By such processing, the display device 3 projects the image of the RGB signal from the presentation BOX 1 on the screen SC. During this projection, an effective presentation becomes possible through the exchange of data between the presentation box 1 and the tablet 2.

First, the presentation box 1 sends to the tablet 2 the data of the detailed explanation text necessary for the current presentation screen. This is effective when the presentation screen creator and the presentation user are different. In other words, if the screen data of the presentation is not well understood, this content can be easily known.

When the user makes corrections or additions by handwriting while explaining the presentation screen, the image written on the tablet unit 201 and the LCD 202 of the tablet 2 is sent to the presentation BOX 1 and this data is stored in the display memory. At 103, the overlapping process is performed. Also,
Erasing the data that has been superimposed on the display memory 103,
The change is also performed through an input operation of the input pen 200 on the tablet unit 201 of the tablet 2. In addition, a process of finally storing the superimposed data in the HDD 107 is also performed.

Further, the data read from the FDD unit 206 built in the tablet 2 is also superposed in the same manner as described above, and is also reduced and taken in as a part of the data. In this way, the user using OHP
The explanation can be made in the same way as when explaining the projection screen.

In this embodiment, one tablet 2 has been described, but when using a plurality of tablets, the tablet I / I of the presentation BOX 1 is used.
A plurality of tablets are connected to the F circuit 109. Then, an identification code is given to each of the plurality of tablets, and the identification code is assigned to the C of the presentation box 1.
The PU 105 identifies and sends out the data, and the tablet 105 interrupts the CPU 105 of the presentation BOX 1 with the data to which the identification code is added to exchange the data. In addition to this interrupt processing, you can also use polling processing, time division processing, etc.
The data may be exchanged.
