[0071] The technical solutions of the embodiments of this application are described below with reference to the accompanying drawings and related embodiments. In the description of the embodiments of this application, unless otherwise specified or logically conflicting, the terminology and / or descriptions between different embodiments are consistent and can be mutually referenced. Technical features in different embodiments can be combined to form new embodiments based on their inherent logical relationships. In the embodiments of this application, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" describes the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone, where A and B can be singular or plural. In the textual description of the embodiments of this application, the character " / " generally indicates that the preceding and following related objects are in an "or" relationship; for example, A / B can represent A or B. In this application, "first," "second," and various numerical designations are only for ease of description and are not used to limit the scope of the embodiments of this application. For example, they are used to distinguish different messages, rather than to describe a specific order or sequence.

[0072] The widespread use of handwriting recognition technology has provided users with a more flexible and personalized input experience. However, the existing methods for enabling handwriting recognition are often cumbersome and complex, requiring users to go through multiple steps before they can activate the function and perform handwriting operations.

[0073] In one example, let's assume the electronic device is a tablet computer; see [link to relevant documentation]. Figure 1 On the tablet's desktop 100, multiple pre-installed applications (apps) can be displayed, including a clock app, calendar app, gallery app, memo app 110, smart living app, settings app, file management app, email app, music app, calculator app, voice recorder app, app store app, video playback app, fitness and health app, weather app, browser app, etc. Of course, in... Figure 1 The tablet computer shown may also have other apps pre-installed, such as map apps, but this application does not limit this.

[0074] Assuming that the user wants to record some learning notes using the memo APP 110, the user can touch the application icon corresponding to the memo APP 110 on the desktop 100 of the tablet computer shown in the foregoing Figure 1 to select and start the memo APP 110. After the memo APP 110 is started, the memo APP 110 can display a display interface 200 as shown in the foregoing Figure 2 The display interface 200 shown in the foregoing Figure 2 may include a drop-down list option 210, a search option 220, a memo content 230, and an add button 240. The drop-down list option 210 can be provided with a plurality of different classification options for classifying and arranging the content recorded by the user in the memo. The search option 220 can be used by the user to quickly find the content recorded in the memo. The memo content 230 can be used to directly display the recorded content. The add button 240 can be used to add new memo content.

[0075] In an example, the user can operate the add button 240, so that the tablet computer can display a display interface 300 as shown in the foregoing Figure 3 in response to the operation of the user on the add button 240. The display interface 300 shown in the foregoing Figure 3 may include a toolbar 310, which can include a handwriting icon 311, a font style button 312, a task completion marking button 313, a picture adding button 314, a voice input button 315, and a more button 316.

[0076] Before the user creates new learning notes, the user needs to first touch the handwriting icon 311 in the toolbar 310, so that the tablet computer can display a display interface 400 as shown in the foregoing Figure 4 in response to the operation of the user on the handwriting icon 311. The display interface 400 can include a handwriting tool panel 410 and a content display interface 420. The handwriting tool panel 410 can include a control 411 for returning to the display interface 300, a color selection control 412, a brush selection control 413, an eraser tool 414, a picture adding control 415, a voice input control 416, and a setting control 417.

[0077] Then, the user can operate the brush selection control 413 in the handwriting tool panel 410 to display a brush selection toolbar 4131, which can display brushes of different thicknesses. The user can determine the required brush from the brush selection toolbar 4131 or directly use the default brush.

[0078] Assuming that the user directly uses the default brush, the tablet computer can select the default brush in response to the operation of the brush selection control 413 and displayFigure 5 As shown in the display interface 500, the user can write on the display screen of the tablet computer by using a stylus or a finger. Correspondingly, the tablet computer can display the writing content in a style corresponding to the default brush in response to the writing operation.

[0079] Based on the above example, although the user can enter the display interface 400 by operating the handwriting icon 311 in the prior art, then determine the corresponding brush from the brush selection toolbar 4131 by operating the brush selection button 413 in the handwriting tool panel 410, and then write in the display interface 500. Figure 5 However, such a long interaction operation path consumes a lot of time, increases the time cost of the user using the handwriting function, and such a multi-step operation process can also cause user confusion due to the complex operation path, and cause inconvenience in use, which greatly reduces the user's satisfaction with the handwriting function and the overall operation experience. In addition, such a time-consuming and long operation process can also increase the user's cognitive burden, which can cause the user to miss important information in a situation where quick recording or annotation is required, thereby reducing the use efficiency of the handwriting function.

[0080] Therefore, to solve the above problems, the present application provides a writing function starting method and device, electronic equipment and storage medium. After receiving the writing preparation operation of the stylus that meets the first condition in the writing interface, the handwriting function can be directly started. There is no need to select the handwriting icon in the writing interface, then operate the brush selection control in the handwriting tool panel, and then select the brush in the brush selection toolbar. This effectively avoids the situation that the handwriting function needs to be started through a long operation step, optimizes the starting process of the handwriting function, simplifies the operation steps, improves the writing operation efficiency and writing fluency, and improves the user experience.

[0081] The handwriting function starting method provided by the embodiments of the present application can be applied to electronic equipment. The electronic equipment can include a display screen, which can also be referred to as a touch screen, for receiving user operations on the display screen by a finger or a stylus to control the electronic equipment.

[0123] As shown in FIG. 7, the electronic device can further include a hand writing pen 700. Figure 7 A structure schematic diagram of the hand writing pen provided by the embodiment of the present application is shown in FIG. 7. Referring to FIG. 7, the hand writing pen can also be called a touch pen. The hand writing pen can include a processor 710 and a sensing module 720. Figure 7

[0124] It can be understood that the structure shown in the embodiment of the present application does not constitute a specific limitation on the hand writing pen. In other embodiments, the hand writing pen can include more or fewer components than shown in the figure, or combine certain components, or split certain components, or different component arrangements. The components shown in the figure can be implemented in hardware, software or a combination of software and hardware.

[0125] The processor 710 can be provided with a memory for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory can save instructions or data that the processor 110 has just used or repeatedly uses. If the processor 110 needs to use the instructions or data again, it can be directly called from the memory. This avoids repeated access and reduces the waiting time of the processor 110, thereby improving the efficiency of the system.

[0126] The sensing module 720 can be built-in in the hand writing pen, and can be used to send a recognition signal, so that the electronic device (such as a mobile phone) can recognize or judge the state (such as position or posture) of the hand writing pen according to the recognition signal.

[0127] ​Optionally, the induction module 720 can further include an electromagnetic transmitter. The electromagnetic transmitter can be built in the stylus, and can be used to transmit electromagnetic wave signals. When the stylus is within a preset distance (e.g., 12 mm) from the screen of the electronic device, the electromagnetic transmitter can transmit electromagnetic wave signals of a specific frequency, so that the electronic device can identify the three-dimensional position of the stylus, and provide corresponding functions accordingly.

[0128] Optionally, the induction module 720 can further include a Hall sensor. The Hall sensor can be provided in the stylus and the electronic device, and can be used to detect the approach and adsorption state of the stylus. When the stylus approaches the electronic device, the Hall sensor can detect the change of the magnetic field, so as to trigger the corresponding operation of the electronic device, such as displaying a writing interface, so that the electronic device can receive the operation information input by the stylus in the writing interface.

[0129] Optionally, as an implementation manner, the stylus can further include a communication module 730, which can be used to support the communication between the stylus and the electronic device (e.g., a tablet computer).

[0130] Optionally, as an implementation manner, the stylus can further include a sensor module 740, which can be used to assist the electronic device to identify and determine the state or position of the stylus, so as to effectively identify the writing intention of the user (including writing, drawing, signing, etc.). The sensor module 740 can be provided with at least one sensor, such as an acceleration sensor or a gyroscope, etc.

[0131] Optionally, as an implementation manner, the stylus can further include a display module 750, which can be used to support the display function of the stylus.

[0132] As shown in FIG. 8, a flowchart of a handwriting function starting method 800 provided by an embodiment of the present application is shown. The handwriting function starting method 800 can be executed by an electronic device. The electronic device can establish a communication connection with a stylus. The handwriting function starting method 800 can include the following steps: Figure 8 Figure 8 In step 801, the electronic device displays a writing interface.

[0133] In step 801, the electronic device displays a writing interface.

[0134] It should be understood that the writing interface is used to receive the handwriting information input by the user, and can include any interface (or page) in a writing application or other application. For example, the writing application can be the writing application described above. Figure 1 ​The writing interface can be a memo APP 110, a note APP, a drawing APP, or a sketch APP, etc. as shown in the examples; or any APP that allows a user to input handwriting information by handwriting, where the handwriting information can include text and / or images.

[0135] It is understandable that the writing interface is usually used for writing and drawing, and can have handwriting capability and / or be adapted to specific handwriting tools (e.g. a handwriting pen, etc.).

[0136] In the embodiments of the present application, the writing interface can be Figure 3 the display interface 300 as shown in the examples; or the display interface 400 as shown in the foregoing Figure 4 the display interface 400 as shown in the foregoing Figure 5 the display interface 500 as shown in the foregoing.

[0137] In some embodiments, the writing interface can be displayed on the desktop of the electronic device in a full-screen display, a floating display, or a half-screen display, etc.

[0138] In some embodiments, the electronic device can display the writing interface in response to a triggering operation on the writing application.

[0139] It should be understood that the triggering operation can be any operation for displaying the writing interface. The triggering operation can specifically include, but is not limited to, clicking, touching, single-clicking, double-clicking, double-finger sliding, or long-pressing any control or application icon for a preset time length, etc.

[0140] In this embodiment, the triggering operation on the writing application can be one or more operations. For example, in the case where the first application is a note APP, the user can operate the application icon corresponding to the note APP to select and start the note APP, and after the note APP is started, the writing interface can be directly displayed. Based on this, the triggering operation is the operation of the user operating the application icon corresponding to the note APP. For another example, in the case where the first application is a memo APP, based on the foregoing examples, the triggering operation can include touching the application icon corresponding to the memo APP 110 and the operation of the user touching the new button 240, etc.

[0141] In some embodiments, the electronic device can also display the writing interface in response to a triggering operation on the first control.

[0142] For example, the first control can be a control for quickly starting the writing interface, which can be displayed as a desktop icon on the desktop of the electronic device or as a corner mark of the application icon of the writing application, etc.

[0143] In other embodiments, the electronic device can also display the writing interface in response to a triggering operation on the first service, where the first service can be any system service provided by the operating system, such as a voice assistant, etc.

[0144] Based on the above several possible embodiments, it is not difficult to understand that the triggering operation is used to trigger any control, application icon or service, so that the electronic device can perform the corresponding function in response to the above triggering operation. Therefore, in actual design, the specific operation of triggering any control, application icon or service can also be one or more of key input, gesture recognition, body language recognition, speech recognition, expression recognition, eye movement recognition, and face recognition. The present application does not make specific limitations here.

[0145] At step 802, if the electronic device determines that the stylus is hovering above the display screen of the electronic device, the electronic device starts the handwriting function. The handwriting function is used to receive operation information input by the stylus in the writing interface.

[0146] It should be understood that if the stylus is hovering above the display screen of the electronic device, the electronic device can determine that the stylus has the intention to write on the electronic device, that is, the stylus wants to perform a writing operation such as text input, drawing, signature, etc. on the electronic device. That is, after the stylus hovers above the display screen of the electronic device, the electronic device can determine that the stylus has performed a writing preparation operation. At this time, the electronic device can directly start the handwriting function to enable the electronic device to receive operation information input by the stylus in the writing interface. Wherein, the writing preparation operation of the stylus can be understood as the writing operation before the stylus writes.

[0147] In some embodiments, the electronic device can determine that the stylus is hovering above the display screen of the electronic device by the distance between the stylus and the display screen of the electronic device being less than or equal to a first preset distance.

[0148] It should be understood that, referring to Figure 9 , the distance between the stylus and the display screen of the electronic device can represent the distance L between the tip of the stylus 910 and the display screen of the electronic device 920.

[0149] Optionally, the first preset distance can include 0-15 millimeters. For example, the distance between the stylus and the display screen of the electronic device can be 3 millimeters, 4 millimeters, 6 millimeters, 8 millimeters, 10 millimeters, or 12 millimeters, etc. Of course, the first preset distance can also be set to different values according to different actual application scenarios, and the embodiments of the present application do not make limitations here.

[0150] Based on the above embodiments, if the distance between the stylus and the display screen of the electronic device does not exceed the first preset distance, the electronic device can determine that the stylus is hovering above the display screen of the electronic device, that is, the stylus has the intention to write in the writing interface. The electronic device can directly start the handwriting function to realize the function of writing as soon as the stylus is lifted, and improve the fluency of writing.

[0151] In other embodiments, the electronic device can also determine that the stylus is hovering above the display screen of the electronic device when the distance between the stylus and the display screen of the electronic device is less than or equal to the first preset distance for a time period reaching the first preset time period.

[0152] It should be noted that the time period for which the distance between the stylus and the display screen of the electronic device is less than or equal to the first preset distance reaching the first preset time period can be understood as that the stylus is hovering within the first preset distance from the display screen of the electronic device, and the hovering action lasts for more than the first preset time period.

[0153] Based on this, when the stylus is hovering within the first preset distance from the display screen of the electronic device, and the stylus stays within the first preset distance for more than the first preset time period, the electronic device can determine that the stylus is hovering above the display screen of the electronic device, and the stylus has the intention of writing in the writing interface. The electronic device can directly open the handwriting function to quickly enter the writing mode.

[0154] In some embodiments, the electronic device can also determine that the stylus is hovering above the display screen of the electronic device when the stylus is spaced apart from the display screen of the electronic device by the first preset distance.

[0155] For example, referring to Figure 10 , the tip of the stylus 1001 is spaced apart from the display screen of the electronic device 1002 by the first preset distance d, that is, the stylus 1001 is hovering at a position that is the first preset distance d away from the display screen of the electronic device 1002, which indicates that the stylus has the intention of writing in the writing interface, and the electronic device can open the handwriting function.

[0156] In some embodiments, the electronic device can also determine that the stylus is hovering above the display screen of the electronic device when the time period for which the stylus is spaced apart from the display screen of the electronic device by the first preset distance reaches the first preset time period.

[0157] For example, Figure 10 , the tip of the stylus 1001 is spaced apart from the display screen of the electronic device 1002 by the first preset distance d for a time period reaching the first preset time period, which indicates that the stylus has the intention of writing in the writing interface, and the electronic device can open the handwriting function.

[0158] In other embodiments, the electronic device can also directly open the handwriting function by directly contacting the stylus and the display screen of the electronic device.

[0159] For example, referring to Figure 11For example, as shown in FIG. 11, when the stylus 1101 is in contact with the display screen of the electronic device 1102, the user can perform a writing preparation operation on the display screen of the electronic device 1102. In this case, the stylus 1101 can be in contact with the display screen of the electronic device 1102. In this case, it can be considered that the user holds the stylus to have the intention of writing on the electronic device 1102, and the electronic device can quickly open the handwriting function.

[0160] It should be noted that if the stylus is in direct contact with the display screen of the electronic device, the first preset distance between the stylus and the display screen of the electronic device can be considered to be 0 mm. Based on this, it can be indicated that the stylus has the intention of writing in the writing interface, and the electronic device can directly open the handwriting function, which is convenient for the user to use the stylus to quickly perform the writing operation in the writing interface.

[0161] In other embodiments, the electronic device can also open the handwriting function by the time length of the contact between the stylus and the display screen of the electronic device reaching a first preset time length.

[0162] It should be understood that the time length of the contact between the stylus and the display screen of the electronic device reaching the first preset time length can be understood as the stylus and the display screen of the electronic device being in contact within the first preset time length. The first preset time length can be between 0.1 seconds and 15 seconds. For example, the first preset time length can be 0.1 seconds, 0.5 seconds, 1 second, 1.5 seconds, 2 seconds, 5 seconds, 7 seconds, 10 seconds, etc. In actual application, the preset time length can be preconfigured or customized by the user. The embodiments of the present application do not limit this.

[0163] Based on this, when the writing preparation operation of the stylus satisfies that the contact time length between the stylus and the display screen of the electronic device reaches the first preset time length, the electronic device opens the handwriting function to quickly enter the writing mode.

[0164] Optionally, the electronic device can also directly open the handwriting function according to the preset trigger operation performed by the stylus in the preset area in the writing interface.

[0165] The preset trigger operation can include but is not limited to touch, single click, double click, double finger sliding, long press for a preset time length, etc. As an example but not limited, assuming that the writing interface is the display interface 400 in the example shown in FIG. 4, the preset area can be the content display interface 420 in the display interface 400, and the preset trigger operation is a double click operation. When the stylus performs a double click operation in the content display interface 420, the handwriting function can be directly opened to quickly enter the writing mode. Figure 4

[0166] ​Optionally, any two or more of the above-mentioned possible embodiments of the operation mode for triggering the electronic device to start the handwriting function can also be pre-set in the electronic device, so that the electronic device starts the handwriting function immediately after detecting any one of the operation modes. In this way, the flexibility of starting the handwriting function can be improved by increasing the triggering operation for starting the handwriting function. In actual applications, the use habits of different users in different scenarios can also be met, and the individuality of user experience can be improved.

[0167] For example, the pre-set operation mode for triggering the electronic device to start the handwriting function in the electronic device can include, but is not limited to, the following: the distance between the stylus and the display screen of the electronic device is less than or equal to a first preset distance, the stylus is spaced apart from the display screen of the electronic device by a first preset distance, the stylus is spaced apart from the display screen of the electronic device by the first preset distance for a first preset time length, the stylus directly contacts the display screen of the electronic device, the stylus contacts the display screen of the electronic device for a first preset time length, the distance between the stylus and the display screen of the electronic device is less than or equal to the first preset distance for the first preset time length, the stylus performs a preset triggering operation in a preset area of the writing interface, and the like.

[0168] It can be understood that the specific values of the first preset time length and the first preset distance in the above-mentioned possible examples can be the same or different.

[0169] In the embodiments of the present application, the handwriting function can refer to the function of writing characters or drawing graphics on the display screen (or touch screen) of the electronic device using a stylus or a finger. In actual applications, when writing on the display screen (or touch screen) of the electronic device using a stylus or a finger, the recognition system built in the electronic device can recognize the written content and display the recognized written content on the display screen of the electronic device. The written content can be the handwriting corresponding to the sliding track of the user on the display screen of the electronic device, or the various fonts written by the user on the display screen of the electronic device can be converted into standard fonts recognizable by the electronic device.

[0170] In some embodiments, the operation of starting the handwriting function of the electronic device can specifically include an icon automatic lighting operation.

[0171] In one example, assuming that the display interface 300 shown in Figure 3 is a handwriting interface, see Figure 12If the electronic device determines that the stylus is hovering over the display screen of the electronic device, the electronic device can display a handwriting function opening interface 1200, which can include a first toolbar 1200a, a handwriting input interface 1200b, and a second toolbar 1200c.

[0172] The first toolbar 1200a can display a bold control 1211, an italic control 1212, an underline control 1213, a strike-through control 1214, a superscript / subscript button 1215, a font color button 1216, a handwriting icon 1217, a previous step control 1218, a next step control 1219, and a confirmation control 1220, and the like. The handwriting input interface 1200b is used to display the writing content input by the user. The second toolbar 1200c can include a control 1221 for returning to the display interface 300, a color selection control 1222, a brush selection control 1223, an eraser tool 1224, a picture adding control 1225, a voice input control 1226, and a setting control 1227, and the like.

[0173] Referring to Figure 12 In the case where the electronic device determines that the stylus is hovering over the display screen of the electronic device, the electronic device can light up the handwriting icon 1217 in the first toolbar 1200a in the handwriting function opening interface 1200, and / or light up the icon corresponding to the brush selection control 1223 in the second toolbar 1200c in the handwriting function opening interface 1200, so that the electronic device can receive the writing operation information input by the stylus in the handwriting input interface 1200b and display the writing content input by the user in the handwriting input interface 1200b.

[0174] In Figure 12 In the example, the operation of lighting up the handwriting icon 1217 in the first toolbar 1200a in the handwriting function opening interface 1200 and / or the operation of lighting up the icon corresponding to the brush selection control 1223 in the second toolbar 1200c in the handwriting function opening interface 1200 can be understood as the operation of the electronic device opening the handwriting function. After the handwriting icon 1217 in the first toolbar 1200a is lit up and / or the icon corresponding to the brush selection control 1223 in the second toolbar 1200c is lit up, it can be considered that the electronic device has started the handwriting function, and the writing operation can be directly performed using the stylus.

[0175] In some embodiments, the operation of the electronic device opening the handwriting function can further include an automatic expansion operation of the handwriting toolbar.

[0176] Still referring to the above Figure 12For example, the operation of displaying the first toolbar 1200a and / or the second toolbar 1200c in the handwriting function opening interface 1200 can be understood as a handwriting toolbar automatic expansion operation. Of course, in a possible example, the first toolbar 1200a and / or the second toolbar 1200c can also be displayed directly in the handwriting function opening interface 1200, and the operation of displaying the first toolbar 1200a and / or the second toolbar 1200c can be understood as a handwriting toolbar automatic expansion operation. Figure 3 The first toolbar 1200a and / or the second toolbar 1200c in the handwriting function opening interface 1200 can be displayed directly in the display interface 300 shown in Figure 12 , and the operation of displaying the first toolbar 1200a and / or the second toolbar 1200c can be understood as a handwriting toolbar automatic expansion operation.

[0177] In some embodiments, the operation of the electronic device to open the handwriting function can specifically include an icon automatic lighting operation and a handwriting toolbar automatic expansion operation.

[0178] In another example, referring to Figure 13 , after determining that the stylus is hovering over the display screen of the electronic device, the electronic device can directly light up the handwriting icon 1311 in the first toolbar 1300a in the handwriting function opening interface 1300, and automatically expand the brush selection toolbar 1312a corresponding to the brush selection control 1312 in the second toolbar 1300c, so as to directly use the default brush in the brush selection toolbar 1312a for writing operation.

[0179] In the above example, the operation of lighting up the handwriting icon 1311 in the first toolbar 1300a in the handwriting function opening interface 1300 can be understood as an icon automatic lighting operation, and the operation of automatically displaying the brush selection toolbar 1312a corresponding to the brush selection control 1312 in the second toolbar 1300c can be understood as a handwriting toolbar automatic expansion operation. Therefore, in the case of lighting up the handwriting icon 1311 in the first toolbar 1300a and automatically displaying the brush selection toolbar 1312a corresponding to the brush selection control 1312 in the second toolbar 1300c, the electronic device can be considered to have started the handwriting function, and the electronic device can directly receive the writing operation information input by the stylus in the writing interface. The above Figure 13 In the example, other contents included in the handwriting function opening interface 1300 can refer to the related description in the foregoing Figure 12 , and will not be described here.

[0180] In other examples, the operation of the electronic device to open the handwriting function can specifically include an icon automatic lighting operation and a handwriting toolbar automatic expansion operation.

[0181] For example, the handwriting interface is the display interface 500 shown in the foregoing Figure 5 , referring to Figure 14If it is determined that the stylus is hovering over the display screen of the electronic device, the electronic device can further add a handwriting icon 1410 in the handwriting function opening interface 1400 to open the handwriting function. It can be understood that, compared to the display interface 500 shown in FIG. 13A, the handwriting function opening interface 1400 has the handwriting icon 1410 added. That is, in this example, the added icon is the handwriting icon 1410, that is, the operation of adding the handwriting icon 1410 in the handwriting function opening interface 1400 can be understood as that the electronic device starts the handwriting function, and the handwriting operation can be directly performed by using the stylus. Figure 5

[0182] It can be understood that the operation of the electronic device opening the handwriting function can further include the adding icon operation and the handwriting toolbar automatic expansion operation.

[0183] For example, if it is determined that the stylus is hovering over the display screen of the electronic device, the electronic device can also add a handwriting icon 1511 in the handwriting function opening interface 1500 shown in FIG. 15A, and display a brush selection toolbar 1531a corresponding to the brush selection control 1531 in the second toolbar 1530 to open the handwriting function. In other words, in this example, the operation of adding the handwriting icon 1511 and displaying the brush selection toolbar 1531a corresponding to the brush selection control 1531 in the second toolbar 1530 can be understood as that the electronic device starts the handwriting function, and the electronic device can directly receive the handwriting operation information input by the stylus in the writing interface. Figure 15

[0184] Of course, in other examples, according to different handwriting interfaces, the interface or the display toolbar of the electronic device when starting the handwriting function after the electronic device determines that the stylus is hovering over the display screen of the electronic device can be different, and the embodiments of the present application are not limited thereto.

[0185] Based on the handwriting function starting method described above, the handwriting function can be directly opened after it is determined that the stylus is hovering over the display screen of the electronic device, which effectively avoids the situation that the handwriting function needs to be opened after a long operation step, simplifies the operation step of opening the handwriting function, and improves the handwriting function opening efficiency. In this way, the pen can be quickly started to write in the writing interface, the interaction between the stylus and the electronic device is more natural and efficient, and the user experience is improved.

[0186] Optionally, when the electronic device opens the handwriting function, the first prompt information can be displayed, and the first prompt information can be used to prompt that the handwriting function has been opened.

[0187] ​​Optionally, after the electronic device displays the writing interface, the electronic device can also display second prompt information on the display screen of the electronic device, which can be used to prompt that the handwriting function is not started.

[0188] It should be understood that the second prompt information can include prompt information about whether to start the writing function. In the case of detecting that the user indicates to start the writing function, the electronic device can directly start the writing function. In the case of detecting that the user indicates not to start the writing function, the electronic device can not start the writing function.

[0189] Optionally, the second prompt information can also include the reason for not starting the handwriting function and / or the operation corresponding to the prompt to start the handwriting function. In this way, the user can correct the writing preparation operation of the handwriting pen to quickly start the writing function with the help of the second prompt information.

[0190] As Figure 16 Fig. 16 shows a flowchart of another handwriting function starting method 1600 provided by an embodiment of the present application. As shown in Fig. 16, the handwriting function starting method 1600 can include the following steps: Figure 16 The handwriting function starting method 1600 can also be executed by an electronic device. The handwriting function starting method 1600 can include the following steps:

[0191] Step 1601: The electronic device displays an interface of a first application.

[0192] It should be understood that in the embodiments of the present application, the first application can be a writing application, for example, the writing application can be the aforementioned Figure 1 memo APP 110, note APP, drawing APP, or sketching APP, etc. The first application can also be any application installed in the electronic device, for example, a video playing application, etc.

[0193] The interface of the first application displayed in the electronic device can be any interface. In one example, assuming that the first application is the aforementioned Figure 1 memo APP 110, the interface of the first application displayed in the electronic device can be the display interface 300 shown in Fig. 3, or the display interface 400 in the example shown in Fig. 4, or the aforementioned display interface 500 shown in Fig. 5. In another example, assuming that the first application is a video playing application, the interface of the first application displayed in the electronic device can be the home page displayed after the video playing application is started, or can be a playing page corresponding to playing any video. Figure 3 Figure 4 Figure 5

[0194] In some examples, the display mode of the interface of the first application includes but is not limited to the following modes: the user touches an application icon corresponding to the first application, starts the first application through a smart voice assistant, or triggers a shortcut key to start the first application, etc. ​​​

[0195] At step 1602, the electronic device starts the handwriting function if the touch operation and the writing preparation operation of the stylus are detected simultaneously. The handwriting function is used to receive operation information input by the stylus in the interface of the first application.

[0196] It is understandable that, in the embodiments of the present application, the touch operation and the writing preparation operation of the stylus jointly constitute the trigger operation for starting the handwriting function. In this way, using two operations as trigger conditions can ensure that the starting of the handwriting function is more accurate and reliable, thereby improving the user experience. In addition, it can also avoid the function conflict caused by the fact that a single operation may have been used to start other functions when the handwriting function is started only by relying on a single user operation or stylus operation.

[0197] In some embodiments, the touch operation can be a touch operation, i.e., an operation in which the user touches the display screen of the electronic device.

[0198] In one example, referring to Figure 17 , the touch operation can be an operation in which the user touches the display screen by three fingers.

[0199] In other examples, the touch operation of the user can also be any one of the possible gesture operations in the various gestures (1) to (10) shown in Figure 18 .

[0200] In some embodiments, the touch operation of the user can also be a control operation, i.e., an operation of controlling the display of a writing interface on the display screen of the electronic device and starting the writing function. For example, the control operation can include one or more of key input, gesture recognition, body language recognition, speech recognition, expression recognition, eye movement recognition, and face recognition.

[0201] In some embodiments, the writing preparation operation of the stylus can also be the operation in which the stylus is hovering over the display screen of the electronic device in the handwriting starting method 800 described above.

[0202] In some embodiments, the operation in which the stylus is hovering over the display screen of the electronic device can include an operation in which the distance between the stylus and the display screen of the electronic device is less than or equal to a first preset distance.

[0203] In some embodiments, the operation in which the stylus is hovering over the display screen of the electronic device can also include an operation in which the distance between the stylus and the display screen of the electronic device is less than or equal to a first preset distance for a duration of a first preset duration.

[0204] The writing preparation operation of the stylus in the above embodiments can refer to the related content in the handwriting starting method 800 described above, which will not be repeated here.

[0205] Based on the above possible embodiments, the user's touch operation and the stylus's writing preparation operation can be performed simultaneously; a second preset time interval can also be established between the user's touch operation and the stylus's writing preparation operation. The second preset time interval can be between 0.1 seconds and 30 seconds. For example, the value of the second preset time interval can be 0.1 seconds, 0.5 seconds, 1 second, 2 seconds, 2.4 seconds, 2.7 seconds, 5 seconds, 10 seconds, 15 seconds, 20 seconds, etc.

[0206] It should be noted that, in practical applications, the user's touch operation and the stylus's writing preparation operation can be the same. As an example, and not a limitation, the user's touch operation can be the user touching the display screen with a single finger; the stylus's writing preparation operation can be the stylus tip touching the electronic device's display screen. Therefore, the user's touch operation and the stylus's writing preparation operation can be considered the same. Of course, in practical applications, the user's touch operation and the stylus's writing preparation operation can also be different, and this application does not limit this.

[0207] In some embodiments, the electronic device can detect the touch operation and the writing preparation operation of the stylus within a first preset area.

[0208] It should be understood that the first preset area can be an area corresponding to the display screen of the electronic device. In one possible example, the size of the first preset area is the same as the size of the display screen of the electronic device, that is, the touch operation and the writing preparation operation of the stylus are detected on the display screen of the electronic device.

[0209] In another possible example, the first preset area could also be a portion of the display screen of an electronic device. For example, the first preset area could be... Figure 4 The content display area in the shown display interface 400 corresponds to the area of ​​the display interface 420, etc. This allows for rapid detection of touch operations and stylus writing preparation operations in specific areas, significantly improving the convenience and efficiency of user interaction. It also effectively reduces the processing steps of the display screen and simplifies the display screen manufacturing process.

[0210] Based on the above possible implementation methods, since the detected touch operation and the writing preparation operation of the stylus are detected in the first preset area of ​​the electronic device, the situation of erroneously triggering the display of the writing interface when the stylus is removed from the electronic device due to needs such as charging can be effectively avoided by limiting the area, thus ensuring the accurate matching of the user's intention and the actual operation.

[0211] In other embodiments, the first preset area can also be an area other than the display screen of the electronic device. For example, the other area is an area on the outer frame of the electronic device, which can be used by the electronic device to detect the touch operation and / or the writing preparation operation of the stylus, so as to start the writing function when the electronic device detects the touch operation and the writing preparation operation of the stylus.

[0212] In some embodiments, the interface of the first application does not support the modification operation before the writing function is started.

[0213] It should be understood that the modification operation can include at least one of the adding operation, the updating operation, and the deleting operation performed by the user on the content in the interface of the first application.

[0214] It is not difficult to understand that the electronic device starts the writing function only after detecting the touch operation and the writing preparation operation of the stylus at the same time, that is, the user can perform the writing operation in the interface of the first application by using the stylus, so that the electronic device receives the operation information input by the stylus in the interface of the first application. Therefore, before the electronic device starts the writing function, the user cannot temporarily use the stylus to modify the content displayed in the interface of the first application.

[0215] It should be noted that in the embodiments of the present application, and the embodiments described above Figure 8 The difference between the embodiments shown in the method 800 is mainly that, after the writing interface has been displayed, the electronic device starts the writing function after determining that the stylus is hovering over the display screen of the electronic device, so that the stylus can be directly used to perform the writing operation in the writing interface.

[0216] In the method 1600, it is not limited whether the interface currently displayed by the electronic device is any interface in the writing application, that is, in the method 1600, the electronic device first displays any interface, and then directly starts the writing function in the any interface after detecting the touch operation and the writing preparation operation of the stylus at the same time, that is, the user can perform the writing operation in the any interface.

[0217] Optionally, the electronic device can also display a third prompt information before or after displaying the interface of the first application, and the third prompt information can be used to indicate that the writing function is successfully started.

[0218] Optionally, after the electronic device displays the interface of the first application, the electronic device can also display a fourth prompt information, and the fourth prompt information can be used to indicate that the writing function is not started.

[0219] It should be understood that the fourth prompt information can further include prompt information about whether to start the writing function. In a case where it is detected that the user indicates to start the writing function, the electronic device can directly start the writing function. In a case where it is detected that the user indicates not to start the writing function, the electronic device can not start the writing function.

[0220] In other examples, the fourth prompt information can further include a reason for not starting the handwriting function and / or operation information for guiding the user to start the writing function, and the like. In this way, the user can input correct operations to start the writing function with the aid of the fourth prompt information.

[0221] In addition to the possible implementation manners described above, in other possible implementation manners, the handwriting function starting method can further include that, after the electronic device simultaneously detects the touch operation and the writing preparation operation of the stylus, the electronic device first displays the interface of the first application and then starts the handwriting function. In this way, the effect of writing as soon as the stylus is lifted can be achieved, and the operation path before writing is further reduced on the basis of the method 1600, and the efficiency and fluency of the writing operation are further improved.

[0222] In this possible implementation manner, the touch operation and the writing preparation operation of the stylus detected by the electronic device, the first application, the interface of the first application, and the specific operation of starting the handwriting function can refer to the content in the foregoing related embodiments, and will not be described here again.

[0223] Based on the handwriting function starting method described above, the touch operation and the writing preparation operation of the stylus corresponding to the first application can be preconfigured. For example, the interface currently displayed by the electronic device can be the desktop 100 or the lock screen interface shown in FIG. 1, or the electronic device is in a screen-off state. If the electronic device simultaneously detects the touch operation and the writing preparation operation of the stylus, the electronic device can display any interface in which writing can be performed and start the handwriting function. Figure 1

[0224] Based on the possible implementation manners described above, the user can quickly enter the writing mode, and the operation step of displaying the writing interface is further reduced, the fluency of writing and the efficiency of the writing operation are further improved, and the user experience is improved. In addition, since the operation for triggering the handwriting function to start includes the touch operation and the writing preparation operation of the stylus, that is, the operation is composed of multiple operations, the misoperation (or mis-triggering) caused by the operation being too simple or common can be further effectively avoided.

[0225] It should be understood that the size of the serial number of each step in the foregoing embodiments does not mean the execution sequence, and the execution sequence of each process should be determined according to its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
