Recent technological advances have led to a profound increase the quality of multimedia content, in addition todifferent ways in interacting with and consuming it. Technologies such as Virtual Reality (VR), 360-degree video,Augmented Reality (AR) and 3D audio aim to support novel immersive and interactive experiences. However, suchapproaches towards immersion only stimulate two of the five human senses. Opportunities now exist to target thehuman senses outside the traditional audio and visual, to include tactile, olfaction, and gustatory. Hence, it is possibleto develop applications that consider inputs across all senses, i.e., truly immersive and interactive multimediaexperiences. Such experiences may be influenced by the integration of different media formats, sensory modalities,the context, the user and varying communication/delivery mechanisms; with the aim to increase the perceptual userand quality of experience. Indeed such experiences are only possible by a multidisciplinary research approach whichinvolves (and is not limited to) multimedia, psychology (including experimental), human-computer interaction, socialcomputing and electronics among many others. In addition, the range of applications for virtual reality, augmentedreality, 360-degree video and multisensory experiences is quite diverse with related and unique research challenges.Such domains include tele-presence, training/education, health, tourism, entertainment etc. Critical to the success ofthese immersive and multisensory experiences (IMEx), is the fact that on a per application basis, it is crucial tounderstand the perceptual user and the quality of experience (QoE).
