In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention 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 invention, but not to limit the present invention.

The specific implementation of the present invention is described in detail below in conjunction with specific embodiments:

Example 1:

FIG. 1 shows the implementation process of the method for reminding the holding posture of a writing pen provided by the first embodiment of the present invention. For the convenience of description, only the parts related to the embodiment of the present invention are shown, and the details are as follows:

In step S101 , the touch pressure of the touch point when the user of the writing pen is holding the pen is acquired in real time by the pressure sensor of the writing pen, and the touch pressure of the touch point is compared with a preset pressure range.

The embodiment of the present invention is suitable for an intelligent writing pen, and the writing pen is provided with a pressure sensor and a touch sensor. In this embodiment of the present invention, the preset pressure range is a pre-acquired value of the touch pressure range of the user of the writing pen when he writes with the correct posture of holding the pen. Since the user of the writing pen only holds the writing pen in his hand (without writing) , the pressure (touch pressure) of the contact point between the writing pen user's hand and the writing pen is relatively small, while the writing pen user's touch pressure increases significantly when writing. The touch pressure of the touch point when the pen is used, and then the touch pressure of the touch point is compared with the preset pressure range.

In the embodiment of the present invention, preferably, the pressure sensor of the writing pen is activated only when it is detected that the user of the writing pen is about to use the writing pen to write. duration of use. When detecting whether the writing pen user will use the writing pen to write, preferably, whether the writing pen user will use the writing pen to write is determined by the gravity sensor of the writing pen, thereby improving the accuracy of judging the use state of the writing pen, specifically, When the gravity sensor senses that the refill of the writing pen is facing downward, it indicates that the user of the writing pen will use the writing pen to write. If the writing pen is provided with a pen cover, preferably, according to whether the pen cover of the writing pen is taken down, it is determined whether the writing pen user will use the writing pen to write, thereby simplifying the detection process of the writing pen use state. If the refill of the writing pen is a retractable refill, preferably, whether the user of the writing pen will use the writing pen to write is determined according to the expansion and contraction of the writing pen refill, thereby simplifying the detection process of the writing pen's use state.

In step S102, when the touch pressure of the touch point is within the preset pressure range, the touch area of the touch point is acquired through the touch sensor of the writing pen, and the touch area is compared with the preset area range.

In the embodiment of the present invention, the preset area range is the range value of the touch area of the touch point acquired in advance when the user of the writing pen writes with the correct posture of holding the pen, and the touch pressure of the touch point is within the preset pressure range, indicating that The writing pen user is currently using the writing pen to write, otherwise, it indicates that the user just holds the writing pen in his hand and does not write. When the writing pen user is using the writing pen to write at this time, considering that the children who are learning to write generally use the wrong gesture of holding the pen when they are writing, the pen is held by the whole hand, resulting in a larger touch area of the touch point. Therefore, in the Here, the touch area of the touch point is obtained through the touch sensor of the writing pen, and then the touch area is compared with the preset area range.

In step S103, when the touch area is not within the preset area range, remind the user of the writing pen to hold the pen gesture.

In the embodiment of the present invention, when the touch area is not within the preset area range, it indicates that the writing pen user does not use the correct pen holding posture to write, and at this time, the writing pen user is reminded of the pen holding posture. Specifically, a vibrator in the writing pen can remind the writing pen user that the posture of holding the pen is wrong.

In order to more accurately detect the wrong gesture of the user of the writing pen, before acquiring the touch pressure of the touch point when the user of the writing pen is holding the pen in real time through the pressure sensor of the writing pen, it is preferable to obtain a preset number of times that the user of the writing pen is holding the pen. For the calibrated touch pressure and touch area, set the maximum and minimum touch pressures of the writing pen user after calibration of the pen holding posture for the preset number of times as the maximum and minimum values of the preset pressure range, respectively, and set the preset number of times The maximum and minimum values of the touch area of the writing pen user after calibration of the holding posture of the pen are respectively set as the maximum and minimum values of the preset area range, so as to accurately obtain the range of the touch pressure and the touch area when the writing pen user holds the pen correctly. value.

In the embodiment of the present invention, the touch pressure of the touch point when the user of the writing pen is holding the pen is acquired in real time by the pressure sensor of the writing pen, and the touch pressure of the touch point is compared with the preset pressure range. When the touch pressure of the touch point is within the preset pressure range When the pressure is within the range, the touch area of the touch point is obtained through the touch sensor of the writing pen, and the touch area is compared with the preset area range. When the touch area is not within the preset area range, the pen user's holding posture is reminded , thereby realizing the intelligence of the writing pen, and through the automatic reminder of the writing pen, the user of the writing pen can correct the posture of holding the pen in time.

Embodiment 2:

FIG. 2 shows the implementation process of the method for reminding the holding posture of the writing pen provided by the second embodiment of the present invention. For the convenience of description, only the part related to the embodiment of the present invention is shown, and the details are as follows:

In step S201, the touch pressure of the touch point when the user of the writing pen is holding the pen is acquired in real time by the pressure sensor of the writing pen, and the touch pressure of the touch point is compared with a preset pressure range.

The embodiment of the present invention is suitable for an intelligent writing pen, and the writing pen is provided with a pressure sensor and a touch sensor. In the embodiment of the present invention, when the writing pen user only holds the writing pen in his hand (without writing), the pressure (touch pressure) of the contact point between the writing pen user's hand and the writing pen is relatively small, while the writing pen user is in the When writing, the touch pressure increases significantly. Therefore, the pressure sensor of the writing pen first obtains the touch pressure of the touch point when the user holds the pen in real time through the pressure sensor of the writing pen, and then compares the touch pressure of the touch point with the preset pressure range. Specifically, when the cap of the writing pen is taken off, it can be determined that the user of the writing pen is ready to use the writing pen. If the refill of the writing pen is a retractable refill, the writing pen can be judged according to the expansion and contraction of the writing pen refill. Whether the user is ready to use a stylus.

In step S202, when the touch pressure of the touch point is within the preset pressure range, the touch area of the touch point is acquired through the touch sensor of the writing pen, and the touch area is compared with the preset area range.

In the embodiment of the present invention, the preset area range is the range value of the touch area of the touch point acquired in advance when the user of the writing pen writes with the correct posture of holding the pen, and the touch pressure of the touch point is within the preset pressure range, indicating that The writing pen user is currently using the writing pen to write, otherwise, it indicates that the user just holds the writing pen in his hand and does not write. When the writing pen user is using the writing pen to write at this time, considering that the children who are learning to write generally use the wrong pen-holding posture to hold the pen through the whole hand, resulting in a larger touch area of the touch point. Therefore, we First, the touch area of the touch point is obtained through the touch sensor of the writing pen, and then the touch area is compared with the preset area range.

In step S203, when the touch area is not within the preset area range, the writing pen user is reminded of the gesture of holding the pen.

In the embodiment of the present invention, when the touch area is not within the preset area range, it indicates that the writing pen user does not use the correct pen holding posture to write, and at this time, the writing pen user is reminded of the pen holding posture. Specifically, a vibrator in the writing pen can remind the writing pen user that the posture of holding the pen is wrong.

In order to more accurately detect the wrong gesture of the user of the writing pen, before acquiring the touch pressure of the touch point when the user of the writing pen is holding the pen in real time through the pressure sensor of the writing pen, it is preferable to obtain a preset number of times that the user of the writing pen is holding the pen. The touch pressure after calibration and the touch point map of the preset number of pen users after calibration of the holding posture of the pen, the maximum value and the minimum value of the touch pressure of the preset number of pen users after the calibration of the pen-holding posture are respectively set as presets The maximum and minimum values of the pressure range, and the preset number of touch point maps of the user who hold the pen after calibration are stored in the preset touch point gallery, so as to accurately obtain the current touch point map when the user of the writing pen holds the pen correctly. similarity threshold.

In step S204, when the touch area is within the preset area range, a current touch point map formed by the touch points is acquired through the touch sensor.

In the embodiment of the present invention, when a writing pen user holds the pen correctly, there are generally four contact points with the writing pen, one contact point on each of the middle finger and thumb, and two contact points on the index finger, and these four contact points are The relative position of the points on the pen holder will not change significantly. Therefore, when the touch pressure of the touch point is within the preset pressure range, the current touch point map formed by the touch point is obtained through the touch sensor. These 4 points are on the pen holder. The formed graph is the current touch point map of the writing pen user, and the current touch point map is used to determine whether the pen user's holding posture is wrong, thereby increasing the accuracy of the writing pen user's grasping posture judgment, wherein, the figure is A three-dimensional view of 4 points on the surface of the cylinder (pen holder).

In step S205, the similarity of the current touch point map is obtained by matching the current touch point map with each touch point map in the user's preset touch point gallery.

In this embodiment of the present invention, since there is more than one correct pen-holding posture, there may be multiple touch point maps formed by the correct pen-holding posture, and the specific number is determined by the personal habits of the writing pen user. After calibrating the correct pen-holding posture, the correct pen-holding posture of multiple children can be recorded in advance, so that the accuracy of identifying the correct pen-holding posture can be improved. Specifically, the current touch point map is matched with each touch point map in the user's preset touch point gallery, and after matching the similarity between the current touch point map and each touch point map is obtained, the maximum value of all the similarities is set as The similarity of the current touch point graph. For example, when the child writes by grasping the pen, the contact points are connected together and cannot form a four-point graph, which is not similar to the respective touch point graphs in the preset touch point gallery.

In order to obtain the similarity of the current touch point map more accurately, before acquiring the touch pressure of the touch point when the user of the writing pen is holding the pen in real time through the pressure sensor of the writing pen, it is further preferable to obtain a preset number of pieces of the writing pen user in the holding posture For the calibrated touch point map, a preset number of touch point maps of the writing pen user after calibration of holding the pen are stored in the preset touch point library, so as to improve the accuracy of the calculation of the similarity of the current touch point map, thereby improving the accuracy of the current touch point map. The accuracy of judgment of wrong pen-holding posture.

In step S206, when the similarity is lower than the preset similarity threshold, remind the writing pen user of the gesture of holding the pen.

In the embodiment of the present invention, when the similarity of the current touch point map is lower than the preset similarity threshold, it indicates that the writing pen user does not use the correct pen-holding posture to write. At this time, the writing user is reminded that the pen-holding posture is wrong or guide The user uses the correct pen-holding posture. For example, a vibrator in the writing pen can alert the writing pen user to the wrong posture of holding the pen. When the similarity is lower than the preset similarity threshold, preferably, the information about the wrong gesture of the user of the writing pen is obtained by matching the current touch point map with each touch point map in the preset touch point gallery, and the information on the wrong gesture of the user of the writing pen is obtained through the matching of the current touch point map and each touch point map in the preset touch point gallery. The speaker informs the writing pen user of the information and the method for correcting the pen-holding posture corresponding to the information, thereby guiding the writing-pen user to correct the wrong pen-holding posture in time, and further improving the intelligence of the writing pen.

In the embodiment of the present invention, first set the touch area range and touch pressure range when the user of the writing pen holds the pen correctly, and store the map of each touch point when the user of the writing pen correctly holds the pen, and obtain the real-time acquisition of the user of the writing pen through the pressure sensor of the writing pen The touch pressure of the touch point when holding the pen, compare the touch pressure of the touch point with the preset pressure range, when the touch pressure of the touch point is within the preset pressure range, obtain the touch area of the touch point through the touch sensor of the writing pen, Compare the touch area with the preset area range. When the touch area is not within the preset area range, remind the user of the pen holding posture. When the touch area is within the preset area range, obtain the touch point through the touch sensor. The current touch point map is formed, and the similarity of the current touch point map is obtained. When the similarity is lower than the preset similarity threshold, the pen user is reminded of the gesture of holding the pen, so as to realize the correction of the wrong gesture of the pen user. The automatic reminder enables the user of the writing pen to correct the posture of holding the pen in time, thereby improving the intelligence of the writing pen.
