Visually induced illusory self-motion perception is named “Vection”. The application of vection in VR environments, amusement parks and movies has been increased significantly. We conducted three studies about it. First, to know the ordinary people's knowledge of vection, we conducted a questionnaire to 2147 persons and revealed some aspects who know vection and who do not know it. The characteristics of people who know vection are, more men than women, more annual income, and more knowledge of IT and Psychology. There is no significant difference in age, life satisfaction, self-evaluation and daily audio-visual time and in their occupation. Second, we investigated the effect of the Auto-stereo visual display, i.e. Looking Glass, comparing to the common non-stereo TV display. We set up three conditions, 2D and 3D Looking Glass and 2D TV. Two speeds of optic flow were employed. The results showed that the small auto-stereoscopic display device could induce strong vection like a large TV display. Third, a virtual movie theater was created in the university and examined whether the different positions in the theater could induce vection differently. The results showed that participants could perceive the strongest vection in the center of the front row. In the case of the same screen distance, the left or right position has little effect. The heights of the participants did not change the intensity of the vection. Previous studies have extensively examined the stimulus parameters for effective vection induction. Our three studies could be thought as the application research of vection and created a new trend in vection.
