[0061] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] With the increasing demand for remote collaboration, multi-role collaborative electronic whiteboards have gradually become an important tool for office and teaching. However, the existing technology has many problems in terms of permission management, independent perspective control, and dynamic permission adjustment during multi-role collaboration. In particular, it is difficult to meet the needs of efficient collaboration in terms of permission control and perspective management during the collaboration process. Therefore, there is an urgent need for a multi-role management method, device, equipment, and medium for electronic whiteboards to manage permissions and perspectives in multi-role collaboration to improve collaboration efficiency and user experience.

[0063] Embodiment 1

[0064] Please refer to Figure 1 , which is a step flow chart of a multi-role management method of an electronic whiteboard provided by an embodiment of the present invention, including steps S101 to S103.

[0065] Step S101: Obtain user information of the electronic whiteboard, and generate a permission control matrix based on the user information.

[0066] In an optional embodiment, the user information of the electronic whiteboard is obtained, and the user information includes: the user's role type (such as initiator, collaborator); the initial permissions are automatically assigned according to the user information, and a permission control table (i.e., permission control matrix) is generated. The permission control table is composed of a matrix P = {p ij}, where p ij Indicates the permission of role i for operation i.

[0067] It should be noted that user information can be obtained through the identity authentication information provided by the user when logging into the electronic whiteboard or the role data assigned by the electronic whiteboard; the dimension of the permission control matrix depends on the number of users and the number of operations on the electronic whiteboard. After completing the initialization of the permission control matrix, the permission data structure corresponding to the permission control matrix is ​​generated to verify the permissions of the user's subsequent operation requests, ensuring that each user of the electronic whiteboard can only perform operations within the scope of his or her permission.

[0068] Step S102: identifying the operation request of each user in the electronic whiteboard collaboration process, wherein the operation request includes: a viewing angle adjustment request, a whiteboard content editing request, and a permission adjustment request.

[0069] Step S103: Obtaining the authority of each user according to the authority control matrix, and responding to the user's viewing angle adjustment request, whiteboard content editing request and authority adjustment request to achieve multi-role management of the electronic whiteboard.

[0070] It should be noted that in the multi-role management of the electronic whiteboard, when a user issues an operation request, the operation is executed, the operation request and the corresponding operation target object information are obtained in real time, and the user is verified based on the authority control matrix to see whether he has the authority to perform the operation. The specific verification process is to query the corresponding element p in the authority control matrix. ij Whether the value of is "allowed", this embodiment sets p ij A value of 1 indicates that the operation is allowed; then the corresponding Boolean value (true / false) is generated according to the verification result to indicate whether the operation request is executed. If the verification is passed, the user's operation request is responded to according to the following steps, and the operation result is reflected on the whiteboard content; otherwise, the operation request is rejected and the result is fed back to the user of the electronic whiteboard.

[0071] In this embodiment, the process of obtaining the authority of each user according to the authority control matrix and responding to the user's viewing angle adjustment request, whiteboard content editing request and authority adjustment request to realize multi-role management of the electronic whiteboard specifically includes:

[0072] When the operation request is a viewing angle adjustment request, identifying the viewing angle adjustment request, calculating a parameter set for viewing angle adjustment, and obtaining the authority of the user corresponding to the viewing angle adjustment request according to the authority control matrix to respond to the viewing angle adjustment request of the user;

[0073] When the operation request is a whiteboard content editing request, obtaining the editing content and editing object corresponding to the whiteboard content editing request, and obtaining the authority of the user corresponding to the whiteboard content editing request according to the authority control matrix, so as to respond to the user's whiteboard content editing request;

[0074] When the operation request is a permission adjustment request, the permission of the user corresponding to the permission adjustment request is obtained according to the permission control matrix to respond to the user's permission adjustment request.

[0075] This embodiment obtains the authority of each user based on the authority control matrix, realizes the response to the operation requests of different operation types of users, and completes the multi-role management of the electronic whiteboard. The authority control matrix ensures that each user of the electronic whiteboard can only perform operations within the scope of his authority, avoids the confusion of operation requests of different users leading to low efficiency of electronic whiteboard collaboration, and improves the efficiency of multi-role management of the electronic whiteboard.

[0076] In this embodiment, when the operation request is a viewing angle adjustment request, identifying the viewing angle adjustment request, calculating a parameter set for viewing angle adjustment, and obtaining the authority of the user corresponding to the viewing angle adjustment request according to the authority control matrix to respond to the viewing angle adjustment request of the user, specifically includes:

[0077] When the operation request is a viewing angle adjustment request, identifying the viewing angle adjustment request, and obtaining zoom ratio information, translation amount information, rotation angle information, and layer depth information of the electronic whiteboard;

[0078] Constructing a parameter correction function according to the authority matrix;

[0079] The scaling ratio information, translation amount information, rotation angle information and hierarchical depth information are parameter-corrected according to the parameter correction function to obtain a parameter set for viewing angle adjustment; wherein the parameter set for viewing angle adjustment is specifically:

[0080] V={v i |v i =f(P,u i )},

[0081] Among them, V is the parameter set for viewing angle adjustment, v i is the parameter value, u i is the user request value, f(P,u i ) is a parameter correction function;

[0082] Acquire the authority of the user corresponding to the viewing angle adjustment request according to the authority control matrix to obtain the adjustment range of the viewing angle adjustment request;

[0083] The viewing angle of the electronic whiteboard is adjusted according to the adjustment range of the adjustment request and in combination with the parameter set for viewing angle adjustment, thereby completing the response to the viewing angle adjustment request of the user.

[0084] It should be noted that the zoom ratio information is used to characterize the zoom degree of the electronic whiteboard interface, thereby adjusting the range of content displayed on the electronic whiteboard; the translation information is used to characterize the displacement of the electronic whiteboard interface in the horizontal and vertical directions, so as to adjust the display position of the electronic whiteboard content in the user's perspective; the rotation angle information is used to characterize the rotation angle of the electronic whiteboard content; the hierarchical depth information is used to characterize that the electronic whiteboard may have multiple levels in a three-dimensional scene, so as to represent the depth adjustment of the user's perspective.

[0085] In an optional embodiment, the authority of the user corresponding to the perspective adjustment request is obtained according to the authority control matrix, and then it is determined whether the current perspective adjustment affects the personal perspective or the global perspective, that is, it is determined whether the current perspective adjustment request is to adjust the personal perspective of the user who issued the perspective adjustment request, or to adjust the perspectives of all users of the electronic whiteboard. When the user is the initiator and has global authority, the adjustment range of the perspective adjustment request includes: global perspective and personal perspective; when the user is a collaborator and does not have global perspective authority, the adjustment range of the perspective adjustment request is only personal perspective.

[0086] In an optional embodiment, when multiple users issue perspective adjustment requests, the perspective adjustment requests of users with higher priorities are responded to first based on the user's authority priority (such as the initiator's authority priority is higher than that of collaborators). The perspective adjustment requests of users can also be responded to based on their historical operating behaviors. When a user frequently updates his personal perspective, the perspective adjustment requests of that user are set to personal adjustment priority by default. At this time, only the update of the personal perspective is considered without updating the global perspective.

[0087] This embodiment can determine the parameter set for the perspective adjustment by identifying the perspective adjustment request, and obtain the adjustment range of the perspective adjustment request based on the permission control matrix, thereby realizing the perspective adjustment request response based on the permission control matrix, ensuring the accuracy of the perspective of multiple roles during the electronic whiteboard collaboration process, avoiding the situation where the electronic whiteboard's perspective is confused due to different perspective adjustment requests from multiple users, and thus improving the efficiency of multi-role management of the electronic whiteboard.

[0088] In this embodiment, when the operation request is a whiteboard content editing request, obtaining the editing content and editing object corresponding to the whiteboard content editing request, and obtaining the authority of the user corresponding to the whiteboard content editing request according to the authority control matrix to respond to the user's whiteboard content editing request, specifically includes:

[0089] When the operation request is a whiteboard content editing request, obtaining the editing content and editing object corresponding to the whiteboard content editing request;

[0090] Obtaining the authority of the user corresponding to the whiteboard content editing request according to the authority control matrix to obtain the user's whiteboard editing authority;

[0091] Get the update scope of the whiteboard content according to the user's whiteboard editing authority;

[0092] According to the update range of the whiteboard content, the content of the electronic whiteboard is edited in combination with the editing content and the editing object, thereby completing the response to the user's whiteboard content editing request.

[0093] In an optional embodiment, the update scope of the whiteboard content is obtained based on the user's whiteboard editing permissions, and it is determined whether the current update scope of the whiteboard content is a global update or a local update. When the update scope is a global update, a data packet is generated based on the edited content and the edited object, and then the interface of all users of the electronic whiteboard is updated according to the data packet to achieve the effect of updating the whiteboard content; when the update scope is a local update, a data packet is generated based on the edited content and the edited object, and then the personal interface of the user who issued the whiteboard content editing request is updated according to the data packet to achieve the effect of updating the whiteboard content.

[0094] In this embodiment, when the operation request is a permission adjustment request, obtaining the permission of the user corresponding to the permission adjustment request according to the permission control matrix to respond to the user's permission adjustment request specifically includes:

[0095] When a user issues a permission adjustment request, the user is identified as an initiator or a collaborator; the initiator has the authority to change and assign permissions to collaborators. When the user's permissions change, the permission control matrix corresponding to the user is updated synchronously to generate a new permission data structure to ensure that each user's operating permissions meet the requirements of the permission control matrix.

[0096] It should be noted that when using an electronic whiteboard, users need to provide corresponding role information to ensure the integrity of the role information. When a user issues an operation request, the corresponding permission value is queried according to the permission control matrix, and the operation request is responded to according to the permission value. If the permission is insufficient, the operation request is rejected. When the operation request is a view adjustment request, it is necessary to determine whether the view adjustment is effective for all collaborators; when the operation request is a whiteboard content editing request, it is necessary to determine whether the whiteboard content editing is synchronized to the interface of all collaborators; when the operation request is a permission adjustment request, it is necessary to determine whether the user who makes the permission adjustment request has the permission to adjust the permission. If not, the permission adjustment request is rejected.

[0097] In an optional embodiment, when a user's operation request is rejected, the user is notified in the form of a pop-up window or prompt box, and a feasible next operation suggestion is provided. After the user makes an operation request, the user's interface is updated in real time to ensure that the user can receive the operation result in time. When the operation request is a synchronous operation, the interface of other collaborators must also be updated synchronously. When the user's permissions change, the user is notified in the form of a notification bar or pop-up window to indicate the new permission status.

[0098] In an alternative embodiment, please refer to Figure 2 , is a flowchart of another method for managing multiple roles of an electronic whiteboard provided by an embodiment of the present invention. Figure 2As shown, first, the electronic whiteboard system and role information are initialized, and the permission control based on the role information is implemented through the permission control matrix; under multi-role collaboration, perspective management is implemented according to the permission control matrix, including adjusting personal perspective and synchronous perspective, and independently editing whiteboard content; when independently editing whiteboard content, it is determined whether it is personal editing or synchronous editing; when it is adjusting the synchronous perspective or synchronous editing, all collaborator interfaces are updated; when it is adjusting the personal perspective or personal editing, the personal interface is updated, and finally, the role permissions are dynamically adjusted through the permission control matrix, and the user is notified of the permission change.

[0099] This embodiment can determine the editing content and editing object by identifying the whiteboard content editing request, and obtain the update scope of the whiteboard content editing request based on the permission control matrix, thereby realizing the whiteboard content editing request response based on the permission control matrix, ensuring the accuracy of the whiteboard content display of each user in the electronic whiteboard collaboration process, avoiding the situation where the electronic whiteboard content is confused due to different whiteboard content editing requests from multiple users, and thus improving the efficiency of multi-role management of the electronic whiteboard.
