Simulation using the virtual reality has been applied in various fields such as exercise, education, disaster simulation training, but there is a little research on disease caused by virus transmission. In this study, we conducted simulation studies and analysis of avian influenza disaster response training. The annual avian influenza virus is recurring every year in Korea, but there are still few solutions and preventive measures for the preventing the avian influenza. The avian influenza can cause a great deal of societal harm and enormous economic damage. Prophylaxis is important because livestock epidemics, such as avian influenza and foot-and-mouth disease, have a large impact on farm households. Therefore, we proposed and analyzed contents that can be avoided through simulation of avian influenza disaster response presented in this study.

본 논문에서는 가상현실기반 스토리텔링 시스템을 제작할 때 고려될 일반 사용자를 위한 디자인 방법론을 제안하고자 한다. 최근 가상현실 기술을 이용하여 시각적으로 실감성 높은 콘텐츠를 제작하는 연구에 많은 시도와 진척이 이루어지고 있다. 그러나 시각적 콘텐츠 이상의 의미를 전달하는 방법이나 이를 위한 개인화된 인터페이스에 대한 연구는 아직 미흡한 실정이다. 본 논문에서는 콘텐츠의 개인화된 체험과 그를 위한 인터페이스를 중심으로 스토리를 구성하는 방법을 제안한다. 첫째, 문화재(콘텐츠)에 대한 사용자의 관심도를 고려해 인터랙션(혹은 이벤트) 스토리라인을 구성한다. 둘째, 가상현실기반 프로젝트에 대한 사용자의 경험도를 고려하여 개인화된 인터페이스를 구축한다. 그리하여 사용자가 가상현실기반 스토리텔링을 경험할 때 관심도와 경험도에 맞는 개인별 맞춤 스토리를 경험할 수 있게 하는 것이다. 제안된 스토리텔링 기법은 디지털 에듀테인먼트 시스템에 효과적으로 활용될 것으로 기대된다.

본 논문에서는 개발한 가상현실 게임의 소개와 적용기술에 대하여 서술하였다. 가상현실(Virtual Reality, VR) 게임은 기존의 게임과는 다른 몰입도와 평면을 넘은 가상의 공간, 활동적인 액션의 이점을 가지고 있고 사람들과 같이 활동적인 플레이를 더하기 위해 다중사용자 환경의 기반을 구현하고, 좀 더 활동적인 다중사용자 환경으로 만들기 위해 서로 경쟁하는 사격게임과 같이 협력하여 플레이해 나가는 디펜스게임을 개발하였다. 개발도구로는 에픽 게임스의 언리얼 엔진4 v4.19.2을 개발엔진으로 활용하였고, HTC Vive의 VR장비와 컨트롤러를 사용하여 다중사용자를 위한 VR 게임 콘텐츠를 개발하였다.

This study is about the elderly people's use and experience of Virtual Reality (VR) in order to enhance their quality of life. Leisure is main activity of the elderly. As a result, the quality and diversity of leisure affects the quality of the elderly people's life. VR services including video contents could provide them with advanced and interesting experiences. Across the world, population aging becomes one of the most important problems in each society. The social and economic burden of aging is serious challenge to sustainability welfare of the world, including S. Korea. The authors used virtual reality devices to conduct experiments on 99 aged 50 to 90 (men's average age : 75 and women's average age : 70.8). Through the survey, major variants were measured such as system quality, present sense, enjoyment, intent to reuse, and awareness of advanced technology. Multiple regression analyses with the presence as a dependent variable resulted in a sense of closeness (t = 5.381, p <. 01) and a sense of clarity (t = 4.494, p <. 01). The presence of an independent variant had significant effects on pleasure (t = 4.312, p <. 01) and significant effects on the intent to reuse (t = 3.323,).Therefore, it can be interpreted that the higher the sense of existence, the more pleasure and the intent to reuse it. As a result, the possibility of using VR devices and content to enjoy leisure activities can be found in this study even if the elderly group is unfamiliar with IT devices.

Along with the expectation about 5G network commercialization, interests in realistic and immersive media industries such as virtual reality (VR) are increasing. However, most of studies on VR still focus on video technologies instead of factors for popularity and consumption. Thus, the main objective of this research is to identify meaningful factors, which affect the view counts of VR videos and to provide business implications of the content strategies for VR video creators and service providers. Using a regression analysis with 700 VR videos, this study tries to find major factors that affect the view counts of VR videos. As a result, user assessment factors such as number of likes and sicknesses have a strong influence on the view counts. In addition, the result shows that both general information factors (video length and age) and content characteristic factors (series, one source multi use (OSMU), and category) are all influential factors. The findings suggest that it is necessary to support recommendation and curation based on user assessments for increasing popularity and diffusion of VR video streaming.

Real-time 360 VR (Virtual Reality) stereo image acquisition technique based on game engine was proposed. However, GPU (Graphics Processing Unit) resource is not fully utilized due to bottlenecks. In this paper, we propose an improved GPU scheduling technique to solve the bottleneck of the existing technique and measure the performance of the proposed technique using the sample games of the commercial game engine. As a result, proposed technique showed an improvement of performance up to 70% and usage of GPU resources more evenly compared existing technique.

This study aims to improve the accessibility and efficiency of sign language education for both hearing impaired and non-deaf people. To this end, we developed VR realistic sign language education content that integrates hand tracking technology and conversational AI. Through this content, users can learn sign language in real time and experience direct communication in a virtual environment. As a result of the study, it was confirmed that this integrated approach significantly improves immersion in sign language learning and contributes to lowering the barriers to sign language learning by providing learners with a deeper understanding. This presents a new paradigm for sign language education and shows how technology can change the accessibility and effectiveness of education.
