1 is a diagram illustrating an EEG inducing contents system according to an embodiment of the present invention.

Referring to FIG. 1, an EEG inducing contents providing system 100 according to an embodiment of the present invention includes a user device 110 and a server 120.

The user device 110 is a device wearable on a part of the user's body, measures a user's brain wave, and recommends and provides the brain wave induced content for reaching the target state based on the measured brain wave.

For example, the type of user device 110 may be implemented in the form of a wireless earpiece or the like. However, it is to be understood that the user device 110 is not necessarily limited to a wireless earset, but may be provided in various forms.

In addition, in the embodiment of the present invention, it is assumed that the device for measuring / measuring the user's brain wave and recommending / providing the EEG-derived content for reaching the target state based on the EEG is one device, It is a matter of course that the device for recommending / providing the EEG-derived content for reaching the target state based on the measured EEG may be a separate device.

In addition, a separate application for providing EEG derived contents based on the user's measured EEG may be installed in the user device. In this case, the type of the user device may be various types of electronic devices such as, for example, a mobile communication terminal such as a smart phone, a notebook, a tablet PC, a PMP, an air purifier, an air conditioner,

The server 120 is an apparatus for interfacing with the user device 110 and providing the recommended EEG inducing contents in the user device 110. [ Depending on the implementation method, the server 120 may be included and the server may not be included in the system.

However, it may be desirable to provide more variety of types of EEG derived content and to have the server 120 for updating the EEG derived content.

Hereinafter, a method of providing an EEG-derived content for reaching a target state based on a user's measured EEG will be described in detail.

Referring to FIG.

In step 210, the user device 110 receives (or selects) a target state. Here, the target state may be a state that the user wants to reach. The user device 110 may output the target state via the screen. The screen interface outputting the target status is illustrated in Fig.

Referring to FIG. 3, the target state is a sleep state, a sleep state, a short sleep, a refreshing morning, an improvement in concentration, an improvement in memory, an improvement in creativity, a condition optimization, a sleepiness awakening, a mood increase, , Relaxation, and so on. It should be appreciated that the target state shown in FIG. 3 is only one example provided for the convenience of understanding and explanation, and that the target state can be classified differently according to the implementation.

In step 215, the user device 110 measures the user's brain waves.

In an embodiment of the present invention, it is assumed that the user device 110 measures a user's brain wave, but it is natural that a separate device for measuring a brain wave of the user may be provided. In this case, the user device 110 can receive the measured brain waves through a separate device.

Also, because of the limitations of the paper, it is described that the user device 110 measures the user's brain waves one-time, but the user device 110 may also measure the user's brain waves periodically or aperiodically.

The present invention is for recommending / providing contents that can induce EEG according to a target state that the user desires to reach based on the measured EEG. In order to facilitate understanding and explanation, the types of brain waves will be briefly described with reference to FIG.

The types of brain waves include gamma waves, beta waves, alpha waves, theta waves, and delta waves, as shown in FIG. These EEG waves are different in frequency and can be seen to be expressed in different states.

A detailed description of each type of EEG is shown in Fig.

In addition, the measured EEG may be output as shown in FIG. As shown in FIG. 5, it is a matter of course that the measured brain waves and the brain beat frequency according to the target state selected by the user can be output together.

In step 220, the user device 110 determines a brain beat frequency for the target state based on the measured EEG.

To facilitate understanding and explanations, the brain bit will be briefly described. A brain beat is felt when two coherent sounds of similar frequency are heard through both headphones and speakers. The brain combines the two signals to create a sense of the third sound, brain beat, which is generated from the nucleus of the olive nucleus of the brainstem, which is the point where this information is relatively integrated, To the net-like structure that causes the neurons.

For example, if you supply a sound of 200 Hz to the left ear and a sound of 210 Hz to the right ear, the sound of the 10 Hz gap will stimulate brain wave conversion.

The user device 110 may use the user's measured brain waves to determine this brain beat frequency. To be more specific, the user device 110 determines the brain beat frequency corresponding to the target state. The user device 110 may then correct the determined brain beat frequency using the measured brain waves.

The brain bit frequencies may be respectively mapped corresponding to respective target states. Thus, when the user selects the target state, the corresponding brain beat frequency can be determined.

For example, assume that the user has selected the target state as "focused ". The brain beat frequency "10 Hz" can be determined in response to the "concentrated" state selected by the user. If the user's measured EEG is "3 Hz, " the user device 110 may correct the brain beat frequency using the measured EEG" 3 Hz. &Quot; That is, when the measured EEG exceeds the reference value and a difference occurs with the brain beat frequency, the user device 110 can increase and decrease the brain beat frequency differentially according to the difference between the reference value and the measured EEG.

That is, the correction value of the brain bit frequency may be a result of adding the difference between the reference value and brain waves to the brain bit frequency. 10 Hz + (5 Hz-3 Hz) = 12 Hz.

FIG. 6 illustrates a brain beat frequency output screen interface according to an embodiment of the present invention.

In step 225, the user device 110 recommends / provides EEG induced content according to the brain beat frequency.

Here, the EEG induced content may be at least one of white noise and functional content. In this specification, it is assumed that the EEG induced content includes both white noise and functional content (music), and the description will be focused on this.

The white noise is classified according to the change pattern (pitch) of the pitch, volume, and tone, and the less the change of the pitch, volume, and tone is, the more stable the sound is, so it can be matched with the lower brain beat frequency.

Also, the change of the tone of the white noise means changing the kind of sound, and it can be used by mixing various kinds of sounds. For example, you can mix different types of sounds, such as "Sound waves -> waves + thunder + rain -> waves + thunder -> waves" to include various patterns.

The white noise according to an embodiment of the present invention should be understood as a low frequency white noise due to natural sounds such as waves, water, birds, eclipse, rain, etc. (see FIG. 7). Generally, it should be understood that a white noise mixed with a high frequency that can be heard on a TV or a radio is excluded from the present invention.

The white noise according to an embodiment of the present invention plays an auxiliary role of brain beat, which is a main means of inducing EEG.

The user device 110 may determine the functional content (music) using the brain beat frequency. For example, the functional content can be selected according to the tempo of the music and / or the pitch, volume, and change pattern (degree) of the silver color. That is, the slower the tempo, the more stable the content, so it can be matched with the lower brain beat frequency. In addition, the smaller the change in the pitch, volume, and tone, the more stable the sound, so it can be matched with the lower brain beat frequency.

The functional music can be selected according to the tempo of the music or / and the changing pattern of the pitch, volume, and tone of the music. Here, the change pattern may indicate the degree of change per unit time.

The slower the tempo, the more stable the music, so it can match the lower brain beat frequency. The smaller the change in pitch, volume, and tone, the more stable the sound, so it can be matched with a lower brain beat frequency.

Functional changes in the tone of music can mean changing the type of instrument. For example, it could be a variation using different instruments, such as "guitar -> guitar + bass -> guitar + bass + drums -> drums"

When the brain beat frequency corresponding to the target state is determined, the brain wave induced content according to the brain beat frequency can be determined.

These functional contents play an auxiliary role for brainwave frequency and white noise.

For example, "white noise A, functional music A" for a delta wave, "white noise B, functional music B" for a seta wave, "white noise C, functional music C" White noise D, functional music D ", and gamma waves, such as" white noise E, functional music E ", each brain wave induced content is mapped according to each brain wave frequency.

Fig. 8 shows an example of functional music. The plurality of functional music corresponding to the brain beat frequency may be plural. Thus, the user may select any of a plurality of functional music provided through the user device 110 corresponding to the brain beat frequency.

In the embodiment of the present invention, it is assumed that the brain wave inducing contents corresponding to the brain beat frequency includes both the brain beat frequency, the white noise, and the functional music. However, You can select either white noise or functional music along with the brain beat frequency. In such a case, the EEG inducing contents may be generated by combining only one selected white noise or functional music together with the brain beat frequency.

FIG. 9 shows a screen interface for providing EEG inducing contents. As shown in FIG. 9, it is also possible to output an image based on any one of white noise and functional music at the time of outputting the EEG inducing contents. This may help the user to reach the desired target state.

In step 230, the user device 110 determines whether a predetermined time has elapsed after reproducing the EEG inducing contents.

If the predetermined time has not elapsed, the process waits at step 230.

However, if a certain amount of time has elapsed, the user device 110 again measures the user's EEG in step 235.

In step 240, the user device 110 receives the satisfaction of the user.

Here, the satisfaction means satisfaction with the recommended / provided EEG induced content according to the target state selected by the user. The user device 110 may display the satisfaction level from the lowest to the highest level visually through the UI and receive the satisfaction by selecting one of the steps from the user.

In step 245, the user device 110 recalculates the brain beat frequency using the remeasured EEG.

For example, if the user device 110 compares brain beat frequencies according to the re-measured EEG and target states, and if the difference exceeds the reference value, the user device 110 resets the brain beat frequency differentially according to the difference exceeding the reference value . In addition, the user device 110 may increase or decrease the volume of the rescheduled brain beat frequency based on a difference exceeding a reference value.

For example, assume that the re-measured EEG is "7 Hz" and the brain beat frequency of the target state is "10 Hz". At this time, it is assumed that the brain beat frequency corrected by the previously measured EEG is "12 Hz ".

The recalibrated brain beat frequency may be 14 Hz (12 Hz + (3 Hz - 1 Hz)) because the difference (3 Hz) of the brainwave frequency of the remeasured EEG and the target state exceeds 2 Hz of the reference value (1 Hz).

In addition, the user device 110 may increase the volume level by two reference levels according to the degree (2 Hz) exceeding the reference value (1 Hz). At this time, it is assumed that one reference level of the volume is 10 dB. In such a case, the user device 110 may increase the volume of the recalibrated brain beat frequency by 20 dB.

In step 250, the user device 110 changes the EEG induced content by reflecting the weight based on the inputted user satisfaction.

For example, when the user satisfaction level is lower than or equal to the middle level, the user device 110 may change the level of the user's satisfaction to the level of the EEG level.

That is, in the case of delta wave, "white noise A, functional music A", "white noise B, functional music B" in the case of theta wave, "white noise C, functional music C" D, functional music D "for gamma waves, and" white noise E, functional music E "for gamma waves.

When the user satisfaction level is "2 (middle "), the user device 110 can change white-noise level and functional music to level-induced content. That is, when the current stage is provided with EEG derived content corresponding to the alpha wave, the user device 110 may change and provide the EEG derived content corresponding to the beta wave above one level.

For another example, if the user satisfaction is "1 (lower) ", the user device 110 may apply the white noise and probable music above two levels to change the EEG derived content. In other words, it is possible to provide an alteration to the EEG induced content corresponding to the gamma wave on the two levels corresponding to the alpha wave.

For example, the sound output unit 1015 may be a speaker. Of course, it is needless to say that the sound output unit 1015 may be provided in the form of an earset.

The input unit 1020 is a means for receiving a command for controlling the user device 110. For example, the input unit 1020 may select any one of the target states output through the display unit 1025.

The input unit 1020 may be realized by at least one key button or a touch pad.

The display unit 1025 is means for outputting various time information.

For example, the display unit 1025 may be a liquid crystal display (LCD).

It is assumed that the input unit 1020 and the display unit 1025 are separately configured in the embodiment of the present invention. However, the input unit 1020 and the display unit 1025 may have one configuration such as a touch screen.

The memory 1030 stores various program codes (commands) necessary to provide brain wave induced content corresponding to a brain beat for reaching a target state based on the measured brain wave of the user according to an embodiment of the present invention. And various data derived from the process.

Processor 1035 may be coupled to internal components of user device 110 (e. G., Brain wave measurement unit 1010, acoustic output unit 1015, input unit 1020, 1025, memory 1030, and the like).
