K-NFB Reader

The K-NFB Reader (an acronym for Kurzweil — National Federation of the Blind Reader) is a handheld electronic reading device for the blind. It was developed in a partnership between Ray Kurzweil and National Federation of the Blind.
The original version of the reader was composed of a digital camera and a PDA, which contained specialised OCR software and speech synthesizers to read the scanned material aloud. It was released at a price of $3,495.
The software was later ported to the Symbian operating system, to be used on Nokia N82 camera phones, with a new price of $1,595.
In 2014, an iOS port was released at a price of $99. An Android version was released shortly after.
