Exploring the Effects of Physiologically Triggered Visual Adaptations on XR Experience

This study investigates the effects of dynamic and static visual manipulations, specifically darkening vignettes, on user experience and task performance in extended reality (XR) environments. By using heart rate (HR) as physiological feedback, the study explores how dynamic visual adaptations based on HR impact immersion, task focus, and user comfort. A user study (n = 16) found that while dynamic vignettes could increase immersion and encourage a more focused approach, they also induced discomfort, anxiety, and reduced task performance for some participants. The results reveal that although users may adapt to these visual effects over time, the variability in emotional and physical reactions suggests that such dynamic visual adaptations based on physiological signals should be carefully calibrated to balance enhanced immersion with user comfort. This research contributes to the understanding of adaptive XR environments and the role of physiological feedback in shaping user experience.
