Abstract

This paper introduces a system to reproduce the olfactory effect using the MPEG-V (ISO / IEC 23005) standard to verify the reliability of the fragrance used in the olfactory experiment Using the implemented system, with experiment participant wearing HMD(Head Mounted Display), we carried out one-to-one matching of aroma and scent object images, matching images of aroma and many scent objects, matching of aroma and fragrance object images, and analyzing distance preference. The results of the experiment showed that aroma of coffee, cocoa, banana, and peach aroma is suitable scent for testing. In case of coffee aroma with high matching accuracy, 10 ~ 20cm distance between smell and participant was more effective in image matching than 30cm. In the future, we can conduct the olfactory research for enhancing the sense of immersion and presence of virtual reality contents using the selected fragrance.

본 논문은 후각실험에 사용되는 향기에 대한 신뢰성을 검증하기 위한 연구로 MPEG-V(ISO/IEC 23005) 표준을 활용한 후각효과 재현 시스템을 소개한다. 구현된 시스템을 활용하여 실험 참여자들에게 두부장착교시장치(Head Mounted Display: HMD)를 착용시킨 상태에서 향기와 향기객체 이미지의 일대일 매칭, 향기와 다수의 향기객체 이미지 매칭, 그리고 발향장치와 피험자와의 거리별 선호도 분석을 실시하였다. 실험 결과 분석을 통해 후각도구로 커피, 코코아, 바나나, 복숭아 향기를 실험에 적합한 향기로 선정하였다. 매칭 정확도가 높았던 커피 향기의 경우 발향장치와 참여자 사이의 거리가 10~20cm인 경우가 30cm보다 이미지 매칭에 더 효과적이었다. 향후 본 연구를 통해서 선정된 향기를 사용하여, 가상현실 콘텐츠의 몰입감 및 현장감 향상을 위한 후각 연구를 진행할 것이다.
