Does This Font Truly Help Dyslexic Readers to Read?
Dyslexia is a perceptual problem where the brain rotates and misinterprets visual information, and affects about 10% of the population. By analyzing HOW the dyslexic brain confuses printed letters, and then making subtle changes to confound that process, Abelardo Gonzalez, creator of the new (free) Open Dyslexic typeface, hopes to increase reading ability in dyslexic readers.
Excerpt: "Your brain can sometimes do funny things to letters. OpenDyslexic tries to help prevent some of these things from happening. Letters have heavy weighted bottoms to add a kind of "gravity" to each letter, helping to keep your brain from rotating them around in ways that can make them look like other letters. Consistently weighted bottoms can also help reinforce the line of text. The unique shapes of each letter can help prevent flipping and swapping.
OpenDyslexic also takes a different approach to italic styles. It is generally recommended that italics be avoided in reading material for dyslexia. However, instead of taking the normal approach of 'slant x% for italic,' OpenDyslexic's italic style has been crafted to allow for its use for emphasis while maintaining readability."
