Leap Motion : collision between hand and fixed objects

Hello,

I just bought the Leap Motion with the aim to use it in Unity with the Oculus DK2. To use it I downloaded the .unitypackage on the developpers zone of leap motion.
It works very fine. I manage to move objects with my hands.
Now I want to have fixed objects which will block my virtual hand. I tried several solutions :
-just use a collider ; the hand pass through the object
-add a rigidbody and full freeze it ; the hand pass through the object
-add a fixed join ; the object move when I touch it and come to it initial position
Does anyone have an idea how get this result?

Thanks

 

We would generally recommend against overriding user-driven hand motion, for some of the same reasons that you should never override user-driven head motion -- it's really disconcerting and breaks presence.
