Two computers, one for the Braille and one for other things like drawing tactile pictures, three screens, a printer and a scanner is the technology I need for my work. Still more is needed before the braille books are ready to be posted to the students.
Of course most blind students rather use electronic books and talking books. But first they must learn to read and write and for that they need Braille books on paper. Talking books don't teach you to read and write.
