visual verbal hallucination
   Also known as logopsia, graphic hallucination, graphic speech hallucination, and visual speech hallucination. The French term hallucination verbale visuelle (i.e. visual verbal hallucination) was introduced in or shortly before 1888 by the French psychiatrist Louis Jules Ernest Séglas (1856-1939) to denote a *verbal hallucination taking the form of visually hallucinated letters, words, writing movements or hieroglyphs. Two special variants of the visual verbal hallucination are the hallucination in *braille and the *visual command hallucination.
