The New York Times:
MOUNTAIN VIEW, Calif. -- T. V. RAMAN (pictured) was a bookish child who developed a love of math and puzzles at an early age.
That passion didn’t change after glaucoma took his eyesight at the age of 14. What changed is the role that technology — and his own innovations — played in helping him pursue his interests. A native of India, Mr. Raman went from relying on volunteers to read him textbooks at a top technical university there to leading a largely autonomous life in Silicon Valley, where he is a highly respected computer scientist and an engineer at Google.
Along the way, Mr. Raman built a series of tools to help him take advantage of objects or technologies that were not designed with blind users in mind. They ranged from a Rubik’s Cube covered in Braille to a software program that can take complex mathematical formulas and read them aloud, which became the subject of his Ph.D. dissertation at Cornell. He also built a version of Google’s search service tailored for blind users.
Mr. Raman, 43, is now working to modify the latest technological gadget that he says could make life easier for blind people: a touch-screen phone.
“What Raman does is amazing,” said Paul Schroeder, vice president for programs and policy at the American Foundation for the Blind, which conducts research on technology that can help visually impaired people. “He is a leading thinker on accessibility issues, and his capacity to design and alter technology to meet his needs is unique.”
Some of Mr. Raman’s innovations may help make electronic gadgets and Web services more user-friendly for everyone. Instead of asking how something should work if a person cannot see, he says he prefers to ask, “How should something work when the user is not looking at the screen?”
Such systems could prove useful for drivers or anyone else who could benefit from eyes-free access to a phone. They could also appeal to aging baby boomers with fading vision who want to keep using technology they’ve come to depend on.
Mr. Raman’s approach reflects a recognition that many innovations designed primarily for people with disabilities have benefited the broader public, said Larry Goldberg, who oversees the National Center for Accessible Media at WGBH, the public broadcasting station in Boston. They include curb cuts for wheelchairs, captions for television broadcasts and optical character-recognition technology, which was fine-tuned to create software that could read printed books aloud and is now used in many computer applications, he said.
With no buttons to guide the fingers on its glassy surface, the touch-screen cellphone may seem a particularly daunting challenge. But Mr. Raman said that with the right tweaks, touch-screen phones — many of which already come equipped with GPS technology and a compass — could help blind people navigate the world.
“How much of a leap of faith does it take for you to realize that your phone could say, ‘Walk straight and within 200 feet you’ll get to the intersection of X and Y,’ ” Mr. Raman said. “This is entirely doable.”
Advocates for the blind have long complained that technology companies have done a generally poor job of making their products accessible. The Web, while opening many opportunities for blind people, is still riddled with obstacles. And sophisticated screen-reader software, which turns documents and Web pages into synthesized speech, can cost more than $1,000. Even with a screen reader, many sites are hard to navigate.
