The first switching identifier 602 may be a switching button of a previous poem, the second switching identifier 603 may be a switching button of a next poem, and the user may switch the poem displayed on the third interface 601, that is, switch the reference content, by triggering the first switching identifier 602 or the second switching identifier 603. The matching identifier 604 is a switch for performing transcription comparison and judgment, and in a normal case, the default matching identifier 604 is in a closed state, and after the user triggers the matching identifier 604, that is, after the transcription comparison and judgment switch is opened, the judgment logic of the judgment module can be used for comparing the reference poetry and the writing poetry. The display condition that the second interface is dragged on the first interface is shown as a first interface 620, the position of the second interface 610 before the second interface 610 is not dragged in the first interface 620 is recorded as a first position, the second interface 610 is dragged from the first position to a second position in the first interface 610 according to the arrow direction, and the writable area in the first interface 620 is changed according to the second position of the second interface 610 in the first interface 620.

In some embodiments, in the case that the reference content is a poem, the reference content is mostly composed of three parts of a title, an author and a text, the text part is composed of a text and punctuation marks, the text part uses the punctuation marks as separators, and the text part is split into a plurality of comparison units, wherein the punctuation marks of the text part are only used as separators and do not participate in matching. Sequentially numbering the title, the author and the text part except for the punctuation mark, dividing the title, the author and the text part except for the punctuation mark into a plurality of comparison units, and removing the comparison units which are already involved in the matching according to the matching rule of the reference content, wherein the punctuation mark is only used as a separator and does not participate in the matching process. The identified handwritten content may include characters and punctuations, or may include characters, and is not limited to the format of the handwritten content.

For example, referring to fig. 9, fig. 9 is a diagram showing that the reference content includes a title, an author, and a text portion, which are sequentially split into 6 comparison units numbered C0 to C5, etc., the title is denoted as comparison unit C0, the author is denoted as comparison unit C1, and the text portion is denoted as comparison units C2 to C5.

In some embodiments, fig. 10 shows a step flowchart of a method for displaying the handwriting content in some embodiments, and as shown in fig. 10, the method for displaying the handwriting content specifically includes the following steps S110 to S150:

taking fig. 9 as an example of the second comparison information S2, the following embodiment will be described in detail.

Wherein, a final matching result of the complete matching of the first comparison information S1 and the second comparison information S2 can be obtained according to S110 to S150.

S110, a first pointer points to a first character in the at least one first character, and a second pointer points to a first second character in the at least one second character.

And S120, matching the first character with the first second character to obtain a first matching result of the first character.

And S130, if the first matching result is that the first character is identical to the first character, respectively moving the first pointer and the second pointer backwards by one bit to point to a second first character and a second character.

And S140, matching the second first character with the second character to obtain a second matching result of the second first character.

And S150, if the second first character is the same as the second character and the second first character is the last first character in the at least one first character, generating a final matching result of the writing content and the reference content according to the first matching result and the second matching result.

If the transcription sequence, the word number and the content of the writing content and the reference content are completely matched, the second character related in the reference content and correctly matched is marked as green, or the background color of the second character is marked as green, and the marking mode of the second character correctly matched is not limited and can be set according to the user requirement.

The written content of the user is identified and stored as a character string, which is denoted as first comparison information S1, and the reference content file is stored as a character string, which is denoted as second comparison information S2. The first pointer and the second pointer are respectively pointed to the first characters of S1 and S2, the first pointer is marked as a pointer i, the second pointer is marked as a pointer j, the first pointer points to the first character (the first character) in the first comparison information, the second pointer points to the first second character (the first second character) in the second comparison information, the first character pointed by the pointer i and the pointer j and the first second character are compared to obtain a first matching result, if the first matching result is the same (i.e. the comparison result is equal to) of the first character and the first second character, the pointer i and the pointer j are moved backwards by one bit at the same time, the second character pointed by the new pointer is compared again, and so on until the pointer i points to the last first character of S1, wherein the matching result obtained each time is equal to the comparison result, and a final matching result with completely matched handwriting content is generated according to the matching result of each first character.

For example, referring to FIG. 11, FIG. 11 shows a schematic diagram of a perfect match in some embodiments, as shown in FIG. 11, pointer i points to the first character "bed" of S1, pointer j points to the first second character "bed" of S2, and the results of the match of the first character "bed" and the first second character "bed" are the same. And simultaneously shifting the pointer i and the pointer j backwards by one bit, and the like until the pointer i points to the last first character light of the S1, the pointer j points to the last second character light of the first comparison unit of the S2, and the matching result of each character is the same, so that a final matching result of complete matching of the comparison units (marked as first comparison units) with the number C2 in the S1 and the S2 is generated, and the first comparison units in the S2 are marked as green. The matching process of the acquired next writing content and the comparing unit (second comparing unit) with the number C3 in S2 shown in fig. 11 is the same as that of the previous writing content, and is not described herein, and the second comparing unit in S2 is marked green, and the correct character marked green in fig. 11 is light gray.

In some embodiments, the first comparison information S1 and the second comparison information S2 are matched to obtain a final matching result of the first missing word of the written content, which is specifically implemented by the following steps:

The final matching result of the word missing of the sentence head of the writing content is particularly transcription sequence matching, but the word missing exists in the writing content, the second character of the sentence head in the reference content is marked red in the sentence head, and the second character on the later matching is marked green.

For example, referring to fig. 12, fig. 12 shows a schematic diagram of a period with a missing word in some embodiments, if the first matching result is that the first character and the first second character are different, that is, the pointer i and the pointer j point to the first character of the character strings S1 and S2 respectively, and the two first characters are not equal, as shown in fig. 1201, the pointer i points to the first character "front" of S1, the pointer j points to the first second character "bed" of S2, the matching result of the first character "front" and the first second character "bed" is different, four first characters are calculated to be included in S1, the first characters can be understood as valid characters, the first comparing unit in S2 includes five second characters, and the second characters are also valid characters, so that the writing content is primarily determined to be a missing word. Then, the first pointer is fixed, the second pointer is moved backwards by one bit to point to the second character, the first character and the second character are matched to obtain a third matching result of the first character, if the third matching result is that the first character and the second character are identical, the first pointer and the second pointer are respectively moved backwards by one bit to point to the second first character and the third second character, as shown in a diagram 1202, the pointer i is kept fixed, the pointer j is moved backwards by one bit, at the moment, the characters pointed by the pointer i and the pointer j are identical, the pointer i and the pointer j are moved backwards simultaneously, the remaining characters are continuously matched, and the subsequent second first character and the third second character, the third first character and the fourth second character are completely matched. As shown in diagram 1203, pointer i points to the last first character "light" of S1, and the last four characters of S1 and S2 are completely matched to generate a final matching result of the initial characters of the written content, which is specifically understood as sequential matching, but in a comparison unit, there is a condition of the initial characters, and the comparison result is displayed at the same time, that is, after the matching is finished, the character with correct matching is marked as green, and the character with the initial non-matching is marked as red. In the diagram 1203, the correctly matched character marked green is displayed in light gray, the unmatched character marked red is displayed in dark gray, and the specific display parameters are not limited.

The method comprises the steps of matching first comparison information S1 with second comparison information S2 to obtain a final matching result of the missing words in the written content sentence, and specifically comprises the following steps:

in some embodiments, if the second matching result is that the second first character and the second character are different, then shifting the second pointer backward by one bit to point to a third second character;

The matching result of the missing words in the written content sentence is specifically sequential matching, but in the case that the missing words in the sentence exist in one comparison unit of the S2, the second characters in the reference content and on the first character matching are marked as green, and the second characters corresponding to the missing word positions are marked as red.

For example, referring to fig. 13, fig. 13 shows a schematic diagram of a missing word in a sentence in some embodiments, where pointer i and pointer j point to the first character of S1 and S2, respectively, and the characters pointed to by pointer i and pointer j are equal, pointer i and pointer j are moved back simultaneously, and the matching of the remaining characters continues, as shown in fig. 1301, the matching results of "bed" and "front" in S1 are both regarded as first matching results, the first matching result is a perfect match, and the two second characters are marked green. In the diagram 1302, the characters pointed by the pointer i and the pointer j are not equal, at this time, the "month" pointed by the pointer i is regarded as the second first character, the "bright" pointed by the pointer j is regarded as the second character, and the second matching result is that the characters pointed by the pointer i and the pointer j are not equal, in this case, four valid characters are calculated to be included in S1, five valid characters are included in the first comparing unit in S2, and the first two characters of S1 have been completely matched with the first two characters of S2. As shown in fig. 1303, pointer i is motionless, pointer j moves one bit backward, and the "month" pointed by pointer i and the "month" pointed by pointer j are completely matched. As shown in the diagram 1304, the pointer i and the pointer j continue to move backward by one bit, and the pointer i points to the last first character, after the above judgment is obtained, a final matching result of the missing word in the written sentence is generated, that is, the situation that the missing word in the sentence is found in a comparison unit of S2, the matching is ended, the correct matching character is marked green, the second character "bright" corresponding to the missing word position in S1 is marked red, also in the diagram 1304, the green is marked light gray, and the red is marked dark gray.

The matching result of the writing content with the word missing at the end of the sentence is specifically sequential matching, but when the word missing at the end of the sentence exists in one comparison unit of the S2, the second character in the reference content and on the first character matching is marked as green, the second character corresponding to the end of the sentence of the S1 is marked as red, the word missing at the end of the sentence is the same as the word missing at the end of the sentence, and the matching process is basically the same and is not repeated herein.

For example, referring to fig. 14, fig. 14 shows a schematic diagram of an end-of-sentence word missing in some embodiments, as shown in fig. 1401, pointer i and pointer j point to the first character of S1 and S2, respectively, and the characters pointed to by i and j are equal, and pointer i and pointer j are moved back one bit at the same time, and the remaining characters continue to be matched. In diagram 1402, pointer i points to the last first character "month" of S1, pointer j points to the second last character of the first comparison unit in S2, indicating that S1 has been matched and completely matched, but that there are remaining second characters in the first comparison unit in S2 that have not been matched, marking the character that has been matched in S2 as green, and simultaneously removing the second character that has been matched in S2. In fig. 1403, the next written content transcribed by the user is acquired and saved as S1 again, pointer i points to the first character of S1, pointer j points to the last second character of the first comparison unit in S2, the two characters are unequal, in this case, pointer i remains motionless, pointer j moves one bit backward, as shown in fig. 1404, at this time pointer j points to the first second character of the second comparison unit in S2, and the characters pointed to by pointer i and pointer j are equal, the remaining characters are continuously compared, in fig. 1405, pointer i points to the last first character of S1, pointer j points to the last second character of the second comparison unit in S2, and the characters in S1 and S2 are completely matched, then it is determined that the comparison is sequential matching, but in the first comparison unit, there is a situation of a period end word missing, that is, a final matching result of a sentence end word missing in the present writing is generated, the matching is ended, the second character at the end of the first comparison unit in S2 is marked red by "light", and the second character marked in S2 is completely green.

The method comprises the steps of matching first comparison information S1 with second comparison information S2 to obtain a final matching result of the sentence head and the word of the written content, and specifically comprises the following steps:

in some embodiments, if the fifth matching result is that the second first character and the first second character are different, then shifting the second pointer backward by one bit to point to the second character;

The matching result of the sentence-head word of the written content is specifically sequence matching and word number matching, but when the sentence-head word exists in one comparison unit of S2, the second character in the reference content and on the first character matching is marked as green, and the second character (the first character with wrong writing) which is not matched is marked as red.

For example, referring to fig. 15, fig. 15 shows a schematic diagram of a sentence in some embodiments, as shown in fig. 1501, pointer i and pointer j point to the first character of S1 and S2, respectively, and the "wood" pointed to by pointer i and the "bed" pointed to by pointer j are unequal, pointer i remains unchanged, pointer j is moved back one bit, the "wood" pointed to by pointer i and the "front" pointed to by pointer j are not the same, pointer i continues to be unchanged, pointer j is moved back one bit, and so on to continue to match the remaining characters until a second character matching the "wood" pointed to by pointer i is found, or pointer j points to the last second character in S2, in which case pointer j continues to be moved back one bit, i.e., pointer j completes one round, pointer j in turn points to the first second character in S2, pointer i and pointer j are moved back simultaneously. In graph 1502, pointer i points to the first character "front" of S1 and pointer j points to the second character "front" of the first comparison unit in S2, with the two characters being equal, while pointer i and pointer j are simultaneously moved back, continuing the comparison of the remaining characters. In fig. 1503, the pointer i points to the last first character "light" of S1, the pointer j points to the last second character "light" of the first comparing unit in S2, and the characters of the last four bits in S1 and S2 are completely matched, then it is determined that the comparison sequence is matched this time, the number of words is equal, but in the case that the word with the sentence head is wrong in S1, that is, a final matching result of writing the word with the sentence head is generated, this matching is finished, the second character "bed" of the sentence head of the first comparing unit in S2 is marked red to prompt the user of the word with the sentence head, and all the remaining second characters of the first comparing unit in S2 are marked green.

In some embodiments, the first comparison information S1 and the second comparison information S2 are matched to obtain a final matching result of the miscord in the written sentence, which is specifically implemented by the following steps:

The matching result of the wrong word in the written content sentence is specifically sequential matching, and the number of words is matched, but in the case of the wrong word in the sentence in S1, the second character in the reference content and on the first character matching is marked as green, and the second character (the first character with the wrong writing in the sentence) which is not matched is marked as red.

For example, referring to fig. 16, fig. 16 shows a schematic diagram of a word-in-sentence error in some embodiments, in fig. 1601, pointer i and pointer j point to the first character of strings S1 and S2, respectively, and when the characters pointed to by pointer i and pointer j are equal, pointer i and pointer j are simultaneously shifted backward by one bit to continue matching. In graph 1602, pointer i points to "day", pointer j points to "month", the characters pointed to by the two pointers are not equal, it is calculated that five valid characters are included in S1, the first comparison unit in S2 also includes five valid characters, the number of explanatory characters is equal, and the first three characters in S1 and S2 have been completely matched, in which case pointer i remains unchanged, pointer j moves one bit backward, and so on to continue matching the remaining characters until a second character matching the "day" pointed to by pointer i is found, or pointer j points to the last second character in S2 but not equal, in which case pointer j continues to move one bit backward, i.e., pointer j completes one round while removing the first three characters that have been completely matched in S2, pointer j points to the second character "month" in S2, and pointer i and pointer j move backward simultaneously. In fig. 1603, the pointer i points to the last first character "light" of S1, and the pointer j points to the last second character "light" of the first comparing unit of S2, and the two characters are equal, so that the matching is considered to belong to transcription sequence and word number matching, but the matching is ended when there is a wrong word in the sentence, and the character with correct matching in S2 is marked green, and the character with incorrect matching is marked red.

In some embodiments, the first comparison information S1 and the second comparison information S2 are matched to obtain a final matching result of the written content sentence head multiple words, which is specifically implemented by the following steps:

if the third matching result is that the first character is different from the second character, and the second character is the last second character in the at least one second character, respectively moving the first pointer and the second pointer backwards by one bit to point to the second first character and the first second character; matching the second first character with the first second character to obtain a fifth matching result of the second first character; and if the fifth matching result is that the second first character is the same as the first second character and the second first character is the last first character, generating a final matching result of the writing content sentence head multiple words according to the first matching result, the second matching result and the fifth matching result.

The matching result of the sentence head multiple words of the writing content is specifically sequential matching, the word numbers are not matched, but in the case that the sentence head multiple words exist in S1, the second character in the reference content and on the first character matching is marked as green, and the multiple word mark is marked at the position corresponding to the sentence head multiple words in the reference content, and the multiple word mark can be a red exclamation mark so as to prompt a user to transcribe one word more in the sentence head.

For example, referring to FIG. 17, FIG. 17 shows a schematic diagram of a period multiword in some embodiments, pointer i and pointer j point to the first character of S1 and S2, respectively, pointer i points to "see", pointer j points to "bed", the two characters are not equal, pointer i remains stationary, pointer j moves backward bit by bit, and the first character of S1 is compared. In the graph 1702, until the last second character "frost" in S2 is still not equal to the "look" pointed by the pointer i, that is, after the "look" pointed by the pointer i is to be compared with all the remaining unmatched characters in S2 one by one, there is no second character equal to the first character in S1, and it is calculated that S1 contains six characters, one comparison unit in S2 contains five characters, then the pointer i and the pointer j are moved backward by one bit at the same time, that is, the pointer j completes one round, at this time, the pointer i points to "bed", the two characters are equal, then the pointer i and the pointer j are moved backward at the same time until the pointer i points to the last first character "light" in S1, the pointer j points to the last second character "light" in the first comparison unit in S2, so that this time matching is determined to be sequential matching, but in one comparison unit in S2, there is a case of multiple words in the first comparison unit in S1, the first word is marked before the first character in the comparison unit in S2.

The matching result of the multiple words in the written content sentence is specifically sequential matching, the number of words is not matched, but in the case of multiple words in the sentence in S1, the second character in the reference content and on the first character matching is marked green, and the multiple word mark is marked at the multiple word position in the reference content, and the multiple word mark can be a red exclamation mark so as to prompt the user to transcribe one more word in the sentence.

For example, referring to FIG. 18, FIG. 18 shows a schematic diagram of multiple words in a sentence in some embodiments, in FIG. 1801, pointer i and pointer j point to the first character of S1 and S2, respectively, and the two characters are equal, then pointer i and pointer j are moved back simultaneously to continue comparing the following characters. In the graph 1802, the pointer i points to "see", the pointer j points to "bright", the characters pointed to by the pointer i and the pointer j are unequal, the pointer i remains motionless, the pointer j moves backward bit by bit and is compared with the first character of S1 until the last second character "frost" in S2 is compared, that is, after the "see" pointed to by the pointer i is compared with all the remaining unmatched characters in S2, the second character is not equal to the first character of S1, and the number of characters is unequal, one comparing unit of S2 contains five characters. In fig. 1803, pointer i and pointer j are moved back one bit at the same time, that is, pointer j completes one round, at this time, pointer i points to "bright", after deleting the first 2 bits in S2, pointer j points to "bright", two characters are equal, pointer i and pointer j are moved back at the same time until pointer i points to the last first character "light" of S1, pointer j points to the last second character "light" of the first comparison unit in S2, two characters are equal, it is determined that the present match belongs to sequential match, but in one comparison unit, there is a case of multiple words in a sentence, a red exclamation mark is displayed between "bright" and "front" in a sentence, the user is prompted to transcribe multiple words in S2, the present match is ended, the character matched by the first comparison unit in S2 is marked green, and multiple word identifiers are marked between "bright" and "front".

If the written content may have a final matching result that is not transcribed in sequence, that is, the poetry is not transcribed in the sequence of the S2 numbers, the part skipped in S2 is marked red, and the matching part is marked green.

For example, referring to FIG. 19, FIG. 19 shows a schematic diagram of a sequence mismatch in some embodiments, where pointer i and pointer j point to the first character of S1 and S2, respectively, and the pointing characters are not equal, pointer i is held stationary, pointer j is moved back bit by bit, and the second character pointed to by pointer j is compared to the first character in S1 in FIG. 1901. In diagram 1902, when pointer j moves to the first second character of the second comparison unit in S2, the characters pointed to by pointer i and pointer j are equal, pointer i and pointer j continue to move backward and are compared bit by bit. In fig. 1903, pointer i and pointer j point to the last character of S1 and S2, respectively, and the second comparing unit in S1 and S2 is completely matched, so that it is determined that the matching is a transcription order error, and the skipped part of the writing in S2 is marked red, and the matched part is marked green.
