Title
(EN) METHOD AND SYTEM FOR GENERATING A PERSONALIZED PLAYLIST OF SOUNDS
(FR) PROCÉDÉ ET SYSTÈME POUR GÉNÉRER UNE LISTE D’ÉCOUTE PERSONNALISÉE DE SONS
Abstract
(EN)
The present invention relates to a method for generating for a subject a personalized playlist of sounds (P), notably songs, using the analysis of the subject's electroencephalographic signal, said method comprising the following steps: receiving (M10) at least one segment of electroencephalographic signal (S) acquired from at least one electrode while the subject is listening to at least one proposed sound; extracting (M20) at least one EEG index (Id) from the el ectroencephalographic signal segment (S) so as to characterize brain patterns correlated to the emotions evoked by the music and the level of appreciation of the sound; evaluating (M30) the valence of sounds listening (V) on the basis of the EEG index (Id); receiving (M40) a score of appreciation (Sc) on the sound from the subject; including (M50) the sound in the personalized playlist (P) of the subject whenever the valence matches a predefined valence and/or the score of appreciation is higher than a predefined threshold.
(FR)
La présente invention concerne un procédé pour générer, pour un sujet, une liste d'écoute personnalisée de sons (P), notamment des chansons, à l'aide de l'analyse du signal électro-encéphalographique du sujet, ledit procédé consistant à : recevoir (M10) au moins un segment de signal électro-encéphalographique (S) acquis à partir d'au moins une électrode pendant que le sujet écoute au moins un son proposé ; extraire (M20) au moins un indice (Id) d'électro-encéphalogramme (EEG) à partir du segment de signal électro-encéphalographique (S) de façon à caractériser des motifs cérébraux mis en corrélation avec les émotions évoquées par la musique et le niveau d'appréciation du son ; évaluer (M30) la valence d'écoute de sons (V) sur la base de l'indice (Id) EEG ; recevoir (M40) un score d'appréciation (Sc) sur le son à partir du sujet ; inclure (M50) le son dans la liste d'écoute personnalisée (P) du sujet à chaque fois que la valence correspond à une valence prédéfinie et/ou que le score d'appréciation est supérieur à un seuil prédéfini.
