FingerReader

Scientists at the Massachusetts Institute of Technology are developing an audio reading device to be worn on the index finger of people whose vision is impaired, giving them affordable and immediate access to printed words.

The so-called FingerReader, a prototype produced by a 3-D printer, fits like a ring on the user’s finger, equipped with a small camera that scans text. A synthesized voice reads words aloud, quickly translating books, restaurant menus and other needed materials for daily living, especially away from home or office.

The opposing view? Here:

The road to hell is paved with good intentions. Do the blind really want an audio reader? Most non-blind or hearing impaired do not understand the culture that lies in these communities, and are treated with a parental nurturing philosophy that borders on being totally insensitive to the needs of these communities. Did any one of these Samaritans ever ask the blind if they even want this. As far as I know most blind would prefer to read from a brail [sic] book, their second choice is an audio reader. When it comes to brail [sic] it is hard to create a page with a large array of dimples that would allow the blind freedom of reading (books, newsprint and leaflets). The visual impaired have a greater tactual sensitivity than all sighted people could never have, not understanding this aspect of their lives means not understanding the community you are trying to aid. 

As far as computers is concerned, they have their own text to audio readers; which just needs to be switched on.
