In this project, the PI will lead an interdisciplinary team in a quest for fundamental insights into how to effectively harness the full potential of virtual reality technology for visualization and design. The specific focus of the research will be on architectural applications. Within this context, the PI will seek to enable accurate and intuitive spatial understanding of large, immersive 3D virtual environments presented both via head mounted displays and on large projection screens. For environments presented via a head mounted display, the PI will explore how the accuracy of the user's spatial perception and sense of presence is affected by factors such as: providing a faithful representation of the user's body; providing low latency visual and haptic feedback about the sizes and distances from the user of tracked objects that co-exist in both the real and virtual environments; and providing spatialized 3D ambient sound cues. For information presented via a stereoscopic large screen rear-projection system, the PI will explore how the viewer's ability to attain a maximally accurate intuitive spatial understanding of an interior or exterior is impacted by questions such as: the importance of presenting people with an image of a scene that is generated from a viewpoint that is as close as possible to their own eye position, both laterally and in distance from the ground; the conditions under which the viewer is likely to adopt an interpretation of size and distance relationships in a virtual environment shown via a projection system that is based on the assumptions that underlie interpretations of size and distance in pictures, as opposed to interpretations of size and distance in directly viewed scenes; and whether, when considering display on a large screen, bigger is always better, or if the maximum benefit comes from displaying a scene at "life size" with the possibility that negative consequences might arise from displaying things too large. The PI will further explore the design and evaluation of improved metaphors for enabling intuitive locomotion through very large scale immersive virtual environments, as well as the effective use of abstraction for the representation of uncertain or ambiguous information in such environments.Broader Impacts: This work will lead to basic observations and rules of thumb derived from careful human subjects experiments that will inform a broad range of research efforts involving the use of virtual environments, in such domains as scientific and information visualization, situational awareness, and diversity training. It will also result in improvements in architectural education stemming from the effective use of virtual environment technology to teach fundamental concepts in visual imagination and integration of an egocentric perspective into the earliest stages of the design process.

在这个项目中，PI将领导一个跨学科团队，以寻求基本的见解，以实现如何有效利用虚拟现实技术的全部潜力进行可视化和设计。 研究的具体重点将放在建筑应用上。 在这种情况下，PI将寻求对通过头部安装的显示器和大型投影屏幕上呈现的大型，沉浸式3D虚拟环境的准确和直观的空间理解。 对于通过头部安装显示的环境，PI将探讨用户空间感知和存在感的准确性如何受到以下因素的影响：提供对用户身体的忠实表示；提供低延迟的视觉和触觉反馈，内容涉及在真实和虚拟环境中共存的跟踪对象的用户的大小和距离；并提供空间化的3D环境声音提示。 对于通过立体大屏幕后投影系统提供的信息，PI将探索观众如何获得对内部或外部的最大准确直观的直觉空间理解的能力，例如：以下问题受到以下问题的重要性：从以下问题中呈现出人们从视野中产生与后来相距远距离和距离的场景形象的重要性。观看者可能在虚拟环境中通过投影系统显示的大小和距离关系的解释的条件基于图片中大小和距离的解释的基础的假设，而不是直接查看场景中的大小和距离的解释；而且，当考虑在大屏幕上显示显示时，更大的范围总是更好，还是最大收益来自以“生命大小”的形式显示场景，并且显示出太大的东西可能会产生负面后果。 PI将进一步探索改进的隐喻的设计和评估，以通过非常大规模的沉浸式虚拟环境以及有效地使用抽象来表示不确定或歧义的信息在此类环境中的不确定信息。BOADROACHER的影响：这项工作将导致谨慎的范围，这些范围涉及人类的基本观察和规则，这些工作将导致人类的基本范围，从而导致人们的基本范围，从而导致人们的基本范围，从而导致了良好的范围，从而导致了人们的利用，该范围涉及人类的基本范围，从而导致灵活性的范围科学和信息可视化，情境意识和多样性培训等领域。 这也将导致建筑教育的改善，这是由于虚拟环境技术的有效利用来教授视觉想象中的基本概念，并将以自我为中心的观点整合到设计过程的最早阶段。
