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.

这个项目使用了一种新颖的方法，应用感知科学的专业知识来解决创建真实感知的显示器的工程问题。这个项目应用了一个复杂的理解所需的感知信息，以确定有效的虚拟环境视觉显示的工程距离。距离感知涉及不同感官信息源之间以及可用视觉信息的不同方面之间的复杂相互作用。这种相互作用的性质随着时间的推移而迅速适应。总的来说，这大大提高了我们理解和描述所涉及过程的能力。虽然知觉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，但我们可以以一种随时间推移而稳定的方式来这样做，并且满足与虚拟环境应用相关的各种工程约束的想法是新颖的，未经验证的。该项目本质上是多学科的，这涉及到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拥有良好的记录，并将在这项工作中延续这一传统。犹他州大学计算机科学和心理学专业的本科生直接参与了类似的研究项目，导致了高质量的高级论文和期刊出版物。
