I need control the sensitivity of the bone animation in kinect v2's avatar control.

I used avatar control and avatar scaler in kinect v2 to make the avatar move along the user when the user is recognized in Kinect.

but, when the user is standing still, the avatar can't stay still and it keeps shaking.

Somehow the other part stopped the tremor, but the tremor of the neck can not be stopped.

I removed the throat from the bone animation, which I know is not the right way.

I need control the sensitivity of the bone animation.

cheer with help.
