Abstract. This study explored the effects of combining virtual reality (VR) and biofeedback on the restorativeness of the created experience as judged by the user and the user’s sense of presence. In a between-subjects experiment, we disentangled the effects of display type (VR vs. computer screen) and biofeedback (electrodermal activity biofeedback vs. no biofeedback) in the context of immersive simulated relaxation environments. After a stress induction, 94 healthy participants were randomly assigned to one of four relaxing treatments. There were no treatment-specific differences in subjective stress or physiological arousal. However, VR compared with computer screen increased the sense of presence and, partly, perceived restorativeness. When combined with VR, biofeedback increased physical presence and, in part, perceived restorativeness. The study offers insight that allows for the identification of future research avenues.
