온라인 필기 문자의 경우에는 필기의 변형이 심하고 문자간의 분리가 힘들기 때문에 인식률이 낮은 실정이다. 본 논문에서는 영문 대문자의 자유로운 필기를 인식할 수 있는 방법으로 영문 대문자의 필기시에 발생하는 획간 조합의 특징을 사용하여 인식하는 알고리즘을 제안한다.

The objective of this paper is to evaluate most useful feature vector space using the angle, velocity and location features from gesture trajectory which extracted hand regions from consecutive input images and track them by connecting their positions. For this purpose, the gesture tracking algorithm using color and motion information is developed. The recognition module is a HMM model to adaptive time various data. The proposed algorithm was applied to a database containing 4,800 alphabetical handwriting gestures of 20 persons who was asked to draw his/her handwriting gestures five times for each of the 48 characters.

This Paper proposed the development of new magnetic sensor and recognition system to expendite pattern recognition of a handwriting character. Received character graphics should be performed the session and balancing and no extraction of end points, bend points and juntions separately. The Artifical intelligence algorithm is adapted to structure snalysis and recognition process by individual basic letter dictionary except for the handwriing character graphic dictionaryimproving error of recognition algorithm and enomous dictionary for generalization. In this Paper, recognition rate of the received character are compared with pre registered character at letter dictionary for performance test of magnetic ball sensor. As a result of unicode conversion and eomparison, the artificial intelligence study have recognition rate more than 95% at initial recognition rate of 70%.

Sojeon, Son Jaehyung(1903~1981) was interested in the composition of the classical writing style of Han-gul and its merits in the operation of the brush. And a genius, modern sense of sculpture and ingenious ideas applied to the calligraphy. Thus, he succeeded Tonggukjinche by sublimating it into a unique Handwriting pure and humorous. Sojeon Hangul Calligraphy is exaggerated in consideration of the change of direction, thickness and length of the stroke. There is nothing strange about law and organization and express the great beauty of the great art of harmony and change. Sojeon's contribution is significant in that it has not only become a model for the development of Han-gul calligraphy, but also created a new area of space in modern calligraphy.

Zhang Yu was a famous Taoist priest and poet in Yuan Dynasty, compared with the identity of Taoist and poet, his handwriting had greater influence in history. According to the relevant historical data, people at that time were mainly attracted by his Taoist identity and poetic talent. However, if we considered him as a poet,or a calligrapher to inspect,it would be often easier than facing a Taoist priest. Zhang Yu's poems and relationships can be used as some clues for our investigation of his calligraphy activities,not only would it not affect us to judge the value of his calligraphy, but also we will comprehensively and objectively analyze his calligraphy works. His early calligraphy closely followed Zhao Mengfu, in his later years, when he met Yang Weizhen, the style of writing changed greatly.During this period, what kind of changes and fundamental influence had on Zhang Yu's life and book learning thoughts experienced. Our contributions to this paper are as follows.To solve this issue,this passage will try to find clues from several representative figures and representative calligraphy works of Zhang Yu, and draw on the research results of relevant scholars to discuss the identity of Zhang Yu as a Taoist priest and the origin and style characteristics of his handwriting and probed into the status and influence of his calligraphy in history.

SCRIPT (Symbol/Character Recognition In Pen-based Technology) is an algorithm for on-line recognition of handwriting Hangeul. English upperacase letters, decimal digits, and some keyboard symbols. The shape of handwriting symbols has a large variation even when written by the same person. Though the feature analysis approach using a conventional decision tree is efficient, it is not robust under shape variations and prone to misclassification. Thus, a new method to overcome this shortcoming is necessary. In this paper, a feature analysis algorithm using two fuzzy decision trees which utilize the hierarchical property of the pattern is proposed. The first tree is used to represent the stroke shape, and the other tree is used to represent the relation between the strokes. since this method stores various possibilities. it is robust to shape variations and can readily modify false selections. In addition, there is a large increase in the recognition rate of high-level patterns due to low-level candidated. Experimental results show 91% recognition rate for Hangeul at the recognition speed of 0.33 second per character, and the recognition rate of alphanumerics and some keyboard symbols is 95% at 0.08 second per symbol. This is 8~18% increase in the recognition rate over th method not applying fuzzy decision trees.

The effort for identifying personal information for example one's personality, based on one's handwriting has been continued in foreign countries, however, there is no research on the graphology for Korean in Korea. In the area of handwriting analysis, of course, they have made attempts to identifying people depended on expert's individual ability or judgment. For these reasons, the academic approach is needed for the graphology for Korean. In this thesis, we performed the frequency analysis, test of difference, cross tabulation analysis, factor analysis, correlation analysis, regression analysis and logistic regression analysis by using the data on the test of personality diagnosis based on 5 factors method and writing habits such as the size and slope of letters for 339 adults. It can be shown that the 5 factors method has high consistency and reliability, so we accept these 5 factors as the personalities. In cross tabulation analysis, it is found that there is significant relationship between sex and the size of letters, hometown and the margin, job and habit. The correlations between 5 factors are very high and we can find the useful relationships between 5 factors and writing habit through regression analysis and correlation analysis. It is difficult and impossible to compare the Graphology between English and Korean because there are various interpretations and structures of Korean that is much different from those of English. But it is very important to try to test and analyze the Graphology in Korean to found the basic theories at the present stage when there is no research on the graphology for Korean.

Objective : The purpose of this study was to investigate the effect of proprioceptive-vestibular based sensory integrative intervention on handwriting and fine motor function in elementary school students in grades 1 to 3. Methods : In this study, eight students in an elementary school in Busan were enrolled. The intervention was conducted twice a week from May to October, 2016, and a total of 14 intervention sessions were conducted. In order to evaluate the writing ability and the fine-motor exercise ability before and after the intervention, the fine-motor movement items of the Korean alphabet writing test and the Bruininks-Oseretsky Test of Motor Proficiency (BOTMP) evaluation were used. Results : There was a statistically significant difference between the total scores of consonant writing and the Korean alphabet writing assessment after the intervention. In BOTMP-Fine motor, the response speed items showed statistically significant difference. Visual-motor control scores increased during intervention, but the statistical significance was not found. Conclusion : Sensory integration interventions might have positive effects on elementary school students' writing skills and fine motor functions.

The field of handwriting recognition has been researched for many years. A hybrid classifier has been proven to be able to increase the recognition rate compared with a single classifier. In this paper, we combine support vector machine (SVM) and hidden Markov model (HMM) for offline handwritten numeral recognition. To improve the performance, we extract features adapted for each classifier and propose the modified SVM decision structure. The experimental results show that the proposed method can achieve improved recognition rate for handwritten numeral recognition.
