Research On Assistant Learning System For Calligraphy Copying

Many textbooks and works on calligraphy study in our country are written from the perspective of two-dimensional plane,and regard calligraphy handwriting as a static plane image,but in fact,calligraphy handwriting is a movement track formed by writing movement.The speed and pressure of writing are the most basic factors of handwriting change,and they are also common writing indicators,which can be used to measure the similarity of calligraphy copying.But in the traditional calligraphy teaching mode,the most commonly used is the hand-in-hand mode,after students observe and memorize the strength,speed,layout and rhythm of the teacher’s writing,they can copy it on the calligraphy again and again.However,the model characters in the calligraphy books we usually use are only a static image,and lack of dynamic information when using the calligraphy.Therefore,after leaving the teacher’s demonstration,it is difficult for the scholars to speculate on the dynamic information of the model characters in the calligraphy books,such as the rhythm and speed of using the calligraphy in the process of writing.In this situation,this paper designs a test system based on digital screen equipment and wireless pressure sensitive pen equipment.The visualization scheme of pen speed and writing pressure are explored in turn.The main contents of this paper are as follows:1)The paper summarizes the research on the design of calligraphy copying assisted learning system in previous literature,quantifies the dynamic information in the writing process,obtains the numerical value,and takes the two most important dynamic variables in the writing process,namely,the speed of writing and the writing pressure,as the reference quantity,innovatively puts forward a variety of visual display schemes based on the dynamic variables,By comparing the numerical similarity of the two variables in different visualization schemes,we can get a better visualization scheme of calligraphy dynamic information,so as to improve the learning efficiency of calligraphy learners.2)According to the schemes,the system is programmed in unity3 d engine.A total of two experimental test systems have been developed,one is the speed of writing simulation experiment program,the other is the writing pressure simulation experiment program.In these two experimental systems,we can freely set the experimental times,experimental time,experimental mode and other variable factors to achieve the flexible control of the experimental program,and can save the dynamic data collected by the system to the local file.3)The collected data were integrated and statistically analyzed to draw a conclusion.In this paper,the experimental analysis process is completed in MATLAB.In this process,the least square curve fitting,Pearson correlation coefficient calculation and variance analysis are used to get the correlation of each sample data.And the speed of writing and writing pressure of these two experiments were analyzed separately and comprehensively,and the final experimental results were obtained.The experimental results are as follows: in the speed simulation experiment,the static visualization mode has better performance than the dynamic visualization mode,and the new static display scheme proposed in this paper has better data performance than the traditional display scheme proposed by predecessors.In the writing pressure simulation experiment,the experimental data show that different visualization schemes also have a significant impact on the similarity of learners’ imitation.Through the comprehensive analysis of the two,we can conclude that different visualization modes of dynamic information have a significant impact on the similarity value of user imitation,and the impact on the speed experiment is significantly higher than that on the pressure experiment.The innovations of this paper are summarized as follows:1)The paper proposes a research method to collect the dynamic information of writing for writing imitation test,which can obtain the dynamic information such as speed,pressure,pen tilt and so on.Through curve fitting processing,this method can reproduce these data in different visual ways for testers to imitate.2)Referring to the previous experiments on writing motion information,a complete experimental system for users to copy dynamic writing data is designed and implemented.Through the comparative experiment,we can get the difference of similarity degree of users for different schemes.Therefore,the calligraphy visualization scheme based on dynamic writing information really plays an important role in learners’ copying learning,which can provide a theoretical reference for the design and application of more interesting and efficient display schemes,and help calligraphy learners’ learning and the inheritance and development of calligraphy in the new era.
