In this specification, the terms " comprising ", or " comprising " and the like should not be construed as necessarily including the various elements or steps described in the specification, Or may be further comprised of additional components or steps. Also, the terms " part, " " module, " and the like described in the specification mean units for processing at least one function or operation, which may be implemented in hardware or software or a combination of hardware and software . Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

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

Referring to FIG. 1, an EEG induction system 100 according to an embodiment of the present invention includes a wearable device 110 and a user terminal 120.

The wearable device 110 is a device for worn on the user's body, and is a means for measuring the user's physical condition. For example, wearable device 110 may be a smart watch. In order to facilitate understanding and explanation, the wearable device 110 is assumed to be a smart watch, but the wearable device 110 may be attached to or worn on a part of the user's body, such as Google Glass, All possible devices are equally applicable.

In this specification, it is assumed that the wearable device 110 is used to measure the physical condition of the user. However, the wearable device is not necessarily limited to wearable devices. It is natural that the present invention can be applied equally to all cases even when measured by a sensor capable of measuring a user's physical condition.

Hereinafter, the wearable device 110 will be collectively referred to as a wearable device 110 for convenience of explanation and explanation, but it should be interpreted as including a separate sensor or an electronic device capable of measuring a user's physical condition.

The user terminal 120 is an apparatus for interfacing with the wearable device 110 and acquiring a result of measuring the physical condition of the user from the wearable device 110 in real time and providing the user with an EEG induced content based on the result.

The user terminal 120 includes an EEG apparatus 130 capable of providing EEG induced contents based on the user's physical condition. The EEG apparatus 130 described below may be provided in a configuration of the user terminal 120 or may be installed in the user terminal 120 in the form of an app.

The type of the user terminal 120 may be various types of electronic devices such as a mobile communication terminal such as a smart phone, a notebook computer, a tablet PC, a PMP, an air cleaner, an air conditioner, Therefore, it should be understood that the EEG induction apparatus 130 described below is included in the configuration of the above-described electronic apparatus even though it is not described.

2 is a flowchart illustrating a method of providing contents for inducing EEG according to an embodiment of the present invention.

In step 210, the EEG apparatus 130 acquires the user's physical condition information. For example, the brain wave guiding device 130 may acquire various kinds of physical condition information of the user from the wearable device 110 in real time (periodically or non-periodically). Here, the user's physical condition information may be at least one of heart rate, stress index, oxygen saturation, respiratory rate, sleeping time, and deep sleep rate. For example, a deep sleep rate can be measured using motion information during sleep.

In step 215, the EEG apparatus 130 derives a body index using the obtained user's physical condition information.

For example, the user's body index can be derived using at least one of psychological state information, stress index, fatigue index, and sleep state information.

The psychological state information can be derived according to the heart rate. For example, the brain-wave inducing apparatus 130 may derive psychological state information according to whether the user's information is in a normal range in consideration of a reference heart rate or in a certain degree with respect to a normal range.

The stress index can be determined based on the measurement of changes in blood pressure, blood flow, pulse, and the like.

Fatigue index can be derived using measured oxygen saturation and respiratory rate. For example, fatigue index can be derived by considering at least one of oxygen saturation and respiratory rate in the normal range or considering the difference from the normal range.

Sleep state information can be derived using sleep time and a deep sleep rate.

The normal range of psychological state, stress index, fatigue index and sleep state are shown in Tables 1 to 4 below.

Psychological state Heart rate age 12 to 15 16-19 20 to 39 40 to 59 60 to 79 Over 80 years old male 66-83 61-78 61-76 61-77 60-75 61-78 female 70-87 69-85 66-82 64-79 64-78 64-77

stress Stress Index Less than 50%

Fatigue Oxygen saturation 95% or more Respiratory rate per minute male 20 or less female 22 or less

Sleep state Sleep time 6 hours Deep Sleep Rate More than 70%

Thus, psychological state information, stress index, fatigue index, and sleep state information are derived based on the above normal range, and body index can be derived using the information.

For example, the EEG apparatus 130 may calculate a state value by converting measured values of a psychological state, a stress index, a fatigue index, and a sleep state, as shown in Table 5 below, and derive a body index using the following equation (1) .

Psychological state
(A) Measures normal +5 +10 +15 +20 Status value 100 90 80 70 60 stress
(B) Measures 50% 60% 70% 80% 90% Status value 100 90 80 70 60 Fatigue
(C) Measures 95% ↑ & Normal 95% ↑ & more 95% ↓ & top 95% ↓ & exceed Status value 100 90 80 70 Sleep state
(D) Measures 6h ↑ & 70% ↑ 6h ↑ & 70% ↓ 6h ↓ & 70% ↑ 6h ↓ & 70% ↓ Status value 100 90 80 70

Or the body index may be expressed in the form of a percentage as shown in the following equation (2).

Here, A represents psychological state information, B represents stress index, C represents fatigue index, and D represents sleep state information.

The EEG 130 may derive psychological index and physical index prior to deriving the body index. Then, the brain wave induction apparatus 130 may derive the body index using the derived psychological index and the physical index.

Here, psychological index can be derived by using psychological state information and stress index. For example, psychological index can be derived by adding psychological state information and stress index.

In addition, physical indices can be derived using fatigue index and sleep state information. For example, a physical index can be derived by adding fatigue index and sleep state information.

Therefore, the brain-wave induction apparatus 130 may derive the body index by deriving the psychological index and the body index, respectively.

In operation 220, the brain wave induction apparatus 130 derives a brain beat frequency suitable for the user's current physical condition using the derived body index.

To facilitate understanding and explanations, the brain bit will be briefly described. A brain beat, or binaural beat, is felt when two coherent sounds of similar frequency are heard on both ears through headphones or 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.

In one embodiment of the present invention, the brain beat frequency can be derived based on the user's body index so as to generate such brain beat.

For example, the brain beat frequency can be derived using the following equation (3).

In one embodiment of the present invention, it is assumed that the brain beat frequency is derived from a maximum of 15 Hz to a minimum of 1 Hz based on the body index of the user, but the range of brain beat frequencies derived may be variously changed depending on the implementation and the surrounding environment Of course.

For example, if the body index (H) is up to 100%, the brain beat frequency can be derived with a beta wave of 15 Hz. On the other hand, if the body index (H) is at a minimum of 0%, the brain beat frequency can be derived as a delta wave of 1 Hz.

The brain waves are as shown in Fig. Accordingly, in one embodiment of the present invention, a brain beat frequency for deriving an appropriate brain wave according to a user's body index (H) can be derived.

In step 225, the EEG inducer 130 recommends EEG derived contents based on the derived brain beat frequency. Here, the EEG derived content includes a brain beat frequency, and may further include white noise and functional content (music).

For example, the brain wave induction apparatus 130 may recommend a white noise according to the brain beat frequency.

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. In this case, the change in the tone can occur as the type of sound being mixed is changed. (For example, waves -> waves + thunder + rain -> waves + thunder -> waves)

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, euphoria, rain, 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. Therefore, considering the user's body index (H), the volume of the white noise can be lowered and the volume of the brain beat frequency can be increased as the body condition of the user is worse.

The brain wave induction apparatus 130 can 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. In this case, the change of the tone may occur as the type of the musical instrument to be mixed is changed. (For example, guitar + bass-> guitar + bass + drums-> drums)

Functional content plays a supporting role for brainwave frequency and white noise. Accordingly, the brain beat frequency and the white noise volume, which play a decisive role in the induction of brain waves, can be set to be higher as the body index of the user becomes worse (i.e., the body condition of the user is worse).

In step 230, the EEG apparatus 130 corrects the EEG induced content using psychological index and physical index.

For example, when the psychometric index is higher than the body index (i.e., the physical fatigue is higher), the EEG apparatus 130 reflects the weight of the white noise to a high degree. Here, the weight of the white noise is reflected to reflect the volume corresponding to the white noise to a higher level, and to reflect the volume of the brain bit frequency to a lower level.

In the embodiment of the present invention, it is assumed that the brain bit contributes more in the psychological aspect and the white noise contributes more in the physical aspect.

In addition, when the physical index is higher than the psychological index (that is, when the psychological uneasiness and stress are higher), the EEG apparatus 130 reflects the weight of the brain beat frequency to a high degree. Here, the weight of the brain bit frequency reflects a high level, thereby lowering the brain bit frequency by one level to induce a more stable psychological state, to reflect the volume of the brain bit frequency to a greater extent, Which means to calibrate to reflect less.

Brain bits, white noise, and functional contents can be determined and corrected through the above-described steps 210 to 230, and an example thereof is shown in Table 6 below.

In step 235, the EEG induction apparatus 130 outputs (reproduces) the EEG induced content. At this time, the EEG apparatus 130 may output the EEG induced content in consideration of the user's body index (i.e., reflecting the user's body condition).

For example, since the user's body index is low, the brain wave induction apparatus 130 can output a brainwave frequency and a white noise volume, which are more important means for inducing brain waves than functional contents, because the user's body index is lower. Also, the lower the body index (ie, the worse the body condition), the higher the volume of the brain beat frequency than white noise can be output.
