You guys are completely missing it...

A touchpad is normally a relative movement method. I.E. Press anywhere and drag in a direction and the mouse moves from its current position in that direction a certain distance. This is exactly how a normal mouse works, except with reversed traction .

What ISG is looking for is using the touchpad as if it were a tablet (unless I am mistaken) so that when you press in the top left corner, it moves the mouse instantly to the top left corner of the screen. This way, depression on the pad is comparable to touching a brush to the canvas and drawing, letting up stops. With the normal functionality, the depression and drag is for moving, and the click for painting. It makes it one less step of interaction and more intuitive.

As far as I know, it's possible, but I'm not sure exactly how. You probably need to create a DLL (or use Lite-C) to access windows API calls to interact at a lower level with the device and determine if there is any depression, and if so, where that depression is located on the pad.
