CROSS-REFERENCE TO RELATED APPLICATION AND CLAIM OF PRIORITY 
       [0001]    The present application is related to and claims priority from and the benefit under 35 U.S.C. §119(a) of Korean Patent Application No. 10-2013-0105175, filed on Sep. 3, 2013, which is hereby incorporated by reference for all purposes as if fully set forth herein. 
       TECHNICAL FIELD 
       [0002]    The present disclosure relates generally to a dual monitor system and method, and more particularly to a dual monitor system and method using a terminal including a touch screen and a computing device including a screen. 
       BACKGROUND 
       [0003]    Electronic devices including recently developed computers can provide users with various functions by executing application programs through processors. As various application programs have been developed and specifications of electronic devices have been improved, the electronic device can simultaneously perform several tasks and connect a main body of the electronic device to two or more screens to meet a multitasking environment, so as to support a dual monitoring mode in which respective task environments are displayed. 
         [0004]    Meanwhile, various terminals are used as electronic devices which can be carried by users today. According to the development of technologies, the electronic devices in a comprehensive multimedia device type having complex functions such as not only a voice call but also a video call, taking a picture or a video, reproducing music and a video file, receiving a broadcast, playing a game and wireless Internet and the like are released. Specifications of a processor installed in the terminal are being improved at an alarming rate and terminals which provide light and large screens within a portable range are being developed. Further, a terminal including a touch screen is currently provided to increase the interface convenience of the user. 
         [0005]    A portable terminal and a computing device provided to process various tasks in a fixed location may provide the user with different functions as necessary. Accordingly, the user may require simultaneously use of the terminal and the computing device, but it is inconvenient for the user to separately control the terminal and the computing device. 
         [0006]    Therefore, a method of supporting a dual monitoring mode of the computing device through interworking between the terminal and the computing device and also executing a function of the terminal is required.

     DETAILED DESCRIPTION 
       [0029]    FIGURES  1 A through  7 , discussed below, and the various embodiments used to describe the principles of the present disclosure in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged electronic devices. Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the accompanying drawings. It is noted that, where possible, the same reference numerals are designated to the same components in the accompanying drawings. Further, a detailed description of a known function and configuration which may make the subject matter of the present disclosure unclear will be omitted. 
         [0030]    Prior to the detailed description through embodiments, a computing device described in the specification and drawings may include all electronic devices which provide a user with various functions by executing application programs through a process stored in a memory. 
         [0031]    A “dual monitor mode” used in the specification and drawings refers to a case where a task environment of an application program executed by the computing device is implemented on not only a screen of the computing device but also a touch screen of a terminal connected to the computing device. That is, the “dual monitor mode” refers to a case where the touch screen of the terminal operates as an additional screen of the computing device. 
         [0032]    A “single monitor mode” described in the specification and drawings refers to a case where functions of the terminal and the computing device executed by corresponding processors are independently displayed on respective screens in a state where the terminal and the computing device are connected to each other. That is, the “single monitor mode” refers to a case where a task environment of the terminal is implemented on the touch screen of the terminal and a task environment of the computing device is implemented on the screen of the computing device. 
         [0033]      FIGS. 1A and 1B  illustrate a dual monitor system according to an embodiment of the present disclosure. 
         [0034]    The dual monitor system includes a terminal  100  and a computing device  200  as illustrated in  FIGS. 1A and 1B . The terminal  100  can include a touch screen and display a user interface on the touch screen. The computing device  200  can include a screen and display an application program window executed by the computing device on the screen. The terminal  100  and the computing device  200  are executed by processors stored in respective memories thereof. 
         [0035]    A dual monitor system connects the terminal  100  and the computing device  200  to allow the terminal  100  and the computing device  200  to exchange signals. The terminal  100  and the computing device  200  can be connected to each other through a wire or wirelessly connected to each other by using a wireless network. Meanwhile, a connection device  300   a  for connecting one side of the terminal  100  and one side of the screen of the computing device  200  can be further included as illustrated in  FIG. 1A , or a connection device  300   b  for fixing the terminal  100  and connecting the terminal  100  to the computing device  200  can be further included for convenience of the user. Embodiments of the present disclosure include all methods of disposing the terminal  100  and the computing device  200  such that the user can have secured view for the touch screen of the terminal  100  and the screen of the computing device  200  can be secured. 
         [0036]      FIG. 2  illustrates a detailed embodiment of the terminal  100  according to an embodiment of the present disclosure. 
         [0037]    The terminal  100  can include a processor  210 , a touch screen  220 , and an input/output unit  230 . The processor  210  can control general operations of the terminal  100 . That is, the processor  210  can perform a function of providing a user interface to the touch screen  220 , receiving a user input through the user interface, and executing a corresponding application program. The processor can receive a user input through the touch screen  220  and also receive a user input through the input/output unit  230 . 
         [0038]    The touch screen  220  can receive a touch input by the user and also receive an output signal from the processor  210  or the input/output unit  230  and display an output screen. That is, the touch screen  220  can display a user interface and an executed application program and the displayed user interface and application program can be intuitively controlled by a touch input on the touch screen  220  by the user. 
         [0039]    The input/output unit  230  is provided to connect the terminal  100  and an external device, for example, the computing device  200 . When the input/output unit  230  is connected to the computing device  200 , an output signal of the processor  210  can be transmitted to the screen of the computing device  200 , a user input signal by the computing device  200  can be transmitted to the processor  210  of the terminal  100 , and an output signal of the computing device  200  can be transmitted to the touch screen  230  of the terminal  100 . 
         [0040]    The dual monitor system according to the embodiment of the present disclosure can include a dual monitor controller  400  for operating the terminal  100  and the computing device  200  in a dual monitor mode. The dual monitor controller  400  is connected to the terminal  100  and the computing device  200  to control switching to the dual monitor mode or the single monitor mode. At this time, the dual monitor controller  400  can be located outside the terminal  100  as illustrated in  FIG. 2 , but can be located inside the terminal  100 . A dual monitor controller  400  which will be described below can be located inside the computing device  200 . That is, the dual monitor controller  400  should be interpreted based on the function of the configuration rather than an arrangement of the configuration in the present disclosure. 
         [0041]      FIG. 3  illustrates a detailed embodiment of the computing device  200  according to an embodiment of the present disclosure. 
         [0042]    The computing device  200  can include a main body  310  and peripherals  320  to  340 . The main body can include a processor  311  for controlling general operations of the computing device  200  and an input/output unit  312  provided to connect the peripherals  320  to  340  and the terminal  100 . 
         [0043]    A screen  320 , a keyboard  330 , and a mouse  340  transmit/receive signals through the input/output unit  312 . The screen  320  can receive an output signal of the processor  311  and an output signal of the terminal  100  through the input/output unit  312  and display an output screen. The keyboard  330  and the mouse  340  are user input means and input signals input by the keyboard  330  and the mouse  340  can be transmitted to the processor  311  and the terminal  100  through the input/output unit  312 . 
         [0044]    The dual monitor controller  400  is connected to the terminal  100  and the computing device  200  to control switching to the dual monitor mode or the single monitor mode. The dual monitor controller  440  can be located outside or inside the computing device  200  as described above. 
         [0045]      FIGS. 4A to 4C  illustrate that a dual monitor system operates in the dual monitor mode according to an embodiment of the present disclosure. Referring to  FIG. 4A , the terminal  100  and the computing device  200  are connected through a wire or wirelessly, using any suitable communication technologies including cellular, Wifi, Bluetooth, and Near Field Technologies (NFC). In some embodiments, the terminal  100  and the computing device  200  are attached to each other by a connection device  300 . 
         [0046]    Each of the terminal  100  and the computing device  200  operates in the single monitor mode. The terminal  100  displays a user interface  410   a  on the touch screen. The computing device  200  displays one or more application program windows  420   a  and  430   a  being executed on the screen. 
         [0047]    Thereafter, as illustrated in  FIG. 4B , the application program window  420   a  displayed on the screen of the computing device  200  is dragged using a mouse connected to the computing device  200  and moved in a direction in which the terminal  100  is located by a predetermined distance. At this time, the direction in which the terminal  100  is located can be preset by the user. When the application program window  420   a  is dragged by a threshold or more, switching to the dual monitor mode is made as illustrated in  FIG. 4C . That is, the dragged application program window  420  disappears from the screen of the computing device  200  and the application program window  420   b  is generated on the touch screen of the terminal  100 . That is, the touch screen of the terminal  100  operates as one of a dual screen of the computing device  200 . Meanwhile, a user interface  410   b  of the terminal  100  is copied to the screen of the computing device  200 . Accordingly, even in the dual monitor mode, the user can execute a function of the terminal  100  through the user interface  410   b  of the terminal  100  copied to the screen of the computing device  200 . 
         [0048]    Referring to  FIG. 5A , when the dual monitor system is in the single monitor mode, a mouse cursor  500  can move on the screen of the computing device  200  and the touch screen of the terminal  100  through a control of the mouse by the user. That is, in the single monitor mode, through a mouse and a keyboard corresponding to input means connected to the computing device  200 , a function of the terminal  100  can be executed on the screen of the terminal  100  or a function of the computing device  200  can be executed on the screen of the computing device  200 . 
         [0049]    Referring to  FIG. 5B , when the dual monitor system is in the dual monitor mode, the touch screen of the terminal  100  operates as one of the dual screen of the computing device  200 . That is, the mouse cursor  500  can move on the touch screen of the terminal  100  as well as on the screen of the computing device  200 , so as to control the application program window executed by the computing device  200 . Further, the user interface  410   b  of the terminal  100  is copied to the screen of the computing device  200 . The user can execute the function of the terminal  100  through the copied user interface  410   b.  That is, in the dual monitor mode, through the mouse and the keyboard corresponding to the input means connected to the computing device  200 , the application program window executed by the computing device  200  can be controlled on both the touch screen of the terminal and the screen of the computing device  200  and the function of the terminal  100  can be executed on the copied user interface  410   b.    
         [0050]    Meanwhile, according to an embodiment of the present disclosure, since the terminal  100  and the computing device  200  are connected to each other, a file displayed on the touch screen of the terminal  100  can be copied to the computing device  200  by dragging the file through a mouse cursor  500  and a file displayed on the screen of the computing device  200  can be copied to the terminal  100  by dragging the file. 
         [0051]      FIGS. 6A to 6C  illustrate a method in which a dual monitor system ends a dual monitor mode according to an embodiment of the present disclosure. 
         [0052]    Referring to  FIG. 6A , the dual monitor system is in a state where the dual monitor mode is operated. That is, the terminal  100  is connected to the computing device  200  and the touch screen of the terminal  100  operates as one of the dual screen of the computing device  200 . The user interface  410   b  of the terminal  100  is copied to the screen of the computing device  200 . 
         [0053]    Thereafter, as illustrated in  FIG. 6B , the user interface  410   b  of the terminal  100  copied to the screen of the computing device  200  is moved to the terminal  100 . For example, the copied user interface  410   b  can be dragged using a mouse. Since the touch screen of the terminal  100  and the screen of the computing device  200  operate in the dual monitor mode, the copied user interface  410   b  can be moved to the touch screen of the terminal  100  according to the drag. According to an embodiment, only when an application program window executed by the computing device  200  does not exist on the touch screen of the terminal  100 , the movement of the copied user interface  410  to the touch screen of the terminal  100  is allowed. That is, when the touch screen of the terminal  100  displays a function actually executed by the computing device  200  in the dual monitor mode, it can be preset to not end the dual monitor mode. 
         [0054]    Alternatively, according to another embodiment, when an application program window executed by the computing device  200  is displayed on the touch screen of the terminal  100 , if the copied user interface  410  is moved to the touch screen of the terminal  100 , the corresponding application program window can be displayed on the screen of the computing device  200 . 
         [0055]    As illustrated in  FIG. 6C , when the user interface  410   a  reaches the terminal  100 , the dual monitor mode ends. That is, each of the touch screen of the terminal  100  and the screen of the computing device  200  operates in the single monitor mode. 
         [0056]      FIG. 7  is a flowchart illustrating a dual monitor method according to an embodiment of the present disclosure. 
         [0057]    The dual monitor method illustrated in  FIG. 7  will be described below with reference to  FIGS. 4 and 6 . 
         [0058]    First, the terminal  100  and the computing device  200  are connected to each other in step S 710 . Each of the connected terminal  100  and computing device  200  performs a task in the single monitor mode in step S 720 . That is, the terminal  100  provides a user interface through the touch screen of the terminal  100  and the computing device  200  provides an application program window through the screen of the computing device  200 . 
         [0059]    In step S 730 , the terminal  100  and the computing device  200  are switched to the dual monitor mode. Specifically, when the application program window  420   a  displayed on the screen of the computing device  200  is moved to the touch screen of the terminal  100  in step S 731 , the user interface  410   b  of the terminal  100  is copied to the screen of the computing device  200  in step S 732 . Thereafter, in step S 740 , the terminal  100  and the computing device  200  perform tasks in the dual monitoring mode. 
         [0060]    In step S 750 , the terminal  100  and the computing device  200  end the dual monitor mode. Specifically, the user interface  410   b  copied to the screen of the computing device  200  is moved to the touch screen of the terminal  100 . Thereafter, in step S 760 , the terminal  100  and the computing device  200  perform tasks in the single monitor mode. 
         [0061]    Although the present disclosure has been described with an exemplary embodiment, various changes and modifications may be suggested to one skilled in the art. It is intended that the present disclosure encompass such changes and modifications as fall within the scope of the appended claims.
