Title (EN) DECODING THE VISUAL ATTENTION OF AN INDIVIDUAL FROM ELECTROENCEPHALOGRAPHIC SIGNALS
(FR) DECODAGE DE L'ATTENTION VISUELLE D'UN INDIVIDU A PARTIR DE SIGNAUX ELECTROENCEPHALOGRAPHIQUES
Abstract:
(EN) A method for determining the focusing of the visual attention of an individual from electroencephalographic signals. At least one visual stimulus to be displayed is generated (411) from at least one graphic object, a visual stimulus being an animated graphic object obtained by applying, to a graphic object, a time sequence of elementary transformations temporally parameterised by a corresponding modulation signal. A modulation signal is reconstructed (414) from a plurality of electroencephalographic signals produced by the individual focusing his visual attention on one of the visual stimuli. A visual stimulus corresponding to the modulation signal is identified (415), for which the degree of statistical dependence with the reconstructed modulation signal is greater than a first threshold.
(FR) Procédé de détermination de la focalisation de l'attention visuelle d'un individu à partir de signaux électroencéphalographiques. Au moins un stimulus visuel à afficher est généré (411) à partir d'au moins un objet graphique, un stimulus visuel étant un objet graphique animé obtenu par application à un objet graphique d'une séquence temporelle de transformations élémentaires paramétrée temporellement par un signal de modulation correspondant. A partir d'une pluralité de signaux électroencéphalographiques produits par l'individu focalisant son attention visuelle vers l'un des stimuli visuels, est reconstruit (414) un signal de modulation. On identifie (415) un stimulus visuel correspondant au signal de modulation pour lequel le degré de dépendance statistique avec le signal de modulation reconstruit est supérieur à un premier seuil.
