Efforts to build metaverse platform services and expand profit structure are developing in a more realistic direction. The metaverse, which has been centered on 'creation and economy' and 'discovery', will evolve into an 'experience' metaverse, creating tangible business effects where satisfaction with the user experience leads directly to purchase. In this paper, the condition of the avatar used as a medium of economic activity between the metaverse platformer and the user and the business utilization plan were sought. In addition, a new 'metaverse business model' was proposed based on 'experience, discovery, creation and economy', and in particular, it was intended to lay the foundation for the experience metaverse to further develop in the form of 'business experience'. In addition, a survey was conducted on the 'application of metaverse service and avatar' targeting the MZ generation, the main customer base of the current metaverse service. In order to provide a service that satisfies the user, it was concluded that the appearance of the avatar needs to be changed according to the purpose and function. Accordingly, we propose an 'selective switch mode' that can change the avatar's appearance at the desired timing according to the 'experience' and 'purchase purpose' of each metaverse service area. In addition, by strategically utilizing the 'Digilog' psychology, we believe that it will be possible to promote the influx of new users while increasing the loyalty of existing users to the platform. Through the establishment of 'avatar purchase system' by 'selective switch mode' and 'avatar decorating system' by 'digilog' strategy, the experience metaverse, which has been focused on 'digital twin experience' so far, is As it develops into 'business experience', it is expected that the user experience can be further satisfied.

정보통신기술의 발달로 실감미디어를 활용한 간접 체험 콘텐츠의 수요가 증가하고 있다. 실감미디어는 만들 때 모델들의 전체적인 느낌이 일정하게 유지되어야 콘텐츠를 즐길 때 몰입감을 유지하게 해 준다. 관광지에 대한 간접 체험을 제공하는 실감미디어의 경우 관광지의 실제 정보를 반영한 모델링이 되어야 정확한 체험을 제공할 수 있다. 본 논문에서는 남해안의 대표적인 관광자원인 섬을 실제 데이터를 반영하여 3차원으로 모델링하는 방법을 제안한다. 제안하는 방법에서는 구조화된 절차에 따라 모델링을 하기 때문에 여러 사람이 공동으로 작업하여 콘텐츠를 제작하여도 쉽게 전체 모델의 일관성을 유지하게 해 준다. 우도 섬의 정보를 이용한 모델링 결과를 보면 제안하는 방법이 단순히 높이 정보를 이용한 모델링 방법 보다 사실적인 결과를 만드는 것을 보여준다.

최근 현실감 있는 경험을 제공하기 위한 몰입형 가상현실(VR) 기술에 대한 연구 개발이 활발하게 진행되고 있다. 가상현실 참여자에게 실제와 유사한 실감적인 가상현실 체험을 제공하기 위해서는 실제 현실 공간에 존재하는 환경 및 객체의 정보를 정밀하게 캡처 및 복원하여 가상 환경 시스템의 모델 데이터로 적용한 시스템 구성이 필요하다. 이러한 가상 환경 구성에 필요한 실 데이터를 획득하기 위해서는 다수의 비정형 카메라를 활용한 셋업으로 이루어진다. 하지만, 다수의 비정형 위치의 카메라를 활용해 실제 공간에서의 3차원으로 구성된 정보를 획득할 경우 카메라의 개수 및 위치가 최적화되지 않아 복원의 오류가 발생할 수 있다. 또한, 정밀한 객체 복원을 위해 과도한 양의 비정형 카메라가 배치될 경우 비정형 카메라 배치에 따른 자원의 낭비 또한 발생할 수 있어 적절한 개수의 비정형 카메라가 배치되어야 한다. 본 논문에서는 3차원 공간 데이터를 복원 시 필요한 정보를 얻기 위해 배치되는 다수의 비정형 카메라를 최적화할 수 있는 최적 카메라 배치(Optimal Camera Placement) 학습 기법을 제안한다. 본 논문에서 제안한 방법을 통해 실제 환경 정보 획득 시 정확한 형태의 복원 데이터를 이용하여 가상 환경을 생성하고, 더욱 몰입도 높은 실감형 콘텐츠 시스템을 사용자에게 제공할 수 있다.

This study presents a way to design picture books that allow children to experience indirectly through realistic media at home and educational institutions for children whose direct experiences and activities are reduced offline in the post-COVID-19 era. The development and popularization of realistic media such as AR continues to be grafted and developed in the picture book field, and the advantage of this picture book is that children at the stage before learning letters can feel the story and character situation of the book through the experience of AR and QR animation in the picture book. In this process, you can get access to imaginary areas that can not be experienced in flat-panel illustrations with spatial animation to help improve the scalability and literacy of the story contained on the page. Children's education through realistic animation can increase the learning effect and needs to continue after COVID-19. Therefore, by presenting the process of viewing and experiencing picture books using AR and QR, the result of the study suggests that the design process of realistic picture books is not just a combination of technology, but a process of expanding children's perception and imagination. This study aims to find out how visual perception is designed differently by analyzing the differences and characteristics of each animation design, focusing on the AR and QR picture book "Where am I?" published by the researcher, and to contribute to the active introduction and development of realistic animation in the field of children's picture books and education.

The moving picture experts group (MPEG) immersive video (MIV) technology has been actively developed and standardized to efficiently deliver immersive video to viewers in order for them to experience immersion and realism in various realistic and virtual environments. Such services are provided by MIV technology, which uses multiview videos as input. The pruning process, which is an important component of MIV technology, reduces interview redundancy in multiviews videos. The primary aim of the pruning process is to reduce the amount of data that available video codec must handle. In this study, two approaches are presented to improve the existing pruning algorithm. The first method determines the order in which images are pruned. The amount of overlapping region between the source views is then used to determine the pruning order. The second method considers global region-wise color similarity to minimize matching ambiguity when determining the pruning area. The proposed methods are evaluated under common test condition of MIV, and the results show that incorporating the proposed methods can improve both objective and subjective quality.

In the era of new media, images hold an important position as episteme to express and convey ideas. Fashion films provide dynamic and unique fashion images, differentiated from prior fashion media as a representational tool for showing a realistic fashion image only; consequently, their production and spread are increasing rapidly as a new fashion media. This study identifies the meaning and type of fashion images in fashion films based on the concept of Deleuze's image that help discover distinctive characteristics of fashion films as a new fashion media of an expressive tool. Literature research was conducted on new media, concepts and types of images by Deleuze to analyze types of new media images. According to research, fashion image in fashion film is defined as a fashion event; consequently, three types of new media images are derived. As the result of the empirical study, fashion images in fashion films are classified by images of realistic movement, variable time, and virtual experience. The results of the consideration show that fashion films expressed fashion through temporality and narrative, senses, and diegesis. Fashion images of new media in fashion films portray fashion as a process that transcends reality and imagination.

VR and AR contents provide a rich user experience [1]. Realistic content with human computer interaction and immersion provides an improved user experience, but there is a limit to producing all elements realistically. In this study, we propose a method to advance the rendering of immersive content using background color information [2]. First, the elements necessary for Kelvin temperature rendering are derived from the color and background as context elements, and the rendering effect has been realized in the soap bubble. For soap bubbles Kelvin temperature rendering, the average color of the background is extracted and the color with the highest similarity is applied by comparing the main color and Kelvin temperature.
