360 product photography is one of the realistic media technologies that can observe subjects from various angles as one of the real-world VR production methods. This study examined the effect of 360 product photography on the intention to Continuous Use through the technology acceptance model. The results of the online survey showed that informative, which is the characteristic of 360 product photography, affects both ease of use and perceived usefulness, while reliability and entertainingness affect only perceived usefulness. Internal innovation had an impact on perceived ease, but not on perceived usability. Ease of use, both mediators, had a positive effect on sustained use intention. These findings can be used as a reference for various studies in the field of 360 product photography which is still insufficient. In addition, it can provide strategic implications for the production direction of 360 product photos.

Crowd behavioral scenes in virtual underwater world are presented in many entertainments such as films and games. According to the increase of digital films and animations caused by the development of computer graphics, it is easy for us to meet with the cyber characters in those scenes. Characters which appear in computer animation put life into virtual world. The more characters we have in this virtual space, the deeper we are immersed in the space. There were many researches which processed the crowd scene and implemented the crowd behavior system in Korea. They were related to developing VR contents which were available to feel actually in the construction of the virtual environment. But they are far from reaching the step to put to practical use in developing the crowd behavior modeler. Therefore, we suggestion the fish schooling behavior modeler that provides interaction and action behavior in 3D object to present vividly and effectively in underwater world.

The esthetics of 'grotesque' and its entertaining values have many things in common with the characteristics and properties of animation as a medium of expression. The ways to express grotesque images in animation have expanded its realm of expression with the development of modern image digitalization technologies. The grotesque images that were expressed by the combination of photographs and animations and objet animations have been developing its disharmony in a more realistic manner with full 3D animation technology and realistic motions of virtual characters with motion capture. The subject matter also has become more diverse with the advance of modern scientific civilization. An example is the appearance of Cyborg(cybernetic+organism) characters and the grotesque images in the modern times mainly start to appear in animations dealing with the isolation of human beings among its characteristics. Also, the changes of the expression methods of grotesque images along with the development of visual technology development in the future will transform its methodological forms by changing its expression methods to VR forms and interactive visuals. Thus it is expected that the grotesque images and characteristics will change into a visual genre which emphasizes dehumanization.

In order to increase the practical usability of the virtual reality(VR)-based BIM object in the construction site, the difference between the virtual image and the real image should be resolved, and when it is applied to the construction schedule management function, it is necessary to reduce the image gap between the virtual completion and the actual completion. In this study, in order to solve this problem, a prototype of 4D model is developed in which augmented reality (AR) and 3D printing technologies are linked, and the practical usability of a 4D model linked with two technologies is verified. When a schedule simulation is implemented by combining a three-dimensional output and an AR object, it is possible to provide more intuitive information as a tangible image-based schedule information when compared to a simple VR-based 4D model. In this study, a methodology and system development of an AR implementation system in which subsequent activities are simulated in 4D model using markers on 3D printing outputs are attempted.

Micro light-emitting diodes (LEDs), with a chip size of 100 micrometers or less, have attracted significant attention in flexible displays, augmented reality/virtual reality (AR/VR), and bio-medical applications as next-generation light sources due to their outstanding electrical, optical, and mechanical performance. In the realm of bio-medical devices, it is crucial to transfer tiny micro LED chips onto desired flexible substrates with low precision errors, high speed, and high yield for practical applications on various parts of the human body, including someone's face and organs. This paper aims to introduce a fabrication process for flexible micro LED devices and propose micro LED transfer techniques for cosmetic and medical applications. Flexible micro LED technology holds promise for treating skin disorders, cancers, and neurological diseases.

In the real estate industry, the latest changes in the Fourth Industrial Revolution, such as big data analytics, machine learning, and VR (virtual reality), combine to bring about industry change. Proptech is a new term combining properties and technology. This study aims to derive and analyze from a comprehensive perspective the quality factors (systems, services, interfaces, information) for mobile real estate brokerage services that are well known and used in the domestic market. The surveys in this study were conducted online and offline and a total of 161 samples were used for statistical analysis. As a result, all hypotheses were approved to except system quality and service quality. The results show that the domestic proptech companies who are mostly focused on real estate brokerage services, peer-to-peer lending, advertising platforms and apartments need to grow in various fields of proptech business of other countries including Europe, USA and China.

최근에 TV 방송에서 가상스튜디오나 가상캐릭터와 같은 가상현실(VR:Vinual Reality) 기술이 자주 사용되고 있으며, 증강현실(Ah: Augmented Reality) 기술에 대한 관심도 높아지고 있다. 본 논문에서는 증강현실 기술을 방송에 응용한 가상스크린 시스템에 대해 소개한다. 가상스크린 시스템은 움직이는 색상패턴 패널을 추적하여 실시간으로 그 위에 동영상을 합성하는 증강 영상 시스템이다. KBS 기술연구소에서는 가상스크린 시스템을 개발하고 'K-비전'이라 이름지었다. 이 시스템은 사용자가 들고 움직이는 패널에 동영상이나 그래픽 영상 등을 보여줄 수 있는데, 보여지는 모든 영상은 카메라의 움직임과 패널의 움직임에 따라 정확하게 입혀진다. 패널 추적을 위하여 블럽분석(blob analysis)이나 특징추적(feature tracking)과 같은 영상처리 기술을 이용한다. K-비전은 모든 타입의 카메라와 사용 가능하며, 특별한 부가장치가 필요하지 않다. 센서를 부착하지 않아도 되고, 캘리브레이션(calibration) 과정 또한 필요하지 않다. K-비전은 선거개표방송, 다큐멘터리, 오락 프로그램 등 생방송 프로그램에서 활용한다.

역사적으로 전염병은 기존의 경제 질서를 완전히 바꾸는 촉매제였다. 전문가들은 코로나19가 디지털 플랫폼 경제를 획기적으로 확대하고 보호주의 중심의 글로벌 경제 질서를 획기적으로 재편할 것으로 내다봤다. 특히, 비대면 문화가 보편화됨에 따라 기존 산업에서 인공지능으로 이어지는 혁신 기술을 접목한 디지털 기반 산업으로 전환해야 할 필요성에 따라 ICT 기반 기업 간의 경쟁이 심화될 것으로 예상된다. 코로나19는 신기술로 막 뛰어든 스타트업 ICT 기업에게 새로운 기회가 될 수도 있고, 기존 ICT 기업이 입지를 강화해 글로벌기업으로 거듭날 수 있는 기회가 될 수도 있다. 그 기회의 중심에는 4차 산업 혁명을 이끌 인공지능 기술이 있다. 본 고에서는 포스트 코로나 시대를 위한 인공지능 기술의 동향과 발전 방향을 살펴보고, AR 및 VR과 같은 영상 미디어 기술의 역할에 대해서 살펴본다.

현대 영상산업에서 컴퓨터 그래픽스가 차지하는 비중은 크게 늘어나고 있다. 컴퓨터 그래픽스 기술의 발달로 인한 디지털 영화나 애니메이션이 점차 증가함에 따라 이러한 장면이 등장하는 가상캐릭터를 쉽게 접할 수 있다. 이런 가상 캐릭터를 이용하여 가상 해저 환경을 생성하기 위해서는 3D 모델링 및 애니메이션 기술을 개발해야 한다. 국내에서는 가상 해저 환경을 구축하여 실감 체험을 할 수 있는 VR 콘텐츠 기술 개발에 관련하여 군중 장면 처리 및 군중 행동 시스템의 설계 및 구현 등의 연구가 있었으나 군중 행동 모델러 기술 개발을 실용화 할 단계까지는 미치지 못하고 있다. 본 논문에서는 가상 해저환경에 존재하는 다수의 캐릭터의 움직임을 수작업으로 제공하는 것이 시간과 비용이 많이 소요되기 때문에 이를 자동화하여 보다 사실적이고 효율적인 가상 해저환경 속에서 군중 행동 장면을 생성하기 위해서 Fish 군중 행동 모델러 기술을 개발한다.
