PROBLEM TO BE SOLVED: To provide a device which remote operates the presentation by sending the presentation information to be shown on a display device of a terminal of the opposite party via a transmission line and then sending a command to the opposite party terminal via the transmission line to designate the display mode of the presentation information to the display device of the opposite party terminal. SOLUTION: A control part 100 controls the display states of images and data, and an input part 101 inputs the commands for a presenter, i.e., a sender of information to designate the presentation materials and also to progress the presentation. A data storage part 102 preserves the presentation materials, and an output part 103 reproduces the images and voices and also displays the presentation materials. A camera part 105 photographs the presenter himself/ herself at a presenter terminal and also photographs the audiences, a lecture hall, etc., at an audience terminal respectively. A transmission line I/F part 107 connects a physical transmission line to a system, and an enlargement display part 108 enlarges the display contents of the part 103 so as to enable the audiences to see better these contents. |
