Definitions
- the invention mainly concerns home support for vulnerable people (for example: seniors, people suffering from disabilities, people suffering from a chronic illness, etc.).
- vulnerable people for example: seniors, people suffering from disabilities, people suffering from a chronic illness, etc.
- the invention is also aimed at anyone wishing to monitor the evolution of their sleep over time at home.
- the invention aims to better evaluate the autonomy of people, particularly fragile people, by monitoring the evolution of their sleep using an actimetry system for the implementation of a tele-vigilance service. .
- hypersomnia of central origin for example: narcolepsy, idiopathic hypersomnia, Klein Levin syndrome, etc.
- narcolepsy idiopathic hypersomnia, Klein Levin syndrome, etc.
- idiopathic hypersomnia idiopathic hypersomnia
- Klein Levin syndrome etc.
- rhythm disorders that is to say a desynchronization between internal wake-sleep rhythms and the light-dark cycle
- sleep disorders can reveal variations or gaps in restorative sleep, and therefore indicate a loss of autonomy in the fragile person.
- sleep disorders can lead to an alteration of psychological functions, a reduction in the effectiveness of the immune system, but also increase the risks of reporting more serious pathologies such as cardiovascular diseases. Consequently, in these people, sleep disorders can also lead to a loss of autonomy, which will however have different consequences compared to fragile people (for example: loss of vigilance, difficulties at work, etc.).
- the awake stage (known as the AWK stage, for “awake” in English), which is the awake phase;
- NI stage which is a transition stage between wakefulness and sleep.
- the sleeper does not really feel like he is sleeping, he is dozing;
- N2 stage which is the confirmed sleep stage.
- An electroencephalogram recorded during sleep shows characteristic patterns which allow us to affirm that the sleeper is sleeping;
- N3 stage deep sleep, or so-called N3 stage.
- This stage is characterized, for example, by slow, broad waves on an electroencephalogram, hence its name slow-wave sleep. It is a deep sleep from which it is difficult to wake the sleeper;
- stage NI Classically, falling asleep is followed by light sleep (stage NI then stage N2) which leads on average in around twenty minutes to deep slow-wave sleep (stage N3). After about 90 minutes, paradoxical sleep appears (NR stage). These different stages constitute the first sleep cycle. A cycle lasts approximately 90 to 100 minutes. A night has 4 to 6 cycles, depending on the duration of sleep. The first half of sleep is particularly rich in deep slow-wave sleep, while the second half is essentially made up of alternating light sleep and paradoxical sleep.
- sleep means all the sleep cycles, each comprising a particular sequence of different stages of sleep, during the same night.
- sleep is structured by a certain number of cycles, each cycle consisting of different stages of sleep through which the sleeper will pass.
- different physiological parameters representative of sleep can be monitored during the night. .
- the variations in the measurement of these physiological parameters are in fact characteristic of the different stages of sleep through which the sleeper will pass during his night's sleep.
- These different physiological parameters can be analyzed using different techniques.
- polysomnography which is defined as a process of monitoring and recording several physiological parameters during sleep. Polysomnography takes into account physiological parameters such as:
- EEG electroencephalogram
- EOG electro-oculogram
- EMG electromyogram
- ECG electrocardiogram
- respiratory polygraphy is defined as being a simplified polysomnography comprising a fewer number of physiological parameters measured (but at least two parameters), most often without neurophysiological parameters (cerebral activity for example). It is mainly used to investigate sleep-disordered breathing.
- none of the techniques of the prior art makes it possible to estimate, from the detection of variations in a person's sleep, whether the quality of his sleep deteriorates over time to the point of causing a loss of autonomy.
- the invention responds to this need and proposes a method for monitoring the sleep of a user using at least one user equipment located near the user and/or worn on him, said at least one user equipment being connected to a communications network.
- This process includes:
- a user's sleep disturbance indicator comprising a first comparison of the current sleep signal to a set of curves representative of temporal sequences of sleep stages determined for a reference time period, called sleep signals of reference ;
- the invention is based on a completely new and inventive approach to monitoring the sleep of a user (for example: fragile people, or people wishing to monitor their sleep), with a view to detecting a deterioration in the quality of their sleep. sleep and decide whether it is necessary to alert the user, a person close to them or a qualified third party (for example a doctor).
- the method according to the invention compares the sleep of the user during a reference period, which corresponds to a period already elapsed during which the user's sleep was supposed to be sufficiently restorative, with the user's sleep outside this reference period, such as for example every night outside the reference period. For this, the method according to the invention determines: for a current period, such as for example a night, a current sleep signal, and for a reference period, a set of reference sleep signals (also called sleep history of the user).
- This comparison then makes it possible to identify changes in the user's sleeping habits. In other words, it is possible to identify whether the user's sleep signal during the current period (for example a night outside the reference period) is different from those of his sleep history during the reference period. Discrepancies between these signals can arise for example: the fact that the user takes longer to fall asleep (longer AWK stage), wakes up several times per night (several AWK stages during sleep time) . More generally, this comparison makes it possible to detect modifications in the sequences of sleep stages leading, for example, to a shift in sleep cycles compared to the user's sleep history, etc. An indicator of the person's sleep disturbance is then estimated from this comparison.
- This decision criterion may for example be a threshold or several disturbance thresholds to cross, the variability of the indicator over an observation period of several nights, etc.
- the solution proposed by the invention makes it possible to monitor the evolution of an individual's sleep cycles over time, and to evaluate whether their sleep habits change and in particular whether they deteriorate.
- the invention makes it possible to detect a deterioration in the quality of the user's sleep, but also to decide, depending on the importance of this deterioration, whether it is necessary to alert either the user or those around him, since the sleep disorders detected are likely to cause a loss of autonomy in this individual.
- the detection of a deterioration in a user's sleeping habits can be indicative of a loss of autonomy for this user, who is no longer able to maintain the conditions favorable to sufficiently restorative sleep on a daily basis and puts therefore his health is in danger.
- This estimate of sleep disturbance is therefore one of the strong indicators for assessing the good physical, social and moral health of individuals for tele-vigilance services.
- This estimate of sleep disturbance can also make it possible to adapt telecommunications, multimedia or home automation services, etc.
- the user by carrying and/or keeping one or more pieces of equipment close to him, is in fact adhering to the sleep monitoring solution.
- an alert notification can be transmitted directly to the user on equipment such as a connected watch, smartphone, etc. or to an e-Health service (or tele-vigilance service).
- e-Health service or tele-vigilance service
- the determination of the current sleep signal comprises obtaining at least one current set of temporal sequences of measurements of at least one physiological parameter representative of the user's sleep collected during the temporal period current by at least one sensor of said at least one connected piece of equipment.
- at least one temporal sequence of measurements of these physiological sleep parameters is collected by one or more sensors of the user equipment(s) during a current period, subsequent to the reference period, and corresponding for example to a night of sleep of the user outside the reference period.
- user equipment continuously records one or more physiological parameters representative of sleep, also hereinafter called physiological sleep parameters.
- physiological sleep parameters For example: connected watch, smartphone, etc.
- measurements of these physiological parameters are collected during sleep time (for example during a night's sleep) by one or more different, or identical, sensors of the user equipment(s). .
- sleep time does not necessarily correspond to one night in the literal sense of the term.
- sleep time means any time interval during which the user sleeps (for example from 11 p.m. to 6 a.m. or from 8 p.m. to 5 a.m.).
- night means the user's sleep time.
- the temporal sequences of current measurements thus obtained then make it possible to determine a curve representative of a temporal sequence of sleep stages during this current period, in other words, the current sleep signal.
- the measurements are collected for each night outside the reference period.
- the current sleep signal from the current period i.e., a night outside the reference period
- the method further comprises: a determination of the reference sleep signals based on obtaining at least one reference set of temporal sequences of measurements of said at least one physiological parameter collected during said reference time period by at least one sensor of at least one user equipment connected to the communication network and located near the user and/or worn on him.
- the method according to the invention comprises a determination of all the reference signals, during the reference period (for example one week).
- This set of reference signals, or the user's sleep history makes it possible to identify sleep disturbances when compared to the current sleep signal.
- one or more user equipment(s) continuously record one or more physiological sleep parameters. Measurements of these physiological parameters are then collected during the reference period by one or more different, or identical, sensors of the user equipment(s).
- Temporal sequences of measurements of physiological sleep parameters are thus obtained and used to determine for each night of the reference period, a curve representative of a temporal sequence of sleep stages (AWK, NI, N2, N3, NR), also called reference sleep signal.
- This curve, or reference sleep signal therefore represents the succession over the course of sleep time (for example during the night) of the different stages through which the user will pass during his sleep.
- a reference frame, or sleep history, comprising this set of reference sleep signals is then created.
- the user equipment used during the reporting period may be the same or different from that used during the current period. It is thus possible for the user to use different equipment depending on their precision or ease of use.
- obtaining the sleep disturbance indicator further comprises a second comparison of the current sleep signal to a sleep signal recommended for the user.
- the user's sleep disturbance indicator for a current period takes into account both a set of sleep signals obtained for this user during a reference period, but also a recommended, or "ideal” sleep signal. ”, for this user.
- This recommended sleep signal is, for example, defined theoretically and represents an ideal restorative sleep for the user based on criteria linked to their age, gender, body size, etc.
- the invention proposes to refine the estimation of the user's sleep disturbance measurement over time by comparing the current signal obtained for the individual (ground reality) to an ideal theoretical sleep signal, to accurately estimate the deterioration in the person's sleep quality compared to this model
- the method further comprises, following obtaining the disturbance indicator, an update of the set of reference sleep signals comprising a recording of the current sleep signal as reference sleep signal when said at least one decision criterion is not satisfied.
- the determination of the current sleep signal, respectively the reference sleep signals comprises an implementation of an artificial intelligence module configured to associate, from a characterization model of the user's sleep, at least one segment of the temporal sequences of measurements of the current set, respectively at least one segment of the temporal sequences of measurements of the reference sets, at at least one stage of sleep.
- the artificial intelligence module implements for example a neural network making it possible to learn to associate with segments of temporal sequences of physiological parameter measurements collected during the current period, respectively during the reference period, a stage of sleep (AWK, NI, N2, N3, NR).
- a stage of sleep ANK, NI, N2, N3, NR.
- the temporal sequences of the current, respectively reference, sets are segmented in order to be able to associate a sleep stage with each segment. It is thus possible to obtain a representation in the form of a curve of a sleep signal (also called sleep curve) of the user for a given night, either during the current period, or during the reference period.
- the artificial intelligence module makes it possible to precisely characterize the structure and/or duration of the user's sleep, that is to say the succession of cycles and, within each cycle, the stages of sleep. This makes it easier to spot significant changes in the user's sleep structure.
- the method comprises prior learning of the characterization model from a learning database associating segments of temporal sequences of measurements of at least one physiological parameter representative of sleep. a panel of users collected during a period of sleep in a controlled environment at least one stage of sleep.
- the learning of the sleep characterization model by the artificial intelligence module is done in a supervised manner from a public database associating segments of temporal sequences of measurements of different physiological sleep parameters at different stages of sleep. sleep to reconstruct all of the user's sleep cycles during a night's sleep. It is thus possible to obtain a sleep signal representative of the structure and duration of the user's sleep.
- said at least one physiological parameter is chosen from a group comprising at least: cardiac activity, cerebral activity, movements of the eyeballs, muscular activity, respiratory effort, a respiratory flow, partial pressure of carbon dioxide and/or oxygen (PaCO2/PaO2), oxyhemoglobin saturation, body position, breathing sounds.
- the first comparison comprises obtaining a first distance measurement between the current sleep signal and the reference sleep signals
- the second comparison comprises obtaining a second distance measurement between the current sleep signal and the recommended sleep signal
- - obtaining the disturbance indicator includes obtaining a weighted sum of the first measurement and the second measurement.
- obtaining the sleep disturbance indicator takes into account the differences between the user's current sleep and his sleep history and between his current sleep and a recommended sleep curve for this user. It is thus possible to personalize the estimate of a sleep disturbance for each individual monitored, taking into account that restorative sleep for this particular individual does not necessarily follow the theoretical curve of restorative sleep identically. recommended.
- said at least one decision criterion comprises at least one sleep disturbance threshold, the decision criterion being satisfied when the disturbance indicator is greater than or equal to said at least one disturbance threshold.
- At least one sleep disturbance threshold is taken into account. It is thus possible to smooth the estimate of sleep disturbance over a defined period and to eliminate disturbances which are temporary (for example linked to a particular period of life, etc.).
- a notification is issued when the disturbance indicator crosses a predetermined disturbance threshold (for example 0.5).
- a first threshold to evaluate the isolated value of the disturbance indicator for the current night and a second threshold (which may be lower than the first) to evaluate a deviation in the value of the disturbance indicator.
- sleep disturbance for example: thresholding on a Euclidean distance
- alert levels can be considered, depending on the estimated level of disturbance (that is to say for example depending on the exceeding of one or more successive threshold(s) (of increasing values) of disturbance).
- the lowest level (“low” exceeding a first level of disturbance threshold) can consist of sending personalized notifications to the person being monitored to help them get into the conditions for better falling asleep (for example, example: limit media/communications consumption after a certain time of day and/or reduce ambient lighting, heating, before bedtime, etc.).
- the highest alert level (exceeding the last “high” disturbance threshold), when the disturbances are severe and risk causing a loss of autonomy for the user, one or more alert notifications are sent to third parties.
- the invention also relates to a device for monitoring the sleep of a user using at least one user equipment located near the user and/or worn on him, said at least one user equipment being connected to a communications network.

- FIG. 6 Figure 6 schematically illustrates an example of architecture of a device for monitoring the sleep of a user within their home, according to one embodiment of the invention.
- the general principle of the invention is based on monitoring the evolution over time of a user's sleep in order to create an indicator of disturbance of his sleep and, depending on this indicator, to decide whether an alert notification must be issued.
- the invention seeks to make a robust estimate of the autonomy of a user at home by following the evolution of their sleep over time.
- the invention proposes to define a sleep disturbance indicator by comparing a sleep history of this user, obtained during a reference period and stored in memory, a sleep of the user for each night (or sleep time ) outside the reference period and so-called “recommended” or “ideal” sleep for this user.
- the sleep disturbance indicator is “weak” (for example below a predefined disturbance threshold)
- the person is judged to be “autonomous”.
- the disturbance indicator is “high” or increases over time (for example greater than or equal to the predefined disturbance threshold)
- this person is then judged to be losing autonomy.
- “Recommended” or “ideal” sleep means sleep which is considered restorative for the user according to standards of sleep structure and/or sleep duration... defined theoretically according to categories taking into account, for example the age, gender, body size, etc. of the user. Indeed, the structure of sleep (e.g. type of sleep stages, number of cycles, time spent in each stage and/or between stages, etc.) and its duration varies over time/life.
- the “ideal” newborn sleep structure is 3 stages per cycle with 50 minutes on average per cycle and the “ideal” adult sleep structure is 5 stages per cycle with 110 minutes on average per cycle.
- the 3 phases of the newborn's sleep cycle are: falling asleep, restless sleep, and calm sleep.
- the 5 phases of adult sleep are: falling asleep, light slow-wave sleep, deep slow-wave sleep, another phase of light slow-wave sleep, paradoxical sleep.
- the recommended sleep duration for those over 65 is 7 to 8 hours while for 14-17 year olds it is 8 to 1 Oh.
- the invention is therefore based first of all on the constitution of a sleep history of the user over a reference period corresponding to a succession of several nights of sleep during a given period (for example 1 week), and representing the period during which sleep is considered restorative, or of sufficient quality, for the user being monitored (so-called “normal” sleep for this user).
- This reference period is therefore the period during which the monitored user is considered to be in full autonomy.
- This sleep history therefore represents the user's sleeping habits.
- the user's sleep during this period is also hereinafter called "reference sleep”.
- This user's sleep history is then compared to so-called “current” or “daily” sleep of the user, that is to say to the sleep of this same user during a current period corresponding to a night outside. of the reference period, in order to detect a possible discrepancy.
- This so-called “current” period is separate from and subsequent to the reference period.
- This “common” sleep is also compared to “ideal” sleep, or “recommended” sleep, for this user.
- the differences detected between the user's current sleep, sleep history and recommended sleep are used to evaluate an indicator of disturbance in the user's sleep and therefore deduce a possible loss of autonomy for this user. In other words, based on this sleep disturbance indicator, it is possible to decide whether the user is losing autonomy and therefore to alert tele-vigilance services to offer personal assistance solutions. .
- measurement data of at least one physiological parameter of the user representative of his sleep are collected during the reference period, then during the current period, for example one night, in order to characterize sleep (structure and/or or duration) of the user during this reference period and during the current period.
- These data of this or these physiological parameter(s) are obtained from measurements collected by one or more sensor(s) integrated into one or more terminal equipment(s) worn by this user, or near it (for example on a bedside table) while sleeping.
- This terminal equipment(s), or user equipment(s) are connected to a communications network which allows them to transmit, where applicable, one or more alert notifications to third parties as part of a tele-vigilance service.
- FIG. 1 We now present in connection with Figure 1 an example of an environment of a user during sleep according to the invention.
- This environment may correspond for example to a bedroom in the user's home, or to a hotel room, or any place in which the user can sleep.
- the environment of the user UT includes in particular a local communication network LAN that is managed by a residential gateway NOT connected to a carrier's R_EXT data communications network.
- the LAN network is a home network, to which several user devices can be connected: tablets, smartphones, connected watches, connected headbands, etc.
- the EQ user equipment is for example a smartphone or a connected object such as a connected watch, connected bracelet, connected headband (also called brain wave headset) or any other terminal equipment equipped with a communication interface with the LAN network and of a sufficiently small size to be easily carried by the user, or at least to be close to the UT user (for example placed on a bedside table).
- a connected object such as a connected watch, connected bracelet, connected headband (also called brain wave headset) or any other terminal equipment equipped with a communication interface with the LAN network and of a sufficiently small size to be easily carried by the user, or at least to be close to the UT user (for example placed on a bedside table).
- the user equipment EQ. comprises one or more sensors, identical or different, configured to measure one or more physiological parameters different from the user during sleep.
- physiological parameters can for example be one or a combination of parameters chosen from:
- the electrical activity of the brain for example measured by electroencephalogram (or EEG) using a brain wave sensor included in connected headband type EQ equipment worn by the UT user during his sleep;
- EEG electroencephalogram
- the movements of the eyeballs for example measured by electro-oculogram (or EOG) using the camera of a smartphone of the user UT filming him during his sleep;
- EOG electro-oculogram
- - muscular activity for example measured by electromyogram using a muscle sensor included in a connected watch or bracelet;
- ECG electrocardiogram
- the sensor(s) of the EQ equipment. are configured to collect and record continuously during the sleep of the user UT data (or signals) of one or more physiological parameters representative of the sleep of the user UT.
- physiological sensors are also hereinafter called physiological sensors, and the physiological parameter data is also called physiological data, or physiological signals.
- the user can carry on him, or have near him, several different EQ equipment (for example: a connected watch worn on the wrist and a smartphone recording and/or filming him during his sleep) having different sensors to measure several different physiological parameters.
- EQ equipment for example: a connected watch worn on the wrist and a smartphone recording and/or filming him during his sleep
- the EQ user equipment used during the reporting period may be the same or different from that used during the current period.
- the user equipment(s) EQ then transmit(s) the physiological data collected by its sensor(s) to a DISP device for monitoring the sleep of a user UT, which will be described below in link with Figure 6.
- this DISP monitoring device stores in a memory the measurements of the physiological parameter(s) representative(s) of the user's sleep thus collected.
- the DISP device implements all or part of the method for monitoring a user's sleep according to the invention which will be detailed below in relation to Figure 2.
- This DISP monitoring device can be embedded in the EQ user equipment or the plurality of EQ equipment. Alternatively, the DISP monitoring device can be integrated into the user's PAS gateway which has the advantage of benefiting from greater computing and memory resources than the EQ user equipment(s).
- the DISP monitoring device can be integrated into a server in the network of the operator R_EXT.
- the transmission of physiological data is done from the user equipment(s) E to the DISP device via the network.
- LAN communication for example via WiFi®, Bluetooth® connection...
- the EQ user equipment(s) connected to the LAN communication network, the network access equipment (PAS gateway) and the sleep monitoring device of a user DISP form a system S for monitoring the sleep of a user UT.
- step 1 (sub-steps El to E6) includes:
- the physiological parameters taken into account are parameters of brain activity (EEG) and/or cardiac activity (ECG).
- EEG brain activity
- ECG cardiac activity
- other physiological parameters can be taken into account in addition to or in replacement of these.
- the data of this or these physiological parameter(s) are collected continuously by the sensor(s) of the EQ user equipment(s) as described in Figure 1; And
- a sleep characterization model by a classification module configured to characterize sleep, that is to say configured to determine the structure and/or duration of sleep, from a set labeled segments of temporal sequences of measurements, called labeled segments, of one or more physiological parameters.
- a classification module configured to characterize sleep, that is to say configured to determine the structure and/or duration of sleep, from a set labeled segments of temporal sequences of measurements, called labeled segments, of one or more physiological parameters.
- each labeled segment of temporal sequences of physiological measurements is associated with a sleep stage in the STG_DB database, so that it can then be used to train the classification module; (iii) the implementation of the characterization model by the classification module for the characterization of the user's sleep for each night during the reference period Pref from the reference sets of segments of temporal sequences of measurements, of or physiological parameter(s) of the user. It is thus possible to create a sleep history of the user, during the Pref reference period. This sleep history, representative of the user's sleep habits, is then stored in memory in an SLP_DB database;
- step 2 (sub-steps E7 to E9) includes:
- the Pref reference period corresponds to the period during which the user is considered to be in full autonomy, that is to say that their sleep is considered to be of good quality and restorative for this user (sleep said “normal” for the user).
- Step 1 therefore mainly aims to create a sleep history of the user during this reference period, in order to be able to compare in step 2 the daily, or current, sleep of the user to this history and to a sleep “recommended” for this user.
- this sleep history is updated with the sleep of the current period characterized by the classification module.
- the Pref reference period evolves over time, since each new day adds to the user's sleep history.
- the "current" sleep is identified as "normal” for this user, that is to say considered to be of as good quality and restorative as usual, then it is added to the sleep history of the user.
- the SLP_DB user (“current” sleep whose sleep disturbance indicator does not trigger an alert).
- “routine” sleep is identified as “unusual”, i.e. the sleep disturbance indicator triggers an alert, then this "common” sleep is not added to the SLP_DB history to avoid distorting its history function sleep reflecting “good” autonomy of the user.
- a sub-step El as described in connection
- a sub-step E3 for all the physiological signals of interest associated with a day j of the reference period Pref, that is to say the physiological signals of interest obtained after cutting out the sub-step E2, a window for analyzing the signals of interest is obtained. Its width is for example determined by preliminary experiments (empirical choice).
- the physiological signals of interest cut in sub-step E2 are segmented every 30 s without overlap. This segmentation is then carried out according to sliding windows for analyzing the physiological signals of interest. We then obtain a set of segments, or series, of 30 s time sequences resulting from the segmentation of the physiological signals of interest; a sub-step E4: the physiological signals of interest obtained in E2 and segmented (for example every 30 s) in E3 to obtain a set of temporal sequence segments, are then processed.
- the processing includes, but is not limited to, low-pass filtering to denoise information, normalization to standardize data, resampling of data to synchronize sources, etc.; a sub-step E5: it consists of teaching an artificial intelligence module, such as for example the classification module MOD_CLAS presented in connection with Figure 3, to classify each segment of temporal sequences of physiological signals of interest from substages El to E4 in one of the five classes corresponding to the five stages of sleep, namely the stages AWK, NI, N2, N3 and NR.
- an artificial intelligence module such as for example the classification module MOD_CLAS presented in connection with Figure 3, to classify each segment of temporal sequences of physiological signals of interest from substages El to E4 in one of the five classes corresponding to the five stages of sleep, namely the stages AWK, NI, N2, N3 and NR.
- substep E5 seeks to construct the user's sleep history including a sleep curve S(k) of the user for each night k during this period Pref.
- This STG_DB database is for example constructed by collecting physiological signals (for example: EEG, ECG, EOG type signals, etc.) from a panel of users in a controlled environment (for example in a laboratory). More particularly, this STG_DB database comprises a set of temporal sequence segments obtained after processing, as described in substeps E1 to E4, the collected physiological signals.
- physiological signals for example: EEG, ECG, EOG type signals, etc.
- Each segment of temporal sequences of physiological signals of interest from the public STG_DB database is then tagged or labeled using information identifying one of the five classes corresponding to the different stages of sleep.
- these labels, or labels are of digital type and the segments of temporal sequences of data of interest (that is to say the segments of temporal sequences of physiological signals of interest) come from the base of public STG_DB data are each associated with a label value between 0 and 4, such that: value 1 represents stage NI, value 2 represents stage N2, value 3 represents stage N3, value 4 represents stage stage NR and, the value 0 represents AWK awakening signals.
- the classification module MOD_CLAS is trained in a supervised manner to classify the segments of temporal sequences of physiological signals of interest from the STG_DB database, in one of the classes corresponding to the different stages of sleep: AWK, NI, N2, N3 and NR.
- the classification module MOD_CLAS takes as input the segments of temporal sequences of physiological signals of interest from the STG_DB database and adjusts its configuration to associate with each segment of temporal sequences of physiological signals of interest, at output, the stage of sleep corresponding to the label.
- the MOD_CLAS classification module is configured to give a value between 0 and 4 to each segment of temporal sequences.
- a sleep signal produced by the classification module MOD_CLAS with a prediction of the sleep stage for each segment of temporal sequences of physiological signals of interest over the entire sleep, for example 9 hours of sleep.
- Such learning allows it to build a sleep characterization model MC which it will then implement in the test phase to recognize the different stages of the sleep cycles of a new set of segments of temporal sequences of physiological signals from the user and obtain a sleep curve S(x).
- the MOD_CLAS module is an artificial intelligence module which presents the architecture of Figure 3. As described previously, this MOD_CLAS classification module is configured to implement the MC sleep characterization model .
- This architecture therefore takes as input data SEQ_E the segments of temporal sequences of physiological signals of interest from the user during sleep (segments obtained following sub-steps E1 to E4).
- the labeled temporal sequence segments of interest from the public database STG_DB are used as described previously.
- the segments of temporal sequences of signals of interest are obtained from temporal sequences of physiological signals collected for the user and processed, as presented in connection with sub-steps E1 to E4, during a reference period Pref.
- the trained MOD_CLAS classification module takes as input the segments of temporal sequences of physiological signals of interest from substeps El to E4 of the Pref reference period, to classify them in one of the classes corresponding to the five stages of sleep, namely the AWK, NI, N2, N3 and NR stages.
- it automatically produces at output, from the temporal succession of segments associated with a sleep stage, a sleep curve S(k) for each night k during the reference period Pref.
- sleep curves S(k) are stored in the SLP_DB database, thus constituting the user's sleep history monitored during the reference period Pref.
- the classification module MOD_CLAS comprises an ENC autoencoder configured to transform the segments of temporal sequences of physiological signals of interest at input SEQ_E into encoded signals to obtain a compact ENC_REP encoded representation.
- the MOD_CLAS classification module takes the ENC_REP encoded representations as input and associates them with a stage value between 0 and 5. As previously described, it was previously trained to make such an estimate from the ENC_REP encoded representations. input signals.
- the value represents an AWK wake state. Between 1 and 2, the value represents the NI stage. Between 2 and 3, the value represents stage N2. Between 3 and 4, the value represents stage N3. And beyond 4, the value represents the NR stage.
- the classification module finally comprises a DEC module configured to produce an output sleep signal taking the form of a curve representative of the successive stages of sleep S(x) (also denoted SEQ_S) of the user as illustrated in Figures 4 and 5.
- the MOD_CLAS module can be for example a neural network, or any other artificial intelligence module capable of performing the same functions.
- Step 1 ends with the constitution of the two knowledge bases: the database, or sleep history, SLP_DB including the sleep curves S(k) of nights k of the reference period Pref and, the base of REF_DB reference data of dimension R described previously (R representing a number of nights k re f in the REF_DB database).
- This reference database stores examples of sleep curve S(k re f) recommended for an individual according to their age, sex, body size, etc. In other words, this database is a representative database of 'an ideal sleep depending on the age category, gender, etc. of the users.
- Step 2 includes the automatic day-to-day estimation (that is to say for each night j outside the reference period Pref) of an indicator of sleep disturbance of the person, based on on step 1 completed with the constitution of the two repositories described previously (sleep history SLP_DB and reference database REF_DB) stored in memory. This last step considers a new day j, or current period, to be analyzed outside the reference period Pref.
- a sub-step E7 for at least one day j, corresponding to a current period, not belonging to the reference period Pref, and subsequent to Pref, the method according to the invention repeats the sub-steps E1 to E4 of collecting and processing the physiological signals obtained by the sensor(s) (for example EEG and/or ECG type signals) of the equipment(s) user(s). Then, sub-step E6 is implemented to characterize the user's sleep (i.e. determine their sleep curve S(j)) for day j using the MC model used by the MOD_CLAS classification module.
- Figures 4 and 5 represent in curve form different sleep signals obtained after characterization of sleep by the classification module according to the invention.
- Figures 4 and 5 represent the different stages of sleep (AWK, NI, N2, N3 and NR) through which the user passes during his sleep time.
- the solid gray curve represents a recommended sleep signal S(k re f) obtained from the REF_DB database.
- This sleep signal S(k re f) therefore corresponds to an ideal sleep for the user monitored according to, for example, their age, gender, etc.
- the black dotted curve represents an example of sleep signal S(k) obtained, as described previously, from the sleep history SLP_DB.
- the solid black curve represents a current sleep signal S(j) collected for the user during the current period, obtained as described previously.
- the sleep signals illustrated in Figures 4 and 5 are characterized by a certain number of cycles, for example 4 cycles, each cycle being composed of different stages of sleep.
- the reference sleep signal S(k) can be close to the recommended sleep signal S(k re f) ( Figure 4), or on the contrary different (Figure 5).
- E(j) is defined by the following equation:
- the first component of the equation compares the signal, or curve, of sleep S(j) of day j of the current period, to the sleep signals S(k) contained in the SLP_DB database (sleep history of the user).
- the second component of the equation compares the sleep signal S(j) of the day to the sleep signals S(k re f) contained in the reference database REF_DB (recommended sleep for the monitored user).
- the distance dist between two sleep curves, or signals, S(j) and S(k) can, in an example of implementation, be calculated as a distance DTW (from the English “Dynamic Time Warping”). The distance are normalized between 0 and 1.
- the sleep disturbance estimate E(j) takes values between 0 and 1. If its value is close to 0, this means that The analysis of the day's sleep is close to its history constituted in the reference period Pref and the "recommended" references of the set R and therefore the person is judged as “autonomous” because the person presents behavior similar to its history and recommended sleep for this user (see for example figure 4). If, on the contrary, the value is close to 1, this means that the analysis of the day's sleep differs from its history constituted in the reference period Pref and from the "recommended” references of the set R and therefore the person is judged to have a “loss of autonomy” because the person presents behavior different from their history and the recommended sleep for this user (see for example figure 5).
- the estimate, or indicator, of sleep disturbance E(j) obtained previously is analyzed to decide whether the user has a loss of autonomy linked to sleep disorders, and whether or not it is necessary to trigger a protective action in the as part of a tele-vigilance service, such as notifying a third party of the loss of autonomy observed for the current period.
- the evaluation can consist of always disseminating this information.
- the sleep disturbance estimation value E(j) determined if it is different from 0, then we consider it useful to notify that there is a sleep disturbance and therefore a potential loss of autonomy in sub-step E9 (“O” in Figure 2), and therefore we proceed to the transmission of a loss of autonomy alert notification in sub-step E9 and to the proposal of a appropriate service recommendation.
- a notification when the sleep disturbance indicator E(j) satisfies a decision criterion, such as for example a sleep disturbance threshold.
- a decision criterion such as for example a sleep disturbance threshold.
- the notification is issued when the sleep disturbance indicator E(j) is greater than or equal to a predefined disturbance threshold, for example equal to 0.5.
- the process is repeated for several successive current time periods, and subsequent to the reference period.
- each current period lasts one night.
- the process is then repeated every night outside the reference period.
- the decision to broadcast an alert is taken based on the previous disturbance threshold and at least one other criterion of decision, or relevance.
- this other decision criterion requires that the predefined threshold (for example 0.5) be exceeded several times over a period P' of several consecutive nights. We then take into account the indicators obtained over several consecutive nights.
- this other decision criterion can take into account the differences between the estimation values, or indicators, of disturbance obtained over the period P' and an average of these values during the period P'.
- the diffusion of this notification can be decided, even if the disturbance threshold is actually exceeded only a few times over the period P' (in this case of implementation, it is necessary to calculate the sleep disturbance values E(k' ) for all days k' belonging to the period P').
- Substep E9 If the decision criteria(s) of a notification are not satisfied (no or “N” in Figure 2), substep E9 is not implemented and substeps E1 to E8 are resumed directly. for a new current time period. Substep E9 therefore consists of broadcasting a notification of information on the user's autonomy as a function of the value E(j) estimating the sleep disturbance of the person being monitored for day j.
- this notification can be sent to the user to inform them of their autonomy, alert them of a lack of autonomy and/or give a recommendation to regain autonomy.
- this notification can be sent to an e-Health service, to a trusted third party (family of the person being monitored) or to a treating physician.
- a trusted third party family of the person being monitored
- a treating physician to supply applications and services linked to e-Health solutions for monitoring vulnerable people and/or for monitoring residents in their use of the smart home (such as: connected home, secure home ).
- alert levels can be considered, depending on the estimated level of disturbance (i.e. for example depending on the exceeding of one or more successive threshold(s), of increasing values, of disturbance).
- the lowest level (for example crossing a first threshold of disturbance) can consist of issuing personalized notifications to the person being monitored to help them get into the conditions for better falling asleep (for example: limiting the consumption of media/communications after a certain time of day and/or to reduce ambient light, heating, before bedtime, etc.).
- the highest level for example crossing a second disturbance threshold, greater than the first threshold
- one or more alert notifications are addressed to third parties.
- the invention allows a robust estimation of the autonomy of a person at home based on their daily sleep.
- the invention is original in the design of an end-to-end model, that is to say from raw data towards the promotion of a suitable service, with recognition of the user's sleeping habits as a reference for notify e-Health services about the autonomy of the person being monitored.
- the applications are, first of all, the estimation of autonomy for fragile people in e-Health services. This estimate makes it possible to inform the family and the medical profession of developments in the physical, moral and social health of the person being monitored for services, particularly tele-vigilance. We can also imagine future services that would favorably use the analysis of sleep cycles. Likewise, services adapted to the situation of a lone worker can be provided depending on their state of fatigue and health (e.g. alert upon arrival in a risk area for greater vigilance, etc.).

Additionally, MEM memory can store STG_DB, SLP_DB and REF_DB databases.
- the DISP monitoring device also includes a COM communication module for receiving/transmitting measurements from sensors and transmitting alert notifications on the user's autonomy.
