Abstract
Description
The present invention relates to a learning environment control method, and more particularly, to a learning environment control method using an EEG.
Generally, brain waves are biological signals that directly or indirectly reflect human consciousness or unconscious state, and refers to a wavelength having a frequency of 30 Hz or less with a potential difference of tens of microvolts measured in all regions of human scalp.
These EEGs are classified into a delta wave, a theta wave, an alpha wave, a beta wave, and a gamma wave by frequency band. Delta waves are typically EEG waves with a frequency of less than 4 Hz and are typical of normal sleep states. Theta waves are those with frequencies in the range of 4 to 8 Hz and are often present when the state is mentally disturbed or distracted, often in adolescents with learning disabilities .
The alpha wave is an electroencephalogram with a frequency of about 8 to 12 Hz, which is generally stable when the mental state is stable, and the eye is closed and taking a relaxed psychological state. Alpha waves also occur when there is a high degree of concentration to separate from the surrounding situation, or when psychological stabilization has occurred due to meditation. Gamma wave is an EEG having a frequency of 30 to 50 Hz and appears in an excited state.
Beta waves refer to the EEG with a frequency of about 12 to 30 Hz, which is mainly observed when a little tension or attention is paid. Beta waves are widespread throughout the brain when exercising, learning, or performing tasks. The beta wave is divided into an SMR wave having a frequency of 12 to 15 Hz, an intermediate beta wave having a frequency of 15 to 18 Hz, and a high-beta wave having a frequency of 20 Hz or more. Beta waves are more stressful when exposed to stress such as anxiety or tension.
When attention is paid, SMR wave appears. When concentrated and normal activities are performed, middle beta waves with a frequency of 15 to 18 Hz appear in the left brain and Kobe beat exceeding 20 Hz appears when tension and anxiety continue.
The present invention provides a learning environment control method capable of improving concentration using brain waves.
A learning environment control method using EEG according to an aspect of the present invention includes a step of receiving an EEG receiving EEG, an EEG analysis step of classifying and extracting EEG types according to a frequency from a received EEG, And a color temperature control step of determining a user's concentration according to the change of brain waves and changing a color temperature of the illumination.
In addition, the sinking step may include a picture display step of displaying a picture on the display.
In addition, the sinking step may include a brain wave change recognition step of recognizing a change of a user's brain wave appearing according to a picture display.
Further, in the EEP change recognition step, it can be determined that there is a sink doctor when the intensity of the setter becomes lower and the intensity of the SMR wave and the middle beta wave become higher.
Also, the EEG recognizing step can determine that there is a sink doctor when the intensity of the alpha wave is decreased in the right hemisphere and the alpha wave is not changed in the left hemisphere.
In addition, the sinking step may include a sink signal generating step of, when the user's brain wave change coincides with a preset pattern, transmitting a pairing signal to the electronic device to wait for the electronic device to receive the driving signal.
In addition, the color temperature control step may include a concentration determination step of determining a degree of concentration of the user.
In addition, the concentration determination step may determine that the user is concentrating when both the SMR wave and the intermediate beater increase and the increase amount of the SMR wave is larger than the increase amount of the middle beta wave.
Also, the concentration determination step may divide the degree of learning concentration by dividing the sum of the output value of the SMR wave and the output value of the middle beta wave by the output value of the three waves.
The color temperature adjusting step may include a color temperature changing step for increasing the color temperature of the illumination when the concentration is decreased.
Also, when it is determined that the color temperature changing step is in the concentrated state, the color temperature of the illumination can be controlled to 5500K to 6500K.
Also, when it is determined that the color temperature changing step is a rest state, the color temperature of the illumination can be controlled to 3000K to 4000K.
In addition, the environmental control method may further include a step of adjusting illuminance of the illumination, and the illuminance adjusting step may increase the illuminance when the concentration is decreased.
Further, when it is determined that the illuminance control step is in the concentrated state, the illuminance of the illumination can be controlled from 750 lux to 850 lux.
In addition, the environment control method may further include a background sound wave adjusting step of adjusting a background sound wave according to a change in brain waves.
In addition, the background sound wave adjusting step may generate a true sound wave having a frequency of 1 Hz to 1 kHz when the Kobe beat is increased while the concentration is maintained.
In addition, the background sound wave adjusting step may generate a sound wave having a frequency of a frequency band lower than the audible frequency.
As described above, according to the present invention, it is possible to improve the concentration by controlling the color temperature, illumination, and sound waves according to the change of EEG.

Hereinafter, a learning environment control method using the EEG according to the first embodiment of the present invention will be described with reference to FIG. FIG. 3 is a flowchart for explaining a learning environment control method using an EEG according to the first embodiment of the present invention.
1 to 3, a learning environment control method using an EEG according to the first embodiment includes EEG reception step S101, EEG analysis step S102, Sink step S103, S104), and a background sound wave adjusting step (S105).
The EEG reception step (S101) receives the EEG transmitted from the EEG device (20). The EEG receiving step (S101) can receive brain waves from the EEG device 20 by wireless communication.
The EEG analysis step (S102) classifies and extracts the kinds of EEG according to the frequency from the received EEG. The

The filtering step includes a plurality of analog filters to filter various noise included in the brain waves amplified by the
The sync step S103 recognizes the EEG changes and waits for the electronic apparatus to be controlled by the EEG. The sinking step S103 may include a character displaying step, a brain wave change recognizing step, and a sink signal generating step.
The character display step displays a character on the display, but displays the character to be moved. The step of recognizing the EEG changes recognizes the change of the user's brain waves appearing according to the display of the characters. When a user recognizes a moving character, eye movement occurs and the intensity of the delta wave increases, and the intensity of the SMR wave increases in the process of reading the character. Thus, when the intensity of the delta wave is increased and the intensity of the SMR wave is increased, it can be judged that there is a sink doctor.
In addition, the appearance of alpha waves in the process of recognition of letters and pictures is different. During the linguistic task, the intensity of the alpha waves decreases in the left hemisphere, there is no change in the alpha waves in the right hemisphere, While performing spatial tasks, the intensity of the alpha wave is decreased in the right hemisphere and there is no change in the alpha wave in the left hemisphere. In the EEG phase recognition step, we think that there is a sink doctor when the intensity of the alpha wave is decreased in the left hemisphere and the alpha wave is not changed in the right hemisphere. In the sink signal generating step, the sync signal is transmitted to the electronic device, and the electronic device switches to the standby state so that the drive signal can be received.
The color temperature control step (S104) includes determining concentration of the user according to the change of brain waves, changing the color temperature of the
In the concentration determination stage, both the SMR wave and the middle beat peak are increased, and the increase in the SMR wave is detected as being larger than the increase in the middle beta wave and it is recognized that the concentration is concentrated. In the learning state, both the SMR wave and the middle beta wave increase, and the increase of the SMR wave is larger than the increase of the middle beta wave by recognizing and thinking of the character. Thus, the concentration determination step recognizes such a state as a state in which the user is concentrated. In the present description, the amount of increase in all kinds of brain waves is measured by a voltage.
In the concentration determination step, the concentration can be quantified and stored. The value obtained by dividing the sum of the output value of the SMR wave and the output value of the middle beta wave by the output value of the half wave is defined as the learning concentration. A high concentration means that the user is immersed in study, and a low concentration of learning means that the user is in a learning state but distracted.
In the state of concentration on learning, the decrease of the cetapha reflecting the level of unconsciousness increases, the SMR wave which means the attention power around the periphery, and the middle beta wave which means the immersion concentration power that is immersed in one object. Therefore, the degree of concentration of the user in the learning state can be grasped more clearly by calculating the learning concentration as described above.

The background sound wave control step S105 may include a stress determination step for determining whether Kobe beat is increased or a sound output step for generating a true sound wave having a frequency of 50 Hz to 1 kHz when Kobe beat increases. The sound waves may be output through the
The sound wave output stage can reduce the frequency of the sound wave when the Kobe beat increases while the concentration is maintained and the background sound wave controller can generate a sound wave having a frequency of 1 Hz to 30 Hz have.
