CISE Research Resources: A State-of-the-Art Immersive Display for Research in Rendering, Animation and Simulation, and Cognitive Human-Computer Interface Design

这个项目将在弗吉尼亚大学建造一个最先进的沉浸式展览。具体来说，研究人员将建立一个宽视场平铺显示器，使用被动立体投影、6自由度头部跟踪和空间化音频来创建一个非常身临其境的3d视听显示环境。这种显示器将使计算机科学和心理学系的三个独立研究项目受益，并使之成为可能：凝视导向渲染、感知驱动的物理模拟和动画，以及人机界面的认知设计。平铺多个投影仪将创建一个显示跨越非常宽的视野；每个瓷砖两个投影仪将使被动式立体显示与轻型偏光眼镜。音频系统、头部跟踪器和逼真的3d扫描环境将使沉浸式和令人信服的虚拟世界成为可能。宽视场将为视线导向渲染提供理想的测试平台，它通过利用降低的视觉灵敏度（例如，对于外围或快速移动的物体）来加速交互式渲染，以及感知驱动的物理模拟，根据感知度量选择性地降低模拟精度。人机界面项目研究沉浸式环境环境以改善人类记忆。新显示器的立体头部跟踪功能将为调查增加一个新的维度，实现全3d环境线索。

EIA-0130800 David LuebkeUniversity of VirginiaThis project will construct a state-of-art immersive display at the University of Virginia. Specifically, the investigators will build a wide field-of-view tiled display, using passive stereo projection, 6-DOF head tracking, and spatialized audio to create an extremely immersive 3-D audio-visual display environment. This display will benefit and enable three separate research projects in the Computer Science and Psychology departments: gaze-directed rendering, perceptually driven physical simulation and animation, and cognitive design of human-computer interfaces. Tiling multiple projectors will create a display spanning a very wide field of view; two projectors per tile will enable passive stereo display with lightweight polarizing glasses. An audio system, a head tracker, and realistic scanned 3-D environments will enable immersive and convincing virtual worlds. The wide field-of-view will provide an ideal testbed for gaze-directed rendering, which accelerates interactive rendering by exploiting reduced visual acuity (e.g., for peripheral or fast-moving objects), and for perceptually driven physical simulation, which selectively degrades simulation accuracy according to perceptual metrics. The human-computer interface project investigates immersive ambient context to improve human memory. The stereo head-tracked capabilities of the new display will literally add a new dimension to the investigation, enabling full 3-D environmental cues.
