Dimensions of perceptual-driven rendering in Virtual Reality

EPSRC研究领域：图形和可视化最近高性能图形技术和消费级头盔显示器的出现意味着沉浸式虚拟现实(VR)在研究、休闲和商业目的中正变得越来越受欢迎。生成虚拟现实体验的计算成本是出了名的昂贵，需求和预期总是超出能力。这个项目的高层次目标是研究人类感知和认知系统的特征，这些特征可以被用来降低VR系统中各个组件的计算成本，从而提高给定硬件的虚拟体验质量。这方面的一个例子将是降低渲染质量作为远离中心凹(人眼视网膜上的焦点)的偏心的函数。主要目标是：为VR流水线建立参考架构定义将感知/认知的特征与参考架构的组件相关联的分类根据感知和认知驱动的VR渲染执行对当前技术状态的系统审查，识别先前成功或失败的区域以及有希望探索的区域在这些区域中进行实验以确定是否可能有有意义的节省/改进。可以确定提出有意义的节省/改进的区域，将重新设计VR管道的组件以体现这些原则，并进行了进一步的实验以证实结果。

EPSRC research area: Graphics and visualisationThe recent availability of high-performance graphics technology and consumer-grade head-mounted-displays has meant that Immersive Virtual Reality (VR) is becoming increasingly popular both for research, leisure and commercial purposes. Generating VR experiences is notoriously computationally expensive, with demand and expectations always outstripping capability. The high level aim of this project is to investigate the features of the human perceptual and cognitive systems that can be exploited to reduce the computational cost on various components of a VR system in order to improve the quality of the virtual experience for given hardware. One example of this would be lowering the rendering quality as a function of eccentricity away from the fovea (focus point on the human eye retina).The main objectives are to:Establish a reference architecture for the VR pipelineDefine a taxonomy that relates features of perception/cognition to components of the reference architecturePerform a systematic review of the current state-of-art in terms of perceptual and cognition driven rendering for VR, identifying areas of previous success or failure and areas for promising explorationConduct experiments in these areas to determine whether meaningful savings/improvements are possibleAssuming areas can be identified that suggest meaningful savings/improvements, components of the VR pipeline will be re-engineered to embody these principles, and further experiments conducted to confirm results.
