METHOD FOR DETECTION OF PERSEPTION TIME OF VISUAL INFORMATION Russian patent published in 2008 - IPC A61F9/00 A61B3/00 A61B5/16 

FIELD: medicine.

SUBSTANCE: using 10 light emitting diodes each of them having one of 10 corresponding buttons, testee is shown sequences of two light flashes, duration of which is 50 ms divided by a pause, repeated after constant time interval 1 s. During the fist stage of measurement sequence of two light flashes with a pause equal to 5 ms is provided to the first light emitting diode. All the following light emitting diodes are provided with sequences of two light flashes with a pause, duration whereat is increased by 5 ms compared to the pause of the previous light emitting diode. The testee detects light emitting diode with the biggest number whereat he/she subjectively perceives confluence of two light flashes into one and presses corresponding to it button. During the second stage of measurement first light emitting diode is provided with a sequence of two light flashes with a pause equal to the pause of the light emitting diode, detected by the testee during the first stage as the one, whereat he/she subjectively perceives confluence of two light flashes into one. All the following light emitting diodes are provided with sequences of two light flashes with a pause, duration whereat is increased by 0.5 ms compared to the pause of the previous light emitting diode. The testee detects light emitting diode with the biggest number whereat he/she subjectively perceives confluence of two light flashes into one, and presses corresponding to it button. During the third stage of measurement first light emitting diode is provided with a sequence of two light flashes with a pause equal to the pause of the light emitting diode, detected by the testee during the second stage as the one, whereat he/she subjectively perceived confluence of two light flashes into one. All the following light emitting diodes are provided with sequences of two light flashes with a pause, duration whereat is increased by 0.1 ms compared to the pause of the previous light emitting diode. The testee detects light emitting diode with the biggest number, whereat he/she subjectively perceives confluence of two light flashes into one, and presses corresponding to it button, registering the value of the duration of the pause. Visual information perception time by the person is assumed equal to the value of the sum of duration of the light flash and duration of the pause between two light flashes at subjective confluence of two light flashes into one during the third stage of measurements.

EFFECT: enables shortening duration of measurements and may be used for mass screening.
