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"
