Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention shares an application among a plurality of computers connected to each other through a network and performing distributed processing, such as those employed in a computer remote conference system, a remote desktop presentation system and the like. In addition, the present invention relates to a control method of an application operation right, which controls delivery of the operation right.

[0002]

2. Description of the Related Art Computers operating according to their own programs are connected via a network,
A computer remote conference system and the like are realized by sharing a specific application. In that case, the participants share the same application while looking at their respective displays. In such a system,
Only one of the participants is given the operation right of the application, and by exchanging the operation right, all the participants operate the same application.
In order to adjust the competition of the operation right in such a case, for example, the participant clicks the operation right request button displayed on the display to add the operation right to the end of the operation right request queue. When the participant who already has the operation right clicks the operation right abandon button, the operation right is transferred to the first person in the operation right request queue. Such a technique is described in the following documents, for example. ““ XTV: A Framew

[0003]

By the way, the above-mentioned conventional control method of the application operation right has the following problems to be solved. The conventional operation right competition adjustment method as described above is suitable for the case where the form of the work of the application operation is modeled. However, in a wide variety of application sharing systems,
Further flexibility is required for the transfer control of the operation right. Therefore,
For example, if the operation right is requested, a method of immediately giving the operation right can be considered. However, this may cause an adverse effect because the operation right may be transferred unconditionally to another participant during the operation of the participant who has the operation right. In addition, a method in which a participant who has the operation right inputs whether or not the operation right can be delivered when the operation right is requested. However, such a method is relatively complicated and complicates the procedure for transferring the operation right, which hinders smooth cooperative work. There is also a method in which the operation right cannot be moved within a fixed time from the last operation input, and anyone can obtain the operation right after the fixed time. However, even in this case, since the machine completely controls the operation right, even if the humans can agree with each other, the operation right cannot be passed, and all the participants may feel uncomfortable.

[0004]

The present invention adopts the following constitution in order to solve the above problems. Among multiple participants who share the same application while looking at different displays, if any one participant acquires the operation right of the above application, each display has the operation right of the participant. The operation right window that displays is displayed, and this operation right window displays which participant has the operation right, and includes the operation right button for performing the operation right acquisition operation. The position of the mouse pointer displayed in the user's application window is detected, and the current pointer distinguishable from the user's own mouse pointer is displayed at the corresponding position in the application window of the participant who does not have the operation right.

According to another method, among the plurality of participants who share the same application while looking at the respective displays, one of the participants acquires the operation right of the above-mentioned application. In addition to displaying the mouse pointer of the participant, the position of the mouse pointer displayed in the application window of the participant who has the operation right is detected, and at the corresponding position of the application window of the participant who does not have the operation right, The current pointer that can be distinguished from the own mouse pointer is displayed, and the current pointer is set as the operation right button for acquiring the operation right.

[0006] Further, in another method, among the plurality of participants who share the same application while looking at the respective displays, any one of the participants acquires the operation right of the application. Displays an operation right window that displays whether or not the participant has the operation right. In this operation right window, which participant has the operation right is displayed and the operation right is forcibly acquired. The participant's mouse pointer is displayed on each display, including the compulsory button to detect the position of the mouse pointer displayed in the application window of the participant who has the operation right In the corresponding position of the application window of, the current pointer that can be distinguished from its own mouse pointer Shows, by setting the operation right selection button for performing an operation right acquisition operation the current pointer, when the forced button is operated, the moving speed of the current pointer is limited to below the set value.

Further, the following method is a method in which any one of a plurality of participants who share the same application while looking at different displays acquires the operation right of the application. In addition to displaying the mouse pointer of the participant, the position of the mouse pointer displayed in the application window of the participant who has the operation right is detected, and at the corresponding position of the application window of the participant who does not have the operation right, The current pointer that can be distinguished from the own mouse pointer is displayed, the position of the mouse pointer displayed in the application window of the participant who does not have the operation right is detected, and the position corresponding to the application window of the participant who does not have the operation right is detected. Teleport that can be distinguished from the participant's mouse pointer Display pointer, participants with operation right is, when operating the tele pointer corresponding to the mouse pointer other participants, the operation right to move to the other participants.

When a plurality of windows are displayed on the display, each operation right window may be pasted on the application window which is the operation right control target. In addition to this, when a plurality of windows are displayed on the display, when the operation right window pasted on any of the application windows is operated, the application window can be displayed in the foreground. Also, when multiple windows are displayed on the display, each operation right window is pasted on the operation right control target window, and the operation right window can be freely set inside the control target application window. It may be movable.

[0009]

For example, assume that the document window of the application to be shared is displayed on the display of the participant A. An operation right window for the document application is attached to this document window. This operation right window includes an operation right button for acquiring the operation right and a compulsory button forcibly acquiring the operation right. The mouse pointer operated by the participant A is displayed as the current pointer in the document window of the participant B. Thereby, the operation of the participant A can be easily recognized by the participant B.

The operation right button displayed in the operation right window is composed of, for example, an icon and is operated by clicking a mouse or the like. Further, the current pointer is displayed so that a participant who does not have the operation right can know the action of the participant who has the operation right. Furthermore, by clicking the current pointer, the operation right is acquired by the clicker. As a result, the operation right can be transferred when the current pointer does not move, that is, when the person having the operation right has stopped the operation. Even if the person having the operation right is operating and the current pointer is moving, clicking the force button suppresses the movement of the current pointer, that is, the mouse pointer of the person having the operation right. In this way, a means for obtaining the operation right can be provided. The setting value of the moving speed is low enough to click the current pointer or is in a stopped state.

By displaying a telepointer indicating the position of the mouse pointer of the participant who does not have the operation right in the application window of the participant who has the operation right, and the participant who has the operation right clicks an arbitrary telepointer, It is also possible to voluntarily transfer the operation right to other participants. By sticking the operation right window on the window to be the operation right control target, the object of the operation right transfer is clarified, and the interface for controlling the operation right can be simplified. Note that the operation right window can be freely moved to the application window and does not prevent the application from being referenced.

[0012]

The present invention will be described in detail below with reference to the embodiments shown in the drawings. [Outline of Display Display of Participants] FIG. 1 is a diagram showing an embodiment of the present invention. In this example, two participants A and B share the document application and the table application by using the application sharing system.
In the figure, the display contents of the display 10 of the participant A and the display 20 of the participant B are shown. A document window 11, a table window 12, a mouse pointer 13 of the participant A, a document application operation right window 14, a table application operation right window 15, and a figure window 16 are displayed on the display 10 of the participant A. Further, on the display 20 of the participant B, the document window 21, the table window 22, the mouse pointer 23 of the participant B, the operation right window 24 for the document application, the operation right window 25 for the table application,
The current pointer 26 for the document application is displayed.

Document window 11 and document window 21
The table window 12 and the table window 22 are display windows of applications shared among the participants AB in the application sharing system. Therefore, the document window 11 and the document window 21, and the table window 12 and the table window 22 respectively display the same contents. Although the display contents of the respective windows are the same, the participants can freely change the positions of the windows, so that the display arrangement of the participant A and the display 20 of the participant B have different window arrangements.

The mouse pointer 13 of the participant A and the mouse pointer 23 of the participant B are the mouse pointers of the respective participants. Since each participant can freely move the mouse pointer independently, the display positions of the mouse pointers 13 and 23 on the display 10 of the participant A and the display 20 of the participant B are different. The figure window 16 is a window of an application which the participant A uses alone without sharing it among the participants AB. Therefore, it is not displayed on the display 20 of the participant B.

[Operation Right] Here, it is assumed that the participant A has the operation right for both the document application and the table application. The operation right is a right to operate the application at that time.
Only one person can operate the application at each time point, but by exchanging this operation right, all the participants can operate the application. The document application operation right window 14, the table application operation right window 15, the document application operation right window 24, and the table application operation right window 25 are used by the application sharing system as application windows for the operation right handing operation. It is the operation right window that is pasted. Each participant can freely change the position of the operation right window within the display window of the target application. Therefore, the display positions of the document application operation right windows 14 and 24 are different between the display 10 of the participant A and the display 20 of the participant B.

FIG. 2 is a diagram showing a display example of the operation right window. As shown in FIG. 2, the document application operation right window includes an operation right button 30, a compulsory button 31, and a moving bar 32. The table application operation right windows 15 and 25 have the same structure,
Here, the operation right window for the document application will be described as an example. The operation right button 30 is a button used to display the state of the current operation right and to obtain a new operation right. The display content of the operation right button 30 changes depending on the situation.

FIG. 3 is an explanatory view of another display example of the operation right window. The operation right button 30 displays the name of the operation right holder as shown in FIG. 3 when the mouse pointer of the operation right holder of the target application is in the window of the target application. At other times, an arrow having the same shape as the current pointer is displayed as shown in FIG.

The above judgment can be realized by an application sharing system having a current pointer display function which will be described later. If the operation right button 30 is indicated by an arrow and the operation right button 30 is clicked, the operation right is obtained. When the operation right button 30 is clicked when the name of the operation right holder is displayed, since the operation target is the document application, the document window 11 or 21 in which the current pointer 26 for the document application is displayed is displayed. Move to the front. Force button 31
Is a button used to forcibly take away the operating right. The moving bar 32 is used when changing the display position of the operation right window.

The document application current pointer 26 shown in FIG. 1 is the current pointer of the document application. This current pointer indicates the position of the mouse pointer of the participant A who has the operation right for the document application. That is, as shown in FIG. 1, the same position as the position of the mouse pointer 13 of the participant A in the document window 11 is set to the document window 21 of the participant B.
The current pointer 26 for the document application is displayed in order to notify the participant B within. This function can be realized by an application sharing system having a current pointer display function described later. In this example, in order to improve the operability, the operation right can be obtained by clicking the current pointer 26 for the document application.

[Application Sharing System] FIG. 4
FIG. 3 is a block diagram showing an embodiment of an application sharing system for controlling the current pointer and window display. The application sharing system in the figure is
It is composed of a pseudo server 51, a master server 52, a client 50, and slave servers 53 and 54. Current pointer processing units 56-1 to 56-3 are connected to the servers 52 to 54, respectively. Pseudo server 51
Is a unit that distributes protocols for application sharing. The master server 52 and the slave servers 53 and 54 are machines for controlling the X server program of the X-Windows system, for example. The master server 52 and the slave servers 53 and 54 may be completely functionally equivalent, and here, the window system which appears to be directly connected to the client 50 is called the master server 52, and Other window systems than slave servers 53, 5
I call it 4. The master server 52 provides a window environment at the request of the client 50. The window environment is an operation screen of an application, which is controlled by the master server 52.

The client 50 is a target of sharing,
For example, a stand-alone application for the X-Windows system. This may be a general application for that window system. The document windows 11 and 21 and the table window 1 shown in FIG.
The application that controls 2, 22 is also this client. The network 57 is a network that connects each machine to form a distributed machine environment.

The current pointer processing unit 56-1 is a unit for realizing the current pointer display function,
As shown in the lower side of the figure, the control unit 61 and the pointer processing unit 6
2, a window management unit 63, a communication management unit 64, and a user interface 65. The control unit 61 is a unit that performs basic processing for the current pointer processing unit 56-1.

The pointer processing unit 62 is a unit for detecting the position of the mouse pointer 13 and displaying the current pointer 26 shown in FIG. The window management unit 63 is a unit for managing windows to be shared.
The communication management unit 64 is a unit that manages communication with the pseudo server 51. The user interface 65 is a unit that manages the user interface.

The pseudo server 51 is a central part for realizing sharing of a stand-alone application in a distributed machine environment. The programs of the pseudo server 51, the master server 52, the slave servers 53 and 54, and the client 50 are all independent processes, and no matter which process runs on which machine in the distributed machine environment connected by the network, There is no problem at all.

Next, the operation of the application sharing system will be described. Before executing the application sharing system, it is assumed that the user uses the X-Windows system and uses a general application. Therefore, the master server 52 and the slave servers 53 and 54 are already operating. here,
When it becomes necessary to share an application among a plurality of users, the pseudo server 51 is activated to operate the application sharing system. When activating the pseudo server 51, the pseudo server 51 is notified of which users share the application by using the server name used by each user. When activating the application to be shared, that is, the client 50, the pseudo server 5
Specify 1 as the server and start it. Client 50
When activating, the pseudo server 51 receives a connection request from the client 50 and distributes the connection request to the master server 52 and the slave servers 53 and 54. In a general X-Windows system, a server that receives a connection request from a client sends back server information. Now, when viewed from the master server 52 and the slave servers 53 and 54, since the pseudo server 51 corresponds to the client, the server information is sent back to the pseudo server 51.

Next, the pseudo server 51 records the server information of each server and sends the server information returned from the master server 52 to the client 50. After that, the client 50 operates by sending a request such as window creation to each server based on the received server information. The pseudo server 51 performs protocol conversion and distribution of the request sent by the client 50.

That is, the client 50 is originally created as a stand-alone application,
Having received the server information of the master server 52, the client 50 is sending out a request for the master server 52. Where slave server 5
In order to create the same window in 3 and 54 and share the application, the pseudo server converts this request for each slave server 53 and 54 based on the server information stored at the time of starting the client, and the slaves -Distribute to the servers 53 and 54.

On the other hand, from each server 52 to the client 50
The event sent to is converted in the reverse order of the request distribution, converted like the event from the master server, and sent to the client 50. The pseudo server operates in this way.

Next, the operation of the current pointer processing section 56-1 will be described by taking the display / non-display operation of the current pointer as an example. When the current pointer processing unit 56-1 has the operation right, the current pointer processing unit 56-1 transmits a current pointer display command or a current pointer non-display command to the other current pointer processing units 56-2 and 56-3 through the pseudo server 51,
If there is no operation right, another current pointer processing unit 56-
The current pointer display command or the current pointer non-display command sent from 2 or 56-3 through the pseudo server 51 is received, and the display or non-display of the current pointer is controlled according to the content of the command.

FIG. 5 and FIG. 6 are flow charts of the current pointer display control operation. First, the operation when transmitting the current pointer display instruction or the current pointer non-display instruction when there is an operation right will be described with reference to FIG. The first process is performed by the control unit 61. Step S
At 1, one client to be processed is determined. When dealing with multiple clients, try changing the target client in order. In step S2, it is checked whether the target client has the operation right. If the user has the operation right, the process proceeds to step S3. If not, the process ends.

In step S3, the control unit 61 passes the client identifier of the target client to the window management unit 63. The window management unit 63 uses the client identifier to determine the window I of the window created by the client.
D is selected and passed to the pointer processing unit 62. Step S4
Then, the pointer processing unit 62 investigates the current position of the mouse pointer and the window ID of the currently invading window. This can be accomplished by querying the window system.

In step S5, it is checked whether or not the mouse pointer is in the window of the target client. This is performed by comparing the window ID selected by the window management unit 63 and the window ID currently invaded by the mouse pointer checked in step S4.
If there is a mouse pointer in the window,
Go to step S7. If there is no mouse pointer in the window, the process proceeds to step S6. In step S7,
The relative position of the mouse pointer in the window is calculated from the current position of the mouse pointer and the intruding window ID checked in step S4.

In step S8, the client identifier, the window ID, and the relative coordinates within the window are transmitted to the pseudo server 51 as a current pointer display command.
When it is finished, the process ends. In step S6, the current pointer non-display instruction is transmitted to the pseudo server 51.
When it is finished, the process ends. The above is the operation of the current pointer processing unit 56-1 when there is the operation right.

The operation of the pseudo server 3 will be described with reference to FIG. Step S1 corresponds to a normal process of the pseudo server 51. In step S2, it is checked whether a window has been created. If so, step S3
If not, move to step S4. Step S
In step 3, the window ID of the created window is checked, and this is used as the newly created window ID and notified to the current pointer processing unit 56-1 together with the identifier of the client who created the window. If the window ID created for each server is different, check the window ID created for each window system, and create the window ID and window in the current pointer processing unit 56-1 connected to each window system. The identifier of the client that made the notification. This is stored in the window management unit 63. When the notification of the window ID is completed, the process proceeds to step S13.

In step S4, it is checked whether a current pointer display instruction or a current pointer non-display instruction has arrived from the current pointer processing section 56-1. If it has arrived, move to step S5, and if not, S7
Move on to. Step S5 is a process necessary when the window ID created for each server is different. The window ID in the current pointer display command is converted into the corresponding window ID of the server connected to the current pointer processing unit 56-1. Nothing is done for the current pointer non-display instruction. When the processing is completed, the process proceeds to step S6.

In step S6, the current pointer display command or the current pointer non-display command is distributed to all the current pointer processing units other than the current pointer processing unit 56-1 that has transmitted the current pointer display command. At this time, if necessary, the value of the window ID in the command is set in step S
Use the value converted in 5. When the processing is completed, the process proceeds to step S7. In step S7, it is checked whether or not the operation pointer acquisition report has arrived from the current pointer processing unit 56-1. If it has arrived, the process proceeds to step S8, and if not, the process returns to S1. In step S8, the fact that the operation right is lost is notified to the current pointer processing unit 56-1 that has the operation right until now. When the process is completed, the process returns to S1.

Now, the operation of the current pointer processing section 56-1 when there is no operation right will be described. When there is no operation right, the current pointer processing unit 56-1 controls the display of the current pointer according to the current pointer display command or the current pointer non-display command sent from the pseudo server 51. When the current pointer display instruction is received, the window ID of the instruction content and the relative coordinates within the window are used to display the current pointer at the position indicated by the relative coordinates within the window of the window ID. When the current pointer non-display instruction is received, the current pointer is not displayed until the next current pointer display instruction is received. With these, the display function of the current pointer is realized.

[Movement of Operation Right] Returning to FIG. 1 again, an operation method when the participant B obtains the operation right of the table application will be described. In the state of (a), the participant A has the operation right of the table application, but the mouse pointer 13 of the participant A is not in the table window 12. That is, the participant A is not currently operating the table application. At this time, the display 2 of the participant B
An arrow is displayed on the operation right button 30 in the 0 operation right window for application 25. As a result, Participant B can know that Participant A is not operating the table application, and now knows that there is no problem in acquiring the operation right for the table application. The operation right can be obtained by pressing the operation right button 30 shown.

Next, an operation method for obtaining the operation right of the document application will be described. The method of obtaining the operation right can be roughly divided into two methods, which will be described in order.
First, the first method is a method in which the participant B obtains the operation right at his own discretion. The operation authority of the document application is (a)
As shown in FIG. 5, the participant A has the mouse pointer 13 of the participant A in the document window 11. Therefore, the document window 2 of the display 20 of the participant B
A current pointer 26 for the document application is displayed in the area 1. Participant B can know the operation status of participant A who has the operation right from the movement of the current pointer 26 for the document application. For example, if the text application current pointer 26 remains stationary and characters are not input, the participant A can determine that the text application is not being operated, and the text application current pointer 26 is active. If you are moving to, you can determine that you are operating the application. When the participant B determines that the participant A may take the operation right of the document application, the participant B may click the current pointer 26 for the document application to obtain the operation right.

As a result, it is possible to prevent the mistake of picking up the operating right without confirming "whether the participant who has the operating right is operating".
This is because it is necessary to click the current pointer 26 for the document application in order to obtain the operation right, and inevitably the movement of the current pointer 26 for the document application will be seen. This is because it is not easy to click the for-current pointer 26.

When it is necessary to take up the operation right after knowing that the participant A having the operation right is operating the application, the compulsory button 3 shown in FIG.
Use 1. When the compulsory button 31 is clicked, the movement of the current pointer 26 for the document application is stopped or the movement of the current pointer 26 for the document application is slowed down.

As a result, the current pointer 26 for the document application can be easily clicked, and the operation right can be taken up. This operation is different from the case where you take the right to operate,
There is no problem because it is done with the intention to forcefully take up the operation right. If this operation causes a problem, it is not a problem of the application sharing system or the operation method of the operation right transfer, but a problem that occurs in the communication between human beings. The moving speed of the current pointer 26 for the document application, which is slowed down by the click of the compulsory button 31, returns to the original speed due to the movement of the operation right or the lapse of a certain time.

The second method is a method in which the participant B requests the operation right from the participant A who has the operation right, and when the participant A responds to the request, the operation right is transferred to the participant B. Now, it is assumed that this application sharing system has a telepointer function and a voice communication function. The voice communication function does not have to exist as a function of the application sharing system. For example, by using a telephone call or a voice communication system together, the voice communication of the participants can be performed.

The telepointer makes the position pointed to by one participant visible to other participants. This can be realized by the application sharing system having the current pointer display function as shown in FIGS. That is, the current pointer always informs the other participants of the operation status of the application of the participant who has the operation right, while the telepointer conveys the intention of the participant. Therefore, it can be realized by displaying the pointer in the same manner as the current pointer only when the participant instructs the display of the telepointer. Further, here, when the participant who has the operation right clicks the telepointer, the operation right is passed to the owner of the telepointer.

The operation for obtaining the operation right will be described with reference to FIG. FIG. 7 shows the display 10 of the participant A and the display 20 of the participant B similarly to FIG. On the display for participant A, the telepointer 1 of participant B is displayed.
7 is added, and the telepointer 27 of the participant B is added to the display 20 for the participant B. The telepointer 17 of the display 10 is a telepointer indicating the place where the participant B is pointing. The telepointer 27 of the display 20 is a telepointer for the participant B to point to a place.

First, the participant B uses the telepointer 27 to request the operation right. However, the actual operation may be movement of the telepointer 27. However, the fact that the operation right is requested is communicated by voice to the participant A who has the operation right. At this time,
The telepointer 27 is displayed near the current pointer 26. Since the participant A who has the operation right generally looks around the mouse pointer 13 of the display 10, if the participant B requests the operation right by voice, the participant A immediately B tele pointer 17
You should notice. Here, if the participant A who has the operation right decides that the operation right may be given to the participant B, the tele pointer 17 of the participant B is clicked to give the operation right to the participant B. Good. If you do not want to give the operating right, you can decline by voice.

The operation of moving the window with the current pointer to the foreground will be described with reference to FIG. When one application has a plurality of independent windows, or when a plurality of windows are displayed in an overlapping manner, it may be difficult to find the current pointer. In such a case, the operation right handing operation can be comfortably performed by moving the window with the current pointer to the foreground.

FIG. 8 shows an example in which the current pointer 26 for the document application cannot be seen on the display 20 of the participant B. The figure shows the display 10 of participant A and the display 20 of participant B as in FIG. The display 10 has a document auxiliary window 18,
The operation right window 19 for the document auxiliary window is added,
A document auxiliary window 28 and a document auxiliary window operation right window 29 are added to the display 20, and the drawing window 16 of the display 10 is iconified.
It is the icon 16A of the drawing window. The document auxiliary window 18 is an auxiliary window for a document application. Operation right window 1 for document auxiliary window
Reference numeral 9 is an operation right window of the document auxiliary window 18. The document auxiliary window 28 is an auxiliary window for a document application. The document auxiliary window operation right window 29 is an operation right window of the document auxiliary window 28.

As described above, when one application has a plurality of independent windows, the operation right window is attached to each independent window. This is to clarify the correspondence between the application window and the operation right window and improve the operability.
The display contents of the operation right window should always be the same for the same application. The current pointer 26 for the document application should be displayed on the document window 21 of the display 20, but the display is not visible because the document auxiliary window 28 overlaps with it. At this time, the operation right button 30 of the operation right window 24 for the document application or the operation right window 29 for the document auxiliary window is clicked to move the window in which the current pointer 26 for the document application is displayed to the front. To do. FIG. 9 shows an explanatory diagram of the result of the operation. As a result, the current pointer 26 for the document application
Can be operated.

The present invention is not limited to the above embodiments. The mouse pointer can be operated not only by a mouse but also by various pointing devices such as a pressure-sensitive panel-shaped pointing device, a digitizer, and a trackball.

[0051]

According to the method of controlling the application operation right of the present invention described above, the following effects can be obtained. (1) In order to obtain the operation right, it is necessary to see the movement of the current pointer inevitably, so the operation right is taken up without confirming "whether the participant who has the operation right is operating". That mistake can be prevented. As a result, the collaborative work will not be hindered by the confusion caused by the operation error transfer operation. (2) If the request for the operation right is shared with the display of the telepointer, the participant does not need to newly learn the operation for requesting the operation right. (3) If you see the display of the operation right button in the operation right window,
You can immediately see if the operation right is used and who is using the operation right. (4) If the operation right window is pasted to the application window, the operation right window can be comfortably operated without having to search for the operation right window or move the mouse pointer further than necessary in order to pass the operation right. (5) It is possible to forcibly take up the operation right after knowing that the participant who has the operation right is operating the application. (6) Since the computer only informs the participant of the situation and the participant is left to decide whether to take the operation right or not, it is possible to freely operate according to the form of the cooperative work.
