While this seems neat for helping with autocorrection, I'm really skeptical any user would ever use it on purpose. I type a lot and I doubt I'd be able or would even try to do it blindly above the keyboard. If I saw I had missed one key I'd probably reflexively hit backspace, and even if I didn't I'd try to type the rest of the word properly, rather than all shifted the same way, which would make this not at all better than the autocorrect that currently comes with modern smartphones.
