By now you have probably heard the joke about the dyslexic agnostic who was also an insomniac. He would lie awake nights wondering if there was a dog. Dyslexia is the tendency to rotate, mirror, swap and reverse letters and numerals. Once in a while you might write 96 instead of 69, for example. For some people this tendency to mix up letters can be so bad it interferes with their ability to decipher written text.
I recently ran into an article about a font designed to demphasize the symmetry of our letters to make them easier to distinguish. I don’t know if the font works as intended, but the concept is interesting.
Here’s a diagram of a couple letters to give you the idea. The Scientific American article goes into greater detail, and has more pictures. Go take a look.
