Most of the time you see people using their voices to talk. Those talking voices can be written down as words on paper. Then we can read those talking voices. We put those papers together and call them books.
But some people can’t hear! What do those people do? They don’t use their voices. They use their hands to talk to each other. But those talking hands can’t be written down on paper yet. How do we make books if we can’t write down talking hands?
Those people use computers to make movies of talking hands. Those movies can be shared with many other people, like books are shared with many other people. But movies are not books.
Now computers can make books too. We don’t need paper anymore. So we can put both words and movies in the computer. People can then decide to read words of talking voices, or watch movies of talking hands.
If there is a good story in the computer, kids can pick to read the story or watch the story!” —Adam Stone. An explanation of ASL/English bilingual ebooks (more info at www.foundinblank.com)
