As an artificial intelligence graduate student at the University of Washington, Jeffrey P. Bigham wanted to build systems to help people accomplish their goals, but he did not want to necessarily design new machine learning algorithms. He started working in the lab of computer science and engineering professor Richard Ladner, whose research focuses on accessibility technology for people with disabilities, especially for deaf, hard-of-hearing, deaf-blind, and blind people. One day Bigham watched a blind graduate student struggle to book an airline ticket via the Web. "That was powerful," recalls Bigham. "I saw this guy, who I really respected because of his intelligence and ability to get things done, having such difficulty. I feel that's something we shouldn't allow to happen and something we should be able to fix."
