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 of an object approaching a predetermined detection surface or an object existing in the vicinity of the detection surface without mechanical contact using an electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen. The proximity sensor 141 has a longer life than the contact type sensor and its utilization is also high.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. 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 act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor senses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, do.

The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, etc. of a touch object to be touched on the touch screen 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 transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 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 on 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.

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera 121, a photosensor, and a laser sensor. The camera 121 is a kind of camera sensor.

The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

In this case, the power supply unit 190 may use at least one of an inductive coupling method based on a magnetic induction phenomenon from an external wireless power transmission apparatus and a magnetic resonance coupling method based on an electromagnetic resonance phenomenon Power can be delivered.

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.

Referring to FIGS. 2 and 3, the disclosed mobile terminal 100 includes a bar-shaped terminal body. However, the present invention is not limited thereto and can be applied to various structures such as a folder type, a flip type, a slide type, a swing type, and a swivel type in which a watch type, a clip type, a glass type or two or more bodies are relatively movably coupled .

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

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

In addition, if 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 means 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, the wireless channel may be configured to allow the mobile terminal 100 to communicate with an external device via Bluetooth (TM), Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB) Near Field Communication, Wi-Fi (Wireless-Fidelity), and Wi-Fi Direct.

An attempt to construct the radio channel will be described later with reference to FIG. 5 (b).

FIG. 5 is a conceptual diagram for explaining a method of establishing a communication channel with an external device according to an embodiment of the present invention. FIG. 6 illustrates a change in a magnetic field sensed by a mobile terminal according to an embodiment of the present invention Fig.

Referring to FIG. 5A, the control unit 180 may sense a change in magnetic field as the mobile terminal 100 approaches the external device 500 through the sensing unit 140. FIG. That is, since the external device 500 is an electronic device capable of performing wireless communication, a magnetic field is generated 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.

At this time, the sensing unit 140 may include a geomagnetic sensor capable of sensing changes in magnetic fields of three axes. The geomagnetic sensor may sense a magnetic field in three directions (x, y, z) around the mobile terminal 100, and the controller 180 may sense at least one of the three magnetic fields through the geomagnetic sensor , It is possible to detect a change in the magnetic field.

6 is a graph for explaining the change of the magnetic field sensed by the tether sensor. For convenience of explanation, it is assumed that the magnetic fields 610, 620, and 630 in the three axial 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 changes in the magnetic field are shown. In particular, the reference line 602 refers to the time axis t, and it is assumed that the geomagnetic sensor of the sensing unit 140 does not detect magnetic field disturbance by the external device 500 when t = 0.

The x-axis magnetic field 610, the y-axis magnetic field 620 and the z-axis magnetic field 630 indicate respective magnetic field changes when the mobile terminal 100 approaches the external device 500 according to the passage of time . The circle 600 is for describing the amount of change of the triaxial magnetic field at a specific time, and is independent of the actual waveform. On the other hand, it can be seen that the magnetic field converges after a certain time has elapsed after being disturbed. The control unit 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 the change of the magnetic field. Hereinafter, a case where the control unit 180 determines magnetic field disturbance in accordance with a change in magnetic field will be described as an example.

As the 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 and converges at a predetermined magnitude, , And then converges to a constant value. The y axis 620 and the z axis 630 are shown by way of example in which the mobile terminal 100 has a waveform that increases and converges to a specific value as the mobile terminal 100 approaches the external device 500 at a predetermined magnitude .

The three-axis magnetic field change is merely an example, and the controller 180 does not sense that the magnetic field is perturbed only when the x-axis magnetic field, the y-axis magnetic field, and the z-axis magnetic field necessarily have the waveforms shown in Fig.

The x-axis magnetic field 610, the y-axis magnetic field 620, and the z-axis magnetic field 630, which have different values in the circle 600, converge to specific values while the magnetic field is changing in waveform as shown in FIG. 6 It can be seen that the waveform changes in scattered form. The control unit 180 can detect a change in the scattered waveform, that is, a change in the magnetic field, after converging at the circle 600 through the geomagnetic sensor. In this case, the control unit 180 can control the wireless communication unit 110 to attempt to construct a wireless channel.

6, the three-axis magnetic fields 610, 620, and 630 are all scattered. However, even when at least one magnetic field is disturbed, the controller 180 senses a change in the magnetic field, It is possible to control to attempt to construct a wireless channel.

Referring to FIG. 5B, the external device 500 is scanned through the wireless communication unit 110 as the magnetic field is detected. When at least one external device 500 is scanned, 151 to display a setting screen 503 for establishing a wireless channel. Here, the setting screen 503 refers to a screen including information related to a wireless channel establishing process, such as an attempt to establish a wireless channel, a wireless channel establishing progress, a communication scheme used for establishing a wireless channel, and the like. That is, it is a screen for informing the user of information related to the establishment of a wireless channel.

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

In addition, the controller 180 may detect the type of the scanned external device 500 as a result of the scanning for establishing the wireless channel, and may control the icon indicating the type of the external device 500 to be displayed on the list have. 5A, an external device to which the mobile terminal 100 is close is an audio device 500, and an audio icon indicating the external device 500 that is rendered in FIG. 5B is shown as an example .

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

Here, the attempt to resend the wireless channel means that the mobile communication unit 180 allows the wireless communication unit 110 to automatically transmit a specific communication method to the external device 500 even if the user does not have an activation input for the communication method capable of communicating with the external device 500 .

For example, when the mobile terminal 100 desires to communicate with the external device 500 in accordance with the Bluetooth method, generally, an input for determining the manner in which the mobile terminal 100 performs wireless communication from the user is determined by the Bluetooth method, An input to activate the mode is required. However, according to the embodiment of the present invention, when the change of the magnetic field is detected as the external device 500 approaches the external device 500, the control unit 180 automatically performs the communication using the Bluetooth method Can be controlled.

At this time, when the external device 500 is scanned through the wireless communication unit 110, the control unit 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 establishes a wireless channel with the external device 500 and forms a channel according to the specific communication method with the external device 500, the wireless channel is completed.

The control unit 180 notifies 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 the external device 500 to activate the communication mode .

7 is an exemplary diagram of a preset gesture input in accordance with an embodiment of the present invention. 8 is a further exemplary diagram of a pre-set gesture input in accordance with an embodiment of the present invention.

4 to 6, when the controller 180 approaches the external device 500, a change in the magnetic field is detected, and the wireless communication unit 110 attempts to establish a wireless channel. However, for example, when there are a plurality of external devices 500, when the geomagnetic sensor malfunctions, or when the user does not want to perform wireless communication with the external device 500, An unnecessary radio channel can be established between the base stations 500.

It is necessary to prevent the mobile terminal 100 from attempting to construct a radio channel too frequently with the external device 500 in order to save power as well as the above example. 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 predetermined gesture input is received. That is, when a predetermined gesture input is received while the change of the magnetic field is being sensed through the sensing unit 140, the controller 180 determines whether the wireless communication unit 110 is connected to the external device 500, In order to control the system.

For this, the mobile terminal 100 may include a memory 160, and the controller 180 may control the at least one preset gesture input to be stored in the memory 160. In addition, the control unit 180 may set the gesture detected through the sensing unit 140 as an input for causing the wireless communication unit 110 to attempt to construct a wireless channel.

In this case, the sensing unit 140 may include various sensors for sensing 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, and a motion sensor. The pressure applied to the mobile terminal 100 A pressure sensor capable of sensing the pressure of the fluid.

In FIG. 7 (a), a knock operation is shown as an example of a preset gesture input. When the user receives a gesture input to tap the mobile terminal 100 to the external device 500 that desires to establish a wireless channel, the controller 180 controls the wireless communication unit 110 to establish a wireless channel with the external device 500 You can control to try.

At this time, the predetermined gesture input may be an operation that an external impact is applied to the mobile terminal 100. [ The controller 180 may determine whether the knock operation corresponds to a predetermined gesture input by using at least one of an acceleration sensor gyroscope sensor, a gravity sensor, and a pressure sensor.

Also, according to the setting of the user or the manufacturer, a predetermined plurality of consecutive knocking operations may be determined as the preset gesture input. In this case, when the predetermined knocking operation is sensed through the sensing unit 140, the controller 180 may determine that a preset gesture input is received.

7 (b) is a graph showing a state change of the mobile terminal 100 judged by the controller 180. FIG. For convenience of explanation in FIG. 7 (b), specific numerical values are omitted. Referring to FIG. 7B, when the specific values 710 and 720 are detected with respect to the reference value 700 through the sensing unit 140, the controller 180 determines that there is a predetermined gesture input have.

Herein, the reference value 700 indicates a state of the mobile terminal 100 judged by the controller 180 when a specific sensor for sensing a specific change of the sensing unit 140 senses a change below a threshold value Quot; is a numerical value.

For example, when the specific sensor is an acceleration sensor, the controller 180 may determine that there is no acceleration change of the mobile terminal 100, and if the change of the acceleration detected through the acceleration sensor is below the threshold value, May correspond to the reference value 700.

On the other hand, when the specific sensor of the sensing unit 140 detects a change amount exceeding the threshold value, the control unit 180 can determine the acceleration change of the mobile terminal 100, Values 710 and 720, respectively.

For example, when two knocking operations are received as shown in FIG. 7 (a) with a predetermined gesture input, the controller 180 controls the sensing unit 140 to generate two specific values (710, 720) are input. In this case, the control unit 180 can control the wireless communication unit 110 to attempt wireless channel establishment with the external device 500 that has performed the knocking operation.

A sweep operation is shown as an example of a preset gesture input in Figure 8 (a). The control unit 180 controls the wireless communication unit 110 to transmit the gesture input to the external device 500 through the wireless communication unit 110. [ It is possible to control to try to construct a channel.

The gesture input may be a movement of the mobile terminal 100 and an operation of detecting an external contact with the mobile terminal 100 for a predetermined time. The control unit 180 can determine whether the sweep operation corresponds to a preset gesture input by using at least one of the acceleration sensor gyroscope sensor, the gravity sensor, the pressure sensor, the touch sensor, and the proximity sensor 141 have.

In addition, the preset gesture input may include not only one kind of operation but also a plurality of operations. For example, the predetermined gesture input may include a sweep operation performed while the user holds the mobile terminal 100 (squeeze operation) and the gripped operation is maintained.

A shaking operation is shown as an example of a preset gesture input in Figure 8 (b). The control unit 180 controls the wireless communication unit 110 to transmit the gesture input to the external device 500 and the wireless channel to the wireless communication unit 110. [ You can control to try to build.

At this time, the preset gesture input may be an operation for detecting a change in the direction of the mobile terminal 100. The description of the sensing unit 140 for sensing this will be replaced with the description of FIG. 8 (a).

In addition, a scanning operation is shown as an example of a preset gesture input in Fig. 8 (c). When the user receives movement of the mobile terminal 100 while the mobile terminal 100 is in contact with the external device 500 wishing to establish a wireless channel or while the mobile terminal 100 remains within a predetermined range, It is possible to control the communication unit 110 to attempt to establish a wireless channel with the external device 500.

The gesture input and the operation of the controller 180 are similar to those of FIG. 8 (b), so that they are omitted.

7 and 8, the controller 180 can sense the change in the magnetic field through the sensing unit 140 as the controller 180 approaches the external device 500 while the preset gesture input is being input have. That is, when a change in the magnetic field is detected under the first condition and a preset gesture input in the second condition is received, the controller 180 controls the wireless communication unit 110 to attempt to establish a wireless channel with the external device 500 .

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

In the description of FIGS. 5 to 8, a description has been given of the manner in which the controller 180 attempts to establish a wireless channel with one external device 500. However, even when the mobile terminal 100 is close to not only one external device but also a plurality of external devices, the control unit 180 attempts to establish a wireless channel with any one of the plurality of external devices in the above- . This will be described later in the description of FIG.

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

In this case, the control unit 180 may control the wireless communication unit 110 to attempt wireless channel establishment with at least one of the plurality of external devices 500, 510, 520, 530, and 540. In this case, the wireless communication unit 110 may scan a plurality of external devices 500, 510, 520, 530, and 540, and the control unit 180 may control the wireless communication unit 110 to communicate with a plurality of external devices 500, 510, 520, 530, and 540 can be controlled 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 a signal received from the plurality of external devices 500, 510, 520, 530, and 540, and controls the external device to attempt to establish a wireless channel with the external device . In this case, when a plurality of external devices 500, 510, 520, 530 and 540 are scanned through the wireless communication unit 110, the controller 180 controls the intensity of the received signal based on 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. 9 (b), the controller 180 may control the user to display a setting screen 503 for establishing a wireless channel through the touch screen 151.

The control unit 180 may also control the display of 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 controls the display of the identification information 505, 515, 525, 535, and 545 for a plurality of external devices 500, 510, 520, 530, have. The identification information 505, 515, 525, 535, and 545 indicates the name of each of the plurality of external devices 500, 510, 520, 530, and 540, the serial number, And the like). 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, identification of the external device 530 The information 535 and the identification information 545 of the external device 540 are shown by way of example.

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

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

9, an external device having the strongest received signal strength among a plurality of external devices 500, 510, 520, 530, and 540 is determined as a target of a wireless channel establishment attempt according to the RSSI determination of the controller 180 .

For example, when the user 100 knocks over the external device 540 through the mobile terminal 100 out of the plurality of external devices 500, 510, 520, 530, and 540 shown in FIG. When the operation is performed, the controller 180 can determine that a preset gesture input has been received. In this case, the control unit 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 a target of building a wireless channel based on the signal strength among the plurality of external devices or based on a preset gesture input may be determined according to a setting of a user or a manufacturer.
