and a transceiving speed of the network. 
     Data received through the network connection unit  160  may be output through the output unit  140 , stored through the memory  180 , or transmitted to other electronic apparatuses positioned in a short range through the short-range communication module. 
     The network connection unit  160  may receive information for calculating the score by using the location of the dart pin from the dart game apparatus  100 . Alternatively, the network connection unit  160  may receive the positional information from the dart pin. Further, the network connection unit  160  may include at least one of the number of throwing times of the dart pin, which remain in the throwing opportunity of the dart game player to the dart game apparatus  100 , a progress situation of the dart game, a scoring situation of the dart game player, a measured speed of the dart pin, a throwing order of the dart game player, information on the dart game player, and information on a counterpart player of the dart game player. The aforementioned information is just an example and the dart game server  300  (see  FIG. 3 ) may transmit/receive all types of information associated with the dart game apparatus  100  and the dart game. 
     The network connection unit  160  may receive user identification information from the dart game apparatus  100 . 
     The user recognition unit  170  recognizes unique information of a long-range user by using a radio wave through the radio frequency identification (RFID) technology which is a kind of the short range communication technology. For example, the user may possess a card, a mobile terminal, or unique dart game equipment, for example, his/her own personal dart equipment, which includes an RFID module. Information (e.g., a personal ID, an identification code, and the like of the user registered in the server (DB) (see  FIG. 3 )) for identifying the user may be recorded in the RFID module possessed by the user. The dart game apparatus  100  may identify the RFID module possessed by the user to identify a dart game player which plays the game by using the dart game apparatus  100  and update a database for the identified dart game player or accumulate new data. 
     The user recognition unit  170  may include various technologies (e.g., the short-range communication technology such as the Bluetooth, and the like) that may transmit and receive unique information of the user by a contact/non-contact method in addition to the RFID technology. Further, the user recognition unit  170  may include a biodata identification module that identifies biodata (speech, a fingerprint, and a face) of the user by interworking with the microphone of the user input unit  130 , the touch pad, the camera unit  150 , and the like. 
     The memory  180  may store a program for a motion of the controller  190  therein and temporarily store input/output data (e.g., a phone book, a message, a still image, a moving picture, or the like) therein. The memory  180  may store data regarding various patterns of vibrations and sounds output in the touch input on the touch screen. 
     The memory  180  may store various data for calculating the score according to the hitting area based on the location of the dart pin. For example, various logics for calculating the hitting area may be stored in the memory  180 . For example, algorithms for calculating the area of the figure may be stored in the memory  180  in order to acquire the area of the figure formed by connecting the locations of the dart pins. 
     In an additional aspect of the present disclosure, a predetermined logic may be stored in the memory  180  in order to calculate the score according to the location and the hitting area of the dart pin. 
     In the predetermined logic it is may be characterized in that as the hitting area formed by the dart pin increases, an additional point may be granted. According to another exemplary embodiment of the present disclosure, in the predetermined logic, it is may be characterized in that as the hitting area formed by the dart pin decreases, the additional point may be granted. 
     Alternatively, in the predetermined logic, it is may be characterized in that the hitting area formed by the dart pin thrown by a first player may be determined as a score area in which the score is granted only to the first player within a predetermined period. Furthermore, in the predetermined logic, it is may be characterized in that the hitting area formed by the dart pin thrown by the first player may be determined as a score area in which a weighted value is granted to the first player within a predetermined period. 
     In the predetermined logic according to the additional aspect of the present disclosure, it is may be characterized in that when the dart pin thrown from a second player sticks in the hitting area formed by the dart pin thrown by the first player, a penalty is granted to the second player. Further, in the predetermined logic, it is may be characterized in that as the hitting area is formed by the dart pin thrown to a predetermined location of the dart target, the weighted value may be granted. 
     The memory  180  may include at least one type of storage medium of a flash memory type storage medium, a hard disk type storage medium, a multimedia card micro type storage medium, a card type memory (for example, an SD or XD memory, or the like), a random access memory (RAM), a static random access memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, and an optical disk. The dart game apparatus  100  may operate in connection with a web storage performing a storing function of the memory  180  on the Internet. 
     The controller  190  generally controls all motions of the dart game apparatus  100 . For example, in the case of the dart game, a direct hitting location of the dart pin may be sensed at least partially based on a signal received from the sensing unit  120  and the score corresponding to the sensed direct hitting location may be aggregated for each game participant. The controller  190  may perform the dart game based on the score aggregated for each game participant. 
     The controller  190  may perform pattern recognition processing to recognize a motion input, a write input, and the like performed on the touch screen or camera as a text or an image. Further, the controller may perform speech recognition by using a speech-to-text (STT) function to recognize the speech input through the microphone as the text. 
     The controller  190  may include a hitting area calculation unit  191  and a score calculation unit  193 . 
     The hitting area calculation unit  191  may calculate the hitting area of the dart pin based on the hitting location of the dart pin, which is judged by the location identification unit  121 . For example, the area of the figure formed by connecting the hitting locations of the dart pins which stick in the dart target  110  may be calculated. To this end, algorithms for calculating the area of the figure may be used. 
     Alternatively, the hitting area may be calculated based on the segment of the dart target  110  corresponding to the dart pin which sticks. Additionally, the hitting area of the dart pin may be calculated according to a predetermined logic. 
     Alternatively, referring to the above description, in more detail, the dart game apparatus  100  may map location coordinate values (x,y) in respective receiving grooves of the segments of the dart target  110 . When the dart pin reaches a specific receiving groove of the dart target, the sensing unit  120  may sense which receiving groove the dart pin reaches. Furthermore, the sensing unit  120  may transfer information on the sensed receiving groove to the location identification unit  121 . The location identification unit  121  may judge the mapped coordinate value corresponding to the sensed receiving groove. When throwing three or more dart pins is completed, the hitting area calculation unit  191  may calculate the hitting area formed by the dart pin based on the coordinate values judged to correspond to the location which the dart pin reaches. 
     A camera is installed at a location to photograph the dart target  110  in association with the dart game apparatus, and as a result, the camera unit  150  may photograph and/or capture the location which the dart pin reaches. When throwing three or more dart pins is completed, the camera unit  150  may capture locations which the dart pins reach and transfer a captured image to the area calculation unit  191 . The area calculation unit  191  may calculate the hitting area by the dart pin through image processing of the captured image. 
     The score calculation unit  193  may include the score calculation unit  193  that calculates the score based on the hitting area calculated by the hitting area calculation unit  191  and the predetermined logic. As a result, the controller  190  may provide the dart game score according to the hitting area based on the location of the dart pin to the dart game player. 
     When the controller  190  senses that a capacity of the memory is exceeded, the controller  390  may allow data to be deleted in the oldest data order among the data stored in the memory  180 . For example, the controller  190  may allow an image to be deleted in the oldest image order among photographed data photographed and stored by the camera unit  150 . 
     The controller  190  may control the memory  180  to delete unloaded data after a predetermined time period. For example, the controller  190  may control the memory  180  to delete photographed data which is not loaded within 6 months after a specific time period. 
     As illustrated in  FIG. 1 , since the controller  190  may communicate with all of the above-mentioned other components, the controller  190  may organically control operations of the respective components. 
     Various embodiments described herein may be implemented in a computer-readable recording medium or a recording medium readable by a device similar to the computer by using, for example, software, hardware, or a combination thereof.

Each of the software modules may perform one or more functions and operations described in the specification. A software code may be implemented by a software application written by an appropriate program language. The software code may be stored in the memory  180  and executed by the controller  190 . 
       FIG. 2  is a perspective view of a dart game apparatus according to an exemplary embodiment of the present disclosure. 
     As illustrated in  FIG. 2 , the dart game apparatus  100  according to the exemplary embodiment of the present disclosure may be formed by mounting the components illustrated in  FIG. 1  in a housing H. A dart target  110 , a display unit  142 , an illumination unit  143 , a sound output unit  141 , a camera unit  150 , and a user recognition unit  170  may be disposed on the front surface of the dart game apparatus  100 . 
     The dart target  110  may be disposed so that a dead center is positioned at a position (for example, 5 feet 8 inches in a vertical direction from the ground) which conforms with a rule of the dart game. The illumination units  143 - 1 ,  143 - 2 , and  143 - 3  may be disposed at various parts of the dart game apparatus  100  to transfer a visual effect to the player of the dart game apparatus  100 . 
     For example, the illumination unit  143 - 1  is disposed at the side of the dart target  110  and may serve to irradiate an illumination to the dart target  110 . The illumination unit  143 - 1  may also output a predetermined illumination effect according to an event of the dart game. Further, the illumination unit  143 - 1  may output illumination effects having various colors. 
     The illumination unit  143 - 2  may be formed to be extended in a vertical direction along a forward projection of the housing H. Like the illumination unit  143 - 1 , the illumination unit  143 - 2  may output a predetermined illumination effect according to an event of the dart game and output illumination effects having various colors. 
     The illumination unit  143 - 3  may be disposed on the side of the user recognition unit  170 . The illumination unit  143 - 3  may output a predetermined illumination effect according to an event of the dart game and output illumination effects having various colors.

     Optionally, the dart game apparatus  100  may include a dart plate P which may be selectively connected with the dart game apparatus  100  and is extended in a horizontal direction. The dart plate P may further include an illumination unit  143 - 4 . The dart plate P may be integrally coupled with or selectively attached to or detached from the dart game apparatus  100 . 
     When the dart plate P is integrally coupled with or selectively attached to the dart game apparatus  100 , the dart plate P may be electrically connected with the dart game apparatus  100 . The illumination unit  143 - 4  of the dart game apparatus  100  may be disposed along the outside of the dart plate P as illustrated in  FIG. 3 . One end of the dart plate P may be extended to a place where a throw-line is to be positioned according to a distance of the throw-line from the dart target according to a rule of the game. The illumination unit  143 - 4  may be disposed at a position corresponding to the throw-line. 
     Although not illustrated in  FIG. 2 , an illumination unit (not illustrated) is disposed at the bottom of the dart target  110  to irradiate an illumination effect in a user direction. The illumination unit (not illustrated) may include a combination of different illumination elements allocated according to each segment configuring the dart target. 
     For example, the illumination unit (not illustrated) is disposed at the bottom of the dart target  110  to irradiate an illumination effect in a user direction through a predetermined segment. For example, the illumination unit may output the illumination effect so as to allow the dart game player to throw the dart pin to a specific area. Therefore, the dart game player may set a throwing point of the dart pin. For example, the illumination effect may be output to a segment corresponding to an area of triple  3 . Alternatively, the illumination effect may be output to segments corresponding to areas of double  5  and double  17 . 
     The housing H of the dart game apparatus  100  may include the display unit  142  disposed in the user direction. The display unit  142  may display information required for the user according to the progress of the dart game (for example, a collected score, information on a player which is playing the game, a score required for clearing the corresponding game, information of an opponent player which does not play the game, and the like). The display  142  may display a visual effect according to an event depending on the progress of the dart game. For example, when the user continuously hits a bullseye at the dead center of the dart target  100  with three dart throw opportunities, the display unit  142  may display a pre-stored motion picture corresponding to the corresponding event. The motion picture may be stored in the memory  180  of the dart game apparatus  100  or received from a server through the network connection unit  160 . 
     The display unit  142  may provide the user with visual and audible effects according to occurrence of the event by interlocking with the illumination units  143 - 1 ,  143 - 2 ,  143 - 3 , and  143 - 4  and the sound output unit  141 . In other words, when a predetermined event occurs, the display unit  142 , the illumination units  143 - 1 ,  143 - 2 ,  143 - 3 , and  143 - 4 , and the sound output unit  141  may output an illumination effect, a display effect, and a sound effect with respect to the corresponding event together.

     The sound output unit  141  is also disposed on the front surface of the housing H of the dart game apparatus  100  to output a sound. The number and disposed positions of sound output units  141  may also be variously modified. 
     The camera unit  150  may be mounted on the top of the housing H of the dart game apparatus  100  as illustrated in  FIG. 2 . The camera unit  150  may include one or more cameras  151  to  153  which may photograph the dart target  110  and the throw line. The image photographed through the camera unit  150  may be transferred to the memory  180 . In some embodiments, only some of the motion pictures photographed by the camera unit  150  may be finally stored in the memory  180  or transferred to the server  300  (see  FIG. 3 ) through the network connection unit  160 . 
     Although not illustrated in  FIG. 2 , an infrared camera unit (not illustrated) may be installed above the housing of the dart game apparatus  100  and on a ceiling and left and right walls of a space in which the dart game apparatus  100  is installed.

       FIG. 4  is a flowchart for providing a dart game depending on a hitting area of a dart pin according to an exemplary embodiment of the present disclosure. 
     Hereinafter, a process for providing the dart game according to the hitting area of the dart pin will be described in brief. 
     According to the exemplary embodiment of the present disclosure, the dart game apparatus  100  or the dart game server  300  may judge the hitting locations of one or more dart pins which stick in the dart target (S 401 ). The hitting location of the dart pin may be judged based on the location identification module included in the dart pin. Alternatively, the hitting location of the dart pin may be judged based on the receiving groove of the dart target corresponding to the dart pin which sticks. 
     According to the exemplary embodiment of the present disclosure, the hitting area of the dart pin may be calculated based on the hitting location of the dart pin, which is judged through step  401  ( 403 ). This will be described below in more detail in  FIG. 5 . 
     According to the additional exemplary embodiment of the present disclosure, the dart game score may be calculated based on the hitting area calculated through step  403  and a predetermined logic ( 405 ). 
     The score calculated through step  405  is transmitted to the dart game apparatus  100  and a user device (not illustrated) which are communicatable with the dart server  300  (see  FIG. 3 ) and the network  200  to be provided to the dart game player ( 407 ). The score may be intuitively expressed by a text (script) and/or a graphic interface, etc. 
     Through the aforementioned process, various dart game modes according to the hitting area based on the location of the dart pin may be provided. Hereinafter, various dart game modes according to the hitting area based on the location of the dart pin will be described in detail. 
       FIG. 5A  exemplarily illustrates dart pins which stuck in a dart target. 
       FIG. 5B  exemplarily illustrates a first exemplary embodiment for calculating a hitting area based on a location of a dart pin. 
     Referring to  FIG. 5A , the sensing unit  120  and/or the location identification unit  121  may identify the locations of dart pins  510 ,  510 - 1  and  510 - 2  which stick in the dart target  110 . 
     Referring to  FIGS. 5A and 5B , a predetermined figure may be formed by connecting the hitting locations of the dart pins  510 ,  510 - 1  and  510 - 2  identified by the location identification unit  121 . Therefore, the hitting area of the dart pin thrown by the dart game player may be calculated by an area  520  of the formed figure. 
     In  FIGS. 5A and 5B , an exemplary embodiment using three dart pins is illustrated, but the number of dart pins may be a predetermined number such as 4, 6, or the like. In this case, the figured formed by the dart pin which sticks may also be a predetermined shape such as a quadrangle, a start, or the like. 
       FIG. 5C  exemplarily illustrates the dart pins which stick in the dart target. 
       FIG. 5D  exemplarily illustrates a second exemplary embodiment for calculating the hitting area based on the location of the dart pin. 
     Referring to  FIGS. 5C and 5D , the hitting locations of the dart pins  550 ,  550 - 1  and  550 - 2  may be identified based on the receiving grooves of the dart target, which correspond to the dart pins which stick, respectively. The hitting areas may be calculated based on segments  521 ,  523 , and  525  of the dart target, which correspond to the dart pins  550 ,  550 - 1 , and  550 - 2  which stick the dart target  110  identified by the location identification unit  121 . 
     For example, the hitting areas may be calculated by the sum of respective areas of the segments  521 ,  523 , and  525  of the dart target, which correspond to the dart pins  550 ,  550 - 1 , and  550 - 2 . Alternatively, in general, since the areas of the segments of ‘bullseye area’, ‘double area’, and ‘triple area’ of the dart target are small, a largest area is excluded among the segments hit per hitting opportunity which the dart game player has by reflecting the small areas to calculate the hitting areas. 
     Hereinafter, the present specification presents various dart game modes based on the hitting area of the predetermined figure formed by connecting the hitting locations of the identified dart pins by referring to  FIGS. 5A to 5D . 
       FIG. 6  exemplarily illustrates a first exemplary embodiment of a dart game mode which may be provided to a player. 
     Referring to  FIG. 6 , the hitting area of the dart pin formed by the dart game player may be a triangle  610  or a quadrangle  620 . Although not illustrated, the hitting area of the dart pin formed by the dart game player may be a star shape. 
     That is, when the dart pin may be thrown three times per hitting opportunity of the dart game player, a maximum of three dart pins may stick in the dart target  110 . Therefore, the triangle  610  may be formed as the hitting area. 
     Furthermore, when the dart pin may be thrown four times per hitting opportunity of the dart game player, a maximum of four dart pins may stick in the dart target  110 . Therefore, the quadrangle  620  may be formed as the hitting area. 
     Alternatively, since the dart game player may connect and form the hitting area until the game ends, even though the dart pin may be thrown three times per hitting opportunity of the dart game player, the quadrangle  620 , a pentagon (not illustrated), and a star shape (not illustrated) may be formed as the hitting area. Further, in the case of a 2:2 play mode or 2:2:2 play mode, the hitting area may be continuously formed. 
     Through the aforementioned contents, various dart game play modes by the scoring method according to the hitting area based on the location of the dart pin may be presented. Therefore, the entertainment elements of the dart game may be increased. 
       FIG. 7  exemplarily illustrates a second exemplary embodiment of the dart game mode which may be provided to the player. 
     Referring to  FIG. 7 , it may be verified that hitting areas  710 ,  720 , and  730  formed in the dart target  110  are areas generated by connecting the hitting locations of the dart pins thrown by the dart game player. In more detail, it may be verified that the hitting area  710  is formed by connecting hitting locations  701 ,  703 , and  705  of the dart pins. Further, it may be verified that the hitting area  720  is formed by connecting the hitting locations  701 ,  703 , and  707  of the dart pins. It may be verified that the hitting area  730  is formed by connecting hitting locations  701 ,  703 , and  709  of the dart pins. That is, it may be verified that the hitting area  730  has the largest hitting area and the hitting area  710  has the smallest hitting area. 
     Based on the predetermined logic according to the exemplary embodiment of the present disclosure, as the hitting area formed by the dart pin increases, the additional point may be granted. 
     That is, as the additional point granted to the hitting area  730 , an additional point which is larger than the additional point granted to the hitting area  710  may be granted. Further, the additional point granted to the hitting area  710 , which is smaller than the additional point granted to the hitting area  720  may be granted. 
     The aforementioned predetermined logic may be characterized in that as the hitting area formed by the dart pin increases, the additional point is granted. 
     On the contrary, the predetermined logic may be characterized in that as the hitting area formed by the dart pin decreases, the additional point is granted. This will be described below in  FIG. 8 . 
       FIG. 8  exemplarily illustrates a third exemplary embodiment of the dart game mode which may be provided to the player. 
     Referring to  FIG. 8 , it may be verified that hitting areas  810 ,  820 , and  830  formed in the dart target  110  are areas generated by connecting the hitting locations of the dart pins thrown by the dart game player. In particular, it may be verified that the hitting area  810  has the largest hitting area and the hitting area  830  has the smallest hitting area. 
     Based on the predetermined logic according to the exemplary embodiment of the present disclosure, as the hitting area formed by the dart pin decreases, the additional point may be granted. 
     That is, as the additional point granted to the hitting area  830 , an additional point which is larger than the additional points granted to the hitting areas  810  and  820  may be granted. This reflects that advanced training is required in detailed hitting, and as a result, a game mode such as hitting a smaller and smaller area, or the like may be provided. 
       FIG. 9  exemplarily illustrates a fourth exemplary embodiment of the dart game mode which may be provided to the player. 
     Referring to  FIG. 9 , it may be verified that hitting areas  910  and  920  formed in the dart target  110  are areas generated by connecting the hitting locations of the dart pins thrown by the dart game player. In particular, it can be seen that the hitting area  920  having a ‘bullseye  901 ’ which a dead center area of the dart target  110  as an apex is generated. 
     Based on the predetermined logic according to the exemplary embodiment of the present disclosure, when the hitting area is formed at a predetermined location of the dart target by the thrown dart pin, a weighted value may be granted. 
     That is, the dart game apparatus  100  (see  FIG. 1 ) may present the dart game player to directly hit the dart pin at a specific location of the dart target  110  in order to form the hitting area by the thrown dart pin. For example, the dart game apparatus  100  may present the bullseye  901  as one apex forming the hitting area. 
     Referring to  FIG. 9 , it may be verified that in the hitting area  910 , the bullseye  901  may not be directly hit and in the hitting area  920 , the bullseye  901  is directly hit. Therefore, since the additional points granted to the hitting areas  910  and  920 , respectively are different from each other even though widths of the hitting areas  910  and  920  are the same as each other, different scores may be calculated. That is, in this case, a score which is larger than the score of the hitting area  910  may be granted to the hitting area  920 . 
     Additionally, when the hitting areas formed by the thrown dart pins include the predetermined location of the dart target, the weighted value may be granted. For example, since the formed hitting area  910  includes the bullseye  901  therein in the case of the hitting area  910 , the weighted value may be granted to the hitting area  910 . 
       FIG. 10  exemplarily illustrates a fifth exemplary embodiment of the dart game mode which may be provided to the player. 
     Referring to  FIG. 10 , it may be verified that a hitting area  1001  formed by the dart target  110  is an area generated by connecting the hitting locations of the dart pins thrown by the dart game player. 
     In more detail, the hitting area  1001  illustrated in  FIG. 10  may be a hitting area formed by the dart pin thrown by the first player. Further, a dart pin  512  may be a dart pin thrown by the second player. 
     Based on the predetermined logic according to the exemplary embodiment of the present disclosure, the hitting area formed by the dart pin thrown by the first player may be determined as a score area in which the score is granted only to the first player within a predetermined period. 
     That is, as illustrated in  FIG. 10 , when the dart pin  512  thrown by the second player sticks in a target area included in the hitting area  1001  formed by the dart pin thrown by the first player, the score may not be provided to the second player. Therefore, even though the second player directly hits the dart pin at a single  7  area, 7 points may not be added to a dart score of the second player. 
     Efficacy of the predetermined logic may be maintained only within a predetermined period. For example, throwing the dart pin three times may be set as the predetermined period. Alternatively, performing a dart hitting opportunity of throwing the dart pin three times three times may be set as the predetermined period. Alternatively, a period from the start of the game up to the end of the game may be set as the predetermined period. 
     Therefore, when performing a dart hitting opportunity of throwing the dart pin three times three times is set as the predetermined period, the efficacy of the score area formed previously may be lost in the case where the dart throwing opportunity of throwing the dart pin is performed for the fourth time. 
     That is, in the case where the dart hitting opportunity of throwing the dart pin three times is performed for the fourth time, the hitting area  1001  formed by the dart pin thrown by the first player is not determined as a unique score acquisition area of the first player any longer. Therefore, in the case where the dart hitting opportunity of throwing the dart pin three times is performed for the fourth time, the second player may throw the dart pin so as to acquire the hitting area  1001  formed by the dart pin previously thrown by the first player as his/her score acquisition area. 
     Based on the predetermined logic according to the additional exemplary embodiment of the present disclosure, when the dart pin thrown from the second player sticks in the hitting area formed by the dart pin thrown by the first player, the corresponding hitting area may be determined as a score area where the penalty is granted to the second player. 
     That is, when the dart pin  512  thrown by the second player directly hits the hitting area included in the hitting area  1001  formed by the dart pin thrown by the first player, the penalty may be granted to the second player. That is, even though the second player directly hits the dart pin at the single  7  area, 7 points may not be added to the dart score of the second player and −7 points may be granted as the penalty. The aforementioned penalty is just an example according to the exemplary embodiment of the present disclosure and the penalty may be granted by various methods. 
     According to the additional exemplary embodiment of the present disclosure, the hitting areas formed by the three dart pins thrown by the first player may be determined as a hitting area in which the second player may acquire the score by throwing the dart pin within a predetermined period. For example, only when the dart pin thrown by the second player enters an area set by the first player, the score may be granted. That is, referring to  FIG. 10 , only when the dart pin  512  thrown by the second player sticks in the hitting area  1001  formed by the dart pin thrown by the first player, the score may be granted. Further, after a predetermined period, the second player may be allowed to generate the target area where the first player may acquire the score to cause the dart game player to induce an interest. 
     In more detail, the first player throws the dart pin three times or more, and as a result, the hitting area for the second player may be formed. Then, only when the second player throws the dart pin within the area formed by the first player, the score corresponding to the corresponding segment may be provided to the second player. After one turn ends, the second player throws the dart pin three times or more, and as a result, the hitting area for the first player may be formed. Then, only when the first player throws the dart pin within the area formed by the second player, the score corresponding to the corresponding segment may be provided to the first player. 
     Therefore, from the viewpoint of the player that forms the hitting area of the dart pin, a follow-up player may not acquire the score by minimally reducing the area and the follow-up player needs to throw the dart pin within the formed area, and as a result, the dart game mode according to an aspect of the present disclosure may further increase a fun of the dart game. 
       FIG. 11  exemplarily illustrates a sixth exemplary embodiment of the dart game mode which may be provided to the player. 
     Referring to  FIG. 11 , it may be verified that a hitting area  1101  formed by the dart target  110  is an area generated by connecting the hitting locations of the dart pins thrown by the dart game player. 
     Based on the predetermined logic according to the additional exemplary embodiment of the present disclosure, the hitting area formed by the dart pin thrown by the first player may be determined as a score area in which the weighted value is granted to the first player within a predetermined period. 
     That is, when a dart pin  612  thrown by the first player directly hits the target area included in the hitting area  1101  formed by the dart pin thrown by the first player, the weighted value may be granted to the first player. That is, even though the first player directly hits the dart pin at the single  7  area, 7 points or more may be added to the dart score of the first player. 
     As described above, according to the present disclosure, the score of the dart game is calculated in a more entertaining manner to enhance a pleasure of the dart game player. Further, various dart game methods may be proposed.
