Attention mechanisms have been used in deep learning-based computer vision systems, including single image super-resolution (SISR) networks. However, existing SISR networks with attention mechanism focused on real image super-resolution, so it is hard to know whether they are available for CG or VR images. In this paper, we attempt to apply a recent attention module, called balanced attention mechanism (BAM) module, to 12 state-of-the-art SISR networks, and then check whether the BAM module can achieve performance improvement in CG or VR image super-resolution. In our experiments, it has been confirmed that the performance improvement in CG or VR image super-resolution is limited and depends on data characteristics, size, and network type.

The VR(Virtuality Reality) technology provides very close experience to reality by stimulating humans' external recognition with artificial technologies. In order to overcome the limitation of real-environment training, VR is being applied in industry field as a key technology to prevent safety accident and its control procedure training. However, it is difficult to build VR-based training system because 3D modeling and software coding are necessary for materialization of VR environment demands of many development resource. In this research referring to VR based training content implementation, a method to utilizing VRDC(VR-based Dynamic visualization Component) is suggested and by applying it to plant safety training system, it was confirmed its practicality.

Applying VR technology to animation areas is emerging as a trend of recent years. So if you use this VR technology in traditional ink animation, 2D art piece is expected to be equipped with a new narrative style and visual and auditory language, making it a new animation genre. There's a lot of technical difficulties in putting the existing 2D ink image on a 360 degree display. VR ink animation has been created that gives depth to VR space by using layer extraction method based on depth of distance and placing layers extracted on curved surface that is aligned with depth in 360-degree space in the image of ink painting, which is the background of traditional ink animation. In the text, we took an overview on problems generated in extracting layers of distant view, close-range view and middle distant view from the existing image of ink painting and made suggestions of an effective way to approach them.

최근 물리적 언택트(Untact)와 사회적 온택트(Ontact)를 이끄는 기술에 대한 관심이 커지면서 가상현실(VR:Virtual Reality) 기술을 활용한 교육이 주목받고 있다. 이와 더불어 교육 환경이 경험과 체험 위주의 맞춤형 교육으로 급격히 변화함에 따라 사용자 요구를 만족시킬 콘텐츠는 부족한 실태이다. 따라서, 본 논문에서는 효과적인 독서교육을 위해 종이책과 전자책을 비교 설명하며 가상현실 기술을 활용한 동화 체험 시스템을 제안하였다. 사용자 얼굴 3D 텍스처 모델링과 멀티플레이어를 통해 비대면 실감형 콘텐츠와 공공데이터를 활용하여 동화선택 기능을 구현하였다. 이처럼 교육적인 관점에서 스스로 선택한 동화를 함께 체험하고 인지한다는 점에서 효과적이다.

Although the environment in virtual space (hereinafter referred to as VR) has the problem of being difficult to access compared to existing PCs and smartphones, it has the advantage of being more realistic and providing endless experiences and functions compared to existing environments. In this VR environment, there is a need to develop technologies that help people handle tasks more conveniently in the virtual world by studying interfaces and interactions using ChatGPT, a recently popular AI technology. The ChatGPT interface and interaction in the VR environment are also studied to provide personalized services. Through this, users can choose the interface that suits them and the secretary interface can also provide customized services optimized for users. Accordingly, in this study, we design a convenient interaction method by linking the ChatGPT system in a VR environment and use it as a previous study for the development of an AI assistant.

Global virtual reality (VR) and augmented reality (AR) markets are growing as VR and AR become a new source of revenue for industries around the world. In the edutech sector, an industry that combines traditional education, research on new innovative educational models and business models are scarce, and improvements are needed in the technology group and business environment to realize edutech in detail. Therefore, this study aims to define the elements strategically required for VR Toon development by comparing and analyzing the characteristics of existing touch panel-based display Toon and VR Toon content experiences. Tablet PC Toon and VR Toon were selected to conduct the research. Thirty people (19 men and 11 women) from their teens through their forties were surveyed using questionnaires. The questionnaires were formulated through a quantitative method by using AttrakDiff with a 7-point scale (-3: negative words to 3: positive words). Qualitative evaluations were also performed addressing nine concepts (satisfaction, novelty, operability, creativity, understanding, education, interest, participation, expressiveness). As a result, the usability test results of educational content using tablet personal computers and VR equipment were analyzed from the viewpoint of user experience to define elements expected to be strategically required for VR Toon development.

컴퓨터에서 생성된 시뮬레이션의 결과는 컴퓨터 그래픽스 기술을 이용한 일련의 가시화 과정을 거쳐서 인간이 해석하기 쉬운 형태로 변형되게 된다. 최근에는 고성능 컴퓨터(HPC: High Performance Computer)의 발달로 인해 데이터의 크기가 점점 더 증가하는 추세에 있으며, 이런 복잡한 데이터를 해석하는 데는 클러스터 시스템을 이용한 고해상도의 디스플레이 장치가 필요하다. 하지만 이런 디스플레이 장치에서 사용자 인터페이스를 제공하는 방법은 VR(Virtual Reality, 가상현실) 환경을 활용하는 것이 거의 유일한 해결책이다. 하지만 현재 VR 환경에서 시뮬레이션 데이터 해석에 필요한 적절한 사용자 인터페이스를 제공하는 툴은 존재하지 않는다. 이에, 본 논문에서는 시뮬레이터 데이터, 특히 로터 동역학 분야의 시뮬레이션 데이터를 VR 환경에서 가시화하는 GLOVE 프레임워크의 통합 인터페이스를 소개한다. 이 인터페이스는 VR 환경에서 시뮬레이션 데이터를 실시간으로 상호작용을 통해 분석하는 데 필요한 기반 환경을 제공한다.
