However, whether these effects are elevated to a greater extent when viewing stereoscopic 3D motion stimuli, compared to 2D stimuli on a TV screen, has not been investigated under controlled circumstances. Therefore this study aimed at investigating VIMS and postural sway before, during, and directly after viewing 2D and 3D motion stimuli, on a commonly available TV screen. Method: 16 Participants were exposed to an aviation documentary shown in 2D and in 3D on separate occasions. Before, during, and after exposure, VIMS and postural sway were measured. VIMS was quanti?ed by a rating scale giving a single number, and by a multi-symptom questionnaire that assessed multiple VIMS symptoms separately. Sway path length, standard deviations and short-range and longrange scaling components of the center of pressure were calculated as measures of postural sway. Results: VIMS symptom severity, as obtained with the single rating scale, did not show a signi?cant increase to either 2D or 3D exposure. The multi-symptom questionnaire did reveal signi?cant increases in VIMS symptom severity to both 2D and 3D exposure. However, VIMS was not signi?cantly more i
