How to decode an individual's visual interest from EEG signals

摘要

A method for determining the focus of an individual's visual interest from EEG signals. At least one visual stimulus to be displayed is generated from at least one graphic object (411), and the visual stimulus is an animated graphic object obtained by applying a temporal sequence of basic transformations temporally parameterized by a corresponding modulated signal to the graphic object. to be. From a plurality of EEG signals generated by an individual focusing his visual attention on one of the visual stimuli, a modulated signal is reconstructed (414). A visual stimulus corresponding to a modulated signal whose statistical dependence on the reconstructed modulated signal is higher than a first threshold is identified (415).
