Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the drawings described above, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Before formally describing the embodiments of the present application, a scenario in which the present application is applied and a technical problem existing in the scenario are described with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of an interactive tablet applied in the present application, where a scene in which a user needs to share a presentation in an electronic device 1 in a meeting is taken as an example, and due to a limitation of a screen size of the electronic device 1, after the user can connect the electronic device 1 with a data transmission device 3 by using a connection line 2, a picture of the presentation displayed in a page of the electronic device 1 is transmitted to an interactive tablet 4 hung on a wall through the data transmission device 3 to be displayed.
The electronic device 1 may also be a device with a display interface, such as a notebook computer, a tablet computer, a desktop computer, or a workstation; the data transmission device 3 may also be called a screen projecting device, a wireless screen projecting device, a screen transmitting device, or a wireless screen transmitting device, and the interactive tablet 4 may also be called an interactive smart tablet, a smart interactive whiteboard, a large-screen tablet, or the like. The data transmission device 3 and the interaction tablet 4 may be connected through wireless communication, including but not limited to: wireless Fidelity (Wi-Fi), bluetooth or other short-distance Wireless communication modes, etc. The interactive tablet 4 can cooperate with the data transmission device 3 to realize sharing of the presentation in the electronic device 1. In some embodiments, the interactive tablet 4 is also capable of enabling remote instant messaging alone and providing writing canvas functionality through a touchable panel. In some implementations, the data transmission device 3 and the interactive tablet 4 may be provided by the same manufacturer, and the user may purchase the data transmission device 3 and the interactive tablet 4 at the same time, and after installing the interactive tablet 4 on the wall of the conference room, transmit the page of the electronic device 1 to the interactive tablet 4 for display by using the data transmission device 3.
The electronic device 1 and the data transmission device 3 are capable of data communication, for example, a connection line 2 may be provided between the electronic device 1 and the data transmission device 3 to connect to each other by wired communication. The connection line 2 may be a Universal Serial Bus (USB) connection line, a High Definition Multimedia Interface (HDMI) connection line, or a network line. In one embodiment, the USB connection may be a USB Type-C connection.
In some embodiments, the connection line 2 may be provided separately from the data transmission device 3, and the connection line 2 may be provided by a manufacturer of the data transmission device 3 or purchased separately by a user. In other embodiments, the connection line 2 and the data transmission device 3 may be integrally disposed, that is, the connection line 2 and the data transmission device 3 form an integral device, and at this time, the connection line 2 may be regarded as a part of the data transmission device 3, so that when a user connects the data transmission device 3 to the electronic device 1, a step of connecting the data transmission device 3 to one end of the connection line 2 may be omitted, and only the electronic device 1 needs to be connected to the other end of the connection line, thereby improving efficiency, and avoiding a situation that the data transmission device 3 cannot be connected to the electronic device 1 because the connection line 2 cannot be found.
Fig. 2 is a schematic diagram of a scenario in which the present application is applied, as shown in fig. 2, in some practical applications, different interactive flat panels 4 may also communicate with each other, so that two or more than two interactive flat panels 4 may jointly display the same page. For example, after the user a uses the data transmission device to transmit the page of the electronic device to the interaction panel 41 for display, the interaction panel 41 may transmit the displayed page to the interaction panel 42 and the interaction panel 43 at the same time, and at this time, the pages displayed by three interaction panels 41-43 in total are the same. In the embodiment of the application, the specific communication mode for transmitting the page between the interactive flat panels is not limited, and the interactive flat panels can communicate with each other through a wired connecting line or communicate with each other through wireless communication modes such as Wi-Fi and bluetooth.
Meanwhile, each interactive tablet may provide a function of the user operating the displayed page, for example, the user a may operate the page of the interactive tablet 41, the user B may operate the page of the interactive tablet 42, and the user C may operate the page of the interactive tablet 43. In the prior art, in order to prevent mutual conflicts between operations performed by different users on the same page, when one user operates a page of the interaction tablet, the other interaction tablets displaying the same page do not allow the user to perform any operation, for example, when any user a operates a page on the interaction tablet 41, the interaction tablet 41 may send information to the interaction tablet 42 and the interaction tablet 43 to instruct the interaction tablet 42 and the interaction tablet 43 to lock the displayed page by means of "page lock" or the like, and at this time, the user B and the user C cannot operate the page. Subsequently, when the user a finishes operating on the page displayed by the interaction tablet 41, the interaction tablet 41 sends information to the interaction tablet 42 and the interaction tablet 43 again, instructing the interaction tablet 42 and the interaction tablet 43 to close the "page lock".
However, in the prior art, when a plurality of interactive flat panels display the same page, a plurality of users are not allowed to simultaneously operate the same page through the plurality of interactive flat panels, and only the interactive flat panels simply prevent operation conflicts by locking the displayed page, so that the interactive flat panels cannot support the simultaneous operation of the plurality of users on the plurality of interactive flat panels, and the interactive flat panels cannot be applied to more use scenes, thereby causing the function of the interactive flat panels to be single, and seriously reducing the use experience of the interactive flat panel users.
Therefore, the application provides an interactive tablet and a control method of the interactive tablet, so that when a plurality of interactive tablets display the same page, different users are allowed to operate the page on the plurality of interactive tablets at the same time, and a solution for conflicts among operations performed by different users is further provided. The technical solution of the present application will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 3 is a schematic diagram of an application scenario of the control method for the interactive tablet, where an example is that any interactive tablet in the scenario shown in fig. 2 is a first interactive tablet, and any other interactive tablet is a second interactive tablet, and the control method for the interactive tablet provided by the present application is explained. As shown in fig. 3, the first interactive flat plate and the second interactive flat plate display the same page, and mark the page as a target page, and take as an example that the target page at least includes a circle, a rectangle, and a triangle, mark a circle icon in the target page as a first element (i), and mark a rectangle icon in the target page as a second element (ii), so that the first interactive flat plate and the second interactive flat plate allow the user a and the user B to simultaneously operate the target pages respectively displayed by the two interactive flat plates on the basis of simultaneously displaying the target page.
In order to unify operations performed on the same target page on different interactive flat plates, after acquiring an operation performed on a certain element on the target page displayed by the user, each interactive flat plate transmits the operation performed on the element by the user to other interactive flat plates, so that the other interactive flat plates perform the same operation on the element operated by the user.
Optionally, the operation on the element provided in the embodiments of the present application includes: adding operation, deleting operation, editing operation, erasing operation and the like to the elements in the target page. The newly added elements comprise: inserting handwriting, circles, pictures, tables, pages, and the like; the delete element includes: deleting circles, tables, figures, handwriting, etc.; the editing elements include: modifying pages (background, zoom, roam, etc.), modifying elements (move, zoom, rotate, line thickness, color, table add rows and columns, etc.); the erasure element includes: the handwriting, the graph and the like can be erased, and one handwriting can be erased into a plurality of sections or can be erased completely.
For example, in fig. 3, assuming that the user a performs a moving operation on a first circular element (r) on a target page displayed by a first interactive tablet, for the first interactive tablet, after it is detected that the user a performs the moving operation on the first element (r), the identification information (r) of the first element (r), the coordinates (X1, Y1) of the first element (r) before moving in the target page, and the coordinates (X2, Y2) after moving are sent to a second interactive tablet in an instruction manner, so that the second interactive tablet performs the same moving operation on the first element (r) on the displayed target page according to the received instruction, thereby keeping the same with the operation performed on the first interactive tablet, and further achieving the transfer synchronization of element operations between different interactive tablets.
Optionally, the above example takes the movement of an element as an example, and the instructions transferred between the interactive tablets may further include one or more of the following: ID, coordinates, color, line thickness, shape, and boundary position of the element. As an interactive tablet detecting that an element in a target page is operated by a user, after serialized packaging is performed on the element, the operation and other related data, the element, the operation and other related data are sent to all other interactive tablets displaying the same target page in an instruction manner, so that the elements in the target page displayed by all the interactive tablets displaying the same target page are kept consistent.
In particular, in the embodiment of the present application, since different interaction panels are allowed to operate elements on one target page at the same time, a certain time sequence relationship exists, and in a specific implementation manner, as shown in fig. 3, it is assumed that a user a operates a first element (i) on the target page displayed by a first interaction panel to perform a first operation, and a user B operates a second element (ii) on the target page displayed by a second interaction panel to perform a second operation. At this time, if the first interactive tablet receives a command indicating the second element (ii) to perform the second operation sent by the second interactive tablet in the process of obtaining the first operation performed by the user on the first element (i), the first interactive tablet may directly perform the same second operation on the second element (ii) on the page.
Fig. 4 is a flowchart illustrating an embodiment of a control method for an interactive tablet provided in the present application, where the method shown in fig. 4 may be applied to the scenario shown in fig. 3, where the control method includes:
s101: the first interactive flat panel acquires a first operation executed corresponding to the first element.
Specifically, referring to fig. 3, in S101, the first interactive tablet detects and receives a first operation performed by the user a on a first element (i) in a target page displayed by the first interactive tablet, where the first operation may be a moving operation, for example, the user a moves the first element (i) to the upper left corner of the target page. In this embodiment, the specific operation mode of the user of the interactive tablet on the element is not limited, and the element may be operated through an interactive device such as a mouse, a keyboard, a touchable screen, and the like, in S101, the first interactive tablet detects and acquires the first operation performed on the first element by the user through the interactive device.
S201: the first interactive flat plate receives a first instruction sent by the second interactive flat plate.
Referring to fig. 3, before S201, the first interactive tablet and the second interactive tablet display the same target page, and the user B performs a second operation on the second element on the second interactive tablet, and if the second operation is a delete operation, the second interactive tablet generates, for example, a first instruction including an ID of the second element and the delete operation after acquiring the second operation on the second element on the target page, and sends the first instruction to the first interactive tablet. In S201, after receiving the first instruction sent from the second interactive tablet, the first interactive tablet may determine, according to an instruction of the first instruction, a second operation corresponding to a second element on the target page.
S202, the first interactive flat panel executes a second operation on a second element on the displayed target page according to the first instruction.
Specifically, the first interactive tablet performs the same second operation on the second element on the target page according to the instruction of the first instruction received in S201. Referring to fig. 4 and 5, fig. 5 is a schematic diagram of a display state of a target page provided in the present application, and it is noted that in S101, the first interactive tablet starts a first operation of acquiring a first element on the target page at time t0, and then in fig. 5, the target page displayed by the first interactive tablet before time t0 is the same as the initial state shown in fig. 3. And at time t0, when the first interactive tablet receives the first instruction, the first interactive tablet performs a delete operation on the second element (ii) in the target page according to the first instruction at time t1, and in fig. 5, the target page displayed by the first interactive tablet after time t1 deletes the second element (ii).
It is understood that during the execution of S202, the first interactive tablet is still in the detection state, and assuming that the first operation of the first element determined by the first interactive tablet starts at time t0 and ends at time t2, between time t0 and time t2, the first interactive tablet may execute the receiving first instruction in S201 and execute the second operation on the second element according to the first instruction in S202 while executing S101 to obtain the first operation corresponding to the first element.
After time t1, the display state of the first interactive tablet is as shown in fig. 5, and the displayed target page has the second element (c) deleted according to the first instruction, and at the same time, the element of the first element (r) is detected and still in a state of determining the moving operation of the first element (r). For the user a of the first interactive flat plate, the intuitive feeling is that while the first interactive flat plate operates the first element (i) on the target page, the second element (ii) on the target page disappears, that is, the first interactive flat plate performs the deletion operation of the second element (ii) by the users of other interactive flat plates.
S102, the first interactive flat plate determines that the first element finishes executing the first operation.
Specifically, after the time t2, the first interaction tablet determines that the user has finished moving the first element, referring to fig. 6, where fig. 6 is a schematic diagram of a display state of the target page provided by the present application, and at the time t2 corresponding to S102, the first interaction tablet determines that the first element (i) has finished moving, and has moved to the upper left corner of the target page, and at this time, the first element (i) of the second interaction tablet is still in a state before moving.
S103, the first interactive flat plate sends a second instruction to the second interactive flat plate.
Subsequently, in S103, the first interactive tablet sends a second instruction to the second interactive tablet, where the second instruction is used to indicate a move operation of the first element (r), and the second instruction may include information such as an ID and moved coordinates of the first element (r).
And S104, executing a first operation on a first element (i) in the displayed target page by the second interactive flat plate according to the second instruction.
Referring to fig. 7, fig. 7 is a schematic diagram of a display state of the target page provided by the present application, as shown in fig. 7, after the second interactive tablet receives the second instruction, at time t3 corresponding to S104, the same moving operation is performed on the first element (i) in the display page, so that the target page displayed by the second interactive tablet is consistent with the first interactive tablet at time t3 and later.
In summary, in this embodiment, for the first interactive tablet, while obtaining the first operation that the user a correspondingly executes on the first element on the target page, the first interactive tablet may also receive the first instruction of the second interactive tablet, and execute the second operation on the second element on the target page according to the first instruction, so that when multiple interactive tablets display the same target page at the same time, different users may simultaneously operate the elements on the interactive tablets, and the operations performed on the elements between the interactive tablets may be synchronized. The interactive tablet can be applied to a use scene that multiple people operate the same target page at the same time, and functions provided by the interactive tablet are greatly enriched, so that the use experience of interactive tablet users is improved.
It should be noted that, in this embodiment, the interaction between the first interaction tablet and the second interaction tablet is taken as an exemplary description, and in an actual implementation, when a plurality of interaction tablets simultaneously display a target page, any interaction tablet that acquires an operation corresponding to an element in the target page sends the same instruction to all other interaction tablets, so that the elements on the target page displayed by all the plurality of interaction tablets are kept consistent. In addition, in this embodiment, taking the movement of the first element (i) and the deletion of the second element (ii) as an example, the specific implementation manner and principle of other operations performed on the elements are the same and are within the protection scope of the embodiment of the present application, and are not described again.
In the embodiments provided in fig. 3 to fig. 7, for different elements when the user a operates on the same target page on the first interactive tablet and the user B operates on the second interactive tablet, the interaction tablets synchronize the elements on the target page. In another scenario, the user a and the user B may operate the same element on the same target page on the first interactive tablet and the second interactive tablet, respectively, and there is a possibility of conflict. For example, fig. 8 is a schematic diagram of another application scenario of the control method for an interactive tablet provided by the present application, where a user a performs a moving operation on a first element (i) on a target page displayed by a first interactive tablet, and a user B performs a deleting operation on the first element (i) on the target page displayed by a second interactive tablet at the same time, at this time, two users have a conflict between operations on the same element on the same target page, so that the control methods for three possible interactive tablets provided by the present application solve the conflict that may exist in the scenario illustrated in fig. 8, and are described below separately.
A first control method. Fig. 9 is a flowchart illustrating an embodiment of a control method for an interactive tablet provided in the present application, where the method shown in fig. 9 may be applied to the scenario shown in fig. 8, where the control method includes:
s301, the first interactive flat plate acquires a first operation executed corresponding to the first element.
Specifically, the first interactive tablet detects and receives a first operation performed by the user a on the first element (r) in the target page displayed by the first interactive tablet, where the first operation may be a moving operation, for example, the user a moves the first element (r) to the upper left corner of the target page. In this embodiment, the specific operation mode of the user of the interactive tablet on the element is not limited, and the element may be operated through an interactive device such as a mouse, a keyboard, a touchable screen, and the like, and in S301, the first interactive tablet detects and acquires the first operation performed on the first element by the user through the interactive device.
S401: and the first interactive flat plate receives a third instruction sent by the second interactive flat plate.
Referring to fig. 10, fig. 10 is a schematic diagram of a display state of a target page provided by the present application, before a start time t4 corresponding to S301, a user B has performed a third operation on a first element (r) on a second interactive tablet, and assuming that the third operation is a delete operation, after obtaining the third operation on the first element (r) on the target page, the second interactive tablet generates a third instruction including, for example, an ID of the first element and the delete operation, and sends the third instruction to the first interactive tablet. Then in S401 the first interactive tablet receives a third instruction sent from the second interactive tablet.
S302: the first interactive tablet stops the first operation performed by the first element in S301 and then performs a third operation on the first element in S303 according to the third instruction received in S401.
Referring to fig. 11, fig. 11 is a schematic diagram of a display state of a target page provided by the present application, after a time t4 shown in fig. 10, if the first interaction tablet receives a third instruction, a deletion operation corresponding to the first element (r) can be determined according to the third instruction, at this time, the first interaction tablet no longer continues to detect a moving operation of the first element (r) by the user a, and directly executes the deletion operation on the first element (r) on the target page.
That is, in the first control method, when a plurality of users operate the same element through different interactive tablets at the same time, the operation result of the operation completed first is used as a standard. At this time, for the user of the first interactive tablet, it is intuitive that the first element (r) is seen to disappear when the first interactive tablet is being moved, that is, the first interactive tablet performs the deletion operation of the first element (r) by the users of other interactive tablets. Finally, after time t5 shown in FIG. 11, the first interactive tablet deletes the first element (r) to maintain consistency with the target page displayed by the second interactive tablet.
Second, a second control method. Fig. 12 is a flowchart illustrating an embodiment of a control method for an interactive tablet provided in the present application, and the method shown in fig. 12 may also be applied to the scenario shown in fig. 8, where S301 and S401 of the control method are the same as the embodiment shown in fig. 9, and are not repeated.
The difference is that after the third instruction is received in S401, the first interactive tablet does not stop obtaining the first operation correspondingly executed by the first element, but does not execute the third instruction. At the time t6 corresponding to S302a, the first interactive tablet determines that the first element (r) completes the move operation and moves to the upper left corner of the target page, and at this time, referring to fig. 13, fig. 13 is a schematic diagram of a display state of the target page provided by the present application, the first element (r) on the second interactive tablet has been executed with the delete operation before the time t6, and the second interactive tablet sends a third instruction to the first interactive tablet. Since the first interactive tablet does not execute the third instruction, but completes the operation of S301 to acquire the first element (i) to move to the upper left corner, then, in S303a, the first interactive tablet sends the second instruction to the second interactive tablet. Which is used to indicate the move operation of the first element (r).
Finally, in S304a, the second interactive tablet performs the same move operation as the first interactive tablet on the first element (r) in the target page displayed by the second interactive tablet according to the second instruction. Referring to fig. 14, fig. 14 is a schematic diagram of a display state of a target page provided in the present application, after receiving a second instruction, the second interactive tablet performs the same moving operation on the first element (r) in the display page at time t7 corresponding to S304 a.
That is, in the second control method, when a plurality of users operate the same element through different interactive tablets at the same time, the operation result of the last completed operation is used as the standard. At this point, no change is felt by the user of the first interactive tablet. For other users who interact with the tablet, the intuitive feeling is that the first element (i) is seen to execute the deleting operation, and then the first element (i) is seen to appear and the moving operation is realized. Finally, after time t7 shown in FIG. 12, the second interactive tablet moves the first element (r) to remain consistent with the target page displayed by the first interactive tablet.
And thirdly, a third control method. Referring to fig. 8, when the first interaction tablet acquires the first operation that the user a correspondingly executes on the first element (r), the first interaction tablet may send the indication information to all other interaction tablets including the second interaction tablet at time t4, so that the other interaction tablets lock the first element (r) on the target page displayed by the other interaction tablets according to the indication information, at this time, for the user B on the second interaction tablet, the first element (r) cannot be operated on the target page, but the user B may still operate on other elements on the target page except the first element (r). Subsequently, after the user a completes the first interactive tablet determines that the user a completes the moving operation of the first element (r), a second instruction may be sent to the second interactive tablet to indicate the moving operation of the first element (r), and indication information may also be sent to the second interactive tablet, so that the second interactive tablet performs an operation of unlocking the first element (r) on the displayed target page.
Optionally, in the actual application process of the interactive tablet, the three control methods may be used in any way, or one of the three control methods may be specified by a person who provides the target page each time.
In addition, for example, fig. 15 is a schematic diagram of another application scenario of the control method for an interactive tablet provided by the present application, where while the user a operates the background on the target page displayed on the first interactive tablet, the user B also operates the background on the target page displayed on the second interactive tablet, and at this time, there is a conflict between the operations of the two users on the background on the same target page, so that the present application further provides a control method for solving the conflict that may exist in the scenario illustrated in fig. 15.
Fig. 16 is a schematic flowchart of an embodiment of a method for controlling an interactive tablet according to the present application, where the method shown in fig. 16 may be applied to the scenario shown in fig. 15, and in this embodiment, if the first element is a background of a target page, the method includes:
s301, the first interactive flat panel acquires a first operation executed corresponding to the background.
Specifically, the first interactive tablet detects and receives a first operation performed by the user a on a background in a target page displayed by the first interactive tablet. In this embodiment, the specific operation mode of the user of the interactive tablet for the element is not limited, and the element may be operated through an interactive device such as a mouse, a keyboard, a touchable screen, and the like, and in S301, the first interactive tablet detects and acquires the first operation performed by the user on the background through the interactive device.
S401: and the first interactive flat plate receives a third instruction sent by the second interactive flat plate.
Referring to fig. 17, fig. 17 is a schematic diagram of a display state of a target page provided in the present application, before a start time t8 corresponding to S301, a user B has performed a third operation on a background of the target page on a second interactive tablet, and adjusts the background into a grid shape as shown in fig. 8, and after obtaining the third operation on the background on the target page, the second interactive tablet generates a third instruction including, for example, an ID of the background and a shape of the background, and sends the third instruction to the first interactive tablet. Then in S401 the first interactive tablet receives a third instruction sent from the second interactive tablet.
In S402: and the first interactive flat plate executes a third operation on the background on the target page according to the third instruction.
Specifically, the first interactive tablet performs the same third operation on the background on the target page according to the instruction of the third instruction received in S401. Referring to fig. 18, fig. 18 is a schematic diagram of a display state of a target page provided by the present application, at time t9 corresponding to S402 shown in fig. 18, the first interactive tablet has performed a third operation on the background, so that the background of the first interactive tablet and the background of the second interactive tablet at time t9 are kept consistent. It is understood that during the execution of S401, S402, the first interactive tablet also executes the actor S301 at the same time.
S302b, the first interactive tablet determines that the first operation of the user on the background has been performed in S301, referring to fig. 19, fig. 19 is a schematic diagram of a display state of the target page provided by the present application, and at time t10 corresponding to S302b in fig. 19, the background of the target page displayed by the first interactive tablet is modified into a cross-diagonal shape according to the user a, and is different from the background of the second interactive tablet.
Subsequently, in S303b, the first interactive tablet sends a second instruction to the second interactive tablet for indicating a modification operation on the background. And enabling the second interactive flat plate to execute the same modification operation on the background in the target page displayed by the second interactive flat plate according to the second instruction. Referring to fig. 20, fig. 20 is a schematic diagram of a display state of the target page provided by the present application, and as shown in fig. 20, after the second interaction tablet receives the second instruction, at a time t11 corresponding to S304b, the same modification operation is performed on the background in the display page, so that the background of the target page displayed by the second interaction tablet is consistent with the background of the first interaction tablet at a time t11 and later. In the whole process, for a scene that a plurality of interactive flat panels modify the background of the displayed page at the same time, the interactive flat panels take the latest updated background as the standard.
In summary, with reference to fig. 8-20, in the control method of the interactive tablet provided in the present application, when the first interactive tablet acquires a first operation that is correspondingly executed by the user a on a first element on the target page, if a second instruction that is sent by the second interactive tablet and is also executed on the first element is received, several feasible control methods are proposed for the possible conflict, so that when multiple interactive tablets simultaneously display the same target page, different users can simultaneously operate the elements on the interactive tablets, and when different users operate the same elements, a solution is provided for the possible conflict. Therefore, the embodiment can further enrich the functions provided by the interactive tablet, and avoid possible conflicts when different users operate the pages on a plurality of interactive tablets simultaneously, thereby ensuring the reliability of the control method, increasing the stability of the interactive tablet during operation, and further improving the use experience of the interactive tablet users.
In the above embodiments, the addition, deletion, and editing of an element are mainly exemplarily described, and for the erasing operation of an element, a part of a straight line is erased as an example, after the straight line displayed by the interactive tablet is erased, the straight line is first deleted on the page, and then the two line segments remaining after being erased are displayed.
For example, fig. 21 is a schematic diagram of another application scenario of the interactive tablet control method provided in the present application, and as shown in fig. 21, it is assumed that at least a third interactive tablet, a second interactive tablet, and a first interactive tablet commonly display the same page. When the third interactive tablet receives an erasing operation of the user a on the page straight-line writing element L1 (referred to as a third element in the embodiment) at the time t20, the third interactive tablet deletes the element L1 at the time t21 first, and then redisplays the element L11 and the element L12 according to a superposition part of the erasing operation and the element L1 at the time t22, so that the erasing operation on the first part of the element L1 is realized, and a fourth instruction is sent to the first interactive tablet for indicating the operating operation on the first part of the third element. Similarly, if it is assumed that the second interactive tablet erases the second portion of the first element at the same time that the third interactive tablet erases the first portion of the first element, and after the second interactive tablet erases the second portion of the first element at time t32, the second interactive tablet sends a fifth instruction to the first interactive tablet for instructing the erasing operation of the second portion of the third element. At this time, for the first interactive tablet, an instruction for erasing the first part and the second part of the third element L1 is received at the time t40, and after the first interactive tablet deletes the L1 element at the time t41, the newly added element L11, element L12, element L21 and element L22 are displayed at the time t42, and because there are overlapping portions among the four elements, no erasing operation is performed on the third element L1 displayed on the first interactive tablet after the overlapping portions exist.
Therefore, the present embodiment provides a method for controlling an interactive tablet, which can avoid the problem of collision that may occur when the erasing operations performed on the same third element are synchronized as shown at time t42 in fig. 21, and implement all partial erasing. Referring to fig. 22, fig. 22 is a schematic diagram of another application scenario of the interactive tablet control method provided by the present application, as shown in fig. 22, after receiving the fourth instruction and the fifth instruction at time t40, the first interactive tablet serving as an execution main body of the present embodiment does not display immediately, but first calculates, according to the fourth instruction and the fifth instruction, a plurality of remaining portions L31, L32, and L33 obtained after the third element L1 is erased from the first portion and the second portion, then performs an operation of deleting the third element in t41, and finally displays the finally obtained remaining portions L31, L32, and L33 on the target page at time t42, so as to implement a simultaneous erasing operation of the first portion and the second portion of the first element L1.
It can be understood that the processing idea of the present application is that after an interactive tablet receives an instruction of an element erasing operation, the interactive tablet is combined with the erasing operation being performed or to be performed, and after a common erasing result is calculated, the remaining part of the obtained result is displayed, so that no conflict is generated when an element is erased at the same time, and all erasing operations can be implemented. At this time, for the third interactive tablet, after the time t22, when the fifth instruction of the second interactive tablet is received, the third interactive tablet combines the erasing operation of the first part that it has performed with the erasing operation of the second part indicated by the fifth instruction, and the remaining part can also be calculated and displayed, so that the page displayed by the third interactive tablet and the page displayed by the first interactive tablet at the time t42 are the same; for the second interactive tablet, after receiving the fourth instruction of the third interactive tablet after the time t32, the second interactive tablet may also calculate and display the remaining part by combining the erasing operation of the second part that it has performed with the erasing operation of the first part indicated by the fourth instruction, so that the page displayed by the second interactive tablet and the page displayed by the first interactive tablet at the time t42 are the same.
In addition, in the embodiments of the present application, in the overall scheme, all the content and operations of the interactive tablet that need to be synchronized are finely divided, and the content and the operations can be subdivided according to each operation of each element, and conflict processing schemes in various control methods are comprehensively used, instead of using only one processing scheme for data synchronization, so that it is ensured that users can simultaneously operate and avoid conflicts.
