Nokia phone cameras will translate words

In the photo, I think, and so everything is clear. Nokia is engaged in the creation of OCR for cameras in their phones. It is clear that the technology will be relevant in cameras with a large number of pixels - about 8-12 megapixels. I think that the technology will be in demand, for example, by tourists.
Tell me, are you surprised by the new technology or has it been discussed somewhere before?
