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 the presence of an object in the vicinity of the detection surface, without mechanical contact by using 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.

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 uses 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, Detection.

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

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and 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 touching 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 sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is arranged to scan the motion of the object to be sensed 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.

As shown in FIG. 1A, a mobile terminal according to the present invention includes Bluetooth ™, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), UWB (Ultra Wideband), ZigBee, NFC Field Communication), and Wireless USB (Wireless Universal Serial Bus).

Among them, the NFC module provided in the mobile terminal supports the non-contact type short-range wireless communication between the terminals at a distance of about 10 cm. The NFC module may operate in either a card mode, a reader mode, or a P2P mode. In order for the NFC module to operate in the card mode, the mobile terminal 100 may further include a security module for storing card information. Here, the security module may be a physical medium such as a UICC (e.g., a SIM (Subscriber Identification Module) or a USIM (Universal SIM)), a Secure micro SD and a sticker, or a logical medium For example, embeded SE (Secure Element)). Data exchange based on SWP (Single Wire Protocol) can be made between NFC module and security module.

When the NFC module is operated in the card mode, the mobile terminal can transmit the stored card information to the outside such as a conventional IC card. Specifically, if the mobile terminal storing the card information of the payment card such as a credit card or a bus card is brought close to the fare payment machine, the mobile local payment can be processed, and the mobile terminal storing the card information of the access card can be accessed If you are close to the time, the approval process for access may begin.

Through P2P communications, data such as business cards, contact information, digital photos, URLs in electronic form, and setup parameters for Bluetooth and Wi-Fi connectivity can be exchanged. However, since the usable distance of NFC communication is short, the P2P mode can be effectively used to exchange small-sized data.

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

FIG. 2 is a flowchart for explaining a control method of a mobile terminal according to a first embodiment of the present invention, and FIGS. 3 to 4 are views for explaining a control method of the mobile terminal according to the first embodiment of the present invention .

According to the first embodiment of the present invention, it is possible to measure the bioimpedance using two different mobile terminals. At this time, two different mobile terminals may be selected among wearable electronic devices such as a mobile phone, a watch phone, and a glass type mobile terminal. It is assumed that two different mobile terminals each have two or more electrodes.

Referring to FIG. 2, when the controller 180 of the mobile terminal senses the contact of the human body through the first electrode and the second electrode formed in the mobile terminal (S110), the controller 180 controls the external electronic device (S120), and transmits a human body communication activation signal to an external electronic device (S130).

The controller 180 may sense the contact of one of the first end or the second end of the human body through the first electrode and the second electrode. At this time, the control unit 180 can confirm whether the same end portion is detected in the first electrode and the second electrode by outputting or receiving a specific signal. Here, the first end or the second end may represent the distal end of the left body and the distal end of the right body, or the distal end of the body, respectively. For example, the first end may represent the right finger and the second end may represent the left finger.

When activating the human body communication, the controller 180 may detect an external electronic device capable of performing human body communication. Specifically, the control unit 180 may sense the electronic device in contact with the first and second electrodes and the opposite human body in contact with the second electrode. In addition, the control unit 180 can detect another external electronic device in which human body communication is activated through a local communication method.

Human Body Communication (Human Body Communication) is a technology to wirelessly connect wearable or implantable sensors or devices, and the human body can be used as a communication medium.

The control unit 180 can transmit the human body communication activation signal to the sensed external electronic device and receive a response thereto, thereby confirming the human body communication activation state with each other.

The control unit 180 of the mobile terminal outputs a first signal to a human body contacting the first electrode through the first electrode at step S140 and measures a human received signal of the first signal received through the human body through the second electrode And can be set as a reference signal (S150).

The control unit 180 outputs a voltage having a magnitude and a frequency set for the bioimpedance measurement through the first electrode in a state where one end of the human body is in contact with the first electrode and the second electrode at the same time, The human received signal of the first signal output to the first electrode can be measured. In general, even if the controller 180 outputs the first voltage as the first signal through the first electrode, the voltage of the first magnitude is not received by the human body. Therefore, the control unit 180 needs to measure the human received signal, which is a part of the first signal, which is substantially received by the human body. That is, the controller 180 can obtain a signal input to one end of the human body in contact with the first electrode and the second electrode by measuring the human received signal with respect to the first signal. The description of the region in which the first electrode and the second electrode are formed is merely an example, and may be formed on another surface of the mobile terminal.

The control unit 180 may measure the human received signal for the first signal as a reference signal. The reference signal may be used to compare a second signal that has passed through a human body and then transmitted back through an external electronic device.

The control unit 180 may output the first signal to the human body contacted with the first electrode and the second electrode, and then convert human body communication into a standby state or a disabled state.

The control unit 180 of the mobile terminal receives the activation signal of the human body communication from the external electronic device (S160) and receives the second signal from the human body in contact with the second electrode through the second electrode (S170) .

The external electronic device can acquire the first signal output from the first electrode of the mobile terminal through the human body and at the first electrode of the external electronic device which is in contact with the opposite end of the human body. The external electronic device receives the reduced second-size voltage while passing through the human body. At this time, the frequency of the received signal (hereinafter, referred to as 'third signal') is the same as that of the first signal.

When receiving the third signal, the external electronic device can transmit an activation signal of human body communication to change the human body communication back to the active state to the mobile terminal side.

An external electronic device may transmit an activation signal of human body communication and then output a fourth signal through a second electrode of the external electronic device. The fourth signal is a signal generated so that the human received signal is equal to the third signal in consideration of the difference between the first signal and the reference signal. Here, the first signal to the fourth signal are signals transmitted or received to measure the bioimpedance, and have the same specific frequency.

The control unit 180 of the mobile terminal can acquire the second signal that is received through the second electrode of the mobile terminal through the human body by the fourth signal output from the second electrode of the external electronic apparatus.

The controller 180 of the mobile terminal can measure the bioimpedance using the previously acquired reference signal and the second signal (S180).

The controller 180 may measure the bioimpedance using the difference between the reference signal, which is a human received signal for the first signal, and the second signal, which is received by the second electrode of the mobile terminal. Here, the bioimpedance means the total resistance of the bio-conductive to the alternating current. The bioimpedance can be calculated by equally dividing the difference between the reference signal and the second signal and dividing by the current value. The bioimpedance can be applied to various analysis models to obtain body water amount, body fat amount, and the like.

The first electrode and the second electrode of the mobile terminal or the electronic device may be at least one of an antenna region having a conductive material formed in an externally exposed region, a front operation key or a rear operation key, or an electrode formed separately for human body communication .

The first electrode and the second electrode of the mobile terminal or the electronic device may be physically formed of two electrodes. In addition, the first electrode and the second electrode of the mobile terminal or the electronic device may be formed of one physical electrode including two distinct regions.

When the first electrode and the second electrode are formed as one physical electrode, the control unit 180 may generate a control signal to switch the transmission or reception function between the two divided regions.

The mobile terminal or the electronic device may further include a third electrode. When sensing the contact of the human body with the third electrode, the mobile terminal or the electronic device may transmit the mutual terminal information, the human body communication activation signal, Information can be transmitted and received. Here, the information on the first signal may include information on the human received signal. At this time, the third electrode can be used as a channel for transmitting a human body communication activation signal.

When the measurement of the bioimpedance is completed, the controller 180 may control the display unit to display the bioimpedance. The control unit 180 can display the analysis results using the bioimpedance together.

Referring to FIG. 3, the first and second electrodes 132a and 132b of the first mobile terminal 100A are simultaneously contacted with the first finger, and the first and second electrodes 123a and 123b of the second mobile terminal 100B And 123b are simultaneously contacted with the second finger to measure the bioimpedance through human body communication.

The first and second electrodes 132a and 132b of the first mobile terminal 100A may be an antenna region formed on a side surface of the rear frame and exposed to the outside. Although not shown in detail, as shown in FIG. 1B, the first and second electrodes 132a and 132b may be formed with an antenna pattern.

Also, the first and second electrodes 123a and 123b of the second mobile terminal 100B may be a rear operation key formed on the rear cover of the mobile terminal. In this case, unlike FIG. 1B, the first and second electrodes 123a and 123b may be formed of one electrode.

When a part of the human body simultaneously contacts the first and second electrodes 132a and 132b of the first mobile terminal 100A and the first and second electrodes 123a and 123b of the second mobile terminal 100B, The control unit of the first mobile terminal 100A and the second mobile terminal 100B can switch the human body communication to the active state.

The control unit of the first mobile terminal 100A outputs the first signal to the human body through the first electrode 132a of the first mobile terminal and acquires the human received signal received through the human body through the second electrode 132b Can be set as a reference signal. After setting the reference signal, the first mobile terminal 100A may convert the human body communication into a standby state or an inactive state.

The control unit of the second mobile terminal 100B may receive the third signal that has passed through the human body through the first electrode 123a of the second mobile terminal 100B. When the second mobile terminal 100B receives the third signal, it can transmit an activation signal to activate the human body communication with the first mobile terminal 100A.

If the control unit of the second mobile terminal 100B receives a response to the human body communication activation signal from the first mobile terminal 100 A, the control unit of the second mobile terminal 100B generates a fourth signal using the third signal, 100B through the second electrode 123b. Here, the fourth signal may be a signal obtained by amplifying the third signal in consideration of the difference between the first signal and the reference signal.

The first mobile terminal 100A may receive a second signal that has passed through the human body and compare it with a reference signal to provide a bioimpedance.

4, when the controller 180 of the mobile terminal senses contact of the human body through the first electrode and the second electrode, the control unit 180 activates the human body medium communication, Can be detected.

At this time, the controller 180 may display the muscle impedance, body fat, BMI, and the like on the display unit 151 as a result of the bioimpedance analysis.

FIG. 5 is a flowchart illustrating a method of controlling a mobile terminal according to a second embodiment of the present invention. FIG. 6 is a diagram illustrating a method of controlling a mobile terminal according to a second embodiment of the present invention.

According to the second embodiment of the present invention, a living body impedance can be measured using one mobile terminal. At this time, the mobile terminal may be a wearable electronic device such as a mobile phone, a watch phone, or a glass type mobile terminal.

Referring to FIG. 5, the controller 180 of the mobile terminal simultaneously detects the contact between the first end and the second end of the human body through the first electrode unit and the second electrode unit formed at the mobile terminal (S210). Here, the first end or the second end may represent the distal end of the left body and the distal end of the right body, or the distal end of the body, respectively. For example, the first end may represent the right finger and the second end may represent the left finger. Further, the first end portion may indicate the right thumb and the second end portion may indicate the right index finger.

The control unit 180 may activate the human body communication when the first and second electrode units exposed to the outside of the mobile terminal simultaneously contact different ends of the human body.

The control unit 180 may output a specific signal to one of the first electrode unit and the second electrode unit and then measure the reception time of the specific signal at the opposite electrode unit to determine whether the distal ends of the human body are in contact with each other at the same time. In addition to the above-described method, it is possible to determine whether different end portions of the human body are simultaneously in contact with each other using different sensing information.

The first electrode portion and the second electrode portion may be formed of two electrodes physically separated or may be formed of one physical electrode including two divided regions. The controller 180 may generate a control signal for switching the functions of the first electrode unit and the second electrode unit to perform a transmitting or receiving function. In particular, when the first electrode unit and the second electrode unit are formed as one physical electrode, the controller 180 can control the two divided regions to switch the transmission or reception function.

The first electrode portion and the second electrode portion may be one of an antenna area formed to be symmetrical to the outer surface of the terminal side or an operation key formed to be symmetrical to the back side of the terminal. At this time, the first electrode unit and the second electrode unit may include two or more separated electrodes.

When sensing the contact of the human body with the first and second electrode units, the control unit 180 of the mobile terminal can switch to an operation mode for performing human body communication (S220).

The first electrode portion and the second electrode portion of the mobile terminal may be formed on only one of the antenna area or the rear operation key formed symmetrically on the side surface of the terminal, or both.

When the first electrode unit and the second electrode unit are both formed in the antenna area and the rear operation key, the controller 180 may sense the contact of the human body in the symmetrical antenna area or the operation key area at the same time to activate the human body communication. That is, the control unit 180 may contact one end of the human body with the antenna area, and may not determine that the other end is in contact with the rear operation key. The description of the regions in which the first electrode portion and the second electrode portion are formed is merely an example and may be formed on another surface of the mobile terminal.

Specifically, the controller 180 obtains the contact pressure of the human body when the contact of the human body is detected through the operation key formed on the rear surface of the terminal, and when the contact pressure is less than the threshold value, Mode. That is, when the contact pressure for the operation key formed on the rear surface is less than the threshold value, the control unit 180 recognizes that the operation key functions as a touch key, and when the contact pressure is equal to or greater than the threshold value, .

The controller 180 of the mobile terminal may output the first signal to the first terminal portion contacting the first electrode portion at step S230 and measure the human received signal of the first signal through the first electrode portion to set the reference signal as the reference signal (S240).

Specifically, when the first electrode unit and the second electrode unit are divided into the transmitting electrode and the receiving electrode, the controller 180 outputs the first signal through the transmitting electrode of the first electrode unit, and the receiving electrode of the first electrode unit The human received signal of the first signal can be measured. As described above, since all of the first signals output through the transmission electrodes of the first electrode unit can not be transmitted to the human body and some of the first signals are reflected, it is necessary to measure the signals substantially received by the human body.

When the first electrode unit and the second electrode unit are formed as one electrode, the controller 180 sets the function of the first electrode unit to the transmission mode, and then transmits the first signal to the first terminal unit contacting the first electrode unit Can be output. When the output of the first signal is completed, the control unit 180 changes the function of the first electrode unit to the reception mode and sets the reference signal to the human received signal of the first signal through the first electrode unit.

The control unit 180 of the mobile terminal receives the second signal from the second terminal portion contacting the second electrode unit (S250), and measures the bioimpedance using the reference signal and the second signal (S260).

The control unit 180 can receive the second signal, which is an output signal that the reference signal passes through the human body and is output from the second electrode unit. The controller 180 may obtain the bioimpedance by dividing the difference between the reference signal and the second signal by the current value. Here, the first signal, the reference signal, and the second signal may be AC voltages having the same specific frequency and different sizes.

When the measurement of the bioimpedance is completed, the controller 180 may control the display unit to display the bioimpedance. That is, the controller 180 can measure the bioimpedance while keeping the display unit in an inactive state during bioimpedance measurement. Also, the controller 180 can output the measurement result through the sound output unit while keeping the display unit in the inactive state.

Referring to FIG. 6, the controller 180 of the mobile terminal may measure the bioimpedance through human body communication by contacting the first electrode unit and the second electrode unit at the first end and the second end of the human body at the same time.

The mobile terminal may be a mobile phone 100 or a bogie type watch phone 300.

When the mobile terminal is the mobile phone 100, the first electrode unit is the antenna area 132a or 132b formed on the first side of the mobile terminal and the second electrode unit is the antenna area 132c or 132d formed on the second side of the mobile terminal. Lt; / RTI > In addition, the first electrode unit and the second electrode unit may be rear operation keys. At this time, if the first electrode portion and the second electrode portion each include two electrodes, an electrode portion can be formed as shown in FIG. 1C.

When the mobile terminal is a bogie type watch phone 300, the first electrode unit and the second electrode unit may be formed on the operation keys 323a and 323b formed on the upper portion or the lower portion of the display unit 351. Each of the operation keys 323a and 323b may be physically formed of two electrodes or may be divided into two electrode regions as described in the rear operation key.

6A). Alternatively, the control unit 180 may connect the right and left distal fingers to the first electrode unit and the second electrode unit at the same time (Fig. 6 (b), (c)).

According to the present invention, it is possible to provide a bioimpedance measurement function by using an electrode formed in a mobile terminal using a function such as telephone conversation or message transmission as a main function.
