	The composition of real and virtual entities has a major contribution to the usability and acceptance of an Augmented Reality (AR) Scene. The composition method highly depends on the accessibility of information in order to allow the user to intuitively perceive relative and absolute distances of objects within the AR scene. This paper proposes a novel, flexible and practical approach of creating a context preserving view onto the operation site. It exclusively employs information from video data of video see-through AR systems to compute context information.
