Subjects were 12 men and 12 women (age 23.2±SD 2.4 years) who were likely to get motion sickness. Audio-visual stimulus experiment was conducted to induce motion sickness symptoms. Five intensities of stimuli were loaded at the order of weak to heavy. Subject put on a face-mounted display device to gaze at driving simulation images.
