Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The following detailed description of specific implementations of the present invention is provided in conjunction with specific embodiments:
the first embodiment is as follows:
fig. 1 shows an implementation flow of a pen-holding gesture reminding method for a writing pen according to an embodiment of the present invention, and for convenience of description, only the relevant parts of the embodiment of the present invention are shown, which is detailed as follows:
in step S101, the touch pressure of the touch point when the user holds the pen is obtained in real time through the pressure sensor of the pen, and the touch pressure of the touch point is compared with the preset pressure range.
The embodiment of the invention is suitable for the intelligent writing pen, and the writing pen is provided with the pressure sensor and the touch sensor. In the embodiment of the invention, the preset pressure range is a pre-acquired touch pressure range value of a writing pen user in writing under the condition of correct pen holding posture, and because the pressure (touch pressure) of the contact point of the hand of the writing pen user and the writing pen is smaller when the writing pen user only holds the writing pen on the hand (without writing), and the touch pressure is obviously increased when the writing pen user writes, the touch pressure of the touch point of the writing pen user in holding the pen is acquired in real time through the pressure sensor of the writing pen, 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 started only when it is detected that the user of the writing pen is about to use the writing pen to write, so as to obtain the touch pressure of the touch point when the user of the writing pen holds the pen in real time, thereby improving the battery service life of the writing pen. When detecting whether a writing pen user is going to use the writing pen to write, preferably, the gravity sensor of the writing pen is used to determine whether the writing pen user is going to use the writing pen to write, thereby improving the accuracy of determining the use state of the writing pen. If the writing pen is provided with the pen cap, preferably, whether the user of the writing pen is to use the writing pen for writing is judged according to whether the pen cap of the writing pen is taken down, so that the detection process of the use state of the writing pen is simplified. If the pen core of the writing pen is a telescopic pen core, preferably, whether a user of the writing pen wants to use the writing pen for writing or not is judged according to the telescopic condition of the pen core of the writing pen, so that the detection process of the using state of the writing pen is simplified.
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 obtained through the touch sensor of the writing pen, and the touch area is compared with the preset area range.
In the embodiment of the invention, the preset area range is a range value of the touch area of the touch point of the writing pen user in the correct pen holding posture, the touch pressure of the touch point is in the preset pressure range, which indicates that the writing pen user is writing with the writing pen at the moment, otherwise, indicates that the user only holds the writing pen on hand and does not write. When a writing pen user is writing with the writing pen at this time, considering that a child who has learned to write first holds the pen with the whole palm in a commonly used wrong pen holding posture, which results in a large touch area of a touch point, the touch area of the touch point is obtained through a touch sensor of the writing pen, and then the touch area is compared with a preset area range.
In step S103, when the touch area is not within the preset area range, a pen holding gesture prompt is performed for the pen user.
In the embodiment of the invention, when the touch area is not in the preset area range, the fact that the writing pen user does not use the correct pen holding posture for writing is indicated, and at the moment, the pen holding posture is reminded for the writing pen user. Specifically, the pen-holding gesture error can be reminded to the pen user through a vibrator in the pen.
In order to more accurately detect the wrong pen holding posture of the pen user, before the pressure sensor of the pen is used for acquiring the touch pressure of the touch point when the pen user holds the pen in real time, preferably, the touch pressure and the touch area of the pen users of the preset number after the pen holding posture calibration are acquired, the maximum value and the minimum value of the touch pressure of the pen users of the preset number after the pen holding posture calibration are respectively set as the maximum value and the minimum value of the preset pressure range, and the maximum value and the minimum value of the touch area of the pen users of the preset number after the pen holding posture calibration are respectively set as the maximum value and the minimum value of the preset area range, so that the range values of the touch pressure and the touch area when the pen user correctly holds the pen are accurately acquired.
In the embodiment of the invention, the touch pressure of the touch point of the writing pen user when holding the pen is obtained in real time through the pressure sensor of the writing pen, the touch pressure of the touch point is compared with the preset pressure range, when the touch pressure of the touch point is in the preset pressure range, the touch area of the touch point is obtained through the touch sensor of the writing pen, the touch area is compared with the preset area range, and when the touch area is not in the preset area range, the pen holding posture of the writing pen user is reminded, so that the intellectualization of the writing pen is realized, and the pen holding posture can be corrected in time through the automatic reminding of the writing pen.
Example two:
fig. 2 shows an implementation flow of a pen-holding gesture reminding method for a writing pen according to a second embodiment of the present invention, and for convenience of description, only the relevant parts of the embodiment of the present invention are shown, which is detailed as follows:
in step S201, the touch pressure of the touch point when the user holds the pen is obtained in real time through the pressure sensor of the pen, and the touch pressure of the touch point is compared with the preset pressure range.
The embodiment of the invention is suitable for the intelligent writing pen, and the writing pen is provided with the pressure sensor and the touch sensor. In the embodiment of the invention, because the pressure (touch pressure) of the contact point between the hand of the writing pen user and the writing pen is smaller when the writing pen user only holds the writing pen (does not write), and the touch pressure is obviously increased when the writing pen user writes, the touch pressure of the touch point when the writing pen user holds the writing pen is firstly obtained in real time through the pressure sensor of the writing pen, and then the touch pressure of the touch point is compared with the preset pressure range. Specifically, when the cap of the writing pen is removed, it may be determined that the writing pen user is ready to use the writing pen, and if the pen core of the writing pen is a retractable type pen core, it may be determined whether the writing pen user is ready to use the writing pen according to the retractable condition of the pen core of the writing pen.
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 obtained through the touch sensor of the writing pen, and the touch area is compared with the preset area range.
In the embodiment of the invention, the preset area range is a range value of the touch area of the touch point of the writing pen user in the correct pen holding posture, the touch pressure of the touch point is in the preset pressure range, which indicates that the writing pen user is writing with the writing pen at the moment, otherwise, indicates that the user only holds the writing pen on hand and does not write. When a writing pen user writes by using the writing pen at the moment, considering that a child who learns to write for the first time holds the pen by the whole palm in a commonly used wrong pen holding posture, the touch area of a touch point is large, and therefore the touch area of the touch point is obtained by a touch sensor of the writing pen firstly, and then the touch area is compared with a preset area range.
In step S203, when the touch area is not within the preset area range, a pen holding gesture prompt is performed for the pen user.
In the embodiment of the invention, when the touch area is not in the preset area range, the fact that the writing pen user does not use the correct pen holding posture for writing is indicated, and at the moment, the pen holding posture is reminded for the writing pen user. Specifically, the pen-holding gesture error can be reminded to the pen user through a vibrator in the pen.
In order to more accurately detect the wrong pen holding posture of the writing pen user, before the touch pressure of the touch point of the writing pen user when the writing pen user holds the pen is acquired in real time through a pressure sensor of the writing pen, preferably, the touch pressure of a preset number of times of writing pen users after pen holding posture calibration and the touch point diagram of a preset number of times of writing pen users after pen holding posture calibration are acquired, the maximum value and the minimum value of the touch pressure of the preset number of times of writing pen users after pen holding posture calibration are respectively set as the maximum value and the minimum value of a preset pressure range, the touch point diagram of the preset number of times of writing pen users after pen holding posture calibration is stored in a preset touch point diagram library, and therefore the similarity threshold value of the current touch point diagram of the writing pen user when the writing pen user correctly holds the pen is accurately acquired.
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 invention, when a writing pen user holds a pen correctly, the number of contact points between the writing pen user and the writing pen is generally 4, each of the middle finger and the thumb has one contact point, the index finger has two contact points, and the relative positions of the 4 points distributed on the pen container do not change obviously, so that when the touch pressure of the touch points is within a preset pressure range, a current touch point diagram formed by the touch points is obtained through a touch sensor, a graph formed by the 4 points on the pen container is the current touch point diagram of the writing pen user, and whether the pen holding posture of the writing pen user is wrong or not is judged through the current touch point diagram, so that the accuracy of judging the pen holding posture of the writing pen user is increased, wherein the graph is a three-dimensional graph formed by the 4 points on the surface of a cylinder (pen container).
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 preset touch point map library of the user.
In the embodiment of the invention, as more than one correct pen holding posture is adopted, a plurality of touch point diagrams formed by the correct pen holding posture can be formed, and the specific number is determined by the personal habits of the pen writing users, so that the correct pen holding postures of a plurality of children can be input in advance after the parents and teachers calibrate the pen holding postures of the children, and the accuracy rate of identifying the correct pen holding posture can be improved. Specifically, matching is performed on the current touch point diagram and each touch point diagram in a preset touch point diagram library of the user, and after the similarity between the current touch point diagram and each touch point diagram is obtained through matching, the maximum value of all the similarities is set as the similarity of the current touch point diagram. For example, when a child writes by holding a pen with the palm, the contact points are connected to form a graph of 4 points, which is not similar to each touch point graph in the preset touch point graph library.
In order to more accurately acquire the similarity of the current touch point diagram, before the pressure sensor of the writing pen is used for acquiring the touch pressure of the touch point when the writing pen user holds the pen in real time, it is further preferable to acquire the touch point diagrams of a preset number of writing pen users after the pen holding gesture calibration, and store the touch point diagrams of the preset number of writing pen users after the pen holding gesture calibration in a preset touch point diagram library, so that the accuracy of calculating the similarity of the current touch point diagram is improved, and the accuracy of judging the wrong pen holding gesture is improved.
In step S206, when the similarity is lower than the preset similarity threshold, a pen-holding gesture prompt is performed for the pen user.
In the embodiment of the invention, when the similarity of the current touch point diagram is lower than the preset similarity threshold, the fact that the writing pen user does not use the correct pen holding posture for writing is indicated, and at the moment, the writing user is reminded of the error of the pen holding posture or is guided to use the correct pen holding posture. For example, a stylus user may be alerted of a pen-holding gesture error by a vibrator in the stylus. When the similarity is lower than the preset similarity threshold, preferably, the information of the wrong pen holding posture of the writing pen user is obtained through matching of the current touch point diagram and each touch point diagram in the preset touch point diagram library, and the writing pen user is informed of the information and a method for correcting the pen holding posture corresponding to the information through a loudspeaker in the writing pen, so that the writing pen user is guided to correct the wrong pen holding posture in time, and the intelligent degree of the writing pen is further improved.
In the embodiment of the invention, a touch area range and a touch pressure range when a writing pen user holds a pen correctly are set, and each touch point diagram when the writing pen user holds the pen correctly is stored, the touch pressure of a touch point when the writing pen user holds the pen is obtained in real time through a pressure sensor of the writing pen, the touch pressure of the touch point is compared with a preset pressure range, when the touch pressure of the touch point is in the preset pressure range, the touch area of the touch point is obtained through the touch sensor of the writing pen, the touch area is compared with the preset area range, when the touch area is not in the preset area range, the pen holding posture of the writing pen user is reminded, when the touch area is in the preset area range, a current touch point diagram formed by the touch point is obtained through the touch sensor, the similarity of the current touch point diagram is obtained, and when the similarity is lower than a preset similarity threshold value, the pen holding posture of the writing pen user is reminded, so that the pen holding posture of the writing pen user is automatically reminded of the wrong pen holding posture, the writing pen user can correct the pen holding posture in time, and the intelligent degree of the writing pen is improved.
