FIELD: medicine.
SUBSTANCE: method applies a visual system of depth-effect 2D image perception; ocular movements are recorded by a binocular eye-tracker; right and left eye lines are sensed. At the first stage: Io image is selected, wherein the person being tested perceives image relief and depth effects. The Io is displayed on a monitor screen of the binocular eye-tracker, spaced from the eyes at 0H; a right (Ra) and left (Le) eye line X-coordinate array is recorded during the period ΔT of measurement. A coordinate difference is calculated by formula ΔX=LeX-RaX; a coordinate difference histogram is contoured; a difference histogram contour peak is localised as a peak density of eye focusing planes, a contour line range, and focusing planes. A distance maxH to the difference histogram contour peak is calculated on the left lH and right rH contour lines; provided maxH≠0H, then the differences ΔH=lH-rH are derived, and objective physiological makers of the relief effect that are the parameters independent of an estimation offered by the person being tested and recorded by the binocular eye-tracker are detected. They are compared to a relief analogue that is a 3D-pixel image perception depth 3DIo. A coordinate difference 3DΔX is calculated; a difference histogram is contoured; a difference histogram contour peak is localised as a peak density of eye focusing planes, a contour line; a distance 3DmaxH to the contour peak and the eye focusing plane, and the contour line is measured. Provided the distances 3DmaxH, 3DΔH fall within the distance range ΔH=lH-rH≠0, with maxH≠0H, general physiological principles of the relief effect perception and the depth perception of the pixel images between 3DIo and Io are stated. They are referred to reference plane images IR, which describe positions of the right and left eye focusing planes within the distance range ΔH=lH-rH≠0, with maxH≠0H. The second stage involves drawing independent samples of the people being tested who are presented with the reference plane images IR formed at the first stage. Relief build-up values are derived on the images IR, statistical relief tracking diagrams on the analysed images are constructed. The relief perception for independent samples of the people being tested is matched, and the general principles of the plane image relief perception are laid down.
EFFECT: method enables identifying the principles of unconscious perception of the image relief perception by recording the eye motions by the binocular eye-tracker.
