Is it possible to attach a rigidbody and box collider component to the main camera in Unity and have it trigger interactive objects in an AR scene using the STYLY Interaction SDK?
As far as I know, this is not possible. That said, you can use the STYLY Interaction SDK to add the STYLY_Attr_Draggable component to a game object in combination with the STYLY_Attr_Collision component to create an interaction between two game objects. You can also use Unity's Event Trigger component as well to make a simple, clickable game object.
It is not recommended to add or modify Components to the camera's GameObject.
What kind of scene of movement do you want to create? I may be able to find out other options.
