Simulator Sickness Questionnaire

Cybersickness continues to become a negative consequence that degrades the interface for users of virtual worlds created for Virtual Reality (VR) users. There are various abnormalities that might cause quantifiable changes in body awareness when donning an Head Mounted Display (HMD) in a Virtual Environment (VE). VR headsets do provide VE that matches the actual world and allows users to have a range of experiences. Motion sickness and simulation sickness performance gives self-report assessments of cybersickness with VEs. In this study a simulator sickness questionnaire is being used to measure the aftereffects of the virtual environment. This research aims to answer if Immersive VR induce cybersickness and impact equilibrium coordination. The present research is formed as a cross-sectional observational analysis. According to the selection criteria, a total of 40 subjects would be recruited from AVBRH, Sawangi Meghe for the research. With intervention being used the experiment lasted 6 months. Simulator sickness questionnaire is used to evaluate the after-effects of a virtual environment. It holds a single period for measuring motion sickness and evaluation of equilibrium tests were done twice at exit and after 10 mins. Virtual reality being used in video games is still in its development. Integrating gameplay action into the VR experience will necessitate a significant amount of study and development. The study has evaluated if Immersive VR induce cybersickness and impact equilibrium coordination. To measure cybersickness, numerous scales have been developed. The essence of cybersickness has been revealed owing to work on motion sickness in a simulated system.

Rotational Dynamic

As virtual environment (VE) technology has become more disseminated, harmful physiological influences on users of VE have been reported such as simulator sickness and motion sickness – collectively called VE sickness. For VE safety and comfort, we note a new dynamic visual illusion, called ""rotational dynamic illusion"". Several psychophysical experiments measuring head movement in illusion observation suggest that perceptive features of rotational dynamic illusion are closely related to balance, which causes VE sickness. These features will be effective in realizing VE safety and comfort and trigger advances in VE technology development.

The Impact

Virtual reality (VR) users are frequently limited by motion sickness-like symptoms. One factor that might influence sickness in VR is the level of control one has in a virtual environment. Reason's Sensory Conflict Theory suggested that motion sickness occurs when incompatibilities exist between four sensory inputs. It is possible that control and sensory compatibility are positively related. If this is the case, increasing control in a virtual environment should result in decreasing symptomology. To test this, the present study used the Simulator Sickness Questionnaire to measure symptomology of 163 participants after exposure to a virtual environment. Three levels of control and compatibility were assessed. It was hypothesized that the participants with control and compatible sensory information would experience fewer symptoms than participants in either the control/incompatible or no control/incompatible conditions. Although significant main effects were found for both gender and condition, the findings were opposite of those hypothesized. Possible explanations for this finding are discussed.

Questionnaire Score

There are substantial individual differences in susceptibility to motion sickness, yet little is known about what mediates these differences. Spatial ability and sex have been suggested as possible factors in this relationship. 89 participants (57 women) were administered a Motion Sickness Questionnaire that assesses motion sickness susceptibility, a Water-level Task that gauges sensitivity to gravitational upright, and a mental Rotation Task that tests an individual's awareness of how objects typically move in space. Significant sex differences were observed in performance of both the Water-level Task ( p<.01), and the Mental Rotation Task ( p<.005), with women performing less accurately than men. Women also had significantly higher scores on the Motion Sickness Questionnaire ( p<.005) Among men, but not women, significant negative relationships were observed between Water-level Task performance and Motion Sickness Questionnaire score ( p<.001) and between Mental Rotation Task performance and Motion Sickness Questionnaire score ( p<.005). In conclusion, women performed significantly more poorly than men did on the spatial ability tasks and reported significantly more bouts of motion sickness. In audition, men showed a significant negative relationship between spatial ability and motion sickness susceptibility.

AbstractBackground:Virtual environments in medical education are becoming increasingly popular as a learning tool. However, there is a large amount of evidence linking these systems to adverse effects that mimic motion sickness. It is also proposed that the efficacy of such systems is affected by how well they engage the user, which is often referred to as presence.Purpose:This primary purpose of this study was to look at the side effects experienced and presence in the Virtual Environment for Radiotherapy Training (VERT) system which has recently been introduced.Method:A pre-VERT questionnaire was given to 84 subjects to ascertain general health of the subjects. The simulator sickness questionnaire was utilised to determine the side effects experienced, whereas the igroup presence questionnaire was used to measure presence. Both questionnaires were given immediately after use of the VERT system.Results:The majority of symptoms were minor; the two most commonly reported symptoms relating to ocular issues. No relationship was seen between simulator sickness and presence although subjects with a higher susceptibility to travel sickness had reported higher levels of disorientation and nausea. There was also a decrease in involvement with the system in subjects with a higher susceptibility to travel sickness.

Flight simulators are examples of virtual environment (VE) systems that often give rise to a form of discomfort resembling classical motion sickness. The major difference between simulator sickness and other forms of motion sickness is that the former exhibits more oculomotor-related symptoms and far less actual vomiting. VEs of the future are likely to include more compellingly realistic visual display systems, and these systems can also be expected to produce adverse symptoms. The implications of simulator sickness for future uses of VEs include adverse consequences for users' safety and health, user acceptance, training effectiveness, and overall system performance. Based on data from a factor analysis of over 1000 Navy and Marine Corps pilot simulation exposures, a new scoring procedure for simulator sickness has recently been developed (Lane & Kennedy, 1988; Kennedy, Lane, Berbaum, & Lilienthal, 1992). The factor analytic scoring key provides subscales for oculomotor stress (eyestrain), nausea, and disorientation. Simulators are being examined in terms of these factor profiles to identify causes of simulator sickness. This approach could also be used in evaluating motion sickness-like symptomatology that occurs in connection with the use of VEs. This paper describes the use of the multifactor scoring of the Simulator Sickness Questionnaire (SSQ) in diagnosing sources of simulator sickness in individual simulators. Reanalysis by this new methodology was employed to standardize existing simulator sickness survey data and to determine whether relationships existed that were missed by the more traditional scoring approaches.
