I'm having some trouble finding a place to put this question, since I don't have any insight in coding. Please let me know if the thread is misplaced, and I'll move it.
Question:
I have an idea of an app for iPhone/any smart phone and before I move on with the idea I need to know if the following is even doable.
You'll have to take a picture of text (on paper) with the phone's camera and the app will have to interpret the text and "know" what letters/words are used. It that far off, or is it possible to do with the current technology?
Do you know of any examples where it's been used before?
