Louis Braille, “Procedure for Writing Words, Music & Plainsong in Dots”, 1829 was the topic of an earlier blog post.
Here I present: William Gibson, “Pattern Recognition”, 2003. PART THREE (3).
INTRODUCTION.
PROSOPAGNOSIA (face blindness) is a disorder of “pattern recognition”. William Gibson’s protagonist-character suffers with PROSOPAGNOSIA (face blindness) and she is unable to recognize her own face. BELOW is the outline of what PROSOPAGNOSIA suffers would report as the outline is the actual face. 
COMMENTS.
Braille is a means for using dots within a “unit cell” space of “binary code” of alphabets. The Louis Braille 1829 notation system is one (1) dimensional “raised dots”. BELOW is a table of “print” and “cursive” letters. 
“Cursive lines” are not readily perceived by the blind. Raised “cursive lines” are beyond blind persons perceptions usually.
The Braille cell perception of the blind (shown BELOW) concept is a “unit cell” as an idea. The “unit cell” is recognized to represent letters (a,b,c …etcetera).
A “raised line perception is not raised dots” in PROSOPAGNOSIA (face blindness). William Gibson, “Pattern Recognition”, 2003 is about blindness other than simply absence of light as in PROSOPAGNOSIA.
