[Help Wanted] How can I design an object that moves simultaneously to the HoloLens?

Hi,

I created an app that renders images in a sprite object.
But I need the sprite object to move simultaneously to the movement of the HoloLens.
So if turn my head to the left, the sprite should also move to the left. It should always stay in my
field of view.

Is it a matter of settings ?

Thx

I would probably just put the sprite on a UI canvas as an Image component.
