touch event handlers in the mobile space and some of the extra data that goes with them

I caught dinner with Jagruthi Mamidi and Azadeth Razaghian yesterday. Jagruthi spoke of a project she had worked on in the android development space in which she calculated the movement of a shape based upon a "touch event." She mentioned that the event carried with it a variable for the amount of force the user gave in touching the touch screen and another variable for the direction the finger was drug across the touch screen.
