Area of Science:

  • Human-Computer Interaction
  • Neuroscience
  • Biomechanics

Background:

  • Virtual environments can induce motion sickness and postural disequilibrium.
  • Persistent postural disequilibrium post-exposure poses safety risks and potential liability concerns.
  • Current assessment methods may not adequately certify user balance upon exiting VR systems.

Purpose of the Study:

  • To develop and validate a portable, automated system for assessing postural stability.
  • To establish objective criteria for certifying user balance after virtual reality (VR) exposure.
  • To ensure user safety by verifying balance recovery before leaving a VR environment.

Main Methods:

  • Development of a portable, automated postural assessment system.
  • Utilizing normative and validation experiments to identify reliable measures of stance.

Related Experiment Videos

  • Implementing a novel video-based head movement analysis for objective postural stability measurement.

    • Main Results:

    • Identified reliable stance measures for postural equilibrium certification.
    • Demonstrated the stability and reliability of a new automated video-based head movement measure.
    • Showed predictable and significant head movement changes with stimuli like alcohol and simulator exposure.

    Conclusions:

    • The proposed automated system and objective measures can certify user balance post-VR exposure.
    • Integrating objective postural stability measures with symptom self-reports enhances VR safety certification.
    • This approach can help mitigate risks associated with VR-induced postural disequilibrium.
