[0159] if the target signature area does not include a signature and is not locked, locking the target signature area and associating the target signature area with device information of the user equipment.

[0160] The implementation method of the signature wall will be described below in combination with specific application scenarios.

[0161] In the following embodiments, the display device is taken as an electronic whiteboard for example.

[0162] Embodiment one: realizing the signature wall through a local area network

[0163] The implementation method of the signature wall comprises:

[0164] 1. The electronic whiteboard is connected to a local area network, and the signature wall software is opened. The electronic whiteboard displays the signature wall canvas of the signature wall software in a first display area. The signature wall software automatically starts a local http network service, obtains the current local area network IP address and local html resource path, and generates a url address (i.e. network address) that can be accessed externally;

[0165] 2. The signature wall software generates a two-dimensional code according to the generated url address, and displays a prompt label in the html webpage. The prompt label prompts the user to connect to the local area network in the same network segment as the display device.

[0166] 3. The electronic whiteboard displays the two-dimensional code in a second display area.

[0167] 4. The user scans the two-dimensional code displayed by the electronic whiteboard through the browser or other APP of the user equipment such as a mobile phone or tablet computer, and loads the html resource of the http network service started by the electronic whiteboard through the url address in the two-dimensional code;

[0168] 5. The user equipment obtains the signature wall canvas of the signature wall software of the electronic whiteboard through the loaded html resource, selects a signature area on the signature wall canvas, generates a locking request comprising the position information of the signature area, and sends the locking request to the signature wall software of the electronic whiteboard;

[0169] 6. The signature wall canvas is divided into multiple signature areas. Each signature area can only be selected and operated by one user at a time. If the user does not sign the area after the operation is completed, the area can be unlocked and made available for the next user to select. The locking process of the signature area is as follows: First, check if the signature area has already been signed. If it has, the locking fails. If not, check if the signature area has already been locked. If it has, the locking fails. If it has not been locked, the signature area is locked and associated with the user's device information (such as MAC address, IMEI, etc.). At the same time, the locking result is synchronized to the user's device. If the locking fails, a prompt is given. If the locking succeeds, the user is prompted to proceed to the next step.

[0170] 7. After the user successfully locks the signature area, the electronic whiteboard can associate user information, such as user avatar, name, mobile phone number, ID card number, job information, etc.; it can also associate the user's third-party application login account, such as employee ID, mobile phone number, nickname, etc., and automatically: query the signature information database to see if the historical signature information corresponding to the user information is stored; if the signature information database stores the historical signature information corresponding to the user information, it retrieves the historical signature information corresponding to the user information and sends it to the user device for selection, thereby omitting the user's signature operation and completing one-click signature. The user device will synchronize the selected historical signature information to the electronic whiteboard.

[0171] Alternatively, after selecting a locked signature area, the user can proceed with the signature operation by writing on the signature wall canvas displayed on the user's device. The signature information includes the electrical information of the handwriting trajectory and the position information of the signature area. The signature information is then synchronized to the electronic whiteboard. Upon receiving the signature information, the electronic whiteboard calls multiple handwriting enhancement algorithms to generate different enhanced handwriting information. After signing their name, the user can obtain images generated by different handwriting enhancement algorithms from the electronic whiteboard through page operations. After obtaining the signature images, the user can select a handwriting information according to their personal preference and then send the selected information to the electronic whiteboard.

[0172] 8. After obtaining the signature information selected by the user, the signature wall software of the electronic whiteboard merges the handwriting information into the locked signature area of ​​the currently displayed signature wall canvas for display, thereby completing the signature process;

[0173] 9. The signature wall canvas can be shared with the signer or other third parties via email, WeChat, QQ, or other means as needed;

[0174] 10. Signature information can be shared to a signature information database based on the signature wall canvas, and analysis reports can be generated through big data processing.

[0175] Option 2: Implement a signature wall via the internet

[0176] 1. An electronic whiteboard connects to the Internet, opens a signature wall software, and the electronic whiteboard displays a signature wall canvas of the signature wall software in a first display area. The signature wall software establishes a long connection (for example, establishes a websocket service) with a remote server, and synchronizes local information to the remote server. The local information includes a local html resource path, which is used to obtain html resources. The html resources contain a path for obtaining the signature wall canvas displayed by the electronic whiteboard. The remote server returns a network address that can be accessed (the network address is bound to the local information);

[0177] 2. The electronic whiteboard generates a corresponding two-dimensional code according to the network address, and displays the two-dimensional code in a second display area. The electronic whiteboard can also display prompt information to prompt a signature user to scan the code to obtain the canvas of the signature wall software through a corresponding software;

[0178] 3. A user scans the two-dimensional code displayed by the electronic whiteboard through a browser or other APP of a user device such as a mobile phone or a tablet computer, accesses the remote service area according to the network address in the two-dimensional code, and obtains the signature wall canvas of the electronic whiteboard bound to the network address;

[0179] 4. The user device obtains the signature wall canvas displayed by the signature wall software of the electronic whiteboard through the remote server, selects a signature area on the signature wall canvas, generates a locking request including position information of the signature area, and sends the locking request to the remote server. The remote server synchronizes the locking request to the signature wall software of the electronic whiteboard through the established long connection.

[0180] 5. The signature wall canvas is divided into multiple signature areas, each of which can be selected and operated by only one user. If the user does not sign the position after the operation is completed, the lock can be released for the next user to select. The locking process of the signature area is as follows: first, check whether the signature area has a signature. If yes, the locking fails. If no, determine whether the signature area has been locked. If yes, the locking fails this time. If no, lock the signature area and associate the user device information (such as MAC address, imei, etc.) of the user, and synchronize the locking result to the user device. If the locking fails, a prompt is given. If the locking succeeds, the user can be prompted to perform the next operation. This step can be completed through the signature wall software of the electronic whiteboard, or through the remote server. If it is completed through the remote server, the remote server does not need to synchronize the locking request to the signature wall software of the electronic whiteboard in the previous step.

[0181] 6. After the user successfully locks the signature area, the electronic whiteboard or remote server can associate it with user information, such as the user's avatar, name, mobile phone number, ID card number, job information, etc.; it can also associate it with the user's third-party application login account, such as employee ID, mobile phone number, nickname, etc., and automatically: query the signature information database to see if the historical signature information corresponding to the user information is stored; if the signature information database stores the historical signature information corresponding to the user information, it retrieves the historical signature information corresponding to the user information and sends it to the user device for selection, thereby omitting the user's signature operation and completing one-click signature. The user device will then synchronize the selected historical signature information to the electronic whiteboard.

[0182] Alternatively, after selecting a locked signature area, the user can proceed with the signature operation by writing on the signature wall canvas displayed on the user's device. This generates signature information, including the electrical information of the handwriting trajectory and the location information of the signature area. The signature information is then synchronized to a remote server or electronic whiteboard (sent via the remote server). Upon receiving the signature information, the remote server or electronic whiteboard invokes multiple handwriting enhancement algorithms to generate different enhanced handwriting information. After signing their name, the user can retrieve images generated by different handwriting enhancement algorithms from the electronic whiteboard through page operations. After obtaining the signature images, the user can select a handwriting information according to their personal preference and then send the selected information to the electronic whiteboard.

[0183] 7. After obtaining the signature information selected by the user, the signature wall software of the electronic whiteboard merges the handwriting information into the locked signature area of ​​the currently displayed signature wall canvas for display, thereby completing the signature process;

[0184] 8. The signature wall canvas can be shared with the signer or other third parties via email, WeChat, QQ, or other means as needed;

[0185] 9. Signature information can be shared to a signature information database based on the signature wall canvas, and analysis reports can be generated through big data processing.
