DECODING THE VISUAL ATTENTION OF AN INDIVIDUAL FROM ELECTROENCEPHALOGRAPHIC SIGNALS

摘要

A method of determining the focus of an individual's visual attention 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 temporal sequence of elementary transformations parameterized temporally by a signal corresponding modulation. From a plurality of electroencephalographic signals produced by the individual focusing his visual attention to one of the visual stimuli, is reconstructed (414) a modulation signal. A visual stimulus corresponding to the modulation signal for which the degree of statistical dependence with the reconstructed modulation signal is greater than a first threshold is identified (415).
