[0002] At present, electronic writing devices including handwriting tablets and electromagnetic pens are gradually becoming popular in teaching. The handwriting tablet includes a processor, an electromagnetic signal receiving module and a wireless communication module. The processor is connected to the electromagnetic signal receiving module and the wireless communication module. The processor transmits the handwriting trajectory, pressure data, etc. output by the electromagnetic signal receiving module to the mobile terminal device (for example, the teacher's handwriting tablet) through the wireless communication module. After the mobile terminal device receives the data, it can restore the handwriting. However, a lower reporting rate often results in a poor restoration of the handwriting, and a higher reporting rate will increase the data throughput of the wireless network. When the network condition is poor, smooth writing cannot be maintained, and serious errors such as missing strokes are prone to occur. Summary of the invention

[0023] Figure 1A flow chart of a method for controlling an electronic writing device according to an embodiment of the present disclosure is provided. The electronic writing device includes a handwriting board and a stylus. The method of the present disclosure includes step S101, obtaining sensor data in the stylus. In some embodiments, the stylus may include a touch pen, an electromagnetic pen, etc. It should be understood that this is only exemplary and the present disclosure is not limited thereto.

[0024] The method disclosed herein also includes step S102, calculating the moving speed of the stylus within a preset time from the sensor data. In some embodiments, the moving speed of the stylus within a preset time can be calculated by the stylus. In some embodiments, the moving speed of the stylus within a preset time can be calculated by a handwriting board. In some embodiments, the data can also be uploaded to the cloud for calculation, and the calculated data is then returned by the cloud.

[0025] The method disclosed in the present invention also includes step S103, when the moving speed is less than the first threshold, the reporting rate of the handwriting board is reduced by a preset value; when the moving speed is greater than or equal to the first threshold and less than the second threshold, the reporting rate of the handwriting board is kept unchanged; when the moving speed is greater than or equal to the second threshold, it is determined whether the reporting rate of the handwriting board is less than the first reporting rate threshold, if so, the reporting rate of the handwriting board is increased by a preset value, if not, the reporting rate of the handwriting board is kept unchanged. The reporting rate of the handwriting board refers to the number of times the handwriting board detects writing data per unit time. In some embodiments, when the moving speed is less than the first threshold, it means that the writing of the stylus is slow, the speed of handwriting generation is relatively small, and the reporting rate can also be appropriately reduced by a preset value. In this way, it can ensure that the handwriting is transmitted, and it can also reduce the requirements for the network. Even if the network is not very good, it may be possible to sequentially transmit the handwriting with a small reporting rate. In addition, due to the reduction of the reporting rate, the power consumption of the handwriting board will also be reduced. In some embodiments, the preset value can be set according to the main, for example, 10, 20 or 30. In some embodiments, the first threshold may also be preset and adjustable by the user.

[0026] In some embodiments, when the moving speed is greater than or equal to the first threshold and less than the second threshold, the reporting rate of the handwriting board is kept unchanged. When the moving speed is moderate, the reporting rate of the handwriting board may also be in an appropriate range, so that the handwriting can be smoothly transmitted, and the dependence on the network or the power consumption will not be increased due to the high reporting rate. In some embodiments, when the moving speed is greater than or equal to the second threshold, the speed of handwriting generation is faster. At this time, it is first determined whether the reporting rate of the handwriting board is less than the first reporting rate threshold to avoid adjusting the reporting rate too high. If it is less than the first reporting rate threshold, it indicates that the reporting rate at this time still has room for improvement, and the reporting rate of the handwriting board can be increased by a preset value. If it is not less than the first reporting rate threshold, it indicates that the reporting rate at this time is already high. If it is adjusted upward, it may be too dependent on the network quality, and it is easy to cause strokes to be lost when the network is not good. At this time, the reporting rate of the handwriting board can be kept unchanged, which can also avoid excessive power consumption of the handwriting board due to the high reporting rate. In some embodiments, the second threshold can be preset and the user can adjust it. In some embodiments, the first reporting rate threshold may also be appropriately adjusted according to the network in which the electronic writing device is located and the power consumption of the handwriting tablet, for example, being set to 200 or the like.

[0027] Therefore, the sensor data in the stylus is used to calculate the movement rate of the stylus within a preset time, and then the reporting rate of the handwriting board is adjusted to minimize the impact of factors such as the network on the handwriting. The reporting rate is adjusted according to the needs of handwriting presentation, so that the handwriting can be transmitted smoothly, the requirements for the network can be reduced, and the power consumption of the handwriting board can be reduced.

[0028] like Figure 2 As shown, in some embodiments, the method of the present disclosure further includes step 201, when the reporting rate of the handwriting board is less than the second reporting rate threshold and the moving speed is less than the first threshold, the reporting rate of the handwriting board is kept unchanged, wherein the second reporting rate threshold is less than the first reporting rate threshold. In some embodiments, when the reporting rate of the handwriting board is less than the second reporting rate threshold, although the moving speed is less than the first threshold at this time, that is, the speed of handwriting generation is relatively small, sometimes maintaining a certain reporting rate can more smoothly transmit the handwriting, and avoid the reporting rate being adjusted too low to be unfavorable for timely interaction with an external electronic writing device. In some embodiments, the second reporting rate threshold can be set to the minimum reporting rate allowed for handwriting board interaction.

[0029] like Figure 3As shown, in some embodiments, the method of the present disclosure further includes step 301, determining the network quality, and when the network quality is lower than a preset threshold and the mobile speed is greater than or equal to a first threshold, keeping the reporting rate of the handwriting board unchanged. In some embodiments, when the network quality is not very good, it is sometimes necessary to balance the transmission rate of the handwriting. Although the mobile speed is greater than or equal to the first threshold at this time, the reporting rate of the handwriting board can still be kept unchanged to avoid adjusting the reporting rate too high when the network quality does not meet the high reporting rate.

[0030] In some embodiments, the network quality includes network bandwidth, packet loss rate or delay, etc. In some embodiments, the preset threshold can be pre-set and can be adjusted by the user.

[0031] In some embodiments, Figure 4 As shown, an electronic writing device 400 is shown, and the electronic writing device 400 includes a handwriting board 401 and a stylus 402. In some embodiments, the sensor in the stylus 402 includes an acceleration sensor 4022 and a gyroscope 4023, wherein the acceleration sensor 4022 is used to obtain the acceleration of the stylus 402, and the gyroscope 4023 is used to obtain the angular velocity of the stylus 402. By adopting the combination of the acceleration sensor 4022 and the gyroscope 4023, it is not only conducive to realizing air handwriting recognition, but also can calculate the moving speed of the stylus within a preset time.

[0032] In some embodiments, the stylus pen 402 further includes a microcontroller 4021 and a first communication module 4024 in communication connection with the microcontroller 4021. In some embodiments, the microcontroller 4021 is used to calculate the moving speed of the stylus pen 402 within a preset time, and send the calculated moving speed to the handwriting board 401 through the first communication module 4024. In some embodiments, the stylus pen includes the first communication module 4024, the handwriting board 401 includes a processor 4011 and a second communication module 4012 in communication connection with the processor 4011, the sensor data in the stylus pen 402 is sent through the first communication module 4024 and received by the second communication module 4012 of the handwriting board 401, and the processor 4011 calculates the moving speed of the stylus pen 402 within the preset time. In some embodiments, the handwriting board 401 further includes a signal receiving module 4013. In some embodiments, the signal receiving module 4013 is an electromagnetic induction touch module. In some embodiments, the reporting rate of the handwriting board 401 can be adjusted by the processor 4011 or the signal receiving module 4013.

[0033] In some embodiments, the sensor in the stylus 402 is installed in an area adjacent to the tip of the stylus 402, and the moving speed is the moving speed of the stylus 402 in the horizontal direction. In some embodiments, the tip of the stylus is usually the most suitable part for the user to express the handwriting that the user wants to write, so installing the sensor in the area adjacent to the tip of the stylus can better sense the handwriting that the user wants to write.

[0034] The embodiment of the present disclosure also provides a device 500 for controlling an electronic writing device, wherein the electronic writing device includes a handwriting board and a stylus, and the device 500 includes an acquisition module 501, a calculation module 302, and a control module 303. The acquisition module 501 is configured to acquire sensor data in the stylus. The calculation module 502 is configured to calculate the movement rate of the stylus within a preset time from the sensor data. The control module 503 is configured to reduce the reporting rate of the handwriting board by a preset value when the movement rate is less than a first threshold; when the movement rate is greater than or equal to the first threshold and less than a second threshold, keep the reporting rate of the handwriting board unchanged; when the movement rate is greater than or equal to the second threshold, determine whether the reporting rate of the handwriting board is less than the first reporting rate threshold, if so, increase the reporting rate of the handwriting board by a preset value, if not, keep the reporting rate of the handwriting board unchanged.

[0035] In some embodiments, the control module 503 is further configured to keep the reporting rate of the handwriting board unchanged when the reporting rate of the handwriting board is less than the second reporting rate threshold and the moving speed is less than the first threshold, wherein the second reporting rate threshold is less than the first reporting rate threshold. In some embodiments, the control module 503 is further configured to determine the network quality, and when the network quality is lower than a preset threshold and the moving speed is greater than or equal to the first threshold, keep the reporting rate of the handwriting board unchanged.
