Description

CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims the benefit under 35 U.S.C. §119(a) of a Korean patent application filed on Feb. 16, 2015 in the Korean Intellectual Property Office and assigned Serial number 10-2015-0023713, the entire disclosure of which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to an electronic device and a method of measuring biometric information. More particularly, the present disclosure relates to an electronic device and a method capable of measuring accurate biometric information regardless of an electrode array of electrodes.

BACKGROUND

Recently, as interest in health increases, many people carry a device to measure and immediately identify their own biometric information, thereby increasing demands for management of their own health. According to the demands, a portable biometric information measuring device by which the user can determine his/her own health at anytime and anywhere is spotlighted. To this end, the biometric information measuring device may be included in the form of a module in an electronic device, such as a portable terminal, which can be easily carried and conveniently used, or may be provided in the form of an application to be downloaded.

Such an electronic device for measuring biometric information can measure biometric information by attaching a plurality of electrodes to a corresponding part of the body or bringing the plurality of electrodes into contact with the corresponding part of the body according to the type of biometric information, analyze the measured biometric information, and immediately identify a health state through various provided biometric indexes and a body composition of the examinee. Accordingly, the examinee can determine his/her current health state through the provided biometric indexes and body composition and thus easily determine a checkup list which requires exercise, diet, rehabilitation treatment, or a complete medical examination according to the health state.

However, an electronic device for measuring biometric information of the related art has determined locations, directions, polarities, and electrode channel arrangements of a plurality of electrodes according to biometric information to be measured. Accordingly, in order to measure biometric information, a user or an examinee should grasp the locations, directions, polarities, and electrode channel arrangements of the plurality of electrodes and accurately place the electronic device on a body part required by each electrode.

If the electronic device is not placed on the required body part according to the locations, directions, polarities, and electrode channel arrangements of the plurality of electrodes, accurate biometric information cannot be measured and a biometric index and body composition analyzed based on the measured biometric information are not reliable. Further, in some cases, the measurement of biometric information may not be performed at all. Accordingly, the examinee or the user has to recognize in advance the locations, directions, polarities, and electrode channel arrangements of the plurality of electrodes to measure the accurate biometric information, so that the examinee or the user may feel difficulty, cumbersomeness, and inconvenience in measuring biometric information.

Therefore, a need exists for an electronic device and a method for measuring biometric information, which can acquire accurate biometric information regardless of an electrode array including locations, directions, polarities, and electrode channel arrangements of a plurality of electrodes.

The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

DETAILED DESCRIPTION

The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of various embodiments of the present disclosure as defined by the claims and their equivalents. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the various embodiments described herein can be made without departing from the scope and spirit of the present disclosure. In addition, descriptions of well-known functions and constructions may be omitted for clarity and conciseness.

The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the present disclosure. Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the present disclosure is provided for illustration purpose only and not for the purpose of limiting the present disclosure as defined by the appended claims and their equivalents.

It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces.

By the term “substantially” it is meant that the recited characteristic, parameter, or value need not be achieved exactly, but that deviations or variations, including for example, tolerances, measurement error, measurement accuracy limitations and other factors known to those of skill in the art, may occur in amounts that do not preclude the effect the characteristic was intended to provide.

In embodiments of the present disclosure, the expression “have”, “may have”, “include” or “may include” refers to existence of a corresponding feature (for example, a numerical value, a function, an operation, or components, such as elements), and does not exclude existence of additional features.

In embodiments of the present disclosure, the expression “A or B”, “at least one of A or/and B”, or “one or more of A or/and B” may include all possible combinations of the items listed. For example, the expression “A or B”, “at least one of A and B”, or “at least one of A or B” may include (1) at least one A, (2) at least one B, or (3) both at least one A and at least one B.

The expressions, such as “first”, “second”, and the like, used in various embodiments of the present disclosure may modify various elements regardless of order or importance, and do not limit corresponding elements. The above expressions are used merely for the purpose of distinguishing an element from the other elements. For example, a first user device and a second user device indicate different user devices although both of them are user devices. For example, a first element may be termed a second element, and similarly, a second element may be termed a first element without departing from the scope of the present disclosure.

It should be understood that when an element (for example, a first element) is referred to as being (operatively or communicatively) “connected,” or “coupled,” to another element (for example, a second element), it may be directly connected or coupled directly to the other element or any other element (for example, a third element) may be interposer between them. In contrast, it may be understood that when an element (for example, a first element) is referred to as being “directly connected,” or “directly coupled” to another element (i.e., the second element), there are no element (for example, the third element) interposed between them.

As used herein, the expression “configured to” may be interchangeably used with the expression “suitable for”, “having the capability to”, “designed to”, “adapted to”, “made to”, or “capable of”. The expression “configured to” may not necessarily mean “specially designed to” in terms of hardware. Alternatively, in some situations, the expression “device configured to” may mean that the device, together with other devices or components, “is able to”. For example, the phrase “processor adapted (or configured) to perform A, B, and C” may mean a dedicated processor (for example, an embedded processor) only for performing the corresponding operations or a generic-purpose processor (for example, a central processing unit (CPU) or an application processor (AP)) that can perform the corresponding operations by executing one or more software programs stored in a memory device.

Terms used in this specification are merely used to describe a specific embodiment and may not be intended to limit the scope of another element. As used herein, singular forms may include plural forms as well unless the context clearly indicates otherwise. Unless defined otherwise, all terms used herein, including technical terms and scientific terms, may have the same meaning as commonly understood by a person of ordinary skill in the art to which the present disclosure pertains.

The electronic device 200 according to various embodiments of the present disclosure may include a complex location sensor unit 210, a biometric information measurement unit 220, a switch unit 230, and a controller 280. Further, the electronic device 200 may further include a storage unit 240, an input unit 250, a display unit 260, and a communication unit 270.

The complex location sensor unit 210 may detect a plurality of pieces of location information (or a plurality of pieces of sensor information for calculating one piece of position (and/or location) information) on a measurement point. The complex location sensor unit 210 may include a plurality of location-based sensors, and may detect each of a plurality of pieces of location information (or a plurality of pieces of sensor information for calculating one piece of position (and/or location) information) on the measurement point from the plurality of location-based sensors. According to an embodiment of the present disclosure, the plurality of pieces of location information may include an acceleration value, a geomagnetic value, and an altitude value. Further, the plurality of pieces of location information may include location-based detection values detected from all the location-based sensors, such as a gyro detection value, an acceleration detection value, and a motion detection value, but are not limited thereto. The controller 280 may recognize a location and attitude of the electronic device 200 in the measurement point based on the plurality of pieces of location information detected by the complex location sensor unit 210 and determine a location, a direction, a polarity, and a channel of each of a plurality of electrodes according to the recognized location and attitude of the electronic device 200.

The biometric information measurement unit 220 may detect biometric information which an examinee desires to measure through a plurality of electrodes having an electrode array electrically connected thereto.

The electrode array includes locations, directions, polarities and/or the arrangement of electrode channels of the plurality of electrodes. For example, the electrode array may include a location, a direction, and/or a polarity arrangement of each electrode. The electrode array may include the arrangement of a current electrode channel to which the current is applied and/or a voltage electrode channel for measuring the voltage.

According to an embodiment of the present disclosure, the biometric information measurement unit 220 may detect biometric information (for example, a biometric signal) of the examinee from the plurality of electrodes of the preset electrode array controlled from the recognized electrode array according to the location and the attitude of the electronic device 200 recognized in the measurement point. According to an embodiment of the present disclosure, the biometric information measurement unit 220 may include a biometric signal measurement module 221 for detecting a biometric signal. The biometric signal measurement module 221 may detect the biometric signal of the examinee by placing the electronic device 200 at a certain location according to the biometric signal to be measured. For example, the biometric signal may include an electrocardiography (ECG) signal, an electroencephalogram (EEG) signal, an electrooculogram (EOG) signal, an electrogastrogram (EGG) signal, and an electromyography (EMG) signal.

The switch unit 230 may include a plurality of switches (or one switch including at least one input port and at least one output port) corresponding to the plurality of electrodes, respectively, and may electrically connect the plurality of electrodes and the biometric information measurement unit 220 through the plurality of switches. The switch unit 230 may be controlled to change the electrode array connected between the plurality of electrodes and the biometric information measurement unit 220 according to a control of the controller 280.

The controller 280 may recognize the electrode array of the plurality of electrodes formed in the electronic device 200 based on the plurality of pieces of location information detected in the measurement point and switch the recognized electrode array to correspond to a preset electrode array by controlling the switch unit 230. The controller 280 may analyze the biometric information detected by the biometric information measurement unit 220 electrically connected through the changed electrode array.

The controller 280 may recognize an electrode array of a plurality of electrodes according to a location and attitude of the electronic device 200 based on a plurality of pieces of location information detected by the complex location sensor unit 210 and, when at least one of the location, direction, polarity, and channel of at least one electrode is different from a preset electrode array based on a comparison between the recognized electrode array and the preset electrode array, change the electrode array of the plurality of electrodes such that the recognized electrode array of the plurality of electrodes corresponds to the preset electrode array of the plurality of electrodes. The controller 280 may detect the biometric information of the examinee from the biometric information measurement unit 220 through the changed electrode array of the plurality of electrodes.

For example, when two electrodes (for example, A and B) are formed on the rear surface of the electronic device 200 (see FIG. 4) and left and right directions and the polarity of each electrode are preset as the electrode array of the two electrodes, it is assumed that the electrode A is set as a (−) electrode in a left direction of the examinee and the electrode B is set as a (+) electrode in a right direction of the examinee. When the user or examinee places the electronic device 200 on the corresponding body part to measure the biometric information, if the preset left and right directions of the electronic device 200 are changed, the controller 280 may recognize that left and right directions of the two electrodes (A and B) of the electronic device 200 are also changed and control and change the switch unit 230 to make the electrode array of the recognized two electrodes (A and B) correspond to the preset electrode array, that is, to connect the electrode A in a right direction of the examinee as a (+) electrode and the electrode B in a left direction of the examinee as a (−) electrode.

The storage unit 240 may store in advance electrode array information on each electrode and basic information of the examinee. The electrode array information may include a location, direction, polarity, and arrangement of the electrode channel of each electrode. The basic information may include a name, an age, a gender, a height, and a weight of the examinee.

The input unit 250 may receive various input signals generated or input by the user or examinee. According to an embodiment of the present disclosure, the input unit 250 may include a key pad, a touch pad, and a voice input module, such as a microphone. Further, the input unit 250 is not limited thereto and may include all input means which can make an input into the electronic device 200 according to various embodiments of the present disclosure.

The display unit 260 may display, on a screen, a health state analysis result analyzed based on the biometric information detected by the biometric information measurement unit 220 through the electrode array of the plurality of electrodes controlled by the controller 280.

FIG. 3 is a block diagram illustrating a complex location sensor unit according to various embodiments of the present disclosure, and FIG. 4 illustrates a reference direction of an electronic device according to various embodiments of the present disclosure.

Referring to FIGS. 3 and 4, the complex location sensor unit 210 may include an acceleration sensor 302, a geomagnetic sensor 304, and an altimeter sensor 306.

The acceleration sensor 302 may detect an acceleration value in a measurement point when the electronic device 200 moves. According to the present disclosure, the acceleration sensor 302 may have three axes including a Y axis corresponding to a major axis length direction of the electronic device 200 based on the center of the electronic device 200, an X axis corresponding to a minor axis length direction of the electronic device 200, and a Z axis corresponding to a direction orthogonal to the plane (for example, the screen) with the X axis and the Y axis as illustrated in FIG. 4, and it is assumed that directions of the X axis, the Y axis, and the Z axis of the electronic device 200 are set as reference directions in a state where the Y axis is orthogonal to the horizontal plane, and the X axis and the Z axis are parallel to the horizontal plane. For example, the acceleration sensor 302 may have reference directions including an upward direction from the center of the electronic device 200, which is a +Y axis (a direction opposite thereto is a −Y axis), a rightward direction from the center of the electronic device 200, which is a +X axis (a direction opposite thereto is an −X axis), and a forward direction from the center of the electronic device 200, which is a +Z axis (a direction opposite thereto is a −Z axis).

The geomagnetic sensor 304 may detect a direction angle of the electronic device 200 by Earth's magnetic field in a measurement point where the electronic device 200 is located. According to the present disclosure, the geomagnetic sensor 304 may have reference angles having rotation angles (that is, direction angles) (for example, a pitch angle, a roll angle, and a yaw angle) of 0 degrees with respect to the X axis, the Y axis, and the Z axis of the electronic device 200 in a state where the geomagnetic sensor 304 has three axes equal to those of the acceleration sensor 302, and the Y axis is orthogonal to the horizontal plane and the X and Z axes are parallel to the horizontal plane as illustrated in FIG. 4. The controller 280 may recognize an attitude angle of the electronic device 200 through the geomagnetic value detected by the geomagnetic sensor 304.

The altimeter sensor 306 may detect an altitude (height) of the electronic device 200 by an air pressure at a measurement point where the electronic device 200 is located.

When the electronic device 200 measures biometric information in the measurement point, the controller 280 may recognize a direction, an angle, and an altitude for each axis in the measurement point based on the reference direction and angle for each axis of the complex location sensor unit 210, and thus recognize the location and attitude of the electronic device 200. Further, the controller 280 may determine locations and directions of a plurality of electrodes formed on at least one surface of the electronic device 200 according to the recognized location and attitude of the electronic device 200, and thus determine whether preset locations and directions of the plurality of electrodes are changed.

As described above, the controller 280 may recognize the location and attitude of the electronic device 200 in the measurement point based on the reference direction and the reference angle of each axis of the complex location sensor unit 210 by complexly using the plurality of pieces of location information (for example, the acceleration value, the geomagnetic value, and the altitude value) detected by the complex location sensor unit 210 and a combination thereof and, determine whether the electrode array (that is, the location, direction, polarity, and electrode channel arrangement) of the plurality of electrodes in the measurement point is changed according to the recognized location and attribute, and change the electrode array of the plurality of electrodes according to a result of the determination.

FIG. 5 illustrates a mounting of an electronic device on a body part according to various embodiments of the present disclosure.

Referring to FIG. 5, the electronic device 200 may measure a biometric signal by mounting two electrodes (electrode A and electrode B) formed on the rear surface of the electronic device 200 illustrated in FIG. 4 on a chest part to measure the biometric signal. For example, the biometric signal may be an ECG signal, and it may be assumed that the electrode A is set as the (−) polarity in a left direction of the examinee and the electrode B is set as the (+) polarity in a right direction of the examinee. In this case, the biometric signal as illustrated in FIG. 5 may be measured. Further, according to the present disclosure, even though left and right directions of the electronic device 200 are exchanged, that is, two electrodes are reversed, it is possible to detect the biometric information as illustrated in FIG. 5 by controlling the switch unit 230 to change locations and attitudes of the plurality of electrodes (A and B) into preset locations and attitudes according to the location and attitude of the electronic device 200 in a current measurement point.

FIG. 6 is a block diagram illustrating a controller according to various embodiments of the present disclosure.

Referring to FIG. 6, the controller 280 may include a measurement location recognition module 602, an electrode array determination module 604, a switch control module 608, and a biometric information analysis module 610.

The measurement location recognition module 602 may recognize the electrode array of the plurality of electrodes in the measurement point based on the plurality of pieces of location information (for example, the acceleration value, the geomagnetic value, and the altitude value) detected in the measurement point by the complex location sensor unit 210.

The measurement location recognition module 602 may first recognize the location and attitude of the electronic device 200 based on the pieces of location information detected in the measurement point. The measurement location recognition module 602 may calculate the direction and the angle of each axis changed from the reference direction and the reference angle of each axis of the complex location sensor unit 210 by using the acceleration value and the geomagnetic value detected in the measurement point and recognize the location and the attitude of the electronic device 200 based on the location information including an altitude according to the altitude value detected in the measurement point.

The electrode array determination module 604 may recognize the electrode array (for example, the location, direction, polarity, and electrode channel arrangement of each electrode) of the plurality of electrodes formed on at least one surface of the electronic device 200 according to the recognized location and attitude of the electronic device 200.

The electrode array determination module 604 may compare the electrode array of the plurality of electrodes according to the location and the attitude of the electronic device 200 recognized by the measurement location recognition module 602 with a preset electrode array of the plurality of electrodes, and determine whether the recognized electrode array is changed from the preset electrode array.

When there is a change in the location, direction, polarity, and electrode channel of at least one of the plurality of electrodes, the electrode array determination module 604 may determine that the recognized electrode array is changed.

When the electrode array determination module 604 determines that the recognized electrode array is changed, the switch control module 608 may control the switch unit 230 to make the recognized electrode array correspond to the preset electrode array. For example, the switch control module 608 may switch the switch unit 230 including a plurality of switches (or one switch including at least one input port and at least one output port) corresponding to the plurality of electrodes, respectively, and make a control to connect the preset electrode array to the biometric information measurement unit 220.

In the reference direction and the reference angle of the electronic device 200, the polarity of each electrode may be preset according to the location and the direction of each electrode. For example, it is assumed that the polarity of the left electrode A is set as (−) and the polarity of the right electrode B is set (+) in the reference direction and the reference angle of the electronic device 200. When the electronic device 200 has a change from the reference direction and the reference angle in the measurement point, the electrode array of the plurality of electrodes, that is, the location, direction, polarity, and electrode channel arrangement of each electrode may be changed according to the location and the attitude of the changed electronic device 200.

The switch control module 608 may compare the changed electrode array with a preset electrode array and control the switch unit 230 such that the changed electrode array corresponds to the preset electrode array. For example, when left and right directions of the left electrode A and the right electrode B are exchanged, the switch control module 608 may switch a switch corresponding to the corresponding electrode A to connection the left electrode A having the (+) polarity changed from the (−) polarity preset to the left electrode A to the biometric information measurement unit 220 and switch a switch corresponding to the corresponding electrode B to connect the right electrode B having the (−) polarity changed from the (+) polarity preset to the right electrode B to the biometric information measurement unit 220. Accordingly, the user or examinee can detect accurate biometric information (for example, biometric signal) regardless of the change in the location and the attitude of the electronic device 200.

The biometric information analysis module 610 may analyze the biometric information detected by the biometric information measurement unit 220 through the electrode array of the plurality of electrodes controlled by the switch control module 608. According to an embodiment of the present disclosure, the biometric information analysis module 610 may analyze the biometric information, that is, the biometric signal detected by the biometric information measurement unit 220. For example, the biometric information analysis module 610 may analyze biometric indexes, such as a heartrate, a heart period, a standard deviation of the heart period, a pulse, a number of arrhythmia occurrences, an impedance blood volume, and a stress index, from a parameter in a time domain of the detected biometric signal.

Meanwhile, the controller 280 may further include a biometric information conversion module 606 that converts the biometric information detected through the changed electrode array to correspond to the biometric information detected through the preset electrode array instead of the switch control module 608.

When there is the change in the electrode array of the plurality of electrodes recognized according to the location and the attitude of the electronic device 200 recognized in the measurement point, the biometric information conversion module 606 may convert and output the biometric signal detected through the recognized electrode array without controlling the recognized electrode array through the switch control module 608. For example, when it is determined that the recognized electrode array is changed, the biometric information conversion module 606 may convert the detected biometric signal to compensate for a difference between the recognized electrode array and the preset electrode array.

Referring to FIG. 7, the measurement location recognition module 602 of the controller 280 may determine whether a location recognition setting time (for example, 3 seconds) elapses in operation 702. When the location recognition setting time elapses, the measurement location recognition module 602 may detect a plurality of pieces of location information through the complex location sensor unit 210 at the location (measurement point) of the corresponding electronic device 200 in operation 704. When the location recognition setting time does not elapse in operation 702, the measurement location recognition module 602 returns to operation 702 and repeats the following operations.

The measurement location recognition module 602 of the controller 280 may recognize the location and the attitude of the electronic device 200 based on the plurality of pieces of detected location information, and recognize the electrode array of the plurality of electrodes in the measurement point according to the recognized location and attitude in operation 706. Thereafter, the electrode array determination module 604 may determine whether the recognized electrode array is changed from the preset electrode array in operation 708.

When the recognized electrode array is changed in operation 708, the switch control module 608 of the controller 280 may control a plurality of switches to make the recognized electrode array correspond to the preset electrode array and connect to the biometric information measurement unit 220 in operation 710. Meanwhile, when the recognized electrode array has no change in operation 708, the controller 280 proceeds to operation 712.

The biometric information analysis module 610 of the controller 280 may detect, in operation 712, biometric information from the biometric information measurement unit 220 for a measurement setting time through the electrode array controlled in operation 710, and analyze health state information based on the detected biometric information in operation 714. For example, the biometric information may include various biometric signals, such as an ECG signal, an EEG signal, an EOG signal, an EGG signal, and an EMG signal. Further, the health state information may include various biometric indexes, such as a heartrate, a heart period, a standard deviation of the heart period, a pulse, arrhythmia, an impedance blood volume, and a stress index, from a parameter in a time domain of the detected biometric signal.

The controller 280 may output a result (for example, a biometric index related to the detected biometric signal) analyzed by the biometric information analysis module 610 on the screen of the display unit 260 in operation 716.

Thereafter, the controller 280 may determine whether a re-measuring signal for measuring the biometric information again is input in operation 718. When the re-measuring signal is input, the controller 280 may return to operation 702 and repeat the following operations. When a re-measuring end signal is input in operation 718, the controller 280 may end the measurement of the biometric information.

In FIG. 8, a method of measuring biometric information through biometric information conversion is described according to various embodiments of the present disclosure.

Referring to FIG. 8, the controller 280 detects biometric information through the biometric information measurement unit 220 for a measurement setting time in operation 802.

The controller 280 recognizes a point where the biometric information is detected as a measurement point and detects a plurality of pieces of location information through the complex location sensor unit 210 in the measurement point in operation 804. For example, the plurality of pieces of location information may include an acceleration value, a geomagnetic value, and an altitude value.

The measurement location recognition module 602 of the controller 280 may recognize the location and the attitude of the electronic device 200 based on the plurality of pieces of detected location information, and recognize the electrode array of the plurality of electrodes in the measurement point according to the recognized location and attitude in operation 806. Thereafter, the electrode array determination module 604 may determine whether the recognized electrode array is changed from the preset electrode array in operation 808.

When the recognized electrode array has the change in operation 808, the biometric information conversion module 606 of the controller 280 may convert the recognized electrode array to compensate for a difference between the recognized electrode array and the preset electrode array in operation 810. For example, when preset electrode polarities are exchanged according to left and right directions of the electrodes, the biometric information (for example, biometric signal) detected through the recognized electrode array may be output as illustrated in FIG. 9A. In this case, the biometric information conversion module 606 may multiply the biometric signal (see FIG. 9A) detected through the electrode array having the exchanged electrode polarities by the error, that is, −1 as the compensation for the polarity reversal according to the left and right directions and thus convert the biometric signal of FIG. 9A into a normal biometric signal which is vertically reversed as illustrated in FIG. 9B. Meanwhile, when the recognized electrode array has no change in operation 808, the controller 280 proceeds to operation 812.

In operation 812, the biometric information analysis module 610 of the controller 280 may analyze the health state information based on the biometric information converted in operation 810 or detected in operation 802.

Thereafter, the controller 280 may determine whether a re-measuring signal for measuring the biometric information again is input in operation 816. When the re-measuring signal is input, the controller 280 may return to operation 802 and repeat the following operations.

The electronic device 1200 according to various embodiments of the present disclosure may include a complex location sensor unit 1210, an auxiliary sensor unit 1220 a biometric information measurement unit 1230, a switch unit 1240, and a controller 1290. Further, the electronic device 1200 may further include a storage unit 1250, an input unit 1260, a display unit 1270, and a communication unit 1280.

The complex location sensor unit 1210 may detect a plurality of pieces of location information (or a plurality of pieces of sensor information for calculating one piece of position (and/or location) information) in measurement points. The complex location sensor unit 1210 may include a plurality of location-based sensors and may detect each of the plurality of pieces of location information on the measurement point from the plurality of location-based sensors. According to an embodiment of the present disclosure, the plurality of pieces of location information may include an acceleration value, a geomagnetic value, and an altitude value. Further, the plurality of pieces of location information may include location-based detection values detected from all the location-based sensors, such as a gyro detection value, an angular speed detection value, and a motion detection value, but are not limited thereto. The controller 1290 may recognize a location and attitude of the electronic device 1200 in the measurement point based on the plurality of pieces of location information detected by the complex location sensor unit 1210 and determine an electrode array of a plurality of electrodes according to the recognized location and attitude of the electronic device 1200.

The body resistance measurement module 1231 may detect a size of the body resistance according to an amount of body fat of a measurement part which the examinee desires to measure. For example, the body resistance measurement module 1231 may detect two types of body resistance (for example, bio impedance and electrodermal activity (EDA) according to a measurement method.

The body resistance measurement module 1231 may detect an impedance value calculated by applying the alternate current passing through the measurement point through two electrodes which contact the measurement point and measuring a voltage at a time when the alternate current passes through the measurement point through two other electrodes which contact the measurement point. The impedance value may have different impedance standard ranges according to the measurement part and the measurement pose of the examinee.

For example, the controller 1290 may set a first measurement pose as the reference measurement pose, and detect biometric information of the examinee from the biometric information measurement unit 1230 connected through a plurality of electrodes having a preset electrode array (see FIG. 16B) according to the first measurement pose and set the detected biometric information as reference biometric information on the first measurement pose.

In operation 2204, the controller 1290 may calculate measurement part-specific biometric information according to a ratio of the preset measurement part by using the set reference biometric information. For example, since the detected reference biometric information corresponds to impedance of RA-TR-RL, the controller 1290 may calculate each impedance of the arm, TR, and leg by using the detected impedance according to body fat percentages of the arm, TR, and leg. It is assumed that the left and RAs have the same value and the left and RLs have the same value. For example, when the detected reference biometric information, that is, a reference impedance value is 510Ω and impedance ratios according to preset body fat percentages of the arm, TR, and leg are 30:1:20, reference impedance of the arm may be calculated as about 300Ω, reference impedance of the TR may be calculated as about 10Ω, and reference impedance of the leg may be calculated as about 200Ω.

The controller 1290 may calculate biometric information (for example, impedance) according to each of the plurality of preset measurement poses by combining the pieces of calculated biometric information according to each measurement part in operation 2206. For example, in a case of the first measurement pose, the impedance detected in operation 2202 may be reference impedance of the first measurement pose. Since the third measurement pose corresponds to the LA-RA in a state where the user stretches the arms, an impedance value corresponding to the third measurement pose may be calculated using the calculated arm reference impedance. Since the second measurement pose corresponds to the LA-RA in a state where the user bends the arms, an impedance value corresponding to the second measurement pose may be calculated using the calculated arm reference impedance and a proximity value according to a degree of the bent arms. Since the fourth measurement pose corresponds to the LA-RA in a state where the user pinches a plurality of electrodes with fingers, an impedance value corresponding to the fourth measurement pose may be calculated using the calculated arm reference impedance and a strain gage value according to a degree of pressing corresponding electrodes with fingers.

The controller 1290 may set the plurality of pieces of calculated measurement pose-specific biometric information as measurement pose-specific reference biometric information in operation 2208. For example, the controller 1290 may set each of the impedance values corresponding to the first to fourth measurement poses calculated in operation 2206 as a reference impedance value of each measurement pose.

The measurement pose-specific reference biometric information set as described above may correct the measurement pose determined in operation 2108 of FIG. 21. Through the measurement pose correction, it is possible to more precisely determine the measurement pose and detect biometric information of the examinee. Accordingly, the user can detect accurate biometric information in various measurement poses.
