Since dyslexia is typically labeled a learning disability, I find it fascinating that fonts with heavier strokes on the bottom of the letters help many dyslexic people read more easily, with less page-flipping. Below is a recent example: the free OpenDyslexic font developed by mobile app designer Abelardo Gonzalez.
My research so far NLP modeling skilled readers indicates that bottom-heavy fonts help people by applying a variant of strategies good readers use to keep their eyes on the line they are reading. (My study is aimed at helping people with dyslexia. Learn more here.)
