I have noticed that some CAPTCHA pages, like Cloudflare’s, simply ask you to check a box to proceed. There is no clicking on traffic lights or entering characters. How does clicking on a check box tell them I am not a robot?

Then why do we still need to click it, instead of just loading the page at once?
Because it measures how your mouse moves to the checkbox. If there was nothing to move to, you wouldn’t move your mouse.
I get the checkbox even on mobile sometimes, I imagine as long as you’re not perfectly hitting the center pixel it knows you’re human.
But that would be easy to program a bit for
Yeah, that sounds reasonable. Touch input is reported similar to mouse input, so it would translate to a touch screen pretty well.
