Touch-Hear tactile dictionary
Scientists at the National University of Singapore created the Touch-Hear text recognition dictionary. It consists of 2 parts: a small sensor attached to your finger pads and a speaker attached to your ear. As soon as you touch a word printed in a book with the scanner, you’ll hear its meaning. At the same time, the device doesn’t bother other people at all: only you can hear it.
