Description

Technical Field

[0001] This invention relates to the field of e-ink display, and more particularly to a note-generating method, an e-ink device, and a storage medium. Background Technology

[0002] E-ink devices are electronic devices that use electronic ink displays (E-ink). The display effect of E-ink screens is highly similar to that of paper, avoiding the glare problems of traditional LCD displays and providing users with a good visual experience. Therefore, many E-ink devices offer handwriting functionality, allowing users to write on the E-ink screen using a medium (such as an electromagnetic pen) to record notes related to life or work, and also making it easy for users to review those notes. However, existing E-ink devices cannot automatically generate notes based on user handwriting, resulting in a poor user experience. Summary of the Invention

[0003] This invention provides a note-generating method, an e-ink device, and a storage medium, aiming to automatically generate notes based on user handwriting to improve note-generating efficiency.

[0004] In a first aspect, embodiments of the present invention provide a note-generating method applied to an e-ink display device, the method comprising:

[0005] Display a note editing page, which includes a toolbar area and a note editing area, and the toolbar area includes template options;

[0006] When a user's handwriting is detected on the note editing page, the writing position and format type of the handwriting are determined and cached.

[0007] In response to the user's triggering action on the template option, the template selection page is displayed, and the note template selected by the user on the template selection page is obtained;

[0008] The note template is displayed in the note editing area, and each of the written strokes is filled into the note template according to the writing position and format type of each cached written stroke to generate a note.

[0009] Secondly, embodiments of the present invention also provide an e-ink screen device, the e-ink screen device including an e-ink screen, a processor, a memory, a computer program stored in the memory and executable by the processor, and a data bus for realizing connection and communication between the e-ink screen, the processor and the memory, wherein when the computer program is executed by the processor, it implements the note generation method as described in the first aspect.

[0010] Thirdly, embodiments of the present invention also provide a storage medium for computer-readable storage, wherein the storage medium stores one or more programs that can be executed by one or more processors to implement the note generation method as described in the first aspect.

[0011] This invention provides a note-generating method, an e-ink device, and a storage medium. The method detects a user's handwriting on a note-editing page, determines the writing position and format type of the handwriting, and caches this information. Subsequently, after the user selects a note template, the template is displayed in the note-editing area, and each handwriting entry is filled into the template based on its cached position and format type to generate a note. This achieves automatic note generation based on the user's handwriting, significantly improving note-generating efficiency. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0024] It should be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0025] The operating system used by the e-ink device involved in this invention embodiment is a distributed operating system developed based on the OpenHarmony project, designed for all scenarios. The OpenHarmony system provides functions such as distributed soft bus, distributed data management, distributed task scheduling, and a distributed virtualization platform. The distributed soft bus serves as a unified foundation for multiple intelligent devices, providing unified distributed communication capabilities for seamless interconnection between intelligent devices. It can quickly discover and connect intelligent devices, and efficiently transmit tasks and data. Relying on soft bus technology, distributed data management capabilities can be achieved, thereby realizing distributed management of application data and user data. User data is no longer bound to a single physical device; business logic and data storage are separated, and data is seamlessly connected when applications run across devices.

[0026] From a software perspective, operating systems supporting distributed soft bus technology can deploy specific applications on a per-ability basis. An ability is an abstraction of the capabilities an application possesses and is a crucial component of the application. In other words, an application can possess multiple capabilities (i.e., it can contain multiple abilities). Specifically, application capabilities are divided into two types: FA (Feature Ability) and PA (Particle Ability). FA represents capabilities with a UI (User Interface), which are visible to the user and designed for interaction. PA represents capabilities without a UI and primarily provides support for FAs, such as providing computing functionality as a background service or providing data access functionality as a data repository, etc.

[0027] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] Please see Figure 1 , Figure 1 This is a flowchart illustrating a note generation method provided in an embodiment of the present invention.

[0029] like Figure 1 As shown, the note generation method includes steps S101 to S104.

[0030] Step S101: Display the note editing page. The note editing page includes a toolbar area and a note editing area. The toolbar area includes template options.

[0031] For example, such as Figure 2 As shown, the note-editing page includes a toolbar area 10 and a note-editing area 30. Writing is not allowed in the toolbar area 10; users can use a stylus or finger to click. Writing and clicking are also possible in the note-editing area 30 using a stylus or finger. The toolbar area 10 includes options for saving / exiting (11), pen (12), pencil (13), erasing (14), inserting a shape (15), inserting a page (16), deleting this page (17), more options (18), pen thickness (19), and color (21). When a user selects pen option 12 or pencil option 13, the shape of their handwriting will correspond to the pen or pencil shape. Users can also select the thickness and color of their handwriting using pen thickness option 19 and color option 21.

[0032] After tapping the erase option 14 with a stylus or finger, the user can erase the handwriting displayed in the note editing area 30. After tapping the insert shape option 15 with a stylus or finger, the user can select the shape to insert. For example, ... Figure 3 As shown, toolbar area 10 also includes options for a line, a triangle, an ellipse, and a rectangle, allowing users to select the shape to insert as a line, triangle, ellipse, or rectangle. When the user clicks the "Insert Page" option 16 with a stylus or finger, the e-ink device inserts a blank page after the current page. When the user clicks the "Delete Current Page" option 17 with a stylus or finger, the e-ink device deletes the current page (i.e., the currently displayed page).

[0033] After the user taps the more options 18 with a stylus or finger, the toolbar area 11 may also include... Figure 4 The device includes template options 22, refresh option 23, rename option 24, note encryption option 25, and export option 26. After the user taps template option 22 with a stylus or finger, the e-ink device displays a template selection page where the user can choose a note template. Tapping refresh option 23 refreshes the notes in the note editing area 30. Tapping rename option 24 allows the user to rename the notes in the editing area 30. Tapping note encryption option 25 encrypts the notes in the editing area 30. Tapping export option 26 exports the notes in the editing area 30 as a PDF file.

[0034] Understandable Figures 1 to 4 The note editing page shown in the figure is only a part of the interface diagram related to the embodiment of the present invention, and does not constitute a limitation on the note editing page of the embodiment of the present invention. The specific note editing page may include more or fewer options than shown in the figure, or the layout of each option may be inconsistent with that shown in the figure.

[0035] Step S102: When the user's handwriting is detected on the note editing page, determine the writing position and format type of the handwriting, and cache the writing position and format type of the handwriting.

[0036] In this embodiment of the invention, the handwriting is the handwriting formed by a single writing operation. A single writing operation includes a writing drop operation, a writing movement operation, and a writing lift operation. When a writing drop operation is detected (e.g., the touch signal of the stylus is first received), it can be determined that the writing operation has started. When a writing lift operation is detected (e.g., the reception of the touch signal stops and no touch signal is received after a set time), it can be determined that the writing operation is completed.

[0037] The writing position of the handwriting includes the starting position and the ending position of the handwriting in the note editing area. The starting position is the position where the stylus clicks when the writing drop operation is detected in the writing operation corresponding to the handwriting, and the ending position is the position of the stylus when the writing lift operation is detected in the writing operation corresponding to the handwriting.

[0038] For example, when a user writes "Zhang San" with a stylus, the stylus begins to receive touch signals when it touches the e-ink screen, detecting a writing drop operation. The stylus's current position is then determined as the starting point of the writing. The user begins writing "Zhang San Li Si". After writing "Zhang", the user lifts the stylus, thus no touch signal is received. However, if the user continues writing "San" within a set time, it is determined that no writing drop operation was detected. Similarly, if the user lifts the stylus after writing "San", no touch signal is received, and no touch signal is received after the set time, it is determined that a writing drop operation was detected. Therefore, the stylus's position after writing "San" is determined as the ending point of the writing, thus confirming the completion of writing "Zhang San". This is how the handwriting of "Zhang San" is obtained.

[0039] In one embodiment, the format type of handwriting can be determined by converting the handwriting into text data, inputting the text data into a preset format type recognition model, and obtaining the format type of the handwriting. The format type may include date, name, address, mobile phone number, ID card number, and body text, etc., and the format type recognition model is a pre-trained neural network model. The format type recognition model can accurately determine the format type of the handwriting.

[0040] In one embodiment, multiple sample data sets are acquired, and a preset neural network model is iteratively trained until convergence based on these sample data sets. The sample data sets include sample text and the corresponding labeled format types. The training process may include: inputting the sample text from the sample data into the preset neural network model to obtain the predicted format type of the sample text; calculating the model loss value using the cross-entropy loss function based on the labeled format type and the predicted format type; if the model loss value is less than a preset loss value, updating the model parameters of the preset neural network model, and continuing to train the preset neural network model with updated model parameters until the preset neural network model converges, thereby obtaining a format type recognition model.

[0041] The neural network models can include Convolutional Neural Networks (CNN) models, Deep Neural Networks (DNN) models, Recurrent Neural Networks (RNN) models, Factorisation Machine Supported Neural Networks (FNN) models, Neural Factorization Machines (NFM) models, Attentional Factorization Machines (AFM) models, and so on.

[0042] Step S103: In response to the user's trigger operation on the template option, display the template selection page and obtain the note template selected by the user on the template selection page.

[0043] For example, after a user taps the template option with a stylus or finger, the e-ink device displays something like this. Figure 5 The template selection page is shown. Figure 5 As shown, the template selection page includes note templates for blank pages, plans, calendars, grid paper, small squares, large squares, English writing, musical notation, etc., and may also include note templates for meeting minutes, etc. This is understandable. Figure 5 The note template shown is merely exemplary and does not constitute a specific limitation on the note template in the embodiments of the invention.

[0044] Step S104: Display the note template in the note editing area and fill each writing stroke in the note template according to the writing position and format type of each cached writing stroke to generate a note.

[0045] For example, if the user selects a note template corresponding to meeting minutes, and assuming the cache does not contain the handwriting location and format type, then... Figure 6 As shown, the e-ink device displays the note template corresponding to the meeting minutes in the note editing area 30.

[0046] In one embodiment, the manner of filling each writing stroke in the note template according to the writing position and format type of each writing stroke cached may be: determining whether the note template is in the first preset note template set or in the second preset note template set; in the case where the note template is in the first preset note template set, determining the filling position of each writing stroke in the note template according to the writing position of each writing stroke cached; and filling each writing stroke in the note template according to the filling position of each writing stroke in the note template. Wherein, the writing position of the writing stroke includes the writing start position and the writing end position of the writing stroke in the note editing area.

[0047] Wherein, the first preset note template set is different from the second preset note template set, and the first preset note template set includes Figure 5 the note templates corresponding to the cross-grid, the note templates corresponding to the square-grid, the note templates corresponding to the small square grids, the note templates corresponding to the large square grids, etc. in

[0048] For example, as Figure 7 shown, the cached writing strokes include the handwritten stroke 41 "思", the handwritten stroke 42 "考", the handwritten stroke 43 "能", and the handwritten stroke 44 "力", and the note template selected by the user is the note template corresponding to the cross-grid. Since the note template corresponding to the cross-grid is in the first preset note template set, based on the writing positions of the handwritten stroke 41 "思", the handwritten stroke 42 "考", the handwritten stroke 43 "能", and the handwritten stroke 44 "力" in the note editing area 30, the filling positions of the handwritten stroke 41 "思", the handwritten stroke 42 "考", the handwritten stroke 43 "能", and the handwritten stroke 44 "力" in the note template corresponding to the cross-grid can be determined, and then the handwritten stroke 41 "思", the handwritten stroke 42 "考", the handwritten stroke 43 "能", and the handwritten stroke 44 "力" can be filled into the note template corresponding to the cross-grid, so as to obtain the note as Figure 8 shown.

[0049] In one embodiment, in the case where the note template is in the second preset note template set, obtaining the format description information of each to-be-filled area in the note template; determining the to-be-filled area corresponding to each writing stroke according to the format type of each writing stroke cached and the format description information; determining the filling position of each writing stroke in the to-be-filled area corresponding to each writing stroke according to the writing position of each writing stroke; and filling each writing stroke in the note template according to the filling position of each writing stroke. Wherein, the format description information of the to-be-filled area corresponding to the writing stroke matches the format type of the writing stroke, and the format description information includes any one of date, name, address, mobile phone number, ID card, and text, etc.

[0050] In one embodiment, when a user's dragging action on the handwriting in the note-editing page is detected, the position of the dragged handwriting and the positions of the handwriting associated with it are adjusted according to the dragging action. After generating notes using a note template and the user's handwriting, the user can adjust the position of the dragged handwriting and the positions of the handwriting associated with it by dragging it, thereby adjusting the notes to better suit their needs.

[0051] In one embodiment, the toolbar area further includes an image insertion option. After step S104, the method further includes: responding to the user's triggering operation on the image insertion option, displaying an image source display page, which includes multiple image source options; obtaining the image source option selected by the user and displaying the file management page corresponding to the selected image source option; obtaining the image selected by the user based on the file management page and inserting the selected image into the note editing page. The multiple image source options include local image options and at least one external image option. The e-ink device communicates with the external storage device corresponding to the external image option via a distributed soft bus. The operating system of the external storage device corresponding to the external image option is a distributed operating system oriented to all scenarios. After generating a note, the user can insert local images or images from the external storage device into the note without needing to obtain images from the external storage device through a cumbersome process.

[0052] In one embodiment, the toolbar area further includes a note-sharing option. After displaying the note-editing page, the method further includes: responding to a user's triggering operation on the note-sharing control, displaying a sharing device display page, and obtaining the target sharing device selected by the user on the sharing device display page; sending a note-sharing request to the target sharing device, and obtaining the response information returned by the target sharing device based on the note-sharing request; if the response information is a preset response information, sending a note to the target sharing device, and obtaining the shared note sent by the target sharing device; dividing the note-editing area into a first note-editing sub-area and a second note-editing sub-area; displaying the note in the first note-editing sub-area and displaying the shared note in the second note-editing sub-area. The target sharing device is another e-ink device, and the target sharing device and the e-ink device are connected via a distributed soft bus. Through the note-sharing function, users of e-ink devices can share notes, thereby enabling users to better utilize their notes.

[0053] In one embodiment, a first instruction triggered by a user for editing notes or shared notes is obtained, and the notes or shared notes are edited according to the first instruction; a first instruction is sent to a target sharing device so that the target sharing device can edit the notes or shared notes according to the first instruction; or a second editing instruction sent by the target sharing device is obtained, and the notes or shared notes are edited according to the second editing instruction. By using different note editing sub-areas to display the notes on the local device and the shared notes sent by the target sharing device, and by allowing the local user to edit the notes on the local device and the shared notes, as well as the user of the target sharing device, it is convenient for multiple users to edit the notes.

[0054] For example, a first e-ink device sends a first note to a second e-ink device and receives a second note from the second e-ink device; the first e-ink device displays the first note in a first note editing sub-area and the second note in a second note editing sub-area; when the first e-ink device receives a first instruction triggered by the user to edit the first or second note, it edits the first or second note and sends the first instruction back to the second e-ink device, so the second e-ink device edits the first or second note based on the first instruction; the first e-ink device receives a second instruction sent by the second e-ink device and edits the first or second note according to the second instruction. Similarly, the second e-ink device can also implement the same process as the first e-ink device, which will not be elaborated here.

[0055] The note generation method provided in the above embodiments determines the writing position and format type of the handwriting when the user's handwriting is detected on the note editing page, and caches the writing position and format type of the handwriting. Subsequently, after the user selects a note template, the note template is displayed in the note editing area, and each handwriting is filled into the note template according to the cached writing position and format type of each handwriting to generate a note. This realizes the automatic generation of notes based on the user's handwriting, which greatly improves the note generation efficiency.

[0056] Please see Figure 9 , Figure 9 This is a schematic block diagram of the structure of an e-ink screen device provided in an embodiment of the present invention.

[0057] like Figure 9 As shown, the e-ink device 300 includes a processor 301, a memory 302, and an e-ink 303. The processor 301, memory 302, and e-ink 303 are connected via a bus 304, such as an I2C (Inter-integrated Circuit) bus.
