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.

晕眩症（即由虚拟现实等沉浸式模拟引起的晕动病）对健康用户的影响多年来一直是虚拟现实（VR）的基础研究领域之一，但其对身体残疾人士的影响仍然存在未知，尽管它可能会对这一人群基于 VR 的身体康复产生重大影响。该项目调查残疾人的晕机症，特别是患有中度行动障碍且无认知障碍的多发性硬化症患者。这项研究的预期成果是最大限度地减少晕机对残疾人的负面影响，从而显着提高基于 VR 的身体康复效果和运动障碍人士的生活质量。该项目的第一个目标是确定衡量残疾人晕机症的最佳方法，其次是找出导致残疾人晕机症的主要因素，特别是存在本体感觉和平衡缺陷的人（例如，由于神经、前庭、平衡问题）。根据初步数据，中心假设是，由于平衡和本体感觉能力的差异，与正常人相比，残疾人因 VR 引起的网络晕眩症会更大。为了检验这一假设，该项目将 (a) 确定残疾与 VR 引起的网络晕眩症之间的关系，(b) 确定针对残疾人士 VR 引起的网络晕眩症的最有效的客观衡量标准，(c) 确定 VR 的主要贡献方面影响残疾人晕机症的设计，并 (d) 创建、传播和维护残疾人士晕机症数据的开放数据库。 更广泛的影响：该项目将朝着应对以下挑战迈出关键一步： VR 的普遍可用性，让人们更深入地了解 VR 作为康复媒介的有效性。该项目将影响残疾人进行基于 VR 的康复和锻炼的方式，这可能会对康复的有效性和功效产生长期影响，并最终影响这些人的生活质量。该项目将积极吸引研究生和本科生参与研究，将研究成果整合到关于无障碍用户界面和通用可用性的新颖课程中，并与国家残疾人倡导协会合作，促进基于 VR 的康复教育和激励。
