아두이노와 저가형 생체신호 증폭기를 사용하여 시선추적실험을 실시하고 결과를 분석하였다. 본 연구에서는 간단한 4방향의 시선이동 인식실험과 함께, 시선을 사용하여 영어 알파벳 등을 직접 쓰는 eye-writing 인식실험을 함께 진행함으로, 새롭게 구성한 안구전도 측정장치의 실용성을 평가하고, 더 나아가 저가형 안구전도 장치가 eye-writing과 같은 복잡한 사람-컴퓨터간 상호작용도구로 활용될 수 있는지를 분석하였다. 실험을 위해서 PSL-iEOG와 아두이노를 사용하는 저가형 안구전도 측정장치가 구성되었으며, 패턴분류를 위해 dynamic positional warping과 웨이블릿 변환이 사용되었다. 실험 결과, 저가형 측정장치는 비교적 단순한 알고리즘만으로도 외부 잡음이 유입되지 않은 경우 90%에 가까운 정확도로 시선방향을 인식할 수 있었으며, eye-writing의 경우에도 5개 패턴에 대해서 90%의 중위 정확도를 달성할 수 있었다. 그러나 패턴의 숫자가 증가함에 따라 정확도가 매우 감소하여, 다양한 패턴의 직접적인 입력이라는 eye-writing의 장점을 부각하기 위해서는 저가형 장치에 특화된 알고리즘의 개발 등 추가적인 연구가 필요할 것으로 여겨진다.

Writing letters or patterns on a virtual space by moving a person's gaze is called "eye writing," which is a promising tool for various human-computer interface applications. This paper investigates the use of conventional eye writing recognition algorithms for the purpose of user-independent recognition of eye-written characters. Two algorithms are presented to build the user-independent system: eye-written region extraction using wavelet coefficients and template generation. The experimental results of the proposed system demonstrated that with dynamic positional warping, an F1 score of 79.61% was achieved for 12 eye-written patterns, thereby indicating the possibility of user-independent use of eye writing.

This study examined the influences of eye-contact upon the relationship between mothers' control behaviors and emotions of preschool children. The participants of this study were 66 children aged 6, and their mothers. The children and mothers were observed taking part in a writing task for 15 minutes, and two coders analyzed the amount of eye-contact between children and mothers, mothers' verbal and nonverbal support and coercive control, and children's emotions in the task setting. The results showed that mothers' coercive control and nonverbal support significantly accounted for children's negative and positive emotions, respectively. In addition, the interaction between eye-contact and mothers' verbal support was significant. In particular, mothers' behaviors significantly affected children's emotions only when eye-contact occurred. Mothers' behaviors in the absence of eye-contact did not affect children's emotions. The discussion section included an analysis of the social function of eye-contact on the verbal and nonverbal communication between mothers and children, and suggestions for future study were also presented.

This paper proposes a method of utilizing convolutional neural network to classify the images of Bender Gestalt Test (BGT), which is a tool to understand and analyze a person's characteristic. The proposed network is composed of 29 layers including 18 convolutional layers and 2 fully connected layers, where the network is to be trained with augmented images. To verify the proposed method, 10 fold validation was adopted. In results, the proposed method classified the images into 9 classes with the mean f1 score of 97.05%, which is 13.71%p higher than a previous method. The analysis of the results shows the classification accuracy of the proposed method is stable over all the patterns as the worst f1 score among all the patterns was 92.11%.

1. Objectives: We aimed to derive constitutional facial characteristics with front and side picture of the people in this study 2. Methods: Through November 2007 to July 2009, we obtained front and side face photograph data of 715 male/female constitution confirmed subjects within the age range of 10-80 from 19 oriental medical facilities in the country. According to sex, we divided the subjects into two groups, real constitution group and non-constitution group. We analyzed significant variables of distance, angle and ratio of facial point through unpaired T-test. 3. Results: There are different significant variables according to Sasang Constitution and even though they are much different between sex, the interpretation of the meaning of those variables are similar with the written characteristics of ancient Writing. The face size of the Taeeumin is bigger than that of the non-Taeeumin, and especially they have long length from mouth to mandible angle. Soeumin have small jaw area, long philtrum and narrow facial feature like egg. Soyangin has developed forehead and glabella, short jaw, long eye side. Taeyangin has developed forehead, weak nose especially side end of nose, long eye side. 4. Conclusions: Sasang Constitutional facial characteristics are different between man and woman but there are much similarity with the facts as known on the interpretation of significant variables characteristics.

This study will explore the application of the Korean alphabet 'Hangul' and its calligraphy on fashion design. Hangul is well known for its great formative characteristics. Its calligraphy has unique features that express the implicative meaning of the Korean language while simultaneously displays beautiful shapes that draw the viewer's eye. When Hangul calligraphy is applied on the pattern design, it can be an excellent opportunity to demonstrate the visual beauty of Hangul. The purpose of this study is to develop the pattern designs that utilize the Hangul calligraphy and apply them in various fields of fashion. The detailed concepts of this study are as follows. First, the theoretical concepts and characteristics of both Hangul calligraphy and pattern design will be understood. Second, the aesthetic characteristics of calligraphy will be drawn by case analysis on the artworks of famous calligraphers such as Kim Jong-geon, Kang Byeong-in, Lee Sang-hyeon, Lee Gyu-bok and other representative calligraphers who design the beauty of Korean calligraphy by handwriting and brush-writing. The obtained results will be used to explore the desirable direction of fashion design. Third, eight pattern motif fashion works that utilize Hangul calligraphy in accordance with the arrangement of different characteristics of fashion design will be presented.

The most important environment of human being is the human being itself. So we have been sensitive to the appearance of ours and others at the same time. This writing aims for locating origins of the face and discerning differences [1] between the face of humans and those of other animals [2]. The face assumes a substantial significance not merely as a body function, but, above all, a means of expressions and features being looked at. The face is an important means of communication to humans as social animals. Knowledges about the various faces of the face are useful to become a efficient specialist as an extensive generalist because the face is a regular patron to the plastic surgery. The face in Korean consists of two elements of eol (the soul or the mind) and gul a residing place). When Wittgenstein says "the face is the soul of the body," his semantics corresponds to the Korean meaning. The meaning of the face in Korean is summed up in five ways. (1) the head or the front of the face with the eye, the nose and the mouth, (2) reputation or honor, (3) the general description of the psychological state, such as "the face of sadness", (4) a figure person representing a particular area, such as "Sun Dong-yul is the face of the Korean baseball community," (5) the primary imagery of the things and the event, such as "He is the face of the 4.19 Revolution." As such, the word "face", referring to a body part, extends its usages in a wide variety of contexts. What image do you convoke when you think of a person? With rare exceptions, you are most likely to invoke the face of the person. The face has come to be a byword for one's reputation or honor, and a pronoun for an expression of the essence of the thing and the event. This is presumably true of other languages. That is because human beings are equipped with the universal rule of language. A comprehensive understanding of the face is a must for cosmetic surgeons whose main responsibility is to sculpt and repair the face (Fig. 1).
