Enhancing User Experience in VR using Wearable Olfactory System

This paper introduces a mounted olfactory device prototype that instantly emits and quickly switches scents. Earlier approaches, such as fixed olfactory devices, have limitations in terms of the time it took for users to perceive a scent in Virtual Reality (VR) due to dissipating lingering scents in physical space, as well as the lack of instantaneous scent switching. To evaluate its effectiveness, we conducted a pilot user study comparing mounted and fixed olfactory devices.The results show that the mounted olfactory device provides a better VR experience than the fixed olfactory device.
