A system is described for creating paper documents that show images of presentation slides and bar codes that point to a multimedia recording of a presentation that has not yet occurred. An image-matching algorithm applied after a presentation determines when each slide was displayed. These time-stamps map the bar codes onto commands that control a multimedia player. We describe the system infrastructure that allows us to prepare such prescient documents and the document image-matching algorithm that enables the mapping of bar codes onto the times when slides were displayed. This provides a multimedia annotation tool that requires no electronic device at capture time.
