Detailed ways

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. It should also be noted that, for ease of description, only some, but not all, of the structures related to the present invention are shown in the drawings.

Embodiment 1

FIG. 1 is a flowchart of a method for sharing a conference record according to a first embodiment of the present invention. The present embodiment is applicable to a variety of display content annotations. The method may be performed by an interaction device provided by an embodiment of the present invention. The device may be implemented by means of software and/or hardware. The device may be integrated in any device that provides a display of the content, such as a smart interactive tablet, as shown in FIG.

Step S101: Detecting an annotation operation track generated on the display background.

In the embodiment of the present invention, the display background is displayed on the interaction device, and the interaction device includes a touch function, such as a smart interaction tablet. An annotation record of the displayed content during the conference is realized by the operation of the smart interaction tablet. It should be noted that the display background is merely a simple background color, and may be a preset background without a specific meaning in the conference board book, or a slide page having a specific display content. The annotation operation track here is not only the underline, the key circle, etc., but also the handwritten input text, the drawn graphic track, and the like.

Step S102: Generate and save an annotation record picture including a display background and an annotation operation track.

Specifically, when the user uses the interactive device, in order to make the viewer more clearly and clearly understand what the user is talking about, the user usually performs annotation on the interactive device. The method of annotation can be operated by computer or directly on the display through the touch screen. As the user performs an annotation operation on the touch screen, the touch screen will detect the corresponding touch track.

The annotation operation track is output as important information during the conference and needs to be saved accordingly.

Step S103: Generate a two-dimensional code according to the saved address of the annotation record picture, and display the two-dimensional code.

The annotation record picture is saved in a preset storage device, such as a dedicated picture server, cloud storage, or even an interactive device that generates an annotation record picture for local storage. For the multiple annotation record pictures formed during the current conference, they can be saved in the same directory or added to a file for saving. That is to say, the corresponding multiple annotation record pictures in the current conference have the same save address, based on The saved address generates a two-dimensional code, and the two-dimensional code can be displayed during the conference or after the conference. The user can directly access the save address by scanning the two-dimensional code to obtain an annotation record picture, that is, the output of the important information of the current conference. The annotation record picture can be saved periodically or once at the end of the conference. For the period save method, even if the user conference is absent from the conference, the save address can be obtained by scanning the QR code before leaving the conference, and by accessing the save address, The storage space gets the latest generated annotation record picture in the conference process. For the user, there is no need to access the conference terminal through the mobile storage device to perform data transmission one by one, and multiple users can access the save address to access at the same time, and quickly obtain all the annotation record pictures generated during the conference.

In summary, the embodiment detects an annotation operation track generated on the display background; generates and saves an annotation record picture including the display background and the annotation operation track; and generates a two-dimensional code according to the save address of the annotation record picture. , displaying the two-dimensional code. The user obtains the conference record by scanning the QR code to access the storage address of the conference record. The conference record can be simultaneously transmitted by multiple people and contactless transmission, thereby realizing the fast sharing of the conference record.

Embodiment 2

FIG. 2 is a flowchart of a method for sharing a conference record according to Embodiment 2 of the present invention. The method of this embodiment includes:

In step S201, it is confirmed that the control instruction entering the annotation mode is detected, and the annotation toolbar is displayed in a delayed manner, and only the display background is displayed while the background is displayed, and the first background is obtained by taking a screen shot.

During the conference, the annotation button and the share button with the set shape are displayed in the setting area of the display screen (generally on the left or right side or the left and right sides of the screen), and the user touch operation on the screen is monitored in real time, when received When the user clicks the comment button, the annotation writing mode is entered.

Start the annotation related initialization operation, intercept the current background as the canvas of the annotation writing software; in order to ensure the user's sensory experience and the originality of the annotation record, delay the display of the annotation toolbar before the global screen capture, at the same time, send a broadcast notification The system menu is hidden on the tablet, and then the screen capture is performed; this ensures that the cut background image will not be mixed with various menus; after the screen capture is completed, the notification is sent to let the system menus resume display, and the annotations are called at this time. The toolbar is officially entered into the comment writing state. The writing process on the canvas is realized by touch detection, and the handwriting is displayed in real time in response to user operations. It should be noted that the delay display of the annotation toolbar is very short, and it can be only a few milliseconds. The current background is intercepted in these milliseconds. After the background capture is completed, the annotation toolbar is displayed because the delay time is very high. Short, delayed background interception is not even visually perceived by the user.

Step S202: Detecting an annotation operation track generated on the display background.

During the annotation process, because the annotation operation track is different from the background image generation time and source, the corresponding image can be separately cached during the annotation operation track generation process.

Step S203: superimposing the detected annotation operation track and the first picture to generate an annotation record picture.

After the user's annotation operation is completed, when the user clicks the share button on the display screen, the cached annotation operation track is superimposed on the first picture generated in step S201 to generate an annotation record picture. This superimposed process is performed entirely in the background and does not interfere with the display of the content and the continuous operation of the user. The annotation record picture can be saved as progressive JPEG (Baseline JPEG) and stored in the temporary folder of this machine. The background image and the annotation operation track separately process the final composite annotation record picture, and the image to be processed is small each time, and the data complexity is low.

Step S204: Request the first token for permitting login and the second token for permitting uploading of the annotation record picture to the sharing server.

Step S205: When the first token and the second token are successfully acquired, the save address for saving the uploaded annotation record picture is received.

Specifically, after generating the annotation record picture, the user further responds to the sharing instruction shared by the user. Next, the request server backend will be obtained to obtain two tokens, which are the first token (login token) that the user logs in and the second token that allows uploading the annotation record picture. The login token uses the token value to determine the login status of the user. It is similar to the long string after MD5 encryption. After the user logs in successfully, the sharing server generates a unique value based on the client (ie, conference device) information. This value is Token value. The token value will be saved in the sharing server, and the token value will be used later to retrieve the corresponding user information and determine the login status of the user. After the user logs in successfully, the sharing server returns the generated token value to the client, and the token value is also saved on the client. Later, when the client sends a new network request, it will automatically attach the token value (as a parameter to the sharing server). The share server compares the token value passed by the client with the token value stored in the database to determine the user identity and login status. If the client does not have this token value, it means that no login has been successful, and the user is prompted to log in. If the client has a token value, the login is considered successful and the user is not required to log in again. The working mechanism of the second token (upload token) is similar to that of the first token, with the difference being the right to confirm the upload of the annotation record picture.

When the sharing server allocates the first token and the second token, the sharing server also allocates an address corresponding to the storage space for saving the annotation record picture (ie, saves the address), and saves the address as a URL (Uniform Resource Locator). In the way of recording, after receiving the saved address, the client uploads the annotation image and the generation of the two-dimensional code according to the saved address, and then realizes the sharing of the annotation record image through the sharing of the two-dimensional code. The process of acquiring tokens and saving addresses in this scheme based on cloud storage is similar to the processing of a dedicated sharing server.

It should be specially stated that if you store the annotations directly in the local record, you do not need to obtain the token. The save address can be set by the system default or by the user. At this time, the QR code is generated directly according to the local save address. After scanning the QR code, directly access the corresponding save address to obtain the annotation record picture.

Step S206: Upload the annotation record picture to the storage space corresponding to the save address in the sharing server for saving.

Step S207, prompting to set an access password of the annotation record picture, and receiving an access password set by the user.

Step S208: Generate a two-dimensional code according to the saved address of the annotation record picture, and display the two-dimensional code.

Step S206, step S207, and step S208 may be sequentially performed, that is, first uploaded to the sharing server, setting an access password after the upload is completed, generating a two-dimensional code according to the saved address, and displaying the two-dimensional code. However, based on progressive JPEG, multiple steps can be performed simultaneously, for example, a QR code is provided during the upload process for the user to access the shared meeting record.

After the token is successfully obtained, the client generates a QR code image according to the saved address. The operation of generating the QR code here is placed on the client because such different clients can generate different size specifications and patterns according to their own needs. Dimension code; at the same time, upload the corresponding annotation record under the local temporary folder, in order to ensure a better user experience, when the image is large, the annotation record is allowed to be uploaded to the sharing server 30% when responding to the user. Scan the QR code for access, and the sharing server gradually forwards the received binary stream of the image to the client for progressive display (this is supported by progressive JPEG), that is, when the large file is uploaded to 30% or When the user scans the QR code, the annotation record starts to be displayed. As the upload progress progresses, the record is gradually displayed.

In this embodiment, an encryption switch is provided for the user to perform encryption and decryption setting selection. When the user clicks the encryption switch, the program generates a random password (a numeric keypad is provided in the UI interface of the program, and the user if random If the password is not satisfactory, you can also reset the password of the annotation record. In essence, you can also set an initial password for the entire conference device. All the annotation records uploaded from the conference device use the same password, and correspond to the QR code. The annotation record token B performs the encryption command transmission of the sharing server, and after the sharing server receives the encryption instruction, the sharing operation limits the access to the annotation record. If the user scans the two-dimensional code at this time, the sharing server returns a page for inputting the password; When the user selects the decryption, the decryption instruction and the corresponding annotation record token B are sent to the sharing server, and the sharing server cancels the access restriction after checking the password.

Step S209, confirming that a new annotation operation track is generated on the basis of the original annotation operation track, and outputting the meeting record update reminder after the new annotation operation track interruption reaches the preset time length.

When the user clicks the share button to upload and share the annotation record, the user is monitored in real time whether there is a new writing operation. If the writing content changes, the timer is counted down, and after the countdown ends, the user is prompted whether to update the annotation record; The timing is re-timed every time the user writes, which prevents the timer from popping up to affect the consistency of the user's operation. Of course, the user can also choose to silently update the annotation record.

Step S210: When the two-dimensional code scaling instruction is detected, the displayed two-dimensional code is reduced or enlarged according to the two-dimensional code scaling instruction.

The two-dimensional code scaling instruction is specifically reduced or enlarged by, for example, a mouse wheel operation, or may be reduced or enlarged by a touch operation on the touch display screen.

In addition to the foregoing, there are other ways in which this solution can be implemented. For example, in this solution, after the control instruction entering the annotation mode is detected, the annotation toolbar is directly displayed, and the display background is not separately screened, and the annotation process is directly executed. After the current annotation operation is completed, if the sharing instruction is received, the hidden instruction is hidden. Menus and other system icons, only retain the background and annotation operation track, and then take a screen shot of the currently displayed content, you can also get a clear annotation picture. The subsequent sharing process of the annotation record picture is the same as the previous description, and will not be separately explained here. In this implementation, only one image processing process can realize the generation of the annotation record picture, and the process is simple.
