Use of an independent visual background to alleviate simulator sickness in the virtual environments that employ wide-field displays

摘要: Simulator sickness (or so-called Cybersickness) has been a significant problem since the development of virtual reality systems. Numerous studies have investigated this problem. However, there is currently no accepted solution. This dissertation addresses possible approach to alleviate simulator sickness. Prior work suggested method inserting an inertially-matched reference visual background grid into scene as intervention against sickness, but little done evaluate or optimize such method. describes series human factors examine and “independent background” (IVB). Four major components are included. The first part provides regarding second examines dynamics sensory conflict theory which widely model In regard we identified verified motion frequency where summed response from inertial self-motion systems was greatest. We also effects field-of-view display. third explores characteristics IVB including spatial, polarity, temporal stereographic properties As means determining subjects' reactions moving stimuli, postural stability, measured. Postural stability proposed objective measurement for fourth ways that may reduce symptoms during environment exposure. consider relationship between sense presence conclude could be useful procedure recommend future experiments how should presented enhance users' task performance cognitive function.
