Sleep accounts for one-third of the entire lifetime. Sleep is a very important health issue and is essential for life support. Sleep provides the most basic relaxation time for a person. Through sleep, energy is supplied to accumulate physical energy while supplementing the energy we used to work during the day. In addition, the brain rests at sleep time so that we can balance the appropriate activities, and the most necessary growth hormone is secreted in the growing child.

However, the importance of sleep is increasingly recognized, but most modern people are not getting enough sleep because of excessive work or study. What is important for sleeping is sleep quality rather than sleeping quantity. Especially, it is very important how deep sleep is taken. In modern times, most people do not ask for good sleep because of stress.

The causes of sleep deprivation and sleep disorder in modern people are various. In recent years, there has been an increase in mental illness due to psychological reasons such as depression, anxiety, stress, and so on caused by anxiety about the future due to economic difficulties and job hunting, insufficient sleep due to heavy work, fierce competition for survival, Day shift shifts due to diversification, and inappropriate lifestyle habits. In other words, as the society becomes more complicated, there is more work to do and more stress, so chronic sleep deprivation and sleep disorder are occurring. It is also one of the reasons to drink lots of caffeinated beverages such as coffee.

As society becomes increasingly diverse and complex and undergoing rapid change, many people are increasingly complaining about sleep disorders beyond mere sleep deprivation. Worldwide, sleep disorders are reported to increase by 20-30% annually.

Sleep disorders are associated with various symptoms such as depression, depression, emotional disturbances, cardiovascular disorders, sexual dysfunction and immune dysfunction, and cause many problems in daily life. Another indirect effect of sleep disorders is increased rates of diabetes, heart disease, depression, and obesity.

Due to sleep deprivation and sleep disturbances that modern people are experiencing, the cost of socioeconomic costs is greatly increasing. The lack of sleep and sleep disturbance increases the absenteeism rate, lowers the workforce and work ability, lowers productivity, and is the biggest cause of safety accidents and traffic accidents caused by decreased concentration and drowsiness. It also results in an increase in the cost of insomnia self-treatment and the cost of pharmacological treatment due to the illness caused thereby. This leads to an increase in negative socio-economic costs.

If you can not sleep for a certain amount of time, you should take a good night's sleep. Sleep improves vigorous brain activity, improves learning effectiveness, and promotes the secretion of growth hormone as well as secretion of immunity enhancers.

In order to take a good night's sleep, it is necessary to first determine the quality of the sleep and then to find a way to cope with it. It is also necessary to prevent sleep apnea and snoring which decrease the quality of sleep. It is necessary to wake up in a refreshing mood at the desired time. Accordingly, many techniques have heretofore been disclosed in order to quantify the quality of the sleeping water to derive the optimum sleeping time, to shorten the time of the sleeping time, and to induce comfortable and comfortable sleeping.

Third, the reliability is low by providing sleep environment of lighting or music unilaterally without reflecting instantaneous changing user 's sleep state,

Fourth, it is possible to directly measure the vital signs in the respiratory and chest, but the user may feel quite uncomfortable and may interfere with the sleep,

Fifth, it is possible to induce discomfort by forcing the weather by providing lighting and music at a fixed time,

Sixth, it is difficult to maintain a good sleep because the removal technique such as snoring and sleep apnea, which reduce the quality of sleep, is not applied efficiently,

Seventh, it is not enough to provide optimal sleep pattern information to the user by evaluating the quality of sleep by applying only the amount of body movement and sleeping environment, excluding snoring, snoring, sleep apnea,

Eighth, when sleeping in a bedroom or bed, the sleeping environment is also applied to the sleeping person at the same time, so there is an adverse effect due to the difference in the sleeping orientation of the individual, thus causing a problem of inducing and maintaining a comfortable sleep.

5 is a flowchart of an embodiment of a sleep phase analysis method for sleep control according to the present invention.

As shown in FIG. 5, the sleep phase analysis unit 210 is composed of a PPG / EOG signal processing unit S700 and a determination algorithm unit S701 to S712. The PPG / EOG signal processing unit S700 includes a signal processing function for the PPG signal and the EOG signal obtained from the PPG sensor module 110 and the EOG sensor module 120, and the determination algorithm units S701 to S712, A function of classifying the sleep phase into four stages, namely a sleep step (S710), a shallow sleep phase (S709), a deep sleep phase (S708), and a REM sleep phase (S711) using the PPG signal and the EOG signal after signal processing .

The PPG / EOG signal processing unit S700 removes motion artifacts caused by the motion of the user included in the signal obtained from the PPG sensor module 110 and uses an adaptive filter method, And a periodic moving average filter (PMAF) method can be used.

A peak is detected from the restored PPG signal to obtain a pulse-to-pulse interval (PPI), which is an interval between peak-peaks, and a pulse rate variability (PRV) . The PRV may be very influenced by external factors, such as the environment or psychological state, as well as the individual differences of the PRV.

In addition, the EOG signal received from the EOG sensor module 120 is alternately changed according to the motion of the pupil. The cornea of the eye has positive (+) charge and the retina has negative (-) charge, so there is naturally a few mV dipole between the cornea and the retina. Therefore, when the eyeball is moved to the left side, the left electrode is positive (+) and the right electrode is negative (-). Moving the eyeball to the opposite right will reverse the signal. These eye movements appear intermittently during normal NREM (non-rapid eye movement) sleep days, but vigorously during REM sleep days.

In the PPG / EOG signal processing unit S700, the EOG signal may be calculated in the form of frequency of eye movements (frequency), power spectral density, or the like so as to help determine REM sleep.

First, the purpose of the judgment algorithm for the sleep phase analysis derived from the present invention will be described as follows.

It is called the R-K rule of the sleep classification after the initials of Rechtschaffen & Kales, which proposed a heuristic set that classifies sleep into five levels based on EEG. Sleep 1 is the shallowest and sleep 4 is the deepest sleep. And there is a paradoxical sleep that is unrecognized even though the subject's EEG resembles a completely conscious subject. In this sleep stage, the wind is called REM sleep because the eye moves rapidly under the eyelid, and it is known as dream sleep because it dreams mainly at this time. Thus, Sleep 1 ~ 4 stages are known as NREM sleep.

The average daily average sleep time for an adult is 7.5 to 8 hours. Repeat the NREM sleep surface for 1 to 4 times, then again for 2 to 4 times per night for an average of 90 minutes to the REM level. The NREM sleep time decreased as the cycle progressed, while the REM sleep time increased, and 75% of the overnight sleep time of the normal adult was the NREM sleep time (sleep 1, 5%, sleep 2, 50%, sleep 3 and 4 ; 20%), and 25% is the REM sleep time.

Although the sleep classification according to the RK-based EEG rule can be accurately classified through sleep polyvalence test in the sleep test room, when the sleep phase is analyzed in the movable condition, the EEG signal is small, and the small movement of the subject or the severe fluctuation Of course, involve many problems that require many parameters to analyze the sleep phase.

Accordingly, in the present invention, a PRV that uses a relatively low level of biological signal level and easy measurement in the sleep phase analysis is used for the ubiquitous sleep management of the portable base.

In addition, in the classification of the sleeping phase, the first stage of sleep constitutes about 5% of the total sleeping water, and the third and fourth stages of sleep constitute 20% of the total sleeping water due to the deep sleeping. Therefore, The sleep stages 3 and 4 are divided into four stages: deep sleep stage (S709), deep sleep stage (S708) or SWS (Slow Wave Sleep), REM sleep stage (S711) and arousal phase (S710) .

Therefore, the judgment algorithm units S701 to S712 for the sleep phase analysis will be described in detail with reference to FIG.

When the water surface is started, the PPG sensor module 110 and the EOG sensor module 120 process the PPG signal and the EOG signal (S700). The PRV obtained from the signal processing of PPG is used to calculate the power density in the frequency domain by using FFT (fast Fourier transform) and STFT (short time fourier transform), or by using an AR (autoregressive) model using the peak- Can be calculated. Next, the power in the low-frequency band (0.04 to 0.15 Hz) and the high-frequency band (0.15 to 0.50 Hz) of the LF are integrated by the power density of each frequency band / RTI > The LF / HF ratio is calculated using the power of each band (S701). Here, HF power reflects parasympathetic activity, and LF power reflects sympathetic activity mainly with parasympathetic component. The LF / HF ratio is generally regarded as an index of the sympathovagal balance.

It is determined whether the calculated LF / HF ratio is within the range of the REM sleep band (S702). At this time, if it is in the REM sleep band range, the EOG signal frequency or the power spectrum density is calculated (S703), and it is determined whether the calculated LF / HF ratio is in the REM sleep band range (S704). At this time, if it is included in the REM sleep band range, it is determined to be the REM sleep phase (S711). Otherwise, it is determined whether it is larger or smaller than the upper limit value of the REM sleep band (S705). If the LF / HF ratio is greater than the upper limit value of the REM sleep band, it is determined to be awakening step (S710). Otherwise, it is determined whether the LF / HF ratio exists in the shallow sleep band range (S706). At this time, if the LF / HF ratio exists in the shallow sleeping step range, it is determined to be a shallow sleeping step (S709). Otherwise, it is determined whether there is a deep sleeping range (S707). At this time, if the LF / HF ratio is in the deep sleeping step range, it is determined to be a deep sleeping step (S708). Otherwise, the user determines that there is an emergency occurrence of a risk of an acute cardiac arrest (S712).

After the sleep phase analysis is completed, the sleep data for each step may be stored in the memory 190, and the sleep data of the user may be monitored through the control terminal 30 after awakening. The control unit 30 also transmits sleeping data in real time to the control terminal 30 through the communication unit 180 and transmits the sleeping data to the sleep management center 40 through a wired or wireless communication network.

FIG. 6 is a flowchart of an embodiment of a sleep state analysis method for sleep control according to the present invention.

As shown in FIG. 6, the sleep state analyzing unit 220 may be a sleep state analyzer that detects sleep / sleep apnea, snoring, body movement, and the like, which are important obstacles to sleep that degrade the quality of sleep until the user is awakened And the data can be used to provide real time sleep posture correction and sleep guidance so that the user can take good quality sleep.

During sleep apnea, the airway is blocked, the flow of air is eliminated, the heart and lungs try to breathe, and then the throat becomes fully stretched and becomes apnea. As a result, oxygen is lacking in the body and hypoxia appears. Hypoxia induces myocardial infarction, hypertension, and stroke.

Clinically, apnea refers to a reduction in at least 80% of the normal respiratory volume in the sleep polyp test, lasting more than 10 seconds, and a reduction in oxygen saturation by more than 3%. Hypopnea refers to a decrease in respiration by more than 50%, lasting more than 10 seconds, and a decrease in oxygen saturation by more than 3%. Apnea-Hypopnea index or respiratory disturbance index is defined as the number of apneas or hypopneas per hour during sleep that is greater than 5 and is associated with excessive daytime sleepiness or insomnia. Sleep apnea is diagnosed. If you have 20 breaths or more, you can suddenly die.

Since respiration changes the peripheral circulation, it is possible to extract from the PPG signal measured by the PPG sensor module 110 in contact with the user's forehead. That is, the respiration signal is detected by connecting each valley point of the PPG signal.

After the PPG signal processing, the respiration signal extraction algorithm (S721) first filters the collected PPG signal to extract only the part related to respiration. The filtering method includes a low-pass filter, a high-pass filter, and a band-pass filter. The types of filters include a vessel filter, a butter word filter, and a Chebyshev filter. have. When the extracted respiration signal is converted into the frequency band through FFT analysis, the respiration rate period can be measured. From this, the user can determine whether there is a low breathing or apnea symptom during sleep (S722).

7 is a flowchart of an embodiment of the sleeping / sleep apnea determination algorithm of FIG.

As shown in FIG. 7, when the portable monocycle mask 10 is worn, the presence / absence sensor module 150 operates to inform the user of the start of sleep (S731). It is determined whether the respiration amount has decreased by 50% or more as compared with before the sleeping (S732). If the determination result is not less than 50%, it is determined to be normal (S733), and if it is decreased by 50% or more, it is determined whether it is decreased by 80% or more (S734). If the breathing amount is not decreased by 80% or more, it is determined that the time is less than 10 seconds. If the breathing amount is not more than 80%, it is determined that the breathing is normal (S738) (S729). If the breathing amount is decreased by 80% or more, it is determined that the time is less than 10 seconds, the sleeping apnea data is stored (S742), and the snoring prevention pillow control unit is operated (S729) ). Next, it is determined whether the sum of the number of times of sleep / apnea of breathing (respiratory disturbance index) is greater than 5 or not (S740). At this time, if it is 5 or more, it is judged to be sleep apnea (S741), and the sleep apnea data is stored (S742). Based on the result of the sleeping / apnea determination, the corkork preventive pillow controller 20 is operated to adjust the sleep of the user.

Referring to FIG. 6, in the sleep state analysis method for controlling sleep, snoring will be described. Snoring is the sound of air as it passes through the nose and vibrate the soft tissues during breathing during sleep. Snoring is a kind of disease in which the neck shakes when the neck or an abnormality is in the neck. Snoring is a symptom in which the tension of the muscles such as the tongue and the nape of the stomach is released to partially block the airway, and the flow of air is disturbed when sleeping. Snoring is the sound of breathing through your nostrils through your nostrils, and the causes of snoring are age, obesity, and drinking. Snoring is accompanied by obstructive sleep apnea, although only part of the airway is blocked. Snoring can be reduced by 50 to 70% with habit of sleeping on the side. If you sleep on your side, your breathing path will not be pressed, you will be able to reduce your snoring, and your pillow should be level with your forearm height.

Accordingly, in the present invention, snoring detection is performed by providing the corkel sensor module 130 on which a piezoelectric sensor or a microphone is mounted on a nose portion of the portable monospore mask 10. When the size of the snoring is greater than the reference level, it is judged that the snoring is performed, and the snoring detection algorithm determines the total number of snoring and the number of the snoring by the snoring detection algorithm The snore data such as the time and the average number and time of the snort per hour, the number and the time of the intermittent snoring are extracted (S724). The extracted snoring data is stored (190), and the corko preventive pillow control unit 20 is operated to adjust the sleep of the user based on the snoring data.

In addition, with reference to FIGS. 2 and 6, the body motion detection method will be described in the sleep state analysis method for controlling sleep. In general, it is known that when the quality of sleep is low, the amount of body movement is small, and when the sleeping surface is bad, the amount of body movement is increased. Thus, the quality of sleep can be evaluated from the body movement amount.

In the present invention, the body motion detection is performed by providing the body motion sensor module 140 equipped with the piezoelectric sensor or the on / off sensor mounted on the left and right and rear lobes of the portable monospore mask 10. A signal processing for shaping the body motion signal obtained by the body motion sensor module 140 so that the processor 200 can recognize the body motion signal is performed (725). When the user wears the portable monocycle mask 10 and looks up at the ceiling, when the user lies downright, the body movement detection sensor 650b mounted on the rear side, the body movement detection signal 650b, When the user is lying to the left and right sides, the left and right lying signals are generated together with the ID code at the left and right side bodily sensation sensors 650a and 650c (S726). These signals are passed to the process to remember the state. In this procedure, the number of times of consent and the number of times of maintenance are recorded and used as data for evaluating the quality of the user's sleep.

Referring to FIGS. 1 and 6, the snoring prevention pillow controller will be described in detail in order to adjust the sleep level.

The snoring prevention pillow to be used incidentally in the present invention further includes a function of freely adjusting the height of the snout, and a function of applying a vibration stimulus to the user with the vibration motor.

When the sleep phase analyzer 210 detects an acute cardiac arrest as a result of the sleep / apnea determination (S712), the snoring prevention pillow controller 20 operates to operate the vibration motor attached to the pillow, (21), which act to cause alternating high-altitude movements. At this time, if the LF / HF ratio does not increase for 1 minute, it is recognized as an emergency. When such an emergency occurs, the emergency signal is transmitted to the sleep management center 40 via the control terminal 30, and when it is determined that the emergency is occurred, the local emergency management center can request assistance.

When the sleep state analyzer 220 determines that the sleeping state of the user is sleeping / sleep apnea, the snoring prevention pillow controller 20 operates to cause the left and right heights of the pillow to alternately change, (22).

When the sleep state analyzer 220 determines that the user's sleep state is a state of nose snoring, the snoring prevention pillow controller 20 sends a signal to the sleeping pillow so that the user's neck is 6 cm, the shoulder is 2 cm (22), the left or right side of the sleeping pillow swells so that it can be tilted sideways by about 30 °. In other words, snoring can be prevented by detecting the snoring and adjusting the height of the sleeping pillow to change the sleeping posture of the user. At this time, the sleeping pillow swells until the bodily-motion sensor module 140 mounted on the right and left of the portable monospore mask 10 is operated. When the user snoring is stopped and the bodily-depressed sleeping pillow is returned to its original state Return.

1, the sleep inducing unit 230 is operated by the wear presence / absence sensor module 150 provided on both sides of the forehead of the portable monospore mask 10 when the user wears the portable face mask 10 Is activated, and assists the user in easily entering the sleep state.

In the present invention, a biofeedback method using sound, image, and brain wave tuning is used to induce user's sleeping.

The purpose of inducing sleep by using sound is as follows. Studies on the effects of music on brain waves suggest that authentic music induces a high awareness of users to reduce awakening, stabilize their mind and generate a large number of alpha waves in the brain. When the EEG becomes an alpha wave, the mind is stabilized, stress is relieved, capacity is increased, memory is improved, concentration is increased, intuition and inspiration come to mind.

Therefore, while the user is listening to meditation music, the EEG occurs in the order of ALPA, THETA, and DELTA, so that it can have the same effect as meditation.

The types of sleep induction sound include classical music, New Age music, Korean music, Indian meditation music, Chinese Tibetan music, sound of waves such as waves and birds and rains, shamans' drums and songs, hymns, Etc. may be used.

In the present invention, the sleep induction sound may be pre-stored in the memory 190 or may be a sleep application of the control terminal 30 using a mobile multimedia phone such as a smart phone. In addition, the type and order of the induction sound to be used during sleep are selected in the control input setting unit 320 of the control terminal 30.

The purpose of inducing sleep using images is described below. Between sight and light, one needs to be able to adapt to the given environment as one of human adaptability. There are two types of adaptation related to the brightness of light: light and dark. Generally, it takes about 30 minutes to change from myeongseong to dark adaptation. On the other hand, when you go out to the bright place in dark place, the adaptation time is very short, about 200 ms. However, as the age increases, the eyes of elderly people feel the light and the sensitivity of the responsive photoreceptor decreases, and the sensitivity of the cones and lobes corresponding to the quantitative changes of light declines with age, The adaptability to the object is reduced and it becomes difficult to view the object in a dark place.

Accordingly, in the present invention, when the portable visual mask 10 is worn, it is temporarily exposed to darkness, thereby relieving the anxiety and fear experienced by the user, and presenting a light or image in which light intensity is gradually reduced during the dark time.

As a preferred embodiment, at a color temperature of 3,000 K, the illuminance is gradually lowered from 5 lux to 3 lux and then turned off after 20 to 30 minutes, or light of one lux is maintained during the sleeping. The light is attenuated by 98 to 99.7% by the eyelid by the human eyelid, and the most blurry light condition (1 lux) represents the effective retinal illumination of 0.0003 to 0.002 lux.

In addition, images such as an evening glow or a night sky can be presented, which are suitable for inducing sleep stability inducing the mind. It is possible to shorten the time of the face by promoting the secretion of melatonin from the pineal gland of the brain by adjusting the comfortable image or the sweet lightness for the user's stress relieving and mental and physical relaxation. The illuminance for inducing the sleep and the type of the image are set by the input control setting unit 320 of the control terminal 30.

EEG synchronization is a principle that artificially induces EEG using resonance or synchronization phenomenon. That is, it synchronizes the user's brain waves to the sound and the flashing light.

The purpose of inducing sleep by using EEG synchronization is as follows. A binaural beat is a typical example of synchronizing brain waves by auditory stimulation. In other words, if you want to synchronize the brain wave to the alpha wave (7 ~ 13Hz) for concentration and stress relief, you will hear 310Hz for one ear and 300Hz for the other ear. Then, a sound component of 10 Hz, which is a difference component of the two frequencies, is applied to the auditory stimulus, and the user's brain waves are synchronized with the sound to generate the alpha waves predominantly. If you want to meditate, settapa (4 to 7Hz), if you want to get into deep sleep, you can listen to different frequency sounds to be synchronized to the delpha (<4Hz).

In order to synchronize brain waves by visual stimulation, a similar conventional technique generally blinks the blue or red LED to match the desired brain wave tuning frequency. However, there is a possibility that blue may cause a side effect of delaying or advancing the sleep-wake rhythm by the light stimulating effect, and there is a fear that red is awakened rather than calming the user according to the color psychology.

Accordingly, in the present invention, when the LED is used, the yellow or orange LED is blinked to facilitate the EEG tuning. When the OLED display is used, the yellow or orange circular area corresponding to about 20 to 30% Synchronize the EEG.

In the present invention, when sleep induction is performed using the EEG, the auditory and visual stimulation algorithms may be stored in the memory 190 in advance, or may be stored in the memory 190 using the control terminal 30 ) Can be a sleeping application. In addition, the type and order of the induction light and image to be used during sleep are selected in the control input setting unit 320 of the control terminal 30.

8 is a flowchart of an embodiment of a sleep induction method for controlling sleep according to the present invention.

In the present invention, the PPI is calculated from the reflection type PPG photoelectric sensor located above the eye lid of the portable monospore mask 10, and the PRV is calculated therefrom. Then, the LF / HF- ratio is calculated, The bio-feedback method is used to compare the pre-computed value with the current value and to reduce the time of the facial expression by changing the image and the sound or the visual stimulus and auditory stimulus in accordance with the user's preset order according to the increase or decrease.

As shown in FIG. 8, first, the user inputs a sleep induction method of sound / image or brain wave synchronism in the control input setting unit 320 of the control terminal 30 and three sequential tracks to be progressed according to each sleep induction method (S751, S752). A biofeedback type sleep induction is started from when the user wears the portable mask mask 10. The LF / FH-ratio calculated in the sleep phase analyzer 210 is calculated every 3 minutes (S755). If the value of the currently calculated LF / FH-ratio is greater than the value of the previous LF / FH-ratio, proceed to the next track, and if so, compare with the upper limit of the LF / HF-ratio of the shallow water (S756). If the value of the LF / HF-ratio is greater than the upper limit of the LF / HF-ratio, the next track is processed. If the value of the LF / HF-ratio is equal to or smaller than the upper limit of the LF / HF-ratio, the biofeedback is completed (S757). The time taken up to this time is stored in the memory 190 as the user's entrance time (S758). In addition, if the user continuously selects the image / sound holding during the sleep maintenance in the control input setting unit 320, the selected image / sound is presented to the sleeping user (S759). However, if EEG synchronization is selected, the visual and auditory stimulation tracks are automatically determined in the order of alpha tuning, theta tuning, and delta tuning.

In the prior art, sound / image is presented unilaterally or the EEG is tuned without considering the characteristics of the user. On the other hand, the present invention provides a sound / image or a brain wave tuning suitable for a user's characteristic by inducing sleep by the bio-feedback system as described above, so that a user can take a comfortable and comfortable sleep, .

Hereinafter, a description will be given of the awakening of the user by the awakening induction method in the present invention. Normal adult day sleep consists of shallow water → deep sleep → REM sleep → shallow sleep phase sequentially in 7.5-8 hours and 90 minutes in a cycle and repeats 4 ~ 5 cycles in one night.

Among these sleep stages, the most refreshing sleep phase is the shallow sleep phase. This is the stage where you are likely to fall asleep, the step you do not know whether you are asleep or not, If you wake up while you are dreaming, the contents of your dreams will remain in your head so you can feel like you are still dreaming, so that the contents of your dreams will haunt your head for a while, I feel very annoyed and tired because I am forced to sleep.

Therefore, one preferred embodiment of the awakening induction method according to the present invention is to detect a REM sleeping phase that can be most clearly distinguished among the sleeping phases, and to detect sound and images that gradually increase after the REM sleeping time per each sleeping cycle It features a way of presenting and waking up to the user.

FIG. 9 is a time chart of an embodiment for explaining a method of inducing a vapor for sleep control according to the present invention.

Referring to FIG. 9, the awakening inducing unit 240 will be described in detail. First, the control input setting unit 320 of the control terminal 30 selects a scheduled time to be woken up. Five types of the scheduled weather can be selected. That is, it is after 1 hour and 30 minutes, 3 hours and 14 minutes, 4 hours and 51 minutes, 6 hours and 28 minutes, and 8 hours and 5 minutes after the start of sleep. Next, the control input setting unit 320 selects the weather music and the vapor light source, and selects the minimum and maximum volume and light amount. The meteorological music selects light music that is effective for activating sympathetic nerves, and the vapor light source selects red or white. When the setting is completed and the wearer wears the portable mask mask 10, sleep initiation is started. After the start of the water surface, the musical instrument and the light source are enlarged and brightened in five steps every two minutes when the scheduled time comes.

In the present invention, the lucid dream inducing unit 250 induces a user to induce a lucid dream by inducing the user to the subjective REM sleep at the REM sleep of the visa, and the lucid dream is induced as follows.

In 1913, the Dutch physician F.V. This is the first term Eden used. It is characterized by the ability to control the contents of a dream to a certain extent because it recognizes the fact itself by dreaming. It is more realistic and consistent than the content of a dream that is not aware of it. There is little difference between a sleeping state and a waking state because it can be thought and remembered as when awake while dreaming. Through lucid dreaming, we get to know the symbols of the so-called unconscious and understand it to solve their psychological problems and gain new energy in life.

Accordingly, in one embodiment of the present invention, the sleep phase analyzer 210 detects REM sleep and applies a red flashing light source to a dreaming user. At this time, the blinking light source can mount the red chip LEDs on the inside of the eye lid part of the portable monospore mask 10 by five right and left or present the light to the user in a fractal pattern on the OLED display. In the control input setting unit 320, the illuminance of the red LED array or the OLED display may be set to three levels and the repetition time may be set to five levels. In addition, the lighting start time can be set by the control input setting unit 320 in five steps. The step of the lighting start time corresponds to the order of the REM sleeping state while the user is sleeping. The user can select the use of sound to maximize the effect of the lucid dreaming.
