Abstract

This study applied virtual reality systems for forest therapy to reduce motion sickness and enhance immersion using multi-sensory elements. In applying virtual reality systems, multi-sensory elements were utilized to reduce motion sickness while providing a more immersive experience. Among these elements, tactile and olfactory devices utilizing wind and scent were developed and employed. The program was developed using Unity3D's HDRP (High Definition Render Pipeline), and both HMD (Head Mounted Display) and non-HMD systems were established to determine if visual motion induces motion sickness. An air circulator was placed to provide a sense of wind and allow users to smell scents through the olfactory device. An experiment was designed to examine whether tactile and olfactory stimuli influence user satisfaction with the virtual reality forest therapy system. The results showed that the tactile device significantly reduced motion sickness, while the developed olfactory device did not yield significant results in reducing motion sickness for participants.

본 연구는 산림치유를 위해 가상현실 시스템을 적용하여 멀미를 줄이고, 몰입감을 높이기 위해 다감각 요소를 사용하였다. 가상현실 시스템을 적용하는 데 있어 멀미를 줄이는 수단으로 다감각적 요소를 사용하면서 더욱 몰입감 있는 경험을 제공하려 한다. 이를 위해 바람과 향기를 이용한 촉각과 후각 장치를 개발하여 사용하였다. Unity3D의 HDRP(High Definition Render Pipeline)을 사용하여 프로그램을 개발했고, HMD(Head Mounted Display)시스템과 non-HMD(non-Head Mounted Display)시스템을 구축하여 시각적 움직임으로 멀미를 유발하는지 확인하였다. 향기를 맡을 수 있게 후각 장치와 바람을 맞는 듯한 촉각을 주기 위해 에어서큘레이터(Air circulator)를 배치하였고 이를 통해 후각과 촉각이 가상현실 산림치유 시스템에 대한 만족도에 영향을 끼치는지 확인하기 위해 실험을 설계하였다. 실험결과 촉각 장치는 멀미를 줄이는 것에 유의미한 결과를 얻었으나, 개발된 후각 장치가 피험자에게 멀미를 줄이는 것에 대한 유의미한 결과를 얻지 못하였다.
