본 논문에서는 테이블탑 디스플레이을 기반으로한 RealBook에 대하여 제안한다. 전자책은 일반 종이책이 아닌 컴퓨터를 이용한 가상의 책으로써 사용자가 독서를 하는 도중 동영상 자료를 보거나 배경음악을 들을 수 있게 해주는 멀티미디어 콘텐츠이다. 또한, 테이블탑 디스플레이 플랫폼에서 사용하므로 손의 직접적인 터치를 이용하여 전자책과 사용자 간의 좀 더 다양한 상호작용이 가능하도록 한다. 테이블탑 디스플레이에서는 손가락의 터치 점을 이용하여 다양한 제스처를 정의할 수 있어서, 사용자가 기존 입력 장치에 비해 보다 효과적으로 전자책을 체험하는 것을 돕는다. 본 논문에서는 제안하는 방법은 기존 전자책과 차별화된 상호작용 디지털와 아날로그를 결함한 책(Real book)으로써 전자책에 대한 새로운 방향을 제시할 수 있고, 미디어 아트와 스토리텔링 기법을 접목시켜 사용자에게 정보 전달뿐만 아니라 예술과 오락 등을 제공할 수 있다. 앞으로 컴퓨터와 사용자간의 상호작용을 원활하게 할 수 있어 다양한 어플리케이션 개발에 활용될 수 있고 향후 미래 지향적 시스템이 될 것이다.

This paper proposes AR stone tower content, an experiential content based on wearable augmented reality (AR). Although wearable augmented reality is gaining attention, the acceptance of the technology is still focused on specialized applications such as industrial sites. On the other hand, the proposed AR stone tower content is based on the material of 'stone tower' so that general users can relate to it and easily participate in it, and it is organized to utilize space in a moving environment and find and stack stones based on natural hand gestures. The proposed AR stone tower content was implemented in the HoloLens 2 environment and evaluated by general users through a pilot exhibition in a small art museum. The evaluation results showed that the overall satisfaction with the content averaged 3.85, and the content appropriateness for the stone tower material was very high at 4.15. In particular, users were highly satisfied with content comprehension and sound, but somewhat less satisfied with object recognition, body adaptation, and object control. The above user evaluations confirm the resonance and positive response to the material, but also highlight the difficulties of the average user in experiencing and interacting with the wearable AR environment.

The purpose of this study was to define an interactive learning object of ILO through implementation of learning object content standardization technology for the reuse of interactive tools between learners, and to develop I(Interactive)-HTTP for the ILO to properly communicate with LMS. 1-HTTP developed here was enabled to keep connection status during the entire session by improving the existing HTTP with its stateless connection property. This ceaseless connection made it possible to provide users with the real-time interactivity between learners that happened frequently in the ILO. Also, because the I-HTTP was an expanded version of HTTP, it was possible to conduct general HTML documentation as well as ILO. In particular, the standardized launch process between LMS and ILO was embodied in adding the INIT, GETVAL, SETVAL, COMMBT, FINISH methods in the protocol, and the results from the interactivity between ILO learners were channeled to the database storage to save them through separately defined data models.

The purpose of this study was to analyze the quality of 67 kinds of e-learning contents in an attempt to boost the effectiveness of distance teacher training. As a result of analyzing, the e-learning contents were rated highest in terms of 'training content,' followed by 'instructional design,' 'teaching & learning strategies,' 'evaluation' and 'interaction.' The scores of 'teaching & learning strategies,' 'evaluation' and 'interaction' were below 80 that was the standard of quality certification. In mean comparison(ES) of contents quality level between certified contents and non certified contents, 'instructional design' had the largest ES(effect size), followed by 'teaching & learning strategies,' 'evaluation'. In the analysis of evaluation factors, most of factors had a large effect such as 'webpage layout', 'selection of instructional design'. The findings of the study are expected to suggest what improvements should be made in the development of e-learning contents for distance teacher training.

Due to the development of mobile devices and streaming technology, many changes in consumption patterns have appeared. In addition, social impact is becoming an era of non-face-to-face consumption due to the panthermic environment of COVID-19. Accordingly, in line with the non-face-to-face consumption trend, we focused on the importance of live commerce, which is emerging as a new distribution channel, and tried to investigate the causal relationship that the characteristics of live commerce and show hosts have on purchase intention. The respondents of this study were 235 general adults of live commerce users. Interaction, economics, entertainment as the characteristics of live commerce and attractiveness, professionality, and awareness as the characteristics of show hosts were set as independent variables. Purchase intention was set as the dependent variable, and content flow was set as the mediating variable. As a result of the study, it was found that the characteristics of live commerce such as Interaction, economics, entertainment, and the characteristics of show hosts such as attractiveness, professionality, and awareness all had a positive (+) significant effect on purchase intention. The impact was shown in the following order: entertainment of live commerce, awareness, attractiveness, professionality of show hosts, economics, interaction of live commerce. In addition, the results of the mediating effect of content flow on purchase intention are as follows. Content flow was found to play a mediating role between interaction, entertainment, attractiveness, professionality, awareness and purchase intention. On the other hand, economics was analyzed to have no mediating effect. The implications of this study are as follows. Companies and show hosts that sell products in live commerce should sell products that can inspire consumers rather than simply sell products. In addition, it is considered that content that provides entertainment and attractions gives pleasure to consumers. If not only a well-recognized show host, but also people with high recognition in various fields such as influencers and creators, become show hosts, consumers' content flow and purchase intentions will increase. And vendors must offer interesting content development and reasonable prices. Show hosts need to focus on active communication with consumers.

초등 교육과정에 소프트웨어 교육 내용이 포함되는 2015 개정 교육과정의 시행을 앞두고, 학교 현장의 교사들은 이에 대한 지도 준비 수준이 낮으며 소프트웨어 교육 관련 교수 학습 자료도 부족하다고 느끼고 있었다. 이에 본 논문에서는 체험을 주 내용으로 하는 초등학교 프로그래밍 영역에 활용이 가능한 웹캠 기반 스크래치 프로그래밍 교육 콘텐츠를 개발하였다. 이 때 프로그래밍 흥미를 높일 수 있는 방법으로 웹캠을 사용하여 사용자의 움직임과 상호작용이 가능한 콘텐츠를 제작하였으며 총 10차시로 구성하였다. 추후 본 논문에서 제안한 교육 콘텐츠를 초등학생들에게 적용하여 교육적 효과를 검토할 것이다.

This paper presents a fire and smoke animation system using stable fluid animation techniques. Stable and fast fluid simulation methods are developed in PC and console games, but fluid simulation and interactive fluid models still have many problems. We studied and implemented physics-based models for fluids like fire and smoke effects using mobile 3D system. The mobile platform of our system is WIPI, which are the standard mobile platform in Korea also we adopted NF3D API for our 3D programming API.
