Thank you for your answer Alex!
Some update on this:
There doesn't seem to be anyplace to modify the stabilized position of the LeapPalmData since it is not used anywhere. But using this could solve my problem. I cannot find the place where leapmotion controls the position of the hands anywhere.
Is there anyway to control the position of the visible hand(s)?
Do I need to make a custom skeleton that follows the hand but 0.5x the speed or something and hide the leap motion hand?
Any suggestions would be welcome!
