METHOD OF SELECTING INDIVIDUALS BY RESOLUTION OF VISUAL EVENTS IN TIME Russian patent published in 2018 - IPC A61B5/16 A61B3/02 

FIELD: medicine.

SUBSTANCE: invention relates to medicine and medical technology and is intended for selection of persons for activities requiring a good resolution of visual events in time limited by the inertia of vision, and can find application in aerospace, transport and sports practice. On the subject, a wearable device is fixed: a helmet, glasses or lenses forming an augmented reality that is part of the hardware and software complex. Device that generates augmented reality is fed with pairs of light pulses, a reference length of 80 ms and adjustable in duration, repeating through a time interval of 1 s. Pulse that is adjustable in duration is delayed or terminated earlier relative to the time of presentation of the reference pulse. In the first stage of measurements, the delay time or early end of the pulse regulated with respect to the pulse duration relative to the reference one is increased at each subsequent presentation discretely with a constant step of 0.5 ms, Subject will not determine the moment of sensation that the light pulses begin or end not simultaneously. In the second stage of measurements, the delay time or early end of a pulse that is adjustable in duration is reduced with each subsequent presentation discretely with a constant step of 0.1 ms, subject will not determine the moment of sensation that the light pulses begin or end simultaneously. Delay or early termination of a pulse that is adjustable in duration relative to the reference pulse at the moment of sensation that the light pulses begin or end simultaneously are fixed. Time of inertia of the visual system is assumed to be equal to the value of the delay time or the time of the early end of the light pulse regulated with respect to the duration relative to the reference one recorded at the second stage of the measurements. Method allows to expand the conditions for determining the time of inertia of the human visual system, ensure selection of persons for activities that require a good resolution of visual events in time by determining the inertia of the visual system while simultaneously presenting two light stimuli and the use of a wearable device that forms augmented reality. Selection of subjects is performed at the least time of inertia, which determines the best resolving power of visual events in time.

EFFECT: claimed method allows to expand conditions for determining the time of inertia of the human visual system, to perform selection of persons for activities that require a good resolution of visual events in time.
