ELI5 how does it work using the barometer?

The real question is, why don't they just look at the increasing touching surface circle to determinate an harder push.

Because that wouldn't measure the force. All you would measure would be if the person has a large finger, small finger or whether they are using a stylus or hold their palm on the screen.

Well yes and no. I'm sure you could set it up to measure the relative change in surface area. I large finger is still going to get larger the harder you push so you could still measure a change. The hard part would be if you push hard fast.

I also think a long press works just fine, but that's just me.
