Method for improving the reading of graphical and text content

1. Method for improving the reading of a graphical content or a text content by a person subject to dyslexia, by displaying and inhibiting periodically said graphical content in a content playback device (DISP),

wherein said method comprises: an alternation of display periods, during which all or a portion of the graphical content is displayed, and periods of absence of display, during which the graphical content is not displayed, according to successive cycles that take place at a predetermined frequency Fd,

wherein each cycle has a duration (T) and comprises a display period of duration (T1) followed or preceded by a non-display period of duration (T2), said frequency (Fd) being defined by the relationship Fd=1/(T1+T2),

and in that the duration (T1) is comprised in an interval of values ranging from 15 to 30% of the duration (T) of said cycles, and

in that the frequency (Fd) is comprised in an interval of values ranging from 60 to 90 Hz.

2. Method according to claim 1 , wherein the frequency of the signal is equal to 70 Hz or 84 Hz and the duty cycle T1/(T1+T2) is equal to 20%.

3. Method according to claim 1 , wherein the frequency (Fd) varies over time.

4. Method according to claim 3 , wherein the predetermined frequency (Fd) is said to be wobbling taking advantage of the Hebbian mechanisms of the neurons of the cortex and varies by increasing in successive steps to a maximum value according to a first speed, referred to as the increase speed, then varies by decreasing in successive steps to a minimum value according to a second speed, referred to as the decrease speed, with the increasing and decreasing variations repeating iteratively over time.

5. Method according to claim 4 wherein said decrease speed is equal to said increase speed.

6. Method according to claim 5 , wherein said successive steps are of equal duration.

7. Method according to claim 5 , wherein said successive steps vary in duration in such a way that the value of said frequency (Fd) changes according to a triangle, saw-tooth or sinusoid waveform between said maximum value and said minimum value.

8. Method according to claim 1 , wherein the duration (T1) of said display periods varies over time.

9. Method according to claim 1 , wherein said display device is included in the list: playback screen, computer, tablet, touch tablet, telephone, smartphone, smart watch, digital book, guide or device for assistance in the circulation of vehicles or of pedestrians.

10. Method according to claim 1 , wherein said predetermined frequency (Fd) is defined by a user.
