초록

최근 VR 환경은 모바일학습, 스마트 공장을 포함한 다양한 분야에서 활용되고 있으나 개별 HMD(head-mounted display) 연계를 위한 고가 및 고사양의 전용운영 시스템이 요구된다. 또한 VR 시스템 설계 시에서는 기술적 고려사항인 가상체험공간에서의 이동성(mobility), 이용자 편의성(usability) 및 실감영상 제공을 위한 성능(performance)에 대한 문제해결이 필요하다. 많은 VR 응용은 스트리밍 기반으로 다양한 센서 및 지속적으로 사용자 입력을 다루어야 한다. 본 논문에서는 무선으로 콘텐츠를 제공받는 저가의 모바일 VR HMD 구성 및 이를 활용한 VR 모바일 플랫폼을설계한다. 제작된 HMD 는 실시간의 가속도계와 자이로 센서로부터 사용자의 움직임에 따른 회전각을 검출한다. 이를 위해 6 축 센서인 MPU-6050 의 활용하여 유니티 게임 엔진상의 VR 렌더링 서버에서 생성된 3D 이미지 렌더링를 처리하도록 개발한다.

Recently VR environment is used in many areas including mobile learning, smart factory. However HMD(head-mounted display) is required to a dedicated and expensive system with high-end specification. When designing a VR system, it is needed to handle performance, mobility and usability. Many VR applications need to handle diverse sensors and user inputs continuously in a streaming manner. In this paper we design a VR mobile platform and implement a low-cost mobile VR HMD running on the platform. The VR HMD supports 3D contents delivery in a mobile manner. It is used to detect the motion detection based on angle value of a VR player from accelerator and gyro sensor. The MPU-6050, 6-axis sensor, is used to get a sensory value and the sensory value is taken as an input to a VR rendering server on a Unity game engine that is generated 3D images.
