Description

Physiological feedback system
Technical field
The present invention relates to a kind of physiological feedback system, particularly a kind of system in conjunction with physiologic information Real-time Feedback and Respiratory control.
Background technology
In recent years, increasing research focuses on the mode how human body is regulated and controled by self-consciousness and affects the operation system of health, able-bodied effect is improved to reach, such as, physiological feedback (biofeedback) (comprising nervous physiology feedback (neurofeedback)), meditation (meditation), respiratory training (breath training) etc. are all obtained the experimental results support at present, and also have the method that more and more people uses.
Wherein, physiological feedback is a kind of human body learns how to change physiological activity learning program in order to improve the object such as health and usefulness, in this program, by consciousness in human body, such as, thinking, mood, and behavior, the physiological activity changed, such as, E.E.G, heart rate, breathe, muscle activity or skin temperature etc., can be monitored by instrument, and instrument fast and accurately by information feed back to experimenter, due to this information with relevant for the physiological change that realizes, therefore, experimenter after obtaining the information, just can carry out self-consciousness regulation and control according to this, physiological reaction needed for reinforcement.
In addition, the normal method of meditation is: focus one's attention on, concentrate the mind on breathing (mindfulness) and bowels of mercy and love, mainly all relates to self-consciousness and controls.Many congruences of the object of meditation and clinical psychology, psychologic medicine, preventive medicine and education, increasing result of study display, meditation may contribute to releive depression and chronic pain conditions, and is conducive to promoting overall happiness.
In addition, also increasing scientific evidence is had to show, the self-consciousness regulation and control carried out during meditation can change the functional loop of brain, and producing the effect that soul, brain and whole health are all benefited, many neuroscientists have also begun through the brain response during observation meditation and have understood the impact of meditating and causing for human body.And namely this be similar to so-called nervous physiology feedback (neurofeedback) to a certain extent, just, when carrying out nervous physiology feedback, the same with carrying out physiological feedback, in real time the information of brain activity can be provided and give user.
As from the foregoing, when relate to be reached by the regulatory mechanism of human body self improve able-bodied effect time, most significantly that user must focus one's attention on, with the carrying out helping self-consciousness to regulate and control, therefore, when notice is more easily concentrated, the effect that self-consciousness regulates and controls to bring more easily realizes naturally.
Generally needing in the meditation process of focusing one's attention on; usually can emphasize that contemplator must be absorbed in the rhythm of breathing; especially when occurring that thought is vacillated; notice must be concentrated on again on the breathing rhythm that a suction one tells; therefore, being absorbed in the breathing rhythm is the known method promoting notice.
Breathe when generally not realizing intervention, breathing controls by autobnomic nervous system, automatically can regulate respiratory rate and the degree of depth etc. according to somatogenic need, and on the other hand, breathe and also can control by consciousness, in limited scope, human body can control respiratory rate and the degree of depth etc. voluntarily, therefore existing research display, affect sympathetic nerve and parasympathetic balance by controlling the mode of breathing, general situation is, can increase parasympathetic nerve activity during expiration, slow down heartbeat, intake period, is then contrary.
Therefore, when needs are focused one's attention on and are absorbed in the breathing rhythm, except exhaling and the rhythm of feeling elated and exultant and reach except wholwe-hearted and stable effect because notice is revert to, also can have an impact to the autobnomic nervous system of self with the time, now, as long as breathe on the impact of autobnomic nervous system with carry out physiological feedback, nervous physiology feed back or meditate congruence time, such as, loosen body and mind, then just can very naturally allow the effect of physiological feedback attain a yet higher goal because increase controls breathing, reach complementary effect.
Also due to breathe between consciousness and noncoconscious control between characteristic, respiratory training be considered to be equally a kind of can because affect human body operate and reach the program improving body and mind effect.Generally speaking, respiratory training adjusts the process of self breathing, for example, common a kind of respiratory training mode is Bu Taike respiratory training (Buteyko breathing technique), it advocates by carrying out nose breathing and making the breath method that respiratory rate or respiratory capacity reduce to realize control, can to the disease caused because of respiration rate increase or overventilation, such as, asthma, or other breathe relevant disease, such as, Sleep Apnea, has result for the treatment of.
In addition, respiratory training also can carry out when having external guidance signal, usually, the effect of steering signal is the breathing of guiding user, such as, guiding respiratory rate, and/or exhale and time ratio venting one's pent-up feelings etc., and according to the difference of object, the content of steering signal also can change to some extent, such as, when carrying out Bu Taike respiratory training, steering signal can provide slower respiratory rate, to meet its training objective.
General in respiratory training process, user many is absorbed in the adjustment of carrying out breathing, since but the object of respiratory training is also to improve physical and mental health, therefore, if can user be provided in respiratory training process about the real time information of its physiological status, know to allow user whether the carrying out breathing adjustment advances towards the set goal, believes the efficiency that can contribute to promoting respiratory training further, reaches the effect of getting twice the result with half the effort.
Therefore, really the system needing to develop a kind of novelty is had, can be controlled by self-consciousness user and carry out physiological feedback, meditation or nervous physiology feedback time, the foundation of carrying out further breathing adjustment is provided, to make breathing can be demonstrated out on the able-bodied impact of improvement simultaneously, and then allow attainable effect more top building with complementing each other.
In addition, when based on respiratory training, the same mode by allowing user learn the physiological status of self in real time, and allow user while carrying out respiratory training, its Respiratory behavior or other physiological status can be changed by autopsychic regulation and control, the effect of further training for promotion.
Summary of the invention

Detailed description of the invention
The object of present system is, both the program of physiological status and Respiratory control is affected warm in same training section by being adjusted by self-consciousness, and realize by the mode of interactive formation one backfeed loop between user the technique effect that addition affects physiological status, therefore various the regulation and controls by self-consciousness such as physiological feedback, nervous physiology feedback, meditation and/or respiratory training can be widely used in and affect the program of physiological status, obtain lifting further with the effect allowing this program realize.
Under this principle, system according to the present invention has a Wearable physiological sensing device and can produce source by perceptual signal, wherein, this Wearable physiological sensing device is in order in this training section, obtain the affected physiological signal because physiological activity changes, and this can produce source then in order in this training section by perceptual signal, can perceptual signal by user, such as, vision can perceptual signal, and/or aural perceptible signal, to provide respiratory daoyin and the information about physiological activity to user, such as, real time physiologic status, the change of Respiratory behavior, and/or the effect etc. that training performs.
Refer to Fig. 1, one preferred embodiment of its display system according to the invention, this embodiment is to provide about nervous physiology reponse system incorporates the implementation content of respiratory training, therefore, at this, this Wearable physiological sensing device is embodied as a wear-type EEG checking device 10, and this can perceptual signal generation source be embodied as an illuminator 12.
When user utilizes this nervous physiology reponse system of the present invention and performs a nervous physiology feedback process, as shown in figure, this wear-type EEG checking device is arranged on head, to be obtained the E.E.G of user by the electrode for encephalograms be arranged at inside headband, at this, the setting position of electrode for encephalograms does not limit, as long as the corresponding sample point of the specific cerebral cortex position of E.E.G can be obtained, such as, common sample point comprises Fp1, Fp2, O1, O2 etc., or any position defined according to 10-20 system, and, the setting position of electrode for encephalograms and quantity can determine according to the object of carried out nervous physiology feedback, such as, the quantity of electrode can be increased and carry out the measurement of the multichannel brain signal of telecommunication, or electrode can be set on ear with as a reference point etc., therefore, not restriction.
Afterwards, again this illuminator 12 is arranged at the position that health front eyes can be seen naturally, and the EEG checking device on head and this illuminator are linked up, such as, by communication as bluetooth, WiFi etc., can start to carry out physiology of respiration feedback process.
At this, owing to combining respiratory training and nervous physiology feedback, therefore, based on the carrying out of respiratory training, user's respiratory daoyin signal need be provided, and based on nervous physiology feedback, then need to provide user to react to perform nervous physiology feedback and the information of physiological activity that changes and/or other relevant information, and the medium that namely this illuminator is to provide.
In this embodiment, the signal of the allowed user perception that this illuminator produces comprises luminous intensity and glow color, to represent different information respectively, wherein, luminous intensity is in order to show respiratory daoyin, and glow color is then in order to show the change of user's physiological activity.
Object due to respiratory daoyin signal is that allowing user followed by breathes, therefore need can show air-breathing and feel elated and exultant between difference, therefore, this illuminator is represented air-breathing and the consecutive variations of feeling elated and exultant, such as, strengthen the guiding as air-breathing gradually gradually using luminous intensity, and weaken the guiding as feeling elated and exultant gradually gradually using luminous intensity, thus, user just can clearly and easily followed by and carry out compressing.
When carrying out loosening the nervous physiology feedback process for target, wherein the ratio in E.E.G shared by α ripple is observed in a kind of selection.In E.E.G, generally speaking, when α ripple is preponderated, representing that human body is in the waking state loosened, therefore can learn by observing α ripple proportion the degree loosened.Accordingly, after starting to carry out nervous physiology feedback process, this illuminator provides respiratory daoyin (consecutive variations by luminous intensity), adjust it to guide user to breathe, the same time, EEG checking device on Dai Yutou also carries out the detection of E.E.G, acquired E.E.G is then after the calculating through a calculation formula, an analysis result can be drawn, such as, α ripple proportion, and the information producing an associated user brain activity according to analysis result, then, namely this illuminator changes its glow color according to the information of this associated user brain activity.
For example, can program at the beginning time first obtain an a reference value, such as, α ripple accounts for the percentage of total E.E.G energy, again the result of analyzed gained and this reference value are compared afterwards, with the relation drawn and between this reference value, such as, ratio increases or reduces, and this illuminator can pass on the change situation of its physiological status based on this in real time to user by the change of glow color, such as, multiple color can be utilized to represent, more loosen as more close blueness represents, more close redness represents more nervous, also can the depth of same color be foundation, the more shallow representative of color is more loosened, color represents more nervous more deeply, thus, user just can learn simply by the change of color that the physical and mental statuse of oneself is nervous or loosens very much, and self-consciousness regulation and control (self-regulation) are also carried out while following respiratory daoyin, and make glow color tend to the target more loosened further.
Alternatively, also by observing the energy balance situation of brain activity between two and half brains and synchronism to understand degree of relaxation or the mood state of consciousness of human body; Or, the number of CBF in cerebral cortex can be detected and learn the vigorous degree of brain activity, to judge the degree of relaxation etc. of body and mind.
In addition, when to improve absorbed power for target, then can select the ratio of observing θ ripple and β ripple.In E.E.G, β ripple represents when preponderating that human body is in and regains consciousness and the state of anxiety, then represent when θ ripple is preponderated that human body is in loosen and realize the state of interrupting, therefore, the object improving and be absorbed in power is reached relative to the ratio of θ ripple by improving β ripple, such as, namely wherein a kind of method for the treatment of ADHD (Attention deficit hyperactivity disorder, attention deficit ADHD) patient is the ratio that the mode fed back by nervous physiology observes its θ ripple/β ripple.Accordingly, utilizing system of the present invention after starting to carry out nervous physiology feedback process, this illuminator provides respiratory daoyin signal (consecutive variations by luminous intensity), adjust it to guide user to breathe, the same time, the upper EEG checking device of Dai Yutou also carries out the detection of E.E.G, to analyze the ratio of θ ripple and β ripple further, such as, θ ripple and β wavelength-division do not account for the ratio of total E.E.G energy, or calculate θ/θ+β and β/θ+β etc., afterwards, the information of an associated user brain activity state is produced according to analysis result, and this illuminator is namely based on the information of this associated user brain activity, and passed on the change situation of its brain function in real time to user by the change of glow color, such as, multiple color can be utilized to represent, more close blueness represents that absorbed power is lower, more close redness represents that absorbed power is higher, also can the depth of same color be foundation, it is lower that power is absorbed in the more shallow representative of color, it is higher that color represents absorbed power more deeply, thus, user just can learn simply by the change of color whether the absorbed power of oneself improves very much, and self-consciousness regulation and control (self-regulation) are also carried out while following respiratory daoyin, and make glow color tend to further improve the target be absorbed in.
And except the ratio of observing θ ripple and β ripple, SCP (SCP, slow cortical potential) be also improve during the nervous physiology being absorbed in power feeds back the brain activity often observed, wherein, the negative offset (negative shift) of SCP is relevant to the notice comparatively concentrated, and the forward migration of SCP (positive shift) is then relevant to the notice of reduction.
So, physiological status representated by this glow color, can be embodied as various may, such as, can as described above using through convert after loosen or absorbed degree as change foundation, or can in order to represent the change of single physiological signal, such as, the ratio change shared by α ripple, or the change etc. of brain activity, therefore, not restriction.And the variation pattern of glow color, also without certain restriction, focuses on allowing user can simply and be well understood to oneself physiological status, and can use and order about user and carry out self-consciousness regulation and control, to reach targeted physiological condition.
In addition, alternatively, this glow color also can be used to other information representing relevant behaviour in service, for example, the number during training can accumulated in order to expression, such as, darker color represents that the training time of accumulation is longer, with the accumulative effect that the physiological feedback program allowing user understand tool cumulative effect is brought, and at this, this accumulated time can be the accumulation of a period of time, such as, in one week, or when time accumulated time etc. of training, can change according to user's demand; Such as, or this glow color also can be used to indicate the time of each training section initial, deepens gradually from incipient light color, moves closer to training coda to represent.Therefore be all feasible mode, not restriction.
Such as, moreover this illuminator also can be embodied as the time that can set training section, 10 minutes, 15 minutes, and at the end of the time automatic shutdown, thus, user more intently can carry out Respiratory control and self-consciousness controls, and more contributes to reaching of target effect.
Therefore, pass through present system, user and can be controlled by self-consciousness and affect the program of physiological status very naturally in conjunction with Respiratory control, need not learning procedure especially, and wherein very important reason is just, this can perceptual signal produce source produce can comprise two kinds of information by perceptual signal, such as, in Fig. 1 embodiment, the vision that this single illuminator produces can show respiratory daoyin signal and real time physiologic status two kinds of information by luminous intensity and glow color by perceptual signal respectively.
In the prior art, when carrying out nervous physiology feedback, the feedback system for user can be embodied as usually, for example, the object of movement is produced along with the effect of execution physiological feedback, such as, float skyborne balloon, and when health more loosens, it is higher that balloon wafts; Or the figure to change with physiological status, such as, the flower bloomed can be continued because health more and more loosens; Or the change of direct display measurement numerical value; There is provided that the mode of respiratory daoyin then more to be embodied as, for example, by the waveforms stands air-breathing of dipping and heaving and feel elated and exultant.Therefore, when both combining, user be easy to because of too complicated, change excessive or do not allow the vision display mode of intelligible numerical value and be interfered, may increase the stress of user even on the contrary, effect does not rise counter falling.
In addition, also a kind of prior art is had, if application number is for shown in the U.S. patent application case of US6212135, the feeling elated and exultant when form through illuminator guides user to carry out respiratory training, feel elated and exultant suspend, air-breathing and inspiratory apnea, but its mode that describes, only can show the Respiratory behavior pattern allowing user follow, cannot with the time allow user know its impact that health is caused of the respiratory training that carries out, therefore be only applicable to carry out simple respiratory training.
So, for these possibility produced problem above-mentioned, the present invention is when considering how to provide information to give user, namely have selected the mode being represented two kinds of information by single object, simplify complexity as much as possible, do not allow user produce mental burden, allow user be easy to just can use native system yet.The advantage that display mode disclosed in this invention has comprises:
1. the size variation of luminous intensity, similar with the representation of general rhythm, the rhythm, user through thinking conversion, intuitively need not can obtain and guide and control air-breathing and feel elated and exultant.
2. glow color is the physiological status representation be readily appreciated that for user, compared to directly providing numerical value change, human body is for the change utilizing color category and/or depth change etc. to represent degree, grade, be easy to produce acceptance, therefore more naturally can respond and make self-consciousness regulation and control.
3. the focus of vision only has one, does not have the problem that should be noted that two focuses in conjunction with two programs, more contributes to focusing one's attention on.
Therefore, in conjunction with two kinds of issuable complexity of program, by well-designed can perceptual signal manifestation mode, can be excluded, not only effectively reduce the burden sense of user in time using, also therefore achieve the novel feedback process of effect addition.
When implementing, this illuminator can have various enforcement to select, such as, in appearance and modeling, can be spheroid as shown in Figure 1, also can be other shapes such as square, pyramidal, and further, also the form floating through magnetic force can be embodied as, increase and use interest; In addition, it is except being embodied as whole illuminator all except luminescence, also can be embodied as only part luminous, as shown in Figure 2 A, this illuminator represents its luminescent behavior through the light-permeable part being arranged at top, and this light-permeable part also can be embodied as different moulding, to cause the interest of user, such as, multi-level annular concentric (Fig. 2 B), or radial moulding (Fig. 2 C) etc., unrestricted.
And except utilizing the form of single illuminator and luminous intensity and glow color change are provided, also realize by other devices with a display func, for example, it can be the light emitting source on a screen, such as, panel computer, mobile phone, wrist-watch, the screen etc. of PC, further, this light emitting source also can be embodied as a part for image, such as, the head of humanoid figure's picture, or abdominal region etc., contribute to user and imagine activity in body when self-consciousness regulates and controls, in addition, except the form of entity light source, aperture is also good form of implementation, such as, the aperture of humanoid head contributes to user equally and imagines.And when the light emitting source be embodied as on screen described above or aperture, also can represent the change of luminous intensity further by the diameter change of light emitting region, as shown in Figure 2 D, to strengthen guiding air-breathing and the effect of feeling elated and exultant.Therefore, can be changed according to actual status of implementation, not restriction.
In addition, also aural perceptible signal can be additionally provided according to system of the present invention, such as, sound or voice, when carrying out feedback process to need user to close one's eyes, there is provided another kind of to select, for example, air-breathing and consecutive variations venting one's pent-up feelings can be represented by the intensity of volume, and by different sound kinds, such as, tweedle, sound of sea wave etc., or different song and represent different physiological status; Such as, or also carry out air-breathing by voice instruction user and feel elated and exultant, and representing physiological status by sound frequency height, more the sound of high frequency represents more nervous, and more low frequency represents and more loosens, therefore, not restriction.Further, aural perceptible signal can be embodied as and can be produced source and/or provided by this Wearable physiological sensing device by perceptual signal by this, does not limit equally.
Further again, this respiratory daoyin signal also can be embodied as and changes according to the physiological status of user and adjust in real time.In general respiratory training, the type of respiratory daoyin signal is mainly divided into three kinds, and one is preset fixing respiratory variations pattern, and such as, respiratory rate is set as fixing 8 times per minute; One for presetting time dependent respiratory variations pattern, and such as, in 1 training section of 15 minutes, respiratory rate is set as 5 minutes 10 times per minute above, middle 5 minutes 8 times per minute, and the last 5 minutes speed of 6 times per minute; And another is then the respiratory variations pattern of the dynamic change with physiological status.Therefore, in the present invention, this respiratory daoyin signal is preset as except fixing and time dependent respiratory variations pattern except providing, by the physiological signal acquired by this Wearable physiological sensing device, such as, EEG signals in Fig. 1 embodiment acquired by EEG checking device, this respiratory daoyin signal just can be embodied as with physiological status dynamic change, to provide the respiratory variations pattern more effectively guiding user's head for target physiological status.
The mode that the physiological status of user affects this respiratory daoyin signal can have many selections.For example, when the degree of relaxation of user increased and maintain stablize time, respiratory daoyin signal can be embodied as and reduce respiratory rate further, such as, from 8-10 time per minute, is down to 6-8 time per minute, to increase degree of relaxation further; Or, the control that also can be embodied as when the degree of relaxation of user has reached re-set target or breathe stably coincide respiratory daoyin time, cease breathing the providing of steering signal, and user can be absorbed in carry out self-consciousness regulation and control, only find to breathe there is not only instability or degree of relaxation but also reduce time, just start again to carry out respiratory daoyin, therefore, not restriction.
Moreover, in particular, also can be embodied as, specially allow user alternately carry out Respiratory control and to be regulated and controled by self-consciousness and change the program of physiological status by the presence or absence provided of respiratory daoyin signal.As previously mentioned, according to research display, when affecting the program of physiological status when carrying out being regulated and controled by self-consciousness, particularly nervous physiology feedback, during meditation, if breathe and can be in smooth-going and stable state, the effect that then feedback produces can obtain to add to be taken advantage of, therefore, user is allowed to be accustomed to this breathing pattern by first providing respiratory daoyin signal a period of time off and on, to reach the stable of breathing, afterwards, again by the guiding that ceases breathing, and allow user carry out self-consciousness regulatory process naturally continuing merely to be absorbed under the breathing pattern be accustomed to, such flow process can promote the effect of feedback further.
And, because respiratory training has deferred reaction for the impact of autonomic nerve, therefore, by providing the mode of steering signal off and on, coordinate upper the present invention in conjunction with the characteristic of respiratory training and self-consciousness regulatory process again, during the impact of respiratory training on autonomic nerve can be allowed not providing respiratory daoyin to present, allow user carry out self-consciousness regulatory process easily, and allow the effect of training obtain addition.
At this, alternately changing of respiratory training and self-consciousness regulatory process, that is, respiratory daoyin signal provide nothing, can determine according to the physiological status of user as described above, also can be the time interval according to presetting, switch regularly, not restriction.In addition, when adopting the fixing mode switched, also can be embodied as further, respiratory daoyin signal be fast in respiratory rate and slow between switch, such as, 6-8 time and 10-12 time per minute per minute, such mode then can contribute to, such as, be absorbed in the training that power switches, reach control ability more flexibly.
At this, obtain the wear structure of EEG signals with should be noted that, except adopt as shown in Figure 1 wear except form, also other form can be embodied as, as namely Fig. 3 shows the embodiment being worn vibrational power flow electrode for encephalograms by ear, in this example, electrode for encephalograms wears the skin of structure and ear or ear near zone by ear, and then obtain EEG signals, therefore, be mode quite easily equally, also unrestrictedly.
Then, conception according to a further aspect of the invention, also by detect user Respiratory behavior and as the basis of the information provided about user's physiological status.As shown in Figure 4 A, user is by being arranged at the respiratory movement sensing element 20 of belly and being positioned over the screen with a light emitting source 22 before body and carrying out respiratory training program, wherein, the effect of respiratory movement sensing element is to experience the body cavity that respiratory movement causes and rises and falls, thus available information comprises, but be not limited to, feel elated and exultant, feel elated and exultant and suspend (exhalation pause), air-breathing and inspiratory apnea (inhalation pause) point other duration, respiratory rate, user be adopt abdomen formula or thoracic breathing (that is, during air-breathing, gas mainly causes belly or chest expansion), throughput (so-called depth of respiration), and apnea (control pause) time etc., at this, spendable respiratory movement sensing element comprises, but be not limited to, RIP bandage (Respiratory Inductance Plethysmography (RIP, respiratory inductive plethysmograph) effort belt), and piezoelectricity breathes bandage (piezo respiratory effort belt) etc.
So, when the system by such as Fig. 4 A carries out respiratory training program, enforceable a kind of form is, difference between the Respiratory behavior pattern providing user itself actual and respiratory daoyin signal, to carry out the foundation of self-consciousness regulation and control as user, for example, difference between the two can utilize the mode calculating mark to draw, such as, the difference between the actual Respiratory behavior pattern of user and steering signal is calculated by the calculation formula preloaded, such as, can for respiratory rate, during expiration/intake period ratio etc. analyze, mark higher expression difference is less, lower then expression difference is larger, the height of mark is represented again with the change of color, such as, the height of mark is represented with the consecutive variations of same shade or different colours, learn in real time to allow user, and then make real-time adjustment.
Another kind of enforceable form provides relevant user to breathe the information of stability.Loosen because stable breathing contributes to maintaining body and mind, also can loosen and stable state in representing that body and mind is in a certain extent, therefore, by learning relevant information of self breathing stability, help user equally and carry out self-consciousness regulation and control, for example, the presentation mode of stability can represent as described above by the mode of mark, such as, the rate of change of respiratory rate can be calculated by the calculation formula preset, such as, within every 1 minute, calculate once, the rate of change lower expression stability is higher, mark is namely higher, and change glow color jointly, or draw mark by the stability of observing breathing amplitude, or using respiratory rate with breathe the result of amplitude comprehensive assessment as feeding back foundation, in addition, also by glow color direct representation respiratory rate or the change of breathing amplitude, therefore, not restriction.
Another enforceable form provides the information that relevant throughput changes.Usually when carrying out respiratory training, except respiratory rate, the size of throughput is also the emphasis that should be noted that, because the object of a part of respiratory training is the problem solving hyperpnea hyperventilation (hyperventilation), and, when breathing in daily life, if can maintain steadily and not excessive throughput, also contribute to allowing body and mind maintain and loosen and state stably, thus during by providing related breathing throughput information and carry out the foundation of oneself's adjustment as user.For example, predeterminable have a standard value, and the result compared with this standard value is presented by glow color give user, such as, glow color can remain unchanged always, and only exceeding this standard value at the throughput recorded just occurs color change, or, also can be that glow color is more deeply felt and shown that to exceed standard value more, the value and more shallow expression is more near the mark; In addition, also can not preset standard value, by means of only the glow color depth or continuously color change carry out the size of throughput.
Another enforceable form is, provides relevant user to carry out the information of abdominal respiration or thoracic breathing.Research is had to point out, abdominal respiration is adopted to contribute to increasing parasympathetic activity, can further strengthen affects autonomic nerve and reaches the effect loosening body and mind, so, when by respiratory movement sensing element is arranged at chest and/or belly, just can use and differentiate belly and other expansion situation of thoracic portion when breathing, to adjust the reference of Respiratory behavior as user, such as, separately respiratory movement sensing element can be set in belly, to understand the fluctuating situation of belly, or separately respiratory movement sensing element is set in chest, whether occur rising and falling (carry out the prerequisite of abdominal respiration in hope under) to understand chest, or as shown in Figure 4 B, respectively at chest and belly, respiratory movement sensing element 20 is all set, in addition, some training for abdominal breath is required of to be breathed for privileged site, and such as, upper abdomen or lower abdomen, this is then can be arranged at the position of belly and the detection demand that reaches for different parts by adjustment respiratory movement sensing element.And when the information providing user to be correlated with, for example, glow color then can be utilized to represent be arranged at the throughput size detected by respiratory movement sensing element of belly, or, also can represent that the respiratory movement sensing element being arranged at chest is no and detect that chest is expanded, or, also can represent the ratio etc. of belly and chest degrees of expansion, therefore, not restriction.
In addition, then, relevant user carries out the information of breathing by nose and/or oral area to the information that another kind can provide.Generally speaking, preferably breathing pattern is breathed by nose, when oral area participation breathing or when breathing by means of only oral area, breathe by means of only nose because throughput can be greater than, will easily cause hyperpnea hyperventilation, moreover, when sucking air by nose, air can be heated and humidification, and particle can filter out by the cilium of vibrissa and nose inside simultaneously, prevents it from entering in lung.According to report display, a lot of people is breathed by oral area unconsciously, therefore, only need change such situation consciously, just can return to utilizes nose to breathe, therefore provide such information also to contribute to allowing user breathe in more accurate mode when carrying out respiratory training, the effect of training for promotion.And when the information providing user to be correlated with, for example, user can be allowed to learn when carrying out respiratory training by the change of color, the presence or absence of oral area throughput and/or the ratio etc. of nose throughput and oral area throughput, can change according to actual demand.At this, for differentiating the respiratory airflow of oral area and nose, the sensing element that can detect outlet, nose variations in flow need be utilized, such as, respiratory air flow pipe or mouth and nose pipe, can detect the change of mouth, nasal respiration air-flow, and the thermal sensor be arranged between mouth and nose, the variations in temperature etc. of respiratory air flow can be responded to.
Moreover, because breathing can have an impact to autobnomic nervous system, and then make the heartbeat also controlled by autonomic nerve occur change, i.e. uneven (the Respiratory Sinus Arrhythmia of so-called sinus rate, that is intake period can make the phenomenon palpitating quickly and then make between respiratory period heartbeat to slow down RSA), therefore, another kind can obtain the mode of the Respiratory behavior of user is measure heart rate.Generally speaking, when breathing and heartbeat is in synchronous regime (synchronization) each other, just respiratory variations is learnt by analyzing heart rate sequence.
The common mode obtaining heart rate sequence comprises, but be not restricted to, heart rate sequence is obtained by detecting arterial pulse, such as, be arranged at ear, finger, wrist, the optical sensor that forehead equipotential is set up, directly be placed in eparterial pressure sensor, and arm-rest belt etc. all can obtain arterial pulse, at this, optical sensor refers to have photocell and light receiving element, and utilize PPG (photoplethysmography, light Volume Changes graphy figure) principle and obtain the sensor of light signal, such as, utilization penetrates mode or reflection mode carries out gauger, in addition, also heart rate sequence is therefrom obtained by measuring electrocardiogram, such as, by being arranged at both hands, ear and other positions of health, finger and other positions of health, and first-class at least two electrocardioelectrodes of trunk and obtain electrocardiogram, as namely Fig. 5 A shows the embodiment being obtained electrocardiosignal by two finger-worn type electrocardioelectrodes, Fig. 5 B shows the embodiment being obtained electrocardiosignal by contact ear and wrist, and Fig. 5 C shows and wears by the hand touching ear hung on ear electrocardioelectrode that device exposes and obtain the embodiment of electrocardiosignal, therefore, various selection can be had, also can change according to actual user demand, not restriction.
So, conceive according to a further aspect of the present invention, the information of giving user is provided by glow color, also can comprise by obtaining heart rate and RSA information and the information of the many relevant autonomic nerve derived, for example, known according to research, between breathing and heart rate, harmonious and synchronism represents heart beat rhythm that is more orderly and that coordinate preferably, namely, human body is in compare and loosens, stable state, therefore, whether harmonious and synchronous with between heart rate and in order to judge the effect that respiratory daoyin is trained and/or as the information providing user in real time by being breathed by analysis, such as, frequency-domain analysis can be carried out to heart rate sequence, represent that when frequency spectrum is more concentrated synchronism is higher between the two, or the phase difference that also can calculate between the two, when phase difference more hour represents that synchronism is higher between the two, therefore, analysis result about harmony analysis matrix or synchronism can be presented to user by the depth of same color and the change of different colours, such as, color more shallow expression harmony analysis matrix/synchronism is higher, health more loosens, and on the contrary, color is darker, represents that harmony analysis matrix/synchronism is lower, user can be learnt in real time, and whether its respiratory training/physiological feedback carried out advances towards the target loosened, moreover, also adjust respiratory daoyin signal by analysis result, to guide the breathing of user further, and make physical and mental statuse tend to the target more loosened gradually.
Alternatively, also can be embodied as shown in Figure 4 C, in respiratory movement sensing element, electrocardioelectrode 24 is set again, and obtain heart rate sequence by electrocardiogram, by the information of the related breathing behavior acquired by respiratory movement sensing element on coordinating again, the analysis result of harmony analysis matrix as above and synchronism can be obtained equally, therefore, not restriction.
Further, owing to obtaining RSA information by heart rate sequence, therefore go back observable heart rate, breathe and EEG signals between synchronism (synchronization), with as feedback foundation.According to research display, exhale and can cause the fluctuation of Ink vessel transfusing blood volume with air-breathing, and this fluctuation also can arrive brain along with blood flow, and then cause E.E.G at the low frequency section close to respiratory rate, such as, lower than 0.5 hertz, fluctuation, therefore, whether realize except synchronism because of resonant interaction between the two except learning, also therefore breathing pattern can be learnt by observing E.E.G, in addition, because the SA node of heart and vascular system are by the regulation and control of autobnomic nervous system, and, the change of heart rate and blood pressure also can be fed back to brain by pressure receiver system (baroreceptor system) by autobnomic nervous system, and then affect function and the running of brain, such as, affect cerebral cortex, and can be recorded by electroencephalogram, add control breathing consciously and can cause alteration in heart rate because affecting autonomic nerve, therefore, the relation affected each other is there is between three, it is event, synchronism good between three can represent human body and be in the state comparatively loosened, accordingly, the analysis result of this related synchronization can be used as the information providing user to carry out self-consciousness adjustment equally, to carry out nervous physiology feedback.
Therefore, as shown in Figure 6, just optical sensor can be incorporated on the wear-type EEG checking device in Fig. 1, such as, wear structure 14 by ear and be arranged on ear, such as, ear clip structure, or be arranged at inside headband and obtain heart rate sequence etc. by forehead, thus, by more kinds of physiological signals, can have the physiological status of user and assess more accurately, nature can provide the real time information of more closing to reality physiological status, and user can more easily be advanced towards targeted physiological condition.
In addition, except common to be reached by respiratory training is loosened except the object of body and mind, also other object is reached by regulation and control breathing, for example, because RSA amplitude is relevant to parasympathetic activity, larger RSA amplitude representative preferably parasympathetic activity, and when the increase of parasympathetic activity is abundant, that just can trigger human body loosens reaction (Relaxation Response), remove the pressure of accumulation, therefore, by observing the changes in heart rate pattern of user, and when heart rate starts to accelerate, inform that user can start air-breathing by respiratory daoyin, and when heart rate starts to slow down, inform that user can start to feel elated and exultant by respiratory daoyin, to reach the effect increasing RSA amplitude, so, there is provided user to contribute to triggering the respiratory daoyin signal that human body loosens reaction by such mode, now, then on coordinating, such as, glow color represents the information whether breathing of user matches with respiratory daoyin signal or the information etc. whether parasympathetic activity increases, and the effect of respiratory daoyin can be allowed further to obtain and promote.In addition, the size of amplitude acquired by the crest of RSA and trough, that is, in a respiratory cycle, difference between the maximum of heart rate and minimum, Hui is relevant to the active height of autonomic nerve, therefore, this information can be provided in real time equally and give user, to regulate the basis of physiological activity as user.
Further again, after obtaining heart rate sequence, also can carry out HRV (Heart Rate Variability, heart rate variability rate) analyze, HRV analysis is then a method of the common approach learning autobnomic nervous system activity, such as, frequency-domain analysis (Frequency domain) can be carried out, general power (the Total Power assessing overall heart rate variability degree is can be used to obtain, TP), high frequency power (the High Frequency Power of parasympathetic nerve activity can be reacted, HF), sympathetic activity can be reacted, or sympathetic nerve and parasympathetic nerve regulate and control low frequency power (the Low Frequency Power of result simultaneously, LF), and the LF/HF (low high frequency power ratio) etc. of sympathetic/parasympathetic active balance can be reacted, in addition, also can after carrying out frequency analysis, the state distributed by observed frequency and learn the harmony analysis matrix that autonomic nerve operates, or, also time-domain analysis (Time Domain) can be carried out, and obtain the SDNN that can be used as the index of overall heart rate variability degree, can be used as the SDANN of the index of long-term overall heart rate variability degree, can be used as the RMSSD of the index of the overall heart rate variability degree of short-term, and can be used to R-MSSD, NN50 and PNN50 etc. of assessing high frequency closedown among heart rate variability degree.
Therefore, the result of giving the relevant HRV of user and analyzing also is provided in real time by the change of glow color, using as the information allowing user learn the activity situation of autonomic nerve, at this, because HRV analysis analyzes heart rate sequence in a period of time, therefore, the carrying out that real-time HRV analyzes is implemented by the concept of traveling time pane (Moving Window), that is, first determine one computing time section, such as, 1 minute, or 2 minutes, afterwards, by the continuous mode that this time section is passed backward, such as, within every 5 seconds, calculate once, just obtain HRV analysis result sustainably, such as, within every 5 seconds, obtain a HRV analysis result, thus the object that real-time HRV analysis result is provided is realized, in addition, also the concept of weighted calculation (weighting) can be adopted, moderately increase comparatively close to the calculated specific gravity of the physiological signal of analysis time, real-time physiological situation is more pressed close to allow analysis result.
Moreover, conception according to a further aspect of the present invention, by the biosensor of user's Respiratory behavior can be detected, also can be embodied as according to system of the present invention and user is provided himself Respiratory behavior pattern, with the actual breathing situation allowing user know oneself, such as, provide by the consecutive variations of this luminous intensity user actual respiratory rate and during exhaling/intake period change etc.Now, the real time physiologic status information provided by glow color, according to the difference of the biosensor of institute user, different possibilities can be had, for example, can be the information of related breathing behavior equally, such as, it can be the change of respiratory rate, breathe stability, the ratio of expiration and intake period, the size of throughput, whether meet abdominal respiration behavior, oral area/nose throughput change etc. are various may; In addition, also can be other physiologic information, such as, when analyzing by obtaining heart rate sequence, just can obtain the Respiratory behavior pattern of user on the one hand, and obtain other physiological state information such as autonomic nerve activity situation as the aforementioned and RSA relevant information on the other hand; Or, also can obtain physiological state information by another kind of physiology sensing element again, such as, obtain EEG signals simultaneously and learn the situation etc. of brain activity, therefore, not restriction.
And except above-mentioned various possibilities, also can be embodied as the comparison result providing the difference between the actual breathing pattern of user and respiratory daoyin signal and one to preset classification form, for example, this default classification form can be provided as the difference comparison basis between respiratory rate, such as, diversity factor is divided into blueness: 0-20%, green: 20-40%, yellow: 40-60%, red: 60-80%, therefore, user just knows the difference between the breathing of oneself and respiratory daoyin signal by the color presented, and then carries out breathing adjustment.
Further, in this case, also can again can perceptual signal and respiratory daoyin signal is provided by a sense of hearing, such as, sound or voice, with outside the physiological state information presented by glow color, also the basis of the Respiratory behavior pattern of self is adjusted as user, and/or allow user understand between the breathing (through the luminous intensity person of representing) of oneself and respiratory daoyin signal (through the aural perceptible signal person of representing) whether mutually to coincide, and make the effect of respiratory training obtain further to promote.At this, it is noted that this aural perceptible signal can be produced in the perceptual signal source that produces by this, also can be produced by this Wearable physiological sensing device, not restriction.
In addition, according to conception on the one hand again, system of the present invention also understands the physiological status of user during physiological feedback program by detecting the physiological signal movable relevant to autobnomic nervous system, to give user's information as Real-time Feedback, and/or as adjusting the basis of respiratory daoyin signal.As shown in Figure 7, in physiology of respiration reponse system according to the present invention, this Wearable physiological sensing device 30 is embodied as the electrode 31 by being arranged on two fingers and detects the electrodermal activity (EDA of user, Electrodermal Activity), this is because, electrodermal activity is relevant with the activity of sweat gland, and the secretion of sweat gland only affects by sympathetic nerve, and when sympathetic activity increases, sweat gland activity increases, and the mode therefore by measuring electrodermal activity learns orthosympathetic activity increase and decrease.In addition, in such a system, this can perceptual signal generation source be then enforcement one smart mobile phone 34, user is given respiratory daoyin signal and the information of carrying out needed for physiological feedback to be provided by aural perceptible signal, and when being embodied as employing audible means, advantageously, user can select to close eyes during physiological feedback to tool, especially when the target of physiological feedback loosens health, will advantageously.
Be with should be noted that, except finger tip, electrodermal activity also can be obtained by other positions, and such as, palm, wrist etc. are also all the common positions obtaining electrodermal activity, wherein, when with wrist for obtaining position time, be preferably, then electrode can be embodied as be arranged on as in Fig. 7 in order to arrange the inner side of the belt body of housing 32, to contact the skin of wrist, the complexity of wiring also can be reduced thus.
So, when carrying out physiological feedback program utilizing the system of Fig. 4, electrode is arranged on two fingers by user, to obtain skin pricktest signal, loosen health, and the sound presented by mobile phone is breathed steering signal and physiological feedback information and adjusts the breathing of self and carry out physiological feedback.
At this, can include, but not limited to for example in order to the aural perceptible signal showing respiratory daoyin signal, can utilize produce voice signal the time interval and as initial air-breathing with feel elated and exultant guiding; The change of sound frequency or volume can be utilized to represent air-breathing and the consecutive variations of feeling elated and exultant; Or air-breathing can be represented by different sound kinds and feel elated and exultant, such as, different music track, or there is periodically variable audio files, such as, sound of sea wave etc., to allow user's adjustment breathing with its conversion; Or also inform by voice that user should carry out air-breathing or feel elated and exultant, such as, indicated by " air-breathing " and " feeling elated and exultant " voice meeting air-breathing and time point venting one's pent-up feelings and guide the breathing pattern of user.
And when aural perceptible signal is used to show the information of carrying out needed for physiological feedback simultaneously, it has many selections equally, for example, can utilize sound frequency or volume uprise gradually or step-down represents and more and more tends to target, or, can be represented by specific sound kind or melody and not yet reach or reach target; Or, also inform by voice whether the carrying out of user's physiological feedback tends to target gradually.Therefore, distinguish as long as can make with respiratory daoyin signal, not restriction.
So, when the target of physiological feedback is for loosening body and mind, wherein a kind of embodiment is, the bleep utilizing interval to produce starts carry out air-breathing or feel elated and exultant to guide user, and utilize the height of sound frequency to represent the degree of relaxation of health, such as, the higher expression of audio frequency is more nervous, audio frequency is lower, represents and more loosens, therefore, when user hears the bleep of high frequency, just can follow carry out air-breathing with feel elated and exultant while, learn that oneself is still too nervous, need to try every possible means to loosen body and mind, so, even if by single voice signal, can clearly allow user understand two kinds of information contents equally simultaneously.
Or, another kind of embodiment can be, the power of wave volume is utilized to represent air-breathing and the consecutive variations of feeling elated and exultant, and utilize different sound kinds to represent the degree of relaxation of health, such as, representing that tensity is higher with tweedle, and represent with sound of sea wave and comparatively loosen, is the mode can knowing expression equally.
And except by detection of skin electrical activity to carry out except physiological feedback, other physiological signals by autonomic nerve Activity Effects are also feasible, for example, heart rate is because being subject to the regulation and control of sympathetic nerve and parasympathetic nerve, and when sympathetic activity increases, heart rate accelerates, when parasympathetic nerve activity increases, heart rate is then slack-off, therefore learns active growth and decline situation between the two by observing heart rate sequence; In addition, because the blood vessel being sent to acral body skin only affects by sympathetic nerve, and when sympathetic activity reduces, vessel retraction reduces, caliber becomes large, blood flow increase, skin surface temperature rise, therefore also by temperature sensor measurement limbs end slightly skin temperature and know by inference sympathetic nerve relative to parasympathetic activity increase and decrease; In addition, muscle tone is also relevant with the activity of autonomic nerve, and electromyographic electrode also can be utilized to obtain electromyographic signal, to detect the tension force of muscle, and learns loosening all muscles state; Moreover the height of blood pressure is also relevant with autonomic nerve, therefore, by the change of pressure value or the mode calculated by obtaining pulse wave passing time (PTT) with reference to pressure value, and the activity situation of autonomic nerve can be learnt.So, as long as the physiological signal that can reflect autonomic nerve activity is all applicable, not restriction.
And, in physiological feedback program, the information of the relevant physiological status of giving user is provided, except directly showing physical relaxation, nervous state as described above, other also can be had to select, such as, can be used to show through the result calculated or compare, the effect of physiological feedback, or the physiological signal directly measured by performance.
For example, can be rising or the decline of EDA numerical value, whether SA reduces and/or reduction degree etc., or, further, it is comparative result with the physiological status of not carrying out before physiology of respiration feedback that this real time physiologic status also can be embodied as, namely, physiology of respiration is fed back the physiological status before carrying out as a benchmark, and namely presenting of this real time physiologic status be and comparing difference between this benchmark, such as, an initial skin electrical activity before can feeding back starting physiology of respiration (such as, present with resistance value) be considered as 0, afterwards, during carrying out physiology of respiration feedback, measured electrodermal activity all compares with this initial skin electrical activity, when both subtract each other draw on the occasion of time, just represent that resistance value increases, that is, sympathetic activity reduces, and when subtract each other draw negative value time, just represent that resistance value reduces, that is, sympathetic activity increases, so, by such mode, the impact of physiology of respiration feedback for autonomic nerve can be presented equally.
And when being expressed by sound, except such as above by sound frequency, volume, sound kind, outside the various modes of voice etc., also can be embodied as the sound representing physiological status only just to produce when physiological status is eligible, for example, can this reference value be main, the sound representing physiological status only in resistance value lower than this reference value, that is, reflect sympathetic activity to increase, when tensity increases, just occur that warning user needs to loosen, if resistance value is always higher than this reference value, represent that user continues to maintain the state loosened, therefore, namely maintain and do not sound, or, also can be embodied as on the contrary, the sound representing physiological status continues to produce always, only just stop when tensity exceedes this reference value, therefore, not restriction.
Moreover, also can outside aural perceptible signal, increasing vision can perceptual signal, using providing as the third information, for example, when detection has two kinds of physiological signals or can obtain two kinds of physiologic informations simultaneously, except going out except physiological status in order to comprehensive descision, also the physiological status representated by two kinds of signals, information separately can be represented; Or, also can be used for representing the breathing situation of user reality as previously mentioned, know difference etc. between the breathing of oneself and respiratory daoyin signal to allow user.This vision can then provide by foregoing illuminator, screen with a display func or device etc. by perceptual signal, not restriction.
And further, this respiratory daoyin signal equally also can be embodied as and changes according to the physiological status of user and adjust in real time.For example, as previously mentioned, when the degree of relaxation of user increased and maintain stablize time, namely respiratory daoyin signal reduces respiratory rate further, to increase degree of relaxation further; Or when the degree of relaxation of user has reached re-set target or breathe control stably coincide respiratory daoyin time, what cease breathing and guide provides, and user can be absorbed in carry out self-consciousness regulation and control, only find to breathe there is not only instability or degree of relaxation but also reduce time, just start again to carry out respiratory daoyin; Or specially allow user alternately carry out respiratory training and physiological feedback etc. by the presence or absence provided of respiratory daoyin.Therefore can change according to actual use situation, or allow user select suitable mode voluntarily, unrestricted.
In addition, be with should be noted, this can produce source and also further can be embodied as and combine with this Wearable physiological sensing device by perceptual signal, such as, the display element that this Wearable physiological sensing device has, and/or a sounding component, to provide vision can perceptual signal and/or aural perceptible signal, therefore, not restriction.Moreover, in particular, when this can the perceptual signal source that produces be embodied as independent illuminator as shown in Figure 1 time, due to its independently characteristic on entity, therefore, also can be embodied as by arranging a switch, such as, a button or pulling part, or, start by shaking especially, therefore, not restriction.
In addition, the physiological feedback (nervous physiology feedback) carried out according to apparatus of the present invention and/or respiratory training are also applicable to incorporating in game, so, when performing, except the change of vision/auditory effect, such as, the color changed along with physiological status, object kenel, personage, sound etc., through the mode of game, the content of more interactions can be provided, such as, can pass through the Games Software performed on mobile phone and/or computer, increase and interest interactive between user, and then promote use wish.For example, first, point system can be adopted, such as, if the target of nervous physiology feedback loosens body and mind, then mark just can be used to show in a section, the increase degree loosened, as the ratio that α ripple in E.E.G increases, moreover, because physiological feedback has cumulative effect, therefore, different time, different mark that section obtains just can accumulate calculating, thus, user can learn the achievement of self-efforts easily through mark, contribute to cultivating sense of accomplishment, and in this case, also can set attainable different mark door further, increase the challenge desire of user, and, the concept at the outpost of the tax office can be coordinated, after reaching a door, the next outpost of the tax office can be arrived, and open different functions etc., increase and use interest, also promote and use wish.
In addition, except the concept at the outpost of the tax office, also can adopt the mode that award is provided, for example, after mark accumulation reaches certain door, more how selectable character moulding can be increased, such as, more how removable clothes kind, there is the ring of light etc., or accessory, treasure etc. can be gifted, or can promote the grade of player and give higher game capabilities etc., the common mode of various game on line is all suitable for the present invention.
Moreover, due to different from general the game feature, under the cumulative bad of physiological feedback is mainly built in the prerequisite used continuously, that is, when the interval time of performed physiological feedback program is long, namely the effect of accumulation is lost, accordingly, for example, the calculating principle of mark just can be designed to, the mark of accumulation can reduce along with the elongated gradually of the time interval, if play every the oversize time, then mark will make zero, user must start in accent, such as, when user be separated by within 2 days, do not carry out physiological feedback program time, namely running summary of the points scored is reduced to 75%, be separated by and do not use for 3 days, mark reduces to 50%, by that analogy, when finally within 5 days, not using when being separated by, namely previous running summary of the points scored is made zero, the use continued to encourage user by this.
Therefore, through the mode of game, becomes except allowing physiological feedback program more interesting except, user also can be allowed to feel in real time, and physiological status that physiological feedback causes changes, and then allows user think there is target, increases the power of use.
At this, emphatically, foregoing embodiment is only that citing is described use, is not construed as limiting, and can combine each other or replace between different embodiment, all still belongs to the present invention institute for scope of disclosure.
In sum, according to physiological feedback system of the present invention, combine Respiratory control and physiological feedback two kinds of programs novelly, by respiratory daoyin signal is introduced in physiological feedback program, except can allow spirit more concentrated except, the characteristic that can affect autonomic nerve is breathed based on conscious carrying out, the effect of physiological feedback also can be allowed more to show, both complement each other, get twice the result with half the effort, moreover, can provide the single kind of physiological feedback information and respiratory daoyin signal two kinds of information can perceptual signal by adopting simultaneously, also allow user in the process of carrying out physiological feedback, clearly and easily can understand the information content, the carrying out of physiological feedback program becomes more convenient, therefore, present patent application can bring improvement for prior art really.
