In this report, the following conclusions can be drawn after our experiment identified the state of subjects' physiological responses by selecting those exhibiting any VR sickness symptom from 115 general subjects and showing them walkthrough-composed images. (1) The comparison of a value of VR sickness observed and types of displayed images found that the extent of VR sickness is largely determined by distance from the presented image and the passage time of the VR experiences, and that the value of VR sickness observed increases with the passage time. (2) The comparison of types of displayed images found that the sickness by the image is not necessarily caused by stereoscopic vision, in addition to image quality. (3) As for the consideration of the weariness, visual weariness and VR sickness show a high correlation, and when a VR sickness symptom is observed, the rate of visual weariness indicates a relative increase. (4) While the discussion on physiological responses show that a short-time VR experience does not affect the autonomic nervous function, it is suggested that a three-dimensional vision displayed on the screen generates a state of tension, causing subjects VR sickness, according to the analysis of time-series behavior of the heart rate.
