US Patent 7721209 Object-aware transitions

Techniques for accomplishing slide transitions in a presentation are disclosed. In accordance with these techniques, objects within the slides are identified, automatically or by a user, and each object is individually manipulable during slide transitions. The individual manipulation applied to each object during a transition may also be automatically determined or specified by a user. In certain embodiments, the persistence of an object between slides may be taken into account in the manipulation of the object during slide transition.
