This is an equipment grant to purchase eye-tracking and display technology to support multidisciplinary research on the use of virtual environments as a medium for the study of human behavior. The research program uses an immersive, interactive bicycling simulator to study how child and adult cyclists make decisions about crossing traffic-filled roads, and a large-screen immersive display system to study spatial perception in real and virtual environments. Using the new instrumentation, the project will: 1) Integrate an eye-tracking and head-tracking system with the existing interactive bicycling simulator to conduct studies of visual attention during road crossing, 2) Test how projecting stereo images and a ground surface adds to the realism and effectiveness of a large-screen display system, and 3) Compare a large-screen display system with a head-mounted display system to investigate how display characteristics impact spatial perception.New instrumentation will expand current facilities in four important ways: 1) adding eye tracking to the high fidelity bicycling simulator, 2) upgrading large screen displays with stereo projection, 3) adding a ground display to the bicycling simulator, and 4) acquiring a head-mounted display system. By increasing and testing the realism and effectiveness of different types of immersive, interactive virtual environments, and developing new computational techniques for integrating virtual environment technology with other cutting-edge technologies, research using this infrastructure will advance the development of state-of-the-art virtual environments as laboratories for the study of human behavior.The research made possible by this infrastructure will contribute to both our understanding of the development of perception-action coupling during late childhood and early adolescence and to our understanding of the underlying causes of child bicycling injuries. The results will lay a foundation for future intervention studies designed to reduce car-bicycle collisions. Advances made on this project in simulation technology, in experimental methodology, and in our understanding of distance perception will contribute to the development of virtual environments for use in behavioral research. This research will also have impact on interactive simulation technology for training, teaching, and entertainment purposes. Finally, this project will promote multidisciplinary training by providing collaborative research experience to a diverse group of undergraduate students, graduate students, and postdocs in psychology and computer science.

这是一项设备赠款，用于购买眼动跟踪和显示技术，以支持使用虚拟环境作为人类行为研究媒介的多学科研究。该研究计划使用沉浸式交互式自行车模拟器来研究儿童和成人骑自行车者如何决定穿越交通拥挤的道路，以及大屏幕沉浸式显示系统来研究真实的和虚拟环境中的空间感知。使用新的仪器，该项目将：1）将眼睛跟踪和头部跟踪系统与现有的交互式自行车模拟器集成，以进行道路交叉口期间视觉注意力的研究，2）测试投影立体图像和地面如何增加大屏幕的真实性和有效性显示系统，3）比较大屏幕显示系统和头戴式显示系统，以研究显示特性如何影响空间感知。新仪器将在四个重要方面扩展现有设施：1）为高保真自行车模拟器添加眼睛跟踪，2）升级具有立体投影的大屏幕显示器，3）为自行车模拟器添加地面显示器，以及4）获得头戴式显示系统。通过增加和测试不同类型的沉浸式、交互式虚拟环境的真实性和有效性，并开发新的计算技术，将虚拟环境技术与其他尖端技术相结合，利用这一基础设施的研究将促进国家的发展，艺术虚拟环境作为人类行为研究的实验室。这种基础设施使研究成为可能，将有助于我们理解儿童晚期和青春期早期知觉-行动耦合的发展，以及我们对儿童骑自行车受伤的根本原因的理解。研究结果将为未来旨在减少汽车与自行车碰撞的干预研究奠定基础。该项目在仿真技术、实验方法和我们对距离感知的理解方面取得的进展将有助于开发用于行为研究的虚拟环境。这项研究也将对用于培训、教学和娱乐目的的交互式仿真技术产生影响。最后，该项目将通过为心理学和计算机科学的本科生、研究生和博士后提供合作研究经验，促进多学科培训。
