Yes, resolution/steps for the mouse is important here. Someone in the IRC channel threw out that I may want to look into bipolar interpolation so accomplish this, but I don't know if he was serious or just be a smart a$$.
As far as using your finger for a stylus it works quit well with the implementation that I have, however, I am limited to the motion possible on the computer screen due to the tablet resolution being smaller.
I have also tried:
xMove = (computerScreenWidth / tabletScreenWidth) * incomingTabletXCoord;
but I don't get the smoothness desired, and it tends to "step" around.
Any other suggestions?
