Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.

Hereinafter, an EEG generating apparatus according to an embodiment of the present invention will be described in detail with reference to FIG. 1. 1 is a block diagram of an EEG generator according to an embodiment of the present invention.

As shown in FIG. 1, the EEG generator of the present invention includes a mode input unit 110, an EEG measurement control unit 120, an EEG generation unit 130, a near infrared ray generation unit 140, and an output unit 150. Is done.

The mode input unit 110 receives a use mode for each situation to be used by the user. The use mode includes at least one of an exercise mode, a learning mode, and a sleep mode. In the embodiment of the present invention, a switch for each mode is individually provided for mode selection, and the corresponding use mode is distinguished through an on / off state of the switch, but is not limited thereto.

The EEG measurement controller 120 measures the EEG of the user, and compares the frequency band range between the measured EEG and the normal EEG corresponding to the use mode, and generates a control signal.

Hereinafter, the EEG measurement controller will be described in detail with reference to FIG. 2. 2 is a block diagram of an EEG measurement control unit of the EEG generator according to an embodiment of the present invention.

As shown in FIG. 2, the EEG measurement unit 120 includes an EEG reception module 121, an amplification module 122, a filter module 123, an AD conversion module 124, a control module 125, and a storage module ( 126). The EEG module 121 attaches a plurality of electrodes to a user's scalp and receives the user's EEG through the electrodes. For example, a ground electrode of the plurality of electrodes is disposed at the center of the user's scalp, and the right brain electrode and the left brain electrode are attached to the user's scalp in the same number to receive the brain wave of the user. At this time, the received EEG receives the EEG for the frontal lobe of the user or the EEG for the area excluding the frontal lobe by the user's selection.

The amplification module 122 has an amplifier therein, and amplifies the brain waves of several tens μV to several tens of mV received by the EEG receiving module 121 to 3 to 5V through the amplifier to facilitate the received EEG analysis. do.

The filter module 123 includes a plurality of analog filters to filter various noises included in the brain waves amplified by the amplification module 122. In this case, the filter is composed of a high pass filter, a band pass filter, a band stop filter, and a low pass filter. The high pass filter primarily removes noise caused by DC voltage, respiration, body movement, eye blink, and the like, and the band pass filter filters brain waves having a frequency band range to be measured. The band blocking filter removes noise due to power supply of 50 Hz or 60 Hz, and the low pass filter prevents distortion by limiting EEG bands and prevents distortion occurring during EEG recovery.

The AD conversion module 124 digitizes the EEG in an analog state having a frequency band measured by the filter module 123.

The control module 125 has a frequency band range of the measured EEG digitized by the AD conversion module 124 previously stored in the storage module 126, and the normal EEG corresponding to the use mode previously input by the mode input unit 110. Compare to the frequency band range of. At this time, when the control module 125 determines that the frequency band range of the measured EEG is not included in the frequency band range of the normal EEG, the control module 125 generates a control signal for generating the normal EEG corresponding to the usage mode. At this time, the control signal includes a normal EEG generation signal for generating a normal EEG corresponding to the use mode and a near infrared generation signal for generating a near infrared ray. In addition, the control module 125 controls to output a voice signal indicating the mental state and the body state of the user previously stored in the storage module 126 through the output unit 150.

For example, when the use mode input through the switch in the mode input unit 110 is an exercise mode, a learning mode, or an operation mode, an egg to generate an alpha wave having a frequency band of 8 to 13 Hz. When the wave generation signal and the use mode is the sleep mode, at least one of the theta wave generation signal for generating a theta wave (theta wave) having a frequency band range of 4 to 7Hz.

The storage module 126 pre-stores normal EEG information indicating a frequency band range of the normal EEG corresponding to the usage mode input through the mode input unit 110. The normal EEG information is alpha wave related information having a frequency band range of 8 to 13 Hz when the use mode is an exercise mode, a learning mode or a driving mode, and a frequency band range of 4 to 7 Hz when the use mode is a sleep mode. Theta wave related information having a.

In addition, the storage module 126 stores a psychological state and a physical state of the user according to the measured brain waves measured by the user and a warning message according to the measured brain waves in the form of a voice signal. For example, when the user enjoys the exercise of golf, archery, shooting, etc. while the use mode input to the mode input unit 110 is the exercise mode, the brain wave measurement control unit 120 measures the user's measured brain wave If the beta wave having a frequency band range of 14 to 21 Hz, the current psychological state of the user is worried, anxious, irritable state, the body state can be seen that the muscles are rigid. Based on the user's psychological state and body condition, the current user's psychological state and body state are stored as a voice signal, along with a warning message "Relieve tension" is also stored as a voice signal.

Returning to FIG. 1 again, the EEG generator 130 generates a normal EEG corresponding to the usage mode in response to the control signal generated from the EEG measurement controller 120.

For example, when the use mode is an exercise mode, a learning mode, or a driving mode, the EEG measurement control unit 120 generates a control signal including an alpha wave generation signal, and responds to the control signal at 8 to 13 Hz. Generate an alpha wave having a frequency band range. Alternatively, when the use mode is the sleep mode, the EEG measurement control unit 120 generates a control signal including the theta wave generation signal, and theta wave having a frequency band range of 4 to 7 Hz in response to the control signal. Occurs.

As the control signal generated by the EEG measurement control unit 120 includes a near infrared generation signal, the near infrared generation unit 140 includes an infrared diode therein when the control signal is applied, and the infrared diode is turned on. turn-on) to generate near-infrared rays.

The output unit 150 transmits the normal EEG corresponding to the use mode generated by the EEG generator 130 and the NIR generated by the NIR 140 to the user. The output unit 150 transmits the normal EEG generated in response to the use mode to a portion corresponding to the use mode of the brain region of the user.

For example, when the learning mode is input to the use mode, the output unit 150 transmits an alpha wave to the front lobe portion of the brain region of the user. At this time, the frontal lobe part is a part involved in human learning and cognitive activity, and as the alpha wave is received, a higher learning effect can be expected. Alternatively, when the driving mode is input to the use mode, the output unit 150 transmits an alpha wave to a parietal lobe portion of the brain region of the user. At this time, the parietal lobe part is a part involved in physical activity of a person, so that the user is required to drive in a more stable state agile physical activity as the alpha wave is received. Alternatively, when the exercise mode is input to the use mode, the output unit 150 transmits an alpha wave to the left parietal lobe portion of the brain region of the user. Since the left parietal lobe is a part involved in the physical activity of a person like the parietal lobe, the alpha wave is transmitted so that the user can exercise in a comfortable state without a mistake due to tension. Alternatively, when the sleep mode is input to the use mode, the output unit 150 transmits theta wave to the central fissure portion of the brain region of the user. Since the central fissure is located at the boundary between the frontal lobe and the parietal lobe and associated with the thalamus, the central fissure induces a smooth sleep state of the user.

The output unit may transmit a near infrared ray generated by the near infrared ray generating unit to a user. For example, the near-infrared ray in the range of 800 to 1300 nm may be irradiated to the user until the normal EEG corresponding to the use mode is measured by the EEG measurement control unit 120 for 30 seconds at an irradiation intensity of 50 mn and watts / cm.

As the near-infrared ray is irradiated to the user, the brain of the user is activated, the nerve activity becomes more active, the amount of oxygen supplied to the brain region is increased, the brain material is secreted, and memory activation occurs.

 In addition, the output unit 150 has a voice including a psychological state and a physical state of the user and a warning message based on the measured brain waves measured by the EEG measurement controller 120 pre-stored in the storage module 126. Deliver the signal to the user. At this time, the voice signal may be transmitted to the user through a speaker or earphone.

For example, when the user enjoys the exercise of golf, archery, shooting, etc. while the use mode input to the mode input unit 110 is the exercise mode, the brain wave measurement control unit 120 measures the user's measured brain wave If the beta wave having a frequency band range of 14 to 21 Hz, the current psychological state of the user is worried, anxious, irritable state, the body state can be seen that the muscles are rigid. On the basis of the user's psychological state and physical condition, the current user's psychological state and body state is stored as a voice signal, along with a warning message "Relieve tension" is also a voice signal to the storage module 126. Stored. In this manner, the voice signal “relax tension”, which is a voice signal about the mental state and the physical state of the user, is transmitted to the user.

Such an EEG generator may be implemented in a headband, a headband, a hat, or a removable product that a user may wear on the head, and may transmit normal EEG, NIR, and voice signals directly to the user.

As a result, the EEG generating apparatus and method of the present invention generates the normal EEG so as to directly generate the normal EEG according to each situation input by the user in the use mode, thereby directly inducing the generation of the EEG. can do.

Hereinafter, a method for generating an EEG according to another embodiment of the present invention will be described with reference to FIG. 3. 3 is a flowchart illustrating a method for generating an EEG according to another embodiment of the present invention.

As shown in FIG. 3, the user receives a usage mode according to a situation to be used by the user (S210). At this time, the use mode received from the user is a golf mode, an exercise mode used for exercise requiring high concentration of archery, shooting, etc., a learning mode used for students studying, driving used when running on a highway or straight road. Mode, at least one of the sleep mode used when you want to get a good night's sleep.

Thereafter, the brain wave of the user who has entered the usage mode is measured (S220). By measuring the same number of electrodes on both sides of the user's scalp EEG for the left and right brain of the user is measured.

By comparing the measured EEG of the user measured in this way with the normal EEG corresponding to the use mode, it is checked whether the frequency band range of the measured EEG is included in the frequency band range of the normal EEG corresponding to the use mode (S230).

For example, when the user selects and inputs the learning mode as the use mode, the frequency band of the normal EEG corresponding to this is 8 to 13 Hz, which corresponds to an alpha wave among the types of EEG. In this case, when the measured brain waves measured from the scalp of the user is a beta wave having a frequency of 14 to 21 Hz, it can be seen that the frequency band range of the measured brain waves is not included in the frequency band range of the normal brain waves.

As such, when the frequency band range of the measured EEG is not included in the frequency band range of the normal EEG corresponding to the usage mode, the EEG generation signal and the near-infrared generation signal for generating the normal EEG corresponding to the usage mode are included. A control signal is generated (S240). Accordingly, referring to the example in which the learning mode is input to the use mode, an alpha wave generation signal for generating an alpha wave having a frequency range of 8 to 13 Hz, which is a normal brain wave corresponding to the learning mode input as the use mode, is generated. do. The alpha wave generation signal is generated equally even when the exercise mode or the driving mode is input as the use mode.

In contrast, when the sleep mode is input as the usage mode, theta wave generation signal for generating theta waves having a frequency band of 4 to 7 Hz, which is a normal brain wave corresponding to the usage mode, is generated.

Accordingly, in response to the control signal including each normal EEG signal, the normal EEG is generated (S250). For example, when the use mode is an exercise mode, a learning mode, or a driving mode, an alpha wave is generated in response to a control signal including an alpha wave generation signal, and when the use mode is a sleep mode, the alpha wave generation signal includes a theta wave generation signal. Theta wave is generated in response to the control signal.

In addition, the near infrared ray is generated in response to the control signal including the near infrared ray generation signal (S260). In response to the control signal including the near infrared generation signal, an infrared diode is turned on and thus near infrared is generated from the infrared diode.

The normal EEG and NIR generated as described above are output to the user (S270). Normal brain waves and near infrared rays corresponding to the selected mode of use are directly transmitted to the user through a headband, a headband, a hat or a product detachable to the user's scalp. In addition, based on the measured brain waves of the user and the use mode input from the user, the user's psychological state and physical state and a warning message based on the current user can be transmitted to the user through a voice signal.

For example, the frequency band range other than the alpha wave of the frequency band range of 8 to 13 Hz, wherein the usage mode is the exercise mode or the learning mode, and the measured brain wave of the user is the normal brain wave corresponding to the exercise mode or the learning mode, is 14 to 14. In the case of the beta wave of 21 Hz, it can be seen that the psychological state of the user is in an excited state and the physical state is also in a tense state, and the state of the user is not suitable for the exercise mode or the learning mode input by the user.

Therefore, it is possible to determine the pre-stored psychological state and physical state of the user, and the use mode and suitability according to the pre-stored user, not only to induce the normal EEG generation from the user by transferring the normal EEG to the user, but also to the user. The voice signal can directly transmit a warning message about the current state of mind and body.

Since the psychological state and the physical state of the user described above do not correspond to the current user's mode of use, the user receives his / her own state by directly transmitting a warning message such as "Relieve tension" to the user through a voice signal. Can be accurately aware of

In addition, if the user mode is used as a driving mode, and the measured brain wave of the user is theta wave in the frequency band range of 4 to 7 Hz, the psychological state of the current user is very calm and the body state can be understood as a dozing state. have. Accordingly, an alpha wave of 8 to 13 Hz, which is a frequency band range suitable for the driving mode, is generated and transmitted to the user, thereby inducing the user to generate an alpha wave. In addition, by sending a warning message such as "Driving. Do not sleep" to the user to prevent the user from drowsy driving to prevent the occurrence of traffic accidents.

Alternatively, when the user uses the user mode as a sleep mode, and the measured brain wave of the user is a beta wave in the frequency band range of 14 to 21 Hz, the user's psychological state is unstable, and the physical state can also be understood to be nervous. Accordingly, theta wave of 4 to 7 Hz, which is a frequency band range suitable for the sleep mode, is generated and transmitted to the user, thereby inducing the user to generate theta wave. In addition, the user may be alerted to the current state of the user by delivering a warning message such as "relax tension and get a good night's sleep".

The normal EEG corresponding to the usage mode is delivered to the user, not only to induce the user to generate a normal EEG suitable for the usage mode, but also the near infrared ray generated in response to a control signal including the NIR signal. It is delivered directly to the user, so that the user generates a normal EEG corresponding to the mode of use.

For example, when the learning mode is input to the use mode, an alpha wave is transmitted to the front lobe portion of the brain region of the user. At this time, the frontal lobe part is a part involved in human learning and cognitive activity, and as the alpha wave is received, a higher learning effect can be expected. Alternatively, when the driving mode is input to the use mode, the alpha wave is transmitted to the parietal lobe portion of the brain region of the user. At this time, the parietal lobe part is a part involved in physical activity of a person, so that the user is required to drive in a more stable state agile physical activity as the alpha wave is received. Alternatively, when the exercise mode is input to the use mode, an alpha wave is transmitted to a left parietal lobe portion of the brain region of the user. Since the left parietal lobe is a part involved in the physical activity of a person like the parietal lobe, the alpha wave is transmitted so that the user can exercise in a comfortable state without a mistake due to tension. Alternatively, when the sleep mode is input to the use mode, theta wave is transmitted to the central fissure portion of the brain region of the user. Since the central fissure is located at the boundary between the frontal lobe and the parietal lobe and associated with the thalamus, the central fissure induces a smooth sleep state of the user.

Normal brain waves including these alpha waves or theta waves are delivered to the user as well as near infrared rays. For example, the output unit 150 transmits the near-infrared generated from the near-infrared generator to the user. For example, the near-infrared in the range of 800 nm to 1300 nm is irradiated at 50 mu. Watts / cm for 30 seconds, and the EEG measurement control unit The user may be irradiated until the normal brain wave is measured at 120.

As the near-infrared ray is irradiated to the user, the brain of the user is activated, the nerve activity becomes more active, the amount of oxygen supplied to the brain region is increased, and the brain material is secreted to activate memory.

Accordingly, the EEG generator and method of the present invention induces the user to generate an appropriate EEG according to each situation, so that the user can perform the action smoothly in the situation.

In other words, the EEG generating apparatus of the present invention generates a high-frequency effect when the user generates an alpha wave during exercise requiring concentration, such as golf, archery, and shooting, and induces the user to generate the alpha wave, resulting in a high exercise effect. You can expect

In addition, the EEG generator according to the present invention generates an alpha wave when the driver feels drowsiness when driving on a straight road such as a highway, and transmits it to the driver, thereby preventing the driver from drowsy driving and causing traffic accident rate caused by drowsy driving. It can be expected to reduce the effect.

In addition, the EEG generating apparatus of the present invention generates an alpha wave to the students who lack concentration or psychological stability and transmit it to the student to improve the concentration, psychological stability can be expected, higher learning achievement effect is expected Can be.

In addition, the EEG generating apparatus of the present invention can be expected to produce an insomnia patient suffering from sleep disorders and the effect of having three sleeps and delivering it to the insomnia patient to take a good night's sleep.

In addition, the EEG generating apparatus of the present invention measures the user's brain waves, and delivers the user's psychological state and the warning message according to the psychological state directly to the user, so that the user is aware of the current state There is.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited thereto, and various modifications and changes can be made within the scope of the technical idea of the present invention. Do.
