For the Blind, Technology Does What a Guide Dog Can’t

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.
