Motion Sickness Rehabilitation for Virtual Reality

Overcoming Motion Sickness in Immersive Virtual Reality

The objective of this study was to investigate the effect of a rehabilitation program on motion sickness. A combined rehabilitation program will be given participants who showed motion sickness symptoms.

In the realm of virtual environments and simulators, a significant hurdle that hampers user engagement resides in the manifestation of adverse effects. These deleterious consequences become apparent during prolonged exposure to virtual settings, with approximately 30% of users grappling with symptoms like nausea and up to 40% reporting eyestrain. Furthermore, users frequently describe a constellation of other discomforting sensations, including headaches, dizziness or vertigo, compromised postural stability, drowsiness, increased salivation, and perspiration. These adverse effects have been documented in scientific literature under various monikers, with 'cybersickness' and 'motion sickness' (MS) being the most prevalent designations.

Motion sickness, a vexing symptom characterized by discomfort experienced during movements unrelated to one's bodily motions, such as those encountered during travel by air, sea, or land, lies at the crux of this issue. The pathophysiological elucidation of the mechanisms underlying MS centers around the notion of sensory conflict or sensory mismatch. This conflict arises from disparities between the sensory information derived from kinaesthetic inputs, the vestibular and visual systems, and the sensory patterns engendered by the virtual environment
