Abstract : This work aims at analysing sequences of eye movements. These sequences were measured during reading tasks involving information acquisition so as to take decisions. Their analysis, based on hidden semi-Markov chains, highlights different phases of acquisition, which can be related to particular characteristics in multichannel electroencephalograms measured synchronously with eye movements during the reading tasks. This analysis reveals changes associated with the different phases of information acquisition, occurring in variances and correlations between channels at specific frequencies.
