Description

An EEG induction device and a method therefor}

The present invention relates to an apparatus and method for providing a sound source for inducing brain waves from reproduced content, and more specifically, from audio and/or video content including audio such as music or language (speech). The present invention relates to an apparatus and method for providing a signal having the same frequency and waveform as a corresponding brain wave as a signal for inducing an EEG suitable for a user who uses the content.

In general, the human brain is affected by external stimuli such as sight, hearing, and touch, and a phenomenon in the brain that tries to match the frequency of the stimulus transmitted from the outside is called a frequency following response (FFR).

EEG waves are current waves that occur according to brain activity, and can represent the state of the brain, and are classified into alpha waves (α waves), beta waves (β waves), and delta waves (δ waves).

Table 1 below summarizes the mental and physical states of each brain wave type and the frequency at that time.

frequency Brain wave Consciousness Mental and physical condition 30 Hz or more Gamma wave (γ) External consciousness Anxiety, excitement 13-30 Hz Beta wave (β) Normal brain waves
Working in a state of tension in response to the extraterrestrial 8-13
Hz 12-13 Hz Alpha wave (α) Fast
Alpha wave Dot product
Consciousness Attention and a little tension 9-11 Hz Middle
Alpha wave Improvement of study efficiency, mental unification, maximum memory, concentration,
Relieve stress 8-9 Hz Slow
Alpha wave Meditation, mindlessness meditation 4-8 Hz Theta wave (θ) Dot product
Consciousness Drowsiness, shallow sleep 0.5-4 Hz Delta wave (δ) unconscious Deep sleep

Based on the measurement results as described above, the brainwave induction technology uses the frequency-following reaction phenomenon to artificially tune a human brainwave to a specific desired frequency, thereby calming a user in a state of excitement or improving the user's learning ability. It is used for the purpose. At this time, a signal that induces an EEG is called an EEG signal.

According to the prior art, in order to generate an EEG induction signal, a binaural beat method using a difference between two signal sounds is commonly used. In the binaural beat method, for example, in order to create an EEG frequency of 11 Hz, which is less than audible sound, 300 Hz and 311 Hz are respectively generated and heard in both ears of the user, so that the user perceives 11 Hz, which is the difference frequency between the two frequencies. However, when the audible frequency band is used in the EEG induction signal, a problem arises that causes discomfort to the user and sometimes causes a headache due to the “beep” noise of the EEG induction signal.

The content providing unit 100 provides content, for example, audio and/or video content. First of all, audio and/or video content may be, for example, language-related materials such as language listening materials or language courses, and learning content such as learning lectures for elementary, middle and high school students, college students, or adults. It may be content for relaxation, such as a movie or sound of nature, quiet music that induces sleep, or content for sleep previously designated for sleep as the sound of nature. The content provided by the content providing unit 100 may include content identification information (eg, information on a pre-categorized category) in the form of an identification tag or the like. When the content providing unit 100 stores such content in a database, the corresponding content may be stored for each category (eg, content for learning, content for relaxation, content for sleep, etc.) pre-categorized in the database.

On the other hand, the content providing unit 100 may be implemented as being included in the EEG induction device 10 as an embodiment, and as another embodiment, as a configuration separate from the EEG induction device 10, the EEG on a network such as the Internet. It may be implemented as being included in a remote server capable of communicating with the induction device 10. In addition, the content providing unit 100 may provide the content stored in the database 110 including the database 110 for storing the content, or may receive and provide the content in real time from the outside in real time. In addition, the content provided by the content providing unit 100 may be provided to the EEG induction signal generator 200, and the EEG induction signal output unit 300 or the EEG induction device 10, which will be described later, may be used to reproduce the content. It may be provided as an embedded content playback device or a separate content playback device connected to the brain wave induction device 10. The content providing unit 100 may provide only content identification information to the brain wave induction signal generation unit 200.

The EEG induction signal generation unit 200 includes a content identification unit 210, an EEG induction signal generation unit 220, a control unit 230, and a mode input unit 240.

The content identification unit 210 receives audio and/or video content provided from the content providing unit 100, and whether the corresponding content is a content for learning, a content for relaxation, or a content for sleep from the content identification information included in the content. It is possible to identify or receive only content identification information. If content identification information is not included in the content, the EEG induction signal output unit 300, which will be described later, gives a command to the control unit 230 to provide a guide for querying the user in which mode the EEG induction device 10 is to be used. The audio output unit 310 or the display unit (not shown) integrated or connected to the EEG induction device 10 may provide a user with a guide for inquiring about which mode to use the EEG induction device 10 in.

In one embodiment, the EEG induction signal generation unit 220 stores various types of EEG information and generates EEG induction signal data corresponding to the corresponding EEG information. The EEG induction signal according to the present invention refers to a signal having the same frequency and waveform as an alpha wave, a beta wave, theta wave, and a delta wave, which are types of brain waves. When the EEG induction signal having the same frequency and waveform as the alpha wave, beta wave, theta wave, delta wave, etc. of the EEG is provided to the user through the EEG induction signal output unit 300 to be described later, the user's brain According to the frequency-following reaction, which is a phenomenon of the brain trying to match the frequency, a type of EEG corresponding to the frequency of the EEG induction signal is generated.

More specifically, the EEG induction signal generation unit 220 generates EEG induction signal data based on EEG information according to the type of content. For example, when generating an alpha wave, analyze the fundamental sound frequency and waveform of the content, generate an alpha wave having a specific frequency band using the fundamental sound frequency of the content, and determine the sound pressure of the generated alpha wave. To generate an EEG-guided signal. In this case, the method of using the fundamental acoustic frequency of the content generates an EEG induction signal having the same frequency as the frequency of the alpha wave by frequency synthesizing a base frequency and a modulated prequency obtained by modulating the fundamental frequency. In the same way, if a beta wave is required according to the type of content, the fundamental frequency and the modulation frequency are frequency-synthesized to generate an EEG induction signal similar to the frequency of the beta wave. As the types of EEG induction signals that can be output from the EEG induction signal output unit 300 to be described later, there may be signals having the same frequency and waveform as alpha waves, theta waves, and delta waves, respectively. More specifically, a signal having the same frequency and waveform as the alpha wave may be subdivided into signals having the same frequency and waveform as the slow alpha wave, the alpha wave, and the fast alpha wave, and stored in the brain wave induction signal generator 220. Additionally, the EEG induction signal generation unit 220 may include a signal having the same frequency and waveform as a beta wave less than an audible frequency among beta waves.

Unlike conventional techniques, the EEG induction device 10 according to the present invention provides a signal having the same frequency and waveform as that of a human brain wave as a brain wave induction signal, so that the user's brain is provided from the EEG induction device 10. By synchronizing to the EEG induction signal, EEG having the same frequency and waveform can be generated. In addition, the frequency band of signals useful for inducing brain waves is mainly less than 20 Hz. However, since human audible sound is usually in the range of 20Hz to 20000Hz, most people cannot hear the EEG-guided signal. Accordingly, when a user plays content to learn, listens to music, or sleeps, the EEG induction signal of the inaudible band is received, so that it may not be disturbed by noise caused by the EEG induction signal. In addition, it is possible to solve problems such as headache occurrence due to noise of a conventional brain wave induction signal having an audible frequency.

In addition, the EEG induction signal generation unit 220 includes a plurality of types of EEG induction programs. The EEG induction program refers to a program file that can generate an EEG induction signal having the same frequency and waveform as alpha wave, beta wave, theta wave, delta wave of EEG, and the frequency of the EEG induction signal according to the execution of each program file is It can be manufactured to be adjustable within a certain range.

The brainwave induction program is provided to the user in response to the above-described content identification information (e.g., information on pre-categorized categories such as learning content, relaxation content, sleep content, etc.) of the input audio and/or video content. It may include an algorithm that can determine the type (mode) of the brainwave induction signal that can be. For example, the brainwave induction program stored in the brainwave induction signal generation unit 220, when the content identification information of the audio and/or video content provided to the content identification unit 210 indicates that the content is a learning content, the brainwave induction As a signal, a predetermined algorithm may be included to generate a signal having a frequency and a waveform corresponding to a fast alpha wave or a middle alpha wave corresponding to an EEG generated when the user's attention concentration and learning ability are improved. In addition, when the content identification information of the audio and/or video content provided to the content identification unit 210 indicates that the content is a relaxation content, a frequency corresponding to the slow alpha wave corresponding to the brain wave generated during the user's meditation It may be to include a predetermined algorithm to generate a signal having a. Likewise, when the content identification information of the audio and/or video content provided to the content identification unit 210 indicates that the content is a sleep content, the theta wave or delta wave corresponding to the brain wave generated when the user sleeps. It may include a predetermined algorithm to generate a signal having a frequency and a waveform. In this case, a signal having a frequency and a waveform corresponding to the theta wave generated during drowsiness and shallow sleep is generated from the initial point of playback of the sleeping content until a predetermined time elapses, and after the predetermined time elapses, a deep signal is generated. It may be programmed to generate a signal having a frequency and waveform corresponding to the delta wave generated during sleep.

As another embodiment, according to the EEG induction device 10 of the present invention, when a user selects a desired mode, information indicating a mode selected by the user in the mode input unit 240 to be described later (hereinafter referred to as “mode display information”) ) May be input and an EEG induction signal corresponding to the corresponding mode display information may be provided to the user. The mode that can be selected from the user may include a learning mode, a rest mode, a sleep mode, and the like as an embodiment, or may include an alpha wave generation mode, the theta wave generation mode, and the like as another embodiment. have. In the above case, the EEG induction signal generation unit 220 has EEG information corresponding to each mode indication information and EEG induction signal data mapped to each other, and generates EEG induction signal data corresponding to each mode or a previously generated signal. When a user selects a desired mode by calling, an EEG induction signal corresponding to the mode may be provided to the user through the EEG induction signal output unit 300 to be described later.

As another embodiment, the EEG induction program is the type (mode) of the EEG induction signal that can be provided to the user according to characteristics such as frequency, waveform, tone, etc. of the audio included in the input audio and/or video content. Including an algorithm to determine whether the input audio and/or video content corresponds to learning content, relaxation content, sleep content, etc., and provides an EEG induction signal corresponding thereto. You can also make it possible.

The control unit 230 is connected to the content identification unit 210, the brain wave induction signal generation unit 220, the mode input unit 240, and the like, respectively, to identify and reproduce audio and/or content files, and to output an EEG induction signal accordingly. It controls a series of actions. The control unit 230 generates a control signal for the operation of each component so that the EEG induction signal can be provided from the EEG induction signal generation unit 230 to the EEG induction signal output unit 300 to be described later according to the control signal. do.

The mode input unit 240 performs a function of receiving a command from a user to determine a type (ie, mode) of an EEG induction signal for inducing EEG by a frequency following reaction. The mode that the user can select is an embodiment, and may be classified into various life-related modes, for example, a learning mode, a rest mode, and a sleep mode. As another embodiment, it may be classified into an alpha wave mode (more specifically, a fast alpha wave mode, a middle alpha wave mode, a slow alpha wave mode), a beta wave mode, theta wave mode, and a delta wave mode.

When the user selects one of these modes, the mode input unit 240 receives the selection from the user and transmits the input to the control unit 230. The control unit 230 receives the EEG induction signal data corresponding to the mode selected by the user from the EEG induction signal generation unit 220, processes the data, and provides it to the EEG induction signal output unit 300.

For example, in the example classified as a learning mode, a rest mode, and a sleep mode as the various life-related modes, when the user selects the learning mode, the mode input unit 240 receives a selection from the user and the control unit ( 230). The control unit 230 receives data on a signal having the same frequency and waveform as the fast alpha wave and/or the middle alpha wave as an EEG induction signal corresponding to the learning mode, and processes the data from the EEG induction signal generation unit 220 to process the fast signal. A signal having the same frequency and waveform as the wave and/or middle alpha wave can be transmitted to the brain wave induction signal output unit 300. Likewise, when the user selects the rest mode, the signal having the same frequency and waveform as the slow alpha wave can be transmitted to the EEG induction signal output unit 300 through the same method as the above process, and the user selects the sleep mode. When selected, a signal having the same frequency and waveform as the theta wave or delta wave can be transmitted to the brain wave induction signal output unit 300.

In addition, the EEG induction device 10 includes a mode button that can transmit an input regarding a mode selection from a user to the mode input unit 240 to the mode input unit 240, a power button for turning on/off the power, and a power button for controlling the volume. It may include a volume button and/or an operation time setting button.

The EEG induction signal output unit 300 performs a function of generating an EEG induction signal for inducing EEG and providing it to a user.

As an embodiment, the EEG induction signal output unit 300 may include an audio output unit 310 to provide the EEG induction signal to a user in the form of a sound source having an inaudible frequency. That is, by outputting an EEG induction signal from the EEG induction signal output unit 300, a sound having the same frequency and waveform as that of the EEG may be resonated to induce a corresponding EEG to a user. In this case, a pulse beat may be used as an EEG induction signal. In some cases, a binaural bit may be used. The audio output unit 310 may include at least one of an earphone, a headset, and a speaker.

For example, the EEG induction signal output unit 300 may generate the EEG induction signal in the form of a pulse train. That is, if a carrier audible sound having a specific frequency, for example, an audible sound frequency signal of 300 Hz, is intercepted 10 times in 1 second, an EEG induction signal of 10 Hz is generated, and if it is intercepted 15 times in 1 second in the same manner, an EEG induction signal of 15 Hz Can be created.

In addition, the EEG induction signal in the form of a pulse train provided from the EEG induction signal output unit 300 may be implemented in a mono method, or when implemented in a stereo method, the EEG induction signals of both channels are synchronized and output at the same time, or both It is also possible to alternately and repeatedly output the EEG induction signal of the channel.

As another embodiment, the EEG induction signal output unit 300 may further include a vibration output unit 320 that converts the EEG induction signal into a vibration signal and transmits it to the skull. This may be implemented by adding a piezoelectric vibration element 340 to a conventional earphone.

On the other hand, the EEG induction signal output unit 300 processes audio and/or video content provided from the content providing unit 100 in addition to the above-described EEG induction signal in the audio output unit 310 to provide audio with the above-described EEG induction signal. And/or video content may be provided to the user. In this case, the EEG induction signal output unit 300 may output only the EEG induction signal according to a user's selection or a preset condition of the EEG induction device 10, or only output audio and/or audio of video content. Yes, you can print both.

In addition, the EEG induction device 10 may further include a display or may be connected to a display device separate from the EEG induction device 10, so that an image of video content may be provided to the user.

Meanwhile, the brain wave induction device 10 according to the present invention may be implemented as a learning assistance device for a user (learner). In other words, as described above, a fast alpha wave corresponding to an EEG generated when learning content (language or learning courses, etc.) is identified and corresponding to the EEG guidance signal (e.g., a user's attention and learning ability is improved) Alternatively, it may be driven to generate a signal having a frequency and a waveform corresponding to the middle alpha wave. In this case, the EEG of the learner is tuned to the EEG signal corresponding to the fast alpha wave or the middle alpha wave generated by the EEG induction device 10 to improve the learner's learning ability. In addition, the EEG induction device 10 identifies rest content (music, movies, etc.) and a corresponding EEG induction signal (for example, a slow alpha wave corresponding to an EEG generated during meditation by a user). It can be implemented in a manner that is driven to generate a signal having a frequency and a waveform). In this case, the EEG of the learner is synchronized with the EEG signal corresponding to the slow alpha wave generated by the EEG induction device 10 to relieve stress or tension of the learner. Likewise, the EEG induction device 10 may assist the learner to take a good night's sleep by identifying the sleep content (such as music for sleep or sounds of nature) and using an EEG induction signal corresponding to a theta wave or a delta wave.

In addition, the brainwave induction device 10 according to the present invention is a content reproducing device, for example, a TV, a computer, a mobile phone, a portable device for learning, an IPTV set-top box, an audio player, an electronic dictionary, a game machine, a learning device such as an EEG induction device, It may be implemented in a form embedded in a sleep induction device, a stress relief device (eg, a massage chair), or the like, or may be implemented as a separate device that can be connected to the above-described device. When the brain wave induction device 10 is implemented in a form embedded in devices such as a television and a computer, the brain wave induction signal output unit 300 is integrated with the audio output unit of the device such as a television and a computer. It can be a form.

For example, when the EEG induction device 10 is embedded in a television or implemented in connection with a television, while a user (learner) learns the educational content through a television, the EEG induction device embedded in the television or connected to the television ( 10) generates an EEG induction signal corresponding to the educational content (e.g., an EEG induction signal corresponding to a fast alpha wave or a middle alpha wave) to generate an audio output unit (speaker, earphone, etc.) or an EEG induction device ( It may be provided to a corresponding user through the EEG induction signal output unit 300 of 10).

At this time, in the step S4, the control unit 230 generates a command to provide a guide for inquiring about which mode to use the EEG induction device 10 to the user, and the audio of the EEG induction signal output unit 300, which will be described later, is generated. It is delivered to the output unit 310 or a display unit (not shown) integrated or connected to the EEG induction device 10 to provide a user with a guide for inquiring about which mode to use the EEG induction device 10 in.

In addition, in relation to step S5, the EEG induction device 10 is provided with a mode button (not shown), so that when the user selects or inputs a desired mode with the mode button, it is input by the mode input unit 240. It receives and transmits the corresponding mode display information to the controller 230. The control unit 230 has the information on the mode inputted from the mode input unit 240 and executes the EEG induction program generated by the EEG induction signal generator 220 in the same manner as in step S2 to display the mode display information. Corresponding EEG induction signal data is selected, and the selected EEG induction signal data is transmitted from the EEG induction signal generation unit 220 to the audio output unit 310 or the vibration output unit 320 of the EEG induction signal output unit 300 (Step S2'). Step S3 which proceeds after is the same as described above.

On the other hand, in the above-described step S1, the content identification information is not included in the content data input to the content identification unit 210 or the content identification information is not read, the audio output unit 310 or the display (not shown) to the user After the step (S4) of providing a guide for inquiring about which mode to use the EEG induction device 10 is performed, a step (S5) of receiving a mode selected from the user in the mode input unit 240 may be performed. Since the user may arbitrarily select a mode, step S5 may be executed when the user selects or inputs a desired mode with the mode button without step S4 (see FIG. 3C).
