This study presents a way to design picture books that allow children to experience indirectly through realistic media at home and educational institutions for children whose direct experiences and activities are reduced offline in the post-COVID-19 era. The development and popularization of realistic media such as AR continues to be grafted and developed in the picture book field, and the advantage of this picture book is that children at the stage before learning letters can feel the story and character situation of the book through the experience of AR and QR animation in the picture book. In this process, you can get access to imaginary areas that can not be experienced in flat-panel illustrations with spatial animation to help improve the scalability and literacy of the story contained on the page. Children's education through realistic animation can increase the learning effect and needs to continue after COVID-19. Therefore, by presenting the process of viewing and experiencing picture books using AR and QR, the result of the study suggests that the design process of realistic picture books is not just a combination of technology, but a process of expanding children's perception and imagination. This study aims to find out how visual perception is designed differently by analyzing the differences and characteristics of each animation design, focusing on the AR and QR picture book "Where am I?" published by the researcher, and to contribute to the active introduction and development of realistic animation in the field of children's picture books and education.

This study was aimed to compare teacher's and mother's literacy beliefs, perception of picture books, and frequency of reading activities, and examine how these variables affect the interaction for reading picture books with preschoolers. The results of the survey from 120 teachers and 168 mothers who have 5-year-olds in Gyeonggi-do and Incheon-si are as follows. Teachers' literacy beliefs were closer to whole language beliefs than were mothers'. Teachers and mothers both fully realized the importance of reading aloud picture books to children with no difference between each other. The level of teachers was higher than mothers' in terms of pleasure of reading picture books. Mothers thought that it is important to reflect on preschoolers' development level, individual conditions, and daily lives when choosing picture books. On the other hand, teachers believed that the popularity of the book is more important. Overall, teachers perceived more benefits of reading picture books than mothers. Mothers reported more extensive interaction when reading books with preschoolers than teachers, while teachers spent more time on reading activities with preschoolers than mothers. Teachers' and mothers' frequency of reading activities and perception about the benefits of reading picture books had effects on their interaction for reading picture books with preschoolers.

This paper describes a 3-DTIP(3-D Tour Into Picture) using depth map for a Korean classical painting being composed of persons and landscape. Unlike conventional TIP methods providing 2-D image or video, our proposed TIP can provide users with 3-D stereoscopic contents. Navigating inside a picture provides more realistic and immersive perception. The method firstly makes depth map. Input data consists of foreground object, background image, depth map, foreground mask. Firstly we separate foreground object and background, make each of their depth map. Background is decomposed into polygons and assigned depth value to each vertexes. Then a polygon is decomposed into many triangles. Gouraud shading is used to make a final depth map. Navigating into a picture uses OpenGL library. Our proposed method was tested on "Danopungjun" and "Muyigido" that are famous paintings made in Chosun Dynasty. The stereoscopic video was proved to deliver new 3-D perception better than 2-D video.

The purpose of this study is to investigate the perception of elementary students' 'global environment'. The research method used the Sementic Network Analysis method of the global environment elements which appeared in the students' explanation about the picture and the picture that emerged about the 'global environment'. The results of the study are as follows. First, as a result of analyzing the students' explanation of the pictures along with the pictures of the students, the elementary students were perceived negatively about the global environment such as 'environmental pollution', 'global warming' and 'trash problem'. Second, as a result of analyzing the image of the global environment expressed in the picture, there were many images expressed from a everyday viewpoint rather than a macroscopic viewpoint, and there was a tendency to express the earth personified. In addition, the picture expressing the clean earth environment expressed the most trees with natural environment elements and expressed the healthy earth with various natural elements such as sea, mountain, and land. Third, as a result of analyzing the difference of perception of global environment by grade, it was found that the difference of perception of global environment by grade was not much different.

To investigate the relationship between voice and the image created by the voice, a perception experiment was undertaken in which voices of 8 males and 8 females reading a fairy tale were recorded and presented to 100 subjects along with the speakers' pictures. Two kinds of pictures were taken: one, a whole-body picture, and the other, a face-only close-up picture. Subjects were asked to match each voice with its owner. The results showed that out of 8, more than 4 were matched correctly. And the correct rate was higher when the voices were matched against the whole-body pictures than against the face-only pictures. In addition, it was noted that far more people picked a single voice as the most 'favorite' one than they picked one picture as the most 'favorite' image.

The aims of this study are to investigate the environmental perception of elementary school students through picture drawing and associated words about environment, and analyze whether there are differences in the environmental perception according to living places and grades. The drawing of 230 students are analysed and categorized into the criteria. The results are as follows: a number of students realized as images associated with natural environment for words related to environment. In the pictures of the 'positive environment', expression frequencies of natural environment and living things were higher than ones of artificial environment and non-living things. On the other hand, there were many pictures expressed as pollutions of waste, air and water in the pictures of the 'negative environment'. Comparison of environmental perception between rural and urban students showed a significant difference all in the two criteria. There was, however, no difference in the environmental perception between grades. Therefore, it is suggested that student's minds about the sentimental situation can be studied and they can be guided in positive directions to lead their future life in environment-friendly education rather than pollution education.

This paper presents a 3D stereoscopic TIP (Tour Into Picture) for Korean classical paintings being composed of persons, boat, and landscape. Unlike conventional TIP methods providing 2D image or video, our proposed TIP can provide users with 3D stereoscopic contents. Navigating a picture with stereoscopic viewing can deliver more realistic and immersive perception. The method firstly makes input data being composed of foreground mask, background image, and depth map. The second step is to navigate the picture and to obtain rendered images by orthographic or perspective projection. Then, two depth enhancement schemes such as depth template and Laws depth are utilized in order to reduce a cardboard effect and thus to enhance 3D perceived depth of the foreground objects. In experiments, the proposed method was tested on 'Danopungjun' and 'Muyigido' that are famous paintings made in Chosun Dynasty. The stereoscopic animation was proved to deliver new 3D perception compared with 2D video.

The layout in picture book is a visual statement that arouses children's psychological reaction upon pictorial positions and those disposition, and that indicates a correlation between theme and background and characters' movements. This study firstly confirmed that children's perception and experience are variously formed according to age, past experience, psychological action, physiological impulse, mentality, growth environment, etc., in order to analyze how the pictorial layout in children's picture book has influence on children visually and psychologically. Likewise, visual and psychological perception was carried out targeting on the children between 4 and 7 years old, based on the perceptive specific and process that have been studied by previous researchers. In addition, the children's picture books published overseas or domestically were presented as the related cases, in order that the facts analyzed may be drawn to harmonious and effective pictorial layout. Lastly, it is expected that the conclusion suggested by this study may be of help to illustrators to design picture books individually and creatively, as well as be applied to studying effective expression in the educant who learn about illustration.

Relating to grasping sequential landscape characteristics in consideration of the behavioral characteristics of the subject experiencing visual perception, this study was made on the subject of main walking line section for visitors of three treasures of Buddhist temples. Especially, as a method of obtaining data for grasping sequential visual perception landscape, the researcher employed [momentum sequential viewpoint setup] according to [the interval of pointers arbitrarily] and fisheye-lens-camera photography using the obtained omni-directional angle visual perception information. As a result, in terms of viewpoint selection, factors like approach road form, change in circulation axis, change in the ground surface level, appearance of objects, etc. were verified to make effect, and among these, approach road form and circulation axis change turned out to be the greatest influences. In addition, as a result of reviewing the effectiveness via the subjects, for the sake of qualitative evaluation of landscape components using the VR picture image obtained in the process of acquiring omni-directional angle visual perception information, a positive result over certain values was earned in terms of panoramic vision, scene reproduction, three-dimensional perspective, etc. This convinces us of the possibility to activate the qualitative evaluation of omni-directional angle picture information and the study of landscape through it henceforth.
