Description

Technical Field

[0001] The present application relates to the technical field of stationery, and in particular to a stylus pen in the technical field of stationery. Background Art

[0002] In recent years, the incidence of myopia in my country has shown a clear upward trend, and myopia has become a major public health issue affecting the eye health of Chinese people, especially young people. Myopia is usually related to sitting habits, such as incorrect reading and writing postures, incorrect pen holding postures, and incorrect pen holding positions.

[0003] A pen is a writing tool that people often use in their daily work and study. Many people ignore the correct pen holding position when using it, which leads to incorrect pen holding habits, thus laying the hidden danger of myopia. Therefore, there is an urgent need for a stylus that allows people to develop a good pen holding position and reduce the chance of myopia caused by incorrect pen holding habits. Summary of the invention

[0004] The present application provides a stylus pen for writing posture correction, which can correct the writing posture of a user.

[0005] In a first aspect, a stylus is provided, the stylus comprising a controller, a pen body, a plurality of first sensors and an alarm device, wherein a plurality of first small holes are arranged at a first position of a pen shaft in the pen body, the distance between the first position and a pen tip in the pen body is a first preset distance, the plurality of first sensors are located in the plurality of first small holes and detection signals received and sent by the first sensors can pass through the first small holes; the controller is used to: control the plurality of first sensors to transmit detection signals; detect whether the at least one first small hole is blocked when a user holds the stylus based on the detection signals transmitted by the plurality of first sensors and the detection signals returned from at least one of the plurality of first small holes; and control the alarm device to output a first warning signal when the user blocks the at least one first small hole when holding the stylus, the first warning signal being used to prompt the user that the position at which the stylus is held is close to the pen tip.

[0006] In the above technical solution, a plurality of first small holes are arranged at the first position of the pen shaft in the stylus, and a plurality of first sensors are arranged in the plurality of first small holes, and the detection signal received and sent by the first sensor in the first small hole can pass through the first small hole. When the user's holding position when writing with the stylus is located on the first small hole, the first sensor can detect that the first small hole is blocked. Since the first position where the first small hole is arranged is close to the pen tip, when the first sensor detects that the first small hole is blocked, the controller determines that the user's holding position is close to the pen tip, and then the controller issues an early warning through the alarm device, so that the user adjusts the holding position. The structure and method design of the writing pen of the present application can be used for correction of the holding position. When the stylus is used for a long time, the user can maintain a relatively correct holding position and will not approach the pen tip, thereby reducing the chance of suffering from myopia due to incorrect pen holding habits.

[0015] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0016] In the description of the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present application, "plurality" means at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0017] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0018] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0019] In the description of the present application, it should be understood that the terms "inside", "outside", "top", "bottom", "front", "back", etc., indicating directions or positional relationships (if any), are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present application.

[0020] Figure 1 It is a schematic diagram of the structure of a stylus provided in an embodiment of the present application.

[0021] For example, Figure 1 As shown, the stylus pen includes a pen body and a label on the pen body. In some embodiments, the pen body includes a pen cap, a pen head, a pen barrel and a pen core. In other embodiments, the pen body also includes a pen core telescopic structure. It should be understood that the label on the pen body is used to mark the name of the stylus pen, the color of the pen core, the diameter of the pen head, the purpose and other information. Usually, when a user uses a stylus pen to write, the user's correct holding position is as follows: Figure 1 The position interval indicated by l1 is shown.

[0022] However, some users hold the stylus very close to the pen tip when using it. Usually, in order to see the pen tip clearly, these users will tilt their heads to the left of the writing pen and their eyes will be very close to the book. If these users maintain this holding position for a long time, they may increase the chance of myopia.

[0023] In order to solve the above problems, the present application provides the following embodiments: Figure 2 A schematic diagram of the structure of another stylus is shown.

[0024] exist Figure 1 Based on the stylus shown, the stylus provided in the present application also includes a controller, a plurality of first sensors and an alarm device, wherein a plurality of first small holes are set at a first position of the pen shaft of the stylus, the distance between the first position and the pen tip in the pen body of the stylus is a first preset distance, the plurality of first sensors are located in the plurality of first small holes and the detection signals received and sent by the first sensors can pass through the first small holes.

[0025] In some embodiments, a plurality of first sensors can be disposed in the plurality of first small holes through a support frame, or the plurality of first sensors can be disposed on the surface of the pen core.

[0026] It should be understood that the multiple first small holes and the multiple first sensors in the present application are used to determine whether the user is close to the pen tip when holding the stylus. Therefore, the "first preset distance" in the present application can be specifically understood as: the distance close to the pen tip.

[0027] It should also be understood that the shape of the first small hole is not limited in the present application. In some embodiments, the shape of the plurality of first small holes includes at least one of a circle, a rhombus, a rectangle, a triangle and a parallelogram. It should also be understood that the number of the first small holes is not limited in the present application, and the number N of the first small holes is a positive integer. In the present application, the number of the first small holes is negatively correlated with the cross-sectional size of the first small holes. In some embodiments, when the number of the first small holes is small, a first small hole with a larger cross-section may be provided. This can avoid the situation where the user is very close to the pen tip when the number of the first small holes is small and the cross-section is small, but the first sensor cannot detect that at least one first small hole is blocked. In other embodiments, when the number of the first small holes is large, a first small hole with a smaller cross-section may be provided. In this way, the first sensor can more accurately detect the change in the grip of the user's hand near the plurality of first small holes, and accurately detect whether the user is close to the pen tip when holding the stylus.

[0028] For example, Figure 2 As shown in (a) of FIG. 1 , the controller, the alarm device and the first position of the plurality of first small holes are set. Figure 2 The right half of (a) in FIG. 1 also shows a schematic enlarged view of a plurality of first small holes, from which it can be seen that the shape of the first small holes is an ellipse. Figure 2 (b) in FIG. 1 shows a schematic cross-sectional view of the pen body at a first position. Figure 2 In (b), the detection signal emitted by sensor A among the plurality of first sensors can pass through the first small hole a, and the detection signal returned by sensor B among the plurality of first sensors can be received through the first small hole b. It should be understood that, see Figure 2 As shown in (b), when the user holds the stylus, the user's finger is located at the position indicated by O. At this time, after the detection signal emitted by sensor A reaches the first small hole a, due to the obstruction of the user's finger, a part of the detection signal will be reflected by the finger, and the reflected detection signal will return to sensor B through the first small hole b.

[0029] In order to more clearly illustrate the technical solutions provided in the embodiments of the present application, the present application provides the following Figure 3 The specific steps shown are used to introduce the functions of the controller in this application.

[0030] Step 301: The controller is used to control a plurality of first sensors to emit detection signals.

[0031] Step 302: The controller is used to detect whether the user blocks the at least one first small hole when holding the stylus based on the detection signals emitted by the multiple first sensors and the detection signal received from at least one first small hole among the multiple first small holes.

[0032] In some embodiments, the first sensor is a distance sensor, which includes any one of an ultrasonic sensor, a radar sensor, an infrared sensor and a laser sensor, and the corresponding detection signal is an ultrasonic signal, an electromagnetic wave signal, an infrared signal and a laser signal.

[0033] In the above technical solution, the distance sensor can emit a detection signal. When the detection signal encounters an obstacle, a part of the detection signal will be reflected by the obstacle, and the reflected detection signal will return to the distance sensor. In this regard, in the present application, it is possible to determine whether the first small hole is blocked by the detection signal emitted by the distance sensor and the detection signal received from at least one first small hole. Specifically, if the distance sensor does not receive the detection signal received from at least one first small hole, it indicates that the multiple first small holes are not blocked; if the distance sensor receives the detection signal received from at least one first small hole within a preset time, it indicates that the user blocks at least one first small hole when holding the stylus.

[0034] In a possible implementation, the controller is specifically used to: control a first distance sensor to transmit a detection signal, the first distance sensor being a distance sensor that transmits a detection signal among multiple distance sensors; receiving a returned detection signal through a second distance sensor, the second distance sensor being a distance sensor that receives a detection signal among the multiple distance sensors, and the second distance sensor corresponds to the first distance sensor; determining whether a time difference between the first distance sensor transmitting the detection signal and the second distance sensor receiving the detection signal is a preset duration; if the time difference is the preset duration, determining that the user blocks the at least one first small hole when holding the stylus; if the time difference is not the preset duration, determining that the user does not block the at least one first small hole when holding the stylus.

[0035] It should be understood that “the second distance sensor corresponds to the first distance sensor” in the above solution can be specifically understood as: the detection signal received by the second distance sensor is emitted by the first distance sensor.

[0036] In some embodiments, the controller is also used to: obtain a first distance between a first distance sensor and a first target aperture, the first target aperture being a first aperture among a plurality of first apertures corresponding to the first distance sensor; obtain a second distance between a second distance sensor and a first reference aperture, the first reference aperture being a first aperture among a plurality of first apertures corresponding to the second distance sensor; determine the sum of the first distance and the second distance as a total distance; and determine a ratio between the total distance and a propagation speed of a detection signal as the preset duration.

[0037] It should be understood that the first positions where the plurality of first apertures are arranged and the positions where the plurality of first sensors are arranged are artificially preset. Therefore, the distance between the center position of the first sensor and the center position of the first aperture, and the direction of the center position of the first sensor relative to the center position of the first aperture are determined. Therefore, the controller can obtain the distance between the first distance sensor and the first target aperture, and the distance between the second distance sensor and the first reference aperture.

[0038] It should also be understood that the first target aperture and the first reference aperture in the above solution are both first apertures among the plurality of first apertures. For ease of description, the first aperture corresponding to the first distance sensor is referred to as the first target aperture, and the first aperture corresponding to the second distance sensor is referred to as the first reference aperture.

[0039] It should also be understood that in the above scheme, “the first target hole corresponds to the first distance sensor” means that the detection signal emitted by the first distance sensor passes through the first target hole; and “the first reference hole corresponds to the second distance sensor” means that the detection signal passing through the first reference hole is received by the second distance sensor.

[0040] Step 303, when the user covers the at least one first small hole when holding the stylus, the controller is used to control the alarm device to output a first warning signal, and the first warning signal is used to prompt the user that the position when holding the stylus is close to the pen tip.

[0041] In some embodiments, the alarm device is a vibration motor, and the controller is specifically used to control the vibration motor to rotate at a preset vibration frequency when the user covers the at least one first small hole when holding the stylus.

[0042] In other embodiments, the alarm device is a Bluetooth device, and the controller is specifically used to send the warning signal to the user's mobile terminal through the Bluetooth device when the user covers the at least one first small hole when holding the stylus.

[0043] In the above technical solution, when the user covers the at least one first small hole when holding the stylus, it indicates that the user's holding position is close to the pen tip. When the user's holding position is close to the pen tip, the user is prompted by two methods: a vibration prompt of the vibration motor and a warning signal sent to the mobile terminal, so that the user adjusts the holding position of the stylus.

[0044] In a possible implementation, the stylus pen also includes a voice output device and multiple temperature sensors, the multiple temperature sensors are arranged on the surface of the pen shaft, and the distance between the multiple temperature sensors and the pen tip is in a first distance range; when the user blocks the at least one first small hole when holding the stylus pen, after controlling the alarm device to output a first warning signal, the controller is also used to: detect a first holding position of the user holding the stylus pen through the multiple temperature sensors, the first holding position being the position where the user's hand is closest to the pen tip; determine the distance difference between the first position and the first holding position as a first adjustment distance value; control the voice output device to output a first voice signal, and the first voice signal is used to prompt the user to move the first adjustment distance value in a direction away from the pen tip.

[0045] It should be understood that the lower limit of the distance of the first distance range is less than Figure 1 The p shown.

[0046] In the above technical solution, when the user blocks the at least one first small hole when holding the stylus, it indicates that the user's holding position is close to the pen tip. At this time, the controller can obtain the specific position (first holding position) of the user holding the pen through the multiple temperature sensors, and thus determine the first adjustment distance value for the user holding the pen based on the first holding position and the first position. The controller controls the voice output device to output a first voice signal, so that the user can move the first adjustment distance value in the direction away from the pen tip based on the current holding position based on the first adjustment distance value in the first voice signal. In the above manner, the present application can give the user a first voice signal specifically used to adjust the current holding position when the user's holding position is close to the pen tip. Thereby, the user can return to the correct holding position in the case of an incorrect holding position. After using the stylus of the present application for a long time, the user can maintain a good holding position and reduce the chance of suffering from myopia due to incorrect pen holding habits.

[0047] In one possible implementation, the controller is further specifically used to: detect the temperature of the surface area of ​​the pen shaft through the multiple temperature sensors; when it is detected that the temperature of the first area in the surface area is within the temperature range of a human hand, determine the position in the first area closest to the pen tip as the first holding position.

[0048] It should be understood that the "human hand temperature range" in the above solution can be specifically understood as: the temperature range of the fingers in the hand.

[0049] It should also be understood that the temperature of a human hand is related to the temperature of the surrounding environment that the user is in. Therefore, the method for determining the temperature range of a human hand in the above solution may adopt the following embodiments.

[0050] The first

[0051] In some embodiments, the controller is also used to: obtain the ambient temperature of the user; determine the sum of the ambient temperature and the first temperature as the first hand temperature; determine the sum of the ambient temperature and the second temperature as the second hand temperature; determine the temperature range formed by the first hand temperature and the second hand temperature as the hand temperature range; wherein the first temperature and the second temperature are both the temperature difference between the ambient temperature and the hand temperature, and the second temperature is greater than the first temperature.

[0052] In the above technical solution, the temperature difference between the ambient temperature and the temperature of the human hand is artificially preset and is obtained based on long-term practical life experience.

[0053] In some embodiments, the stylus also includes a fourth sensor disposed on the pen body, and the fourth sensor is used to sense the ambient temperature of the user. The controller is specifically used to: obtain a temperature signal through an external signal collector configured in the fourth sensor; convert the temperature signal into an electrical signal through the fourth sensor; and process the electrical signal to determine the ambient temperature.

[0054] Exemplarily, when the temperature of the first human hand is T1 and the temperature of the second human hand is T2, the temperature range of the human hand is [T1, T2].

[0055] Another example, when the ambient temperature is 24.5°C, the first temperature is 6°C, and the second temperature is 9°C, the first hand temperature is 30.5(24.5+6)°C, the second hand temperature is 33.5(24.5+9)°C, and the hand temperature range is [30.5°C, 33.5°C].

[0056] The second

[0057] In some embodiments, the controller is also specifically used to: determine the target gender of the user; determine the third temperature and the fourth temperature based on the target gender, the first temperature and the second temperature; determine the sum of the ambient temperature and the third temperature as the first hand temperature; determine the sum of the ambient temperature and the fourth temperature as the second hand temperature; wherein the third temperature and the fourth temperature are both the temperature difference between the ambient temperature and the hand temperature of the user of the target gender, and the fourth temperature is greater than the third temperature.

[0058] It should be understood that in the same environment, the hand temperatures of users of different genders are different. Generally, in the same environment, the hand temperature of women is lower than that of men, because women and men have different physiological functions.

[0059] Optionally, the stylus also includes an image acquisition device arranged on the pen body, and the controller is specifically used to: obtain a facial image of the user through the image acquisition device; input the facial image into a gender detection model, and the gender detection model recognizes the facial image based on gender characteristics to determine the target gender of the user.

[0060] Optionally, the gender detection model identifies the facial image based on gender features to determine the target gender of the user, including: the gender detection model identifies the facial image based on gender features; the gender detection model extracts facial features in the facial image, the facial features including the shape, size and position of the eyes, mouth, eyebrows and nose; the gender detection model matches the facial features with the gender features; when the facial features match the male features in the gender features, the gender detection model determines that the target gender is male; when the facial features match the female features in the gender features, the gender detection model determines that the target gender is female.

[0061] In some embodiments, the gender detection model matches the facial feature with the gender feature, including: the gender detection model matches the feature map corresponding to the facial feature with the feature map corresponding to the gender feature. If the similarity between the feature map corresponding to the facial feature and the feature map corresponding to the gender feature is greater than a preset similarity, the gender detection model determines that the facial feature matches the gender feature.

[0062] Optionally, the image acquisition device is a visual sensor, and the visual sensor is a camera.

[0063] Optionally, the controller is also specifically used for: when the target gender is female, determining the sum of the first temperature and the first adjustment temperature as the third temperature, and determining the sum of the second temperature and the first adjustment temperature as the fourth temperature, and the first adjustment temperature is related to the physiological skills of females; when the target gender is male, determining the sum of the first temperature and the second adjustment temperature as the third temperature, and determining the sum of the second temperature and the second adjustment temperature as the fourth temperature, and the second adjustment temperature is related to the physiological skills of males.

[0064] It should be understood that in the above two embodiments, the temperature range of the human hand is determined based on the difference between the ambient temperature of the user and the target temperature. In the first embodiment, the influence of the target gender on the temperature range of the human hand is not considered. In this way, the target temperature difference is the first temperature and the second temperature. In the second embodiment, the influence of the target gender on the temperature range of the human hand is considered. In this way, the target temperature difference is the third temperature and the fourth temperature, and the third temperature and the fourth temperature are obtained based on the first temperature, the second temperature and the adjusted temperature, and the adjusted temperature is related to the physiological skills of the target gender of the user.

[0065] In the above technical solution, two solutions for determining the temperature range of a human hand are provided. The first embodiment takes into account the influence of the ambient temperature of the user on the temperature range of the human hand, so that the determined temperature range of the human hand is more accurate. The second embodiment also takes into account the influence of the target gender (specifically, physiological function) on the temperature range of the human hand, so that the determined temperature range of the human hand is more accurate.

[0066] Exemplarily, the process of determining the temperature range of a human hand is described by taking the ambient temperature of 24.5°C, the first temperature of 6°C, the second temperature of 9°C, the first adjustment temperature of -1°C, and the second adjustment temperature of +1°C as an example.

[0067] When the target gender is female, the third temperature is 5 (6-1) ° C, the fourth temperature is 8 (9-1) ° C, the first hand temperature is 29.5 (24.5 + 5) ° C, the second hand temperature is 32.5 (24.5 + 8) ° C, and the hand temperature range is [29.5 ° C, 32.5 ° C].

[0068] When the target gender is female, the third temperature is 7 (6 + 1) ° C, the fourth temperature is 10 (9 + 1) ° C, the first hand temperature is 31.5 (24.5 + 7) ° C, the second hand temperature is 34.5 (24.5 + 10) ° C, and the hand temperature range is [31.5 ° C, 34.5 ° C].

[0069] It should be understood that some users hold the stylus far away from the pen tip when using it. If these users keep such a pen-holding habit for a long time, hand fatigue is likely to occur.

[0070] In order to solve the above problems, the present application provides the following embodiments: Figure 4 A schematic diagram of the structure of another stylus is shown.

[0071] exist Figure 2 Based on the stylus shown, the stylus provided in the present application also includes a plurality of second sensors, a plurality of second small holes are arranged at a second position of the pen shaft in the pen body, the distance between the second position and the pen tip is a second preset distance, the second preset distance is greater than the first preset distance, the plurality of second sensors are located in the plurality of second small holes and the detection signals received and sent by the second sensors can pass through the second small holes.

[0072] It should be understood that, like the plurality of first sensors, the plurality of second sensors can also be arranged in the plurality of second small holes through the support frame, or the plurality of second sensors can be arranged on the surface of the pen core. The relative position relationship between the second sensor and the second small hole can be referred to Figure 2 (b) in .

[0073] It should also be understood that the multiple second holes and multiple second sensors in the present application are used to determine whether the user is away from the pen tip when holding the stylus. Therefore, the "second preset distance" in the present application can be specifically understood as: the distance away from the pen tip.

[0074] It should also be understood that the shape of the second small hole is not limited in the present application. In some embodiments, the shape of the second small hole includes at least one of a circle, a rhombus, a rectangle, a triangle, and a parallelogram. The shape of the second small hole may be the same as or different from the shape of the first small hole. It should also be understood that the number of second small holes is not limited in the present application, and the number M of the second small holes is a positive integer. The number of second small holes may be the same as or different from the number of first small holes. In some embodiments, when the number of second small holes is small, a second small hole with a larger cross-section may be provided, so that the second sensor can more accurately detect whether the user is away from the pen tip when holding the stylus.

[0075] In order to more clearly illustrate the technical solutions provided in the embodiments of the present application, the present application provides the following Figure 5 The specific steps shown introduce the technical solution in this application.

[0076] Step 501, when the user holds the stylus pen without covering the plurality of first small holes, the controller is used to control the plurality of second sensors to emit detection signals;

[0077] Step 502, the controller is used to detect whether the user blocks the at least one second small hole when holding the stylus based on the detection signals emitted by the plurality of second sensors and the detection signal received from at least one second small hole among the plurality of second small holes;

[0078] Step 503, when the user covers the at least one second small hole when holding the stylus, the controller is used to control the alarm device to output a second warning signal, and the second warning signal is used to prompt the user to hold the stylus away from the pen tip.

[0079] It should be understood that the second sensor in the above scheme is the same as the first sensor. The second sensor is a distance sensor, which includes any one of an ultrasonic sensor, a radar sensor, an infrared sensor and a laser sensor, and the corresponding detection signal is an ultrasonic signal, an electromagnetic wave signal, an infrared signal and a laser signal.

[0080] In the above technical solution, a plurality of second small holes are further provided at the second position of the pen shaft in the stylus, and a plurality of second sensors are provided in the plurality of second small holes, and the detection signal received and sent by the distance sensor in the second small hole can pass through the second small hole. When the user holds the stylus without blocking the plurality of first small holes, it is determined whether the user blocks at least one second small hole when holding the stylus. Since the first position of the first small hole is close to the pen tip, and the second position of the second small hole is far from the pen tip, the above solution is relative to, when the user holds the stylus without being close to the pen tip, it is determined whether the user holds the stylus far from the pen tip. When the user holds the stylus far from the pen tip, the controller issues an early warning through the alarm device, so that the user adjusts the holding position. The structure and method design of the writing pen of the present application can be used for correction of the holding position. When the stylus is used for a long time, the user can maintain a relatively correct holding position and will not be far from the pen tip, thereby reducing the chance of suffering from myopia due to incorrect pen holding habits.

[0081] It should be understood that the implementation principle of "the controller is used to detect whether the user blocks the at least one second small hole when holding the stylus based on the detection signals emitted by the multiple second sensors and the detection signals received from at least one second small hole among the multiple second small holes" in the above scheme is the same as that of "the controller is used to detect whether the user blocks the at least one first small hole when holding the stylus based on the detection signals emitted by the multiple first sensors and the detection signals received from at least one first small hole among the multiple first small holes", which will not be repeated here.

[0082] In some embodiments, when the user covers the at least one second small hole when holding the stylus, after controlling the alarm device to output a second warning signal, the controller is also used to: detect a second holding position of the user holding the stylus through the multiple temperature sensors, the second holding position being the position where the user's hand is farthest from the pen tip; determine the distance difference between the second position and the second holding position as a second adjustment distance value; control the voice output device to output a second voice signal, the second voice signal being used to prompt the user to move the second adjustment distance value in a direction closer to the pen tip.

[0083] It should be understood that the implementation principle of "detecting the second holding position of the user holding the stylus through the multiple temperature sensors" and "detecting the first holding position of the user holding the stylus through the multiple temperature sensors" in the above solution is the same, and will not be repeated here.

[0084] In the above technical solution, when the user blocks at least one second small hole when holding the stylus, it indicates that the user's holding position is far away from the pen tip. At this time, the controller can obtain the specific position (second holding position) of the user holding the pen through the multiple temperature sensors, and thus determine the second adjustment distance value for the user holding the pen based on the second holding position and the second position. The controller controls the voice output device to output a second voice signal, so that the user can move the second adjustment distance value in the direction close to the pen tip based on the current holding position based on the second adjustment distance value in the second voice signal. In the above manner, the present application can give the user a second voice signal specifically used to adjust the current holding position when the user's holding position is far away from the pen tip. Thereby, the user can return to the correct holding position in the case of an incorrect holding position. After using the stylus of the present application for a long time, the user can maintain a good holding position and reduce the chance of suffering from myopia due to incorrect pen holding habits.

[0085] It should be understood that some users hold the stylus in the right position but with the wrong pen-holding posture when using it. In some embodiments, the wrong pen-holding postures include sliding into the tiger's mouth, hooking the wrist, squeezing the fingers, stretching the fingers, pinching the fingers, and wrapping the thumb inside. Among them, sliding into the tiger's mouth means that the thumb is closer to the pen tip than the index finger, and the pen slides into the tiger's mouth. In this pen-holding posture, it is easy to rub out a lump of flesh on the middle finger; hooking the wrist means that the arm, forearm and wrist are curved. When writing in this pen-holding posture for a long time, the fingers and wrists are prone to soreness; finger squeezing means that the thumb and index finger squeeze the pen from the side; finger stretching means that the thumb and index finger are stretched very long and flat, which is not conducive to the finger force; pinching the fingers means that the thumb and index finger pinch the pen with the fingertips; the wrapping thumb means that the thumb wraps the pen and extends into the index finger. In this pen-holding posture, there is basically no space for the pen-holding finger to exert force, and it is not easy to write. The wrong pen-holding posture will affect the user's sitting posture. Writing for a long time with the wrong pen-holding posture may cause the user to hunch over or become nearsighted.

[0086] In order to solve the above problems, the present application provides the following embodiments: Figure 6 A schematic diagram of the structure of another stylus is shown.

[0087] exist Figure 4 On the basis of the stylus shown, the stylus provided by the present application also includes a plurality of third sensors. A plurality of third small holes are arranged between a first position where a plurality of first small holes are arranged and a second position where a plurality of second small holes are arranged. The contour formed by the plurality of third small holes is a target shape. The target shape conforms to the ergonomic form of the user when contacting the pen shaft in a target pen holding posture. The plurality of third sensors are located in the plurality of third small holes and the detection signals received and sent by the third sensors can pass through the third small holes.

[0088] For example, Figure 6 As shown, the target shape is an arc.

[0089] It should be understood that the "target pen holding posture" in the above scheme refers to a pen holding posture that can keep the fingers and wrists relaxed and avoid hand fatigue and injury during a long period of writing with a writing pen. It can be understood as a correct pen holding posture. In some embodiments, the target pen holding posture includes a dynamic three-finger grip, a dynamic four-finger grip, a side three-finger grip, and a side four-finger grip. Among them, the dynamic three-finger grip means that the stylus is fixed by the thumb, index finger and middle finger, and the thumb and index finger hold the bottom of the pen tip. The thumb and index finger form an elliptical open space, the ring finger and the little finger are slightly bent toward the palm, and the little finger is placed on the table in a comfortable state. The wrist is slightly bent backwards, and the forearm is naturally placed on the table; the fingers are held about 1.5-2cm away from the tip of the pen, and the upper part of the pen tip is placed near the third knuckle of the index finger, and it cannot be placed at the base of the thumb. The dynamic four-finger grip is very similar to the dynamic three-finger grip, except that the dynamic four-finger grip uses the thumb, index finger, and middle finger pulps, and the inner side of the last knuckle of the ring finger to control the pencil. The side three-finger grip is when the thumb crosses over the inside of the pen and is tucked into the side of the index finger, the index finger pulp and the last knuckle of the middle finger are against the pen, and the tiger's mouth is half closed. The side four-finger grip is very similar to the side three-finger grip, when the thumb crosses over the inside of the pen and is tucked into the side of the index finger, the index finger and middle finger pulps, and the inner side of the last knuckle of the ring finger are against the pen, and the tiger's mouth is half closed.

[0090] It should also be understood that, like the plurality of first sensors, a plurality of third sensors may be disposed in the plurality of third small holes through a support frame, or the plurality of third sensors may be disposed on the surface of the pen core. The relative positional relationship between the third sensor and the third small hole may be referred to Figure 2 In (b), the arrangement of the plurality of first small holes is a straight line arrangement, while the arrangement of the plurality of third small holes is an arc arrangement. Correspondingly, the arrangement of the plurality of third sensors is different from the arrangement of the plurality of first sensors.

[0091] It should also be understood that the shape of the third small hole is not limited in the present application. In some embodiments, the shape of the third small hole includes at least one of a circle, a rhombus, a rectangle, a triangle, and a parallelogram. The shape of the third small hole may be the same as or different from the shape of the first small hole and the shape of the second small hole. It should also be understood that the number of the third small holes is not limited in the present application, and the number Q of the third small holes is a positive integer. In some embodiments, when the number of the third small holes is small, a third small hole with a larger cross-section may be provided, so that the third sensor can more accurately detect whether the user is holding the stylus in the correct pen-holding posture.

[0092] In order to more clearly illustrate the technical solutions provided in the embodiments of the present application, the present application provides the following Figure 7 The specific steps shown introduce the technical solution in this application.

[0093] Step 701: When the user holds the stylus pen without covering the second small holes, the controller controls the third sensors to emit detection signals.

[0094] Step 702: The controller is used to detect whether the user blocks the plurality of third small holes when holding the stylus based on the detection signals emitted by the plurality of third sensors and the detection signal received from at least one of the plurality of third small holes.

[0095] Step 703, when the user covers the multiple third small holes when holding the stylus, the controller is used to control the voice output device in the stylus to output a first excitation signal, and the first excitation signal is used to stimulate the user to hold the stylus in a correct pen-holding posture.

[0096] Step 704, when the user does not completely cover the plurality of third small holes when holding the stylus, the controller is used to control the alarm device to output a third warning signal, and the third warning signal is used to prompt the user that the user is not holding the stylus in a correct pen-holding posture.

[0097] It should be understood that the third sensor in the above scheme is the same as the first sensor. The third sensor is a distance sensor, which includes any one of an ultrasonic sensor, a radar sensor, an infrared sensor and a laser sensor, and the corresponding detection signal is an ultrasonic signal, an electromagnetic wave signal, an infrared signal and a laser signal.

[0098] In the above technical solution, a plurality of third small holes are arranged between the first position and the second position of the pen holder in the stylus, and a plurality of third sensors are arranged in the plurality of third small holes, and the detection signal received and sent by the distance sensor in the third small hole can pass through the third small hole. When the user holds the stylus without blocking the plurality of first small holes and the plurality of second small holes, it is determined whether the user blocks the plurality of third small holes when holding the stylus. Since the contour formed by the plurality of third small holes is a target shape, the target shape conforms to the ergonomic shape when the user contacts the pen holder in the target pen holding posture, and the target pen holding posture is a correct pen holding posture, therefore, the above solution is relative to determining whether the user holds the stylus in the correct pen holding posture when the user holds the stylus without approaching the pen tip and not away from the pen tip. When the user holds the stylus in the correct pen holding posture, the controller outputs an excitation signal through the voice output device to encourage the user to continue to maintain the pen holding posture. When the user does not hold the stylus in the correct pen-holding posture, the controller issues an early warning through the alarm device, so that the user can adjust the pen-holding posture. The structure and method design of the writing pen of the present application can be used to correct the pen-holding posture. When the stylus is used for a long time, the user can maintain a relatively correct pen-holding posture and will not develop the habit of incorrect pen-holding posture, thereby reducing the chance of myopia due to incorrect pen-holding habits.

[0099] It should be understood that the implementation principle of "the controller is used to detect whether the user blocks the multiple third small holes when holding the stylus based on the detection signals emitted by the multiple third sensors and the detection signals received from at least one third small holes among the multiple third small holes" in the above scheme is the same as that of "the controller is used to detect whether the user blocks the at least one first small hole when holding the stylus based on the detection signals emitted by the multiple first sensors and the detection signals received from at least one first small hole among the multiple first small holes", which will not be repeated here.

[0100] In a possible implementation, the stylus pen also includes a pressure detection device. After controlling the voice output device in the stylus pen to output a first excitation signal, the controller is also used to: obtain the holding force of the user holding the stylus pen through the pressure detection device; when the holding force is within a preset force range, control the voice output device to output a second excitation signal, and the second excitation signal is used to encourage the user to hold the stylus pen with a correct holding force; when the holding force is not within the preset force range, control the alarm device to output a fourth warning signal, and the fourth warning signal is used to prompt the user that the stylus pen is not held with the correct holding force.

[0101] It should be understood that the "preset force range" in the above solution can be specifically understood as: the range of force with which the user holds the pen when the user writes in the correct pen-holding posture.

[0102] In the above technical solution, when the user holds the stylus pen without blocking the first plurality of small holes, the second plurality of small holes, and the third plurality of small holes, it is determined whether the holding force of the user holding the stylus pen is within the preset force range. The above solution is relative to the situation that when the user holds the stylus pen, the user is not close to the pen tip, is not far from the pen tip, and holds the stylus pen in the correct pen holding posture, it is determined whether the holding force of the user holding the stylus pen is within the preset force range. When the holding force is within the preset force range, the controller controls the voice output device to output a second excitation signal to encourage the user to continue to maintain the holding force; when the holding force is not within the preset force range, the alarm device is controlled to output a warning signal, so that the user can adjust the holding force. The structure and method design of the writing pen of the present application can be used for the correction of holding force. When the stylus pen is used for a long time, the user can maintain a relatively correct holding force and will not develop a wrong holding force habit, thereby reducing the probability of suffering from myopia due to wrong pen holding habits.

[0103] In some embodiments, the pressure detection device is a pressure sensor or pressure-sensitive paper, the pressure sensor is arranged on the inner wall of the pen shaft, a second area on the surface of the pen shaft is wrapped by the pressure-sensitive paper, and the distance between the position in the second area and the pen tip is within a second distance range; the controller is also specifically used to obtain the holding force of the user when holding the stylus through the pressure sensor or the pressure-sensitive paper.

[0104] In the above technical solution, the holding force of the user when holding the stylus pen is obtained more accurately through the pressure sensor or the pressure-sensitive paper.

[0105] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
