Based on the hardware structure, the embodiment of the electronic whiteboard sharing method is provided.
Referring to fig. 4, fig. 4 is a schematic flowchart of a first embodiment of an electronic whiteboard sharing method according to the present invention, applied to a terminal device, where the method includes the following steps:
step S11: and collecting a coordinate point of the sliding operation on the first electronic whiteboard.
It should be noted that the first electronic whiteboard may be the electronic whiteboard software installed on the terminal device of the present invention, or may be other software integrated with the electronic whiteboard function installed on the terminal device, and of course, may also be an electronic whiteboard of other forms.
It should be appreciated that when the first electronic whiteboard is in the active state, the user can slide (e.g., draw lines, write words, etc.) on the first electronic whiteboard, and the terminal can detect the sliding operation. The sliding operation may be a sliding operation triggered by a user through at least one of a finger, a stylus, a mouse, a keyboard, and the like.
When the terminal monitors the sliding operation, in order to share the sliding operation with the second electronic whiteboard, a coordinate point of the sliding operation is collected. Note that the second electronic whiteboard is an electronic whiteboard that needs to share the sliding operation on the first electronic whiteboard.
Step S12: and judging whether the number of the currently collected coordinate points reaches N.
In the process of collecting the coordinate points of the sliding operation of the first electronic whiteboard, the terminal device may determine whether the number of currently collected coordinate points reaches N, where N is an integer greater than 1, for example, N may be 10, 20, 30, and the like, and if N is 10, determine whether the format of the currently collected coordinate points reaches 10.
It should be understood that, before step S12, the electronic whiteboard sharing method further includes: and determining the value of N. Wherein, the step of determining the value of N may include: the method includes the steps that a prestored value of N is directly obtained from terminal equipment, wherein N can be determined by terminal developers according to actual experience and is prestored in the terminal equipment, and therefore the prestored value of N can be directly obtained, and whether the number of currently collected coordinate points reaches N or not is judged. For example, suppose that a terminal developer determines N to be 20 according to practical experience, stores 20 in the terminal device in advance, acquires the pre-stored 20 from the terminal, and determines whether the number of currently acquired coordinate points reaches 20.
Or, the step of determining the value of N may further include: and determining the value of N according to a preset condition. The preset condition may be at least one of the currently occupied operating memory and the total operating memory of the terminal device, the number of the second electronic whiteboards, the speed of the sliding operation, and the like.
It should be understood that the number of the second electronic whiteboards affects the data processing amount of the server and the occupation amount of the network resources, and the larger the number of the second electronic whiteboards is, the larger the data processing amount of the server and the occupation amount of the network resources are, so in order to reduce the data processing amount of the server and the occupation amount of the network resources, the value of N may be determined according to the number of the second electronic whiteboards, wherein the larger the number of the second electronic whiteboards is, the larger the value of N is. Therefore, when the number of the second electronic whiteboards is large, the value of N is relatively large, and the times of forwarding the coordinate points by the server are relatively small under the condition that the total number of the coordinate points in the sliding operation is the same, so that the data processing amount and the network resource occupation amount of the server are reduced, and the probability of server and network breakdown is reduced; when the number of the second electronic whiteboards is small, the data processing amount of the server is small, so that the value of N can be relatively small, and the sharing real-time performance is guaranteed. The corresponding relationship between the number of the second electronic whiteboards and the value of N may be set by a terminal developer according to actual experience and stored in the terminal device in advance. For example, as shown in table 1 below, which is an example of a corresponding relationship between the number of the second electronic whiteboards and the value of N, assuming that the number of the second electronic whiteboards is 7 currently, it can be known from table 1 that the value of N is 15. Here, the correspondence relationship between the number of second electronic whiteboards and the value of N is described as an example in the form of a table, but the correspondence relationship between the number of second electronic whiteboards and the value of N is not limited to the form of a table, and may be presented in the form of a formula (for example, the value of N is a coefficient x the number of second electronic whiteboards) or the like.
TABLE 1
| Number of second electronic whiteboards | Value of N |
| 0-5 | 10 |
| 6-10 | 15 |
| …… | …… |
The operation memory of the terminal device affects the processing speed of the terminal device and the probability of occurrence of crash, so that, in order to ensure the processing speed of the terminal device and reduce the probability of occurrence of crash, the value of N can be determined according to the currently occupied operation memory and the total operation memory of the terminal device, wherein the larger the ratio of the occupied operation memory to the total operation memory is, the higher the value of N is, for example, the value can be set as: when the ratio of the occupied operation memory to the total operation memory is 0-20%, the value of N is 5; when the ratio of the occupied operation memory to the total operation memory is 20-50%, the value of N is 12; and when the ratio of the occupied operating memory to the total operating memory is 50-100%, the value of N is 20. Therefore, when the ratio of the occupied operation memory to the total operation memory is larger, the value of N is relatively higher, and the times of forwarding the coordinate points by the terminal equipment are relatively less under the condition that the number of the total coordinate points of the sliding operation is the same, so that the data processing amount and the network resource occupation amount of the terminal equipment are reduced, and the probability of collapse of the terminal equipment and a network is reduced; when the ratio of the occupied operation memory to the total operation memory is smaller, the processing speed of the terminal equipment is higher, and the probability of collapse is smaller, so that the value of N can be relatively smaller, and the sharing real-time performance is improved while the processing speed of the terminal equipment is ensured. The corresponding relationship between the occupied running memory and the total running memory, and the value of N can be set by a terminal developer according to actual experience and stored in the terminal device in advance. It should be noted that the corresponding relationship between the occupied operating memory and the total operating memory, and the value of N may be presented in the form of a table, a formula, and the like.
The speed of the sliding operation influences the time for collecting the N coordinate points, if the speed of the sliding operation is low, the longer the time for collecting the N coordinate points is, the sharing real-time performance is reduced, and the value size of the N influences the data processing amount of the terminal device, the server and the network, so that the value of the N can be determined according to the speed of the sliding operation, the corresponding relation between the speed of the sliding operation and the value of the N can be set by a terminal developer according to actual experience and stored in the terminal device in advance, and the faster the speed of the sliding operation is, the larger the value of the N is; or, the slower the speed of the sliding operation is, the larger the value of N is; of course, the corresponding relationship between the speed of the sliding operation and the value of N may be other relationships.
It should be noted that the three manners of determining the value of N according to the number of the second electronic whiteboards, or the currently occupied running memory and the total running memory of the terminal device, or the speed of the sliding operation may also be combined. For example, the value of N may be determined based on two references, i.e., the number of electronic whiteboards and the speed of the sliding operation.
Step S13: and if so, forwarding the N coordinate points to the second electronic whiteboard through the server.
When the number of the currently acquired coordinate points reaches N, the N coordinate points are forwarded to the second electronic whiteboard through the server, that is, when the N coordinate points are acquired, the N coordinate points are sent to the server together, and after the server receives the N coordinate points, the server forwards the N coordinate points to the second electronic whiteboard so as to synchronize the second electronic whiteboard after receiving the N coordinate points according to the N coordinate points. The method has the advantages that N (N is an integer larger than 1) coordinate points are collected and sent once, and compared with the mode that the coordinate points are sent once every time one coordinate point is collected, the frequency of sending the coordinate points to a server by the terminal device is reduced, so that the data processing amount of the terminal device is reduced, the network resource occupation amount is reduced, the collapse probability is reduced, and meanwhile, the frequency of sending the coordinate points to the server by the terminal device is reduced, so the processing pressure of the server is also reduced; compared with a mode of sending the collected coordinate points once at intervals, the method takes the number of the coordinate points into consideration during sending, so that the backlog of the coordinate points is less even if the sliding speed is high, and the sharing real-time performance is ensured.
Optionally, after step S11, the electronic whiteboard sharing method further includes: storing the collected coordinate points into a container; thus, step S12 includes: and judging whether the number of the coordinate points in the container reaches N. Step S13 includes: and if so, forwarding the N coordinate points in the container to the second electronic whiteboard through the server. That is, in this embodiment, a container may be provided in advance for storing the collected coordinate points of the sliding operation. It should be noted that after the coordinate points in the container are forwarded to the second electronic whiteboard through the server, the coordinate points in the container may be cleared to store the coordinate points which are not forwarded to the second electronic whiteboard, that is, when a coordinate point is collected, the coordinate point is stored in the container, when the number of the coordinate points in the container reaches N, the N coordinate points in the container are forwarded to the second electronic whiteboard through the server, and the container is cleared, after a coordinate point is collected again, the coordinate point is stored in the container, and when the number of the coordinate points in the container reaches N again, the N coordinate points in the container are forwarded to the second electronic whiteboard through the server, and the container is cleared, and then, the process is repeated, so that the coordinate points which are stored in the container are always forwarded to the second electronic whiteboard through the server.
In this embodiment, the starting coordinate point of the sliding operation may be one of the N coordinate points, and is forwarded to the second electronic whiteboard through the server together with the other N-1 coordinate points. Alternatively, it may be forwarded to the second electronic whiteboard separately through the server, in which case, after step S11, the method further includes: when the collected coordinate point is the initial coordinate point of the sliding operation, the initial coordinate point is forwarded to the second electronic whiteboard through the server, and in the mode, the initial coordinate point is not used as one of the N coordinate points, so that the initial coordinate point is not required to be stored in the container.
In this embodiment, after step S11, referring to fig. 5, the electronic whiteboard sharing method further includes:
and step S21, when the ending coordinate point of the sliding operation is collected, judging whether a coordinate point to be forwarded to the second electronic whiteboard exists or not except the ending coordinate point.
In this embodiment, when the sliding operation is finished, the end coordinate point is collected. And judging whether the sliding operation is finished or not according to different modes of triggering the sliding operation. For example, assuming that the terminal device is a computer, the first electronic whiteboard is electronic whiteboard software installed on the computer, and the user presses and drags the mouse to trigger a sliding operation for the first electronic whiteboard, when the user releases the mouse (and the mouse pops up), it is determined that the sliding operation is finished; or, assuming that the terminal device is a tablet computer, the first electronic whiteboard is electronic whiteboard software installed on the tablet computer, and the user slides and triggers a sliding operation for the first electronic whiteboard through a display screen of the tablet computer, when the user's finger leaves, it is determined that the sliding operation is finished.
In this embodiment, when acquiring N coordinate points, the N coordinate points are forwarded to the second electronic whiteboard through the server, and when acquiring an end coordinate point, a certain number of coordinate points may exist. Therefore, when the end coordinate point is collected, it is first determined whether there is a coordinate point to be forwarded to the second electronic whiteboard, if so, go to step S22, and if not, go to step S23. In one example, since the collected coordinate points that are not forwarded to the second electronic whiteboard through the server are stored in the container, determining whether there are coordinate points to be forwarded to the second electronic whiteboard other than the end coordinate point includes: it is determined whether or not the coordinate point is stored in the container, and if the coordinate point is stored in the container, the process proceeds to step S22, and if the coordinate point is not stored in the container, the process proceeds to step S23.
And S22, forwarding the coordinate point to be forwarded to the second electronic whiteboard and the ending coordinate point to the second electronic whiteboard through the server.
And the coordinate point to be forwarded to the second electronic whiteboard exists besides the ending coordinate point, so that the coordinate point to be forwarded to the second electronic whiteboard and the ending coordinate point are forwarded to the second electronic whiteboard through the server. In one example, since the coordinate points to be forwarded to the second electronic whiteboard are stored in the container, the coordinate points in the container and the end coordinate points are forwarded to the second electronic whiteboard through the server.
The coordinate point to be forwarded to the second electronic whiteboard and the ending coordinate point can be sent to the server together and forwarded to the second electronic whiteboard through the server, or the coordinate point to be forwarded to the second electronic whiteboard can be forwarded to the second electronic whiteboard through the server, and the ending coordinate point is forwarded to the second electronic whiteboard through the server.
And S23, forwarding the ending coordinate point to the second electronic whiteboard through the server.
And the coordinate point which is not forwarded to the second electronic whiteboard does not exist except the ending coordinate point, so that the ending coordinate point is directly forwarded to the second electronic whiteboard through the server. For better understanding, this is illustrated here with an example: assuming that N is 10, when the number of the coordinate points in the container is 5, the end coordinate point is detected, and the coordinate points are stored in the container, so that the 5 coordinate points in the container and the end coordinate point are together forwarded to the second electronic whiteboard through the server, or the 5 coordinate points in the container are first forwarded to the second electronic whiteboard through the server, and then the end coordinate point is forwarded to the second electronic whiteboard through the server.
Referring to fig. 6, fig. 6 is a schematic flowchart of a second embodiment of the electronic whiteboard sharing method according to the present invention, applied to a server, where the method includes the following steps:
step S31: and receiving the N coordinate points sent by the terminal equipment when the number of the collected coordinate points reaches N.
The coordinate points received by the server are coordinate points corresponding to sliding operation on the first electronic whiteboard of the terminal equipment, and N is an integer greater than 1. That is to say, the terminal device collects coordinate points of the sliding operation on the first electronic whiteboard, and when the number of the collected coordinate points reaches N, the N coordinate points are sent to the black server together, and the server receives the N coordinate points.
Step S32: and sending the N coordinate points to a second electronic whiteboard.
Optionally, before step S31, the method further includes: receiving an initial coordinate point of sliding operation sent by a terminal device; and sending the starting coordinate point to the second electronic whiteboard. That is to say, the terminal device sends the start coordinate point to the server independently as soon as the start coordinate point is collected, and the server sends the start coordinate point to the second electronic whiteboard after receiving the start coordinate point, so that the second electronic whiteboard synchronizes according to the received coordinate point.
Optionally, the method further includes: receiving an end coordinate point of the sliding operation, which is sent by the terminal equipment; and sending the ending coordinate point to the second electronic whiteboard.
The above embodiments have explained the method of the terminal device side, and the present embodiment is a method of the server side, which has similar examples and is not described herein again.
