Common stereoscopic three-dimensional (3D) display has a convergence and accommodation conflict that violates the natural human cognitive process of viewing. This weakness exposes the challenge in supporting fun factors while eliminating safety problems in the 3D viewing experience. Thus, human factors have become a major research topic. In this letter, we propose a 3D stereoscopic visualization platform that can expand the sense of a 3D space by fusing organically mixed stereoscopic displays to provide a continuous feeling of 3D depth. In addition, we present pilot test results to show the possibility of the technical implementation of the proposed platform and note ongoing research issues to be addressed.

공장 내 생산설비 배치나 건물 내 인테리어 디자인에서, 생산성 및 전체 디자인을 손상하지 않고 장비들을 신규 도입 혹은 재배치하는 것은 고비용의 작업이다. 이러한 실제 물체들을 가상공간에서 배치 시뮬레이션 하기 위한 방법으로 본 논문에서는 혼합현실 기반의 인터페이스를 제안한다. 제안된 인터페이스는 공장 내 생산설비 배치를 위한 시뮬레이션 알고리즘이 적용되었다. 제안된 인터페이스의 하드웨어는 이동식의 PC 플랫폼위에 사용자 입력을 위한 터치스크린과 비디오카메라가 장착되어 영상을 실시간적으로 보여주는 디스플레이(video see-through display) 를 사용한다. 가상물체와 실제물체가 정교히 합성된 혼합 현실 영상에서 터치 입력을 통해 가상 물체들을 회전 및 이동을 통해 재배치한다. 구현된 인터페이스를 통해, 우리는 제안된 인터페이스가 공간 배치 응용 분야에서 유용성이 있음을 확인하였다.

In this study, safety education contents for medical radiation workers were produced based on Mixed Reality(MR). Currently, safety training for radiation workers is based on theory. This is insufficient in terms of worker satisfaction and efficiency. To address this, we created ICT(Information and Communication Technologies)-based MR radiation worker safety education content. The expected effect of Mixed Reality worker safety education content is that education is possible without space and time constraints, realistic education is possible without on-site training, and interaction between images is possible through reality-based 3D images, enabling self-directed learning Is that. In addition, learning in a virtual space expressed through HMD(Head Mounted Display) is expected to make education more enjoyable and increase concentration, thereby increasing the efficiency of education. A quantitative evaluation was conducted by an accredited institution and a qualitative evaluation was performed on users, which received excellent evaluation. The MR safety education conducted in this study is expected to be of great help to the education of medical radiation workers, and is expected to develop into a new educational paradigm as online education in accordance with Corona 19 progresses.
