The documents become more legible by doing the anno tation. There are some systems that support annotating or reading digital document, but they cannot be applied to physically printed-paper documents. Moreover we are not allowed to write notes in vintage books or books of a library. This paper proposes the system of “Digital Book rest”, which adds the electronic property to the physically printed-papers. The components of the proposed system are a digital camera, a video projector and a pen-shape de vice with LED. The system estimates positions of paper documents and annotated points in the captured image, and overlays annotations onto the real paper document using a video projector. The prototype system was implemented, and experiments are performed to confirm the availability.
