Des chercheurs de l’Universit\u00e9 de Tel Aviv ont d\u00e9tect\u00e9 73% des mensonges racont\u00e9s par les participants \u00e0 l’essai sur la base de la contraction de leurs muscles faciaux, atteignant un taux de d\u00e9tection plus \u00e9lev\u00e9 que toute autre m\u00e9thode connue. L’\u00e9tude a identifi\u00e9 deux groupes diff\u00e9rents de \u00ab menteurs \u00bb : ceux qui activent les muscles de leurs joues lorsqu’ils mentent et ceux qui activent leurs sourcils.<\/p>\n

Selon les chercheurs, la technologie a un grand potentiel pour d\u00e9tecter la tromperie dans des contextes r\u00e9els, tels que la s\u00e9curit\u00e9 et la criminalit\u00e9.<\/p>\n

L’\u00e9tude a \u00e9t\u00e9 men\u00e9e par une \u00e9quipe d’experts de l’Universit\u00e9 de Tel Aviv dirig\u00e9e par le professeur Yael Hanein du Centre de nanoscience et de nanotechnologie et de l’\u00c9cole de g\u00e9nie \u00e9lectrique, Iby et Aladar Fleischman Facult\u00e9 d’ing\u00e9nierie, et le professeur Dino Levy de la Coller School of La gestion. L’\u00e9quipe comprenait le Dr Anastasia Shuster, le Dr Lilach Inzelberg, le Dr Uri Ossmy et la candidate au doctorat Liz Izakon.<\/p>\n

L’article a \u00e9t\u00e9 publi\u00e9 dans la principale revue Brain and Behaviour.<\/p>\n

La nouvelle \u00e9tude a \u00e9t\u00e9 fond\u00e9e sur une innovation r\u00e9volutionnaire du laboratoire du professeur Hanein : des autocollants imprim\u00e9s sur des surfaces molles contenant des \u00e9lectrodes qui surveillent et mesurent l’activit\u00e9 des muscles et des nerfs. La technologie, d\u00e9j\u00e0 commercialis\u00e9e par X-trodes Ltd., a de nombreuses applications, telles que la surveillance du sommeil \u00e0 domicile et le diagnostic pr\u00e9coce des maladies neurologiques. Cette fois, les chercheurs ont choisi d’explorer son efficacit\u00e9 dans un domaine diff\u00e9rent : la d\u00e9tection de mensonges.<\/p>\n

Le professeur Levy explique : \u00ab De nombreuses \u00e9tudes ont montr\u00e9 qu’il est presque impossible pour nous de savoir quand quelqu’un nous ment. M\u00eame les experts, tels que les interrogateurs de la police, ne font qu’un peu mieux que le reste d’entre nous. Les d\u00e9tecteurs de mensonges existants sont si peu fiables que leurs r\u00e9sultats ne sont pas admissibles en tant que preuves devant les tribunaux \u2013 car \u00e0 peu pr\u00e8s n’importe qui peut apprendre \u00e0 contr\u00f4ler son pouls et \u00e0 tromper la machine.<\/em><\/p>\n

\u00ab\u00a0Par cons\u00e9quent, il existe un grand besoin d’une technologie d’identification de tromperie plus pr\u00e9cise. Notre \u00e9tude est bas\u00e9e sur l’hypoth\u00e8se que les muscles du visage se tordent lorsque nous mentons et que jusqu’\u00e0 pr\u00e9sent, aucune \u00e9lectrode n’a \u00e9t\u00e9 suffisamment sensible pour mesurer ces contorsions.<\/em>\u00a0\u00bb<\/p>\n

Les chercheurs ont attach\u00e9 les nouveaux autocollants avec leurs \u00e9lectrodes sp\u00e9ciales \u00e0 deux groupes de muscles du visage : les muscles des joues pr\u00e8s des l\u00e8vres et les muscles des sourcils. Les participants ont \u00e9t\u00e9 invit\u00e9s \u00e0 s’asseoir par paires face \u00e0 face, l’un portant des \u00e9couteurs \u00e0 travers lesquels les mots \u00ab\u00a0ligne\u00a0\u00bb ou \u00ab\u00a0arbre\u00a0\u00bb ont \u00e9t\u00e9 transmis. Lorsque le porteur a entendu \u00ab\u00a0ligne\u00a0\u00bb mais a dit \u00ab\u00a0arbre\u00a0\u00bb ou vice versa, il mentait manifestement, et la t\u00e2che de son partenaire \u00e9tait d’essayer de d\u00e9tecter le mensonge. Ensuite, les deux sujets ont chang\u00e9 de r\u00f4le.<\/p>\n

Comme pr\u00e9vu, les participants n’ont pas pu d\u00e9tecter les mensonges de leurs partenaires avec une quelconque signification statistique. Cependant, les signaux \u00e9lectriques d\u00e9livr\u00e9s par les \u00e9lectrodes fix\u00e9es sur leur visage ont identifi\u00e9 les mensonges \u00e0 un taux de r\u00e9ussite sans pr\u00e9c\u00e9dent.<\/p>\n

\u00ab\u00a0Comme il s’agissait d’une \u00e9tude initiale, le mensonge en lui-m\u00eame \u00e9tait tr\u00e8s simple<\/em>\u00ab\u00a0, a expliqu\u00e9 le professeur Levy. \u00ab\u00a0Habituellement, lorsque nous mentons dans la vraie vie, nous racontons une histoire plus longue, qui comprend \u00e0 la fois des \u00e9l\u00e9ments trompeurs et v\u00e9ridiques. Dans notre \u00e9tude, nous avons eu l’avantage de savoir ce que les participants ont entendu \u00e0 travers les casques, et donc aussi de savoir quand ils mentaient. Ainsi , en utilisant des techniques avanc\u00e9es d’apprentissage automatique, nous avons entra\u00een\u00e9 notre programme \u00e0 identifier des mensonges sur la base de signaux EMG (\u00e9lectromyographie) provenant des \u00e9lectrodes.<\/em><\/p>\n

\u00ab\u00a0En appliquant cette m\u00e9thode, nous avons obtenu une pr\u00e9cision de 73\u00a0% – pas parfaite, mais bien meilleure que toute technologie existante. Une autre d\u00e9couverte int\u00e9ressante est que les gens mentent \u00e0 travers diff\u00e9rents muscles du visage\u00a0: certains mentent avec leurs muscles des joues et d’autres avec leurs sourcils.\u00a0<\/em>\u00bb<\/p>\n

Les chercheurs pensent que leurs r\u00e9sultats peuvent avoir des implications dramatiques dans de nombreux domaines de notre vie. \u00c0 l’avenir, les \u00e9lectrodes pourraient devenir redondantes, avec un logiciel vid\u00e9o form\u00e9 pour identifier les mensonges en fonction des mouvements r\u00e9els des muscles du visage.<\/p>\n

Le professeur Levy pr\u00e9dit : \u00ab Dans la banque, lors des interrogatoires de police, \u00e0 l’a\u00e9roport ou lors d’entretiens d’embauche en ligne, des cam\u00e9ras haute r\u00e9solution entra\u00een\u00e9es pour identifier les mouvements des muscles du visage seront capables de distinguer les d\u00e9clarations v\u00e9ridiques des mensonges. La t\u00e2che est de terminer la phase exp\u00e9rimentale, de former nos algorithmes et de supprimer les \u00e9lectrodes. Une fois la technologie mise au point, nous nous attendons \u00e0 ce qu’elle ait des applications nombreuses et tr\u00e8s diverses<\/em>.\u00a0\u00bb<\/p>\n
