Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object existing nearby using the force of an electromagnetic field or infrared rays without mechanical contact. In the proximity sensor 141, the proximity sensor 141 may be disposed in an inner area of the mobile terminal surrounded by the touch screen as described above or near the touch screen. The proximity sensor 141 has a longer lifespan and higher utilization than a contact sensor.

When the touch screen is a capacitive type, the proximity sensor 141 may be configured to detect the proximity of the object by a change in the electric field according to the proximity of the conductive object. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the action of allowing an object to be recognized as being positioned on the touch screen by being approached without contacting an object on the touch screen is called "proximity touch", and the touch The act of actually touching an object on the screen is referred to as "contact touch". A position at which an object is touched in proximity on the touch screen means a position at which the object is vertically corresponding to the touch screen when the object is touched in proximity. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (eg, proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, etc.). have. Meanwhile, as above, the controller 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141, and further, provides visual information corresponding to the processed data.

The touch sensor may be configured to detect a location, area, and pressure at the time of a touch on the touch sensor by a touch object applying a touch on the touch screen. Here, the touch object is an object that applies a touch to the touch sensor, and may be, for example, a finger, a touch pen, a stylus pen, or a pointer.

In this way, when there is a touch input to the touch sensor, the signal(s) corresponding thereto is transmitted to the touch controller. The touch controller processes the signal(s) and then transmits the corresponding data to the controller 180. As a result, the controller 180 can know whether an area of the display unit 151 is touched. Here, the touch controller may be a separate component from the controller 180 or may be the controller 180 itself.

Meanwhile, the controller 180 may perform different controls or perform the same control according to the type of the touch object by touching the touch screen (or a touch key provided in addition to 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 an operating state of the mobile terminal 100 or an application program being executed.

The ultrasonic sensor may recognize location information of a sensing target by using ultrasonic waves. Meanwhile, the controller 180 may calculate the location of the wave generator through information sensed from the optical sensor and the plurality of ultrasonic sensors. The location of the wave generator may be calculated by using a property that the light is much faster than the ultrasonic wave, that is, the time that the light reaches the optical sensor is much faster than the time that the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generator may be calculated using a time difference between a time when the ultrasonic wave arrives using light as a reference signal.

Meanwhile, the camera 121 is a type of camera sensor, viewed as the configuration of the input unit 120, and the camera sensor includes at least one of a camera 121, a photo sensor, and a laser sensor.

The photosensor may be stacked on the display device, and the photosensor is configured to scan a motion of a sensing object close to the touch screen. More specifically, the photo sensor scans the contents placed on the photo sensor by mounting a photo diode and a transistor (TR) in a row/column and using an electrical signal that changes according to the amount of light applied to the photo diode. That is, the photosensor calculates the coordinates of the sensing target according to the amount of light change, and through this, the location information of the sensing target may be obtained.

4 is a flowchart illustrating an operation of a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 4, the controller 180 may detect a change in the magnetic field as the mobile terminal 100 approaches at least one external device through the sensing unit 140 (401).

Also, when a change in the magnetic field is detected, the controller 180 may control the wireless communication unit 110 to attempt to establish a wireless channel with the at least one external device (403).

Here, the wireless channel refers to a channel for performing communication in any one of various communication methods capable of communicating with at least one external device through the wireless communication unit 110. For example, in the wireless channel, the mobile terminal 100 communicates with external devices such as Bluetooth™, RFID (Radio Frequency Identification), infrared communication (Infrared Data Association; IrDA), UWB (Ultra Wideband), ZigBee, NFC ( Near Field Communication), Wi-Fi (Wireless-Fidelity), and Wi-Fi Direct technology may be a channel for performing communication in at least one method.

The attempt to establish the radio channel will be described later in the description of FIG. 5B.

FIG. 5 is a conceptual diagram illustrating a method of establishing a communication channel with an external device by a mobile terminal according to an embodiment of the present invention, and FIG. 6 is a diagram illustrating a change in a magnetic field detected by a mobile terminal according to an embodiment of the present invention. It is an exemplary diagram for.

Referring to FIG. 5A, the controller 180 may sense a change in a magnetic field as the mobile terminal 100 approaches the external device 500 through the sensing unit 140. That is, since the external device 500 is an electronic device capable of wireless communication, it generates a magnetic field around the external device. In addition, since the mobile terminal 100 is also an electronic device, a magnetic field is generated around the mobile terminal 100. When the mobile terminal 100 approaches the external device 500 as shown in FIG. 5A, the magnetic field generated by the mobile terminal 100 is disturbed by the magnetic field generated by the external device 500.

In this case, the sensing unit 140 may include a geomagnetic sensor capable of detecting a change in a magnetic field of three axes. The geomagnetic sensor can detect a magnetic field in the direction of three axes (x, y, and z) around the mobile terminal 100, and the controller 180 is configured to disturb at least one of the three magnetic fields through the geomagnetic sensor. If so, it is possible to detect changes in magnetic field.

6 is a graph for explaining a change in a magnetic field sensed through an earth value sensor. For convenience of explanation, it is assumed that the magnetic fields 610, 620, and 630 in the three-axis directions are the x-axis 610, the y-axis 620, and the z-axis 630. In addition, reference lines 601 and 602 for schematically representing the change in the magnetic field are shown. In particular, the reference line 602 refers to the time axis t, and when t=0, it is assumed that the geomagnetic sensor of the sensing unit 140 does not detect the magnetic field disturbance by the external device 500.

Thereafter, the x-axis magnetic field 610, the y-axis magnetic field 620, and the z-axis magnetic field 630 represent changes in respective magnetic fields when the mobile terminal 100 approaches the external device 500 over time. . The circle 600 is for explaining the amount of change in the 3-axis magnetic field in a specific time period, and is not related to the actual waveform. On the other hand, it can be seen that the magnetic field is disturbed and converges after a certain period of time has elapsed. The controller 180 may determine the magnetic field disturbance by sensing a specific value of the magnetic field through the geomagnetic sensor, but may determine the magnetic field disturbance by sensing a change in the magnetic field. Hereinafter, a case in which the controller 180 determines magnetic field disturbance according to a change in the magnetic field will be described as an example.

As time elapses, the mobile terminal 100 approaches the external device 500, and among the magnetic fields around the mobile terminal 100, the x-axis 610 gradually decreases from a predetermined size to converge, and then a specific value again. A case in which the waveform increases to and then converges to a constant value is illustrated as an example. In addition, the y-axis 620 and the z-axis 630 have a waveform that increases to a specific value as the mobile terminal 100 approaches the external device 500 at a predetermined size and then converges. .

The change in the magnetic field of the three axes is only an example, and the controller 180 does not detect that the magnetic field is disturbed only when the x-axis magnetic field, y-axis magnetic field, and z-axis magnetic field have the waveforms shown in FIG. 6.

While the magnetic field shows the waveform change as shown in FIG. 6, the x-axis magnetic field 610, y-axis magnetic field 620, and z-axis magnetic field 630 having different values in the circle 600 converge to a specific value, respectively. It can be seen that the waveform changes in the form of scattering. The controller 180 may detect a change in a waveform that converges and then scatters in the circle 600 through a geomagnetic sensor, that is, a change in a magnetic field. In this case, the controller 180 may control the wireless communication unit 110 to attempt to establish a wireless channel.

6 illustrates a case where all three-axis magnetic fields 610, 620, and 630 are scattered, the controller 180 detects a change in the magnetic field even when only at least one magnetic field is disturbed, and the wireless communication unit 110 It can be controlled to attempt to establish a wireless channel.

Referring to FIG. 5B, as a magnetic field change is detected, an external device is scanned through the wireless communication unit 110, and when at least one external device 500 is scanned, the controller 180 is The setting screen 503 for establishing a wireless channel may be controlled to be displayed through 151. Here, the setting screen 503 means a screen including information related to a wireless channel establishment process, such as a target for attempting to establish a radio channel, a progress of establishing a radio channel, and a communication method used for establishing a radio channel. That is, it is a screen for notifying the user of information related to establishing a wireless channel.

In addition, the controller 180 may control to display a list of external devices 500 attempting to establish a wireless channel on the setting screen 503. The controller 180 may control to display identification information 505 on the external device 500 to be attempted to establish a wireless channel on the list. The identification information 505 may include at least one of information through which the controller 180 can identify the external device 500, such as a name, serial number, and MAC address of the external device 500.

In addition, the controller 180 detects the type of the scanned external device 500 as a result of scanning for establishing a wireless channel, and controls an icon indicating the type of the external device 500 to be displayed on the list. have. The external device to which the mobile terminal 100 is adjacent in FIG. 5A is an audio device 500, and an audio icon indicating the stanched external device 500 in FIG. 5B is illustrated as an example. .

In addition, when the establishment of the wireless channel with the external device 500 is completed, the controller 180 may control a wireless channel establishment notification message to be displayed on the list.

Here, the attempt to rescue a wireless channel means that even if there is no activation input for a communication method capable of communicating with the external device 500 from the user, the wireless communication unit 110 automatically selects a specific communication method by the mobile controller 180. It means to activate it.

For example, when the mobile terminal 100 wants to communicate with the external device 500 according to the Bluetooth method, in general, an input for determining a wireless communication method of the mobile terminal 100 by the user and the corresponding communication An input is required to activate the mode. However, according to an embodiment of the present invention, when a change in the magnetic field is sensed as the controller 180 approaches the external device 500, the wireless communication method is determined so that communication is automatically performed in the Bluetooth method even if there is no input. Can be controlled.

In this case, when the external device 500 is scanned through the wireless communication unit 110, the controller 180 may control the wireless communication unit 110 to attempt to establish a wireless channel with the scanned external device 500. . When the wireless communication unit 110 attempts to establish a wireless channel with the external device 500 and forms a channel with the external device 500 according to a specific communication method, the establishment of the wireless channel is completed.

In some cases, the controller 180 additionally informs the external device 500 of the communication method of the wireless channel to be established by the wireless communication unit 110, and transmits a message requesting that the external device 500 activate the corresponding communication mode. It can be controlled as much as possible.

7 is an exemplary diagram for a preset gesture input according to an embodiment of the present invention. Also, FIG. 8 is an additional exemplary diagram for a preset gesture input according to an embodiment of the present invention.

In the description of FIGS. 4 to 6, when the controller 180 approaches the external device 500, a change in magnetic field is sensed, and the wireless communication unit 110 attempts to establish a wireless channel. However, for example, even when a plurality of external devices 500 exist, a geomagnetic sensor malfunctions, or a user does not want wireless communication with the external device 500, the mobile terminal 100 and the external device An unnecessary wireless channel may be established between 500.

In addition to the above example, it is necessary to prevent the mobile terminal 100 from attempting to establish a wireless channel too frequently with the external device 500 for power saving. To this end, the controller 180 may control the wireless communication unit 110 to attempt to establish a wireless channel with the external device 500 only when a preset gesture input is received. That is, while a change in the magnetic field is being detected through the sensing unit 140, when an additional preset gesture input is received, the controller 180 provides the wireless communication unit 110 to the external device 500 and the wireless channel. Can be controlled to attempt to build.

To this end, the mobile terminal 100 may include a memory 160 and the controller 180 may control to store at least one preset gesture input in the memory 160. In addition, the controller 180 may preset a specific gesture sensed through the sensing unit 140 as an input for causing the wireless communication unit 110 to attempt to establish a wireless channel.

In this case, the sensing unit 140 may include various sensors for detecting a gesture input. For example, the sensing unit 140 may include a touch sensor, a proximity sensor 141, an acceleration sensor, a magnetic sensor, a gravity sensor, a gyroscope sensor, a motion sensor, etc., and the pressure applied to the mobile terminal 100 It may also be provided with a pressure sensor capable of sensing.

In FIG. 7A, a knock operation is illustrated as an example of a preset gesture input. When a gesture input for tapping the mobile terminal 100 is received by the user from the external device 500 for which a wireless channel is to be established, the controller 180 allows the wireless communication unit 110 to establish a wireless channel with the external device 500 accordingly. You can control to try.

In this case, the preset gesture input may be an operation in which an external shock is applied to the mobile terminal 100. The controller 180 may determine whether such a knock operation corresponds to a preset gesture input using at least one of an acceleration sensor gyroscope sensor, a gravity sensor, and a pressure sensor.

In addition, according to a user or manufacturer's setting, a plurality of preset knock operations may be determined as the preset gesture input. In this case, the controller 180 may determine that a preset gesture input is received when a predetermined continuous knock operation is detected through the sensing unit 140.

7B is a graph representing a state change of the mobile terminal 100 determined by the controller 180. In (b) of FIG. 7, for convenience of explanation, specific numerical values are omitted. Referring to (b) of FIG. 7, when a specific value (710, 720) compared to the reference value 700 is detected through the sensing unit 140, the controller 180 may determine that there is a preset gesture input. have.

Here, the reference value 700 is the state of the mobile terminal 100 determined by the controller 180 when a specific sensor for detecting a specific change provided by the sensing unit 140 detects a change less than a threshold value. Means the value expressed as a numerical value.

For example, when a specific sensor is an acceleration sensor, and when the change in acceleration sensed through it is less than or equal to a threshold value, the controller 180 may determine that there is no change in acceleration of the mobile terminal 100, and this is expressed as a numerical value. One may correspond to the reference value 700.

On the other hand, when a specific sensor of the sensing unit 140 detects a change amount exceeding a threshold value, the controller 180 can determine the change in acceleration of the mobile terminal 100, and expressing this as a numerical value is a specific value compared to the reference value. It may correspond to the values (710, 720).

For example, when a knock operation is received twice as shown in (a) of FIG. 7 through a preset gesture input, the controller 180 uses the sensing unit 140 to provide two specific values compared to the reference value 700 It can be determined that (710, 720) has been input. In this case, the controller 180 may control the wireless communication unit 110 to attempt to establish a wireless channel with the external device 500 on which the knock operation has been performed.

As an example of a preset gesture input in FIG. 8A, a sweep operation is illustrated. When a gesture input that the mobile terminal 100 swipes is received to the external device 500 for which the user wishes to establish a wireless channel, the controller 180 provides the wireless communication unit 110 to communicate with the external device 500 accordingly. You can control to try to establish a channel.

In this case, the preset gesture input may be a motion of the mobile terminal 100 and an operation in which an external contact is detected for a predetermined time on the mobile terminal 100. The controller 180 may determine whether such a sweep operation corresponds to a preset gesture input using at least one of an acceleration sensor gyroscope sensor, a gravity sensor, a pressure sensor, a touch sensor, and a proximity sensor 141. have.

Further, the preset gesture input may include not only one type of operation but also a plurality of operations. For example, the preset gesture input may include a sweep operation performed while the user grips the mobile terminal 100 tightly (squeeze operation) and the gripping operation is maintained.

As an example of a preset gesture input in (b) of FIG. 8, a shaking operation is shown. When the user approaches the external device 500 for which a wireless channel is desired to be established and a gesture input for shaking the mobile terminal 100 is received, the controller 180 provides the wireless communication unit 110 to the external device 500 and the wireless channel. You can control to try to build.

In this case, the preset gesture input may be an operation to detect a change in the direction of the mobile terminal 100. A description of the sensing unit 140 for detecting this will be replaced with the items described in (a) of FIG. 8.

In addition, as an example of a preset gesture input in (c) of FIG. 8, a scanning operation is illustrated. When the mobile terminal 100 contacts the external device 500 for which the user wishes to establish a wireless channel or maintains proximity within a predetermined range, and receives the movement of the mobile terminal 100, the controller 180 The communication unit 110 may be controlled to attempt to establish a wireless channel with the external device 500.

The preset gesture input and the operation of the controller 180 therefor are similar to the case of FIG. 8B, and thus will be omitted.

As described above in the description of FIGS. 7 and 8, even while a preset gesture input is input, the controller 180 can detect a change in the magnetic field through the sensing unit 140 as it approaches the external device 500. have. That is, when a magnetic field change is sensed as a first condition and a preset gesture input is received as a second condition, the controller 180 controls the wireless communication unit 110 to attempt to establish a wireless channel with the external device 500. Explained that it can be done.

However, the controller 180 may control the wireless communication unit 110 to attempt to establish a wireless channel with the external device 500 by detecting only a change in the magnetic field even if there is no preset gesture input. That is, whether to add the preset gesture input as an additional condition for attempting to establish a radio channel may be determined according to a user or manufacturer's setting.

In the description of FIGS. 5 to 8, a method in which the controller 180 attempts to establish a wireless channel with one external device 500 has been described. However, even when the mobile terminal 100 is close to a plurality of external devices as well as one external device, the controller 180 attempts to establish a wireless channel with any one of the plurality of external devices in the above-described manner. I can. This will be described later in the description of FIG. 9.

9 is an exemplary view illustrating a method of establishing a communication channel with any one of at least one external device by a mobile terminal according to an embodiment of the present invention.

In FIG. 9A, a case in which the mobile terminal 100 is close to a plurality of external devices 500, 510, 520, 530, and 540 is illustrated as an example. As the mobile terminal 100 approaches the plurality of external devices 500, 510, 520, 530, and 540, the controller 180 may detect a change in the magnetic field through the sensing unit 140.

In this case, the controller 180 may control the wireless communication unit 110 to attempt to establish a wireless channel with at least one of the plurality of external devices 500, 510, 520, 530, and 540. At this time, the wireless communication unit 110 may scan a plurality of external devices 500, 510, 520, 530, and 540, and the controller 180, the wireless communication unit 110, a plurality of external devices 500, 510, Among 520, 530, and 540, it is possible to control to attempt to establish a wireless channel with an external device having the strongest received signal strength.

That is, the controller 180 determines the strength of signals received from a plurality of external devices 500, 510, 520, 530, and 540, and controls to attempt to establish a wireless channel with an external device receiving the strongest signal. I can. In this case, when a plurality of external devices 500, 510, 520, 530, 540 are scanned through the wireless communication unit 110, the control unit 180 determines the strength of the received signal based on the RSSI (Received Signal Strength Indicator). Can be compared. For example, when the external device having the strongest RSSI reception signal is the audio 500, the controller 180 may control the wireless communication unit 110 to attempt to establish a wireless channel with the audio 500.

Referring to FIG. 9B, the controller 180 may control a setting screen 503 for establishing a wireless channel to be displayed to a user through the touch screen 151. That is, as the mobile terminal 100 approaches a plurality of external devices 500, 510, 520, 530, and 540, the controller 180 provides a setting screen 503 to establish a wireless channel with any one of these devices. Can be controlled to be displayed.

In addition, the controller 180 may control to display a list of a plurality of external devices 500, 510, 520, 530, and 540 scanned through the wireless communication unit 110 on the setting screen 503. The controller 180 can control to display identification information (505, 515, 525, 535, 545) for a plurality of external devices 500, 510, 520, 530, 540 to be attempted to establish a wireless channel on the list. have. The identification information (505, 515, 525, 535, 545) includes names, serial numbers, MAC addresses, etc. of each of a plurality of external devices (500, 510, 520, 530, 540). ) May include at least one of identifying information. In FIG. 9B, identification information 505 of the external device 500, identification information 515 of the external device 510, identification information 525 of the external device 520, and identification of the external device 530 Information 535 and identification information 545 of the external device 540 are illustrated as examples.

In addition, the controller 180 detects the types of the scanned plurality of external devices 500, 510, 520, 530, 540 as a result of scanning for establishing a wireless channel, and the plurality of external devices 500, 510, 520, and 530, 540) It is possible to control such that icons indicating respective types are displayed on the list.

The controller 180 may control to display a radio channel establishment notification message on the list when establishment of a radio channel with at least one external device among the plurality of external devices 500, 510, 520, 530, and 540 is completed. In addition, the controller 180 may control a graphic effect to be applied to an area in which identification information on an external device for which a wireless channel is established is displayed on the list. The graphic effect may include various effects such as color, font, font size, and other image addition, and may be preset by the user. In this case, the controller 180 may control various graphic effects to be applied according to a communication method supported by the external device.

For example, when a wireless channel is established by a Bluetooth method or a wireless channel is established by a WiFi Direct method, the controller 180 may control the identification information to be displayed in different colors.

In the description of FIG. 9, according to the RSSI determination of the controller 180, an external device having the strongest received signal strength among a plurality of external devices 500, 510, 520, 530, 540 is determined as a target of attempting to establish a wireless channel. The case has been described.

However, as described above, as in the embodiments of FIGS. 7 and 8, the controller 180 receives a preset gesture input for any one of a plurality of scanned external devices 500, 510, 520, 530, and 540. Even if so, a target for attempting to establish a wireless channel may be determined. For example, among a plurality of external devices 500, 510, 520, 530, and 540 shown in FIG. 9A, the user 100 knocks on the external device 540 through the mobile terminal 100. Upon performing the operation, the controller 180 may determine that a preset gesture input has been received. In this case, the controller 180 may control the wireless communication unit 110 to attempt to establish a wireless channel with the external device 540 among the plurality of external devices 500, 510, 520, 530, and 540.

Whether to determine an attempt to establish a wireless channel based on signal strength among the plurality of external devices or based on a preset gesture input may be determined according to a user or manufacturer's setting.

10 is an exemplary diagram for explaining a method in which a mobile terminal determines a preset external device as a communication channel establishment target according to an embodiment of the present invention.

In FIG. 9, a case in which an external device with the strongest received signal strength based on RSSI is determined as a target to which the controller 180 attempts to establish a wireless channel has been described. However, when an external device preset by the user exists, The controller 180 may control the wireless communication unit 110 to attempt to establish a wireless channel with a preset external device.

In FIG. 10A, it is assumed that the external device preset by the user is the external device 510.

The controller 180 detects a change in a magnetic field as it approaches a plurality of external devices 510 and 520, and controls the wireless communication unit 110 to attempt to establish a wireless channel with any one of the plurality of external devices 510 and 520. Can be controlled. When there is no preset for the external device from the user, the controller 180 attempts to establish a wireless channel with an external device having a strong received signal as described above in the description of FIG. 9. Can be controlled. If the signal from the external device 520 is strong, the mobile terminal 100 establishes a wireless channel with the external device 520.

However, when the external device 510 is an external device preset by the user, the controller 180 preferentially attempts to establish a wireless channel with the external device 510 regardless of the strength of the received signal. Can be controlled.

Referring to FIG. 10B, when a plurality of external devices are scanned, the controller 180 displays a setting screen 503 for establishing a wireless channel through the touch screen 151. It can be controlled as much as possible.

The controller 180 may control a list of scanned external devices 510 and 520 to be displayed on the setting screen 503. The controller 180 may control to display identification information 515 and 525 for each of a plurality of external devices 510 and 520 that are targets for attempting to establish a wireless channel on the list. The identification information 505 may include information for the controller 180 to identify each of the scanned external devices 510 and 520. At this time, the controller 180 can control to display an icon 1010 indicating that the external device 510 is a preset external device together with the identification information 515 of the external device 510 when there is a preset external device 510 from the user. have. Through this, the user can see that the mobile terminal 100 attempts to establish a wireless channel with the external device 510 set in advance.

Referring to FIG. 10C, when a wireless channel between the external device 510 and the mobile terminal 100 set in advance is being established, the icon 1010 shown in FIG. 10B The icon 1020 to which the graphic effect is added may be controlled to be displayed. In this case, the controller 180 may control the identification information 525 of the external device 520 excluded from the target of establishing a wireless channel to not be displayed on the list.

On the other hand, in some cases, when a user input is received on the icon 1010 on the list 503 shown in FIG. 10B, the control unit 180 interoperates between the mobile terminal 100 and the external device 510. It can also be controlled to attempt to establish a wireless channel. That is, although the presence of the external device 510 set in advance is notified to the user through the icon 1010, the controller 180 may control to attempt to establish a wireless channel when a final selection input is received from the user.

Whether to attempt to establish a wireless channel automatically with a preset external device or to attempt to establish a wireless channel by receiving a user input may be determined according to a user or manufacturer setting.

11 is an exemplary diagram for explaining that a mobile terminal establishes a communication channel according to a communication channel establishment history according to an embodiment of the present invention. As shown in FIG. 9, it is assumed that a plurality of external devices 500, 510, 520, 530, and 540 are scanned through the wireless communication unit 110.

In this case, as the mobile terminal 100 approaches the plurality of external devices 500, 510, 520, 530, and 540, the controller 180 detects a change in the magnetic field, and the plurality of external devices 500, 510, 520 In order to establish a wireless channel with any one of the devices 530 and 540, the setting screen 503 may be displayed. The setting screen 503 includes a list of a plurality of scanned external devices 500, 510, 520, 530, 540, and includes a list of a plurality of external devices 500, 510, 520, 530, 540 that have been scanned. Identification information 505, 515, 525, 535, 545 may be included.
