  • In this paper, we propose sharing 3D media between multisite using enhanced Access Grid (e-AG) which is a composition of 3D display and Access Grld (AG) Conventional AG and other collaborative systems have a limitation to share immersive 3D media Thus, proposed system supports sharing 3D media contents in a AG meeting section. Real object can be shared by acquiring stereo image with pre-calibrated stereo camera and by delivering, and virtual object can be shared by transmitting state information after downloading 3D model. And also, real video scene acquired by stereo camera and virtual object from 3D model can be displayed on the 3D display system of each node adaptively. The characteristics of proposed sharing method are sharing 3D media, displaying 3D media on a system adaptively, supporting real-time interaction. The proposed sharing method will be used remote lecture, remote collaboration with 3D media.

  • Recently, as the development of 3D contents service, production of 4D media that user can feel physical effects by the scene of movie has been increased. This 4D media uses the SMMD (Single Media Multiple Devices) method to give users enhanced effects with multiple devices playing rather than the SMSD (Single Media Single Device) method with single device playing in a smart TV environment. To give more sensible effects to users, from the beginning of making one media, we produced 4D media that consists of 3D contents and the SEM (Sensory Effect Metadata) to define effects of the scene. 4D media is transmitted to a HS (Home Server) to represent 3D contents in 3DTV and multiple devices with synchronized way. In this paper, we suggested the concept and overall 4D media broadcasting service system architecture, aggregator time acquisition, media time scheduling, real-sense device scheduling, evaluation results, user interfaces and implemented devices.

  • 본 논문은 기존의 2D 전자 동화책과는 달리 유아들에게 보다 창의적이고, 극적표현력을 길러줄 수 있도록 오프라인의 출판 원작동화의 내용과 그림을 안드로이드 기반으로 3D 입체 기술을 접목시킨 인터렉티브 에듀테인먼트로 3D 입체 전자동화를 개발한다. 즉, 동화의 줄거리에 따라 살아 움직이는 장면을 인터렉티브 애니메이션 뿐 만 아니라 좀 더 생생하게 동화를 체험할 수 있는 인터렉티브 3D 입체 전자 동화를 개발한다.

  • Despite skepticism about commercial potential, the stereoscopic 3D cinema is still a form that any filmmaker can choose to employ for its aesthetics and its immersive potential. Based on a haptic illusion, the stereoscopic media content requires a new perspective different from the principle of 2D media content in terms of creation and acceptance. This paper examines the technical and aesthetic issues of stereoscopic 3D film production from the perspective of today's emerging realistic and immersive media through a case study. One of the key factors for successful content creation and research and development in stereoscopic 3D cinema is the combination of artistic principles together with technical mastering of the new image technology. The purpose of this paper is to outline the principal challenges and research topics in stereoscopic 3D cinema through a case study of stereoscopic 3D pilot film production for the 'User-Selective UHD Stereoscopic Media Service Platform' of the ETRI (Electronics and Telecommunications Research Institute). This paper intends to examine stereoscopic 3D filmmaking workflow and production methodologies, as well as technical elements and aesthetic issues.

  • There are several researches on 2D gaze tracking techniques to the 2D screen for the Human-Computer Interaction. However, the researches for the gaze-based interaction to the stereo images or 3D contents are not reported. This paper presents a gaze-based 3D interaction technique on autostereoscopic display system.

  • Deep learning has made rapid progress in recent years and is affecting various fields and industries. The art field cannot be an exception, and in this paper, we would like to explore and experiment and analyze research fields that creatively generate 2D images in 3D from a visual arts and engineering perspective. To this end, the original image of the domestic artist is learned through GAN or Diffusion Models, and then converted into 3D using 3D conversion software and deep learning. And we compare the results with prior algorithms. After that, we will analyze the problems and improvements of 2D to 3D creative generation.

  • 본 논문에서는 3D 프린터의 다양한 활용분야를 소개한다. 3D 프린터의 원래의 목적은 상품을 내놓기 전 시제품을 만들기 위해서였으나 최근 들어 그 활용분야가 공업, 의료, 실생활 분야로 넓혀지고 있다. 공업 분야에서는 한 장씩 레이어를 쌓아가는 3D 프린터의 장점을 이용해 보다 정밀하고 세밀한 공정이 가능해 진다. 이러한 특성은 기존의 방식보다 진행시간을 5~10배 이상 단축시켜 제품개발에 소요되는 비용과 노력을 절감하는 뛰어난 효율성을 보여준다. 의료분야에서는 3D모형물을 그대로 제작할 수 있기 때문에 인간의 신체와 보다 흡사한 보형물을 만들 수 있다. 나아가 3D프린터가 상용화 된다면 판매사가 제공하는 3D 콘텐츠를 사용자가 쉽게 이해하고 이에 따른 피드백을 받아 빠르게 제품생산에 이용할 수 있어 상품에 대한 만족도를 높일 수 있게 된다.

  • Generally, if we want to change the perspectivity of objects, we should change the position of object or camera, forward or backward. In this paper, recognition of the perspectivity of objects is proposed by using a new elemental image array which is made change the pinhole points horizontally.
