METHOD OF ESTIMATING STATE OF HUMAN OPERATOR IN SYSTEM "HUMAN - MACHINE" Russian patent published in 2013 - IPC A61B5/00 

Abstract RU 2489079 C1

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to methods of determining state of human operator in system of "human-machine". Tested person in rested and tired state is shown signals of variable frequency, formed in form of tests that require solution, the number of which is set equal for rested and tired states; parameters of tested person's response to shown signals are measured. Composed tests include part of dynamic tests, performed together by operator and machine, averaged by the number of experiments time of correct solution of one test in rested state is determined in accordance with the formula Tav=(Tav.r1+Tav.r2+Tav.r3+…+Tav.rn)/n, where T'av.r is averaged time of correct solution of one test in rested state, Tav.e is average time of correct solution of one test in rested state, 1, 2, 3, … n are ordinal numbers of performed experiments, n is the number of performed experiments. Estimation of state of human operator further is carried out by relative change of average time of correct solution of one test in tired state according to the formula (Tav.t-T'av.r) 100%/Tav.t, where Tav.t is the average time of correct solution of one test in tired state under condition of preservation of admissible accuracy and time indices of dynamic tests performance.

EFFECT: method makes it possible to estimate state of human operator more accurately and reliably by degree of its tiredness and predict change of professional indices of operators.
