Abstract

Currently, virtual reality contents using VR images are spotlighted since they can be easily created and utilized. But because VR images are in a state of lack of interaction, there are limitations in their applications and usability.In order to overcome this problem, we propose a new method in which 360 degree panorama image and game engine are utilized to develop a high resolution of interactive VR service in real time. In particular, since the background image, which is represented by a form of panorama image, is pre-generated through a heavy rendering computation, it can be used to provide a immersive VR service with a relatively small amount of computation in run time on a low performance device. In order to show the effectiveness of our proposed method, an interactive game of a virtual zoo environment was implemented and illustrated showing that it can improve user interaction and immersion experience in a pretty good way.

VR 영상을 활용한 가상현실 콘텐츠는 제작의 용이성과 사용자 편의성으로 인해 주목받고 있으나 상호작용이 결여된 상태이기 때문에 응용 분야와 활용성에 있어서 한계가 있다. 본 연구에서는 이러한 문제점을 극복하고자 360도 파노라마 영상과 게임엔진을 활용하여 상호작용이 가능한 고해상도 VR 서비스를 구축하는 방안을 제시한다. 특히 복잡한 연산이 소요되는 배경 영상은 파노라마 영상으로 미리 렌더링하여 생성한 것이므로 낮은 사양의 단말기에서도 높은 프레임 수를 유지하면서 서비스를 제공할 수 있는 특징이 있으며, 사용자의 시점과 움직임에 반응하여 고해상도의 배경영상을 발췌하여 보여주기 때문에 상당한 몰입감을 구현할 수 있다. 본 제안 방법의 효과성을 보이기 위해 가상 동물원 환경을 VR로 구성하여 보았으며 사용자의 상호작용과 몰입감을 증대시킬 수 있음을 보이기 위해 상호작용 게임을 사례로 보인다.
