The stylus 100 and the electronic device 200 may be interconnected by a communication network to implement interaction of wireless signals.

Fig. 2 is a schematic diagram of another scenario, referring to fig. 2, in which a stylus (stylus) 100, an electronic device 200, and a wireless keyboard 300 are included, to which embodiments of the present application are applicable. An electronic device 200 is illustrated in fig. 2 as a tablet computer (tablet). The stylus 100 and the wireless keyboard 300 may provide input to the electronic device 200, and the electronic device 200 performs an operation responsive to the input based on the input of the stylus 100 or the wireless keyboard 300.

Further, in the embodiment of the present application, the stylus 100 may be a capacitive pen, and the capacitive pen 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.

The active capacitive pen is generally internally provided with a battery and a chip, and the chip is used for transmitting a high-voltage signal to excite the capacitive screen (namely, the touch screen) to calculate related coordinates, and the strength of a user when using the capacitive pen can be measured so as to realize handwriting recognition. 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. Referring to fig. 2, when the stylus 100 is an active capacitive pen, an integrated electrode array is required on the touch screen 201 of the electronic device 200 that interacts with the stylus 100. In one embodiment, the electrode array may be a capacitive electrode array. The electronic device 200 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 201 when the signal is received. In the embodiment of the present application, the display screen in the electronic device 200 may also be referred to as a touch screen 201, and the stylus 100 may be referred to as a handwriting pen.

Referring to fig. 3, the stylus 100 may include a nib 10, a pen shaft 20, and a main circuit board (not shown) which may be disposed in the pen shaft 20 for a stylus with a replaceable nib. The pen holder 20 is hollow, the pen point 10 and the pen holder 20 can be connected in a plugging or clamping mode, or can be connected in a threaded mode, and the embodiment of the application is not limited to the above.

Among them, for convenience of the following description, the electrode TX may be referred to as a nib electrode and the electrode RX may be referred to as a cartridge electrode. Of course, the application is not limited herein to the number of electrodes in stylus 100.

The current stylus pen is worn along with the use of a user in the use process, the use of the user is influenced after the wear is to a certain extent, then the user needs to replace a new pen point, but the user can generally judge whether the pen point needs to be replaced or not according to the use condition of the user, and the writing experience of the user can not be influenced due to the fact that the replacement is possibly caused.

Fig. 4 is a flowchart of a method for prompting the pen tip lifetime of a stylus according to an embodiment of the present application, where the method is described with an electronic device as an execution body, and referring to fig. 4, the method includes:

S101, acquiring accumulated use time of the pen point of the connected touch pen.

S102, determining whether a prompt condition is met according to the accumulated pen point using time and a preset using threshold.

After the touch pen and the electronic device are interconnected through the communication network, the electronic device can acquire the accumulated use duration of the pen point of the connected touch pen, and in a specific implementation process, the information sent by the touch pen can be actively read or passively received.

In the active reading mode, optionally, the electronic device may send a nib accumulated use time length acquisition request to the stylus periodically or after connection is established with the stylus each time, and the stylus may send the nib accumulated use time length of the connected nib recorded and stored in the stylus to the electronic device after receiving the nib accumulated use time length acquisition request sent by the connected electronic device.

In the passive receiving mode, optionally, after the stylus establishes connection with the electronic device each time, or periodically, the electronic device actively sends the accumulated use duration of the pen point of the connected pen point recorded and stored in the stylus to the electronic device, and then the electronic device can passively receive the accumulated use duration of the pen point of the connected pen point sent by the stylus.

Of course, after the stylus and the electronic device are connected each time, the stylus can record and save the code printing time each time, when the connection is built again with the electronic device next time, the last code printing time of the connected pen point can be sent to the electronic device, and after the electronic device receives the writing time of the pen point sent by the stylus, the electronic device side records and saves the time.

After the electronic equipment obtains the accumulated use time of the pen point, whether the prompting condition of the service life of the pen point is met can be determined according to the accumulated use time of the pen point and a preset use threshold. The preset threshold value may be set according to a test lifetime value of the pen tip, and is used to indicate a cumulative service lifetime threshold value of the pen tip when the service lifetime of the pen tip reaches a preset lifetime critical point, and may be stored in the electronic device in advance or read from the pen tip, which is not limited herein. Alternatively, in particular, when determining whether the tip life prompting condition is met, the determination may be made according to a difference between the preset usage threshold and the cumulative pen tip usage time period, for example, when the difference between the preset usage threshold and the cumulative pen tip usage time period is smaller than the preset prompting difference, the tip life prompting condition may be considered to be met, or else the tip life prompting condition may be considered to be not met. Optionally, the preset prompt difference value may be any value such as 5 hours, 8 hours, 10 hours, etc., which is not limited herein, and may be flexibly adjusted according to an actual application scenario. Of course, according to the actual application scenario, it may also be determined whether the cumulative usage time length of the pen tip is equal to the preset usage threshold, if so, the indication condition of the pen tip lifetime may be considered to be satisfied, or else, the indication condition may be considered to be unsatisfied.

And S103, if the prompt condition is met, generating and displaying pen point service life prompt information.

If the tip life prompting condition is met, the tip service time of the stylus is long, and the stylus is close to the life critical value, tip life prompting information can be generated and displayed at the moment, and it can be understood that the user can replace the tip of the stylus in time through the displayed tip life prompting information, so that the fact that the user cannot know the tip of the stylus in time when the tip of the stylus reaches the life critical point is avoided, and the writing efficiency and writing effect of the user are affected.

Alternatively, the tip life prompting information may include, but is not limited to: the identification of the pen tip, the type of the pen tip, the accumulated use time of the pen tip, the expected sustainable writing time, the identification of the electronic device connected with the history, and the like are not limited herein, and can be flexibly set according to actual application scenes.

In this embodiment, by reading the accumulated use duration of the pen point of the connected stylus, determining whether the prompting condition is satisfied according to the accumulated use duration and the preset use threshold, and if the prompting condition is satisfied, generating and displaying the pen point life prompting information, the user can be reminded of replacing the pen point in time according to the pen point life prompting information in the use process of the stylus, the writing efficiency and the writing effect of the user are ensured, and the user experience can be effectively promoted.

Fig. 5 is a tip life prompting interface of a stylus according to an embodiment of the present application, and fig. 6 is a tip life prompting interface of another stylus according to an embodiment of the present application.

Optionally, the generated pen tip life prompting information may be displayed in a prompting window mode, or jump to a touch pen application program, and be displayed by the touch pen application program, and the present application is not limited to a specific display mode.

If the pen point life prompting information includes "expected sustainable writing time", the expected sustainable writing time can be obtained by calculating according to the accumulated pen point using time and a preset using threshold value in specific calculation, namely, the remaining available time is estimated.

In some embodiments, the prompt window is displayed in the form of a prompt window, and when the prompt condition is met, the prompt window is generated and displayed on the current interface, and referring to fig. 5, the prompt window 203 may be displayed on any current interface of the electronic device (for example, the prompt window may be popped up and displayed in an overlapping manner on the current interface). For example, the content displayed in the prompt window 203 may be preset text content, for example: "it is expected that the stylus tip BJA _001 can write for 2 hours, please replace the tip in time-! Optionally, in order to facilitate the user to intuitively know the type of the pen tip, the preset number of bits in the pen tip identifier may be used to indicate the type of the pen tip, the other number of bits is the serial number of the pen tip, and the serial number of the pen tip may uniquely identify the pen tip, which is not limited to the current practical identification mode. Referring to fig. 5, the third bit (i.e., a) in the pen tip identifier may be used to indicate the pen tip type, that is, it can be seen from the pen tip identifier that the pen tip belongs to the pen tip type a, alternatively, the type a may indicate that the pen tip is a conductive soft rubber type pen tip, and of course, besides the type a, the actual application scenario may further include the type B, and the type B may indicate that the pen tip is a soft plastic type pen tip, which is not limited to the specific classification and the identification manner. In addition, the content displayed in the prompt window 203 may also include a voice broadcast, a preset animation, etc., which is not limited herein. The 'continuous writing for 2 hours' is taken as the expected sustainable writing time, and can be determined according to the accumulated using time of the nib and the corresponding preset using threshold value of the nib, and when the actual determination is carried out, the accumulated using time of the nib can be subtracted from the corresponding preset using threshold value of the nib, so that the remaining sustainable writing time of the nib is obtained.

Referring to fig. 5 for the example of the tip BJA _001 of the stylus pen, if the electronic device reads that the cumulative usage duration of the tip BJA _001 is 98 hours and the corresponding preset usage threshold of the tip BJA _001 is 100 hours, and the preset indication difference is 2.5 hours, it can be calculated that the tip BJA _001 can last writing for 2 hours (100 hours-98 hours=2 hours), and it can be seen that the calculated expected sustainable writing time (2 hours) of the tip is less than the preset indication difference (2.5 hours), in this case, "the expected stylus tip BJA _001 can last writing for 2 hours, please replace the tip in time-! "tip life prompt information so that the user can change in time according to the tip life prompt information. Wherein different types of nibs can correspond to different preset use thresholds.

Alternatively, the current interface may be a main interface of the electronic device, or may be a use interface of any application program, which is not limited herein.

In some embodiments, when the information is displayed by the stylus application, that is, the corresponding management application may be downloaded and installed for the stylus, the application records information related to the stylus, and completes pushing of the prompt information, etc. Referring to fig. 6, the information management interface 204 preset in the stylus application program may be displayed, specifically, the management account corresponding to the stylus may be logged in through the stylus application program, as can be seen from fig. 6, the management account in the information management interface 204 may be a user mobile phone number: 131XXXX001, in which stylus-related management information may be displayed in the information management interface 204, may include, but is not limited to: the method comprises the steps of identifying a touch pen, identifying historical connected electronic equipment, electric quantity information of the touch pen, type of a connectable nib of the touch pen, identifying a nib currently connected with the touch pen, accumulated use time of the connected nib, expected sustainable writing time of the connected nib and the like. Of course, the specific display content is not limited to this, and may further include, according to an actual application scenario: information such as the connectable mode of the stylus and the electronic equipment. The expected sustainable writing time of the connected pen point can be referred to the relevant parts, and the application is not repeated here.

In addition, if the user has multiple touch pens, a corresponding management account may be established for each touch pen, and the management account corresponding to the touch pen may be a touch pen identifier, a brand model, or the like, which is not limited herein. In some embodiments, since the pen tip in the stylus is replaceable, optionally, the stylus identifier may be a pen holder identifier, and the pen holder identifier may be a production serial number corresponding to the pen holder, or may be composed of the pen tip identifier and the pen holder identifier, which is not limited herein. Based on this explanation, it can be seen from fig. 6 that the stylus history connects two electronic devices, pad_01 and pad_02, respectively, the current power of the stylus is 83%, the connection of type a and type B nibs can be supported, the currently connected nib is type a, the nib is identified as BJA _001, the current cumulative duration of use of the nib BJA _001 is 98 hours, and the expected usable duration is 2 hours. The accumulated use time period may be a sum of use times of the electronic device connected by the history.

Fig. 7 is an interaction schematic diagram of another method for prompting pen tip life of a touch pen according to an embodiment of the present application, and referring to fig. 7, the step of reading the accumulated use duration of the pen tip of the connected touch pen may include:

S201, the stylus acquires each coding time of the pen point and sends the each coding time to the electronic equipment.

S202, the electronic equipment receives each coding time of the pen point sent by the touch pen, and calculates and records the accumulated use time of the pen point of the touch pen according to each coding time of the pen point.

In some embodiments, each time the pen tip is coded, i.e., each time the pen tip is written, where each time the pen tip is coded may refer to a continuous writing time of the pen tip during each connection and disconnection of the stylus from the electronic device.

Optionally, the stylus may obtain the time of each code of the pen tip by: the pressure sensor can be arranged in the touch pen, the pressure sensor can be a strain type pressure sensor, strain materials in the strain type pressure sensor can deform in the writing process of the touch pen, the deformation of the strain materials can be transmitted to the main circuit board (for example, the strain type pressure sensor and the main circuit board can be electrically connected through a wire or a flexible circuit board), the main circuit board can detect the pressure of the writing end of the pen point according to the deformation of the strain materials, and accordingly the coding time of the pen point can be obtained according to the duration time of the pressure.

After the stylus acquires each code printing time of the pen point, the code printing time of each time can be sent to the electronic equipment, and after the electronic equipment receives each code printing time of the pen point sent by the stylus, the received code printing time of the pen point can be calculated and summed, so that the accumulated use duration of the pen point of the stylus is acquired.

In an alternative embodiment, in the writing process of the stylus, the thickness of the line at the writing end can also be controlled according to the pressure of the writing end of the stylus, wherein the greater the pressure is, the thicker the line at the writing end will be, and the smaller the pressure is, the thinner the line at the writing end will be.

It should be noted that, in some embodiments, the pressure sensor may also be: the piezoresistive pressure sensor, the ceramic pressure sensor, the diffused silicon pressure sensor and the like are not limited herein, and can be flexibly arranged according to actual application scenes. Referring to fig. 3, in which the pressure sensor may be provided in the nib 10 or the shaft 20 of the stylus 100, the present application is not limited to a specific location. Optionally, when the pressure sensor is disposed in the pen holder 20 of the stylus 100, after one end (i.e. writing end) of the nib 10 of the stylus 100 is stressed, the other end of the nib 10 moves to apply a force to the pressure sensor, and at this time, the stylus can acquire the code printing time of the nib each time through the pressure acquired by the pressure sensor. Of course, the detection mode for detecting the pressure applied to the writing end of the stylus is not limited thereto.

In another embodiment of transmitting the code printing time, considering that if the stylus is configured to send each code printing time to the electronic device in real time, the power consumption of the stylus may increase, in some embodiments, the stylus may send each code printing time of a pen point in the stylus in a first preset period (for example, 0.5 hour, 2 hours, etc.) to the electronic device according to the first preset period, after the electronic device receives each code printing time of a pen point in the stylus in each first preset period, the electronic device may correspondingly store according to the pen point identifier, and perform summation calculation to obtain the accumulated use time of the pen point of the stylus, which may reduce the number of times of sending the code printing time of the stylus, and effectively reduce the power consumption of the stylus. The stylus may send the code time of the pen point in the stylus in each first preset period to the electronic device directly or indirectly.

In another embodiment, the stylus may also send the coding time of the present use to the electronic device after the user finishes each use, for example, after the user stops using the stylus for longer than a preset time period (1 minute or 5 minutes).

Referring to fig. 2, the indirect transmission, that is, the stylus needs to transmit the recorded accumulated usage time of the pen tip to other external devices (for example, the wireless keyboard 300, the pen container 400, the pen holder, etc.), and then forward the recorded coding time to the electronic device through the connection between the other external devices and the electronic device; the recorded coding time is directly transmitted to the electronic device, namely, the stylus does not pass through other external devices, but directly according to a communication link between the stylus and the electronic device.

Optionally, if the stylus has a function of calculating and recording the accumulated usage time of the pen tip, the stylus can calculate and record the accumulated usage time of the pen tip according to each coding time of the pen tip, and send the recorded accumulated usage time of the pen tip to the electronic device. Optionally, when the stylus sends the recorded accumulated usage time of the pen tip to the electronic device, the sending may be direct sending or indirect sending, similarly, referring to fig. 2, the indirect sending, that is, the stylus needs to send the recorded accumulated usage time of the pen tip to other external devices (such as the wireless keyboard 300, the pen container 400, the pen holder, etc.), and then forward the recorded accumulated usage time of the pen tip to the electronic device through the connection between the other external devices and the electronic device; the recorded accumulated pen point use duration is directly sent to the electronic equipment not through other external equipment, but directly according to the communication connection between the stylus and the electronic equipment. In addition, the application is not limited to the sending timing of the stylus, and the stylus may be actively sent each time a communication connection is established with the electronic device, or the recorded nib accumulated duration may be periodically and actively sent to the electronic device according to a second preset period (for example, 2 hours, 4 hours, etc.), or the stylus may be passively sent according to a nib accumulated use duration acquisition request sent by a user, alternatively, the user may send the nib accumulated use duration acquisition request to the stylus through a stylus application program on the electronic device, where the stylus sending the nib accumulated use duration acquisition request may include: stylus identification, pen tip identification, etc.

In summary, the embodiment of the application is not limited to a sending mode and a sending time of sending the recorded accumulated use duration of the pen point to the electronic device by the touch pen, and can be flexibly set according to actual application scenes. Based on the above description, it can be understood that if the recorded cumulative use time of the pen tip is sent to the electronic device by the stylus, it can be avoided that each electronic device can only record the cumulative use time of the pen tip of the stylus on the electronic device when the same stylus is used on different electronic devices, so that the final obtained cumulative use time of the pen tip of the stylus is not accurate enough, that is, by applying the method of the embodiment of the present application, the more accurate cumulative use time of the pen tip of the stylus can be obtained.

Based on the above description, in some embodiments, considering that the user may use the same stylus to use the same stylus on different electronic devices, optionally, the electronic device may send the latest calculated accumulated usage time of the nib to the stylus according to a third preset period (for example, 1 hour, 3 hours, etc.), so that when the stylus is in communication connection with other electronic devices, the stylus may synchronously forward the latest accumulated usage time of the nib sent by the previous electronic device to the other electronic devices, and accordingly, the other electronic devices may obtain the latest accumulated usage time of the nib, and further, when continuing to accumulate based on the latest accumulated usage time of the nib, the more accurate accumulated usage time of the nib of the stylus may be obtained.

In addition, in some embodiments, if the user can log in the management account corresponding to the stylus through the electronic device, the electronic device can update the latest calculated accumulated use time length of the pen point to the management account corresponding to the stylus in real time, so that the user can be ensured to synchronously acquire the latest accumulated use time length of the pen point in real time by logging in the management account corresponding to the stylus on each electronic device when using the same stylus on different electronic devices.

Moreover, considering that the pressure of writing by different users by using the touch pen is different, for example, the pressing force is lighter when some users use the touch pen to write, or the pressing force is heavier, wherein if the pressing force of a certain user when using the touch pen to write is lower than the preset pressing force range, the pressing force of the certain user can be considered lighter; otherwise, if the pressing force is higher than the preset average pressing force, the pressing force of the user may be considered to be heavier, or alternatively, the preset pressing force range may be a preset average pressing force range, which may be obtained by counting the pressing forces of a plurality of users when writing with the stylus, or may be set according to the considered experience, which is not limited herein.

Based on this description, it can be understood that, because the pressures of writing with the stylus by different users are different, for example, if the pressing force is lighter when a user writes with the stylus, even if the accumulated use time of the nib of the stylus used by the user is read to be longer than the preset use threshold, the nib wear of the stylus is not serious in practice, that is, the nib of the stylus does not reach the nib life critical point, or if the pressing force is heavier when a user writes with the stylus, although the accumulated use time of the nib of the stylus used by the user is read to be shorter than the preset use threshold at a certain moment, the nib wear of the stylus is serious in practice, that is, the nib of the stylus reaches the nib life critical point earlier than the prompt time of the prompt information, in order to prompt the user better and more accurately, the judgment condition is increased before judging whether the prompt condition is satisfied.

Fig. 8 is a flow chart of another method for prompting the pen tip lifetime of a stylus according to an embodiment of the present application, in this embodiment, based on the fact that during the writing process of the stylus, the pen tip electrode may be used to emit an electrode signal, and when the pen tip electrode approaches the touch screen of the electronic device, a coupling capacitor may be formed between the pen tip electrode and the touch screen of the electronic device, so that the electronic device may receive the electrode signal. Referring to fig. 8, in the method, before reading the accumulated usage time of the pen tip of the connected stylus may include:

S301, detecting and acquiring an electrode signal generated according to a pen tip electrode of the stylus.

S302, if the signal quantity of the electrode signal generated by the pen point electrode of the touch pen is larger than a first threshold value, reading the accumulated use duration of the pen point of the connected touch pen.

S303, determining whether a prompt condition is met according to the accumulated use duration of the pen point and a preset use threshold, and if the prompt condition is met, generating and displaying pen point service life prompt information.

When the electronic device obtains an electrode signal generated by an electrode of a nib of the touch pen, it can be judged whether the signal quantity of the electrode signal is larger than a first threshold value, if so, the abrasion quantity of the nib of the touch pen reaches the abrasion quantity corresponding to the nib life critical point, that is, the nib abrasion of the touch pen is serious, the accumulated use duration of the nib of the connected touch pen can be read at the moment, further, whether the accumulated use duration of the nib is larger than a preset use threshold value is judged, if so, the accumulated use duration of the nib of the touch pen also reaches the accumulated use duration threshold value of the nib corresponding to the nib life critical point, and it can be understood that under the condition, the nib of the touch pen reaches the nib life critical point from the two dimensions of the abrasion quantity and the nib accumulated use duration, and the generated nib life prompt information has the characteristic of prompting accuracy, so that the user can be reminded of timely replacement when the nib reaches the nib life critical point, and the writing experience of the user is improved.

The first threshold may represent a signal amount threshold corresponding to an electrode signal generated by a pen tip electrode of the stylus when a pen tip abrasion amount of the stylus reaches an abrasion amount corresponding to a pen tip lifetime critical point. Alternatively, the wear amount corresponding to the nib life critical point may be any value from 1/4 to 1/3 of the size (e.g., diameter, area, etc.) of the reference nib, and for example, the wear amount corresponding to the nib life critical point of a nib of a certain type is 1/3 of the diameter of the reference nib of that type, then the first threshold corresponding to the nib of that type is a threshold corresponding to the signal amount corresponding to the electrode signal generated by the reference nib electrode when the diameter of the reference nib is 2/3 (wherein 1/3 of the diameter of the reference nib is worn), wherein the reference nib is an unused, completely new nib. Wherein, the more serious the nib wear of the stylus, the larger the signal quantity of the electrode signal generated by the nib electrode of the stylus will be, otherwise, the smaller the signal quantity of the electrode signal generated by the nib electrode of the stylus will be. Of course, the correspondence between the signal amount of the electrode signal generated by the stylus tip electrode and the wear degree of the stylus tip is not limited thereto. Alternatively, the signal quantity of the electrode signal can be acquired through an analog-to-digital converter (Analog to Digital Converter, ADC) built in the electronic device.

For example, if the first threshold is a, and the electrode signal generated by the nib electrode of the stylus pen is B, if the value of a is 4000, it can be seen that, when the value of B is 4800, the signal amount (i.e. 4800) of the electrode signal generated by the nib electrode of the stylus pen is larger than the first threshold (i.e. 4000), in this case, the electronic device can read the accumulated pen tip usage time period of the connected stylus pen, where if the accumulated pen tip usage time period of the electronic device read the pen tip at a certain time is 50 hours, and the preset usage threshold corresponding to the pen tip is 100 hours, and the preset prompt difference is 2.5 hours, then it can be seen that the predicted sustainable writing time of the pen tip is 50 hours (100 hours-50 hours=50 hours), and the predicted sustainable writing time of the calculated pen tip is larger than the preset prompt difference (2.5 hours), so that the electronic device does not satisfy the prompt condition, and the electronic device can not display life prompt information, and avoid the invalid prompt information of the pen tip to the user; if the accumulated pen point using time of the pen point read by the electronic device at the other moment is 98 hours, it can be seen that the calculated expected sustainable writing time (2 hours=100 hours-98 hours) of the pen point is smaller than the preset prompt difference (2.5 hours) and meets the prompt condition, and then the pen point life prompt information can be generated and displayed. The values of a and B are not limited to the above examples, and may be flexibly set according to the actual application scenario and the type of the pen tip.

Fig. 9 is a schematic diagram illustrating replacement of a pen tip of a stylus according to an embodiment of the present application. The application is not limited to the type of nib 10 in the stylus 100, and alternatively, referring to fig. 9, the same pen holder may be connected to different types of nibs, for example, may be connected to a conductive soft rubber type nib 11, or may be connected to a softer plastic type nib 12, which is not limited herein, and may be flexibly replaced according to practical application scenarios. Of course, it should be noted that different types of nibs can correspond to different nib type identifications, so that after the user replaces the nib type identifications, the electronic device can acquire the nib type identifications after being in communication connection with the touch pen, namely, the user can be recorded and prompted to replace another type of nib, the writing mode is adjusted, and the use experience of the user is improved.

In an alternative embodiment, for the scene that the same pen holder can be connected with different types of nibs, after the electronic device is in communication connection with the touch pen, a nib type acquisition request can be sent to the touch pen, after the touch pen receives the nib type acquisition request sent by the electronic device, the nib type identification can be fed back to the electronic device, after the electronic device receives the nib type identification, the corresponding first threshold value, the preset use threshold value and other related parameters can be acquired according to the preset mapping relation, so that the electronic device can generate more accurate nib life prompting information, and the user is prevented from being reminded by mistake, and the use experience of the user is influenced. Of course, after replacing the pen tip, the user may update the information of the pen tip (for example, the type of the pen tip, the first threshold value corresponding to the pen tip, and the preset use threshold value) in the touch pen information recorded by the electronic device independently, which is not limited herein.

The preset mapping relation comprises the following steps: the pen point type marks respectively correspond to a first threshold value and a preset use threshold value. Optionally, the preset mapping relationship may be obtained through a stylus application, where the preset mapping relationship in the stylus application may be imported by an application manager, or may be obtained through a cloud, and of course, the specific obtaining mode is not limited thereto.

In another alternative embodiment, multiple pen point type identifiers may be stored in the electronic device, if the electronic device determines that the user replaces the pen point, a pen point type selection interface may be displayed, where the pen point type selection interface may include multiple pen point type identifiers, and at this time, the user may select the pen point type identifier corresponding to the replaced pen point based on the touch screen of the electronic device through clicking, sliding, dragging, long pressing, and other touch modes, so that the electronic device may accurately obtain the type of the replaced pen point. Of course, in some embodiments, after the user replaces the nib, the nib type identifier of the replaced nib may also be manually edited, for example, if the electronic device determines that the user replaces the nib, a nib type editing interface may be displayed, where the user may manually edit the nib type identifier corresponding to the replaced nib, optionally, during specific editing, editing may be performed according to the nib type identifier on the stylus, which is not limited herein.

In an alternative embodiment, if the connection mode of the pen tip and the pen holder is different, the stylus may determine the type of the connected pen tip by referring to the following manner, where the stylus may determine whether the type of the pen tip is changed by comparing the current connection mode of the pen tip and the pen holder with the previous connection mode. Optionally, if the connection mode of the plastic nib with the softer material and the pen holder is a threaded connection mode, and the connection mode of the conductive soft rubber nib and the pen holder is a clamping connection mode, the pen holder can detect the connection mode with the nib through the related sensors (such as an optical sensor, a pressure sensor, etc.) in the pen holder, so as to further determine the nib type identifier corresponding to the nib, and the determined nib type identifier can be sent to the electronic device. It will be appreciated that if the pen shaft detects that the current nib is connected (screwed) differently from the previous nib (snapped), the user may consider that the current nib is of a different type from the previous nib. Currently, the specific recognition method of the pen tip type is not limited to the above description.

Further, it may be understood that if the user refers to the tip life prompt information to replace the tip, then the tip in the stylus is a new tip, in which case, in order to facilitate the electronic device to determine and record that the stylus has replaced the tip and to accurately record the cumulative usage time of the tip of the new tip, the stylus may optionally send a tip replacement message to the electronic device, optionally the tip replacement message may include a tip type identifier, a tip replacement time, etc., and at this time, the electronic device may determine and record that the tip has been replaced after receiving the tip replacement message. In some embodiments, if the stylus further includes a button that may be electrically connected to the main circuit board (e.g., via a wire or flexible circuit board), the button may optionally be configured to send a tip replacement message to the electronic device in response to a control operation (e.g., a pressing operation, a toggle operation) by the user.

Fig. 10 is a schematic diagram of tip replacement prompt of a stylus according to an embodiment of the present application. In this embodiment, based on the situation that the more the pen tip of the stylus is worn, the greater the signal amount of the electrode signal generated by the pen tip electrode of the stylus will be, the electronic device may detect the signal amount of the electrode signal generated by the pen tip electrode of the stylus, and determine whether the stylus tip is replaced according to the detected signal amount of the electrode signal and the signal amount of the electrode signal detected last time.

If the detected signal quantity of the electrode signal is smaller than the signal quantity of the electrode signal detected in the previous time, the abrasion degree of the pen point is changed, and the user is determined to replace the pen point.

In view of the fact that the signal amount of the electrode signal detected by the electronic device is affected by the writing manner, the writing environment, and the like, there may be a case where the user does not change the pen point, but the signal amount of the detected electrode signal is smaller than the signal amount of the electrode signal detected in the previous time, in which case, in order to avoid the influence of the unnecessary change prompt window on the writing process of the user, the change prompt window may be displayed when the signal amount of the detected electrode signal is smaller than the signal amount of the electrode signal detected in the previous time and the difference therebetween satisfies the preset condition, and it is understood that the change prompt window displayed at this time has the characteristic of accurate prompt. Alternatively, the preset condition may be a preset difference value, which may be set according to human experience, which is not limited herein.

As shown in fig. 10, a replacement prompt window 205 may be displayed, where the replacement prompt window 205 may include a determination control 2051, for example in fig. 10, where the replacement prompt window 205 is used to allow the user to further confirm whether the nib BJA _001 in the stylus bg_001 has been replaced with bjb_004, and at this time, if the nib is replaced, the user may determine and record the replacement nib based on the touch screen of the electronic device by clicking, long pressing, sliding, re-pressing, and the like, on the determination control 2051 to generate a determination operation for the determination control 2051, and in response to the determination operation, the electronic device 200 may determine and record the replacement nib.

It will be appreciated that if the electronic device determines that a new nib has been replaced, i.e. the electronic device determines that a new nib has been replaced, the accumulated length of nib use for the new nib may be re-recorded.

If the replaced new pen point is the same as the previous pen point in type, for example, the pen points are all conductive soft rubber type pen points, the accumulated use time of the pen points corresponding to the previous pen point can be cleared to zero for realizing updating; alternatively, if each nib has a corresponding nib identifier and a different nib type has a corresponding nib type identifier, after optionally replacing a new nib, the electronic device may record the accumulated use duration of the nib corresponding to the new nib according to the nib identifier of the new nib and the nib type identifier.

Fig. 11 is a schematic diagram illustrating details of nib replacement of a stylus according to an embodiment of the present application. Further, after the electronic device 200 determines to replace the pen tip, in order to facilitate the user's knowledge of the new pen tip, the electronic device may display replacement hint information after determining and recording the replacement pen tip, which may include, but is not limited to: the identification of the new nib, the identification of the type of the new nib, the attribute parameters of the new nib, etc. Wherein, the attribute parameters of the new pen tip may include: brand information, expected usable time information, replacement time information, usage instruction information, and the like are not limited herein, and may be flexibly set according to actual application scenarios. Alternatively, the replacement prompt information may be displayed in the form of a prompt window, as shown in fig. 11, a nib replacement detail window 206 may be displayed, or the user jumps to a stylus application program, and the specific display manner may be referred to the display manner of the nib life prompt information, which is not described herein.

As can be seen from fig. 11, the nib replacement detail window 206 may display preset text content, for example, prompt the user to replace the nib of the touch pen bg_001 20 minutes at 10 days of 10 months of 2021, and the replaced nib is bjb_004, and the replaced nib is expected to be continuously used for 100 hours, and it should be noted that, according to the actual application scenario, the nib replacement detail window 206 may also display related information of the nib before replacement, which may include but is not limited to: the pen point mark before replacement, the accumulated use time of the pen point before replacement, etc.

Based on the foregoing, when the stylus is used as the execution subject, the pressure of the writing end of the pen tip 10 can be detected by the pressure sensor during the writing of the stylus, so that the coding time of the pen tip can be obtained according to the duration of the pressure.

Optionally, according to each coding time of the pen tip, the stylus may calculate and record the accumulated pen tip usage time, and send the recorded accumulated pen tip usage time to the electronic device 200; alternatively, the obtained code printing time may be sent to the electronic device 200 by the stylus according to a first preset period (for example, 0.5 hour, 2 hours, etc.), optionally, after the received code printing time of the pen tip of the stylus in each first preset period, the electronic device 200 may correspondingly store the code printing time according to the identification of the pen tip in the stylus, and perform summation calculation to obtain the accumulated use duration of the pen tip of the stylus.

It should be noted that, the connection manner of the stylus and the electronic device may be a direct communication connection, for example, a WI-FI hot spot network, a WI-FI point-to-point (P2P) network, a bluetooth network, a zigbee network, or a Near Field Communication (NFC) network, which are described above, and other near field communication networks. In addition, the stylus can be in communication connection with external devices such as a pen holder, a pen container or a wireless keyboard, and the external devices are in communication connection with the electronic device to help the stylus to forward information.

Accordingly, when the stylus transmits the recorded accumulated usage time of the pen tip to the electronic device, the transmission may be direct transmission or indirect transmission, which is not limited herein, and the description of the portion may be referred to the related portion and the application is not repeated herein.

In addition, it should be noted that, in the embodiment of the present application, the relationship among the first preset period, the second preset period and the third preset period is not limited, and may be flexibly set according to an actual application scenario.

In some embodiments, considering that the storage space of the storage device in the stylus is limited, optionally, the stylus may clear the stored pen tip coding time and the accumulated pen tip using time when the stylus detects that the pen tip is replaced. In some application scenarios, in order to avoid zero clearing misoperation, the identification of the last pen point and the identification of the new pen point can be obtained, and whether stored pen point coding time and accumulated pen point using duration are cleared or not is determined by comparing whether the identifications of the last pen point and the new pen point are the same. If the two marks are different, the stored nib code time and nib accumulated use duration corresponding to the last nib are cleared, so that the corresponding nib code time and nib accumulated use duration of the new nib can be stored, related data loss is avoided, otherwise, the clearing operation is not required, and misoperation is avoided.

In an alternative embodiment, if the stylus detects a tip replacement operation, or receives a tip update message sent by the terminal, the stylus determines that the tip has been replaced. For this part, reference is made to the foregoing related description, and no further description is given here.

Fig. 12 is a schematic hardware structure of a stylus according to an embodiment of the present application. Referring to fig. 12, the stylus 100 may have a processor 110, and the processor 110 may include storage and processing circuitry for supporting operation of the stylus 100. The storage and processing circuitry may include storage devices such as non-volatile memory (e.g., flash memory or other electrically programmable read-only memory configured as a solid state drive), volatile memory (e.g., static or dynamic random access memory), and the like. Processing circuitry in the processor 110 may be used to control the operation of the stylus 100. The processing circuitry may be based on one or more microprocessors, microcontrollers, digital signal processors, baseband processors, power management units, audio chips, application specific integrated circuits, and the like.

One or more sensors may be included in the stylus 100. For example, pressure sensor 120, inertial sensor 130, etc., wherein inertial sensor 130 may include a three-axis accelerometer and a three-axis gyroscope, and/or other components for measuring movement of stylus 100, e.g., a three-axis magnetometer may be included in the sensor in a nine-axis inertial sensor configuration. The sensors may also include additional sensors such as temperature sensors, ambient light sensors, light-based proximity sensors, contact sensors, magnetic sensors, pressure sensors, and/or other sensors.

The buttons 150 may include mechanical buttons and non-mechanical buttons, and the buttons 150 may be used to collect button press information from a user.

In embodiments of the present application, the stylus 100 may include one or more electrodes, where one electrode may be located at the writing end of the stylus 100, and as shown above, the electrode TX may be located in the pen tip, and the electrode RX may be located in the pen shaft, as described above with reference to the related description.

A sensing circuit 170 may also be included in the stylus 100. The sensing circuit 170 may sense capacitive coupling between the electrodes 160 and drive lines of a capacitive touch sensor panel that interacts with the stylus pen 100. The sensing circuit 170 may include an amplifier to receive the capacitance readings from the capacitive touch sensor panel, a clock to generate a demodulation signal, a phase shifter to generate a phase shifted demodulation signal, a mixer to demodulate the capacitance readings using in-phase demodulation frequency components, a mixer to demodulate the capacitance readings using quadrature demodulation frequency components, and the like. The result of the mixer demodulation may be used to determine an amplitude proportional to the capacitance so that the stylus 100 may sense contact with the capacitive touch sensor panel.

It will be appreciated that the stylus 100 may include a microphone, speaker, audio generator, vibrator, camera, data port, display screen, and other devices, as desired. A user may control the operation of the stylus 100 and the electronic device 200 interacting with the stylus 100 by providing commands with these devices and receive status information and other outputs.

The processor 110 may be used to run software on the stylus 100 that controls the operation of the stylus 100. During operation of the stylus 100, software running on the processor 110 may process sensor inputs, button inputs, and inputs from other devices to monitor movement of the stylus 100 and other user inputs. Software running on the processor 110 may detect user commands and may communicate with the electronic device 200.

To support wireless communication of the stylus 100 with the electronic device 200, the stylus 100 may include a wireless module. In fig. 12, a bluetooth module 180 is taken as an example of the wireless module. The wireless module may also be a WI-FI hotspot module, a WI-FI point-to-point module, or the like. The bluetooth module 180 may include a radio frequency transceiver, such as a transceiver. Bluetooth module 180 may also include one or more antennas.

The stylus 100 may also include a charging module 190, and the charging module 190 may support charging of the stylus 100 to provide power to the stylus 100.

Fig. 13 is a schematic hardware structure of an electronic device according to an embodiment of the present application. Referring to fig. 13, the electronic device 200 may include multiple subsystems that cooperate to perform, coordinate, or monitor one or more operations or functions of the electronic device 200. Electronic device 200 includes processor 210, input surface 220, coordination engine 230, power subsystem 240, power connector 250, wireless interface 260, and display 270.

Illustratively, coordination engine 230 may be used to communicate and/or process data with other subsystems of electronic device 200; communication and/or transaction data with the stylus 100; measuring and/or obtaining an output of one or more analog or digital sensors (such as touch sensors); measuring and/or obtaining outputs of 1 or more sensor nodes of an array of sensor nodes (such as an array of capacitive sensing nodes); receiving and locating tip and ring signals from the stylus 100; the stylus 100 or the like is positioned based on the positions of the tip signal crossing region and the ring signal crossing region.

The coordination engine 230 of the electronic device 200 includes or is otherwise communicatively coupled to a sensor layer located below or integral with the input surface 220. The coordination engine 230 utilizes the sensor layer to locate the stylus 100 on the input surface 220 and uses the techniques herein to estimate the angular position of the stylus 100 relative to the plane of the input surface 220. In one embodiment, the input surface 220 may be referred to as a touch screen 201.

For example, the sensor layer of coordination engine 230 of electronic device 200 is a grid of capacitive sensing nodes arranged in columns and rows. More specifically, the array of column traces is arranged perpendicular to the array of row traces. The sensor layer may be separate from other layers of the electronic device, or the sensor layer may be disposed directly on another layer, such as but not limited to: display stack layers, force sensor layers, digitizer layers, polarizer layers, battery layers, structural or decorative housing layers, and the like.

The sensor layer can operate in a variety of modes. If operating in mutual capacitance mode, the column and row traces form a single capacitive sense node at each overlap point (e.g., a "vertical" mutual capacitance). If operating in self-capacitance mode, the column and row traces form two (vertically aligned) capacitive sense nodes at each overlap point. In another embodiment, if operating in a mutual capacitance mode, adjacent column traces and/or adjacent row traces may each form a single capacitive sense node (e.g., a "horizontal" mutual capacitance). As above, the sensor layer may detect the presence of the tip 10 of the stylus 100 and/or the touch of a user's finger by monitoring the capacitance (e.g., mutual capacitance or self capacitance) change presented at each capacitive sensing node. In many cases, coordination engine 230 may be configured to detect tip and ring signals received from stylus 100 through the sensor layer via capacitive coupling.

Wherein the tip signal and/or the ring signal may include specific information and/or data that may be configured to cause the electronic device 200 to identify the stylus 100. Such information is generally referred to herein as "stylus identity" information. This information and/or data may be received by the sensor layer and interpreted, decoded, and/or demodulated by coordination engine 230.

Processor 210 may use the stylus identity information to simultaneously receive input from more than one stylus. In particular, coordination engine 230 may be configured to communicate to processor 210 the position and/or angular position of each of the number of styluses detected by coordination engine 230, in other cases coordination engine 230 may also communicate to processor 210 information regarding the relative positions and/or relative angular positions of the plurality of styluses detected by coordination engine 230. For example, coordination engine 230 may notify processor 210 that the detected first stylus is located away from the detected second stylus.

In other cases, the end signal and/or ring signal may also include specific information and/or data for causing the electronic device 200 to identify a specific user. Such information is generally referred to herein as "user identity" information.

The coordination engine 230 may forward the user identity information (if detected and/or recoverable) to the processor 210, and if the user identity information cannot be recovered from the tip signal and/or the ring signal, the coordination engine 230 may optionally indicate to the processor 210 that the user identity information is not available. Processor 210 can utilize user identity information (or the absence of such information) in any suitable manner, including but not limited to: accepting or rejecting input from a particular user, allowing or rejecting access to a particular function of the electronic device, etc. Processor 210 may use the user identity information to simultaneously receive input from more than one user.

In still other cases, the tip signal and/or the ring signal may include specific information and/or data that may be configured to cause the electronic device 200 to identify settings or preferences of the user or the stylus 100. Such information is generally referred to herein as "stylus setup" information.

The coordination engine 230 may forward the stylus setting information (if detected and/or recoverable) to the processor 210, and if the stylus setting information cannot be recovered from the tip signal and/or the ring signal, the coordination engine 230 may optionally indicate to the processor 210 that the stylus setting information is not available.
