HCC: Improving Spatial Perception in Virtual Environments

该项目采用了一种新颖的方法，应用感知科学的专业知识来解决创造真实感知的显示的工程问题。该项目应用了对视觉上确定距离所需的感知信息的复杂理解，以有效的虚拟环境视觉显示工程。距离感知涉及不同感官信息来源和不同视觉信息之间复杂的相互作用。随着时间的推移，这种交互的性质会迅速适应。综上所述，这极大地复杂化了我们理解和描述相关过程的能力。虽然知觉心理学家多年来一直以改变深度感知的方式操纵视觉刺激，但我们可以以一种稳定的方式做到这一点，并满足与虚拟环境应用相关的各种工程限制，这种想法是新颖的，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，并导致一个特殊的教育环境。研究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，并发表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.
