Description

Technical Field

[0001] The present invention relates to the field of intelligent pen writing, and particularly to a device, method, equipment and storage medium for automatically erasing handwriting. Background Art

[0002] In the field of intelligent pen writing, a dot matrix pen needs to be combined with a dot code carrier to be used. The dot matrix pen can generate handwriting on the dot code carrier and convert the dot codes on the dot code carrier into digital objects after collecting them. The dot code carrier can be an ordinary piece of paper paved with (for example, printed with) dot codes. For the existing handwriting written by a dot matrix pen (such as pencil handwriting), after being erased on the dot code carrier, the corresponding digital object inside the dot matrix pen will not be erased synchronously. If a writing error occurs and it is necessary to erase the digital object in the dot matrix pen at the same time, it is necessary to manually erase the digital object inside the dot matrix pen by pressing a button on the dot matrix pen or in cooperation with other devices. The erasing operation is too complex and very inconvenient, and the cost of setting up a button or other devices for synchronous erasing is also relatively high. Summary of the Invention

In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non - exclusive inclusion.

[0052] Please refer to both Figure 1 and Figure 2, this embodiment provides a handwriting automatic erasing device 10a, which includes a writing unit 100, a collection unit 101, and a processor 102. The handwriting automatic erasing device 10a is used in conjunction with the dot code carrier 2. The dot code carrier 2 can be an ordinary piece of paper paved with (for example, printed with) dot codes. The handwriting automatic erasing device 10a can be a dot matrix pen with a writing unit 100, a collection unit 101, and a processor 102. The writing unit 100 is used to generate a first handwriting 5 and a second handwriting 6. For example, the writing unit 100 can be the refill of a pencil, a gel pen, a ballpoint pen, or other pens. When the dot code carrier 2 is an ordinary piece of paper, the writing unit 100 can directly write on the dot code carrier 2. The collection unit 101 is directly or indirectly connected to the writing unit 100. For example, the collection unit 101 and the writing unit 100 can be connected through the pen shaft. The collection unit 101 can be a camera. The collection unit 101 is used to collect the dot codes passed by the handwriting on the dot code carrier 2, that is, to collect the dot codes passed by the first handwriting 5 and the second handwriting 6 when the writing unit 100 writes on the dot code carrier 2, and convert the dot codes passed by the first handwriting 5 into a first digital object, and convert the dot codes passed by the second handwriting 6 into a second digital object. The processor 102 is electrically connected to the collection unit 101. The processor 102 is used to receive the first digital object and convert the first digital object into the coordinates of the first handwriting 5. The processor 102 is used to receive the second digital object and convert the second digital object into the coordinates of the second handwriting 6. The processor 102 can further convert the coordinates of the first handwriting 5 into the digital features of the first handwriting 5 for output, and convert the coordinates of the second handwriting 6 into the digital features of the second handwriting 6 for output. For example, it can be displayed on a display. The handwriting automatic erasing device 10a can be connected to a mobile terminal 7 (such as a mobile phone, a tablet) in a wired or wireless manner, so as to output the digital features of the first handwriting 5 and the digital features of the second handwriting 6 to the mobile terminal 7 for display. The user can see that the shape of the digital features of the first handwriting 5 on the mobile terminal 7 is the same as the shape of the first handwriting 5 on the dot code carrier 2, and the shape of the digital features of the second handwriting 6 seen on the mobile terminal 7 is the same as the shape of the second handwriting 6 on the dot code carrier 2. When automatic erasing of handwriting is required, the processor performs the following operations.

[0053] Please refer to Figure 1 and Figure 2 , this embodiment provides a method for automatic erasing of handwriting, which is processed and executed by the processor 102 on the handwriting automatic erasing device 10a. After the dot codes 3 passed by the handwriting on the dot code carrier 2 are collected by the collection unit 101, they are converted into a digital image, and after the digital image is received by the processor 102, it is converted into digital coordinates. Please also refer to Figure 2 , Figure 3 and Figure 5, the handwriting automatic erasure method includes the following steps. Step S1: Send a connection instruction to establish a connection between the handwriting automatic erasure device 10a and the mobile terminal 7. Establishing a connection between the handwriting automatic erasure device 10a and the mobile terminal 7 can send the digital features of the handwriting generated by the handwriting automatic erasure device 10a to the mobile terminal 7 for output. For example, the digital features of the handwriting are displayed on the APP of the mobile terminal 7. The handwriting automatic erasure device 10a and the mobile terminal 7 can be connected by wired or wireless means, such as through Wi-Fi. Step S2: Set the coordinate range. Step S3: Receive the coordinates of the first handwriting 5, where the coordinates of the first handwriting 5 are within the coordinate range. Step S4: Send a first display instruction to display the digital features of the first handwriting 5 on the mobile terminal 7. If no second handwriting 6 is generated within the coordinate range, only the digital features of the first handwriting 5 will be displayed on the mobile terminal 7. Step S5: Receive the coordinates of the second handwriting 6. Step S6: Determine whether the coordinates of the second handwriting 6 are within the coordinate range. If so, execute Step S7. If not, execute Step S5. Step S7: Overwrite the coordinates of the first handwriting 5 with the coordinates of the second handwriting 6. Usually, only one character is written within the same coordinate range. If a second character appears again, it is very likely that the user erased the original character and rewrote a character within the range. Therefore, by judging the coordinate range where the handwriting falls, it can be inferred whether the user erased the originally written character. Then comes Step S8: Send a second display instruction to display the digital features of the second handwriting 6 on the mobile terminal 7. After the connection between the handwriting automatic erasure device 10a and the mobile terminal 7 is established, sending a second display instruction to display the digital features of the second handwriting 6 on the mobile terminal 7 can allow the user to clearly see only the digital features of the second handwriting 6. Therefore, the present invention enables the user to use the smart pen more intuitively. For example, the user first generates a first handwriting 5 within the code point range 4 (for example, the writing unit 100 is a handwriting automatic erasure device of a pencil and writes the number "1" on the dot code paper), discovers that it is wrong and erases it (for example, erases the pencil handwriting with an eraser, that is, the pencil handwriting of the number "1"), and then generates a second handwriting 6 (for example, the number "2") at the original writing position on the dot code carrier 2. According to this embodiment, the coordinates of the first handwriting 5 generated first in the automatic erasure device 10a will be overwritten by the coordinates of the second handwriting 6 generated later. After the coordinates of the second handwriting 6 generated later are converted into digital features by the processor 102, they will be sent to the mobile terminal 7 for output, such as being displayed on the APP of the mobile terminal 7 (that is, displaying the number "2"). Therefore, the user can write more intuitively.

[0054] For example, in a teaching scenario, the mobile terminal 7 is set at the teacher's place. After the teacher assigns an exercise, such as a multiple-choice question, the student uses a writing unit 100 (such as a pencil) on the handwriting automatic erasing device 10a to answer within the coordinate range 4 on the dot code carrier 2 (such as a notebook printed with dot codes 3). If the answer written by the student within the coordinate range 4 is A at first, and then the student finds that the answer is wrong and erases the answer A within the coordinate range 4 with an eraser and rewrites the answer B within the coordinate range 4, after executing the note automatic erasing method, the answer seen on the mobile terminal 7 at the teacher's end will be B.

[0055] By setting a coordinate range within the handwriting automatic erasing device 10a, after the coordinates of the first handwriting 5 are received and fall within the set coordinate range, if it is determined that the second handwriting 6 also falls within the set coordinate range, the coordinates of the first handwriting 5 are automatically overwritten with the coordinates of the second handwriting 6, and there is no need to set a button or rely on other devices to delete the coordinates of the first handwriting 5, saving the steps required for handwriting erasure, improving the efficiency of handwriting erasure of the handwriting automatic erasing device 10a, and reducing the cost of erasing handwriting.

[0056] For example, please also refer to Figure 1 、 Figure 2 、 Figures 5 to 8 , the dot code carrier 2 is a piece of paper, and the dot codes 3 are laid (such as printed) on the paper. A dot code range 4 is preset (or predefined) on the dot code carrier 2, and the coordinate range corresponding to the dot codes 3 falling within the dot code range 4 can be preset by the processor 102. The writing unit 100 of the handwriting automatic erasing device 10a is a pencil, and the first handwriting 5 written is the number "1". After the first handwriting 5 is generated within the dot code range 4, the mobile terminal 7 will display the number "1" according to the digital features generated by the handwriting automatic erasing device 10a. If the user finds that the answer is wrong and wants to erase the number, at this time, it is necessary to erase the first handwriting 5 on the dot code carrier 2 (that is, erase the first handwriting 5 written with a pencil), for example, it can be erased with an eraser. Although the first handwriting 5 on the paper has been erased with an eraser (such as Figure 7As shown, but since the code point 3 of the first handwriting 5 has been collected into the handwriting automatic erasure device 10a and converted into coordinates, the coordinates of the first handwriting 5 in the handwriting automatic erasure device 10a are still retained at this time, that is, the mobile terminal 7 still displays the digitalized features of the originally retained number "1". According to the present invention, after the first handwriting 5 is erased on the dot code carrier 2, if a second handwriting 6 (such as the number "2") is written with a pencil within the code point range 4 on the dot code carrier 2, after the code points passed by the second handwriting 6 are collected and converted into coordinates, the processor 102 can determine whether the corresponding coordinates of the second handwriting 6 are within the coordinate range. If so, at this time, the handwriting automatic erasure device 10a covers the coordinates of the first handwriting 5 with the coordinates corresponding to the second handwriting 6. If the digitalized features generated by the handwriting automatic erasure device 10a are output at this time, for example, displayed on the screen (such as output to the mobile terminal 7 for display), then the digitalized features of the second handwriting 6 (i.e., the number "2") are seen on the screen. The handwriting automatic erasure method can more intuitively see the erasure effect of the written first handwriting 5, that is, when the first handwriting 5 on the dot code carrier 2 is erased, the coordinates of the first handwriting 5 in the handwriting automatic erasure device 10a are also deleted at the same time, that is, the mobile terminal 7 displays the digitalized features of the handwriting of the "2" (the second handwriting 6) rewritten after the erasure of the first handwriting 5.

[0057] As Figure 4 shown, preferably, step S3 includes step S30 and step S31. Step S30 includes: recording the residence time of the current coordinates of the first handwriting 5. Step S31 includes: determining whether the residence time of the current coordinates of the first handwriting 5 is greater than a predetermined time interval. If so, execute step S5. If not, execute step S30. After recording the residence time of the current coordinates of the first handwriting 5, it is possible to determine whether the first handwriting 5 has been generated by the residence time of the current coordinates of the first handwriting 5, so as to be able to automatically distinguish whether the current handwriting is the first handwriting 5 or the second handwriting 6. Preferably, the time interval is 3 seconds.

[0058] For example, when the user writes the Chinese character "知" (knowledge) within the selected code point range 4, the radical "矢" (arrow) will be generated first. If the residence time of the current coordinates of the radical "矢" (arrow) is less than the predetermined time interval, the coordinates of the radical "矢" (arrow) will continue to be received as the first handwriting 5. If the radical "矢" (arrow) has been written, and the residence time of the current coordinates of the handwriting after the radical "矢" (arrow) is still less than the predetermined time interval, the current coordinates of the subsequent handwriting will also be received as the first handwriting 5. After the writing of the radical "矢" (arrow) is completed and before the writing of the radical "口" (mouth) is completed, if the residence time of the current coordinates of the radical "口" (mouth) is still less than the predetermined time interval until the residence time of the current coordinates of the radical "口" (e.g., the last coordinate of the radical "口") is greater than the predetermined time interval, the entire Chinese character "知" (knowledge) will be received as the first handwriting 5, and the first handwriting 5 received is "知". If the coordinates of the radical "矢" have been generated, and the residence time of its current coordinates (for example, the last coordinates of the radical "矢") is greater than the predetermined time interval, the radical "矢" will be received as the first handwriting 5, and the coordinates after "矢" will be received as the second handwriting 6. Since the second handwriting 6 is also within the coordinate range, the subsequent step S7 will be executed after the judgment of step S6, that is, the radical "矢" will be covered, and the coordinates after "矢" (for example, the coordinates of the complete "口") will be retained. At this time, if the digital features of the coordinate conversion of the handwriting are displayed, "矢" will not be displayed, and the coordinates after "矢" (for example, the digital features of the coordinate conversion of the complete "口") will be displayed. Therefore, when the user writes within the code point range 4, if the residence time after writing a word exceeds the predetermined time interval (for example, more than 3 seconds), the handwriting automatic erasing device 10a will determine that the handwriting has been completed, and then execute the subsequent steps.

[0059] Please also refer to Figure 8 and Figure 9, this embodiment provides a handwriting automatic erasing device 10b, including: a connection instruction sending unit 103, a coordinate setting unit 104, a first coordinate receiving unit 105, a first display instruction sending unit 106, a second coordinate receiving unit 107, a coordinate judging unit 108, a coordinate covering unit 109, and a second display instruction sending unit 110. The connection instruction sending unit 103 is connected to the coordinate setting unit 104, and the connection instruction sending unit 103 is used to send a connection instruction to establish a connection between the handwriting automatic erasing device 10a and the mobile terminal 7.

The second display instruction sending unit 110 is connected to the coordinate covering unit 109, and the second display instruction sending unit 110 is used to send a second display instruction to display the digital features of the second handwriting 6 on the mobile terminal 7. By setting the coordinate setting unit 104, the first coordinate receiving unit 105, the second coordinate receiving unit 107, the coordinate judging unit 108, and the coordinate covering unit 109. Using the coordinate setting unit 104 to set the coordinate range, after the coordinates of the first handwriting 5 are received and fall within the set coordinate range, if the coordinate judging unit 108 judges that there is also a second handwriting 6 that falls within the set coordinate range, the coordinate covering unit 109 automatically covers the coordinates of the first handwriting 5 with the coordinates of the second handwriting 6, and there is no need to set a button or rely on other devices to cover the coordinates of the first handwriting 5, saving the steps required for handwriting erasure, improving the erasure efficiency, and reducing the erasure cost.

The time recording unit 1050 is connected to the coordinate setting unit 104 and the time judgment unit 1051. The time recording unit 1050 is used to record the residence time of the current coordinate of the first handwriting 5. The time judgment unit 1051 is connected to the second coordinate receiving unit 107.
