Controller for controlling a personal road signaling means and headgear comprising same, neural stimulator, personal road signaling means, method for controlling personal road signaling means, and personal road signaling method

Abstract

The invention relates to the personal road signaling of the road behaviour of a vulnerable first user of a road. The invention relates to a controller for controlling a personal road signaling means, connected to a road signaling means carried by a first road user, referred to as the personal road signaling means, said personal road signaling means being able to provide a road indication to a second user of the road, and the controller for controlling the personal road signaling means comprising a trigger for activating indicators of the personal road signaling means, the trigger being able to activate a given indicator of the personal road signaling means as a function of a neural frequency of a brain signal from the first road user, different from the second road user. In this way, since the user does not have to change direction using just one hand, they will have better control of the vehicle and the path of the vehicle will be less likely to cause an accident. Furthermore, since the indicator is triggered as a function of a specific brain activity, simply concentrating on the road behaviour change (change of direction, stopping, etc.) will trigger the indicator, thus avoiding the risk of no indication being given for a road behaviour change.

Description

Individual road signal controller and headgear comprising it, Neural stimulator, Individual road signaling, individual road signaling control method and individual road signaling method

[0001] The invention relates to individual road signaling of road behavior of a first road user, in particular a first vulnerable road user. These vulnerable road users are in particular non-motorized road users: pedestrians, roller skaters, skateboards, bicycles, scooters, etc., but also light electric vehicles such as electrically assisted bicycles, electric scooters, etc., more generally called "pedestrians" or "very light vehicles". We also speak of road users without a body. State of the art

[0002] Worldwide, more than 1.3 million people die on the roads each year, around 3,000 in France. These figures have remained stable in France since 2019. However, since the explosion of so-called "soft" mobility, the number of road fatalities among road users using soft modes of mobility has exploded in a worrying manner: a 30% increase in deaths among cyclists, and a 180% increase in road users of scooters, ... in three years.

[0003] These road users are vulnerable because they do not have external status indicators such as brake lights, turn signals, including indicators, etc. This is why the main reason for accidents is the inability of other road users to detect and perceive upcoming dangers before the time necessary for the reaction taken to avoid accidents! Indeed, it is complicated for other road users to anticipate the behavior of a first vulnerable road user, particularly a cyclist: for example, the direction they will take at an intersection, a crossroads or a roundabout; the slowing down or even the stopping of the first vulnerable road user; etc.

[0004] In the example of the cyclist, the cyclist can indicate a change of direction to other road users by extending an arm to one side or the other. This solution can also be used by other vulnerable road users such as a scooter user. However, vehicle users are not always comfortable managing both the direction indication with one arm and the manipulation of the handlebars with the other hand to change direction. In addition, indicating the change of direction simply by the arm has limited visibility, especially in traffic situations with poor visibility (rain, fog, etc.) or at night. This can therefore lead either to a change of direction indicated but with a zigzag trajectory, or a change of direction indicated but difficult to see or even invisible, or even to a lack of indication of change of direction which are accident-prone.

[0005] Solutions have been implemented to improve the visibility of these vulnerable road users when changing direction. In particular, the first vulnerable road user putting on a vest to improve their visibility to other road users can choose a vest with indicators; and / or the first vulnerable road user equipping themselves with a protective helmet can choose a protective helmet with indicators. Today, the activation of one of the indicators fitted to such protective clothing (vest, helmet, etc.) of the first vulnerable road user is carried out by the first road user pressing a button either on a remote control or on a touch screen of a smartphone placed on the handlebar.The remote control or the window of the turn signal control application displayed by the smartphone touch screen has at least two buttons: - a first button with an arrow to the left to trigger the turn signal indicating a change of direction to the left; - a second button with an arrow to the right to trigger the turn signal indicating a change of direction to the right. However, if this solution provides better visibility of the change of direction, it does not resolve the problem of difficulty in managing the change of direction properly and the indication of this with a risk of indication of the change of direction but with a zigzag trajectory or even a lack of indication of change of direction which are accident-prone.

[0006] One of the aims of the present invention is to remedy drawbacks of the state of the art.

[0007] An object of the invention is an individual road sign controller connected to road signs carried by a first road user, called individual road signs, the individual road signs being capable of providing a road indication intended for a second road user, the controller comprising a trigger for indicators of the individual road signs, the trigger being capable of activating a given indicator of the individual road signs as a function of a neural frequency of a brain signal of a first road user distinct from the second road user.

[0008] Thus, the first road user, not needing to change direction with one hand, will have better control of their vehicle and therefore a less accident-prone trajectory. In addition, since the indicator is triggered based on specific brain activity, simply concentrating on the change in road behavior (change of direction, stopping, etc.) will trigger the indicator, thus avoiding the risk of no indication of a change in road behavior.

[0009] Advantageously, the individual road signal controller comprises a brain signal analyzer of a first road user capable of determining a neural frequency of the analyzed brain signal, the brain signal being provided by a direct neural interface.

[0010] Advantageously, the individual road sign controller comprises a coupler capable of associating, for each indicator of the individual road sign, a given frequency of a stimulus with an indicator of the individual road sign, the neural frequency being a function of the given frequency associated with the given indicator.

[0011] Thus, brain analysis is facilitated because the triggering of a predetermined individual road sign indicator is implemented when a neural frequency that is a function of a given frequency of a stimulus is detected, the given frequency being previously associated with the predetermined individual road sign indicator. Therefore, the first road user of the road simply focuses on the stimulus whose frequency is associated with the individual road sign indicator that he wishes to trigger. The risk of erroneously triggering an individual road sign indicator or not triggering an individual road sign indicator because the detection of a neural frequency is simpler and less prone to detection errors and non-detections.

[0012] Advantageously, the individual road sign controller comprises a stimulus generator capable of generating, for each individual road sign indicator, a stimulus with a given frequency associated with an individual road sign indicator, the stimuli being supplied to a neural stimulator.

[0013] An object of the invention is also a neural stimulator comprising a stimuli reproduction interface, the given frequency of a stimulus being associated with a given indicator of a road sign carried by a first road user, called individual road signage, the individual road signage being capable of providing a road indication intended for a second road user, each stimulus having a distinct frequency.

[0014] Advantageously, the reproduction interface is capable of reproducing one or more of the following types: - auditory stimuli; - visual stimuli.

[0015] Thus, the stimulus can be adapted to the environment: a visual stimulus being more suitable in a noisy environment avoiding the risks that the stimulus is not audible and therefore the individual road sign indicator is not triggered, an auditory stimulus being more suitable in a visually loaded environment, in particular an urban environment with high road density avoiding the risks of hindering the reading of this urban environment by the stimulus.

[0016] Advantageously, the reproduction interface is a three-dimensional reproduction interface capable of reproducing the stimulus in a location associated with a given indicator, the given indicator being associated with the stimulus to be reproduced.

[0017] Thus, the stimulus for changing direction to the left will be reproduced on the left of the first road user and that for changing direction to the right on the right of the first road user, facilitating the selection and concentration of the user on the desired stimulus to correctly control the individual road sign indicator.

[0018] An object of the invention is also a road sign carried by a first road user, called individual road sign, comprising an actuator capable of controlling an indicator of the individual road sign as a function of a trigger command for an indicator, the indicator being capable of providing a road indication intended for a second road user, the trigger command being a function of a neuronal frequency of an analyzed cerebral signal of the first road user distinct from the second road user.

[0019] Individual road signs are understood to mean any installation, device of indication signals such as indicators, stop lights, hazard lights, etc. associated with an individual road user.

[0020] Advantageously, the individual road signage comprises one or more indication devices from among the following:- one or more indicator devices, also called indicators, each indicator device being capable of reproducing a distinct indication information; and- a reproduction interface capable of reproducing several distinct indication information in the form of indicator signals, also called indicators.

[0021] Advantageously, the indicator is an indicator of one or more of the following types of indicators: - a visual indicator; - an audible indicator.

[0022] An object of the invention is also a headdress comprising:- a direct neural interface providing brain signals from a first road user; and- an individual road sign controller comprising a trigger for indicators of the individual road sign, the indicator being capable of providing a road indication to a second road user, the trigger being capable of activating a given indicator of the individual road sign as a function of a neural frequency of the brain signal of the first road user distinct from the second road use.

[0023] Headgear (called "hat" in English for equipment covering the head which is not part of a garment) is understood to mean any flexible or rigid equipment covering the head such as a bonnet, a cap, a helmet, a protective helmet, etc.

[0024] Advantageously, the headdress includes individual road signs, the individual road signs including an indicator capable of being triggered by the traffic controller.

[0025] Advantageously, the headgear comprises an interface for reproducing stimulation signals with given frequencies previously associated with the indicators of individual road signs, the stimulation signals being supplied to the reproduction interface.

[0026] Advantageously, the reproduction interface comprises one or more of the following reproduction interfaces: - an audio headset; - a bone conduction headset; and - augmented reality glasses.

[0027] An object of the invention is also a method for controlling individual road signs implemented by a controller connected to road signs carried by a first road user, called individual road signs, the control method comprising management of indicators of the individual road signs, the management triggering a given indicator of the individual road signs as a function of a neuronal frequency of a brain signal of a first road user distinct from the second road user.

[0028] Another object of the invention is a method of individual road signaling comprising controlling an indicator of the individual road signaling as a function of a trigger command for an indicator, the trigger command being a function of a neuronal frequency of a brain signal from a first road user.

[0029] Advantageously, according to an implementation of the invention, the different steps of at least one method according to the invention are implemented by software or computer program, this software comprising software instructions intended to be executed by a data processor of a device, in particular an individual road sign controller, individual road signage, etc. and being designed to control the execution of the different steps of this method.

[0030] The invention therefore also relates to a program comprising program code instructions for executing the steps of the individual road sign control method and / or the individual road sign method according to the invention when said program is executed by a processor.

[0031] This program may use any programming language and be in the form of source code, object code, or code intermediate between source code and object code, such as in a partially compiled form or in any other desirable form.

[0032] The characteristics and advantages of the invention will appear more clearly on reading the description, given by way of example, and the figures relating thereto which represent:

[0033] , a simplified diagram of an individual road signal controller according to the invention and its implementation in a communication architecture comprising in particular a neural stimulator interface according to the invention and / or individual road signaling according to the invention;

[0035] , a simplified diagram of the exchanges during the implementation of the individual road sign control method and the individual road sign method according to the invention.

[0036] In the following description, the term "first road user" means a vulnerable first road user. In particular, the vulnerable first road user is a pedestrian, an individual traveling on roller skates, skateboard, bicycle, scooter, etc., but also in a light electric vehicle such as an electrically assisted bicycle, an electric scooter, etc.

[0037] In the following description, a second road user is understood to mean any road user other than the first road user. In particular, the second road user is either a vulnerable road user or a road user driving a road vehicle (car, coach, truck, etc.), i.e. a human but also an autonomous driving device or a driving assistance device for a road vehicle.

[0038] Illustrates a simplified diagram of an individual signaling controller, in particular an individual road signaling controller, according to the invention and its implementation in a communication architecture comprising in particular a neural stimulator interface according to the invention and / or individual signaling, in particular individual road signaling, according to the invention.

[0039] The individual signaling controller 3, in particular the individual road signaling controller, also called signaling controller, is connected to an individual signaling, respectively an individual road signaling 4. It comprises a trigger 33 of indicators of the individual signaling, respectively a trigger of indicators of the individual road signaling, the trigger 33 being able to activate a given indicator 42n, 42n s of individual signaling 4, respectively a given indicator of individual road signaling 4, as a function of a neural frequency f ecg of a brain signal sc of a first road user.

[0040] In the particular embodiment of an individual road sign controller, the road sign carried by a first road user is called individual road sign.

[0041] In particular, individual road signs are capable of providing road indications to a second road user.

[0042] In particular, the individual signaling controller 3, in particular the individual road signaling controller, comprises an analyzer 32 of brain signals from a first road user capable of determining a neuronal frequency f ecg of the analyzed brain signal sc of the first road user, the brain signal sc being provided by a direct neural interface 2.

[0043] In particular, the signaling controller 3 is capable of triggering a road signal indicator as a function of a neural frequency of a brain signal from a first road user when this first road user pays attention, or even concentrates, on a stimulus associated with this indicator.

[0044] Thus, the first user is active in the use of the individual signal controller. This avoids untimely signal indications, particularly when the first user is thinking during his current journey at a later stage of his route or anticipates a change in road behavior giving inappropriate or overly anticipated indications to the second road user(s).

[0045] In particular, the individual signaling controller 3, in particular the individual road signaling controller, comprises a coupler 30, 301 capable of associating, for each indicator 421,…, 42n,…, 42N, 421 s ,…,42n s ,…,42N s of individual signaling, in particular each indicator of individual road signaling 4, a given frequency {fn} n > = f1…fn…fN of a stimulus st, {st n} n to an indicator 421,…, 42n,…, 42N, 421 s ,…,42n s,…,42N s of individual signaling, in particular to an indicator of individual road signaling, the neural frequency f ecg being a function of the given frequency fn associated with the given indicator 42n, 42n s .

[0046] In particular, the individual signaling controller 3, in particular the individual road signaling controller, comprises a stimulus generator 311 capable of generating, for each indicator 421,…, 42n,…, 42N, 421 s ,…,42n s ,…,42N s of individual signaling, in particular for each indicator of individual road signaling 4, a stimulus with a given frequency {st(fn)} n , {st n (fn)} n associated with an indicator 421,…, 42n,…, 42N, 421 s ,…,42n s ,…,42N s individual signaling, in particular an individual road signal indicator 4, the stimuli {st(fn)}n , {st n (fn)} n being supplied to a neural stimulator 1.

[0047] The neural stimulator 1 comprises a stimuli reproduction interface 10, the given frequency fn of a stimulus st, st n being associated with a given indicator 42n, 42n s of an individual signal 4, in particular a given indicator of an individual road signal 4, each stimulus st, st n having a distinct frequency fn.

[0048] In particular, the reproduction interface 10 is capable of reproducing one or more types of stimuli among the following: - auditory stimuli; - visual stimuli.

[0049] In particular, the reproduction interface 10 is a three-dimensional reproduction interface capable of reproducing the stimulus in a location l n associated with a given indicator 42n, 42n s , the given indicator 42n, 42n sbeing associated with the stimulus to be reproduced st(fn), st n (fn).

[0050] The individual signaling 4, in particular the individual road signaling, also called signaling 4, comprises an actuator 41 capable of controlling an indicator 421,…,42n,…,42N, 421 s ,…,42n s ,…,42N s individual signaling, in particular an indicator of individual road signs depending on a command to trigger an indicator sig_cmd(i n ), trg(i n ), the trigger command sig_cmd(i n ), trg(i n ) being a function of a neuronal frequency f ecg of a brain signal analyzed sc.

[0051] In particular, the individual signage 4, in particular the individual road signage, comprises one or more indication devices from among the following:- one or more indicator devices 421,…,42n,…,42N, also called indicators, each indicator device 421,…,42n,…,42N being capable of reproducing a distinct indication information; and- a reproduction interface 42 capable of reproducing several distinct indication information {i n} n in the form of indicator signals 421 s ,…,42n s ,…,42N s , also called indicators.

[0052] In particular, the controller 2 comprises a coupler 30, 301 capable of associating a given frequency fn with a stimulus st(fn), st n (fn) capable of being reproduced by a neural stimulator 1 to an indicator 42n, 42n s of individual signaling 4.

[0053] Thus, a given frequency fn of reproduction of a stimulus by a neural stimulator 1 connected to a communication network 6 is associated by the signaling controller 3 with an indicator 42n, 42n s of an individual signaling 4 connected to the communication network 6.

[0054] In particular, the coupler 30 comprises a storage device 300 for given indicator pairs – given frequencies (i i , fi) i=1…n…N . The storage device 300 is a memory, a signaling indicator base, etc.

[0055] In particular, the coupler 30,301 comprises a recorder (not shown) capable of storing the given indicator pair – given frequency (i n , fn), in particular in a storage device 300.

[0056] In particular, a communication terminal of the first road user comprises a configuration interface (not shown) of the signaling controller 3. This configuration interface allows the first road user to command the coupler 30, 301 of the signaling controller 3 to associate a given indicator 42n, 42n s of individual signaling 4 at a given frequency fn of the neural stimulator 1. The configuration interface is notably implemented on the communication terminal in the form of an application.

[0057] In particular, the controller 3 comprises a generator 311 of stimulation signals {sst(fn)} n , {sst n (fn)} n to be reproduced at the given frequencies {fn)} n . The stimulation signals {sst(fn)} n , {sst n (fn)} n thus generated are capable of being reproduced by a neural stimulator 1.

[0058] In particular, the signaling controller 3 comprises a transmitter 310 exchanging signals i({fn)} n ), {sst(fn)} n , {sst n (fn)} n relative to the given frequencies {fn)}n with the neural stimulator 1.

[0059] In particular, the signal relating to the given frequency fn is one of the following signals:- an indication signal i({fn)} n ) of the given frequencies {fn)} n emitted by controller 3 to neural stimulator 1;- stimulation signals {sst(fn)} n , {sst n (fn)} n to be reproduced at the given frequencies {fn)} n generated and emitted by controller 3 to the neural stimulator 1;- an indication signal i({fn)} n ) of the given frequencies {fn)} n emitted by the connected neural stimulator 1 to the controller 3.

[0060] In particular, the signaling controller 3 transmits, in particular by means of a transmitter 310 and / or more particularly a transmitter, to the neural stimulator 1 stimulation signals {sst(fn)} n , {sst n (fn)} n to be reproduced at the given frequencies {fn)} n or an indication signal i({fn)} n ) of the given frequencies {fn)} n . The stimulation signals {sst(fn)} n , {sst n (fn)} n to be reproduced at the given frequencies {fn)} n emitted by the signaling controller 3 being possibly generated by the signaling controller 3, in particular by a stimuli generator 311.

[0061] In particular, the transmitter 310 comprises a transmitter of the signal relating to the given frequency fn intended for the neural stimulator 1.

[0062] In particular, the transmitter 310 comprises an indication signal receiver i({fn)} n) of the given frequencies {fn)} n from neural stimulator 1.

[0063] In particular, the neural stimulator 1 comprises a transmitter 110 exchanging signals i({fn)} n ), {sst(fn)} n , {sst n (fn)} n relating to the given frequencies {fn)}n with the signaling controller 3.

[0064] The neural stimulator 1 includes in particular a transmitter 110 capable of transmitting:

[0065] - an indication signal i({fn)} n ) of the given frequencies {fn)} n emitted by the connected neural stimulator 1 to the controller 3.

[0066] The neural stimulator 1 includes in particular a receiver 110 capable of receiving:

[0067] - either an indication signal i({fn)} n ) of the given frequencies {fn)} n emitted by controller 3 to neural stimulator 1;- either stimulation signals {sst(fn)} n , {sstn (fn)} n to be reproduced at the given frequencies {fn)} n generated and emitted by controller 3 to neural stimulator 1.

[0068] In particular, the neural stimulator 1 comprises a generator 11 of stimulation signals {sst(fn)} n , {sst n (fn)} n to be reproduced at the given frequencies {fn)} n for example depending on the given frequencies {fn)} n received with the indication signal i({fn)} n ) of the given frequencies {fn)} n from controller 3. The stimulation signals {sst(fn)} n , {sst n (fn)} n thus generated are capable of being reproduced by the neural stimulator 1. In particular, the generator 11 provides the generated stimulation signals {sst(fn)} n , {sst n (fn)} n possibly to the reproduction interface 10.

[0069] In particular, a neural stimulator 1 is capable of reproducing stimuli {st(fn)} n , {st n (fn)} n at the given frequencies {fn} n . Optionally, a given frequency fn is associated by the controller 3 with a given indicator 42n, 42n s of an individual signaling 4. The neural stimulator 1 is distinct from the individual signaling 4. Optionally the neural stimulator 1 and / or the individual signaling 4 are connected to a communication network 6.

[0070] Thus, the individual signaling 4 generally placed on the back of the first road user U not allowing visual stimulation of the first road user can nevertheless have a so-called BCI function added, i.e. neural interface, by means of the neural stimulator 1 and the signaling controller 3 according to the invention.

[0071] In particular, the reproduction interface 10 of the neural stimulator 1 reproduces the stimuli at the given frequencies {st(fn)} n , {st n (fn)} n , especially after receiving the stimulation signals {sst(fn)} n , {sst n (fn)} n to be reproduced at the given frequencies {fn)} n or an indication signal i({fn)} n ) of the given frequencies {fn)} n , in particular by means of a receiver 110 and / or or generation of stimulation signals {sst(fn)} n , {sst n (fn)} n to be reproduced at the given frequencies {fn)} n in particular by means of a stimuli generator 311, 11. Optionally, the neural stimulator 1, in particular by means of a stimuli generator 11, is capable of generating stimulation signals {sst(fn)} n , {sst n (fn)} n to be reproduced at the given frequencies {fn)} n depending on the indication signal i({fn)} n) of the given frequencies {fn)} n received from signal controller 3.

[0072] In particular, the reproduction interface 10 of the neural stimulator 1 comprises: - an audio reproduction interface 101 capable of reproducing the auditory stimuli {sa n} n at the given frequencies {fn} n . The audio reproduction interface 101 is in particular suitable for 2D, stereo, 3D, etc. audio reproduction. The audio reproduction interface 101 is in particular an audio headset equipped with two speakers suitable for being placed against the ears, in particular a stereo headset, one or more earphones, a bone conduction headset, etc. connected wired or wirelessly to the other equipment of the neural stimulator 1.- a visual reproduction interface 102 suitable for reproducing the visual stimuli {sv n} n at the given frequencies {fn} nThe visual reproduction interface 102 is in particular a 2D, 3D, etc. screen, one or more light-emitting diodes or lasers (in particular a mosaic of light-emitting diodes), a holograph, etc.

[0073] The neural stimulator 1, in particular the reproduction interface 10 and / or the visual reproduction interface 102, displays visual stimuli {sv n} n at the given frequencies {fn} n when reproducing visual stimulation signals {ssv n} n at the given frequencies {fn} n . Visual stimuli {sv n} n are perceptible, visible to a first user of the road U.

[0074] The neural stimulator 1, in particular the reproduction interface 10 and / or the audio reproduction interface 101, broadcasts auditory stimuli {sa n} n at the given frequencies {fn} nwhen reproducing auditory stimulation signals {ssa n} n at the given frequencies {fn} n . Auditory stimuli {sa n} n are perceptible, audible by a first user of the road U.

[0075] In particular, the stimuli make it possible to reproduce information indicating which indicator of the signaling they are associated with and / or to be reproduced at a location indicating which indicator of the signaling they are associated with. In particular, a visual stimulus can reproduce:- an arrow going to the right, respectively to the left, and / or in the right part, respectively left, of a reproduction device, such as a screen or a virtual environment, relative to the first road user, if it is associated with a “right flashing” indicator, respectively “left”;- a symbol associated with braking such as the P for parking if it is associated with a “brake light” indicator;- a symbol associated with a breakdown or an emergency such as the two triangles inserted one inside the other if it is associated with a “hazard warning light” indicator; etc.and a stimulus can reproduce:- a set of words indicating a possible future action of the first road user;- a word and / or a sound associated with a side: right, respectively left, and / or with a location located to the right, respectively left, of the first road user, if it is associated with a “flashing right”, respectively “left” indicator;.

[0076] - a word and / or an indicator sound associated with braking such as the P for parking if it is associated with a “brake light” indicator;- a word and / or an indicator sound for breakdown or an emergency such as the two triangles inserted one inside the other if it is associated with a “hazard light” indicator;- a word and / or an indicator sound, in particular a reversing beep, associated with the reversing action, if it is associated with an audible reversing indicator such as a reversing beep audible to other road users including drivers of heavy vehicles: cars, buses, trucks, etc. and / or a visual reversing indicator: “reversing light”;- etc.

[0077] A direct neural interface 2 is capable of capturing a brain signal sc relating to a first road user U during a reproduction of stimuli {st(fn)} n , {st n (fn)} n having a given frequency {fn} n .

[0078] In particular, the direct neural interface 2 is capable of capturing and / or detecting a neural frequency fecg of a brain signal sc relating to a first road user U during a reproduction of stimuli {st(fn)} n , {st n (fn)} n having a given frequency {fn} n .

[0079] In particular, the direct neural interface 2 is capable of being connected to a signaling controller 3, in particular using the communication interface of the direct neural interface.

[0080] In particular, a direct neural interface 2 is capable of providing the signaling controller 3 with either a brain signal sc captured during a reproduction of stimuli {st(fn)} n , {st n (fn)} n having a given frequency {fn} n , or a neuronal frequency f ecg of the brain signal sc captured during a reproduction of stimuli {st(fn)} n , {st n (fn)} nhaving a given frequency {fn} n . In particular, the direct neural interface 2 provides the brain signal sc, or even the neural frequency f ecg, via the communication network 6.

[0081] In particular, the direct neural interface 2 comprises a communication interface (not shown) of the brain signal sc, or even of the neural frequency f ecg of the brain signal sc to a signaling controller 3. Thus, the communication interface is able to transmit to the signaling controller 3 the brain signal sc or even, where appropriate, the neuronal frequency f ecg of the brain signal sc captured during a reproduction of stimuli {st(fn)} n , {st n (fn)} n having a given frequency {fn} n by neural stimulator 1.

[0082] The neural frequency f ecgis a frequency of an evoked potential signal in brain signals sc, also called electroencephalogram signals, of a first road user U. The neuronal frequency f ecg is a function of the given frequency fn of a stimulus that the first road user looks at or focuses on.

[0083] Thus, when the first road user U focuses on one of the stimuli st(fn), st n (fn) resulting from the reproduction, by the neural stimulator 1, of a stimulation signal sst(fn), sst n (fn) with one of the given frequencies fn, more particularly when looking at one of the visual stimuli sv(fn) resulting from the reproduction, by the neural stimulator 1, of one of the visual signals sv(fn) with the given frequency fn, a direct neural interface 2 captures a neural frequency f ecg relative to the first road user U. The captured neural frequency fecg and the given frequency fn have the same value.

[0084] In particular, when the first road user U looks at a visual stimulus st(fn)=sv(fn), st n (fn)=sv n (fn) resulting from the reproduction of the visual signal sv, sv n with the frequency given fn by the neural stimulator 1, and / or when the first road user focuses on a stimulus st(fn)=sv(fn), st n (fn)=sv n (fn) resulting from the reproduction of the visual signal sv, sv n with the frequency given fn by the neural stimulator 1, a direct neural interface 2 captures a brain signal sc relating to the first road user U having a neural frequency f ecg . The neural frequency f ecg and the given frequency fn have the same value.

[0085] In particular, the communication interface of the direct neural interface 2 is a transmitter via a communication network 6. The direct neural interface 2 then provides, in particular by means of the transmitter, the cerebral signal sc, or even the neural frequency f ecg of the brain signal sc, via the communication network 6, in particular to the signaling controller 3. In particular, the transmitter of the direct neural interface 2 is capable of providing the neural frequency f ecg relative to a first road user U, for example the neural frequency f ecg of the brain signal sc captured, during a reproduction of stimuli {st(fn)} n , {st n (fn)} n with a given frequency {fn} n by a neural stimulator 1, in particular connected to the communication network 6.

[0086] Thus, when the communication interface of the direct neural interface 2 is a transmitter, it makes it possible to have a signaling controller 3 which is not directly connected to the direct neural interface 2 but via a wired or wireless communication network 6. In particular, either the vehicle of the first road user 5v, or a smartphone of the first road user 5s (not shown), etc. comprises the controller 3 and communicates with the direct neural interface 2 via a wireless network such as Bluetooth TM , Wifi TM , Lora TM , etc.

[0158] Thus, the invention proposes to trigger the flashing lights of the signaling on the helmet or vest using a controller based on the brain signals (EEG) of the cyclist, in particular based on analyzing these brain signals. Several stimuli, in particular auditory stimuli, are presented to the user. They are differentiated, for example, by their frequency. Each stimulus is associated with a different indicator. The user focuses on the stimulus corresponding to the indicator he wishes to trigger (for example, flashing right). By observing the brain signals (EEG) of the user, it is possible to identify the frequency of the stimulus on which he focuses to trigger the desired indicator.

[0159] In fact, the cyclist is equipped with a bicycle helmet in which a direct neural interface is attached, including electrodes for observing his brain activity, and possibly a bone conduction headset and / or a vest. The bone conduction headset can reproduce, for example, sounds at different frequencies and different locations (right, left, in front, behind) without cutting the cyclist off from surrounding noise.

[0160] So, when the user focuses on the sound located on the right, it is possible to find the frequency on which he is focusing by analyzing his brain signals, and thus trigger the right indicator on his helmet or vest. The same is true for a sound located on the left. Sounds located in front or behind can trigger other actions such as turning on a brake light or hazard lights.

[0161] The cyclist no longer needs to take one hand off the handlebars to indicate the direction he wishes to take. His change of direction is indicated on his helmet or vest for significantly improved visibility for other road users.

[0162] The invention also relates to a medium. The information medium may be any entity or device capable of storing the program. For example, the medium may comprise a storage means, such as a ROM, for example a CD ROM or a microelectronic circuit ROM or a magnetic recording means, for example a floppy disk or a hard disk.

[0163] On the other hand, the information medium may be a transmissible medium such as an electrical or optical signal which may be conveyed via an electrical or optical cable, by radio or by other means. The program according to the invention may in particular be downloaded from a network, in particular of the Internet type.

[0164] Alternatively, the information carrier may be an integrated circuit in which the program is incorporated, the circuit being adapted to perform or to be used in the performance of the method in question.

[0165] In another implementation, the invention is implemented by means of software and / or hardware components. In this regard, the term module can correspond to either a software component or a hardware component. A software component corresponds to one or more computer programs, one or more sub-programs of a program, or more generally to any element of a program or software capable of implementing a function or a set of functions according to the description above. A hardware component corresponds to any element of a hardware assembly capable of implementing a function or a set of functions.
