Touch finger size detection

Question

I was wondering if there is a way to find out the size of the face finger when they touch the Android device. I want to know this, so I can change the sensitivity of certain objects in my game.

Answer 1

A solution for devices that do not offer the touch.getSize () function, you can have a graph with a high resolution of 2d points on the initial screen. To the touch, find the affected ones and there you can have a fairly accurate area as far as the thumb.
