Abstract

The Korean peninsula has been known as an area that is free of volcanic disasters. However, recent observations and research results of volcanoes in Far East Asia, including Baedu Mountain and Japanese volcanoes, show that the Korean peninsula is no longer a safe area from volcanic disasters. Since 2012, the Korean government has been developing an IT-based construction technology, VDRS (Volcanic Disaster Response System), for effective volcanic disaster response system. The main users of VDRS are public officers in central or local governments. However, most of them have little experience and knowledge about volcanic disasters. Therefore, it is essential to develop education contents and implement training on volcanic disaster response for effective response in a real disaster situation. In this paper, we deal with the development of a mobile application based on virtual reality (VR) for realistic volcanic disaster response training. The objectives of training are the delivery of knowledge and experience for volcanic disasters. First, VR contents were generated based on spatial information. A 3D model was constructed based on a Digital Elevation Model (DEM), and visualization models for meterological effects and various volcanic disaster diffusion effects were implemented for the VR contents. Second, the mobile application for the volcanic disaster response training was implemented. A 12-step story board is proposed for volcanic disaster experience. The application was developed with the Unity3D engine based on the proposed story board to deliver knowledge of various volcanic disasters (volcanic ash, pyroclastic flows, volcanic mudflow etc.). The results of this paper will be used for volcanic disaster response and prevention training and for more realistic training linked with augmented reality technology in the future.

한반도는 화산 재해로부터 안전한 지역으로 알려져 왔다. 그러나 최근 백두산 및 일본 화산들을 포함한 극동아시아의 화산 관측동향 및 연구결과들은 더 이상 한반도가 화산 재해로부터 안전한 지역이 아님을 나타내고 있다. 대한민국 정부는 2012년부터 효율적인 화산재해 대응체계 구축을 위해 IT 기반의 화산재해대응시스템(VDRS: Volcanic Disaster Response System)구축기술을 개발해 왔다. VDRS의 주요 사용자는 대한민국 중앙 및 지방정부 공무원들이나 이들 대부분은 화산재해를 경험해 보지 못하였으며, 기본적 지식도 부족하다. 따라서 실제 재난 시, 효과적인 VDRS의 사용 및 재난대응을 위해서는 재해 대응과 관련된 교육 콘텐츠의 개발과 교육의 실시가 매우 중요하다. 본 논문에서는 현실감 있는 화산재해 대응 교육을 위한 가상현실(VR; Virtual Reality) 기반의 모바일 앱 개발을 다루고 있다. 교육의 목적은 화산재해 관련 지식의 전달과 체험이다. 첫째, 공간정보 기반의 VR 콘텐츠를 제작한다. VR 콘텐츠를 제작을 위해서는 수치표고모형 기반 3D 모델이 구축되고, 기상효과 및 다양한 화산재해 확산 가시화 모델이 개발된다. 둘째, 화산재해 대응을 위한 교육앱이 개발된다. 이 단계에서 우리는 12단계의 화산재해 체험 스토리 보드를 제안한다. 앱은 스토리 보드를 기반으로 Unity3D 엔진을 이용하여 개발되며 다양한 화산재해(화산재, 화쇄류, 화산이류 등)를 체험하고 이들에 대한 지식을 전달할 수 있도록 구성된다. 본 연구의 결과는 화산재해 대응 및 예방을 위한 교육에 활용될 수 있을 것이며 향후, 증강현실 기술과 연계한다면 보다 현실감 있는 교육에 활용될 수 있을 것이다.
