Method for noninvasive diagnosis of functional state disorders in operators with the smooth pursuit test

Abstract

The article describes a videooculographic method to detect functional state disorders in operators in the target tracking test. The method is an improved version of the smooth pursuit test and can be used to detect and to estimate the effects of various adverse factors on operators in laboratory experiments. The method is noninvasive, allows a continuous data recording for a long period of time with the subject in comfortable conditions, and may employ various videooculographic devices (including portable and low-cost models). As an example, a series of experiments was performed to detect the negative effects of alcohol intoxication. A linear relationship was observed between changes in parameters of oculomotor reactions and changes in reaction time to the target stimulus.
