In addition, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the aspects may be practiced without these specific details.
The embodiment of the disclosure provides a method for recording dot matrix writing content. The recording method of the dot matrix writing content provided by the embodiment can be executed by a computing device, the computing device can be implemented as software, or implemented as a combination of software and hardware, and the computing device can be integrally arranged in a server, a client and the like.
Referring to fig. 1, a method for recording dot-matrix written content in an embodiment of the present disclosure may include the following steps:
s101, after a user logs in the intelligent terminal, communication connection is established between the intelligent pen and the intelligent terminal through lattice writing of the user.
The intelligent terminal can be various electronic devices with communication functions, such as a notebook, a desktop, a tablet computer, a mobile phone and the like. The intelligent terminal is provided with writing software, and writing traces of the intelligent pen on the writing book can be displayed through the writing software.
The user can log in the intelligent terminal based on the user ID, and after the user logs in, the intelligent pen can establish communication connection with the intelligent terminal in a communication connection mode. The communication connection mode can adopt various communication connection modes, for example, a bluetooth mode can be adopted for communication connection.
S102, acquiring a first page identifier of an identifier on first writing paper by using the intelligent pen, wherein the first page identifier is an identifier preset on the first writing paper, the intelligent book for the intelligent pen to write comprises a plurality of writing pages, and each writing page has a different page identifier.
The intelligent pen writing book comprises a plurality of writing pages, and different marks can be arranged on each writing page for distinguishing each writing page, so that different writing pages can be marked. Therefore, when the intelligent pen writes, the page identification code arranged on the preset position of the writing page can be read through the camera module on the intelligent pen, and the first page identification of the identification on the first writing paper is further obtained. By reading the first page identifier, the identifier of the current writing page can be obtained.
S103, acquiring first operation time of the intelligent pen in writing operation of the intelligent pen on the first page.
In order to record writing tracks of different pages, the time of the first writing operation can be recorded in the process of writing tracks on the first page, so that the first operation time is obtained.
Specifically, after the first page identifier is obtained, whether a pressure sensor at the pen point of the smart pen generates a trigger signal or not may be monitored; after the pressure sensor generates a trigger signal, recording the time for acquiring the trigger signal; taking the time for acquiring the trigger signal as the first operation time
And S104, after the writing operation on the first page is finished through the intelligent pen, adding time information into the coordinate information corresponding to the writing trace on the first page to form final writing information, and sending the writing information to the intelligent terminal, so that the intelligent terminal displays the writing content of the intelligent pen based on the time information.
By adding the time information into the writing trace, the writing trace can be displayed based on the time information in the process of displaying the writing trace at the intelligent end. Thereby improving the efficiency of the trajectory writing.
In the process of executing steps S101-S104, before writing, the user logs in the note-taking software located on a mobile phone, tablet or other intelligent terminal using the user ID. Then, the user opens the intelligent pen, and establishes communication connection (wireless modes such as Bluetooth and wifi or wired modes such as USB) with the intelligent terminal. And the note software acquires the ID of the intelligent pen and stores the ID of the intelligent pen and the ID of the user in a correlation manner.
The intelligent pen obtains time information, and the time information is used as third dimension information of each writing point except for an X coordinate and a Y coordinate. The intelligent pen acquires coordinate information of a pen point on the dot matrix writing book and current writing time information in real time, and transmits the coordinate information and the current writing time information as writing point information to the note software. The note software stores each writing point information in the database (as the original information).
The note software creates a blank record according to the time information of the first writing point, synchronously draws in the software page according to the coordinate information of the subsequent writing point, clicks and stores after the user finishes writing, and the note software stores the blank record as a record. As shown in fig. 4a and 4b below: fig. 4a is an actual writing situation, and fig. 4b is a record generated when the note software synchronously draws. To facilitate user query, the generated log file may be named with the initial word of the written content, as shown in fig. 4 b. The user can see all the record files in the note software, and selects the associated record files for combination. When the software merges a plurality of records, the position factor is considered preferentially, the contents with the same page number are merged together, and if the overlapping phenomenon is found in the merging process, a plurality of pages are generated successively according to time.
In addition, when the written content is stored, the user ID and the intelligent pen ID are correspondingly stored. When the same user writes with different smart pens, the user can filter the content written by the same smart pen ID in the note software.
The invention stores the time information of each writing point, so that the user can search and classify the recorded content according to time.

and S204, sending a writing signal to the intelligent terminal based on the login ID.
According to a specific implementation manner of the embodiment of the present disclosure, before the obtaining of the first page identifier of the identifier on the first writing paper by using the smart pen, the method further includes: time information is set on an intelligent book used for writing by an intelligent pen in advance, so that different pages on the same book have different page identifications.
