UI long term development perspective: physics engine

[Florent THIERY]

Would it be possible to get video captures or raw measurements of the
touchscreen's reported coordinates?

For instance, i'm pretty curious to know what exactly the touchscreen
sees when  you touch the screen with 2 fingers at the same time, when
you move them, when you move only one of the 2, etc....

I'm also interested in knowing how precise the touchscreen is (ex:
refresh rate, possible pressure indication, ...).
