The objective of this project was to verify whether this effect could be generalised to pleasant odours. Participants were immersed in a virtual apartment with a kitchen where the visual scene suggested that cinnamon apple pies had recently been baked. Participants were randomly and blindly assigned to three conditions: exposition to the ambient air, to a pleasant odour of cinnamon apple pie, or an unpleasant odour of urine. The results indicated that while exposure to the visually concordant pleasant odour did increase the sense of reality in a statistically significant manner, it did not affect the sense of presence or realism. Results also suggested that the visual/olfactory concordance may have facilitated the detection of the pleasant odour. The potential implications of the results, potential explanations for the lack of effect on the sense of presence, as well as potential follow-up research projects are discussed. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.},

This project’s goal was to determine whether the exposure to olfactory stimuli would affect the senses of Presence (primary measure), Reality and Realism (exploratory measures) in VR. In a virtual kitchen devoid of obvious visual cues linking the visual scene to an odour, three groups of 20 randomly assigned participants (12 females and 8 males per group), unaware of the potential exposure to olfactory stimuli, were exposed to either ambient air, a pleasant odour, or an unpleasant odour.
