Black marker cause unnatural problems between the existing various contents and marker. To solve this problem, we tested frequency of 3D objects according to the various colors and color placement. Based on this, infant's learning content system based NyARToolkit for the mobile-based augmented reality was implemented. By insert to color marker, We are solved the unnatural problems in the Implemented system. and infant can study seamlessly because concentration increases by the familiar character on the markers.

과거에는 책이나 브로마이드 형식의 학습 자료를 이용하여 유아들에게 수에 대해 가르쳤다면 휴대폰이나 스마트폰 등 휴대용 기기를 좋아하는 유아에게는 애플리케이션을 이용하는 것이 더욱 효과적이다. 이에 본 논문에서는 스마트폰을 이용하여 유아들을 대상으로 하는 수 개념 학습 애플리케이션을 설계 및 구현하였다. 수에 대해 알지 못하는 유아를 대상으로 유아가 좋아하는 색깔과 그림을 이용하여 1에서 10까지의 수에 대한 개념들을 학습할 수 있도록 콘텐츠를 제공한다. 또한 학습한 1에서 10까지의 수들의 원리를 이해하고 학습한 수들을 조합하여 활용할 수 있도록 애플리케이션을 구성하였다.

This study was conducted to evaluate the usability of augmented reality (AR) picture book for young children. The participants of this study were 17 five-year-olds attending to M kindergarten in Korea. The measurement of the usability was conducted by observation and interviews during and after children's AR picture book reading 1) usability test score such as task completed that is, reading the AR picturebook successfully, 2) children's behaviors in the process of reading the book, 3) children's response to the questions asking the level of satisfaction with the AR picture book. The result of study showed that most of children could read the AR successfully adjusting the distance and angle of AR picture book to web-camera's location. And children showed verbal and nonverbal expression such as surprise, joy, questions and frustration in reading the book. Children told that AR picture book is fun and easy to read. This study would provide the implications for the interface development and adult-child book reading of AR picture books.

The purpose of this study is to explore young children's perception of IrobiQ, the teacher assistive robot. Participants of this study were fifty 5 year olds attending 3 kindergarten centers who had experienced the robot for at least 2 years. The study was conducted based on the "the hypothesis of speech register". Each child was read a storybook by a researcher and asked to choose which one is more suitable to human speech tones and accents among a robot, a friend, and a toy. The findings of this study were that the children perceived a robot as a hybrid compound entity, not as a complete human though they perceived it closer to a human than an artificial thing. They were likely to use cognitive distinctions which is unique to human being, as the criteria to verify their answers. These results would suggest that the traditional binary ontological category(animate vs. inanimate) is reconsidered to include an hybrid entity.

The aims of this study were to examine the grounds for the appropriateness of board games in daycare centers and kindergartens based on the child-centered, play-centerd activities of revised Nuri-curriculum and provide basic resources by the case studies of board game activities in each area of the Nuri-curriculum. For these aims, it suggested the rationale of board game use in early childhood education field: first, the value as an activity with concrete objects based on developmentally appropriate practice (DAP), second, children's voluntary participation and immersion due to the competition and rewards in gamification, third, integrated experience across all areas of the Nuri-curriculum. Also, it provided various samples of the integrated board game activities for children, and reviewed the precaution, pros and cons that emerged during the play. This study discussed the possibility and direction of board game activities in early childhood education and provided implications for organizing board game activities in the education field and developing new board game contents.

The purpose of this study was to develop and test an eye tracker focusing on early childhood participants, based on the characteristics of early childhood eye tracking studies. Eye tracking collects eye movement data of the subject, which provides scientific evidence of human cognition and thinking. The researcher built a Do It Yourself eye tracker camera module from general electronic components, and used Viewpoint analysis software from Arrington Research. The researcher compared the eye tracking data between the DIY eye tracker group and Tobii Pro eye tracker group, which provides a professional eye tracking system. Eye tracking data was collected from 52 five-year old children. The average proportion of valid trials between the two groups was compared with t test, and no significant difference was found. This result indicates that the DIY eye tracker can be used to collect valid eye tracking data from young children under certain research environment.

The purpose of this study was to develop a school violence prevention program "Modujikimi" for young children to be embedded in IrobiQ, the teacher assistive robot. The themes of this program consisted of basic character education, bullying prevention education and sexual violence prevention education. The activity types included large group, individual and small group activities, free choice activities, and finally parents' education, which included poems, fairy tales, music, art, sharing stories. Finally, the multi modal functions of the robot were employed: image on the screen, TTS (Text To Speech), touch function, recognition of sound and recording system. The robot content was demonstrated to thirty early childhood educators whose acceptability of the content was measured using questionnaires. And also the content was applied to children in daycare center. As a result, majority of them responded positively in acceptability. The results of this study suggest that the further research is needed to improve two-way interactivity of teacher assistive robot.

With the development of online education due to COVID-19, the EduTech market, which combines new technologies such as AI and AR/VR in education is rapidly growing. In addition, the children's industry is steadily growing despite the decreasing birth rate every year as more and more families with one child per household are investing in their children. However, supply of contents to EduTech market is slow compared to demands that are increasing. Therefore, the purpose of this paper is to help solve these problems by developing and supporting AR kids contents with convenience, practicality, and efficiency using AR technology. AR content for supporting vocabulary learning for infants is not just an end to watching and listening, but an observation-driven model that can manipulate content directly, which attracts children's interest and helps children learn words. This paper is intended for infants from 15 months to 36 months old when full-fledged language development occurs.
