“…In accordance with our results from a study using a motion platform [36], SCL showed a tendency to increase with motion sickness, although this effect was not significant. Similarly, LaCount et al [38] found SCL to increase with increasing nausea during exposure to horizontally translating stripes.…”

“…However, it has been suggested that the temporal development of HR or mean HR over the entire exposure period does not necessarily reflect the progressive changes in sickness [15,24], thus emphasizing the need for correlational or regression analyses. The mixed regression analysis did show a positive relationship between HR and motion sickness ratings, which confirms previous findings [14,24,36,37].…”

Background: Motion sickness has previously been found to deteriorate performance. In complex working environments, sustained ability to perform despite motion sickness is crucial. This study focuses on effects of motion sickness on encoding and retrieval of words. In addition, the temporal development of psychophysiological responses and their relationship with perceived motion sickness were investigated. Methods:Forty healthy participants (20 male and 20 female, age 19-51) performed an encoding and retrieval task during exposure to an optokinetic drum and were compared with 20 controls (8 male and 12 female, age 21-47) not exposed to motion sickness. Measurements of heart rate, heart rate variability, skin conductance, blood volume pulse, respiration rate, and skin temperature were made throughout optokinetic drum exposure.Results: Moderate levels of motion sickness did not affect the ability to encode or retrieve words. Perceived motion sickness was positively related to heart rate, blood volume pulse and skin temperature and negatively related to respiration rate. Conclusions:The psychophysiological measurements did not show consistent patterns of sympathetic activation and parasympathetic withdrawal, as could be expected. Subjective reports of progressing symptoms are still likely to be the most reliable way of assessing motion sickness.

“…The influence of video-induced motion sickness on the body has been measured by employing subjective scales such as the simulator sickness questionnaire (SSQ) (Kennedy et al, 1993). Further, it is also measured by quantitatively investigating the relationship between external factors and internal conditions using physiological indices such as respiratory functions, electrocardiograms, skin electrical activity, fluctuation of the center of gravity, and electrogastrograms (Holomes and Griffin, 2001;Himi et al, 2004;Yokota et al, 2005). By using the SSQ and stabilometry (body sway), we examined whether the VIMS was induced by a stereoscopic movie in this study.…”

In the present study, we examined the visual accommodation of subjects who were gazing fixedly at stereoscopic images on two different displays: a cathode ray tube (CRT) with the subjects wearing liquid crystal shutter glasses and a liquid crystal display (LCD) with the subjects not wearing liquid crystal shutter glasses. In Experiment 1, we measured accommodation in subjects viewing a moving stereoscopic image. In Experiment 2, we measured accommodation in subjects viewing moving stereoscopic images on an LCD and a CRT. In Experiment 3, we measured accommodation in subjects viewing a stereoscopic image moving from far to near on an LCD. In Experiment 4, we measured of accommodation in subjects viewing moving stereoscopic images (stereoscopic display mode) and non-stereoscopic images (2-D mode) on an LCD.The results suggested, the ciliary muscle is repeatedly strained and relaxed while the subject views the moving target. In the present study, the subjects' accommodative amplitude was changed when the target moved from the near to far point, and vice versa.

“…The SSQ has been used in the present study to verify the occurrence of VIMS. In addition, the following parameters of autonomic nervous activity are considered appropriate for the physiological method: heart rate variability, blood pressure, electrogastrography, and galvanic skin reaction [12][13][14]. It has been reported that a wide stance (with the midlines of the heels from 17 to 30 cm apart) significantly increases the total locus length in the stabilograms of individuals with high SSQ scores, while the length for individuals with low scores is less affected by such a stance [15].…”

Objectives Symptoms of three-dimensional (3D) sickness, such as intoxication and eye fatigue, have been observed in subjects viewing 3D films and vary according to the image quality and visual environment. In addition, the influence of stereoscopic vision on the incidence of 3D sickness has not been explored sufficiently. Therefore, it is important to examine the safety of viewing virtual 3D content. Methods The present study examines the effects of peripheral vision on reported motion sickness during exposure to 2D/3D video clips for 1 min and for 1 min afterwards in human subjects. Stabilograms were recorded during exposure to video clips with or without visual pursuit of a 3D object and compared, and subjects were administered the simulator sickness questionnaire after stabilometry. Results There were no significant main effects of solidity of the visual stimulous (2D/3D) and the vision method (visual pursuit/peripheral viewing) in accordance with the two-way analysis of variance of the sway values, although the sway values during the 2D/3D video clips were higher than in control subjects. A consistent trend in the main effect of stability was observed. Further, the sway values changed remarkably after the 3D video clip was viewed peripherally and produced a persistent instability in equilibrium function. The questionnaire findings also significantly changed after the subjects viewed the video clips peripherally. Conclusions Subjective exacerbation and deterioration of equilibrium function were observed after peripheral viewing of 3D video clips. This persistent influence may result when subjects view a poorly depicted background element peripherally, which generates depth perception that contradicts daily experience.
