Leap motion + kangaroo

Hi all, I'm trying to move some objects in Rhino through the Leap Motion device. I connected the points identified by the fingers of my hand at the corner of a cube using the Magnet Snap command but the Solver Kangaroo seems to read only the starting points of my hand and they don't move with the passing of the time; so the cube doesn't follow my hand. It seems that there ins't a refresh of the points gived by my hand that Kangaroo or Magnet Snap introduces.
Can someone help me to solve the problem?
Have you some suggestion or other ideas to move objects with Leap Motion device?
Thanks a lot
