In this way, after a large number of statistical data in the processor 4 are read at once by means of the handheld device 9, the user can clearly see the distribution of the number of words written in different time periods in the handheld device 9.
The method for estimating and counting the word number in the writing process by adopting the pen capable of counting the word number comprises the following steps: when the pen is in an idle state, the pen core 2 is kept in a separation state from the pressure sensor 3 under the action force generated by the elastic part; when a user starts writing and in the continuous writing process, namely in the continuous switching process between different strokes, the front end of the pen core 2 is in continuous interval contact with the paper surface, so that continuous interval pressure is generated, the acting force of the elastic part is repeatedly overcome, the tail end of the pen core 2 is in repeated contact with and separated from the pressure sensor 3, and the pressure sensor 3 is triggered to generate a continuous pressure signal; meanwhile, the statistical module 41 in the processor 4 performs statistics on the pressure signal, that is, the number of written strokes is counted; when the statistical operation of the pressure signal is completed, the statistical value in the statistical module 41 and the preset stroke number average value are called by the calculating module 42 in the processor 4 to calculate the number of words to be written, so as to obtain the final word number estimation value.
Preferably, in this embodiment, the preset stroke number average value in the processor 4 is set in an adjustable manner, that is, the user can adjust the stroke number average value in the processor 4 according to his writing habit, for example, the continuous stroke condition when the user writes a chinese character or a letter, so as to conform to the writing habit of the user and improve the estimation statistical accuracy of the word number. According to 2500 common words and 1000 common words given in the modern Chinese common word list, the stroke number average value of 3500 words is continuously distributed between 1 and 24, wherein the stroke number average value of more than 200 words in the 2500 common words is distributed between 6 and 12 and accounts for 72.5%, the stroke number average value of more than 300 words in the same stroke number average value is only 8 and 9 and accounts for 25.5%, and the stroke number average value of more than 100 words in the 1000 common words is distributed between 10 and 12 and accounts for 35.5%, so that a user can adjust and modify the stroke number average value based on the statistics according to the self writing habit, such as continuous stroke condition and different types of writing contents, thereby meeting the self writing habit of the user. For example, after the user uses the pen for the first time or performs the initialization process, the stroke number average value in the processor 4 may be repeatedly adjusted and corrected by writing a limited number of words in advance according to the writing habit and the type of the written content of the user, so as to determine an optimal stroke number average value, and the stroke number average value is input into the processor 4 by means of the handheld device 9, so as to improve the accuracy of the word number estimation statistics when a large number of characters are written continuously.
Preferably, a unit period may be preset in the processor 4 by using the timing module 43, so that the processor 4 performs continuous accumulation statistics on the pressure signal generated by the pressure sensor 3 in each complete unit period, and when the unit period is over, the processor 4 stores the data in the unit period and the statistical unit 41 performs the continuous accumulation statistics on the pressure signal again, and the stored data is transmitted to the handheld device 9 when the handheld device 9 is connected with the processor 4 again, thereby realizing the automatic continuous word count statistics. In addition, with the aid of the marking of the pressure signal by the timing module 43, the user can also clearly understand the distribution of the number of words written in the previous unit cycle when reading data subsequently by the handheld device 9.
In addition, in the process of carrying out continuous counting of the word number in the unit period, the user can operate the control button 7 at any time to enable the processor 4 to carry out temporary counting of the word number written in the specific time period under the condition of keeping the continuous counting of the original word number, so that the number of the word number written in the specific time period can be quickly estimated, and the use convenience is improved.
Next, the word count in the process of writing a chinese character by using the pen capable of counting word count of the present embodiment is verified:
firstly, a common Chinese character comparison table is established, and the common Chinese characters are classified according to the stroke number. The comparison table is established according to the modern Chinese commonly-used character table in the verification process, and can also be established according to commonly-used Chinese characters publicly obtained from other documents.
Then, a Chinese character database is selected and established. Daily contact text data including current affair news, sports news, life reports, literary news and the like are collected through a network, and the obtained texts are typeset and arranged according to a uniform format, wherein the Chinese character collection amount is about 1 ten thousand.
Then, the Matlab software is used for carrying out the association of the comparison table and the database, and taking the Chinese characters in the comparison table as a standard, the corresponding Chinese characters are selected from the database, meanwhile, the Chinese characters selected from the database are classified according to the stroke number of the Chinese characters, and finally, a distribution curve graph with the abscissa as the stroke number and the ordinate as the frequency number as shown in FIG. 3 is obtained. According to fig. 3, the distribution of the number of strokes of a common chinese character follows a normal distribution and the stroke mean is 7.0377.
Finally, 10 students in different professions are selected to use the pen of the embodiment to write 100 Chinese characters (including punctuations) with different contents according to the daily writing habit of the students, and finally word number estimation statistics is carried out according to the stroke average value of 7.0377. Wherein, the pen according to the embodiment automatically counts strokes and calculates the word number by using stroke mean estimation of 7.0377 and the word number by using stroke mean calculation of 7.0377, and the error between the word number obtained by counting strokes by students themselves is within 5%. Therefore, the accuracy of word number estimation statistics by using the pen of the embodiment is more than 95% through the verification.
