Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, a flowchart of a method for presenting a file according to an embodiment of the present invention includes the following steps:
and S101, establishing communication connection between the first terminal and the intelligent pen.
Before a user operates the smart pen to write on the paper dot matrix file, the smart terminal establishes communication connection with the smart pen, including wired connection and wireless connection, preferably, a wireless connection mode is adopted, and the wireless connection mode includes but is not limited to bluetooth, Near Field Communication (NFC), Wireless Local Area Network (WLAN), ZigBee, infrared data association (IrDA) and Wi-Fi direct connection. In practical application, the intelligent pen and the intelligent terminal are in wireless connection in a Bluetooth mode preferentially. When the intelligent terminal is connected with the intelligent pen for the first time, the intelligent terminal starts all Bluetooth devices nearby Bluetooth scanning, scanning results are screened according to preset device types and device names, devices meeting conditions are displayed in a list, and a user selects a device corresponding to the device in the list according to the mac address of the intelligent pen to connect. In view of the fact that there are many bluetooth pairing connection technologies in the prior art, the present invention is not described herein again.
And S102, clicking any position or specific position of the paper dot matrix file through an intelligent pen to obtain file index information.
The paper dot matrix file is formed by printing or printing after dot matrix resources are loaded by an electronic file. The paper dot matrix file in the invention not only contains file content, but also carries file index information, and the file index information is ID used for uniquely positioning the electronic file. As known to those skilled in the art, the dot matrix resource is binary data represented by a dot pattern, and a string of binary data can be obtained by shooting and analyzing the dot pattern on the paper dot matrix file by the smart pen, wherein each bit book of the binary data can be defined according to user requirements. For example, for a dot matrix data block capable of storing 48-bit binary data, 0-7 bits are defined as Y-axis coordinates, 8-15 bits are defined as X-axis coordinates, 16-25 bits are defined as page information, 26-29 bits are defined as categories, 30-41 bits are defined as book numbers, and 42-47 bits are used for parity check, fault-tolerant processing, and the like.
In one embodiment of the invention, the file content and the file index information of the paper dot matrix file are encoded by using the same dot matrix resource. The file index information is carried in each dot matrix data block of the dot matrix resource of the encoded file content (as shown in fig. 6 a), and the file index information can be obtained by clicking any position of the paper dot matrix file by a user. For example, in the above lattice resource, 26-41 bits of data are directly used as file index information, or used as a key value, and the intelligent terminal can query the file index information according to the key value.
In one embodiment of the invention, the file content of the paper dot matrix file is encoded by adopting a first dot matrix resource, the file index information of the paper dot matrix file is encoded by adopting a second dot matrix resource, and the file index information is arranged in a cover of the paper dot matrix file or a peripheral area which does not influence the display of the file content. As shown in fig. 6b, the file index information scanning area is disposed below the contents of the file. In this way, the entire code segment of the lattice coding of the file index information can be used to represent the file index information except for a part of bit segments used for reservation and fault tolerance. Relatively speaking, the method is flexible, can meet various requirements, and is not limited by the size of the dot matrix resource.
And step S103, acquiring a corresponding electronic file according to the file index information and displaying the electronic file.
It can be understood that, a user edits an electronic file in advance by using an intelligent terminal, the electronic file may be in a printable file format such as word, excel, pdf, ppt, jpg, and the like, and the electronic file is uploaded to a cloud disk or a network server after the electronic file is edited, so as to obtain file index information. On one hand, in order to obtain the operation of the user on the paper dot matrix file, the dot matrix resource for positioning needs to be loaded on the electronic file, and on the other hand, in order to obtain the file index information, the dot matrix code carrying the file index information needs to be loaded on the electronic file. Two ways of carrying the document index information to the paper dot matrix document have been set forth above. If the mode of FIG. 6a is adopted, the file index information is carried to the first lattice resource, and the first lattice resource is used for encoding the electronic file; if the method of fig. 6b is adopted, it can be implemented as follows: the method comprises the steps of firstly, acquiring a first dot matrix resource and an electronic file to generate an electronic file of dot matrix codes; secondly, acquiring file index information and a second dot matrix resource to generate a cover or a specific area carrying the file index information; and thirdly, combining the two into a document.
As shown in fig. 2, a flowchart of a method for presenting a file according to a second embodiment of the present invention includes the following steps:
step S201, the first terminal and the intelligent pen are in communication connection.
Step S202, clicking any position or specific position of the paper dot matrix file through the intelligent pen to obtain file index information.
Step S203, acquiring a corresponding electronic file according to the file index information and displaying the electronic file.
Steps S201 to S203 are the same as those in the first embodiment, and are not described herein again.
And step S204, obtaining writing track information of the user on the paper dot matrix file by using the intelligent pen.
Because the code point information is printed on the paper dot matrix file, when the intelligent pen writes, marks and paintings on the paper dot matrix file, the intelligent pen can read the dot matrix graph at the position of the pen point, and the code point graph is subjected to image processing and analysis to obtain the writing track information. The writing track information comprises X coordinate information, Y coordinate information, page number information, type information, book number information and the like of writing points.
And S205, synchronously drawing at the corresponding position of the electronic file according to the writing track information.
In practical application, function buttons, such as color, thickness, and eraser of a pen, can be set on a display interface of an electronic file, so that the content displayed on the electronic file can be richer and more free.
During the process of file demonstration, a user can not only switch page numbers at an electronic file end, but also automatically switch electronic files synchronously by switching paper dot matrix files. The reason is that when the intelligent pen acquires writing track information, the intelligent pen can acquire not only the X coordinate and the Y coordinate of the current writing point, but also page number information, so that the intelligent terminal can switch the electronic file to the page number same as the paper dot matrix file for display according to the writing track information.
As shown in fig. 3, a flowchart of a method for demonstrating a file according to a third embodiment of the present invention includes the following steps:
and S301, establishing communication connection between the first terminal and the intelligent pen.
Step S302, clicking any position or specific position of the paper dot matrix file through the intelligent pen to obtain file index information.
Step S303, acquiring a corresponding electronic file according to the file index information and displaying the electronic file.
Steps S301 to S303 are the same as those in the first embodiment, and are not described herein again.
Step S304, establishing communication connection with at least one second terminal.
In the embodiment of the invention, the first terminal can be a teacher terminal or a conference host terminal, and the second terminal can be a student terminal or a participant terminal. .
Step S305, transmitting the file index information to the second terminal, so that the second terminal obtains a corresponding electronic file according to the file index information for displaying.
Preferably, the first terminal is further configured to send the page number information to the second terminal. This automatically keeps the display of the file consistent with that of the first terminal whenever the second terminal joins the tutorial or conference.
And S306, acquiring writing track information of the user on the paper dot matrix file by using the intelligent pen.
And step S307, synchronously drawing at the corresponding position of the electronic file according to the writing track information.
And step S308, transmitting the writing track information to the second terminal so that the electronic file displayed by the second terminal keeps synchronous with the first terminal.
It should be noted that, a user may also directly operate the electronic file at the intelligent terminal without using a paper dot matrix file, and these operation instructions and operation position information need to be synchronously sent to the second terminal, so that the second terminal and the first terminal keep synchronous.
As shown in fig. 4, a flowchart of a file presentation method according to a fourth embodiment of the present invention includes the following steps:
and S401, establishing communication connection between the first terminal and the intelligent pen.
And S402, clicking any position or specific position of the paper dot matrix file through the intelligent pen to obtain file index information.
And S403, acquiring a corresponding electronic file according to the file index information and displaying the electronic file.
Step S404, establishing communication connection with at least one second terminal.
Step S405, recording the screen content of the electronic file in real time, and sending the recorded screen content of the electronic file to a second terminal.
And step S406, acquiring writing track information of the user on the paper dot matrix file by using the intelligent pen.
And step S407, synchronously drawing at the corresponding position of the electronic file according to the writing track information.
The embodiment of the invention keeps the file contents displayed by the second terminal and the first terminal synchronous in a screen recording mode.
As shown in fig. 5, a flowchart of a method for presenting a file according to a fifth embodiment of the present invention includes the following steps:
step S501, a second terminal establishes communication connection with a first terminal;
step S502, acquiring a corresponding dot matrix electronic file according to the file index information sent by the first terminal for displaying;
step S503, receiving writing track information transmitted by the first terminal;
and step S504, synchronously drawing at the corresponding position of the electronic file according to the writing track information.
