Conference system for enabling concurrent displaying of data from conference presenter and conference participants

摘要

A conference system includes a terminal that displays a document presented by a presenter in a conference and that is capable of receiving writing inputs from a participant for enabling exchange of opinions, and a document storage unit that stores the document used in the conference and the written information. The document storage unit stores image data of respective pages of the document, shared overwrite data for each page including shared written information written by the presenter or participants, and personal overwrite data for each participant provided for each page and including personal memo information written by the participant. The terminal includes a read unit that selectively reads out from the document storage unit, concerning each page, the image data of the presented document, the shared overwrite data, and a participant's personal overwrite data, and a display controller that overlaps the read-out data and displays the overlapped data on a display.
