Abstract

L'invention porte sur un procédé destiné à mesurer les signaux d'électroencéphalogramme (EEG) d'un utilisateur. Le procédé consiste à générer un premier signal à partir d'une première électrode qui est en contact avec le cuir chevelu de l'utilisateur; à générer un second signal à partir d'une seconde électrode située à proximité de la tête de l'utilisateur sans être en contact avec la peau de l'utilisateur; et à soustraire du premier signal au moins une partie du second.
