drawing with a fist

Hi everyone,

I wrote a program to allow drawing lines with a fist rather than a finger on iPad2.

Recently I tried it on iPad Pro, and found it not working.

touchesCancelled of UITouch were observed right after touchesBegan on iPad pro, where lots of touchesMoved and a touchesEnded at the end were observed on iPad2.

Is there any way to make the iPad pro behave like iPad2?

My guess is that the iPad Pro has more aggressive palm rejection, to improve the experience of using the pen. Or, it may be a consequence of how the multi-touch hardware works.


Is this accessibility-related? I don't see any accessibility settings related to touch for people who can't use individual fingers on the screen, but I may not have looked in the right place.


This might be a good candidate for using a TSI (tech support incident) to get an answer from an Apple engineer directly, since (my guess is) this is a more difficult issue than it seems.
