Abstract

The application provides a processing method and a processing device for touch pen operation, wherein when the touch pen detects that the touch pen is in a writing state, a pressure value of a writing end, namely a writing pressure value, is acquired. Further, a processor in the touch control pen directly judges whether the writing pressure value exceeds a preset pressure threshold value, and when the writing pressure exceeds the preset pressure threshold value, the touch control pen directly outputs a prompt signal. The process saves the transmission time for transmitting the writing pressure value to the electronic equipment, so that the time delay for reminding that the writing pressure is high is reduced, namely the response speed for reminding that the writing pressure is high is improved. Moreover, the prompt signal is directly output by the feedback device of the touch control pen, so that a user can directly perceive the feedback of the touch control pen, and the user experience is improved.

Detailed Description

The terms first, second, third and the like in the description and in the claims and in the drawings are used for distinguishing between different objects and not for limiting the specified order.

In embodiments of the application, words such as "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g." in an embodiment should not be taken as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

Fig. 1 is a schematic view of a scene, as shown in fig. 1, where the scene includes an electronic device 1 and a stylus (stylus) 2. The electronic device 1 has a touch screen 11, which touch screen 11 may be referred to as a touch screen, the electronic device 1 being exemplified in fig. 1 as a folding screen mobile phone. The stylus 2 may be referred to as a stylus.

The electronic device 1 performs an operation responsive to the input based on the input of the stylus 2. In an embodiment, the stylus 2 and the electronic device 1 may be interconnected through a communication network to implement interaction of wireless signals. The communication network may include, but is not limited to: a WiFi hotspot network, a WiFi peer-to-peer (P2P) network, a bluetooth network, a zigbee network, or a near field communication (NEAR FIELD communication) network.

The stylus 2 may be, but is not limited to, an electromagnetic pen and a capacitive pen. When the stylus 2 is an electromagnetic pen, an electromagnetic induction plate needs to be integrated on the touch screen 11 of the electronic device 1. Coils are distributed on the electromagnetic induction plate, and coils are integrated in the electromagnetic pen. Based on the electromagnetic induction principle, the electromagnetic pen can accumulate electric energy along with the movement of the electromagnetic pen in the range of the magnetic field generated by the electromagnetic induction plate. The electromagnetic pen can transmit the accumulated electric energy to the electromagnetic induction plate through the coil in the electromagnetic pen by free oscillation. The electromagnetic induction plate can scan the coil on the electromagnetic induction plate based on the electric energy from the electromagnetic pen, and calculate the position of the electromagnetic pen on the touch screen 11.

Capacitive pens may include passive capacitive pens and active capacitive pens. Passive capacitive pens may be referred to as passive capacitive pens and active capacitive pens may be referred to as active capacitive pens. It should be understood that the stylus according to the embodiments of the present application is an active capacitive stylus.

One or more electrodes may be provided in the active capacitive pen (e.g., within the pen tip), through which the active capacitive pen may emit a signal. When the stylus 2 is an active capacitive stylus, an electrode array is required to be integrated on the touch screen 11 of the electronic device 1. In one embodiment, the electrode array may be a capacitive electrode array. The electronic device 1 may receive a signal from the active capacitive pen through the electrode array, and further identify the position of the active capacitive pen on the touch screen and the tilt angle of the active capacitive pen based on the change of the capacitance value on the touch screen 11 when the signal is received. It should be understood that the stylus used in the embodiments of the present application is an active capacitive stylus, or simply an active stylus.

As shown in fig. 2 (1), the folding screen mobile phone is in a fully unfolded state, from which the state shown in fig. 2 (2) can be obtained by bending outwards, and from the state shown in fig. 2 (2), the state shown in fig. 2 (3) is obtained, and in the state shown in fig. 2 (3), the mobile phone is in a fully folded state. The cover plate of the flexible screen is mainly a soft cover plate, so that the flexible screen can be bent. Because the soft cover plate is softer, when the touch pen is used for writing on the flexible screen, scratches are easily left on the cover plate, so that the service life of the flexible screen is influenced.

In order to solve the above problems, an embodiment of the present application provides a method for processing operation of a stylus, where when the stylus is in a writing state, a pressure value between the stylus and a touch screen of an electronic device is obtained, and if the pressure value is greater than or equal to a preset pressure threshold, the user is prompted to have excessive pressure. After the user perceives the prompt, the pressure is adjusted. Therefore, the scheme can prompt the user in time when detecting that the pressure of the touch pen is large, so that the user can adjust the pressure in time, and the situation that the service life of the touch screen is shortened due to overlarge pressure of the touch pen is avoided, and the service life of the touch screen can be prolonged to a certain extent by adopting the scheme.

The writing state of the stylus means that the stylus is in a working state, and in this state, the stylus can perform corresponding operations on the touch screen, such as clicking, double clicking, long pressing, writing, drawing graphics, and the like.

Fig. 3 is a schematic structural diagram of a stylus according to an embodiment of the present application, and as shown in fig. 3, the stylus may include a nib 101, a pen holder 102, and a rear cover 103. The inside of the pen holder 102 is of a hollow structure, the pen point 101 and the rear cover 103 are respectively positioned at two ends of the pen holder 102, and the rear cover 103 and the pen holder 102 can be inserted or clamped.

Fig. 4 is a schematic view of a part of an internal structure of a stylus according to an embodiment of the present application, as shown in fig. 4, the stylus further includes a spindle assembly 104, the spindle assembly 104 is located in the pen holder 102, and the spindle assembly 104 is slidably disposed in the pen holder 102. Spindle assembly 104 has external threads thereon, and nib 101 includes a writing end 105 and a connecting end 106, wherein connecting end 106 of nib 101 has internal threads (not shown) that mate with the external threads.

When the spindle assembly 104 is assembled into the barrel 102, the connecting end 106 of the nib 101 extends into the barrel 102 and is threadably coupled to the spindle assembly 104. In other examples, the connection end 106 of the pen tip 101 and the spindle assembly 104 may be detachably connected by a snap fit or the like. The pen tip 101 is replaced by detachably connecting the connecting end 106 of the pen tip 101 with the spindle assembly 104.

As shown in fig. 3, a gap 1011 is formed between the nib 101 and the barrel 102, so that when the writing end 105 of the nib 101 is subjected to an external force, the nib 101 can move towards the barrel 102, and the movement of the nib 101 drives the spindle assembly 104 to move in the barrel 102. As shown in fig. 4, the spindle assembly 104 is provided with a pressure sensing assembly 107, a part of the pressure sensing assembly 107 is fixedly connected with a fixing structure in the pen holder 102, and a part of the pressure sensing assembly 107 is fixedly connected with the spindle assembly 104. Thus, when the spindle assembly 104 moves along with the pen tip 101, since a part of the pressure sensing assembly 107 is fixedly connected with the fixing structure in the pen holder 102, the movement of the spindle assembly 104 drives the pressure sensing assembly 107 to deform, the deformation of the pressure sensing assembly 107 is transmitted to the circuit board 108 (for example, the pressure sensing assembly 107 and the circuit board 108 can be electrically connected through a wire or a flexible circuit board), and the circuit board 108 detects the pressure of the writing end 105 of the pen tip 101 according to the deformation of the pressure sensing assembly 107, so that the writing line thickness is controlled according to the pressure of the writing end 105 of the pen tip 101.

Note that the pressure detection of the pen tip 101 includes, but is not limited to, the above method. For example, the pressure of the pen tip 101 may be detected by a pressure sensor provided in the writing end 105 of the pen tip 101.

As shown in fig. 4, the stylus further includes a plurality of electrodes, which are described herein as the stylus including the first emitter electrode 109, the ground electrode 110, and the second emitter electrode 111, however, in other embodiments, the stylus may further include other numbers and functions of electrodes, which are not described herein.

In an exemplary embodiment, the second emitter electrode 111 may be located on an inner wall of the barrel 102. In another example, the second emitter electrode 111 may also be located on the spindle assembly 104. The ground electrode 110 may be located between the first and second transmitting electrodes 109 and 111, or the ground electrode 110 may be located around the outer circumference of the first and second transmitting electrodes 109 and 111, the ground electrode 110 serving to reduce coupling of the first and second transmitting electrodes 109 and 111 with each other.

The first transmitting electrode 109, the ground electrode 110, and the second transmitting electrode 111 are all electrically connected to the circuit board 108. The first transmitting electrode 109 may be located within the nib 101 near the writing end 105.

The circuit board 108 may be configured as a control board that may provide signals to the first and second transmitting electrodes 109 and 111, respectively.

The first transmitting electrode 109 is configured to transmit a first signal, and when the first transmitting electrode 109 is close to the touch screen of the electronic device, a coupling capacitance is formed between the first transmitting electrode 109 and the touch screen of the electronic device, so that the electronic device can receive the first signal. When the electronic device receives the first signal from the stylus, the capacitance value at the corresponding position of the touch screen changes, and the electronic device can determine the position of the stylus (or the nib of the stylus) on the touch screen based on the change of the capacitance value on the touch screen.

In an exemplary embodiment, the second transmitting electrode 111 is configured to transmit a second signal, and the electronic device may determine the tilt angle of the stylus according to the received second signal. The positions of the first transmitting electrode 109 and the second transmitting electrode 111 in the touch pen are different, so when the electronic device receives the first signal and the second signal from the touch pen, the capacitance values at two positions on the touch screen will change. The electronic device may obtain the tilt angle of the stylus according to the distance between the first transmitting electrode 109 and the second transmitting electrode 111 and the distance between two positions where the capacitance value changes on the touch screen.

In an embodiment of the present application, as shown in fig. 4, the stylus further includes a battery assembly 112, and the battery assembly 112 is configured to provide power to the circuit board 108.

The electronic device may also comprise feedback means, such as a vibration motor, a status indicator or a speaker, etc.

The following will describe in detail embodiments of a method for processing a stylus operation according to an embodiment of the present application with reference to the accompanying drawings.

In one application scenario, as shown in fig. 1, a folding screen mobile phone 1 is configured with a stylus 2, and writing is performed on a touch screen 11 of the folding screen mobile phone 1 by using the stylus 2. In such a scenario, the following two possible implementations may be included:

One possible implementation is: no feedback devices, such as vibration motors, status indicators, and/or speakers, etc., are provided within the stylus. In this possible implementation manner, the electronic device interacting with the stylus determines the pressure value in the writing state sent by the stylus, and if the pressure value is greater than or equal to the preset pressure threshold, the electronic device is controlled to output a prompt signal for reminding the user that the pressure of the stylus is too high.

Another possible implementation is: and in the scene, a processor in the touch pen judges whether the pressure value of the touch pen is greater than or equal to a preset pressure threshold value, and if so, the processor directly controls the feedback device in the touch pen to output a corresponding prompt signal.

Optionally, the electronic device may further receive a pressure value in a writing state sent by the stylus, and determine whether the pressure value is greater than or equal to a preset pressure threshold, and if so, trigger the electronic device to output a prompt signal that the pressure of the stylus is too high.

For the implementation manner that the feedback device is not disposed in the stylus, the embodiment of the application provides a processing flow of the stylus operation shown in fig. 7, and the method is applied to an electronic device that interacts with the stylus, for example, an electronic device configured with the stylus. As shown in fig. 7, the method may include the steps of:

s11, establishing wireless connection between the touch pen and the electronic equipment.

Taking the example of establishing bluetooth connection between the stylus and the electronic device as an example, in other embodiments of the present application, wireless connection based on other than bluetooth protocol may be established between the stylus and the electronic device, and the present application does not limit the type of wireless communication between the stylus and the electronic device.

In one possible implementation, when the stylus is first connected to the electronic device, the process of establishing the wireless connection may include three phases: pairing phase, bluetooth information transmission phase and wireless channel establishment phase.

The pairing stage is that the touch pen sends handshake data to the electronic equipment, the electronic equipment performs equipment verification on the touch pen by the received handshake data of the touch pen, and a verification result is returned to the touch pen.

The handshake data may include device related information of the stylus, such as a device name of the stylus, a product serial number, software system information, product hardware information, etc., which the present application is not limited to.

The electronic equipment stores the equipment information of the adaptive touch pen when leaving the factory, namely the electronic equipment stores the equipment information such as the equipment name, the equipment model, the version information of a software system, the product hardware information and the like of the adaptive touch pen. And the electronic equipment performs equipment verification on the received equipment information of the touch pen and the equipment information of the touch pen stored by the electronic equipment.

The stylus adapted to the electronic device may be one or more types, and the electronic device may store device information of each type of stylus adapted, which is not limited in the present application.

If the electronic device fails to verify the information of the device of the touch pen, that is, the touch pen is not the touch pen matched with the electronic device, the current pairing process can be terminated, and other subsequent steps are not executed.

If the electronic equipment passes the verification of the touch pen, a verification result indicating the verification pass is returned to the touch pen, and after the touch pen receives the verification result, bluetooth information is sent to the electronic equipment.

Further, the electronic equipment compares the received Bluetooth information with the Bluetooth information of the adaptive touch pen stored in the electronic equipment, namely, the Bluetooth information of the touch pen is checked, and a Bluetooth information check result is returned to the touch pen.

In an example, the bluetooth information of the stylus may include: the application is not limited to bluetooth connection information such as bluetooth protocol information, wireless information, MAC (media access control) address information at the time of bluetooth connection, internet protocol address (Internet protocol address, IP ADDRESS) and the like of the stylus. The Bluetooth information is used for supporting the establishment of a Bluetooth channel between the electronic device and the stylus.

If the Bluetooth information of the touch pen is checked by the electronic equipment, the follow-up steps are continuously executed, such as a connection prompt popup window is displayed, the connection prompt popup window is used for displaying whether the touch pen is connected or not, and controls of yes and no can be displayed, and further, corresponding processes are executed according to the selection of a user. For example, if the user selects "yes", the process of establishing a wireless channel (such as a bluetooth channel) between the stylus and the electronic device is continued. If the user selects "no," the current flow may be terminated without performing subsequent steps.

Optionally, the connection prompt popup window may further display at least one of a product signal of the current stylus, contents of a manufacturer, and the like, and contents of a remaining capacity of the current stylus, a battery identifier, a charging progress, and the like.

If the electronic device fails to verify the bluetooth information of the stylus (i.e., the bluetooth information of the stylus fails to verify), the current flow may be terminated, i.e., no further steps are performed.

S12, after the stylus determines that the stylus is in a writing state, a writing pressure value is collected.

In an embodiment of the application, the writing state is the first condition of the claims.

In one possible implementation manner, the writing state includes that a tip of the stylus is in contact with the touch screen, and in addition, other contents may be included, for example, a duration of time that the tip is in contact with the touch screen exceeds a preset duration, where the preset duration may be set according to actual requirements.

When the stylus is in a writing state, the stylus can operate on a touch screen of the electronic device, such as clicking, double clicking, long pressing, writing, drawing graphics and the like.

In the embodiment of the application, after the stylus enters a writing state, the stylus triggers an internal sensor to collect corresponding information, and the collected information can be called as status information of the stylus, for example, the status information includes the writing pressure value.

When the pen point of the touch pen contacts the touch screen of the electronic device, the capacitance value of the contact position on the touch screen changes, the electronic device determines that the touch pen is in a writing state based on the capacitance value, the electronic device sends a signal to the touch pen, and the touch pen determines that the touch pen is in the writing state currently after receiving the signal. After the touch pen determines that the touch pen contacts with the touch screen, a corresponding sensor in the touch pen is triggered to collect state information of the touch pen, for example, a pressure sensor in the touch pen is utilized to collect pressure data of a writing end, namely a writing pressure value.

And S13, the stylus sends the writing pressure value to the electronic equipment.

The stylus reports its own status information (including the writing pressure value) to the electronic device via a wireless channel (e.g., a bluetooth channel) between the stylus and the electronic device. S14, the electronic equipment judges whether the writing pressure value is larger than or equal to a preset pressure threshold value; if yes, executing S15; if not, S16 is performed.

The electronic equipment analyzes the data reported by the touch pen to obtain writing pressure data, and further judges whether the writing pressure value is larger than or equal to a preset pressure threshold value.

In one example, the pressure value may be in g, which characterizes 9.8N/kg.

The preset pressure threshold may be set according to requirements of different touch screen types, for example, the pressure that the flexible screen can withstand is small, so the preset pressure threshold of the flexible screen may be set to a small value, such as 150g. The hard screen can withstand a larger pressure than the flexible screen, and thus the preset pressure threshold of the hard screen can be set to a larger value, for example, 400g or so.

S15, the electronic equipment outputs a prompt signal.

In the embodiment of the application, the prompting signal can comprise at least one of displaying a prompting popup window and outputting other prompting signals.

The prompt popup window comprises prompt information, such as text information, for prompting a user that the pressure of the touch pen is too high. In an exemplary embodiment, other alert signals include, but are not limited to: the vibration motor outputs a vibration signal, and/or the speaker outputs a sound signal, and/or the status indicator outputs a light signal.

As shown in fig. 8, a prompt pop-up window 12 may be displayed on the touch screen 11. The display content of the prompt pop-up window 12 may be set according to actual requirements, as shown in fig. 8, where the display content of the prompt pop-up window 12 may be "you write too much pressure, and risk of damaging the touch screen exists. For example, as shown in fig. 7, the prompt pop-up window 12 is located above the writing position of the stylus 2 on the touch screen 11. Of course, the prompt pop-up window 12 may also be located at any display position of the touch screen 11, which is not limited in the present application.

After the user sees the content of the prompt popup window and/or senses other prompt signals, the writing pressure can be timely adjusted, so that the phenomenon that the user damages a touch screen due to overlarge writing pressure of the touch pen is avoided.

In an exemplary embodiment, the electronic device continues to execute S16 after executing S15, for example, displaying the prompt pop-up window for a preset period of time, e.g., after 5S (or outputting other prompt signal for a preset period of time), and continues to execute S16.

S16, the electronic equipment responds to the operation of the touch pen on the touch screen.

In one case, the writing pressure of the stylus is greater than or equal to a preset pressure threshold of the touch screen, and the electronic device displays a prompt popup window and outputs other prompt signals. And responding to the operation of the touch pen on the touch screen. In another case, the writing pressure of the stylus is less than the preset pressure threshold of the touch screen, and in this case, the prompt popup window and other prompt signals are not displayed, and the operation of the stylus on the touch screen is directly responded.

And the electronic equipment executes response processing matched with the operation type according to the operation type of the touch pen, for example, the touch pen performs clicking operation (or double clicking, long pressing and the like) on the touch screen, and the electronic equipment responds to the operation and executes corresponding processing flow. If the touch pen performs operations such as writing or drawing graphics on the touch screen, the operation of drawing handwriting is directly executed, namely, the water outlet of the touch pen is controlled.

According to the processing method for the operation of the touch pen, when the touch pen is in a writing state, the pressure value of the writing end, namely the writing pressure value, is collected, and the writing pressure value is sent to the electronic equipment. After the electronic equipment determines that the writing pressure value is greater than or equal to the preset pressure threshold, the electronic equipment outputs a prompt signal for prompting a user that the writing pressure is too high, such as at least one of displaying a prompt popup window, outputting a vibration signal by a vibration motor, outputting an alarm signal by a loudspeaker and the like. Therefore, when the touch pen writing pressure is detected to be too high, the corresponding prompt signal is timely output, so that the user can adjust the writing pressure according to the prompt of the prompt signal, the touch screen damage caused by the too high touch pen writing pressure is avoided, and the service life of the touch screen is prolonged.

Aiming at the implementation mode that the feedback device is arranged in the touch control pen, the processor in the touch control pen can judge whether the writing pressure value of the processor exceeds a preset pressure threshold value, and if the writing pressure of the processor is judged to exceed the preset pressure threshold value, the processor directly drives the feedback device in the touch control pen to output a prompt signal.

The embodiment of the application provides another processing method for the operation of the touch control pen shown in fig. 9. As shown in fig. 9, the method may include the steps of:

s21, establishing wireless connection between the touch pen and the electronic equipment.

S22, the stylus acquires a writing pressure value in response to entering a writing state.

The writing state of the present embodiment is the first state of the claims, and the writing pressure value is the pressure value of the claims.

S23, the touch pen reports the acquired writing pressure value to the electronic equipment through wireless communication connection.

The processes of S21 to S23 in this embodiment are the same as those of S11 to S13 in the embodiment shown in fig. 7, and will not be described here again.

S24, judging whether the writing pressure value is larger than or equal to a preset pressure threshold value by the touch pen; if yes, then executing S25; if not, ending the current flow.

S25, the stylus controls a feedback device in the stylus to output a prompt signal.

In this embodiment, a feedback device, such as a vibration motor, a speaker, a status indicator, etc., is disposed in the stylus, and in this scenario, when it is determined that the writing pressure value exceeds the preset pressure threshold, the processor in the stylus may trigger the feedback device in the stylus to output a corresponding prompting signal, such as vibration of the vibration motor, playing of an alarm signal by the speaker, and displaying of a corresponding light signal by the status indicator.

S26, the electronic equipment judges whether the received writing pressure value is larger than or equal to a preset pressure threshold value; if yes, then executing S27; if not, S28 is performed.

S27, the electronic equipment outputs a prompt signal.

The state information of the stylus is sent to the electronic device, so the electronic device can also judge whether the received writing pressure value exceeds a preset pressure threshold value, if so, the electronic device side is triggered to output corresponding prompting signals, such as displaying a prompting popup window, and/or outputting other types of prompting signals, such as vibration, sound signals or optical signals.

The prompt popup window prompts the information of the overlarge writing pressure of the touch pen, so that a user can intuitively and accurately know the overlarge writing pressure of the touch pen, and is convenient for the user to timely know the prompt information of the overlarge writing pressure and further timely adjust the writing pressure.

S28, the electronic equipment responds to the operation of the touch pen on the touch screen.

And if the electronic equipment determines that the writing pressure value exceeds the preset pressure threshold value, controlling the electronic equipment to output a prompt signal, and simultaneously, responding to the operation of the touch pen on the touch screen, for example, the operation of drawing handwriting is executed when the touch pen moves on the touch screen.

If the electronic equipment determines that the writing pressure value is smaller than the preset pressure threshold value, the electronic equipment directly executes the handwriting drawing operation.

It should be understood that steps S26 to S28 are not necessarily performed, that is, steps S21 to S25 in the present embodiment may be performed only, that is, when the stylus only detects that the writing pressure value exceeds the standard, a prompt signal is output, and the electronic device side interacting with the stylus does not need to repeatedly detect and prompt.

According to the processing method for the operation of the touch pen, after the touch pen obtains the writing pressure value, a processor in the touch pen directly judges whether the writing pressure value exceeds the preset pressure threshold value, and when the writing pressure exceeds the preset pressure threshold value, the touch pen directly outputs a prompt signal. The process saves the transmission time for transmitting the writing pressure value to the electronic equipment, so that the time delay for reminding the user of overlarge writing pressure is reduced, namely the response speed for reminding the user of overlarge writing pressure is improved. Moreover, the prompt signal is directly output by the feedback device of the touch control pen, so that a user can directly perceive the feedback of the touch control pen, and the user experience is improved.

Furthermore, the electronic equipment can also continue to execute the process of judging whether the writing pressure value exceeds the standard and outputting the prompting signal if the writing pressure value exceeds the standard, namely if the writing pressure of the touch pen exceeds the standard, the touch pen and the electronic equipment can both output the corresponding prompting signal, and the effectiveness of the prompting signal is improved by both the two devices outputting the prompting signal.

In another application scenario, an electronic device (e.g., a first electronic device) is configured with a stylus with which to operate on a touch screen of another electronic device (e.g., a second electronic device), i.e., a cross-device stylus operation.

As shown in fig. 10, the folding screen mobile phone 501 is a first electronic device, the folding screen mobile phone 501 is configured with a stylus 502 (may be referred to as a first stylus), the tablet device 503 is a second electronic device, and the scene is that the user operates on the tablet device 503 using the stylus 502. As also shown in fig. 11, the tablet device 601 is a first electronic device, the folding screen handset 603 is a second electronic device, and the tablet device 601 is configured with a stylus 602, and the scenario is that the user operates on the folding screen handset 603 using the stylus 602 of the tablet device 601.

In such a scenario, the following two possible implementations may be included:

one possible implementation manner is that when the stylus is used across devices, the writing overvoltage protection mechanism on the electronic device side interacting with the stylus is triggered, that is, the second electronic device directly executes the processing flow of the writing overvoltage protection mechanism, which is the same as the processing method of the stylus operation shown in fig. 7, and is not repeated here. Therefore, under the condition that the writing overvoltage protection mechanism is arranged on the side of the electronic equipment, the electronic equipment is irrelevant to a touch pen used by the electronic equipment, and after the touch pen connected with the electronic equipment is replaced, the electronic equipment can monitor the writing pressure of the touch pen, so that the damage to the touch screen caused by the overlarge writing pressure of the touch pen is avoided, and the service life of the touch screen is prolonged.

Another possible implementation is to provide feedback means within the stylus, such as a vibration motor, status indicator lights, speakers, etc. When the stylus is used across devices, a writing overvoltage protection mechanism on the stylus side may be triggered. However, in the application scenario shown in fig. 11, the writing overvoltage protection mechanism in the stylus 602 is configured with a preset pressure threshold for the touch screen (i.e., hard screen) of the tablet device 601, while the writing overvoltage protection mechanism in the folding screen phone 603 is configured with a preset pressure threshold for the flexible screen of the folding screen phone. When the stylus 602 writes on a folding screen cell phone, the stylus 602 still triggers the writing overvoltage protection mechanism at the preset pressure threshold of the stiff screen. As described above, the pressure that the flexible screen can withstand is smaller, while the pressure that the rigid screen can withstand is larger, for example, the preset pressure threshold of the rigid screen is 400g, and if the writing pressure of the stylus on the flexible screen reaches 600g and far exceeds the threshold (such as 150 g) of the flexible screen, the flexible screen will be damaged by overpressure. Therefore, in this implementation manner, the electronic device interacting with the stylus needs to send the preset pressure threshold corresponding to the touch screen to the stylus, and trigger the stylus to execute the corresponding writing overvoltage protection mechanism according to the preset pressure threshold of the touch screen that is currently written.

Referring to fig. 12, a flowchart of a process of a stylus operation according to another implementation provided by an embodiment of the present application is shown. As shown in fig. 12, the method may include the steps of:

s31, wireless connection is established between the first touch pen and the first electronic equipment.

S32, after the first touch pen enters a writing state, a first writing pressure value is acquired.

The stylus of the present embodiment is in a first condition when the stylus enters a writing state. The writing pressure value is the first pressure value of the claims.

S33, the first stylus reports the first writing pressure value to the first electronic equipment.

S34, the first stylus judges whether the first writing pressure value is larger than or equal to a first preset pressure threshold value. If yes, then execute S35; if not, ending the current flow.

The first preset pressure threshold is matched to a screen type of a touch screen of the first electronic device, e.g., the touch screen of the first electronic device is a flexible screen, and the first preset pressure threshold is about 150 g. The touch screen of the first electronic device is a hard screen, and the first preset pressure threshold is about 400 g.

S35, the first stylus outputs a first prompt signal.

In this embodiment, the first stylus is provided with feedback means, such as at least one of a vibration motor, a status indicator and a speaker. In such a scenario, the first alert signal may include at least one of: a vibration signal output by the vibration motor, an optical signal output by the status indicator, and a sound signal output by the speaker.

Alternatively, the first electronic device may also perform the processes shown in S36 to S38.

S36, the first electronic device judges whether the first writing pressure value is larger than or equal to a first preset pressure threshold value. If yes, then execute S37; if not, S38 is performed.

S37, the first electronic device outputs a second prompt signal.

In one possible implementation, if the first writing pressure value is greater than or equal to a first preset pressure threshold, the touch screen of the first electronic device displays a first prompt pop-up window, where the first prompt pop-up window includes prompt information for prompting that the pressure value of the stylus is too large.

In another possible implementation, the first electronic device includes feedback means, such as at least one of a vibration motor, a status indicator, and a speaker. In such a scenario, the second cue signal may include at least one of: a vibration signal output by the vibration motor, an optical signal output by the status indicator, and a sound signal output by the speaker.

S38, the first electronic device responds to the operation of the touch pen on the first touch screen.

The processes of S31 to S38 in this embodiment are the same as those of S21 to S28 in the embodiment shown in fig. 9, and will not be described here again. In addition, the processes shown in S36 to S38 are optional processes, and are not described here again.

S39, establishing wireless connection between the first touch pen and the second electronic equipment.

In the present application, an electronic device matched with a first touch pen is referred to as a first electronic device, and a touch pen matched with a second electronic device is referred to as a second touch pen.

S310, the second electronic device sends a second preset pressure threshold to the first stylus.

In this exemplary embodiment, after the second electronic device establishes a wireless connection with the first stylus, a second preset pressure threshold corresponding to the touch screen (i.e., the second touch screen) of the second electronic device may be sent to the first stylus. Therefore, the first touch pen can timely detect whether the writing pressure value exceeds the standard, the time delay for reminding the user of overlarge writing pressure is reduced, and the response speed for reminding the user of overlarge writing pressure is improved.

It should be understood that the second electronic device may also send the second preset pressure threshold to the first stylus at other times, for example, the second electronic device may send the second preset pressure threshold to the first stylus after receiving the second pressure value sent by the first stylus.

In one possible implementation, the second electronic device determines that the connected stylus is a new stylus (i.e., a stylus that has not been previously connected), and the second electronic device actively transmits a preset pressure threshold corresponding to its own touch screen to the second stylus.

In another possible implementation manner, when the first stylus determines that the connected electronic device is a new electronic device (i.e., an electronic device that has not been connected before, such as a second electronic device), the first stylus actively sends a request for acquiring a preset pressure threshold to the second electronic device, and the second electronic device sends the preset pressure threshold corresponding to its own touch screen to the first stylus in response to the request for acquiring the preset pressure threshold.

S311, the first touch pen stores a mapping relation between the second electronic equipment and a second preset pressure threshold value.

In an exemplary embodiment, after the first stylus receives the second preset pressure threshold sent by the second electronic device, a mapping relationship between the second preset pressure threshold and the second electronic device may be stored. In this way, when the first touch pen is connected with the second electronic device again, the first touch pen can directly read the second preset pressure threshold matched with the second electronic device from the local, and the second electronic device does not need to send the preset pressure threshold to the first touch pen every time the second electronic device is connected with the first touch pen. For example, after the first stylus establishes a wireless connection with the second electronic device, a preset pressure threshold value matched with the device information is locally queried from the first stylus based on the received device information of the second electronic device.

S312, after the first stylus enters a writing state, a second writing pressure value is acquired.

The writing state here is the second state of the claims, and the second writing pressure value here is the second pressure value of the claims.

S313, the first stylus sends a second writing pressure value to the second electronic device.

S314, the first stylus judges whether the second writing pressure value is larger than or equal to a second preset pressure threshold value; if yes, then execute S315; if not, ending the current flow.

S315, the first touch pen outputs a third prompt signal.

Optionally, the second electronic device in the present embodiment may further perform the following steps S314 to S316.

S316, the second electronic device judges whether the second writing pressure value is greater than or equal to a second preset pressure threshold value; if yes, then S317 is performed; if not, S318 is performed.

And S317, the second electronic device executes at least one of displaying the prompt popup and outputting other prompt signals.

And S318, the second electronic device responds to the operation of the first touch pen on the second touch screen.

In this embodiment, if the second electronic device determines that the second writing pressure value is not greater than the second preset pressure threshold, the second electronic device directly responds to the operation of the first touch screen, for example, the operation of drawing handwriting is performed.

In this embodiment, steps S316 to S318 are not necessarily executed either, that is, when the stylus detects that the writing pressure value exceeds the standard, a prompt signal is output, and the electronic device side interacting with the stylus does not need to repeatedly detect and prompt.

The processing method for touch pen operation provided by the embodiment is suitable for a scene that a touch pen is used across devices and is provided with a feedback device, after the second electronic device establishes wireless connection with the first touch pen, the second electronic device can send a preset pressure threshold corresponding to the touch screen to the first touch pen, after the writing pressure value acquired by the first touch pen is compared with the preset pressure threshold sent by the second electronic device, and if the writing pressure value is greater than or equal to the preset pressure threshold, the feedback device of the first touch pen is controlled to output a prompt signal. Therefore, the transmission time for transmitting the writing pressure value to the electronic equipment is saved, so that the time delay for reminding the excessive writing pressure is reduced, namely the response speed for reminding the excessive writing pressure is improved. Moreover, the prompt signal is directly output by the feedback device of the touch control pen, so that a user can directly perceive the feedback of the touch control pen, and the user experience is improved.

Further, the second electronic device may also continue to execute the process of judging whether the writing pressure value exceeds the standard, and outputting the prompting signal if the writing pressure value exceeds the standard, that is, if the writing pressure of the stylus exceeds the standard, both the stylus and the electronic device output corresponding prompting signals, and both the stylus and the electronic device output prompting signals, so that the validity of the prompting signals may be improved.
