Via BBC Future: Dyslexie is a typeface by Christian Boer that helps dyslexics read better with asymmetrical letter forms, bold capitals, and increased length of “the up and down sticks” — ascenders and descenders — to allow differentiation and therefore better legibility.
Research conducted at the University of Twente has shown that dyslexic readers make fewer mistakes when reading text in Boer’s font, while eye tracking experiments conducted at France’s University of Lille also have shown that the gaze of dyslexics’ children flows more easily across a page of text using the font than other more traditional fonts.
Boer solved his own readability problem by designing his own typeface; now it’s available for anyone to download and use.
