[Blindmath] Tactile Displays?

[Lori]

Hi, I wonder if it is indeed the Optacon which BTW is still used widely by a 
number of people. I'll try anpost some recent info about the Optacon. But 
the article does say to review pictures not text, but I wonder if that is a 
misunderstanding of the written article, or maybe it is another device.
