Description

Description Title of the invention: Method for alerting a remote communication terminal and associated alert communication device Technical Field

[0001] The present invention belongs to the general field of communication, and more specifically to remote assistance. It relates more particularly to a method for alerting a remote communication terminal. It also relates to a communication device for alerting a remote communication terminal configured to implement such a method. Prior art

[0002] Currently deployed telecare systems consist of a box installed in a person's home and coupled with a radio transmitter in the form of a medallion or bracelet that must be worn by the person at all times. In the event of a fall or any other emergency, the person presses a button on the radio transmitter to initiate an emergency call. Pressing the emergency button generates the sending of a radio signal (e.g., Wi-Fi, Bluetooth) to the box, which in turn triggers a call to a telecare call center.

[0003] The person can then communicate with a call center operator using the unit's microphone and speaker to explain the reason for the call. If the operator believes the person is in an emergency situation, they immediately alert the person's loved ones, or possibly even emergency services, so that they can come to the person's home.

[0004] Another remote assistance solution is a connected bracelet that includes a SIM card. This connected bracelet is configured to geolocate the person, measure blood pressure and / or heart rate, and manually alert a contact of danger or a fall using an emergency button.

[0005] There are also solutions to ensure the protection and safety of lone workers. These devices, sometimes called "lone worker alarms," ​​can be triggered when specific situations, such as loss of verticality or lack of movement, are detected by the device. In this case, a call to a call center is then made.

[0006] However, such solutions do not offer the possibility of transmitting data to the call center interlocutor without the latter having to use an interpreter, i.e. without the interlocutor having to use a computer tool configured to analyze and translate data written in a language computer and transmitted by one of the teleassistance devices previously mentioned to the call center. Statement of the invention

[0007] The present invention aims to remedy all or part of the drawbacks of the prior art, in particular those set out above, by proposing a solution which, in response to the detection of an alert situation, makes it possible to communicate with the contact at a call centre, and in particular to inform them of the context of the call and, where appropriate, of the development of the situation. To this end, and according to a first aspect, the invention relates to an alert of a remote communication terminal, the method being implemented by an alert communication device (100) and comprising: - establishing a communication session between said alert communication device and a remote communication terminal triggered by detection of an alert situation; and, - a transmission, via the established communication session, of a generated message.

[0008] By message is meant not a compilation / aggregation of raw data generally obtained in machine language(s) but a message readable by a human, in particular a message in natural language, or another writing process readable by a human such as shorthand.

[0009] Thus, the alert communication device is capable of communicating in natural language with a contact on a remote communication terminal, such as a relative via their mobile telephone, a contact on an alert service, or even an emergency service, etc. This proves to be particularly advantageous when an individual in an alert situation is unable to communicate with this contact, in particular when the individual is unconscious or having a coughing fit, choking, etc.

[0010] Furthermore, the opening of a communication session by the alert communication device allows an exchange between the interlocutor of the remote communication terminal, in particular for the interlocutor to request additional information and / or to ask questions to the alert communication device which can always respond in the same communication session.

[0011] Generally speaking, it is considered that the steps of a process should not be interpreted as being linked to a notion of temporal succession.

[0012] In particular modes of implementation, the alert method may further comprise one or more of the following characteristics, taken individually or in all technically possible combinations.

[0013] In particular implementation modes, the establishment of the communication session is triggered by the detection of an alert situation based on data obtained from at least one sensor.

[0014] Thus, based on data obtained from at least one sensor, an alert situation is detected and it is this detection of an alert situation that triggers the establishment of the communication session. The communication session is therefore established when an alert situation is detected, in particular by means of data obtained from connected objects present in an environment and / or on an individual.

[0015] In particular modes of implementation, the transmission emits a message generated based on the detected alert situation and data obtained from at least one sensor.

[0016] Thus, the message transmitted via the communication session is not a simple notification of the alert situation but includes data obtained from connected objects present in an environment and / or on an individual allowing the user of the remote communication terminal and / or a remote decision-making device to make decisions relating to the alert situation, in particular in terms of deployment of emergency services, access to the environment and / or the individual in the alert situation, etc. It should be noted that the message generated is a function of data obtained which may either include all or part of the data obtained on the basis of which the alert situation is detected, or be distinct from the data obtained on the basis of which the alert situation is detected.

[0017] In particular embodiments, the transmitted message is a voice message generated by voice synthesis based on data obtained from at least one sensor.

[0018] In particular embodiments, the method further comprises: - obtaining data from at least one sensor, the data obtained being at least one of the following data: - data relating to a first individual; - data relating to an environment; - data relating to the environment of a first individual; - data captured by at least one sensor connected to the alert communication device; - data captured by at least one sensor of the alert communication device; - sound data comprising at least one sound signal captured by at least one sensor connected to the alert communication device; - sound data comprising at least one sound signal captured by at least one sensor of the alert communication device.

[0021] These sound data are for example: - an instruction from the first individual to establish communication; - sound data enabling the determination of the inability of the first individual to establish communication and / or even to communicate, such as a cough, a rattle, a choking, etc. - environmental sound data to determine an emergency situation, such as a crash, crackling, etc., whether or not a first individual is present.

[0022] In particular embodiments, the method further comprises calculating a value representative of a probability that the individual is unable to contact an emergency service, the establishment of a communication session being implemented if said value is greater than a threshold value.

[0023] In particular embodiments, the method further comprises determining the remote communication terminal based on the detected alert situation.

[0024] In particular embodiments, the method further comprises: - generation of an alert message, called the first message, based on at least one item of data from at least the following data: - at least one piece of data obtained; - at least one data item provided by analysis of data obtained from at least one sensor, and the alert message is capable of being voice synthesized and transmitted, upon establishment of the communication session, in the form of a voice message via the established communication session.

[0026] The at least one data and at least one data provided by analysis of data obtained are advantageous since they allow: - to determine that the first individual is able to communicate even if he was not able to contact the emergency services; - to determine that the first individual has regained his ability to communicate; - to be used by the interlocutor to supplement the analysis of the situation provided in the form of voice message(s) by the alert process; - or even to determine the presence of a second individual near the first individual capable of communicating with the interlocutor.

[0027] In particular embodiments, the method further comprises: - a voice synthesis of a message consisting of at least one piece of information from the following: o at least one piece of data obtained; o at least one piece of data provided by analysis of data obtained from at least one sensor; o at least one piece of information extracted by voice recognition of a voice signal coming from a device, the signal being one of the following: ■ a second voice message from the remote communication terminal with which the communication session is established; ■ a voice signal from a local audio sensor activated by the alert method; o at least one alert message, called the first message, generated based on one of the previous pieces of information; o at least one response message, called the third message, generated based on one of the previous pieces of information, the response message resulting from the second voice message coming from the remote communication terminal.

[0028] In particular embodiments, the method further comprises: - a voice recognition extracting information from a voice signal originating from a device, the voice signal being one of the following: o a second voice message originating from the remote communication terminal with which the communication session is established; o a voice signal from a local audio sensor activated by the alert method.

[0030] Each of these different particular modes of implementation can be implemented alone or in combination with one or more of the particular modes of implementation of the invention.

[0052] [Fig.6] Figure 6 schematically represents a second use case in accordance with the invention, in which a system comprises an alert communication device capable of communicating with a remote communication terminal, in particular an emergency service. Description of the embodiments

[0053] An alert situation is understood to mean any situation requiring external intervention, whether an alert situation relating to an individual requiring the intervention of a contact person, such as a friend, a family member, or more generally a relative (for example following a fall), or a specially mandated personal assistance service (nurse, nurse, etc.), or an emergency service (fire brigade, SAMU, police, etc.), or an alert situation relating to an empty environment (i.e. in the absence of any individual), etc.

[0054] Note that the figures below are described in a use case where a first individual is in the alert situation. However, the invention can be used when several first individuals are in the same alert situation: for example, a damaged vehicle with several first individuals on board, a passenger compartment (house, boat) in an alert situation such as a fire, grounding, etc. with several first individuals inside, etc. or when the environment of the alert situation does not contain anyone (no first individual) during the detection of an alert situation: detection of intrusion, fire, flooding... in the absence of residents.

[0055] Figure 1 represents, in simplified block diagram form, an example of a method for alerting a remote communication terminal, as implemented by the alert communication device 100 illustrated by way of example by Figure 3 or Figure 4.

[0056] In particular, when obtaining data S100, the alert communication device 100 obtains (S110), in particular data relating to a first individual, such as health data of the first individual and / or obtains (S120) data relating to an environment, in particular to the environment of the first individual when a first individual is present in the environment in which an alert situation is evaluated. The data obtained from at least one sensor are, for example, data among the following: - data relating to a first individual; - data relating to an environment; - data relating to the environment of a first individual; - data captured by at least one sensor connected to the device.

[0057] This step is notably implemented by the data obtaining module, also called MODJDBT data obtaining module, of the alert communication device 100. By data obtaining module is meant notably one or more of the following devices: a data receiver, a data reader, a data sensor of the alert communication device.

[0058] The data obtained from at least one sensor include: - data captured by one or more sensors of a local network 160 connected to said alert communication device 100 via a wired or wireless connection and received by the alert communication device 100 from the sensor(s) via the local network 160, - or even data captured by one or more sensors of said alert communication device 100.

[0059] Health data of a first individual means, in particular, physiological data, such as blood pressure, respiratory rate, heart rate and / or temperature, blood sugar level, and / or data relating to a change in the position of the first individual, such as loss of verticality (or fall) or absence of movement for a predetermined period, etc.

[0060] The health data is collected by various sensors, called health sensors, before being, where appropriate, transmitted regularly to the alert communication device 100. These health sensors take, for example, the form of a bracelet, a connected watch or a connected garment made of a textile material capable of capturing and recording or reacting to a signal or a stimulus.

[0061] Alternatively or additionally, obtaining health data results from an action by the first individual, for example pressing a button on a radio transmitter, such as a connected object, taking the form of a bracelet or a medallion, or directly on a button of the alert communication device (for example when it is implemented in a mobile telephone) so that the alert communication device 100 is informed that this first individual is in an alert situation, in particular that the first individual has just fallen.

[0062] By data relating to the environment, we mean the type of environment in which the alert communication device 100 is present, or even installed (e.g., whether it is a home, a means of transport, etc.), its location (e.g., its address and / or its geographical coordinates), the energy sources of the environment (gas and / or electricity supply, presence of an electric generator (e.g., battery), etc.), but also captured data (detection of smoke, fire, breakdowns, intrusion, etc.), in particular sound data captured, by one or more monitoring sensors: - either a local network 160 connected to said alert communication device 100 via a wired or wireless connection and received by the alert communication device 100 from the sensor(s) via the local network 160, - or said alert communication device 100 in the environment.

[0063] In particular, the alert method comprises a detection of an alert situation S200, in particular determining that the first individual is in an alert situation. The detection of an alert situation S200 is in particular determined as a function of data obtained from at least one sensor, for example by analysis of data obtained and / or sound data obtained from at least one sensor, such as those mentioned previously. Optionally, the detection of an alert situation S200 thus comprises an analysis of the data obtained and / or the sound data obtained providing an analysis result from which the alert situation is detected. The detection S200 is, in particular, implemented by the alert situation detector MOD_DET of the alert communication device 100.

[0064] In particular modes of implementation, the alert method, or even the detection of alert situation S200, in particular the analysis implemented by the detection of alert situation, comprises, in particular, a calculation of a value representative of a probability that the first individual is unable to contact a remote communication terminal, the calculation triggering the establishment of the communication session (S300) if said value is greater than a threshold value.

[0065] In particular modes of implementation, the analysis comprises, in particular, an evaluation of one or more values ​​collected by at least one of the sensors, for example by comparing the value collected by at least one of the sensors with a predetermined value, possibly stored in non-volatile memory 4 of the alert communication device 100.

[0066] In particular modes of implementation, the analysis includes: - a combination (also called “fusion”) of several data from one or more different sensors in order to generate a usable data set.

[0067] The S200 alert situation detection is then carried out, in particular, on the basis of this set of exploitable data. In particular, the analysis includes: - an assessment of the situation based on this set of exploitable data, in particular the type of situation: alert situation, or even emergency situation, or not.

[0068] In particular embodiments, the alert method comprises a determination of the remote communication terminal as a function of the detected alert situation, in particular the type of alert situation or the event which triggered the alert situation: fall, suffocation, heart problem, intrusion, smoke, etc.

[0069] In particular embodiments, the analysis comprises an interpretation of a signal transmitted by a radio transmitter and received by the alert communication device 100, following a specific action by the individual, for example pressing a button on this transmitter.

[0070] In particular modes of implementation, - obtaining comprises capturing sound signals by one or more audio sensors of the alert communication device 100 or connected to the alert communication device 100, - and the analysis includes detecting an alert voice signal in the captured sound signals, in particular by detecting, in a sound signal, an instruction to establish a communication session of said alert communication device with a remote communication terminal, in particular a terminal of an alert service, or even a remote communication terminal, for example “Call the fire brigade”.

[0071] Alternatively or additionally, the analysis comprises detecting in a captured sound signal one or more distress signals, also called “noises characterizing distress”. In this case, the analysis comprises, for example, a comparison of a signature of the sound signals with a plurality of signals characterizing the distress of an individual.

[0072] Alternatively or additionally, a spectral analysis of the captured sound sample makes it possible to determine whether the first individual is actually in an alert situation, particularly an emergency situation, or not.

[0073] The alert method according to the invention comprises establishing a communication session S300 between the alert communication device and a remote communication terminal triggered by a detection of an alert situation, in particular the detection of an alert situation S200, possibly based on data obtained from at least one sensor. Thus, if it is determined that the first individual is actually in an alert situation, the alert communication device 100 establishes communication with a remote communication terminal of a predetermined interlocutor, such as a relative; an alert service, in particular a personal assistance service, a monitoring service, etc.; an emergency service, such as the fire brigade, the police, etc. during the establishment of session S300.This session establishment is, in particular, implemented by the MOD_COM communication interface, also called communication manager, of the alert communication device 100.

[0074] In particular embodiments, the analysis carried out during the detection of an alert situation S200 comprises the calculation of a value representative of a probability that the first individual is unable to contact a remote communication terminal, and the establishment of a communication session S300 is carried out if this value is greater than a threshold value. By "inability to contact a remote communication terminal" is meant any inability to move, in particular to reach a communication terminal and / or the alert communication device and / or inability to communicate vocally with the interlocutor of the remote communication terminal, in particular inability to speak and / or inability to hear the interlocutor of the remote communication terminal and / or inability to respond to the interlocutor of the remote communication terminal (due to age, reduced mental capacity, in particular due to the alert situation, etc.).

[0075] In particular, the alert method further comprises: - a determination of the remote communication terminal based on the detected alert situation.

[0076] In particular modes of implementation, the establishment of a communication session comprises a telephone call to a remote communication terminal, in particular to a communication terminal of a relative or an alert service (pre-recorded number, for example), or even a communication terminal of an emergency service, for example by dialing 18, 112 or 196 for the fire department, 15 for the SAMU, 17 for the police, etc. When the communication session through the telecommunications network 200 complies with the Session Initiation Protocol, the establishment of a communication session comprises, for example, the transmission of an INVITE request, so that a The telecommunications network proxy 200 receives the IP address of the recipient and relays a message, in particular an alert message also called a first message and, possibly, one or more response messages, also called second messages, from said alert communication device 100 to said recipient. Alternatively or additionally, establishing a communication session includes opening channel 16 of the VHF marine band.

[0077] In particular, the alert method further comprises a transmission via the established communication session of a generated message, in particular as a function of data obtained from at least one sensor. Optionally, initially, upon establishment of the communication session, the alert method transmits a first generated message, also called an alert message, comprising, in a part of the generated message, information relating to the detected alert situation having triggered the establishment of the communication session, and another part of the generated message as a function of data obtained from at least one sensor, this other part of the generated message being distinct from the information part relating to the alert situation.

[0078] In particular, the alert method further comprises: - generation of an alert message, also called the first message, based on at least one of the following data: - at least one data item obtained from at least one sensor; - at least one data item provided by analysis of data obtained from at least one sensor, and the alert message is capable of being voice synthesized and transmitted, upon establishment of the communication session, in the form of a voice message via the established communication session.

[0079] In particular implementation modes, the first message generated includes information relating to the detected alert situation.

[0080] In particular embodiments, the first generated message includes presentation information indicating to the interlocutor that he is in communication with a digital device, such as an alert voice assistant, a bot, etc. implemented by the alert communication device 100. Thus, the interlocutor knows the nature of the caller: a device and not a human. The presentation is notably short because it is not the purpose of the communication session.

[0081] In particular, the method further comprises: - an S400 voice synthesis of a message made up based on at least one of the following information: - at least one data item obtained from at least one sensor; at least one data provided by analysis of data obtained from at least one sensor; - at least one piece of information extracted by voice recognition from a voice signal coming from one of the following devices: - the second voice message from the remote communication terminal with which the communication session is established; - a voice signal from a local audio sensor activated by the alert process; - at least one alert message, called the first message, generated based on one of the previous pieces of information; - at least one response message, called the third message, generated based on one of the previous pieces of information, the response message resulting from the second voice message coming from the remote communication terminal.

[0082] In particular, the method further comprises a voice synthesis S400 of data resulting from the analysis carried out during the detection S200, so as to enable the alert communication device 100 to communicate with a contact of the emergency service. This voice synthesis is, in particular, implemented by a voice synthesizer MOD_TX of the alert communication device 100.

[0083] In particular embodiments, the alert method further comprises: - an activation (S720) of a local audio sensor, the local audio sensor being one of the following audio sensors: - an audio sensor of said alert communication device 100; - an audio sensor connected to the alert communication device 100; the activation (S720) being triggered as a function of at least one of the following data: - at least one data item obtained from at least one sensor; - at least one data item provided by analysis of data obtained from at least one sensor; - at least one piece of information extracted by voice recognition from a voice message originating from the remote communication terminal with which the communication session is established.

[0084] In the case of activation triggered directly or indirectly by data obtained from at least one sensor, the data obtained makes it possible, in particular, to detect that the sound of the alert situation may be decisive for the analysis made by the interlocutor (identifiable sound picked up, conscious person, etc.), the sound signal picked up following activation of the sensor Audio is transmitted in addition to the first message, also called an alert message. For example, the first message is either superimposed on the captured audio, thus providing background audio for the first message, or transmitted first and followed by the captured audio.

[0085] In the case of activation triggered directly or indirectly by data obtained from at least one sensor, the data obtained makes it possible, in particular, to detect the presence of a second individual in the vicinity of the first individual. Optionally, the detection of the presence of the second individual automatically triggers the activation of the audio sensor and / or the loudspeakers. Thus, the alert method reduces the number of calls to the same alert or emergency service, or avoids multiplying the alert or emergency services contacted since the second individual will be put directly in contact without using his or her own communication terminal.

[0086] In particular, the alert method comprises in particular an activation of the audio sensor depending on the type of alert situation and / or the alert situation detection mode. Thus, when the alert situation establishes that the first individual is able to communicate even if he was unable to contact a remote communication terminal, the audio sensor, or even the loudspeakers of the alert communication device and / or connected to the alert communication device are automatically activated to allow dialogue between the first individual and the interlocutor of the remote communication terminal. The alert method will use the data obtained from at least one sensor to supplement the elements provided by the first individual to the interlocutor or possibly to introduce the first individual thanks to the first message.

[0087] In particular, the alert method further comprises: - a voice recognition extracting information from a voice signal coming from one of the following devices: - the second voice message from the remote communication terminal with which the communication session is established; - a voice signal from a local audio sensor activated by the alert process.

[0088] In particular modes of implementation, the interlocutor, who is not necessarily aware that he is communicating with a device, in particular an alert communication device, questions this alert communication device 100 as to the reasons for the call and the circumstances of the alert situation, in particular in order to determine the assistance procedure, in particular the emergency procedure, to be implemented. The alert communication device 100 is then configured to: transcribe a voice message from the interlocutor, also called a request message or instruction message or second message, into a second message usable by an analyzer message, in particular by voice recognition which transcribes the second voice message into a second text message and / or into useful data; - analyze the second transcribed message, the message analysis interprets the second transcribed message into one or more requests, in particular one or more requests from the following: o a request to configure an actuator to a given value; o an action instruction; o a request for information, data, etc. Thus, message analysis allows the alert communication device to “understand” the meaning of the second voice message from the interlocutor, i.e. the interlocutor’s request(s) relating to the alert situation. - generate a response message, also called a third message, based on the second transcribed message, in particular based on one or more responses to one or more requests from the second interpreted message; and, - vocally synthesize the third generated response message.

[0089] An inference engine implements in particular message analysis and / or response message generation. Message analysis and / or response message generation is implemented for example using a query and / or response database possibly updated by learning and / or by a neural network and / or more generally by artificial intelligence, etc.

[0090] An inference engine may include one or more of the following features: - an analyzer interpreting the transcribed message, - an action instruction analyzer interpreting the action instruction interpreted from the message transcribed into a command of an actuator, - a triggering controller: - + a setting to the required value to a required actuator, and / or - + a supply of information, data to a specific device based on the information, data required, and / or - + execution of a command by an actuator according to the required action instruction - an analyzer interpreting the responses provided either by the actuator or containing the required information or data and generating a response message based on the responses provided. The response message is notably written in natural language.

[0091] In particular embodiments, the alert method further comprises a control (S530, S630) of an actuator by means of a generated command (S520, S623) as a function of at least one element among the following: - the alert situation detected; - at least one data item obtained from at least one sensor; - at least one data item provided by analysis of data obtained from at least one sensor; - at least one piece of information extracted by voice recognition from a voice message originating from one of the following devices: - the remote communication terminal with which the communication session is established; - a local audio sensor connected to the communication device activated by the alert process.

[0092] In particular, the alert method further comprises generating a command S520, S623 as a function of at least one of the following: - the alert situation detected; - at least one data item obtained from at least one sensor; - at least one data item provided by analysis of data obtained from at least one sensor; - at least one piece of information extracted by voice recognition from a voice message originating from one of the following devices: - the remote communication terminal with which the communication session is established; - a local audio sensor connected to the communication device activated by the alert process.

[0093] So the command can be generated: - autonomously by the alert process depending on the alert situation detected and one or more data obtained from at least one sensor (for example, alert situation of the “fire” type and “open” gas supply, the command will then be the closing of the gas supply; or alert situation “fall down the stairs” and “locked” entrance door, the command will then be the unlocking of the entrance door or another opening of the house: French window, window, etc.); - based on a voice message instruction: - of the first individual unable to move; - the interlocutor of the remote communication terminal; - a second individual present at the scene of the alert, possibly after authorization from the first individual or the contact at the remote communication terminal.

[0094] For example, a second voice message contains the instruction based on which the command is generated. The second voice message comes from one of the following devices: - the remote communication terminal with which the communication session is established; - a local audio sensor connected to the communication device activated by the alert process.

[0095] In particular, the alert method further comprises, following a second voice message from one of the following devices: - the remote communication terminal with which the communication session is established; - a local audio sensor connected to the communication device activated by the alert process. A generation of a response message, also called a third message, based on at least one of at least the following data: - at least one data item obtained from at least one sensor; - at least one data item provided by analysis of data obtained from at least one sensor, - at least one piece of information extracted by voice recognition from the second voice message; and the response message is capable of being voice synthesized and transmitted, upon reestablishment of the communication session, in the form of a voice message via the established communication session.

[0096] For example, when the second message requires additional data, the third message includes, for example, for at least one of the required data for which values ​​have been obtained by the alert method, for example by consulting one or more memories and / or one or more sensors and / or one or more actuators, a value of the required data.

[0097] Alternatively or additionally, when the second message triggers a control of an actuator based on a command, the third message includes: - either simply an acknowledgment of implementation of the command by the actuator; or, more complexly, data obtained from the actuator and, possibly, other sensors following execution of the command by the actuator.

[0098] In particular, the alert method comprises voice recognition capable of extracting information from a voice signal originating from one of the following devices: - the second voice message from the remote communication terminal with which the communication session is established; - a voice signal from a local audio sensor activated by the alert process.

[0099] In particular embodiments, the alert communication device 100 continuously informs the interlocutor of the development of the situation. In this case, the alert method according to the invention comprises: - a transmission via the established communication session of a third voice message generated by voice synthesis based on the data obtained having evolved, the transmission having been triggered by an evolution of a value of at least one data item obtained towards a range of alert values.

[0100] Thus, if the device determines, for example, that the individual's respiratory rate is changing from 16 to 10 cycles per minute, i.e. towards an alert respiratory rate range (in this case less than 12 cycles per minute), the alert communication device 100 emits the following sentence: "The individual's respiratory rate is now 10 cycles per minute."

[0101] In particular, the alert process then comprises one or more of the following steps: - detection of changes in data obtained; - a detection that an obtained data item, in particular an obtained data item that has evolved, has a value included in a range of alert values.

[0102] In particular embodiments, the alert communication device 100 determines (S500), autonomously, the action(s) to be carried out taking into account the alert situation. The alert method according to the invention then comprises: - a determination (S510), autonomously and depending on the alert situation, of at least one action to be carried out by an actuator connected to the alert communication device 100; - obtaining (S520) a command associated with said action which can be interpreted by this actuator; and, - control (S530) of the actuator by means of this command.

[0103] In particular embodiments, the alert communication device 100 is configured to adapt (S600) the configuration of the individual's environment in response to a verbal instruction received from the emergency service contact. In this case, the method comprises: - receiving (S610) a voice instruction issued by the emergency service contact; - converting (S620) the received instruction into a command interpretable by an actuator connected to the alert communication device 100; and, - transmission (S630) of the command to this actuator.

[0104] In particular embodiments, the alert communication device 100 is configured to: - determining (S710) that a second individual is located in proximity to the first individual; and, - activating (S720) an audio sensor of said alert communication device 100.

[0105] In particular, the presence of a second individual is detected by one of the sensors of the local network 160, and the alert communication device 100 is then configured to activate the audio sensor of the alert communication device 100, in order to allow this second individual to communicate with the emergency service contact.

[0106] The alert communication device 100 has so far been described as a stand-alone device, but it could also be integrated into a mobile phone, and use the sensors of said phone to implement the invention.

[0107] Figure 2A represents, in the form of a simplified block diagram, an example of a method for alerting a remote communication terminal proposing a more detailed embodiment relating to the establishment of the communication session and the transmission of the first message to the communication terminal.

[0108] In particular, the alert method includes detection of an alert situation S200.

[0109] In particular, the alert method comprises a message generation S400 capable of generating a message based on data obtained from at least one sensor, in particular an alert message. Optionally, the message generation S400 comprises a voice synthesis S410 converting the message generated based on the data obtained from at least one sensor into a voice message. The message generation S400 is optionally triggered by an alert situation detection S200, the message thus generated is then an alert message ma, va.

[0110] The alerting method comprises an establishment S300 of a communication session between the alerting communication device implementing the alerting method and a remote communication terminal DCA, such as a communication terminal of an emergency service. In particular, the establishment of a communication session S300 comprises the exchange of a communication session establishment request com_req with the remote communication terminal DCA, for example to this remote communication terminal, triggering the opening of the communication session COM_SS, possibly following an agreement com_ack (not shown) from the remote communication terminal DCA.

[0111] The communication session SS_COM thus opened allows the alert communication device implementing the alert method and the remote communication terminal DCA to exchange messages either written or voice depending on the type of communication session opened (text and / or voice chat, voice calls, video calls, etc.). In particular, the establishment of the communication session S300 triggers (not shown) a generation S400 of an alert message depending on data obtained from at least one sensor, in particular following the opening of the communication session COM_SS.

[0112] The alert method then comprises a transmission S421 of an alert message ma, va, also called first message mssgl, vmssgl, generated based on data obtained from at least one sensor.

[0113] In particular, the alerting method comprises receiving a second message mssg2, possibly a voice message vmssg2, from the remote communication terminal. The second message is in particular a request from the interlocutor of the remote communication terminal: mssg2=reqi, vmssg2=vreqi. In the particular case of a second voice message, the alerting method comprises converting the voice message into text S621. Then, the alerting method possibly comprises determining the data and / or commands required in the second message S622.

[0114] In particular, the alert method comprises a consultation S624 of one or more databases, consulting in particular a database BDD comprising personal and / or environmental data recorded prior to the implementation of the alert method (for example during the installation and / or initialization of the alert method) and / or obtained by one or more sensors prior to their consultation, which makes it possible for example to consult a history of data obtained from at least one sensor over time ranges prior to the detection of the alert situation. The database is in particular implemented in the alert communication device or connected via a communication network to the alert communication device.The consultation S624 is triggered in particular as a function of the second message received S610 and / or the detected alert situation and / or the first message sent S421 (thus the alert communication device can autonomously search for additional data as a function of the alert message sent and / or the. alert situation detected while maintaining a complete but succinct alert message allowing the interlocutor to quickly analyze the situation and quickly trigger either a second message or directly an external intervention).

[0115] In particular, the alert method comprises a control S530, S630 of actuators and / or sensors by means of a command depending in particular on a second message originating from the remote communication terminal and / or the detected alert situation and / or the first message sent (thus the alert communication device can autonomously control additional data depending on the alert message sent and / or the detected alert situation).

[0116] In particular, the alert method comprises a generation S520, S623 of commands for actuators and / or sensors as a function, for example, of a second message originating from the remote communication terminal and / or the detected alert situation and / or the first message sent. In particular, a control S530, S630 of actuators and / or sensors, possibly implemented by the alert method, receives the command generated by the generation of commands S520, S623 implemented by the alert method.

[0117] An actuator is in particular a device controllable by another electronic device producing a physical phenomenon, such as a lamp (in particular LED), a switch, a motor, an audio and / or image and / or video player (screen, LCD display, indicator light, speakers, etc.), a fan, a valve, a cylinder, a resistor, etc. A sensor is an electronic device detecting a physical phenomenon, such as a push button; an audio sensor; a presence, smoke, leak, intrusion detector, etc.; a biometric sensor; etc.

[0118] Following control of an actuator, respectively of a sensor, by a command generated as a function of a second message coming from the remote communication terminal and / or of the detected alert situation and / or of the first message sent, the controlled actuator, respectively the sensor, provides at least one piece of data, such as data for acceptance of the command and / or one or more pieces of data resulting from the implementation of the command by the actuator, respectively the sensor (in this case data obtained by the sensor by implementation of the command).

[0119] In particular, the alert method comprises a generation S400 of a response message, also called a third message, either to a second message originating from the remote communication terminal or to the detected alert situation and / or to the first message transmitted, thus enabling the alert communication device to provide a message complementary to the alert message autonomously. The generation of the response message is in particular a function of at least one piece of data supplied by a consultation S624 and / or by at least one actuator, respectively at least one sensor, controlled as a function of a second message originating from the remote communication terminal, such as data for acceptance of the command and / or one or more pieces of data resulting from the implementation of the command by the actuator, respectively the sensor (in this case data obtained by the sensor by implementing the command).

[0120] Optionally, the message generation S400 comprises a voice synthesizer S410 converting the response message generated based on the data obtained from at least one sensor into a voice message.

[0121] The S400 generation of a response message is possibly triggered by the provision of data by the consultation and / or by an actuator and / or sensor, a control of an actuator and / or a sensor. In the case where the response message is generated following a reception of a second message from a remote communication terminal, the response message is generated when all or part of the data responding to the second messages have been provided.

[0122] Thus, when the data are provided at separate times, the message generation may include the generation of several response messages, a third message enabling the responses to be sent as and when data from a consultation is obtained, and / or data is provided by at least one actuator and / or at least one sensor. This avoids delays in providing information to the interlocutor of the remote communication terminal and therefore decision-making delays by this interlocutor. Note that the remote communication terminal may be equipped with a decision-making device capable of analyzing messages originating from any communication device (i.e., more generally, from a communication terminal used by a human) connected to the remote communication terminal.The alert process generating response messages as data is provided will thus reduce the time taken to assist in decision-making by the remote communication terminal.

[0123] Generating the message when all the data responding to the second message has been provided ensures that all requests from the interlocutor of the remote communication terminal will have been answered by the generated response message. This avoids decision errors due to a partial analysis of the situation by the interlocutor of the remote communication terminal, or even by the decision support device of the remote communication terminal.

[0124] In particular, the alert method then comprises a transmission S422 of a response message mansw, vansw, also called third message mssg3, vmssg3, generated as a function of data provided by a consultation, and / or an actuator and / or a controlled sensor, as a function either of a second message coming from the remote communication terminal or of the detected alert situation and / or of the first message transmitted.

[0125] Figure 2B represents, in the form of a simplified block diagram, an example of a method for alerting a remote communication terminal proposing a more detailed embodiment. relating to a connection between the interlocutor of the remote communication terminal and at least one second individual on the alert site (in particular near a first individual).

[0126] Figure 2B illustrates a particular case of Figure 2A in which at least one audio sensor and / or at least one loudspeaker is activated. The alert situation detection S200 has already established the communication session SS_COM and, possibly, issued the alert message.

[0127] In particular, the alert method comprises receiving a second message mssg2 1 , possibly vocal vmssg2 1 , from the remote communication terminal. The second message is in particular a request, coming from the interlocutor of the remote communication terminal, for activation: mssg 1, vmssgZ^ av_ act_req of an audio sensor, such as a microphone or a microphone array, and / or video, such as a camera, and / or at least one audio reproducer such as at least one loudspeaker or an audio reproduction system, in particular a 3D sound reproducer, etc. and / or video, such as a screen or a hologram, etc. In the particular case of a second voice message, the alerting method comprises a conversion of the voice message into text S621. Then, the alerting method optionally comprises a determination of the data and / or commands required in the second message S622.

[0128] In particular, the alert method comprises a control of audio and / or video sensors, and / or audio and / or video players S530, S630 by means of an activation command depending in particular on a second activation request message originating from the remote communication terminal and / or the detected alert situation and / or the first message transmitted (thus the alert communication device can autonomously activate a microphone and / or a loudspeaker depending on the alert message transmitted and / or the detected alert situation). The microphone will in particular allow the interlocutor of the remote communication terminal to hear the sound of the environment in the alert situation: crackling, etc., in particular the sounds emitted by the first individual: coughing, wheezing, etc.The loudspeaker, even if it does not allow dialogue with the first individual in certain situations - choking for example - will allow the interlocutor of the remote communication terminal to reassure him. In addition, the activation of a microphone and a loudspeaker by the alert method makes it possible to establish a dialogue between the first individual and the interlocutor of the remote communication terminal when the first individual is not able to approach the alert communication device.

[0129] In particular, the alert method comprises a generation of activation commands for sensors and / or audio and / or video players S520, S623 as a function, for example, of a second activation request message originating from the remote communication terminal and / or the detected alert situation and / or the first message sent. In particular, a control of activation of sensors and / or audio and / or video players, possibly S530, S630 implemented by the alert method, receives the command generated by the activation command generation S520, S623 implemented by the alert method.

[0130] Following an activation check of an audio and / or video player, respectively of an audio and / or video sensor, by an activation command generated as a function of a second activation request message originating from the remote communication terminal and / or of the detected alert situation and / or of the first message sent, the audio and / or video player, respectively the audio and / or video sensor, controlled provides at least one piece of data, such as data for acceptance of the command and / or one or more pieces of data resulting from the implementation of the command by the audio and / or video player, respectively the audio and / or video sensor (in this case data obtained by the sensor by implementation of the command).

[0131] In particular, the alert method comprises a transmission S423 of an activation message ack indicating that the sensor(s) and / or the audio and / or video player(s) is / are activated, also called third message mssg3 1 , vmssg3 1 =ack, generated following the activation of sensors and / or audio and / or video players, depending either on a second activation request message from the remote communication terminal or on the alert situation detected and / or the first message sent.

[0132] Then, the alert process may include receiving a new second message mssg2 2 , possibly vocal vmssg2 2 , from the remote communication terminal of the activation request message mssg2 1 . This new second message mssg2 2 , vmssg2 2is in particular a request from the interlocutor of the remote communication terminal. In particular, when an audio and / or video player has been previously activated, the new second message received is reproduced by this player (message written on a video / image player, voice message by an audio player).

[0133] The steps implemented by the alert process following receipt of this new second message mssg2 2 , vmssg2 2 are in particular those described in relation to figure 2A when receiving a second message mssg2, vmssg2 included, in particular: - a generation of a new S400 response message, also called new third message mssg3 2 , vssmg3 2 , to the new second message mssg2 2 , vmssg2 2from the remote communication terminal. The generation of this new response message is in particular a function of at least one piece of data provided by a consultation S624 and / or by at least one actuator, respectively at least one sensor (in particular, the data obtained by the at least one activated audio and / or video sensor, controlled according to a new second message from the remote communication terminal, such as data for accepting the command and / or one or more pieces of data resulting from the implementation of the command by the actuator, respectively the sensor (in this case data obtained by the sensor by implementing the command). Tl

[0134] Optionally, the message generation S400 comprises a voice synthesizer S410 converting the response message generated based on the data obtained from at least one sensor into a voice message.

[0135] The S400 generation of a response message is possibly triggered by the provision of data by the consultation and / or by an actuator and / or sensor, a control of an actuator and / or a sensor. In the case where the response message is generated following a reception of a second message from a remote communication terminal, the response message is generated when all or part of the data responding to the second messages have been provided.

[0136] In particular, the alert process then includes a transmission S422 of a new response message mansw, vansw, also called new third message mssg3 2 , vmssg3 2 , generated based on data provided by a consultation, and / or an actuator and / or a controlled sensor, based on either a new second message from the remote communication terminal.

[0137] Thus, the alert method can process several second messages and send back several third messages.

[0138] Figure 2C represents, in the form of a simplified block diagram, an example of S200 alert situation detection used and / or implemented by the alert method of a remote communication terminal.

[0139] In particular, the alert detection includes an activation S210 of an alert button by the first individual U 1 following in particular an alert action aa, for example pressing this alert button. The alert activation then triggers a_trg the detection of the alert.

[0140] In particular, the alert detection comprises a sound capture S220 of a voice signal coming from the first individual Ul. In order to determine whether the voice signal i / aa is a voice alert, the alert detection comprises in particular a verification of the content of the voice signal i / aa capable of determining whether the content of the voice signal vaa comprises a voice alert. When it is determined that the voice signal does not comprise an alert, the alert method is stopped S223 and the alert detection is reset. When it is determined that the voice signal comprises an alert, then the verification S222 triggers a detection of the alert a_trg(ta), a_trg(sa), a_trg(vaa)... possibly comprising the textual and / or sound and / or voice alert signal and / or any other element used during the verification S222.

[0141] For example, the alert detection includes a voice recognition S221 of the content of the voice signal i / aa by textualizing the captured voice signal; then, the alert detection checks S222 whether the recognized text signal ta includes an alert. The verification S222 of the content of the voice signal or sound signal (non-vocal sound extraction of the captured sound signal) or text is carried out in particular by comparing the content of the signal with a base of BKW audio alert signals and / or textual, in particular expressions, keywords, alert sounds {Ay}y, for example by comparing the signal with the elements of the alert signal base ta, sa = Ay.

[0142] In particular, the alert detection includes a situation analysis S250 based on captured data. The captured data are in particular personal data pd of the first individual U1 and / or environmental data of the environment E of the first individual Ul. The situation analysis is carried out in particular using an alert rule base BRA and / or by a neural network and / or artificial intelligence, etc. The situation analysis S250 then triggers an alert detection based on the personal data a_trg(pa), environmental data a_trg(ea), or both a_trg(pa,ea) by possibly transmitting the data that enabled the analysis to detect the alert situation.

[0143] In particular, the alert detection includes, prior to the situation analysis S250, a capture of data S230, S240, in particular at least one capture from among the following: - a capture of personal data S230; - an S240 environmental data capture.

[0144] Note that the optional steps of the alert method of Figures 2A, 2B and 2C may be implemented by the alert method itself or one or more methods distinct from the alert method possibly implemented by the alert communication device.

[0145] Figure 3 schematically represents an exemplary embodiment, in accordance with the invention, of an alert communication device capable of communicating with an emergency service.

[0146] Figure 4 schematically represents an example of hardware architecture of an alert communication device capable of communicating with an emergency service.

[0147] As illustrated in FIG. 4, the alert communication device 100 has the hardware architecture of a computer. Thus, the device comprises, in particular, a processor 1, a random access memory 2, a read-only memory 3 and a non-volatile memory 4. It also comprises a communication interface 5.

[0148] The read-only memory 3 of the system constitutes a recording medium as proposed, readable by the processor 1 and on which is recorded a computer program PROG in accordance with the invention, comprising instructions for the execution of steps of the alert method as proposed. The program PROG defines functional modules of the device 100 as represented in FIG. 3, which rely on or control the hardware elements 1 to 5 of the alert communication device cited above, and which include in particular: - a module (MODJDBT) for obtaining data, in particular health data of a first individual and / or data relating to the environment of the first individual, said data being captured by at least one sensor connected to said device; - an alert situation detector (MOD_DET) capable, in particular, of detecting that the first individual is in an alert situation, by analyzing the data obtained from at least one sensor; - an interface (MOD_COM) for communication between said device and a remote communication terminal, in particular an emergency service; - a voice signal operator (MOD_TX) comprising a voice synthesizer of the data resulting from said analysis. The voice signal operator is a device capable of processing voice signals by performing in particular a series of operations on a voice signal or providing a voice signal. An example of a voice signal operator is a voice signal processor, an electronic card for processing voice signals, etc. Thus, the alert communication device is capable of dialoguing with a human interlocutor of the remote communication terminal, without requiring the establishment of communication with a remote communication terminal capable of managing a “machine” caller.

[0149] In particular, the communication interface comprises a communication device capable of establishing a communication session. The communication interface and / or, where appropriate, the communication device, comprises a message transmitter capable of transmitting a message via the communication session established by the communication interface and, possibly, a receiver capable of receiving via the communication session established by the communication interface.

[0150] In particular, the obtaining module comprises at least one device among the following: - one or more sensors; - one or more receivers capable of receiving data captured by one or more sensors connected to the alert communication device via one or more separate communication networks (Bluetooth, Wifi, Ethernet, PLC; mobile communication network: 4G, 5G, etc.); etc.)

[0151] Furthermore, the alert communication device (100) may also comprise other functional modules or sub-devices, in particular capable of implementing particular modes of the alert method, as described in more detail later.

[0152] It should be noted in particular that the MOD_TX voice signal operator includes: - a natural language message analyzer, also called a natural language understanding analyzer, is configured in particular to understand the meaning of textual data; - a natural language generator (“Natural language generation” according to Anglo-Saxon terminology) is in particular configured to produce a text message in natural language from data obtained from at least one sensor, and this text message in natural language will possibly be converted into a voice message in natural language by the voice synthesizer; - a voice recognition operator, also called an automatic speech recognition operator, configured to analyze audio content, in particular a voice message, and transcribe it into text content, in particular a text message. The voice recognition operator is a device capable of processing voice signals by performing, in particular, a series of operations providing a voice signal. An example of a voice recognition operator is a voice recognition processor, a voice recognition electronic card, etc. In particular, the text message includes at least one piece of information extracted from the voice signal that can be used by the alert communication device.In particular, the alert communication device triggers, depending on the information extracted from the voice signal by voice recognition, either the obtaining of additional required data (included in the extracted information), or the control of an actuator depending on a command generated depending on the extracted information, etc.

[0153] It should also be noted that in particular embodiments, the alert communication device 100 relies on an inference engine to determine the response to be given to a question from an interlocutor. According to a first example, this inference engine is a rules engine comprising a set of inference rules and axioms, for example conforming to modal logic, for example to an epistemic modal logic which makes it possible to reason on the knowledge of both the agent and also to propose the assumed knowledge of other agents, such as for example the interlocutor of the emergency center. This set of rules and axioms can be regularly updated, for example by using machine learning mechanisms, or by receiving update data from a manager of the alert communication device 100.

[0154] In a second example, this inference engine implements “artificial intelligence”, and is for example based on a machine learning model, such as an artificial neural network.

[0155] In a third example, this inference engine uses a PDDL (“Planning Domain Definition Language”) type planning engine.

[0156] In addition, the inference engine may include one or more of the following features: - an analyzer interpreting the transcribed message, - an action instruction analyzer interpreting the action instruction interpreted from the message transcribed into a command of an actuator, - a triggering controller: - + a setting to the required value to a required actuator, and / or - + a provision of information, data to a specific device based on the information, data required, and / or - + execution of a command by an actuator according to the required action instruction, - an analyzer interpreting the responses provided either by the actuator or containing the required information or data and generating a response message based on the responses provided. The response message is notably written in natural language.

[0157] It should also be noted that in particular embodiments, the alert communication device 100 comprises: - audio sensors, such as an audio sensor, to capture the sound environment of the alert communication device 100; and / or - audio reproduction means, such as a loudspeaker, in order to be able to broadcast an audio message in the environment of said alert communication device 100. The audio reproduction means make it possible in particular to broadcast, in the environment of the alert communication device 100, a message received from the emergency service contact so that it can be heard by the individual in an alert situation.

[0158] The communication interface 5 allows in particular the alert communication device 100 to communicate with a telecommunications network 200, and with the electronic devices (actuators and / or sensors). To do this, the communication interface 5 comprises a communication interface, wired or wireless, capable of implementing any protocol supported by the telecommunications network 200.

[0159] Figure 5 schematically represents a first exemplary embodiment in accordance with the invention, of a system 1000 comprising an alert communication device 100 capable of communicating with an emergency service.

[0160] As illustrated in Figure 5, the system 1000 comprises an alert communication device 100, here installed within a home, and connected through a wired or wireless connection to a local network 160 comprising a plurality of electronic devices. These electronic devices may for example comprise an actuator 111 controlling a gas inlet 110, an actuator 121 controlling the opening and closing of an entrance door 120, a presence detector 130 configured to detect movement or infrared radiation emitted by a human body, a smoke and / or gas detector 140, and a connected watch 150. This connected watch 150 is configured to record the physiological data of an individual, such as their blood pressure, respiratory rate, heart rate and / or temperature, and transmit them regularly to the alert communication device 100. This connected watch 150 is also configured to transmit, at regular intervals, the position of the individual to the alert communication device 100.

[0161] The alert communication device 100 is also connected to an emergency service 300 via a telecommunications network 200, such as the Internet or a mobile telephone network, for example based on any of the technologies 2G (GSM) to 4G+ (“LTE Advanced”), 5G or even VHF. In particular, the ultra-reliable low-latency 5G technology (“Ultra-Reliable Low Latency Communications” according to English terminology) provides advantageous reliability in the event of an alert situation.

[0162] The device 100 is configured to analyze the data it receives from the various sensors, here the data captured by the presence detector 130, the smoke and / or gas detector 140, and the connected watch 150.

[0163] We now consider the scenario in which a fire breaks out in the home. The smoke and / or gas detector triggers an audible alarm, and transmits a smoke and / or gas detection signal to the alert communication device 100. Using the positioning data transmitted by the connected watch 150 and / or the data transmitted by the presence detector 130, the device 100 determines that an individual is present in the home, but that the latter is immobile.

[0164] The device 100 then determines that the individual is in an alert situation, since he risks being poisoned by the fumes at any time. The device 100 then communicates with an emergency service 300, such as the fire department, by calling 18 or 112. The caller (e.g., a firefighter) of the emergency service, who is not aware that it was an alert communication device 100 that generated the call, then asks the reason for the call. The alert communication device 100 responds to the caller that a fire has been detected, by transmitting a response message generated by voice synthesis. The caller then asks if people are in danger, and the alert communication device 100 analyzes the question and then responds in the affirmative by transmitting a new response message by voice synthesis.

[0165] The caller then requests the alert communication device 100 to secure the premises and facilitate access to emergency services. In response to receiving this voice instruction, the alert communication device 100: determines that the gas inlet shutoff valve 110 must be closed; converts this action into a command interpretable by the actuator 111; and, transmits a command to close the gas inlet shutoff valve 110.

[0166] In parallel, the alert communication device 100 transmits an unlocking command to the actuator 121 of the entrance door 120.

[0167] Figure 6 schematically represents a second exemplary embodiment in accordance with the invention, of a system comprising an alert communication device capable of communicating with an emergency service.

[0168] As illustrated in Figure 6, the system 1000 comprises an alert communication device 100, here on board a sailboat, and connected via a wired or wireless connection to a local network 160 comprising a plurality of electronic devices. These electronic devices may for example comprise an automatic pilot 120 (controlling an actuator capable of acting on the rudder of the sailboat according to a given instruction which may correspond to a heading or a speed), a navigation assistant (“Global Positioning System” according to English terminology) 110, an anemometer 130, and a connected life jacket 150.

[0169] The alert communication device 100 is also capable of contacting an emergency service 300, such as a Regional Operational Surveillance and Rescue Center (CROSS), via a telecommunications network 200 corresponding to a mobile telephone network, a radio network in the high frequency band (“Very High Frequency” or “Medium High Frequency” according to English terminology), or a satellite transmission network (e.g., INMARSAT, COPSAS-SARSAT).

[0170] This radio equipment may be associated with a “Digital Selective Calling” device. The system 1000 may also include an automatic identification system, or AIS receiver, in order to be able to know all the vessels located near said sailboat (eg, 15-20 nautical miles away) and equipped with an AIS transmitter, but also VHF equipment, this VHF equipment being able to

[0171] We now consider the scenario where, during a maneuver, the helmsman who was alone on board the sailboat falls into the water. In response to the detection of a fall into the water, the connected life jacket 150 transmits a distress signal to the alert communication device 100.

[0172] In response to receiving such a signal, the alert communication device 100 determines that the individual is in an alert situation, and transmits commands to the autopilot 120 so that the sailboat adapts its trajectory and speed. More precisely, taking into account the direction of the wind provided by the anemometer and the geographical position that the sailboat had when the connected life jacket 150 emitted the distress signal, the alert communication device 100 provides heading instructions to the autopilot 120, so that the sailboat approaches the person in the water.

[0173] In parallel, the alert communication device 100 connects to channel 16 of the VHF marine band, then transmits a distress message by voice synthesis which includes the following indications: “mayday mayday mayday; name of the sailboat repeated three times; geographical coordinates of the sailboat; cause of the call”.

[0174] The distress signal is intercepted by a contact (e.g., a military personnel from the French Navy) from CROSS who is not aware that it is an alert communication device that generated the call, and who then requests clarification.

[0175] The alert communication device 100 transmits a response message by voice synthesis, and responds to the interlocutor that the helmsman has fallen into the water and that a man overboard maneuver is in progress.

[0176] The particular embodiments described in connection with the figures may be implemented alone or in combination with one or more other particular embodiments described.
