Detailed Description

The method for displaying the annotation information is suitable for video conferences, including commonly-known telephone conferences, remote network conferences and the like which require a plurality of participants to realize communication data interaction among a plurality of devices through a network.

In order to facilitate understanding of the scheme of the present application, a system configuration architecture to which the scheme of the present application is applied is described. For example, referring to fig. 1, a schematic diagram of a component architecture of a video conference system to which the method for displaying annotation information of the present application is applied is shown.

As can be seen from fig. 1, the video conference system comprises aserver 101 and at least twoelectronic devices 102.

Theelectronic device 102 is connected with theserver 101 through the conference application, and is connected with conference applications in other electronic devices through the conference application, so that communication of video conferences among different electronic devices is achieved.

After the at least two electronic devices realize the communication of the video conference, the electronic devices can share the conference content through the communication channel of the video conference and output the conference content on the electronic devices.

It is understood that the electronic device of the present embodiment may be any form of electronic device, such as a terminal with a display screen, a desktop computer, or an electronic device with a projection function and capable of realizing networking, and so on.

Of course, fig. 1 is only a component architecture of the conference system, and in practical applications, there may be other devices, for example, theelectronic device 101 may also establish a connection with a server through other conference terminals, and the like. The present application does not impose limitations on the specific composition of the conferencing system.

The following describes a method for displaying annotation information according to an embodiment of the present application with reference to the drawings.

For example, referring to fig. 2, which shows a flowchart of an embodiment of a method for displaying annotation information according to the present application, the embodiment is described from an electronic device side participating in a video conference, and the method of the embodiment may include:

s201, receiving the shared content requested to be displayed by one party of the video conference.

In the video conference, each party participating in the video conference is an electronic device of a user. In the embodiment of the application, any one participant of the video conference can request to show the shared content. For example, an initiator initiating a video conference may request the displayed shared content, so that each participant of the video conference may display the content that the initiator needs to display; alternatively, any party to the video conference may request presentation of the shared content from other participants.

The shared content may have various forms, for example, the shared content may be a picture, a document, a PPT, a video file, and the like, which is not limited in this application.

S202, displaying the shared content.

The specific manner of displaying the shared content may also be different according to the specific form of the electronic device.

For example, the electronic device may present the shared content in a display screen. For another example, the electronic device may project the shared content in a projection manner, or the electronic device may output the shared content to a designated display device to present the shared content. Of course, the way the electronic device presents the shared content may also have other ways, which are not listed here.

S203, at least two groups of label information combinations aiming at the shared content are obtained.

Wherein, different combinations of the labeling information are associated with different labels. The annotator is a user participating in the video conference.

The labeling information combination comprises at least one piece of labeling information, and each piece of labeling information is associated with a labeling position. The annotation position is used for indicating a content area of the shared content annotated by the annotator of the annotation information.

And determining the part of the content information in the shared content to be marked by the marking information according to the marking position associated with the marking information. For example, the annotation position can be a coordinate position of the annotation information for the object content annotated by the shared content or identification information for identifying the annotated object content, such as a row identification or a segment identification, and the like.

Since different annotation information combinations are associated with different annotators, at least one of the at least two sets of annotation information combinations acquired by the electronic device is from a participant other than the local user of the electronic device in the video conference. That is to say, in the embodiment of the present invention, the electronic device may obtain both a set of annotation information combinations annotated by the local user for the shared content and at least one set of annotation information combinations from terminals of video conference participants other than the local user.

In the embodiment of the present application, the annotation information may have various situations, such as lines added to the shared content, accents drawn, text annotations added to the shared content, and the like, which is not limited in this application.

Correspondingly, obtaining at least two sets of label information combinations includes the following two cases:

one situation is: and acquiring a group of annotation information combinations of the local user for the shared content annotation and at least one group of annotation information combinations sent by the electronic equipment of at least one video conference participant except the local user.

The other situation is as follows: and acquiring at least two groups of annotation information combinations sent by the electronic equipment of at least two video conference participants except the local user.

Optionally, in the above two cases, in order to obtain a set of annotation information combinations annotated by the local user of the electronic device for the shared content, after the shared content is exhibited by the electronic device, if the electronic device can also receive an annotation request input by the local user of the electronic device. Correspondingly, the electronic device, in response to the annotation request, may determine, according to an annotation operation of the local user on the shared content, at least one piece of annotation information annotated in the shared content by the local user, to obtain an annotation information combination including the at least one piece of annotation information annotated by the local user.

As an optional manner, when the local user performs a tagging operation on the shared content, at least one piece of tagging information tagged by the local user may be displayed in the shared content.

It can be understood that, since the local user may perform the annotation operation on the displayed shared content at different times, each time the electronic device detects that the local user performs the annotation operation on the shared content, the currently annotated annotation information of the local user (or the annotation information annotated by the local user at the current time and the annotation information annotated before the current time) may be displayed, and the currently annotated annotation information of the local user is added to the annotation information combination of the local user.

It can be understood that, after the electronic device obtains the annotation information combination of the local user, the local annotation information combination can also be sent to the electronic devices of other conference participants besides the local user, so that the electronic devices of other conference participants can obtain the annotation information combination of the local user.

Correspondingly, the electronic device can also receive the annotation information combination sent by the electronic devices of other conference participants, so that the electronic device can acquire the annotation information combination indicated in the shared content by one or more conference participants besides the local user.

And S204, determining the target annotation information combination to be displayed currently from the at least two groups of annotation information combinations.

Under the condition that the electronic equipment locally acquires multiple groups of labeling information combinations, the electronic equipment can determine the labeling information combinations which need to be displayed currently from the multiple groups of labeling information combinations, and in order to facilitate distinguishing, the determined labeling information combinations to be displayed are called target labeling information combinations.

There are many possible specific ways of determining the combination of the target labeling information. For example, in one possible case, the target annotation information combination selected by the user for presentation can be determined from the at least two sets of annotation information combinations. For example, an identifier of each annotation information combination, such as a serial number of each annotation information or an identifier of a annotator, may be displayed in the electronic device, and the user selects each annotation information combination, and the electronic device may determine a target annotation information combination according to a selection operation of the user.

And S205, respectively displaying each piece of labeling information in the target labeling information combination on the upper layer of the shared content according to the labeling position associated with each piece of labeling information in the target labeling information combination.

According to the labeling position associated with each piece of labeling information, the labeling of the inside of which part of the shared content is performed by each piece of labeling information can be determined respectively. Correspondingly, the annotation information is displayed on the upper layer of the shared content according to the annotation position associated with the annotation information, so that the actual annotation condition of the annotator in the shared content can be restored, and the local user can know the annotation of the annotator on the shared content.

In the embodiment of the present application, in the process of participating in the video conference by the electronic device, if different participants from the video conference are acquired, and aiming at least two groups of annotation information combinations of the shared content in the video conference, the target annotation information combination which needs to be displayed currently can be determined, because each piece of annotation information in the target annotation information combination is associated with the annotation position of the annotator for annotating the shared content, therefore, according to the labeling position of each piece of labeling information in the target labeling information combination, each piece of labeling information in the target labeling information combination can be displayed on the upper layer of the shared content, therefore, the local user of the electronic equipment can intuitively know the related annotation information of the user and other conference participants on the shared content in the video conference, and further, the content information of different conference participants who have a question or focus on the shared content can be flexibly and conveniently known.

It will be appreciated that in practical applications, a local user of the electronic device may also wish to simultaneously learn the annotation of the shared content by multiple conference participants of the video conference. To achieve this object, in this embodiment of the application, the electronic device may further receive an integrated annotation information combination transmitted by the server, where the integrated annotation information combination includes a plurality of pieces of annotation information belonging to at least two video participants, and the integrated annotation information is generated by the server according to the annotation information combination of at least two video participants.

Of course, the electronic device may also receive a full label display instruction of the local user, where the full label display instruction is used to indicate that the at least two groups of obtained label information combinations are displayed. Accordingly, the electronic device can simultaneously display the acquired annotation information in each group of annotation combination on the upper layer of the shared content.

It will be appreciated that in practice, the shared content is conveniently annotated by different participants of the video conference without affecting the presentation of the shared content. In this embodiment of the present application, the annotation information of the video conference participant on the shared content may be presented in an annotation layer constructed by the electronic device of the video conference participant. For example, before the video participant annotates the shared content, the electronic device of the video participant constructs a transparent layer on the displayed shared content, where the transparent layer is an annotation layer, so that the video participant can annotate the shared content on the annotation layer on the premise of viewing the shared content.

For example, referring to fig. 3, which shows a flowchart of another embodiment of the method for displaying annotation information according to the present application, where the flowchart of this embodiment takes an example that each annotator presents annotation information annotated to shared content on an annotation layer, and the embodiment joins an electronic device side description of a video conference, the embodiment may include the following steps:

s301, receiving the shared content requested to be displayed by one party of the video conference.

S302, displaying the shared content.

The above two steps can be referred to the related description of the previous embodiment, and are not described herein again.

S303, acquiring at least two labeling layers aiming at the shared content.

The label layer is a transparent layer presenting each label information in a group of label information combinations. In this embodiment, each annotation layer is associated with a annotator, and different annotation layers are associated with different annotators. The annotators are conference participants participating in the video conference. For example, each annotation layer is associated with an identifier of a annotator, and the identifier of the annotator may be an account number of a conference participant, a conference number, or the like.

Optionally, on the premise that the annotation layer has a one-to-one correspondence with the coordinate of the shared content, the specific presentation position of each piece of annotation information on the annotation layer is the annotation position associated with the piece of annotation information. For example, there is a coordinate correspondence between the annotation layer and the shared content, for example, four vertex coordinates of the annotation layer correspond to coordinates of four points of the shared content, so that, according to the coordinate correspondence, when the annotation layer is displayed on the upper layer of the shared content, the display position of the annotation layer on the upper layer of the shared content is fixed, and the position of each piece of annotation information in the corresponding annotation layer is also fixed, so that it is not necessary to determine the annotation position for each piece of annotation information separately.

It can be understood that, similar to the foregoing embodiment, the at least two annotation layers obtained in this embodiment may have the following two cases:

one situation is: acquiring a label layer labeled by a local user aiming at the shared content and at least one label layer sent by electronic equipment of at least one video conference participant except the local user;

in another case, at least two annotation layers sent by the electronic devices of at least two video conference participants except the local user are obtained.

In the above two cases, in order to obtain the annotation layer labeled by the local user, in the embodiment of the application, after the shared layer is displayed, if the electronic device receives an annotation request input by the local user, a transparent local annotation layer associated with the local user is created on the upper layer of the shared content. And the annotation request is used for requesting annotation operation in the shared content. Correspondingly, the electronic device may record at least one piece of label information on the local label layer according to a label operation of the local user on the local label layer. For convenience of distinguishing, the label layer of the local user is referred to as a local label layer.

If the local user already has the associated annotation layer, the annotation layer does not need to be repeatedly created, and only the annotation operation of the local user is needed, at least one piece of annotation information currently annotated by the user is recorded on the annotation layer associated with the local user, so that the annotation layer can include one or more pieces of annotation information annotated at the current time of the user and before the current time.

In addition, in order to enable other participants of the video conference to obtain the annotation layer annotated by the local user, the electronic device may further send the local annotation layer to electronic devices of other conference participants besides the local user.

Optionally, in consideration that after the electronic device sends the local annotation layer to the electronic device of another video conference, a local user may still add new annotation information on the local annotation layer, on this basis, the electronic device may send at least one piece of annotation information currently recorded in the local annotation layer to the electronic device of another conference participant, so that the terminal of the other conference participant displays the at least one piece of annotation information in the local annotation layer corresponding to the local user. If the electronic equipment sends a local labeling layer to other conference participants, only at least one piece of newly added labeling information needs to be sent; and if the electronic equipment does not send the local annotation layer to other conference participants, sending the local annotation layer containing the at least one piece of annotation information recorded currently to the electronic equipment of other conference participants.

Correspondingly, in order that the electronic device can acquire the annotation layers annotated by other video conference participants, the electronic device can also receive the annotation layers sent by the electronic devices of other video conference participants except the local user, and each annotation layer is associated with an annotator.

It can be understood that, because different annotation layers are associated with different annotators, in order to distinguish the annotation layers of different annotators and facilitate subsequent local users to quickly find out the annotation layer of a concerned annotator from the annotation layers of multiple annotators, after multiple annotation layers are obtained, the multiple annotation layers can be displayed in an overlapping manner, and a distinguishing identifier is set on each annotation layer and used for distinguishing the annotators of different annotation layers. For example, the identifier of the annotator can be added on the side edge of each annotation layer; for another example, the border of each annotation layer may be set to the color representing the annotator, and the color setting of the borders of different annotation layers is different.

For example, referring to fig. 4, which shows a schematic diagram of an electronic device overlapping multiple annotation layers, it can be seen from fig. 4 that aannotator display area 402 is provided on the right side of eachannotation layer 401, and an identifier representing an annotator is provided in theannotator display area 402. The positions of the display areas of the markers in different representation layers can be different, so that the markers of the markers in the display areas of the markers can not be checked, and the display areas of the markers of different icons can not be covered with each other. As shown in fig. 4, the identifiers of the annotators, which are respectively user 1, user 2, user 3 and user 4, are sequentially displayed in the annotator display areas of the multiple annotation layers.

S304, determining a target labeling layer to be displayed currently from the at least two labeling layers.

In order to facilitate the distinction, in the embodiment of the present application, a currently to-be-displayed labeling layer is referred to as a target labeling layer.

And S305, displaying the target annotation layer on the upper layer of the shared content according to the annotation position associated with each piece of annotation information in the target annotation layer, so as to display each piece of annotation information for the shared content in the target annotation layer.

It can be understood that, on the premise that the target annotation layer has a coordinate corresponding relationship with the shared content, the target annotation layer may be displayed on the upper layer of the shared content according to the coordinate corresponding relationship, so that the coordinate position of each annotation position on the upper layer of the shared content on the target annotation layer is consistent with the annotation position corresponding to the annotation information.

When the target annotation layer is displayed on the upper layer of the shared content, other annotation layers except the target annotation layer can be displayed on the lower layer of the shared content in an overlapping manner.

In a possible implementation manner, the obtained multiple annotation layers may be displayed simultaneously on the upper layer of the shared content, and the multiple annotation layers are displayed in an overlapping manner, but the target annotation layer is displayed on the uppermost layer, and each piece of annotation information on the target annotation layer is displayed in the target annotation layer, and the annotation information in other annotation layers is not displayed.

In order to highlight the target annotation layer, after the target annotation layer is displayed on the upper layer of the shared content, the electronic device may further set the target annotation layer to have a special display effect, for example, set the target annotation layer to be in a highlighted state.

It can be understood that, in the embodiment of the present application, only the annotation layer of the local user may be stored in the electronic device, and the annotation layer sent by the other video participants is instructed to be cached; of course, in order to analyze the related discussion content involved in the video conference subsequently, the electronic device may also store and acquire the at least two annotation layers.

Of course, the above is described with the server generating the comprehensive annotation layer as an example, in practical applications, the electronic device may further generate, based on the at least two annotation layers, the comprehensive annotation layer including all annotation information in the at least two annotation layers after the at least two annotation layers are obtained, and display the comprehensive annotation layer on an upper layer of the shared content.

To facilitate understanding of the solution of the present application, the following describes a method for displaying annotation information from interaction between at least two electronic devices in a video conference, for example, referring to fig. 5, which shows a flowchart of another embodiment of the method for displaying annotation information of the present application, where this embodiment refers to one of the electronic devices as a first electronic device and refers to other electronic devices that establish a video conference with the first electronic device as a second electronic device, and this embodiment may include:

s501, the first electronic device receives the shared content requested to be displayed by one party of the video conference.

If the local user of the first electronic device initiates a content sharing request to the first electronic device, the first electronic device displays the shared content based on the content sharing request of the user; meanwhile, the first electronic device can also request the other conference participants in the video conference to show the shared content, so that the second electronic devices of the other conference participants can show the shared content.

As another example, a first electronic device receives shared content requested for presentation by a second electronic device of other video conference participants.

S502, the first electronic device displays the shared content.

S503, when the first electronic device receives a labeling request input by a local user, the first electronic device creates a transparent local labeling layer associated with the local user on the upper layer of the shared content.

And the annotation request is used for requesting annotation operation in the shared content.

In order to distinguish the annotation layer constructed on the second electronic device side, the layer constructed on the first electronic device side for the local user of the first electronic device is called a local annotation layer.

The layer constructed on the shared content can be regarded as a virtual transparent layer, so that the label information of the user can be presented on the transparent layer, and the shared content cannot be changed.

S504, the first electronic device records at least one piece of label information on the local label layer according to the label operation of the local user on the local label layer.

It can be understood that, in the case that the first electronic device displays the shared content, if the first electronic device only has a local annotation layer for the shared content, the first electronic device may maintain the local annotation layer annotated with annotation information on the shared content, so that the local user may know about its annotation on the shared content during the video conference.

And S505, the first electronic device receives the public authority information set for the local annotation layer by the local user.

The public authority information is used for representing conference participants who have the local annotation layer for watching in the video conference.

If the first electronic device can set the disclosure permission of the conference participant a to "disclosure", it indicates that the local annotation layer is allowed to be sent to the electronic device of the conference participant a, so that the conference participant a can see the local annotation layer labeled by the local user. For another example, the first electronic device may set the disclosure permission of the conference participant B to "not disclose" (or "prohibit"), and the conference participant B does not have the permission to view the local label layer labeled by the local user.

S506, the first electronic device determines at least one target conference participant having the local annotation layer in the video conference according to the public authority information of the local annotation layer.

And S507, the first electronic device sends at least one piece of currently recorded annotation information in the local annotation layer to the second electronic device of the at least one target conference participant.

For convenience of distinguishing, the conference participant who has the local annotation layer for viewing the first electronic device side is called a target conference participant.

Sending at least one piece of currently recorded annotation information in the local annotation layer to the second electronic device may be sending the local annotation layer, so that the target conference participant can view all the annotation information in the local annotation layer; or sending at least one piece of currently newly added annotation information in the local annotation layer to the second electronic device, so that the second electronic device displays the at least one piece of annotation information on the local annotation layer corresponding to the local user on the first electronic device side.

And S508, the first electronic device receives the annotation layer sent by the second electronic device of at least one conference participant.

Wherein, the label layer is associated with a label.

It can be understood that, similar to the operation that can be performed by the local user on the first electronic device side, other conference participants in the video conference may label the shared content on their own second electronic devices, and may set the public right information of the label layer of the conference participants. Correspondingly, if a conference participant at the second electronic device sets that a local user at the first electronic device has a label layer for viewing the conference participant, the second electronic device may send the corresponding label layer to the first electronic device.

S509, the first electronic device determines at least two currently acquired annotation layers for the shared content, and displays the at least two annotation layers in an overlapping manner, where each annotation layer is provided with a distinguishing identifier.

The distinguishing mark is used for distinguishing the annotators of different annotation layers. The distinguishing mark can be referred to the related introduction.

It can be understood that, in a case where the first electronic device constructs a local annotation layer and receives at least one annotation layer sent by the second electronic device, the first electronic device may obtain at least two annotation layers, where the at least two annotation layers may include a local annotation layer on the first electronic device side. Accordingly, the electronic device may display the at least two annotation layers in an overlapping manner, for example, display the at least two annotation layers in an overlapping manner on the lower layer of the shared content.
