<P>PROBLEM TO BE SOLVED: To attain a device which can electronically record all data written on a whiteboard and all data erased from the board, and accurately display how information has been generated and changed on the whiteboard in real time or later on a computer screen by a relatively simple and inexpensive method. <P>SOLUTION: A system for displaying information includes a writing board provided with an optically readable position-coding pattern; a first device adapted to create, on the basis of the optically readable position-coding pattern, an electronic representation of information which is being written on the writing board; and a second device adapted to create, on the basis of the optically readable position-coding pattern, an electronic representation of information which is being erased from the writing board with an eraser. <P>COPYRIGHT: (C)2011,JPO&INPIT |
