Screenshots of some of the environments in Psyrreal shown in sequence to exemplify the diversity of visuals presented to the user during the experience. The experience starts in a temple (top left), progresses through different levels of varying abstraction and intensity, and culminates in outer space (bottom right). See also Supplementary material 1 for more illustrations of the environments and Table 1 for more detailed descriptions of the implemented concepts. CEV stands for “closed-eye visuals.”
