FIELD: medicine.

SUBSTANCE: invention refers to medicine and aims at assessing and developing hand-eye coordination of a human operator. Disclosed is a method in which a PAC is formed, a person being tested is presented on a screen for test movement of a CO of a given size and shape, as well as a given number of MOs of a given size and shape, which are moved along the screen of the person being tested in programmed straight-line sections at a given speed. Person being tested, observing MO displacements, identifies the regularity of their displacement and transfers the CO to places free from MO routes, avoiding collisions with the MO and the boundaries of the CO coverage area. Person being tested moves the CO on the field of the monitor with the help of a joystick. Size, shape of the CO action zone, as well as the CO size, quantity, speed, size, colour, contrast and nature of MO movement are used to form the level of cognitive-motor load in each test or developmental exercise. Parameters and characteristics of the coverage area of the CO, the CO and MO themselves are selected from the HSC library or are entered into the HSC by the researcher taking into account the preparedness of the person being tested. At moments of collision of CO with MO or boundary of CO coverage area the error of the person being tested is fixed, and the specified sound or light signal is sent. Test is repeated for a given number of times with breaks of a given duration. Time to collision with MO or CO coverage area boundary in all tests is automatically fixed by HSC for data analysis and calculation of arithmetic mean value of measured value in specified conditions. Feature of the method is that the mobile objects and the controlled object are visualized on the field of action of the person being tested using virtual reality means, which are fixed on the person being tested. Observation and control over the actions of the person being tested is carried out through external monitors of the software and hardware complex, which synchronously display the video content presented to the person being tested. Virtual reality video content is supplemented with a given mobile or stationary background image. Preset HSC program forms a cognitive load of the test or exercise, the load value is controlled by changing the contrast and brightness of the mobile objects, the controlled object, as well as by changing the contrast and brightness of the given background image with given characteristics of its movement. Arithmetic mean value of the time of error-free control of the controlled object is calculated in the given test conditions with different versions of the cognitive-motor load, and the level of hand-eye coordination of the person being tested is determined from the value.

EFFECT: proposed method enables to obtain quantitative data that were previously unavailable for specialists.
