Virtual Reality (VR) technologies have become more affordable and accessible to a diverse population in recent years. One of the biggest challenges for VR users is virtual reality sickness, also known as cybersickness, in which users experience symptoms including eyestrain, headache, sweating, fullness of head, disorientation, vertigo, and nausea. Although factors that cause cybersickness, and ways to reduce it, have been studied for many years in adults, children are increasingly frequent VR users whose rapid psychological development may affect both the mechanisms by which they experience cybersickness and the type and severity of the symptoms. This project will investigate these possible differences between children and adults through creating effective measures of cybersickness for children and comparing the severity and drivers of cybersickness between adults and children. Achieving these objectives will allow the team to develop guidelines for developing safe VR content for children that will expand the population of children who are able to benefit from VR experiences. This research is among the first to investigate cybersickness in children thoroughly. The causes of cybersickness are still debatable, and how they affect children is severely understudied. Further, common instruments for assessing cybersickness, such as the text-based simulator sickness questionnaire (SSQ), may not be suitable for use with children, as some of its questions (e.g., fullness of head, stomach awareness, etc.) can be difficult for children to comprehend. The first objective of this project is to implement a child-friendly SSQ that leverages children's visual skills by augmenting the SSQ with animations of the symptoms. The effectiveness of the visual questionnaire versus the text-based SSQ will be studied as a part of the first objective and released for use by other VR researchers and designers. The second objective is to compare both subjective (i.e., the SSQ) and physiological (including rate variability, electroencephalograms, and galvanic skin response) measures of cybersickness between children and adults. The last objective is to investigate the factors in a virtual environment that trigger cybersickness in children. An event-related potential analysis of the brain activity in different VR environmental design conditions will identify their effects on cybersickness.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.

近年来，虚拟现实（VR）技术已经变得更加实惠，更容易为不同人群所接受。VR用户面临的最大挑战之一是虚拟现实疾病，也被称为网络病，其中用户会遇到包括眼睛疲劳，头痛，出汗，头部肿胀，定向障碍，眩晕和恶心在内的症状。 虽然导致晕网的因素以及减少晕网的方法已经在成年人中研究了多年，但儿童越来越频繁地使用VR，他们的快速心理发展可能会影响他们体验晕网的机制以及症状的类型和严重程度。 该项目将通过为儿童创造有效的网络病措施，并比较成人和儿童之间网络病的严重程度和驱动因素，调查儿童和成人之间可能存在的差异。实现这些目标将使该团队能够制定为儿童开发安全VR内容的指导方针，从而扩大能够从VR体验中受益的儿童群体。这项研究是第一次彻底调查儿童的电脑病。晕机的原因仍然是有争议的，他们如何影响儿童是严重不足的研究。 此外，用于评估电脑病的常见工具，例如基于文本的模拟器疾病问卷（SSQ），可能不适合用于儿童，因为其中的一些问题（例如，头胀、胃部不适等）对孩子来说很难理解该项目的第一个目标是实施一个儿童友好的SSQ，利用儿童的视觉技能，通过增加SSQ与症状的动画。 视觉问卷与基于文本的SSQ的有效性将作为第一个目标的一部分进行研究，并发布供其他VR研究人员和设计师使用。第二个目标是比较两个主观的（即，SSQ）和生理（包括心率变异性、脑电图和皮肤电反应）测量。 最后一个目标是调查在虚拟环境中的因素，引发儿童的电脑病。通过对不同VR环境设计条件下的大脑活动进行事件相关潜在分析，将确定其对晕电病的影响。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
