Detailed implementation manners

[0038] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] Please refer to Figures 1 - 5 , Figure 1 Schematic diagram of the structure when the interaction device in an embodiment of the present application is placed horizontally and the user's writing posture conforms to a predetermined standard; Figure 2 Schematic diagram of the structure when the interaction device in an embodiment of the present application is placed vertically and the user's writing posture conforms to a predetermined standard; Figure 3 Schematic diagram of the structure when the interaction device in an embodiment of the present application is placed horizontally and the user's writing posture does not conform to a predetermined standard; Figure 4 Schematic diagram of the structure when the interaction device in an embodiment of the present application is placed vertically and the user's writing posture does not conform to a predetermined standard; Figure 5 Schematic diagram of the structure of the user's writing posture when the user is lying down in an embodiment of the present application. It can be understood that during the process of the user using the stylus 100, the user's writing posture can but is not limited to appearing as Figures 1 - 5the situations shown, and users may have bad habits such as being relatively close to the interaction device 200, lying on the desktop to write, not facing the touch screen 210 of the interaction device 200 directly when writing, or lying down, etc., resulting in Figures 3 - 5 the situations shown, which will cause the user's eyesight to decline and the spine to be damaged.

[0040] Please refer to Figures 6 - 7 , Figure 6 which is a schematic structural diagram of a stylus in an embodiment of the present application; Figure 7 which is a schematic framework structural diagram of a stylus and an interaction device in an embodiment of the present application.

[0041] As Figures 6 - 7 shown, the interaction system includes a stylus 100 and an interaction device 200.

[0042] The stylus 100 is used for the user to interact with the interaction device 200, such as performing touch interactions, writing, annotation and other operations with the interaction device 200 through the stylus 100, which can be but is not limited to these.

[0043] The stylus 100 includes an attitude sensor 110, an inclination angle detection module 120 and a first main control module 130.

[0044] The attitude sensor 110 is used to output the attitude data of the stylus 100. The attitude sensor 110 may include a six-axis inertial measurement unit, and the six-axis inertial measurement unit is used to output the acceleration data of at least one axis among the X / Y / Z axes, and may also output the acceleration data after combining and processing the acceleration data of the X / Y / Z axes; the six-axis inertial measurement unit is also used to output the yaw, pitch, and roll angular velocity data, and may also output the angular velocity data after combining and processing the yaw, pitch, and roll angular velocity data. Of course, the attitude sensor 110 may also include a three-axis accelerometer and a gyroscope. The three-axis accelerometer is used to output the acceleration data of at least one axis among the X / Y / Z axes, and may also output the acceleration data after combining and processing the acceleration data of the X / Y / Z axes; the gyroscope is used to output the yaw, pitch, and roll angular velocity data, and may also output the angular velocity data after combining and processing the yaw, pitch, and roll angular velocity data.

[0045] The inclination angle detection module 120 is used to transmit a downlink signal to the touch screen 210 of the interaction device 200 to cooperate with the touch screen 210 of the interaction device 200 (introduced below) to determine the writing inclination angle of the stylus 100. It should be noted that the writing inclination angle of the stylus 100 can be determined after being calculated by the first main control module 130 of the stylus 100, or can be determined after being calculated by the second main control module 230 of the interaction device 200 (introduced below).

[0046] The first main control module 130 serves as the main controller inside the stylus 100. The first main control module 130 is electrically connected to the attitude sensor 110. The first main control module 130 obtains the attitude data of the attitude sensor 110 through the data bus. The first main control module 130 can communicate with the communication module 220 (introduced below) of the interaction device 200 through wireless communication such as Bluetooth and WIFI, so as to transmit the attitude data.

[0047] The first main control module 130 serves as the main controller inside the stylus 100. The first main control module 130 is also electrically connected to the tilt angle detection module 120. The first main control module 130 controls the tilt angle detection module 120 to transmit a downlink signal to the touch screen 210 of the interaction device 200 through the data bus.

[0048] Specifically, the tilt angle detection module 120 includes a coder 121, a first electrode 122, and a second electrode 123; the coder 121 is electrically connected to the first main control module 130, the first electrode 122 is electrically connected to the coder 121, and the second electrode 123 is electrically connected to the coder 121. The first main control module 130 controls the coder 121 to drive the first electrode 122 and the second electrode 123 to transmit a downlink signal to the touch screen 210 of the interaction device 200, so as to cooperate with the touch screen 210 of the interaction device 200 to determine the writing tilt angle of the stylus 100.

[0049] As Figure 7 shown, the stylus 100 further includes a touch device 140.

[0050] The touch device 140 is used to output the position data of the stylus 100. In other words, the touch device 140 can detect the pen-holding position on the body of the stylus 100 by the user and generate corresponding position data.

[0051] The first main control module 130 serves as the main controller inside the stylus 100. The first main control module 130 is also electrically connected to the touch device 140. The first main control module 130 obtains the position data of the touch device 140 through the data bus. The first main control module 130 can communicate with the communication module 220 of the interaction device 200 through wireless communication such as Bluetooth and WIFI, so as to transmit the position data.

[0052] The first main control module 130 is further configured to determine whether the user's pen-holding position meets a predetermined standard according to the position data.

[0053] Specifically, the touch device 140 is a capacitive touch flexible circuit board 141. The capacitive touch flexible circuit board 141 is arranged inside the body of the stylus 100. The capacitive touch flexible circuit board 141 is suitable for generating position data through the capacitance change of its different touch areas 141a when the user holds the body of the stylus 100.

[0054] For example, please refer to Figure 8 , Figure 8 which is a partial exploded structural schematic diagram of a stylus in an embodiment of the present application. As Figure 8 shown, the capacitive touch flexible circuit board 141 is arranged in a ring around the axis of the stylus 100 (i.e., the direction where the axis is located), and the capacitive touch flexible circuit board 141 is divided into multiple touch areas 141a. When the user holds the body of the stylus 100, the capacitive touch flexible circuit board 141 can generate position data through the capacitance changes of its different touch areas 141a, so as to realize the function of detecting the approach of the human hand. Usually, it is preset that when the user holds the pen in a normal pen-holding posture, the position of the human hand on the body of the stylus 100 should fall on the area of the body corresponding to the capacitive touch flexible circuit board 141, and at the same time, the positions of the thumb, index finger, and middle finger of the human hand on the body of the stylus 100 should respectively fall on three different and spaced positions on the body. Therefore, it can be preset that when the user holds the pen in a normal pen-holding posture, the capacitive touch flexible circuit board 141 can detect three touch areas 141a with relatively large capacitance value changes, and the three touch areas 141a have a certain distance in space. At this time, the user's pen-holding position meets the predetermined standard. On the contrary, if the capacitive touch flexible circuit board 141 detects less than or more than three touch areas 141a with relatively large capacitance value changes, then the user's pen-holding position does not meet the predetermined standard; if the distance between the three touch areas 141a with relatively large capacitance value changes detected by the capacitive touch flexible circuit board 141 is small (for example, three continuously arranged touch areas 141a), then the user's pen-holding position also does not meet the predetermined standard.

[0055] Please refer to Figure 9 , Figure 9 which is a structural schematic diagram of the capacitive touch flexible circuit board laid out flat in an embodiment of the present application. As can be seen from Figure 9 , the capacitive touch flexible circuit board 141 is divided into 6 rows * 6 columns of touch areas 141a. As described above, usually when the user holds the pen in a normal pen-holding posture, the positions of the thumb, index finger, and middle finger of the human hand on the body of the stylus 100 should respectively fall on three different and spaced positions on the body, which also corresponds to the three touch areas 141a with relatively large capacitance value changes detected by the capacitive touch flexible circuit board 141 being spaced apart from each other. In the specific implementation process, if it is detected that the capacitance value changes of less than three touch areas 141a are relatively large, then the user's pen-holding position is too high or too low, and the pen-holding position does not meet the predetermined standard; if it is detected that the capacitance value changes of the touch areas 141a in adjacent rows or columns are relatively large, then the thumb, index finger, and middle finger of the human hand are too close to each other, and the pen-holding position does not meet the predetermined standard. It should be noted that the capacitive touch flexible circuit board 141 is divided into as Figure 9The 6 rows * 6 columns of touch areas 141a shown are just one example. If more precise detection is needed, the capacitive touch flexible circuit board 141 can be divided into more touch areas 141a.

[0056] Based on the stylus 100 provided by the embodiments of the present application, the attitude sensor 110 is used to output the attitude data of the stylus 100, and the tilt angle detection module 120 is used to cooperate with the touch screen 210 of the interaction device 200 to determine the writing tilt angle of the stylus 100. The first main control module 130 determines whether the user's writing attitude meets the predetermined standard according to the attitude data and the writing tilt angle, and when it is determined that the user's writing tilt angle does not meet the predetermined standard, provides a reminder message to the user to urge the user to adjust to a writing attitude that meets the predetermined standard in a timely manner.

[0057] As Figure 7 shown, the interaction device 200 is an integrated device that manipulates and realizes human-computer interaction operations on the content presented on the touch screen 210 through touch technology. The interaction device 200 is used to display notes, information, applications, pictures, videos, etc. that need to be presented during learning and writing; the interaction device 200 can include, but is not limited to, an interactive flat panel or a learning machine.

[0058] The interaction device 200 includes a touch screen 210, a communication module 220, and a second main control module 230.

[0059] The touch screen 210 can be a capacitive screen. The touch screen 210 receives the downlink signal emitted by the tilt angle detection module 120 of the stylus 100 by contacting the stylus 100, so as to cooperate with the tilt angle detection module 120 of the stylus 100 to determine the writing tilt angle of the stylus 100; the touch screen 210 can also accept the control of the second main control module 230 to display corresponding content.

[0060] The communication module 220 is used to communicate with the first main control module 130 of the stylus 100, so as to realize the transmission of the above-mentioned attitude data and position data. Among them, the communication module 220 can include, but is not limited to, wireless communication units such as Bluetooth and WIFI.

[0061] The second main control module 230 serves as the main controller inside the interactive device 200. The second main control module 230 is electrically connected to the touch screen 210. The second main control module 230 can obtain the relevant data for calculating the writing tilt angle through the data bus (such as the first capacitor C1 formed between the first electrode 122 and the touch screen 210, the second capacitor C2 formed between the second electrode 123 and the touch screen 210, and the distance d between the first capacitor C1 and the second capacitor C2 on the writing surface of the touch screen 210). The second main control module 230 is also electrically connected to the communication module 220. The second main control module 230 can obtain the posture data and position data output by the communication module 220 through the data bus.

[0062] It is understandable that when using the stylus 100, the user may have bad habits such as lying down, being close to the interactive device 200, lying on the table to write, or not facing the touch screen 210 of the interactive device 200 when writing (such as Figures 3 - 5 Therefore, in order to correct the user's bad habits, the stylus pen 100 can be used as a judgment end to judge whether the user's writing posture meets the predetermined standard according to the posture data and the writing tilt angle, or the interactive device 200 can be used as a judgment end to judge whether the user's writing posture meets the predetermined standard according to the posture data and the writing tilt angle.

[0063] For example, when the stylus pen 100 is used as a judgment terminal to judge whether the user's writing posture meets the predetermined standard according to the posture data and the writing tilt angle, the first main control module 130 of the stylus pen 100 may calculate the posture data, the second main control module 230 of the interactive device may calculate the relevant data of the writing tilt angle to determine the writing tilt angle, and the second main control module 230 of the interactive device 200 transmits the processed writing tilt angle to the first main control module 130 of the stylus pen 100 through the communication module 220 of the interactive device 200, and finally the first main control module 130 of the stylus pen 100 judges whether the user's writing posture meets the predetermined standard according to the acquired posture data and the writing tilt angle. Alternatively, the first main control module 130 of the stylus pen 100 calculates the posture data, and the second main control module 230 of the interactive device 200 directly transmits the relevant data of the writing tilt angle to the first main control module 130 of the stylus pen 100 through the communication module 220 of the interactive device 200. The first main control module 130 of the stylus pen 100 then calculates the relevant data of the writing tilt angle to determine the writing tilt angle. Finally, the first main control module 130 of the stylus pen 100 determines whether the user's writing posture meets the predetermined standard based on the posture data and the writing tilt angle.

[0064] At this time, the stylus 100 further includes a reminder module (not shown in the figure), and the reminder module is electrically connected to the first main control module 130. The first main control module 130 is configured to control the reminder module to provide a reminder message to the user when it is determined that the user's writing posture does not meet the predetermined standard. Among them, the reminder message may include, but is not limited to, voice reminder (in this case, the reminder module includes a speaker) or light reminder (in this case, the reminder module includes an indicator light).

[0065] Of course, the first main control module 130 of the stylus 100 can also determine whether the user's pen-holding position meets the predetermined standard according to the above position data. The first main control module 130 of the stylus 100 calculates the position data, and the first main control module 130 of the stylus 100 determines whether the user's pen-holding position meets the predetermined standard according to the position data. And the first main control module 130 of the stylus 100 is configured to control the reminder module to provide a reminder message to the user when it is determined that the user's pen-holding position does not meet the predetermined standard.

[0066] For another example, when the interaction device 200 is used as a judgment end to determine whether the user's writing posture meets the predetermined standard according to the posture data and the writing data. It can be that the first main control module 130 of the stylus 100 calculates the posture data, and the first main control module 130 of the stylus 100 transmits the processed posture data to the second main control module 230 of the interaction device 200 through the communication module 220 of the interaction device 200. The second main control module 230 of the interaction device 200 calculates the relevant data of the writing tilt angle to determine the writing tilt angle. Finally, the second main control module 230 of the interaction device 200 determines whether the user's writing posture meets the predetermined standard according to the posture data and the writing tilt angle. It can also be that the first main control module 130 of the stylus 100 directly transmits the unprocessed posture data to the second main control module 230 of the interaction device 200 through the communication module 220 of the interaction device 200. The second main control module 230 of the interaction device 200 calculates the unprocessed posture data and the relevant data of the writing tilt angle to determine the writing tilt angle. Finally, the second main control module 230 of the interaction device 200 determines whether the user's writing posture meets the predetermined standard according to the posture data and the writing tilt angle.

[0067] At this time, the interaction device 200 further includes a warning module 240, and the warning module 240 is electrically connected to the second main control module 230. The second main control module 230 is configured to control the warning module 240 to provide a reminder message to the user when it is determined that the user's writing posture does not meet the predetermined standard. Among them, the reminder message may include, but is not limited to, voice reminder (in this case, the warning module 240 includes a speaker) or light reminder (in this case, the warning module 240 includes an indicator light).

[0068] Of course, the second main control module 230 of the interaction device 200 can also determine whether the user's pen-holding position meets a predetermined standard based on the above position data. It can be that the first main control module 130 of the stylus 100 calculates the position data, and the first main control module 130 of the stylus 100 transmits the processed position data to the second main control module 230 of the interaction device 200 through the communication module 220 of the interaction device 200. The second main control module 230 of the interaction device 200 determines whether the user's pen-holding position meets a predetermined standard based on the position data, and the second main control module 230 of the interaction device 200 is used to control the warning module 240 to provide a reminder message to the user when it is determined that the user's pen-holding position does not meet the predetermined standard. It can also be that the first main control module 130 of the stylus 100 directly transmits the unprocessed position data to the second main control module 230 of the interaction device 200 through the communication module 220 of the interaction device 200. The second main control module 230 of the interaction device 200 calculates the unprocessed position data, and the second main control module 230 of the interaction device 200 determines whether the user's pen-holding position meets a predetermined standard based on the obtained position data, and the second main control module 230 of the interaction device 200 is used to control the warning module 240 to provide a reminder message to the user when it is determined that the user's pen-holding position does not meet the predetermined standard.

[0069] It should be noted that when the stylus 100 is used as a judgment end to determine whether the user's writing posture meets a predetermined standard based on the attitude data and the writing tilt angle, the interaction device 200 can also be used as a judgment end to determine whether the user's pen-holding position meets a predetermined standard based on the above position data. When the interaction device 200 is used as a judgment end to determine whether the user's writing posture meets a predetermined standard based on the attitude data and the writing tilt angle, the stylus 100 can also be used as a judgment end to determine whether the user's pen-holding position meets a predetermined standard based on the above position data.

[0070] Based on the interaction device 200 provided in the embodiment of the present application, the communication module 220 is used to transmit the attitude data of the stylus 100 output by the attitude sensor 110 to the second main control module 230. The touch screen 210 is used to cooperate with the tilt angle detection module 120 of the stylus 100 to determine the writing tilt angle of the stylus 100. The second main control module 230 determines whether the user's writing posture meets a predetermined standard based on the attitude data and the writing tilt angle, and provides a reminder message to the user when it is determined that the user's writing tilt angle does not meet the predetermined standard, so as to urge the user to adjust to a writing posture that meets the predetermined standard in time.

[0071] Please refer to Figure 10 , Figure 10Schematic flowchart of a method for monitoring the writing posture of a stylus provided by an embodiment of the present application. Based on the above method for monitoring the writing posture of the stylus 100, it can be but is not limited to being applied in scenarios where the stylus 100 is used in cooperation with an interaction device 200 for learning and writing. As Figure 10 shown, the monitoring method includes steps S101 - S104:

[0072] Step S101, obtain the posture data of the stylus 100.

[0073] In step S101, as described above, the stylus 100 includes a posture sensor 110, and the posture sensor 110 is used to output the posture data of the stylus 100. The posture sensor 110 may include a six-axis inertial measurement unit, and the six-axis inertial measurement unit is used to output the acceleration data of at least one of the X / Y / Z axes, and may also output the acceleration data after combining and processing the acceleration data of the X / Y / Z axes. The six-axis inertial measurement unit is also used to output the yaw, pitch, and roll angular velocity data, and may also output the angular velocity data after combining and processing the yaw, pitch, and roll angular velocity data. Of course, the posture sensor 110 may also include a three-axis accelerometer and a gyroscope. The three-axis accelerometer is used to output the acceleration data of at least one of the X / Y / Z axes, and may also output the acceleration data after combining and processing the acceleration data of the X / Y / Z axes; the gyroscope is used to output the yaw, pitch, and roll angular velocity data, and may also output the angular velocity data after combining and processing the yaw, pitch, and roll angular velocity data. Among them, the posture data includes at least one of acceleration data and angular velocity data.

[0074] Step S102, obtain the writing tilt angle of the stylus 100.

[0075] In step S102, the "writing tilt angle" is the angle between the axis of the stylus 100 and the writing surface of the touch screen 210 of the interaction device 200. As described above, the stylus 100 further includes a tilt angle detection module 120, and the tilt angle detection module 120 is used to transmit a downlink signal to the touch screen 210 of the interaction device 200 to cooperate with the touch screen 210 of the interaction device 200 to determine the writing tilt angle of the stylus 100. It should be noted that the writing tilt angle of the stylus 100 can be determined by calculation through the first main control module 130 of the stylus 100, or can be determined by calculation through the second main control module 230 of the interaction device 200.

[0076] Step S103, determine whether the user's writing posture meets a predetermined standard according to the posture data and the writing tilt angle.

[0077] In step S103, as described above, it can be the stylus 100 as the judgment end to determine whether the user's writing posture meets the predetermined standard according to the attitude data and the writing tilt angle, or it can be the interaction device 200 as the judgment end to determine whether the user's writing posture meets the predetermined standard according to the attitude data and the writing tilt angle. This will not be elaborated here.

[0078] Step S104, if it is determined that the user's writing posture does not meet the predetermined standard, a reminder message is provided to the user.

[0079] In step S104, as described above, when it is determined that the user's writing posture does not meet the predetermined standard, it can be the reminder module of the stylus 100 to provide a reminder message to the user, or it can be the warning module 240 of the interaction device 200 to provide a reminder message to the user, so as to urge the user to adjust to the writing posture that meets the predetermined standard in time. This will not be elaborated here.

[0080] It should be noted that if it is determined that the user's writing posture meets the predetermined standard, no reminder message needs to be provided to the user.

[0081] Based on the writing posture monitoring method of the stylus 100 provided by the embodiments of the present application, by obtaining the attitude data of the stylus 100 and obtaining the writing tilt angle of the stylus 100, and determining whether the user's writing posture meets the predetermined standard according to the attitude data and the writing tilt angle, and when it is determined that the user's writing tilt angle does not meet the predetermined standard, a reminder message is provided to the user to urge the user to adjust to the writing posture that meets the predetermined standard in time.

[0082] Further, please refer to Figure 11 , Figure 11 which is a schematic flow chart of the writing posture monitoring method of the stylus provided by another embodiment of the present application. The above attitude data includes acceleration data. As Figure 11 shown, step S103 includes step S201 and step S202:

[0083] Step S201: If the acceleration data is less than or equal to the first preset value and greater than the second preset value, it is determined that the angle of the tip of the stylus 100 facing upward does not exceed the preset angle threshold, and according to the writing tilt angle of the stylus 100, it is thus determined whether the user's writing posture meets the predetermined standard.

[0084] In step S201, the attitude sensor 110 is used to output acceleration data. Any one of the X / Y / Z axis directions of the attitude sensor 110 is parallel to the axial direction of the stylus 100. By detecting the acceleration data of the attitude sensor 110, the tip orientation of the stylus 100 can be determined. The "angle threshold" represents the maximum angle (acute angle) between the axial direction of the stylus 100 and the horizontal plane when the tip of the stylus 100 is facing up, and initially, it is determined according to the acceleration data that the user's writing posture conforms to the predetermined standard. When the acceleration data is less than or equal to the first preset value and greater than the second preset value, it indicates that the tip of the stylus 100 is facing up normally at this time, and the inclination angle of the stylus 100 is appropriate and not too large. It should be noted that the specific values of the "first preset value / second preset value" are not limited here, and designers can make reasonable designs according to actual needs.

[0085] Step S202: If the acceleration data is less than the second preset value, it is determined that the tip of the stylus 100 is facing down, and according to the writing inclination angle of the stylus 100, it is determined whether the user's writing posture conforms to the predetermined standard.

[0086] It should be noted that when the acceleration data is equal to the second preset value, the axial direction of the stylus 100 is parallel to the horizontal plane at this time.

[0087] Further, please refer to Figure 12 , Figure 12 which is a schematic flowchart of a method for monitoring the writing posture of a stylus provided by another embodiment of the present application. As Figure 12 shown, the above step S201 includes steps S301 - S303:

[0088] Step S301: Obtain the inclination angle threshold corresponding to the acceleration data.

[0089] In step S301, the "inclination angle threshold" represents the maximum angle (acute angle) between the axial direction of the stylus 100 and the writing surface of the touch screen 210 of the interaction device 200 when the tip of the stylus 100 is facing up normally, and further, it is determined according to the writing inclination angle that the user's writing posture conforms to the predetermined standard. It should be noted that the specific value of the "inclination angle threshold" is not limited here, and designers can make reasonable designs according to actual needs.

[0090] Step S302: If the writing inclination angle is less than the inclination angle threshold, it is determined that the user's writing posture does not conform to the predetermined standard.

[0091] In step S302, when the writing inclination angle is less than the inclination angle threshold, it means that the tip of the stylus pen 100 is normally facing upwards. However, it may be due to factors such as the user lying down, being close to the interactive device 200, or writing on the desktop, or not facing the touch screen 210 of the interactive device 200 when writing, resulting in the angle between the axis of the stylus pen 100 and the writing surface of the touch screen 210 of the interactive device 200 being too small. At this time, it is determined that the user's writing posture does not meet the predetermined standard, and a reminder message is provided to the user (it can be the reminder module of the stylus pen 100 that provides the reminder message to the user, or it can be the early warning module 240 of the interactive device 200 that provides the reminder message to the user) to urge the user to promptly adjust to a writing posture that meets the predetermined standard.

[0092] Step S303: Otherwise, it is determined that the user's writing posture meets the predetermined standard.

[0093] In step S303, when the writing inclination angle is greater than or equal to the inclination angle threshold, it means that the tip of the stylus pen 100 is normally facing upward, and the angle between the axis of the stylus pen 100 and the writing surface of the touch screen 210 of the interactive device 200 is appropriate. At this time, it is judged that the user's writing posture meets the predetermined standard, and there is no need to provide reminder information to the user.

[0094] For further information, see Figure 13 , Figure 13 A flowchart of a method for monitoring the writing posture of a stylus pen provided in another embodiment of the present application is shown below. Figure 13 As shown, the above step S301 includes step S401 and step S402:

[0095] Step S401: Pre-store the corresponding relationship between a plurality of acceleration data and a plurality of tilt angle thresholds.

[0096] In step S401, the acceleration data and the tilt angle threshold satisfy a linear function relationship, and a plurality of acceleration data and a plurality of tilt angle thresholds correspond one to one (ie, each acceleration data has a corresponding tilt angle threshold).

[0097] Step S402: Substitute the acceleration data into the corresponding relationship to obtain the corresponding tilt angle threshold.

[0098] It should be noted that, by designing a corresponding tilt angle threshold for each acceleration data through the corresponding relationship, the monitoring accuracy of the posture monitoring method can be effectively improved.

[0099] For further information, see Figure 14 , Figure 14 A flowchart of a method for monitoring the writing posture of a stylus pen provided in another embodiment of the present application is shown below. Figure 14As shown, the above step S202 includes steps S501 - S503:

[0100] Step S501: If the acceleration data is less than the second preset value and greater than or equal to the third preset value, obtain the first inclination angle range corresponding to the acceleration data.

[0101] It should be noted that the specific value of the "third preset value" is not limited here, and the designer can make a reasonable design according to actual needs; the specific range value of the "first inclination angle range" is not limited here, and the designer can make a reasonable design according to actual needs.

[0102] Step S502: If the writing inclination angle exceeds the first inclination angle range, it is determined that the user's writing posture does not meet the predetermined standard.

[0103] In step S502, when the writing inclination angle exceeds the first inclination angle range, it means that the tip of the stylus 100 is facing down normally at this time, but it may be due to factors such as the user being relatively close to the interaction device 200, or lying on the desktop while writing, or not facing the touch screen 210 of the interaction device 200 directly when writing, etc., resulting in the angle between the axis of the stylus 100 and the writing surface of the touch screen 210 of the interaction device 200 exceeding the first inclination angle range. At this time, it is determined that the user's writing posture does not meet the predetermined standard, and a reminder message is provided to the user (it can be the reminder module of the stylus 100 that provides the reminder message to the user, or the warning module 240 of the interaction device 200 that provides the reminder message to the user), so as to urge the user to adjust to a writing posture that meets the predetermined standard in a timely manner.

[0104] Step S503: Otherwise, it is determined that the user's writing posture meets the predetermined standard.

[0105] In step S503, when the writing inclination angle does not exceed the first inclination angle range, it means that the tip of the stylus 100 is facing down normally at this time, and the angle between the axis of the stylus 100 and the writing surface of the touch screen 210 of the interaction device 200 is within the first inclination angle range. At this time, it is determined that the user's writing posture meets the predetermined standard, and no reminder message needs to be provided to the user.

[0106] Furthermore, please refer to Figure 15 , Figure 15 which is a schematic flow diagram of the writing posture monitoring method of the stylus provided by another embodiment of the present application. As Figure 15 shown, the above step S202 includes steps S504 - S506:

[0107] Step S504: If the acceleration data is less than the third preset value and greater than or equal to the fourth preset value, obtain the second inclination angle range corresponding to the acceleration data.

[0108] It should be noted that the specific value of the "fourth preset value" is not limited here, and the designer can make a reasonable design according to actual needs; the specific range value of the "second inclination angle range" is not limited here, and the designer can make a reasonable design according to actual needs.

[0109] Step S505: If the writing inclination angle exceeds the second inclination angle range, it is determined that the user's writing posture does not meet the predetermined standard.

[0110] In step S505, when the writing inclination angle exceeds the second inclination angle range, it indicates that the tip of the stylus 100 is facing down normally at this time. However, due to factors such as the user being relatively close to the interaction device 200, or lying on the desktop while writing, or not facing the touch screen 210 of the interaction device 200 directly when writing, the angle between the axis of the stylus 100 and the writing surface of the touch screen 210 of the interaction device 200 exceeds the second inclination angle range. At this time, it is determined that the user's writing posture does not meet the predetermined standard, and a reminder message is provided to the user (it can be the reminder module of the stylus 100 that provides the reminder message to the user, or the warning module 240 of the interaction device 200 that provides the reminder message to the user) to urge the user to adjust to a writing posture that meets the predetermined standard in a timely manner.

[0111] Step S506: Otherwise, it is determined that the user's writing posture meets the predetermined standard.

[0112] In step S506, when the writing inclination angle does not exceed the second inclination angle range, it indicates that the tip of the stylus 100 is facing down normally at this time, and the angle between the axis of the stylus 100 and the writing surface of the touch screen 210 of the interaction device 200 is within the second inclination angle range. At this time, it is determined that the user's writing posture meets the predetermined standard, and no reminder message needs to be provided to the user.

[0113] It should be noted that when the acceleration data is less than the second preset value (that is, the tip of the stylus 100 is facing down normally), more preset value ranges (such as less than the fourth preset value and greater than or equal to the fifth preset value, less than the fifth preset value and greater than or equal to the sixth preset value) and corresponding inclination angle ranges (such as the third inclination angle range, the fourth inclination angle range) can be designed, which will not be elaborated here. And it can be understood that the more the designed preset value ranges and the corresponding inclination angle ranges are, the higher the monitoring accuracy of this monitoring method is.

[0114] Further, please refer to Figure 16 , Figure 16 which is a schematic flowchart of the writing posture monitoring method of the stylus provided by another embodiment of the present application. As Figure 16 shown, this monitoring method further includes step S105:

[0115] Step S105: Determine whether the user's writing posture conforms to a predetermined standard according to the posture data.

[0116] In step S105, as described above, the stylus 100 can be used as the judgment end to determine whether the user's writing posture conforms to the predetermined standard according to the posture data, or the interaction device 200 can be used as the judgment end to determine whether the user's writing posture conforms to the predetermined standard according to the posture data, which will not be elaborated here.

[0117] Specifically, the posture data includes acceleration data, and the above step S105 specifically includes step S601:

[0118] Step S601: If the acceleration data is greater than the first preset value, it is determined that the upward angle of the tip of the stylus 100 exceeds the preset angle threshold, thereby determining that the user's writing posture does not conform to the predetermined standard.

[0119] In step S601, the posture sensor 110 outputs acceleration data for the user. Any one of the X / Y / Z axis directions of the posture sensor 110 is parallel to the axis of the stylus 100. By detecting the acceleration data of the posture sensor 110, the orientation of the tip of the stylus 100 can be determined. The "angle threshold" represents the maximum included angle (acute angle) between the axis of the stylus 100 and the horizontal plane when the tip of the stylus 100 is upward, and it is initially determined that the user's writing posture conforms to the predetermined standard according to the acceleration data. When the acceleration data is greater than the first preset value, it means that the upward tilt angle of the tip of the stylus 100 is too large at this time (for example, the axis of the stylus 100 is perpendicular or nearly perpendicular to the horizontal plane), and the user is in a lying state. At this time, it is determined that the user's writing posture does not conform to the predetermined standard, and a reminder message is provided to the user (it can be the reminder module of the stylus 100 that provides the reminder message to the user, or the warning module 240 of the interaction device 200 that provides the reminder message to the user) to urge the user to adjust to a writing posture that conforms to the predetermined standard in a timely manner.

[0120] Further, please refer to Figure 17 , Figure 17 which is a schematic flowchart of a method for monitoring the writing posture of a stylus provided by another embodiment of the present application. As Figure 17 shown, the monitoring method further includes step S106 and step S107:

[0121] Step S106: Determine whether the user performs an unconventional operation in a non-writing state according to the posture data.

[0122] In step S106, either the stylus 100 can be used as the judgment end to determine whether the user performs an unconventional operation in the non-writing state according to the attitude data, or the interaction device 200 can be used as the judgment end to determine whether the user performs an unconventional operation in the non-writing state according to the attitude data. Among them, the unconventional operation can include, but is not limited to, actions such as twirling the pen and flicking the pen.

[0123] Step S107: If it is determined that the user performs an unconventional operation in the non-writing state, provide a reminder message to the user.

[0124] In step S107, when it is determined that the user performs an unconventional operation in the non-writing state, either the reminder module of the stylus 100 can provide a reminder message to the user, or the warning module 240 of the interaction device 200 can provide a reminder message to the user, so as to urge the user to stop performing the unconventional operation in the non-writing state in time.

[0125] Specifically, please refer to Figure 18 , Figure 18 which is a schematic flowchart of the writing attitude monitoring method of the stylus 100 provided by another embodiment of the present application. The attitude data includes angular velocity data. As Figure 18 shown, the above step S106 includes step S701 and step S702:

[0126] Step S701: If the magnitude of the angular velocity data is greater than the preset angular velocity value and the direction of the angular velocity data changes periodically, it is determined that the user performs an unconventional operation in the non-writing state.

[0127] In step S701, the attitude sensor 110 is used to output angular velocity data. Taking the Z-axis direction of the attitude sensor 110 being parallel to the axial direction of the stylus 100 as an example, if at this time the angular velocity in the X-axis direction or the Y-axis direction of the attitude sensor 110 or the maximum value after weighting the angular velocities in these two axis directions according to a specific algorithm is greater than the preset angular velocity value, and the angular velocity of the attitude sensor 110 is in a periodic change process, it indicates that the user is twirling the pen or flicking the pen at this time. It is determined that the user performs an unconventional operation in the non-writing state, and a reminder message is provided to the user (either the reminder module of the stylus 100 can provide a reminder message to the user, or the warning module 240 of the interaction device 200 can provide a reminder message to the user), so as to urge the user to stop performing the unconventional operation in the non-writing state in time.

[0128] Step S702: Otherwise, it is determined that the user does not perform an unconventional operation in the non-writing state.

[0129] In step S702, the attitude sensor 110 is used to output angular velocity data. Taking the case where the Z-axis direction of the attitude sensor 110 is parallel to the axial direction of the stylus 100 as an example, if the angular velocity in the X-axis direction or the Y-axis direction of the attitude sensor 110, or the maximum value after weighting the angular velocities in these two axis directions according to a specific algorithm, is less than the preset angular velocity value, or the angular velocity of the attitude sensor 110 is in a non-periodic change process, it indicates that the user is not twirling or flicking the pen at this time. It is determined that the user does not perform an unconventional operation in the non-writing state, and no reminder information needs to be provided to the user.

[0130] Further, please refer to Figure 19 , Figure 19 which is a schematic flowchart of a writing attitude monitoring method for a stylus provided by another embodiment of the present application. As Figure 19 shown, the monitoring method further includes steps S108 - S110:

[0131] Step S108: Obtain the position data of the stylus 100.

[0132] In step S108, as described above, the stylus 100 further includes a touch device 140, and the touch device 140 is used to output the position data of the stylus 100. The touch device 140 can be a capacitive touch flexible circuit board 141. The capacitive touch flexible circuit board 141 is disposed inside the body of the stylus 100. The capacitive touch flexible circuit board 141 is adapted to generate position data by the capacitance change of its different touch areas 141a when the user holds the body of the stylus 100.

[0133] Step S109: Determine whether the user's pen-holding position conforms to a predetermined standard according to the position data.

[0134] In step S109, as described above, it can be that the stylus 100 is used as the judgment end to determine whether the user's pen-holding position conforms to the predetermined standard according to the position data, or it can be that the interaction device 200 is used as the judgment end to determine whether the user's pen-holding position conforms to the predetermined standard according to the position data, which will not be elaborated here.

[0135] Step S110: If it is determined that the user's pen-holding position does not conform to the predetermined standard, provide reminder information to the user.

[0136] In step S110, as described above, if the capacitive touch flexible circuit board 141 can detect three touch areas 141a with relatively large changes in capacitance values, and the three touch areas 141a are spatially separated by a certain distance, it can be determined at this time that the user's pen-holding position meets the predetermined standard. Conversely, if the capacitive touch flexible circuit board 141 detects less than or more than three touch areas 141a with relatively large changes in capacitance values, it can be determined at this time that the user's pen-holding position does not meet the predetermined standard; if the capacitive touch flexible circuit board 141 detects three consecutive touch areas 141a with relatively large changes in capacitance values, it can also be determined at this time that the user's pen-holding position does not meet the predetermined standard. When it is determined that the user's pen-holding position does not meet the predetermined standard, it can be that the reminder module of the stylus 100 provides a reminder message to the user, or it can be that the warning module 240 of the interaction device 200 provides a reminder message to the user to urge the user to adjust to a pen-holding position that meets the predetermined standard in a timely manner.
