Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0032] In the prior art, the functions of gesture recognition and pen-holding posture correction for the stylus are relatively simple.
[0033] Based on the above reasons, the embodiment of the present application provides a stylus pen for optimizing posture recognition, including a pen body, a pen holding detection component, an inclination detection component, a gyroscope and a control component. The pen holding detection component is arranged on the surface of the pen body and is used to detect the user's pen holding position characteristics, the inclination detection component is used to detect the inclination characteristics of the pen body, the gyroscope is used to detect the movement characteristics of the pen body, the control component is electrically connected to the pen holding detection component, the inclination detection component and the gyroscope respectively, and the control component is used to switch the type of the stylus tip according to the inclination characteristics and the movement characteristics of the pen body, and to issue a pen holding prompt information for correcting the user's pen holding posture according to the type of the pen tip and the user's pen holding position characteristics. The embodiment of the present application can perform posture recognition and pen holding posture correction for different types of styluses when the tip of the stylus is used as a stylus of different types, thereby improving the user experience of the stylus.
[0034] In some scenarios, a stylus pen with optimized gesture recognition according to an embodiment of the present application can be applied to input devices on electronic devices such as tablet computers. It has the function of simulating writing with a brush, a hard pen or a fountain pen, and can be optimized for different types of stylus tips, thereby improving the user experience of the stylus.
[0035] The following is a detailed description of a stylus pen for optimizing gesture recognition provided by an embodiment of the present application with reference to specific examples.
[0036] Figure 1 A schematic diagram of the structure of a stylus pen for optimizing gesture recognition provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the handwriting pen includes a pen body 1, a pen holding detection component 2, an inclination detection component 3, a gyroscope 4 and a control component 5. The pen holding detection component 2 is arranged on the surface of the pen body 1 and is used to detect the user's pen holding position characteristics, the inclination detection component 3 is used to detect the inclination characteristics of the pen body 1, and the gyroscope 4 is used to detect the movement characteristics of the pen body. The control component 5 is electrically connected to the pen holding detection component 2, the inclination detection component 3, and the gyroscope 4 respectively. The control component 5 is used to switch the pen tip type of the handwriting pen according to the inclination characteristics and the pen body movement characteristics, and send pen holding prompt information to correct the user's pen holding posture according to the pen tip type and the user's pen holding position characteristics.
[0037] like Figure 1 As shown, structurally, the stylus pen includes a pen body 1, a pen grip detection component 2, an inclination detection component 3, a gyroscope 4 and a control component 5. The pen body 1 is the main structure of the stylus pen, the pen grip detection component 2, the inclination detection component 3 and the gyroscope 4 are sensors of the stylus pen, and the control component 5 is used to control the working state of the stylus pen.
[0038] Exemplarily, other modules such as batteries and communication components may be integrated on the control component 5 .
[0039] like Figure 1As shown, the pen holding detection component 2 is arranged on the surface of the pen body 1 and is used to detect the user's pen holding position characteristics. The pen holding detection component 2 can be made of a matrix flexible PCB board that can detect the pen holding position of the finger. The surface array of the flexible PCB board is provided with a plurality of pressure detectors or capacitance sensors. The pressure detectors or capacitance sensors can detect the electrical signal generated on the pen holding detection component 2 when the finger contacts the pen holding detection component 2. The control component 5 can receive the electrical signal generated by the pen holding detection component 2 to detect the finger position, thereby enabling the control component 5 to further correct the pen holding posture of the detected finger position.
[0040] Exemplarily, when the control component 5 corrects the pen-holding posture, the control component 5 first determines the center point of the contact area between the finger detected by the pen-holding detection component 2 and the pen-holding detection component 2, and determines whether the user's pen-holding posture is correct based on the position distribution characteristics of the center point of the contact area.
[0041] Exemplarily, when determining the user's pen holding position, the control component 5 first determines the center point of the contact area between the finger detected by the pen holding detection component 2 and the pen holding detection component 2, and uses the midpoint of the line connecting the center points of the contact area between each finger and the pen holding detection component 2 as the midpoint of the pen holding position. When detecting the position of the user's pen holding position relative to the pen tip or the pen tail, the distance from the pen tip or the pen tail of the stylus can be calculated to obtain the midpoint of the pen holding position.
[0042] Exemplarily, the inclination detection component 3 is used to detect the inclination characteristics of the pen body 1, and then the state of the stylus can be controlled according to the inclination characteristics of the stylus.
[0043] When in use, the gyroscope 4 is used to detect the movement characteristics of the stylus body, and then the state of the stylus can be controlled according to the movement characteristics of the stylus body.
[0044] Structurally, Figure 2 A schematic diagram of a control structure of a stylus pen for optimizing gesture recognition provided in an embodiment of the present application is shown as follows: Figure 1 and Figure 2 As shown, the control component 5 is electrically connected to the pen holding detection component 2, the inclination detection component 3, and the gyroscope 4, respectively, so that the control component 5 can centrally control the working state of the stylus. The control component 5 is used to switch the pen tip type of the stylus according to the inclination characteristics and the pen body movement characteristics, and issue pen holding prompt information to correct the user's pen holding posture according to the pen tip type and the user's pen holding position characteristics. When the pen tip type is different, the user's correct pen holding posture is also different, and then the pen holding prompt information to correct the user's pen holding posture can be issued according to the pen tip type and the user's pen holding position characteristics, thereby improving the adaptability of correcting the pen holding posture of the stylus.
[0045] Exemplarily, when the stylus pen tip type is switched, the control component 5 sends an electrical signal for switching the stylus pen tip type to the tablet computer paired with the stylus pen, so that the tablet computer can switch and display the stylus pen tip type accordingly.
[0046] Exemplarily, when the tilt angle of the stylus is less than 10°, and when the motion characteristics of the stylus body match the motion characteristics of a writing brush during writing, the tip type of the stylus is switched to a writing brush.
[0047] Exemplarily, when the tilt angle of the stylus is greater than 30°, and when the motion characteristics of the stylus body conform to the motion characteristics of a hard pen when writing, the tip type of the stylus is switched to a hard pen.
[0048] During operation, when the pen tip type is a writing brush, and the user's pen holding position characteristics are greatly different from the preset pen holding position characteristics of the writing brush, a pen holding prompt message can be issued to correct the writing brush holding posture.
[0049] During operation, when the pen tip type is a hard pen and the user's pen holding position characteristics are greatly different from the preset hard pen holding position characteristics, pen holding prompt information for correcting the hard pen holding posture can be issued.
[0050] The beneficial effect brought by the above implementation method is that the pen tip type of the stylus can be switched according to the inclination angle characteristics and the pen body movement characteristics, and the pen tip type of the stylus is accurately detected and switched. At the same time, it can detect the user's pen holding position characteristics, and issue pen holding prompt information to correct the user's pen holding posture according to the pen tip type and the user's pen holding position characteristics. It is suitable for posture correction when the stylus is used as a stylus of different types, improves the scalability of monitoring the pen holding posture of the stylus, and improves the use effect of the stylus.
[0051] In some implementations, the gyroscope 4 includes a tip gyroscope 41 and a tail gyroscope 42 respectively disposed at the two ends of the pen body 1, the tip gyroscope 41 is used to collect the tip motion characteristics, the tail gyroscope 42 is used to collect the tail motion characteristics, and the control component 5 is used to switch the pen tip type according to the inclination characteristics, the tip motion characteristics and the tail motion characteristics.
[0052] When the stylus is used as a stylus of different types, the inclination angle of the pen body and the motion characteristics of the pen body are different. In order to further improve the detection accuracy of the motion characteristics of the pen body, a gyroscope can be set at both ends of the pen body 1, and then the type of the stylus tip can be controlled according to the motion characteristics of the pen body 1 detected by the gyroscopes at both ends of the pen body 1.
[0053] When the stylus is used as different types of stylus, the movement characteristics of the pen tip and the pen tail are different. For example, when the stylus is used as a writing brush, the stylus as a whole is basically in a state of translational motion in the horizontal plane, and the movement characteristics of the pen tip and the pen tail are relatively similar; when the stylus is used as a hard pen, the movement amplitude of the stylus tip is greater than the movement amplitude of the pen tail, and the movement characteristics of the stylus tip and the pen tail are quite different.
[0054] Figure 3 A schematic diagram of the structure of another stylus pen for optimizing gesture recognition provided in an embodiment of the present application is shown as follows: Figure 3 As shown, the gyroscope 4 includes a tip gyroscope 41 and a tail gyroscope 42 respectively arranged at the two ends of the pen body 1, the tip gyroscope 41 is used to collect the motion characteristics of the tip, and the tail gyroscope 42 is used to collect the motion characteristics of the tail. The control component 5 is used to switch the pen tip type according to the inclination characteristics, the tip motion characteristics and the tail motion characteristics.
[0055] Exemplarily, when the difference between the motion feature of the pen head and the motion feature of the pen tail is less than a preset motion feature difference, and when the tilt angle of the stylus is less than 10°, the tip type of the stylus is switched to a brush.
[0056] Exemplarily, when the difference between the motion feature of the pen head and the motion feature of the pen tail is greater than a preset motion feature difference, and when the tilt angle of the stylus is greater than 30°, the tip type of the stylus is switched to a hard pen.
[0057] Exemplarily, the preset motion characteristic difference may be a first acceleration difference of acceleration in the same direction or a first angular acceleration difference of angular acceleration.
[0058] The beneficial effect brought by the above implementation method is that the tip type of the stylus pen can be controlled according to the movement characteristics of the pen head, the movement characteristics of the pen tail and the tilt angle characteristics of the stylus pen, thereby improving the sensitivity of controlling the tip type of the stylus pen.
[0059] In some implementations, the embodiments of the present application also include a pen tip 11 and a circumferential pressure detection component 12 disposed at one end of the pen body 1. The circumferential pressure detection component 12 is disposed on the circumference of the pen tip 11 in the pen body 1. The circumferential pressure detection component 12 is used to detect the pressure exerted on the pen tip 11 at different circumferential angles. When the pen tip type is a hard pen, the control component 5 is used to issue pen holding prompt information for correcting the user's pen holding posture according to the pressure exerted on the pen tip 11 at different circumferential angles and the user's pen holding position characteristics.
[0060] Figure 4 for Figure 3 A schematic diagram of the local structure of a stylus at position A for optimizing gesture recognition, as shown in FIG. Figure 3 and Figure 4As shown, structurally, the stylus pen further includes a pen tip 11 and a circumferential pressure detection component 12 arranged at one end of the pen body 1. The circumferential pressure detection component 12 is arranged on the circumference of the pen tip 11 in the pen body 1. The circumferential pressure detection component 12 can be made by a plurality of piezoresistors arranged on the circumference of the pen tip 11. The circumferential pressure detection component 12 is used to detect the pressure applied to the pen tip 11 at different circumferential angles. The circumferential pressure detection component 12 is electrically connected to the control component 5, so that the working state of the stylus pen can be controlled according to the pressure applied to the pen tip 11 at different circumferential angles when in use.
[0061] When in use, when the pen tip type is a hard pen, due to the large inclination angle of the pen body 1, the circumferential pressure on the pen tip 11 is large. The control component 5 can obtain the user's pen-holding posture based on the pressure on the pen tip 11 at different circumferential angles and the user's pen-holding position characteristics, and then issue pen-holding prompt information to correct the user's pen-holding posture based on the user's pen-holding posture.
[0062] Exemplarily, when the pressure value applied to the pen tip 11 at a circumferential angle exceeds a preset circumferential pressure value, and when the distance from the user's pen-holding position to the tip of the pen tip 11 is less than a preset distance, it means that the user's pen-holding position is too close to the pen tip. At this time, a pen-holding prompt message is issued to correct the user's pen-holding posture, and the pen-holding prompt message instructs the user to adjust the pen-holding position away from the pen tip 11.
[0063] The beneficial effect brought about by the above implementation method is that it can correct the user's pen-holding posture according to the pressure exerted on the pen tip at different circumferential angles and the user's pen-holding position characteristics, thereby improving the use effect of the stylus when the pen tip type is a hard pen.
[0064] In some implementations, the embodiments of the present application also include an axial pressure detection component 13, which is disposed at the end of the nib 11 in the pen body 1. The axial pressure detection component 13 is used to detect the axial pressure applied to the nib 11. When the nib type is a hard pen, the control component 5 is used to issue pen-holding prompt information to correct the user's pen-holding posture based on the axial pressure applied to the nib 11 and the pressure applied to the nib 11 at different circumferential angles to the user's pen-holding position characteristics.
[0065] like Figure 3 and Figure 4 As shown, the embodiment of the present application also includes an axial pressure detection component 13, which is arranged at the end of the pen tip 11 in the pen body 1. The axial pressure detection component 13 is used to detect the axial pressure applied to the pen tip 11, and then the pen holding posture of the stylus pen can be corrected according to the axial pressure applied to the pen tip 11.
[0066] When in use, when the pen tip type is a hard pen, the control component 5 is used to issue pen-holding prompt information to the user's pen-holding position characteristics based on the pressure exerted on the pen tip 11 in the axial direction and the pressure exerted on the pen tip 11 at different circumferential angles. The pen-holding prompt information is used to correct the user's pen-holding posture, thereby improving the posture correction effect of the stylus.
[0067] Exemplarily, when the pen tip type is a hard pen, if the pressure applied to the pen tip 11 in the axial direction is greater than a preset axial pressure value, and the pressure applied to the pen tip 11 at an angle in the circumferential direction is greater than a preset circumferential pressure value, it means that the user's pen holding position is too close to the pen tip 11, resulting in excessive force on the pen tip 11. At this time, a pen holding prompt message can be issued to prompt the user to adjust the pen holding posture so that the user's pen holding posture is adjusted toward the tail of the pen, thereby improving the posture correction effect of the stylus pen.
[0068] The beneficial effect brought about by the above implementation method is that the user's pen-holding posture can be corrected according to the pressure exerted on the pen tip in the axial direction and the pressure exerted on the pen tip at different circumferential angles, thereby improving the posture correction effect of the stylus.
[0069] In some implementations, a counterweight 14 capable of moving along the axial direction of the pen body 1 is provided in the pen body 1, and a dial head 141 is provided on the counterweight 14. The user can slide the counterweight 14 along the axial direction of the pen body 1 by turning the dial head 141. A counterweight detection component 15 capable of detecting the counterweight position of the counterweight 14 is provided in the pen body 1. The counterweight detection component 15 is electrically connected to the control component 5, and the control component 5 is used to issue a counterweight adjustment prompt message for adjusting the counterweight position according to the pen tip type, the user's pen holding position characteristics and the counterweight position.
[0070] Figure 5 A schematic diagram of the structure of another stylus pen for optimizing gesture recognition provided in an embodiment of the present application, Figure 6 for Figure 5 A schematic diagram of the local structure of a stylus at position B for optimizing gesture recognition, as shown in FIG. Figure 5 and Figure 6 As shown, structurally, a counterweight 14 capable of moving along the axial direction of the pen body 1 is provided in the pen body 1 . The counterweight 14 is a metal block. When the counterweight 14 slides up and down along the pen body 1 , the center of gravity of the pen body 1 can be adjusted.
[0071] like Figure 6As shown, the counterweight 14 is provided with a dial head 141, and the user can slide the counterweight 14 along the axial direction of the pen body 1 by turning the dial head 141, thereby adjusting the center of gravity position of the pen body 1; a counterweight detection component 15 capable of detecting the counterweight position of the counterweight 14 is provided in the pen body 1, and the counterweight detection component 15 is electrically connected to the control component 5, so that the control component 5 can obtain the position information of the counterweight 14.
[0072] Exemplarily, the counterweight detection component 15 may be a linear Hall sensor, the counterweight 14 is magnetic, and the counterweight detection component 15 can detect the position of the counterweight 14 .
[0073] When working, the control component 5 is used to issue weight adjustment prompt information for adjusting the weight position according to the pen tip type, the user's pen holding position characteristics and the weight position, so as to further improve the user's pen holding experience and enhance the user's writing experience.
[0074] Exemplarily, when the pen tip type is a writing brush, the control component 5 can issue a weight adjustment prompt message when it identifies, based on the writing brush tip type and the user's pen holding position characteristics, that the user's pen holding position is too close to the pen tip and the detected weight position is too close to the pen tip, to prompt the user to adjust the weight position to the side away from the pen tip, so that the center of gravity of the stylus is appropriately away from the pen tip, thereby improving the user experience of using the stylus as a writing brush.
[0075] The beneficial effect brought about by the above implementation method is that the writing pen can send weight adjustment prompt information to the weight position according to the pen tip type, the user's pen holding position characteristics and the weight position, thereby further improving the user's writing experience.
[0076] In some implementations, when the pen tip type is a hard pen, the control component 5 is used to issue a weight adjustment prompt message for adjusting the weight position based on the pressure applied to the pen tip 11 in the axial direction, the pressure applied to the pen tip 11 at different circumferential angles, the user's pen holding position characteristics, and the weight position.
[0077] During use, when the stylus is used in the hard pen working mode, if the center of gravity of the stylus is too close to the pen tip, the stylus will feel poor when used, and the pressure on the pen tip 11 in the axial direction and the pressure on the pen tip 11 at different circumferential angles will be affected by the center of gravity of the pen body 1 when holding the pen. In order to improve the user's writing experience, a weight adjustment prompt message for adjusting the weight position can be issued according to the pressure on the pen tip 11 in the axial direction, the pressure on the pen tip 11 at different circumferential angles, the user's pen holding position characteristics and the weight position, so as to prompt the user to adjust the weight position.
[0078] Illustratively, when the pressure applied to the pen tip 11 in the axial direction is greater than a preset first axial pressure value, the pressure applied to the pen tip 11 at an angle in the circumferential direction is greater than a preset first circumferential pressure value, and the user's pen holding position is too close to the pen tip, and the detected weight position is too close to the pen tip, a prompt message may be issued to adjust the weight position away from the pen tip, so as to prompt the user to adjust the weight position and improve the user experience when using the stylus pen as a hard pen.
[0079] The beneficial effect brought about by the above-mentioned implementation method is that when the stylus is in hard pen working mode, the weight position can be adjusted and optimized according to the axial pressure on the pen tip, the pressure on the pen tip at different circumferential angles, the user's pen holding position characteristics and the weight position, thereby improving the user's stylus pen usage experience.
[0080] In some implementations, when the pen tip type is a writing brush, the control component 5 is used to issue a weight adjustment prompt message for adjusting the weight position according to the axial pressure on the pen tip 11, the user's pen holding position characteristics, and the weight position.
[0081] When in use, when the pen tip type is a writing brush, if the center of gravity position of the stylus pen does not match the pen holding position characteristics of the user, it will cause the user to have difficulty controlling the strokes of the stylus pen when used as a writing brush. The pressure on the pen tip 11 in the axial direction directly affects the stroke feeling of the stylus pen when used as a writing brush. Therefore, the control component 5 can issue a weight adjustment prompt information for adjusting the weight position according to the pressure on the pen tip 11 in the axial direction, the pen holding position characteristics of the user, and the weight position, thereby improving the writing experience of using the stylus pen as a writing brush.
[0082] Illustratively, when the axial pressure applied to the pen tip 11 is greater than a preset second axial pressure value, the user's pen holding position is too close to the pen tip, and the detected weight position is too close to the pen tip, a prompt message may be issued to adjust the weight position away from the pen tip, so as to prompt the user to adjust the weight position and improve the user experience when using the stylus pen as a brush.
[0083] The beneficial effect brought about by the above implementation method is that the weight position is optimized and adjusted according to the axial pressure on the pen tip, the user's pen holding position characteristics and the weight position prompt, thereby improving the user experience when the stylus is used as a brush.
[0084] Figure 7 A flowchart of a method for controlling a stylus pen for optimizing gesture recognition provided by an embodiment of the present application is shown in FIG. Figure 7As shown, a control method of a stylus pen for optimizing gesture recognition provided in an embodiment of the present application is used to control the stylus pen for optimizing gesture recognition. The method includes S110 to S120, and S110 to S120 are described in detail below.
[0085] S110 , detecting the user's pen holding position characteristics through the pen holding detection component 2 , detecting the inclination characteristics of the pen body 1 through the inclination detection component 3 , and detecting the pen body movement characteristics through the gyroscope 4 .
[0086] When in use, the pen holding position characteristics of the user are detected by the pen holding detection component 2, the inclination characteristics of the pen body 1 are detected by the inclination detection component 3, and the pen body movement characteristics are detected by the gyroscope 4, so that the control component 5 can control the working state of the stylus according to the pen holding position characteristics, inclination characteristics and pen body movement characteristics.
[0087] S120, the control component 5 switches the pen tip type of the stylus according to the inclination angle characteristics and the pen body movement characteristics, and the control component 5 issues pen holding prompt information for correcting the user's pen holding posture according to the pen tip type and the user's pen holding position characteristics.
[0088] During use, the control component 5 may pre-store inclination characteristics and pen body motion characteristics corresponding to different pen tip types. When the control component 5 switches the pen tip type of the stylus according to the inclination characteristics and pen body motion characteristics, if the inclination characteristics and pen body motion characteristics of the stylus are similar to the inclination characteristics and pen body motion characteristics of a writing brush pre-stored in the control component 5, the control component 5 switches the pen tip type of the stylus to a writing brush; if the inclination characteristics and pen body motion characteristics of the stylus are similar to the inclination characteristics and pen body motion characteristics of a hard pen pre-stored in the control component 5, the control component 5 switches the pen tip type of the stylus to a hard pen.
[0089] Exemplarily, when the tilt angle of the stylus is less than 10° and when the motion characteristics of the stylus body match the motion characteristics of a writing brush during writing, the tip type of the stylus is switched to a writing brush.
[0090] Exemplarily, when the tilt angle of the stylus is greater than 30° and when the motion characteristics of the stylus body conform to the motion characteristics of a hard pen when writing, the tip type of the stylus is switched to a hard pen.
[0091] When in use, the control component 5 can issue pen-holding prompt information to correct the user's pen-holding posture according to the pen tip type and the user's pen-holding position characteristics, and can correct the user's pen-holding posture according to the user's pen tip type.
[0092] During operation, when the pen tip type is a writing brush, and the user's pen holding position characteristics are greatly different from the preset pen holding position characteristics of the writing brush, a pen holding prompt message can be issued to correct the writing brush holding posture.
[0093] During operation, when the pen tip type is a hard pen and the user's pen holding position characteristics are greatly different from the preset hard pen holding position characteristics, pen holding prompt information for correcting the hard pen holding posture can be issued.
[0094] The beneficial effect brought about by the above-mentioned implementation method is that the pen tip type of the stylus can be switched in combination with the pen body movement characteristics and the tilt angle of the stylus, and the user's pen holding position can be reminded and corrected in combination with the pen tip type detected by the pen body and the user's pen holding position characteristics, thereby improving the accuracy of correcting the user's pen holding and improving the extensibility of the functions when using the stylus.
[0095] In some implementations, the above method further includes S210 to S220, and S210 to S220 are described in detail below.
[0096] S210 , collecting the motion characteristics of the pen tip through the pen tip gyroscope 41 , and collecting the motion characteristics of the pen tail through the pen tail gyroscope 42 .
[0097] Structurally, the gyroscope 4 includes a tip gyroscope 41 and a tail gyroscope 42 respectively arranged at the two ends of the pen body 1. The tip gyroscope 41 collects the motion characteristics of the pen tip, and the tail gyroscope 42 collects the motion characteristics of the pen tail. The tip gyroscope 41 and the tail gyroscope 42 can improve the accuracy of detecting the motion characteristics of the stylus.
[0098] S220, the control component 5 switches the pen tip type of the stylus according to the inclination angle feature, the pen head movement feature and the pen tail movement feature.
[0099] When in use, when the stylus cooperates with the device bound to the stylus to simulate the use of different types of pen tips, the control component 5 can switch the pen tip type of the stylus according to the inclination characteristics, the pen head movement characteristics and the pen tail movement characteristics, and can further improve the recognition accuracy of the pen tip type according to the pen head movement characteristics and the pen tail movement characteristics of the stylus.
[0100] Exemplarily, the pen tip motion characteristics and the pen tail motion characteristics may include velocity characteristics such as acceleration and angular acceleration.
[0101] Exemplarily, when the usage characteristic of a writing brush is that the relative movement amplitude of the pen tip and the pen tail is not large, when the difference between the motion characteristic of the pen tip and the motion characteristic of the pen tail is less than the preset motion characteristic difference, and when the tilt angle of the stylus pen is less than 10°, the handwriting characteristics of the stylus pen are more in line with the usage characteristics of the writing brush, and the tip type of the stylus pen can be switched to a writing brush.
[0102] Exemplarily, the usage characteristic of a hard pen is that the relative movement amplitude of the pen tip and the pen tail is large. When the difference between the motion characteristics of the pen tip and the motion characteristics of the pen tail is greater than the preset motion characteristic difference, and when the tilt angle of the stylus is greater than 30°, the handwriting characteristics of the stylus are more in line with the usage characteristics of a hard pen, and the tip type of the stylus can be switched to a hard pen.
[0103] Exemplarily, the preset motion feature difference may be a preset difference in absolute values of angular acceleration in the same direction.
[0104] The beneficial effect brought about by the above implementation method is that the motion characteristics of the stylus can be accurately detected in combination with the motion characteristics of the pen tip and the pen tail, and the type of the stylus can be detected according to the motion characteristics of the pen tip and the pen tail, thereby improving the accuracy of detecting the working mode of the stylus.
[0105] In some implementations, the above method further includes S310 to S320, and S310 to S320 are described in detail below.
[0106] S310 , detecting the pressure exerted on the pen tip 11 at different circumferential angles through the circumferential pressure detection component 12 .
[0107] like Figure 3 and Figure 4 As shown, structurally, the circumferential pressure detection component 12 is arranged on the circumference of the pen tip 11 in the pen body 1. The circumferential pressure detection component 12 detects the pressure applied to the pen tip 11 at different circumferential angles, and can control the working state of the stylus pen in combination with the force state of the pen tip 11.
[0108] S320: When the pen tip type is a hard pen, the control component 5 issues pen-holding prompt information for correcting the user's pen-holding posture according to the pressure exerted on the pen tip 11 at different circumferential angles and the user's pen-holding position characteristics.
[0109] For example, when the pressure value applied to the pen tip 11 at one circumferential angle exceeds a preset circumferential pressure value, it indicates that the user's pen-holding posture is not standard, which results in excessive lateral force on the pen tip 11 when the user uses the stylus.
[0110] Exemplarily, when the pressure value applied to the pen tip 11 at a circumferential angle exceeds a preset circumferential pressure value, and when it is detected that the distance from the user's pen-holding position to the tip of the pen tip 11 is less than a preset distance, it means that the user's pen-holding position is too close to the pen tip. At this time, a pen-holding prompt message is issued to correct the user's pen-holding posture. The pen-holding prompt message instructs the user to adjust the pen-holding position away from the pen tip 11 to correct the user's pen-holding posture.
[0111] Exemplarily, when detecting the distance from the user's pen holding position to the tip of the pen tip 11 , the detection may be performed by detecting the distance from the center points of the user's multiple pen holding fingers to the tip of the pen tip.
[0112] The beneficial effect brought about by the above-mentioned implementation method is that it can detect the user's pen-holding posture by combining the pressure exerted on the pen tip at different circumferential angles, the user's pen-holding position and the distance between the user's pen-holding position and the pen tip, and can correct the user's pen-holding posture more accurately.
[0113] In some implementations, the above method further includes S410 to S420, and S410 to S420 are described in detail below.
[0114] S410 , detecting the axial pressure applied to the pen tip 11 through the axial pressure detection component 13 .
[0115] When in use, the axial pressure applied to the pen tip 11 can be further detected by the axial pressure detection component 13 , and the working state of the stylus pen can be controlled according to the axial pressure applied to the pen tip 11 detected by the axial pressure detection component 13 .
[0116] S420. When the pen tip type is a hard pen, the control component 5 issues pen-holding prompt information for correcting the user's pen-holding posture according to the pressure exerted on the pen tip 11 in the axial direction and the pressure exerted on the pen tip 11 at different circumferential angles based on the user's pen-holding position characteristics.
[0117] Exemplarily, when the pen tip type is a hard pen, if the pressure applied to the pen tip 11 in the axial direction is greater than a preset axial pressure value, and the pressure applied to the pen tip 11 at an angle in the circumferential direction is greater than a preset circumferential pressure value, it means that the user's pen holding position is too close to the pen tip 11, and the user's pen holding posture causes the pen tip 11 of the stylus to be subjected to excessive forces in both the axial and circumferential directions. At this time, a pen holding prompt message may be issued to prompt the user to adjust the pen holding posture. The user's pen holding posture is adjusted toward the end of the pen, thereby improving the posture correction effect of the stylus.
[0118] The beneficial effect brought about by the above-mentioned implementation method is that the pen-holding posture of the stylus is detected by combining the axial pressure exerted on the pen tip, the pressure exerted on the pen tip at different circumferential angles, and the user's pen-holding position characteristics, thereby improving the effect of detecting and controlling the pen-holding posture of the stylus.
[0119] In some implementations, the above method further includes S510 to S520, and S510 to S520 are described in detail below.
[0120] S510 , detecting the counterweight position of the counterweight 14 through the counterweight detection component 15 .
[0121] When in use, the counterweight position of the counterweight 14 is detected by the counterweight detection assembly 15, so that the real-time position of the counterweight 14 can be obtained.
[0122] S520, the control component 5 issues a weight adjustment prompt message for adjusting the weight position according to the pen tip type, the user's pen holding position characteristics and the weight position.
[0123] Exemplarily, when the stylus pen is used with a brush tip, the control component 5 can issue a weight adjustment prompt message when it identifies, based on the brush tip type and the user's pen-holding position characteristics, that the user's pen-holding position is too close to the pen tip and the weight position is too close to the pen tip, to prompt the user to adjust the weight position to the side away from the pen tip, so that the user's pen-holding position can be appropriately away from the pen tip and the center of gravity of the stylus can be appropriately away from the pen tip, thereby improving the user experience of using the stylus pen as a brush.
[0124] The beneficial effect brought about by the above implementation method is that the weight position is prompted and adjusted according to the pen tip type, the user's pen holding position characteristics and the weight position, thereby improving the user experience of the stylus.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
