How does a laptop's touchpad work?

I had been using my laptop for the past four years and its good to have a touchpad other than a mouse as it offers more ease on working and moving files all over the desktop but my question is how does a touch pad works and it remains a mystery to me because as far as I know there are two methods tp give input such as capacitive and a resistive method as we use in mobile phones.Both of them has different principle and what amuses is that touchpad workng.It can be accessed through capacitive touch but even I can move the cursor with many objects.So please explain briefly.
Is there any stylus available so that i can use it as input in paint application and sketchbook pro?

    There are many websites which give clear information on how stuff works?

    Please avoid making threads which doesnt add value to the forum. I have seen couple of threads which are started and are answered by others , but you never respond to those threads again.
