Design and Implementation of a Low-Cost Arduino-Based Walking Interface for Immersive Virtual Reality Environments

Jonghyun Kim

본 연구는 가상현실(VR) 콘텐츠에서 사용자의 몰입도를 향상시키기 위한 아두이노 기반의 저비용 보행 인터페이스를 제안한다. 본 인터페이스는 걷기, 뛰기, 절름발이와 같은 다양한 사용자의 보행 동작을 감지하고 이를 가상 환경 내 캐릭터 움직임에 반영함으로써 사용자 몰입감을 증대시킨다. 이를 위해 아두이노(Arduino) 기반의 센서 장치를 개발하여 …

Large Étendue 3D Holographic Display with Content-adaptive Dynamic Fourier Modulation

B. T. Chao, Manu Gopakumar, Suyeon Choi, Jonghyun Kim et autres

Emerging holographic display technology offers unique capabilities for next-eneration virtual reality systems. Current holographic near-eye displays, however, only support a small etendue, which results in a direct tradeoff between achievable field of view and eyebox size. Etendue expansion has recently been explored, …
