A question of how to connect VIVE wands with Unity VR samples

I am very new for VR development and studying Unity VR Samples.
I have HTC VIVE and see VR samples with open VR setting.
In the open VR setting, the pink pointer (as attached) doesn't work for VIVE wands. I think It's not a raycast problem.

What I want is when I click the pink pointer on my computer, then it works and I can change the next scene.

I want to use VIVE wands(controller) in Unity VR samples. Is there anybody know how to connect? I couldn't find the right answers for me.

Thank you in advance.
