Fig. 1 provides a flowchart of a method of controlling an electronic writing device of an embodiment of the present disclosure. The electronic writing device comprises a writing pad and a writing pen. The method of the present disclosure includes a step S101 of acquiring sensor data in a stylus pen. In some embodiments, the stylus may include a stylus, an electromagnetic pen, and the like, it being understood that this is merely exemplary and the disclosure is not limited thereto.
The method of the present disclosure further includes a step S102 of calculating a moving rate of the stylus pen within a preset time from the sensor data. In some embodiments, calculating the rate of movement of the stylus over a preset time may be performed by the stylus. In some embodiments, calculating the rate of movement of the stylus over a preset time may be performed by a tablet. In some embodiments, the data may also be uploaded to the cloud for computation, and the computed data is then returned by the cloud.
The method of the present disclosure further includes step S103, when the moving rate is smaller than the first threshold, decreasing the report rate of the handwriting board by a preset value; when the moving speed is greater than or equal to a first threshold and smaller than a second threshold, keeping the point reporting rate of the handwriting board unchanged; and when the moving speed is larger than or equal to the second threshold, determining whether the point reporting rate of the handwriting board is smaller than the first point reporting rate threshold, if so, increasing the point reporting rate of the handwriting board by a preset value, and if not, keeping the point reporting rate of the handwriting board unchanged. The point reporting rate of the handwriting board refers to the number of times of detecting written data in unit time of the handwriting board. In some embodiments, when the moving speed is less than the first threshold, it indicates that the writing speed of the stylus is slow, the speed of the handwriting generation is relatively low, and the pointing rate can be reduced by a preset value. This ensures that the writing is transmitted, reduces the requirements on the network, and allows writing with a low hit rate to be transmitted sequentially even when the network is not optimal. In addition, since the report rate is reduced, the power consumption of the handwriting pad is also reduced. In some embodiments, the preset value may be set according to the main, for example, 10, 20, or 30, etc. In some embodiments, the first threshold may also be preset and user adjustable.
In some embodiments, when the moving speed is greater than or equal to the first threshold and less than the second threshold, the hit rate of the handwriting pad is kept unchanged, and when the moving speed is moderate, the hit rate of the handwriting pad may also be in an appropriate range, so that the handwriting can be smoothly transmitted, and the dependence on the network or the increase of power consumption due to the high hit rate is avoided. In some embodiments, when the moving rate is greater than or equal to the second threshold, the speed of generating the handwriting is faster, and at this time, it is determined whether the point reporting rate of the handwriting board is less than the first point reporting rate threshold, so as to avoid adjusting the point reporting rate too high, and if the point reporting rate is less than the first point reporting rate threshold, it indicates that there is room for improving the point reporting rate at this time, the point reporting rate of the handwriting board may be increased by a preset value. If the current time is not less than the first time threshold, the time is indicated to be higher, if the up-regulation is performed again, the dependence on the network quality is too high, strokes are easy to drop when the network is not good, and the time can be kept unchanged, so that the power consumption of the handwriting board is prevented from being too high due to the too high time. In some embodiments, the second threshold may be preset and user adjustable. In some embodiments, the first reporting rate threshold may also be adjusted appropriately, for example, set to 200, according to the network where the electronic writing device is located and the power consumption of the tablet.
Therefore, the moving speed of the handwriting pen in the preset time is calculated through the sensor data in the handwriting pen, the point reporting rate of the handwriting board is further adjusted, the influence of factors such as a network on the handwriting is minimized, the point reporting rate is adjusted according to the requirement of the handwriting presentation, the handwriting can be smoothly transmitted, the requirement on the network can be lowered, and the power consumption of the handwriting board is reduced.
As shown in FIG. 2, in some embodiments, the method of the present disclosure further includes step 201, when the hit rate of the handwriting board is less than a second hit rate threshold and the moving rate is less than the first threshold, keeping the hit rate of the handwriting board unchanged, wherein the second hit rate threshold is less than the first hit rate threshold. In some embodiments, when the hit rate of the handwriting pad is less than the second hit rate threshold, although the moving speed is less than the first threshold, i.e. the speed of the handwriting is relatively low, sometimes the handwriting can be transmitted more smoothly by maintaining a certain hit rate, and the problem that the hit rate is too low to facilitate timely interaction with the external electronic writing device is avoided. In some embodiments, the second reporting rate threshold may be set to a minimum reporting rate allowed for the handwriting pad interaction.
As shown in fig. 3, in some embodiments, the method of the present disclosure further includes step 301 of determining a network quality, and when the network quality is lower than a preset threshold and the moving speed is greater than or equal to a first threshold, keeping the hit rate of the handwriting pad unchanged. In some embodiments, it is sometimes desirable to balance the transmission rate of the handwriting when the network quality is not good. Although the moving speed is larger than or equal to the first threshold value at this time, the point reporting rate of the handwriting board can still be kept unchanged, so as to avoid that the point reporting rate is adjusted too high under the condition that the network quality does not meet the high point reporting rate.
In some embodiments, the network quality includes network bandwidth, packet loss rate or delay, and the like. In some embodiments, the preset threshold may be preset and user adjustable.
In some embodiments, as shown in FIG. 4, an electronic writing device 400 is shown, the electronic writing device 400 including a tablet 401 and a stylus 402. In some embodiments, the sensors in the stylus 402 include an acceleration sensor 4022 and a gyroscope 4023, wherein the acceleration sensor 40 is used to obtain an acceleration of the stylus 402 and the gyroscope 4023 is used to obtain an angular velocity of the stylus 402. By adopting the combination of the acceleration sensor 4022 and the gyroscope 4023, not only can the in-air handwriting recognition be realized, but also the moving rate of the stylus within the preset time can be calculated.
In some embodiments, stylus 402 also includes a microcontroller 4021 and a first communication module 4024 communicatively coupled to microcontroller 4021. In some embodiments, the microcontroller 4021 is configured to calculate a moving rate of the stylus pen 402 within a preset time, and transmit the calculated moving rate to the tablet 401 through the first communication module 4024. In some embodiments, the stylus includes a first communication module 4024, the tablet 401 includes a processor 4011 and a second communication module 4012 communicatively connected to the processor 4011, the sensor data in the stylus 402 is transmitted through the first communication module 4024 and received by the second communication module 4012 of the tablet 401, and the rate of movement of the stylus 402 over a preset time is calculated by the processor 4011. In some embodiments, handwriting pad 401 also includes signal receiving module 4013. In some embodiments, the signal receiving module 4013 is an electromagnetic induction touch module. In some embodiments, the hit rate of handwriting pad 401 may be adjusted by processor 4011 or signal receiving module 4013.
In some embodiments, the sensor in stylus 402 is mounted in an area adjacent to the tip of stylus 402, and the rate of movement is the rate of movement of stylus 402 in the horizontal direction. In some embodiments, the stylus is typically the portion that is most suitable for the user to express the intended writing, and therefore mounting the sensor adjacent to the stylus allows a better sense of the intended writing.

The control module 503 is configured to reduce the hit rate of the handwriting board by a preset value when the moving rate is smaller than a first threshold; when the moving speed is greater than or equal to a first threshold and smaller than a second threshold, keeping the point reporting rate of the handwriting board unchanged; and when the moving speed is larger than or equal to the second threshold, determining whether the point reporting rate of the handwriting board is smaller than the first point reporting rate threshold, if so, increasing the point reporting rate of the handwriting board by a preset value, and if not, keeping the point reporting rate of the handwriting board unchanged.
In some embodiments, control module 503 is further configured to keep the point rate of the handwriting pad unchanged when the point rate of the handwriting pad is less than a second point rate threshold and the movement rate is less than the first threshold, wherein the second point rate threshold is less than the first point 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 hit rate of the handwriting pad unchanged.
