We simulated videogame scenes in simplified 3D computer graphics and evaluated the discomfort from the images by altering the simulation parameters. In the evaluation, the subjects viewed the images including oscillating motion and rotating motion with or without a fixation object. The subjective symptoms on the discomfort of image, degree of motion sickness, sense of eye movement and body movement were assessed by a 5 point rating questionnaire. Besides, the eye movements during viewing the stimuli were measured by using video camera. We found a significant relationship between the discomfort of the images and the sense of eye movement under the condition of oscillating motion. Moreover, the eye movements were reduced by adding the fixation object into the images.
