Virtual reality (VR) encompasses an array of technologies that directly interface with people, either by replacing or enhancing their perception of the surrounding world. Though these technologies were once science fiction, they are now becoming both affordable and widely available, lending themselves to use in everything from entertainment to medical practice. However, current VR technologies are sometimes not well-matched to people's physical and perceptual characteristics; these mismatches can make VR experiences worse, even to the point of being unusable for some people. This project seeks to advance VR research by combining insights from computer science, neuroscience, and ophthalmology to improve the coupling between VR systems and people's perceptual abilities and physical features. Blending these different perspectives will make it possible to find new and innovative ways to improve VR technologies while better understanding human vision. This project adopts a comprehensive perspective on the relationship between humans and VR technology. Fundamentally, the imagery presented in VR undergoes a series of distinct transformations including rendering, classical optics, physiological optics, sensation, perception, cognition, and resulting actions. Understanding the nuanced contributions of each stage necessitates embracing methods not traditionally associated with VR research, such as integrating ophthalmic eye models, neuroimaging techniques, computer numerical control systems, and others. For instance, leveraging ophthalmic models allows for the creation of virtual scenes customized to individuals' unique eye structure, enabling enhanced spatial fidelity. Additionally, employing neuroimaging in conjunction with spatial judgment tasks will aid in identifying neural distinctions between perceptions of real and virtual scenes. By employing these methods, this project aims to not only advance the development of high-fidelity virtual environments but also unveil novel approaches to studying human spatial vision. The project team will also develop new interdisciplinary course materials for university students and workshops for middle and high school students that seek to attract a wide variety of students to learn about VR, perception, and their intersection.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）涵盖了一系列技术，这些技术是通过更换或增强对周围世界的看法而直接与人接触的。尽管这些技术曾经是科幻小说，但现在它们既实惠又广泛地可用，从娱乐到医疗实践中都可以使用自己。但是，当前的VR技术有时与人们的身体和感知特征相匹配。这些不匹配可以使VR的体验变得更糟，甚至对于某些人来说是无法使用的。该项目旨在通过结合来自计算机科学，神经科学和眼科的见解来提高VR研究，以改善VR系统与人们的感知能力和身体特征之间的耦合。融合这些不同的观点将使找到新的创新方法来改善VR技术，同时更好地了解人类的视野。该项目对人类与VR技术之间的关系采取了全面的看法。从根本上讲，VR中提出的图像经历了一系列不同的转换，包括渲染，古典光学，生理光学，感觉，感知，认知和结果作用。了解每个阶段的细微贡献都需要采用传统上与VR研究无关的方法，例如整合眼科眼模型，神经影像学技术，计算机数值控制系统等。例如，利用眼科模型允许创建针对个人独特的眼睛结构定制的虚拟场景，从而实现了增强的空间保真度。此外，在空间判断任务中使用神经影像将有助于确定对真实场景和虚拟场景的看法之间的神经区别。通过采用这些方法，该项目不仅旨在推动高保真虚拟环境的发展，而且还揭示了研究人类空间视力的新颖方法。该项目团队还将为大学生和中学生研讨会开发新的跨学科课程材料，这些课程旨在吸引各种学生来了解VR，感知和他们的交集。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子和更广泛影响的评估来评估CRITERIA的评估。
