Abstract

@@We examined effects of three-dimensional image with head mounted display (HMD) on heart rate (HR) and skin blood flow (SkBF) that measured by laser Doppler technique. Ten healthy volunteers participated in two experimental conditions while they watched three-dimensional image with head mounted display (3D condition) of they watched two-dimentional image (2D condition). The subject rested for 3minutes with HMD and then watched 2D (or 3D) image for 15minutes. Comparing HR during 2D condition with that during 3D condition, there was no difference between both conditions. However, in both conditions, HR decreased as soon as the image was shown (pƒ0.01). The change of SkBF during 3D condition tended to increase with experiment time, whereas that during 2D condition tended to decrease with experiment time, which was evidenced by a significant interaction effect condition by time (pƒ0.05).
