Typography for low vision.

So here is a new a post relating to my idea about information design for the blind or low vision people.  AIGA has an article about typography guidelines for signage that is accessible to the aging eye.  It deals specifically with people with blurry vision and loss of peripheral vision.  It explains why some typefaces are better than others.

The font below is from the American Printing House for the Blind.  It was developed specifically to be read by people with vision problems. It has consistent spacing and stroke width.  It also has under-slug "j" and "q" and large punctuation marks.  They go on to say that it is not particularly pretty to look at but it is a start in the design field to start accommodating the aging eye and people with other visual obstructions.

The following fonts show the difference between a san serif font and a serif font when simulated with blurry vision.  (The top two are Bodoni and Times Roman.  The bottom two are Frutiger Bold and Syntax Bold)
