New Cross-Sensory Approach to Designing Restorative Virtual Environments

Virtual reality (VR) nature immersion is an increasingly popular field of research due to its potential to help people who do not have access to real nature. There are many questions surrounding how virtual forests can be designed to effectively reduce stress and restore attention. Many of these questions relate solely to visual aspects, but more recent literature has started exploring multisensory experiences. In these experiences, senses are treated as additive; however, certain results from the current literature may indicate that there are more complex, cross-sensory interactions occurring. For example, adding sound to visuals can increase stress reduction potential, but certain natural sounds can feel threatening if they are out of place within the virtual nature scene. Overall, cross-sensory interactions in VR nature environments (VNEs) are underexplored and challenge our current understanding of multisensory VNEs, and future explorations of these interactions are essential for designing optimal VNEs for stress reduction.
