Description

Technical Field

[0001] The present application relates to the field of handwriting input technology, and in particular to a handwriting input method, device, electronic device and storage medium for third-party applications based on an ink screen. Background Art

[0002] Electronic ink screen technology uses electrophoresis technology to display images. The display effect of this type of screen is very close to that of traditional paper, so it is also called "electronic paper". Electronic ink is usually made of a thin film composed of a large number of microcapsules. The microcapsules contain pigment particles with different charges. In the initial state, the pigment particles are suspended in the microcapsules. When an electric field in a certain direction is applied, the corresponding pigment particles are pushed to the top, and the microcapsules will display different colors. Microcapsules of different colors form various texts and patterns.

[0003] As the number of application functions of electronic ink screen devices increases, more and more people install third-party applications on electronic ink screen devices for use. However, due to the technical characteristics of electronic ink screens, when performing handwriting input in third-party applications, it is necessary to generate a handwriting layer above the interface of the third-party application, and then perform handwriting input on the handwriting layer. However, the handwriting layer is generally covered on the interface of the third-party application, and the third-party application cannot be quickly set up during handwriting input. During handwriting input, it is usually necessary to set up the third-party application or set the handwriting input content and the content of the third-party application interface. At this time, it is necessary to exit from the handwriting layer and switch to the interface of the third-party application before the third-party application can be controlled. This will bring inconvenience to handwriting input and reduce the efficiency of handwriting input. Summary of the invention

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood in specific circumstances.

[0061] The handwriting input method provided in the embodiment of the present application can be used for a display device equipped with an ink screen. The display device can be an electronic device such as a tablet computer, a mobile phone, an e-reader, a personal digital assistant (PDA) based on an ink screen. Specifically, the display device may include an ink screen, an image processing module, a microcontroller, a screen driver module, a timing control circuit, and a power control circuit.

[0062] The following is a detailed description of the various embodiments of the present application.

[0063] Figure 1 This is a flowchart of Example 1 of the handwriting input method for a third-party application based on an ink screen provided in the present application. The handwriting input method for a third-party application based on an ink screen provided in the embodiment of the present application can be executed by a handwriting input device for a third-party application based on an ink screen. The handwriting input device for a third-party application based on an ink screen can be implemented in hardware and / or software and integrated in a display device equipped with an ink screen.

[0064] The following description is made by taking the handwriting input method of a third-party application based on an ink screen executed by a handwriting input device based on an ink screen as an example. Figure 1 , the handwriting input method comprises:

[0065] Step S10: In response to a start signal for handwriting input to a third-party application, detecting configuration information of a display interface of the third-party application.

[0066] Among them, the start signal can be a signal triggered by a virtual button, a physical button or a remote control method on the ink screen, or it can be a signal triggered by a virtual button on the display interface of the handwriting layer. In addition, it can be understood that in a handwriting drawing input of a stylus, including a writing drop operation, a writing movement operation and a writing lift operation, when the writing drop operation of the stylus is detected (for example, a start signal to start handwriting drawing for a third-party application), it can be determined that the writing drawing input has entered, and when the writing lift operation of the stylus is detected (for example, an end signal of handwriting drawing for a third-party application), it can be determined that the writing drawing input is completed. In other words, the start signal can also be a writing drop operation of the stylus.

[0067] The handwriting layer is used to continuously collect coordinate information corresponding to the handwriting drawing input when the handwriting drawing input is detected, and the drawing layer is used to display the relevant content of the handwriting drawing.

[0068] When a start signal for handwriting input to a third-party application is received, configuration information of the display interface of the third-party application is obtained, wherein the configuration information of the display interface of the third-party application includes the control name, control type, control coordinate position, control area size and control area shape on the display interface of the third-party application, and the controls include content display controls, tool controls, title controls, menu controls, scroll bars and status controls, etc.

[0069] Step S20: create a handwriting layer above the display interface of the third-party application according to the configuration information of the display interface, wherein the handwriting layer is a transparent layer, and the projection of the handwriting layer in the normal direction of the display interface does not overlap with the non-content area on the display interface of the third-party application.

[0070] Among them, the configuration information of the display interface of the third-party application includes the control name, control type, control coordinate position, control area size and control area shape on the display interface of the third-party application, and the control includes content display control, tool control, title control, menu control, scroll bar and status control. When a handwriting layer is created above the display interface of the third-party application according to the configuration information of the display interface, the projection of the handwriting layer in the normal direction of the display interface does not overlap with the non-content area on the display interface of the third-party application, and the non-content area refers to the other area on the display interface of the third-party application except the area corresponding to the content display control, so the areas corresponding to the tool control, menu control and scroll bar on the display interface of the third-party application are not covered by the handwriting layer, so when handwriting input is performed, the third-party application can be controlled without switching to the display interface of the third-party application. In one embodiment of the present application, the non-content area includes a toolbar, a scroll bar and a status bar.

[0071] Step S30: Acquire the handwritten content inputted on the handwriting layer.

[0072] The handwritten content may include a handwritten drawing trajectory, or may be a symbol or text converted from handwritten drawing information.

[0073] The handwriting layer can generate a corresponding handwriting drawing trajectory in response to the handwriting drawing input. For example, the interactive interface of the handwriting layer displayed on the ink screen provides a handwriting drawing component, wherein the handwriting drawing component is used to receive the data report point of the handwriting drawing input of the stylus, and determine the coordinate information corresponding to the handwriting drawing input. The handwriting layer can determine the handwriting drawing information based on the coordinate information and the default or set handwriting parameters (wherein the handwriting width, handwriting color, handwriting type, etc. of the handwriting trajectory correspond to the handwriting parameters).

[0074] Exemplarily, when a third-party application is running on the ink screen and the third-party application enters the handwriting drawing state, the ink screen detects the handwriting drawing input of the handwriting layer. When the handwriting drawing input is detected, the coordinate information corresponding to the handwriting drawing input is continuously collected, and the handwriting drawing information corresponding to the handwriting drawing input is determined based on the coordinate information collected in real time.

[0075] Step S40: display the handwritten content in the display interface of the third-party application.

[0076] The handwritten content may be combined with the initial display content in the display interface of the third-party application and then displayed in the display interface of the third-party application, or the handwritten content may be converted into text and then added to the display interface of the third-party application for display.

[0077] To summarize, the present application sets the projection of the handwriting layer in the normal direction of the display interface to not overlap with the non-content area on the display interface of the third-party application. Therefore, the handwriting layer will not block the non-content area of ​​the third-party application. When handwriting input is performed, the third-party application can be controlled without switching to the display interface of the third-party application, which can improve the efficiency of handwriting input of third-party applications on the electronic ink screen and the user experience.

[0078] Please refer to Figure 2 , Figure 2 This is a flowchart of step S20 of the first embodiment of the handwriting input method for a third-party application based on an ink screen provided by the present application. Further, in one embodiment of the present application, the step of creating a handwriting layer above the display interface of the third-party application according to the configuration information of the display interface includes:

[0079] Step S201: obtaining a location area of ​​a non-content area on the display interface of the third-party application according to the configuration information of the display interface;

[0080] Step S202: removing the non-content area from the area corresponding to the display interface of the third-party application to obtain a handwriting area;

[0081] Step S203: creating a handwriting layer overlapping the handwriting area above the display interface of the third-party application.

[0082] As can be seen from the above, the configuration information of the display interface of the third-party application includes the control name, control type, control coordinate position, control area size and control area shape on the display interface of the third-party application, and the control includes content display control, tool control, title control, menu control, scroll bar and status control, etc. The present application obtains the position area of ​​the non-content area on the display interface of the third-party application, and the non-content area refers to the other area on the display interface of the third-party application except the area corresponding to the content display control, and then removes the position area of ​​the non-content area from the area corresponding to the display interface of the third-party application to obtain the handwriting area, and finally creates a handwriting layer overlapping with the handwriting area above the display interface of the third-party application.

[0083] Please refer to Figure 3 , Figure 3This is a flow chart of the second embodiment of the handwriting input method for a third-party application based on an ink screen provided by this application. Figure 1 On the basis of the provided handwriting input method, further, before the step of creating a handwriting layer above the display interface of the third-party application according to the configuration information of the display interface, the handwriting layer is a transparent layer, and the projection of the handwriting layer in the normal direction of the display interface does not overlap with the non-content area on the display interface of the third-party application, the handwriting input method also includes:

[0084] Step S12: creating a tool layer above the display interface, wherein the tool layer is provided with virtual function keys and the tool layer is movable.

[0085] The present application is provided with a tool layer, and virtual function keys are provided on the tool layer. The virtual function keys can be used to set handwritten content or handwriting input handwriting or third-party applications, which can improve the interactive convenience of handwriting input on the ink screen. Moreover, the tool layer is movable, so the tool layer can be moved at any time to avoid the tool layer blocking the non-content area on the display interface of the third-party application, thereby ensuring that the third-party application can be freely set. Furthermore, the tool layer can be a transparent layer or an opaque layer. In one embodiment of the present application, the tool layer is preferably a transparent layer, so that the tool layer will not block the third-party application.

[0086] On the basis of the above, further, the virtual function keys include a parameter setting key and an erase key:

[0087] The parameter setting key is used to set the handwriting parameters of the stylus, and the erase key is used to erase the handwriting of the stylus on the ink screen.

[0088] The parameter setting key is used to set the handwriting parameters of the stylus, which are used for the corresponding format when drawing handwriting traces, such as handwriting width, handwriting color, handwriting type (such as marker, pencil, pen, brush, eraser, etc.), etc. The user's usage habits can be met by adjusting the handwriting parameters. The erase key is used to erase the handwriting of the stylus on the ink screen. When the user finds that the handwriting content is wrong or does not meet the requirements after handwriting input, the handwriting can be deleted by clicking the erase key.

[0089] Please refer to Figure 4 , Figure 4 This is a flowchart of step S20 of the second embodiment of the handwriting input method for a third-party application based on an ink screen provided by this application. Figure 3On the basis of the provided handwriting input method, further, the projection of the tool layer in the normal direction of the display interface does not overlap with the non-content area on the display interface of the third-party application, and the projection of the handwriting layer in the normal direction of the display interface does not overlap with the projection of the tool layer in the normal direction of the display interface;

[0090] The step of removing the position area of ​​the non-content area from the area corresponding to the display interface of the third-party application to obtain the handwriting area includes:

[0091] Step S2022: remove the location area of ​​the non-content area and the area corresponding to the tool layer from the area corresponding to the display interface of the third-party application to obtain a handwriting area.

[0092] This application prevents the tool layer from affecting the operation of the non-content area on the display interface of the third-party application and the operation of the handwriting layer by setting the projection of the tool layer in the normal direction of the display interface to not overlap with the non-content area on the display interface of the third-party application, and by setting the projection of the handwriting layer in the normal direction of the display interface to not overlap with the projection of the tool layer in the normal direction of the display interface. Therefore, the handwriting area is obtained by removing the position area of ​​the non-content area and the area corresponding to the tool layer from the area corresponding to the display interface of the third-party application, and the handwriting layer is prevented from covering the tool layer, ensuring that the virtual function keys can be used normally.

[0093] On the basis of the above, further, the tool layer is located above the handwriting layer, and the area of ​​the tool layer is smaller than the area of ​​the handwriting layer. The tool layer is arranged above the handwriting layer, so that the tool layer can be used normally, and the area of ​​the tool layer is smaller than the area of ​​the handwriting layer, and at the same time, it can be ensured that the handwriting layer has a large enough area for the user's handwriting input.

[0094] Please refer to Figure 5 and Figure 6 , Figure 5 This is a flowchart of Embodiment 3 of the handwriting input method for a third-party application based on an ink screen provided in this application. Figure 6 This is a flowchart of step S20 of the third embodiment of the handwriting input method for a third-party application based on an ink screen provided by this application. Figure 1On the basis of the provided handwriting input method, further, in an embodiment of the present application, before the step of creating a handwriting layer above the display interface of the third-party application according to the configuration information of the display interface, the handwriting layer is a transparent layer, and the projection of the handwriting layer in the normal direction of the display interface does not overlap with the non-content area on the display interface of the third-party application, the handwriting input method also includes:

[0095] Step S14: obtaining a location area of ​​the content protection zone of the ink screen according to the configuration information of the display interface;

[0096] The step of removing the position area of ​​the non-content area from the area corresponding to the display interface of the third-party application to obtain the handwriting area includes:

[0097] Step S2024: Remove the position area of ​​the non-content area and the position area of ​​the content protection area from the area corresponding to the display interface of the third-party application to obtain a handwriting area.

[0098] The content protection zone may include a floating ball, a floating window, and an area on the ink screen where the content cannot be captured or changed. Therefore, the present application removes the location area of ​​the non-content area and the location area of ​​the content protection zone from the area corresponding to the display interface of the third-party application to obtain a handwriting area, thereby preventing the content of the content protection zone from being blocked, thereby making the display interface of the ink screen of the present application have a better user experience.

[0099] Please refer to Figure 7 , Figure 7 This is a flowchart of the fourth embodiment of the handwriting input method for a third-party application based on an ink screen provided by this application. Figure 3 On the basis of the provided handwriting input method, further, in an embodiment of the present application, after the step of obtaining the handwriting content handwritten input on the handwriting layer, the handwriting input method further includes:

[0100] Step S32: merging the handwritten content and the display content of the display interface of the third-party application into a record file for storage;

[0101] The virtual function keys include a record viewing key, and the record file is viewed by clicking the record viewing key.

[0102] In the present application, the handwritten content and the display content of the display interface of the third-party application are combined to form a record file for storage, so that the user can select and display the historical handwritten content in the record file. Specifically, the user only needs to click the record view button to view the record file, and then select the historical handwritten content to be displayed in the record file. For example, when the user is still dissatisfied with the current handwritten content after multiple handwriting inputs, or feels that the previous historical handwritten content is more appropriate, the user can click the record view button to browse the historical handwritten content of the record file, and then select the appropriate historical handwritten content to display on the display interface of the third-party application, thereby improving the interactive experience of the ink screen.

[0103] Please refer to Figure 8 , Figure 8 This is a flowchart of step S30 of the first embodiment of the handwriting input method for a third-party application based on an ink screen provided by the present application. Further, in the first embodiment of the present application, the step of obtaining the handwriting content inputted by handwriting on the handwriting layer includes:

[0104] Step S301, obtaining a data report point of handwriting input on the handwriting layer;

[0105] Step S302: determine whether the data point is a data point input by a stylus pen, and if so, convert the data point into handwritten content.

[0106] The existing ink screen can receive handwriting input information from fingers and handwriting input information from a stylus. In actual use, in order to avoid the handwriting input information being mistakenly generated by the finger touching the handwriting layer of the ink screen, the present application obtains the data report point of the handwriting input on the handwriting layer, and then determines whether the data report point belongs to the data report point of the stylus input. If so, the data report point is converted into handwriting content. If the data report point does not belong to the data report point of the stylus input, the data report point is not converted into handwriting content, thereby intercepting the input information generated by the finger touching the handwriting layer.

[0107] Please refer to Fig. 9 , Fig. 9 This is a flowchart of step S30 of embodiment 2 of the handwriting input method for a third-party application based on an ink screen provided by the present application. Further, in an embodiment of the present application, the step of obtaining the handwriting content of the handwriting input on the handwriting layer includes:

[0108] Step S303, obtaining the data report point of the handwriting input on the handwriting layer;

[0109] Step S304, determining whether the data report point is a data report point input by a stylus pen, and if the data report point is a data report point input by a stylus pen, converting the data report point into handwritten content;

[0110] When the data reporting point does not belong to the data reporting point input by the stylus, it is determined whether the data reporting point belongs to the preset information, and if so, the third-party application is operated according to the data reporting point.

[0111] The existing ink screen can receive handwriting input information from fingers and handwriting input information from a stylus. In actual use, in order to avoid the handwriting input information being mistakenly generated by the finger touching the handwriting layer of the ink screen, the present application obtains the data report point of the handwriting input on the handwriting layer, and then determines whether the data report point belongs to the data report point of the stylus input. If the data report point belongs to the data report point of the stylus input, the data report point is converted into handwritten content; if the data report point does not belong to the data report point of the stylus input, it is determined whether the data report point belongs to preset information. If so, the third-party application is operated according to the data report point. The present application operates the third-party application with the data report point of the finger handwriting input that belongs to the preset information, thereby intercepting the data report point of the finger handwriting input that does not belong to the preset information, thereby further improving the convenience of using the ink screen during handwriting input.

[0112] For example, the preset information may be a data point when two fingers move in opposite directions, a data point when two fingers move toward each other, etc. When the preset information is a data point when two fingers move in opposite directions, the display interface of the third-party application is zoomed in according to the data point; when the preset information is a data point when two fingers move toward each other, the display interface of the third-party application is zoomed out according to the data point. For example, the preset information may be a data point when a finger slides to the left, a data point when a finger slides to the right, etc. When the preset information is a data point when a finger slides to the left, the display interface of the third-party application is switched to the next page according to the data point; when the preset information is a data point when a finger slides to the right, the display interface of the third-party application is switched to the previous page according to the data point.
