An illustrative demonstration apparatus for use in storing information in a memory is disclosed. The apparatus comprises a reusable panel for temporary display of user-drawn marks, a digitizer for generating digital information corresponding to the user-drawn marks, and an indexer for associating the digital information with a header. The header is based at least in part on a selected portion of the user-drawn marks selected by the user. The apparatus may also feature a redisplay capability permitting redisplay of the user-drawn marks on the reusable panel based on the digital information. <??>One embodiment of the present invention is a whiteboard with a panel for use with dry-erase markers and a scanner that is adapted to the system and method of the present invention with the addition of a touchscreen display and plotter for reproducing notes on the whiteboard panel. Notes having one or more key regions circled may be scanned and circled region extraction technology utilized to extract a header for indexing the notes that may be recognized text within and/or images of the circled regions, with the circles optionally removed. Headers are displayed on the touchscreen for browsing, and associated notes of a selected header are concurrently displayed. Notes may be printed, plotted, or otherwise further utilized at the user's option and as further supported. <??>Additional embodiments include implementation with communication and other illustrative demonstration apparatuses having active displays and the ability to accept user drawn marks as input. <IMAGE>
