The effects of cybersickness (i.e., motion sickness caused by immersive simulation, such as virtual reality) on healthy users has been one of the fundamental research areas in virtual reality (VR) for many years, but its impact on persons with physical disabilities is still unknown, even though it could have a significant an impact on VR-based physical rehabilitation for this population. This project investigates cybersickness for persons with disabilities, specifically for persons with multiple sclerosis with a moderate level of mobility impairment and no cognitive impairment. The expected outcome of this research is to minimize the negative effects of cybersickness for people with disabilities, and to thereby significantly improve the effectiveness of VR-based physical rehabilitation and the quality of life for people with motor impairments.The first objective of this project is to determine the best way to measure cybersickness in people with disabilities, and the second is to then figure out the main factors that contribute to cybersickness in persons with disabilities, specifically for people with proprioceptive and balance deficits (e.g., due to neurological, vestibular, balance issues). Based on preliminary data, the central hypothesis is that VR-induced cybersickness will be magnified for persons with disabilities as compared to persons without disabilities because of differences in balance and proprioception abilities. To test this hypothesis, the project will (a) determine how disability correlates with VR-induced cybersickness, (b) determine the most effective objective measures of VR-induced cybersickness for people with disabilities, (c) determine the main contributing aspects of VR design that affect cybersickness in people with disabilities and (d) create, disseminate, and maintain an open database of (anonymized) cybersickness data from people with disabilities.Broader Impacts: The project will take a critical step towards the challenge of universal usability in VR and offer a deeper understanding of the effectiveness of VR as a medium for rehabilitation. The project will impact the way that people with disabilities are able to engage in VR-based rehabilitation and exercises, which could potentially have long term impact on the effectiveness and efficacy of the rehabilitation and ultimately the quality of life for these people. The project will actively engage graduate and undergraduate students in research, integrate results from research into a novel course on accessible user interfaces and universal usability, and collaborate with national advocacy societies for persons with disabilities to promote education and motivation for VR-based rehabilitation.

Cyber​​sickness（即，由沉浸式模拟引起的运动疾病，例如虚拟现实引起的运动疾病）对健康使用者的影响一直是虚拟现实中的基本研究领域之一（VR）多年来，但它对身体残疾人的影响仍然未知，即使它对基于VR的身体对该人群的恢复产生重大影响。该项目调查了针对残疾人的Cyber​​sickness，特别是针对具有适度流动性障碍且没有认知障碍的多发性硬化症患者。这项研究的预期结果是最大程度地减少网络智能对残疾人的负面影响，从而显着提高基于VR的身体康复和运动障碍者的生活质量的有效性。该项目的第一个目标是确定与残障人士相处的最佳方法，以及在残疾人中衡量的人，以及在残疾人方面的特殊因素，以使其在残疾人方面贡献cy的人，从而贡献了cy的人，从而贡献了cy的人，以使其在残疾人中造成了贡献，从而贡献了cy的人，以使其在残疾人中造成贡献，从而贡献了cy的人，以促进cy的人的贡献。本体感受和平衡缺陷（例如，由于神经系统，前庭，平衡问题）。基于初步数据，中心假设是，由于平衡和本体感受能力的差异，与没有残疾的人相比，残疾人的VR诱导的Cyber​​sickness将被放大。要检验该假设，该项目将（a）确定残疾与VR诱导的网络智能的相关性，（b）确定对残疾人的VR诱导的网络智能的最有效的客观度量，（（c）确定VR设计的主要促进性的主要促成方面，这些方面从残障人士中影响了Cyber​​sickness，并在残障人士中创建了cy and（D），并（d）and（d）and（d）and（d），（d）and（d），（d）and（d），（d）and nequalsike cy（d）残障人士的影响：该项目将迈出关键的一步，朝着VR中普遍可用性的挑战迈出了重要的一步，并对VR作为康复媒介的有效性有了更深入的了解。该项目将影响残疾人能够从事基于VR的康复和锻炼的方式，这可能会对康复的有效性和有效性产生长期影响，并最终对这些人的生活质量产生影响。该项目将积极吸引研究生和本科生研究，将研究的结果整合到有关可访问用户界面和普遍可用性的新课程中，并与国家倡导社会合作，为残疾人促进教育和基于VR的康复动机的动力。
