The invention relates to a method for characterising the ocular activity of a person, using at least two electroencephalographic signals, each signal being delivered by an electrode positioned on the scalp of the person, comprising the steps of: - separation of the electroencephalographic signals into a plurality of sources of origin, said signals being modelled as a mixture of components each corresponding to a cerebral source of origin or to an artefactual source of origin - identification and selection of at least one artefactual ocular source of origin among the separated sources, characterised in that it comprises a step of reconstructing at least one electro-encephalographic signal corresponding to said at least one selected artefactual ocular source of origin, and a step of determining information relating to ocular blinking using a reconstructed electroencephalographic signal.
