HCC: Improving Spatial Perception in Virtual Environments

这个项目使用了一种新的方法，应用感知科学的专业知识来解决创造真实感知的显示器的工程问题。该项目将对视觉确定距离所需的感知信息的复杂理解应用于有效虚拟环境视觉显示的工程设计。距离知觉涉及不同来源的感觉信息之间以及可用视觉信息的不同方面之间的复杂相互作用。这种互动的性质会随着时间的推移而迅速适应。综上所述，这大大增加了我们理解和描述所涉及的过程的能力。虽然感知心理学家多年来一直在以改变深度感知的方式操纵视觉刺激，但我们可以通过一种随时间稳定并满足与虚拟环境应用相关的各种工程限制的方式来做到这一点是新颖的，而且未经测试。该项目本质上是多学科的，涉及计算机科学家和认知心理学家之间的真正合作，并带来了特殊的教育环境。调查人员在让本科生和女性参与研究方面有着良好的记录，并将在这项工作中延续这一传统。犹他大学计算机科学和心理学专业的本科生都直接参与了类似的研究项目，从而产生了高质量的高级论文和期刊论文。

This project uses a novel approach of applying expertise in perceptual science to solve the engineering problem of creating displays that are perceived veridically. This project applies a sophisticated understanding of the perceptual information needed to visually determine distances to the engineering of effective virtual environment visual displays. Distance perception involves a complex interaction between different sources of sensory information and between different aspects of the available visual information. The nature of this interaction rapidly adapts over time. Taken together, this significantly complicates our ability to understand and describe the processes involved. While perceptual psychologists have for many years manipulated visual stimuli in ways that change depth perception, the idea that we can do so in a way that is stable over time and which satisfies a variety of engineering constraints associated with virtual environment applications is novel and untested.The project is intrinsically multidisciplinary, involving genuine collaboration between computer scientists and cognitive psychologists and leading to an exceptional educational environment. The investigators have a well established record of involving undergraduates and women in research and will continue that tradition with this work. Undergraduate students in both computer science and psychology at the University of Utah have been directly involved in research projects similar to this one, leading to high quality senior theses and journal publications.
