| contents | Incorporating multi-sensory cues into Virtual Reality (VR) can significantly enhance user experiences, mirroring the multi-sensory interactions we encounter in the real-world. Olfaction plays a crucial role in shaping impressions when engaging with others. This study examines how non-verbal cues from virtual agents-specifically olfactory cues, emotional expressions, and gender-influence user perceptions during encounters with virtual agents. Our findings indicate that in unscented, woodsy, and floral scent conditions, participants primarily relied on visually observable cues to form their impressions of virtual agents. Positive emotional expressions, conveyed through facial expressions and gestures, contributed to more favorable impressions, with this effect being stronger for the female agent than the male agent. However, in the unpleasant scent condition, participants consistently formed negative impressions, which overpowered the influence of emotional expressions and gender, suggesting that aversive olfactory stimuli can detrimentally impact user perceptions. Our results emphasize the importance of carefully selecting olfactory stimuli when designing immersive and engaging VR interactions. Finally, we present our findings and outline future research directions for effectively integrating olfactory cues into virtual agents. |
