ABSTRACT:
This disclosure provides a data recording system and, in particular, an electronic digitizing clipboard and a remote computer. A stylus of the clipboard is used to write on pages, with a digitizer underneath the pages generating an electronic record of entered marks for storage and later recreation of the pages. The electronic record represents both stylus spatial coordinates, normally sampled every ten milliseconds, certain user commands such as page identification, inserted at significant locations within the aggregate data stream, or other data, for example, audio data from a built-in microphone. Data in the stream is associated with prior page identification commands, such that subsequent data may be cut or sorted based upon timing of that data relative to the page identification commands. In this manner, data may be distinguished and moved by a "splicing" mechanism, notwithstanding any spatial overlap with previous stylus data.
