In particular, improvements can be focused on safety, comfort and entertainment or infotainment. In such autonomous or semi-autonomous vehicles, passengers and drivers are required to have more free time. There is an interest in using this free time in the vehicle in a positive way.

[3] In addition, examples of existing systems make it possible to assess the physiological or emotional state of an occupant of a motor vehicle. It is in fact known to perform measurements making it possible to determine various parameters concerning an occupant, and thus to deduce therefrom a data representative of his physiological or emotional state.

A known model makes it possible to obtain, from the various parameters, a mapping of the passenger's emotional state. Thus, this can be represented by a point in a two-dimensional space formed by an abscissa axis corresponding to the valence (intrinsically pleasant or unpleasant quality of a stimulus or a situation) and a corresponding ordinate axis to the arousal (strength of the emotional stimulus).

[63] INTERACTIVE SYSTEM

Referring to Figure 1, the invention relates to an interactive system 1 with one or more users U occupying a motor vehicle 100, driver and / or passenger (s). Such an interactive system 1 makes it possible to implement at least in part a method of interaction with the user U, described in more detail below.

[64] The interactive system 1 makes it possible to supervise one or more sessions of a remedial exercise which can be carried out by a user U in the vehicle to improve his physiological or emotional state. In addition, the interactive system 1 can possibly play on the multisensory environment of the user U, so that he has a better perception of the remedial exercise. [65] The remedial exercise can be a meditation exercise or a relaxation exercise. One could consider a leisure exercise in a domain of interest of the user U.

[66] It may alternatively be exercise in a primarily therapeutic setting. In particular, therapeutic exercise may be an exercise in repetitive movements or repetitive actions that do not require the physical presence of a health specialist, therapist, nurse or doctor. For example, without limitation, a therapeutic exercise can be chosen from one of the following fields: speech therapy, optometry, orthoptics, rehabilitation, or even physiotherapy, concentration, breathing.

[67] Advantageously, the interactive system 1 can be configured to automatically select and propose an application of a remedial exercise to the user U which corresponds to his physiological or emotional state. As an alternative or in addition, the interactive system 1 can be configured to specifically adapt the remediation exercise to G user.

[68] To do this, the interactive system 1 comprises one or more interfaces 3 for interacting with a user U, a measuring device 5, and a processing unit 7 on board the motor vehicle 100, configured to be connected to the interface or interfaces 3 and the measuring device 5.

[69] "Connected" means a computer link of the processing unit 7 with the interface 3 or interfaces 3, and the measuring device 5, so as to be able to exchange data. It can be a wired or wireless link. The data exchange can for example be done by a CAN network for "Controller Area Network" in English, LIN BUS, Wifi, Bluetooth, or others.

[70] The interface 3 can be embedded in the motor vehicle 100. Such an interface 3 is generally called a man-machine interface, known by the acronym HMI for "human-machine interface" in English.

[71] As a variant or in addition, the interactive system 1 can include a mobile terminal 9, such as a smart phone known by the English name “smartphone” and can be configured to be connected to the processing unit 7 of the computer. motor vehicle 100. Such a mobile terminal can include an interface 3 for interacting with the user.

[72] The interaction can be done by sound and / or by image and / or by tactile feedback. [73] In a non-exhaustive way, at least one command input interface and one output interface can be provided. The output interface may or may not be the command input interface.

[74] In particular, the interactive system 1 can include at least one display interface 3. A display interface allows, for example, the display of a drop-down menu allowing the user to navigate and choose from several options. The interactive system 1 can have one or more display interfaces 3 which can take the form, for example, of one or more portable devices, such as a watch and / or glasses and / or a bracelet and / or a belt and / or a shirt.

[75] A display interface 3 in the form of a screen which may or may not be touch-sensitive, may also be provided. The touchscreen can act as both a push-button control input interface, or user U touch, and a display output interface.

[76] The interface 3, or at least one of the interfaces provided, makes it possible to receive one or more notifications for the attention of the user U, in particular concerning at least one application available on the server 11. One or more notifications can also make it possible to inform the user U about his physiological or emotional state, following an analysis of data obtained by the measuring device 5, as described in more detail below.

[77] The measuring device 5 comprises one or more sensors configured to implement one or more measurement phases of the interaction method described below.

[78] The sensors of the measuring device 5 are in particular configured to acquire at least one parameter linked to G user or several users. Such an acquisition can be done at any time, in particular before, during or after the execution of an application, or even depending on whether the multisensory environment is modified or not.

[79] User-related parameters can include at least one user G physiological parameter. In a non-exhaustive and non-limiting manner, the physiological parameters can be vital signs, such as the heart rate, the pulse, the respiration, or even the coloring of the skin on the face to detect a blood flow.

[80] The sensors are preferably on-board sensors in the motor vehicle 100. The presence of the automotive sensors in the vehicle can be linked to infotainment in the vehicle, to safety and comfort factors. [81] They may be contactless sensors with user U or contact sensors.

[82] The sensors can comprise one or more cameras, for example in the visible domain, vital signs sensors, one or more microphones.

[83] At least one microphone can record the voice of user U or users in motor vehicle 100.

[84] The sensors, in particular for vital signs, can for example be in the form of contactless sensors such as, for example, a radar or a camera. Alternatively or in addition, the sensors can be provided in portable elements (watch, shirt, bracelet, etc.), worn by the user U.

[85] One or more cameras may be provided to identify facial expressions or postures of User U.

[86] At least one camera can be a time of flight camera or "time of flight" in English.

[87] In a preferred embodiment, one or more cameras, may in particular be infrared cameras configured to take images in the infrared range. These cameras are for example directed towards the expected positions of the various occupants of the vehicle: driver's seat, passenger seat, rear seat, etc. In particular, one or more very wide-angle cameras (for example of the known “fish eye” type. under the name “fish-eye” in English) can cover several positions simultaneously. Infrared cameras preferentially detect wavelengths between 0.7 pm and 100 pm, preferably 25 pm and 100 pm.

[88] These cameras advantageously include near infrared cameras "NIR" for "Near Infra Red" in English, and / or far infrared "FIR" for "Far Infra Red" in English.

[89] The images from NIR, near infrared cameras, can for example be used to delimit the position, dimensions and movements of different parts of the body of a user U of the vehicle. The images from FIR, far infrared cameras, can for example be used to identify the parts of the body of the user U exchanging the most heat with the passenger compartment, for example the head and the hands, which are not covered with clothing and thus appear warmer. [90] According to a particular embodiment, the interactive system 1 comprises a short-range ultra-wideband radar. The frequency of the radar can for example be between 10GHz and ITHz, preferably between 50GHz and 160GHz.

[91] Vital signs sensors in contact with the passenger may also be used. They come, for example, in the form of conductive elements installed in parts of the vehicle (armrest, steering wheel, seat, etc.). These vital signs sensors can be configured to measure parameters such as heart rate and / or heart rate, respiratory rate and / or amplitude, skin conductivity, brain waves, etc.

[92] As a variant or in addition, other types of parameters can also be recovered by means of other sensors.

[93] The measuring device 5 advantageously makes it possible to determine the environment of the passenger (s), which may influence the physiological or emotional state of the passenger (s). Thus, data such as temperature, light intensity, noise, vehicle speed, etc. can be collected.

[94] The measuring device 5 can also include biosensors capable of detecting parameters such as organic compounds, ions, bacteria, or the like.

[95] In addition, at least one sensor of the measuring device 5 can be configured to take performance data from user U during a session of the remedial exercise. It can be, without limitation, to follow the evolution of the position and / or movements made by the user, for example of his eyes, of a limb, of a part of the body, of monitoring his breathing on a session, or other.

[96] Furthermore, the processing unit 7 can include one or more processing means configured to implement at least in part the interaction method described below.

[97] In general, the processing means can comprise one or more of the means from among one or more telecommunications or telematics means, a comparator, at least one computer, a processor and / or any other equipment making it possible to execute software or not, an integrated circuit specific to an application known by the acronym ASIC, a read only memory known by the acronym ROM, a random access memory known by the acronym RAM, or other memory, or even other conventional or personalized hardware. [98] The modules of the processing unit 7 described below may include one or more of these processing means. In addition, the modules as defined below are differentiated to better highlight their functionalities, of course the processing means may or may not be common between different modules of the processing unit.

7.

[99] By way of example, the processing unit 7 can include an interpretation module configured to receive one or more parameters linked to the user U from one or more sensors of the measuring device 5.

[100] The interpretation module can be configured to define, from the parameter (s) obtained by the measuring device 5, a data representative of the physiological state of the user. To do this, the processing unit 7, in particular the interpretation module, is configured to use a model for evaluating the physiological state of G user U.

[101] In particular, the processing unit 7, in particular the interpretation module, can be configured to define, from a predefined number of parameters linked to the user, in particular physiological parameters, a data representative of the emotional state of the user U using a model for evaluating the emotional state of the user

U.

[102] According to an exemplary embodiment, the data representative of the emotional state corresponds to a point in a space for characterizing the emotional state of G user

U. As shown schematically in Figure 1, the space for characterizing the emotional state of user U can be a three-dimensional space. This three-dimensional space for characterizing the emotional state is formed by a first axis corresponding to the valence

V, with a second axis corresponding to the arousal A and a third axis corresponding to the dominance D.

[103] Alternatively, the space for characterizing the emotional state of user U, could be a two-dimensional space formed of a first axis corresponding to the valence and a second axis corresponding to the arousal.

[104] The valence V characterizes the level of pleasure (V +) or inconvenience (V-) associated with an emotion. In other words, the valence makes it possible to characterize how an individual experiences a situation, positively (V +), by being happy, or negatively (V-), by being sad, angry, unhappy. [105] Arousal A can be defined as the intensity of the response generated by a situation, an emotion. In other words, the arousal makes it possible to define whether the individual lives the situation with a lot of excitement (A +), or on the contrary with little excitement, if he is relaxed, asleep, passive (A-).

[106] Dominance D, on the other hand, characterizes the level of mastery and control over an individual's response to this emotion. In other words, dominance makes it possible to characterize whether the individual is in control, responsible for his reaction and his actions (D +) or on the contrary if he is overwhelmed, impulsive, under the control of his emotions (D-).

[107] An example of the mapping of the emotional state in three-dimensional space A, V, D is represented in FIG. 1. In this example, W corresponds for example to a state of anxiety, X corresponds for example to a state of ecstasy, Y corresponds for example to a state of serenity, Z corresponds for example to a state of depression. The point of intersection of the three axes of three-dimensional space A, V, D corresponds to the neutral position of the emotional state of user U.

[108] The processing of the emotional assessment model can be improved. In particular, the mapping can be modified by taking into account the impact of the culture and / or education of the occupant, making it possible to obtain a user profile for each user U. The mapping can also be adapted by taking take into account the impact of the personal life and / or user experience U.

[109] In addition, the processing unit 7 may include a data communication module with a server 11 in which is notably stored a library of applications for managing remedial exercises, at least one piece of data representative of a. physiological and / or emotional state being for example associated with each application. The applications of the library are intended to be downloaded on demand in the motor vehicle 100.

[110] The processing unit 7 can include a data processing module configured to select, among the applications of the library and according to one or more data representative of the physiological and / or emotional state of the user. U and the data representative of a physiological e / or emotional state associated with each application, at least one application for managing a remedial exercise to be carried out by the user U to improve his physiological and / or emotional state. [111] The processing unit 7 may include an information module configured to notify the user, via one or more interfaces 3, of at least one piece of information relating to the selected application (s). The processing unit 7, for example the information module, may include one or more processing means for detecting a validation action by the user U via the interface 3, for example by pressing on a touch screen, or by selection via a wheel or a touchpad, of the notified application.

[112] The interactive system 1 can accommodate applications available on the server 11. To this end, the processing unit 7 can include a download module for downloading the application validated by the user U, from the server 11. The interactive system 1 comprises an operating system making it possible to run the application, downloaded on request from the server 11.

[113] The processing unit 7 comprises at least one processing means for detecting an execution command of the application by G user U via interface 3.

[114] According to an advantageous option, the processing unit 7 can include an analysis module designed to analyze the physiological or emotional state of G user U when he performs the remedial exercise, and deduce how to adapt this. exercise specifically for the user, so that he can tend to an optimal state.

[115] To this end, the analysis module is configured to compare data representative of the physiological state of G user obtained from parameters related to the user recorded by the measuring device 5 before and during the execution. of an application. The analysis module, based on the comparison results, can determine whether an adjustment of the remediation exercise is necessary, and adjust at least one parameter of the remediation exercise.

[116] The parameter to be adjusted can be chosen from the type of at least one sequence, the duration of at least one sequence, the intensity of at least one sequence, the speed of at least one sequence or the execution or not of at least one sequence.

[117] The processing unit 7 may further comprise a performance study module configured to receive performance data obtained by the measuring device 5 during a session of the remedial exercise, and to evaluate the performance of user U and / or his progress with respect to at least one previous performance.

[118] The processing unit 7 may include a memory medium on which one or more data are intended to be recorded, such as parameters linked to the user U, data representative of the physiological or emotional state of G user U, performance data. As a variant or in addition, one or more data may be intended to be downloaded onto a data storage medium, external to the motor vehicle 100, and intended to be analyzed by a processing means external to the motor vehicle 100 and / or to be consulted. by a medical or health team.

[119] In addition, the interactive system 1 can include a telecommunication module by telephone and / or messaging and / or video, so as to allow the user U to interact with a team of specialists in the field of the application. downloaded when the application is executed, for example during a sequence of carrying out the remediation exercise. The telecommunications module can be embedded in the motor vehicle 100 or as an alternative be integrated into the mobile terminal 9.

[120] Advantageously, the interaction with the user U can also take place by multisensory stimuli, in particular by means of equipment, physical elements in the motor vehicle 100, for example by massage and / or a vibration and / or by adjusting at least one aeraulic parameter of an air flow intended to pass through the passenger compartment, such as the temperature and the flow rate, of the temperature of a device or physical element in the vehicle such as the steering wheel or a seat, the surrounding odor, the lighting in the passenger compartment, or the sound environment.

[121] To this end, the interactive system 1 may include at least one actuator configured to activate at least one multisensory stimulus to interact with G user U, so as to modify the physiological or emotional state of user U.

[122] Multisensory stimuli are for example based on the five senses: sight, smell, touch, hearing, taste. The multisensory stimuli used can, for example, be, for sight: the use of interior lighting with lights of different colors and / or different intensities; for the sense of smell: the use of a nebulizer or a diffuser for the diffusion of perfume, essential oils or even pheromones; to touch it: the use of radiant panels, water nebulization, use of hot and / or cold air jets; for hearing: the selection of sounds, or music or ambient noises; for the taste: the diffusion of perfume or nebulization which can create pheromones combining the five main flavors, namely salty, sour, bitter, sweet, umami. Other types of stimuli can be considered. [123] At least one sensor of the measuring device 5 can be configured to detect a parameter related to the user, for example before and during the application of a stimulus.

[124] The interpretation module of the processing unit 7 can be configured to define, from the parameters recorded, the data representative of the physiological state of the user before activation of the stimulus and when the stimulus interacts with the user. 'user.

According to a first aspect, the interaction method makes it possible to choose and propose an application of a remedial exercise to be performed by the user U according to his physiological or emotional state.

[128] To this end, the interaction method includes a measurement phase M during which one or more parameters related to user U, in particular physiological parameters of user G U, are acquired. This measurement phase M can be carried out by at least one sensor of the measurement device 5 of the interactive system 1 described above. The measurements can be carried out simultaneously or one after the other for different users in the motor vehicle.

[129] The measurement of at least one parameter linked to user U can be done at any time, in particular before, during, after the execution of the application of a remediation exercise. Optionally, the measurement can also be done before, during, after the application of a stimulus.

[130] Parameters describing the environment in which the user U is located can also be recorded, collected so as to deduce their possible effect on the physiological or emotional state of the user U. [131] The measurement phase M of at least one parameter linked to the user U can be implemented prior to the execution of the application and in addition when the application is executed.

[132] The data obtained during the measurement phase M can be transmitted to the memory medium internal to the motor vehicle 100 or to a storage medium external to the motor vehicle.

[133] The interaction method can include a reception and interpretation phase I of the parameter (s) obtained during the measurement phase M. This reception and interpretation phase I can be performed by the processing unit 7 of the interactive system 1, in particular the interpretation module of this processing unit 7.

[134] During the reception and interpretation phase I, a piece of data representative of the physiological state of the user U is defined from the parameter (s) received, by means of the evaluation model of the physiological state of the user. G user U. The physiological parameters are modeled so as to obtain data representative of the physiological state of G user, in particular of his emotional state. Representative data can be represented in an emotional state characterization space, such as a three-dimensional space, using the Emotions Assessment Model.

[135] FIG. 3 illustrates an example of the placement of the representative datum described above and obtained by means of the processing unit 7, in the characterization space, such as the three-dimensional space A, V, D. This datum varies during the time spent by the user U in the motor vehicle 100. Thus, a first representative datum is supplied at a time to and the representative datum supplied at a time t corresponds to the present. Continuous measurements are preferably carried out, so as to obtain the curve shown in Fig. 3. However, discrete measurements can also be carried out.

[136] Once the representative data has been evaluated, an analysis or processing step can be carried out, so as to determine the physiological or emotional state of the user U, for example according to the placement of the representative data on the characterization space, such as the three-dimensional space A, V, D. This analysis step makes it possible to map the physiological or emotional state of the user U and to decide whether or not an action is necessary to improve the state of G user U. [137] Referring again to FIG. 1, if an action is necessary, the interaction method can include a phase of selecting at least one application from the library stored on the server 11. This concerns in particular applications for the management of remedial exercises to be carried out by the user U to improve his physiological or emotional state, as a function of the datum defined representative of the physiological or emotional state of the user U. The choice of the application depends on the desired remedy.

[138] To do this, the interaction method can include a step of interrogating the server 11 to identify applications from the library suitable for remedying the physiological or emotional state of G user U. This can be implemented. by the processing unit 7, in particular the data communication module of the processing unit 7 with the server 11.

[139] The application selection process is based on the physiological / emotional state of user U as measured by measuring device 5 in motor vehicle 100.

[140] For example, if the physiological state of the user U corresponds to a stressed or nervous state, and / or if his emotional state corresponds to a state of rage or anger, a relaxation application can be selected. . Or, if the physiological state of the user U corresponds to a state of nervousness and / or if his emotional state corresponds to a state of fear, a meditation application can be selected. On the contrary, if the user demonstrates a calm physiological state and / or a neutral emotional state, a multiple choice exercise application for example may be selected. According to another example, if the user is in a calm physiological state and / or in an emotional state of the order of disgust, a learning application may be offered to him, for example in the event of a vision abnormality, an orthoptic application can be selected for an exercise in eye movements, or the like. Alternatively, if the user is in a calm physiological state and / or in an emotional state corresponding to joy, an application of a rehabilitation exercise may be selected. According to another example, if the physiological state corresponds to a sleeping state and / or if the emotional state corresponds to sadness, an application of a stimulation exercise can be selected. If the physiological state of the user U demonstrates fatigue and / or if the emotional state corresponds to a state of surprise, an application of a concentration exercise can be selected. According to yet another example, if a state of inattention is detected an application of attention exercises can be selected. [141] This selection can be made by a data processing module of the processing unit 7 of the interactive system 1.

[142] To this end, the mapping of the physiological or emotional state of the user U can be correlated with one or more mappings corresponding to different applications stored on the server 11. Among the different remedial exercise applications available in library, those allowing to bring the state of G user U to a neutral position can be selected. For example, in the case of a space for characterizing the emotional state of G user, such as a three-dimensional space A, V, D or in a two-dimensional variant A, V, the application (s) for which a representative datum is located symmetrically to the data representative of the emotional state of the user with respect to the neutral position in the characterization space, which can be three-dimensional A, V, D, can be selected, as shown schematically in figure 4. In this example purely by way of explanation, the data representative of the emotional state of the user at a given moment is for example located in position PI in the characterization space, which can be three-dimensional A, V, D. A application for which a representative datum is located in a position P2 symmetrical to the position PI with respect to the neutral position at the intersection of the axes A, V, D (or A, V in the case of a two-dimensional space), will tend to bring back the emotional state nnel of the user to this neutral position and will therefore be selected. The mapping of the applications can either be on the server 11 or be downloaded via the interactive system 1, for example on a storage space provided for this purpose in the processing unit 7.

[143] Referring again to Figures 1 and 2, after this selection of one or more applications, the interaction method includes a phase of notification to G user. This notification phase is used to inform the user, via interface 3 or one of the interfaces of the interactive system 1, about the application or applications selected automatically. At least one piece of information relating to a selected application can be notified to the user U, for example by display. This notification can be made by the processing unit 7 of the interactive system 1, for example the information module of the processing unit 7.

[144] The notification can also make it possible to inform the user U about his physiological or emotional state. [145] The user U can then validate the application notified to him or one of the applications if a list, possibly classified, is notified to him. This validation can be done by interaction with the interface 3, for example by pressing on a touch screen on board or not in the motor vehicle 100.

[146] The interaction process may include a step of detecting a user validation action. This detection can be carried out by the processing unit 7, for example an information module of the processing unit 7.

[147] There follows a phase of downloading from the server 11 of the application validated by the user U, for example by a download module of the processing unit 7. The validated application is downloaded to a storage space provided for this purpose of the processing unit 7.

[148] The interaction process also includes a remediation phase R (Figure 2).

[149] This R remediation phase includes running the downloaded application. The user can then perform at least one session of the remediation exercise.

[150] Referring to FIGS. 2 and 5, advantageously, the application takes place according to a predefined number of sequences from among an SI sequence of choice in an application menu, a relaxation or preparation sequence S2, a sequence S3 for performing the remediation exercise by the user, a sequence S4 for explaining the remediation exercise, a sequence S5 for feedback from G user on the remediation exercise performed. Preferably, the library remediation exercise applications are sequenced in a similar fashion. These different sequences SI to S5 are used to support G user during the execution of the application.

[151] The S2 sequence of relaxation or preparation is prior to the S3 sequence of performing the remediation exercise by the user. In fact, by relaxing the user before exercising, he can perform the exercise effectively. Such a relaxation or preparation sequence S2 can be of relative duration because it depends on the physiological or emotional state of the user. Indeed, there is no point in prolonging this S2 sequence of relaxation or preparation if the user is already in a relaxed state, for example.

[152] The sequence S4 for explaining the remedial exercise can be performed after the sequence S3 for performing the exercise. This sequence S4 makes it possible to explain to the user G the utility, the objective of the exercise, its importance and / or its therapeutic effect. During this explanatory sequence S4, the user can receive at least one piece of information concerning his performance, and / or his progress. The user can also receive at least one information concerning his physiological or emotional state during the exercise.

[153] According to an advantageous option, when the application is executed, the user can interact with at least one specialist or a team of specialists in the field concerned, depending on the downloaded application. This user interaction with the team can be done via the telephony and / or messaging and / or video telecommunication module. The user can for example ask questions, verbally or in writing, during a sequence S3 of carrying out the remedial exercise, or during a sequence S4 of explanation, and to have a response from this team of specialists, or again during an S5 experience feedback sequence. Like the user, the connected team can respond in writing or verbally.

[154] The information entered by the user during the last experience feedback sequence S5 can be stored on the vehicle's internal memory medium and / or on a storage medium external to the vehicle. This feedback information can be analyzed by at least one processing means of the interactive system 1 to improve the remediation exercise.

[155] At least some of these sequences are essential, in particular the S3 sequence of performing the remediation exercise by the user, and the SI sequence of choice in an application menu.

[156] Other S2, S4, S5 sequences may be optional. In particular, one or more of the relaxation sequences S2, S4 for explanation, S5 for experience feedback, can be omitted at the request of the user via interface 3. As a variant, certain sequences S2, S4, S5 cannot be not be offered to the user automatically by the interactive system 1.

[157] In addition, the sequences SI to S5 can be adapted specifically for the user. The adaptation of the sequences can be done according to the physiological or emotional state of the user during these SI - S5 sequences, as detailed below.

[158] The measurement phase M described above can take place during at least one of the sequences SI to S5 when the application is executed. [159] In order to allow a personalized analysis of the user's performance when carrying out the remediation exercise, the interaction process may include a performance study phase. This performance study phase is in particular implemented during a sequence S3 of carrying out the remediation exercise by G user.

[160] The performance study phase includes a step to collect user performance data during a remediation exercise session, when the application is running.

[161] This is followed by a step to determine, from the performance data recorded, whether the user has carried out the remediation exercise in accordance with the instructions of the application. The performance data can be compared to statistical or optimal data which can for example be accessible from the server 11 or be downloaded via the interactive system 1. Such statistical or optimal data is generally available when there is a follow-up by a monitor. practitioner.

[162] The performance study can be carried out by the processing unit, and in particular by the performance study module of the processing unit.

[163] As a variant or in addition, the interaction method may include a step to define the progress of G user compared to at least one previous performance. To do this, the method may include one or more steps of comparing the data recorded during different performances in order to produce progress statistics. In particular, it is possible to identify one or more aspects of the remedial exercise for which the performance of the user shows improvement, such as better concentration during the meditation exercise, or movement of the user. more precise part of the body, or whatever.

[164] A notification phase can be used to inform the user of this progress.

[165] Adaptation of the exercise

According to a second aspect, the interaction method makes it possible to adapt a remedial exercise chosen by the user U and / or proposed automatically by the interactive system 1 of FIG. 1, as a function of the physiological or emotional state of the user U. This second aspect comes as a variant or in addition to the first aspect of the interaction method described above. [166] According to this second aspect, in addition to the phases of measurement M, reception and interpretation I, and remediation R previously described with reference to FIGS. 1 to 5, the interaction method includes an analysis phase A. This analysis phase A can be implemented by the processing unit 7 of the interactive system 1, in particular by the analysis module of the processing unit 7.

[167] The analysis phase A makes it possible to potentially adjust the remedial exercise according to the physiological or emotional state of G user U when performing this exercise.

[168] To this end, the analysis phase A may include a step for comparing data representative of the physiological state of G user defined from parameters obtained by the measuring device 5 before and during the execution of the 'application. Analysis phase A includes a step to determine based on the comparison results whether an adjustment of the remediation exercise is necessary, and to potentially adjust at least one parameter of the remediation exercise.

[169] The analysis phase A can also take into account the performance data obtained by the measuring device 5, to potentially adjust the remedial exercise according to the previous and / or current performance of the user, or depending on its progress.

[170] Alternatively or in addition, the analysis phase A can also take into account data related to G use of the motor vehicle, such as navigation data, for example.

[171] The parameter can be adjusted during the remediation exercise during. As a variant or in addition, the parameter can be adjusted for a subsequent session of the remedial exercise.

[172] Before the start of the exercise, for example at the start of sequence S2 or S3, there may be an analysis of the performance of a previous session and an adaptation based on this performance analysis.

[173] The adjustment of the remedial exercise takes place by adjusting the duration, intensity, type of content, speed of a sequence S1, S2, S3, S4, S5 according to the physiological state of the user during the sequences S1, S2, S3, S4, S5. For example, one or more sequences can be of shortened duration, or be accelerated or slowed down for example. A change of type of sequence can be for example to change the music if the exercise is accompanied by music and the previous music has the effect, for example, of tensing the user.

[174] Also, depending on the physiological and / or emotional state of the user, at least one of the sequences, when not essential, may not be executed, deployed. The choice of sequences to be executed is therefore adjusted. For example, if the interactive system 1, in particular the processing unit 7, determines that G user U is tired, one or more of the optional sequences, such as the sequence S2 of relaxation, S4 of explanation, or S5 of return d experience, may not be performed.

[175] Notably, if the valence is too negative, the duration of one or more sequences may be reduced. On the contrary, if the valence is more positive, the duration of one or more sequences can be increased. Similarly, if the arousal is very positive, the duration of one or more sequences may be increased or even the intensity or difficulty of one or more sequences may be increased. Otherwise, if the arousal is very negative, the duration of one or more sequences and / or the intensity can be significantly reduced.

[176] For example, if the user's physiological state is in a zone corresponding to a sleeping state and / or if his emotional state reflects a state of rage or anger, the duration of one or more sequences may be decreased and the rhythm of these sequences can be adapted. For a stressed physiological state and / or a neutral emotional state, the duration can be stable and the rhythm adapted. If the user's physiological state corresponds to nervousness and / or if their emotional state corresponds to fear, the pace of the sequences may be reduced and the sequence of explanations may be longer. According to another example, if the physiological state of G user is in an area corresponding to a state of fatigue and / or if his emotional state is in an area corresponding to a state of disgust, the duration of one or more sequences may be diminished. On the contrary, if his physiological state corresponds to a calm state and / or if his emotional state reflects joy or sadness, the duration of one or more sequences may be lengthened. According to yet another example, if his physiological state corresponds to a calm state and / or if his emotional state corresponds to a state of surprise, the duration of one or more sequences can be lengthened and the rhythm of these sequences can be adapted.

[177] To facilitate understanding of the fit of the SI - S5 sequences, four examples, chosen arbitrarily, are shown in Figure 5. Each example corresponds to an adjustment of the remediation exercise for a respective user U1, U2, U3, U4.

[178] Thus, for the first example, concerning the user Ul, we see that the duration is shorter for example than for the user U2 of the second example. The total duration of all the sequences SI to S5 can be shortened by the interactive system 1, more precisely by the processing unit, for example after having determined as a function of the parameters obtained by the measuring device that the user Ul is tired. This shortened duration can also be a consequence of a very good previous performance of the user U1, or even because the interactive system 1 has detected that the user U1 is on a short trip, for example from data. of navigation collected in a known manner.

[179] In the second example, concerning the user U2, the sequence S3 for carrying out the remedial exercise may be of longer duration compared to the other sequences SI, S2, S4, S5. The duration of the sequence S3 of carrying out the remediation exercise can be lengthened by the processing unit, for example after having determined as a function of the parameters obtained by the measuring device that the user U2 has a need for remediation. more thoroughly, for example for a therapeutic exercise, or if the processing unit determines that the user U2 is in a state of great concentration or awake.

[180] In the third example, concerning user U3, the explanatory sequence S4 is omitted. This omission can be done, for example, if the processing unit determines, based on the parameters obtained by the measuring device, that the user U3 is tired, and / or that he has already done this exercise and knows the explanation.

[181] In the fourth example, concerning the user U4, the sequences S2 for relaxation and S5 for feedback. The omission of the relaxation sequences S2 can be done for example if the processing unit determines according to the parameters obtained by the measuring device that the user U4 is already in a relaxed state, relaxed enough to perform the exercise. of remediation and does not need more relaxation. The omission of the experience feedback sequence S5 can be done for example if the processing unit determines, as a function of the parameters obtained by the measuring device during a previous session, that the user's emotional state U4 is more negative during this S5 sequence, for example if the valence becomes negative, or if it is of no interest during this S5 sequence.

[182] Also, depending on the physiological or emotional state of the user, the interactive system may determine that the exercise chosen by the user is not relevant, for example because the user is not sufficiently energized. form to perform it, and automatically offer to stop the exercise or perform another exercise more suited to the physiological or emotional state of the user. The interactive system then offers a more appropriate alternative exercise or may also suggest postponing remediation.

[183] The interactive system can still check, using the parameters obtained by the measuring device, whether the user reaches the expected level of relaxation when performing the S2 relaxation sequence. If this level of relaxation is not reached, the interactive system can automatically suggest not to perform the exercise (sequence S3). Indeed, in such a case, the exercise may not be relevant to obtain the desired remedial effect.

[184] In addition, the interaction method advantageously makes it possible to identify whether or not the adjustments made to the sequences are beneficial for the user.

[185] For this purpose, the measurement phase M can be implemented before and after adjustment of the parameter (s) of the remediation exercise by at least one sensor of the measuring device 5 (see Figures 1 and 2). During the reception and interpretation phase I, data representative of the physiological or emotional state of user U is defined for the periods before and after the adjustment of the parameter (s) of the remedial exercise.

[186] During the analysis phase A, the data representative of the physiological or emotional state of the user U before and after adjustment of the parameter of the remedial exercise can be compared. Depending on the comparison results, the analysis module can determine whether the adjustment of the parameter (s) had a beneficial or on the contrary negative effect on the physiological or emotional state, for example by positioning the representative data in space. three-dimensional A, V, D, as described above. Thus, the interaction process does not aim at a one-off remedy, but seeks to tend at all times towards an optimal physiological, emotional state of user U for the remediation exercise to proceed correctly. This optimal state may vary over time.

[187] Adaptation of the multisensory environment

According to yet another aspect of the interaction process, the multisensory environment of the user U can be adapted according to his physiological or emotional state. This action on the multisensory environment can complement the remedial exercise. This allows the user U to gain a better insight into the remediation exercise.

[188] To this end, the mapping of the physiological or emotional state of user U can be correlated with one or more mappings corresponding to different stimuli, based on one or more of the five senses. By way of illustration, an example of mapping corresponding to the direction of the view is shown diagrammatically in FIG. 6.

[189] The mapping of the senses can be carried out in several stages E1, E2, E3, as illustrated in FIG. 7. For greater clarity, the mapping of a single direction, such as the view, is shown in FIG. 7. The initial mapping, in step E1, corresponds to a primary emotional state of the user, that is to say an emotional state in which the user reacts in a primary manner. The mapping is then modified taking into account the impact of the user's culture and / or education, this is step E2. We notice in the arbitrary example of Figure 7, that the colors red R and blue B are closer to neutrality along the A axis of the arousal, compared to the initial mapping (El). The last step E3 in building the map concerns the impact on personal life and / or user experience. We notice in the arbitrary example of Figure 7, that the blue color B approaches the positive side along the axis of valence V and dominance D.

[190] The interaction process, and in particular the remediation phase R, can include an action step during which at least one multisensory stimulus is applied so as to modify the physiological or emotional state of G user U (figures 1 and 2). The choice of stimulus or stimuli depends on the desired effect. After placing the data representative of the emotional state of G user U on the map, different types of actions can be selected.

[191] For example, a stimulus located symmetrically with respect to the neutral position in the space characterizing the emotional state of the user U, such as the space three-dimensional A, V, D can be applied. In this way, the user's emotional state can tend towards the neutral position.

[192] We can also consider applying a stimulus positioned in the direction opposite to the neutral position in the characterization space of the emotional state of the user U, such as the three-dimensional space A, V, D ( relative to the initial position); so as to amplify an emotion for example.

[193] It is also possible to provide for the application of a stimulus making it possible to pass from the initial position (initial status of the emotional state) to a specific given position (desired status of the emotional state), the stimuli (s) being chosen in depending on the specific position given.

[194] More precisely, the action step for the application of a stimulus, is a step of controlling at least one actuator in the motor vehicle so as to activate the multisensory stimulus. This stimulus can be applied during at least one sequence of the remedial exercise.

[195] The method may include an information step in which the user is informed of the stimulus or stimuli applied.

[196] With a view to always being better suited to the user U, the measurement phase M of at least one parameter linked to the user G can be implemented before the action step and when the stimulus interacts with the user U by at least one sensor of the measuring device 5. From these parameters, data representative of the physiological state of the user before and during the action step can be defined during the interpretation phase I, for example by the interpretation module of the processing unit 7.

[197] During analysis phase A, data representative of the physiological or emotional state of user U before and after application of the stimulus can be compared. Depending on the comparison results, the analysis module can determine whether the application of the stimulus had a beneficial or on the contrary negative effect on the physiological or emotional state, for example by positioning the representative data in the three-dimensional space A , V, D, as previously described.

[198] One or more phases of the interaction process according to one or other of the aspects described above, in particular from the phases of measurement M, interpretation I, remediation R, and analysis A, can be implemented on an ongoing basis. In addition, these phases M, I, R, A implemented continuously are also implemented in parallel to the execution of one or more of the sequences S1 to S5 as described above.

[199] It is therefore understood that the interaction method implemented at least partially by the interactive system 1 as described above can make it possible to automatically offer one or more applications from a library stored on a remote server 11.

These applications relate to remedial exercises which correspond to the physiological or emotional state of the user U, defined from measurements carried out in the motor vehicle 100 and by an interpretation of these measurements using an evaluation model of the physiological or emotional state of G user U. [200] The interactive system 1 also makes it possible to manage and supervise remedial exercises carried out according to different sequences SI to S5, and to adapt the sequences Sl- S5 according to the physiological state or emotional user U during remediation exercises. The remedial exercise is thus specifically adapted for the user U, which makes it possible to tend towards an optimal physiological (or emotional) state when G user performs the remedial exercise.

[201] Finally, the multisensory environment of G user U can be improved by applying one or more stimuli in order to promote a better perception of the remedial exercises by G user U.
