A Touch Sreen act like a mouse. The touch screen driver translates all
the ts stuff to mouse commands (like WM_LBUTTONDOWN, etc).

The ts (touch screen) comes with a driver that translates the ts stuff
to the mouse stuff. You've to forgot that you are programming with a ts.
When the user put his finger on a place in the screen, you'll receive a
WM_LBUTTONDOWN message (or a MouseDowun event handler in C# under .NET,
and the equivalent event in MFC programming, or Visual Basic or
C++Builder or Delphi).

The ts comes with a Calibrate program that allows to calibrate the ts,
because the most of ts are capacitive and needs to be calibrate frecuently.

In other hands, some ts (like ultrasound ones form elo) can get the
amount of pressure, and comes with API extensions in order to get them
to work. See at http://www.elotouch.com/support/dnld.asp (see
Programmers Technical Reference near fo the end of the page) to get the
programming and installing interface for the elo ts.
