Objective: In our study, we investigate the effects of eco-therapy in virtual reality (VR) for different demographic groups. Background: Evolution-honed connection to nature is essential for psychological well-being, and eco-therapy has been pronounced as a cure for hypertension, obesity, depression, stress and other pressing health issues. Though studies consistently find higher life satisfaction in city dwellers who have access to green areas, today’s barriers to enjoyment of real nature are many: surging rent in greener districts, increasing pace of life, expensive or time-consuming commuting, etc. Lately, virtual eco-therapy that implies engagement with 2D or 3D nature-themed digital content is gaining in popularity, but its neurophysiologic effects remain largely unexplored. Moreover, cognitive and even physical discomforts have been reported for certain user groups interacting with VR/AR, such as inexperienced or elder people. Method: We performed experimental study with 23 subjects of different ages who experienced urban and natural surroundings in VR headsets (Oculus Rift S) and on a computer monitor (2D). We surveyed their psychometric data (emotional state and environmental identity) and registered brainwave activity with 64-channel electroencephalography (EEG). Results: Natural stimuli caused higher Valence (positive emotions) and decreased EEG power in the frequency bands associated with stress and neurological disorders. VR immersion surged Arousal and Dominance components of the emotional status, as well as attention-related EEG power. The environmental identity index had an unexpected effect in young males, intensifying stress and task-solving in the “virtual forest”. Conclusion: Our findings include: 1) positive effect of natural stimuli on the psycho-emotional status, 2) age-, gender-, and personality-dependent impacts of nature-related digital content and 3) considerable impact of the VR immersion itself. Application: We believe that our results might be of interest to digital content and interaction designers, as well as to VR/AR developers, who seek to make the technologies more universally accessible and beneficial.
