Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Terminal interworking and control system of the present invention relates to a system for interlocking and controlling the terminals, in particular a system for controlling the operation of the terminal based on the image sharing and the shared image. In particular, the terminal interworking and control system of the present invention, after interlocking a small size terminal directly controlled by the user, for example, a touch method and a large size terminal, while the user looks at the large size terminal of the small size Various methods for controlling the terminal are proposed. However, for convenience of description, a small sized terminal directly controlled by a user is called a user terminal, and a large sized terminal that receives location information of the touch means from the user terminal is called a receiving terminal. Of course, the user terminal preferably has a smaller size than the receiving terminal, but the size of the terminals is not limited to the above size.

The terminal used in the system of the present invention has a function of displaying an image and a wired / wireless communication function, but the communication function is not an essential function. However, considering the real life application, it is preferable that each terminal has an image display function and a communication function. The terminal is not limited to a specific device as long as it can display an image and transmit or receive a signal with another terminal, for example, a smartphone, a smart TV, a PC, a tablet PC, a laptop, a touch pad, a game console, a cloud PC, or the like. Various devices can be used as the terminal of the present invention. However, it is preferable that a terminal having a small size has a touch function.

Hereinafter, a terminal interworking and control system according to various embodiments of the present invention will be described with reference to the accompanying drawings. However, for convenience of description, an image shared by the terminals will be referred to as a first image, and an image representing position information of the touch means will be referred to as a second image (location display image).

1 is a view schematically showing a terminal interworking and control system according to an embodiment of the present invention.

Referring to FIG. 1, the terminal interworking and control system of the present embodiment includes a user terminal 100 and a receiving terminal 102.

The user terminal 100 may be an image display terminal directly controlled by the user, and may be, for example, a smartphone capable of executing a game such as Angry Birds. Preferably, the user terminal 100 is a terminal having a touch function and having a relatively small size.

The receiving terminal 102 is a terminal which is not directly manipulated by a user but interlocks with the user terminal 100 and which can display an image. The reception terminal 102 may be an element used for a different purpose than the user terminal 100, and may be, for example, a TV that broadcasts a broadcast program such as a drama. Preferably, the receiving terminal 102 is a terminal having a relatively large size, but does not necessarily have a touch function.

The terminals 100 and 102 may be connected directly or indirectly by wire or wirelessly using another device, and are connected through a plurality of channels, for example, two channels. One channel is used to transmit image data (image information) corresponding to the shared first image, and the other channel is used to transmit a control signal having position information of the touch means. The channels may all be wireless channels or wired channels, one may be a wireless channel and the other may be a wired channel. Of course, the terminals 100 and 102 may transmit and receive image data and control signals through one channel. For example, the transmission interval of the channel may include a control interval for transmitting a control signal between data intervals for transmitting image data. In particular, since a blank period exists between sections for transmitting image data, the blank period may be used as a control signal transmission section. For example, the user terminal 100 transmits image data to the receiving terminal 102 through one channel, but receives a control signal during a blank period between data sections for transmitting the image data. Can be sent to. However, when real-time interworking of the terminals 100 and 102 is important, it is preferable that a data channel for transmitting image data and a control channel for transmitting a control signal exist separately.

The user terminal 100 transmits the data corresponding to the first image to be displayed or displayed by the user to the receiving terminal 102 through the corresponding channel under the control of the user, and transmits the data to the receiving terminal 102 through the corresponding channel. The control signal may be separately transmitted to the receiving terminal 102 through the corresponding channel. Currently, terminals such as smartphones and TVs use wired communication standards such as high-definition multimedia interface (HDMI), mobile high definition link (MHL), displayport, and wireless communication standards such as WiFi, and they each transmit data. It is equipped with a separate control channel for transmitting and receiving control signals as well as a data channel. For example, HDMI uses CEC (Consumer Electronic Control), DDC (Display Data Channel), Utility, SCL / SDA as control channels, MHL uses CBUS as control channels, and Displayport controls auxiliary channels. I am using it as a channel. Therefore, it is not necessary to set up separate channels in order to interwork with the terminals 100 and 102, and channels already existing in the terminals 100 and 102 may be used as channels for transmitting the control signal of the present invention.

Although not mentioned above, the receiving terminal 102 may also transmit an image signal or the like to the user terminal 100. In this case, the receiving terminal 102 may use channels other than the above data channel / control channel, but it is preferable to use the same data channel / control channel.

When the user terminal 100 distributes the image data corresponding to the first image displayed by the user terminal to the image signal and transmits the image data to the receiving terminal 102 through the corresponding channel, the receiving terminal 102 transmits the image data through the image signal. Acquire and display a first image corresponding to the image data. As a result, the user terminal 100 and the receiving terminal 102 display the same first image, that is, share the first image. However, the first image displayed on the receiving terminal 102 is substantially the same as the first image displayed on the user terminal 100, but due to the characteristics of the terminal of the receiving terminal 102, the color is different or the display ratio is different. There is a number. Although the receiving terminal 102 may display the transmitted image data as a corresponding image without special processing, the receiving terminal 102 may display the first image by processing the transmitted image data according to its characteristics. That is, as long as the receiving terminal 102 can display an image substantially the same as the first image of the user terminal 100, the method of processing the transmitted image data may be variously modified.

When the same image as the first image of the user terminal 100 is displayed on the receiving terminal 102, the receiving terminal 102 may stop the existing executing program and display the first image or execute the existing executing program. It can also be run through a separate channel. In addition, the receiving terminal 102 may display the existing execution program together on the screen on which the first image is displayed. For example, the receiving terminal 102 may stop the drama, which is an existing execution program, and display the first image of the Angry Bird game that is executed in the user terminal 100, for example, by switching the drama to a separate channel. The first image may be broadcasted and the first image may be displayed on a corresponding channel, or the drama may be continuously broadcasted on the current channel, but the first image may be displayed on another channel. In addition, the receiving terminal 102 may display the first image on the current channel, but display the drama that was being aired in a separate pop-up window. However, since the present invention is intended for a user to view the first image of the user terminal 100 through the receiving terminal 102, the receiving terminal 102 stops a program executed in the current channel or displays the display through another channel. It is preferable to switch the screen of the current channel to the screen on which the first image is displayed.

According to another embodiment of the present invention, the receiving terminal 102 may share the first image by transmitting an image signal to the user terminal 100. Even in this case, the control signal reflecting the user's operation (touch operation) is transmitted from the user terminal 100 to the receiving terminal 102.

Image sharing between the user terminal 100 and the receiving terminal 102 is not performed only once, but the same image is displayed to the receiving terminal 102 whenever the first image of the user terminal 100 is switched. Therefore, when the user operates the user terminal 100, the first image corresponding to the operation is displayed on the receiving terminal 102. In particular, since the receiving terminal 102 has a relatively larger size than the user terminal 100, the user may control the user terminal 100, but the gaze may look at the receiving terminal 102. That is, the user may manipulate the user terminal 100 while looking at the receiving terminal 102.

However, if the user terminal 100 is not viewed, it is difficult to grasp its own operation, and if the receiver terminal 102 is not present, the screen is small, so that the present invention can easily control the user terminal 100 while watching the receiver terminal 102. Various methods and systems are proposed.

According to an embodiment of the present invention, when a touch means such as a user's finger is close to a touch sensing area of the user terminal 100, for example, a screen, the touch means may be displayed on the first image displayed on the receiving terminal 102. A corresponding second image, for example a shadow image, may be displayed at that location, ie the position of the touch means is specified above the first image. In the case of a general PC, not an interlocking system, if the mouse is moved, the position of the mouse is not specified to the exact position, and in the case of a smartphone, the image indicating the position is not displayed even if it is touched. On the other hand, the present invention specifies the position of the touch means on the user terminal 100 to the receiving terminal 102 as a shadow image, while interlocking the user terminal 100 and the receiving terminal 102. Therefore, the user can check the position and the operation touched by the user while not looking at the user terminal 100 but can control the receiver terminal 102 without looking at the receiver terminal 102. Subsequently, when the user touches and moves the screen of the user terminal 100, the position of the second image may change according to the movement. In this case, the second image may be maintained as a shadow image, or the finger image may move on the first image according to the movement after the shadow image as the second image is changed to a finger image. Therefore, the user can check the operation status of the touch means in the user terminal 100 through the receiving terminal 102, and as a result, the user does not look at the user terminal 100, but only while looking at the receiving terminal 102. 100 can be easily controlled. For example, when a user is playing an Angry Birds game with a smartphone, the user may enjoy the Angry Birds game by operating the smartphone while watching only a TV screen having a large size. If the first image displayed on the user terminal 100 is changed to another first image according to a user's operation, the same first image is displayed on the receiving terminal 102, in which case the second image is displayed on the new first image. It is displayed at that location. The second image may be displayed on the screen of the receiving terminal 102 based on the coordinates of the user terminal 100. Of course, the first image may be shared according to image data transmission of the user terminal 100 or may be shared according to image data transmission of the receiving terminal 102.

According to another exemplary embodiment of the present invention, when the user approaches the touch sensing unit from the user terminal 100 having a touch sensing unit, for example, a touch pad, separately from the display unit, such as a laptop, the sensing unit 102 detects this. The second image may be displayed on the first image. That is, as long as the user terminal 100 can detect the touch means, the area for detecting the touch means is not limited to a specific portion of the user terminal 100.

In summary, the user terminal 100 and the receiving terminal 102 share the first image, and the user can easily manipulate the user terminal 100 having the small size while viewing the receiving terminal 102 having the large size. have. Accordingly, the user may move the touch means such as a finger or a touch pen on the image of the user terminal 100 while looking at the receiving terminal 102 or click a menu icon displayed on the first image of the user terminal 100 to specify You can also run the function. Of course, according to the above execution, an image substantially identical to the new first image displayed on the user terminal 100 is displayed on the receiving terminal 102.

Although not described above, once the second image is specified on the receiving terminal 102, the second image may reflect the movement of the touch means, but the second image may be moved by manipulating a physical keyboard, a keyboard displayed on the screen, and the like. It may be.

According to another embodiment of the present invention, the companion system may include a plurality of user terminals 100 and one receiving terminal 102. For example, when a plurality of users are playing the same game, the user terminals 100 are wired or wirelessly connected to the receiving terminal 102. When the user terminals 100 respectively transmit the position information of the corresponding touch means to the receiving terminal 102, the receiving terminal 102 displays second images indicating the positions of the touch means on the same first image. Can be. In this case, the first image shared by the user terminals 100 and the receiving terminal 102 may be transmitted by the specific user terminal 100 to the receiving terminal 102.

According to another embodiment of the present invention, when a plurality of touch means touches one user terminal 100, for example, a user touches the user terminal 100 with one left and right fingers or a plurality of users When the user terminal 100 is touched, the user terminal 100 transmits a control signal including the location information of the touch means to the receiving terminal 102, and the receiving terminal 102 according to the control signal has a first image. Second images corresponding to the location information may be displayed. Of course, shapes, colors or sizes may be different so that the second images are distinguished from each other. Meanwhile, the user terminal 100 may transmit a plurality of control signals having location information of each touch means to the receiving terminal 102.

According to another embodiment of the present invention, the user terminal 100 may sense the touch means by another method by realizing a plurality of sensing methods. For example, the user terminal 100 may sense a finger through a capacitive method and a touch pen using a receiver. Therefore, the user may implement multi-touch by simultaneously using a finger and a touch pen. As a result, the user can realize a separate operation by using a plurality of touch means.

According to another embodiment of the present invention, the companion system may include a user terminal, a receiver terminal, and a companion server. The companion server transmits the first image to both the user terminal and the receiving terminal to display the same first image, and the user terminal transmits the position information of the touch means to the receiving terminal to display the second image on the first image. May be displayed.

Hereinafter, various embodiments of the terminal interworking and control method of the present invention will be described with reference to the accompanying drawings.

2 is a flowchart illustrating a terminal interworking and control method according to a first embodiment of the present invention, FIG. 3 is a diagram illustrating a control method used in the terminal interworking and control method of FIG. 2, and FIG. FIG. 1 is a plan view illustrating an image sharing screen according to an exemplary embodiment. This embodiment proposes a linkage and control method when the user terminal 100 transmits image data (image signal) to the reception terminal 102.

Referring to FIG. 2, the user terminal 100 requests the linkage of an image to the receiving terminal 102 (S200). Specifically, when the user connects the user terminal 100 to the receiving terminal 102 by wire or wirelessly and requests interlocking, or when the user terminal 100 is connected to the receiving terminal 102, the user terminal 100 or the receiving terminal 102. After the terminal 102 identifies the counterpart terminal, the terminal 102 may inquire whether to interwork with the counterpart terminal. Interworking of the terminals 100 and 102 may be performed at the request of a user, or may be automatically performed when the terminals 100 and 102 mutually identify each other. According to an embodiment of the present invention, as shown in FIG. 3A, the user terminal 100 and the receiving terminal 102 may be connected to two channels, that is, a data channel and a control channel, and may request an interworking request or Control signals for permission can be transmitted and received through the control channel.

Subsequently, the user terminal 100 distributes image data corresponding to the first image displayed on the screen to an image signal and transmits the image data to the receiving terminal 102 through the data channel, and the receiving terminal 102 transmits the transmitted image. The first image corresponding to the data is displayed (S202). That is, the user terminal 100 and the receiving terminal 102 share the first image. Since it is useful to display the first image of the user terminal 100 and the first image of the receiving terminal 102 at substantially the same time, the image portion of the user terminal 100 transmits the image data to the display unit when the image data is transmitted. It is desirable to transmit simultaneously to the receiving terminal 102 through the channel.

Subsequently, when a user approaches a touch means such as a finger or a touch pen to the user terminal 100, the user terminal 100 detects the touch means (S204). Specifically, the user terminal 100 detects the touch means when the touch means enters a detectable area. For example, the user terminal 100 may use a capacitive touch panel, and when the user approaches the finger to the user terminal 100, the user terminal 100 may detect the capacitance change caused by the finger to detect the position of the finger. have. However, for this sensing, the user terminal 100 may set the sensing level to a plurality of levels, for example, two levels, as shown in FIG. 3B. When not performing the terminal interworking process, that is, when the user uses only the user terminal 100, the detection level of the user terminal 100 is set to a high level (L2) so that the touch position is detected only when the user touches. . On the other hand, when the user performs the terminal interworking process, that is, also using the receiving terminal 102, the user terminal 100 changes the detection level to a low level (L1). Therefore, the user terminal 100 may detect the touch means even when the touch means is not in touch but in close proximity. That is, the user terminal 100 may set different sensing levels depending on whether or not the terminal interworking process is used. According to another embodiment of the present invention, the user terminal 100 may use a variety of methods, such as electromagnetic induction, resistive film, optical, ultrasonic method, in addition to the capacitive method, the setting conditions may vary depending on the usage method .

Subsequently, the user terminal 100 transmits a control signal including position information of the touch means according to the detection result to the receiving terminal 102 through a control channel, and the receiving terminal 102 transmits the control signal according to the control signal. A second image according to the location information, for example, a shadow image 400 as shown in FIG. 4 is displayed on the first image (S206). In the above, signals are transmitted differently by being divided into a data channel and a control channel, but both image data and a control signal may be transmitted through the data channel. For example, the user terminal 100 sets the control section 112 between the data sections 110 and 114 as shown in FIG. 3C to control the signal C1 during the control section 112. Can transmit

Subsequently, when the user touches and moves the user terminal 100 by using a touch means, the user terminal 100 generates a control signal including the position information according to the movement and transmits it to the receiving terminal 102, and the receiving terminal 102. 102 displays the second image on the first image according to the transmitted control signal (S208). As a result, the second image is displayed on the first image of the receiving terminal 102 to reflect the movement of the touch means. Of course, when the user clicks a menu for performing a specific operation on the first image on the user terminal 100, only image switching is performed, and thus, the receiving terminal 102 maintains the second image at the current position. Only an image may be changed into a new image of the user terminal 100.

In summary, the terminal interworking and control method of the present invention detects the proximity of the touch means in the state where the first image is shared, displays a second image on the first image of the receiving terminal 102, and the user selects the user terminal ( When touching or moving after the touch, the second image reflecting the movement is displayed on the first image of the receiving terminal 102.

The first image and the second image displayed on the receiving terminal 102 may overlap as separate images, or a composite image generated by combining the first image and the second image may be displayed.

Although the second image is referred to as being displayed on the first image, the display method may be variously modified as long as the second image is displayed together with the first image. For example, a portion of the first image corresponding to the position of the touch unit may be darkly expressed, and the darkly expressed portion may be the second image.

Hereinafter, various methods of sensing the touch means will be described with reference to the accompanying drawings.

As a basic method of detecting the touch means, the display unit of the user terminal 100 is configured by a capacitive touch panel, and a touch means such as a finger, or the like, is used. In this case, the sensing unit of the user terminal 100 detects the position of the touch means by changing the capacitance when approaching and touching the touch means.

There are other methods of sensing the touch means, which will be described with reference to FIGS. 5 to 7 below.

5 is a diagram illustrating a touch means sensing method according to an embodiment of the present invention.

Referring to FIG. 5, the touch pen 500 may be used as a touch means for touching the user terminal 100. The user terminal 100 uses a capacitive touch panel.

The touch pen 500 includes a body 510 and a touch unit 512. Body 510 is made of a material that does not conduct electricity, the touch unit 512 is a conductor. Therefore, due to the touch unit 512, a change in capacitance occurs when the touch pen 500 approaches the user terminal 100 or when the user touches the user terminal 100. As a result, the user terminal 100 touches. The pen 500 may be sensed. That is, unlike the general touch pen that could not be used in the capacitive method, the touch pen 500 of the present invention can be used in the capacitive method. Of course, the entire touch pen 500 may be made of a conductor. However, in consideration of cost, it is preferable to manufacture only the touch unit 512 that is actually touched with a conductor.

6 is a view showing a touch means detection method according to another embodiment of the present invention.

Referring to FIG. 6A, a receiver 600 may be mounted on a part of the user terminal 100, and a touch pen 602 may be used.

The receiver 600 may include one infrared sensor and two ultrasonic sensors. The receiver 600 may detect the movement of the touch pen 602 by receiving infrared rays and ultrasonic waves transmitted from the touch unit (tip) of the touch pen 602. The control signal having the position information of the touch pen 602 according to the detection result is transmitted to the receiving terminal 102. The receiving terminal 102 analyzes the control signal to detect the position of the touch pen 602 and displays a second image at the detected position. As a result, the second image is displayed together with the first image. In this case, the control signal may be transmitted by the receiver 600 to the receiving terminal 102 or the user terminal 100 may be transmitted to the receiving terminal 102.

Looking at how the receiver 600 detects the position of the touch pen 602, three sensors respectively measure the transmission time of the infrared ray and the transmission time of the ultrasonic wave, converts the transmission times into distances, and converts the converted distances. The position of the touch pen 602 is detected through a method similar to triangulation. Therefore, even if the touch pen 602 is close without directly touching the user terminal 100, the position of the touch pen 602 may be sensed, and the touch and movement of the touch pen 602 may be accurately sensed. Of course, signals other than infrared and ultrasonic may also be used.

The second image reflecting the position of the touch pen 602 may not be displayed on the user terminal 100 but only on the receiving terminal 102. Of course, the user terminal 100 operates in response to the movement of the touch pen 602.

According to another embodiment of the present invention, the receiver 600 not only detects the position of the touch pen 602 but also transmits an image signal and a control signal including image data to the receiving terminal 102. Can be. In detail, the receiver 600 may include a touch controller 610, an image signal unit 612, a control signal unit 614, and a transceiver unit 616. The touch controller 610 detects the position of the touch pen 602 by using the received infrared rays and ultrasonic waves, and provides information about the detected position to the user terminal 100. The user terminal 100 displays the location of the touch pen 602 or performs a related operation according to the provided information. The image signal unit 612 receives image data from the user terminal 100, and transmits the provided image data to the receiving terminal 102 through the transceiver 616. The control signal unit 614 transmits a control signal having the detected position information of the touch pen 602 to the receiving terminal 102. That is, since the receiver 600 transmits a control signal having the image data transmitted from the user terminal 100 and the position information of the touch pen 602 to the receiving terminal 102, the user terminal 100 does not have a communication function. Not enough.

7 is a diagram illustrating a touch means sensing method according to another embodiment of the present invention.

Referring to FIG. 7, the user terminal 100 includes a touch panel 700 and an electromagnetic generator 702.

The electromagnetic generator 702 may be connected to the rear surface of the touch panel 700, and may be formed of a thin metal film to generate an electromagnetic field when electricity flows.

The touch pen 707 includes a body 710 and a touch unit 712, and the touch unit 712 may be preferably made of a small metal coil. As a result, when the touch pen 704 is close to the touch panel 700, an electromagnetic induction phenomenon occurs in the touch unit 712, and as a result, a deformation of the electromagnetic field generated from the electromagnetic generator 702 occurs. Therefore, the user terminal 100 detects the deformation of the electromagnetic field and recognizes the position of the touch pen 704. In particular, since the deformation of the electromagnetic field varies depending on the approach position and the touch intensity of the touch pen 704, the touch means sensing method detects the touch pen 700 and the touch pressure of the touch pen 700 in detail. can do. Therefore, the size of the second image displayed on the receiving terminal 102, the thickness of the line when represented by a line, and the like may be displayed differently according to the position or pressure of the touch pen 704. Of course, the shape, size or color of the second image may vary depending on the touch intensity.

5 to 7, the user terminal 100 may detect the touch pen through various methods and reflect the detection result to the receiving terminal 102.

As described above, the user terminal 100 detects the touch means close to the detectable area and transmits the location information of the touch means to the receiving terminal 102, where the detectable area is a predetermined distance from the user terminal 100. It may be spaced apart. That is, the user terminal 100 may detect a touch means close to the user terminal 100 located within a predetermined distance from the user terminal 100. The preset distance may vary depending on the sensing scheme described above. For example, when the capacitive touch panel is used in the user terminal 100, the preset distance may be a distance corresponding to the low level L1 described with reference to FIG. 3. In addition, the preset distance may be set based on the shortest distance between the touch means and the user terminal 100.

8 is a flowchart illustrating a terminal interworking and control method according to a second embodiment of the present invention.

That is, the user terminal 100 and the receiving terminal 102 share the first image.

Subsequently, the user terminal 100 detects a touch means such as a finger or a touch pen through various methods (S804).

Subsequently, the user terminal 100 generates a composite image displaying a second image corresponding to the position of the sensed touch means together with the currently displayed first image, and generates composite image data (synthesis information) corresponding to the composite image. ) Is transmitted to the receiving terminal 102, and the receiving terminal 102 displays the composite image corresponding to the composite image data (S806). As a result, the fisheries terminal 102 displays a screen on which the second image is displayed together with the first image. In this case, only the first image may be displayed on the user terminal 100, or a screen on which the second image is displayed together with the first image may be displayed.

Subsequently, when the user touches or moves in the touched state, the user terminal 100 transmits a control signal having the position information of the touch means to the receiving terminal 102, and the receiving terminal 102 transmits the touch signal. According to a control signal, a second image indicating the position of the touch means is displayed together with the corresponding first image (S808). That is, the movement of the touch means is reflected on the screen of the receiving terminal 102. However, the first image on the receiving terminal 102 may be the same image as the previous image or may be different from the previous image.

In summary, unlike the first embodiment in which the receiving terminal 102 generates the second image and displays the second image together, in the present embodiment, the user terminal 100 synthesizes the first image and the second image. A composite image is generated and the generated composite image is transmitted to the receiving terminal 102. As a result, the receiving terminal 102 displays a screen on which the second image is displayed together with the first image.

Specifically, a first level for detecting the touch means when the touch means is close to the user terminal 100 and a second level for detecting the touch means when the touch means touches are set. Of course, the levels for sensing the touch means may be set more precisely.

Subsequently, the user terminal 100 detects the touch means and displays a second image on the receiving terminal 102 indicating the position of the touch means (S904).

Subsequently, it is determined whether or not there is a request for interlocking stop by the user (S906). The interworking stop may be requested by the user by selecting a menu or by turning off the connection between the user terminal 100 and the receiving terminal 102. When the user controls the user terminal 100 while viewing the receiving terminal 102 and wants to use only the user terminal 100 or only wants to view the receiving terminal 102, the user terminal 100 and the receiving terminal 102 You can request to stop interlocking while connected.

If there is no user stop request for interworking, step S904 is performed again.

On the other hand, when the user stops the interlocking request of the user, the user terminal 100 initializes the plurality of levels to change to the sensing levels to detect only one level is present or touched (S908). That is, when the touch means is not touched, the user terminal 100 does not sense the touch means but changes the level so as to detect the touch means only when the touch means is touched.

In summary, in the terminal interworking and control method of the present invention, a user may freely set and change an interworking request, an interlocking stop request, and a sensing level.

According to another embodiment of the present invention, the first detection level may be set when the user terminal 100 and the reception terminal 102 start interlocking, and the detection level may be differently set during the interlocking. For example, the user may set different sensing levels according to the approach distance and the touch intensity of the touch means during interlocking, or change the sensing level setting to sense only when the touch means is touched.
