I wonder whetherIs there a tactile tabletop flat square ridge-forming displays existdisplay that would, upon receiving input from a computer, display the shape of a character or ideogram from an alphabet thus allowing a blind person toto quickly understand the shape of such a character or ideogram? (thinkThink about the 8,000 or so Chinese ideograms whose shape one could want to quickly learn).)
