METHOD OF DETERMINING STATE OF HUMAN OPERATOR

摘要

FIELD: medicine.SUBSTANCE: invention relates to field of medicine, namely to methods of determining state of human operator. Tested person, who is in rested and tired states, is shown signals of alternating frequency, formed in form of solutionrequiring tests, the number of which is set equal for rested and tired states, indices of tested person's response to shown signals are measured. After carrying out n tests, representative time of correct solution of one test in rested state is determined in correspondence with the formula Trr=(Tav.r+Tav.r+Tav.r++?+Tav.r)/n, where Trr is representative time of correct solution of one test in rested state, Tav.r is the average time of correct solution of one test in rested state, 1, 2, 3,. ?n are sequence numbers of carried out tests, n is the quantity of carried out tests. Assessment of state of human operator further is carried out by relative change of average time of correct solution of one test in tired state in accordance with the formula (Tav.t-Trr)100%/Tav.t, where Tav.t is the average time of correct solution of one test in tired state.EFFECT: method makes it possible to assess state of human operator by degree of their mental fatigue in accurate and reliable way and predict change of professional indices of operators.
