Truly immersive multimedia experiences also include multisensory components such as factional, tactile etc., in addition to audiovisual stimuli. In this context, this paper reports the results of a user QoE study of an olfaction-enhanced immersive VR environment. The results presented compare the user QoE between two groups (VR vs VR + Olfaction) and consider how the addition of olfaction affected user QoE levels (considering sense of enjoyment, immersion and discomfort). Self-reported measures via post-test questionnaire (10 questions) only revealed one statistically significant difference between the groups; in terms of how users felt with respect to their senses being stimulated. The presence of olfaction in the VR environment did not have a statistically significant effect in terms of user levels of enjoyment, immersion and discomfort.}, doi = {10.1145/3132361.3132363}, isbn13 = {978-1-4503-5507-0}, language = {EN}, pdf = {https://www.itec.aau.at/bib/files/p15-egan.pdf}, talktype = {none}, url = {http://doi.acm.org/10.1145/3132361.3132363} }
