Console video games, postural activity, and motion sickness during passive restraint.

Area of Science:

• Human physiology
• Vestibular system research
• Human-computer interaction

Background:

• Motion sickness is a common issue in virtual environments.
• Active control of visual stimuli can influence sickness severity.
• The role of passive restraint on postural activity and sickness is not fully understood.

Purpose of the Study:

• To investigate the effect of passive restraint on postural activity and motion sickness.
• To determine if active control mitigates sickness under restraint.
• To identify postural activity patterns associated with motion sickness.

Main Methods:

• Twenty-four adults were passively restrained using elastic bands while playing a driving video game for 50 minutes.
• Head and torso movements were recorded using a magnetic tracking system.
• Participants completed the Simulator Sickness Questionnaire and a yes/no sickness report.

Main Results:

• Five participants (20.83%) reported motion sickness.
• Despite passive restraint, participants exhibited measurable head and torso movements.
• Movement magnitude and temporal dynamics differed significantly between sick and well groups.

Conclusions:

• Passive restraint can reduce motion sickness when participants actively control the nauseogenic visual stimulus.
• Distinct postural activity patterns precede motion sickness, even during passive restraint.
• This study highlights the interplay between body restraint, active control, and sensory-motor responses in motion sickness.
