METHOD FOR HUMAN VISION SYSTEM RESPONSE TIME DEFINITION Russian patent published in 2017 - IPC A61B5/16 

FIELD: medicine.

SUBSTANCE: wearable augmented reality forming device is attached to the subject, which is part of the research software and hardware complex. The researcher chooses a mode of motor or exercise test from the complex program library and introduces it to the subject. Then, pairs of light pulses, reference one with duration of 80 ms, and one adjustable in duration, repeating in a time interval of 1 s, are supplied to the augmented reality forming device. The duration-adjustable pulse is delayed or terminated earlier relative to the time of the reference pulse initiation. At the first stage of measurements, time of delay or early termination of duration-adjustable pulse relative to the reference one is increased discretely with a set constant pitch of 0.5 ms, until the tested person determines the moment of feeling that light pulses start or end in a staggered manner. At the second stage of measurements, time of delay or early termination of duration-adjustable pulse relative to the reference one is reduced discretely with a set constant pitch of 0.1 ms, until the tested person determines the moment of feeling that light pulses start or end simultaneously. Delay or early termination of the duration-adjustable pulse relative to the reference one at the moment of sensation that the light pulses begin or end simultaneously is recorded. Time of visual system inertia is accepted as equal to the time of delay or time of early termination of the duration-adjustable light pulse relative to the reference one, recorded at the second stage of measurement. Further, during motor or exercise test execution under stationary conditions or at ground, water or flight movements, the subject periodically receives light pulses with a predetermined period, with the last recorded delay time or early termination time of the duration-adjustable light pulse relative to the reference one. If the subject feels that the light pulses begin or end at the same time, the delay time or the early termination time of the duration-adjustable light pulse relative to the reference one is increased with each subsequent presentation discretely with a predetermined constant pitch of 0.1 ms, until the subject determines the moment of sensation that the light pulses start or end in a staggered manner. Delay or early termination of the duration-adjustable light pulse relative to the reference one at the moment of sensation that the light pulses begin or end in a staggered manner is recorded. If the subject feels that the light pulses begin or end not in the staggered manner, the delay time or the early termination time of the duration-adjustable light pulse relative to the reference one is reduced with each subsequent presentation discretely with a predetermined constant pitch of 0.1 ms, until the subject determines the moment of sensation that the light Impulses begin or end simultaneously. Delay or early termination of the duration-adjustable light pulse relative to the reference one at the moment of sensation that the light pulses begin or end simultaneously is recorded. Delay or early termination time of the duration-adjustable light pulse relative to the reference one is recorded according to the conditional actions or signals of the subject, which are captured by the software and hardware complex or by the researcher. When the subject is removed to a considerable distance from the researcher, communication and information exchange is carried out via radio channel.

EFFECT: method allows to determine the time of inertia due to motor or exercise tests under the conditions of augmented reality.
