Multimodal Feedback Methods for Advancing the Accessibility of Immersive Virtual Reality for People With Balance
Abstract:
Maintaining balance in immersive virtual reality (VR) environments poses a significant challenge for users, particularly affecting those with pre-existing balance disorders. This study investigates the efficacy of multimodal feedback-comprising auditory, vibrotactile, and visual stimuli-in mitigating balance issues within VR. A sample of 68 participants, divided equally between individuals with balance deficits related to multiple sclerosis and those without, was evaluated. The research explored the impact of various feedback conditions on balance performance. The results demonstrated that the multimodal feedback condition significantly enhanced balance control compared to other conditions, with statistical analysis confirming this improvement (p<.001). These findings underscore the potential of integrated sensory feedback in addressing balance-related difficulties in VR, thereby improving the overall accessibility and user experience for individuals affected by balance impairments. This research contributes valuable insights into optimizing VR environments for enhanced stability and user comfort.
