Morrison Heady, who founded the American Printing House, was blind from youth. He invented all sorts of devices for the blind. That's his talking glove that he invented for himself once he was deaf and blind. What you do is, there are letters on the palm of the glove. If you wanted to talk to him, you'd come up and touch the letters.
Visitors can try their hand at producing braille using a special typewriter.
The company's museum displays styluses and slates developed to help the blind write on paper. Roberta Williams says learning to correctly draw the letters is not the problem. What's hard is knowing where you are on the page. So writing guides, like a grid of wires, with spaces between the wires, allow you to keep your orientation on the page so you know that you're going in a straight line. The American Printing House for the Blind does produce some large-print books for those with limited sight.
