Most touch screens don't even know that. Whatever they do know is massaged by the touch screen driver into the events you receive in the SDK before it even gets out of the touch screen. (There *is* some more data that may be reported, and a future version of the platform will have these fields. But don't count on doing a whole lot with them; most touch screens I have seen have very little data available here.)
