국립부경대-日야마나시대 연구팀, AR 환경 시각·후각 상호작용이 감정 반응에 미치는 영향 규명

증강현실 환경에서 시각과 후각이 동시에 자극될 때, 각 감각의 상호작용이 사용자의 감정 반응에 영향을 미치는 것으로 나타났다.

국립부경대학교 인공지능융합학과 진예지 박사과정생과 장원두 교수, 일본 야마나시대학교 샤오양 마오(Xiaoyang Mao) 교수와 마사키 오마타(Masaki Omata) 교수 연구팀은 증강현실(AR) 환경에서 시각 입자 효과와 후각 자극의 상호작용이 사용자의 감정 반응에 미치는 영향을 EEG(뇌파)와 설문을 통해 분석했다. 

연구 결과, 입자의 색상과 이동 방향은 후각 정보로 유발된 감정에 영향을 줬으며, 특히 향과 일치하는 색상의 입자가 후각 자극과 함께 제시될 때 긍정적인 감정이 강화되는 경향이 나타났다. 

반면 대부분의 시각 효과는 EEG 기반 감정 분류 정확도를 낮춰 후각에 의해 형성된 감정 신호를 복잡하게 만드는 것으로 확인됐다. 그러나 향과 일치하는 색상의 입자가 뒤쪽으로 이동하는 조건에서는 후각 단독 조건과 유사한 수준의 감정 분류 정확도가 유지돼, 시각·후각 정보의 적절한 조합이 감정 인식에 긍정적으로 작용할 수 있음을 확인했다.

이번 연구는 향기와 시각 효과를 결합한 AR 환경에서 사용자의 감정 반응과 뇌파 변화를 분석했다는 점에서 의의가 있다. 향후 향기와 시각 자극을 적절히 조합함으로써 AR 환경에서 사용자의 몰입감과 감정 경험을 조절할 수 있으며, 스트레스 완화, 심리 안정, 치료 보조 시스템, 몰입형 엔터테인먼트, 감성 인터페이스 설계 등에 활용될 수 있을 것으로 기대된다.

이 연구 성과를 담은 논문 ‘The Effects of Visual-Olfactory Interactions with Moving Particles on EEG-based Emotional Classification in AR Environments’는 시각화, 컴퓨터 그래픽스, 가상·증강현실, 사용자 인터페이스 분야의 세계적 국제학술지 "IEEE Transactions on Visualization and Computer Graphics"(JCR 상위 6%)에 이달 게재됐다.<부경투데이>

Pukyong National University-University of Yamanashi Research Team Identifies the Effects of Visual-Olfactory Interactions in Augmented Reality Environments on Emotional Responses

- Findings Expected to Advance Immersive Entertainment and Affective Interface Technologies

 

When visual and olfactory stimuli are presented simultaneously in an augmented reality (AR) environment, the interaction between the two sensory modalities has been found to influence users’ emotional responses.

 

A research team comprising doctoral student Ye-Ji Jin and Professor Won-Doo Jang of the Department of Artificial Intelligence Convergence at Pukyong National University, together with Professor Xiaoyang Mao and Professor Masaki Omata of the University of Yamanashi, Japan, investigated how the interaction between visual particle effects and olfactory stimuli in an AR environment affects users’ emotional responses. The team analyzed these effects using electroencephalography (EEG) and questionnaire-based assessments.

 

The results showed that the color and movement direction of particles influenced emotions induced by olfactory information. In particular, positive emotions tended to be enhanced when particles in colors matching the scent were presented together with olfactory stimuli.

 

In contrast, most visual effects were found to lower the accuracy of EEG-based emotion classification, making the emotional signals formed by olfactory stimuli more complex. However, when particles in colors matching the scent moved backward, emotion classification accuracy remained at a level similar to that observed under the olfactory-only condition. This confirmed that an appropriate combination of visual and olfactory information can have a positive effect on emotion recognition.

 

The study is significant in that it analyzed users’ emotional responses and EEG changes in an augmented reality (AR) environment combining olfactory and visual stimuli. The findings suggest that appropriately integrating scent with visual effects could help regulate users’ immersion and emotional experiences in AR environments. The technology is expected to have applications in stress reduction, psychological well-being, therapeutic support systems, immersive entertainment, and affective interface design.

 

The research findings were published this month in the paper “The Effects of Visual?Olfactory Interactions with Moving Particles on EEG-based Emotional Classification in AR Environments” in "IEEE Transactions on Visualization and Computer Graphics", virtual and augmented reality, and user interfaces, ranked in the top 6% (JCR).
