Some mobile phone manufacturers are now trying to create phones for blind people. On the picture you can see such a handset, designed by Peter Lau. It lacks a screen and comes with angled keys to ease the usage. Because the blind can not read and type, some kind of text-to-speech software should be loaded on this phone to read the incoming messages and those being typed.
Such devices could positively change the lives of millions and help the blind to get more familiar with the modern technology.
