Swiss typographic designer Renato Casutt has come up with an ingenious new reading system called Bionic Reading that helps you read text faster by artificially emphasizing (bolding) the first few letters of a written word and letting your brain fill in the rest.
How it works: Bionic Reading is based on the principle that our brain can identify whole words from just the initial few letters. By bolding the initial letters, fixation points are created. Your eyes glide over these points and the brain processes the rest of the word, thereby absorbing the written text faster.
People with Dyslexia and ADHD are also benefitting from Bionic Reading based on feedback received by their team and social media conversations. The method can further be adapted to the individual needs of readers by customizing the placement and opacity of the fixation points.

Just wow! The text on the right is so much easier and faster to read and understand. This blows my mind!

Extremely curious how this would perform for accessibility. i.e: dyslexiaADHD and for people who don’t quite master the language yet. Could be an interesting case study to see which user groups would benefit from this. If it works, then it could be an awesome (optional) addition

As someone who is dyslexic and likely ADHD too, I found the second one so easy to read. I started reading the one on the left and got bored instantly. It feels like this was designed for me to read quickly and efficiently. I WISH they wrote exam questions that way!

ADHD here, the right took less than half the time to read
