Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, 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.
Fig. 1 is a schematic flow chart of a method for sharing handwriting writing content according to an embodiment of the present invention. The execution subject of the method can be a terminal, a server and other devices with an operation function. The first terminal and the second terminal are two carriers capable of receiving shared handwriting writing contents mutually. As shown in fig. 1, the icon processing method for a dot matrix page includes:
110, when the first terminal is connected with the writing acquisition device, the first terminal receives handwriting information which is sent by the writing acquisition device and is written on a book with lattice resources; the handwriting information includes pen tip trajectory coordinates, a timestamp for each pen tip trajectory coordinate, and a page ID for the lattice resource.
The writing acquisition device can be a dot matrix digital pen. The dot matrix digital pen is a dot matrix digital pen with a dot matrix identification function, which is called a digital pen for short, and a pressure sensor, a processor, a camera, a memory, a communication module and the like are arranged in the digital pen. Similarly, the coordinate unit output by the dot matrix digital pen is AU.
After the pressure sensor receives the pressure signal, the camera is started, the camera is a high-speed camera, the dot matrix through which the pen point passes can be photographed at the speed of about 100 sheets per second, the X and Y coordinate values of the pen point in the writing process are recorded, and the position coordinate of each pen point is obtained, so that the accurate acquisition of the handwriting is realized. The processor will record a time stamp of the pen tip movement, the writing sequence and writing speed of each stroke point. Meanwhile, a pressure sensor arranged in the dot matrix digital pen can record the pressing force of a pen point to obtain pressure-sensitive data, and the pressure-sensitive data can be converted into the weight and thickness of the written strokes to be displayed in the subsequent process. Namely: acquiring and recording the writing structure and the stroke accurate position of the Chinese character based on micron-sized X and Y coordinates; acquiring and recording stroke sequence and speed of Chinese character writing based on coordinate points of the timestamp; and acquiring and recording the weight and thickness of the Chinese character stroke writing based on the pen point pressure sensor to obtain pressure sensing data. These position coordinates, pressure-sensitive data, velocity information, and the like are collectively referred to as dot matrix data.
The data is sent to the terminal through the data interface in two modes, one mode is real-time sending, a processor arranged in the dot matrix digital pen codes dot matrix data into a standard transmission data packet in real time, a Media Access Control (MAC) address of the dot matrix digital pen is added to a packet header of the standard transmission data packet, and then the data interface transmits the transmission data packet to the terminal in real time through a wired or wireless mode.
The other is non-real time transmission, the processor encodes the dot matrix data into a standard transmission data packet in real time, adds the MAC address of the dot matrix digital pen to the packet head of the data packet, then stores the data packet in the memory, and transmits the transmission data packet stored in the memory to the terminal equipment by the data interface at the set time or when the writing acquisition device and the terminal establish connection or other non-real time modes. The data interface is a wired data interface or a wireless data interface; the wired data interface is a Universal Serial Bus (USB) interface, a MiniUSB interface, a MicroUSB interface, a parallel port and a Serial port; the wireless data interface is a Bluetooth interface, an infrared interface, a Wifi interface, a 2.4-5.0GHz band interface or a wireless communication interface.
Specifically, the dot matrix digital pen writes on a book with dot matrix resource codes and collects dot matrix data, and the dot matrix data have time stamps.
The handwriting information further includes a user ID, and step 110 further includes:
the first terminal inquires whether records of a plurality of books of the same type exist under the user ID according to the user ID; when present, displaying a plurality of books of the same type; receiving second selection operation information aiming at a plurality of books sent by a user terminal; and determining a target book according to the second selection operation information, and acquiring handwriting information which is sent by the writing acquisition device and is written in the target book.
The book comprises two types, one type is that a plurality of books have the same lattice resource codes, for example, the book belongs to one type, for example, the G1 intelligent book has a plurality of book records, for example, a Chinese work book and a math work book, and lattice addresses are the same. When the writing acquisition device acquires in real time or acquires offline, the book needs to be selected so as to determine a target book from the plurality of books for synchronization. When the user is in real-time writing or offline synchronization, whether a plurality of notebook records of the same type exist in the user account is checked, if yes, an option box is popped up, a plurality of currently available notebooks of the type corresponding to the dot matrix are listed, and if one notebook is selected manually by the user, all handwriting information enters the designated notebook of the type.
Specifically, the target book may be determined by selecting a state of the book, and by way of example and not limitation, the book has two states, namely a current valid state and a historical filing state, and the current valid state is set for the book that has been completed and is no longer subjected to handwriting writing, and the current valid state is set for the book that can also be subjected to handwriting writing, and the book in the current valid state is the target book. If a plurality of books of the current effective state exist, one of the books of the current effective state can be determined as the target book through selection. For example, the G1 smartbook has a plurality of records, such as the 2019 language work notebook, the 2020 language work notebook, and the notebook that has completed or is not receiving handwriting, such as the 2019 language work notebook, may be set as "filing", and then the currently effective notebook is the 2020 language work notebook receiving handwriting. The archived book can be viewed and browsed, and if handwriting needs to be received again, the state of the book needs to be modified, namely the state of the book is modified into a current valid state.
Therefore, before the present application, the method may further include: the book ID and the user ID are bound, so that one or more books can exist under the user ID, and when a certain book is clicked by the writing acquisition device, the handwriting information of the writing acquisition device on the book can be synchronized to the book corresponding to the user ID. The book ID may be represented by a dot matrix resource code of a certain area on the book, for example, a writing acquisition device clicks a preset area on the book, so that after the clicked dot matrix coordinate is sent to a terminal or a server, the terminal or the server may acquire the book ID, determine a user ID corresponding to the book ID, and synchronize handwriting information written by the writing acquisition device into the book corresponding to the user ID.
The other type of the notebook is that a plurality of books have different lattice resource codes, each page of each book has different lattice resource codes, and when the writing acquisition device writes on different pages, because the lattice resource codes of each page are different, the lattice coordinates of pen points in the handwriting information acquired by the writing acquisition device are also different, so that different pages can be determined through different lattice coordinates, and the automatic skipping of the pages is realized.
The following describes the lattice resource page of this document in detail.
The lattice resource page comprises a plurality of lattices, and the lattices are composed of a plurality of very fine points which are regularly arranged according to a special algorithm. The dot matrix is used for providing coordinate parameter information for the writing acquisition device, and the certificate-preserving writing acquisition device can accurately record written handwriting when writing.
An Anoto lattice principle is taken as an example, and the lattice principle is as follows: the size of the dot matrix resource page takes the upper left corner as the origin of coordinates, and the unit is AU, 1AU =0.3/8mm (millimeter), and for a standard A4PDF electronic auxiliary paper file (width =210mm, height =297mm), the size of the corresponding dot matrix resource page can be found as follows: width =210/0.3 × 8=5600AU, height =297/0.3 × 8=7920 AU. Every 6 × 6=36 dots, a minimum data unit is formed. The area was 1.8mm =3.24 square millimeters. 36 dots are distributed, each dot has a diameter of 0.050mm (50 μm) and a dot pitch of 0.300mm (300 μm), and each dot can have 4 different offset positions, up, down, left and right. There are 4 36 square arrangement modes for 36 points, namely 47 trillion arrangement modes, namely one dot matrix can represent any number between 0 and 47 trillion. The total area of 47 trillion 6X6 lattices covered almost the entire continental europe, and the absolute coordinates of any point did not overlap.
The page of the lattice resource has a page ID, and the page ID has two expression forms of a character string type or a numerical value type. The dot matrix data also comprises a page ID, so that after the terminal obtains the dot matrix data sent by the writing acquisition device, the terminal can be positioned to the specific position of the specific page of the specific book according to the dot matrix data.
The character string type, such as 1536.323.0.90, is similar to the representation method of the IP address, and the number of each part represents that: region, bookshelf, book, page.
The value type, such as 168884986023936.
The two representations of the page IDs of the lattice resource can be converted into each other, and it should be noted that the page IDs of the lattice resource are not continuous values, and the number of the resource pages existing between the two page IDs needs to be determined by a specific function.
The page ID of the lattice resource and the lattice data have a corresponding relationship, for example, the position coordinates in the lattice data are associated, and the page ID of the lattice resource may be hidden in the position coordinates.
And 120, the first terminal receives the processed handwriting information which is sent by the writing acquisition device and is obtained according to the first selection operation information.
The first selection operation may be a selection operation on a book, including but not limited to selecting a color of the handwriting, selecting a thickness of the handwriting, selecting a style of the handwriting, and the like. When the processed handwriting information is obtained, the writing acquisition device can record the time stamp of the processed handwriting information.
Wherein, step 120 specifically includes: firstly, a writing acquisition device receives selection information, wherein the selection information comprises at least one of color selection information, stroke weight selection information, style selection information and position selection information; secondly, the writing acquisition device updates at least one of the color, the stroke thickness, the style and the position of the handwriting information according to the color selection information, the stroke thickness selection information, the style selection information and the position selection information; thirdly, the writing acquisition device sends at least one of the color, the stroke thickness, the style and the position of the updated handwriting updating information to the first terminal; and finally, the first terminal receives at least one of the color, the stroke thickness, the style and the position of the updated handwriting-updating information sent by the writing acquisition device.
Specifically, some areas may be preset on the lattice resource page on this document, where the areas have attribute values, and the attribute values may include a number, a position x, a position y, a width w, a height h, a sequence 1, a field name, an extension, and the like.
The item number is a serial number of the region, for example, 6 regions are provided on the lattice page ID, and the number is sequentially numbered, and the number is associated with the page ID of the lattice resource, for example, the page ID of the lattice resource is izform-18122, the lattice page ID of the first region is izform-1812201, and the lattice page ID of the first region is obtained by expanding on the basis of the page ID of the lattice resource, that is, "01" is added after the page ID of the lattice resource, and the lattice page ID of the region "izform-1812201" is generated.
The position x and the position y can be embodied by lattice coordinates. The width w and the height h can be embodied by specific numerical values, so that the specific positions of the areas in the lattice resource page can be described by the position x, the position y, the width w and the height h.
The field name may be a name of the area, and the name may be set according to the use of the area, for example, but not limited to, for example, if a certain area is provided with recording start and stop selection information, the field name may be a recording key.
The expansion item may be an associated service, for example, if the area is provided with an icon, the expansion item may be the names of check boxes within the icon and the position coordinates of each check box. For example, recording start and stop selection information is set in a certain area, one check box in the recording start selection information may correspond to a recording start key, and another check box in the recording stop selection information may correspond to a recording stop key.
The attribute values may be stored in the form of a table in which the number, position x, position y, height h, width w, field name, extension, and the like are stored. The writing acquisition device can send the form to a terminal or a server, the terminal or the server can inquire according to the acquired handwriting information of the pen point, and the relation between the handwriting information of the pen point and the position x, the position y, the width w and the height h in the attribute value is inquired, so that whether the handwriting information of the pen point is in the attribute value is determined. When the handwriting information of the pen point is in the attribute value, corresponding operation can be performed according to the content of the extension item.
The area may include two types of areas, the first being an area where control function key icons are defined, and the second being an area where a range of positions is customized. For the first area, the user-defined control function key icons include, but are not limited to, handwriting color selection icons, handwriting thickness switching icons, recording start and stop icons. In each icon, at least one piece of selection information is corresponded, for example, two colors of red and black are selected under the handwriting color selection icon, each selectable color can be arranged in a color selection frame in the icon, when the color selection frame is clicked through a pen point of the writing acquisition device, confirmation information can be generated, and the confirmation information comprises dot matrix coordinates of the selected color, so that the color switching during the writing of the writing acquisition device is realized. Therefore, the terminal displays the handwriting information in the same color on the display interface of the terminal through the query table.
For the second type of zone, the zone may be associated with a multimedia file, such as an audio file, a video file, or an audio-visual file.
Two types of zones are described in detail below.
Specifically, when the area has an associated icon, corresponding function control may be performed according to the icon. When the icon has the configured selection information, receiving confirmation information of the writing acquisition device aiming at the selection information; processing the handwriting information according to the confirmation information; or starting or stopping the collection of the audio information according to the confirmation information.
The selection information comprises color selection information, handwriting thickness selection information, recording start and stop selection information and collection selection information. Namely, whether the icon is a handwriting color selection icon, a handwriting thickness switching icon, a recording start and stop icon and a collection icon is judged.
When the writing acquisition device selects on the icon, the writing acquisition device can generate confirmation information, the confirmation information can comprise lattice data during confirmation, the lattice data during confirmation is compared with the attribute value of the icon, and therefore the writing acquisition device can confirm specific content corresponding to the confirmation information, such as corresponding specific color and specific handwriting thickness, the handwriting information is displayed on the terminal according to the color or the handwriting thickness corresponding to the confirmation information, and therefore the writing acquisition device realizes selection of the writing color, the handwriting thickness and the like of the writing content.
The recording start and stop icon is that after the writing acquisition device clicks the icon on the notebook to show that the recording is started, the writing acquisition device can acquire the audio information of the user session, and after the recording is stopped, the recording start and stop icon acquires the audio information of the user session.
Specifically, the writing acquisition device acquires the audio information of the user when a recording key of the writing acquisition device is triggered; or the writing acquisition device compares the pen point track coordinate with a preset attribute value, and when the pen point track coordinate is in the attribute value, the writing acquisition device starts audio recording according to the expansion item of the attribute value to acquire the audio information of the user.
The method comprises the steps that a first terminal receives audio information of a user session sent by a writing acquisition device, wherein the audio information comprises a time stamp of the audio information and an MAC address of the writing acquisition device; and the first terminal displays the handwriting information and plays the audio information according to the time sequence according to the MAC address of the writing acquisition device, the time stamp of the coordinate of each pen point track and the time stamp of the audio information. Therefore, the audio information of the user is collected while the writing content of the written handwriting is recorded.
For the second type of area, when the writing acquisition device clicks on the book, if the clicked area is of the second type, the audio file corresponding to the area is played. Therefore, the writing acquisition device can be used for reading, it can be understood that a writing area can be further arranged behind the area and used for writing answers corresponding to the audio files, and therefore the terminal or the server can receive writing information sent by the writing acquisition device and written in the writing area and score the writing information according to the read audio files and the writing information, and the purpose of intelligently evaluating the writing information of the user according to the read contents is achieved.
And step 130, the first terminal processes the handwriting information corresponding to the page ID and/or the processed handwriting information according to the processed handwriting information and the page ID of the lattice resource to obtain page information with multimedia information.
And adding pictures or background lines of the book to the page where the handwriting information is located by the first terminal. And at the same time, the time stamp of the page information with the multimedia information is recorded. The added pictures support zooming, position shifting, rotation and front-back position setting of the layers. The notebook on the terminal has the same background, such as a horizontal line grid or a Chinese character grid, and after receiving the handwriting information, the terminal superimposes the handwriting information on the background of the notebook. If background lines are added to a certain page of the book, the lines are covered on the original book background or the background is replaced, and at the moment, the handwriting information and/or the processed handwriting information are/is superposed on the line background, so that the personalized presentation effect of the page is realized.
In step 140, the first terminal processes the page information with the multimedia information to generate link information corresponding to the page information.
Specifically, the generated link information can be checked based on a webpage end, all handwriting on the page can be played back, if audio information exists, the audio information is played synchronously, the picture and the shading inserted into the page are also shared, and when the handwriting information and/or the processed handwriting information is displayed according to the time stamp, if the audio information exists, the audio information is played according to the time stamp of the audio information. Here, the picture and/or the shading of the page may be displayed according to the time stamp of the inserted picture or the shading, or may be directly displayed on the page of the book of the inserted picture and/or the shading according to the time stamp of the handwriting information and the time stamp of the audio information.
And 150, the first terminal sends the link information to the second terminal so that the second terminal displays the page information through the link information.
