hi guy's

I wrote a program based on tuiodemo. on the side of the fiducial, I have a volume. volume function works with tcur.getY (); tcur.getY () works with the height of the window of the program.
(0 at the top and 1 at the bottom of screen)
if I put the finger on top of the screen, the circle go to the top of the arc, if I put my finger on down of the screen, the circle go to the bottom of the arc.
tcur.getY (); must work with the height of the arc next to the fiducial
So if I put the finger on the top of the arc, the circle must go to the top of the arc
and if I should put the finger on the bottom of the arc, the circle must go to the bottom of the arc

look the problem with TUIO simulator

Thx

this is the code;
