1948年，在出生后数月，罗恩·麦卡勒姆失明了。在这场令人陶醉的，感人的演讲中，他展示了他如何可以阅读--并庆祝了巧妙工具的发展和高度适应的电脑科技如何让这一切成为可能。通过它们的帮助，和慷慨的志愿者们，他成为了一名律师，一名学者，最重要的是，一名贪婪的阅读者。欢迎领略失明者的阅读革命。（录制于TEDxSydney。）

科技如何让我阅读

Technology has transformed access to reading for millions of blind people, turning dreams once thought impossible into reality. From braille and tape recorders to computers and screen readers, each leap in innovation has been powered by both passionate inventors and dedicated volunteers. In the 1980s, a computer with just 84 kilobytes of memory was a breakthrough, and now screen-reading software fits on a smartphone. Despite these advances, legal and digital barriers still keep many books and websites out of reach for those without sight.
