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) 在未来的工作、教育和娱乐中发挥核心作用的一个障碍是，许多 VR 用户都会出现晕动症。晕动症的症状与晕动病相似，通常包括恶心、出汗、晕动症等。头晕、头痛和眼睛疲劳会在短短 10 分钟内影响一半以上的 VR 用户，具体取决于 VR 体验的细节。然而，随着时间的推移，人们可以通过反复体验 VR 来减少晕眩症状。例如，容易晕眩的人可以体验 VR 应用程序（例如娱乐应用程序）。让他们在短时间内轻微晕眩，这样他们就可以在不晕眩的情况下体验虚拟现实应用程序（例如，工作培训应用程序），但问题是人们需要适应到什么程度才可能晕眩。这如何因软件而异？该项目使用多天的适应研究来探讨理想情况是否合理以及存在哪些障碍。这项研究研究人类对晕机症的适应，以开发使适应成为减少晕机症的有用工具的技术。了解一个 VR 应用程序中的晕眩适应何时以及在何种程度上会导致不同应用程序中的晕眩适应降低，这种跨应用程序的适应被称为泛化，这将使晕眩适应成为更有用的工具。研究适应的泛化是否取决于在虚拟环境中移动的方法，例如真实行走或使用操纵杆。该研究的另一个目标是了解适应晕眩症是否需要用户最初经历严重的晕眩症，或者是否适应。可以在使用现有技术降低虚拟环境强度的同时最大程度地减少用户的不适感。最后，该研究将检验是否所有个体都能从适应中平等受益，或者人的特征是否会影响适应率，以及适应是否可以普遍适用于 VR 应用程序。 .这些研究目标是核心建立我们关于晕眩适应的知识，并开发现实的技术，帮助 VR 设计师最大限度地减少用户晕眩的不愉快体验，并增加对 VR 技术的使用。该奖项是法定使命，并通过使用基金会的智力评估进行评估，被认为值得支持。优点和更广泛的影响审查标准。
