Description

Method and device for managing a message intended for at least one terminal of a user.

The present invention relates to a method for managing a message intended for at least one terminal of a user.

It also relates to a management device implementing the proposed management method.

The invention applies in particular to any equipment, terminal or object configured to receive messages and present them to a user.

User terminals, such as mobile phones, connected watches or others, nowadays receive many notifications, whether textual notifications such as electronic mails (emails or emails in Anglo-Saxon terminology), SMS type messages (Short Message Service) or notifications intended for applications (e.g. journalistic applications), or notifications of telephone calls.

The receipt of these notifications by the user can modify the emotional state of the users, both because of the content of the notification and the number of notifications received. In addition, the emotional state of the user when receiving a notification (current emotional state) can influence the perception of a notification.

Thus, sometimes, the user receiving a notification that acts on his emotional state, may not consider it and even acquire a negative perception of the source of the notification or of a service offered by the notification.

On other occasions, due to a particular emotional state of the user, an important or urgent notification may go unnoticed by the user, or its importance or urgency may not be taken into account by the user.

Solutions exist to control the delivery of messages to users based on user preferences, the preferences being prefixed by the users. Very often, the user sets preferences in order not to be disturbed or interrupted at certain times, or at least to reduce interruptions. For example, a preference can provide that the delivery of a notification is delayed if when it is received by the terminal or the message management center, the user is busy, for example in a meeting.

Nevertheless, although the delivery of the notifications takes into account the preferences of the user, they can be delivered at times which are not favorable for the user or in contexts which are not favorable to the consideration of the message by the user. For example, the user may feel stressed and not receptive to notifications, while in his agenda no meeting is scheduled.

The present invention aims to improve this situation and proposes a method for managing notifications intended for a user's terminal making it possible to deliver notifications at the most convenient time for the user.

To this end, the invention relates, according to a first aspect, to a method for managing a message intended for at least one terminal of a user.

According to the invention, the management method comprises the following steps implemented by a management device:

- obtain physiological data representative of an emotional state of the user,

- determining at least one action relating to the delivery of said message on at least said terminal, according to said physiological data obtained, and

- implement said at least one specific action.

Thus, thanks to the management method, the delivery of a message intended for at least one terminal of the user is conditioned by the emotional state of the user. In other words, the delivery of the message is modified in such a way as to adapt it to the emotional state of the user.

It should be noted that the purpose of delivering a message is to present the message to the user of the terminal. Thus, delivery of a message on the terminal means the presentation of the message on the terminal, via a user interface.

Determining an action relating to delivery of the message may include, depending on the emotional state of the user, determining presentation of the message (or determining that the message will be presented), refusal of presentation (or determining that the message will not will not be presented), the shift in the time of presentation of the message, the delivery of the message at a determined time, the modification of the content of the message to be presented, the form of delivery of the message, for example if the message is accompanied by a ring tone, by a vibration or by neither of the last two, etc. In all cases, the delivery of the message takes into account the emotional state of the user, making it possible to deliver the message at the optimal moment in relation to the emotional state of the user.

For example, actions can be:

- delivering the message to at least one user terminal. The message can be delivered to several terminals that can be associated with said at least one user terminal,

- associate the message with a subsequent delivery time,

- modify at least part of the content of the message, for example the subject of a message, etc.

For example, with the proposed method, if the user finds himself nervous, it can be determined to shift the presentation of the message, thus avoiding that the message can be put aside by the user or that the user can become even more nervous.

The message may be intended for a terminal (a first terminal) or several terminals of the user (including the first terminal). For example, the user can have several terminals receiving the message, these terminals being able to be associated with each other. For example, a user can have a mobile terminal and an electronic watch or bracelet associated with or coupled to the mobile terminal. Thus, the mobile terminal and the watch or the electronic bracelet can receive the notifications or messages. In this case, the messages are intended for the mobile terminal and the user's watch.

The physiological data representative of an emotional state of the user can be obtained by a biometric module present in the terminal of the user for which the message is intended, or from a biometric module present in another electronic device such as another associated user terminal. For example, in the case of a user having a mobile terminal and a connected watch associated with the mobile terminal, the physiological data can be obtained by a biometric module present in the connected watch. The biometric module is configured to measure physiological data of the user, these data being representative of the emotional state of the user. It will be noted that the message may be intended for the mobile terminal and/or the connected watch.

The management device implementing the management method can be integrated into a terminal of the user, which can be the terminal for which the messages are intended or can be different from this terminal. Furthermore, the management device can be integrated into a server, for example a messaging server. In addition, the management device can be distributed among several of the aforementioned entities.

According to one characteristic, the physiological data obtained includes data relating to the electrical activity of the user's heart.

Data of a user's heart activity gives a good indication of the user's emotional state.

According to one characteristic, the management method further comprises the determination of the emotional state of the user according to the physiological data obtained, the emotional state being represented by a set of parameters.

Thus, the method includes the determination of a set of parameters representative of the emotional state of the user. This determined set of parameters represents the emotional state of the user.

The value of the parameters of the set is determined according to the physiological data obtained.

For example, the parameters of the set can be valence, arousal or arousal (known in Anglo-Saxon terminology as arousal) and dominance. Valence defines the power of attraction (positive valence) or repulsion (negative valence) that the user feels towards a situation or an object. Arousal or excitation gives a physiological activation order (e.g. weak arousal or strong arousal). Dominance indicates the degree of control the person has over the emotion felt. In the rest of this document, we take as an example the use of valence and arousal, without being limiting. In addition, the set of parameters may include other parameters representative of the emotional state of the user.

Known methods make it possible to give values to these parameters (valence, arousal and/or dominance for example) according to physiological data of the user, in particular according to data relating to the electrical activity of the heart of the user. Thus, depending on the values of the parameters, the emotional state of the user can be determined.

According to one embodiment, the determination of the emotional state is implemented by an artificial intelligence algorithm.

Thus, the determination of the values of the set of parameters such as valence and arousal, is implemented by means of an artificial intelligence algorithm.

This artificial intelligence algorithm includes a phase of learning a neural network and a phase of using the neural network to determine the values of the parameters representative of the emotional state of the user.

According to one characteristic, the determination of at least one action comprises the comparison of the value of the parameters of the set of parameters with threshold values respectively, said at least one action being determined according to the result of said comparison.

Thus, by comparing the value of parameters such as valence or arousal with predefined thresholds, an action relating to the delivery of the message is determined. For example, it can be estimated, depending on the emotional state of the user, whether the delivery should be implemented or how the delivery of the message should be implemented.

In one embodiment, actions are respectively associated with the possible results of the comparison. For example, if the values of valence and arousal are above the respective thresholds, a first action is determined, if the value of valence is above the valence threshold and the value of arousal is below the threshold d awakening, a second action is determined, etc.

It will be noted that several comparisons with several thresholds can be implemented for the same parameter. For example, the value of a parameter can be compared with a lower threshold and with an upper threshold, to determine whether the parameter value is inside or outside a range of values.

According to one characteristic, said at least one action is further determined according to a set of rules predefined by the user.

Thus, the determination of said at least one action takes into account, in addition to the emotional state of the user, preferences predefined by the user.

Message delivery rules are well-known and widely used today, and correspond to any rule established by the user that impacts message delivery. For example, these rules may establish times for the delivery of messages or times when the delivery of messages must be avoided, the delivery of all messages from a sender or, on the contrary, the non-delivery of messages from a transmitter, etc.

According to one embodiment, obtaining data is implemented upon receipt of said message by the terminal or by a server managing the reception of messages from said terminal.

Thus, obtaining data representing the emotional state of the user is implemented each time a message intended for the user is received. The emotional state of the user is therefore taken into account in real time for the implementation of the delivery of a message.

According to embodiments, the physiological data is obtained following the reception of a message by the terminal for which the message is intended or following the reception of the message by the messaging server associated with the terminal for which the message is destined.

According to another embodiment, obtaining data is implemented periodically.

According to this embodiment, the emotional state of the user is determined regularly and independently of the reception of the messages. Thus, when receiving a message, the action to be implemented on the message is determined more quickly. This embodiment is more efficient when the physiological data is obtained frequently, i.e., the period of obtaining the data is short. This makes it possible to take into account changes in the emotional state of the user.

The characteristics of the management method presented below can be taken alone or in combination with each other.

The present invention relates, according to a second aspect, to a device for managing a message intended for at least one terminal of a user, comprising:

- a module for obtaining configured to obtain physiological data representative of an emotional state of the user,

- a determination module configured to determine at least one action relating to the delivery of said message to at least said terminal, as a function of said physiological data obtained, and

- an action module configured to implement said at least one determined action.

According to one characteristic, the obtaining module is configured to obtain said physiological data from at least one sensor associated with said user terminal.

For example, said at least one sensor can be located in the user terminal or in an electronic device associated with the user terminal. This electronic device can be a second terminal of the user.

The management device can be integrated in the terminal of the user for which the message is intended, in another terminal of the user associated with the terminal of the user for whom the message is terminal or in a server receiving the messages intended for at least the user's terminal.

The present invention relates, according to a third aspect, to a user terminal comprising a management device according to the invention, and a user interface for presenting messages.

The present invention relates, according to a fourth aspect, to a system comprising at least two user terminals associated with each other, at least one of the user terminals being in accordance with the invention.

The present invention relates, according to a fifth aspect, to a program for a management device, comprising program code instructions intended to control the execution of the steps of the management method in accordance with the invention.

The present invention relates, according to a sixth aspect, to an information medium readable by a processor in a management device, on which the computer program in accordance with the invention is recorded.

The management device, the user terminal, the system, the computer program and the information medium have characteristics and advantages similar to those described above in relation to the management method.

Other features and advantages of the invention will appear further in the description below.

In the accompanying drawings, given by way of non-limiting examples:

- there represents an example of a context in which the management method can be implemented,

- there illustrates steps of the management method in accordance with one embodiment of the invention,

- there illustrates steps of a management method in accordance with a second embodiment of the invention,

- there illustrates a hardware architecture that can implement the management method according to the invention; And

- there is a functional representation of a management device according to one embodiment of the invention.

The invention applies to any terminal of a user receiving written and voice messages via a communications network.

There illustrates an example of the context in which the management method can be implemented. In the illustrated context, a user 1 has several terminals 2, 3 able to receive messages or notifications. Note that the terms message and notification are used interchangeably in this document.

By user's terminal is meant an electronic device allowing the user to receive data via a communication network 4. In other words, the user's terminal is an access point making it possible to connect to a wired or radio communication network and making it possible to receive and decode the messages received via this network. The user's terminal is the recipient of a message, this message being intended for the user. In this document, a message intended for the user and a message intended for the user's terminal are equivalent.

In the example illustrated, the user terminals correspond to a connected watch 2 and a mobile terminal 3 configured to receive messages intended for the user. For example, the connected watch 2 can be associated with the mobile terminal 3. Thus, the connected watch 2 can be configured to receive the messages received by the mobile terminal 3. The terminals are considered to be associated with the user. Of course, this example is not limiting, the invention applying to any type of terminal configured to receive messages. For example, the user's terminal can be a tablet, a personal computer, a game console, a fixed telephone terminal, etc.

An embodiment of a user terminal that can implement the proposed management method will be described with reference to Figures 4a and 4b.

The messages received by a user's terminal can be of different types, for example text messages, such as electronic messages (e-mail), short text messages or SMS-type messages, messages received via instant messaging, phone call notifications, notifications relating to applications installed in the terminal, etc. In general, the user's terminal is configured to receive different types of messages via the communication network. For example, the terminal may include several applications managing the reception and transmission of messages. For example, the terminal can include an instant messaging application, an application managing the SMS-type messaging service, an application managing telephone calls, journalistic or other applications receiving information, alert, advertising notifications, etc. .

The messages received in the terminals of the user 2, 3 can come from another terminal 30 of a user 10 or from a notification server 5 configured to send notifications to the user terminals, for example log notifications.

The management method (described with reference to FIGS. 2 and 3) of a message intended for at least one user terminal 2, 3 is implemented by a management device 300. According to embodiments, the management 300 can be integrated in a terminal of the user 2, 3, in a server 6 managing the messages received by the user terminal such as a messaging server, or distributed between one or more terminals of the user 2 , 3, or between one or more user terminals 2, 3 and a server 6.

There illustrates steps of the method for managing a message intended for a user terminal according to one embodiment.

In one embodiment, the management method is implemented by one of the user's terminals, for example by the connected watch 2. It is thus considered that the management device 300 is integrated in the connected watch 2. In this description, the management device 300 is confused with the connected watch 2. Thus, it is considered that the connected watch 2 implements the steps of the management method.

According to other embodiments, the steps of the method can be implemented by another terminal such as the mobile terminal 3, or by a server 6 such as a messaging server. According to another embodiment, steps of the method can be implemented by different terminals respectively and/or by the server.

As will be described below, thanks to the management method, the delivery of messages to a user terminal 2, 3 takes into account the emotional state of the user 1. The management device in the watch connected 2 is configured to manage the messages intended for the connected watch 2 itself and/or for the mobile terminal 3. Of course, the messages can be intended for other terminals of the user.

According to embodiments, the messages intended for the connected watch 2 can be received by the connected watch 2 before the implementation of the management method (for example, when the management method is implemented by the connected watch, at namely the embodiment described), or can remain in a server 6 of the electronic messaging server type before the implementation of the management method (for example when the management method is implemented by the server).

It is considered for the description of the management method below, that the messages are intended for at least the connected watch 2 and that the messages are received by the connected watch 2 before the implementation of the management method. In one embodiment, the receipt of an electronic message triggers the implementation of the proposed management method.

When a message is received by a user terminal (the connected watch 2) during a reception step E0, the user terminal 2 obtains E1 physiological data (or biometric data) 100 representative of a emotional state of user 1.

In one embodiment, the physiological data 100 comprises data relating to the electrical activity of the heart of the user 1.

The data of the electrical activity of the heart or cardiac activity of a user gives a good indication of the emotional state of the user.

This data relating to the cardiac activity of the user can be obtained from at least one electrocardiogram or similar sensor.

In the embodiment described, the connected watch 2 includes at least one ECG electrocardiogram sensor ( ) configured to obtain data 100 relating to the electrical activity of the heart of the user 1. Thus, in the embodiment described, the data 100 relating to the electrical activity of the heart of the user 1 are obtained by said at least one ECG electrocardiogram sensor embedded in the connected watch 2.

In other embodiments, physiological data 100 may be obtained from another electronic device. For example, if the management method is implemented by the mobile terminal 3, the physiological data 100 can be obtained from the connected watch 2 associated with the mobile terminal 3, this watch comprising at least one ECG electrocardiogram sensor configured to obtain, in turn, the data 100 relating to the electrical activity of the heart of the user 1.

It will be noted that when the user terminal does not include the means necessary for obtaining physiological data 100 by itself, it is configured to obtain them from another electronic device associated with the user terminal.

According to embodiments, the electronic device measuring the cardiac activity of the user 1 can be a terminal, such as the connected watch 3 or a connected bracelet, or any other electronic device comprising electrocardiogram sensors configured to measure and record the electrical activity of the user's heart, such as a cardiac holter type device.

As indicated above, in the embodiment described, the obtaining E1 of data is implemented upon receipt E0 of a message by the user terminal (the connected watch).

The physiological data 100 are thus obtained in real time and the emotional state determined is the current emotional state, that is to say at the time of reception of the message.

In the embodiment described, once the connected watch 2 has obtained the physiological data 100, it implements the determination E2 of the emotional state of the user according to the physiological data 100 obtained.

In one embodiment, the emotional state is represented by a set of parameters representative of the emotional state. For example, the set of parameters includes user valence and user arousal or arousal. It is known that these two parameters represent the emotional state of the user. The valence VAL is representative of the power of attraction or repulsion that the user feels with regard to a situation or object. ARO arousal (arousal in Anglo-Saxon terminology) is representative of physiological activation corresponding to an emotion.

Depending on the 200 physiological data obtained E1, a value is given to the parameters, this value indicating numerically the power of attraction or repulsion, in the case of the valence, and the intensity of physiological activation in the case of the awakening. By way of non-limiting example, a value from 1 to 10 can be given to each of the parameters. For example, in the case of valence, the value 0 is indicative of the maximum power of repulsion or minimum attraction, and the value 10 is indicative of the power of minimum repulsion or maximum attraction. Other scales of values, more or less precise, can be used. As another example, valence can be defined as positive or negative, and arousal as high (high) or low (low).

In one embodiment, the E2 determination of the emotional state is implemented by an artificial intelligence algorithm. Thus, the values of valence VAL and arousal ARO are determined by an artificial intelligence algorithm. An artificial intelligence algorithm can be based on a learning model (deep learning model in English terminology) using a neural network, for example of the Transformer type. This type of artificial intelligence algorithm is known and is not described here in detail. For example, the documents “Attention is All You Need. A. Vaswani, N. Shazeer, N. Parmar, J. Uszkoreit, L. Jones, A.N. Gomez, L. Kaiser, I. Polosukhin. In Advances in neural information processing systems, 2017” and “BERT: pre-training of deep bidirectional transformers for language understanding. J. Devlin, M. Chang, K. Lee, K. Toutanova. In Conference of the North American chapter of the association for computational linguistics: human language technologies, 2019” describe Transformer-like neural networks and uses of such neural networks.

In one embodiment, the physiological data obtained E1 comprise data sequences. These data sequences are processed E21 by a processing module before supplying them to the neural network for determining the emotional state of the user 1. In one embodiment, the data sequences can be segmented to form vectors data v1. By way of non-limiting example, the data is segmented by 10 ms windows.

In one embodiment, the data vectors v1 can be provided E22 to a neural network, for example a convolutional neural network (CNN for “Convolutional Neural Network”), to obtain second data vectors v2. These second data vectors v2 correspond to feature vectors describing the sequences of values in the data vectors v1. The term “feature vectors” is understood to mean a vector of numerical values in a vector space whose dimensions are characteristics making it possible to discriminate between different situations, namely the emotional states.

It will be noted that in the embodiment described, these feature vectors are generated automatically by learning with the convolutional neural network CNN.

Then, the second data vectors v2 are provided E23 to a second neural network to obtain values for the set of parameters VAL, ARO representative of the emotional state of the user 1. In one embodiment, the network of neurons comprises a first section of the Transformer type and a second section, attached to the first, of layers of “fully-connected” type neurons.

According to one embodiment, this second neural network is learned beforehand from data in a database DB_D containing numerous sequences of data representative of the electrical activity of the heart of user 1 (ECG type data) and associated VAL and ARO values. According to one embodiment, the learning of the neural network comprises a first phase during which the Transformer-type neural network learns to reconstruct, from the feature vectors (second vectors v2), input sequence vectors ( sequences with ECG data) with missing data. A second phase uses for each input sequence comprising ECG data the learning of the values VAL, ARO representative of the emotional state of the user 1 to be provided as output.

Once the values of the parameters of the set have been determined, each value of a parameter VAL, ARO is compared E31 with a threshold value respectively (threshold valence value and threshold arousal value).

In one embodiment, these comparisons make it possible to classify E32 the emotion in a category.

In one embodiment, the emotions are classified into four categories of emotions according to the result of the comparisons of the values of the parameters VAL, ARO with the threshold values respectively. These categories are as follows, determined based on the results of the comparisons:

- negative/weak when the valence is negative compared to the threshold valence value and the arousal value is lower than the threshold arousal value,

- negative/strong when the valence is negative with respect to the threshold valence value and the arousal value is greater than the threshold arousal value,

- positive/weak when the valence is positive with respect to the threshold valence value and the arousal value is lower than the threshold arousal value,

- positive/strong when the valence is positive with respect to the threshold valence value and the arousal value is greater than the threshold arousal value.

In the example scale of values shown below, the threshold value (for valence and arousal) can be 5.

Of course, other parameters can be used to represent the emotional state of the user. Also, the classification may include different categories of emotion. Additionally, multiple threshold values can be used to determine the value of a parameter.

Then, in the embodiment described, an action relating to the delivery of said message on at least said terminal is determined E33 according to the category of emotion obtained.

In one embodiment, at least one action relating to the delivery of a message is associated with each category of emotion. A database, called DB_E action database, lists the actions to be implemented for each category of emotion. Thus, once the emotion category is obtained, the action can be determined by consulting this database. This database is updated over time.

In one embodiment, the determination of the action also takes into account a set of rules predefined by the user. These user rules or user preferences are recorded in a database called DB_P preference database. This preference database lists actions relating to the delivery desired by the user, independently of the actions determined according to the emotional state of the user. By way of non-limiting example, an action may be to postpone the delivery of messages received during a time slot, to only deliver messages from a particular sender, not to deliver a type of notification, etc.

In one embodiment, the database of emotions DB_E is consulted first, and once the action to be implemented has been determined, the preference database DB_P is consulted to check whether a rule must be taken into account. The definition and application of user rules and preferences are known and will not be described here in detail.

In one embodiment, the content of the message intended for the user is taken into account. An index indicative of the positive character (if the message can influence the emotional state of the user positively) or negative (if the message can influence the emotional state of the user negatively) of the content of the message can be associated with the message. According to embodiments, this index can be sent with the message by the sender of the message or notification.

In one embodiment, the sender of the message or notification can associate an index with the message, this index being indicative of the positive character (if the message can positively influence the emotional state of the user) or negative (if the message can influence the emotional state of the user negatively) of the content of the message. According to another embodiment, the terminal receiving the message is configured to implement a semantic and/or syntactic analysis to recognize terms or expressions in the message and associate a positive index with the message, if the term or expression can influence the emotional state of the user positively, or negative if the term or expression can influence the emotional state of the user negatively.

By way of non-limiting example, if the emotion category is negative/strong and/or if the index associated with the message is negative (indicating that the content of the message may have a negative impact on the emotional state of the user), an action relating to the delivery of a message may be to postpone the delivery of the message to a later time. In another example, if the emotion category is negative/strong and the index associated with the message is positive (indicating that the content of the message can have a positive impact on the emotional state of the user), the action relating to the delivery of the message may be to deliver the message to the user.

In another example, if the emotion category is negative/strong, the information to be notified (message content) has a negative index, and the user's preference is to delay notifications, the message handler waits that a period of time elapses, for example 5 minutes, to again determine the emotional state of the user and to determine the action to be implemented relating to the delivery of the message. If, for example, the user's preference indicates when notifications can be received, the message handler waits for that time to re-determine the user's emotional state and determine the action to take. work relating to the delivery of the message.

Of course, these examples are given by way of non-limiting illustration.

Once the action to be implemented on the message is determined, it is implemented E4.

Examples of action relating to the delivery of the message can be the presentation of the message, the refusal of the presentation of the message, the delay of the instant of presentation of the message, the delivery of the message at a determined instant, the modification of the content the message to be presented (for example, shorten it if it is very long or modify its subject or title), the form of delivery of the message, for example whether the message is accompanied by a ringtone, by a vibration or by neither of the last two , etc.

According to embodiments, the steps can be implemented in different orders. There illustrates steps of the message management method according to another embodiment. In this embodiment, the steps are similar but implemented in a different order than in the embodiment described with reference to .

In this embodiment, obtaining data is performed periodically. The physiological data 100 obtained E1' are stored in memory. When a message is received E0', the determination of the emotional state E2 of the user is implemented using the recorded physiological data. The steps being similar to the steps described with reference to the , will not be described here again.

According to this embodiment, the emotional state of the user being determined regularly, the action to be implemented on the message is determined more quickly. It should be noted that the more frequently the physiological data are obtained, the closer the physiological data obtained are to the instant of reception of the message.

According to another embodiment not illustrated, the obtaining and the determination of the emotional state of the user are implemented regularly, the data and/or the emotional state are recorded in memory. In this embodiment, when a message is received by the terminal (or the messaging server), the recorded emotional state is used to determine the action to be implemented on the message. In this embodiment, the processing of the message is faster.

There schematically illustrates a hardware architecture of a user's terminal comprising a management device capable of implementing the proposed management method, and more particularly of a terminal comprising a management device capable of implementing the method.

The management device 200 or the user terminal 2, 3 comprises a communication bus 200 to which are connected:

- A processing unit 201, named in the figure CPU (for "Central Processing Unit") and may include one or more processors;

a non-volatile memory 202, for example ROM (for “Read Only Memory”), EEPROM (for “Electrically Erasable Read Only Memory”) or a Flash memory;

- A random access memory 203 or RAM (for "Random Access Memory");

- an input/output interface 204, named in the figure I/O (for “Input/Output”), for example keys or buttons, a screen, a keyboard, a mouse or another pointing device such as a touch screen or a remote control enabling a user to interact with the user's terminal via a graphical interface or man-machine interface; And

- a communication interface 205, named COM in the figure, suitable for exchanging data for example with other user terminals or other associated electronic devices, or with a server 5, 6, for example a messaging server 6 , via a communications network 4.

Random access memory 203 includes registers suitable for recording variables and parameters created and modified during the execution of a computer program comprising instructions for the implementation of the proposed management method. The program instruction codes stored in non-volatile memory 202 are loaded into RAM memory 203 in order to be executed by the processing unit CPU 201.

The computer program PG can implement artificial intelligence to determine the emotional state of the user based on physiological data. The implementation of artificial intelligence can be based, for example, on data from a knowledge base listing, for example, emotional states previously determined according to previous physiological data.

The non-volatile memory 202 is for example a rewritable memory of the EEPROM or Flash memory type which can constitute a support within the meaning of the invention, that is to say which can comprise a computer program PG comprising instructions for the implementation of the proposed management process. The rewritable memory can comprise for example the base database DB_D containing sequences of data representative of the electrical activity of the user's heart used by the artificial intelligence algorithm, the database of emotions DB_E listing the actions to be implemented for each category of emotion, the preference database DB_P listing actions relating to the delivery desired by the user.

In another embodiment, the databases can be external to the user's terminal.

These databases can be updated as messages are received, physiological data is obtained, and emotional states and actions are determined.

In one embodiment, the user's terminal includes at least one ECG electrocardiogram sensor configured to measure the electrical activity of the user's heart. In this embodiment, the user's terminal can be a connected watch or a connected bracelet.

In one embodiment, the ECG electrocardiogram sensor may be external to management device 300.

The PG program defines, by means of its instructions, functional modules of the user's terminal which are implemented and/or control the hardware elements described above. There is a functional representation of a terminal of a user able to implement the method and more particularly a terminal comprising a management device able to implement the method according to one embodiment.

These modules may include:

- a module for obtaining 21 configured to obtain physiological data representative of an emotional state of the user,

- a determination module 22 configured to determine at least one action relating to the delivery of said message to at least said terminal, as a function of said physiological data obtained, and

- an action module 23 configured to implement the determined action.

In one embodiment, the obtaining module 21 is configured to measure data relating to the electrical activity of the user's heart.
