A method and system for coordinating placement of an augmented reality/virtual world object(s) into a scene relative to position and orientation. The object(s) can be connected to an anchor point having an absolute location relative to the marker via a connector (e.g., spring-like connector) in such a way that the behavior of the object responds to a physical force and a collision which exists in the augmented reality scene.
