Effects of Image Realism on the Stress Response in Virtual Reality
summary
A virtual ICU is built with no sound and four visual-realism levels and tested in a within-subjects lab study with four visual-realism levels and 19 participants. Objective sensors record heart rate, breathing, GSR, IPQ, PSQ20 and show significant differences from baseline and between conditions, but subjective questionnaires are noisy and inconclusive. Results claim image-realism changes physiological stress, unexpectedly with some abstract scenes producing higher stress than the most realistic, and the real-ICU comparison remains unresolved.
