One barrier to virtual reality (VR) playing a central role in the future of work, education, and entertainment is the fact that many VR users experience cybersickness. Symptoms of cybersickness are similar to those of motion sickness, and often include nausea, sweating, dizziness, headache, and eyestrain. Cybersickness can affect more than half of VR users within just 10 minutes of exposure, depending on details of the VR experience. Such a high rate of cybersickness will limit the accessibility of VR and its many applications, especially for the most susceptible people. However, people can adapt through repeated experiences with VR to reduce cybersickness symptoms over time. For instance, a person who is susceptible to cybersickness could experience a VR application (for example, an entertainment application) that gently exposes them to cybersickness over a short period of time so that they can later experience VR applications (for example, a job training application) without sickness. But questions remain. How much adaptation is needed? How sick do people have to be before they adapt? How does this vary by software application or by person? This project uses multi-day adaptation studies to explore whether the ideal scenario is plausible and what roadblocks exist. This research studies human adaptation to cybersickness to develop techniques that will make adaptation a useful tool to reduce cybersickness. One goal is to learn when and to what extent cybersickness adaptation in one VR application will lead to lower cybersickness in a different application. This carryover of adaptation across applications is referred to as generalization, and it would make cybersickness adaptation a more useful tool. The research will investigate whether generalization of adaptation depends on the method used to move through the virtual environment, such as real walking or using a joystick. Another goal of the research is to learn whether adaptation to cybersickness requires the user to initially experience substantial cybersickness, or whether adaptation can occur while minimizing the user’s discomfort using existing techniques for reducing the intensity of virtual environments. Finally, the research will examine whether all individuals equally benefit from adaptation, or whether characteristics of the person affect the rate of adaptation and whether adaptation generalizes across VR applications. These research goals are central to building our knowledge about cybersickness adaptation as well as developing realistic techniques that will help VR designers minimize the unpleasant experience of cybersickness for users and increase access to VR technology.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

虚拟现实（VR）的一个障碍在工作，教育和娱乐的未来中发挥了核心作用，这是许多VR使用者体验Cyber​​sickness的事实。 Cyber​​sickness的症状类似于运动疾病的症状，通常包括恶心，出汗，头晕，标头和眼睛疲劳。 Cyber​​sickness在接触10分钟内会影响超过一半的VR用户，具体取决于VR体验的详细信息。如此高的网络智能率将限制VR及其许多应用的可访问性，尤其是对于最易感人士而言。但是，人们可以通过反复的VR体验来适应随着时间的流逝而减少Cyber​​sickness症状。例如，一个容易受到Cyber​​sickness的人可以体验VR应用程序（例如，娱乐应用程序），该应用程序在短时间内轻轻地将其暴露于Cyber​​sickness，以便以后可以在没有疾病的情况下体验VR应用程序（例如，职业培训申请）。但是问题仍然存在。需要多少适应？人们适应之前必须有多么生病？这与软件应用程序或人员有何不同？该项目使用多日适应研究来探索理想场景是否合理以及存在哪些障碍。这项研究研究了人类对Cyber​​sickness的适应性，以开发将适应成为减少Cyber​​sickness的有用工具。一个目标是了解一个VR应用中的Cyber​​sickness适应性在何种程度上会导致在其他应用中降低Cyber​​sickness。跨应用程序的适应性结转称为概括，这将使Cyber​​sickness适应性成为更有用的工具。该研究将研究适应的概括是否取决于用于穿越虚拟环境的方法，例如实际行走或使用操纵杆。该研究的另一个目标是了解适应网络智能是否要求用户最初体验大量的Cyber​​sickness，或者在使用现有技术减少虚拟环境强度的现有技术中最小化用户的不适时会进行适应。最后，研究将检查所有个人是否从适应中相等的好处，还是人的特征是否会影响适应率以及适应性是否在VR应用中概括。这些研究目标是建立我们对Cyber​​sickness适应的知识以及开发现实的技术的核心，这些技术将有助于VR设计师最大程度地减少Cyber​​sickness的不愉快的Cyber​​sickness的不愉快体验，并增加对VR技术的访问权限。该奖项反映了NSF的法定任务，并通过使用该基金会的知识分子优点和广泛的影响来评估NSF的法定任务。
