Перспективные технологии оценки состояния человека оператора в процессе профессиональной деятельности

Abstract

Abstract: Introduction. The search for non-contact methods for assessing the functional state of a human operator in the process of professional activity is an urgent task of applied physiology. The technology for recording and analyzing physiological information based on the parameters of a person's voice can become one of the reliable and valid assessment methods. Research objective. Investigation of the possibility of non-contact voice biometrics for assessing fatigue, fatigue and / or psycho-emotional stress among operators in the course of their professional activities. Materials and methods. The study involved 14 civil aviation pilots. The pilots performed model flights on the aircraft cockpit prototyping stand with 6 different scenarios. Methods for assessing the central nervous and cardiovascular systems, the eye tracking method were used, the voice of the pilots was recorded with subsequent analysis of the parameterized voice characteristics. Research results. The state of pronounced fatigue begins to form after the 5th flight, which corresponds to the state of “functional stress”, the deterioration of the SVMR indicators relative to the background values after the 5th flight by an average of 14%, and after the 6th flight by 19% and the CVMR indicators by 19 and 26 %. An increase in the number and total duration of fixations, saccades and blinks by the 6th flight was revealed, as well as a change in the parameterized characteristics of the voice “Speech rate/pause” and “Width of the Fundamental tone peaks on the left”. Conclusions. Parametrized characteristics of human voice biometrics, which have similar dynamics with psychophysiological indicators of the state of the central nervous system, have been determined.
