Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
The technical scheme provided by the embodiment of the disclosure may only involve two parties: a presenter terminal and a participant terminal. The presenter terminal can synchronize the page information corresponding to the page of the document currently displayed by the presenter terminal and the position information of the ink mark on the page to the participant terminal, and after receiving the synchronization data, the participant terminal can synchronously display the content displayed on the presenter terminal on the screen of the participant terminal. Here, the technical solution provided by the embodiments of the present disclosure may further relate to a server, where the server may forward the data information sent by the presenter terminal to the participant terminal, and the data information sent by the participant terminal to the presenter terminal. In the process, a participant can use own participant terminal to watch the content demonstrated by the demonstrator, the content is not limited by the conference television, and the information transmitted to the participant terminal only has document content and some state information, so that the synchronization of the conference content can be completed by using less flow, the resource occupation is less, and the conference terminal can be used under the condition of power failure.
Fig. 1 is a schematic diagram of a conference presentation method according to an exemplary embodiment, as shown in fig. 1, which is used in a presenter terminal, and includes the following steps 101-103:
in step 101, a presentation document is transmitted to a participant terminal.
Here, a local area network, such as a local area network for establishing bluetooth connection, may be established, and the presenter terminal and the participant terminal may be connected together through bluetooth, so that the presenter terminal and the participant terminal may communicate with each other and share resources under the support of corresponding network software, and thus, the presenter terminal may directly send a document for presentation to the participant terminal.
Alternatively, fig. 2 is a schematic diagram of a conference presentation system according to an exemplary embodiment, where the system includes a presenter terminal 21, a server 20, and a participant terminal 22, where the presenter terminal 21 and the participant terminal 22 may both download corresponding application clients and connect to the server 20 through the application clients, where the presenter terminal 21 and the participant terminal 22 may construct a conference group in the server 20 through the application clients, so that the presenter terminal 21 may send a presentation document to the participant terminal: the presenter terminal 21 may send a presentation document to the server 20 indicating a presentation to be sent to the participant terminals in the conference group, and the server 20 may forward the presentation document to the participant terminal 22 upon receiving the presentation document. Of course, the server 20 may also generate an access link indicating the address of the presentation document in the server after receiving the presentation document; the server 20 may transmit the access link to the participant terminal 22, and the user of the participant terminal 22 may access the document for obtaining the presentation uploaded by the presenter terminal 21 after clicking the access link.
In step 102, page information corresponding to a page of the document currently displayed by the presenter terminal is sent to the participant terminal, so that the participant terminal and the presenter terminal synchronously display the same page content.
After the presenter terminal sends the document for presentation to the participant terminal, the presenter and the participant of the conference can see the document for presentation through the own terminals, and in order to enable the participant and the presenter to watch the current presentation content simultaneously, the presenter terminal can send page information corresponding to the page of the document currently displayed by the presenter terminal to the participant terminal, the page information comprises parameter information indicating the content displayed by the current page of the presenter terminal, and the participant terminal can control the participant terminal to synchronously display the same page content as the presenter terminal after receiving the page information.
Here, the presenter terminal may directly transmit the page information to the participant terminal, or may transmit the page information to a server, which forwards the page information to the participant terminal.
In one possible embodiment, the page information includes a view of the document, a percentage of page zoom-in, and a percentage of the page content in the document.
For example, when the document for presentation is a word document, the page information that the presenter terminal needs to send to the participant terminal includes a view mode (reading view/page view/web view/outline view/general view) such as page view, a percentage of page enlargement such as 100%, and a percentage of the page content in the document such as a percentage of the page content in the whole document of 0% -10%; thus, after the participant terminal acquires the page information, the participant terminal can be controlled to display the word document according to the page view, the word page is displayed according to the proportion of 100%, and the content of the word page is adjusted to 0% -10% of the whole document. Thus, the participant terminal will display the same content as the presenter terminal. Of course, the presentation document may be PPT (Powerpoint) document, and the presenter terminal needs to transmit the above page information to the participant terminal.
Here, when the type of the document for presentation is a spreadsheet, such as an excel document, the page information further includes a sheet of the current sheet, so that the participant terminal displays the same content as the same sheet displayed by the presenter terminal.
Here, the presenter terminal may transmit current page information to the participant terminal upon detecting that the currently displayed page content is changed; or the presenter terminal may transmit current page information to the participant terminal upon detecting an operation that causes page content to occur.
In step 103, when the ink mark on the page currently displayed by the presenter terminal is detected, the position information of the ink mark on the page currently displayed by the presenter terminal is acquired, and the position information is sent to the participant terminal, so that the participant terminal displays the same ink mark at the same position of the page currently displayed by the participant terminal.
Here, a presenter often enters ink marks on a document to identify where in the document the attention or importance of a participant is needed when making a presentation. In order to enable the participant to see the ink mark and notice the place needing to be noticed or paid attention to, the presenter terminal can acquire the position information of the ink mark on the page currently displayed by the presenter terminal when detecting the ink mark on the page currently displayed by the presenter terminal and send the position information to the participant terminal, so that the participant terminal can control the participant terminal to display the same ink mark at the same position of the page currently displayed. Thus, the participant can see the operations of the presenter on the document, such as page turning, marking and the like, on the own participant terminal in real time.
Here, the presenter terminal may directly transmit the position information to the participant terminal, or may transmit the position information to a server, and the server forwards the position information to the participant terminal.
It should be noted that, when detecting various operation instructions, such as a selection instruction, a thickening instruction, an instruction for changing a word size, and the like, the presenter terminal may send the detected operation instruction to the participant terminal, so that the participant terminal and the presenter terminal may synchronously execute the operations indicated by the operation instructions, so as to ensure that the contents displayed by the presenter terminal and the participant terminal are the same.
According to the embodiment, the presenter terminal can synchronize page information corresponding to the page of the document currently displayed and position information of the ink mark on the page to the participant terminal, after the participant terminal receives the synchronous data, the content displayed on the presenter terminal can be synchronously displayed on the screen of the participant terminal, so that the participant can watch the content demonstrated by the presenter on the participant terminal without being limited by a conference television, the presenter terminal can be used under the condition of power failure, and the information transmitted to the participant terminal only has document content and some state information, so that the synchronization of conference content can be completed by using a small amount of flow, and the resource occupation is small.
In a possible embodiment, step 103 in the conference presentation method described above may also be implemented as the following steps A1 to A3.
In step A1, first display position information of a page currently displayed by the presenter terminal on a display area of the presenter terminal is acquired.
In step A2, second display position information of the ink mark on the display area of the presenter terminal is acquired.
In step A3, determining, according to the first display position information and the second display position information, position information of the ink mark on a page currently displayed by the presenter terminal.
Fig. 3 is a display diagram of a presenter terminal display area according to an exemplary embodiment, where relevant data such as the size of the presenter terminal display area 30 can be confirmed, a coordinate system is established in the presenter terminal display area using the presenter terminal display area 30 as a reference system, as shown in fig. 3, a point O at the upper left corner of the presenter terminal display area is taken as the origin of the rectangular coordinate system, and can be denoted as O (0, 0), two straight lines perpendicular to each other in the display area are taken as the horizontal and vertical axes of the coordinate system, and the coordinate system is established in the presenter terminal display area. The presenter terminal may then determine first display position information of the page 31 currently displayed by the presenter terminal on the presenter terminal display area 30, which may be represented by coordinates in the above-described coordinate system; and determines second display position information of the detected ink mark 32 on the presenter terminal display area 30, which is also represented by coordinates in the coordinate system described above. Finally, the presenter terminal may determine the position information of the ink mark 32 on the page 31 currently displayed by the presenter terminal according to the first display position information and the second display position information, that is, two coordinate information.
In one possible embodiment, the ink mark may be a mark in a fixed format, and when the ink mark is a mark in a fixed format, the position information of the ink mark on the page currently displayed by the presenter terminal includes the format type of the ink mark and the position information of a fixed node of the format type on the page currently displayed by the presenter terminal.
Here, the fixed node is a node capable of determining a specific shape of the ink mark. By way of example, FIG. 4 is a schematic diagram of two ink marks of the type having a regular prismatic format, as shown in FIG. 4A, and requiring only a fixed node to be specified by the presenter when using the ink marks in that format: the positions of the start point 41 and the end point 42 may be such that ink marks of a particular configuration are displayed in the shape shown in figure 4 as a. Therefore, for the ink mark with the regular prism format, the format of the ink mark acquired by the presenter terminal may be the regular prism format, and the position of the start point on the presenter terminal display area, and the position of the end point on the presenter terminal display area, where the second display position information may explicitly identify the position of the ink mark on the presenter terminal display area. Accordingly, when the presenter terminal performs step A3, the determined location information of the ink mark on the page currently displayed by the presenter terminal may include: the ink mark is in a regular prismatic format, the starting point is positioned on the page currently displayed by the presenter terminal, and the end point is positioned on the page currently displayed by the presenter terminal. After the presenter obtains the location information, the presenter may synchronize the location information to the participant terminal.
The fixed-format ink marks shown in the diagram a of fig. 4 are just one of a plurality of mark types, and the fixed nodes in the format types of the marks include not only a start point and an end point, but also one or more intermediate nodes, and at this time, the position information of the ink marks acquired by the presenter terminal on the page currently displayed by the presenter terminal needs to further include the positions of the intermediate nodes on the page currently displayed by the presenter terminal. In this embodiment, only the format type of the ink mark and the position information of each fixed node need to be transmitted, the transmitted information is less, and the determined ink mark is very accurate.
It should be noted that, the ink mark may also be an irregular mark, as illustrated in fig. 4B, and for an ink mark in an irregular format as illustrated in fig. 4B, the position of the current track point of the ink mark on the display area of the presenter terminal may be recorded with a fast frequency, for example, the position information of the track point on the page currently displayed by the presenter terminal may be determined by recording 100 points per second, and transmitted to the participant terminal.
The embodiment can determine the position information of the ink mark on the page currently displayed by the presenter terminal through the first display position information of the page currently displayed by the presenter terminal on the display area of the presenter terminal and the second display position information of the ink mark on the display area of the presenter terminal, so that the method is quick and accurate.
Fig. 5 is a schematic diagram illustrating a conference presentation method according to an exemplary embodiment, as shown in fig. 1, which is used in a participant terminal, and includes the following steps 501-503:
in step 501, a document for presentation by a presenter terminal is received.
Here, referring to the description in the above embodiment, the participant terminal may directly receive the document for presentation sent by the presenter terminal, or may receive the document for presentation sent by the presenter terminal and issued by the server, and the specific implementation process will not be described in detail herein.
In step 502, page information corresponding to a page of the document currently displayed by the presenter terminal is received, and according to the page information, the participant terminal and the presenter terminal are controlled to synchronously display the same page content.
After the presenter terminal sends the document for presentation to the participant terminal, the presenter and the participant of the conference can see the document for presentation through the own terminals, and in order to enable the participant and the presenter to watch the current presentation content simultaneously, the presenter terminal can send page information corresponding to the page of the document currently displayed by the presenter terminal to the participant terminal, the page information comprises parameter information indicating the content displayed by the current page of the presenter terminal, and the participant terminal can control the participant terminal to synchronously display the same page content as the presenter terminal after receiving the page information.
Here, the presenter terminal may directly transmit the page information to the participant terminal, or may transmit the page information to a server, which forwards the page information to the participant terminal.
In one possible embodiment, the page information includes a view of the document, a percentage of page zoom-in, and a percentage of the page content in the document.
For example, when the document for presentation is a word document, the page information that the presenter terminal needs to send to the participant terminal includes a view mode (reading view/page view/web view/outline view/general view) such as page view, a percentage of page enlargement such as 100%, and a percentage of the page content in the document such as a percentage of the page content in the whole document of 0% -10%; thus, after the participant terminal acquires the page information, the participant terminal can be controlled to display the word document according to the page view, the word page is displayed according to the proportion of 100%, and the content of the word page is adjusted to 0% -10% of the whole document. Thus, the participant terminal will display the same content as the presenter terminal. Of course, the presentation document may be PPT (Powerpoint) document, and the presenter terminal needs to transmit the above page information to the participant terminal.
Here, when the type of the document for presentation is a spreadsheet, such as an excel document, the page information further includes a sheet of the current sheet, so that the participant terminal displays the same content as the same sheet displayed by the presenter terminal.
In step 503, receiving location information of a current ink mark on a page currently displayed by the presenter terminal; and controlling the participant terminal to display the same ink mark at the same position of the currently displayed page of the participant terminal according to the position information of the ink mark.
Here, a presenter often enters ink marks on a document to identify where in the document the attention or importance of a participant is needed when making a presentation. In order to enable a participant to simultaneously see the ink mark and further notice the place needing to be noted or paid attention to, the presenter terminal can acquire the position information of the ink mark on the page currently displayed by the presenter terminal when detecting the ink mark on the page currently displayed by the presenter terminal, and send the position information of the ink mark on the page currently displayed by the presenter terminal to the participant terminal; thus, after the participant terminal obtains the position information of the current ink mark on the currently displayed page of the presenter terminal, the participant terminal can be controlled to display the same ink mark at the same position of the currently displayed page.
Here, the presenter terminal may determine the position information of the ink mark on the page currently displayed by the presenter terminal according to the first display position information and the second display position information, that is, the two coordinate information, and transmit the position information of the ink mark on the page currently displayed by the presenter terminal to the participant terminal, and the participant terminal may determine to display the same-shape ink mark at the same position on the same page currently displayed by the participant terminal, and determine the position information of the ink mark on the display area of the participant terminal according to the position information of the page currently displayed by the participant terminal and the position information of the ink mark on the page currently displayed by the participant terminal, and further display the ink mark at the corresponding position of the display area of the participant terminal, so that the participant terminal displays the same ink mark at the same position of the page currently displayed.
In one possible embodiment, the ink mark may be a mark in a fixed format, and when the ink mark is a mark in a fixed format, the position information of the ink mark on the page currently displayed by the presenter terminal includes the format type of the ink mark and the position information of a fixed node of the format type on the page currently displayed by the presenter terminal.
Here, the fixed node is a node capable of determining a specific shape of the ink mark. By way of example, as shown in diagram a of fig. 4, the type of format of the ink mark is a prismatic format, and the presenter only needs to specify a fixed node when using the ink mark in this format: the positions of the start and end points can be used to display ink marks of a particular configuration in the shape shown in figure 4 as a. Therefore, the presenter terminal only needs to determine that the format of the ink mark is a regular prism format, the initial point is positioned on the page currently displayed by the presenter terminal, and the final point is positioned on the page currently displayed by the presenter terminal and is sent to the participant terminal; the participant terminal can display the ink marks in the regular prismatic format with the starting point and the end point of the same position on the page currently displayed by the participant terminal according to the position of the starting point on the page currently displayed by the presenter terminal and the position of the end point on the page currently displayed by the presenter terminal, so that the same ink marks can be displayed at the same position of the document.

In this embodiment, only the format type of the ink mark and the position information of each fixed node need to be transmitted, the transmitted information is less, and the determined ink mark is very accurate.
It should be noted that the ink mark may be an irregular mark, for example, for an ink mark in an irregular format as shown in fig. 4B, the positions where the participant terminals receive a track point may display the corresponding ink at the same positions, so that the same ink mark may be displayed.
According to the embodiment, the presenter terminal can synchronize page information corresponding to the page of the document currently displayed and position information of the ink mark on the page to the participant terminal, after the participant terminal receives the synchronous data, the content displayed on the presenter terminal can be synchronously displayed on the screen of the participant terminal, so that the participant can watch the content demonstrated by the presenter on the participant terminal without being limited by a conference television, the presenter terminal can be used under the condition of power failure, and the information transmitted to the participant terminal only has document content and some state information, so that the synchronization of conference content can be completed by using a small amount of flow, and the resource occupation is small.
In a possible implementation manner, the conference presentation method may further include the following steps B1 and B2.
In step B1, an operation instruction input by a participant is received.
