“…This effect has been observed in laboratory devices, virtual environments, flight simulators, and console video games [5][6][7][8]. Interestingly, in console video games postural instability and motion sickness are common among individuals who control the game (i.e., players), and occur in games that depict ambulation (i.e., walking or running) rather than vehicular travel [8].…”

“…Earlier studies reported similar increases on postural sway effects of 2D and 3D motion stimuli, however, in separate studies ( [8][9][10][11]42] versus [12], respectively). With this study we were able to compare postural sway caused by viewing 2D and 3D motion stimuli in one single study, and observed that exposure to 3D motion stimuli did not cause more postural sway compared to viewing 2D.…”

“…In addition to VIMS symptoms, viewing motion stimuli can also affect postural control, defined as ''the act of maintaining, achieving or restoring a state of balance during any posture or activity" [7]. In particular it has been shown that postural sway increases due to viewing 2D [8][9][10][11] and 3D motion stimuli [12].…”

Equally moved and not really sick from viewing 2D and 3D motion stimuli on a TV screen

a b s t r a c tObjective: Visually induced motion sickness (VIMS) and increased postural sway are two adverse side effects that may occur when viewing motion stimuli. 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 quantified 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 significant increase to either 2D or 3D exposure. The multi-symptom questionnaire did reveal significant increases in VIMS symptom severity to both 2D and 3D exposure. However, VIMS was not significantly more increased in case of 3D exposure compared to 2D exposure. All postural sway measures (sway path length, standard deviation in mediolateral and anteroposterior direction, as well as the short-range scaling components) increased significantly as a result of exposure. None of the postural sway measures was differentially affected to 3D as compared to 2D exposure. Conclusion: Viewing 3D motion stimuli did not cause more serious VIMS symptoms, compared to viewing motion stimuli in 2D. We attribute this lack of difference to the fact that the 3D effects in this documentary were optimized for viewing in a cinema, the projection on the TV-screen thus causing quarantining of the visual input. The increase in postural sway, irrespective of image type, may reflect exploratory behavior, allowing the participant to gain more information about self-orientation with respect to the virtual environment.

This article describes a new approach in developing computational driver models in vehicle simulations for evaluating intelligent driving support systems (IDSSs). As IDSSs become more intelligent and provide active safety controls, a more comprehensive understanding of a driver's cognitive processes is required as well as vehicle dynamics. One hundred thirty drivers participated in a psychophysical experiment of velocity estimation at 71 checkpoints on a road section. The perceived velocity, as a dependent variable, was modeled using analysis of covariance (ANCOVA) with respect to the driver's fundamental human factors (i.e., age, gender, and driving experience) as independent variables. As a result, eight different perceived velocity models were defined as part of the cognitive processes with quantitative covariates in different modalities (i.e., radius of road, level of interior noise, as well as vehicle velocity). Moreover, driver models implemented with different perceptual processes also exhibited considerable changes in the results of vehicle simulations on double lane change maneuvers. The results presented in this study suggest that defining the perceptual processes of different groups of drivers is an essential process in developing vehicle simulation environments for evaluating IDSS. Consequently, the results from this study may provide meaningful data for early stages of new vehicle design. C 2010 Wiley Periodicals, Inc.
