Ron Mc Callum: How technology allowed me to read

Months after he was born, in 1948, Ron McCallum became blind. In this charming, moving talk, he shows how he is able to read and celebrates the progression of clever tools and adaptive computer technologies that make it possible. With their help, and that of generous volunteers, he s become a lawyer, an academic, and, most of all, a voracious reader. Welcome to the blind reading revolution.
