METHOD OF EVALUATING ABILITY OF PERCEPTION OF DISTANCE AND SPACE BY HUMAN BEINGS Russian patent published in 2018 - IPC A61B5/16 A61B3/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to any area where it is required from a person to perceive and evaluate distance and space, and can find application in the physiological, medical, psychological, transport, aerospace, sports and other fields of science and practice. On a horizontal surface, two light spots are created by light emitters controlled by a computer. Examined person is placed in the middle of the line passing through the centers of the light spots. Size, direction or speed of movement of the light spots are varied according to a program over a given period of time unpredictably for the examined person. For the examined person, the area, direction and speed of movement of the light spots are changed, so the examined person changes his/her position in such a way that to remain in the middle of the line passing through the centers of the light spots. Transformation and movement of the light spots and the examined person are recorded by a video camera positioned at a given height over the horizontal surface, and the video is transmitted to the computer. Computer calculates the position of the centers of the light spots from the moment of changing the area or direction or speed of movement of the light spots periodically with a specified period; builds a line passing through the centers of the light spots; calculates the position of the center of the examined person location, the position of the point of projection of the center of the examined person location on the line passing through the centers of the light spots, the distance from the projection point to the centers of the light spots and the absolute value of their difference, distance from the center of the examined person location to the line passing through the centers of the light spots, the arithmetic mean of the absolute values of the differences in the distances from the projection point to the centers of the light spots, the arithmetic mean of the distances from the center of the examined person location to the line passing through the centers of the light spots. By the value of the arithmetic mean of the absolute values of the differences of distances from the projection point to the centers of the light spots, the ability of perception and evaluation of distance for the examined person is assessed. By the value of the arithmetic mean of the distances from the center of the examined person location to the line passing through the centers of the light spots the ability of perception and evaluation of space for the examined person is assessed.

EFFECT: method makes it possible to provide the possibility, simultaneously with the evaluation of the ability of the perception of distance, to assess the ability of perception of space through instrumental measurements.
