http://store.steampowered.com/livingroom/SteamController/It was slightly dished with -ridges- to provide feedback to how far out of center your thumbs were. The catch was that the ridges pull ever so slightly at the thumb causing it to raise over the ridge and then accelerate after crossing the drag point.By the way, the people suggesting an steam controller like touchpad, didn't get the point at all. What that controller had wasn't touchpads in the usual way, they had some kind of feedback (a subtle vibration) that allowed the user to feel how far the thumb was from the centre. Although I want to try such a solution I don't think it fits a device like the Pyra.
Their concept was good - their production was bad.
My idea is a similar concept, but instead of ridges, use a broad parabolic cup so it's noticeable as your thumb climbs the sides. Mapped to acceleration signals it would give very fine control in the bottom of the cup and then increase exponentially toward the upper lip.
I'd also thought about inverting it into two small hills for the thumb to run up and over and around - but that would look a bit too much like an anatomy experiment gone wrong.
