S120 applies for the element lock of object element if the target of the action event is page elements；

Wherein, object element is the page elements that current operation event is directed to.

With continued reference to shown in Fig. 3, white board writing region entirety can be understood as the blank page, write the pen shown in region Mark, image etc., then can be understood as page elements；Wherein person's handwriting can be text handwriting, be also possible to symbol or other What person's handwriting.The target of action event is that page elements refer to that user wishes that the object of operation is a part of element in the page, But it is not page itself, such as: for user when writing on blank, the target of write events is the person's handwriting increased newly in the page, therefore Its corresponding target is page elements；When user deletes original figure in the blank page, the target of deletion event is in the page Figure person's handwriting, therefore its corresponding target is page elements；When user moves the figure in the page, the mesh of moving operation event The figure being designated as in the page, therefore its corresponding target is page elements；When user amplifies the figure in the page, thing is enlarged The target of part is the figure in the page, therefore its corresponding target is page elements；When user drags the page, drag operation event Target be the page, therefore its corresponding target is then the page.

S130 shows the operating result to object element in the first blank after applying for the element lock to object element.

It should be noted that the page member that the action event that the only described object element is not belonging to the second blank is operating In the case where element, it could apply for that the element to object element is locked.

Wherein, the element lock of element can be understood as weighing the EXCEPT operation of the element, in the embodiment of the present invention, with for the moment Between put the element locks of each page elements and be only capable of a blank user being assigned in shared meeting, such as: participate in it is identical Element 1 and element 2 are shown on the first blank and the first blank of shared meeting, if current first blank user applies obtaining The element of element 1 is locked, then the element lock based on element 1, and the second blank user will be unable to carry out any behaviour to the element 1 at this time Make；If the element lock of element 2 is unassigned at this time, the second blank user has an opportunity to obtain the element lock of element 2, obtain at In the case where function, then the second blank user can operate element 2, at this time the first blank user then can not to element 2 into Any operation of row；It is thus achieved that the first blank and the corresponding multiple users of the second blank can be simultaneously to different page members The effect that element is operated；Since just start element is write after terminating without waiting for other users operation, operation effect is improved Rate is conducive to improve shared effect of meeting.

In one embodiment, object element is not belonging to the page elements that the action event of the second blank is operating, comprising: The page lock of the page where object element, the element lock of object element are not allocated to the second blank.I.e. object element is current Not by other blank user's operations, operation is avoided to conflict with this.

In one embodiment, the operating result that action event described in step S130 generates includes with the next item down or more : page elements increase, page elements are reduced, position of page element variation, page elements metamorphosis.

In addition, it is additionally provided with the mechanism of page lock under the mechanism of above-mentioned element lock, accordingly, refering to what is shown in Fig. 4, In one embodiment, blank operating method in above-mentioned shared meeting can with comprising steps of

S140 applies for the page lock of target pages if the target of the action event is the page；The target pages are institute State the page that the first blank is shown when action event occurs.

S150 shows the operation knot to target pages in the first blank after application obtains the page lock of target pages Fruit.

It should be noted that the action event that only target pages are not belonging to the second blank operating the page the case where Under, it could apply for that the page to target pages is locked.

Wherein, the page lock of the page can be understood as the EXCEPT operation power to the page.The page the page lock with it is above-mentioned The element locking phase ratio of element, granularity is bigger, and specific difference includes: when any one blank user applies obtaining one in shared meeting When the element lock of a element, other blanks user can also operate the other elements except the element in the blank page； However, when any one blank user obtains the page lock an of page in shared meeting, other blanks user would not allow for into Any operation for the page of row and the operation for element in the page.That is, the page of the page is locked under the state of being assigned, An only user can operate the page in shared meeting, do not support more people while carrying out blank operation.

In one embodiment, target pages are not belonging to the page that the action event of the second blank is operating, comprising: target The element lock of each element is not allocated to the second blank in the page lock and target pages of the page.I.e. target pages are not currently By other blank user's operations, operation is avoided to conflict with this.

In one embodiment, the operating result that action event described in step 150 generates includes following one or more: Page movement, page zoom-in and zoom-out, page page turning.

By the way that element lock and page lock is respectively set, for different blank action events, varigrained lock can be carried out Fixed, on the one hand more people carry out blank operation simultaneously in convenient shared meeting, and another aspect avoids issuable behaviour each other Work conflicts.

Further, in order to guarantee shared effect of meeting, in some embodiments, the blank behaviour in above-mentioned shared meeting It is further comprised the steps of: as method

Apply obtaining page object after the element lock of the first blank end application to object element, or at the first blank end After the page lock in face, the operating result that the action event shown in the first blank generates is synchronized to and participates in identical shared meeting The second blank, be achieved in participate in identical shared meeting blank show content synchronization.

Referring to above-mentioned, the operating result that the action event in the step generates may include following one or more: page Surface element increase, page elements reduction, position of page element variation, page elements metamorphosis, page movement, page zoom-in and zoom-out, Page page turning.

It should be noted that the second blank and the first blank, cannot be the blanks installed in the same interactive intelligent tablet computer Using can not be the same interactive intelligent tablet computer in blank mode itself.

In some embodiments, it realizes the mode of content synchronization between blank in shared meeting for example: obtaining the first blank The blank content of middle variation；The blank content of the variation is generated by the action event；The blank changed is sent to server The corresponding content-data of content, so that the second blank obtains the content-data by server, so that the second blank is white Same change occurs for plate content.Due to the relevant information for the blank content that the first blank, the second blank are only changed Transmission, obtain, alleviate the data transmit-receive amount of the first blank, the second blank, advantageously ensure that the first blank, the second blank are aobvious Show the time synchronization of content.

Specifically, for being directed to the action events of blank page elements, content synchronization is shared in meeting between blank for example: (1) first blank, the content of pages of the second blank are identical (be sky, or be identical content of pages), then detect The page elements of first blank increase, and obtain increased page elements data, send it to the second blank, the second blank is in original On the basis of some content of pages, increased page elements on the first blank are further displayed out；(2) first blanks, the second blank Content of pages it is identical, then detect the first blank page elements reduce, obtain reduced element data, send it to Second blank, the second blank reduce same page elements on the basis of original content of pages；It is (3) first blanks, second white The content of pages of plate is identical, then detects that certain element position moves in the first blank, obtains the mobile message of the element, The second blank is sent it to, the second blank moves equally corresponding element in original content basis.

Specifically, for being directed to the action event of element, content synchronization is shared in meeting between blank for example: (1) first Blank, the content of pages of the second blank are identical, then detect the page movement of the first blank, obtain the mobile message of the page, The second blank is sent it to, the second blank carries out the movement of equal proportion to local page；(2) first blanks, the second blank Content of pages is identical, then detects the page zoom-in and zoom-out variation of the first blank, obtains page zoom-in and zoom-out change information, send it to Second blank, the second blank carry out the scaling processing of equal proportion to the local page；The page of (3) first blanks, the second blank Content is identical, then detects the page page turning of the first blank, obtains page page turn information, sends it to the second blank, the Two blanks execute the identical page page turning on the basis of original page.

It is understood that few examples of the said circumstances as just content synchronization between blank in shared meeting, no It should be understood as the restrictive interpretation of content synchronization between blank in shared meeting.

In addition, can be detected by blank main program during the realization of content synchronization between blank in shared meeting Blank content on first blank changes, for example, user write operation or user to original in writing region The content of writing has carried out erasing operation, and the blank content that blank main program all can be detected on the first blank changes.It is white Plate main program can obtain the corresponding content-data of blank content to change on the first blank, content-data be transferred to preset Software module is transmitted content-data to the second blank by the software module, the second blank by corresponding software module, Content-data is parsed, is reduced to the content-data that the second blank main program can identify, and then the second blank main program can be passed through It controls the blank content that the second blank is shown and identical variation occurs.

In some embodiments, realize that the mode of content synchronization between blank in shared meeting can be with are as follows: obtain first The screenshotss information of blank sends the screenshotss information to server, so that the second blank obtains described cut by the server Shield information, so that second blank shows the screenshotss information.

It is specific for example, detecting that the first blank application obtains the page lock of the element lock or target pages of object element It later, include the first blank current page in the screenshotss information according to the screenshotss information of the first blank of setting time interval acquiring All information, screenshotss information is sent to server, and then realize and show the same of content between the first blank and the second blank Step.

Blank operating method through the foregoing embodiment, when there is multiple blanks to be participated in a shared meeting jointly, The content of pages variation that the action event of more people or a people on any blank causes, can obtain same on other blanks Step display, such as local participant have write passage on local blank, and distal end participant passes through distal end blank book Another passage is write, then it can be seen that both ends text, solves in original shared meeting on local blank and distal end blank Multiple blanks further improve effect of meeting the problem of not supporting more person writings at same time point.

Further, in embodiment, in order to improve the participations of conference users, the element lock or target of object element The page the page lock not is specific to some blank user, when enjoy object element element lock or target pages the page At the end of the respective operations event of the blank user of lock, the element lock of the object element or the page of target pages will be actively discharged Face lock.Correspondingly, with continued reference to shown in Fig. 4, in one embodiment, sharing the blank operating method in meeting can also include step It is rapid:

S160 sends element to server and unlocks Shen at the end of detecting the corresponding action event of above-mentioned object element Please.

Wherein, the component identification of object element can be carried in element unlock application；It can by element unlock application The element lock of object element is reset to unallocated state with trigger the server.When the element lock of element is set as unallocated After state, any blank user can apply for the element lock of the element in shared meeting.

S170 sends the page to server and unlocks Shen at the end of detecting the corresponding action event of above-mentioned target pages Please.

Wherein, the page iden-tity that target pages can be carried in page unlock application is locked due to the page of the page Exclusiveness can also carry the identification information of the first blank in page unlock application.Application triggering clothes are unlocked by the page The page lock of target pages is reset to unallocated state by business device.When the page the page lock be set as unallocated state it Afterwards, the page lock of the page can be applied for by sharing any blank user in meeting.

In some instances, the blank operating habit based on general user is detecting the corresponding user hand of action event Refer to when perhaps lettering pen leaves blank or leave blank up to when setting duration, then can be determined that terminates for the action event.Example It such as,, can be with when detecting that user's finger or lettering pen left blank up to 1 second for the action event write on blank It is determined as that the writing action event terminates；For the action event in the scaling blank page, detecting that it is white that user's finger is left When plate, it is possible to determine that terminate for the zoom operations event.

By the page lock of timely freeing of page or the element lock of element, multiple users of convenient shared meeting are participated in In blank operation, while the operation conflict between avoiding.

It should be noted that in embodiment, the first blank, the second blank are used only for the differentiation of object, should not manage Solution has equally been able to solve original for example, the first blank, the second blank can also mutually exchange identity to limit the identity of object There are in shared meeting multiple blanks the problem of not supporting more person writings at same time point.

In addition, above-described embodiment mainly shares the blank operating method in meeting from the first blank angle introduction, first is white Corresponding second blank of plate, can be one, can also there is multiple second blanks, be participated in identical shared meeting jointly.

In addition, when first blank itself is as the server for sharing meeting, the first blank and service in above-described embodiment Interacting message between device, which can then correspond to, to be adjusted in the first blank processing locality, without receiving and dispatching relevant information by network.

Further, on the basis of the above embodiments, by taking local blank, server and distal end blank as an example, from more The realization process of the blank operating method in shared meeting is illustrated in the mutual angle of top-cross.Wherein, local blank and Distal end blank can be interactive intelligent tablet computer, whiteboard applications are equipped in interactive intelligent tablet computer, and whiteboard applications are front end Operating status.Under the scene, below with reference to Fig. 5, Fig. 7 is combined, pass through two examples to the blank operation side in shared meeting Method is introduced.

Example 1: page elements action event

L1 detects write events in local blank side (below for writing element S 0).

L2 generates the component identification of object element S0, and the lock application of element S 0 is sent to the server.

Wherein, component identification can be element ID, and in the same blank page, the ID of each element has uniqueness.

It should be noted that for a person's handwriting, blank is that upper erasing mode can be wiped a little and be wiped with line, and it is exactly to wipe that point, which is wiped, Except certain some point therein, and line wiping is that direct whole lines are all deleted.Point wiping mode may cause a person's handwriting be divided into it is more A subsegment for each subsegment, can generate corresponding element mark respectively as a new element in some embodiments.

The component identification of object element S0 can be carried in element lock application；It can be touched by element lock application Whether hair server is assigned according to the element lock that component identification inquires object element S0, if it is not, by the element of object element S0 Lock distributes to local blank, and applies for successful message to the operation lock that local blank sends the object element S0.

In some embodiments, also need to carry the page iden-tity of target pages in element lock application；Pass through element Whether the page lock that lock application can inquire first target pages with trigger the server according to page iden-tity is the state that is assigned, if No, whether the element lock for further inquiring object element in target pages is assigned.Thus not same page can both be accurately distinguished The element lock of element in face, but whether the page where can checking object element is being operated by other users.

L3 receives the element for element S 0 that local blank is sent and locks application in server-side.

L4, according to the component identification that carries in element lock application, the page lock of the page where inquiry object element S0 and Whether the element lock of object element S0 is assigned, if be it is no, the element of object element S0 lock is distributed into local blank.

In some embodiments, the meeting of the shared meeting can also be carried in the element lock application that blank is sent Code；Element lock application in this way can save the element lock distribution letter of the corresponding element of the conference code with trigger the server Breath.I.e. when there are multiple blank end subscribers while carrying out element operation, conference code pair can be saved simultaneously in server end The element lock distribution information for the multiple elements answered.

L5: the operation lock for sending object element S0 to local blank applies for successful message.

In the present embodiment, due to write operation for element S 0 be to need newly-increased page elements, current page not In the case where locked, then this increases the corresponding element lock of element newly and necessarily belongs to unassigned state, therefore local blank can be with Shen It please arrive the element lock of element S 0.

In some embodiments, after the element that server receives object element is locked, the page where first inquiring object element Page lock whether be assigned, if it is not, whether the element lock for inquiring object element again is assigned, the page only where object element Page lock and object element element lock it is unassigned in the case where, the element lock of object element is just distributed into initiation The local blank of application.I.e. if currently having user carrying out page operation, the page is in exclusive state, does not allow user Any element operation is carried out on this page.

L6, in local blank side, if the element lock for receiving the object element S0 of server transmission applies for successful message, Allow current action event to execute, and shows the operating result to object element S0 in local blank, it is in the present embodiment, i.e., aobvious Show the written handwriting of element S 0.

L7, in local blank side, in 0 writing process of element S, the operation thing that will also be shown in local blank The operating result that part generates is synchronized to distal end blank.

It can be write by one side, on one side synchronous mode, realize that the display content of multiple blanks in shared meeting is same Step.

L8 detects the action event B for element S 0 in distal end blank side.Such as move the action event of S0.

L9, distal end blank obtain the component identification of object element S0, and the lock application of element S 0 is sent to the server.

L10, server receive the lock application for element S 0 of distal end blank transmission, can inquire object element S0 Element lock already be allocated to local blank, therefore the element lock of element S 0 can not be distributed into distal end blank again, will not be to The element lock that distal end blank sends element S 0 applies for successful message.

In other embodiments, when server inquire object element element lock it is assigned, can also be to application Blank sends the element lock application failure news of object element, to prompt the current element of blank end subscriber inoperable.

L11, distal end blank is locked due to that can not obtain the element of element S 0, therefore shields current action event B.

The conflict for avoiding more people as a result, while same page elements being operated.

In the above-described embodiments, share meeting in blank to server send element lock application specific implementation include Following two situation: the event type of the action event is determined；If the event type for increasing element, then object element is first generated Component identification, then to server send element lock application；If modification element or the event type of deletion element, then obtain The component identification for taking object element sends element lock application to server.

Through the foregoing embodiment, no matter share what page elements other blanks user in meeting is operating, if certain blank User A wishes the newly-increased element in the blank page, he has this operating right always, not will lead to more people while the conflict write Problem.If user A, in writing elementary process, another blank user B thinks modification (the mobile or erasing) element at this time When, then it can not apply for the element lock (the element lock that user A has occupied the element) to the element, therefore user B cannot operate this Element.But if user A is in writing elementary process, another blank user B wants to write another element at this time, then uses Family B can apply for that the element to another element is locked, therefore user B can carry out the writing operation of another element.Due to being not necessarily to Just start to write at the end of user A writes, improves writing efficiency, be conducive to the effect of meeting for improving shared meeting.

In a specific example, referring to shown in Fig. 6 A, when the first blank and the second blank participate in shared meeting, first The user " Xiao Ming " of blank writes " hello " (element) on blank, therefore can obtain the element lock of " hello ", together When the second blank user " small red " at blank upper drawing circle (another element), therefore it can obtain round element lock.It is based on The exclusiveness of element lock, during " Xiao Ming " writing " hello ", " small red " of the second blank side can not be to element " hello " carries out any operation, and during " small red " picture circle, " Xiao Ming " of the first blank side can not also be carried out the circle Any operation.

During " Xiao Ming " " small red " written handwriting, while also carrying out the display content of the first blank and the second blank Synchronous, corresponding display effect is referring to shown in Fig. 6 B.

It is thus achieved that multiple users can write in blank simultaneously in the multiple blanks for participating in shared meeting Effect, and the written contents that will not influence each other；Due to just starting to write after terminating without waiting for other users writing, improve Efficiency is write, is conducive to improve shared effect of meeting.

Example 2: page operation event

M1 detects page operation event in local blank side (below by taking page P0 as an example).

M2 obtains the page iden-tity of page P0, and the lock application of page P0 is sent to the server.

Wherein, the page iden-tity of target pages P0 can be carried in page lock application；Page iden-tity can be the page number, The different pages have the different page numbers.

M3 receives the page for page P0 that local blank is sent and locks application in server-side.

M4, according to each in the page lock and target pages P0 of the page iden-tity query page P0 carried in page lock application Whether the element lock of element is assigned, if query result be it is no, the page of target pages P0 lock is distributed to and initiates application Local blank.

In some embodiments, the conference code of the shared meeting is also carried in the page lock application that blank is sent； Page lock application in this way can save the page lock distribution information of the corresponding page of the conference code with trigger the server.I.e. It, can also can be in server end when blank includes multiple pages, and multiple users respectively operate the different pages The page lock distribution information of the corresponding multiple pages of conference code is saved simultaneously.

M5, the page lock for sending target pages P0 to local blank apply for successful message.

M6, local blank side, the page lock for receiving the page P0 of server transmission apply for successful message, can be The page operation event to page P0 is executed on local blank, and shows page operation result.

M7, it is also that the operating result shown in local blank is same in page P0 operating process in local blank side It walks to distal end blank.

It can be operated by one side, on one side synchronous mode, realize that the display content of multiple blanks in shared meeting is same Step.

M8 detects the operation thing for element S 1 in action event C, such as modification page P0 in distal end blank side Part.

M9, distal end blank obtain the component identification of object element S1, and the lock application of element S 1 is sent to the server.

M10, server receive the lock application for element S 1 of distal end blank transmission, can inquire object element S1 The page lock of the page P0 at place already is allocated to local blank, therefore it is white the element of element S 1 lock can not to be distributed to distal end Plate, the element lock that element S 1 will not be sent to distal end blank apply for successful message.

In other embodiments, server can send the element lock application failure news of element S 1 to application blank, To prompt, the current element of blank end subscriber is inoperable or current page has been locked.

M11, distal end blank is locked due to that can not obtain the element of element S 1, therefore shields current action event C.

Through the foregoing embodiment, if no matter certain blank user A shares blank in meeting just in the whiteboard operating page at this time User B wishes what page elements operated, he avoids more people simultaneously to same one page always without this operating right as a result, The conflict that face is operated.

It is shown in Figure 8 in a specific example, when the first blank and the second blank participate in shared meeting, first The user " Xiao Ming " of blank carries out page movement operation, can obtain the page lock of current page；Based on the exclusive of page lock Property, during " Xiao Ming " carries out page movement operation, the user " small red " of the second blank side is if be also desired with page Face is mobile, it is desirable alternatively to be write on the page, it is desirable alternatively to modify the existing element in the page, however these operations are all It is not allowed to.That is, after the first blank side user obtains the page lock of the page, the second blank side user Do not allow to carry out any page operation or element operation for the page.

During " Xiao Ming " mobile page, while the display content synchronization of the first blank and the second blank is also carried out, Such as " Xiao Ming " is moved to the left the 30% of page horizontal length, accordingly, the page at the second blank end, which will also synchronize, to be moved to the left The 30% of horizontal length, realization are the synchronizations that blank shows content, and corresponding display effect is shown in Figure 8.

In one embodiment, as shown in figure 9, being said so that the method that blank content is shown is applied to server as an example It is bright, wherein the executing subject of each step can be understood as server, or the respective processor being interpreted as in server；The service Device is also possible to serve as the blank equipment of role server either dedicated server；In the shared meeting of the present embodiment Blank operation method the step of include:

S410 receives the element that the first blank is sent and locks application.

To share blank action event occurs for the application of element lock on the first blank in meeting, and the mesh of the action event It is designated as issuing in the case where page elements；The component identification of object element is carried in the element lock application；The target element Element is the page elements that the action event is directed to；

In embodiment, the first blank and the second blank belong to the same shared meeting, and the first blank and the second blank The page of display is identical.

S420 is being operated according to the action event whether component identification inquiry object element belongs to the second blank Page elements；If being not belonging to, the element lock of the object element is distributed into the first blank.

In one embodiment, the implementation of step S420 include: inquire object element where the page the page lock and Whether the element lock of object element is assigned to the second blank；If be it is no, the element of object element lock is distributed to the One blank.

Wherein, the element lock of element can be understood as weighing the EXCEPT operation of the element, in the embodiment of the present invention, with for the moment Between put the element locks of each page elements and be only capable of a blank user being assigned in shared meeting, such as: participate in it is identical Element 1 and element 2 are shown on the first blank and the first blank of shared meeting, if current first blank user applies obtaining The element of element 1 is locked, then the element lock based on element 1, and the second blank user will be unable to carry out any behaviour to the element 1 at this time Make；If the element lock of element 2 is unassigned at this time, the second blank user has an opportunity to obtain the element lock of element 2, obtain at In the case where function, then the second blank user can operate element 2, at this time the first blank user then can not to element 2 into Any operation of row；It is thus achieved that the first blank and the corresponding multiple users of the second blank can be simultaneously to different page elements The effect operated.

Page lock and element locking phase ratio, granularity is bigger, and specific difference includes: as any one blank user in shared meeting When application obtains the element lock an of element, other blanks user can also be to the other elements except the element in the blank page It is operated；However, other blanks user will when any one blank user obtains the page lock an of page in shared meeting Do not allow to carry out any operation for the page and the operation for element in the page.That is, the page lock of the page is divided With under state, an only user can be operated the page in shared meeting, do not supported more people while being carried out blank behaviour Make.
