I have often noticed that letters of the western alphabet look similar and are the same shape if rotated or slightly altered. Christian Boer, a graphic artist from Studio Studio created a new typeface in 2008 meant to make the individual letters more distinct and easy for dyslexic individuals to read. The University of Twente did studies and found that dyslexics reading using the dyslexie typeface actually made fewer errors. I wish I could have used the typeface for my book!
