A system allowing the real-time remote transmission of hand-drawn sketches drawn with conventional means (i.e., a pen or pencil and a piece of paper) is disclosed. The system tracks updates drawn on the paper and transmits them to remote sites. Updates may also be made at remote sites and viewed locally. Also provided are means for archiving and re-playing sequences of updates to a document. Significantly, the system has the ability to track any movements of the paper and to dynamically adjust the system to properly display the image correctly positioned on the paper at the remote sites. |
