The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0042] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate.

[0067] According to one embodiment, the shape memory wire (3112) may serve as a support to support the ear hook (310) to maintain a specific shape overall. The shape memory wire (3112) may be formed so that the ear hook (310) can wrap around the back of the user's ear when the user wears the wearable electronic device (300). The shape memory wire (3112) may be composed of a shape memory material.

[0068] According to one embodiment, the cover portion (3113) may be arranged to cover the wire portion (3111) and the shape memory wire (3112). The cover portion (3113) may be arranged to wrap around the periphery of the shape memory wire (3112) so that the wire portion (3111) and the shape memory wire (3112) are not visible from the outside. The cover portion (3113) may include an elastomer such as silicone.

[0069] According to one embodiment, the ear hook (310) may include a temporal electrode (3114). The temporal electrode (3114) may include a conductive material such as metal, conductive fabric, conductive rubber, or polymer.

[0070] In one embodiment, the temporal electrode (3114) may be electrically connected to the shape memory wire (3112). The temporal electrode (3114) may be positioned to extend from the shape memory wire (3112). For example, the temporal electrode (3114) may be positioned to extend in a direction approximately perpendicular to the extension direction of the shape memory wire (3112).

[0071] In one embodiment, the temporal electrode (3114) may be positioned to penetrate the cover portion (3113). The temporal electrode (3114) may be positioned such that a portion thereof is exposed to the outside of the cover portion (3113). The temporal electrode (3114) may be positioned such that a free end thereof, which is distant from the shape memory wire (3112), is at least partially exposed to the outside of the cover portion (3113).

[0072] According to one embodiment, the ear hooks (310) may be plural. The plurality of ear hooks (310) may include a first ear hook (311) and a second ear hook (312). The first ear hook (311) and the second ear hook (312) may be arranged to be mirror-symmetrical on the left and right sides with respect to the center. The configuration of the first ear hook (311) and the configuration of the second ear hook (312) may be substantially the same. The first ear hook (311) and the second ear hook (312) may be respectively placed over the left and right ears when the user wears the wearable electronic device (300). The first ear hook (311) and the second ear hook (312) may be respectively positioned to wrap around the back of the left ear and the back of the right ear when the user wears the wearable electronic device (300).

[0073] According to one embodiment, there may be a plurality of temporal electrodes (3114). The plurality of temporal electrodes (3114) may include a first temporal electrode (3114a) and a second temporal electrode (3114b). The first temporal electrode (3114a) and the second temporal electrode (3114b) may be arranged so as to be mirror-symmetrical left and right with respect to the center.

[0074] According to one embodiment, the first ear hook (311) may include a first temporal electrode (3114a). According to one embodiment, the second ear hook (312) may include a second temporal electrode (3114b).

[0075] According to one embodiment, the first temporal electrode (3114a) may be electrically connected to the shape memory wire (3112) of the first ear hook (311). According to one embodiment, the second temporal electrode (3114b) may be electrically connected to the shape memory wire of the second ear hook (312).

[0076] According to one embodiment, the first temporal electrode (3114a) and the second temporal electrode (3114b) may be positioned to face inward. For example, the first temporal electrode (3114a) and the second temporal electrode (3114b) may be positioned to face each other. For example, the first temporal electrode (3114a) and the second temporal electrode (3114b) may be positioned to face each other. For example, the first temporal electrode (3114a) and the second temporal electrode (3114b) may be positioned such that an imaginary first extension line extending in the direction of the first temporal electrode (3114a) and an imaginary second extension line extending in the direction of the second temporal electrode (3114b) intersect each other to form an acute angle. Since the first temporal electrode (3114a) and the second temporal electrode (3114b) are positioned to face inward, when a user wears the wearable electronic device (300), the first temporal electrode (3114a) and the second temporal electrode (3114b) can come into contact with the user's left temporal region (520) and right temporal region (520), respectively. The first temporal electrode (3114a) and the second temporal electrode (3114b) that come into contact with the temporal region (520) can detect brain wave signals generated in the user's temporal lobe.

[0077] As the number of electrodes for brain wave measurement increases, the number of wires for connecting the electrodes and the processor (361) may also increase. If the number of wires increases, the size and weight of the wearable electronic device (300) may increase, which may make it uncomfortable to use. In the present disclosure, by using the existing shape memory wire (3112) without adding a new wire when the temporal electrode (3114) is added, the structure of the product may be simplified and the weight may be reduced. That is, even when two electrodes, the first temporal electrode (3114a) and the second temporal electrode (3114b), are added, the structure of the wearable electronic device (300) may be simplified by using the existing shape memory wires (3112) on the left and right sides as an electrical connection means without adding a corresponding wire.

[0104] The embodiment of FIG. 7 can be optionally combined with at least one of the embodiments of FIGS. 1 to 6 and FIGS. 8a to 13.

[0105] Among the configurations of FIG. 7, the same reference numbers are used for configurations that are substantially the same or similar to the configurations described in FIGS. 3 to 6.

[0106] Referring to FIG. 7, a wearable electronic device (300) according to one embodiment may include at least one of a first temporal electrode (3114a), a second temporal electrode (3114b), a first transition electrode (351), a second transition electrode (352), at least one processor (361), and a memory (362).

[0107] According to one embodiment, the memory (362) (e.g., the memory (130) of FIG. 1) may store data supporting various operations of the wearable electronic device (300). The memory (362) may store, for example, a plurality of application programs (or applications) used in the wearable electronic device (300), data for the operation of the wearable electronic device (300), and commands. At least some of these application programs may be downloaded from an external server via wireless communication. In addition, at least some of these application programs may be stored in the memory (362) from the time of shipment for the basic functions of the wearable electronic device (300).

[0108] According to one embodiment, the memory (362) can store various data that can be used to control the operation of each component of the wearable electronic device (300). The memory (362) can include, for example, at least one storage medium that stores a plurality of application programs used in the wearable electronic device (300), data for controlling the operation of the wearable electronic device (300), and commands. The commands stored in the memory (362), when executed by at least one processor (361), can cause the wearable electronic device (300) to perform at least one operation (e.g., at least one of the operations described in FIGS. 7 to 12).

[0109] According to one embodiment, the memory (362) can store at least one program for processing and controlling the processor (361), and can store input and / or output data. The memory (362) can also store at least one artificial intelligence model. The memory (362) can include at least one of a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (e.g., a secure digital (SD) or extreme digital (XD) memory), a random access memory (RAM), a static random access memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, and an optical disk. According to one example, a web storage or a cloud server that performs a storage function on the Internet may be operated by the wearable electronic device (300).

[0110] According to one embodiment, at least one processor (361) can receive an electrical signal detected by the first temporal electrode (3114a), the second temporal electrode (3114b), the first transition electrode (351), or the second transition electrode (352). The instructions of the memory (362), when individually or collectively executed by the at least one processor (361), can cause the wearable electronic device (300) to receive an electrical signal detected by the first temporal electrode (3114a), the second temporal electrode (3114b), the first transition electrode (351), or the second transition electrode (352).

[0111] According to one embodiment, at least one processor (361) can select a signal detected by two of the first temporal electrode (3114a), the second temporal electrode (3114b), the first prefrontal electrode (351), or the second prefrontal electrode (352) to measure an EEG signal. The instructions of the memory (362), when individually or collectively executed by the at least one processor (361), can cause the wearable electronic device (300) to select a signal detected by two of the first temporal electrode (3114a), the second temporal electrode (3114b), the first prefrontal electrode (351), or the second prefrontal electrode (352) to measure an EEG signal.

[0112] According to one embodiment, at least one processor (361) may select an electrode that detects a relatively strong electrical signal of a brain wave as an active electrode, and may select an electrode that detects a relatively weak electrical signal of a brain wave as a reference electrode, and may measure a brain wave signal by using the difference between the active electrode and the reference electrode. When the instructions of the memory (362) are individually or collectively executed by at least one processor (361), they may cause the wearable electronic device (300) to select an electrode that detects a relatively strong electrical signal of a brain wave as an active electrode, and may select an electrode that detects a relatively weak electrical signal of a brain wave as a reference electrode, and may measure a brain wave signal by using the difference between the active electrode and the reference electrode.

[0113] For example, at least one processor (361) can select the first temporal electrode (3114a) or the second temporal electrode (3114b) as the active electrode. The first temporal electrode (3114a) and the second temporal electrode (3114b) can each detect electrical signals generated in the temporal lobe. The instructions of the memory (362), when individually or collectively executed by the at least one processor (361), can cause the wearable electronic device (300) to select the first temporal electrode (3114a) or the second temporal electrode (3114b) as the active electrode.

[0114] When electrodes are positioned in the external auditory canal to detect brain wave signals among wearable audio devices, the size of the brain wave signals may be small and noise may increase due to the thick skull bones formed in the external auditory canal. According to one embodiment, the wearable electronic device (300) can improve the accuracy of brain wave measurement by positioning the electrodes in the temporal region (e.g., the temporal region (520) of FIG. 5) so that brain wave signals can be received relatively strongly.

[0115] For example, at least one processor (361) may select the first transition electrode (351) or the second transition electrode (352) as a reference electrode. The first transition electrode (351) and the second transition electrode (351) may be located relatively far from the brain, so that the intensity of the brain wave signal detected may be small. The instructions of the memory (362), when individually or collectively executed by at least one processor (361), may cause the wearable electronic device (300) to select the first transition electrode (351) or the second transition electrode (352) as a reference electrode.

[0116] However, the present invention is not limited thereto, and at least one processor (361) may select one of the first temporal electrode (3114a) or the second temporal electrode (3114b) as a reference electrode. The instructions of the memory (362), when individually or collectively executed by the at least one processor (361), may cause the wearable electronic device (300) to select one of the first temporal electrode (3114a) or the second temporal electrode (3114b) as a reference electrode.

[0117] According to one embodiment, at least one processor (361) can measure brain wave signals using active electrodes and reference electrodes. The instructions of the memory (362), when individually or collectively executed by at least one processor (361), can cause the wearable electronic device (300) to measure brain wave signals using the active electrodes and the reference electrodes. For example, at least one processor (361) can calculate a frequency domain of brain wave signals generated in the user's brain. For example, at least one processor (361) can calculate a frequency domain of brain wave signals at set intervals. For example, at least one processor (361) can measure brain wave signals by randomly selecting one active electrode and one reference electrode to calculate the frequency domain of the brain wave signals. As the number of times the frequency domain of the brain wave signals is calculated increases, accuracy can increase.

[0118] According to one embodiment, at least one processor (361) can estimate or determine the mental state of the user based on the frequency domain of the measured brain waves. The instructions of the memory (362), when individually or collectively executed by at least one processor (361), can cause the wearable electronic device (300) to estimate or determine the mental state of the user based on the frequency domain of the measured brain waves. For example, at least one processor (361) can estimate the state of the user meditating, the user's concentration, the user's stress, etc. by quantifying them based on the frequency domain of the measured brain waves. The estimated value can be transmitted to the user's electronic device (e.g., the electronic device (104) of FIG. 1) through a communication module (e.g., the communication module (190) of FIG. 1). However, the present invention is not limited thereto, and at least one processor (361) can estimate or determine various brain states of the user by using the frequency domain of the measured brain waves.

[0119] According to one embodiment, at least one processor (361) may use the user's stress level or concentration score determined using brain waves to, if necessary, operate an audio module (e.g., audio module (390) of FIG. 3) to play music or sounds that stimulate the user's mood. The instructions of the memory (362), when individually or collectively executed by at least one processor (361), may cause the wearable electronic device (300) to use the user's stress level or concentration score determined using brain waves to, if necessary, operate the audio module (390) to play music or sounds that stimulate the user's mood.

For example, the temporal electrode (3114-1) may be formed so as not to protrude outwardly from the cover portion (3113).

[0126] Referring to FIG. 8B, according to one embodiment, the ear hook (310) may include a temporal electrode (3114-2) extending from a shape memory wire (3112). Here, the temporal electrode (3114-2) may be formed integrally with the shape memory wire (3112).

[0127] Referring to FIG. 8C, according to one embodiment, the ear hook (310) may include a temporal electrode (3114-3) coupled to a shape memory wire (3112). The temporal electrode (3114-3) may be a conductive material that is electrically connected to the shape memory wire (3112). For example, the temporal electrode (3114-3) may be coupled to the shape memory wire (3112) by solder. For example, the temporal electrode (3114-3) may be electrically connected by having a portion in contact with the shape memory wire (3112).

[0128] According to one embodiment, the temporal electrode (3114-3) may include a catch (3114a-3) extending toward the cover (3113). The catch (3114a-3) may be located within the cover (3113). According to one embodiment, the cover (3113) may include a catch (3113a) protruding from a surface into which the temporal electrode (3114-3) is inserted so as to face the temporal electrode (3114-3). The catch (3113a) may serve as a stopper to prevent the temporal electrode (3114-3) from being dislodged outside the cover (3113). For example, when the temporal electrode (3114-3) is electrically connected to the shape memory wire (3112) by contact, the catch (3113a) may be formed to fix the temporal electrode (3114-3) or to allow the temporal electrode (3114-3) to be in close contact with the shape memory wire (3112).

[0129] Although not shown, according to one embodiment, the temporal electrode (3114-3) can be fitted into a hole of the cover part (3113).

By fitting the temporal electrode (3114-3) into the cover part (3113), the temporal electrode (3114-3) and the shape memory wire (3112) can be brought into contact and electrically connected by the pressure that the cover part (3113) applies to the temporal electrode (3114-3).

[0130] According to one embodiment, the temporal electrode (3114-1, 3114-2, or 3114-3) of FIG. 8A, FIG. 8B, or FIG. 8C may comprise a conductive material such as a metal, conductive fabric, conductive rubber, or polymer.

[0131] FIG. 9 is an exemplary flowchart for explaining a method of operating a wearable electronic device according to one embodiment.

[0132] The embodiment of FIG. 9 can be optionally combined with at least one of the embodiments of FIGS. 1 to 8c and FIGS. 10a to 13.

[0133] Referring to FIG. 9, a wearable electronic device (e.g., the wearable electronic device (300) of FIG. 3) may perform an operation (910) of selecting two signals from among signals received from a first temporal electrode (e.g., the first temporal electrode (3114a) of FIG. 4), a second temporal electrode (e.g., the second temporal electrode (3114b) of FIG. 4), a first transition electrode (e.g., the first transition electrode (351) of FIG. 4), and a second transition electrode (e.g., the second transition electrode (352) of FIG. 4). For example, the wearable electronic device (300) may select two electrodes from among the first temporal electrode (3114a), the second temporal electrode (3114b), the first transition electrode (351), and the second transition electrode (352) to receive a detection signal.

[0134] In one embodiment, the wearable electronic device (300) may select either the first temporal electrode (3114a) or the second temporal electrode (3114b) as the active electrode. In one embodiment, the wearable electronic device (300) may select either the first transition electrode (351) or the second transition electrode (352) as the reference electrode.

[0135] However, the present invention is not limited thereto, and the wearable electronic device (300) may select any one of the four electrodes as an active electrode and any one of the remaining three electrodes as a reference electrode.

[0136] According to one embodiment, the wearable electronic device (300) can perform an operation (920) of measuring an EEG signal and calculating a frequency domain of the EEG signal using the selected signal. The wearable electronic device (300) can measure an EEG signal using the detection signal selected in operation 910.

[0137] The wearable electronic device (300) can measure brain wave signals using signals detected by each active electrode and reference electrode selected in operation 910. The wearable electronic device (300) can calculate the frequency domain of signals mainly output from brain waves using an FFT (Fast Fourier Transform) algorithm.

[0138] According to one embodiment, the wearable electronic device (300) can perform an operation (930) of estimating or determining the state of the user's brain based on the calculated frequency domain.

[0139] According to one embodiment, the wearable electronic device (300) can estimate or determine the state of the user's brain by using the frequency domain of brain waves and the magnitude of the corresponding signal. For example, if the user is meditating, the wearable electronic device (300) can estimate or determine the degree of entering the meditative state by quantifying it based on the frequency domain of the calculated brain waves. For example, the wearable electronic device (300) can estimate or determine the user's stress state by quantifying it based on the frequency domain of the calculated brain waves. For example, if the user is studying or working, the wearable electronic device (300) can estimate or determine the concentration by quantifying it based on the frequency domain of the calculated brain waves.

[0140] According to one embodiment, the wearable electronic device (300) can provide information about the estimated or determined brain state to the user. The wearable electronic device (300) can transmit the information about the estimated or determined brain state to the user's electronic device (e.g., the electronic device (104) of FIG. 1) using a communication module (e.g., the communication module (190) of FIG. 1).

[0141] According to one embodiment, the wearable electronic device (300) may operate an audio module (e.g., the audio module (390) of FIG. 3) based on the estimated or determined brain state. For example, if the wearable electronic device (300) determines that the user's stress level, as estimated or determined, has increased above a predetermined level, the wearable electronic device (300) may operate the audio module (390) to provide sound to alleviate the user's stress.

[0142] According to one embodiment, the wearable electronic device (300) can estimate or determine the state of the brain more accurately by repeatedly performing operations 910 and 920 at set intervals to increase the amount of data.

[0143] FIGS. 10A, 10B, 10C, and 10D are diagrams illustrating a process of measuring brain waves by selecting two electrodes in a wearable electronic device. FIG. 11 is a graph of a brain wave signal measured by merging at least two signals from FIGS. 10A, 10B, 10C, and 10D.

[0144] FIG. 10a, FIG. 10b, FIG. 10c, and FIG. 10d are exemplary drawings for explaining an operation of measuring brain waves using a first temporal electrode (3114a), a second temporal electrode (3114b), a first prefrontal electrode (351), and a second prefrontal electrode (352) in a wearable electronic device (300), and the scope of the present disclosure is not limited to what is illustrated.

[0145] As illustrated in FIG. 10A, the wearable electronic device (300) can measure brain wave signals using signals received from the first temporal electrode (3114a) and the second transition electrode (352). The wearable electronic device (300) can measure brain wave signals by selecting the first temporal electrode (3114a) as an active electrode and the second transition electrode (352) as a reference electrode.

[0146] As illustrated in FIG. 10b, the wearable electronic device (300) can measure brain wave signals using signals received from the first temporal electrode (3114a) and the first precuneus electrode (351). The wearable electronic device (300) can measure brain wave signals by selecting the first temporal electrode (3114a) as an active electrode and the first precuneus electrode (351) as a reference electrode.

[0147] As illustrated in FIG. 10c, the wearable electronic device (300) can measure brain wave signals using signals received from the second temporal electrode (3114b) and the first prefrontal electrode (351). The wearable electronic device (300) can measure brain wave signals by selecting the second temporal electrode (3114b) as an active electrode and the first prefrontal electrode (351) as a reference electrode.

[0148] As illustrated in FIG. 10d, the wearable electronic device (300) can measure brain wave signals using signals received from the second temporal electrode (3114b) and the second precuneus electrode (352). The wearable electronic device (300) can measure brain wave signals by selecting the second temporal electrode (3114b) as an active electrode and the second precuneus electrode (352) as a reference electrode.

[0149] In one embodiment, the further apart the temporal electrode (3114) and the precuneus electrode (350) are, the smaller the noise level measured. For example, the EEG signals measured in FIGS. 10A and 10C have smaller noise levels than the EEG signals measured in FIGS. 10B and 10D.

[0150] Fig. 11 is a graph showing a combined state of brain wave signals measured by the methods of Figs. 10a, 10b, 10c, and 10d, respectively. The wearable electronic device (300) can increase measurement accuracy as the electrode combinations capable of measuring brain wave signals become more diverse. When measuring brain wave signals, the wearable electronic device (300) can increase measurement accuracy by merging brain wave signals measured using various electrode combinations. However, the present invention is not limited thereto, and the wearable electronic device (300) can also merge brain wave signals measured using only two or more of the methods of Figs. 10a, 10b, 10c, and 10d. For example, the wearable electronic device (300) can measure brain wave signal values ​​obtained by merging brain wave signals measured using only the methods of Figs. 10a and 10c, which have relatively small noise values.

[0151] Figure 12 is a flowchart illustrating an operation for measuring brain waves when audio is output from a wearable electronic device.

[0152] The embodiment of FIG. 12 can be optionally combined with at least one of the embodiments of FIGS. 11 to 13.

[0153] FIG. 12 illustrates a method for a wearable electronic device (e.g., a wearable electronic device (300) of FIG. 3) to measure brain waves while sound is output from an audio module (e.g., an audio module (390) of FIG. 3 or an audio module (170) of FIG. 1).

[0154] Referring to FIG. 12, the wearable electronic device (300) can perform an operation (1210) of determining whether sound is being output from the audio module (390). If sound is not being output from the audio module (390), the wearable electronic device (300) can measure brain waves using the method of FIG. 9.

[0155] According to one embodiment, when sound is output from the audio module (390), the wearable electronic device (300) may perform an operation (1220) of receiving a detection signal from a first temporal electrode (e.g., the first temporal electrode (3114a) of FIG. 4) and a second temporal electrode (e.g., the second temporal electrode (3114b) of FIG. 4). When sound is output from the audio module (390), a signal detected by a transition electrode (350) adjacent to the audio module (390) may include a lot of noise. Therefore, the wearable electronic device (300) may measure brain waves using the first temporal electrode (3114a) and the second temporal electrode (3114b), not the transition electrode (350), while sound is output to the audio module (390).

[0156] According to one embodiment, the wearable electronic device (300) may perform an operation (1230) of measuring a first brain wave signal by selecting one of the first temporal electrode (3114a) and the second temporal electrode (3114b) as a reference electrode. For example, the wearable electronic device (300) may select the first temporal electrode (3114a) as a reference electrode. Accordingly, the wearable electronic device (300) may select the second temporal electrode (3114b) as an active electrode.

[0157] According to one embodiment, the wearable electronic device (300) may perform an operation (1240) of receiving a detection signal from a first temporal electrode (3114a) and a second temporal electrode (3114b). Operation 1240 may be substantially the same as operation 1220.

[0158] According to one embodiment, the wearable electronic device (300) may perform an operation (1250) of measuring a second brain wave signal by selecting another electrode among the first temporal electrode (3114a) and the second temporal electrode (3114b) as a reference electrode. For example, if the first temporal electrode (3114a) is selected as the reference electrode in operation 1230, the wearable electronic device (300) may select the second temporal electrode (3114b) as the reference electrode in operation 1250.

[0159] According to one embodiment, the wearable electronic device (300) can measure brain waves at set time intervals by alternately selecting the first temporal electrode (3114a) and the second temporal electrode (3114b) as reference electrodes.

[0160] According to one embodiment, the wearable electronic device (300) may perform operation (1260) of combining a first brain wave signal and a second brain wave signal to form a single EEG dataset. According to one embodiment, the wearable electronic device (300) may improve the accuracy of the EEG dataset by repeatedly performing operations 1220 to 1250.

[0161] In one embodiment, operations 1240 and 1250 may be omitted.
