T.V. Raman is working on touch-screen phones

On a recent "The New York Times" article there's a story about T.V. Raman, a well-known Google engineer, and his recent works.
He's currently busy exploring ways to allow blind people to use touch-screen phones.

We might have noticed that touch-screen interfaces are quickly spreading, from mobile phones to desktop PC. Although sighted users love this kind of UI, we cannot ignore that they constitue yet another barrier for visually impaired and motor impaired users.

Thus, IMHO, it is a great news that someone is actually walking his way to reduce the digital divide.

What's your opinion about that?
