T. V. RAMAN 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.
