Urinary catecholamine release and pH of saliva was measured to detect the fatigue induced by application of the virtual reality (VR) used as a human interface of the Hyper Hospital-a network based virtual reality mediated medical care system. After the usage of the VR for 30 minutes, none of three types of catecholamines (Epinephrine, Norepinephrine, and Dopamine) nor pH of saliva increased significantly. It was therefore concluded that fatigue by the 30 minutes loading of the VR is not detectable in terms of the urinary catecholamine release and of pH of saliva.
