Description

Light emitting device and physiological feedback system using the light emitting device

technical field

The utility model relates to a light-emitting device and a physiological feedback system using the light-emitting device, in particular to a system combining real-time feedback of physiological information and breathing control.

Background technique

In recent years, more and more studies have focused on how the human body affects the body's operating system through self-consciousness regulation to achieve the effect of improving physical and mental health, such as biofeedback (including neurofeedback) Meditation, breathing training, etc. are all methods that have been supported by a large number of research results and are used by more and more people.

Among them, physiological feedback is a learning process in which the human body learns how to change physiological activities for the purpose of improving health and performance. In this process, the physiological activities in the human body that can be changed through consciousness, such as thinking, emotion, and behavior, For example, brain waves, heart rate, respiration, muscle activity or skin temperature will be monitored by the instrument, and the instrument will quickly and accurately feed back the information to the subject. Since this information is related to the desired physiological change, therefore, After the subject obtains the information, he can carry out self-awareness regulation based on it, and strengthen the required physiological response.

In addition, the common methods of sitting meditation are: focus, mindfulness (mindfulness), and compassion and love, which mainly involve self-consciousness control. The purpose of sitting meditation is consistent with many goals of clinical psychology, psychiatry, preventive medicine and education. More and more research results show that sitting meditation may help relieve symptoms of depression and chronic pain, and help improve overall health. Happiness.

In addition, there is growing scientific evidence that self-awareness regulation during sit-in meditation can change the functional circuits of the brain and have beneficial effects on the mind, brain, and body as a whole, and many neuroscientists have begun Learn about the effects of meditation on the human body by observing how the brain responds during sit-in meditation. And this is similar to the so-called neurophysiological feedback (neurofeedback) to a certain extent, except that when neurophysiological feedback is performed, the information of the brain activity will be provided to the user in real time, just like the physiological feedback.

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

Generally, in the meditation process that requires concentration, it is usually emphasized that the meditator must focus on the rhythm of breathing, especially when the mind wanders, the attention must be refocused on the breathing rhythm of inhalation and exhalation. Therefore, focus Rhythmic breathing is known to enhance concentration.

Breathing is generally controlled by the autonomic nervous system without conscious intervention. It will automatically adjust the breathing rate and depth according to the needs of the body. On the other hand, breathing can also be controlled by consciousness. Within a limited range, The human body can control the breathing rate and depth by itself. Therefore, existing studies have shown that the balance of the sympathetic and parasympathetic nerves can be affected by controlling breathing. Generally, the activity of the parasympathetic nerves increases during exhalation, slowing down the heartbeat, and inhaling. The opposite is true during the gas period.

Therefore, when you need to concentrate on the rhythm of breathing, in addition to achieving concentration and stability by returning your attention to the rhythm of exhalation and exhalation, it will also affect your own autonomic nervous system at the same time. At this point, as long as the effect of breathing on the autonomic nervous system is consistent with the goal of performing physiological feedback, neurophysiological feedback, or meditation, such as relaxation, it is natural to make the effect of physiological feedback more effective due to increased control of breathing. Go up a floor to achieve a complementary effect.

Due to the nature of breathing between conscious and non-conscious control, breathing training is also regarded as a procedure that can improve physical and mental effects by affecting the operation of the human body. Generally speaking, breathing training is the process of adjusting one's own breathing through consciousness. For example, a common breathing training method is Buteyko breathing technique, which advocates breathing through the nose and controlled by consciousness. Breathing methods that reduce the rate or volume of breathing may have a therapeutic effect on diseases caused by increased breathing rate or hyperventilation, such as asthma, or other breathing-related diseases, such as sleep apnea.

In addition, breathing training can also be carried out with an external guiding signal. Usually, the role of the guiding signal is to guide the breathing of the user, for example, guiding the breathing rate, and/or the ratio of exhalation to exhalation time, etc., According to different purposes, the content of the guiding signal can also be changed. For example, when carrying out Butek breathing training, the guiding signal can provide a slower breathing rate to meet the training goal.

Generally, in the process of breathing training, users only focus on the adjustment of breathing, but since the purpose of breathing training is also to improve physical and mental health, if real-time information about the user's physiological state can be provided during the breathing training process, In order to let the user know whether the breathing adjustment is moving towards the expected goal, it is believed that it will help to further improve the efficiency of breathing training and achieve twice the result with half the effort.

Therefore, it is indeed necessary to develop a novel system that can provide a basis for further breathing adjustment when the user performs physiological feedback, meditation, or neurophysiological feedback through self-consciousness control, so that breathing can play a role in improving physical and mental health. Influences can be exhibited simultaneously, which in turn complement each other to increase the achievable effect.

In addition, when based on breathing training, it is also possible to let users know their own physiological state in real time, so that users can change their breathing behavior or other physiological conditions through self-conscious regulation while performing breathing training. state to further enhance the effect of training.

Detailed ways

The purpose of the system of the present utility model is to integrate the program that affects the physiological state through self-consciousness adjustment and breathing control into the same training section, and realize the acceleration by interacting with the user to form a feedback loop. Therefore, it can be widely used in physiological feedback, neurophysiological feedback, meditation, and/or breathing training, etc., which affect the physiological state through self-consciousness regulation, so that the effect of the program can be further improved. Get a boost.

Under this principle, the system according to the present invention has a wearable physiological sensing device and a perceivable signal generating source, wherein the wearable physiological sensing device is used to obtain the physiological activity occurring in the training section. The physiological signals affected by the change, and the perceivable signal generation source are used in the training section, through the user's perceivable signals, for example, visually perceivable signals and/or auditory perceivable signals, to provide feedback to the user. Provide breathing guidance and information about physiological activities, such as real-time physiological status, changes in breathing behavior, and/or effectiveness of training execution, etc.

Please refer to Fig. 1, which shows a preferred embodiment of the system according to the present invention, this embodiment is to provide the implementation content of the integration of the neurophysiological feedback system into breathing training, therefore, here, the wearable physiological sensing device is It is implemented as a head-mounted EEG detection device 10 , and the perceivable signal generation source is implemented as a luminous body 12 .

When the user uses the neurophysiological feedback system of the present utility model to perform a neurophysiological feedback program, as shown in the figure, the head-mounted EEG detection device is arranged on the head to pass through the inner side of the headband The EEG electrodes obtain the user's brain waves. Here, the location of the EEG electrodes is not limited, as long as it is a corresponding sampling point at a specific cerebral cortex position where the brain waves can be obtained. For example, common sampling points include Fp1, Fp2, O1, O2, etc., or any position defined according to the 10-20 system, and the location and number of EEG electrodes can be determined according to the purpose of neurophysiological feedback, for example, the number of electrodes can be increased For the measurement of multi-channel EEG signals, electrodes may be set on the ears as reference points, etc., therefore, there is no limitation.

Afterwards, the luminous body 12 is arranged in the position where the eyes can see naturally in front of the body, and the EEG detection device on the head communicates with the luminous body, for example, through general wireless communication methods such as bluetooth, WiFi, etc., that is, The respiratory physiologic feedback program can begin.

Here, due to the combination of breathing training and neurophysiological feedback, based on the breathing training, it is necessary to provide the user’s breathing guidance signal, and based on the neurophysiological feedback, it is necessary to provide the user’s response to the execution of neurophysiological feedback. Physiological activity information and/or other relevant information, and the luminous body is the medium provided.

In this embodiment, the signals generated by the luminous body that can be perceived by the user include luminous intensity and luminous color to represent different information respectively, wherein the luminous intensity is used to express breathing guidance, while the luminous color is used to represent breathing guidance. Show 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 needs to be able to show the difference between inhalation and exhalation. Therefore, the luminous body represents inhalation and exhalation through continuous changes in the intensity of the light. Continuous change, for example, gradually increasing luminous intensity as a guide for gradually inhaling, and gradually decreasing luminous intensity as a guide for gradually exhaling, so that the user can clearly and easily follow and perform inhalation and exhalation.

When doing a neurophysiological feedback program aimed at relaxation, one option is to look at the proportion of alpha waves in your brain waves. In brain waves, generally speaking, when α waves are dominant, it means that the human body is in a relaxed and awake state, so the degree of relaxation can be known by observing the proportion of α waves. Accordingly, after starting the neurophysiological feedback program, the luminous body provides breathing guidance (through continuous changes in luminous intensity) to guide the user to adjust his breathing. At the same time, the EEG detection device worn on the head also performs The detection of brain waves, and the obtained brain waves are calculated by a calculation formula, and an analysis result can be obtained, for example, the proportion of α waves, and according to the analysis results, a relevant user's brain activity can be generated. Then, the luminous body changes its light color according to the information about the brain activity of the user.

For example, a baseline value can be obtained at the beginning of the program, for example, the percentage of α waves in the total brain wave energy, and then the analyzed results are compared with the baseline value to obtain a comparison with the baseline value. relationship between them, for example, the ratio increases or decreases, and based on this, the luminous body can convey the change of its physiological state to the user in real time through the change of the luminous color. For example, it can be expressed by using multiple colors, such as Closer to blue means more relaxed, closer to red means more tense. It can also be based on the depth of the same color. The lighter the color, the more relaxed, and the darker the more tense. In this way, the user can easily pass the color You can know whether your physical and mental state is tense or relaxed, and follow the breathing guidance while also performing self-regulation, so that the luminous color will further tend to a more relaxed goal.

Alternatively, the level of relaxation or emotional awareness of the body can be understood by observing the energy balance and synchrony of brain activity between the two hemispheres; or, the brain activity can be detected by measuring the amount of blood flow in the cerebral cortex The degree of exuberance to judge the degree of physical and mental relaxation.

In addition, when the goal is to improve concentration, you can choose to observe the ratio of theta waves to beta waves. In brain waves, when the β wave is dominant, it means that the human body is in a state of wakefulness and tension, while when the θ wave is dominant, it means that the human body is in a state of relaxation and interruption of consciousness. Therefore, by increasing the ratio of the β wave to the θ wave, To achieve the purpose of improving concentration, for example, one of the methods for treating ADHD (Attention deficit hyperactivity disorder) patients is to observe the ratio of theta wave/beta wave through neurophysiological feedback. Accordingly, after the neurophysiological feedback program is started using the system of the present invention, the luminous body provides a breathing guidance signal (through continuous changes in luminous intensity) to guide the user to adjust his breathing, and at the same time, it is worn on the head The EEG detection device also detects brain waves to further analyze the ratio of θ waves and β waves, for example, the ratio of θ waves and β waves to the total brain wave energy, or calculate θ/θ+β and β /θ+β, etc. After that, according to the analysis results, information about the brain activity of the relevant user is generated, and the luminous body is based on the information about the brain activity of the relevant user, and is transmitted to the user in real time through the change of the luminous color. The user communicates the change of his brain function. For example, it can be represented by a variety of colors. The closer to blue, the lower the concentration, and the closer to red, the higher the concentration. It can also be based on the depth of the same color. Lighter means lower concentration, and darker color means higher concentration. In this way, users can easily know whether their concentration has improved through the change of color, and follow the breathing guidance at the same time Carry out self-regulation, and make the luminous color further tend to improve the goal of concentration.

In addition to observing the ratio of θ waves to β waves, cortical slow potential (SCP, slow cortical potential) is also a brain activity that is often observed in neurophysiological feedback that improves concentration. Among them, the negative shift of SCP is related to Greater concentration, and positive shift of the SCP correlates to decreased concentration.

Therefore, the physiological state represented by the luminous color can be implemented in various ways, for example, the converted degree of relaxation or concentration can be used as the basis for change as described above, or it can be used to represent the change of a single physiological signal, such as , changes in the proportion of alpha waves, or changes in brain activity, etc., therefore, there is no limit. Moreover, there is no certain limit to the way of changing the luminous color. The key point is to allow users to understand their own physiological state simply and clearly, and to drive the user to carry out self-consciousness regulation to achieve the target physiological state.

In addition, alternatively, the luminous color can also be used to represent other information related to the use status, for example, it can be used to represent the accumulated training hours, for example, the darker the color, the longer the accumulated training time, so that the user can The reader understands the cumulative effect brought by the physiological feedback program with a cumulative effect, and here, the cumulative time can be a cumulative period of time, for example, within a week, or the time of the current training, etc., can be determined according to the user or, the luminous color can also be used to indicate the time start of each training section, for example, the light color at the beginning gradually becomes darker to indicate that the training is gradually approaching the end. Therefore, all are feasible methods without limitation.

Furthermore, the luminous body can also be implemented to set the time of the training section, for example, 10 minutes, 15 minutes, and automatically shut down when the time is over, so that the user can concentrate more on breathing control and exercise. Self-awareness control is more conducive to the achievement of the target effect.

Therefore, through the system of the present utility model, the user can naturally combine breathing control and the procedure of affecting the physiological state through self-consciousness control without special learning steps, and the very important reason is that the perceivable signal generation source The generated perceptible signal includes two kinds of information. For example, in the embodiment shown in FIG. 1, the visually perceivable signal generated by the single luminous body expresses two kinds of breathing guidance signal and real-time physiological state respectively through luminous intensity and luminous color. information.

In the prior art, when neurophysiological feedback is performed, the feedback method for the user is usually implemented as, for example, a moving object is generated as the performance of the physiological feedback is performed, for example, a balloon floating in the air, when When the body is more relaxed, the balloon floats higher; or graphics that change with the physiological state, for example, flowers that will continue to bloom as the body becomes more and more relaxed; or directly display changes in measured values; and provide breathing guidance The method of induction is mostly implemented as, for example, representing inhalation and exhalation through up and down waveforms. Therefore, when the two are combined, the user is likely to be disturbed by the visual display of values that are too complex, too variable, or difficult to understand, and may even increase the user's mental stress, and the effect will not increase but decrease.

In addition, there is also a prior art, as shown in U.S. Patent Application No. US6212135, which guides the user through exhalation, expiratory pause, inhalation, and inspiratory pause during breathing training through the form of a luminous body. However, the way it describes can only show the breathing behavior pattern for the user to follow, and cannot let the user know the impact of the breathing training 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, when the utility model considers how to provide information to the user, it chooses the method of expressing two kinds of information through a single object, which simplifies the complexity as much as possible and prevents the user from being mentally disturbed. burden, but also allows users to use the system very easily. The advantages of the display method disclosed by the utility model include:

1. The size change of luminous intensity is similar to the expression of general rhythm and rhythm. The user can intuitively obtain guidance and control inhalation and exhalation without thinking about conversion.

2. Luminous color is an easy-to-understand representation of physiological status for users. Compared with directly providing numerical changes, the human body can easily agree with the use of color types and/or changes in depth to indicate changes in degrees and levels. Feelings, and thus respond more naturally to make self-aware regulation.

3. There is only one focus of vision, and there is no need to pay attention to two focuses when combining two programs, which is more helpful for concentration.

Therefore, the possible complexity of combining the two programs can be eliminated through the well-designed perceptible signal expression, which not only effectively reduces the burden on the user when using it, but also realizes the novelty of effect bonus. Feedback Program.

During implementation, the illuminant can have various implementation options. For example, in terms of appearance, it can be a sphere as shown in Figure 1, or it can be other shapes such as square and pyramid, and further, it can also be implemented It is a form of floating through magnetic force, which increases the fun of use; in addition, in addition to implementing the entire illuminant to emit light, it can also be implemented to only partially emit light. As shown in Figure 2A, the illuminant is arranged on the top through the A light-transmitting part of the body can exhibit its luminous behavior, and the light-transmitting part can also be implemented in different shapes to arouse the user's interest, for example, a multi-level concentric ring (Figure 2B), or a radial shape (FIG. 2C), etc., without limitation.

In addition to using a single luminous body to provide luminous intensity and luminous color changes, it can also be realized by other devices with display functions. For example, it can be a light source on a screen, such as a tablet computer, mobile phone, Watches, personal computer screens, etc. Further, the light source can also be implemented as a part of the image, for example, the head of a human figure image, or the position of the abdomen, etc., which helps the user to imagine the activities in the body during self-consciousness regulation, In addition, in addition to the form of a physical light source, the aperture is also a good implementation form, for example, the aperture around the humanoid head also helps the user to imagine. And when it is implemented as the above-mentioned light source or aperture on the screen, the change of luminous intensity can be further represented by the change of the diameter of the luminous range, as shown in FIG. 2D , so as to enhance the effect of guiding inhalation and exhalation. Therefore, it can be changed according to actual implementation conditions without limitation.

In addition, the system according to the present invention can also additionally provide auditory perceptible signals, such as sound or voice, so as to provide another option when the user needs to close the eyes to perform the feedback procedure. Intensity represents the continuous change of inhalation and exhalation, and represents different physiological states through different sound types, such as bird calls, ocean waves, etc., or different tracks; or, the user can also be instructed to inhale and exhale by voice. Exhale, and the physiological state is represented by the sound frequency. For example, the higher the frequency, the more tense the sound, and the lower the frequency, the more relaxed. Therefore, there is no limit. Also, the auditory perceptible signal can be provided by the perceivable signal generating source and/or the wearable physiological sensing device, also without limitation.

Still further, the breathing guide signal can also be adjusted in real time according to changes in the physiological state of the user. In general breathing training, the types of breathing guidance signals are mainly divided into three types, one is the preset fixed breathing change mode, for example, the breathing rate is set to be fixed at 8 times per minute; the other is the preset breathing that changes with time Varying patterns, e.g., in a 15-minute training segment, the breathing rate is set at a rate of 10 breaths per minute for the first 5 minutes, 8 breaths per minute for the middle 5 minutes, and 6 breaths per minute for the last 5 minutes; and One is the breathing change pattern that changes dynamically with the physiological state. Therefore, in the present utility model, in addition to providing the breathing guidance signal which is preset to be fixed and changes with time, the physiological signal obtained by the wearable physiological sensing device, for example, the embodiment in FIG. 1 Based on the EEG signal obtained by the EEG detection device, the breathing guidance signal can be implemented to dynamically change with the physiological state, so as to provide a breathing change pattern that more effectively guides the user towards the target physiological state.

There are many options for how the physiological state of the user affects the breathing guidance signal. For example, when the user's relaxation level has increased and remained stable, the breathing guidance signal can be implemented to further reduce the breathing rate, for example, from 8-10 breaths per minute to 6-8 breaths per minute to further Increase the degree of relaxation; or, it can also be implemented as when the user's relaxation degree has reached the expected target, or when the breathing control has been stably consistent with the breathing guide, the provision of the breathing guide signal is stopped, so that the user can focus For self-awareness control, only when the breath is found to be unstable again, or the degree of relaxation is reduced, the breathing guidance is started again, so there is no limit.

Furthermore, in particular, it can also be implemented as a program that allows the user to alternately perform breathing control and change the physiological state through self-awareness control through the presence or absence of the breathing guidance signal. As mentioned above, according to research, when performing procedures that affect physiological states through self-consciousness regulation, especially neurophysiological feedback and meditation, if breathing can be in a smooth and stable state, the effect of feedback can be obtained. Addition, therefore, let the user get used to the breathing pattern by intermittently providing the breathing guidance signal for a period of time to achieve the stability of breathing, and then by stopping the breathing guidance, let the user continue the habitual breathing mode naturally Simply focusing on the self-awareness regulation process in the breathing mode will further enhance the effect of feedback.

Moreover, since breathing training has a delayed response to the influence of autonomic nerves, by intermittently providing guidance signals, combined with the characteristics of the utility model in combination with breathing training and self-awareness control programs, it can be achieved without providing breathing guidance. During the period when the effect of breathing training on the autonomic nerves is displayed, it is convenient for the user to carry out the self-awareness regulation procedure, so that the effect of the training can be increased.

Here, the alternation between breathing training and self-awareness control procedures, that is, whether or not breathing guidance signals are provided, can be determined according to the physiological state of the user as described above, or it can be based on a preset time interval, Toggling is done on a fixed basis with no limit. In addition, when a fixed switching method is adopted, it can be further implemented that the breathing guidance signal is switched between fast and slow breathing rates, for example, 6-8 times per minute and 10-12 times per minute, and such The method can help, for example, focus switching training to achieve more flexible control.

Here, it should be noted that besides the head-mounted form shown in Figure 1, the wearable structure for obtaining EEG signals can also be implemented in other forms, as shown in Figure 3. The embodiment of the electrodes. In this example, the EEG electrodes can pass through the ear-worn structure and the skin of the ear or the area near the ear to obtain EEG signals. Therefore, it is also a very convenient way and has no limitation.

Next, according to the idea of another aspect of the present invention, the detection of the user's breathing behavior can also be used as a basis for providing information about the user's physiological state. As shown in FIG. 4A , the user performs a breathing training program through a respiratory motion sensing element 20 arranged on the abdomen and a screen with a light source 22 placed in front of the body, wherein the function of the respiratory motion sensing element is to feel breathing The body cavity rises and falls caused by the movement, so the information that can be provided includes, but is not limited to, the duration of exhalation, expiratory pause (exhalation pause), inspiration and inhalation pause (inhalation pause), respectively, respiratory rate, whether the user uses abdominal or Chest breathing (that is, the gas mainly causes the abdomen or chest to expand during inhalation), ventilation volume (the so-called depth of breathing), and control pause time, etc. Here, the respiratory motion sensing element that can be used Including, but not limited to, RIP bandage (Respiratory Inductance Plethysmography (RIP, respiratory induction plethysmograph) effortbelt), and piezoelectric respiratory bandage (piezorespiratory effortbelt), etc.

Therefore, when the breathing training program is performed through the system shown in Figure 4A, one form that can be implemented is to provide the difference between the user's own actual breathing behavior pattern and the breathing guidance signal as a guide for the user to perform self-consciousness regulation. According to, for example, the difference between the two can be obtained by calculating the score, for example, the difference between the user's actual breathing behavior pattern and the guidance signal can be calculated through a preloaded calculation formula, for example, it can be used for breathing rate, the ratio of exhalation period/inhalation period, etc., the higher the score, the smaller the difference, and the lower the difference, the greater the difference, and then use the color change to indicate the score level, for example, the same color shade or different colors The continuous change of represents the level of the score, so that users can know it in real time and make real-time adjustments.

Another possible form is to provide information about the user's breathing 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, knowing the information about the stability of one's own breathing can also help the user to regulate self-awareness, for example In other words, the presentation method of the stability can be expressed as a score as mentioned above. For example, the rate of change of the breathing rate can be calculated through a preset calculation formula. For example, it is calculated every 1 minute. The lower the rate of change indicates the degree of stability The higher the score is, the higher the score will be, and the luminous color will be changed accordingly, or the score can be obtained by observing the stability of the breathing amplitude, or the feedback can be based on the comprehensive evaluation of the breathing rate and the breathing amplitude; Changes in respiration rate or respiration amplitude can be directly represented by the glow color, so there is no limitation.

Yet another form of implementation is to provide information about changes in ventilation. Usually, when performing breathing training, in addition to the breathing rate, the size of the ventilation volume 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 Being able to maintain a steady and not too large ventilation also helps to keep the body and mind in a relaxed and stable state, so it can be used as a basis for users to self-adjust by providing information about the ventilation during breathing. For example, a standard value can be preset, and the result of comparison with the standard value can be presented to the user through the luminous color. The color changes only when the standard value is changed, or, the darker the luminous color, the more it exceeds the standard value, and the lighter the color, the closer to the standard value; To the size of ventilation.

Yet another practicable form is to provide information about the user performing abdominal breathing, or chest breathing. Studies have pointed out that the use of abdominal breathing helps to increase the activity of parasympathetic nerves, which can further strengthen the effect of affecting the autonomic nerves to relax the body and mind. Therefore, when the breathing 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 breathing motion sensing element can be set separately from the abdomen to understand the ups and downs of the abdomen, or the breathing can be set separately from the chest. Motion sensing element, to know whether there is a rise and fall in the chest (under the premise of wishing to carry out abdominal breathing), or as shown in Figure 4B, the breathing motion sensing element 20 is respectively arranged on the chest and abdomen; in addition, some abdominal breathing Training requires breathing on specific parts, for example, the upper abdomen or lower abdomen, and this can be achieved by adjusting the position of the breathing action sensing element on the abdomen to meet the detection requirements for different parts. When providing user-related information, for example, the luminescent color can be used to indicate the ventilation volume detected by the breathing action sensing element installed on the abdomen, or it can also indicate the ventilation volume detected by the breathing action sensing element installed on the chest. Whether or not the element detects the expansion of the chest, or can also represent the ratio of the degree of expansion of the abdomen to the chest, etc., therefore, there is no limitation.

In addition, another kind of information that can be provided is information about whether the user breathes through the nose and/or the mouth. Generally speaking, the best breathing method is to breathe through the nose. When the mouth participates in breathing, or only through the mouth, since the ventilation volume will be greater than that through the nose alone, it will easily cause overbreathing. When air is inhaled through the nose, the air is heated and humidified, while the hairs of the nose and the cilia inside the nose filter out particles and prevent them from entering the lungs. According to reports, many people only breathe through the mouth unconsciously. Therefore, it only needs to consciously change this situation to return to breathing through the nose. Therefore, it is also helpful to provide such information during breathing training. To allow users to breathe in a more correct way and improve the effect of training. When providing user-related information, for example, the user can know the presence or absence of oral air flow, and/or the relationship between nasal air flow and oral air flow during breathing training through color changes. The proportion of flow, etc., can be changed according to actual needs. Here, in order to distinguish the respiratory air flow of the mouth and nose, it is necessary to use a sensing element that can detect changes in the outlet and nasal airflow, for example, a respiratory airflow tube or an oronasal tube, which can detect changes in the mouth and nose respiratory airflow, and The thermal sensor placed between the mouth and nose can sense the temperature change of the respiratory airflow, etc.

Furthermore, since breathing affects the autonomic nervous system, the heartbeat that is also controlled by the autonomic nervous system changes, which is the so-called sinus arrhythmia (Respiratory Sinus Arrhythmia, RSA), that is, the heartbeat accelerates during inhalation and Breathing slows down the heartbeat. Therefore, another way to obtain the user's breathing behavior is to measure the heart rate. Generally speaking, when the respiration and the heartbeat are synchronized with each other, the respiration change can be obtained by analyzing the heart rate sequence.

Common ways to obtain heart rate series include, but are not limited to, obtaining heart rate series by detecting arterial pulses, for example, light sensors placed on ears, fingers, wrists, foreheads, etc., pressure sensors placed directly on arteries, and Arterial pulses can be obtained from cuffs, etc. Here, the optical sensor refers to a sensor that has a light-emitting element and a light-receiving element, and uses the principle of PPG (photoplethysmography, photoplethysmography) to obtain light signals. In addition, the heart rate series can also be obtained by measuring the ECG, for example, by setting at least two cardiac The electrocardiogram is obtained by using the electrodes, as shown in Fig. 5A, an embodiment of obtaining electrocardiographic signals through two finger-worn electrocardiographic electrodes, Fig. 5B shows an embodiment of obtaining electrocardiographic signals by touching ears and wrists, and Fig. 5C It shows an embodiment in which ECG signals are obtained by touching the exposed ECG electrodes of the ear-worn device hung on the ear with the hand. Therefore, there are various options and can be changed according to actual use requirements without limitation.

Therefore, according to another aspect of the present invention, the information provided to the user through the luminous color may also include a lot of information related to the autonomic nerve derived from heart rate and RSA information. For example, according to research, Better harmony and synchronization between breathing and heart rate represents a more orderly and coordinated heart rhythm, that is, the human body is in a relatively relaxed and stable state. Therefore, it can be used by analyzing the harmony and synchronization between breathing and heart rate. To judge the effectiveness of breathing guidance training and/or as real-time information to provide users, for example, frequency domain analysis can be performed on heart rate series. When the frequency spectrum is more concentrated, it means that the synchronization between the two is higher, or it can also be calculated. The smaller the phase difference, the higher the synchronization between the two. Therefore, the analysis results of the harmony or synchronization can be presented to the user through the shade of the same color and the change of different colors, for example , the lighter the color, the higher the harmony/synchronization, and the more relaxed the body. On the contrary, the darker the color, the lower the harmony/synchronization, so that the user can know the breathing training/physiological feedback they are doing in real time Whether to move toward the goal of relaxation; moreover, the breathing guidance signal can be adjusted through the analysis results to further guide the user's breathing, so that the physical and mental state gradually tends to a more relaxed goal.

Alternatively, as shown in FIG. 4C , an ECG electrode 24 is re-set in the respiratory action sensing element, and the heart rate sequence is obtained from the electrocardiogram, and then matched with the related respiratory behavior obtained by the respiratory action sensing element. Information can also obtain the above-mentioned analysis results of harmony and synchronicity, so there is no limitation.

Furthermore, since the RSA information can be obtained through the heart rate sequence, the synchronization among the heart rate, respiration, and EEG signals can also be observed as a basis for feedback. According to research, exhalation and inhalation will cause blood volume fluctuations in blood vessels, and this fluctuation will also reach the brain along with the blood flow, thereby causing brain waves to be in the low frequency range close to the breathing rate, for example, below 0.5 Hz , the fluctuation, therefore, in addition to knowing whether the synchronization between the two is achieved due to the resonance effect, the breathing pattern can also be known by observing the brain wave. Moreover, the autonomic nervous system will also feed back changes in heart rate and blood pressure to the brain through the baroreceptor system, thereby affecting the function and operation of the brain, for example, affecting the cerebral cortex, and can be controlled by EEG It is measured in the figure, and consciously controlling breathing can cause heart rate changes due to the influence of the autonomic nerves. Therefore, there is a relationship between the three influencing each other. Therefore, a good synchronization between the three can represent that the human body is in a relatively relaxed state. According to this, the analysis result of the correlation synchronization can also be used as information to provide the user with self-consciousness adjustment for neurophysiological feedback.

Therefore, as shown in FIG. 6, the optical sensor can be combined with the head-mounted EEG detection device in FIG. The heart rate sequence is obtained from the forehead on the inside of the headband. In this way, through more kinds of physiological signals, it will be possible to have a more accurate assessment of the user's physiological state, and naturally provide real-time information that is closer to the actual physiological state. So that the user can move towards the target physiological state more easily.

In addition, in addition to the common purpose of relaxing the body and mind through breathing training, other purposes can also be achieved by regulating breathing. For example, since the RSA amplitude is related to the activity of the parasympathetic nerve, a larger RSA amplitude represents better parasympathetic nerve activity. activity, and when the parasympathetic nerve activity increases enough, the body's relaxation response (RelaxationResponse) can be triggered to release the accumulated stress. The guide informs the user that it is possible to inhale, and when the heart rate begins to slow down, the breathing guide informs the user that it is possible to exhale, so as to achieve the effect of increasing the RSA amplitude. The breathing guidance signal that triggers the human body's relaxation response; at this time, in conjunction with, for example, the luminous color indicating whether the user's breathing matches the breathing guidance signal, or the information of whether the parasympathetic nerve activity has increased, etc., will be able to Further improve the effect of breathing guidance. In addition, because the magnitude of the amplitude obtained by the peak and trough of RSA, that is, the difference between the maximum value and the minimum value of the heart rate in a breathing cycle, will be related to the activity of the autonomic nerve. Therefore, it can also be This information is provided to the user in real time as a basis for the user to adjust physiological activities.

Further, after obtaining the heart rate sequence, HRV (HeartRateVariability, heart rate variability) analysis can also be carried out, and HRV analysis is a common means of knowing the activity of the autonomic nervous system, for example, frequency domain analysis (Frequency domain) can be performed , to obtain the total power (TotalPower, TP) that can be used to evaluate the overall heart rate variability, the high frequency power (High Frequency Power, HF) that can reflect the parasympathetic nerve activity, and the Low frequency power (Low Frequency Power, LF), and LF/HF (low frequency power ratio) that can reflect the active balance of sympathetic/parasympathetic nerves, etc., can also be obtained by observing the state of frequency distribution after performing frequency analysis The harmony of autonomic nerve operation; or, time domain analysis (TimeDomain) can also be performed to obtain SDNN which 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, and which can be used as a short-term overall heart rate variability RMSSD, which is an index of heart rate variability, and R-MSSD, NN50, and PNN50, which can be used to evaluate the high-frequency variation of heart rate variability.

Therefore, the results of HRV analysis can also be provided to the user in real time through the change of the luminous color, as information for the user to know the activity of the autonomic nerve. Analysis, therefore, real-time HRV analysis can be implemented through the concept of moving window (MovingWindow), that is, first determine a calculation time period, for example, 1 minute or 2 minutes, and then, by continuously moving this time The method of moving the section backwards, for example, calculating once every 5 seconds, can continuously obtain the HRV analysis results, for example, obtaining an HRV analysis result every 5 seconds, thus achieving the purpose of providing real-time HRV analysis results. In addition, it can also The concept of weighting is used to moderately increase the calculation proportion of physiological signals closer to the analysis time, so that the analysis results are closer to real-time physiological conditions.

Moreover, according to the idea of another aspect of the utility model, through the physiological sensor that can detect the breathing behavior of the user, the system according to the utility model can also be implemented to provide the user with his own breathing behavior pattern, so that the user can know his own breathing behavior. The actual breathing situation, for example, can provide the actual breathing rate of the user, and the change of the exhalation period/inhalation period, etc. through the continuous change of the luminous intensity. At this time, the real-time physiological state information provided by the luminous color may have different possibilities according to the different physiological sensors of the user. For example, it may also be related to breathing behavior information, for example, it may be the breathing rate Changes, breathing stability, the ratio of exhalation to inhalation, the size of ventilation volume, whether it conforms to abdominal breathing behavior, changes in mouth/nasal air flow, etc.; in addition, it can also be other physiological information, For example, when the heart rate sequence is obtained for analysis, the breathing behavior pattern of the user can be obtained on the one hand, and other physiological state information such as the aforementioned autonomic nervous activity and RSA-related information can be obtained on the other hand; or, The physiological state information is obtained through another physiological sensing element, for example, the brain activity is obtained by obtaining the EEG signal at the same time, so there is no limitation.

In addition to the above-mentioned possibilities, it can also be implemented to provide a comparison result of the difference between the user's actual breathing pattern and the breathing guide signal and a preset grading table. For example, the preset grading table can provide As a comparison benchmark for the difference between breathing rates, for example, the difference is divided into blue: 0-20%, green: 20-40%, yellow: 40-60%, red: 60-80%, therefore, the user You can know the difference between your own breathing and the breathing guide signal through the displayed color, and then adjust your breathing.

Furthermore, in this case, a breathing guidance signal, such as sound or voice, can also be provided through an auditory perceptible signal, so as to serve as an adjustment function for the user in addition to the physiological state information presented by the luminous color. The basis of their own breathing behavior patterns, and/or let the user know whether their breathing (shown through luminous intensity) and breathing guidance signals (shown through auditory perceptible signals) are consistent with each other, and further Improve the effect of breathing training. Here, it should be noted that the auditory perceptible signal can be generated by the perceivable signal generating source, or by the wearable physiological sensing device, without limitation.

In addition, according to another aspect of the conception, the system of the present invention can also understand the physiological state of the user during the physiological feedback program by detecting the physiological signal related to the activity of the autonomic nervous system, as real-time feedback information to the user, and / or as a basis for adjusting the breathing guidance signal. As shown in Figure 7, in the respiratory physiological feedback system according to the present utility model, the wearable physiological sensing device 30 is implemented to detect the user's electrodermal activity (EDA, Electrodermal Activity) by electrodes 31 arranged on two fingers. ), this is because the electrical skin activity is related to the activity of sweat glands, and the secretion of sweat glands is only affected by the sympathetic nerve, and when the sympathetic nerve activity increases, the sweat gland activity increases, so the sympathetic nervous system can be known by measuring the electrical skin activity. activity increase or decrease. In addition, in this system, the perceivable signal generation source is to implement a smart phone 34, so as to provide the breathing guidance signal and the information required for physiological feedback to the user through the auditory perceivable signal, and when implemented as Advantageously, when using the auditory method, the user will have the option to close the eyes during the physiological feedback, which is especially beneficial when the goal of the physiological feedback is to relax the body.

It should be noted that in addition to fingertips, electrodermal activity can also be obtained from other locations, for example, palms, wrists, etc. , then the electrodes can be implemented to be disposed on the inner side of the belt used to set the housing 32 as shown in FIG. 7 to contact the skin of the wrist, which can also reduce the complexity of wiring.

Therefore, when using the system in Figure 4 to perform a physiological feedback program, the user places electrodes on two fingers to obtain skin electrical signals, relaxes the body, and uses the voice breathing guidance signal and physiological feedback information presented by the mobile phone And adjust your breathing and give physiological feedback.

Here, the auditory perceptible signal used to represent the breathing guidance signal may include, but not limited to, for example, the time interval of generating the sound signal can be used as a guide for the initial inhalation and exhalation; the sound frequency can be used Or volume changes to represent the continuous change of inhalation and exhalation; or different sound types can represent inhalation and exhalation, for example, different music tracks, or sound files with periodic changes, such as the sound of ocean waves, etc., so that The user adjusts the breathing as it changes; or it can also tell the user to inhale or exhale through voice, for example, guide through the voice instructions of "inhale" and "exhale" at the time points of inhalation and exhalation The breathing pattern of the user.

And when the auditory perceptible signal is used to express the information required for physiological feedback at the same time, there are also many options. For example, the gradual increase or decrease of the frequency or volume of the sound can be used to indicate that the goal is getting closer , or, a specific sound type or music can represent that the target has not been reached or has been reached; or, the user can also be notified by voice whether the progress of the physiological feedback is gradually approaching the target. Therefore, there is no limitation as long as it can be distinguished from the breathing guide signal.

Therefore, when the goal of physiological feedback is to relax the body and mind, one of the implementation methods is to use interval beeps to guide the user to start inhaling or exhaling, and use the sound frequency to represent the degree of body relaxation , for example, the higher the tone, the more nervous it is, and the lower the tone, the more relaxed it is. Therefore, when the user hears the high-frequency beep, they can follow the inhalation and exhalation while knowing that they are still If you are too nervous, you need to find a way to relax your body and mind. Therefore, even through a single sound signal, the user can clearly understand two kinds of information at the same time.

Alternatively, another implementation may be to use the strength of the sound volume to represent the continuous change of inhalation and exhalation, and to use different types of sounds to indicate the degree of relaxation of the body, for example, to express a higher degree of tension with the sound of birds, The sound of ocean waves is more relaxing, which is also a way to express clearly.

In addition to physiological feedback by detecting electrical skin activity, other physiological signals affected by autonomic nerve activity are also feasible. For example, heart rate is regulated by both sympathetic and parasympathetic nerves, and when sympathetic nerve activity increases , the heart rate becomes faster, and when the activity of the parasympathetic nerve increases, the heart rate slows down, so the activity of the two can be known by observing the heart rate sequence; in addition, because the blood vessels sent to the skin of the extremities are only affected by the sympathetic nerve, And when the sympathetic nerve activity decreases, the vasoconstriction decreases, the diameter of the vessel becomes larger, the blood flow increases, and the skin surface temperature rises. Therefore, the temperature sensor can also be used to measure the skin temperature of the extremities to infer the increase or decrease of the activity of the sympathetic nerve relative to the parasympathetic nerve. In addition, the degree of muscle tension is also related to the activity of the autonomic nerve, and the electromyographic signal can also be obtained by using the electromyographic electrode to detect the tension of the muscle, so as to know the state of muscle relaxation; moreover, the level of blood pressure is also related to the autonomic nerve, Therefore, the activity of the autonomic nerve can be known through the change of the blood pressure value or the method of calculating the reference blood pressure value by obtaining the pulse transit time (PTT). Therefore, as long as the physiological signals that can reflect the activity of the autonomic nervous system are applicable, there is no limitation.

Moreover, in the physiological feedback program, the information about the physiological state provided to the user, in addition to directly showing the state of relaxation and tension of the body as mentioned above, there are other options, for example, it can be used to express the calculated Or the result of comparison, the effect of physiological feedback, or the direct representation of the measured physiological signal.

For example, it can be the rise or fall of the EDA value, whether the sympathetic nerve activity is reduced and/or the degree of reduction, etc.; or, further, the real-time physiological state can also be implemented as the same as the physiological state before breathing physiological feedback. The comparison result, that is, the physiological state before the respiratory physiological feedback is used as a benchmark, and the presentation of the real-time physiological state is the comparison difference with the benchmark, for example, an initial skin galvanic state before the respiratory physiological feedback is started The activity (e.g., presented as a resistance value) is regarded as 0, and then, during the breathing physiological feedback period, the measured electrodermal activity is compared with the initial electrodermal activity, 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 results in a negative value, it means that the resistance value decreases, that is, the sympathetic nerve activity increases. Therefore, in this way, the respiratory physiology can also be presented. The effect of feedback on the autonomic nervous system.

When expressing through sound, in addition to the above-mentioned various methods such as sound frequency, volume, sound type, voice, etc., it can also be implemented that the sound representing the physiological state is only produced when the physiological state meets the conditions, for example , it can be based on the reference value, and the sound representing the physiological state will only appear to warn the user to relax when the resistance value is lower than the reference value, that is, when the sympathetic nerve activity increases and the tension increases. If it is higher than the reference value, it means that the user continues to maintain a relaxed state, therefore, maintains no sound, or, on the contrary, it can be implemented that the sound representing the physiological state is continuously produced, and only when the tension exceeds the reference value , so there is no limit.

Furthermore, in addition to the auditory perceptible signal, a visually perceptible signal can be added as a third type of information. For example, when two kinds of physiological signals are detected at the same time, or two kinds of physiological information can be obtained, In addition to being used to comprehensively judge the physiological state, the physiological state represented by the two signals and information can also be expressed separately; or, as mentioned above, it can also be used to represent the user's actual breathing situation, so that the user knows The difference between your own breathing and the breathing guide signal, etc. The visually perceptible signal can be provided by the above-mentioned illuminant, screen or device with display function, etc., without limitation.

Furthermore, the breathing guide signal can also be adjusted in real time according to changes in the physiological state of the user. For example, as mentioned above, when the user's relaxation level has increased and remained stable, the breathing guidance signal further reduces the breathing rate to further increase the relaxation level; or when the user's relaxation level has reached a desired level When the goal is reached, or when the breathing control has been stably consistent with the breathing guide, the breathing guide is stopped, so that the user can focus on self-consciousness control, only when the breath is found to be unstable again, or the degree of relaxation is reduced Only when the breathing guidance is started again; or the user is allowed to perform breathing training and physiological feedback alternately through the presence or absence of the breathing guidance. Therefore, it can be changed according to the actual use situation, or the user can choose a suitable method without limitation.

In addition, it should be noted that the perceivable signal generating source can be further implemented to be combined with the wearable physiological sensing device, for example, a display element of the wearable physiological sensing device, and/or Or a sound emitting element to provide a visually perceivable signal and/or an audibly perceivable signal, therefore, there is no limitation. Furthermore, especially when the perceivable signal generating source is implemented as a separate illuminant as shown in Figure 1, due to its physically independent characteristics, it can also be implemented as a switch by setting a switch, for example, a Keys, or dials, or, in particular, actuated by shaking, therefore, are not limited.

In addition, the physiological feedback (neurophysiological feedback) and/or breathing training carried out according to the device of the present invention are also suitable for integration into the game, so that, in addition to the change of the visual/auditory effect during execution, for example, changes with the physiological state Colors, object shapes, characters, sounds, etc., through games, more interactive content can be provided, for example, through a game software executed on mobile phones and/or computers, the interaction with users can be increased. The fun of the interaction increases the willingness to use it. For example, first, a point system can be used, for example, if the goal of neurophysiological feedback is relaxation, points can be used to represent the increase in relaxation in a segment, such as the proportion of alpha waves in the brain waves, Furthermore, since the physiological feedback has a cumulative effect, the scores obtained at different times and in different sections can be accumulated and calculated. In this way, users can easily know the results of their own efforts through the scores, which will help To cultivate a sense of accomplishment, and in this case, you can further set the threshold of different scores that can be achieved to increase the user's desire to challenge, and can cooperate with the concept of levels, when you reach a threshold, you can go to the next level , and open different functions, etc., to increase the fun of use and increase the willingness to use.

In addition, in addition to the concept of levels, rewards can also be provided. For example, when the accumulated scores reach a certain threshold, more optional character shapes can be added, for example, more types of clothes that can be changed, and halos appear. etc., or can give accessories, treasures, etc., or can improve the level of the player to give higher game capabilities, etc., the common ways of various online games are all suitable for the utility model.

Furthermore, due to the different nature of general games, the cumulative nature of physiological feedback is mainly built on the premise of continuous use, that is, when the interval between the executed physiological feedback procedures is too long, the cumulative effect will be lost. Accordingly, For example, the calculation principle of the score can be designed such that the accumulated score will gradually decrease as the time interval becomes longer. If the game is not played for too long, the score will be reset to zero, and the user must start from the beginning. For example, when the user does not use the physiological feedback program after 2 days, the cumulative score is reduced to 75%, after 3 days, the score is reduced to 50%, and so on, and finally when the user is not used after 5 days, the previous Accumulated points are reset to zero to motivate users to continue using.

Therefore, through the game, in addition to making the physiological feedback program more interesting, the user can also feel the physiological state changes caused by the physiological feedback in real time, so that the user can feel that there is a goal and increase the motivation to use it.

Here, it should be emphasized that the above-mentioned embodiments are only used as examples for illustration, not as limitations, and different embodiments can be combined or replaced with each other, and all still belong to the scope of the present utility model to be disclosed. .

In summary, according to the physiological feedback system of the present invention, the two programs of breathing regulation and physiological feedback are novelly combined. Breathing can affect the characteristics of the autonomic nervous system, and can also make the effect of physiological feedback more significant. The perceivable signal also allows the user to clearly and easily understand the information content during the physiological feedback process, and the physiological feedback program becomes more convenient. Therefore, this patent application can indeed bring improvements to the existing technology .
