3D GameObject set to ARCamera

Hi,
I set GameObject as child to ARCamera, but result don't satisfied me. I wanted this GameObject to stay always in the same position on the screen. Is there any method to do this or expleination why it isn't working?

 

This is not really a Vuforia / AR question, is it?
If you aim to get a GameObject to stay in a fixed position on your screen... well just use a regular Unity Camera.

Vuforia Augmented Reality is about placing objects in the real / physical space. So you sort of stick a GameObject to a part of the physical space. It would be an unnecessarily complex approach to use AR technology to keep a GameObject in the same spot in screen space.

Here's an attempt to help you;

1. place the GameObject in your scene
2. aim a Camera at it.

Done.
