Quantitative and physiological evaluation of three dimensional images

To find a new physiological index for quantitative evaluation of the effects of visual, stimuli on the human blood pressure and heart rate of 33 subjects watching two or three dimensional video image were analyzed. The experiments have shown that the maximum crosscorrelation coefficient ρ_max from blood pressure to heart rate, whose frequency components were limited to the neighborhood of 0.1Hz, could well reflect the human emotional reaction to visual stimuli. It has also significantly been shown that three dimensional display yielded smaller ρ_max than two dimensional one and that the subjects who previously reported their proneness to motion sickness had smaller ρ _max than those who did not
