The components shown in FIG. 1 are not essential for implementing a mobile terminal, so that the mobile terminal described herein may have more or fewer components than the components listed above.

More specifically, the display unit 140 displays (outputs) information processed by the mobile terminal 100, among the components. For example, the display unit 140 may display execution screen information of an application program driven by the mobile terminal 100, or UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information .

Also, the display unit 140 may be configured as a stereoscopic display unit for displaying a stereoscopic image.

In the stereoscopic display unit, a three-dimensional display system such as a stereoscopic system (glasses system), an autostereoscopic system (no-glasses system), and a projection system (holographic system) can be applied.

Meanwhile, the display unit 140 may have a mutual layer structure with the touch sensor 120 or may be integrally formed to realize a touch screen. Such a touch screen may function as a user input unit for providing an input interface between the mobile terminal 100 and a user and may provide an output interface between the mobile terminal 100 and a user.

On the other hand, the touch sensor 120 can be configured to detect the proximity of an object due to a change in electric field along the proximity of an object having conductivity (hereinafter referred to as a conductor).

The touch sensor uses at least one of various touching methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, and a magnetic field type to detect a touch (or touch input) applied to the touch screen Detection.

The touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and then transmits the corresponding data to the controller 110. Accordingly, the control unit 110 can know which area of the display unit 140 is touched or the like. Here, the touch controller may be a separate component from the control unit 110, and may be the control unit 110 itself.

On the other hand, the control unit 110 may perform different controls or perform the same control according to the type of the touch object, which touches the touch screen (or a touch key provided in other than the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

The mobile terminal 100 may operate in association with a web storage that performs a storage function of the memory unit 130 on the Internet.

In addition, the memory unit 130 stores data supporting various functions of the mobile terminal 100. The memory unit 130 may store a plurality of application programs or applications driven by the mobile terminal 100, data for operation of the mobile terminal 100, and commands. At least some of these applications may be downloaded from an external server via wireless communication. Also, at least a part of these application programs may exist on the mobile terminal 100 from the time of shipment for the basic functions (e.g., telephone call receiving function, message receiving function, and calling function) of the mobile terminal 100. Meanwhile, the application program may be stored in the memory unit 130, installed on the mobile terminal 100, and may be operated by the control unit 110 to perform the operation (or function) of the mobile terminal.

The control unit 110 controls an operation related to an application program and an overall operation of the mobile terminal 100. [ For example, when the state of the mobile terminal meets a set condition, the controller 110 may execute or release a lock state for restricting input of a user's control command to applications.

In addition, the control unit 110 performs control and processing related to voice communication, data communication, video call, and the like, or performs a pattern recognition process capable of recognizing handwriting input or drawing input performed on the touch screen as characters and images, respectively . Further, the controller 110 may control any one or a plurality of the above-described components in order to implement various embodiments described below on the mobile terminal 100 according to the present invention.

The control unit 110 typically controls the overall operation of the mobile terminal 100, in addition to the operations associated with the application program. The control unit 110 may process or process signals, data, information, and the like input or output through the above-described components, or may drive an application program stored in the memory unit 130 to provide or process appropriate information or functions to the user .

In addition, the controller 110 may control at least some of the components illustrated in FIG. 1 to drive an application program stored in the memory unit 130. FIG. In addition, the controller 110 may operate at least two of the components included in the mobile terminal 100 in combination with each other for driving the application program.

Meanwhile, the power supply unit 150 receives external power and internal power under the control of the controller 110, and supplies power required for operation of the respective components. The power supply unit 150 may include a battery, the battery may be an internal battery configured to be chargeable, and may be detachably coupled to the terminal body for charging or the like.

Also, the power supply unit 150 may include a connection port, and the connection port may be configured as an interface through which an external charger for supplying power for charging the battery is electrically connected.

As another example, the power supply unit 150 may be configured to charge the battery in a wireless manner without using the connection port. In this case, the power supply unit 150 may use at least one of an inductive coupling method based on the magnetic induction phenomenon and a magnetic resonance coupling method based on the electromagnetic resonance phenomenon from an external wireless power transmission apparatus Power can be delivered.

At least some of the components may operate in cooperation with one another to implement a method of operation, control, or control of a mobile terminal according to various embodiments described below. In addition, the operation, control, or control method of the mobile terminal may be implemented on the mobile terminal by driving at least one application program stored in the memory unit 130.

Meanwhile, the touch sensor 120 according to the embodiment of the present invention can detect noise generated from the touch screen. For example, the noise may be a noise generated when the capacitance of the point where the conductor contacts with the touch screen is discharged due to contact with the conductor, when the conductor is in contact with the touch screen.

The touch sensor 120 may include a sensing unit 122 for sensing the touch input when the touch input is sensed on the touch screen. The sensing unit 122 may be embedded in the touch sensor 120 or integrated with the touch sensor 120. Alternatively, the sensing unit 122 may be provided outside the touch sensor 120 in addition to the touch sensor 120.

The control unit 110 of the mobile terminal 100 according to an embodiment of the present invention may perform a data exchange according to a selection of a user or a data exchange according to an embodiment of the present invention, And can operate in a data reception mode.

If the controller 110 operates in a data transmission mode, the controller 110 may apply power to the touch sensor 120 according to a predetermined pattern generated from data to be transmitted. Accordingly, the touch sensor 120 can be powered on / off according to the pattern. In this case, if the conductor is in contact with the touch sensor 120 according to the embodiment of the present invention, when the touch sensor 120 is powered on, A change in capacitance may occur. When the change in the capacitance occurs, noise due to contact between the touch sensor 120 and the conductor may be generated.

On the other hand, the noise can be conducted along the conductor. This is because the noise is also a type of electrical signal. Thus, the noise can be conducted along the conductor. The noise may be transmitted in a pattern corresponding to the data to be transmitted. This is because, when the controller 110 operates in the data transfer mode as described above, the noise is generated only when the power is applied to the touch sensor in a predetermined pattern according to the data to be transmitted and accordingly the power is turned on.

On the other hand, if the controller 110 operates in the data receiving mode, the controller 110 can sense the noise from the conductor contacted to the touch sensor 120. Here, the noise may have a certain pattern as described above. In this case, the controller 110 may generate data corresponding to the sensed noise. For example, the controller 110 may generate a binary code of 1 or 0 corresponding to the noise, based on whether the intensity of the detected noise is higher than a predetermined level.

In the following, various embodiments may be embodied in a recording medium readable by a computer or similar device using, for example, software, hardware, or a combination thereof.

Hereinafter, embodiments related to a control method that can be implemented in a mobile terminal configured as above will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

2A and 2B are exemplary diagrams showing an example of a mobile terminal related to the present invention.

For example, the mobile terminal 100 according to the embodiment of the present invention can operate in both a data transmission mode and a data reception mode, as described above. 2A and 2B, one mobile terminal 100a operates in a data transmission mode (transmitting terminal) 100a and two mobile terminals 100a and 100b operate in a data reception mode using the two mobile terminals 100a and 100b according to the embodiment of the present invention. (Receiving terminal: 100b).

2A, the transmitting terminal 100a and the receiving terminal 100b are in a state in which one side 202 and 204 of the conductor 200 are in contact with each other on the touch screen. In this state, the control unit of the transmitting terminal 100a generates a power supply pattern corresponding to the data to be transmitted and applies power to the touch sensor 120a of the transmitting terminal 100a according to the generated power supply pattern. Here, the power application pattern corresponding to the data to be transmitted may be a pattern for turning on or off the power applied to the touch sensor 120a according to the binary code of the data to be transmitted.

When power is applied to the touch sensor 120a from the control unit of the transmitting terminal 100a according to the generated pattern, the touch sensor 120a of the transmitting terminal 100a and the touch sensor 120a contacting the touch sensor 120a, Noises may be generated between one surface 202 of the conductor 200 according to a pattern of a power source applied to the touch sensor 120a. As described above, since the power to the touch sensor 120a can be turned on / off according to the generated power application pattern, when the power is applied to the touch sensor 120a, the noise is generated, This is because the noise may not be generated when power is not applied to the sensor 120a.

On the other hand, such a certain pattern of noise may be conducted along the conductor 200 from one side 202 to the other side 204. This is because the noise is also an electrical signal. Accordingly, the noise generated by the touch sensor 120a of the transmitting terminal 100a may be transmitted along the conductor 200 and transmitted to the touch sensor 120b of the receiving terminal 100b.

Meanwhile, the control unit of the receiving terminal 100b may sense a noise signal transmitted from the conductor 200 through the touch sensor 120b. In this case, the control unit of the receiving terminal 100b may recognize the pattern in which the noise is conducted according to whether the noise is detected as a binary code, and generate data corresponding thereto. Therefore, the same data as the data to be transmitted from the transmitting terminal 100a can be generated at the receiving terminal 100b, and thus the data of the transmitting terminal 100a can be transmitted to the receiving terminal 100b.

Meanwhile, since the touch sensor 120b of the receiving terminal 100b is in an operating state of receiving data from the transmitting terminal 100a, the state in which the touch sensor 120b is powered on is maintained during the data transmission . In this case, noise may also occur between the other surface 204 of the conductor and the touch sensor 120b of the receiving terminal 100b. In this case, the noise generated between the other surface 204 of the conductor and the touch sensor 120b of the receiving terminal 100b may be constantly generated during the data transmission.

In this case, if noise of a certain pattern is transmitted through the conductor, the noise generated from the one surface 202 of the conductor 200 and the noise generated from the other surface 204 of the conductor 200 Noise superimposed noise can be conducted. In this case, when the touch sensor 120a of the transmitting terminal 100a is supplied with power, the intensity of the noise sensed by the conductor 200 is lower than the power of the touch sensor 120a of the transmitting terminal 100a And can be conducted through the conductor 200 with a stronger intensity than when not applied.

In this case, the receiving terminal 100b recognizes the pattern in which the noise is conducted based on the intensity of the noise transmitted from the conductor 200 as a binary code, and transmits data corresponding to the data transmitted from the transmitting terminal 100a Can be generated.

In FIG. 2A, a separate conductor connecting between the two mobile terminals 100a and 100b is described. However, it is needless to say that any such conductor 200 can be used as long as an electric signal can be transmitted. For example, the conductor 200 may use a part of the user's body.

FIG. 2B shows an example in which a part of a user's body is used as a conductor.

Referring to FIG. 2B, FIG. 2B shows an example in which the hand 250 of the user performs the role of the conductor 200 instead of the conductor 200. In this case, one of the fingers 252 of the user may be one side 202 of the conductor 200 and the other one 254 of the user may be the other side 204 of the conductor 200 have. As shown in FIG. 2B, when a user touches one of the finger 252 to the transmitting terminal 100a, the touch sensor 120a of the transmitting terminal 100a and the one of the finger 252 May be conducted along the user ' s hand (250).

In this state, when the user touches the other finger 254 to the touch sensor 120b of the receiving terminal 100b, the noise conducted through the user's hand 250 is transmitted to the touch sensor 120b of the receiving terminal 100b So that data of the transmitting terminal 100a can be transmitted to the receiving terminal 100b, as described above.

FIG. 3 is a flowchart illustrating an operation procedure of the mobile terminal according to the present invention.

Referring to FIG. 3, the controller 110 of the mobile terminal 100 determines an operation mode of the mobile terminal 100 according to an exemplary embodiment of the present invention (S300). Here, the controller 110 may determine an operation mode of the mobile terminal 100 according to a user's selection, or an operation mode may be determined according to a data transmission / reception state.

If it is determined in operation S200 that the operation mode is the data transmission mode, the controller 110 enters the data transmission mode (S310). In step S310, the controller 110 may select the data to be transmitted from the user or perform a pairing operation with the receiving terminal to which the data is to be transmitted.

In step S310, when the preparation for transmitting data such as selection of data to be transmitted and pairing with a receiving terminal is completed, the controller 110 generates a power-on pattern corresponding to the data selected for transmission S312). The power-on pattern may be generated in a form corresponding to a binary code of the data to be transmitted. That is, if the binary code of the data to be transmitted is '0', the controller 110 turns off the power, and if the binary code of the data to be transmitted is '1', the controller 110 turns on the power The power-on pattern can be generated in a form that allows the power-on pattern to be generated. If the binary code of the data to be transmitted is '10001010111', for example, the control unit 110 outputs 'ON', 'OFF', 'OFF' On ',' on ',' on ',' off ',' on ',' on ', and' on '

Meanwhile, when the power application pattern is formed, the controller 110 controls power to be applied to the touch sensor 120 according to the generated power application pattern (S314). Accordingly, power is applied to the touch sensor 120 according to the generated power application pattern, and noises are generated due to conductors contacting the touch sensor 120 whenever the power is turned on.

If it is determined in operation S300 that the determined operation mode is the data reception mode, the controller 110 enters the data reception mode (S320). The control unit 110 may perform a pairing operation with a transmitting terminal that transmits data and may apply power to the sensing unit 122 of the touch sensor 120 to transmit the touch sensor 120. [ The user may be ready to detect noise through the display 120.

In operation S320, the control unit 110 senses an electrical signal transmitted through the conductor contacting the touch sensor 120 (S322). Wherein the electrical signal to be conducted may be noise that is conducted through the conductor.

If an electrical signal is sensed through the conductor touching the touch sensor 120 in step S322, the controller 110 may generate data corresponding to the sensed state in step S324. For example, the controller 110 can detect the electrical signal, that is, whether noise is detected or the intensity of the noise, and convert the detected electrical signal into a binary code according to the detected state. For example, when the noise is detected, the control unit 110 outputs a value of '1'. If the noise is not detected, the control unit 110 outputs a value of '1' The binary code corresponding to the state in which the noise is detected can be generated with '0'. The generated binary code may correspond to data transmitted through the conductor.

In this case, when the noise is detected or the noise is detected as noise of a predetermined intensity or more, the detection state of the noise is set to '1' and the noise is detected as '0' Encoding may be determined by the terminal transmitting the data. That is, for example, when the terminal transmitting the data, that is, the transmitting terminal, turns on the touch sensor when the binary code of the data to be transmitted is '0', a power supply pattern to be applied to the touch sensor 120 The terminal receiving the data, that is, the receiving terminal, enters the operation mode for receiving the data in step S320 and acquires this information at the time of pairing with the transmitting terminal, thereby coding the state in which the noise is detected The method can be determined.

FIG. 4 illustrates an example of a noise generated according to a voltage pattern applied to a touch sensor and a code generated according to the noise in the mobile terminal according to the present invention.

4, an example of a power-on pattern generated by a terminal that transmits data, that is, a transmitting terminal, among a plurality of terminals exchanging data according to an embodiment of the present invention is shown It is.

Referring to FIG. 4A, when the binary code of data to be transmitted is '011100011001', power is applied to the touch sensor when the binary code is '1', and when power is applied to the touch sensor, Off state of the power supply pattern.

In this case, when power is applied to the touch sensor 120 according to the pattern shown in FIG. 4A, the touch sensor 120 generates noise due to the contacted conductor while the power is applied, If no voltage is applied, noise is not generated. Therefore, if the power is applied to the touch sensor 120 according to the power application pattern as shown in FIG. 4A, the noise generated may be similar to the power application pattern. FIG. 4 (b) shows an example in which noise is generated as described above.

On the other hand, when noise is generated as described above, the noise is also an electrical signal, so that the noise can be conducted along the conductor. Accordingly, when there is another terminal in contact with the conductor, the terminals can detect the noise.

In this case, the terminal (receiving terminal) that senses the noise can generate a binary code corresponding to the state in which the noise is detected, as mentioned in step S324. For example, as shown in FIG. 4 (c), the controller 110 can encode a state in which the noise is detected as 0 or 1 according to the intensity of the detected noise.

Accordingly, if noise such as that shown in FIG. 4 (b) is detected, the receiving terminal divides the time when the noise is detected into the time of the predetermined bit unit, and detects the intensity of the noise corresponding to each time unit 0 " or " 1 " In the receiving terminal, the same data as the data '011100011001' to be transmitted can be generated.

In the above description, it is mentioned that the transmitting terminal and the receiving terminal perform pairing before performing data exchange. Here, the 'pairing' may mean that the transmitting terminal and the receiving terminal synchronize with each other. Also, in this synchronization process, the transmitting terminal and the receiving terminal can be switched to an operation mode in which an operation mode transmits data or an operation mode in which data is received, respectively, based on the state of data transmitted or received, Exchangeable.

FIG. 5 is a flowchart illustrating an operation procedure including a synchronization process performed between a terminal operating in a data transmission mode and a terminal operating in a data reception mode, according to an exemplary embodiment of the present invention.

Referring to FIG. 5, when data transmission is determined, the transmitting terminal, i.e., the first terminal 100a, applies power to the touch sensor according to a predetermined synchronization pattern (500). Here, the synchronization pattern is for synchronizing with a receiving terminal at the time of data transmission, and may be preset with the receiving terminal. In the following description, FIG. 5 will be described with reference to the embodiment of the present invention shown in FIG. 2A.

In this case, the controller 110 of the first terminal 100a may determine an operation mode in a data transmission mode in order to transmit a signal corresponding to the synchronization pattern. Accordingly, power can be applied to the touch sensor 120a of the first terminal 100a according to the synchronization pattern, so that the noise corresponding to the synchronization pattern can be transmitted to the conductor 200 (502) .

Meanwhile, when the noise corresponding to the synchronization pattern is transmitted through the conductor, the second terminal 100b can sense the detected noise and code the sensed noise (504). In this case, the second terminal 100b may detect the noise corresponding to the synchronization pattern through the conductor 200, and the operation mode may be determined as the data reception mode until the sensed noise is coded. The controller of the second terminal 100b may determine whether the coded noise corresponds to a predetermined synchronization pattern (506).

Meanwhile, the controller of the second terminal 100b may determine the operation mode of the second terminal 100b according to the determination result of step 506. FIG. For example, if it is determined in step 506 that the detected pattern does not correspond to a preset synchronization pattern, the controller of the second terminal 100b determines that data transmission is not performed, The operation mode can be maintained as it is.

However, if it is determined in step 506 that the detected pattern corresponds to a predetermined synchronization pattern, the control unit of the second terminal 100b may transmit an operation state of the second terminal 100b to an operation mode You can switch. This is to transmit a response (ACK (Acknowledge) signal) to the first terminal 100a to notify that the second terminal 100b has received the synchronization signal transmitted by the first terminal 100a, for synchronization.

The controller of the second terminal 100b may switch the operation mode to the data transmission mode and apply power to the touch sensor 120b of the second terminal 100b in a pattern corresponding to the predetermined ACK signal (508). In this case, in the touch sensor 120b of the second terminal 100b, noise may occur in a pattern corresponding to the ACK signal with the contacted conductor 200, and the generated noise may be transmitted through the conductor 200 (510) to the first terminal 100a.

Meanwhile, the controller of the first terminal 100a may generate noise corresponding to the synchronization pattern at predetermined time intervals. That is, the controller of the first terminal 100a may apply power to the touch sensor 120a in a pattern corresponding to the synchronization pattern, and may switch the operation mode to the data reception mode. If the noise corresponding to the ACK signal is not detected from the conductor within a predetermined time, the operation mode is again switched to the data transmission mode and the noise corresponding to the synchronization pattern is generated again.

However, if a noise corresponding to the ACK signal is detected from the conductor 200 in contact with the touch sensor 100a within the predetermined time, the controller of the first terminal 100a may code the sensed noise 512 . The controller of the first terminal 100a may determine whether the coded noise corresponds to a predetermined ACK signal (514).

If it is determined in step 514 that the noise detected by the conductor does not correspond to the ACK signal, the controller 100 proceeds to step 500 to apply power to the touch sensor 120a according to a preset synchronization pattern. So that the noise of the pattern corresponding to the conductor 200 can be conducted through the conductor 200.

If it is determined in step 514 that the noise sensed by the conductor 200 corresponds to the predetermined ACK signal, the controller of the first terminal 100a synchronizes with the second terminal 100b And transmits the data. That is, the controller of the first terminal 100a switches the operation mode back to the operation mode for transmitting data, and applies power to the touch sensor 120a according to the pattern corresponding to the data to be transmitted (S516). In this case, the noise corresponding to the data to be transmitted may be conducted along the conductor 200 contacting the touch sensor 120a (518).

On the other hand, when the noise of the pattern corresponding to the ACK signal is transmitted through the conductor 200, the control unit of the second terminal 100b can switch the operation mode to the operation mode for receiving the data again. The control unit of the second terminal 100b may sense the noise transmitted through the conductor 200. If there is no noise sensed by the conductor 200 or a noise corresponding to the synchronization pattern is sensed by the conductor 200 so that the predetermined time elapses, the control unit of the second terminal 100b returns to step 508 It is also possible to switch the operation mode to the data transmission mode and apply power to the touch sensor 120b in a pattern corresponding to the predetermined ACK signal. This is for transmitting an ACK signal to the second terminal 100b once again.

Meanwhile, when the noise is detected in the conductor 200, the controller of the second terminal 100b may code the sensed noise to generate data (520). Accordingly, the same data as the data transmitted from the first terminal 100a can be generated in the second terminal 100b, so that data can be transmitted from the first terminal 100a to the second terminal 100b.

On the other hand, in the above description, it has been mentioned that an operation mode for transferring data can be determined according to the user's selection. FIG. 6 shows an example of a screen in which an operation mode is set according to a user's selection in the mobile terminal related to the present invention.

For example, when the mobile terminal 100 according to the present invention is in a sleep state, when the user's touch is detected, the mobile terminal 100 displays image information including a graphic object for selecting an operation mode from the user And can be displayed on the display unit 140. In this case, the controller 110 may operate in a specific operation mode according to a user's selection.

For example, as shown in FIG. 6 (a), if the user's touch is detected when the mobile terminal is in the sleep state, the control unit 110 of the mobile terminal 100 according to the embodiment of the present invention, It is possible to switch the operation state of the mobile terminal 100 from the user to the wake up state or to perform data communication with other mobile terminals according to the embodiment of the present invention through the image information 600 displayed on the display unit 140 It is possible to select the switching to the operation mode.

6 (b), when the user selects the data communication according to the embodiment of the present invention, the control unit 110 selects a mode for transmitting data or a mode for receiving data according to a user's selection . ≪ / RTI > In this case, if the user selects an operation mode for transmitting data, the control unit 110 displays a screen for allowing the user to select data to be transmitted, as shown in FIG. 6C, on the display unit 140 ). ≪ / RTI >

When the user selects data to be transmitted, the controller 110 generates a power supply pattern corresponding to the binary code of the data to be transmitted, and can apply power to the touch sensor 120 accordingly. In this case, the control unit 110 may display a graphic object 604 on the display unit 140 to inform that the current data is being transmitted.

Meanwhile, as shown in FIG. 6 (d), a conductor in contact with the touch sensor 120 may be conducted to a mobile terminal with a noise corresponding to the power application pattern along the user's finger. The other mobile terminal generates data based on the transmitted noise, so that the data selected in (c) of FIG. 6 can be transmitted to another mobile terminal.

2A and 2B, data is transmitted between two mobile terminals. However, it is needless to say that data may be transmitted to a plurality of other terminals.

FIG. 7 illustrates an example in which data is transmitted between a plurality of mobile terminals according to an embodiment of the present invention.

Referring to FIG. 7, FIG. 7 shows an example in which a plurality of receiving terminals 710, 720 and 730 are connected to a transmitting terminal 700 through a conductor 750. The first surface of the conductor 750 is in contact with the touch sensor of the transmitting terminal 700 and the second, third and fourth surfaces 754, 756 and 758 of the conductor 750 are respectively connected to And is in contact with the touch sensors of the terminals 710, 720, 730.

When a plurality of terminals 710, 720 and 730 are connected through the conductor 750, the data transmitted from the transmitting terminal 700 can be simultaneously transmitted to the plurality of terminals 710, 720 and 730 have. According to an embodiment of the present invention, when power is applied to the touch sensor of the transmitting terminal 700 in a pattern corresponding to the data to be transmitted, the noise generated due to the contact of the first surface 752, Third, and fourth sides 754, 756, and 758 of conductor 750 along line 750, respectively.

Not only can the same data be simultaneously transmitted to the plurality of receiving terminals 710, 720 and 730, but also different data can be transmitted to the plurality of receiving terminals 710, 720 and 730, respectively to be.

For example, when the transmitting terminal 700 performs a pairing with each of the plurality of terminals 710, 720, and 730 for data transmission, the transmitting terminal 700 may be synchronized differently. That is, the transmitting terminal 700 may synchronize with the plurality of terminals 710, 720, and 730 at different time intervals to transmit different data to each of the plurality of terminals 710, 720, and 730 .

Alternatively, the transmitting terminal 700 may synchronize data of different patterns with the plurality of terminals 710, 720, and 730, respectively. That is, the transmitting terminal 700 sets different start codes for notifying the start of transmission of data and an end code for notifying the transmission of data to the plurality of terminals 710, 720, and 730, It is possible to generate a power-on pattern included in the data to be transmitted.

In this case, the receiving terminals 710, 720, and 730 may sense the noise transmitted from the conductor 750 and determine whether the code formed by the noise is a predetermined start code. If noise corresponding to the predetermined start code is sensed, the noise detected from one side of the current touch conductor 750 identifies the data related to the data to be transmitted to the touch conductor 750, And generate data corresponding to the detected noise.

Accordingly, in the present invention, data can be transmitted not only to one terminal but also to a plurality of mobile terminals. Here, the same data may be simultaneously transmitted to the plurality of terminals, or different data may be transmitted to each of the plurality of terminals as described above.

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). Also, the computer may include a control unit 180 of the terminal. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
