Abstract

A method for evaluating and/or improving dynamic visual perception of an individual, comprising: a) displaying on a screen (11) a moving pattern (12) having a chosen visual complexity feature (Simp), b) providing a human/machine interface (13, 14) enabling the individual to input a value to indicate the pattern that the individual sees on the screen, c) repeating the preceding steps in order to count the number of successive positive answers imputed at step b), and d1) if the number of successive positive comparisons exceeds a predetermined threshold (S1), increasing (S2) the pattern visual complexity feature of a chosen amount, d2) otherwise, lowering (S7) the pattern visual complexity feature of a chosen amount, e) repeating steps d1) and d2) and lowering (Appl h, S3; S8) the chosen amount each time an alternation between steps d1) and d2) is detected, until a predetermined number (THR) of alternations (Alter) is detected, in order to determine a maximum visual complexity feature (Simp) of patterns that the individual can identify. This maximum visual complexity feature defines a quantitative value of the dynamic visual perception of the individual.
