Smartphones' accelerometer can track strokes on nearby keyboards

Ignoring the security implications, this could be a great way to use an old spare keyboard for text entry on your phone. And with some training, it would probably be far more than 80% accurate.

That would be pretty interesting since you don't even need to hit the right key - just the left side of the keyboard or the right.

I wonder I could learn to type by just tilting the phone left right in the correct pattern.

Not to rain on your parade here, but eighty percent accuracy would require every sixth keypress to be backspace. Likely promoting it to the most pressed key.

Obviously, auto-correct mitigates this somewhat but for the amount of frustration and lost time, I'm betting it's probably worthwhile just purchasing a new keyboard.

But what if the keyboard – unpowered and wireless – were designed for this purpose, emitting unique sounds per key, perhaps even outside normal human hearing range?
