< method example >

Fig. 4 is a schematic flowchart of an angle information processing method according to an embodiment of the present invention.

Referring to fig. 4, the angle information processing method of the present embodiment is implemented by the electronic pen 1000, and may include the steps of:

in step S2100, the electronic pen 1000 obtains a current tilt angle at which the electronic pen 1000 is tilted with respect to a set reference direction.

In this embodiment, the set reference direction is an absolute direction. In practical applications, a desired reference direction may be set according to application needs, and here, one reference direction may be set, or at least two reference directions may be set.

In one example, one reference direction set is a vertical reference direction.

In this example, the electronic pen 1000 may obtain only a current tilt angle at which the electronic pen 1000 is tilted with respect to a vertical reference direction, and obtain a current tilt position of the electronic pen 1000 based on the current tilt angle.

In one example, the electronic pen sets at least two reference directions, which may include a vertical reference direction and at least one horizontal reference direction, for example, sets three reference directions, which are respectively a vertical reference direction Z and two horizontal reference directions X, Y, the three reference directions being orthogonal to each other to constitute a cartesian coordinate system.

In this example, the electronic pen 1000 may respectively obtain current tilt gears mapped to the current tilt angle corresponding to each of the at least two reference directions, and obtain the current tilt gear of the electronic pen 1000 according to the current tilt gears.

In the present embodiment, the electronic pen 1000 may detect the current tilt angle of the electronic pen 1000 with respect to a set reference direction by providing an angle measuring device 1030, which is, for example, an acceleration sensor.

For example, the acceleration sensor may be a three-axis acceleration sensor with which a current tilt angle of the electronic pen 1000 with respect to one or more of the vertical reference direction Z, the horizontal reference direction X, and the horizontal reference direction Y is detected.

In step S2200, the electronic pen 1000 obtains a current tilt gear of the electronic pen 1000 according to the current tilt angle.

In this embodiment, any manner may be adopted to set the inclined gear, as long as according to the agreement of the transmitting and receiving parties, the task item corresponding to the current inclined gear can be executed according to the obtained current inclined gear.

In one example, the obtaining, by the electronic pen 1000 in step S2200, a current tilt gear of the electronic pen 1000 according to the current tilt angle may include:

in step S2211, the electronic pen 1000 acquires mapping data indicating a mapping relationship between the tilt angle and the tilt gear.

The mapping data may be a look-up table, a mapping function, or the like, and is not limited herein.

In one example, one reference direction or at least two reference directions may be set, and the electronic pen stores mapping data corresponding to the reference directions one by one, that is, mapping data corresponding to each reference direction, wherein each mapping data reflects the mapping relationship between the inclination angle of the corresponding reference direction and the inclination indexing position of the corresponding reference direction.

In this example, taking the vertical reference direction as an example, the mapping data may be such that the tilt sub-steps are set according to the tilt angle range of the vertical reference direction, different tilt angle ranges corresponding to different tilt sub-steps, for example, the current tilt angle θ of the vertical reference direction_ZTheta is more than or equal to 60 degrees_ZWithin the range of not more than 90 degrees, corresponding to a vertical first gear, the current inclination angle theta_ZTheta is more than or equal to 30 DEG_ZLess than 60 degrees, corresponding to a vertical second gear and the current inclination angle theta_ZTheta is more than or equal to 0 DEG_ZAnd in the range of less than 30 degrees, the gear corresponds to a vertical third gear.

In this example, still taking the vertical reference direction as an example, on the basis of setting the tilt gear according to the tilt angle range of the vertical reference direction, the corresponding tilt gear may be set individually for some special tilt angles. For example, when the electronic pen 1000 is horizontally placed, its current tilt angle θ with respect to the vertical reference direction _ZIs 90 deg., at this time, the current inclination angle theta can be_Z90 ° for one gear, e.g. the vertical lowest gear; and the current inclination angle theta_ZAt theta_ZThe range < 90 ° corresponds to another gear or gears.

In this example, still taking the vertical reference direction as an example, the mapping data may be to incline the current tilt angle θ_ZAs an independent variable, the vertical gear P_ZMapping function P as a dependent variable_Z＝F(θ_Z)。

In one example, the electronic pen sets at least two reference directions, for example, the at least two reference directions include a vertical reference direction and at least one horizontal reference direction, and the electronic pen stores mapping data reflecting the correspondence between the tilt angles of all the reference directions and the tilt gear of the electronic pen 1000.

In this example, for example, the reference directions include a vertical reference direction Z and a horizontal reference direction Y, and the mapping data may be based on the range of inclination angles in the two reference directionsAnd (4) setting inclined gears, wherein different inclination angle ranges correspond to different inclined gears. For example, the current inclination angle θ of the vertical reference direction_ZAnd the current inclination angle theta of the horizontal reference direction_YTheta is respectively more than or equal to 60 degrees_Z≤90°,45°≤θ_YThe range of less than or equal to 135 degrees corresponds to the first gear of the right hand; current tilt angle θ _ZAnd the current inclination angle theta_YTheta is respectively more than or equal to 60 degrees_Z＜＝90°,-135°≤θ_YNot more than-45 degrees corresponding to the first gear of the left hand; current tilt angle θ_ZAnd the current tilt angle theta_YAre respectively more than or equal to theta at 30 degrees_Z＜60°,45°≤θ_YNot more than 135 degrees corresponding to the second gear of the right hand; current tilt angle θ_ZAnd the current tilt angle theta_YAre respectively more than or equal to theta at 30 degrees_Z＜60°,-135°≤θ_YNot more than-45 degrees corresponding to the second gear of the left hand; current tilt angle θ_ZAnd the current inclination angle theta_YTheta is respectively more than or equal to 0 degree_Z＜30°,45°≤θ_YIs less than or equal to 135 degrees and corresponds to the third gear of the right hand; current tilt angle θ_ZAnd the current tilt angle theta_YTheta is respectively more than or equal to 0 degree_Z＜30°,-135°≤θ_YIs less than or equal to minus 45 degrees and corresponds to the third gear of the left hand.

In this example, too, the corresponding tilt gear position may be set individually for a particular tilt angle. For example, when the electronic pen 1000 is horizontally placed, its current tilt angle θ with respect to the vertical reference direction_ZIs 90 deg., at this time, the current inclination angle theta can be_ZIs 90 DEG, the current inclination angle theta_YOne gear, for example, the vertically lowest gear, is assigned to any angle.

In this example, still taking the example that the at least two reference directions include the vertical reference direction Z and the horizontal reference direction Y, the mapping data may be such that the current tilt angle θ is inclined by_ZAnd the current inclination angle theta_YA mapping function P, which is an independent variable and has the tilt position P of the electronic pen 1000 as a dependent variable, is F (θ) _Z,θ_Y)。

In step S2212, the electronic pen 1000 obtains a current tilt gear mapped to the current tilt angle according to the mapping data and the current tilt angle.

In an example, the electronic pen 1000 may obtain a tilt angle range to which the current tilt angle belongs, and use a tilt gear corresponding to the tilt angle range to which the current tilt angle belongs as the current tilt gear of the electronic pen 1000.

In an example, the electronic pen 1000 may also compare a magnitude relationship between the current tilt angle and a specific tilt angle to obtain a comparison result, and determine the current tilt gear of the electronic pen 1000 according to the comparison result. The specific inclination angle is, for example, 90 ° inclined with respect to the vertical reference direction, but may be other inclination angles, and is not limited herein.

In one example, only one reference direction, for example, a vertical reference direction, is set, so the mapping data reflects a mapping relationship between the tilt angle of the reference direction and the tilt tap position of the reference direction, and the current tilt tap position determined according to the mapping data and the current tilt angle is the current tilt tap position of the electronic pen 1000.

In one example, at least two reference directions are set, wherein the at least two reference directions include at least two directions of a vertical reference direction Z, a horizontal reference direction X, and a horizontal reference direction Y.

In this example, in step S2200, obtaining the current tilt gear of the electronic pen 1000 according to the current tilt angle may further include: the current tilt gear of the current tilt angle mapped to each of the at least two reference directions is obtained, and the current tilt gear of the electronic pen 1000 is formed.

For example, the current tilt angle of the electronic pen 1000 may be expressed as: theta_t＝(θ_X,θ_Y,θ_Z) At this time, the current tilt gear of the electronic pen 1000 may be expressed as: p_t＝(P_X,P_Y,P_Z) Wherein, theta_X,θ_Y,θ_ZRespectively represents the current tilt angles, P, of the electronic pen 1000 at time t with respect to the horizontal reference direction X, the horizontal reference direction Y, and the vertical reference direction Z_X,P_Y,P_ZRespectively show an electronic pen 1000the time t is mapped to the current tilt tap position of the current tilt angle corresponding to each reference direction, and t is a timestamp corresponding to the current tilt angle of the electronic pen 1000.

For another example, the current tilt angle of the electronic pen 1000 may also be expressed as: theta_t＝(θ_X,θ_Z) At this time, the current tilt gear of the electronic pen 1000 may be expressed as: p_t＝(P_X,P_Z)。

For another example, the current tilt angle of the electronic pen 1000 may also be expressed as: theta_t＝(θ_Y,θ_Z) At this time, the current tilt gear of the electronic pen 1000 may be expressed as: p _t＝(P_Y,P_Z)。

In this example, in step S2200, the obtaining, by the electronic pen 1000 according to the current tilt angle, the current tilt gear of the electronic pen 1000 may further include: the current tilt gear mapped to the current tilt angles corresponding to all the reference directions is obtained, that is, the current tilt gear of the electronic pen 1000 is obtained.

This may be the case, as in the above example, where the electronic pen stores mapping data reflecting the correspondence between the tilt angles of all reference directions and the tilt gear positions of the electronic pen 1000.

This may also be the case, as in the above example, where the server stores a mapping function representing the tilt angles of all reference directions and the tilt gear of the electronic pen 1000, e.g. P_t＝F(P_X,P_Y,P_Z) The current tilt angle of the electronic pen 1000 is obtained in accordance with the mapping function and the current tilt angles of all the reference directions.

In step S2300, the electronic pen 1000 generates gear information including a current tilt gear.

In one example, the gear information may be generated each time the current tilt gear of the electronic pen 1000 is obtained, for transmission to the sensing device 2000.

In an example, after obtaining the current tilt gear of the electronic pen 1000, it may be detected whether the current tilt gear changes from the last tilt gear obtained, and when the current tilt gear changes from the last tilt gear, the gear information including the current tilt gear is generated, so as to reduce data processing amount of both communication parties and improve response speed.

In this example, for the case where only one reference direction is provided, the current tilt tap position of the reference direction is the current tilt tap position of the electronic pen 1000, and if the current tilt tap position changes from the previous tilt tap position, the current tilt tap position of the electronic pen 1000 changes from the previous tilt tap position of the electronic pen 1000.

In this example, for the case where the current tilt range of the electronic pen 1000 is constituted by the current tilt ranges of the plurality of reference directions, for example, the current tilt range P_t＝(P_X,P_Y,P_Z) Last inclined gear P_t-1＝(P_X,P_Y,P_Z) Here, as long as P_X,P_Y,P_ZAny value of the two values is changed, which results in the current inclined gear P_tRelative last inclined gear P_t-1A change occurs.

In this example, the current tilt range for the stylus 1000 is mapped by the mapping function P ═ F (P)_X,P_Y,P_Z) In the determined case, the current tilt gear is denoted as P_t＝F(P_X,P_Y,P_Z) The last tilting step is denoted as P_t-1＝F(P_X,P_Y,P_Z) If P is_tRelative P_t-1If the value of (2) is changed, the current tilt position of the electronic pen 1000 is changed relative to the previous tilt position of the electronic pen 1000.

In one example, generating the gear information including the current tilt gear may further include: gear information including the amount of change in the current tilt gear is generated.

For example, the current tilt gear is P_t＝(P_X,P_Y,P_Z) The last inclined gear is P_t-1＝(P_X,P_Y,P_Z) Comparing the current tilting step with the last tilting step if only P exists_ZIf a change occurs, the gear information generated may include only the current inclinationP that has changed in the oblique gear_ZAt this time, the sensing device 2000 will determine the P of the previous inclined gear according to the agreement between both parties_X,P_YP as the current tilt gear_X,P_Y。

According to this example, the data transmission amount and the data processing amount can be further reduced to further improve the response speed.

In one example, the current tilt position of the electronic pen 1000 includes only one numerical value, e.g., has only one reference direction; as another example, the current tilt gear of the stylus 1000 is denoted as P_t＝F(P_X,P_Y,P_Z) In this example, the shift position information may contain only the current tilt shift position without additionally containing information about the reference direction.

In one example, the current tilt gear of the electronic pen 1000 is composed of current tilt gears of a plurality of reference directions, for example, the current tilt gear is represented as P_t＝(P_X,P_Y,P_Z) The gear information may further include a reference direction corresponding to each current tilting gear.

In one example, the current tilt gear of the electronic pen 1000 is composed of current tilt gears of a plurality of reference directions, for example, the current tilt gear is represented as P _t＝(P_X,P_Y,P_Z) For this reason, the gear information may be obtained by setting a transmission sequence of each current inclined gear, so that the sensing device 2000 determines the reference direction corresponding to each obtained current inclined gear according to a convention between the two parties, and it is not necessary to include the reference direction corresponding to each current inclined gear in the gear information.

In step S2400, the electronic pen 1000 sends the gear information to the sensing device 2000 of the electronic pen 1000.

In an example, the step S2400 of transmitting the gear information to the sensing device 2000 of the electronic pen 1000 by the electronic pen 1000 may further include the steps of:

in step S2410, the electronic pen 1000 digitally encodes the gear information to obtain corresponding digitally encoded information.

The digital code is a code using binary numbers 0 and 1, and the digital code information may be composed of binary numbers 0 and 1.

In this example, any digital encoding method may be adopted as long as the shift information can be decoded and obtained according to the agreement of both the transmitter and the receiver. Such as, but not limited to, non-return-to-zero encoding, manchester encoding, or differential manchester encoding.

For example, the electronic pen 1000 may obtain a current tilt angle of the electronic pen 1000 with respect to a set reference direction according to a scanning cycle, and obtain a current tilt gear of the electronic pen 1000 according to the current tilt angle every one scanning cycle, generate gear information, and digitally encode the gear information.

For another example, the electronic pen 1000 may obtain a current tilt angle of the electronic pen 1000 with respect to a set reference direction according to a scanning cycle, and obtain a current tilt gear of the electronic pen 1000 according to the current tilt angle every scanning cycle, but only when it is detected that the current tilt gear changes from a previous tilt gear, the gear information is generated and digitally encoded.

In step S2420, the electronic pen 1000 controls the signal generating circuit of the electronic pen 1000 to switch between on and off according to the digital coding signal, so as to generate a varying sensing signal for the sensing device 2000 to receive.

The electronic pen 1000 may include a signal generating circuit 1010, and the processor 1012 of the electronic pen 1000 may control the signal generating circuit 1010 to generate a changing sensing signal according to the digital coding signal, where the sensing signal is configured to represent gear information, which may be understood as that the changing sensing signal carries the gear information, and after receiving the changing sensing signal, the sensing device 2000 may decode the changing sensing signal according to a communication protocol agreed by both the transceiver and the transmitter to obtain the gear information.

In this example, since the shift information includes the current tilt shift of the electronic pen 1000, the sensing device 2000 may execute the task corresponding to the current tilt shift after receiving the changed sensing signal.

In this example, the electronic pen 1000 may be configured with a switching circuit connected to the signal generating circuit 1010, and the switching circuit may gate-connect the first switch or the second switch under the action of the gate control signal. After the electronic pen 1000 digitally encodes the gear information and obtains a corresponding digital encoded signal, the electronic pen 1000 may use the digital encoded signal as a gating control signal to control the gating connection of the switching circuit, and further control the signal generating circuit 1010 to switch between on and off.

For example, the switching circuit is controlled to gate the first switch when the digital code signal is 0, and to gate the second switch when the digital code signal is 1.

For another example, when the first switch is gated on, the signal generation circuit 1010 is turned on, and the signal generation circuit 1010 generates a resonance signal of a fixed frequency, and when the second switch is gated on, the signal generation circuit 1010 is turned off, and at this time, the signal generation circuit 1010 generates a low level signal.

According to the steps S2410 to S2420, the signal generating circuit 1010 is controlled to generate the changed sensing signal based on the digital coding signal, so as to transmit the information. Because the digital signal has the characteristic of strong anti-interference performance compared with the analog signal, the anti-interference performance of the electronic pen 1000 can be obviously improved, which is beneficial to ensuring that the pen pressure of the electronic pen 1000 presents stable linear change and improving the writing experience.

According to the method of the present embodiment, the current tilt gear of the electronic pen 1000 is determined based on the current tilt angle of the electronic pen 1000, so as to generate gear information including the current tilt gear of the electronic pen 1000, and the gear information is sent to the sensing device 2000 of the electronic pen 1000, thereby implementing information transmission. Here, since the embodiment of the present invention determines the current tilt gear of the electronic pen 1000 according to the current tilt angle of the electronic pen 1000 and then transmits the current tilt gear to the sensing device 2000 of the electronic pen 1000, the sensing device 2000 of the electronic pen 1000 may perform operations and processes matched with the current tilt gear, thereby improving user experience.

For the method of this embodiment, the electronic pen 1000 determines the current tilt gear based on the current tilt angle and sends the current tilt gear to the sensing device 2000, which effectively reduces the data processing amount of the electronic pen 1000 and the sensing device 2000, reduces the data amount that the electronic pen 1000 needs to send to the sensing device 2000, further reduces the error rate, and improves the response speed of implementing corresponding functional operation through angle detection, thereby improving user experience.

Fig. 5 is a schematic flowchart of an angle information processing method according to another embodiment of the present invention, which is also implemented by the electronic pen 1000.

Referring to fig. 5, the angle information processing method of the present embodiment may further include:

in step S3100, the electronic pen 1000 detects whether the angle detection function is turned on.

For example, the electronic pen 1000 may provide an angle detection function and a non-angle detection function.

In step S3200, when the angle detection function is activated, the electronic pen 1000 further performs the step of obtaining the current tilt angle of the electronic pen 1000 with respect to the set reference direction.

Accordingly, when the angle detection function is not turned on, the electronic pen transmits only information for locating the pen tip position and pen tip pressure information to the sensing device 2000, and does not transmit the position information.

As can be seen from steps S3100 to S3200, in this example, when the on-angle detection function is detected, the step of acquiring the current tilt angle of the electronic pen 1000 with respect to the set reference direction is performed, so that a plurality of function modes are supported, and thus, the operator can flexibly select a desired function mode.

Fig. 6 is a schematic flowchart of an angle information processing method according to another embodiment of the present invention.

Referring to fig. 6, the angle information processing method of the present embodiment is implemented by the sensing device 2000, and may include the steps of:

in step S4100, the sensing device 2000 acquires the gear information sent by the electronic pen 1000.

The shift information includes a current tilt shift of the electronic pen 1000, and the current tilt shift indicates a current tilt angle at which the electronic pen 1000 is tilted with respect to a set reference direction.

In this embodiment, the sensing device 2000 may be configured with a signal receiving circuit to receive the changed sensing signal sent by the electronic pen 1000, and decode the received changed sensing signal to obtain and respond to the gear information sent by the electronic pen 1000.

In step S4200, the sensing device 2000 obtains a task item corresponding to the current tilt gear.

The task item may include at least one of a position correction item and a function setting matching item.

The above position correction items are used to compensate and correct the position of the electronic pen 1000 when the electronic pen 1000 is tilted. Here, since the position where the sensing signal of the sensing device 2000 is strongest is located near the coil at the front end of the electronic pen 1000, not the pen tip, the sensing device 2000 actually performs positioning according to the coil position rather than the actual pen tip position for detecting the position of the electronic pen 1000, and therefore, when the electronic pen 1000 is vertically and obliquely inclined by a certain angle, the sensing device 2000 obtains a detection value of the pen tip position according to the coil positioning, and a deviation occurs from an actual value of the pen tip position.

The sensing device 2000 may preset a corresponding relationship between the function setting and the current tilt gear of the electronic pen 1000, and the user may trigger the corresponding function implementation by operating the electronic pen 1000 according to the corresponding relationship.

For example, when the electronic pen 1000 is horizontal (the lowest vertical gear), a function of switching to a low power consumption mode is corresponding to the electronic pen 1000; for another example, when the electronic pen 1000 is inverted (vertical inverted gear), an eraser function is correspondingly performed; for another example, when the pen point of the electronic pen 1000 is downward (vertical position, for example, including the vertical first gear to the vertical third gear), the normal writing function is performed.

In an example, after acquiring the gear information sent by the electronic pen 1000, the sensing device 2000 may first detect whether to turn on the authority to execute the task item according to the gear information, for example, the authority is turned on, and then execute the step S4200.

In this example, the user may select to turn the right on or off via the sensing device 2000.

In step S4300, the sensing device 2000 executes the task item acquired in step S4200.

In one example, the task item may include the above location fix item.

In this example, the sensing device 2000 executing the task item according to the current tilt gear in step S4300 may further include:

In step S4311, the sensing device 2000 detects the current position coordinates of the pen tip of the electronic pen 1000 as the detected position coordinates.

In step S4312, the sensing device 2000 obtains a correction vector corresponding to the current tilt gear.

The correction vector includes a correction value and a correction direction.

The current tilt gear stage includes a current tilt gear stage corresponding to the vertical reference direction and a current tilt gear stage corresponding to the horizontal reference direction, and may be, for example, a current tilt gear stage corresponding to the horizontal reference direction X and the horizontal reference direction Y.

In this example, the step S4312 may further include the steps of:

and S4312-1, acquiring a correction value according to the current inclined gear division corresponding to the vertical reference direction.

And S4312-2, acquiring a correction direction according to the current inclined gear division corresponding to the horizontal reference direction.

In another example, the above correction direction may be a preset fixed direction, and the fixed correction direction information may be determined according to left-hand use or right-hand use information provided by the user, for example, when the user uses the electronic pen 1000 to write normally with the right hand, the inclination angle with respect to the horizontal reference direction Y is usually about 135 °. In this further example, it may be that the correction value of the current tilt position is obtained according to step S4312-1, and the preset fixed direction is taken as the correction direction of the current tilt position.

In step S4313, the sensing device 2000 obtains the actual position coordinates of the pen tip 1000 based on the detected position coordinates and the correction vector.

In step S4313, the actual position coordinates of the pen tip, that is, the correction length corresponding to the correction value, are obtained by moving the correction value in the correction direction by the correction amount from the detected position coordinates of the pen tip as the start point.

According to steps S4311 to S4313, the example sensing device 2000 corrects the current position coordinates of the electronic pen 1000 according to the correction vector corresponding to the current tilt gear to obtain the actual position coordinates of the pen tip, thereby improving the writing accuracy.

In one example, the task item may also include the above function setting matching item.

In this example, the sensing device 2000 performing the task item according to the current tilt gear in step S4300 may further include:

step S4321, detecting whether matched function setting exists according to the current inclined gear.

In step S4322, when there is a matching function setting, an operation corresponding to the matching function setting is performed.

For example, the current tilt gear of the electronic pen 1000 indicates that the current tilt angle from the vertical reference direction is 90 °, and the function setting matched therewith includes setting the sensing device 2000 to enter the low power consumption mode.

For another example, the current tilt range of the electronic pen 1000 is a vertically inverted range indicating that the current tilt angle of the electronic pen 1000 from the vertical reference direction is 90 ° < θ_ZLess than or equal to 180 degrees, or the vertical inverted gear represents the current inclination angle of the electronic pen 1000 to the vertical reference direction of 150 degrees less than or equal to theta_ZLess than or equal to 180 degrees, and the matched function setting comprises the function of starting the eraser.

For another example, the current tilt gear of the electronic pen 1000 is a positive vertical third gear, which represents the electronic pen 1000 andcurrent tilt angle 0 ° < θ in vertical reference direction_ZAnd (3) less than 30 degrees, and the matched function setting comprises the step of informing the painting application to start the painting function and the like.

According to steps S4321 to S4322, the example sensing device 2000 executes a corresponding matched function setting when there is a function setting matched with the current tilt gear, thereby improving the writing experience.

According to the method of the embodiment, it may acquire the gear information including the current tilt gear of the electronic pen 1000 and execute the task item matching the current tilt gear. Here, since the current tilt gear of the electronic pen 1000 is determined according to the current tilt angle of the electronic pen 1000 in the embodiment of the present invention, the sensing device 2000 may perform an operation and a process matched with the current tilt gear, thereby improving user experience.

In one embodiment, the angle information processing method of the present invention may further include:

in step S5100, the sensing device 2000 provides a setting entry in response to an operation of performing matching setting.

The setting entry may be an input box, a drop-down list, a voice input, etc., for example, a designer may input a gear and a corresponding function through the input box; for another example, a designer may select a gear and a corresponding function through a drop-down list; also for example, the designer may voice-input the gear and corresponding function.

In step S5200, the sensing device 2000 acquires the setting contents input through the setting entry.

For example, the input range is "vertical lowest range", and the input corresponding function is "the electronic pen 1000 is switched to the low power consumption mode".

For another example, the input gear is a "vertical upside down gear", and the input corresponding function is an "eraser function".

In step S5300, the electronic pen 1000 adds the setting contents in the database.

According to the steps S5100-S5300, the example provides a man-machine interaction interface to support a designer to match the function setting matched with the current inclined gear according to the current actual requirement, so that customized design is realized.
