abstract = {A video tutorial effectively conveys complex motions, but  may be hard to follow precisely because of its restriction to  a predetermined viewpoint. Augmented reality (AR) tutori-  als have been demonstrated to be more effective. We bring  the advantages of both together by interactively retargeting  conventional, two-dimensional videos into three-dimensional  AR tutorials. Unlike previous work, we do not simply overlay  video, but synthesize 3D-registered motion from the video.  Since the information in the resulting AR tutorial is registered  to 3D objects, the user can freely change the viewpoint with-  out degrading the experience. This approach applies to many  styles of video tutorials. In this work, we concentrate on a  class of tutorials which alter the surface of an object.},
