Method and device for the predictive determination of a parameter representative of the mental activity of a person

摘要

The invention relates to the method for the predictive determination of a parameter representative of the mental activity of a person, which method involves:A) the acquisition of encephalograms of said person in the course of at least two exertion sequences separated by a rest sequence;B) the calculation in the course of each of said exertion sequences of the mean value of the dimension of a chaotic attractor, denoted df(t);C) the calculation for said exertion sequences and said rest sequence of a fatigue function F(t) and of a recovery function R(t) according to an exponential mode, with:f and r denoting a fatigue coefficient and rest coefficient respectively;D) making a prediction of the changes in the dimension d, defined by df(t)=E(t)R(t) in the course of at least two exertion sequences separated by a period of rest.
