00:00In the industry of cosmetics, defense, entertainment, they arrive here to experiment you somewhere, you analyze.
00:11We receive here the CEO of Mentalista, Bastien Didier.
00:16It's for him!
00:19Hello!
00:20How are you?
00:20Thank you!
00:22Hello everyone!
00:24I'm Bastien Didier, I'm the founder of a company called Mentalista.
00:28Chez Mentalista, on fabrique des captures to measure the brain.
00:34For example, today we're going to do a demonstration, we're going to create things by the thought.
00:39You'll discover it later.
00:41We're going to spend 20 minutes together.
00:43I'm not going to create something without explaining how it works.
00:48What we need to know about Mentalista is that we want to put neurotechnologies everywhere.
00:54That's why we have this title, neurotech everywhere, which means neurotechnologies partout.
01:01Chez Mentalista, as I said, on fabrique des captures that measure the brain.
01:05Because we think that the brain will become a new interface with the world around us.
01:10In this moment, many of you are taking photos.
01:13For taking photos, you can use your pouce or index and you're going to press on a button.
01:18You're going to agree that it's very surpassed, now, to do that.
01:21And we want to evolve, still.
01:23So, we're going to say that we could simply use our brain activity.
01:27We're going to say that we're going to take a picture and take a picture.
01:31And we're going to be in a world that will become more and more connected.
01:33We've seen probably here at Meta, the lunettes are connected.
01:36You'll have just thought, and the lunettes will take a photo, a video.
01:40And all that will go very quickly.
01:42What is very important is that we think about neurotechnologies
01:46will not be a new tool that you are going to wear on your head.
01:49They are basically the accessories you wear.
01:52I see the lunettes, I see the casquettes.
01:54Probably some of them already have in the pocket.
01:57Some of them have already been in the pocket.
01:58All of these are tools that will be able to integrate
02:01and measure what happens in your brain
02:04to be useful in terms of interaction.
02:10So at Mentalista, what we do very precisely is
02:13we fabricate a specific product called Mental Clip
02:17and there is a name as distinct, which is the clip
02:20because it allows you to clip a little bit.
02:23We will be able to clip in all types of objects
02:25to make them intelligent and be able to measure
02:28what happens in your body, in your brain and in your environment.
02:32This clip has 9 replacements
02:35in which we will be able to put a number of captures
02:37and we will be able to put a number of captures
02:40that you don't imagine even possible today.
02:42We will be able to analyze your sueur,
02:44analyze the oxygen of your sang,
02:46your pulsations cardiaques, the temperature of your peat,
02:48analyze the prosody, what you are saying,
02:50analyze the environment with cameras.
02:53In the meantime, it is a series of captures
02:55that allows you to understand what happens around us.
02:59What I propose is that
03:02I will just explain
03:03that at Mentalista,
03:05in reality, we do not distribute to the public
03:07today.
03:08So you will not be able to go to the FNAC
03:10or Darty or online
03:11to be able to purchase this kind of technology.
03:13We distribute mainly
03:15to companies who use it
03:17in a very varied context
03:20and there you have a few examples
03:21of how it can be integrated.
03:23In the case of a policeman
03:24to do a life
03:25to do a life
03:25to do a life
03:26to do a person
03:28on an operator
03:29to measure
03:30its charge cognitive
03:31and stress
03:32in real time
03:32and prevent
03:34from accidents
03:35before they arrive.
03:36The casquette
03:37for many other uses,
03:38the gaming,
03:38the XR,
03:39the defense.
03:42So, as I said,
03:43what I propose
03:44is to show you a little bit
03:45how it works.
03:46First,
03:46I'm going to show you
03:48I'm going to show you
03:49I'm going to show you
03:51I'm going to show you
03:52and I'm going to show you
03:53The port is also simple
03:54that this.
03:55I'm going to position you
03:56there.
03:57There's a silicone band
03:58just to the front
03:58which will come to my front
04:01and will measure
04:03what's happening
04:03in my brain.
04:04We're going to connect
04:05and it's connected
04:05to the Bluetooth.
04:08There's a little bit
04:09of stress
04:10because we don't know
04:11if the connection
04:12will work.
04:12and we're going to measure
04:14here in real
04:15three information
04:17about my mental state.
04:19The cognitive load,
04:20so the cognitive load,
04:22which means
04:22how much I'm engaged
04:24in terms of
04:25action cognitive.
04:26There,
04:27I don't do anything
04:27very complicated.
04:28I only do that.
04:28It's a simple task.
04:30So, my cognitive load
04:31is not supposed to be very high.
04:33We measure also my attention.
04:35So, my attention
04:35is typically
04:36the moment where I put
04:37my gaze on someone
04:38and focus on something
04:40and focus on something
04:41on something
04:42my attention
04:43will increase.
04:44And as I move
04:45and look ailleurs,
04:46it will descend.
04:47And finally,
04:48we measure also
04:49my emotions.
04:50So, my emotions,
04:50it doesn't mean
04:51to measure
04:51if I'm happy
04:52or if I'm happy.
04:54It's not as binaire
04:55as that.
04:56We measure what we call
04:57the valence
04:58and the rose hole.
04:58So, in fact,
04:59is that the experience
04:59that I'm experiencing
05:00is positive or negative?
05:02Is that I'm more or less relaxed?
05:04I'm very excited.
05:05And with these two information
05:07we'll combine
05:07and combine
05:08together
05:09to be able to
05:10describe
05:10if I'm in a mood
05:12more joyous
05:13or more triste
05:14or different things.
05:16So, you'll be able
05:17to see these information
05:18all along
05:19the presentation
05:20in the little encart
05:21in the bottom
05:22to the left.
05:22And now,
05:23I'll just show you
05:24some examples
05:25of what we're doing
05:26today with.
05:28So, we're doing
05:29a lot of things
05:29that are liable
05:30to the hyper-personnalization
05:31in the store.
05:32For example,
05:33it's distributed
05:33by the Cosmetics Sisley.
05:35Maybe some of you
05:36are found
05:37at the Sephora
05:38of Champs-Elysées
05:39and have,
05:40on the stand
05:42of Sisley,
05:43had one of our cases
05:44on the head
05:44to measure the impact
05:46cognitive
05:46of their cosmetics
05:47on your cerveau.
05:49Our cases
05:50and our capters
05:51are also used
05:51for all the
05:52consumer studies.
05:54So, all the brands
05:55who create
05:55new cosmetics,
05:56new products,
05:58new vêtements,
05:59new equipment,
06:00to measure
06:01what's happening
06:02at the moment
06:03of interaction,
06:04at the moment
06:04of the goût,
06:05at the moment
06:05of the olfaction
06:06on the different products
06:08to determine
06:09if one formula
06:10is more pleasant
06:11than the other.
06:12It's also used
06:14in the products
06:15to come,
06:15in all the diagnostics
06:17connected to the skin care.
06:18I'm sure
06:19if some of you
06:20know
06:20the masks LED,
06:22the electro-stimulation
06:24which are used
06:25with the cream
06:25today,
06:27tomorrow,
06:27these tools
06:28will become intelligent
06:30to measure
06:30what's happening
06:31in your body
06:31to adapt
06:32in real time
06:33and provide a stimulation
06:34that will be adapted
06:36to your needs
06:37physiologically.
06:39Finally,
06:39we work a lot
06:40in the world
06:40of security
06:41and defense.
06:42For example,
06:44for the future
06:44soldier
06:46embarked
06:46of the French
06:47our captors
06:48to measure
06:49its charge
06:50in real time
06:51to prevent
06:52the accident,
06:53inform the doctor
06:54in case of an accident
06:55and provide
06:56information in front.
06:57It's a tool
06:58that is there
06:59to save lives.
07:00We also do
07:00a lot of things
07:11to know
07:12if it was wrong
07:13if it was too charged
07:15if it was too charged
07:15if it was able
07:15to apprehend
07:16this information.
07:17Today,
07:19there are lots
07:19of accidents
07:20who are liés
07:20to this cognitive charge
07:23and we will have
07:24tools that allow
07:25to measure
07:26and allow
07:27the machine
07:27to take the hand
07:28if there is
07:30a failure
07:30and finally,
07:31the maintenance
07:32of the operability.
07:34The same thing,
07:35there are many operators
07:35who are on the terrain
07:36during a period
07:37that are very short.
07:38They will return
07:39in casernes,
07:40they will return
07:40to each other
07:41in different situations.
07:42We need to know
07:43if they are still
07:43at the top
07:45of their mental performance
07:46and these tools
07:47are exactly
07:48for that.
07:50So,
07:50what we do
07:52very quickly
07:53is that
07:54we have 4
07:55couches
07:56in our ecosystem.
07:57First,
07:57we fabricate
07:58components,
07:58semi-conductors,
07:59like those
08:01that there are
08:01in your phone.
08:02We assemble them
08:04in the case
08:04to measure the information.
08:06Then,
08:06we have the development
08:07that allows our clients
08:08to create applications.
08:10When you go to an application
08:11on your phone,
08:12it is developed
08:12with a code informatic.
08:14We have a code informatic
08:15that allows
08:16to understand
08:16what's happening.
08:19So,
08:19it is a bit more
08:20for the public.
08:21We call it an application
08:25programming interface,
08:26it is to say
08:26an interface
08:27of programming
08:28that will allow
08:28to speak with an online service
08:30to provide information.
08:32So,
08:32it means that
08:33we will recover
08:34the information
08:41in the case.
08:49So,
08:50it is an information
08:56in the case.
08:57that we need
08:57to recover
08:58emotional information
08:59from the case.
09:00So,
09:01we can already
09:03create an interaction
09:05with it.
09:06So,
09:07as you saw,
09:09today,
09:09we distribute
09:10three models,
09:10emotion,
09:11cognitive
09:11and attention.
09:12and we will
09:13distribute
09:13a new model
09:14which will
09:15make sense for you.
09:15So,
09:16it is a model
09:16of authentication.
09:17So,
09:20today,
09:20it is not very interesting
09:21for us,
09:21but for example,
09:22you have people
09:23who already
09:26want to pay,
09:26for example.
09:27Today,
09:28they cannot pay
09:28all the money,
09:29because they don't have
09:29the money,
09:30probably the motor,
09:31they will pass
09:32by a third person.
09:33So,
09:34typically,
09:34we have a bank clients
09:35who are interested
09:36to how these people
09:38are going to identify
09:40and allow them
09:41to make payments
09:42by the pensée.
09:42That's what this model
09:43will do.
09:46And finally,
09:47the most important,
09:47because I know
09:48that you all have to ask
09:48this question,
09:50the cerebral data,
09:51it is obviously
09:52extremely important,
09:54extremely precious,
09:55because it gives
09:55so much information
09:56about us,
09:57and it is very important
09:58that it is anonyme,
09:59that it is secure,
10:00and that it is always private.
10:02Today,
10:02when we do this
10:03emotional analysis,
10:05for example,
10:06everything is on the machine.
10:07We are not connected
10:08to the internet,
10:09everything is calculated
10:10directly in the casque,
10:11it is shared just
10:12at a key moment
10:12to provide information,
10:14and after,
10:15the information,
10:15it is never shared.
10:16And it is really important
10:17to ensure,
10:19in the future,
10:20to be always compliant
10:21with the law,
10:22with the RGPD
10:23and with all the evolutions
10:24that will be available
10:25on the bioethics,
10:26etc.
10:27So,
10:28I gave you a first overview
10:29of what are the neurotech
10:30and what they are for us
10:31to show you
10:32how much it is present
10:34in the lives
10:34of many people.
10:36We have been using
10:38for about a million
10:38sessions in 2025.
10:40Today,
10:41we have at least
10:41300 platforms
10:42who are active
10:43for our clients.
10:44A platform,
10:45that means
10:45that it is a complete
10:46set of parks
10:48that will be deployed
10:49for a specific usage.
10:50And there,
10:51we are very proud
10:52that all of this
10:53is designed
10:54and entirely
10:55made in France.
10:57Everything is done
10:58at Paris,
10:59all the components,
11:01the electrodes,
11:02the assemblage,
11:02everything is done here
11:03for sure
11:04that we are always
11:06proprietors
11:06of what we have
11:07and it is very important
11:08that we develop
11:08this kind of technology.
11:10So,
11:11we are distributed
11:12everywhere.
11:13That's great.
11:14And what I propose now,
11:15is to test it.
11:17For testing
11:18this interface,
11:19there are some of you
11:20who will be able
11:20to put it on their heads
11:22and who will create
11:24a fleur
11:25by the thought.
11:25And for that,
11:26I will welcome Gregory,
11:28who is one of our real clients,
11:30who will show you
11:31how he uses
11:32our capters
11:34to create
11:35interfaces
11:35that allow the public
11:37to create
11:38by the thought.
11:39Gregory?
11:45Hello everyone,
11:46thank you.
11:48I have answered
11:48to the invitation
11:50of Bastien
11:50because I am co-founding
11:52and I lead Science Experience
11:53which is an immersive
11:55museum museum
11:55of science.
11:56I don't know
11:57if there are
11:58who know Science Experience
11:59in the room?
12:02Some of us,
12:03but not many.
12:04Science Experience
12:05in two words,
12:06it is an immersive museum
12:07of science.
12:07And so,
12:08we make an experience
12:09to people
12:10and then,
12:11we explain the knowledge
12:13associated with it.
12:14And so,
12:15it's a journey
12:16that's one hour and a half,
12:17we travel in space,
12:18we end up with the abyss,
12:20we explain,
12:21for example,
12:21what happens to be
12:22from 0 to 11.000 m
12:23below the sea.
12:24What else do we do?
12:25We travel to the center
12:26of the earth
12:27and we have an experience
12:28on the brain
12:29that we have co-realized
12:31or co-customized,
12:33I would say
12:33with Bastien
12:35and with Mentalista
12:36or we will make
12:37the world
12:38or not
12:39on the public?
12:40Romain,
12:40I'm in trouble.
12:41Okay,
12:42don't hesitate
12:42to put the
12:44on your head
12:45on your head.
12:47It's not a problem.
12:48Don't worry,
12:50there are many
12:51who can test it?
12:53There are many
12:56who want to test it?
12:57There are
12:57there are
12:57there are
12:58there are
12:59there are
13:00one by one.
13:02One by one,
13:03for info,
13:04when you come to Science Experience
13:05we can do it by
13:0625 people
13:07and you can do it
13:08at Paris-Bercy,
13:09you can do it
13:10at Lyon
13:10or you can do it
13:12because we have
13:13700.000 visitors
13:14since the opening
13:14in 2021
13:15and we are present
13:16at Paris-Bercy
13:17we are present
13:17at Lyon
13:18we are present
13:18at Bordeaux
13:19and the fourth
13:20at Paris
13:21in the 17th arrondissement.
13:26How is your name?
13:27Mia.
13:28Mia.
13:29Super.
13:30Mia,
13:30courage,
13:31we can applaud her.
13:35The case
13:35is a bit too big
13:36for you.
13:37Mia,
13:39it's better
13:40that people
13:40are a little bit
13:41so imagine
13:41you're in your bed
13:43you're in your bed
13:44you're in your bed
13:45you're in your bed
13:46you're in your bed
13:49you're in your bed
13:49you're in your bed
13:49and in about 2 minutes
13:52we're going to see
13:53something
13:54in any case
13:55we're going to see
13:56an illustration
13:57a fleur
13:57which represents
13:58the ideas
13:59that you've encountered
14:00okay
14:00we have different
14:01ones in the brain
14:03we have the beta
14:04we have the alpha
14:06and what is interesting
14:07also
14:07we do at Science Experience
14:09is that we demonstrate
14:09the ideas rechanges
14:10about 3 mer.
14:11so people
14:11think about
14:12how do you think
14:1680%
14:17do you think
14:18that 30%
14:19who think
14:22that is more
14:23did you think
14:24about
14:25what you think
14:27about
14:2790%
14:29how %
14:3060%
14:33so that is
14:33app for我们
14:33100%
14:34our brain
14:35we do not even
14:37in the same time.
14:38The brain, if we wanted to make an image, it's a bit like the house.
14:42We go to the kitchen, we go to the bathroom, we go to the bathroom, but not in the same
14:45time.
14:46It's the same thing with our brain.
14:47But the film of Luc Besson, Lucie, who said that we only use 10% of our brain, it's
14:51false.
14:52We use 100% of our brain.
14:54Okay?
14:57And by the way, another question,
15:00while we finish the experience,
15:02to your opinion, where do we have neurons?
15:03Where do we have neurons in the brain?
15:06Where do we have neurons in the brain?
15:12The intestine, it's yes.
15:14It's about 500 000 neurons in the intestine and the third organ where there are neurons.
15:18The what?
15:19The foie, it's no.
15:21There's no one.
15:23There's no one.
15:24The heart.
15:25There's 40 000 neurons in the heart.
15:27Who told us that?
15:29How did you know that?
15:30How did you know that?
15:30You're coming to Science Experience or not?
15:32You've done medicine?
15:35You've done medicine?
15:36I've done medicine.
15:36You've done medicine.
15:37What?
15:38Ah, well, what?
15:39Ah, well, bravo.
15:41Ah, well, you've done science experience.
15:44Yeah, we've done 40 000 euros in the heart.
15:48Well, what's the result?
15:49Well, the result?
15:50Well, the result, we've already shared.
15:51Ah, no, I'm sorry.
15:52We're going to do a second.
15:53And what's happening is that we haven't explained.
15:56So, the casque is in Bluetooth, it sends information.
15:59So, when it's ready, I'm going to launch the experience.
16:02Here, the casque is streaming.
16:04We have Catherine.
16:05Well, we'll just reconnect it.
16:07Hop.
16:08We breathe deeply.
16:11We forget that we are at VivaTech.
16:13We forget that we are at a public.
16:16So, the casque is streaming of information.
16:19Plus, normalement, on doit avoir des fleurs de couleur blanche.
16:23Vas-y, vas-y.
16:24Ou bleu.
16:26Si on a du rouge ou des couleurs foncées,
16:30ça veut dire que Catherine, elle est encore sur la scène de VivaTech.
16:34Elle n'a pas fermé les yeux.
16:35Elle ne sait pas imaginer un petit ruisseau en haut d'une montagne.
16:40Ça veut dire qu'en même temps, Bastien, tu aurais pu mettre la petite musique du ruisseau.
16:54Je pense que Catherine, elle est dans la montagne, là.
16:56Et donc là, elle est finie.
16:57Voilà la fleur, sa fleur.
16:59Et de la même façon, hop, on va vous la partager pour que tu puisses la scanner.
17:03Je peux la scanner avec vous.
17:05Ah, mais attends, on n'a pas trop trop vu, là.
17:08Je vais la remontrer après.
17:10Ok.
17:11Est-ce qu'on a un nouveau prétendant pour tester ?
17:14Allez-y.
17:15Oula !
17:16Allez-y, venez, venez, venez.
17:19C'est comment votre prénom ?
17:21Véor.
17:22Véor ?
17:23Zéor.
17:25C'est comme incertain.
17:29Et Bastien, il y a des gens aux coulisses, moi, qui me demandaient, dans les services RH, est-ce qu
17:34'on pourra mesurer le niveau de QI bientôt avec une logique de prise comme ça de neurones extérieurs ?
17:43En fait, le QI, non, parce que le QI, c'est quelque chose qui est complètement subjectif.
17:48Ici, on ne mesure que des choses qui sont très factuelles, qui vont être du signal.
17:52Du signal qui émane de notre corps et qu'on va venir récupérer et interpréter.
17:56Donc, on cherche à comprendre.
17:59Ok ?
17:59On cherche à comprendre ce qui se passe dans le corps.
18:03Non, non, il ne faut pas...
18:05Les capteurs, ils sont à l'intérieur.
18:06Donc, en vrai...
18:07Oui, oui, oui, je pense que c'est mieux de le tenir un peu.
18:13Et donc, ce qu'on fait, c'est qu'on récupère le signal en temps réel, en Bluetooth, comme je
18:17vous l'ai dit.
18:18Et on extrait ce signal, sa valence et son arrosol, donc ses émotions.
18:22Et ces émotions, en fonction de comment elles varient, on va changer la couleur, on va changer la taille des
18:27fleurs, on va changer plein de paramètres.
18:29C'est pour ça qu'à chaque fois, les fleurs sont complètement différentes.
18:32Et là, on va voir...
18:39Et là, c'est terminé. Parfait.
18:40C'est pas mal, déjà, comme arbre.
18:42Il y a des branches de partout.
18:44Il y a des pétales de partout.
18:46On est pas mal, là, zéro.
18:47Ok. On est bon.
18:55Comment ?
18:56Allez, parfait.
18:58Et de la même façon, je voulais ce QR code.
19:01Est-ce que vous avez des questions ? Est-ce que vous avez tout compris ?
19:03Oui, pour des entreprises.
19:07Tu veux tester ?
19:08Alors, si vous voulez tester, il faut aller chez Grégory à Science Experience, maintenant.
19:12Il va falloir que je rende la scène, vous imaginez bien.
19:15On fait pas de gâteaux de cadeaux, mais...
19:17Donc, vous l'avez compris, les neurotechnologies, c'est quelque chose qui est déjà très concret pour beaucoup de personnes.
19:23Un million de sessions déjà l'année dernière, un peu partout dans le monde.
19:26Des usages qui sont très variés pour de l'entertainment, pour la défense, pour le luxe, pour la cosmétique.
19:32Plein de choses qui vont évoluer.
19:34Et je vous invite à suivre ce qui va se passer dans les prochaines années, dans les prochains mois.
19:38Parce que c'est un domaine qui va énormément évoluer et sur lequel il y a plein d'innovations hyper
19:44intéressantes
19:44qui vont faire émerger plein d'usages, qui vont changer notre façon de vivre au quotidien.
19:48Merci à tous.
19:51Applaudissements
20:05Et voici pour nous, bien engagés, il nous reste une dernière séquence, mais on va se prendre un petit break.
