The material information window 320 is displayed with reference to the material object table 410 (step 730). If the input is not a display operation of the material information window, other necessary processing according to the input is performed (step 760).

If the input is not to the material object in step 620, it is determined whether the data is a material reception report received from another site via the communication control unit 340 (step 690). If it is a material reception report, the material object table 410 is updated (step 700), the display of the conference window is changed, and a new material object corresponding to the received material is displayed in the form of a physical object 280 ( Step 7
10). If it is determined in step 690 that the input is not the material reception report, then the communication control unit 340 is sent from another site.
It is determined whether or not it is the participation / leaving report received via (step 740). If it is a participation / leaving report,
Perform participant object processing (step 750). If the input is not the participation / leaving report, it is determined whether the material information reception report is received (step 770). If the material information has been received, then the material information processing is performed (step 780), and if the material information has not been received, other processing according to the input content is performed (step 790).

FIG. 10 shows an operation of selecting a material object in the partner area 270 with a mouse to display a material information window 320 attached to the material object. The material information window 320 displays a material name 322, a creator 324 of the material, a holder 326 of the material, and other information 328.

FIG. 11 shows the user interface section 350.
The flow of participant object processing in is shown. The participant object process 750 is a process for changing the display of the participant object 230 of the conference window 200 when a new participant or a leaving person occurs.

First, when an input is received, it is determined whether or not it is a participation report (step 752). If it is a participation report, an empty area of the partner area 270 on the conference window 200 is allocated to the new participant (step 754). The participant object 230 is newly displayed in the partner area 270 (step 756), one record of the area information table 400 is generated, and the content is updated (step 758). In the determination at step 752,
If the input is not a participation report, it is next determined whether or not it is a leaving report (step 760). If the input is a leaving report, the corresponding participant object 230 is deleted from the conference window 200 (step 762), and the partner area 270 reserved for the participant is released (step 7).
64). The record of the participant is released from the area information table 400 and the content is updated (step 76).
6). If it is determined in step 760 that the input is not the leaving report, error processing is performed (step 768).

FIG. 12 shows the user interface section 350.
7 shows a processing flow of material information processing 780 in FIG. When only the material information is received, not the substance AP, the area information table 400 is referred to (step 782). The received material information has a header attached to the data because it is transmitted through the communication control unit 340. From this header,
The participant who issued the material information is determined and compared with the area information table 400 to determine the area identifier 4 of the participant.
Get 02. From this, the partner area 270 of the material holding participant is determined (step 784). A dummy object of the material is newly displayed on the partner area 270 (step 786). For this material, a new material object table 410 is created,
The contents are updated (step 788).

FIG. 13 shows the user interface section 350.

As shown in FIG. 14, the movement of the material object 280 is performed from the personal area 210, that is, the movement source is the personal area, and the movement destination is the OHP object 300 and the common area 26.
0, the partner area 270, etc. can be considered.

In FIG. 14, the material object corresponding to the material object can be distributed to other participants by moving the material object in the personal area 210 with the mouse 180-B. In the figure, by continuously moving the opponent area with the mouse, all other participants corresponding to the opponent area can collectively see the material AP.
Shows how to distribute. As a result, even when the material AP is distributed, the operation of designating the address, name, etc. of the other participant is unnecessary, and it is possible by a direct operation of moving the material object.

In FIG. 13, when a movement operation of the material object is performed from the personal area 210 on the conference window 200, the movement destination of the material object 280 is determined (step 672). The following processing is performed according to this destination. It is determined whether the movement destination of the material object 280 is an OHP object (step 674), and when the movement destination is the OHP object 300, the OHP processing 790 is performed. If the destination is not the OHP object, it is determined whether the destination is the shared area 260 (step 676). If it is the shared area 260, the display of the material object 280 is changed in the conference window (step 678), and the contents of the area information table 400 and the material object table 410 are updated (step 682). Then, the material information of the material is passed to the communication control unit 340 in order to inform the other participants that the material object 280 is newly provided in the shared place (step 68).
2). If it is determined in step 676 that the movement destination of the material object 280 is not the common area, it is next determined whether or not the movement destination is the partner area 270 (step 6
84). If the destination is the partner area 270, the area information table 400 is referred to (step 68).
6) It is checked whether or not there is a participant corresponding to the partner area 270 which is the destination (step 688). If there is a participant corresponding to the partner area 270, a material transmission request is issued to the material transmitting / receiving unit (step 360). If the movement destination of the material object 280 is not also the partner area, other processing according to the movement destination is performed (step 692).

FIG. 15 shows a change in the conference window of the participants of the distributed site as a result of the communication processing 360 of the material AP. The material object corresponding to the distributed material AP is displayed on the shared area 260 as a physical object 280.

An operation for issuing a request to be executed to the participant is shown. As a result, even if a material AP that is not under him / her is output, the output of the material AP can be displayed on the workstation screen of the own site by having other participants centrally execute the material AP that only the participant has. Can be displayed on.

First, the type of the material object 280 overlapping the OHP object is checked by referring to the material object table 410 (step 792). Next, it is determined whether or not the material object 280 is a physical object (step 794). If the material object 280 is a physical object, the material AP corresponding to the material object is on the own site, so the material AP is centrally executed ( Step 796). If it is determined in step 794 that the material object 280 is not a substantial object, it is next determined whether or not it is a dummy object (step 7
98). The material object is a dummy object 28
If it is 2, it means that the document object does not exist in the own site. Therefore, the material object table 410
And refers to the material A corresponding to the material object 282.
The holding site of P is determined (step 800), and a request is issued to the holding site together with the AP name to execute the AP centralized processing through the communication control unit (step 80).

FIG. 18 shows the conference window program 33.
6 is a diagram showing a processing flow of a material transmitting / receiving unit 360 in 0.

Upon receiving the input, the material transmitting / receiving unit 360 determines whether the input is a material transmission request issued by the user's input operation from the user interface unit 350 (step 810). If it is a material transmission request, first, the material name to be transmitted is transmitted to the corresponding participant with an appropriate communication header (step 8).
12) Then, the file of the material AP is transmitted (81
4). If it is determined in step 810 that the received input is not a material transmission request, it is determined whether it is a material reception report from another site (step 816). If it is a material reception report, first, the material name to be received is received (step 818), and then the file of the material AP is received (step 820). Then, the reception of the material is reported to the user interface unit together with information such as the material name (step 822). If it is not the material reception report in step 816, other processing is performed according to the content of the received input (step 824).
