Purpose: The purpose of the study was to investigate the effects of HMD (head mounted display)-based virtual reality balance training on static balance in young adults, and whether appropriate balance training can help healthy adults to improve balance ability in daily living. Methods: The study sub...

가상 현실이란? | 가상 현실은(virtual reality)은 특정 작업의 수행에 있어서 주변 환경과 상호 작용하며 가상 환경을 실제 공간으로 인식할 수 있도록 만들어주는 3차원적 정보처리 방법을 의미한다(Liu et al., 2019; Moreno et al. | |
기본적인 가상현실 프로그램은 어떤 환경을 사용하여 대상자에게 제공되는가? | , 2020). 기본적인 가상현실 프로그램은 영상 출력을 위한 모니터 혹은 다중 프로젝트 환경을 사용하여 사실적인 영상과 소리 등의 복합적 감각을 가상으로 생성하여 대상자에게 제공한다(Liu et al., 2019; Moreno et al. | |
가상현실에서 사용되는 영상 장치의 종류 중 HMD는 무엇인가? | HMD는 헬멧 형태의 장치를 머리에 착용하는 장치이며 전면에 단일(monocular HMD) 혹은 두 쌍(binocular HMD)의 광학 영상 장치가 사용된다(Munsamy et al., 2020; Saredakis et al., 2020). 일반적으로 HMD 장비에는 관성 측정장비(inertial measurement unit)가 결합되어 있으며 이를 통해 머리의 움직임을 동시적으로 측정할 수 있다(Lee at al, 2018). VR 전용 컨트롤러와 베이스 스테이션은 대상자의 움직임을 측정하며 가상 현실에서의 공간 영역을 설정하는데 사용된다. HMD 시스템을 활용한 가상 재활 훈련의 장점은 대상자에게 넓은 시야각을 제공하고 움직임에 대한 추적 및 시각화를 통해 높은 몰입감을 만들어 특정 작업 수행에 대한 집중력을 높일 수 있다는 것이다(Lee at al, 2018; Munsamy et al., 2020; Saredakis et al. |
