Description

Physiological feedback system

The present invention relates to a physiological feedback system, and more particularly to a system that combines physiological information instant feedback and respiratory regulation.

In recent years, more and more research has focused on how the human body influences the body's operating system through self-consciousness regulation to achieve physical and mental health effects, such as biofeedback (including neurofeedback). , meditation, breath training, etc. are currently supported by a large number of research results, and there are more and more people using methods.

Among them, physiological feedback is a learning program in which the human body learns how to change physiological activities for the purpose of improving health and efficacy, in which physiological activities such as thinking, emotion, and behavior can be changed in the human body, for example, , brain waves, heart rate, respiration, muscle activity or skin temperature, etc., will be monitored by the instrument, and the instrument will quickly and accurately return information to the subject, since this information is related to the physiological changes desired, therefore, After obtaining the information, the tester can adjust the self-consciousness and strengthen the physiological response required.

In addition, the common ways of sitting meditation are: concentration, mindfulness, and compassion and love, all of which involve self-consciousness control. The purpose of meditation is consistent with many of the goals of clinical psychology, psychiatry, preventive medicine, and education. More and more research shows that meditation may help relieve depression and chronic pain. And it is conducive to improving the overall happiness.

In addition, there is increasing scientific evidence that self-consciousness regulation during meditation can change the functional circuits of the brain and produce benefits for the mind, brain, and the entire body. Many neuroscientists have also begun. Understand the effects of meditation on the human body by observing the brain reaction during meditation. This is somewhat similar to the so-called neurofeedback, except that when performing neurophysiological feedback, as with physiological feedback, information about brain activity is immediately available to the user.

It can be seen from the above that when it comes to improving the physical and mental health through the body's own regulation mechanism, the most important thing is that the user must concentrate on helping the self-consciousness to be regulated. Therefore, when attention is more easily concentrated, The effects of self-awareness control are naturally easier to achieve.

Generally, in the process of meditation that requires concentration, it is usually emphasized that the meditator must focus on the rhythm of breathing, especially in the case of mental wandering, it is necessary to refocus attention on the breath rhythm of a breath, therefore, focus Respiratory rhythm is a method known to increase attention.

Breathing In the absence of conscious intervention, breathing is controlled by the autonomic nervous system, which automatically adjusts the breathing rate and depth according to the needs of the body. On the other hand, breathing can be controlled by consciousness, within a limited range. The human body can control the breathing rate and depth by itself. Therefore, studies have shown that the balance between the sympathetic nerve and the parasympathetic nerve can be affected by controlling the breathing. In general, the parasympathetic nerve activity is increased during exhalation, and the heartbeat is slowed down. The opposite is during inhalation.

Therefore, when you need to concentrate and focus on the rhythm of the breath, Attention to the rhythm of exhalation and exhalation to achieve the concentration and stability of the effect, but also at the same time will have an impact on their own autonomic nervous system, at this time, as long as the impact of breathing on the autonomic nervous system and physiological feedback, neurophysiological When the goals of feedback or meditation are the same, for example, to relax the mind and body, it is natural to increase the effect of the physiological feedback by increasing the control of the breathing to achieve a complementary effect.

Also because breathing is between the conscious and unconscious controls, breathing training is also seen as a procedure that can improve physical and mental effects by affecting the body's functioning. In general, breathing training is a process of adjusting one's breathing through consciousness. For example, a common breathing training method is the Buteyko breathing technique, which advocates breathing through the nose and is controlled by consciousness. A breathing method that reduces the breathing rate or the amount of breathing may have a therapeutic effect on diseases caused by increased breathing rate or excessive ventilation, such as asthma, or other respiratory related diseases, for example, sleep breathing.

In addition, the breathing training can also be performed with an external guiding signal. Generally, the guiding signal is used to guide the user's breathing, for example, guiding the breathing rate, and/or the ratio of exhalation to exhalation time, etc. Depending on the purpose, the content of the pilot signal may also change. For example, during the Buteco breathing training, the pilot signal provides a slower breathing rate to meet its training objectives.

Generally, during the breathing training process, the user is mostly focused on the adjustment of the breathing, but since the purpose of the breathing training is also to improve the physical and mental health, if the user can provide real-time information about the physiological state during the breathing training, In order to let the user know whether the progress of the breathing adjustment is progressing toward the intended goal, it is believed that it will help to further improve the efficiency of the breathing training and achieve a multiplier effect.

Therefore, there is a real need to develop a novel system that provides further evidence of respiratory adjustments when the user performs physiological feedback, meditation, or neurophysiological feedback through self-consciousness control, so that the effects of breathing on improving physical and mental health Can be displayed at the same time, and then complement each other to make the achievable effect even higher.

In addition, when based on breathing training, the user can also change the breathing behavior or other physiology through the regulation of self-consciousness while performing breathing training through the way of letting the user know his or her physiological state in real time. State, further enhance the effect of training.

It is an object of the present invention to provide a physiological feedback system that provides instant autonomic nervous activity information and respiratory guidance signals through a single sensible signal generating source, so that the user can follow the breathing during the physiological feedback process. Guide the signal to achieve further improvement in physiological feedback.

Examples may be implemented when measuring; Figure 6 shows a possible implementation example when measuring brain electrical signals and heart rate sequences in accordance with the system of the present invention. And Figure 7 shows a possible implementation example when measuring skin electrical activity in accordance with the system of the present invention.

The purpose of the system of the present invention is to integrate a program that affects a physiological state through self-awareness adjustment and a respiratory regulation in the same training section, and achieve an addition by forming a feedback loop by interacting with the user. It affects the physiological state, so it can be widely used in physiological feedback, neurophysiological feedback, meditation, and/or respiratory training, and various programs that influence the physiological state through self-consciousness regulation, so that the results achieved by the program can be further improved. .

Under this principle, the system according to the present invention has a wearable physiological sensing device and a perceptible signal generating device, wherein the wearable physiological sensing device is used to obtain physiological activity in the training segment. The physiological signal affected by the change and the source of the sensible signal are used in the training section to be used by the user to perceive the signal, for example, the visually perceptible signal and/or the auditory sensible signal. Provides breathing guidance and information about physiological activities, such as immediate physiological status, changes in breathing behavior, and/or effectiveness of training execution.

Referring to FIG. 1, there is shown a preferred embodiment of a system in accordance with the present invention. This embodiment is directed to providing an implementation of a neurophysiological feedback system incorporating breathing training. Accordingly, the wearable physiological sensing device is It is implemented as a head-mounted EEG detecting device 10, and the sensible signal generating source is implemented as an illuminant 12.

When the user performs a neurophysiological feedback program using the neurophysiological feedback system of the present invention, as shown, the head-mounted EEG detecting device is placed on the head to The brain wave of the user is obtained through the electroencephalogram electrode provided inside the headband. Here, the position of the electroencephalogram electrode is not limited, as long as it is a corresponding sampling point at which a specific brain cortex position of the brain wave can be obtained, for example, Common sampling points include Fp1, Fp2, O1, O2, etc., or any position defined by the 10-20 system, and the location and number of EEG electrodes can be determined according to the purpose of the neurophysiological feedback performed. For example, the measurement of the multi-channel EEG signal may be performed by increasing the number of electrodes, or the electrode may be provided on the ear as a reference point or the like, and thus, there is no limitation.

Thereafter, the illuminant 12 is placed at a position where the front of the body can be seen naturally, and the EEG detecting device on the head communicates with the illuminant, for example, through a general wireless communication method such as Bluetooth or WiFi. The respiratory physiological feedback procedure can be started.

Here, due to the combination of breathing training and neurophysiological feedback, based on the progress of the breathing training, the user needs to provide the breathing guidance signal, and based on the neurophysiological feedback, the user needs to be changed due to the execution of the neurophysiological feedback. Information about physiological activities and/or other relevant information, and the illuminant is the medium provided.

In this embodiment, the signal generated by the illuminator to be perceived by the user includes the illuminance and the illuminating color to respectively represent different information, wherein the illuminating intensity is used to represent the breathing guide, and the illuminating color is used to Demonstrate changes in the user's physiological activities.

Since the purpose of the breathing guide signal is to allow the user to follow the breathing, it is necessary to be able to express the difference between the inhalation and the exhalation. Therefore, the illumination system continuously changes the intensity of the illumination to represent the continuous change of inspiration and exhalation. For example, the gradual increase in luminous intensity is used as a guide for gradual inhalation, and the illuminating intensity is gradually weakened as a guide for gradual exhalation, so that the user can clearly and easily follow the suction.

One of the choices when performing a neurophysiological feedback program that targets relaxation It is to observe the proportion of alpha waves in brain waves. In the brain wave, in general, the α wave predominates to indicate that the human body is in a state of relaxation and waking state, so the degree of relaxation can be known by observing the proportion of the alpha wave. Accordingly, after the neurophysiological feedback procedure is started, the illuminator provides respiratory guidance (through continuous change in illuminance intensity) to guide the user to adjust their breathing, and at the same time, the EEG detecting device worn on the head also performs brain The detection of the wave, and the obtained brain wave, after a calculation of the calculation, can obtain an analysis result, for example, the proportion of the alpha wave, and generate a related information about the user's brain activity based on the analysis result. Then, the illuminant changes its illuminating color according to the information of the related user's brain activity.

For example, a reference value may be obtained at the beginning of the program, for example, the alpha wave is a percentage of the total brain wave energy, and then the analyzed result is compared with the reference value to obtain a reference value. The relationship between, for example, the increase or decrease of the ratio, and the illuminant can instantly convey the change of the physiological state to the user through the change of the illuminating color based on the illuminant, for example, the color representation can be utilized, for example, the closer The more relaxed the blue color, the more nervous it is, the more intense it is. It can also be based on the depth of the same color. The lighter the color, the more relaxed it is. The darker the color, the more nervous it is. In this way, the user can easily pass the color. Change to know that your physical and mental state is nervous or relaxed, and also follow the breathing guide while also self-regulation, so that the illuminating color further tends to a more relaxed goal.

Alternatively, the degree of relaxation or emotional state of the human body can be understood by observing the energy balance and synchrony of brain activity between the two hemispheres; or, the brain can be detected by detecting the amount of blood flow in the cerebral cortex. The degree of activity of the ministry to judge the degree of relaxation of the body and mind.

In addition, when aiming at increasing concentration, you can choose to observe the ratio of the θ wave to the β wave. In the brain wave, when the β wave dominates, the human body is in a state of waking and nervous, and the θ wave accounts for The advantage indicates that the human body is in a state of relaxation and interruption of consciousness. Therefore, the purpose of improving concentration can be achieved by increasing the ratio of the beta wave to theta wave, for example, treating ADHD (Attention deficit hyperactivity disorder). One of the methods of patients is to observe the ratio of the θ wave/β wave through neurophysiological feedback. Accordingly, after the neurophysiological feedback procedure is initiated using the system of the present invention, the illuminator provides a respiratory guidance signal (through continuous changes in illumination intensity) to guide the user to adjust their breathing while simultaneously wearing the head. The electrical detection device also performs brain wave detection to further analyze the ratio of the θ wave and the β wave, for example, the ratio of the θ wave and the β wave to the total brain wave energy, respectively, or calculate θ/θ+β and β/θ. +β, etc., and then, according to the analysis result, information about the brain activity of the user is generated, and the illuminant is based on the information of the brain activity of the related user, and the user changes the color of the illuminating color to the user immediately. It conveys changes in the function of the brain. For example, it can be represented by multiple colors. The closer to the blue, the lower the concentration. The closer to the red, the higher the concentration. The lighter the depth of the same color. The lighter the color, the more focused. The lower the force, the darker the color, the higher the concentration. As a result, the user can easily know whether his concentration is improved through the change of color, and follow the call. But also self-guided regulation of consciousness (self-regulation), the emission color tends to further improve the focus target.

In addition to observing the ratio of theta wave to the beta wave, the slow cortical potential (SCP) is also a brain activity that is often observed in the neurophysiological feedback of concentration. Among them, the negative shift of the SCP (negative shift) Regarding the more concentrated attention, and the positive shift of the SCP is related to reduced attention.

Therefore, when the illuminating color represents a physiological state, it can be implemented as various possibilities, for example, the degree of relaxation or concentration after conversion can be used as a basis for change as described above, or It is used to indicate changes in physiological signals, for example, changes in the proportion of alpha waves, and so on. Therefore, there is no limitation. Moreover, there is no limitation on the way the illuminating color changes. The key point is that the user can understand his or her physiological state simply and clearly, and can drive the user to self-consciously control to achieve the target physiological state.

In addition, the illuminating color may alternatively be used to indicate other information about the usage status, for example, to indicate the accumulated training hours, for example, the darker the color, the longer the accumulated training time is for use. Understand the cumulative effect brought by the physiological feedback program with cumulative effect, and here, the accumulation time may be a cumulative period of time, for example, within one week, or accumulated in the time of the training, etc., depending on the user The change in color is also required; alternatively, the illuminating color can also be used to indicate the start of time for each training session, for example, from the beginning of the light color to deeper to indicate a gradual approach to the training tail. Therefore, it is a feasible way, there is no limit.

Furthermore, the illuminant can also be implemented as a time for setting the training section, for example, 10 minutes, 15 minutes, and automatically shutting down at the end of the time, so that the user can concentrate on breathing regulation and self. Consciousness control is more conducive to the achievement of the target effect.

Therefore, with the system of the present invention, the user can naturally combine the breathing regulation and the program that affects the physiological state through self-consciousness control, without special learning steps, and the important reason is that the sensible signal generating source The generated perceptible signal includes two kinds of information. For example, in the embodiment of FIG. 1, the visually perceptible signal generated by the single illuminant expresses the respiratory guiding signal and the immediate physiological state through the illuminating intensity and the illuminating color, respectively. News.

In the prior art, when performing neurophysiological feedback, the feedback mode for the user is usually implemented as, for example, a moving object with the effect of performing physiological feedback. Body, for example, a balloon floating in the air, the more the body relaxes, the higher the balloon floats; or the pattern that changes with the physiological state, for example, the flower that continues to bloom because the body is more and more relaxed; or The change in the measured value is directly displayed; and the way in which the breathing guide is provided is mostly implemented, for example, the waveform through the up and down undulation represents inhalation and exhalation. Therefore, when combining the two, the user is easily disturbed by the visual display mode of the value that is too complicated, too large, or not easy to understand, and may even increase the user's mental stress, and the effect does not rise and fall.

In addition, there is also a conventional technique, as shown in US6212135, which guides the user to perform exhalation, expiration pause, inhalation, and inhalation pause during breathing training through the form of the illuminator, but the manner described can only The breathing behavior pattern that the user follows can not let the user know the impact of the breathing training performed on the body at the same time, so it is only suitable for simple breathing training.

Therefore, in view of the above-mentioned possible problems, the present invention considers how to provide two kinds of information through a single object when considering how to provide information to the user, so as to simplify the complexity as much as possible, and not to cause a mental burden on the user. It also makes it easy for users to use the system. The advantages of the display mode disclosed by the present invention include:

1. The change in the intensity of the luminous intensity is similar to the general rhythm and rhythm representation. The user does not need to go through the thinking conversion, and can intuitively obtain guidance to control inhalation and exhalation.

2. The illuminating color is an easy-to-understand physiological state representation for the user. Compared with directly providing numerical changes, the human body can easily identify the change in degree and level by using the color type and/or the depth change. Sense, so it can respond more naturally and make self-consciousness.

3. There is only one focus of vision. There is no need to combine two programs and need to pay attention to two focuses. The problem is more helpful to concentrate.

Therefore, combining the complexity of the two programs, through the well-designed and perceptible signal representation, can be eliminated, which not only effectively reduces the user's sense of burden during use, but also achieves a new effect enhancement. Feedback program.

In the implementation, the illuminator may have various implementation options. For example, in terms of external appearance, the illuminator may be a sphere as shown in FIG. 1 , or may have other shapes such as a square shape and a pyramid shape, and further may be implemented as The floating form by magnetic force increases the use of fun; in addition, it can be implemented to emit only the entire illuminant, and can be implemented as only partial illuminating. As shown in FIG. 2A, the illuminant transmits through a top portion. The light-transmitting portion exhibits its illuminating behavior, and the permeable portion can also be implemented in different shapes to attract user's interest, for example, a multi-level concentric ring (Fig. 2B), or a radial shape. (Fig. 2C) and the like, without limitation.

In addition to using a single illuminant to provide illumination intensity and illuminating color change, it can also be achieved by other devices having a display function. For example, it can be a light source on a screen, for example, a tablet computer or a mobile phone. a watch, a screen of a personal computer, etc. Further, the light source can also be implemented as a part of an image, for example, a head of a human figure, or an abdomen position, etc., to help the user imagine the body during self-consciousness regulation. In addition, in addition to the form of the physical light source, the aperture is also a good implementation. For example, the aperture around the human head also helps the user to imagine. On the other hand, when the light source or the aperture on the screen as described above is implemented, the change in the diameter of the light-emitting range can be further indicated by the change in the diameter of the light-emitting range, as shown in FIG. 2D, to enhance the effect of guiding the inhalation and the exhalation. Therefore, it can be changed according to the actual implementation situation, and there is no limitation.

In addition, the system according to the present invention may additionally provide an auditory sensible signal, for example. For example, sound or voice, in order to provide a feedback program when the user needs to close the eye, for example, the intensity of the volume can be used to represent the continuous change of inspiration and exhalation, and through different types of sound, for example, Birds, waves, etc., or different tracks represent different physiological states; or, voices can be used to indicate the user to inhale and exhale, and the sound frequency represents the physiological state, for example, the higher frequency sound representation The more nervous, the lower the frequency means the more relaxed, etc. Therefore, there is no limit. Moreover, the auditory sensible signal can be implemented as being provided by the audible signal generating source and/or by the wearable physiological sensing device, again without limitation.

Still further, the respiratory guidance signal can also be implemented to make an immediate adjustment based on a change in the physiological state of the user. In general breathing training, the types of respiratory guidance signals are mainly divided into three types, one is a preset fixed breathing change mode, for example, the breathing rate is set to be fixed 8 times per minute; the other is preset preset breathing changes over time. Mode, for example, in a 15-minute training session, the breathing rate is set to 10 times per minute for the first 5 minutes, 8 times per minute for the 5 minutes in the middle, and 6 times per minute for the last 5 minutes; and one more A pattern of changes in breathing that changes dynamically with physiological conditions. Therefore, in the present invention, the respiratory guidance signal can obtain a physiological signal obtained by the wearable physiological sensing device in addition to a respiratory change mode that is preset to be fixed and changed with time, for example, the embodiment of FIG. The electroencephalogram signal obtained by the midbrain detecting device can be implemented to dynamically change with the physiological state to provide a breathing change mode that more effectively guides the user toward the target physiological state.

There are many options for the manner in which the user's physiological state affects the breathing guide signal. For example, when the degree of relaxation of the user has increased and remains stable, the respiratory guidance signal can be implemented to further reduce the breathing rate, for example, from 8-10 times per minute to 6-8 times per minute, to further Increase the degree of relaxation; or, it can be implemented as the degree of relaxation of the user has reached When the target is expected, or when the control of the breath has steadily matched the breathing guide, the supply of the breathing guide signal is stopped, and the user can focus on the self-consciousness regulation, only when the breathing is found to be unstable or relaxed. When it is lowered again, the breathing guide is started again, so there is no limit.

Furthermore, in particular, it may be implemented as a procedure for allowing the user to alternately perform respiratory regulation and change the physiological state through self-consciousness regulation through the presence or absence of the provision of the respiratory guidance signal. As mentioned above, according to research, when the procedure of affecting physiological state by self-consciousness regulation is carried out, especially in neurophysiological feedback and meditation, if the breathing energy is in a smooth and stable state, the effect of feedback can be Gaining and multiplying, therefore, by providing the breathing guide signal intermittently for a period of time, the user is accustomed to the breathing mode to achieve stable breathing, and then, by stopping the breathing guide, the user is accustomed to the natural continuation. In the breathing mode, simply focusing on the self-awareness control process, this process will help to further improve the feedback effect.

Moreover, since the breathing training has a delayed response to the influence of the autonomic nerve, the method of intermittently providing the guiding signal, coupled with the characteristics of the present invention combined with the breathing training and self-awareness control program, can provide no breathing guidance. The period during which the effect of breathing training on the autonomic nerve is presented is convenient for the user to perform self-awareness control procedures, and the training effect is added.

Here, the alternating conversion of the breathing training and the self-awareness control program, that is, the presence or absence of the respiratory guidance signal, may be determined according to the physiological state of the user as described above, or may be fixed according to a preset time interval. There is no limit to switching. In addition, when the fixed switching mode is adopted, it may be further implemented that the breathing guide signal is switched between fast and slow breathing rate, for example, 6-8 times per minute and 10-12 times per minute, and such Way It can help, for example, focus on switching training to achieve more flexible control.

Here, it should be noted that the wearing structure for acquiring the EEG signal can be implemented in other forms besides the wearing form as shown in FIG. 1, and FIG. 3 shows the setting through the ear wearing structure. In the example of the electroencephalogram electrode, in this example, the electroencephalogram electrode can obtain the EEG signal by the ear-wearing structure and the skin in the vicinity of the ear or the ear, and therefore, it is also a convenient method and is not limited.

Then, according to the concept of another aspect of the present invention, it is also possible to provide a basis for providing information about the physiological state of the user by detecting the breathing behavior of the user. As shown in FIG. 4A, the user performs a breathing training program through the respiratory motion sensing element 20 disposed on the abdomen and a screen having a light source 22 placed in front of the body, wherein the function of the respiratory motion sensing element is to feel The body cavity undulation caused by breathing action, and thus the information provided includes, but is not limited to, the duration of exhalation, exhalation pause, inhalation and inhalation pause, and the rate of respiration, which is used by the user. Abdominal or thoracic breathing (ie, gas inhalation mainly causes abdominal or chest swelling), and ventilation (so-called breathing depth), etc., where respiratory motion sensing elements can be used, but not Limited to RIP straps (Respiratory Inductance Plethysmography (RIP), and piezo respiratory effort belts.

Therefore, when performing a breathing training program through the system as shown in FIG. 4A, one form that can be implemented is to provide a difference between the actual breathing behavior pattern of the user and the breathing guidance signal as a user's self-consciousness regulation. For example, the difference between the two can be obtained by calculating the score. For example, the pre-loaded calculation formula is used to calculate the difference between the actual breathing behavior pattern of the user and the pilot signal, for example, for breathing. Rate, call Analysis of the gas period/inhalation period ratio, etc., the higher the score, the smaller the difference, the lower the difference indicates the difference, and the color change indicates the level of the score, for example, the same color shade or continuous change of different colors Indicates the level of the score so that the user can know immediately and make an immediate adjustment.

Another form that can be implemented is to provide information about the patient's respiratory stability. Since stable breathing helps to maintain physical and mental relaxation, it can also indicate that the body and mind are in a relaxed and stable state to a certain extent. Therefore, by knowing the information about the respiratory stability of the child, it is also helpful for the user to adjust the self-consciousness. For example, the manner of expressing the stability may be expressed by means of a score as described above. For example, the rate of change of the breathing rate may be calculated by a preset calculation formula, for example, every 1 minute, and the lower the rate of change, the stability is expressed. The higher the score, the higher the score, and the change of the luminescent color, or the score obtained by observing the stability of the respiratory amplitude, or the result of the comprehensive evaluation of the respiratory rate and the respiratory amplitude as a feedback basis; It is also possible to directly indicate the change in the breathing rate or the respiratory amplitude by the illuminating color, and therefore, there is no limitation.

Yet another form that can be implemented is to provide information about changes in ventilation. Usually, when breathing training, in addition to the breathing rate, the amount of ventilation is also the focus of attention, because part of the purpose of breathing training is to solve the problem of hyperventilation, and when breathing in daily life, If you can maintain a smooth and not too much ventilation, it will also help to maintain a relaxed and stable state of mind and body. Therefore, it can be used as a basis for self-adjustment by providing information on the amount of ventilation during breathing. For example, a standard value can be preset, and the result compared with the standard value is presented to the user by the illuminating color. For example, the illuminating color can be maintained at all times, and only the measured ventilation is higher. The standard value only changes color, or it can be that the darker the illuminating color, the more the standard value is exceeded, and the lighter the more Near standard value; in addition, the amount of ventilation can be directly transmitted through the light color depth or continuous color change without presetting the standard value.

Yet another form that can be implemented is to provide information about whether the user is performing abdominal breathing or chest breathing. Studies have shown that the use of abdominal breathing can increase the activity of parasympathetic nerves, and can further enhance the effect of relaxing the body and mind to relax the body and mind, so when the respiratory motion sensing element is placed on the chest and / or abdomen, It can be used to distinguish the expansion of the abdomen and the chest during breathing as a reference for the user to adjust the breathing behavior. For example, the respiratory motion sensing element can be set separately from the abdomen to understand the undulation of the abdomen, or to set the breathing separately from the chest. The motion sensing element is configured to know whether the chest is undulating (on the premise that abdominal breathing is desired), or as shown in FIG. 4B, the respiratory motion sensing element 20 is provided on both the chest and the abdomen; in addition, some abdominal type Breathing training requires breathing for a specific part, for example, the upper abdomen or the lower abdomen. This can be achieved by adjusting the position of the breathing action sensing element on the abdomen to achieve detection of different parts. In the case of providing user-related information, for example, the illuminating color may be used to indicate the amount of ventilation detected by the respiratory motion sensing element disposed on the abdomen, or may be indicative of the respiratory motion set in the chest. Whether the measuring element detects the expansion of the chest, or the ratio of the degree of expansion of the abdomen to the chest, etc., is therefore not limited.

In addition, another piece of information that can be provided is that the user is breathing through the nose and/or mouth. In general, the preferred way to breathe is to breathe through the nose. When the mouth is involved in breathing or breathing through the mouth only, the amount of ventilation will be greater than breathing through the nose alone, which will easily cause excessive breathing. When the nose inhales air, the air can be heated and humidified, while the bristles inside the nose and nose can filter out particles, preventing it. It enters the lungs. According to the report, many people only breathe unconsciously through the mouth. Therefore, if you change your mind consciously, you can return to breathing with your nose. Therefore, you can provide such information during breathing training. Helps the user to breathe in a more correct way and enhance the training effect. In the case of providing user-related information, for example, the user can know the presence or absence of oral airflow during the breathing training, and/or nasal airflow and oral airflow through the change of color. The proportion, etc., can be changed according to actual needs. Here, in order to distinguish the respiratory air flow between the mouth and the nose, it is necessary to use a sensing element that can detect changes in the outlet and nasal air flow, for example, a respiratory airflow tube or a nasal passage tube, which can detect changes in the airflow of the mouth and nose. And a thermal sensor placed between the nose and mouth to sense the temperature change of the respiratory airflow.

Furthermore, since the breathing affects the autonomic nervous system, the heartbeat that is also controlled by the autonomic nerve changes, the so-called Respiratory Sinus Arrhythmia (RSA), that is, the heartbeat is accelerated during inhalation. And the phenomenon of slowing the heartbeat during breathing. Therefore, another way to obtain the breathing behavior of the user is to measure the heart rate. In general, when the breathing and the heartbeat are in synchronism with each other, the respiratory changes can be known by analyzing the heart rate sequence.

Common ways to obtain a heart rate sequence include, but are not limited to, obtaining a heart rate sequence by detecting an arterial pulse, for example, a light sensor disposed at an ear, a finger, a wrist, a forehead, etc., directly placed on the artery. An arterial pulse can be obtained by a pressure sensor, a cuff, or the like. Here, the photosensor means a light-emitting element and a light-receiving element, and the light is obtained by the principle of PPG (photoplethysmography). The sensor of the signal, for example, is measured by means of penetration or reflection. In addition, the heart rate sequence can also be obtained by measuring the electrocardiogram, for example, by placing it on the hands, the ears and other parts of the body. The electrocardiogram is obtained by the finger and other positions of the body, and at least two electrocardiographic electrodes on the trunk. For example, FIG. 5A shows an embodiment of obtaining an electrocardiogram through two finger-type ECG electrodes, and FIG. 5B shows an example. An embodiment in which an ear and a wrist are contacted to obtain an electrocardiographic signal, and a fifth embodiment shows an embodiment in which an electrocardiographic signal is obtained by touching an exposed electrocardiographic electrode of an ear wearing device attached to the ear, thereby There are various options, and can also be changed according to actual needs, no restrictions.

Therefore, according to another aspect of the present invention, the information provided to the user through the color of the illuminating light may also include information on a plurality of related autonomic nerves derived from the heart rate and the RSA information. For example, according to research, Better harmony and synchronization between breathing and heart rate represents a more orderly and coordinated heartbeat rhythm, that is, the human body is in a relatively relaxed and stable state. Therefore, it can be used to analyze whether the breathing and heart rate are harmonious and synchronized. To determine the effectiveness of respiratory guidance training and/or as information that is immediately available to the user, for example, frequency domain analysis can be performed on the heart rate sequence, and the more concentrated the spectrum, the higher the synchronization between the two, or can be calculated The phase difference between the two, when the phase difference is smaller, indicates that the synchronization between the two is higher. Therefore, the analysis result about the harmony or the synchronization can be presented to the user through the change of the depth and the different colors of the same color. For example, the lighter the color, the higher the harmony/synchronization, the more relaxed the body, and conversely, the darker the color, the lower the harmony/synchronization The user can immediately know whether the breathing training/physiological feedback performed by the user advances toward the relaxed target; furthermore, the breathing guiding signal can be adjusted by analyzing the result to further guide the user's breathing, thereby making the body and mind The state gradually tends to a more relaxed goal.

Alternatively, as shown in FIG. 4C, the electrocardiographic electrode 24 is further disposed in the respiratory motion sensing element, and the heart rate sequence is obtained by the electrocardiogram, and the respiratory motion is coordinated. The information on the related respiratory behavior obtained by the sensing element can also obtain the analysis result of the harmony degree and the synchronization as described above, and therefore, there is no limitation.

Furthermore, since the RSA information can be obtained through the heart rate sequence, the synchronization between heart rate, respiration and EEG signals can also be observed as a basis for feedback. According to research, exhalation and inhalation cause fluctuations in intravascular blood volume, and this fluctuation also reaches the brain with blood flow, which causes brain waves to approach the low frequency segment of the respiratory rate, for example, below 0.5 Hz. Fluctuation, therefore, in addition to knowing whether the synchronization between the two is achieved by resonance, the breathing pattern can be known by observing the brain wave, and the autonomic nerve is also caused by the sinus node and the vascular system of the heart. Systematic regulation, and the autonomic nervous system also feeds heart rate and blood pressure changes back to the brain through the baroreceptor system, which in turn affects the function and function of the brain, for example, affecting the cerebral cortex, and can be affected by the brain The graph measured, coupled with the conscious control of breathing, can affect the heart rate caused by the influence of the autonomic nerve. Therefore, there is a relationship between the three, so the good synchronicity between the three can represent the human body. The state of relaxation, according to which the correlation analysis results can also be used as information to provide users with self-awareness adjustment for neurophysiological feedback.

Therefore, as shown in FIG. 6, the photo sensor can be coupled to the head-mounted EEG detecting device of FIG. 1, for example, through the ear wearing structure 14, for example, the ear clip structure. Or set on the inside of the headband to get the heart rate sequence from the forehead, etc., so that through more kinds of physiological signals, the physiological state of the user can be more accurately evaluated, which naturally provides a closer to the actual physiological state. Instant information, allowing users to more easily move toward the target physiological state.

In addition, in addition to the common purpose of relaxing and breathing through breathing training, Other purposes can be achieved by regulating breathing. For example, because RSA amplitude is related to parasympathetic activity, a larger RSA amplitude represents better parasympathetic activity, and when the increase in parasympathetic activity is sufficient, it can be triggered. The relaxation response of the human body relieves the accumulated pressure. Therefore, by observing the user's heart rate change pattern, and when the heart rate starts to accelerate, the respiratory guide is used to inform the user that the inhalation can be started, and the heart rate begins to slow down. At this time, the breathing guide is used to inform the user that the exhalation can be started to achieve the effect of increasing the amplitude of the RSA. Therefore, the breathing guidance signal that helps the user to trigger the relaxation reaction of the human body can be provided in this manner; In addition, for example, whether the illuminating color indicates whether the user's breathing matches the breathing guide signal, or whether the parasympathetic activity is increased or not, the effect of the breathing guide can be further improved. In addition, due to the magnitude of the amplitude of the peaks and troughs of the RSA, that is, the difference between the maximum and minimum values of the heart rate during a breathing cycle is related to the activity of the autonomic nervous system. This information is provided to the user on the fly as a basis for the user to adjust the physiological activity.

Further, after the heart rate sequence is obtained, HRV (Heart Rate Variability) analysis can also be performed, and HRV analysis is one of the common methods for learning the activity of the autonomic nervous system, for example, frequency domain analysis can be performed (for example, Frequency domain) to obtain total power (TP) that can be used to assess overall heart rate variability, high frequency power (HF) that can reflect parasympathetic activity, sympathetic nerve activity, or sympathetic nerves The low frequency power (LF) of the parasympathetic nerve simultaneous regulation results, and the LF/HF (low high frequency power ratio) which can balance the activity of the sympathetic/parasympathetic nerves, and can also be borrowed after frequency analysis. The degree of harmony of the operation of the autonomous nerve is known by observing the state of the frequency distribution; alternatively, time domain analysis (Time Domain) can be performed, and Obtaining an SDN that can be used as an indicator of overall heart rate variability, SDANN, which can be used as an indicator of long-term overall heart rate variability, RMSSD, which can be used as an indicator of short-term overall heart rate variability, and R-, which can be used to estimate high-frequency variation in heart rate variability. MSSD, NN50, and PNN50.

Therefore, the result of the HRV analysis can be immediately provided to the user through the change of the illuminating color as information for letting the user know the activity of the autonomic nerve, where the HRV analysis is performed on the heart rate sequence for a period of time. Analysis, therefore, the implementation of the instant HRV analysis can be implemented by the concept of the Moving Window, that is, first determining a time period, for example, 1 minute, or 2 minutes, after which, by continuously The way in which the time zone moves backwards, for example, every 5 seconds, the HRV analysis result can be obtained continuously, for example, an HRV analysis result is obtained every 5 seconds, thereby achieving the purpose of providing an immediate HRV analysis result, and also Using the concept of weighting, the proportion of the physiological signals closer to the analysis time is moderately increased to make the analysis results closer to the immediate physiological condition.

Furthermore, according to a further aspect of the present invention, the system according to the present invention can also be implemented to provide a user's own breathing behavior pattern to allow the user to know himself through a physiological sensor that can detect the breathing behavior of the user. The actual breathing situation, for example, can provide the actual breathing rate of the user, as well as changes during exhalation/inhalation, etc., through successive changes in the intensity of the illumination. At this time, the instantaneous physiological state information provided by the illuminating color may have different possibilities depending on the physiological sensor used. For example, the information about the related breathing behavior may be the same, for example, the breathing rate may be Changes, respiratory stability, ratio of exhalation to inhalation, volume of ventilation, compliance with abdominal breathing behavior, changes in oral/nose airflow, etc.; in addition, other physiological information, For example, when the analysis is performed by taking the heart rate sequence, the breathing behavior pattern of the user can be obtained on the one hand, and on the other hand Other physiological status information such as the above-mentioned autonomic nervous activity and RSA related information; or, through another physiological sensing element, physiological state information may be obtained, for example, when the brain electrical signal is acquired and the brain activity is known. Etc. Therefore, there is no limit.

In addition to the various possibilities described above, it may be implemented to provide a comparison between the difference between the actual breathing mode and the breathing guidance signal of the user and a predetermined rating table. For example, the preset rating table may be provided as The difference between the respiratory rates is compared to the benchmark. For example, the difference is divided into blue: 0-20%, green: 20-40%, yellow: 40-60%, red: 60-80%, so the user The difference between the breathing and the breathing guide signal can be known through the color presented, and the breathing can be adjusted.

Further, in this case, a breathing guidance signal, such as sound or voice, may be further provided through an auditory senseable signal to adjust the physiological state information presented by the color of the light, and also as a user. The basis of the breathing pattern of the self, and/or let the user know if their breathing (as revealed by the intensity of the light) and the respiratory guidance signal (through the auditory senseable signal) match each other, and further let the breath The effect of training has improved. It should be noted that the auditory sensible signal can be generated by the sensible signal generating source, or can be generated by the wearable physiological sensing device, without limitation.

In addition, according to a further aspect, the system of the present invention can also understand the physiological state of the user during the physiological feedback process by detecting physiological signals related to the activity of the autonomic nervous system, as information for immediate feedback to the user. And / or as a basis for adjusting the breathing guide signal. As shown in FIG. 7, in the respiratory physiological feedback system according to the present invention, the wearable physiological sensing device 30 is configured to detect the user's skin electrical activity (EDA, through the electrodes 31 disposed on the two fingers. Electrodermal Activity), this is because skin electrical activity and sweat gland activity Relatedly, the secretion of sweat glands is only affected by sympathetic nerves, and when the sympathetic nerve activity increases, sweat gland activity increases, so the activity of sympathetic nerves can be known by measuring the electrical activity of the skin. In addition, in the system, the sensible signal generating source implements a smart phone 34 to provide the respiratory guided signal and the information required for physiological feedback to the user through the auditory sensible signal. In order to adopt the auditory approach, it is advantageous that the user will be able to select both eyes during physiological feedback, especially when the goal of physiological feedback is to relax the body.

It should be noted that in addition to the fingertips, the skin electrical activity can also be obtained from other locations. For example, the palm, the wrist, etc. are also common locations for obtaining electrical activity of the skin, wherein when the wrist is used to obtain the position, it is preferably The electrode can be implemented as the inner side of the belt body for arranging the housing 32 as shown in Fig. 7 to contact the skin of the wrist, thereby reducing the complexity of the wiring.

Therefore, when performing the physiological feedback program using the system of FIG. 4, the user sets the electrodes on the two fingers to obtain the skin electrical signal, relax the body, and transmit the sound breathing signal and physiological feedback through the mobile phone. Information and adjust your breathing and physiological feedback.

Herein, the auditory sensible signal for expressing the respiratory guidance signal may include, but is not limited to, for example, a time interval for generating an audio signal as a guide for initial inhalation and exhalation; Or a change in volume to represent a continuous change in inspiration and exhalation; or a different sound category to represent inhalation and exhalation, for example, different music tracks, or sound files with periodic changes, such as waves, etc. Allow the user to adjust the breathing as they change; or use the voice to inform the user to inhale or exhale, for example, through the "inhale" and "exhale" voice indications at the time of inhalation and exhalation. User's Breathing mode.

When the auditory sensible signal is simultaneously used to represent the information needed for physiological feedback, there are also many options. For example, the gradual increase or decrease of the sound frequency or volume can be used to indicate an increasingly trending target. Alternatively, the specific sound type, or music, may be used to represent that the target has not been reached, or the target has been reached; or, the voice may be used to inform the user whether the physiological feedback is gradually moving toward the target. Therefore, as long as it can be distinguished from the breathing guide signal, there is no limit.

Therefore, when the goal of physiological feedback is to relax the body and mind, one of the embodiments is to use the sound generated by the interval to guide the user to start inhaling or exhaling, and to use the frequency of the sound to represent the degree of relaxation of the body. For example, the higher the audio, the more nervous it is, and the lower the audio, the more relaxed it is. Therefore, when the user hears a high-frequency hum, you can follow the inhalation and exhalation while learning that you are still too If you are too nervous, you need to find a way to relax. So even with a single voice signal, you can clearly understand the two types of information at the same time.

Alternatively, another embodiment may be to use the strength of the sound volume to represent continuous changes in inspiration and exhalation, and to use different types of sounds to indicate the degree of relaxation of the body, for example, to indicate a higher degree of tension with a bird's voice, and The sound of the waves is more relaxed, and it is also a way to express it clearly.

In addition to detecting physiological activity of the skin for physiological feedback, other physiological signals affected by autonomic nervous activity are also feasible. For example, heart rate is regulated by both sympathetic and parasympathetic nerves, and when sympathetic activity is increased. When the heart rate becomes faster, when the parasympathetic activity increases, the heart rate becomes slower, so the heart rate sequence can be observed to know the difference between the two. In addition, because the blood vessels transmitted to the skin at the end of the limb are only affected by the sympathetic nerves, and when the sympathetic nerve activity is decreased, the vasoconstriction is reduced, the diameter of the blood vessels is increased, the blood flow is increased, and the surface temperature of the skin is increased, so that it is also possible to borrow The temperature sensor detects the peripheral skin temperature of the limb and infers the activity of the sympathetic nerve relative to the parasympathetic nerve. In addition, the muscle tension is also related to the activity of the autonomic nerve. The myoelectric electrode can also be used to obtain the myoelectric signal to detect The muscle tension is measured and the muscle is relaxed. Further, the blood pressure is also related to the autonomic nerve. Therefore, the reference blood pressure can be calculated by changing the blood pressure value or by obtaining the pulse transit time (PTT). The way of value, and the activity of the autonomic nerve is known. Therefore, as long as the physiological signals that can reflect the activity of autonomic nerves are applicable, there is no limit.

Moreover, in the physiological feedback program, the information about the physiological state provided to the user may have other options besides directly expressing the state of relaxation and tension as described above, for example, it may be used for performance calculation. Or the result of the comparison, the effect of physiological feedback, or directly the measured physiological signal.

For example, it may be a rise or fall of the EDA value, whether the sympathetic activity is reduced and/or decreased, or the like; or, further, the immediate physiological state may also be implemented as a physiological state before the respiratory physiological feedback is not performed. The comparison result, that is, the physiological state before the respiratory physiological feedback is taken as a reference, and the present physiological state is presented as a comparison with the reference, for example, an initial skin electrical energy before the respiratory physiological feedback is started. The activity (eg, presented as a resistance value) is considered to be 0. Thereafter, during the physiological feedback of the breathing, the measured electrical activity of the skin is compared with the initial electrical activity of the skin, and when the two are subtracted to obtain a positive value, It means that the resistance value increases, that is, the sympathetic nerve activity decreases, and when the subtraction yields a negative value, it means that the resistance value decreases, that is, the sympathetic nerve activity increases, so in this way, the same can be Enough to present the effects of respiratory physiological feedback on the autonomic nervous system.

When expressing by sound, in addition to various modes such as the above-mentioned sound frequency, volume, sound type, voice, etc., sounds representing physiological states can be generated only when the physiological state meets the conditions, for example, The reference value may be dominant, and the sound representing the physiological state is only when the resistance value is lower than the reference value, that is, when the sympathetic nerve activity is increased and the tension is increased, the warning user is required to relax, and if the resistance value is always high, The reference value indicates that the user continues to be in a relaxed state, and therefore, the sound is not maintained, or vice versa, the sound representing the physiological state continues to be generated, only when the tension exceeds the reference value. It stops, so there is no limit.

Furthermore, visually perceptible signals can be added in addition to auditory perceptible signals as a third type of information, for example, when two physiological signals are detected simultaneously or two physiological information can be obtained. In addition to comprehensively determining the physiological state, the physiological state represented by the two kinds of signals and information may be separately displayed; or, as described above, the actual breathing situation of the user may be indicated to allow the user to Know the difference between your breathing and breathing guide signals. The visually perceptible signal can be provided through an illuminant, a display screen or a device as described above, without limitation.

Further, the breathing guide signal can also be implemented to perform an immediate adjustment according to a change in the physiological state of the user. For example, as described above, when the degree of relaxation of the user has increased and remains stable, the respiratory guidance signal further reduces the breathing rate to further increase the degree of relaxation; or the degree of relaxation of the user has reached the expected level. When the target, or the control of the breath, has steadily matched the breathing guide, the supply of the breathing guide is stopped, and the user can concentrate on self-consciousness regulation, and only find that the breathing is unstable, or the degree of relaxation is lowered. Time, The breathing guide is started again; or the breathing training and physiological feedback are alternately performed by the user through the presence or absence of the breathing guide. Therefore, it can be changed according to the actual use situation, or the user can choose the appropriate method without restriction.

In addition, it should be noted that the sensible signal generating source can be further implemented to be combined with the wearable physiological sensing device, for example, a display component of the wearable physiological sensing device, and/ Or a sounding component to provide visually perceptible signals, and/or auditory perceptible signals, and thus, without limitation. Furthermore, in particular, when the sensible signal generating source is implemented as a separate illuminator as shown in FIG. 1, due to its physically independent characteristics, it can also be implemented by providing a switch, for example , a button, or a dial, or, in particular, by shaking, so there is no limit.

Furthermore, physiological feedback (neurological physiological feedback) and/or breathing training performed by the device according to the invention is also suitable for integration into the game, so that, in addition to changes in visual/auditory effects, for example, changes with physiological state, Colors, object types, people, sounds, etc., through the game, will provide more interactive content, for example, through a game software executed on mobile phones and / or computers, to increase the fun of interaction with users. Sexuality, thereby increasing the willingness to use. For example, first, a score system can be used. For example, if the goal of neurophysiological feedback is to relax the body and mind, the score can be used to express the degree of relaxation in a segment, such as the proportion of alpha waves in the brain wave. Furthermore, since the physiological feedback has a cumulative effect, the scores obtained at different times and in different sections can be cumulatively calculated, so that the user can easily know the results of his efforts through the scores, which is helpful. Develop a sense of accomplishment, and in this case, you can further set the different score thresholds that can be achieved, increase the user's desire for challenge, and, with the concept of the level, when you reach a threshold, you can reach the next level, and Open different functions, etc. Increase the use of fun and increase your willingness to use.

In addition, in addition to the concept of the level, rewards can also be used. For example, when the scores accumulate to a certain threshold, more optional characters can be added. For example, more types of clothes can be replaced, and a halo appears. Etc., or gifts, treasures, etc., or higher levels of gameplay can be promoted, and various methods common to online games are suitable for use in the present invention.

Furthermore, due to the nature of the game, the accumulation of physiological feedback is mainly constructed on the premise of continuous use, that is, when the interval of the physiological feedback program executed is too long, the cumulative effect is lost. For example, the calculation principle of the score can be designed such that the accumulated score will decrease as the time interval becomes longer. If the game is not played for too long, the score will be zero, and the user must start over. For example, when the user does not perform a physiological feedback program 2 days apart, the cumulative score is reduced to 75%, not used 3 days apart, the score is reduced to 50%, and so on, and finally when not used 5 days apart, previously The cumulative score is zeroed to Continuous use by the user.

Therefore, through the game, in addition to making the physiological feedback program more interesting, the user can immediately feel the physiological state change caused by the physiological feedback, so that the user feels that there is a goal and increases the power of use.

It is to be noted that the foregoing embodiments are merely illustrative and not limiting, and that various embodiments may be combined or substituted with each other, and are still within the scope of the present invention.

In summary, according to the physiological feedback system of the present invention, the two processes of respiratory regulation and physiological feedback are novelly combined, and the respiratory guidance signal is introduced into the physiological feedback program. In addition to allowing the spirit to be more concentrated, consciously breathing can affect the characteristics of the autonomic nerves, and the effect of physiological feedback can be more significant. The two complement each other and do more with less. In addition, through the use of physiological feedback information can be provided at the same time. And a single sensible signal of the two kinds of information of the breathing guide signal, and the user can clearly and easily understand the information content in the process of physiological feedback, and the physiological feedback program is more convenient, therefore, the case It does improve the technology of the prior art.
