iPad stylus: how does it work?

What physical phenomenon does it use? In your finger, it is heat.

About me: I have prehensile eyebrows.
I speak 9 languages fluently, one of which other people can also speak.
When backed into a corner, I fit perfectly - having a right-angled arse.

I am not completely sure, but I imagine that, since the tip is rubber, it compresses when it presses against the screen and so heats up enough to trigger the touchscreen. :tea:

Actually, it is not heat that is registered but changes in capacitance. For this reason, you can't operate an iPad with insulating gloves. Styluses for such kit are designed to have a similar difference in dielectric to human fingers.
