I can't accept this.Doesn't work.
A touch surface needs to be bigger than your fingers to recognize movement.
Your fingers cover the whole crown.
If they move, the electrical field doesn't change in a meaningful way.
What about fingerprint sensors, some now on android even recognise different swipe directions across the small pad.
If it can detect your fingerprint, it can detect a movement.
Even a normal phone screen tech, can tell what direction your finger moves.
You build either tech into a small area and t can watch (pun intended) for direction of movement across it's surface.
