Abstract

Virtual reality exposure therapy (VRET) has been used for a several decades. However, we are not aware any studies that used a smart-phone based virtual reality techniques. In this study, we suggested a new smart-phone based VRET that included photorealistic techniques. We also evaluated the current system with 32 healthy participants, and results suggested that the current system evoked different emotional valences in indoor/outdoor and familiar/unfamiliar environments. The meaning of current results and potential applications of VRET were discussed.

사진 기반의 가상 현실 노출 치료 요법(Virtual Reality Exposure Therapy)은 다양한 정신 질환의 평가 및 치료 연구에 사용되어 왔다. 그러나 최근에 보급되기 시작한 스마트폰 기반의 헤드 마운트 디스플레이(Head-mounted display, HMD)를 활용한 가상 현실 노출 치료 연구는 거의 없었다. 본 연구에서는 스마트폰 기반의 가상현실 기기를 활용하여 환경 촬영부터 노출까지 누구나 쉽게 사용할 수 있는 실제 사진 기반의 가상 현실(Photo-realistic VR) 노출 시스템을 제안하고, 32명의 정상군을 대상으로 시험적으로 적용하고자 한다. 본 연구 결과에 따르면 개발된 스마트폰 기반의 시스템은 실내/실외, 친숙한/친숙하지 않은 환경들에서 피험자의 감정 변화를 이끌어내었다. 이에 대한 의의와 모바일 기반의 가상현실 노출 치료 시스템의 장점에 대하여 본 연구에서 논의하였다.
