Fig. 3From: Towards perceptual accuracy in 3D visualizations of illuminated indoor environmentsBaseline MOS. Ten separate plots are shown, each showing the mean opinion scores (MOS) over all 28 observers versus lighting condition for each perceptual attribute in the real-room baseline experiment, shown with 95 % confidence intervals. Shaded regions indicate condition categories: warm (conditions 1–4), cool (5–8), dimmed (9–12), and spots (13–15)Back to article page
