The hand blackboard 313 has an input control section 314 and a display control section 3.
It consists of 15.

Next, the information editing method in this embodiment will be explained using FIG. 1(a) and FIG. 1(b).

FIG. 1(a) shows the editing procedure performed by the user.

When editing handwritten information, in step 101, it is selected whether or not to edit.

If no editing is to be performed, the process ends.

When editing is to be performed, in step 102, the user instructs the information to be edited from among the handwritten information displayed on the common display board from the blackboard at hand.

Next, in step 103, the user selects an editing method, ie, "move,""copy,""enlarge/reduce," or "delete" from the blackboard at hand.

If the selected editing method is "Move", step 1
In step 05, specify the destination from the blackboard at hand, and proceed to step 111.
Proceed to.

If the selected editing method is "Copy", step 1
In step 07, specify the copy destination from the blackboard at hand, and proceed to step 111.
Proceed to.

If the selected editing method is "enlargement/reduction", in step 109 the user instructs the size from the blackboard, and proceeds to step 111.

If the selected editing method is "delete", the process directly advances to step 111.

In step 111, the handwritten information instructed in step 102 is edited according to the editing method selected in step 103, and the editing is completed.

The processing executed by the main processing device and the sub-processing device in response to the above operating procedure will be explained using FIG. 1(b).

It should be noted that the main processing device processes the common display board, and each sub-processing device processes the local blackboard.

In FIG. 1(b), when the user specifies handwritten information to be edited, the sub-processing device performs step 120.
Then, the handwritten information is set to a selected state. The sub-processor then forwards the selected message 129 to the main processor.

Upon receiving the selection message 129, the main processing device determines in step 121 whether the handwritten information can be selected. The criterion here is determined by whether the handwritten information has been selected from another handwritten blackboard. That is, if a selection has already been made from another hand-held blackboard, in order to avoid editing conflicts due to conflicts, it is determined that the selection is impossible, the impossible message 130 is transferred to the sub-processing device, and the selection is made. prevent it from happening. Note that a specific determination method will be explained in detail later.

In step 122, the sub-processing device that has received the impossible message 130 abandons the selected state of the handwritten information and displays a message on the blackboard at hand to the effect that the user cannot select it.

On the other hand, when the main processing device determines in step 121 that the handwritten information is selectable, that is, when the handwritten information is not selected from other handwritten blackboards, the main processing device sets the handwritten information to a selected state. and enable message 1
31 to the sub-processing device.

The sub-processing device that has received the possible message 131 displays an edit menu in step 123 to prompt the user to make a menu selection. The user can freely perform editing processing by selecting an arbitrary editing method from this menu. The method that the user can select is "Move j" described in FIG. 1(a).

These are "copy,""enlarge/reduce," and "delete," but here we will explain the process when "move" is selected.

Processing when other editing methods are selected can be performed in the same way.

When "Move" is selected in step 124, the sub-processing device further prompts the user to specify the destination, and the user instructs the destination accordingly.

When the destination is specified in step 125, the sub-processing device moves the handwritten information displayed on the blackboard to the specified destination in step 126, and sends an execution message 132 to the main processing device. Transfer.

Upon receiving the execution message 132, the main processing device moves the handwritten information to the designated destination in step 127, similar to the processing performed by the sub-processing device. Finally, in step 128, the 1 selection state is abandoned and the termination message 133 is transferred to the sub-processing device.

Due to the stiffness, the series of editing processes is terminated.

(The following is a margin.) Next, a method of changing the attributes of information in this embodiment will be explained using FIG. 2(a) and FIG. 2(b).

FIG. 2(a) shows the procedure for changing attributes performed by the user.

When changing the attributes of handwritten information, step 201
, select whether or not to change the attributes. If no attribute changes are to be made, the process ends.

If attributes are to be changed, step 202 is performed.

From among the handwritten information displayed on the common display board, specify the information whose attributes you want to change from the blackboard at hand. Next, in step 203, the attributes to be changed.

That is, "line type", "thickness", and "color" are selected from the blackboard.

If the selected attribute is "line type", step 205
Select the desired line type from the blackboard at hand, and proceed to step 210.
Proceed to.

If the selected attribute is "thickness", step 207
Then, select the desired thickness from the blackboard at hand, and proceed to step 210.
Proceed to.

If the selected attribute is "r color", in step 209 a desired color is selected from the blackboard at hand, and the process proceeds to step 210.

In step 210, the handwritten information instructed in step 202 is changed to the attribute selected in step 203, and the attribute change is completed.

The processing executed by the main processing device and the sub-processing device in response to the above operating procedure will be explained using FIG. 1(b).

It should be noted that the main processing device processes the common display board, and each sub-processing device processes one blackboard.

In FIG. 1(b), when the user specifies handwritten information to be subjected to attribute change processing, the sub-processing device performs step 2.
At step 20, the handwritten information is set to a selected state. The sub-processor then forwards the selected message 229 to the main processor.

The main processing device that has received the selection message 229 determines in step 221 whether or not the handwritten information can be selected. The determination criteria here are also the same as described above.

If the main processing device determines in step 221 that the handwritten information is selectable, it transfers the impossible message 230 to the sub-processing device to prevent selection.

In step 222, the sub-processing device that has received the impossible message 230 abandons the selection state of the handwritten information and displays a message on the blackboard at hand informing the user that the handwritten information cannot be selected.

On the other hand, if the main processing device determines in step 221 that the handwritten information is selectable, it sets the handwritten information in a selected state and transfers the possible message 231 to the subprocessing device.

The sub-processing device that has received the possible message 231 displays an attribute change menu in step 223 to prompt the user to select the menu. The user can freely change attributes by selecting any attribute from this menu. The attributes that the user can select are shown in Figure 2 (a).
``line type'', ``thickness'', and r color'' described in 1. Here, the processing when ``line type'' is selected will be explained.

Processing when other attributes are selected can be performed in the same way.

When "line type" is selected in step 224, the sub-processing device further displays a line type selection menu and prompts the user to select the menu. The user can change the line type to a desired one by selecting an arbitrary line type from this menu.

When the line type is selected in step 225, the sub-processing device changes the handwritten information displayed on the hand-held blackboard to the selected line type in step 226, and further sends an execution message 232 to the main processing device. Transfer.

The main processing device that has received the execution message 232 changes the handwritten information to the selected line type in step 227, similar to the processing performed by the sub-processing device. Finally, in step 228, the selection state is abandoned and the termination message 233 is transferred to the sub-processing device.

This completes the series of attribute change processing.

Upon receiving the selection message 129, the main processing device immediately starts the process shown in FIG. 8(a).

In FIG. 8(a), the main processing unit first checks in step 801 whether the corresponding handwritten information has already been selected from another handwritten blackboard. If it has already been selected from another blackboard, in step 804,
An impossible message 130 is sent to the corresponding hand-held blackboard, that is, the sub-processing device that sent the selection message 129.
Output.

On the other hand, if the corresponding handwritten information is not selected from any of the handwritten blackboards, in step 802, the item "Status" in the management table is set to "Selected". and,
In step 803, the possible message 131 is outputted to the relevant blackboard, that is, the sub-processing device to which the selection message 129 was sent.

For example, when the management table is in the state shown in FIG. 9, if the handwritten information from the blackboard B sends the selection message 129 for the handwritten information with the handwritten information identification number 2, this handwritten information has already been selected by the blackboard A. Therefore, the main processing unit outputs an impossible message 130 to the handheld blackboard B. Furthermore, when the first hand blackboard B sends a selection message 129 for the handwritten information with the handwritten information identification number 3,
Since this handwritten information has not been selected from any of the handwritten blackboards, the main processing device outputs the possible message 131 to the handwritten blackboard B.

FIG. 8(b) is a flowchart showing the flow of processing corresponding to the processing in step 128 of FIG. 1(b).

When the series of processes shown in FIG. 1(b) is completed, the main processing device abandons the selected state of the corresponding handwritten information. Specifically, as shown in FIG. 8(b), the main processing device:
In step 805, the item "Status" in the management table is changed to "
Reset to "Unselected".

As a result, the handwritten information can be selected by another blackboard in the future.

Further detailed operation will be explained using FIG. 10.

FIG. 10 shows a main processing device 1010 (i.e., a common display board) and a sub-processing device 1011 (i.e., a handheld blackboard).
FIG. 2 is a sequence diagram showing the exchange of information between the sub-processing device 1012 (ie, the handheld blackboard) and the sub-processing device 1012 (ie, the handheld blackboard).

When attempting to edit handwritten information displayed on the common display board 1010 from the handwritten blackboard 1011, target information is first selected from the handwritten blackboard 1011. That is,
A selection request 1013 is output from the handheld blackboard 1011 to the common display board 1010.

In response to this, the common display board 1010 only when the selected handwritten information is not selected from other handwritten blackboards.
Output permission 1014 on the hand blackboard 1o11.

The blackboard at hand 1011 that received permission 1014 is finished editing 1
Until 018 is output, that is, during the selected information editing period 1021, the handwritten information can be edited freely.

During this selected information editing period 1o21, for example, the 10th
As shown in the figure, when there is a selection request 1016 for the same handwritten information from another handwritten blackboard worker 012, the selected information has already been selected on the handwritten blackboard 1011, so the common display board 1010 displays the handwritten information on the handwritten blackboard 1012. Outputs Rejection 1o17. Therefore, the hand-held blackboard 1012 is the hand-held blackboard 1o.
The handwritten information being edited by 11 cannot be edited.

゛Editing completed 1 from hand blackboard 1o11 to common display board 1010
After outputting 018, if there is a selection request 1o19 from another handheld blackboard 1012 as shown in FIG. Therefore, the common display board 1o10 outputs permission 1020 to the handheld blackboard 1012.

As described above, according to the present embodiment, the handwritten information can be edited by the handwritten information displayed on the common display board by the handwritten information displayed on the blackboard that is the first to instruct the user to edit or change the attributes. Therefore, it is possible to prevent conflicts between editing and attribute changing operations between a plurality of handheld blackboards.

In the explanation of FIG. 10, "selection request" corresponds to the above-mentioned "selection message", and "permission" corresponds to the above-mentioned "selection message".
``possible message'', and ``rejection'' corresponds to the above-mentioned ``impossible message''. Furthermore, the "editing operation" corresponds to the "execution message" mentioned above, and based on this, the main processing device (common display board)
Perform an edit similar to the one performed in . In addition, since "end of editing" means the end of the editing operation period, it has been explained that the output is output from the blackboard at hand for convenience, but in reality, "end of editing" is output from the main processing device to the sub-processing device.
This corresponds to the "editing completed message".

As explained above, in the handheld blackboard system of this embodiment, the main processing unit is equipped with the management table shown in FIG. 9, and the management table shown in FIG. By performing the processing shown in FIG. 10, the operations when the selection for editing or changing the attributes of the handwritten information displayed on the common display board is instructed from multiple blackboards can be performed without inconsistency. be able to.

(The following is the margin) Next, using Figure 11 (a) and Figure 11 (b),
Another example of the operation when a selection for editing or changing the attributes of handwritten information displayed on the common display board is instructed from a plurality of handwritten blackboards will be described.

FIG. 11(a) is a flowchart showing the flow of operations in an example using a table in which priorities are determined in advance.

1 displayed on the common display board from multiple blackboards
When there is an instruction to edit or change attributes for one piece of handwritten information, the main controller 302 in FIG.
1o1 refers to the priority table. As a result, in step 1102, permission to edit or change attributes is output to the hand-held blackboard with the highest priority among the plural hand-held blackboards. And only the blackboard that has received permission is
In step 1103, the user can edit or change the attributes of the corresponding handwritten information displayed on the common display board.

FIG. 11(b) shows an example of the priority order table 1104.

As shown in FIG. 11(b), each handheld blackboard is assigned a priority order. For example, assume that instructions to edit handwritten information displayed on the common display board are received from blackboard A and B. At this time, the priority order table 1104 is referred to in step 1101 shown in FIG. 11(a).

According to the example of the priority order table 1104, the priority of the handheld blackboard A is "4" and the priority of the handheld blackboard B is "1", so in step 11o2, the common display board is set to the handheld blackboard with the higher priority. A permission to edit is output to B, and a refusal is output to blackboard A at hand. As a result, only the handwritten blackboard B can edit or change the attributes of the corresponding handwritten information displayed on the common display board in step 1103.

As explained above, according to this embodiment, when attempting to edit or change the attributes of handwritten information displayed on the common display board from multiple blackboards, the blackboard with the highest priority is The permission will be output. Therefore, conflicts in editing or attribute changing operations between a plurality of handheld blackboards can be prevented.

Next, using FIG. 12(a) and FIG. 12(b),
The state of the display screen when handwritten information is selected from a certain blackboard will be explained.

In FIG. 12(a), the hand-held blackboard system of this embodiment includes a common display board 1201, hand-held blackboards 1203 and 120.
It is composed of 4. Although the main processing device and the sub-processing device are not shown, the main processing device is displayed on the common display board 1201, and the sub-processing device is displayed on the hand blackboard 1203, 1204.
, respectively.

In the example of FIG. 12(a), handwritten information 1208 is displayed on the common display board 1201, handwritten information 12o9 is displayed on the hand blackboard 12o3, and handwritten information 1207 is displayed on the hand blackboard 1204. That is, the same handwritten information is displayed on the common display board 1201 and each of the handwritten blackboards 1203 and 1204.

Here, it is assumed that handwritten information 1207 is selected from the handwritten blackboard 1202 as an editing target using the input pen 1204. At this time, a marker 1210 indicating that it has been selected is displayed on the hand blackboard 1202. Similarly, the hand blackboard 12
A marker 1212 is displayed on 03, and a marker 1211 is displayed on the common display board 1201. moreover,
Cursor 1205 indicating the current position of input pen 1204
．． 12o6 is the common display board 12o1 and the hand blackboard 120
3 are displayed respectively.

In this state, the selected handwritten information 1207 can be freely edited from the handwritten blackboard 12o2, but the handwritten information 1209 cannot be selected from the handwritten blackboard 1203.

FIG. 12(b) shows the state shown in FIG. 12(a) when handwritten information 1216 is selected from the handwritten blackboard 1203 as an editing target with the input pen 1213.

In FIG. 12(b), handwritten information 121
A marker 1219 indicating that 6 has been selected is displayed on the hand blackboard 1203. Similarly, the hand blackboard 120
2 and a marker 1220 are displayed on the common display board 1201, respectively. Furthermore, a cursor 1214 .indicating the current position of the input pen 1213 .
1215 is the common display board 1201 and the hand blackboard 1202
1 each is displayed.

What you need to be careful about here is that the common display board 12
The handwritten information 1208 displayed on 01 is on the handwritten blackboard 1
This means that the 1 handwritten information 1217 selected by 202 is selected by the handwritten blackboard 1203. This means that different handwritten information can be selected for editing from different handwritten blackboards.

Therefore, when the target selection for editing the information displayed on the common display board or changing the attributes thereof is instructed from a plurality of blackboards at hand, the operations can be performed without contradiction.

Furthermore, as in this first example, a hand-held blackboard system can also be realized with a configuration in which a plurality of hand-held blackboards are connected without providing a common display board. In this case, it is preferable to consider one handheld blackboard as the chairman, and make the processing of the sub-processing device of the handheld blackboard the same as the processing of the main processing device of the common display board, including competition processing. In addition, in such a configuration, if a communication network is interposed between the respective blackboards, it becomes possible to hold a conference between remote locations.

Furthermore, the handheld blackboard system of this embodiment can have a multi-window configuration for the common display board and the display screen of the handheld blackboard.

For example, when the display screen of the common display board has a multi-window configuration, each window can be assigned to the overall common screen and to each handheld blackboard, or to each topic of a meeting.

Furthermore, if the display screen of the hand blackboard has a multi-window configuration, each window can be assigned to a screen that displays the same screen as the common display board and a screen for personal notes.

In the above description, the present embodiment is used exclusively for conferences, but the invention is not limited to this, and can be used for presentations, education, games, and the like.

Further, in this embodiment, the transmission line 407 shown in FIG. 4(a) is wired, but it can be constructed wirelessly by using light, electromagnetic waves, etc. as a medium.

Further, in this embodiment, the information handled is handwritten information, but it is not limited to this, and it goes without saying that it can be applied to various information such as images read with an image scanner etc. and coded characters. All you need to do is prepare a handheld blackboard with a configuration that corresponds to the type of information.

Furthermore, in this embodiment, at least the common display board,
It can be provided with a function to print a hard copy like a conventional electronic blackboard.

In addition, although we have explained that the content displayed on the hand-held blackboard is the same as the content displayed on the common display board, since the sizes of the two devices are different, the content displayed on the hand-held blackboard is the same as the content displayed on the common display board. The content will be reduced.

Therefore, it is difficult to input handwritten information from the handwritten blackboard, so when inputting 1 handwritten information, the content displayed on the handwritten blackboard is a portion of the content displayed on the common display board, and This content is enlarged to a size that allows handwritten input. At this time, it is preferable to provide a scrolling function so that the entire screen can be referred to.

Furthermore, a function may be provided to recognize characters and figures input by hand and convert them into code information, and the content to be displayed on the common display board may be displayed in code information.

Further, a translation function may be provided to convert character code information into character code information of a different language.

[Effects of the Invention] As explained above, according to the present invention, speakers in a meeting can freely edit commonly displayed information from their hands without leaving their seats, thereby improving the progress of the meeting. This has the effect of making it possible to easily perform the following.

Further, according to the present invention, when multiple editing requests for the same information occur, priority is determined, so it is possible to prevent conflicts among multiple editing operations.
