摘要：The invention relates to a method for evaluating and/or improving dynamicvisual perception of an individual, comprising: a) displaying on a screen (11) a movingpattern (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 thepattern that the individual sees on the screen, c) repeating the preceding steps in orderto count the number of successive positive answers imputed at step b), and d1) if thenumber 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) repeatingsteps 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 complexityfeature (Simp) of patterns that the individual can identify. This maximum visual complexityfeature defines a quantitative value of the dynamic visual perception of the individual.
