The overall theme and long-term goal of this research program is to develop a model of stereoscopic surface perception and its role in visually guided action. Stereoscopic depth or stereopsis arises from processing of the differences or `disparities' between the images in the two eyes and is important for the perception of surface shape, environmental layout and material properties. Such information is, in turn, important for the planning and execution of visually-guided movements including locomotion. The focus of the current proposal is to provide a better understanding of the perceptual cues humans use to make judgements of their environment that support their locomotion. We then apply this knowledge to help evaluate and develop more effective 3D user interfaces.***Recent studies (from our lab and others) and anecdotal reports demonstrate that binocular vision and stereopsis can provide substantial perceptual benefits at distances relevant to the moment-to-moment control of locomotion. In the current proposal I address the role of stereopsis in guidance of locomotion in real and computer-mediated environments with these short-term objectives: ***1) Investigating the role of stereoscopic vision in perceptual decision making including in the perception of our self motion and of the layout of the world through which we move. ***2) Understanding how these perceptions affect the control and guidance of locomotion, path planning and navigating.***3) Assessing the implications in information display and for aiding virtual reality (VR) and augmented reality (AR) locomotion. We will develop design rules, guidelines and techniques for generation of stereoscopic imagery to support AR locomotion.***Given that the role of stereopsis in locomoting, orienting and navigating has not been well studied, in a series of foundational experiments we will extend our work on scene perception to the control of locomotor action. In particular we will examine the role that binocular vision plays in performing real world tasks such as ramp walking and walking on rough terrain. These experiments will be enabled by availability of state-of the art facilities such as our unique wide-field stereoscopic display.***This basic research will provide insight for developing effective 3D user interfaces, particularly in VR and AR. We will extend our work on the role of stereoscopic cues in the perception of self-motion and cognitive mapping in the real world and apply it to abstract and naturalistic 3D locomotion. Based on these experiments, we will recommend ways to augment real and virtual environments to support and extend these capabilities. The research will enable safer, more effective and more natural user interfaces for low vision aids, vehicular displays and other applications. Highly-qualified researchers will be trained on skills in human-computer interaction and visualization that are highly sought after by Canadian industry.

该研究计划的总体主题和长期目标是开发一个立体表面感知的模型及其在视觉指导作用中的作用。立体深度或立体声是由两只眼睛中图像之间的差异或“差异”的处理引起的，对于感知表面形状，环境布局和材料特性很重要。反过来，此类信息对于计划和执行视觉引导的运动（包括运动）至关重要。当前建议的重点是更好地理解人类用来判断​​其环境以支持其运动的感知线索。然后，我们运用这些知识来帮助评估和开发更有效的3D用户界面。***最近的研究（来自我们的实验室和其他人），轶事报告表明，双眼视觉和立体曲线可以在与移动的时刻控制时刻相关的距离时提供实质性的感知益处。在当前的提案中，我解决了立体动物在具有这些短期目标的真实和计算机介导的环境中的指导运动中的作用：*** 1）研究立体视觉在感知决策中的作用，包括感知我们的自我运动以及我们移动的世界局面。 *** 2）了解这些看法如何影响运动，路径计划和导航的控制和指导。*** 3）评估信息显示中的含义以及帮助虚拟现实（VR）和增强现实（AR）运动。我们将制定设计规则，准则和技术来生成立体图像以支持AR的运动。***鉴于立体相关的作用在运动，定向和导航中的作用尚未得到很好的研究，在一系列的基础实验中，我们将扩展我们在场景上的工作感知，以扩展我们的工作。特别是，我们将研究双眼视力在执行现实世界任务中所扮演的角色，例如在崎rough的地形上行走和行走。这些实验将通过可用的最先进的设施（例如我们独特的宽场立体显示屏）来实现。我们将扩展有关立体提示在对现实世界中自我运动和认知映射感知中的作用的工作，并将其应用于抽象和自然主义的3D运动。根据这些实验，我们将建议方法来增强实际和虚拟环境以支持和扩展这些功能。这项研究将使低视力辅助工具，车辆显示器和其他应用使更安全，更有效，更自然的用户界面。备受合格的研究人员将接受加拿大工业备受追捧的人类计算机互动和可视化技能的培训。
