  • Animation is showing the highest record in entertainment around the world and writing the history of 3D animation again. The image contents effect thanks to the proper introduction of the state-of-art digital technology, which is one of the causes of the outstanding entertainment and the factual reproduction of the images, provided an opportunity to transmit the meaning of image aesthetics, which is a virtual reality and image reproduction through the reality realization of photo medium, and to reinterpret the boundary of virtual reality. Especially, the development of digital contents technology due to scientific technologies demolishes the boundary of virtual reality and reality and creates the effect of making viewers be absorbed by realizing the virtual reality by means of 3D reality images which highlight the special characteristic of photos. The aspect of the contents technology and image aesthetics which can be interpreted in a view point beyond the existing concept of reality is found in the aura theory of Benjamin and in the Simulacres of Baudrillard. The 3D image by photo-reality herein presents various suggestions in the aspect of real existence of spatial expression, the meaning creation process of reality, the existence value of virtual images.

  • As the era of the fourth industrial revolution began, augmented reality showed infinite possibilities throughout society. However, current augmented reality systems such as head-mount display and hand-held display systems suffer from various problems such as weariness and nausea, and thus space-augmented reality, which is a projector-based augmented reality technology, is attracting attention. Spacial augmented reality requires precise tracking of dynamic objects to project virtual images in order to increase realism of augmented reality and induce user 's immersion. The infrared sensor-based precision tracking algorithm developed in this paper demonstrates very robust tracking performance with an average error rate of less than 1.5% and technically opens the way towards advanced augmented reality technologies such as tracking for arbitrary objects, and Socially, by easy-to-use tracking algorithms for non-specialists, it allows designers, students, and children to easily create and enjoy their own augmented reality content.

  • Augmented reality offers a great potential in teaching and learning through enhancing situated cognition and building indirect experience. However, existing systematic reviews are limited to studies conducted outside of Korea and fail to reflect the Korean trends. This study attempts to understand the augmented reality trends of educational research in Korea through a systematic review. The content types are also reviewed regarding situated learning. The results show that Korean studies tend to target preK-12 while many global research focus on K-16. In addition to Humanities & Arts and Science, Korean studies explored in special education. Concerning educational effects, numerous Korean studies investigated on individual learning and less focused on collaborative or situated learning. Moreover, many Korean studies used object-controlling contents. Lastly, challenges and suggestions for future research are addressed.

  • This study analyzed a group interview with six earth science teachers and eight middle school students to find out the evaluations and criteria they use to evaluate VR/AR contents (two virtual reality content and two augmented reality contents) in middle school science digital textbook. The study found the VR/AR contents were evaluated on four criteria as follows: VR/AR media characteristics; technical operation; user interface; and teaching-learning design. The evaluations can be summarized by each criterion. First, regarding VR/AR media characteristics, interesting features of VR/AR contents were considered relatively advantageous compared to other media like videos. However, its shortage of visual presence and inconvenience of using markers were mentioned as shortcomings. Second, in the technical operation criteria, teachers and students found the following conditions as technically challenging: failing to properly operate on a particular OS; huge volumes of contents in the application; and frequent freezing when using the application. Third, poor intuitiveness and lack of flexibility were found as negative aspects in user interface. Fourth, regarding teaching-learning design, the teachers evaluated whether the VR/AR contents delivered scientifically accurate information; whether they incorporated class goals set by teachers; and whether they can help students' inquiry. It turned out teachers gave negative feedbacks on VR/AR contents. The students evaluated VR/AR contents by assessing whether they help them with learning science but concluded they did not regard them necessary in science learning at school. Based on the findings, this study discusses which development direction VR/AR contents should take to be useful in teaching and learning science.

  • This study aims to verify the psychological evaluation that consumers undergo when accepting virtual fitting services while shopping online. The Theory of Interactive Media Effects (TIME) was applied to determine the impact of the perceived affordance of media on consumer response through immersion. An online survey was conducted targeting female consumers in their 20s and 30s, and 271 responses were collected and used for empirical analysis. The results of the analysis showed that interactivity and immediacy had a positive effect on telepresence. Telepresence, in turn, affected perceived usefulness and enjoyment, which then significantly affected purchase intention. In addition, some paths confirmed the moderating effect of consumer innovativeness. In consumers with high innovativeness, interactivity was found to have a greater influence on telepresence and perceived usefulness had a more significant influence on purchase intention than in consumers with low innovativeness. Conversely, in consumers with low innovativeness, perceived enjoyment was found to have a greater influence on purchase intention than in consumers with high innovativeness. The significance of this study is that it expands research on customer perception of virtual fitting services within online shopping platforms.

  • The purpose of this study is to pay attention to the expression of good and evil which has Been significantly developed out of the existing dichotomous good and evil in animation films and to identify for them. Even though 3D animation films provides us with a sense of realistic existence due to surprising technical powers, the stories contained in such films tend to remain in the limit of family films. However, recently, some films have been presented beyond such limit with a scenario that makes people introspect their inner side. Among them, this study considered the expression of good and evil of , which extended the meaning of didactic morality into the dimension of 'Philosophy of Dionysian yes', as significant for research purpose. More specifically, this study looked at and discussed this film in more details in the aspect of focusing on the value of good and evil for eliminating the boundary of the existing perspective and pursuing positive overcoming. The frame of the concept for discussion used the philosophical statements of Kant and Hegel as well as Nietzsche who explained the meaning of good and evil with Dionysian view. As to the method of research, this study attempted to understand the theoretically related concepts and discuss the meaning, along with the presentation of examples, by inputting such meaning into the expression of good and evil presented in the film. This study has the implication in identifying that an animation film, as a virtual world, plays a role of opening a new prospect for conversion of thought in our real world and expecting a future progress.

  • Purpose: Live commerce is a new type of electronic commerce in combination with live streaming services. It is expected to increase virtual presence in the context of online shopping by overcoming a lack of social interactions between sellers and buyers which have been raised as a limitation in electronic commerce. Drawing on the studies of communication media, this study examines how live commerce contributes to the increase of virtual presence which consists of telepresence and social presence. Telepresence refers to a buyer's perception that he or she is present at the physical shopping mall during live shopping streaming whereas social presence refers to a buyer's perception of social interaction with a seller which is human warm, social, sensitive, and personal. In this study, we verify key determinants of virtual presence and its consequences. More specifically, this study proposes virtual presence contributes to the increase of buyers' trust in products and further purchase intentions. Furthermore, we verify influential factors of virtual presence from the technical and influencer perspectives of live commerce. Design/methodology/approach: To test the proposed hypotheses, the partial least squares (PLS) analysis is conducted with a total of 250 data collected on users with experience in the TaoBao live streaming shopping platform. Findings: The results show that first, telepresence and social presence are increased by visibility, media richness and attractiveness in the context of live shopping streaming. Second, buyers' trust in product trust and purchase intentions are positively influenced by telepresence and social presence. Finally, buyers' trust in product has a direct, positve effect on their purchase intentions. Overall, the findings offer new insights into the studies of electronic commerce by introducting the concepts of virtual presence and media richness from the literature of communication media in the field of live commerce.
