Description

  The present invention relates to a mental health / breathing training system used for self-training and guidance in mental health and breathing method training by feedback of biological signals such as breathing, heartbeat, brain waves, etc. during zazen, yoga, meditation, supine etc. The present invention relates to a surface-emitting display body.

  In recent years, the importance of mental health care has been screamed as the number of people suffering from mental stress such as stress and worries in social life, fear and misfortune due to war and disaster, insomnia due to guilt, depression, lethargy, etc.

  In addition, stress breaks the balance of autonomic sympathetic and parasympathetic tone, and induces various diseases. Therefore, it is important to release stress and not to store it, and perform zazen and yoga in a space that is not disturbed by others, listen to healing music, etc., open your mind and relax your mind And refreshing is done.

  In addition, the function of the respiratory organs has declined due to chronic obstructive pulmonary disease due to aging, and an increasing number of people need shortness of breath and oxygen inhalation. Therefore, there is a need for a respiratory rehabilitation method that can prevent respiratory deterioration and that can be enjoyed by the elderly.

Also, when playing sports or giving lectures in front of a large number of people, taking a deep breath is often used in order to maintain their concentration for a long time without failing to improve their ability.
If you take a deep breath with abdominal breathing, parasympathetic nerves will dominate, your pulse and blood pressure will fall, and you will be released from stress. Yoga meditation is said to increase the alpha wave of the brain waves, increasing concentration and freeing you from worries and stress.

  Therefore, the breathing speed and interval of subjects such as zazen, supine zen, and meditation, changes in the intensity and location of brain waves (there are α waves, β waves, and θ waves depending on the frequency), heart rate intervals, body temperature, blood oxygen concentration, etc. If you can visualize changes in your body's biological signals and feed back to your subjects, you can easily and objectively grasp your body and mental condition, and you can effectively concentrate and relax.

In addition, if you can record the breathing method and biological signal status of advanced zazen and yoga people, and reproduce and visualize the state, it is possible to train and imitate the breathing method and brain wave status of advanced people and improve effectively. It is done.
Furthermore, there was also a demand to relieve insomnia caused by trouble and stress, freed from the trapped heart by arranging the breath.

  In order to meet such needs, for example, Patent Literature 1 discloses a device that turns on a level indicator of an LED lamp with a timer and adjusts a breathing timing for training. However, there is no description about monitoring actual breathing and heartbeats with sensors and displaying and recording the status with lamps. Therefore, it was not possible to grasp the achievement level of breathing training.

In addition, since the display device is a level indicator of a bare point-emitting LED lamp, the display device itself has low design, and the user cannot concentrate on light without feeling vitality (life force). It could not be said that it was suitable as an object to continue to watch.
On the other hand, with the progress of brain science in recent years, the relationship between brain waves and the degree of concentration and meditation has been elucidated, and it has become possible to control machines with brain waves.

  Devices for analyzing brain waves and using them for mental health control training are also commercially available from Neurosky. In addition, Heartmas has developed a device that displays the state of the autonomic nerve from the rhythm of the pulse cycle measured with the blood flow of the finger as a three-step LED color change and a graph on the computer screen, which is useful for mental feedback training by breathing. Sold.

  Also, an electrocardiogram waveform is measured by a wearable sensor or the like, and the period variation between adjacent R waves of the electrocardiogram (the waveform of the electrocardiogram when the heart contracts) and the pulse pulsation interval are Poincare plots (variation of the pulse period) (Also referred to as Lorentz plot), and attempts have been made to visualize and visualize changes in the mental surface of relaxation and tension (see Non-Patent Document 1 and Patent Document 2-12). ).

  However, if the display unit is a three-stage LED color change display, a graph display on a liquid crystal display screen, or a bar display with an LED, it cannot be felt that it is suitable for concentrating on the light of the display device. I couldn't keep on staring while maintaining my power, and I couldn't get enough feedback because I couldn't see the graph in half-eye or meditation.

Furthermore, in the case of a device used in a meditation or meditation party where a large number of zazen and meditation people gather, a small LED display or a device using a liquid crystal display with large angular dependence and large luminance unevenness will cause a large number of zazen There was a problem that it was difficult to teach because of poor visibility when instructing other people and meditators.
As an example of such a poorly visible liquid crystal display device, for example, a display formed of a dot matrix used in a smartphone, a tablet computer, a personal computer, a television, etc., and a distance of about 30 cm to 1 m is placed from the subject. Examples include liquid crystal displays that are used.
These liquid crystal displays are dot matrix displays with LED backlights and are excellent for displaying various characters and designs. In general, however, the peak brightness when emitting white light is often less than a few hundred cd / m ^2, and you feel the power of light when you are in zazen, supine, meditation, or when you close your eyelids lightly. Is not enough.

Further, when a display with rough pixels is viewed at a short distance, the dots of the pixels are conspicuous, and when an image such as a moon or a lotus flower is displayed, it is impossible to obtain a real feeling, a real feeling, and a vitality.
In addition, in liquid crystal displays, in low-light rooms and bedrooms, the contrast of the black display part due to light leakage from the backlight and the luminance unevenness due to the viewing angle are conspicuous, and the display itself and the images of characters and pictures displayed on the display It is totally unsuitable as a target to focus on.

  Further, there is a dispersive EL sheet as a surface emitting display similar to an organic EL sheet. Dispersion type EL sheet consists of a light emitting layer sheet in which an inorganic phosphor powder such as zinc sulfide having a diameter of several tens of μm is dispersed in a high dielectric constant binder, and a titanium sheet in a high dielectric constant binder. This is a structure in which a dielectric layer sheet in which an ink in which a high dielectric constant dielectric powder such as barium oxide or strontium titanate is dispersed is applied to an aluminum foil electrode is heat-pressed and laminated with a moisture-proof film.

The dispersion type EL sheet is driven by applying an AC high voltage of about 100 to 400 V and several hundred to several KHz. In a phosphor made of an inorganic semiconductor, electrons and holes are generated by the generated hot electrons, and after being captured at a donor level and an acceptor level, recombination or light is emitted by energy transfer to another emission center. Alternatively, light is emitted by direct collision excitation of a light emission center such as Mn ion in the inorganic semiconductor phosphor. However, the maximum brightness is about several tens to several hundreds cd / m ^2, which is one to two orders of magnitude lower than the organic EL sheet. Further, acoustic noise is generated by AC driving, which hinders mental concentration in a quiet place, and is not suitable as a surface emitting display of the present invention.

<Mental health and breathing training system>
A configuration example of the mental health / breathing training system of the present invention is shown in FIG. In FIG. 1, m, n, p, s, and t are integers that satisfy s + m ≧ 1, n ≧ 1, p ≧ 0, and t ≧ 0.

A device that dissipates. Arrows indicate the flow of data.

(Biosignal sensor)
The biological signal sensor is a sensor for acquiring biological signals such as a subject's breathing speed / interval, brain wave, heartbeat interval (pulse) body temperature, blood pressure, blood oxygen concentration, and may be contact type or non-contact type. S biological signal sensors 2 for wired connection and biological signal sensors 2 ′ for wireless connection including m wireless transmission devices 3 are provided for acquiring biological signals of the subject 1.
Here, the plurality of biological signal sensors 2 and the biological signal sensor 2 ′ are referred to as a biological signal sensor group, and the plurality of surface light emitting display bodies 8 are referred to as a surface light emitting display body group. For convenience, even in the case of one unit, it may be referred to as a biological signal sensor group or a surface emitting display group.
The biological signal sensors 2 and 2 ′ may include a preamplifier that amplifies the acquired signal. Biological signals obtained by these sensors are connected via a universal serial bus (USB) for wired communication, and wireless LAN, Bluetooth, infrared communication, etc. connected to the sensor for wireless transmission. The biological signal is input to the reception device 4 through the transmission device 3. The sent signal is subjected to arithmetic processing by the arithmetic processing unit 5 and is sequentially stored in the data storage / reproduction device 6.

(Biosignal input / receiver)
The biological signal input / reception device 4 has a function of receiving a biological signal transmitted from the biological signal sensors 2, 2 ′ and transmitting it to the arithmetic processing device 5. Can be processed.

(Arithmetic processing unit)
The arithmetic processing unit 5 stores in the data storage / reproduction device 6 signal data based on a calculation result obtained by performing a calculation process using a biological signal input and a biological signal transmitted from the receiving device 4 and a biological signal by a preset method. And a function of sending the saved signal data to the drive circuit 7 of the surface light emitting display 8 and driving the surface light emitting display unit 9 and the sub display unit 10. Moreover, it also has a function as a control device of the mental health / breathing training system 100 of the present invention, and controls the biological signal input, the receiving device 4, the data storage / reproducing device 6, the external communication device 11, and the like. The subject also has a function of inputting information.

  For the measured biological signal data, a digital signal processor in the arithmetic processing unit 5 or a commercially available smartphone, tablet terminal, personal computer, or the like is used as the arithmetic processing unit 5 to calculate values or calculation values serving as various indexes.

  For example, the biological signal obtained by the microwave Doppler sensor is subjected to frequency analysis by Fourier expansion, and the signals are separated into frequencies peculiar to breathing and pulse. You can know the speed, interval, and other conditions.

  Breathing is slow and deep abdominal breathing when relaxing, and the pulse is lower than normal. On the other hand, during stress, breathing is quick and shallow, and chest breathing occurs, and the pulse and heart rate increase from normal.

(Surface emitting display)
In the surface emitting display 8, the driving circuit 7 receives a signal sent from the arithmetic processing unit 5, and the surface emitting display unit 9 is driven by the driving circuit 7 and displayed. Information is also displayed on the sub display unit 10.
A signal is sent from the arithmetic processing unit 5 to the drive circuit 7 of the n number of surface emitting display bodies 8 to control and display the light emission state of the surface emitting display unit 9.
The drive circuit 7 may be included in the housing of the surface light emitting display 8 or may be externally attached.
The surface light emitting display 8 includes a surface light emitting display unit 9 occupying a main area, and may include a sub display unit 10 for data display. The shape of the surface light emitting display unit 9 used in the present invention can be a polygonal shape such as a quadrangle and an octagon in addition to a circle and an ellipse, and a shape obtained by combining these shapes or an arbitrary shape may be used. A circle symbolizing the glory of the moon or Buddha can be preferably used.
The surface light emitting display unit 9 may have a light diffusing surface or a mirror surface, and the light diffusing surface and the mirror surface may be mixed.

  The size of the surface-emitting display unit 9 is preferably the size of the surface-emitting display unit 9 that can secure a viewing angle that can recognize that the surface emitting is based on the distance to the subject, and preferably the viewing angle of the full moon. Corresponding 0.5 degree or more, more preferably 5 degree to 30 degree. Below 0.4 degrees, the viewing angle is small and it becomes difficult to feel surface light emission, and the amount of light emission at non-dazzling luminance is reduced, so the mental impact on the subject is also reduced. When it is larger than 30 degrees, it is easy to feel pressure. On the other hand, when the diameter is larger than 40 cm, the power consumption increases and the manufacturing cost becomes high.

In a specific example of use, it is desirable to use a circular surface-emitting display body having an area of 7 cm ² or more at a distance of 20 cm or more from the subject. For example, a diameter of 1.5 cm to 4 cm is suitable for incorporation into a windshield glass of a watch viewed from a distance of 20 to 30 cm, a dial or a pocket watch, and a diameter of 3 cm to 6 cm is suitable for incorporation into a cover of a smartphone. When installed in a cover or alarm clock of a tablet PC that is viewed at a distance of 30 cm or more, it is 5 cm to 10 cm in diameter, and a hanging shaft or screen that is separated by 60 cm or more. When viewing from above, or when attached to the ceiling of the bedroom or hanging down and looking up from the bed or floor, a size of 20 to 40 cm in diameter is appropriate.

Further, the maximum luminance of the surface light emitting display unit 9 is suitably 1500 cd / m ² or more, and more preferably depends on the distance between the subject and the surface light emitting surface 8, but if the distance is 60 cm or more, 3000 cd / m ² or more and 6000 cd / m ^2. It is more preferable to use a surface light emitter that can emit light with a luminance of about ² or less. When it is less than 1500 cd / m ² , it is difficult to feel the power of light. When the brightness is higher than 6000 cd / m ² , the pupil is opened in a dark place, so that the distance is 1 m or less and the eyes are dazzled and fatigued.
Further, when the surface light emitting display unit 9 emits white light, it is desirable for the eyes to have a broad spectrum that does not include a strong emission line spectrum but includes a light emission region from 450 nm to 700 nm or more.
The light emission color of the surface light emitting display unit 9 of the surface light emitting display body 8 is gentle to the eyes in the range of white, yellow, or yellowish orange on the xy chromaticity diagram of the CIE (International Lighting Commission) -XYZ color system. Therefore, it is desirable that the color temperature is 2000 K or more and less than 6000 K, more preferably 2000 K or more and 4000 K or less, and still more preferably 2000 K or more and 3500 K or less. Red light having a wavelength is desirable because it is considered to have high transmittance.

  A light source most suitable for the surface emitting display unit 9 is an organic EL sheet. The organic EL sheet is a self-luminous thin sheet light source that utilizes the electroluminescence (abbreviated as EL) phenomenon of organic light-emitting materials. It does not contain harmful ultraviolet rays or infrared rays, and it feels warm and gentle to the eyes. The surface emitting display unit 9 of the display body 8 can be desirably used.

As another suitable surface emitting display body 8 other than the organic EL sheet, a backlight unit having a built-in inorganic white LED or the like whose surface is non-glossy and subjected to low reflection light diffusibility treatment can also be used.
However, a normal white LED converts part of the light of the blue LED with a yellow phosphor. For this reason, a strong blue emission line emission spectrum is included in the vicinity of a wavelength of 450 nm, and there is a risk of damaging the eyes if it is viewed for a long time. For this reason, when using a surface emitting display using LEDs, a warm white LED whose intensity of the bright line peak from purple to blue, which is about 400 nm to 460 nm, is lower than the intensity of the peak of the light emission component from green to red is used. It is desirable to use it.

In addition, the surface emitting display panel with a built-in LED made by arranging individual LED packages on a substrate is likely to cause color unevenness and brightness unevenness, and it is difficult to make a flexible LED panel. When incorporating, it becomes difficult to wind.
However, by using a light diffusion sheet, a microlens array sheet, a microprism array sheet, and the like on a light guide plate sheet with an LED edge light source, glare can be suppressed and flexibility can be achieved. In that case, although it becomes thicker than the case where the organic EL sheet is used, it is possible to realize the appropriate luminance and luminance and distribution similar to those of the organic EL sheet, and as the surface light emitting display body 8 in the mental health / breathing training system of the present invention. It can also be used.

In addition, since dimming of the LED has a sharp current-voltage characteristic, ON / OFF pulse width control is often performed, causing flickering. Since the organic EL sheet has a gentler current-voltage characteristic than inorganic LEDs, dimming control is simple, and gradation control by an inexpensive voltage adjusting device or current adjusting device is easy. From about 1000 cd / cm ² to 6000 cd / The light can be smoothly adjusted to a brightness of about cm ² and a gentle warm white light emission with a color temperature of about 3000K can be obtained.
Therefore, it is not dazzling even when looking directly at the surface light emitting display 9, it can be adjusted to the optimal brightness to feel the power of light even in the state of zazen, supine Zen, half-eye or lightly closed meditation, and changes in light emission High healing effects can also be obtained by fluctuations.

(Organic EL sheet for surface-emitting display)
Next, the organic EL sheet that can be preferably used as the surface light emitting display of the present invention will be described in more detail.
The organic EL sheet uses a light-transmitting substrate, and it is possible to use an element having a bottom emission structure that extracts EL light emission from the substrate side and a top emission structure that transmits EL light emission from an electrode opposite to the substrate. An example of the structure of a bottom emission element used for a general organic EL sheet is shown in FIG. 13, and an example of the manufacturing method will be described below.

  First, the substrate 14 is made of glass or a light-transmitting substrate such as a flexible plastic film or sheet having a water vapor or oxygen barrier film formed on the surface. When a substrate made of a flexible plastic film is used, it can be repeatedly wound like a hanging shaft. Even if it is a glass substrate, when the thickness of a glass substrate is about 0.05 mm thickness, the flexibility which can be bent with a curvature radius of about several cm in diameter can be provided. In the case of an element having a top emission structure, an insulating film can be formed on a stainless steel foil.

  A bus electrode made of a metal film such as a slit shape or a mesh shape or a nano wire is formed on the substrate 14 as necessary to reduce resistance, and then a sputtered film of ITO (indium tin composite oxide) or PEDOT: A transparent anode 15 made of a coating film of a conductive polymer such as PSS is formed. Next, the end portion of the electrode layer is covered with a protective film 16 as necessary, and an electrical breakdown of the element due to dielectric breakdown due to concentration of electric charges on the electrode end or etching or unevenness of the wiping end is suppressed.

  On the anode, a hole injection transport layer 17 which is an organic EL medium layer and an electron transport light emitting layer 18 are laminated by vacuum deposition or coating. The hole injection / transport layer 17 may be functionally separated into a hole injection layer and a hole transport layer and laminated. Further, the hole injection / transport layer 17 is functionally separated into three layers of a hole injection / transport layer, a hole transport layer, and an electron block layer. It can also be laminated. The electron-transporting light-emitting layer 18 may be functionally separated into a light-emitting layer and an electron-transport layer, and further laminated into four layers, a light-emitting layer, a hole blocking layer, an electron transport layer, and an electron injection layer. You can also

The light emitting substance in the light emitting layer is made of an organic fluorescent material, an organic phosphorescent material, a thermally activated delayed fluorescent (abbreviated as TADF) material, a material containing an inorganic semiconductor quantum dot, or the like.
In addition, white light emission can be a mixture of red, green, and blue light-emitting materials, a stack of red, green, and blue light-emitting layers, or a stack of blue-green and yellow light-emitting layers.

  Thus, the organic EL sheet 38 formed by mixing or laminating the light emitting layers with a concentration gradient of a plurality of light emitting materials in the light emitting layer of one unit of the organic EL element can generate holes and electrons when the driving voltage is changed. In some cases, the EL emission color can be changed by changing the recombination position of holes and electrons in the light emitting layer due to a change in the carrier balance injected into the light emitting layer.

  In addition, a multi-photon device having a metal film of 1 nm or less as an intermediate film or a charge generation layer such as a transparent conductive film between an electron injection layer and a hole injection layer between red, blue and green organic EL element units By doing so, it is also possible to obtain white light emission with high efficiency and little color change due to luminance.

  Next, a cathode 19 made of aluminum, silver, or the like is vacuum-deposited on the electron transporting light emitting layer 18, the electron transport layer (not shown) or the electron injection layer (not shown). When the cathode 19 is made light transmissive, it is formed of a metal layer having a thickness of about 10 nm or a mesh shape. In that case, a translucent organic EL sheet can be formed, and when a metal substrate such as a stainless steel foil is used, a top emission type organic EL sheet can be formed.

  Next, as a water vapor barrier, a barrier film (not shown) is formed as necessary, and the sealing sheet 20 is further adhered and sealed to obtain the sheet-like surface emitting display of the present invention.

  A light extraction sheet 21 may be attached to the light emitting surface in order to improve the light extraction efficiency, reduce the viewing angle dependency of the emitted color, prevent mirror reflection, and the like. The light extraction sheet 21 is formed by laminating a microlens array, a microprism array, a light diffusion sheet, and the like, and reduces the loss of EL light emitted inside the organic EL sheet 38 due to total reflection at the air interface, thereby improving luminous efficiency. Can be improved.

  When there is no light extraction sheet 21, the light emitting surface of the organic EL sheet 38 becomes a mirror surface reflecting the cathode when a light reflecting metal is used for the cathode 19, but the light diffusion sheet 21 is attached. In this case, the light emitting surface is a light diffusing surface, and characters or designs may be drawn or printed on the front or back surface of the light extraction sheet 21.

The organic EL sheet 38 emits light by applying a voltage of about 3 V to 10 V between the anode terminal portion 22 and the cathode terminal portion 23 so that holes and electrons are injected into the light emitting material molecules of the light emitting layer to create an excited state. When semiconductor light-emitting quantum dots are mixed or stacked in the light-emitting layer, light emission with a narrow spectrum width from the quantum dots can be obtained by carrier injection or energy transfer to the quantum dots.

From the organic EL sheet 38, to stably obtain a high-luminance light emission of about 10000 cd / ^{m 2} from 1000 cd / ^{m 2.} Further, since the organic EL sheet 38 is a self-luminous element, display with a very high contrast is possible.

  In addition, the organic EL sheet 38 may be provided with a sub-display unit 10 for displaying time and data including dot matrix display and segment display on the same substrate on which the surface emitting display unit 9 occupying a major area is formed. Yes (see FIG. 1).

  In addition, by using a surface-emitting display body in which a plurality of translucent organic EL sheets with different emission colors are stacked directly or with a space, each biological signal data such as brain wave intensity for each frequency is assigned and displayed on each organic EL sheet. By doing so, it is possible to effectively feed back the state of the subject according to the mixing condition of the luminescent colors, and it is possible to perform mental health and breathing exercise more effectively by combining the effects of the sound described above.

  Since the organic EL sheet 38 is driven by a direct current, it does not cause flicker or noise due to the drive of an alternating power line unlike a fluorescent lamp, and there is no adverse effect on the eyes caused by a heat ray like an incandescent lamp. In addition, there is a low risk of glare due to spot-like light emission like LED lighting, adverse effects on the eyes due to excessive blue light, and circadian rhythm (a physiological phenomenon that changes in a cycle of about 24 hours, also called a biological clock).

  As described above, the organic EL sheet 38 can be suitably used as a surface-emitting display used in the mental health / breathing training system of the present invention.

(Sub display)
Next, the sub display unit 10 that displays information such as the elapsed time of zazen, respiratory rate, and pulse rate will be described (see FIG. 1).
As the sub display unit, a segment type or dot matrix type EL display device made on the same substrate as the surface light emitting display unit occupying the maximum area of the surface light emitting display body is used, or an EL display device made on a different substrate Or a liquid crystal display with a backlight can be used. Various information can be displayed on the sub-display unit. For example, a timer imitating an incense stick as shown in FIG. Here, 3 × 17 segments are displayed in a slender form, and the segments in the three rows are displayed in red from the top in order of time, and the tip of the incense stick is lit, and the green segments in the rows on both sides are emitted. Shows an example in which a state where the incense sticks are shortened with time is displayed as a display that is sequentially turned off with time from the top. Before starting breathing exercises, the incense stick is not lit as shown on the left. When training is started, as shown in the second from the left, the segment at the top end of the three rows is displayed in red. Incense sticks become shorter with time. The second from the right shows the state after 21 minutes, and the rightmost shows the state after 45 minutes. The incense stick is about to burn out, leaving one more piece. When the preset time elapses in this way, the incense stick burns out and informs the end of training. While such a display is displayed on the sub display unit, it is possible to emit a scent of incense or incense from the aroma generator 13 such as the aroma lamp or diffuser shown in FIG. It is. A plurality of sub display units may be provided.

  Next, FIG. 3 shows an example viewed from the light emitting surface of the surface light emitting display 8 used in the present invention.

The surface light emitting display 8 shown in FIG. 3A has a circular surface light emitting display portion 9 that occupies a main light emitting area on a rectangular substrate, and has a small area on the same substrate. A display unit 10 is formed. When the arithmetic processing unit is externally attached, a control signal is supplied from the external arithmetic processing unit to the drive circuit in which the surface light emitting display unit 9 and the sub display unit 10 are built in via the connector connection unit 35. Further, the power may be supplied from an external power source through a connector (not shown), or the surface light emitting display 8 itself may have a battery.

  3B has a quadrangular surface-emitting display portion 9 using a square-shaped substrate, and the surface-emitting display body 8 in FIG. 3C has an octagonal shape. In the case of having a circular surface-emitting display unit 9 using an outer substrate, both are examples in which the sub display unit is not formed on the same substrate, and a commercially available organic EL panel or a flexible sheet is used. it can.

As shown in FIGS. 3B and 3C, when a panel or sheet in which the sub display unit is not formed on the same substrate as the surface light emitting display unit 9 is used, a display panel for the sub display unit or A sheet can be prepared separately, and a case can be provided and incorporated in the surface light emitting display body 8.
In addition, it is desirable that display or non-display can be selected in the case of the light-emitting sub-display unit 10 so that it can concentrate only on the light emission of the surface light emitter during zazen or meditation.

  These surface-emitting displays 8 and mental health and breathing training systems can be incorporated into watches, wall surfaces, foreheads, ceiling boards, screens, hanging axes, doors and walls, mirrors, shrines, Buddhist altars, smartphone and tablet computer covers, etc. it can.

(Save / play / output audio)
Furthermore, a music file in mp3 format or the like stored in a smartphone or a portable music player through the external communication device 11 is stored in the data storage / playback device 6, and an audio output device including an amplifier, a speaker, an equalizer, and the like through the external communication device 11 12 can also be output (see FIG. 1). Depending on the sound of water, waves, wind, shakuhachi, whistle, etc. that have high healing effect, other statements, healing music, singing voices including overtones such as homy, and biological signals obtained from biological signal sensors 2, 2 ' The timing-controlled bells, lions, origami, singing ball hitting sound and reverberation sound of water drops are suitably used in the present invention.

In addition, the sound based on the initial data value of the subject obtained by the biological signal sensor 2 or 2 'during deep breathing or normal breathing is used as a basic sound, and the volume, resonance frequency, decay time, etc. according to the value to be induced Can be induced to the target relaxed mental state and respiratory rhythm by changing the sound from the basic sound to the subject.
It is possible to control the type and timing of the sound, frequency, decay time, reverberation, luminance of the surface emitting display, and the like which are calculated by calculating the data to be guided using the initial data for each subject according to the desired menu of the subject. Note that the menu desired by the subject can be selected by the arithmetic processing unit 5 (see FIG. 1).

Components other than the biological signal sensors 2 and 2 ′, the biological signal input, the receiving device 4, the arithmetic processing device 5, the data storage / reproducing device 6, the surface emitting display 8, the external communication device 11, the acoustic output device 12, and the aroma. The generating device 13 may be housed in one housing, or may be individually connected by wire or wirelessly.
In addition to the dedicated device, the biosignal input / reception device 4, the arithmetic processing device 5, and the data storage / reproduction device 6 can be replaced with information devices such as commercially available smartphones, tablet terminals, and personal computers.
(Data storage and playback device)
The data storage / reproduction device 6 stores data instructed to be stored by the arithmetic processing device 5 (biological signal input, signals transmitted from the receiving device 4, information input by the subject to the arithmetic processing device 5, etc.), and arithmetic processing. A function of reading out data instructed by the device 5 is provided.
The data storage / reproduction device 6 may be an internal memory in the information device or a movable external memory device such as a USB memory or an SD card.

(External communication device)
The external communication device 11 has a function of sending a signal to drive to an external device instructed by the arithmetic processing device 5. For example, sound can be output by sending a signal to the sound output device 12 shown in FIG. In addition, a fragrance can be supplied to the subject by sending a signal to the aroma generator 13.
In addition, a biological signal can be transmitted to a remote place using the Internet or the like through the external communication device 11 so that communication and guidance with a person at the remote place can be performed.

(Power supply)
The power supply device of this system is not particularly limited as long as it can supply sufficient power, although not shown in FIG. The biological signal sensors 2, 2 ′ and each device in FIG. 1 are passed through various batteries, AC adapter, wired power supply such as USB, a temperature difference power generation device attached to the surface of a human body, a fuel cell using body fluid, and the like. Power can be supplied.

(Biosignal acquisition method)
The biological signal obtained by the biological signal sensor 2, 2 ′ is input to the biological signal input / receiving device 4.
Conventionally, the movement of breathing has been measured using a belt-type load cell (a converter that senses a load such as a compressive force and a tensile force and converts it into an electric signal), but has a feeling of pressure.
Therefore, it is desirable to use a wireless system that does not restrict the movement of the subject as much as possible.
Therefore, in the mental health / breathing training system 100 of the present invention, measurement is performed in a non-contact manner using a microwave of 10.525 GHz band (for indoor use only) or 24.15 GHz band as a biological signal sensor for simultaneous measurement of respiration and pulse. It is desirable to use possible Doppler sensors.

(Doppler sensor)
Conventionally, a non-contact type Doppler sensor using a laser beam used for respiration measurement has a problem that it cannot be accurately measured because it is reflected by the clothing. However, the microwaves can pass through the clothing and reflect on the body surface, thereby making it possible to perform non-contact measurement of a signal including respiration and pulse information of a subject away from the sensor by about 2 to 3 m without directly contacting the human body.

<Measurement of electrocardiogram>
Next, a case where an electrocardiogram is measured will be described. Conventionally, the electrodes of the biological signal sensor 2 are attached to the chest, and the connection between the biological signal input and the receiving device 4 is wired, so that the body can be freely moved due to the discomfort and the thick electric wires. There was annoyance that was bound.

  In the system of the present invention, an electrocardiogram can also be obtained by measuring a change in electric potential on the surface of a human body while wearing zazen. For example, using a zazen cushion on the surface made of a conductive fiber cloth as a reference electrode, a conductive stretch wristband made of carbon fiber impregnated with a conductive polymer in the left and right arms across the heart is used as the electrode. Alternatively, a biosignal sensor 2 ′ that measures an electrocardiogram from a potential difference between the left and right electrodes is formed by attaching a ring as an electrode to the fingers of the left and right hands, and the measurement data is input wirelessly through the wireless transmission device 3 as a biosignal. , Can be sent to the receiving device 4.

<Calculation of measurement data>
Next, the processing in the arithmetic processing unit 5 will be described using the measurement data of the electrocardiogram as an example.
When the R wave interval in the electrocardiogram is detected and Lorentz plotting is performed, an elliptical scatter plot is obtained.
Here, Eleven of Kyoto University reported that individual evaluation of sympathetic / parasympathetic nerve function was obtained from short-term heart rate measurement (about 2 minutes) using Lorentz plot (J. Auton). Nerv. Syst., 62, p79-84, 1997).

The values of the major axis length (4 times the standard deviation in the direction of the symmetry axis) and the minor axis direction (4 times the standard deviation in the direction across the symmetry axis) of the ellipse in the graph obtained by the Lorentz plot are L And T.
The value of L / T, which is an index of sympathetic nerve activity, increases in the resting state, and decreases in the concentration and tension states. Further, it is known that the value of log (L × T) is an index of parasympathetic nerve activity and increases during abdominal breathing.

  Therefore, a value of L / T or log (L × T) is selected, and the light emission state of the surface light emitting display portion 9 of the surface light emitting display body 8 is proportional to the magnitude of the value according to the measurement data of the subject. By controlling so as to fluctuate in real time, the state of the subject can be visualized and can be effectively fed back.

<Measurements of various biological information>
(Pulse measurement)
The pulse can be measured from changes in blood flow. For example, an optical pulse such as a laser Doppler sensor or a pulse oximeter (a medical device that attaches a probe to a fingertip or ear and monitors the pulse rate and percutaneous arterial oxygen saturation without invasiveness) such as a fingertip, arm, or earlobe Can be measured with a sensor. A pulse sensor is mounted on the back cover side of the wristwatch-type biological signal sensor, and the measurement data can be transmitted to the biological signal input and reception device 4 wirelessly.

  Mukai et al. Of Meijo University reported that pulse and blood flow fluctuations can be observed with the earlobe, and blood flow fluctuations increase in a relaxed state (parasympathetic dominant) (Journal of Japanese Society of Physiological Anthropology, Vol. 11, No. 2, p81-) 86, 2006).

(Measurement of blood oxygen saturation)
The pulse oximeter can measure blood oxygen saturation and pulse. Blood oxygen saturation is calculated and measured from the difference in the amount of infrared absorption between hemoglobin and oxyhemoglobin at the wavelength of the infrared light-emitting diode with a finger, earlobe, nose, etc., and the pulse is calculated from the fluctuation.

  By measuring blood flow at multiple locations on the head, brain function can be measured with high accuracy and in real time. Such devices include the near infrared light imaging device “NIRStation” manufactured by Shimadzu Corporation, the wearable optical topography device “WOT-220” manufactured by Hitachi, Ltd., and the head near infrared light measuring device “HOT121B”. It can also be used as a set-type biological signal sensor.

(Measurement of electroencephalogram)
In addition, the electroencephalogram can be measured in a non-contact manner using a highly sensitive magnetic sensor using a magnetic impedance element (MI sensor) or an atomic magnetic sensor.

The electroencephalograms are classified according to frequency from the higher frequency as follows.
γ wave 31-64Hz Irritated state, anxious state (sympathetic nerve predominates)
β wave 14-30Hz Normal awakening α wave 8-13Hz Relaxed, concentrated (parasympathetic dominant)
Theta wave 4-7Hz Attempted state REM sleep δ wave 1-3Hz Deep sleep state Non-REM sleep

  There are two types of autonomic nerves: sympathetic nerves and parasympathetic nerves, which maintain and regulate human body functions such as metabolism, digestion and absorption, maintenance of body temperature, sleep and wake rhythm, immunity, blood circulation, and regulation of hormone balance. Yes. It is said that 70 to 80% of chronic diseases are caused by the balance of autonomic nerves.

It is known that when parasympathetic nerves are dominant, the pupil contracts, the heart rate decreases, the body temperature decreases, the respiration deepens and the respiration rate decreases, and the α wave is enhanced to be relaxed.
On the other hand, it is known that when the sympathetic nerve is dominant, the pupil is enlarged, the heart rate is increased, the body temperature is increased, the respiration becomes shallower and the number of times is increased, the γ wave is enhanced and the stress is present.
In meditation with zazen or yoga, correct and deep breathing can make the parasympathetic nerves dominant and relax and enhance alpha waves. It is known that a strong δ wave is generated during sleep after relaxation.

(Measure blood pressure)
In addition, according to a report by Takagi et al. Of Shinshu University (12th Japan Biomedical Engineering Koshinetsu Branch Nagano symposium), the Blood Bragg Grating (FBG) sensor can measure blood pressure in an unconstrained state. Can be used as a signal sensor.
When parasympathetic nerves predominate and relax, blood vessels spread and blood circulation improves and blood pressure decreases. Conversely, sympathetic nerves predominate during stress and blood pressure rises.

(Measurement of electrical conductivity)
The electrical conductivity is measured by, for example, a single rectangular pulse (abbreviated as SSVP) method.
In the SSVP method, the Seki electrode (minus pole) is placed in a total of 28 points (acupuncture points) on the left and right sides of the wells on the fingers of both hands and feet, and the indifferent electrode (plus pole) is placed on the left and right sides of the outer stake hole. The current value is measured by applying a DC voltage of 3 V and a pulse voltage of 256 μs.
The intrinsic electrical conductivity of the measurement system is expressed as a peak current value after 1 μs and is designated as BP, and BP is also related to blood flow. The post-polarization current AP is a steady-state current value that flows even after polarization in the skin basement membrane, and increases with the sympathetic nerve being dominant during stress in relation to the autonomic nerve. When relaxed, parasympathetic nerves dominate and decrease. In the present invention, the post-polarization current AP can be measured and used as a biological signal.

(Measurement of body surface temperature)
The body surface temperature can be remotely measured by a thermography device and used as a biological signal.

<Application example: Hanging mental health and breathing training system>
Next, the surface emitting display body 8 of FIG. 3A will be described in more detail by taking a hanging ring for viewing the moon or watching the character, which is incorporated in the mental health / breathing training system of the present invention.

FIG. 5 shows an example of a rear view of the hanging shaft 24 before the surface emitting display body 8 is attached, FIG. 6 shows an example of a rear view of the hanging shaft 24 after the surface emitting display body 8 is attached, and FIG. FIG. 8 shows an example of a front view of the hanging shaft 24 in the case where an organic EL sheet for illumination is used as the surface light emitting display body 8 and the sub display unit 10 is separately provided, and a broken line indicates the surface light emitting display body 8 installed on the back surface. The size and position of the sub display unit 10 are shown.
FIG. 9 shows an example of a side sectional view of the hanging shaft 24 when there is no sub display.
Further, by using a surface light emitting display 8 using a flexible organic EL sheet using a resin film as a substrate, it is possible to make a winding shaft that can be wound, and FIG. 10 shows such a hanging shaft. The example of sectional drawing of the state which wound up loosely is shown.

  In the example of the rear view of the hanging shaft 24 of the present invention shown in FIG. 5, the surface emitting display body has a four-corner fastening thread 25 on the back surface of the hanging shaft 24 so that the wiring cord 33 and the connector 34 of the surface emitting display body cannot be seen from the front surface. The display is viewed from a surface light emitting display portion hole 30 or a sub display portion hole 31 provided in the middle turning portion 29.

Therefore, even when a square illumination panel is used instead of a circular shape for the surface light emitting display unit, the surface light emitting display can be realized by designing the hole shape within the light emitting area of the surface light emitting display unit. The light emission shape of the part can be set to an arbitrary shape such as a circle or an octagon.
In addition, when the sub display hole is provided, a desired design such as a circle, a heart shape, an hourglass shape, etc. can be used in addition to a square shape.

  In addition, when the surface emitting display part is a mirror surface, a cloth such as Japanese paper or silk or a light diffusing film is provided on the front or back of the hole 30 for the surface emitting display part in order to improve the design or to make the light diffusing surface. You may make it observe, and the transmitted light which passed through them may be observed. In addition, letters, pictures, or lattices may be drawn or printed on Japanese paper, silk cloth, or light diffusion film.

  In addition, the adhesion of the surface emitting display part hole 30 and the sub display part hole 31 around the back surface hole is high and the attachment / detachment is repeated so that no gap is formed between the hole and the surface of the surface emitting display body. A pressure-sensitive adhesive layer, an adhesive silicone resin layer, or an acrylic gel resin layer may be formed.

  Further, the position at which the retaining thread 25 is arranged is determined by the outer shape of the surface light emitting display 8 (see FIG. 6). The means for fastening the surface light emitting display 8 is not limited to the present invention, and may be a means such as a pocket provided on the back surface of the hanging shaft 24 or a magic tape (registered trademark) in addition to the fastening thread 25, and the intermediate turning portion 29. It is also possible to attach the surface light emitting display body 8 to the front side like a colored paper.

  Inside the horizontal bar 32, a biological signal input, receiving device 4, arithmetic processing device 5, data storage / reproducing device 6, external communication device 11, sound output device 12, aroma generator 13, power source, etc. can be built. . At that time, the connector 34 attached to the wiring cord 33 coming out from the horizontal bar 32 is connected to the connector connecting portion 35 of the surface light emitting display body 8, and is connected to the drive circuit 7 built in the casing or substrate of the surface light emitting display body 8. A driving signal is sent to drive the surface emitting display unit 9 and the sub display unit 10 (see FIGS. 1, 3, 5 and 6).

  Further, the position of the center of gravity of the horizontal bar 32 is designed to be on the intermediate line in the width direction of the horizontal bar 32 so as not to tilt when the hanging shaft 24 is suspended.

  When the biological signal input, the receiving device 4, the arithmetic processing device 5, the data storage / reproducing device 6, the external communication device 11, the battery, and the like are built in the casing of the surface emitting display 8, The surface emitting display 8 can be hung like a colored paper on the front side of the hanging shaft 24 without making a hole in 29. However, since the casing of the surface light emitting display 8 is thick and heavy, it is difficult to obtain flexibility as in the case where these devices are separated into horizontal bars 32 and an organic EL sheet is used for the surface light emitting display 8. Become.

  Further, the center of gravity of the surface light emitting display 8 is designed so as to be on the middle line of the width in the left-right direction so as not to tilt when the hanging shaft 24 is suspended.

As shown in FIGS. 7 and 8, the hanging shaft 24 of the present invention is used by being hung on a base 26 and a shaft nail 36 attached to a wall surface by a wall 28 attached to a front tree 27.
Further, it can be attached to or suspended from the ceiling using a front tree and a shaft bar so that the surface emitting display unit 9 faces downward according to the supine state of the subject.

  As shown in FIG. 1, the current or voltage analog signal obtained from the biological signal sensor 2 or 2 ′ according to the depth of respiration is amplified by an amplifier or converted from analog to digital as necessary. A biological signal is input by wire or wirelessly, sent to the receiving device 4, a signal that generates a desired light emission pattern is generated by the arithmetic processing device 5, and a surface emitting display is performed by the drive circuit 7 that controls the output voltage using the signal. The body 8 is driven.

FIG. 11 shows an example in which a sensor using the microwave Doppler effect is attached as a biological signal sensor 2, 2 ′ on a rootstock.
The sensor using the microwave Doppler effect can measure the breathing state of the subject in a non-contact manner without making the subject aware of the sensor. The brightness of the surface emitting display 9 is changed according to the depth of breathing. It is possible to feed back the state of breathing.
Moreover, an acoustic output device and an aroma generator may be provided on the rootstock.

  Further, in the normal organic EL sheet for illumination, there is a problem that the luminance of the central portion is lower than that of the peripheral portion due to the resistance loss of the electrodes and looks unnatural. As shown in the order of (C), when the driving voltage of the surface emitting display 9 is increased, the luminance of the surface emitting display 9 increases from the center, and conversely, the driving voltage of the surface emitting display 9 is decreased. In this case, the brightness decreases in the order of (C), (B), and (A) from the peripheral part, so that it is possible to express with high vitality corresponding to respiration. It is desirable because it is easy to concentrate on.

  In this case, taking a circular surface emitting display as an example, as a method of increasing the luminance from the center and decreasing the luminance from the periphery, the transparent anode 15 shown in FIG. It can be realized by dividing it into a central circle with an anode lead line and at least one C-shaped circular arc surrounding the circle and making the driving voltage at the central part higher than the peripheral arc, Light emission does not continue at the anode lead-out part provided at the arc break, and it becomes unnatural, and a smooth gradation of brightness is not obtained between the center circle and arc, and between the arcs. become.

In FIG. 2, the example of the cross-sectional schematic diagram of the organic electroluminescent sheet 37 used for the surface emitting display body of this invention is shown.
In this example, the transparent anode 15 is not divided into a central portion and a peripheral portion. The thickness is gradually increased to several times.

By this method, the electric field applied to the electron transporting light emitting layer 18 in the central portion is higher than that in the peripheral portion, and the electric resistance of the hole injection transport layer 17 that is the organic EL medium layer in the central portion is lower than that in the peripheral portion. Current density increases.
As a result, the luminance-voltage characteristic of the organic EL element has a non-linear characteristic as shown in FIG. 4. Therefore, when the voltage is increased, the luminance increases from the central portion, and the emission luminance increase with respect to the drive voltage increase. The value at the center of the light emitting display region can be made 50% or more larger than the value at the periphery of the light emitting display region. On the other hand, when the voltage is lowered, it becomes darker from the center, and organic natural light emission can be realized.

  Further, the light emitting portion of the surface light emitting display of the present invention may be a light diffusing surface with a light diffusing film or a light diffusing paint applied, even if it is a mirror surface with a cathode layer. The emission color is based on white, yellow, or yellowish orange emission on the xy chromaticity diagram of the XYZ color system of the International Commission on Illumination, which is close to the moonlight or golden brightness. In addition, gold foil or silver foil is decorated on paper, cloth, or film pasted on the light-emitting surface of the surface-emitting display or the hole for the surface-emitting display, decorated with letters such as titles or letters, full moon and lotus flowers. You can also draw a desired picture, such as fruit or fruit, or print a photo.

  When drawing such pictures, using ink containing nanoparticles such as silver, gold, etc. and red, pink, orange, yellow, green, blue, blue, brown, etc. composed of those composite metals, High coloring power, transparency and light resistance can be obtained, and light from a surface light emitter can be transmitted as compared with the case of using a normal pigment ink, so that a beautiful color can be obtained and high durability can be obtained. For this reason, when the organic EL sheet is driven, there is an effect that characters and pictures appear more prominent due to differences in brightness and color.

  In addition, by placing translucent Japanese paper or silk cloth on the hole provided in the turning part of the hanging shaft and arranging the surface light emitting display body of the present invention behind, the surface of the surface light emitting display body is placed on the surface of the Japanese paper or silk cloth. It is also possible to make another picture drawn or printed stand out like a shadow picture.

  In addition, by increasing the film thickness of the organic EL medium layer such as the hole transport layer in the region that becomes the character or design of the organic EL sheet in order to increase the brightness of the character or design, the region that becomes the character or design The value of the current flowing in the light emitting layer can be made higher than that of the ground portion in the peripheral portion, and the luminance can be increased.

  In addition, by changing the refractive index of the organic EL medium layer material and the concentration of light-scattering additives from the surrounding peripheral part and changing the light emission color and brightness by the light interference effect and scattering effect, it is possible to bring out characters and designs. is there.

  As described above, the mental health / breathing training system of the present invention makes it possible to monitor biological signals such as respiration, pulse, brain waves, etc. even without contact so as not to give a burden to the subject. By visualizing the change in real time, it becomes possible to meditate and lightly close the eyelids or to effectively feed back the subject's own state even in a half-eye state.

  In addition, the surface emitting display used in the mental health / breathing training system of the present invention is brightened radially from the center to the periphery when the emission intensity becomes bright according to a biological signal, and when it becomes dark A kind of unique light emission that darkens from the center to the center is possible, thereby enabling effective training. A thin and flexible organic EL sheet can be preferably used. Furthermore, the hanging-type mental health / breathing training system can be used more effectively by training for zazen and meditation, and the effect can be further enhanced by drawing a pattern on the surface of the surface emitting display unit.
