Description

Wearable physiological detection device

Technical field

The present invention relates to a wearable physiological detecting device, and more particularly to a wearable physiological detecting device applied to a neurophysiological feedback section.

Background technique

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 exercise, etc. are currently supported by a large number of research results, and more and more people use this method.

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 this procedure, physiological activities that can be changed by the human body through consciousness, for example, thinking, emotion, and behavior, For example, brain waves, heart rate, respiration, muscle activity, or skin temperature are monitored by the instrument and information is quickly and accurately fed back to the subject. Since this information is related to the physiological changes that are desired, After obtaining the information, the tester can adjust the self-consciousness according to this and strengthen the physiological response required.

Neurophysiological feedback is a kind of physiological feedback by providing real-time brain activity information of the subject. One of the most common ways is to detect EEG (electroencephalography), and the user obtains relevant brain in real time. After the information of the activities of the Ministry, the effect of affecting the brain activities can be achieved through self-awareness adjustment.

In addition, there is a very important application of EEG, that is, as a brain computer interface (BCI), in which the EEG can be analyzed to obtain the user's intention, and then converted into operation. instruction. In recent years, such a brain-computer interface Coordination with neurophysiological feedback is also applied to games, for example, by allowing the user to focus on the game through the presentation of the game.

It can be seen that self-consciousness regulation is the most important way when it comes to improving the physical and mental health through the human body's own regulatory mechanism, or as a brain-computer interface. It is well known that focusing attention is on self-consciousness regulation. One of the most important means. Therefore, if the self-consciousness regulation can be assisted by increasing the concentration of attention during the neurophysiological feedback process, the goal of neurophysiological feedback can be achieved more efficiently.

In general, in the process of meditation, which 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 breathing. Therefore, focusing on respiratory rhythm is a known way to increase your concentration.

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 also be controlled by consciousness. Within a limited range, the human body Self-control of breathing rate and depth, etc., so studies have shown that the balance of sympathetic and parasympathetic nerves can be affected by controlling the way of breathing. In general, exhalation increases parasympathetic activity, slows heartbeat, and sucks. During the gas phase, it increases sympathetic activity and accelerates the heartbeat.

Therefore, when it is necessary to concentrate on the respiratory rhythm, in addition to achieving the concentration and stability of the breath due to returning to the rhythm of exhalation and exhalation, it also affects the autonomic nervous system. At this time, as long as the effect of breathing on the autonomic nervous system is consistent with the goal of performing neurophysiological feedback, for example, relaxing the body and mind, it is natural to increase the effect of the neurophysiological feedback by increasing the control of the breathing. The building achieves complementary effects.

Therefore, there is indeed a need to develop a novel system that can be When the neurophysiological feedback is controlled by consciousness, the basis for further adjustment of the breathing is provided, so that the effect of the breathing on improving the physical and mental health can be simultaneously exhibited, thereby complementing the effect that the neurophysiological feedback can achieve.

detailed description

The purpose of the device of the present invention is to integrate a program that affects brain activity through self-awareness adjustment and respiratory regulation into the same neurophysiological feedback segment, and form a neurophysiological feedback loop by interacting with the user. The way to strengthen the impact on brain activities, so that the results achieved by the program can be further improved.

Under this principle, the wearable physiological detecting device according to the present invention is provided with at least two EEG electrodes and a heart rate sensing unit, wherein the EEG electrode is used to obtain an EEG signal to know the user's The brain activity situation, and the heart rate sensing unit is used to obtain a heart rate sequence as a basis for providing and/or adjusting the respiratory guidance signal.

In general, at least two electrodes are required to obtain an EEG signal, one of which is effective The active electrode and the other are used as reference electrodes. It is also common to add a ground to suppress common mode noise, such as 60 Hz and 50 Hz noise. Therefore, in the following description, two electroencephalogram electrodes are mainly described.

In addition, because 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 heartbeat is slowed down during breathing, so the user's breathing behavior can be obtained by measuring the heart rate. In general, when the breathing and the heartbeat are in synchronization with each other, the change of the breathing behavior pattern can be known by analyzing the heart rate sequence, and in the present invention, the sensing unit for obtaining the heart rate sequence can be It is implemented as a light sensor or an electrocardiographic electrode, wherein the photosensor refers to a sensor having a light-emitting element and a light-receiving element and acquiring an optical signal by using a PPG (photoplethysmography) principle, which can detect a continuous change of the pulse. The heart rate sequence is known, for example, by a transmissive or reflective measurement method, and the electrocardiogram electrode can obtain an electrocardiogram to obtain a heart rate sequence.

Moreover, when the heart rate sequence is obtained, HRV (Heart Rate Variability) analysis can also be performed, and HRV analysis is one of the common means for learning the activity of the autonomic nervous system, for example, frequency domain analysis (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 and parasympathetic nerves At the same time, the low frequency power (LF) of the control results, and the LF/HF (low high frequency power ratio) which can balance the activity of the sympathetic/parasympathetic nerves, and the frequency can also be observed after the frequency analysis. The state of distribution is known to the harmony of the operation of the autonomic nervous system; alternatively, Time Domain can be used to obtain an SDNN that can be used as an indicator of overall heart rate variability, 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-MSSD, which can be used to estimate high-frequency variation in heart rate variability, NN50, and PNN50, etc. Therefore, neurophysiological responses can also be learned by analyzing heart rate sequences. The effects of feeding and/or respiratory regulation on the autonomic nervous system.

Therefore, under the concept of the present invention, brain activity information, autonomic nerve activity information, and respiratory behavior patterns complement each other, which can provide a more comprehensive and effective neurophysiological feedback mode for the user, and maximize the effect of self-consciousness regulation. . Moreover, in the case of using a light sensor, information about the blood oxygen concentration can be obtained, which helps to further understand the physiological condition of the user.

In actual implementation, as shown in FIG. 1, the wearable physiological detecting device 10 according to the present invention is configured by disposing a device on a user's head mainly through a wearing structure 14, and adopting a configuration of an electroencephalogram electrode and a photosensor. The device 10 has a host 12 carried by the head-mounted structure 14, and a physiological signal capturing circuit is disposed to obtain a physiological signal through the brain electrical electrode and the light sensor. Therefore, the physiological signal capturing circuit 10 may include, but is not limited to, some common electronic components used to achieve measurements, such as processors, at least one A/D converter, filters, amplifiers, etc., as these are common to those skilled in the art. Therefore, I will not repeat them.

In addition, two EEG electrodes are disposed on the user's head through the head-mounted structure, for example, on the inner side surface of the head-mounted structure to contact the sampling points on the head. For example, common sampling points include Fp1. , Fp2, O1, O2, etc., or any position defined by the 10-20 system, and then obtain an EEG signal, where 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 can be performed by increasing the number of effective electrodes, and thus, there is no limitation.

In the present invention, the electroencephalogram electrode is implemented as a dry electrode, for example, stainless steel, conductive fiber, conductive rubber, conductive foam, conductive gel, and the like, or a metal or conductive substance, so that the user can directly contact the scalp. The way of the skin to obtain the EEG signal, there is no problem faced by the traditional wet electrode, for example, the need to use the conductive paste and the electrode needs to be attached, etc., so that not only can increase the ease of use, but also enhance the user's willingness to use. In addition, the headgear structure can be implemented in various forms, and can be a headband as shown in the figure. Band), or other forms, for example, headgear commonly used in general EEG measurement, or glasses, etc., as long as it can be placed on the head and ensure the location of the EEG electrode and the skin The inter-contact can be, for example, the usual head-wearing structure is designed to surround the form around the skullcap to facilitate placement of the electrodes at the sampling points corresponding to the cerebral cortex, and thus, there are various possibilities and no limitations.

In addition, the light sensor can also be disposed at any position on the user's head through the head-mounted structure, for example, contacting the forehead to obtain a continuous pulse change; or, alternatively, as shown in FIG. 2, the light sensor It can also be extended beyond the wearing structure by a connecting wire to be placed on one ear, and the pulse continuous change can be easily obtained, and the reflection type or the actual measurement position and the implementation consideration can be selected. There is no limit to the way of penetrating measurement.

Here, further, when the light sensor is implemented to be disposed on the ear, it may also be disposed through an ear-worn structure, for example, through an ear clip (such as the ear clip 16 in FIG. 2), an ear hook, or an earplug. Form, in the area near the ear or ear, for example, the earlobe, the inner surface of the auricle, such as the ear cavity and the area near the external ear canal, etc., the ear wheel, the back of the auricle, the outer ear canal, or the vicinity of the ear and the head shell There are no restrictions on the area, etc. Moreover, by using an appropriate ear-wearing structure, the fixing effect of the sensor setting can also be increased, thereby effectively improving the stability of the obtained signal.

In addition, preferably, one of the EEG electrodes can also be implemented in the ear-wearing structure. In particular, in the field of EEG detection, the ear is separated from the head due to its structure and position, and is not easily affected by brain activity. The effect has always been regarded as one of the best positions for setting the reference electrode. Therefore, the reference electrode is combined with the ear-wearing structure to contact the ear or the vicinity of the ear, which is not only beneficial for obtaining good EEG signals, but also Without increasing the complexity of the overall configuration, it is quite advantageous.

For example, the ear clip structure shown in FIG. 3A is an ear-wear structure that is generally easy to install and easily achieves contact stability. As shown in the figure, the light sensor is implemented to be mounted in the ear clip. A light emitting element 141 and a light receiving element 142 on the opposite side of the portion are used to obtain a continuous pulse change by using a penetrating measurement method, and the brain electrode 143 is also disposed inside the ear clip to be in contact with the clip. The position of the ear skin in the position, so that the mechanical force of the clip itself, whether the light sensor or the brain electric electrode can be stably placed on the ear, is not easy to move, which is quite helpful for obtaining good quality. The signal is more conducive to obtaining accurate analysis results.

Wherein, when the photosensor and the electroencephalogram electrode are simultaneously disposed in the ear clip structure, there are many options for setting the positions of the two. For example, as shown in FIG. 3A, the electroencephalogram electrode can be implemented as a surround light emission. The element/light receiving element is disposed, or, as shown in FIG. 3B, the electroencephalogram electrode and the light emitting element/light receiving element are also separately disposed, and electrodes can be disposed on both sides of the ear clip for reference. The electrode and the ground electrode may be configured to provide an electroencephalic electrode as a reference electrode only on one side of the clip, and therefore, without limitation, or further, as shown in FIG. 3C, the light-emitting element 141 and the light-receiving element 142 It can be set on the same side to measure the heart rate by reflection, and the electroencephalogram electrode 143 is set on the other side.

Here, it should be noted that the ear clip can be implemented at any position sandwiched on the ear, that is, any position protruding from the auricle of the head shell, for example, an ear lobe, a rat wheel, etc., and the mechanical structure thereof can also be There is no limit to the actual clamping position.

Therefore, the physiological signal capturing circuit included in the wearable physiological detecting device can set the wearing structure on the head (and the ear wearing structure setting) during the execution of a neurophysiological feedback section by the user. On the ear, and simply complete the installation of the electrode and the light sensor, after the EEG signal obtained by the EEG electrode is calculated by a preset calculation formula, information about the brain activity of the relevant user can be obtained. As a basis for providing users with self-awareness regulation, and the heart rate sequence obtained by the light sensor can also obtain information about the breathing behavior pattern of the user after calculation through the calculation formula, as providing and/or adjusting the respiratory guidance signal. Foundation.

Furthermore, please refer to FIG. 4A, which shows an implementation of the wearable physiological detecting device according to the present invention using an electroencephalogram electrode to obtain an electroencephalogram signal, and using a cardiac electric electrode to obtain a heart rate sequence. In this embodiment, similar to the embodiment of FIG. 1, the electroencephalogram electrode contacts the sampling point of the head through the head-worn structure, and additionally adds at least two electrocardiographic electrodes, as shown in the figure, one of the electrocardiograms The electrode is disposed on the finger through the finger wearing structure 181, and the other electrocardiographic electrode contacts the skin of the head through the wearing structure to achieve a circuit for measuring the ECG signal, so that the user can The ECG signal is obtained easily and without force, and the heart rate sequence is obtained. Alternatively, alternatively, the electrocardiographic electrode that contacts the skin of the finger through the finger-wearing structure may also be implemented to contact the skin of other parts of the body, for example, as shown in FIG. 4B, contacting the skin in the vicinity of the wrist through the wrist-worn structure 182. Or contacting the skin of any part of the forearm or upper arm through the arm-worn structure 183, as shown in FIG. 4C, or contacting the skin near the neck, shoulder or back, as shown in FIG. 4D, contacting the neck with a neck-worn structure 184 The situation near the junction of the shoulders, or the skin contacting other parts of the trunk, etc., is not limited as long as it can form an electrocardiographic signal capture circuit together with the electrocardiographic electrodes of the head.

Wherein, when the electrocardiographic electrode is disposed near the neck, the shoulder or the back, the wearing structure used to maintain the contact between the electrocardiographic electrode and the skin is preferably implemented to have elasticity, for example, using an elastic metal or a conductive material. Made of rubber, conductive fiber, conductive foam, etc., it can match the curve of the neck and shoulder as much as possible, and help to obtain a stable ECG signal.

In still another preferred embodiment, the electrocardiographic electrode disposed in the head-mounted structure can be further implemented to be shared with the electroencephalogram electrode, that is, one of the electrodes that contact the skin of the head through the head-wearing structure simultaneously serves as an electroencephalogram The electrode and the electrocardiographic electrode can, in addition to the reduction in manufacturing cost and complexity, increase the convenience of use by reducing the position to be contacted.

Furthermore, as shown in FIG. 5A, both ECG electrodes may be disposed on the head-mounted structure. In this case, it may be implemented that one electrode is located through the head-mounted structure. The position of contacting the skin, and the other electrode 18 is located at a position where the wearing structure is exposed on the head and not in contact with the skin, so that the user can measure the electrocardiogram by means of the upper limb skin contacting the electrocardiographic electrode. The detection circuit of the signal, in this way, the acquisition of the ECG signal will depend on the needs of the user. When there is a need to measure, it is only convenient to start the measurement by contacting the exposed electrode with the upper limb.

In addition, the electrocardiographic electrode may also be disposed on the ear-wearing structure, as shown in FIG. 5B. For example, an electrocardiographic electrode may be separately disposed in the ear-wearing structure, and the exposed portion of the ear-wearing structure may be disposed on the other core. The electric electrode 18, in this way, the ear-wearing structure can also be implemented in a detachable form, and can be connected and used when the user needs it; or, as described above, when one of the electroencephalogram electrodes is worn through the ear When the structure is disposed on the ear, the electrocardiographic electrode is simultaneously disposed therein, or the electroencephalogram electrode is shared as an electrocardiographic electrode; or alternatively, an electrocardiographic electrode is contacted to the head skin through the wearing structure. The other electrocardiographic electrode is disposed on the exposed surface of the ear-worn structure for measurement by the user, so that various combinations are possible without limitation. Moreover, the ear-wearing structure is also not limited to what form, for example, ear clips, earplugs or ear hooks, etc., are common forms of implementation.

Furthermore, it may be further implemented to have both a photosensor and an electrocardiographic electrode. For example, as shown in FIG. 5B, the photosensor is simultaneously disposed in the earwear structure and the electroencephalogram electrode and the electrocardiogram electrode are provided. a shared electrode, in combination with another EEG electrode on the headgear structure, and another electrocardiographic electrode 18 positioned in the exposed portion of the earwear structure, or alternatively, a photosensor and an electrocardiographic electrode disposed in the earwear structure While both EEG electrodes are in contact with the head skin through the head-worn structure, various embodiments are possible.

The advantage of such a configuration is that the optical sensor obtains the heart rate sequence and the ECG electrode to obtain the electrocardiogram, which can achieve the effect of conveniently and correctly determining the symptoms of arrhythmia. Since the light sensor can continuously obtain the pulse change during the wearing process, it is possible to first screen whether there is a possibility of arrhythmia by analyzing the continuous pulse change, that is, the pulse phase can be known by analyzing the continuous pulse. Corresponding heart beats, and then screen out whether there is a possibility of arrhythmia, for example, Premature Beats, heart Various symptoms such as AF (Atrial Fibrillation), Tachycardia, Bradycardia, Pause, etc. However, since the basis of the analysis is continuous pulse, it is impossible to distinguish Symptoms of judging the waveform of the electrocardiogram, for example, early-onset contractions are divided into premature atrial contractions (PAC) occurring in the atria, and premature ventricular contractions occurring in the ventricle. PVC). When distinguishing between the two, it is usually possible to judge whether the contraction is from the atria or the ventricle by observing whether the shape of the P wave and/or the QRS wave is abnormal. In addition, since the pulse is transmitted by the heart in the blood vessel through the blood The measured result, so its accuracy can not be compared with the ECG.

Therefore, with such a design, when the possibility of arrhythmia is found by continuously analyzing the pulse, it is only necessary to notify the user in real time by the notification signal that the possibility of arrhythmia is found, and the user can naturally touch by hand. Exposing the ECG electrode, or wearing the ECG electrode on the finger, wearing it on the wrist, or touching other parts of the body, immediately measure the ECG signal and obtain an ECG that may have an arrhythmia in real time. It is quite convenient to accurately determine whether arrhythmia really occurs or even to determine the type of arrhythmia.

Here, it should be noted that although the figure is shown in the form of a head-mounted structure carrying host, it can also be implemented in other forms. For example, the physiological signal capturing circuit can be directly disposed in the head-mounted structure and omitted. The host, for example, the head-mounted structure can be implemented as an internal accommodating space or as a flexible circuit board capable of carrying a circuit, and thus can be changed according to actual conditions without limitation.

In addition, in particular, the spectacles structure can also be used to simultaneously achieve the sampling position around the cap bone and on or near the ear, that is, all possible embodiments in the foregoing FIGS. 1-2 and 4-5 can be used. The belt is replaced by a spectacles structure, because the position where the spectacles frame naturally contacts when the glasses are worn includes, but is not limited to, the nose pads contact the bridge of the nose, the roots, and/or the eyes, and the front ends of the temples are in contact. Near the temple, the back of the temple will contact the V-shaped recess between the auricle and the skull, and the temples fall behind the auricle. Some of them will touch the skin behind the auricle, and these positions are the positions where the light sensor and/or the electrode can be placed. Moreover, in this form, it is almost the same as the general glasses, and the detection device can be more integrated into daily life. User's willingness to use.

The spectacles structure described herein refers to a wearing structure that is placed on the head through the auricle and the nose as a support point and that comes into contact with the skin of the head and/or the ear, and thus is not limited to a general spectacles structure. Also included is a deformation thereof, for example, a structure having a clamping force on both sides of the skull, or a contact point extending further to the back of the brain as a occipital region, or alternatively, an asymmetrical form of the temples on both sides. For example, one side of the temple has a curved portion behind the auricle, and the other side has a curved portion that is only placed over the auricle, and may or may not have a lens. Therefore, there are various possibilities and no limitation.

In terms of material selection, in addition to the hard material of ordinary glasses, it can also be implemented as an elastic material, which not only increases the stability of the electrode contact, but also provides the use comfort. For example, the memory metal and the flexible plastic can be utilized. The material is formed into a frame, and/or elastic rubber, silica gel, etc. are disposed at the electrode contact position to make the contact more stable and unlimited.

There are also various possibilities for the combination of the light sensor, the brain electrical electrode, and/or the electrocardiographic electrode and the eyeglass structure.

Here, it should be noted that, as mentioned above, only one of the at least two electrocardiographic electrodes contacts the head and/or the ear through the spectacle structure, and the other electrode is disposed on the other end. When an eyeglass structure is worn on an exposed surface, the user's hand is touched to obtain an electrocardiographic signal, as shown in FIG. 6A, or other position placed on the user by another wearing device, for example, Neck, shoulder, back, arm, wrist, finger, chest, etc. Therefore, the manner in which the photosensor/electrode described next is combined with the spectacles structure is for at least two EEG electrodes, or at least one photosensor, Or at least one ECG electrode.

For example, the light sensor/electrode and the required circuit (eg, processor, battery, wireless transmission module, etc.) can be directly embedded in the eyeglass structure, for example, in the temple, the lens frame, to wear the eyeglass structure. The action is to achieve the electrode, the sensor is in contact with the head and/or the ear, or the configuration of the photosensor/electrode or circuit can be achieved by an additional structure. For example, as shown in FIG. 6B, the additional structure 60 can be implemented to extend from One-sided temples such that, for example, two EEG electrodes, one ECG electrode, and/or a light sensor contact a contact point near a single auricle; alternatively, the additional structure can also be implemented as a bilateral eyeglass Extending out and each having at least one electrode to contact at least two contact points near the auricles of the two sides to obtain an EEG signal, and the ECG electrode and/or the photosensor are not limited to which side, in this case The electrical connection between the two additional structures can be achieved by the spectacles structure, and the required circuit can be partially or completely disposed in the spectacles structure or the additional structure as needed. Step, the additional structure may be embodied in the form of a removable, to enable a user can then selectively bind with additional structures when necessary to detect the structure of glasses. Therefore, there are various possibilities and no restrictions.

Next, the wearable physiological detecting device according to the present invention can also be implemented to be placed on one of the ears of the user through an ear-wearing structure. For example, FIGS. 7A-7B show an exemplary embodiment of an ear-worn physiological detection device 20 with an electroencephalic electrode with a light sensor. In the embodiment of FIG. 7A, the ear-worn structure is implemented as an earloop structure 21 with an ear. a clip structure 22, wherein the ear clip structure 22 is sandwiched on the earlobe as a position for arranging the photosensor and the reference electroencephalogram electrode, and the effective electroencephalogram electrode is located at the earloop structure 21 or the earwear structure Other parts, such as the housing 23, may be in other locations in contact with the skin in the vicinity of the ear or ear, in order to obtain an EEG signal, i.e., the location of the activity of the cerebral cortex can be detected; in addition, in the embodiment of Figure 7B The earwear structure is implemented as an earhook structure 21 and an upper earplug structure 24, wherein the light sensor and the reference brain electrical electrode are disposed on the earplug structure to contact the inner ear canal, the outer ear canal, and/or the ear canal. The cavity is positioned to obtain a signal, and the effective EEG electrode is implemented to be located in the earloop structure 21, or other portion of the earwear structure, for example, the housing 25, which can be attached to the skin near the ear or the ear. EEG acquired position, therefore, there are various possible forms of implementation. Moreover, it can also be implemented as a single earhook structure, that is, only an earhook, an ear clip, or an earplug structure, to complete the brain electrical electrode and the light transmission Sensor settings are not limited.

In addition, as shown in FIG. 8A, the ear-wearing form physiological detecting device 30 may be implemented as an electroencephalogram electrode and an electrocardiographic electrode. In this embodiment, an electrocardiographic electrode 31 is exposed to be exposed to the upper limb skin. Contacting to achieve an ECG signal detection circuit, and another ECG electrode is implemented to contact the skin near the ear or ear through the ear-wearing structure, and it can be implemented to be shared with one of the EEG electrodes, or independently set, Without limitation, the two EEG electrodes are implemented to contact the ear or the vicinity of the ear through the earloop structure 32 and/or the housing 33 to obtain two positions of the EEG signal, that is, the cerebral cortex activity can be detected. Or the ear clip structure can be added, for example, to the earlobe or the ear wheel, and a shared reference electroencephalic electrode and an electrocardiographic electrode are disposed therein, and the exposed electrocardiographic electrode 31 is attached, and the ear strap is attached. An effective EEG electrode that is configured to be placed at the sampling position.

Furthermore, the electrocardiographic electrode that requires skin contact of the upper limb can also be implemented on the finger by the finger-wearing structure, as shown in FIG. 8B, or on the wrist, or on the arm, neck, shoulder or back. The nearby position, as shown in Fig. 7C, shows the contact of the neck, shoulder or back skin through the neck-wearing structure to provide further convenience, and of course, can also be implemented to contact other body parts, for example, the torso is also selectable. s position.

Further, similarly, the ear-worn physiological detecting device 40 may be further provided with an electroencephalogram electrode, a photosensor, and an electrocardiographic electrode. As shown in FIG. 9, the photosensor may be fixed to the earlobe by the ear clip 42. Above, one ECG electrode 41 is embodied in a form that is exposed to skin contact of the upper limb, and the other ECG electrode is implemented to be located inside the ear clip 42 or to contact the ear through the earloop structure 43 and/or the housing 44 or Other locations in the vicinity of the ear, in addition, as described above, the EEG electrodes may also have different implementation possibilities. For example, the reference electrode may also be disposed in the ear clip 42 or further implemented to be shared with the electrocardiographic electrode in the ear clip; The contact between the two EEG electrodes and the skin is achieved either by the ear wearing structure and/or the housing, and therefore, there is no limitation.

Here, the special position of the electrode on the auricle should be specified. Please refer to Figure 10. The structure of the auricle (also known as pinna), in which the concha floor is located around the upper concha and the inferior concha on the inner side of the auricle (also That is, parallel to the plane of the skull) is connected upwards to a vertical area of the antihelix and the antitragus, called the concha wall, the natural physiological structure of which provides just perpendicular to the ear. a continuous plane at the bottom of the nail, in addition to the underside of the ear wall, the intertragic notch between the tragus and the tragus, and the adjacent tragus, also providing vertical The contact area at the bottom of the ear.

During the experiment, it was found that the continuous vertical area consisting of the ear wall, the tragus between the tragus, and the tragus, in addition to the obtained EEG signal strength, is sufficient for the relevant EEG signal analysis and provides information on brain activity. In addition, it is more advantageous that when this area is used as the electrode contact position, the force required to fix the electrode will be parallel to the force of the bottom of the ear, especially when implemented as an earplug, through the earplug and the inner surface of the auricle. The abutting force between the protrusions and the depressions naturally achieves stable contact between the electrodes and the vertical region at the same time.

In addition, the experiment also found that the intensity of the EEG signal obtained on the back of the auricle is also sufficient to carry out relevant EEG signal analysis and provide information on brain activity, and the contact position is suitable for ear hook form or glasses form. In general, the implementation of the ear-hook form usually has a component in front of and behind the auricle, and most of the effect is achieved by the interaction force between the two to fix the auricle. Therefore, when the electrode contacts the position When you choose the back of the auricle, it will meet the direction of the force of the interaction force, and naturally achieve a stable contact between the electrode and the skin on the back of the auricle.

When the form of glasses is used, the V-shaped depression between the auricle and the skull and/or the upper part of the skin on the back of the auricle is the position where the temples are in contact, and if the end of the temple is increased in curvature, The skin can be exposed to the lower part of the back of the auricle, and the stable contact of the electrodes can be naturally achieved.

Furthermore, please refer to Figure 11, which is the location of the cerebral cortex in the skull and the position of the auricle. The schematic diagram shows that the cerebral cortex is in the upper part of the skull, and the auricle is on both sides of the skull and protrudes beyond the skull. In general, it is separated by ear canal. The position of the upper auricle falls on the side of the cerebral cortex, while the inner part of the skull corresponding to the lower auricle has no cerebral cortex.

In the experimental results, it was also found that a good brain wave signal can be measured in the upper part of the auricle part, and the lower the EEG signal is, the lower the physiological structure of the head is, because the upper auricle is observed. The corresponding inside of the skull is the position of the cerebral cortex. Therefore, in this case, the brain wave can be measured in the upper part of the auricle through the transmission of the skull and ear cartilage, while the lower auricle is farther away from the cerebral cortex. In addition, the intensity of the EEG signal becomes weaker. Therefore, in the present invention, when the auricle (inside and back) is used as the position of the EEG signal sampling, in principle, With the ear canal as the boundary, the upper part of the auricle is regarded as the position where the EEG signal can be measured, and it is suitable for setting the effective electrode, and the lower auricle is regarded as the weak position of the EEG signal, which is suitable for setting the reference electrode.

Here, it should be noted that, when the ear wearing form is adopted, the physiological signal capturing circuit can be placed in the housing carried by the ear wearing structure or placed in the ear as shown in FIG. 6-8. The wearing structure and the housing, but not limited to the same, can also be directly received in the ear wearing structure without the housing, for example, in the ear hanging structure, the earplug structure, and/or the ear clip structure, therefore, There may be various possibilities, and the ear-wearing structure may be implemented as a single or a plurality of combinations, that is, the ear clip, the ear hook, or the earplug structure may be used alone, or a combination of the two or the combination of the three, the electrode and the The setting of the sensor can be changed according to the actual implementation, and there is no limit.

In a preferred embodiment, the electrodes and/or photosensors disposed in the vicinity of the ear and/or the ear are implemented to be attached to the ear by means of magnetic force. For example, magnetic attraction can be performed between the ears through the ear. The two components are achieved by placing the electrodes and/or sensors on either or both of the components, where the two components can be implemented to be magnetic, for example, by having a magnetic substance inside, or It is made of a magnetic substance or is made of a material that can be magnetically attracted. For example, one part may be made to have a magnetic force, and the other part may be magnetically attracted, or both parts may be Real The application of magnetic force can be implemented in various ways without limitation.

In still another preferred embodiment, a motion sensing component, such as an accelerometer, can be added to the device to know the movement of the user during the measurement, for example, the ear, the head, and/or the entire body. Movement, whereby the measured physiological signals, such as EEG signals, ECG signals and/or light sensing signals, can be corrected, for example, to correct for head or body movements The signal is unstable, which makes the content of the information provided to the user closer to the actual situation, which helps to improve the effect achieved by neurophysiological feedback.

In particular, the eyeglass structure and the earwear structure may be further combined for providing electrodes and/or light sensors, for example, an earplug or ear clip may be extended from the eyeglass structure, or the eyeglass structure has a port for electrical connection. An earplug or an ear clip, in this way, there are more implementation possibilities. For example, in the case of implementing an EEG electrode with a light sensor, the V-shaped recess and the pinna can be contacted through the electrode on the lens structure. The back surface, the temples, the bridge of the nose, and/or the area between the two eyes, and the electrodes on the earplug structure contact the ear wall, the tragus between the tragus, and/or the tragus to obtain the EEG signal, as for the light sensing Optionally, it is disposed on the eyeglass structure or the earwear structure; or, the brain electrical electrodes are disposed on the eyeglass structure, and the light sensor is disposed on the earwear structure; In the case of an electrocardiographic electrode, the exposed electrocardiographic electrode can be selectively disposed on the exposed surface of the spectacles structure or the ear-wearing structure, and then the electrocardiographic electrode disposed on the inner side of the spectacles structure can be used. The earphone/ear clip can be connected to the earphone/ear clip through the port to perform the extraction of the ECG signal. Further, the earwear structure can also be combined with the light sensor. Therefore, various embodiments can be implemented. no limit.

In addition, in addition to the electroencephalographic electrodes disposed on the ear-wearing structure, the head-mounted structure, and the spectacles structure, other electroencephalographic electrodes may be implemented, for example, extending from the ear-wearing structure, the head-wearing structure, and the spectacles structure. The electrodes disposed at other positions on the head, for example, are provided on the forehead to obtain an EEG signal in the frontal lobe area, and are disposed on the top of the head to obtain an EEG signal in the parietal region, and/or disposed in the occipital region of the occipital region. EEG signals, etc., and more particularly, when implemented in the form of glasses, the electrodes behind the skull can also extend backward through the temples. It can be achieved by the formula, so it can be changed according to the actual needs, there is no limit; in addition, when the electrode is provided with hair, such as the top of the head, the back of the head, etc., you can choose to use needle electrodes or other signals that can pass through the hair to obtain signals. Electrodes to increase ease of use.

In addition, other physiological signals can be additionally detected. For example, other physiological signals that are frequently monitored during physiological feedback procedures can be detected, for example, electrodermal activity (EDA, Electrodermal Activity), A slight limb temperature, etc., as a reference for providing feedback information, for example, additional information about the autonomic nervous activity may be provided in addition to the brain activity information, or the user may be provided for neurophysiological feedback after comprehensively considering the two. The information required, as long as it can correctly and effectively express the real-time physiological state, is an alternative.

Moreover, since the level of blood pressure has a certain relationship with the activity of the autonomic nerve, in general, the increase in sympathetic nerve activity causes an increase in pressure. Therefore, the pulse wave transit time can be obtained by the electrocardiographic electrode coupled with the glazing sensor (Pulse). Transit Time, PTT), then calculate the reference blood pressure value through a specific relationship between PTT and blood pressure value, so that the user can provide real-time blood pressure change trend during feedback or provide feedback segment before and after The blood pressure value, in order to let the user know whether the progress of the neurophysiological feedback affects the blood pressure, etc.; similarly, it is also possible to provide two light sensors, for example, in addition to the head/ear, and a finger The light sensor and the same information are obtained by calculating the time difference between the two pulse waves.

Next, in the present invention, the brain activity information and the respiratory guidance signal are provided to the user through a perceptible signal generation source. The communication between the sensible signal generating source and the wearable physiological detecting device, for example, by a general wireless communication method such as Bluetooth, WiFi, etc., the sensible signal generating source can receive the physiological detecting device from the head. The input is provided to the user in real time, thus achieving a neurophysiological feedback loop.

Here, the perceptible signal generating source is implemented to provide information about the user's related brain activity through a visually perceptible signal, or an auditory perceptible signal, and/or a tactilely perceivable signal. And a breathing guide signal, for example, a change in illuminating color, illuminating intensity, sound, voice, and/or vibration, etc., without limitation; and, the implementation of the sensible signal generating source can have many options, for example, for example The sensible signal generating source can be specially implemented as a separate illuminant, for example, a sphere, or an object of any shape, or implemented as a device having a display and/or vocal function, for example, a mobile phone, a watch, a lithograph A computer, a personal computer, or the like, or implemented as a device that can be displayed, audible, or vibrated on the body, for example, a single-sided earphone, a bilateral earphone, a pair of glasses, and the like.

Alternatively, the sensible signal generating source can also be implemented as a display unit, a sounding module, and/or a vibration module, etc. combined with the wearable physiological detecting device, for example, whether wearing a head-mounted structure or an ear wear. The sensible signal generating source can be implemented as a display component extending from the head-mounted structure/ear-wearing structure, a light source, and/or an earphone, etc., for example, can be implemented as a pair of glasses to carry EEG An electrode and a heart rate sensing unit, and displaying information through the lens, for example, guiding the light to the lens to exhibit a color change, or implementing the lens as having a display function, etc., and/or providing sound and voice through an earphone coupled to the vicinity of the temple Alternatively, or as an earphone, while carrying the EEG electrode and the heart rate sensing unit, the information is also provided by sound, or voice, and/or a display element or a light source is extended to the front to provide Visually perceptible signals, etc.; in addition, as long as the position in contact with the skin can be implemented to generate vibration, for example, the position where the temples contact the temples, or the headphones simultaneously Vibration function. Therefore, there is no limit.

Therefore, when the user performs a neurophysiological feedback program using the wearable physiological detecting device of the present invention, the wearable physiological detecting device is disposed on the head to pass the brain disposed on the inner side of the head wearing the same as in FIG. The electric electrode acquires the brain wave of the user, and the light sensor acquires the heart rate sequence, and then sets the sensible signal generating source that is implemented as the illuminant to a position that the eye in front of the body can naturally see, and the physiological detecting device on the head and The illuminator communicates, and as a result, the neurophysiological feedback procedure can begin.

Here, since the breathing practice and the neurophysiological feedback are combined, as described above, based on the progress of the breathing exercise, the user is required to provide a breathing guidance signal based on the neurophysiology. Feedback, information about the physiological activity of the user in response to performing neurophysiological feedback, 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 intensity and the illuminating color, wherein the illuminating intensity is used to express the breathing guide, and the illuminating color is used to express the related user brain activity. Information.

Since the purpose of the respiratory guidance signal is to allow the user to follow the breathing, it is necessary to be able to express the difference between inhalation and exhalation. Therefore, the illuminant represents the inspiratory and exhalation by continuously changing the intensity of the illuminating intensity. The continuous change, for example, is gradually increased as the illuminating intensity as a guide for gradual inhalation, and the gradual weakening of the illuminating intensity is used as a guide for gradual exhalation, so that the user can clearly and easily perform the vomiting.

When performing a neurophysiological feedback procedure targeting relaxation, one of the options is to observe the proportion of alpha waves in the 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 initiated, the illuminator provides respiratory guidance (through continuous changes in luminescence intensity) to guide the user to adjust their breathing, while the physiological detection device worn on the head also performs brain waves. The detection, and the acquired 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 according to 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 result of the analysis is compared with the reference value to obtain a relationship with the reference value. The relationship, for example, the increase or decrease of the ratio, and the illuminant can convey the change of the physiological state to the user in real time through the change of the illuminating color on the basis of 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 After changing the color, I know that my physical and mental state is nervous or relaxed, and I also carry out self-regulation while following the breathing guide, and make the illuminating color further toward the more relaxed goal.

Alternatively, the degree of relaxation or emotional state of the human body can also be understood by observing the energy balance and synchrony of brain activity in different brain regions. For example, when the body has a positive emotional response, the left prefrontal cortex The area is activated, and when a negative emotional response occurs, the right prefrontal cortex is activated. Therefore, the two parts of the cerebral cortex can be understood by detecting, for example, EEG signals at Fp1 and Fp2 positions. In addition, studies have also shown that when the human brain is in a state of alpha wave synchronization, a state of clear consciousness and relaxation can be achieved. Therefore, brain activity can be detected by detecting different brain parts, for example, Fp1 and Fp2 are related to the forehead. In the leaf area, C3 and C4 are related to the parietal lobe, O1 and O2 are related to the occipital lobe, and T3 and T4 are related to the temporal lobe, etc., and whether the brain is in sync. In this case, for example, by adjusting the position of the EEG electrode in the head-mounted structure, or by using two ear-wearing structures with EEG electrodes of the same device, they can be placed on the two ears, or The two ear-wearing physiological detection devices are placed on two ears, etc., and the brain activity of different brain parts can be obtained.

Further, when the goal of neurophysiological feedback is relaxation, the autonomic nervous activity obtained by analyzing the heart rate sequence can also serve as a basis for adjusting the illuminating color, for example, when parasympathetic activity increases, and/or parasympathetic activity. When the ratio of sympathetic activity increases, it means that the degree of relaxation of the body is increased. Therefore, the information can be combined with the information about the brain activity to evaluate the relaxation of the user's body, and then the change in the color of the illuminating feedback to the user can be adjusted.

Furthermore, since the RSA information can be obtained through the heart rate sequence, the heart rate, the respiration, and the synchronization between the EEG signals can be observed as a basis for feedback. According to research, exhalation and inspiration cause fluctuations in blood flow in the blood vessels, and this fluctuation also reaches the brain with blood flow, which in turn causes brain waves to approach the low-frequency segment of the breathing rate, for example, below 0.5 Hz. Fluctuation, therefore, besides knowing whether there is resonance between the two In addition to synchronicity, the breathing pattern can be known by observing the brain waves. In addition, since the sinus node and vascular system of the heart are regulated by the autonomic nervous system, the autonomic nervous system also passes through the pressure receptor system ( The baroreceptor system feeds heart rate and blood pressure changes back to the brain, which in turn affects the function and function of the brain, for example, affecting the cerebral cortex, and can be measured by EEG, plus consciously controlling breathing can affect heart rate due to affecting the autonomic nervous system. Change, therefore, there is a relationship between the three, so the good synchronicity between the three can represent the human body in a more relaxed state, according to which the correlation analysis results can also be provided as a user. Self-awareness adjusts information for neurophysiological feedback.

Further, the breathing pattern of the user may be known by observing the fluctuation of the blood flow. For example, the pulse change may be obtained by a photosensor provided at a position such as an ear or a forehead, and the change in blood flow rate may be known.

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 when the θ wave is dominant, the human body is in a state of relaxation and consciousness interruption. Therefore, by increasing the ratio of the β wave to the θ wave. To achieve the goal of increasing concentration, for example, one of the methods for treating patients with ADHD (Attention deficit hyperactivity disorder) is to observe the ratio of the θ wave/β wave by 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 luminescence intensity) to guide the user in adjusting their breathing while simultaneously wearing the head physiology The 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 the calculation of θ/θ+β and β/θ+等, etc., and then, according to the analysis result, a related information about the activity state of the user's brain is generated, and the illuminant is based on the information of the related user's brain activity, and the change of the illuminating color is transmitted to the user in real time. The change of brain function, for example, can be expressed in multiple colors. The closer to blue, the lower the concentration. The closer to red, the higher the concentration, the lighter the same color, the lighter the color. The lower the force, the darker the color, the higher the concentration, so the user It is very easy to know whether your concentration is improved by the change of color, and also carry out self-regulation while following the breathing guide, and make the illuminating color further tend to improve the target of concentration.

In addition to observing the ratio of theta wave to the beta wave, the slow cortical potential (SCP) is also a neurophysiological feedback that increases concentration. For example, when treating patients with ADHD, often observed brain activity, in which the SCP is negative. The negative shift is related to the more concentrated attention, and the positive shift of the SCP is related to the reduced attention.

Here, the brain activity represented by the illuminating color 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 can be used to indicate a change in a physiological signal. For example, the proportion of the alpha wave varies, and so on, there is no limit. Moreover, there is no limitation on the manner in which the illuminating color changes, and the emphasis is on allowing the user to understand his or her physiological state simply and clearly, and thereby driving the user to self-consciously control to achieve the target physiological state.

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

In the prior art, when performing neurophysiological feedback, the feedback mode for the user is usually implemented, for example, as a result of performing neurophysiological feedback to produce a moving object, such as a balloon floating in the air, The more relaxed the body, the higher the balloon floats; or the pattern that changes with the physiological state, for example, the flower that blooms because the body is more and more relaxed; or directly shows the change in the measured value; The guiding method is mostly implemented, for example, by the ups and downs of the waveform representing the inhalation and exhalation. Therefore, when combining the two, the user is easily disturbed by the visual display 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.

Therefore, in view of the above-mentioned possible problems, the present invention considers how to provide two kinds of information by 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 device. 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 problem that needs to pay attention to two focuses when combining two programs, and it helps to concentrate.

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

In addition to using a single illuminant to provide illuminating 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. The watch, the screen of the personal computer, etc. Further, the light source can also be implemented as part of the image, for example, the head of the human figure, or the position of the abdomen, etc., to help the user imagine the activity in the body during self-consciousness regulation. In addition, in addition to the form of the solid light source, the aperture is also a good implementation, for example, the aperture around the human head also helps the user to imagine. When the light source or the aperture on the screen as described above is implemented, the change in the intensity of the light emission can be further indicated by the change in the diameter of the light-emitting range to enhance the effect of guiding the inhalation and the exhalation. Therefore, it can be There are no restrictions on the actual implementation status.

In addition, an audible perceptible signal, such as sound or speech, may be additionally provided to provide an alternative when the user needs to close the eye for the feedback segment, for example, by the intensity of the volume representing the inhalation and Continuous changes in exhalation, and different types of sounds, such as bird sounds, sea waves, etc., or different tracks to represent different physiological states; or, voices can be used to indicate the user to inhale and exhale, but by sound The frequency indicates the physiological state. For example, the higher the frequency, the more nervous the tone is, the lower the frequency means the more relaxed, and so on, so there is no limit. Moreover, the auditory perceptible signal can be implemented as being provided by the perceptible signal generating source and/or by the wearable physiological detecting device, again without limitation.

As for the respiratory guidance signal, there are also many implementation possibilities. In general breathing exercises, 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; one is a preset breathing change with time. Change mode, for example, in a 15 minute 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 the other is A pattern of changes in breathing that changes dynamically with physiological conditions. Therefore, in the present invention, the respiratory guidance signal can provide an EEG signal and/or a heart rate sequence obtained by the wearable physiological detecting device, in addition to providing a preset breathing pattern that is fixed and changed with time. The respiratory guidance signal can be implemented to dynamically change with physiological conditions to provide a pattern of breathing changes that more effectively directs the user toward the target physiological state.

There are also various implementation options for the manner in which the physiological state of the user affects the respiratory guidance signal. For example, the actual respiratory behavior of the user can be known by analyzing the heart rate sequence, thereby learning the difference from the pilot signal, and adjusting the respiratory guidance signal, for example, when the user's own breathing rate is low. At the rate provided by the respiratory guidance signal, the breathing rate of the respiratory guidance signal can be lowered at this time to guide the user to further enhance the effect of physiological feedback.

Alternatively, HRV analysis of heart rate sequences can also be used to learn about autonomic nervous activity. Moreover, inferring the degree of relaxation of the user, when the degree of relaxation 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 may be implemented to stop the supply of the respiratory guidance signal when the user's degree of relaxation has reached the desired goal, or when the control of the breathing has steadily matched the respiratory guidance, and to use People can focus on self-awareness control, and only begin to breathe when they find that breathing is unstable or the degree of relaxation is reduced. Therefore, there is no limit.

Further, in particular, it may be implemented as a program that allows the user to alternately perform respiratory regulation and change the physiological state by self-consciousness regulation by the presence or absence of the supply of the respiratory guidance signal. According to research, when the procedure of affecting the physiological state is controlled by self-consciousness, if the breathing energy is in a smooth and stable state, the effect of the feedback can be additive, and therefore, the respiratory guidance signal is provided first by 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 simply concentrates on the self-awareness control program in the natural breathing mode that is used to it. The process will further enhance the feedback.

Moreover, since the breathing exercises have a delayed response to the effects of the autonomic nerves, by providing the guiding signals intermittently, in combination with the characteristics of the breathing practice and the self-awareness control program of the present invention, the respiratory guidance can be provided without During the period in which the effects of breathing exercises on the autonomic nerves are presented, it is convenient for the user to perform self-awareness control procedures, and the effects of breathing exercises are added.

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

In addition, it should be noted that the breathing guide signal supply mode may be implemented as: the respiratory guidance signal (which may be preset fixed, preset time varying, or dynamic change) is transmitted by the wearable physiological detecting device. After the sensible signal generating source, for example, a smart phone, a tablet computer, a smart watch, etc., the breathing signal is provided to the user by the sensible signal generating source for the user to perform breathing exercises; or Alternatively, the perceptible signal generating source may have a preset breathing change mode provided to the user, but further receives an input from the wearable physiological detecting device and adjusts the respiratory guiding signal, thereby no limit.

According to another aspect of the invention, it is also possible to provide brain activity information and a breathing guidance signal by means of an auditory perceptible signal. As shown in FIG. 2, the user can adjust his breathing and perform physiological feedback through the sound breathing guidance signal and brain activity information presented by the mobile phone.

Herein, the auditory perceptible signal for expressing the respiratory guidance signal may include, but is not limited to, for example, a time interval for generating the sound signal may be used 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. Let the user adjust the breathing as it changes; or the user can be informed by voice to inhale or exhale, for example, by "inhalation" and "exhalation" voice indications at the time of inhalation and exhalation. Introduce the user's breathing pattern.

When the auditory perceptible signal is simultaneously used to represent the information needed for physiological feedback, there are also many options. For example, the frequency or volume of the sound may be gradually higher or lower 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 distinguish from the respiratory guidance 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 snoring sound generated by the interval to guide the user to start inhaling or exhaling, and 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 learn to inhale while exhaling. Still too nervous, you need to find a way to relax, so even with a single voice signal, you can clearly let the user know both 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 by a bird's voice. The sound of the waves is more relaxed, and it is also a way to express it clearly.

Wherein, the auditory sensible signal can also be generated by a sound emitting module combined with the wearable physiological detecting device, for example, can be implemented as a headphone combined with a head or ear wearing physiological detecting device, in this case, The user only needs to wear a single device on the body to obtain physiological signals, as well as feedback/breathing guidance, which is highly mobile and convenient, and if implemented in glasses or earwear, More aesthetically pleasing, suitable for daily use, especially suitable for closed-eye feedback section during commuting, which is quite convenient. In particular, the vocal module and earphone used can be used in addition to the common air conduction form. In the form of bone conduction, for example, a bone-transmitting earphone can be used, and a bone conduction horn can be directly disposed at a position where the temple is in contact with the skull, or a bone conduction earphone can be extended from the temple foot without limitation.

Wherein, when implemented in the form of glasses, the functions of the earphone and/or the microphone may be provided by providing a sounding element and/or a sounding element (for example, a microphone) on the eyeglass structure, or may be extended by the eyeglasses. In the manner of the earphone, in particular, the sounding element and the earphone used may be in the form of bone conduction, in addition to the generally common air conduction form, for example, directly at the position where the temple is in contact with the skull. Bone conduction headphones, or bone conduction headphones extending from the temples, there is no limit.

Furthermore, the concept according to another aspect of the present invention may also be implemented to provide brain activity and respiratory guidance signals through tactile sensible signals, for example, may be implemented to use a vibration signal to alert the user to correct exhalation and/or Or the inspiratory start time point, or the vibration guidance is generated only when the user's breathing mode is found to be deviated from the preset target guiding signal; in addition, the different physiological states can be expressed by the strength of the vibration. For example, when the goal of physiological feedback is to relax, the stronger the vibration, the higher the degree of tension, and as it relaxes, the intensity of the vibration becomes weaker.

Here, it is advantageous that when the hearing and/or tactile guidance is adopted, the user can put both eyes on the feedback section, which is more helpful for body relaxation and breathing adjustment.

Further, it may be further implemented to simultaneously provide an auditory perceptible signal and a tactile perceptible signal, for example, using a vibration signal to remind a time point of exhalation and/or inhalation, and using a voice to inform the user of a change in physiological state, or The sound guiding signal is provided by sound, and the user is reminded of the current physiological state by vibration. There is no limitation. The preferred embodiment is a vibration-equipped earphone, which can not only close the eye, but also affect other surrounding areas. It is quite convenient to carry out the feedback section in the case of a person.

Furthermore, when the implementation according to the present invention is to communicate with a portable electronic device, for example, a wired or wireless device such as a headphone jack or Bluetooth is used to communicate with an electronic device such as a smart phone, a tablet computer, or a smart watch. In the case of a sound emitting element (air conduction or bone conduction type) and a sound pickup element, the ear-worn or eyeglass type device according to the present invention can be used as a hands-free earpiece for talking, and further, by setting vibration The module, the sound emitting element (air conduction or bone conduction type), the display element, and the light emitting element, etc., the earwear or eyeglass device according to the present invention may further implement an information providing interface as the portable electronic device, for example It is used to provide call reminders, message notifications, etc., and is more integrated into the daily life of the user. As for the provision of information, there are various restrictions such as sound, vibration, illumination, and lens display.

Next, according to a further aspect of the present invention, since the device according to the present invention adopts a wearable form, it is also suitable for use as a brain-computer interface, and in the case where the detected physiological signal mainly includes an electroencephalogram signal and a heart rate sequence. In the following, there are several possible ways to generate instructions. For example, but not limited to, the proportion of alpha waves in brain waves varies greatly with the movements of closed eyes and blinks. In other words, when the eye is closed, the ratio of the alpha wave is greatly increased. Therefore, it can be used as a basis for generating an instruction. In addition, when the position of the electroencephalogram electrode is placed near the eye, for example, the bridge of the nose, the root of the mountain, and the eyes of both eyes In the case of inter-area, temples, etc., eye movements can also be detected, and eye movement signals (EOG) can be obtained. Therefore, instructions can be issued by, for example, blinking, eye-turning, etc.; It is also a physiological activity that the human body can control. As mentioned above, breathing not only affects the heart rate (ie, the so-called RSA), but also causes fluctuations in the brain wave in the low frequency segment. Therefore, under the framework of the present invention, whether the brain wave signal is detected or the heart rate sequence is detected, the user's breathing behavior pattern can be changed thereby, and thus, as a basis for generating instructions, for example, the user can specifically It is possible to increase the heartbeat variability rate by deepening the breathing during the inhalation period, or to increase the RSA amplitude, so as to be the basis for issuing the instruction. Therefore, there is no limitation.

In addition, when the motion sensing element is matched, for example, the accelerometer, there may be more command modes, for example, when the various physiological phenomena described above can be combined with the up and down nodding, the left and right rotation of the head, and the like. More kinds of instructions can be combined to make the application wider, for example, it can be applied to virtual reality games, smart glasses, etc., which are very suitable.

Furthermore, the neurophysiological feedback performed by the device according to the present invention is also suitable for integration into the game, so that, in addition to changes in visual/auditory effects, for example, colors, object types, people, which change with physiological state, Sounds, etc., through the way of the game, will provide more interactive content. For example, a game software executed on a mobile phone and/or a computer can increase the fun of interaction with the user, 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 alpha wave in the brain wave. The increased proportion, in addition, due to the cumulative effect of physiological feedback, the scores obtained at different times and in different sections can be cumulatively calculated, so that users can easily know the results of their efforts through the scores. It helps to cultivate a sense of accomplishment. In this case, the different score thresholds that can be achieved can be further set, the user's desire for challenge can be increased, and the concept of the level can be matched, and when a threshold is reached, it can be reached. The next level, and open different functions, etc., increase the use of fun, but also increase the 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 you can give accessories, treasures, etc., or to enhance the level of the player to give higher game ability, etc., and the common methods of various online games are suitable for 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, and accordingly, an example is given. In other words, the calculation principle of the score can be designed. For example, 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 procedure 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 encourage continued use by the user.

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

Furthermore, the device according to the invention is also applicable to the acquisition of sleep related information. As is well known to those skilled in the art, the electroencephalogram signal is the main basis for judging the sleep staging. Generally, the conventional measurement method is, for example, that a plurality of electrodes are arranged on the scalp and connected to one through a connecting line. Machine, but because it must be measured during sleep Quantity, such a method is not convenient for the user. Therefore, if the electrode configuration can be completed by the ear wearing form or the glasses form, it is naturally a less burdensome option, and in comparison, the unburdened detection method is The effects of sleep are also small, and results that are closer to the daily sleep situation will be obtained.

Furthermore, other electrophysiological signals can be measured by adding other electrodes or by sharing electrodes, for example, EOG, myoelectric signal (EMG), ECG (ECG). , electrodermal activity (EDA), etc., and these electrophysiological signals are items included in multiple sleep physiological examinations (PSG, Polysomnography). For example, EOG can provide rapid eye movement (REM, Rapid Eye) Movement), the EMG signal provides information on sleep onset and sleep offset, molars and REM. The ECG signal can be used to assist in observing the physiological state during sleep, for example, the state of the autonomic nerve, the heart. In the case of activity, etc., the skin electrical activity can provide information about the sleep stage. Further, if a light sensor is added, the blood oxygen concentration can be obtained to determine the occurrence of hypopnea and/or additional action. Sensing elements, such as accelerometers, can provide information on body movements and/or set up a microphone to detect snoring situations and the like. Therefore, it is quite convenient to obtain a considerable amount of information about sleep in a most unburdened situation by simply placing the sensor on the ear. In summary, the wearable physiological detecting device according to the present invention achieves the purpose of allowing the user to improve the concentration and enhance the feedback effect by providing the breathing guide in the neurophysiological feedback section, and the two complement each other and get twice the result with half the effort. In addition, the arrangement of the electrodes and/or the sensors is completed while the device is placed on the head and/or the ear by means of a head-mounted structure and/or an ear-worn structure, which not only increases the convenience of use but also greatly enhances Mobility. Furthermore, since the device according to the present invention is implemented in a wearable form, it is also suitable for use as a brain-computer interface, further enhancing the use value.
