Any 'swipe' navigation scripts? Any tips?

So I dropped in the dual-joystick prefab for my FPS mobile app. When I watch people try to use it, however, they ALL begin swiping to try to look/move. Joysticks are out.

I need a 'swipe navigation' paradigm. Anyone know of any scripts or prefabs or whatever that implements such?

In any case, any tips? Like swipe left/right to turn? to look? to strafe? Swipe up/down to move forward/back or look up/down? Any thoughts on multi-touch for nav?

Thanks

I have put a simple version of the control mechanism that is similar to the one used in Epic Citadel (tap or joystick to move, drag to look) on the Unify wiki:
