K-NFB, a portable device that scans any available text and reads it back to visually impaired people, will be on sale in the UK by July of 2006. The device was developed by Ray Kurzweil.
The K-NFB will cost approximately ?2,625 (that's about US$4,800), which makes it a bit pricey. However, the device is far less costly than one of Kurzweil's earlier efforts, a similar device created in 1981. The "Reading Machine" was the size of a washing machine and cost more than $50,000.
This is yet another area in which science fiction writers were first to describe a demand—and a solution. In his 1934 story The Lost Language, writer David H. Keller describes a device that is actually able to make speech from printed text—the sound-transposing machine:
In a month's time, tired people will be placing pages of a book in their machine and hear it read to them..."
Then an entire page of the lad's typing was run through the sound-transposing machine, purposely slowed so that the sounds could be differentiated.
