Just thinking out loud, I wonder if this pad could simulate a keyboard, and here's what I mean: a lot of us don't actually look at the keyboard while typing. I'm picturing a scenario where your two index fingers are somehow centered on this pad - just as the letters "f" and "j" have a raised feel so you can blindly find them - and once centered, you type as you normally would, and this pad "knows" what you are typing based on the approximate location of your taps alongside the corrective spelling like on the iPhone. Just a thought.
