## Bionic Reading® (BR)
This method uses visual modifications to text—highlighting partial letters—to help readers process information faster. It works because the brain recognizes words faster than the eyes can read them fully. Developed by Swiss typographer Renato Casutt, BR stems from his struggle to read Swiss-German texts visually despite understanding them auditorily.

The technology offers customization like:
– Fixation intensity (1–5 levels)
– Saccade width (10–50 levels)
– Opacity adjustments
It’s available as paid software ($4.95/year) for Windows/Mac, exporting to PDF or standard formats.
