최근 WiBro, HSDPA 등의 통신망을 통한 휴대 인터넷이 광대역화 되고, 방송 기술의 디지털화로 인해 기존의 단순 AV 중심의 모바일 방송 서비스를 탈피하여 음성, 영상, 이미지, 텍스트 등의 다양한 멀티미디어 서비스 제공과 이들간의 대화형 기능을 제공하는 리치미디어 서비스가 각광을 받고 있다. 이러한 응용 분야를 위해서 다양한 멀티미디어 데이터의 시공간적인 배치 및 동기화를 위한 기술 규격으로 MPEG-4에서는 BIFS와 LASeR를 제공한다. BIFS는 2D 및 3D를 포함하는 보다 광범위한 멀티미디어 콘텐츠에 대한 장면 기술 표준이며, LASeR는 자원이 부족한 휴대전화와 같이 디스플레이 크기가 작고, 네트워크 대역폭도 작은 단말을 대상으로 하는 2D 전용의 장면 시술 표준이다. 본 고에서는 제한된 대역폭과 낮은 성능의 단말과 같은 모바일 방송통신 환경에서 리치미디어 방송 서비스를 제공하기 위한 최신 리치미디어 방송 서비스를 위한 요소기술 및 표준화 동향을 살펴보고, 최신 리치미디어의 국제표준인 LASeR에 기반한 모바일 리치미디어 방송 기술 개발 현황에 대하여 살펴본다.

This study defines the pipeline for digital fashion contents production using CLO 3D, a 3D fashion design software that supports virtual clothing visualization as a cutting-edge simulation technology for fashion, and vuforia, a mobile platform augmented reality (AR) development kit for creating AR applications. The proposed production pipeline is organized in a method to produce a virtual clothing model through CLO 3D software through works of patterns, sewing lines, textures, etc., and AR contents based on computer vision techniques using the functions and properties of vuforia development kits in the Unity engine development environment. In addition, we present application method that can be practically utilized from the perspective of practical users, such as fashion designers and directors, by creating a new type of AR digital fashion contents directly as a flow of the defined production pipeline.

This study investigated changes in behavioral performance before and after watching a multi-view 3D content by using auditory stimuli based on the selective attention theory in order to quantitatively evaluate 3D visual fatigue. Twenty-one undergraduates were asked to report on their current visual and physical condition both in the pre- and post-experiment. A selective attention task was conducted before and after mobile 3D viewing to compare the changes in performance. After performing a Wilcoxon's matched-pairs signed-ranks test on the subjective ratings of 3D visual fatigue, participants were categorized into two groups, unfatigued and fatigued group with a definite criterion. For the unfatigued group, no significant fatigue effects were found in behavioral response times and accuracies to specific auditory targets. In sharply contrast to the unfatigued group, the fatigued group showed significantly delayed response times and less response accuracies. However, no significant changes in accuracies for a working memory task were observed in both groups.

There exist a variety of VR(Virtual Reality) contents that have been developed by the use of the latest VR technologies. Unlike the rapid advances in the recent VR devices however, the development of VR based game contents that fully utilize such cutting-edge devices has been lackluster. Using more accessible form of smartphone-based HMDs(Head-Mounted Displays), we compare two popular VR presentation methods(a realistic 3D VR karaoke room and a 360 degree video karaoke room) and analyze their users' immersion and realistic perception. We expect that our study can be utilized as a supporting guideline for future smartphone-based VR content developments.

최근 각광받고 있는 블로그가 보다 다양한 형태, 즉, 설치형 블로그, 태그기반 블로그, 비디오 블로그 등의 서비스로 발전하고 있다. 반면 모바일 블로그 즉, 모블로그(moblog)는 콘텐츠의 양과 좁은 화면에서의 가독성, 네트?p 사용요금 부담 등의 환경적 제약으로 사용자 저변확대가 이루어지지 않고 있다. 최근 들어 웹 상의 컨텐츠(텍스트, 이미지, 동영상 등)를 모바일 환경에서 효과적으로 표현하기 위한 많은 연구가 진행되고 있지만, 사용자의 불편함은 여전히 존재하고 있다. 본 논문에서는 사용자의 활용성를 높이고, 불편함은 줄일 수 있는 방안으로써 검색에 용이한 `태그`와 사용자 인지가 용이한 `아바타`를 함께 이용하는3D 아바타 기반 블로그 서비스를 제안한다.

Ink painting is an important art creation method in oriental culture. Although ink painting lacks of sense of reality compared to western painting, it contains its unique drawing skills, which is of great significance to the inheritance and development of Oriental culture. Animation or game utilizing by ink painting technique are derivative contents from ink painting. This paper will through research the brief history of 3D ink contents works and traditional drawing skills to research existing ink works' art characters and the general production method. Also describe the extensibility of 3D ink animation contents. There has extremely high research value of new convergence contents as mobile game, VR / AR etc. And according to those research ink style image contents can be assumed get further development in the future.

Game and Animation are considered as two different fields. The definition of animation is 'moving picture' and game is a kind of animation which can be controlled by users. Actually, many principles of animation are applied to the production of games, and are even more emphasized in the mobile game contents which are becoming popular these days because of the characteristics of mobile devices such as small screen size. In this paper, we study on the application of the 12 principles of animation through the making of a mobile 3D game called 'Fly to the music' and that game is going to be serviced in late 2006 by SK Telecom. Moreover, we studied the differences between 3d mobile game animation and ordinary animation.

This study emphasizes the need to understand digital transformation and addresses the development process of functional mobile games with the theme of digital transformation. Through previous research, we found that existing mobile games do not reflect the changes in industries and jobs in the future. In this study, we designed and developed an educational mobile game that can help young people develop digital literacy skills and understand core skills for future changes in industrial structure and jobs due to digital transformation. It utilizes Unity 3D and combines the best features of puzzle, card, and board games. While there may be limitations in terms of expertise in developing educational content, it is important to note that we have presented content that can provide a futuristic view of careers through a game that is highly preferred by students. Considering the direct and indirect educational effects of the game, it is expected to be useful as a vocational education content in the classroom through tablet devices that have recently been distributed in schools.
