In all cases, the reason for discontinuation was the occurrence of simulator sickness in the form of dizziness or nausea.
Other notable usability concerns, such as simulator sickness or visual fatigue (Nichols & Patel, 2002), were also reduced by using non-immersive systems.
being busy with family visitations) and the development of simulator sickness.
Simulator sickness questionnaire: An enhanced method for quantifying simulator sickness.
Following a brief description of the experiment, which included a review of symptoms listed in the Simulator Sickness Questionnaire (SSQ; Kennedy et al.
The results from Experiment 3 supported our hypothesis that simulator sickness may be most readily evoked by visual-vestibular conflicts at the crossover frequency--the frequency at which the summed response from the visual and vestibular self-motion systems is maximum.
Profile analysis of simulator sickness
symptoms: Applications to virtual reality systems.
In addition, recent research suggests that streamlining navigational control may reduce, by nearly half, the level of adverse effects associated with complete navigational control (Stanney & Hash, 1998): 20% or more of the variance in simulator sickness is governed by the kinematics of the visual scene (i.
Uliano, Kennedy, and Lambert (1986) examined delays between 125 and 215 Ins and failed to find a significant effect between increasing time delay and simulator sickness.
Signsim also poses less risk to subjects because they are not on the road and there is little chance of simulator sickness
To assess their initial level of symptoms and to ensure that they were familiar with motion sickness symptoms, participants were asked to complete the simulator sickness
questionnaire, or SSQ (Kennedy, Lane, Berbaum, & Lilienthal, 1993).
Subjects passed a physical examination, drug test, mental-state exam, and cognitive test, as well as a test for simulator sickness
, before being allowed to participate in the study.
For the various Simulator Sickness
Questionnaire scores, navigation speed had a significant influence on only the oculomotor subscore.
Two experiments investigated the effect of conflicting visual-vestibular cues on subjective reports of simulator sickness
during and after a 30-mm exposure to a head-coupled virtual interface.
Participants were permitted to leave the lab only when they appeared to be free of symptoms and ataxia (this determination was not made on the basis of Simulator Sickness
Questionnaire [SSQ] scores; Kennedy & Lane, 1993).
