Description

Wearable physiological detection device

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.

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 there are more and more people using methods.

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

Neurophysiological feedback is a kind of physiological feedback by providing information about the immediate brain activity of the subject. One of the most common ways is to detect EEG (electroencephalography), and the user gets the brain immediately. After the information of the activity, the effect of affecting the brain activity can be achieved through self-awareness adjustment.

In addition, EEG has a very important application, that is, as a brain computer interface (BCI), in which the user's intention can be analyzed by detecting the EEG, and then converted into operation. In recent years, such brain-computer interface and neurophysiological feedback have also been applied to games, for example, by allowing users to train their concentration through the presentation of games.

It can be seen from the above that when it comes to improving the physical and mental health through the body's own regulatory mechanisms, or as an application of the brain-computer interface, self-consciousness regulation is the most important way. As we all know, 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.

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

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 The breathing rate and depth can be controlled by themselves. Therefore, studies have shown that the balance of sympathetic nerves and parasympathetic nerves can be affected by controlling the breathing. In general, the parasympathetic nerve activity is increased during exhalation, and the heartbeat is slowed down. During inhalation, it increases sympathetic activity and accelerates the heartbeat.

Therefore, when you need to concentrate and focus on respiratory rhythm, in addition to being able to return to the rhythm of exhalation and exhalation to achieve concentration and stability, at the same time It has an effect on its own autonomic nervous system. At this time, as long as the influence 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 control of breathing. The effect of neurophysiological feedback is higher, achieving complementary effects.

Therefore, there is a real need to develop a novel system that provides a basis for further breathing adjustments when the user performs neurophysiological feedback through self-consciousness control so that the effects of breathing on improving physical and mental health can be simultaneously revealed. In addition, the synergistic effect of the neurophysiological feedback can be achieved.

A further object of the present invention is to provide a wearable physiological detecting device having a head-mounted structure disposed on a user's head and capable of setting an EEG electrode to a position at which an EEG measurement circuit can be achieved when worn. And setting the heart rate sensing unit at a position where the heart rate sequence can be obtained.

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 in the same neurophysiological feedback segment, and form a neurophysiological feedback loop by interacting with the user. The way to achieve the effect of the bonus on the brain activity, 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 brain. The activity is performed by the heart rate sensing unit 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 serves as an active electrode and the other as a reference electrode. It is also common to add a ground to suppress the common mode. Noise, for example, 60Hz and 50Hz 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 nervous system changes, the so-called Respiratory Sinus Arrhythmia (RSA), that is, the heartbeat is accelerated during inhalation. 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 in the respiratory behavior pattern can be known by analyzing the heart rate sequence, and in the present invention, the sensing unit for acquiring the heart rate sequence is used. It can be implemented as a photo sensor or an electrocardiographic electrode, wherein the photo sensor refers to a sensor having a light emitting element and a light receiving element and using PPG (photoplethysmography) principle to obtain an optical signal, which can be borrowed The heart rate sequence is obtained by detecting a continuous change of the pulse, for example, by a transmissive or reflective measurement method, and the electrocardiogram electrode can obtain an electrocardiogram, thereby obtaining 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 methods for learning the activity of the autonomic nervous system, for example, frequency domain analysis can be performed (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 Low frequency power (LF) of the simultaneous regulation of nerves, and LF/HF (low frequency work) that can balance the activity of sympathetic/parasympathetic nerves Rate ratio), etc. In addition, after performing the frequency analysis, the degree of harmony of the operation of the autonomous nerve can be known by observing the state of the frequency distribution; or, the time domain analysis (Time Domain) can be performed, and the whole can be obtained as a whole. The SDNN of the heart rate variability index can be used as an indicator of long-term overall heart rate variability, SDANN, RMSSD as an indicator of short-term overall heart rate variability, and R-MSSD, NN50, which can be used to estimate high-frequency variation in heart rate variability. And PNN50 and so on. Therefore, the effects of neurophysiological feedback and/or respiratory regulation on the autonomic nervous system can also be known by analyzing the heart rate sequence.

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 users, 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 mainly mounts the device on the user's head through a wearing structure 14 , and adopts an electroencephalogram electrode to cooperate with the light sensing. The device 10 has a host 12 carried by the wearing structure 14 and a physiological signal capturing circuit for obtaining a physiological signal through the brain electrical electrode and the light sensor. Therefore, the device 10 The physiological signal capture 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 knowledge in the art. They are all common content, so they will not be described again.

In addition, the second brain electric electrode is disposed on the user's head through the head-mounted structure, for example, on the inner side surface of the head structure to contact the sampling point on the head, for example, often See the sampling points including Fp1, Fp2, O1, O2, etc., or any position defined by the 10-20 system, and then obtain the EEG signal. Here, the position and number of EEG electrodes can be determined according to the nerves performed. The purpose of the physiological feedback is determined, for example, the number of effective electrodes can be increased to measure the multi-channel electroencephalogram, 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 conductive material, so that the user can directly contact the skin of the scalp. Obtaining EEG signals in a way that does not have the problems faced by conventional wet electrodes, for example, the need to use conductive paste and the need for electrodes to be attached, so that not only can the use convenience be increased, but also the user's willingness to use is enhanced. In addition, the headgear structure may be implemented in various forms, may be in the form of a head band as shown in the figure, or may be in other forms, for example, a headgear commonly used in general EEG measurement, Or in the form of glasses, etc., as long as it can be placed on the head and ensure the position of the electroencephalic electrode and the contact with the skin, for example, the usual wearing structure is designed to surround the form around the skullcap for easy The electrodes are placed at the sampling points corresponding to the cerebral cortex, so 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 wearing structure, for example, contacting the forehead to obtain a continuous pulse change; or, alternatively, as shown in FIG. 2, The light sensor can also extend out of the wearing structure through a connecting line to be disposed on one ear, and the pulse continuous change can be conveniently obtained, and can also be selected according to actual measurement position and implementation considerations. There are no restrictions on reflective or transmissive measurements.

Here, further, when the photo sensor is implemented to be placed on the ear, It can be set through an ear-worn structure, for example, through an ear clip (such as the ear clip 16 in Figure 2), an ear hook, or an earplug to fall in the area near the ear or ear, for example, the earlobe, auricle The inner surface, 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 area near the junction of the ear and the head shell, etc., are not limited, and through the use of appropriate ear-wearing structures, The fixing effect of the sensor setting can 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 or the vicinity of the ear in the ear-wearing structure, which is not only beneficial for obtaining a good EEG signal, but also Without increasing the complexity of the overall configuration, it is quite advantageous.

For example, the ear clip structure as 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 photo sensor is implemented as an opposite surface inside the ear clip. A light emitting element 141 and a light receiving element 142 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 contact the ear skin of the clamped position. The position, in this way, through the mechanical force of the clip itself, whether the light sensor or the brain electric electrode can be stably placed on the ear, it is not easy to move, which is quite helpful for obtaining good quality signals. It is more conducive to obtaining accurate analysis results.

Wherein, when the photo sensor 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 Provided around the light emitting element/light receiving element, or, as shown in FIG. 3B, the EEG electrode and the light emitting element/light receiving element may also be separately disposed, and may be in the ear clip Electrodes are provided on both sides as a reference electrode and a ground electrode. However, it is also possible to provide an electroencephalic electrode as a reference electrode only on one side of the clip, and therefore, there is no limitation, or further, as shown in FIG. 3C The light-emitting element 141 and the light-receiving element 142 may be disposed on the same side to measure the heart rate by reflection, and the electroencephalogram electrode 143 is disposed on the other side.

Here, it should be noted that the ear clip can be implemented at any position on the ear, that is, any position protruding from the auricle of the head shell, for example, ear lobe, ear wheel, etc., and the mechanical structure thereof can also be There are no restrictions depending on the actual position of the clamp.

Therefore, the physiological signal capturing circuit included in the wearable physiological detecting device can be disposed on the head during the execution of a neurophysiological feedback section by the user (and the ear wearing structure is disposed on the head) On the ear), the electrode and the light sensor are simply installed. After that, the EEG signal obtained through the EEG electrode is calculated by a preset calculation formula, and the relevant user's brain activity can be obtained. Information, as the basis for providing users with self-awareness control, and the heart rate sequence obtained by the light sensor can also be used to calculate and correlate the breathing behavior patterns of the user after calculation. The basis of the pilot signal.

Furthermore, please refer to FIG. 4A, which shows an implementation situation in which the wearable physiological detecting device according to the present invention uses an electroencephalogram electrode to obtain an electroencephalogram signal and a heart rate sequence using an electrocardiographic electrode. In this embodiment, similar to the embodiment of Fig. 1, the electroencephalogram electrode contacts the sampling point of the head through the head-wearing structure, and additionally adds at least two electrocardiographic electrodes, as shown in the figure, one of the electrocardiographic electrodes The finger is placed on the finger by the finger 181, and the other ECG electrode contacts the skin of the head through the head structure to achieve a loop for measuring the ECG signal, so that the user can Get the ECG signal easily and without stress, and then get the heart rate sequence Column. 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 area near the wrist through the wrist-worn structure 182. Skin, or contact the skin of any part of the forearm or upper arm through the arm-worn structure 183, as shown in Figure 4C, or in contact with the skin near the neck, shoulders or back, as shown in Figure 4D, through a neck-worn structure 184 The situation near the junction of the neck and the shoulder, or the skin contacting other parts of the trunk, etc., therefore, there is no limitation as long as the position of the electrocardiographic signal can be formed together with the electrocardiographic electrode of the head.

Wherein, when the electrocardiographic electrode is disposed near the neck, the shoulder or the back, the wearing structure for maintaining 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 a brain. The electric electrode and the electrocardiographic electrode, in addition to the reduction in manufacturing cost and complexity, can also increase the convenience of use by reducing the position that needs to be contacted.

In addition, as shown in FIG. 5A, two ECG electrodes may be disposed on the head-mounted structure. In this case, an electrode may be disposed to contact the skin through the head-wearing structure. The other electrode 18 is located at a position where the head structure is exposed on the head and is not in contact with the skin, so that the user can measure the ECG signal by contacting the skin of the upper limb with the electrocardiographic electrode. The detection circuit, in this way, the ECG signal acquisition will depend on the user's needs. When there is a need to measure, it is only convenient to start the measurement by touching the exposed electrode on 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 further disposed. The electric electrode 18, in this way, can also be implemented in a detachable form, and can be connected when the user needs it; or, as described above, when one of the brain electrical electrodes passes through the ear When the structure is worn 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 connected to the head through the wearing structure The skin, while 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 can be further implemented to have both a photo sensor and an electrocardiographic electrode. For example, the embodiment can be as shown in FIG. 5B, but the photo sensor is simultaneously disposed in the earwear structure and as an electroencephalogram. The common electrode of the electrode and the electrocardiographic electrode, together with another electroencephalic electrode on the head-mounted structure, and another electrocardiographic electrode 18 located in the exposed portion of the ear-wearing structure, or may be embodied as light disposed in the ear-worn structure The sensor and the electrocardiographic electrode, while the two EEG electrodes are in contact with the skin of the head by the head-worn structure, may be in various embodiments.

The advantage of such a configuration is that the photosensor 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 photosensor can continuously acquire the pulse change during the wearing process, it is possible to first screen whether there is arrhythmia possible event by analyzing the pulse continuous change, that is, it can be known by analyzing the continuous pulse. The heartbeat situation corresponding to the pulse, and then screen for possible arrhythmia possible events, such as premature beats, ventricular fibrillation (AF, Atrial Fibrillation), various symptoms such as Tachycardia, Bradycardia, and Pause. However, since the basis of the analysis is continuous pulse, it is impossible to distinguish between the need to observe the ECG waveform. Symptoms, for example, early-onset contractions are divided into premature atrial contractions (PAC) that occur in the atria, and premature ventricular contractions (PVC) that occur in the ventricle. When distinguishing between the two, it is usually possible to judge whether the contraction is from the atrium 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 a result measured after the heart beat is transmitted through the blood through the blood vessel, Its accuracy is also incomparable compared to the ECG.

Therefore, through such a design, when a heart rhythm irregularity event is found due to continuous changes in the analysis pulse, the user can immediately notify the user of the arrhythmia possible event through the notification signal, and the user can naturally touch the exposed heart through the hand. Electro-electrode, or the way the ECG electrode is worn on the finger, worn on the wrist, or in contact with other parts of the body, immediately measure the ECG signal, and instantly obtain an ECG that may have arrhythmia, so that it can be accurate. It is quite convenient to judge whether there is arrhythmia 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.

Furthermore, 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 above-mentioned Figures 1-2 and 4-5 can be used. Replace the headband with the eyeglass structure because the general glasses are worn The natural contact position of the eyeglass frame includes, but is not limited to, the nose pad contacts the bridge of the nose, the root of the mountain, and/or the area between the eyes. The front section of the temple contacts the vicinity of the temple, and the back of the temple contacts the auricle and the skull. The V-shaped recessed area and the portion of the temple that falls behind the auricle will contact the skin behind the auricle, and these positions are positions where the photo sensor and/or the electrode can be disposed, and, through such a form, almost Generally, the glasses are the same, which can make the detection device more integrated into daily life and increase the user's willingness to use.

The spectacles structure described herein refers to a wearing structure that is placed on the head by the auricle and the nose as a supporting 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 in the deformation, for example, may be a structure having a clamping force on both sides of the skull, or may further extend to the point of contact of the occipital region behind the brain, or may be implemented as 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 of the temple has no curved portion only above the auricle, and there is no 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, silicone rubber, 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 is in contact with the head and/or the ear by the spectacle structure, and the other electrode is set. Appeared on the exposed surface of the eyeglass structure for the user's hand to touch The electrocardiogram signal, as shown in FIG. 6A, or other position placed on the user through another wearing device, for example, a neck, a shoulder, a back, an arm, a wrist, a finger, a chest, etc., therefore, the next The manner in which the described photosensor/electrode is combined with the spectacles structure is for at least two EEG electrodes, or at least one photo sensor, 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 through The action of the eyeglass structure achieves contact between the electrode/sensor and the head and/or the ear, or the configuration of the light sensor/electrode and circuit can be achieved through an additional structure, for example, as shown in FIG. 6B, the additional The structure 60 can be implemented as a temple extending from a single side such that, for example, two EEG electrodes, an ECG electrode, and/or a photosensor contact a contact point near the one-sided auricle; or the additional structure It can also be implemented to extend from the bilateral glasses, and each has at least one electrode to contact at least two contact points near the two sides of the auricle to obtain an EEG signal, as for the ECG electrode and/or the photo sensor In any 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. In addition, go one , 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 detecting device 20 in which an electroencephalogram electrode is fitted with a photosensor, and in the embodiment of FIG. 7A, the ear-worn structure is implemented as an ear. The hanging structure 21 cooperates with the upper ear clip structure 22, wherein the ear clip structure 22 is sandwiched on the earlobe as a position for setting the photo sensor and the reference brain electric electrode And the effective EEG electrode is located at the earloop structure 21, or other parts of the earwear structure, such as the housing 23, which can be in contact with the skin near the ear or the ear to obtain an EEG signal. In principle, that is, the position of the cerebral cortex can be detected; in addition, in the embodiment of FIG. 7B, the ear-wearing structure is implemented as an earloop structure 21 and an upper earplug structure 24, wherein the light sensor And the reference EEG electrode is disposed on the earplug structure to obtain a signal by contacting the inner ear canal, the vicinity of the external ear canal, and/or the ear cavity, and the effective EEG electrode system is implemented in the earloop structure 21, Or other parts of the ear-wearing structure, for example, the housing 25, can be in contact with the skin in the vicinity of the ear or the ear to obtain the position of the EEG signal. Therefore, there are various possibilities for implementing the form. Moreover, it is also possible to implement the setting of the electroencephalogram electrode and the photosensor by a single earhook structure, that is, only the earhook, the ear clip, or the earplug structure, without limitation.

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 for the user to pass through the upper limb. The skin contact contacts the ECG detection circuit, and the other ECG electrode is configured to contact the skin near the ear or ear through the ear-wearing structure, and can be implemented to be shared with one of the EEG electrodes, or independently There is no limitation. As for the two EEG electrodes, two positions can be obtained through the earloop structure 32 and/or the housing 33 to contact the ear or the ear to obtain an EEG signal, that is, the brain can be detected. The position of the cortical activity; or, the ear clip structure may be added, for example, to the earlobe or the ear wheel, and a common reference electroencephalogram electrode and an electrocardiographic electrode are disposed therein, and the exposed electrocardiographic electrode 31 is combined with the An effective EEG electrode that is placed at the sampling position with the earloop structure.

Furthermore, the electrocardiographic electrode that requires skin contact of the upper limb can also be disposed on the finger through the finger-wearing structure, as shown in FIG. 8B, or on the wrist, or on the arm, The position near the neck, shoulders or back, as shown in Fig. 8C, shows the contact with the neck, shoulder or back skin through the neck-wearing structure to provide further convenience. Of course, it can also be implemented to contact other body parts. For example, the torso is also an alternative location.

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

Here, special attention should be paid to the special position of the electrode on the auricle. Please refer to the auricle (also known as pinna) structure shown in Figure 10, in which the inner ear of the auricle (superior concha) And around the inferior concha, there is a concha floor (ie, parallel to the plane of the skull) that is connected upwards to a vertical area of the antihelix and the antitragus. Known as the concha wall, the natural physiological structure of the ear provides a continuous plane perpendicular to the bottom of the ear, and, immediately below the wall of the ear, between the tragus and the tragus An intertragic notch, as well as an adjacent tragus, also provides a contact area perpendicular to 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 was not only sufficient for the EEG signal strength to be analyzed, but also for brain activity information. , more advantageously, when using this area as an electrode contact In position, the force required to fix the electrode will be parallel to the force at the bottom of the ear. Especially when implemented in the form of earplugs, it is natural to pass through the abutment between the earplug and the inner surface of the auricle. At the same time, stable contact between the electrode and the vertical region is achieved.

In addition, the experiment also found that the intensity of the EEG signal obtained on the back of the auricle is 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 is often provided with a component in front of and behind the auricle, and the effect is fixed on the auricle through the interaction force between the two. 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 Fig. 11, which is a schematic diagram of the location of the cerebral cortex in the skull and the position of the auricle. It can be seen from the figure that the cerebral cortex falls on the upper part of the skull and the auricle is on both sides of the skull. And prominently outside the skull, wherein, roughly speaking, separated by the 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, so in this case, through the transmission of the skull and ear cartilage, the brain wave can be measured in the upper part of the auricle, while the lower auricle is Because the distance from the cerebral cortex is farther, and the interval between the ear canals is increased, the intensity of the EEG signal becomes weaker. Therefore, in the present invention, the auricle (inside and back) is used as the brain telegram. In the sampling position, in principle, the ear canal is the boundary, the upper part of the auricle is regarded as the position where the EEG signal can be measured, and the effective electrode is suitable, and the lower auricle is regarded as the weak position of the EEG signal. 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 FIGS. 7-9. 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 the combination of the two or the three may be used to achieve the device, the electrode and the The setting of the sensor can be changed according to the actual implementation situation, and there is no limitation.

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, magnetically separated from each other by the ear. The two components are attracted together, and the electrodes and/or the sensor are disposed on the two components or one of the components. Here, the two components can be implemented to have magnetic properties, for example, magnetic substances through the interior. Or in the form of a magnetic substance itself, or in a material that is magnetically attracted, for example, one component may be implemented to have a magnetic force, and the other component may be magnetically attracted, or Both components are implemented to have a magnetic force, and various implementation possibilities are possible without limitation.

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

In particular, the eyeglass structure and the earwear structure may be further combined to provide an electrode and/or a light sensor, for example, an earplug or an ear clip may be extended from the eyeglass structure, or the eyeglass structure may have a Electrically connecting an earplug or an ear clip, as a result, there are more implementation possibilities. For example, in the case of implementing an electroencephalogram electrode with a light sensor, the electrode on the spectacles structure is in contact with the V-type. The depression, the back of the auricle, the temple, the bridge of the nose, and/or the area between the two eyes, and the electrode 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 Alternatively, it may be disposed on the eyeglass structure or the earwear structure; or, the brain electrical electrodes may be disposed on the eyeglass structure, and the light sensor is disposed on the earwear structure; In the case where the electroencephalogram electrode is combined with the electrocardiographic electrode, the exposed electrocardiographic electrode can be selectively disposed on the exposed surface of the eyeglass structure or the earwear structure, and then the electrocardiographic electrode disposed on the inner side of the eyeglass structure is matched. user The ECG signal can be extracted by connecting an earplug/ear clip to the ear, and further, the ear sensor can be combined with a light sensor. Therefore, various embodiments can be implemented. no limit.

In addition, in addition to the EEG electrodes disposed on the ear-wearing structure, the head-mounted structure, and the spectacles structure, other electroencephalogram 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 as an eye In the form of a mirror, the electrode behind the skull can also be achieved by extending the temple back. Therefore, it can be changed according to actual needs, and there is no limitation; in addition, when the electrode is provided with hair, such as the top of the head and the back of the head, You can choose to use needle electrodes or other electrodes that can pass through the hair to increase the ease of use.

In addition, other physiological signals can be additionally detected. For example, other physiological signals that are frequently monitored during physiological feedback programs 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 brain activity information, or the user may be provided for neurophysiological feedback after considering the two. The information required, as long as it can correctly and effectively express the immediate physiological state, is an alternative.

Moreover, since the level of blood pressure has a certain relationship with the activity of the autonomic nervous system, 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 illuminating sensor. (Pulse Transit Time, PTT), then calculate the reference blood pressure value through a specific relationship between the PTT and the blood pressure value, so that the user can provide an immediate blood pressure change trend during the feedback period, or provide a feedback area. The blood pressure value before and after the segment to let the user know whether the progress of the neurophysiological feedback affects the blood pressure; in addition, similarly, two photo sensors can be provided, for example, in addition to the head/ear, A light sensor is placed on the finger, and the same information is obtained by calculating the time difference between the two pulse waves.

Next, in the present invention, brain activity information and respiratory guidance signals are provided to the user through a perceptible signal generation source. Communication between the sensible signal generating source and the wearable physiological detecting device, for example, through general wireless communication such as Bluetooth, WiFi, etc. In this way, the sensible signal generating source can receive the input from the physiological detecting device disposed on the head and provide it to the user immediately, thereby achieving a neurophysiological feedback loop.

The perceptible signal generation source is configured to provide information about the user's brain activity and the respiratory guidance signal through visually perceptible signals, auditory perceptible signals, and/or tactilely perceptible signals, for example, There is no limitation on the change of the illuminating color, the illuminating intensity, the sound, the voice, and/or the vibration; and the implementation form of the sensible signal generating source can have many options. 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 display and/or audible functions, such as a cell phone, a watch, a lithographic computer, a personal computer, etc., or as A device that can be displayed, audible, or vibrated on the body, such as a single-sided earphone, a bilateral earphone, and glasses.

Alternatively, the sensible signal generating source can also be implemented as a display unit, a sounding module, and/or a vibration module combined with the wearable physiological detecting device, for example, whether using a head structure or an ear. The wearable signal generating source can be implemented as a display element 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 the brain An electric 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, and/or providing sound through an earphone coupled to the vicinity of the temple, Voice or the like; or, as an earphone, while carrying the EEG electrode and the heart rate sensing unit, also providing information through sound, or voice, and/or extending a display element or a light source to the front, Providing visual perception 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 executes a neurophysiological feedback program by using the wearable physiological detecting device of the present invention, the wearable physiological detecting device is placed on the head to transmit the brain disposed on the inner side of the headband. The electric electrode obtains the brain wave of the user, and the photo sensor obtains 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 Communicate with the illuminator, and as a result, the neurophysiological feedback program can be started.

Here, since the breathing practice and the neurophysiological feedback are combined, as described above, based on the progress of the breathing exercise, the user's breathing guidance signal is required, and based on the neurophysiological feedback, the user is required to perform the neurophysiological reaction. The feedback is given to the information of the physiological activity of the change, 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 breathing guide signal is to allow the user to follow the breathing, it is necessary to be able to express the difference between the inhalation and the exhalation. Therefore, the illumination system continuously changes the intensity of the illumination to represent the continuous change of inspiration and exhalation. For example, the gradual increase in luminous intensity is used as a guide for gradual inhalation, and the 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.

One of the options in observing the neurophysiological feedback program for relaxation is to observe the proportion of alpha waves in brain waves. In the brain wave, in general, the α wave predominates to indicate that the human body is in a state of relaxation and waking state, so the degree of relaxation can be known by observing the proportion of the alpha wave. Accordingly, after starting the neurophysiological feedback program, the illuminator provides respiratory guidance (through illuminating) Continuous change in intensity) to guide the user to adjust their breathing. At the same time, the physiological detection device worn on the head also detects the brain wave, and the obtained brain wave is calculated after a calculation. An analysis result, for example, the proportion of the alpha wave, and based on the analysis result, generates information about the brain activity of the user, and then the illuminator 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 instantly convey the change of the physiological state to the user through the change of the illuminating color based on the illuminant, for example, the color representation can be utilized, for example, the closer to the blue The more relaxed the color is, 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. As a result, the user can easily change the color. And to know that their physical and mental state is nervous or relaxed, and also follow the breathing guide while self-regulation, and make the color of the light further toward a more relaxed goal.

Alternatively, the degree of relaxation or emotional state of the human body can be understood by observing the energy balance and synchrony of brain activity in different brain regions. For example, when the body has a positive emotional response, the left prefrontal lobe The cortical 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 shown that when the human brain is in the state of alpha wave synchronization, it can achieve a clear and relaxed state of mind. Therefore, by detecting brain activity in different brain parts, for example, Fp1 and Fp2 is related to the prefrontal 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. Understand if 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 having the EEG electrode of the same device, it may 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 adjust the color change of the illuminating feedback to the user.

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 causes the brain waves to approach the low-frequency segment of the respiratory rate, for example, below 0.5 Hz. Fluctuation, therefore, in addition to knowing whether the synchronization between the two is achieved by resonance, the breathing pattern can be known by observing the brain wave, and the autonomic nerve is also caused by the sinus node and the vascular system of the heart. Systematic regulation, and the autonomic nervous system also feeds heart rate and blood pressure changes back to the brain through the baroreceptor system, which affects the function and function of the brain, for example, affecting the cerebral cortex, and can be measured by EEG. Yes, coupled with conscious control of breathing can affect the heart rate caused by the influence of autonomic nerves, therefore, there is a relationship between the three, so the good synchronization between the three can represent the body is more relaxed State, according to which the analysis of the relevant synchronicity can also serve as a self-awareness for the user Adjust the information for neurophysiological feedback.

In addition, it is also possible to detect the breathing pattern of the user by observing the fluctuation of the blood flow. For example, the pulse sensor can be obtained through a light sensor provided at a position such as an ear or a forehead to obtain a blood flow. Variety.

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 relaxed state and the consciousness is interrupted. Therefore, the ratio of the β wave to the θ wave can be increased. For the purpose of improving 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 through neurophysiological feedback. Accordingly, after the neurophysiological feedback program is started using the system of the present invention, the illuminator provides a respiratory guidance signal (through a continuous change in luminous intensity) to guide the user to adjust 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 calculate 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 user changes the illuminating color to the user immediately. It conveys changes in the function of the brain. For example, it can be represented by multiple colors. The closer to the blue, the lower the concentration. The closer to the red, the higher the concentration. The lighter the depth of the same color. The lighter the color, the more focused. The lower the force, the darker the color means the higher the concentration. As a result, the user can easily know whether his concentration is improved through the change of color and follow. Suction guide while also self-awareness regulation (self-regulation), the emission color tends to further improve the focus target.

In addition to observing the ratio of theta waves to the beta waves, the slow cortical potential (SCP) is also a neurophysiological feedback that increases concentration. For example, when treating patients with ADHD, brain activity is often observed, among them, SCP 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 converted degree of relaxation or concentration can be used as a basis for change as described above, or can be used to indicate changes in physiological signals, for example, , the proportion of the alpha wave changes, etc., therefore, there is no limit. Moreover, there is no limitation on the way the illuminating color changes. The key point is that the user can understand his or her physiological state simply and clearly, and can drive the user to self-consciously control to achieve the target physiological state.

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

In the prior art, when performing neurophysiological feedback, the feedback mode for the user is usually implemented, for example, by moving the object with the effect of performing neurophysiological feedback, for example, 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 continues to bloom because the body is more and more relaxed; or directly shows the change in measurement value; The method of introduction is mostly implemented as, for example, a waveform that passes through the up and down undulations represents inhalation and exhalation. So when combining the two At the same time, the user is easily disturbed by a visual display that is too complicated, too large, or difficult 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 through a single object when considering how to provide information to the user, so as to simplify the complexity as much as possible, and not to cause a mental burden on the user. It also makes it easy for users to use the 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 need to combine two programs and need to pay attention to the two focus issues, which helps to concentrate.

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

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

In addition, an audible sensory signal, such as sound or voice, may be additionally provided to provide another option when the user needs to close the eye for the feedback section. For example, the intensity of the volume may represent the inhalation and exhalation. Continuously changing, and through different sound types, 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, and the frequency of the sound is high or low. Representing a physiological state, for example, the higher the frequency of the sound, the more nervous, the lower the frequency, the more relaxed, and the like, and therefore, there is no limitation. Moreover, the auditory sensible signal can be implemented as being provided by the audible signal generating source and/or by the wearable physiological detecting device, again without limitation.

As for the breathing guide signal, there are also many implementation possibilities. In general breathing exercises, the types of breathing guide 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 mode that changes with time. 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 with the physiological state. Dynamically changing pattern of breathing changes. Therefore, in the present invention, the respiratory guidance signal can provide an electroencephalogram signal and/or a heart rate sequence obtained through the wearable physiological detection device, in addition to providing a preset respiratory state change pattern that is fixed and changed over time. The breathing guide signal can be implemented to dynamically change with physiological conditions to provide more effective guidance to the user toward the target physiology State of breathing change pattern.

There are various implementation options for the manner in which the user's physiological state affects the breathing guide signal. For example, by analyzing the heart rate sequence, the actual breathing behavior of the user can be known, and then the difference between the guided signal and the guided signal can be known, and the breathing guide signal can be adjusted accordingly, for example, when the user's own breathing rate is low. At the rate provided by the breathing guide signal, the breathing rate of the breathing guide signal can be lowered at this time to guide the user to further enhance the physiological feedback effect.

Alternatively, the heart rate sequence may be subjected to HRV analysis to know the situation of autonomic nerve activity, thereby inferring the degree of relaxation of the user. When the degree of relaxation has increased and remains stable, the respiratory guidance signal may be implemented to further reduce the breathing rate, for example, , from 8-10 times per minute to 6-8 times per minute, to further increase the degree of relaxation; or, it can be implemented when the user's degree of relaxation has reached the desired goal, or the control of breathing has stabilized When the breathing guide is matched, the supply of the breathing guide signal is stopped, and the user can concentrate on self-consciousness regulation, and only when the breathing is found to be unstable or the degree of relaxation is lowered, the breathing guidance is started again. Therefore, there is no limit.

In addition, in particular, it may be implemented as a program that allows the user to alternately perform respiratory regulation and change the physiological state through self-consciousness regulation through the presence or absence of the provision of the respiratory guidance signal. According to research, when the program that affects 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 multiplied. Therefore, the respiratory guidance is provided first by intermittently. The signal is used for a period of time to let the user get used to the breathing mode to achieve stable breathing. Then, by stopping the breathing guide, the user simply concentrates on the self-consciousness control program in the natural breathing mode that is used to it. Such a process will further enhance the feedback effect.

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 present invention combined with the breathing practice and the self-awareness control program, the breathing guidance can be provided without During the period in which the breathing exercises are exerted on the autonomic nervous system, it is convenient for the user to perform a self-awareness control program, and the effect of the breathing practice is increased.

Here, the alternating conversion of the breathing practice and the self-awareness control program, that is, the presence or absence of the supply of the breathing guidance signal, may be determined according to the physiological state of the user as described above, or may be based on a preset time interval. Switching is fixed, there is no limit. In addition, when the fixed switching mode is adopted, it may be further implemented that the breathing guide signal is switched between fast and slow breathing rate, for example, 6-8 times per minute and 10-12 times per minute, and such This can help, for example, focus on switching training for 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 source of the sensible signal is generated, for example, a smart phone, a tablet, a smart watch, etc., the breathable signal is provided to the user by the sensible signal generating source for the user to perform breathing exercises; or Alternatively, the sensible signal generating source may have a preset breathing change mode provided to the user, but further receives input from the wearable physiological detecting device and adjusts the respiratory guiding signal, thereby ,no limit.

According to another aspect of the present invention, it is also possible to provide brain activity information and a breathing guidance signal through an auditory sensible signal. As shown in Figure 2, the user can adjust his breathing and carry out the life through the sound breathing guidance signal and brain activity information presented on the mobile phone. Feedback.

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

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

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

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

The auditory sensible signal can also be generated by a sound emitting module combined with the wearable physiological detecting device. For example, the earphone can be implemented as a headphone or ear worn physiological detecting device. In this case, Users only need to wear a single device to get the physiological signal, but also get information such as feedback/breathing guidance, which is highly mobile and convenient, and if implemented in glasses or earwear, More aesthetic, suitable for daily use, especially suitable for closed-eye feedback section during commuting, which is quite convenient. In particular, the sound module and earphone used can be used in addition to the common air conduction form. In the form of 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, for example, in the form of bone conduction, 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 can also be implemented to provide brain activity and respiratory guidance signals through tactilely perceptible signals, for example, can be implemented to use vibration signals to alert the user to correct exhalation and/or Or inhale the start point, or only find the user The breathing mode deviates from the preset target guiding signal to generate vibration guidance, etc. In addition, different physiological states can be expressed by the strength of the vibration, for example, when the physiological feedback target is to relax the body and mind, the vibration is stronger. It means that the tension is higher, and as you relax more and more, the intensity of the vibration is also weakened.

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 provide both an audible sensible signal and a tactile sensible 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 eyes, but also affect other people around. It is quite convenient to carry out the feedback section in the case.

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 a Bluetooth device can 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 a call, and further, through the setting The vibration 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 can be further implemented as an information providing interface of 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, due to the loading according to the present invention The setting is in a wearable form, and therefore, it is also suitable for use as a brain-computer interface. In the case where the detected physiological signals mainly include an electroencephalogram signal and a heart rate sequence, there are several possible ways to generate an instruction, for example. Words, but not limited, because the proportion of alpha waves in brain waves varies greatly with the movements of closed eyes and blinks, in general, when the eyes are closed, the proportion of alpha waves is greatly increased, so This can be used as a basis for generating instructions. In addition, when the position of the electroencephalogram electrode is placed near the eye, for example, the nose bridge, the root of the mountain, the area between the eyes, and the temple, the eye movement can also be detected. Obtain an eye movement signal (EOG), so that instructions can be given by, for example, blinking, eyeballing, etc.; further, because breathing is a physiological activity that the human body can control, and as described above, Breathing not only affects heart rate (that is, the so-called RSA), but also causes fluctuations in brain waves in the low frequency range. Therefore, under the framework of the present invention, whether it detects brain wave signals or detects The rate sequence can be used to know that the user's breathing behavior pattern changes, and thus, as a basis for generating an instruction, for example, the user can issue an instruction by deliberately extending the period of inhalation, or can also deepen the breathing. Increasing the heartbeat variability rate, and then increasing the RSA amplitude, as a basis for issuing instructions, therefore, there is no limit.

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 types of instructions can be combined to make the application wider, for example, it can be applied to virtual reality games, smart glasses, etc.

Furthermore, the neurophysiological feedback performed by the device according to the present invention is also suitable for integration into the game, and therefore, in addition to changes in visual/auditory effects, for example, colors, object types, people, which change with physiological state, Sound, etc., through the way of the game, will provide more Multi-interactive content, for example, can increase the willingness to interact with users through a game software executed on mobile phones and/or computers. For example, first, a score system can be used. For example, if the goal of neurophysiological feedback is to relax the body and mind, the score can be used to express the degree of relaxation in a segment, such as the proportion of alpha waves in the brain wave. Furthermore, since the physiological feedback has a cumulative effect, the scores obtained at different times and in different sections can be cumulatively calculated, so that the user can easily know the results of his efforts through the scores, which is helpful. Develop a sense of accomplishment, and in this case, you can further set the different score thresholds that can be achieved, increase the user's desire for challenge, and, with the concept of the level, when you reach a threshold, you can reach the next level, and Open different functions, etc., increase the use of fun, and increase 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 gifts, treasures, etc., or higher levels of gameplay can be promoted, and various methods common to online games are suitable for use in the present invention.

Furthermore, due to the nature of the game, the accumulation of physiological feedback is mainly constructed on the premise of continuous use, that is, when the interval of the physiological feedback program executed is too long, the cumulative effect is lost. For example, the calculation principle of the score can be designed as, 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 the physiological feedback program for 2 days, 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 , the previous cumulative score is zeroed, In order to encourage users to continue to use.

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

Furthermore, the device according to the invention is also applicable to the acquisition of sleep related information. As is well known to those of ordinary skill in the art, electroencephalograms are the primary basis for determining sleep staging. Generally, conventional measurement methods are, for example, placing a plurality of electrodes on the scalp and connecting them through a connecting wire. One machine, but since it must be measured during sleep, this method is not convenient for the user. Therefore, if the electrode configuration can be completed through the ear-wearing form or the glasses form, it is naturally a no-burden option, and In contrast, the unburdened detection method has less impact on sleep and will result in a test result that is closer to the daily sleep situation.

Furthermore, other electrophysiological signals can be measured by adding other electrodes or by sharing the 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, the electro-oculogram can provide REM (Rapid Eye Movement). Information, myoelectric signals can provide sleep onset and sleep offset, molars and REM information, ECG signals can be used to assist in the observation of physiological state during sleep, for example, the state of autonomic nerves, cardiac activity In the case of skin electrical activity, information about the sleep stage can be provided. Further, if a photosensor is added, blood oxygen concentration can be obtained to determine the occurrence of hypopnea and/or additional action. Sensing elements, such as accelerometers, provide information on body movements and/or microphones to detect snoring situations. Therefore, through Jane A sensor that is placed on the ear can get quite a lot of information about sleep in the most unburdened situation, which is quite convenient.

In summary, the wearable physiological detecting device according to the present invention provides a breathing guide through the neurophysiological feedback section, so as to achieve the purpose of increasing the concentration of the user and enhancing the feedback effect, the two complement each other and do more with less. In addition, the electrodes and/or the sensor are also disposed on the head and/or the ear while being placed on the head and/or the ear through the structure of the headgear structure and/or the ear-wearing structure, which not only increases the convenience of use. It also greatly enhances mobility.
