The aim of this study was to investigate the role of simulated natural sound and light conditions in a virtual garden scene in reducing stress and anxiety. The study was based on a low polygonal virtual garden scene prototyped from the garden of the Swedish organisation Mötesplats Trädgård in Skövde, and combined with four different experimental conditions (birdsong/water flow × warm light during the day/cold light at night). The experiment was divided into two phases, in which participants were required to undergo a stress-inducing period with a scary atmosphere, followed by a free exploration of the virtual garden scene under the assigned sound and light combinations. The study used the State Anxiety Inventory (STAI-S) and the Perceived Stress Scale (PSS) as quantitative measurement tools, together with feedback from the garden experience and semi-structured interviews, to comprehensively analyse the effects of stress and anxiety changes under different combinations of sound and light. The results of the study will provide theoretical support and practical reference for the design and optimisation of natural elements in future virtual nature scenes.
