Research On Interactive Structure And Evaluation For Stroke Force Of Handwritten Chinese Character Of The Writing’s Teaching System

Most of Existing Electronic Devices only own a single text written exercises inwriting process, or the ability of intelligent tutoring is extremely limited. According tothe phenomenon，this project has developed a Multi-function Text Writing ExercisesIntelligent Tutoring System combined of compulsory education with multi-languageoptions, multi-practice methods choice, and multi-exercise formats choice and so onat the same time, the system also own functions giving the writing of a qualityassessment after the exercises are completed, counseling on the errors in the writingprocess and can be networked interactive.Interaction Structure and Writing Strokes Force are two key technologies of thisproject. Whether the system can accept by user or has strong vitality, system andmechanism of user interaction plays a vital role. This paper studies the interactivestructure and force of Chinese characters strokes analysis algorithm from aspects inexercises to facilitate using, intelligent technology, writing paper simulation etc. Thekey content has counseling scene layout, page display, picture vector preservationsubmission and handwriting elimination. Writing Strokes Analysis is one of maintechnical means to give an effect scores to user’s written, this paper has analyzed theproblem during the writing on resistive touch screen, and put forward a fuzzyevaluation method of strokes of Chinese characters. The main contents include thebuild of membership template, the selection of fuzzy subset selection, and thegeneration of template parameter and evaluation implementation. The experimentsshow that the interaction structure not only inherited the advantages of paper writingand playing electronic equipment strengths, through the interactive structure to realizethe man-machine interaction, so that the machine can text exercises were written inthe intelligent tutoring. Most of all, its character of interactive real-time made it ableto conform to the practice population’s writing habits and the social cognition. Thedisplay analysis results of Chinese character strokes based on fuzzy method arebasically consistent with the subjective evaluation of the effectiveness by peoples, andhave strong objectivity, robustness. Moreover, it can also be extended to otherlanguages.The main innovation of this article can summarized as follows:1Design and implement a simulation of the paper-based text writing exercises, which has several functions such as exercise format printing, the layout of the way topractice, the selection of the paper page, the erase of the writings and the interactiveof the comparing exercises. The layout of the practice is strictly in accordance withthe text order to the nine-year compulsory education textbook conforming to theprogress of teaching. In the premise of people’s social cognition and daily habits onthe writing practice, we use interactive "electronic-paper" to accomplish our design,thus avoiding the drawbacks of the static practice paper and playing the advantages ofthe electronic equipment, which can be used repeatedly and dynamically.2Realize the save and submit of the practice picture in the vector form, whichcompose the dynamic properties characteristic parameters of the system and thepracticing handwriting status to vectors, we store and transmit them so as to greatlyreduce the amount of the data to send and improve the transmission speed, at the sametime, with this method we can restore the site in no distortion.3Put out a Writing Strokes Force Fuzzy Evaluation method based on the strokesforce. There has been a saying of “force of strokes’ in the traditional Chinesecalligraphy aesthetic. But such writing analysis which uses computer technology totext is still blank. The existing achievements of Chinese characters only focusing onthe gravity, the length, glyph geometric structure figures structure analysis，the forceof strokes or the abstract concept is still not involved. In this paper the authors studiesan analysis method to analyze the stroke line feature point on a touch screen based onfuzzy. Through extracting the information of key points of the strokes in handwritingtemplate word to calculate its membership, building a fuzzy pattern matrix, thenmarching the real write Chinese characters membership with the membership datatemplate to calculated integrated strokes force evaluation. The experiment resultsshow that the method tallies with the teacher subjective evaluation method. Becausethe words is made of lines, so extended to other styles in literary also have strongrobustness.This topic comes from the Hunan province university innovation platform ofOpen Fund Project，" Networked interactive multifunctional format writing systemand method"(09K040).Topics’ content are important part of invention patents (ZL201010149767.2).
