    I've never tried BigScreen, but Canvases are just 3D objects like everything else in Unity. Move it by changing its transform.position.

    Thx @JoeStrout for your reply!
    I use the UIHelper prefab in the oculus intergration package to have a laser pointer. With this i can interact with buttons and sliders. But how can i move and rotate / drag by clicking the trigger and put the canvas to a new location with the laserpointer tip until trigger is realeased? i have no idea how to achieve this in code, hope you can help me this.

    Ah, you just have to detect when the trigger button is down (probably using the Input class, though you could also use an EventTrigger on whatever part of the canvas you want to be grabbable), and then while that is true, move the Canvas in the same way as the pointer.

    There are lots of ways to do that — easiest might be to actually use Transform.SetParent to put the Canvas transform under the controller object (i.e. the thing that represents the actual thing in your hand) while the button is down. Then set its parent back to nil when the trigger is released.
